Description

本発明は、容器の口部に装着されるヒンジキャップに関し、特に、注出側に垂れた液を簡単に拭き取ることができるヒンジキャップに関するものである。 The present invention relates to a hinge cap that is attached to the mouth of a container, and in particular to a hinge cap that allows liquid that drips onto the pouring side to be easily wiped off.

従来から、廃棄時に、開蓋した上蓋を引き上げることにより、容器からキャップ本体を分離する分別機構を備えるヒンジキャップが知られている。
この種のヒンジキャップでは、容器の口部に嵌合する筒部を破断するための種々の構造が提案されているが、容器口部に嵌合保持するための強度やシール性との兼ね合いから、当該筒部を破断する際にかなりの力を必要とした。 2. Description of the Related Art Conventionally, hinge caps have been known that are provided with a separation mechanism that separates a cap body from a container by lifting an open top lid at the time of disposal.
For this type of hinge cap, various structures have been proposed for breaking the tubular portion that fits into the mouth of the container, but due to the balance between the strength and sealing ability required to fit and hold the cap into the mouth of the container, a considerable amount of force is required to break the tubular portion.

このため、キャップ本体には、容器の口部との嵌合部をはさんで垂設された外筒および内筒と、外筒と内筒とに連設するとともに上蓋との係合部を上部に有する係合リングとを備える嵌合筒部を設け、ヒンジに連設する外筒には、ヒンジの近傍に縦方向に切り込み部が設けられた縦方向引き裂きラインが設けられ、外筒と係合リングの間には、縦方向引き裂きラインから所定円周角の円弧範囲にわたって上方に開口を有するスリット溝が設けられており、スリット溝の底面には、外筒と係合リングを連結する薄肉の連結部からなる周方向引き裂きラインが、縦方向引き裂きラインに接続して設けられているヒンジキャップが知られている（例えば、特許文献１参照）。 For this reason, a hinge cap is known in which the cap body is provided with an outer tube and an inner tube suspended on either side of a fitting portion for the mouth of the container, and an engagement ring connected to the outer tube and inner tube and having an engagement portion at its upper part for engaging with the top lid, the outer tube connected to the hinge is provided with a vertical tear line with a vertical cut portion near the hinge, and a slit groove is provided between the outer tube and the engagement ring, the slit groove having an opening upward over an arc range of a predetermined circumferential angle from the vertical tear line, and a circumferential tear line consisting of a thin-walled connecting portion that connects the outer tube and the engagement ring is provided on the bottom surface of the slit groove, connected to the vertical tear line (see, for example, Patent Document 1).

しかしながら、特許文献１記載のヒンジキャップでは、キャップ本体の注出筒からの注出時に、内容液が垂れてキャップ本体の嵌合筒部上面に形成されたスリット溝内に溜まり、簡単に拭き取ることができず、衛生上好ましくないという問題があった。 However, with the hinge cap described in Patent Document 1, when the liquid contents are poured from the pouring tube of the cap body, they drip and accumulate in the slit groove formed on the upper surface of the fitting tube of the cap body, and this cannot be easily wiped off, which is unhygienic.

本発明は、上記問題を解決することを課題とし、内容液の注出時に、液がキャップ本体の注出側に垂れても、垂れた液を簡単に拭き取ることができるヒンジキャップを提供することを目的とする。 The present invention aims to solve the above problem by providing a hinge cap that allows the dripping liquid to be easily wiped off even if the liquid drips onto the pouring side of the cap body when the liquid contents are poured out.

本発明は、上記の課題を解決するため、ヒンジキャップとして、容器に装着されるキャップ本体と、キャップ本体にヒンジを介して取り付けられる蓋体とを備えるヒンジキャップであって、キャップ本体は、容器の口部を挟んで垂設される内筒および外周壁部と、内筒と外周壁部とに連設される基壁部とを有し、外周壁部は、注出側の所定円弧範囲にヒンジ側の上面から所定距離下がった平坦面が形成される段凹部と、ヒンジ側の外周方向に沿って段凹部以外の円弧範囲に立設される背面外壁部と、背面外壁部と基壁部との間に形成され、底面が段凹部の平坦面と連続するスリット溝とを有し、蓋体は、頂壁と、頂壁の周縁から垂設される側周壁と、側周壁の注出側から垂設され、段凹部を覆う被覆壁とを有することを特徴とする構成を採用する。 In order to solve the above-mentioned problems, the present invention provides a hinge cap comprising a cap body to be attached to a container and a lid body attached to the cap body via a hinge, wherein the cap body has an inner tube and an outer peripheral wall portion which are hung across the mouth of the container, and a base wall portion which is connected to the inner tube and the outer peripheral wall portion, the outer peripheral wall portion having a step recess in which a flat surface is formed a predetermined distance below the upper surface of the hinge side in a predetermined arc range on the pouring side, a back outer wall portion which is hung in an arc range other than the step recess along the outer circumferential direction of the hinge side, and a slit groove which is formed between the back outer wall portion and the base wall portion and whose bottom surface is continuous with the flat surface of the step recess, and the lid body has a configuration comprising a top wall, a side wall which hangs down from the periphery of the top wall, and a covering wall which hangs down from the pouring side of the side wall and covers the step recess.

ヒンジキャップの実施形態として、スリット溝は、背面外壁部上面からの深さがヒンジ側から注出側に向けて順次浅くなることを特徴とする構成を採用し、また、スリット溝は、底面が段凹部の平坦面と面一となることを特徴とする構成を採用する。 As an embodiment of the hinge cap, the slit groove is configured so that its depth from the top surface of the rear outer wall portion gradually becomes shallower from the hinge side toward the pouring side, and the slit groove is configured so that its bottom surface is flush with the flat surface of the step recess.

さらに、ヒンジキャップの具体的実施形態として、外周壁部は、ヒンジの近傍からスリット溝の底面に向けて縦方向に形成された縦方向引き裂きラインと、縦方向引き裂きラインからスリット溝の底面に沿って形成された周方向引き裂きラインとからなる分別機構を有することを特徴とする構成を採用する。 Furthermore, as a specific embodiment of the hinge cap, a configuration is adopted in which the outer wall portion has a separation mechanism consisting of a vertical tear line formed vertically from the vicinity of the hinge toward the bottom surface of the slit groove, and a circumferential tear line formed from the vertical tear line along the bottom surface of the slit groove.

本発明のヒンジキャップは、上記構成を採用することにより、内容液の注出時に、液がキャップ本体の注出側に垂れても、注出側に溜まることがないので、垂れた液を簡単に拭き取ることができる。 By adopting the above-mentioned configuration, the hinge cap of the present invention can easily wipe off any dripping liquid, even if the liquid drips onto the pouring side of the cap body when pouring the liquid contents, as it does not accumulate on the pouring side.

また、本発明のヒンジキャップは、スリット溝が、背面外壁部上面からの深さがヒンジ側から注出側に向けて順次浅くなるようにしたので、容器から分別する際に、外周壁部を引っ張る力が上向きとなって力が掛かり易くなり、外周壁部を蓋係合部から容易に切り離すことができる。 In addition, the hinge cap of the present invention has a slit groove whose depth from the top surface of the rear outer wall gradually becomes shallower from the hinge side toward the pouring side, so that when separating the container, the force pulling the outer wall is directed upwards, making it easier to apply force, and the outer wall can be easily separated from the lid engagement part.

次に、本発明のヒンジキャップについて、実施例を示した図面を参照して説明する。
なお、以下の説明において、図１でみて、左方向を「注出側」とし、右方向を「背面側」とし、上方向を「上」とし、下方向を「下」とする。 Next, the hinge cap of the present invention will be described with reference to the drawings showing an embodiment.
In the following description, the left side in FIG. 1 is the "pouring side", the right side is the "rear side", the upper side is the "upper", and the lower side is the "lower".

図１において、Ａは容器、Ｂは容器Ａに装着されるキャップ本体、Ｄはキャップ本体ＢにヒンジＣを介して開閉可能に取り付けられる蓋体である。
容器Ａは、上部に口部１を有し、口部１の外周面上部には、嵌合突条２が設けられ、嵌合突条２の外周上部は傾斜面２ａとなっている。 In FIG. 1, A is a container, B is a cap body attached to the container A, and D is a lid body attached to the cap body B via a hinge C so as to be able to open and close.
Container A has a mouth 1 at its top, and a fitting ridge 2 is provided on the upper outer periphery of mouth 1, the upper outer periphery of which forms an inclined surface 2a.

キャップ本体Ｂは、図１および図２に示すように、容器Ａの口部１に嵌着される装着部３と、装着部３の内縁から内方に延設され、口部１の開口を封鎖する上壁４と、上壁４を貫通する注出口４ａと、注出口４ａから僅かに拡径した径で上壁４の上面に立設される注出筒５とを備えている。
注出筒５は、内容液を注ぎ易くするために、本実施例では、注出側は、背面側（ヒンジＣ側）よりも高く形成され、リップ部５ａは、ラッパ状に広がっている。 As shown in Figures 1 and 2, the cap body B comprises an attachment portion 3 that is fitted into the mouth portion 1 of the container A, an upper wall 4 that extends inward from the inner edge of the attachment portion 3 and seals the opening of the mouth portion 1, a pouring outlet 4a that penetrates the upper wall 4, and a pouring tube 5 that is erected on the upper surface of the upper wall 4 with a diameter slightly wider than the pouring outlet 4a.
In order to make it easier to pour the liquid content, in this embodiment, the pouring side of the pouring tube 5 is formed higher than the back side (the hinge C side), and the lip portion 5a is widened in a trumpet shape.

装着部３は、蓋体Ｄと係合する環状の蓋係合部６と、蓋係合部６の内周側から垂設される内筒７と、蓋係合部６の外周側から垂設される外周壁部８とから構成されており、外周壁部８には、背面側上端にヒンジＣが連設され、内周下部に容器Ａの口部１の嵌合突条２と係合する係合突部９が設けられている。
なお、本実施例では、装着部３は、容器Ａの口部１を挟んで垂設される内筒７および外周壁部８と、内筒７と外周壁部８とに連設される蓋係合部６とから構成されているが、内筒７と外周壁部８とを連設するのは、蓋係合部６に限らず、リング状の基壁部であればよく、この場合には、蓋係合部６は、上壁４の周縁部に設ければよい。 The mounting portion 3 is composed of an annular lid engagement portion 6 that engages with the lid body D, an inner tube 7 that hangs down from the inner side of the lid engagement portion 6, and an outer peripheral wall portion 8 that hangs down from the outer side of the lid engagement portion 6, and a hinge C is connected to the upper end on the back side of the outer peripheral wall portion 8, and an engagement protrusion 9 is provided at the lower inner circumference for engaging with a mating protrusion 2 of the mouth portion 1 of the container A.
In this embodiment, the mounting portion 3 is composed of an inner tube 7 and an outer peripheral wall portion 8 which are vertically arranged across the mouth 1 of the container A, and a lid engagement portion 6 which is connected to the inner tube 7 and the outer peripheral wall portion 8. However, the connection between the inner tube 7 and the outer peripheral wall portion 8 is not limited to the lid engagement portion 6, and any ring-shaped base wall portion can be used, and in this case, the lid engagement portion 6 can be provided on the peripheral portion of the upper wall 4.

蓋係合部６は、背面側の中央から左右に所定の範囲で上壁４上面と面一の高さに切り込まれた切り欠き部１０を残して円弧状に蓋係合突部１１が立設され、切り欠き部１０内には、蓋係合突部１１の両端部から等間隔の隙間を開けて複数配設される背面側突部１２が突設されている。
蓋係合突部１１の外周には係止突条１３が設けられている。 The lid engagement portion 6 has an arc-shaped lid engagement protrusion 11 that stands up, leaving a notch 10 cut into the lid engagement portion 6 from the center of the rear side to the left and right within a specified range at the same height as the upper surface of the upper wall 4, and within the notch 10, multiple rear side protrusions 12 are protruding from both ends of the lid engagement protrusion 11 with equally spaced gaps between them.
The cover engaging projection 11 has a locking projection 13 on its outer periphery.

外周壁部８の上部には、注出側に、ほぼ１８０°の円弧範囲で円弧状に上から距離αの深さで外周から凹設された段凹部１５が設けられ、残りの背面側は、上面８ａが上壁４上面および切り欠き部１０底面と面一の高さとなり、外周上端にヒンジＣが連設される。
段凹部１５は、上面８ａから距離α下がった平坦面１５ａと、平坦面１５ａの内周縁から内側上方に傾斜する傾斜面１５ｂと、平坦面１５ａの端部の両側から上面８ａのそれぞれの両側に向って傾斜する傾斜側面１５ｃとが形成されている。 At the upper part of the outer peripheral wall portion 8, on the pouring side, there is a stepped recess 15 recessed from the outer periphery in an arc shape over a range of approximately 180°, a distance α from above, and on the remaining back side, the upper surface 8a is flush with the upper surface of the upper wall 4 and the bottom surface of the cutout portion 10, and a hinge C is connected to the upper end of the outer periphery.
The step recess 15 is formed with a flat surface 15a that is a distance α below the top surface 8a, an inclined surface 15b that slopes upward and inward from the inner peripheral edge of the flat surface 15a, and inclined side surfaces 15c that slope from both sides of the end of the flat surface 15a toward both sides of the top surface 8a.

図２（ａ）に示すように、外周壁部８のヒンジＣの左近傍には、外周面に平面視で略Ｖ字状の外周切り込み部１６が下端部に薄肉底壁を残して上面８ａから切り込まれている。
外周壁部８内周の係合突部９の外周切り込み部１６に対応する位置には、図示しないが内周切り込み部が縦方向に刻設され、該部分の外周壁部８は内外から切り込まれ、薄肉となる縦方向引き裂きラインを構成する縦弱化部１７が形成される。 As shown in FIG. 2A, near the left of the hinge C of the outer peripheral wall portion 8, an outer peripheral cut portion 16 having a generally V-shape in plan view is cut into the outer peripheral surface from the upper surface 8a, leaving a thin bottom wall at the lower end.
At a position corresponding to the outer peripheral notch 16 of the engaging protrusion 9 on the inner circumference of the outer peripheral wall portion 8, an inner peripheral notch (not shown) is engraved vertically, and the outer peripheral wall portion 8 in that portion is cut from inside and outside to form a vertical weakened portion 17 that constitutes a vertical tear line that thins the wall.

外周壁部８の背面側の外周切り込み部１６よりヒンジＣ側では、図２に示すように、端面１６ａの内周側の上部の薄肉部を隔てた位置を起点として円周方向に延びて上面８ａ右端側の段凹部１５の傾斜側面１５ｃまでと、さらに、段凹部１５の先の傾斜側面１５ｃから外周切り込み部１６の近傍まで、スリット溝１８が上面８ａから凹設され、また、外周壁部８の外周切り込み部１６のヒンジＣと反対側の上面８ａは、外周壁部８上部と蓋係合部６下部とが一体に連結した肉厚部１９となっている。 On the hinge C side of the outer circumferential cutout 16 on the back side of the outer circumferential wall 8, as shown in FIG. 2, a slit groove 18 is recessed from the upper surface 8a, starting from a position separated by the thin portion of the upper inner circumferential side of the end face 16a, extending in the circumferential direction to the inclined side surface 15c of the step recess 15 on the right end side of the upper surface 8a, and further from the inclined side surface 15c of the step recess 15 to the vicinity of the outer circumferential cutout 16. Also, the upper surface 8a on the opposite side of the hinge C of the outer circumferential cutout 16 of the outer circumferential wall 8 is a thick portion 19 that integrally connects the upper portion of the outer circumferential wall 8 and the lower portion of the lid engagement portion 6.

図３（ａ）に示すように、スリット溝１８の底面２０は、端面１６ａ側からヒンジＣ（背面側）の中央部（図２のＯ－Ｘ１線）までが底面２０ａとして、上面８ａから距離βと一番深く凹設され、図３（ｂ）に示すように、ヒンジＣの中央部から右側に向かって４５°付近（図２のＯ－Ｘ２線）が底面２０ｂとなり、さらに、図３（ｃ）に示すように、ヒンジＣの中央部から右側に向かって６０°付近（図２のＯ－Ｘ３線）が底面２０ｃとなり、上面８ａからの高さが距離βから徐々に浅くなるように形成され、最後は、図３（ｄ）に示すように、ヒンジＣの中央部から右側に向かって９０°付近（図２のＯ－Ｘ４線）の段凹部１５の傾斜側面１５ｃを切り欠いて距離αの平坦面１５ａ端部まで連なるよう形成されており、底面２０の内周側は、図２および図３に示すように、端面１６ａ側からヒンジＣの中央部までの外周壁部８と蓋係合部６の下方の壁部分を連結する薄肉の下横弱化部２１となり、ヒンジＣの中央部から９０°付近まで、上方に傾斜する底面２０の内周縁から内側上方に向かって傾斜する円弧状の連結部２２が設けられている。
また、外周壁部８の背面側のスリット溝１８より外側部は、スリット溝１８の底面２０から上面８ａまで立設する背面外壁部２３となり、背面外壁部２３の外周上端の所定の位置にヒンジＣが連設される。 As shown in FIG. 3(a), the bottom surface 20 of the slit groove 18 is recessed deepest from the top surface 8a by a distance β from the end surface 16a side to the center of the hinge C (rear side) (line O-X1 in FIG. 2) as bottom surface 20a, as shown in FIG. 3(b) the bottom surface 20b is located near 45° (line O-X2 in FIG. 2) from the center of the hinge C toward the right side, and further as shown in FIG. 3(c) the bottom surface 20c is located near 60° (line O-X3 in FIG. 2) from the center of the hinge C toward the right side, and is formed so that the height from the top surface 8a gradually becomes shallower from the distance β, and finally the bottom surface 20a is located near 45° (line O-X2 in FIG. 2) from the center of the hinge C toward the right side, and the height from the top surface 8a gradually becomes shallower from the distance β, as shown in FIG. 3(d), the inclined side surface 15c of the step recess 15 is cut out from the center of the hinge C toward the right at approximately 90° (line O-X4 in FIG. 2) and is formed to be continuous to the end of the flat surface 15a at a distance α, and the inner peripheral side of the bottom surface 20, as shown in FIGS. 2 and 3, forms a thin-walled lower lateral weakened portion 21 that connects the outer peripheral wall portion 8 from the end face 16a side to the center of the hinge C to the lower wall portion of the lid engagement portion 6, and an arc-shaped connecting portion 22 is provided that inclines inwardly and upwardly from the inner peripheral edge of the bottom surface 20 that inclines upward from the center of the hinge C to approximately 90°.
In addition, the portion of the outer peripheral wall portion 8 outside the slit groove 18 on the rear side constitutes a rear outer wall portion 23 that stands upright from the bottom surface 20 of the slit groove 18 to the upper surface 8a, and a hinge C is connected to a predetermined position at the upper outer peripheral end of the rear outer wall portion 23.

外周壁部８の内周上部には、左側から背面側中央まで、図２および図３（ａ）に示すように、下横弱化部２１より上部から内側上方に傾斜して、容器Ａに装着時に嵌合突条２の傾斜面２ａに当接する当接面部２４が形成され、背面側中央から右側に、図２（ａ）、図３（ｂ）および図３（ｃ）に示すように、傾斜する底面２０の高さから上に、外側の連結部２２の外側面と平行に内側上方に傾斜するとともに容器Ａに装着時に嵌合突条２の傾斜面２ａから離れるように形成される平行面２５が設けられ、平行面２５と連結部２２外面との間は薄肉となって傾斜連結弱化部２６が形成され、注出側には、段凹部１５の範囲で図１、図２および図３（ｄ）に示すように、蓋係合部６の下面外周縁に下から上向き凹部２７が凹設され、上向き凹部２７と段凹部１５の傾斜側面１５ｃとの間は薄肉となって上横弱化部２８が形成される。
また、下横弱化部２１、傾斜連結弱化部２６および上横弱化部２８は、順に連続するように形成され、周方向引き裂きラインを構成している。 At the upper inner periphery of the outer peripheral wall portion 8, as shown in Figs. 2 and 3(a), from the left side to the center of the rear side, a contact surface portion 24 is formed which is inclined inward and upward from above the lower lateral weakened portion 21 and comes into contact with the inclined surface 2a of the fitting protrusion 2 when the container A is attached to the container A. From the center of the rear side to the right side, as shown in Figs. 2(a), 3(b) and 3(c), a contact surface portion 24 is formed which is inclined inward and upward from the height of the inclined bottom surface 20 upward and parallel to the outer surface of the outer connecting portion 22 and comes into contact with the container A. A parallel surface 25 is provided which is formed so as to move away from the inclined surface 2a of the mating protrusion 2 when the cap is attached to the lid, and the portion between the parallel surface 25 and the outer surface of the connecting portion 22 is thin-walled to form an inclined connection weakened portion 26. On the pouring side, as shown in Figures 1, 2 and 3(d), an upward recess 27 is recessed from below into the outer peripheral edge of the lower surface of the lid engaging portion 6 within the range of the step recess 15, and the portion between the upward recess 27 and the inclined side surface 15c of the step recess 15 is thin-walled to form an upper lateral weakened portion 28.
The lower lateral weakened portion 21, the inclined connecting weakened portion 26 and the upper lateral weakened portion 28 are formed in sequence and continuous to each other, forming a circumferential tear line.

蓋体Ｄは、図１および図２に示すように、キャップ本体Ｂの外周壁部８の外周上端に、ヒンジＣを介して回動自在に取着されており、頂壁３０と、頂壁３０の周縁から垂設される側周壁３１と、頂壁３０の裏面から垂設され、注出筒５を密封する密封筒３２とが設けられている。
頂壁３０には、密封筒３２の外周側に変形可能な薄肉部３３が周設されている。 As shown in Figures 1 and 2, the lid body D is rotatably attached to the upper outer end of the outer wall portion 8 of the cap body B via a hinge C, and is provided with a top wall 30, a side wall 31 extending vertically from the periphery of the top wall 30, and a sealing tube 32 extending vertically from the back surface of the top wall 30 to seal the pouring tube 5.
The top wall 30 is provided with a deformable thin-walled portion 33 on the outer periphery of the sealing cylinder 32 .

側周壁３１の下端部内周には、蓋係合部６の蓋係合突部１１と係合して閉蓋状態を維持する係合凹部３５が周設されている。
係合凹部３５は、内向き面に、蓋係合突部１１の係止突条１３と係合する係止部３６が設けられ、下向き面３５ａは、蓋係合突部１１の上面および背面側突部１２の上面と当接するようになっている。
また、側周壁３１の係合凹部３５より内側に、注出側中央部付近を除いて、閉蓋時に蓋係合突部１１の内周上部と当接して側周壁３１が外側に広がらないようにする係止凸片３７が複数配設されている。 An engagement recess 35 is provided around the inner periphery of the lower end of the side peripheral wall 31 to engage with the lid engagement protrusion 11 of the lid engagement portion 6 to maintain the lid in the closed state.
The engagement recess 35 has an engagement portion 36 on its inward surface that engages with the engagement protrusion 13 of the lid engagement protrusion 11, and its downward surface 35a is adapted to abut against the upper surface of the lid engagement protrusion 11 and the upper surface of the rear side protrusion 12.
In addition, multiple locking protrusions 37 are arranged inside the engagement recess 35 of the side wall 31, except near the center of the pouring side, to abut against the upper inner periphery of the lid engagement protrusion 11 when the lid is closed to prevent the side wall 31 from spreading outward.

側周壁３１の外周には、注出側の下部に、周方向に円弧状の摘み部３８が形成され、背面側の下端部にヒンジＣが連設されている。
側周壁３１下面の注出側外周縁には、閉蓋時にキャップ本体Ｂの外周壁部８の段凹部１５を覆うように、段凹部１５の平坦面１５ａに、下端が近接あるいは当接するように形成された円弧状の被覆壁３９が垂設されている。 A knob 38 having an arc shape is formed in the circumferential direction at the lower part on the spout side on the outer periphery of the side wall 31, and a hinge C is connected to the lower end part on the back side.
An arc-shaped covering wall 39 is vertically attached to the pouring side outer edge of the underside of the side wall 31, and is formed so that its lower end is close to or abuts the flat surface 15a of the step recess 15 so as to cover the step recess 15 of the outer wall portion 8 of the cap body B when the lid is closed.

密封筒３２は、閉蓋時に注出筒５の内周面に挿入されて密封状態とする通常のシール部ａが形成されるとともに、密封筒３２の下部外周側が縮径された下部シール筒３２ａが設けられ、下部シール筒３２ａは、閉蓋時において、上壁４の注出口４ａの内周面に近接あるいは当接するように形成されており、下部シール筒３２ａと注出口４ａの内周面とで、シール部ａの下にもう一つの仮シール部ｂが形成される。 The sealing tube 32 has a normal seal portion a that is inserted into the inner circumferential surface of the pouring tube 5 when the lid is closed to create a sealed state, and a lower seal tube 32a is provided with a reduced diameter on the lower outer circumferential side of the sealing tube 32. The lower seal tube 32a is formed so that it is close to or in contact with the inner circumferential surface of the pouring outlet 4a of the upper wall 4 when the lid is closed, and another temporary seal portion b is formed below the seal portion a by the lower seal tube 32a and the inner circumferential surface of the pouring outlet 4a.

シール部ａと仮シール部ｂとの二段のシールでヒンジキャップが密封されるので、衝撃により、片方のシール部が外れる場合にも、他方のシール部によりシールされ、内容液が漏れることがない。
また、シール部ａと仮シール部ｂとの間に空間ｃが設けられ、容器Ａの落下等による衝撃を受けて、仮シール部ｂに少量の内容液が侵入したときの空間ｃに内容液をとどめることができる。 The hinge cap is sealed with two seals, the seal part a and the temporary seal part b, so that even if one seal part comes off due to impact, the other seal part will seal and the content liquid will not leak.
In addition, a space c is provided between the sealed portion a and the temporary sealed portion b, so that when a small amount of liquid contents enters the temporary sealed portion b due to an impact such as when the container A is dropped, the liquid contents can be contained in the space c.

本実施例のヒンジキャップに、使用前の不正開封を防止するために、図示していないが、キャップ本体Ｂと蓋体Ｄとの間にシュリンクラベルや封緘部材等が設けられていてもよい。 In order to prevent unauthorized opening before use, the hinge cap of this embodiment may be provided with a shrink label or sealing member between the cap body B and the lid body D (not shown).

次に、本実施例の使用態様と作用効果について説明する。
本実施例のヒンジキャップは、最初に、図２に示す状態で一体成形され、蓋体ＤをヒンジＣを介して回動し、キャップ本体Ｂに被せ、図１に示すように、閉蓋する。 Next, the manner of use and the effects of this embodiment will be described.
The hinge cap of this embodiment is first integrally molded in the state shown in FIG. 2, and then the cover body D is rotated via the hinge C to cover the cap body B, and closed as shown in FIG.

その際、蓋体Ｄの密封筒３２の下部外周面が、キャップ本体Ｂの注出筒５の下部内周面に密着してシール部ａとなる。
また、蓋体Ｄの側周壁３１の係合凹部３５とキャップ本体Ｂの蓋係合部６の蓋係合突部１１が係合し、閉蓋が維持される。 At this time, the outer peripheral surface of the lower part of the sealing tube 32 of the lid body D comes into close contact with the inner peripheral surface of the lower part of the pouring tube 5 of the cap body B to form a seal portion a.
Furthermore, the engaging recess 35 of the side peripheral wall 31 of the lid body D and the lid engaging projection 11 of the lid engaging portion 6 of the cap body B engage with each other, maintaining the lid closed.

本実施例のヒンジキャップは、閉蓋して密封した後、密封したシールのリーク検査を行った際、キャップ本体Ｂの注出口４ａに向けて下方からエアーを流し、キャップ本体Ｂの注出筒５と蓋体Ｄの密封筒３２とのシールに不良があった場合、注出筒５より外方に漏れたエアーが、蓋体Ｄの係合凹部３５の下向き面３５ａと当接するキャップ本体Ｂの蓋係合部６の背面側突部１２を除いた切り欠き部１０の間からエアーが流れ、係合凹部３５の内向き面と背面側突部１２の外側面との間から外にエアーが出て判るので、シール不良を判定し易くなっている。 When the hinge cap of this embodiment is closed and sealed, and then a leak test is performed on the sealed seal, air is allowed to flow from below toward the spout 4a of the cap body B. If there is a defect in the seal between the spout tube 5 of the cap body B and the sealing tube 32 of the lid body D, the air leaking outward from the spout tube 5 flows between the cutout portion 10, excluding the rear projection 12, of the lid engagement portion 6 of the cap body B that abuts against the downward surface 35a of the engagement recess 35 of the lid body D, and the air escapes to the outside between the inward surface of the engagement recess 35 and the outer surface of the rear projection 12, making it easy to determine whether there is a seal defect.

次に、図１に示すように、閉蓋したヒンジキャップは、内容液が充填された容器Ａの口部１に打栓して装着される。
打栓工程は、装着部３の内筒７と外周壁部８との間に形成された環状溝に容器Ａの口部１を当てがい、蓋体Ｄの上から押圧力が加えられ、外周壁部８の係合突部９が口部１の嵌合突条２を乗り越えて嵌合し、容器Ａの口部１が内筒７の外周と外周壁部８の内周、および蓋係合部６とによって挟持されることで装着される。 Next, as shown in FIG. 1, the closed hinge cap is attached to the mouth 1 of the container A filled with the liquid content.
In the stoppering process, the mouth 1 of container A is placed into the annular groove formed between the inner tube 7 and outer peripheral wall 8 of the attachment portion 3, and a pressing force is applied from above the lid body D until the engaging protrusion 9 of the outer peripheral wall 8 overcomes the mating protrusion 2 of the mouth 1 and engages with it, and the mouth 1 of container A is clamped between the outer periphery of the inner tube 7, the inner periphery of the outer peripheral wall 8, and the lid engagement portion 6 to attach it.

本実施例のヒンジキャップは、内容液が高温充填された容器Ａに打栓された場合、容器Ａ内の圧力が上昇するが、頂壁３０には密封筒３２の外側に変形可能な薄肉部３３が形成されているので、頂壁３０は、薄肉部３３の内周側のみが上昇して圧力を注出筒５より外側に逃がすので、蓋体Ｄの側周壁３１の係合凹部３５とキャップ本体Ｂの蓋係合部６との係合に支障がなく、閉蓋が維持されるので、内容液が高温だったときの内圧上昇により蓋体Ｄが開蓋してしまうことを防止できる。
また、閉蓋した状態で、倒立落下した際に、蓋体Ｄの頂壁３０に衝撃力が加えられた場合でも、蓋体Ｄが受ける衝撃を薄肉部３３が吸収し、密封筒３２を注出筒５に対して押し込んだり、引き離したりしないので、密封筒３２とキャップ本体Ｂの注出筒５との密着に影響を及ぼさず、密封筒３２と注出筒５との密着が外れたり、密封筒３２と注出筒５が互いに傷付け合ったりすることを防止できる。 When the hinge cap of this embodiment is applied to container A filled with hot liquid, the pressure inside container A rises. However, since the top wall 30 has a deformable thin-walled portion 33 formed on the outside of the sealing tube 32, only the inner side of the thin-walled portion 33 of the top wall 30 rises, releasing the pressure outside the pouring tube 5. This does not interfere with the engagement between the engagement recess 35 of the side wall 31 of the lid body D and the lid engagement portion 6 of the cap body B, and the lid is maintained closed, thereby preventing the lid body D from opening due to an increase in internal pressure when the liquid is hot.
Furthermore, even if an impact force is applied to the top wall 30 of the lid body D when the container is dropped upside down in a closed state, the thin-walled portion 33 absorbs the impact received by the lid body D and the sealing tube 32 is not pushed into or pulled away from the pouring tube 5, so that the tight contact between the sealing tube 32 and the pouring tube 5 of the cap body B is not affected, and it is possible to prevent the sealing tube 32 and the pouring tube 5 from coming loose or from damaging each other.

容器Ａ内の内容液を使用する際には、蓋体Ｄの摘み部３８に手指を掛けて持ち上げると、蓋体Ｄの密封筒３２とキャップ本体Ｂの注出筒５とのシールが外れるとともに蓋体Ｄの側周壁３１とキャップ本体Ｂの蓋係合部６との係合が外され、蓋体Ｄが開蓋され、容器Ａを注出側に傾けると、容器Ａ内の内容液をキャップ本体Ｂの注出口４ａを通じて注出筒５から注出することができる。 When the liquid contents in container A are to be used, the gripping portion 38 of lid body D is hooked with the fingers and lifted up, releasing the seal between the sealing tube 32 of lid body D and the dispensing tube 5 of cap body B, and the engagement between the side peripheral wall 31 of lid body D and the lid engagement portion 6 of cap body B is released, and lid body D is opened. When container A is tilted toward the dispensing side, the liquid contents in container A can be poured out of the dispensing tube 5 through the outlet 4a of cap body B.

本実施例のヒンジキャップは、蓋体Ｄの側周壁３１下面の注出側外周縁に被覆壁３９が設けられているので、閉蓋中にキャップ本体Ｂの外周壁部８の段凹部１５を隠し、また、開蓋の際には摘み部３８の下に掛けた手指がぶつかり、蓋体Ｄの内方に接触することを防止しているので、キャップ内が清潔に保たれる。 The hinge cap of this embodiment has a covering wall 39 on the outer peripheral edge of the pouring side of the underside of the side wall 31 of the lid body D, which hides the stepped recess 15 of the outer peripheral wall 8 of the cap body B when the lid is closed, and prevents fingers hanging under the knob 38 from hitting and touching the inside of the lid body D when the lid is opened, so the inside of the cap is kept clean.

蓋体Ｄをキャップ本体Ｂに再び閉蓋することで、蓋体Ｄの密封筒３２は、外周がキャップ本体Ｂの注出筒５の内周に密着してシールが形成され、容器Ａ内を密封することができ、ヒンジキャップは、繰り返し蓋体Ｄを開閉して使用することができる。 By closing the lid body D again on the cap body B, the outer circumference of the sealing tube 32 of the lid body D comes into close contact with the inner circumference of the dispensing tube 5 of the cap body B to form a seal, sealing the inside of the container A, and the hinge cap can be used by repeatedly opening and closing the lid body D.

本実施例のヒンジキャップは、キャップ本体Ｂの外周壁部８の注出側に平坦面１５ａおよび傾斜面１５ｂを形成した段凹部１５を設けているので、内容液の使用中に容器Ａを傾けた方向の注出筒５のリップ部５ａから液が下の段凹部１５に垂れても、傾斜面１５ｂの傾斜により平坦面１５ａに流れ、また、平坦面１５ａが凹凸のない平面であるためティッシュ等で簡単に汚れを拭き取ることができる。 The hinge cap of this embodiment has a stepped recess 15 with a flat surface 15a and an inclined surface 15b formed on the pouring side of the outer wall 8 of the cap body B. Therefore, even if the liquid drips from the lip 5a of the pouring tube 5 into the lower stepped recess 15 when the container A is tilted during use, the inclination of the inclined surface 15b causes the liquid to flow to the flat surface 15a. Also, since the flat surface 15a is a flat surface without any bumps or irregularities, dirt can be easily wiped off with tissue or the like.

次に、容器Ａ内の内容液を全部使用した後、ヒンジキャップを分別廃棄する態様について説明する。
その際には、ヒンジキャップを開蓋し、蓋体Ｄを指で把持して外方に引っ張ると、ヒンジＣを介して外周壁部８のヒンジＣとの連設部となる背面外壁部２３が引っ張られ、連なる外周壁部８の背面側を引っ張り、変形させていく。
外周壁部８の背面側の引っ張りにより、外周切り込み部１６で形成される縦弱化部１７が破断されていく。
さらに蓋体Ｄを引っ張ると、縦弱化部１７に連設する端面１６ａ側から下横弱化部２１が周方向に切断されていき、次いで連続する傾斜連結弱化部２６が破断し始める。
下横弱化部２１が切断され、傾斜連結弱化部２６の破断が進行すると、図４に示すように、蓋体Ｄおよびそれに連なるキャップ本体Ｂの下横弱化部２１および傾斜連結弱化部２６で区画され、破断された外周壁部８の下側がキャップ本体Ｂから離されていく。 Next, a mode in which the hinge cap is separately disposed of after the liquid content in the container A has been completely used will be described.
In this case, the hinge cap is opened, and the cover body D is grasped with the fingers and pulled outward, whereby the rear outer wall portion 23, which is the connecting portion with the hinge C of the outer peripheral wall portion 8, is pulled via the hinge C, pulling and deforming the rear side of the connected outer peripheral wall portion 8.
As the rear side of the outer peripheral wall portion 8 is pulled, the vertical weakened portion 17 formed by the outer peripheral cut portion 16 is broken.
When the cover body D is further pulled, the lower horizontal weakened portion 21 is cut in the circumferential direction from the end face 16a side connected to the vertical weakened portion 17, and then the continuous inclined connecting weakened portion 26 begins to break.
When the lower lateral weakened portion 21 is cut and the fracture of the inclined connecting weakened portion 26 progresses, as shown in Figure 4, the lower side of the fractured outer peripheral wall portion 8 is separated from the cap body B by the lower lateral weakened portion 21 and the inclined connecting weakened portion 26 of the lid body D and the cap body B connected thereto.

次に、傾斜連結弱化部２６が完全に破断すると、連続する上横弱化部２８が右側端より破断されていき、最後は、段凹部１５を通過して、肉厚部１９で止められる。
さらに、破断された外周壁部８を引っ張ると、連結している外周壁部８の肉厚部１９が外側に引っ張られ、キャップ本体Ｂの外周壁部８の係合突部９と容器Ａの口部１の嵌合突条２との嵌合が外され、そのまま上方に上げると、肉厚部１９で連設されている外周壁部８の上側およびその内方が持ち上げられキャップ本体Ｂが容器Ａの口部１から外されるので、ヒンジキャップと容器Ａとを分別廃棄することができる。 Next, when the inclined connection weakened portion 26 is completely broken, the continuous upper lateral weakened portion 28 is broken from the right end, and finally passes through the step recess 15 and is stopped by the thick portion 19.
Furthermore, when the broken outer wall portion 8 is pulled, the thick portion 19 of the connected outer wall portion 8 is pulled outward, disengaging the engaging protrusion 9 of the outer wall portion 8 of the cap body B from the mating protrusion 2 of the mouth 1 of the container A, and when it is raised in this state, the upper side and its inner side of the outer wall portion 8 connected by the thick portion 19 are lifted and the cap body B is removed from the mouth 1 of the container A, so that the hinge cap and container A can be disposed of separately.

本実施例のヒンジキャップは、傾斜連結弱化部２６を切断する際に、底面２０の傾斜に合わせて下から上の傾斜がついているので、外周壁部８の下部を引っ張る力が上向きとなって力が掛かり易く、また、傾斜連結弱化部２６を形成する内周の平行面２５が容器Ａの嵌合突条２の傾斜面２ａより離れていくので、切断する抵抗が少なくなり、破断し易くなっている。
また、注出側の上横弱化部２８を切断する際に、該部分の内周面の上向き凹部２７が容器Ａの嵌合突条２の傾斜面２ａより完全に離れるので、さらに、切断する抵抗が少なくなり、破断し易くなっている。 In the hinge cap of this embodiment, when the inclined connection weakened portion 26 is cut, the inclined connection weakened portion 26 is inclined from bottom to top to match the inclination of the bottom surface 20, so that the force pulling the lower portion of the outer wall portion 8 is directed upward and the force is easily applied. Also, since the inner parallel surface 25 forming the inclined connection weakened portion 26 moves away from the inclined surface 2a of the mating protrusion 2 of the container A, there is less resistance to cutting, making it easier to break.
In addition, when cutting the upper horizontal weakened portion 28 on the pouring side, the upward recess 27 on the inner surface of said portion is completely separated from the inclined surface 2a of the mating protrusion 2 of the container A, thereby further reducing the resistance to cutting and making it easier to break.

次に、上記第１実施例のキャップ本体Ｂおよび蓋体Ｄを変更した第２実施例について、図を参照して説明する。
以下、第１実施例と同一の構成部分には同一の符号を付し、変更部分に新たな符号を付し、相違点を中心に説明する。 Next, a second embodiment in which the cap body B and the lid body D of the first embodiment are modified will be described with reference to the drawings.
In the following, the same components as those in the first embodiment are given the same reference numerals, changed components are given new reference numerals, and differences will be mainly described.

図５において、Ａは容器、Ｂａは容器Ａに装着されるキャップ本体、Ｄａはキャップ本体ＢａにヒンジＣを介して開閉可能に取り付けられる蓋体である。
キャップ本体Ｂａは、図５および図６に示すように、容器Ａの口部１に装着される装着部４５と、装着部４５の内縁から内方に延設され、口部１の開口を封鎖する上壁４と、上壁４を貫通する注出口４ａと、注出口４ａの僅かに拡径した径で上壁４の上面に立設される注出筒５とを備えている。 In FIG. 5, A is a container, Ba is a cap body attached to the container A, and Da is a lid body attached to the cap body Ba via a hinge C so as to be able to open and close.
As shown in Figures 5 and 6, the cap body Ba comprises an attachment portion 45 that is attached to the mouth portion 1 of the container A, an upper wall 4 that extends inward from the inner edge of the attachment portion 45 and seals the opening of the mouth portion 1, a pouring outlet 4a that penetrates the upper wall 4, and a pouring tube 5 that is erected on the upper surface of the upper wall 4 with a diameter slightly larger than that of the pouring outlet 4a.

装着部４５は、蓋体Ｄａと係合する環状の蓋係合部６と、蓋係合部６の内周側から垂設される内筒７と、蓋係合部６の外周に内周上部が連設される外周壁部４６とから構成されており、外周壁部４６には、背面側上端にヒンジＣが連設され、内周下部に容器Ａの口部１の嵌合突条２と係合する係合突部９が設けられている。 The mounting portion 45 is composed of an annular lid engagement portion 6 that engages with the lid body Da, an inner tube 7 that is suspended from the inner periphery of the lid engagement portion 6, and an outer peripheral wall portion 46 whose upper inner periphery is connected to the outer periphery of the lid engagement portion 6. A hinge C is connected to the upper end of the back side of the outer peripheral wall portion 46, and an engagement protrusion 9 is provided at the lower inner periphery that engages with the mating protrusion 2 of the mouth portion 1 of the container A.

外周壁部４６には、上面４６ａが上壁４上面および切り欠き部１０底面と面一の高さに形成され、注出側に中央から左右に向かいそれぞれ４５°の円弧範囲で円弧状に上から背面側のスリット溝５１の距離βより深い距離γで凹設される切り欠き凹部５０が第１実施例の段凹部１５の代わりに設けられている。 The outer peripheral wall 46 has an upper surface 46a formed flush with the upper surface of the upper wall 4 and the bottom surface of the cutout 10, and a cutout recess 50 is provided on the pouring side in place of the step recess 15 of the first embodiment, recessed in an arc shape from the center to the left and right in a 45° arc range at a distance γ deeper than the distance β of the slit groove 51 on the back side.

切り欠き凹部５０は、上から下に延びる外周面５０ａと、外周面５０ａの下端から外周壁部４６の外周に向かって緩く湾曲する湾曲面５０ｂと、外周面５０ａおよび湾曲面５０ｂの両側から外周壁部４６の外周側面に向かって延びる側面５０ｃとから形成されている。
なお、切り欠き凹部５０は、傾斜面とすることも可能であり、湾曲面と傾斜面を組み合わせてもよい。 The cutout recess 50 is formed from an outer peripheral surface 50a extending from top to bottom, a curved surface 50b that gently curves from the lower end of the outer peripheral surface 50a toward the outer periphery of the outer peripheral wall portion 46, and a side surface 50c that extends from both the outer peripheral surface 50a and the curved surface 50b toward the outer peripheral side surface of the outer peripheral wall portion 46.
The cutout recess 50 may have an inclined surface, or may have a curved surface and an inclined surface in combination.

外周壁部４６のヒンジＣの左近傍には、外周面に平面視で略Ｖ字状の外周切り込み部１６が下端部に薄肉底壁を残して上面４６ａから切り込まれ、外周壁部４６内周の係合突部９の外周切り込み部１６に対応する位置には、薄肉となる縦弱化部１７が形成される。 Near the left of the hinge C of the outer peripheral wall 46, an outer peripheral cutout 16 that is roughly V-shaped in plan view is cut into the outer peripheral surface from the upper surface 46a, leaving a thin bottom wall at the lower end, and a thin vertical weakened portion 17 is formed at a position corresponding to the outer peripheral cutout 16 of the engaging protrusion 9 on the inner circumference of the outer peripheral wall 46.

外周壁部４６の背面側の外周切り込み部１６よりヒンジＣ側では、端面１６ａの内周側の上部の薄肉部を隔てた位置を起点として円周方向に延びて切り欠き凹部５０の右側の側面５０ｃまでと、さらに、切り欠き凹部５０の左側の側面５０ｃから外周切り込み部１６の近傍まで、スリット溝５１が上面４６ａから距離βで凹設され、また、外周壁部４６の外周切り込み部１６のヒンジＣと反対側の上面４６ａは、外周壁部４６上部と蓋係合部６下部とが一体に連結した肉厚部１９となっている。 On the hinge C side of the outer circumferential cutout 16 on the back side of the outer circumferential wall 46, a slit groove 51 is recessed at a distance β from the upper surface 46a, starting from a position separated by the thin portion of the upper inner circumferential side of the end face 16a and extending in the circumferential direction to the right side 50c of the cutout recess 50, and further from the left side 50c of the cutout recess 50 to the vicinity of the outer circumferential cutout 16. Also, the upper surface 46a of the outer circumferential cutout 16 of the outer circumferential wall 46 opposite the hinge C forms a thick portion 19 where the upper portion of the outer circumferential wall 46 and the lower portion of the lid engagement portion 6 are integrally connected.

外周壁部４６のスリット溝５１の底面５２の内側上部には、薄肉の横弱化部５３が形成され、また、外周壁部４６の背面側のスリット溝５１より外側部は、底面５２より上面４６ａまで上方に立設する背面外壁部５４となり、背面外壁部５４の外周上端の所定の位置にヒンジＣが連設される。 A thin-walled lateral weakened portion 53 is formed on the upper inside portion of the bottom surface 52 of the slit groove 51 of the outer peripheral wall portion 46, and the portion outside the slit groove 51 on the back side of the outer peripheral wall portion 46 becomes the back outer wall portion 54 which stands upward from the bottom surface 52 to the upper surface 46a, and a hinge C is connected to a predetermined position on the outer periphery upper end of the back outer wall portion 54.

外周壁部４６の内周上部は、横弱化部５３の高さより上部から内側上方に傾斜して、容器Ａに装着時に嵌合突条２の傾斜面２ａに当接する当接面部５５が形成されている。 The upper inner periphery of the outer wall 46 is inclined upward and inward from above the height of the lateral weakening portion 53, forming an abutment surface portion 55 that abuts against the inclined surface 2a of the mating protrusion 2 when attached to the container A.

蓋体Ｄａは、キャップ本体Ｂａの外周壁部４６の外周上端に、ヒンジＣを介して回動自在に取着されており、頂壁３０と、頂壁３０の周縁部から垂設される側周壁３１と、頂壁３０の裏面に垂設されて注出筒５を密封する密封筒３２とが設けられている。
側周壁３１の下面の注出側外周縁には、閉蓋時にキャップ本体Ｂａの外周壁部４６の切り欠き凹部５０の少なくとも外周面５０ａを内面が覆うように切り欠き凹部５０に係合する円弧状の被覆壁６０が垂設されている。 The lid body Da is attached to the upper outer end of the outer wall portion 46 of the cap body Ba via a hinge C so as to be freely rotatable, and is provided with a top wall 30, a side wall 31 extending vertically from the peripheral edge of the top wall 30, and a sealing tube 32 extending vertically from the back surface of the top wall 30 to seal the pouring tube 5.
An arc-shaped covering wall 60 is vertically attached to the pouring side outer edge of the lower surface of the side wall 31, and engages with the cutout recess 50 so that its inner surface covers at least the outer surface 50a of the cutout recess 50 in the outer wall portion 46 of the cap body Ba when the lid is closed.

次に、本実施例の使用態様と作用効果について説明する。
本実施例のヒンジキャップは、蓋体Ｄａの側周壁３１下面の注出側外周縁に被覆壁６０が設けられているので、閉蓋中にキャップ本体Ｂａの外周壁部４６の切り欠き凹部５０を隠し、また、開蓋の際には摘み部３８の下に掛けた手指がぶつかり、蓋体Ｄａの内方に接触することを防止しているので、キャップ内が清潔に保たれる。 Next, the manner of use and the effects of this embodiment will be described.
The hinge cap of this embodiment has a covering wall 60 provided on the pouring side outer edge of the underside of the side wall 31 of the lid body Da, which hides the cutout recess 50 in the outer wall portion 46 of the cap body Ba when the lid is closed, and prevents fingers hanging under the knob portion 38 from hitting and coming into contact with the inside of the lid body Da when the lid is opened, thereby keeping the inside of the cap clean.

本実施例のヒンジキャップは、キャップ本体Ｂａの外周壁部４６の注出側に緩く湾曲する湾曲面５０ｂを形成した切り欠き凹部５０を設けているので、内容液の使用中に容器Ａを傾けた方向の注出筒５のリップ部５ａから液が下の切り欠き凹部５０に垂れても、湾曲面５０ｂの傾斜により下に流れ落ち、また、湾曲面５０ｂが凹凸のない緩い湾曲面であるためティッシュ等で簡単に汚れを拭き取ることができる。 The hinge cap of this embodiment has a cutout recess 50 with a gently curved curved surface 50b on the pouring side of the outer wall 46 of the cap body Ba. Even if liquid drips from the lip 5a of the pouring tube 5 into the lower cutout recess 50 when the container A is tilted during use, the liquid will flow down due to the inclination of the curved surface 50b. Also, because the curved surface 50b is a gently curved surface with no unevenness, dirt can be easily wiped off with tissue or the like.

次に、容器Ａ内の内容液を全部使用した後、ヒンジキャップを分別廃棄する態様について説明する。
その際には、ヒンジキャップを開蓋し、蓋体Ｄａを指で把持して外方に引っ張ると、ヒンジＣを介して外周壁部４６のヒンジＣとの連設部となる背面外壁部５４が引っ張られ、連なる外周壁部４６の縦弱化部１７が破断すると、縦弱化部１７に連設する端面１６ａ側から横弱化部５３が周方向に切断され、外周壁部４６の横弱化部５３より下側がキャップ本体Ｂａから離されていく。
横弱化部５３が切り欠き凹部５０を通過し、肉厚部１９の手前まで切り裂かれると、破断が止められるとともに、連結している外周壁部４６の下部が外側に引っ張られ、キャップ本体Ｂａの外周壁部４６と容器Ａの口部１との嵌合が外され、そのまま上方に上げると、キャップ本体Ｂａが容器Ａの口部１から外されるので、ヒンジキャップと容器Ａとを分別廃棄することができる。
その他の作用効果については、第１実施例と同様である。 Next, a mode in which the hinge cap is separately disposed of after the liquid content in the container A has been completely used will be described.
In this case, when the hinge cap is opened and the lid body Da is grasped with the fingers and pulled outward, the back outer wall portion 54, which is the connecting portion of the outer wall portion 46 to the hinge C, is pulled via the hinge C, and when the connecting vertical weakened portion 17 of the outer wall portion 46 breaks, the horizontal weakened portion 53 is cut in the circumferential direction from the end face 16a side connected to the vertical weakened portion 17, and the part of the outer wall portion 46 below the horizontal weakened portion 53 is separated from the cap body Ba.
When the lateral weakened portion 53 passes through the cutout recess 50 and is torn up to just before the thick portion 19, the breakage is stopped and the lower portion of the connected outer peripheral wall portion 46 is pulled outward, disengaging the outer peripheral wall portion 46 of the cap body Ba from the mouth portion 1 of the container A. When the cap body Ba is then lifted upward, it is removed from the mouth portion 1 of the container A, and the hinge cap and container A can be disposed of separately.
The other functions and effects are similar to those of the first embodiment.

次に、上記第１実施例のキャップ本体Ｂおよび蓋体Ｄを変更した第３実施例について、図を参照して説明する。
以下、第１実施例と同一の構成部分には同一の符号を付し、変更部分に新たな符号を付し、相違点を中心に説明する。 Next, a third embodiment in which the cap body B and the lid body D of the first embodiment are modified will be described with reference to the drawings.
In the following, the same components as those in the first embodiment are given the same reference numerals, changed components are given new reference numerals, and differences will be mainly described.

図７において、Ａは容器、Ｂｂは容器Ａに装着されるキャップ本体、Ｄｂはキャップ本体ＢｂにヒンジＣを介して開閉可能に取り付けられる蓋体である。
キャップ本体Ｂｂは、図７および図８に示すように、容器Ａの口部１に装着される装着部６５と、装着部６５の内縁から内方に延設され、口部１の開口を封鎖する上壁４と、上壁４を貫通する注出口４ａと、注出口４ａから僅かに拡径した径で上壁４の上面に立設される注出筒５とを備えている。 In FIG. 7, A is a container, Bb is a cap body attached to the container A, and Db is a lid body attached to the cap body Bb via a hinge C so as to be openable and closable.
As shown in Figures 7 and 8, the cap body Bb comprises an attachment portion 65 that is attached to the mouth portion 1 of the container A, an upper wall 4 that extends inward from the inner edge of the attachment portion 65 and seals the opening of the mouth portion 1, a pouring outlet 4a that penetrates the upper wall 4, and a pouring tube 5 that is erected on the upper surface of the upper wall 4 with a diameter slightly wider than the pouring outlet 4a.

装着部６５は、蓋体Ｄｂと係合する環状の蓋係合部６と、蓋係合部６の内周側から垂設される内筒７と、蓋係合部６の外周に内周上部が連設される外周壁部６６とから構成されており、外周壁部６６には、背面側上端にヒンジＣが連設され、内周下部に容器Ａの口部１の嵌合突条２と係合する係合突部９が設けられている。 The mounting portion 65 is composed of an annular lid engaging portion 6 that engages with the lid body Db, an inner tube 7 that is suspended from the inner periphery of the lid engaging portion 6, and an outer peripheral wall portion 66 whose upper inner periphery is connected to the outer periphery of the lid engaging portion 6. A hinge C is connected to the upper end of the back side of the outer peripheral wall portion 66, and an engaging protrusion 9 is provided at the lower inner periphery that engages with the mating protrusion 2 of the mouth portion 1 of the container A.

外周壁部６６の上部には、注出側に、ほぼ１８０°の円弧範囲で円弧状に上から距離βの深さで外周から凹設された段凹部７０が設けられ、残りの背面側は、上面６６ａが上壁４上面および切り欠き部１０底面と面一の高さとなり、外周上端にヒンジＣが連設される。
段凹部７０は、上面６６ａから距離β下がった平坦面７０ａと、平坦面７０ａの端部の両側から上面６６ａのそれぞれの両側に向って傾斜する傾斜側面７０ｃとが形成されている。 At the upper part of the outer peripheral wall portion 66, on the pouring side, there is a stepped recess 70 recessed from the outer periphery in an arc shape over an arc range of approximately 180° to a depth of a distance β from above, and on the remaining back side, the upper surface 66a is flush with the upper surface of the upper wall 4 and the bottom surface of the cutout portion 10, and a hinge C is connected to the upper end of the outer periphery.
The stepped recess 70 is formed with a flat surface 70a that is recessed a distance β from the upper surface 66a, and inclined side surfaces 70c that are inclined from both sides of the end of the flat surface 70a toward both sides of the upper surface 66a.

外周壁部６６のヒンジＣの左近傍には、略Ｖ字状の外周切り込み部１６が切り込まれ、外周壁部６６内周の係合突部９の外周切り込み部１６に対応する位置には、薄肉となる縦弱化部１７が形成される。 A roughly V-shaped outer circumferential cut 16 is cut into the outer circumferential wall 66 near the left of the hinge C, and a thin vertical weakened portion 17 is formed at a position corresponding to the outer circumferential cut 16 of the engaging protrusion 9 on the inner periphery of the outer circumferential wall 66.

外周壁部６６の背面側では、端面１６ａの内周側の上部の薄肉部を隔てた位置を起点として円周方向に延びて段凹部７０の右端側の傾斜側面７０ｃまでと、さらに、段凹部７０の先の傾斜側面７０ｃから外周切り込み部１６の近傍まで、凹設されるとともに、底面７２が段凹部７０の平坦面７０ａと面一となる上面６６ａから距離βのスリット溝７１が形成され、また、外周壁部６６の外周切り込み部１６のヒンジＣと反対側の上面６６ａは、外周壁部６６上部と蓋係合部６下部とが一体に連結した肉厚部１９となっている。
また、外周壁部６６の背面側のスリット溝７１より外側部は、スリット溝７１の底面７２より上面６６ａまで上方に立設する背面外壁部７３となり、背面外壁部７３の外周上端の所定の位置にヒンジＣが連設される。 On the back side of the outer peripheral wall portion 66, a recess is formed starting from a position separated by the thin-walled portion at the upper part of the inner peripheral side of the end face 16a, extending circumferentially to the inclined side surface 70c on the right end side of the step recess 70, and further from the inclined side surface 70c at the end of the step recess 70 to the vicinity of the outer peripheral cut-out portion 16, and a slit groove 71 is formed at a distance β from the upper surface 66a whose bottom surface 72 is flush with the flat surface 70a of the step recess 70, and the upper surface 66a opposite the hinge C of the outer peripheral cut-out portion 16 of the outer peripheral wall portion 66 forms a thick-walled portion 19 where the upper part of the outer peripheral wall portion 66 and the lower part of the lid engagement portion 6 are integrally connected.
In addition, the outer portion of the outer peripheral wall portion 66 outside the slit groove 71 on the rear side becomes a rear outer wall portion 73 that extends upward from the bottom surface 72 of the slit groove 71 to the upper surface 66a, and a hinge C is connected to a predetermined position at the upper end of the outer periphery of the rear outer wall portion 73.

外周壁部６６は、端面１６ａ側からヒンジＣの中央部までスリット溝７１の底面７２の内周側上部が薄肉の横弱化部７４となり、スリット溝７１の底面７２のヒンジＣの中央部から段凹部７０の平坦面７０ａまで（ヒンジＣの中央から右側に向かって２７０°の円弧範囲）の連結する内周縁には、内側に向かい上方に傾斜する円弧状の連結部７５が設けられている。 The outer peripheral wall portion 66 has a thin-walled lateral weakening portion 74 at the upper inner peripheral side of the bottom surface 72 of the slit groove 71 from the end face 16a side to the center of the hinge C, and an arc-shaped connecting portion 75 that slopes upward and inward is provided on the inner peripheral edge that connects the center of the hinge C of the bottom surface 72 of the slit groove 71 to the flat surface 70a of the step recess 70 (a 270° arc range from the center of the hinge C to the right).

外周壁部６６の内周上部には、左側から背面側中央まで、横弱化部７４より上部から内側上方に傾斜して、容器Ａに装着時に嵌合突条２の傾斜面２ａに当接する当接面部７６が形成され、背面側中央から右側、注出側を通って左側までの間には、外側の連結部７５の外側面と平行に内側上方に傾斜するとともに容器Ａに装着時に嵌合突条２の傾斜面２ａから離れるように形成される平行面７７が設けられ、平行面７７と連結部７５外面との間は薄肉となって連結弱化部７８が形成されている。
また、横弱化部７４と連結弱化部７８とは、連続するように形成されている。 At the upper inner periphery of the outer wall portion 66, from the left side to the center of the back side, a contact surface portion 76 is formed which slopes inward and upward from above the lateral weakening portion 74 and abuts against the inclined surface 2a of the fitting protrusion 2 when attached to container A, and from the center of the back side to the right side, through the pouring side to the left side, a parallel surface 77 is provided which slopes inward and upward parallel to the outer surface of the outer connecting portion 75 and is formed so as to move away from the inclined surface 2a of the fitting protrusion 2 when attached to container A, and the portion between the parallel surface 77 and the outer surface of the connecting portion 75 is thin-walled to form a connection weakening portion 78.
Moreover, the lateral weakened portion 74 and the joint weakened portion 78 are formed so as to be continuous with each other.

蓋体Ｄｂは、側周壁３１の下面の注出側外周縁に、閉蓋時にキャップ本体Ｂｂの外周壁部６６の段凹部７０の平坦面７０ａおよび両側の傾斜側面７０ｃの外周縁に、下面が近接あるいは当接するように形成された円弧状の被覆壁８０が垂設されている。 The lid body Db has an arc-shaped covering wall 80 that is vertically attached to the outer peripheral edge of the pouring side of the lower surface of the side peripheral wall 31 so that when the lid is closed, the lower surface of the covering wall 80 is close to or abuts the outer peripheral edges of the flat surface 70a of the stepped recess 70 of the outer peripheral wall portion 66 of the cap body Bb and the inclined side surfaces 70c on both sides.

次に、本実施例の使用態様と作用効果について説明する。
本実施例のヒンジキャップは、蓋体Ｄｂの側周壁３１下面の注出側外周縁に被覆壁８０が設けられているので、閉蓋中にキャップ本体Ｂｂの外周壁部６６の段凹部７０を隠し、また、開蓋の際には摘み部３８の下に掛けた手指がぶつかり、蓋体Ｄｂの内方に接触することを防止しているので、キャップ内が清潔に保たれる。 Next, the manner of use and the effects of this embodiment will be described.
The hinge cap of this embodiment has a covering wall 80 provided on the pouring side outer edge of the underside of the side wall 31 of the lid body Db, which hides the step recess 70 of the outer wall portion 66 of the cap body Bb when the lid is closed, and prevents fingers placed under the knob portion 38 from hitting and coming into contact with the inside of the lid body Db when the lid is opened, thereby keeping the inside of the cap clean.

本実施例のヒンジキャップは、キャップ本体Ｂｂのキャップ本体Ｂｂの外周壁部６６の注出側に平坦面７０ａと連結部７５とを形成した段凹部７０を設けているので、内容液の使用中に容器Ａを傾けた方向の注出筒５のリップ部５ａから液が下の段凹部７０に垂れても、連結部７５の傾斜により平坦面７０ａに流れ、また、平坦面７０ａが凹凸のない平面であるためティッシュ等で簡単に汚れを拭き取ることができる。 The hinge cap of this embodiment has a stepped recess 70 formed with a flat surface 70a and a connecting portion 75 on the pouring side of the outer wall portion 66 of the cap body Bb. Even if liquid drips from the lip portion 5a of the pouring tube 5 into the lower stepped recess 70 when the container A is tilted during use, the liquid will flow to the flat surface 70a due to the inclination of the connecting portion 75. Also, since the flat surface 70a is a flat surface without any irregularities, dirt can be easily wiped off with tissue, etc.

次に、容器Ａ内の内容液を全部使用した後、ヒンジキャップを分別廃棄する態様について説明する。
その際には、ヒンジキャップを開蓋し、蓋体Ｄｂを指で把持して外方に引っ張ると、ヒンジＣを介して外周壁部６６のヒンジＣとの連設部となる背面外壁部７３が引っ張られ、連なる外周壁部６６の縦弱化部１７が破断すると、縦弱化部１７に連設する端面１６ａ側から横弱化部７４が周方向に切断され、外周壁部６６の横弱化部７４より下側がキャップ本体Ｂｂから離されていく。 Next, a mode in which the hinge cap is separately disposed of after the liquid content in the container A has been completely used will be described.
In this case, when the hinge cap is opened and the lid body Db is grasped with the fingers and pulled outward, the back outer wall portion 73, which is the connecting portion of the outer peripheral wall portion 66 to the hinge C, is pulled via the hinge C, and when the connecting vertical weakened portion 17 of the outer peripheral wall portion 66 breaks, the horizontal weakened portion 74 is cut in the circumferential direction from the end face 16a side connected to the vertical weakened portion 17, and the part of the outer peripheral wall portion 66 below the horizontal weakened portion 74 is separated from the cap body Bb.

次に、横弱化部７４が完全に破断すると、連続する連結弱化部７８がヒンジＣの中央から破断されていき、最後は、段凹部７０を通過して、肉厚部１９で止められる。
さらに、破断された外周壁部６６を引っ張ると、連結している外周壁部６６の肉厚部１９が外側に引っ張られ、キャップ本体Ｂｂの外周壁部６６の係合突部９と容器Ａの口部１の嵌合突条２との嵌合が外され、そのまま上方に上げると、肉厚部１９で連設されている外周壁部６６の上側およびその内方が持ち上げられキャップ本体Ｂｂが容器Ａの口部１から外されるので、ヒンジキャップと容器Ａとを分別廃棄することができる。 Next, when the lateral weakened portion 74 is completely broken, the continuous connecting weakened portion 78 is broken from the center of the hinge C, and finally passes through the step recess 70 and is stopped by the thick portion 19.
Furthermore, when the broken outer wall portion 66 is pulled, the thick portion 19 of the connected outer wall portion 66 is pulled outward, disengaging the engaging protrusion 9 of the outer wall portion 66 of the cap body Bb from the engaging protrusion 2 of the mouth portion 1 of the container A, and when it is raised in this state, the upper side and its inner side of the outer wall portion 66 connected by the thick portion 19 are lifted and the cap body Bb is removed from the mouth portion 1 of the container A, so that the hinge cap and container A can be disposed of separately.

本実施例のヒンジキャップは、連結弱化部７８を切断する際に、連結弱化部７８を形成する内周の平行面７７が容器Ａの嵌合突条２の傾斜面２ａより離れていくので、切断する抵抗が少なくなり、破断し易くなっている。
その他の作用効果については、第１実施例と同様である。 In the hinge cap of this embodiment, when the connection weakening portion 78 is cut, the inner parallel surface 77 forming the connection weakening portion 78 moves away from the inclined surface 2a of the mating protrusion 2 of the container A, so that there is less resistance to cutting and the hinge cap is easier to break.
The other functions and effects are similar to those of the first embodiment.

次に、上記第１実施例のキャップ本体Ｂおよび蓋体Ｄを変更した第４実施例について、図を参照して説明する。
以下、第１実施例と同一の構成部分には同一の符号を付し、変更部分に新たな符号を付し、相違点を中心に説明する。 Next, a fourth embodiment in which the cap body B and the lid body D of the first embodiment are modified will be described with reference to the drawings.
In the following, the same components as those in the first embodiment are given the same reference numerals, changed components are given new reference numerals, and differences will be mainly described.

図９において、Ａは容器、Ｂｃは容器Ａに装着されるキャップ本体、Ｄｃはキャップ本体ＢｃにヒンジＣを介して開閉可能に取り付けられる蓋体である。
キャップ本体Ｂｃは、図９および図１０に示すように、容器Ａの口部１に装着される装着部８５と、装着部８５の内縁から内方に延設され、口部１の開口を封鎖する上壁４と、上壁４を貫通する注出口４ａと、注出口４ａから僅かに拡径した径で上壁４の上面に立設される注出筒５とを備えている。 In FIG. 9, A is a container, Bc is a cap body attached to the container A, and Dc is a lid body attached to the cap body Bc via a hinge C so as to be openable and closable.
As shown in Figures 9 and 10, the cap body Bc comprises an attachment portion 85 that is attached to the mouth portion 1 of the container A, an upper wall 4 that extends inward from the inner edge of the attachment portion 85 and seals the opening of the mouth portion 1, a pouring outlet 4a that penetrates the upper wall 4, and a pouring tube 5 that is erected on the upper surface of the upper wall 4 with a diameter slightly wider than the pouring outlet 4a.

装着部８５は、蓋体Ｄｃと係合する環状の蓋係合部６と、蓋係合部６の内周側から垂設される内筒７と、蓋係合部６の外周に内周上部が連設される外周壁部８６とから構成されており、外周壁部８６には、背面側上端にヒンジＣが連設され、内周下部に容器Ａの口部１の嵌合突条２と係合する係合突部９が設けられている。 The mounting portion 85 is composed of an annular lid engagement portion 6 that engages with the lid body Dc, an inner tube 7 that is suspended from the inner periphery of the lid engagement portion 6, and an outer peripheral wall portion 86 whose upper inner periphery is connected to the outer periphery of the lid engagement portion 6. A hinge C is connected to the upper end of the rear side of the outer peripheral wall portion 86, and an engagement protrusion 9 is provided at the lower inner periphery that engages with the mating protrusion 2 of the mouth portion 1 of the container A.

外周壁部８６の上部には、注出側に、ほぼ１８０°の円弧範囲で円弧状に上から距離αの深さで外周から凹設された段凹部９０が設けられ、残りの背面側は、上面８６ａが上壁４上面および切り欠き部１０底面と面一の高さとなり、外周上端にヒンジＣが連設される。
段凹部９０は、上面８６ａから距離α下がった平坦面９０ａと、平坦面９０ａの端部の両側から上面８６ａのそれぞれの両側に向って傾斜する傾斜側面９０ｃとが形成されている。 At the upper part of the outer peripheral wall portion 86, on the pouring side, there is a stepped recess 90 recessed from the outer periphery in an arc shape over a circular range of approximately 180° to a depth of a distance α from above, and on the remaining back side, the upper surface 86a is flush with the upper surface of the upper wall 4 and the bottom surface of the cutout portion 10, and a hinge C is connected to the upper end of the outer periphery.
The stepped recess 90 is formed with a flat surface 90a that is recessed a distance α from the top surface 86a, and inclined side surfaces 90c that are inclined from both sides of the end of the flat surface 90a toward both sides of the top surface 86a.

外周壁部８６のヒンジＣの左近傍には、略Ｖ字状の外周切り込み部１６が切り込まれ、外周壁部８６内周の係合突部９の外周切り込み部１６に対応する位置には、薄肉となる縦弱化部１７が形成される。 A roughly V-shaped outer circumferential cut 16 is cut into the outer circumferential wall 86 near the left of the hinge C, and a thin vertical weakened portion 17 is formed at a position corresponding to the outer circumferential cut 16 of the engaging protrusion 9 on the inner periphery of the outer circumferential wall 86.

外周壁部８６の背面側では、端面１６ａの内周側の上部の薄肉部を隔てた位置を起点として円周方向に延びて段凹部９０の右端側の傾斜側面９０ｃまでと、さらに、段凹部９０の先の傾斜側面９０ｃから外周切り込み部１６の近傍まで、凹設されるとともに、底面９２が段凹部９０の平坦面９０ａと面一となる上面８６ａから距離αのスリット溝９１が形成され、また、外周壁部８６の外周切り込み部１６のヒンジＣと反対側の上面８６ａは、外周壁部８６上部と蓋係合部６下部とが一体に連結した肉厚部１９となっている。
また、外周壁部８６の背面側のスリット溝９１より外側部は、スリット溝９１の底面９２より上面８６ａまで上方に立設する背面外壁部９３となり、背面外壁部９３の外周上端の所定の位置にヒンジＣが連設される。 On the back side of the outer peripheral wall portion 86, a recess is formed starting from a position separated by the thin-walled portion at the upper part of the inner peripheral side of the end face 16a, extending circumferentially to the inclined side surface 90c on the right end side of the step recess 90, and further from the inclined side surface 90c at the end of the step recess 90 to the vicinity of the outer peripheral cut-out portion 16, and a slit groove 91 is formed at a distance α from the upper surface 86a, whose bottom surface 92 is flush with the flat surface 90a of the step recess 90, and the upper surface 86a opposite the hinge C of the outer peripheral cut-out portion 16 of the outer peripheral wall portion 86 forms a thick-walled portion 19 where the upper part of the outer peripheral wall portion 86 and the lower part of the lid engagement portion 6 are integrally connected.
In addition, the portion of the outer peripheral wall portion 86 outer than the slit groove 91 on the rear side constitutes a rear outer wall portion 93 that extends upward from the bottom surface 92 of the slit groove 91 to the upper surface 86a, and a hinge C is connected to a predetermined position at the upper end of the outer periphery of the rear outer wall portion 93.

外周壁部８６は、端面１６ａ側からヒンジＣの中央部までスリット溝９１の底面９２の内周側上部が薄肉の横弱化部９４となり、スリット溝９１の底面９２のヒンジＣの中央部から段凹部９０の平坦面９０ａまで（ヒンジＣの中央から右側に向かって２７０°の円弧範囲）の連結する内周縁には、内側に向かって上面８６ａの高さまで上方に傾斜する円弧状の連結部９５が設けられている。 The outer peripheral wall portion 86 has a thin-walled lateral weakening portion 94 at the upper inner peripheral side of the bottom surface 92 of the slit groove 91 from the end face 16a side to the center of the hinge C, and the inner peripheral edge connecting the center of the hinge C of the bottom surface 92 of the slit groove 91 to the flat surface 90a of the step recess 90 (a 270° arc range from the center of the hinge C to the right) has an arc-shaped connecting portion 95 that slopes inward and upward to the height of the upper surface 86a.

外周壁部８６の内周上部には、蓋係合部６の下面外周縁に上向き凹部９６が凹設され、上向き凹部９６の内面と連結部９５の外面との間は薄肉となって連結弱化部９７が形成される。
また、横弱化部９４と連結弱化部９７とは、順に連続するように形成されている。 An upward recess 96 is formed on the upper inner periphery of the outer wall portion 86, on the outer peripheral edge of the lower surface of the lid engagement portion 6, and the area between the inner surface of the upward recess 96 and the outer surface of the connecting portion 95 is thinned to form a connection weakening portion 97.
The lateral weakened portion 94 and the joint weakened portion 97 are formed so as to be continuous with each other.

蓋体Ｄｃは、側周壁３１の下面の注出側外周縁に、閉蓋時にキャップ本体Ｂｃの外周壁部８６の段凹部９０の平坦面９０ａおよび両側の傾斜側面９０ｃの外周縁に、下面が近接あるいは当接するように形成された円弧状の被覆壁１００が垂設されている。 The lid body Dc has an arc-shaped covering wall 100 that is vertically attached to the outer peripheral edge of the pouring side of the lower surface of the side peripheral wall 31 so that when the lid is closed, the lower surface of the covering wall 100 is close to or abuts the flat surface 90a of the stepped recess 90 of the outer peripheral wall portion 86 of the cap body Bc and the outer peripheral edges of the inclined side surfaces 90c on both sides.

次に、本実施例の使用態様と作用効果について説明する。
本実施例のヒンジキャップは、蓋体Ｄｃの側周壁３１下面の注出側外周縁に被覆壁１００が設けられているので、閉蓋中にキャップ本体Ｂｃの外周壁部８６の段凹部９０を隠し、また、開蓋の際には摘み部３８の下に掛けた手指がぶつかり、蓋体Ｄｃの内方に接触することを防止しているので、キャップ内が清潔に保たれる。 Next, the manner of use and the effects of this embodiment will be described.
The hinge cap of this embodiment has a covering wall 100 provided on the pouring side outer edge of the underside of the side wall 31 of the lid body Dc, which hides the step recess 90 in the outer wall portion 86 of the cap body Bc when the lid is closed.In addition, when the lid is opened, fingers placed under the knob portion 38 are prevented from hitting and coming into contact with the inside of the lid body Dc, thereby keeping the inside of the cap clean.

本実施例のヒンジキャップは、キャップ本体Ｂｃのキャップ本体Ｂｃの外周壁部８６の注出側に平坦面９０ａと連結部９５とを形成した段凹部９０を設けているので、内容液の使用中に容器Ａを傾けた方向の注出筒５のリップ部５ａから液が下の段凹部９０に垂れても、連結部９５の傾斜により平坦面９０ａに流れ、また、平坦面９０ａが凹凸のない平面であるためティッシュ等で簡単に汚れを拭き取ることができる。 The hinge cap of this embodiment has a stepped recess 90 formed with a flat surface 90a and a connecting portion 95 on the pouring side of the outer wall portion 86 of the cap body Bc. Even if liquid drips from the lip portion 5a of the pouring tube 5 into the lower stepped recess 90 when the container A is tilted during use, the liquid will flow to the flat surface 90a due to the inclination of the connecting portion 95. Also, since the flat surface 90a is a flat surface without any irregularities, dirt can be easily wiped off with tissue, etc.

次に、容器Ａ内の内容液を全部使用した後、ヒンジキャップを分別廃棄する態様について説明する。
その際には、ヒンジキャップを開蓋し、蓋体Ｄｃを指で把持して外方に引っ張ると、ヒンジＣを介して外周壁部８６のヒンジＣとの連設部となる背面外壁部９３が引っ張られ、連なる外周壁部８６の縦弱化部１７が破断すると、縦弱化部１７に連設する端面１６ａ側から横弱化部９４が周方向に切断され、外周壁部８６の横弱化部９４より下側がキャップ本体Ｂｃから離されていく。 Next, a mode in which the hinge cap is separately disposed of after the liquid content in the container A has been completely used will be described.
In this case, when the hinge cap is opened and the lid body Dc is grasped with the fingers and pulled outward, the back outer wall portion 93, which is the connecting portion of the outer peripheral wall portion 86 to the hinge C, is pulled via the hinge C, and when the connecting vertical weakened portion 17 of the outer peripheral wall portion 86 breaks, the horizontal weakened portion 94 is cut in the circumferential direction from the end face 16a side connected to the vertical weakened portion 17, and the part of the outer peripheral wall portion 86 below the horizontal weakened portion 94 is separated from the cap body Bc.

次に、横弱化部９４が完全に破断すると、連続する連結弱化部９７がヒンジＣの中央から破断されていき、最後は、段凹部９０を通過して、肉厚部１９で止められる。
さらに、破断された外周壁部８６を引っ張ると、連結している外周壁部８６の肉厚部１９が外側に引っ張られ、キャップ本体Ｂｃの外周壁部８６の係合突部９と容器Ａの口部１の嵌合突条２との嵌合が外され、そのまま上方に上げると、肉厚部１９で連設されている外周壁部８６の上側およびその内方が持ち上げられキャップ本体Ｂｃが容器Ａの口部１から外されるので、ヒンジキャップと容器Ａとを分別廃棄することができる。 Next, when the lateral weakened portion 94 is completely broken, the continuous connecting weakened portion 97 is broken from the center of the hinge C, and finally passes through the step recess 90 and is stopped by the thick portion 19.
Furthermore, when the broken outer wall portion 86 is pulled, the thick portion 19 of the connected outer wall portion 86 is pulled outward, disengaging the engaging protrusion 9 of the outer wall portion 86 of the cap body Bc from the mating protrusion 2 of the mouth portion 1 of the container A, and when it is raised in this state upward, the upper side and its inner side of the outer wall portion 86 connected by the thick portion 19 are lifted and the cap body Bc is removed from the mouth portion 1 of the container A, so that the hinge cap and container A can be disposed of separately.

本実施例のヒンジキャップは、連結弱化部９７を切断する際に、該部分の内周面の上向き凹部９６が容器Ａの嵌合突条２の傾斜面２ａから完全に離れているので、切断する抵抗が少なくなり、破断し易くなっている。
その他の作用効果については、第１実施例と同様である。 In the hinge cap of this embodiment, when the weakened connection portion 97 is cut, the upward recess 96 on the inner surface of said portion is completely separated from the inclined surface 2a of the mating protrusion 2 of the container A, so there is less resistance to cutting and the hinge cap is easier to break.
The other functions and effects are similar to those of the first embodiment.

本発明のヒンジキャップは、内容液の注出時に、液がキャップ本体の注出側に垂れても、垂れた液を簡単に拭き取ることができるとともに、容器の廃棄時に、容器から簡単に分別できるので、食品等を収納する容器のヒンジキャップとして好適である。 The hinge cap of the present invention is suitable as a hinge cap for containers that store food, etc., because even if the liquid drips onto the pouring side of the cap body when pouring the contents, the dripping liquid can be easily wiped off, and it can be easily separated from the container when the container is disposed of.
