Description

【０００１】
【産業上の利用分野】
本発明は横断面が非円形の棒状化粧料を収容する繰出容器に関するものである。
【０００２】
【従来の技術】
横断面が非円形、例えば楕円形をなす棒状化粧料を収容する棒状化粧料繰出容器には、外筒とその内部を昇降する皿部が棒状化粧料と同様に横断面楕円形に形成されていて、外筒の下部内側には操作部材が回動可能に取り付けられ、外筒の下部に設けた窓孔から前記操作部材を回動操作できるようになっていて、皿部と操作部材との間に操作部材の回転運動を皿部の直線運動に変換する変換機構が設けられたものがある。この場合、外筒に嵌脱自在な蓋筒も横断面が楕円形である。
【０００３】
【発明が解決しようとする課題】
ところで、棒状化粧料には揮発性成分を含むものがあり、このような棒状化粧料を収容する繰出容器では気密機構が必要である。しかしながら、横断面非円形をなす棒状化粧料の場合には、前述のように外筒、皿部、蓋筒がいずれも横断面非円形であり、その非円形の摺動部分を気密状態に保持するのは極めて困難であった。
【０００４】
本発明はこのような従来の技術の問題点に鑑みてなされたものであり、横断面非円形の棒状化粧料を収容する繰出容器において、簡単な構造で気密性に優れた棒状化粧料繰出容器を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明は前記課題を解決するために、以下の手段を採用した。
（本発明の要旨）
本発明は、横断面非円形の棒状化粧料と横断面が相似形をなし基部側に窓孔を備えた外筒と、前記棒状化粧料の基部を内嵌し前記外筒の内部に配されて外筒に対して軸線方向に移動可能で周方向に回転不能に取り付けられた皿部と、前記外筒の窓孔から操作環部を露出させて外筒に周方向へ回転可能で軸線方向へ移動不能に取り付けられた操作部材と、前記皿部と操作部材との間に設けられていて操作部材の回転運動を皿部の直線運動に変換する変換機構と、前記外筒の先部側に嵌脱自在な蓋筒とを備えた棒状化粧料繰出容器において、
前記外筒に、前記皿部の移動域よりも基部側に外筒の内周面に連なる円環壁部を設け、
前記操作部に、前記円環壁部でシール状態に圧接摺動可能なシール環部を有する有底円筒状のシール筒部を設け、
前記円環壁部及びシール筒部の内側に前記変換機構を設置し、
前記蓋筒の頂部内側に、該蓋筒を外筒に嵌着した時に外筒と蓋筒との間をシールするシール部材を配設してなり、
前記シール部材は、非嵌着時には蓋筒の内周面から離間して位置しているが、嵌着時に外筒の外周面に圧接し且つ外方に弾性変形せしめられて蓋筒の内周面に圧接する弾性筒部を備えることを特徴とする棒状化粧料繰出容器である（請求項１に対応）。
【０００６】
横断面非円形とは真円以外の形状のことであり、例えば、長方形や正方形等の四角形、あるいは楕円形等である。
前記外筒の円環壁部と前記操作部材のシール筒部の位置関係は、円環壁部をシール筒部の外側あるいは内側のいずれに配しても構わない。
【０００７】
前記皿部と操作部材との間に設ける変換機構としては螺子機構を例示することができる。
シール部材は蓋筒から脱落しないように取り付けられていればよく、その取付構造には特に限定はない。
【０００９】
（２）本発明は前記(１)に記載の棒状化化粧料繰出容器において、前記シール部材には前記弾性筒部よりも蓋筒の頂部側に空気抜き孔が形成されていることを特徴とする棒状化粧料繰出容器である（請求項２に対応）。このようにすると、蓋筒の嵌着時に内部が高圧化するのを防止することができ、蓋筒を確実且つスムーズに嵌着せしめることができる。さらに、（３）前記シール部材に、弾性筒部の上部に位置して蓋筒の環状突起に挿入される小径部を設け、該小径部に、該環状突起に挿入する際にその環状突起に設けられた縦突条間に挿入されて位置決めする縦突条を形成する（請求項３に対応）。
【００１０】
〈本発明の原材料〉
本発明における各構成に材料の限定はないが、その全てをプラスチックで形成することも可能である。
【００１１】
【作用】
〈本発明の作用〉
外筒の窓孔から露出する操作環部を操作して操作部材を回転すると、操作部材の回転運動が変換機構によって皿部の直線運動に変換され、皿部は外筒内を軸線方向に沿って移動する。
【００１２】
円環壁部とシール筒部によって外筒と操作部材との間がシールされており、蓋筒の嵌着時にはシール部材によって外筒と蓋筒との間がシールされるので、閉蓋時に棒状化粧料は外筒と操作部材と蓋筒とで囲まれた密閉空間内に格納されることとなる。したがって、棒状化粧料が揮発性成分を含むものであっても、揮発性成分の揮発を阻止することができる。
【００１３】
又、横断面が非円形の摺動部についてはシール構造を施す必要がなく、構造が簡単になる。
【００１４】
【実施例】
以下、本発明の実施例を図１から図７の図面に基いて説明する。
〈第１実施例〉
図１及び図２は本発明の第１実施例における棒状化粧料繰出容器の縦断面図であり、図４、図５は蓋筒を取り外した状態の平面図及び正面図である。
【００１５】
棒状化粧料繰出容器は、外筒１０と、ホルダ３０と、操作部材５０と、蓋筒７０とを備えている。
外筒１０はポリプロピレン製で、横断面が棒状化粧料（図示せず）と相似形の楕円形をなし、下から順に大径部１１，中径部１２，小径部１３になっていて上にいくにしたがって横断面寸法が小さくなっている。尚、図１は外筒１１の長軸方向に沿う縦断面図であり、図２は短軸方向に沿う縦断面図である。
【００１６】
外筒１０は大径部１１の底部に嵌着固定された底蓋１４によって閉塞されている。大径部１１には短軸方向に対向する部位に一対の窓孔１５が開口している。
中径部１２の外周面には、長軸方向に対向する部位に一対の縦条の係合突起１６が設けられており、短軸方向に対向する部位に一対の横長の係合突起１７が設けられている。
【００１７】
外筒１０の内周面であって中径部１２と小径部１３の境界部からは仕切り壁部１８が内方へ水平に延びている。仕切り壁部１８の中央には貫通孔が形成されており、仕切り壁部１８の下面からは前記貫通孔と同心状に円環壁部１９が下方に延びている。
【００１８】
小径部１３の内周面には長軸方向に対向する部位に一対の縦条の案内突起２０が設けられている。
【００１９】
操作部材５０は外筒１０の大径部１１及び中径部１２の内部に取り付けられており、操作部材５０は、内筒部５１と、外筒部（シール筒部）５２と、操作環部５３とを備えている。
【００２０】
内筒部５１はポリアセタール樹脂製で、中空円筒状をなし、前記外筒１０の仕切り壁部１８の貫通孔を貫通して、仕切り壁部１８に回動可能で且つ上下動不能に係合している。内筒部５１の上部内周面には、後述するホルダ３０の螺筒３２の螺溝３５に係合する一対の係合突起５４が内向きに設けられている。
【００２１】
この内筒部５１の外側に外筒部５２が固定されている。外筒部５２は低密度ポリエチレン製で、有底円筒状をなし、その底部を底蓋１４の環状突部２１の内側に回動可能に挿入し、外筒部５２の内部に前記内筒部５１を嵌着固定している。
【００２２】
外筒部５２の上部はシール環部５５になっていて、シール環部５５はその全周を外筒１０の円環壁部１９の内周面に圧接させ、シール状態に密接摺動するようになっている。
【００２３】
外筒部５２は外方に張り出す環体部５６を有しており、この環体部５６の外側に操作環部５３が嵌合固定されている。操作環部５３はポリプロピレン製で、その外周面の一部を外筒１０の窓孔１５に挿入して若干外方に突出させている。操作環部５３の外周面には滑り止め用の縦突条が多数平行に形成されている。
【００２４】
以上のように、操作部材５０は外筒１０に上下方向に移動不能に取り付けられており、窓孔１５から露出する操作環部５３を操作することによって回動することができるようになっている。
【００２５】
ホルダ３０はポリプロピレン製で、、外筒１０の小径部１３内に収納された有底の皿部３１と、この皿部３１の底面中央から下方に延びる螺筒３２とから構成されている。
【００２６】
皿部３１は横断面を棒状化粧料と相似形の楕円形に形成されていて、棒状化粧料の基部を内嵌させてこれを支持している。皿部３１の外周面には前記外筒１０の案内突起２０に係合する縦溝３３が設けられている。又、皿部３１の上部外周縁には外筒１０の小径部１３の内周面にほぼ当接する鍔３４が周設されている。
【００２７】
一方、ホルダ３０の螺筒３２は円筒状をなし、その外周面には螺溝３５が螺旋状に形成されている。この螺溝３５には前記操作部材５０の係合突起５４が係合しており、これによって、操作部材５０を回動するとホルダ３０が小径部１３内を上下動し、棒状化粧料が外筒１０から突没するようになっている。即ち、この実施例では、ホルダ３０の螺溝３５と操作部材５０の係合突起５４によって、変換機構が構成されている。
【００２８】
蓋筒７０はポリプロピレン製で、横断面を外筒１０と相似形の楕円形に形成されていて、嵌着時には下部が外筒１０の中径部１２に外嵌し、下縁が大径部１１の上縁に突き当たるようになっている。又、蓋筒７０の内周面下部には、嵌着時に前記外筒１０の係合突起１６が係合する縦溝７１と、嵌着時に外筒１０の係合突起１７が係合する横溝７２が設けられている。
【００２９】
蓋筒７０の頂部には横断面が楕円形の環状突起７３が形成されている。環状突起７３の内周面には、長軸方向及び短軸方向に対向する部位に、互いに平行に配された各一対の縦突条が形成されている。
【００３０】
この環状突起７３の内側にはシール部材８０が取り付けられている。シール部材８０は低密度ポリエチレン製で弾性を有し、横断面が楕円形の有頂筒状をなし、上部が小径部８１、下部が大径部（弾性筒部）８２になっている。小径部８１の外周面には、長軸方向及び短軸方向に対向する部位に、各１本の縦突条が形成されている。
【００３１】
小径部８１は環状突起７３内に挿入されており、挿入の際に小径部８１の縦突条を環状突起７３の縦突条間に挿入することによって位置決めされる。そして、小径部８１の天板部を両面貼着テープ９０によって蓋筒７０の頂部に貼着固定することにより、シール部材８０は蓋筒７０に固定されている。
【００３２】
大径部８２は下方に末広がりな形状をなし、その内周面の途中には内方に膨出する環状の膨出部８３が設けられ、外周面の下縁には外方へ突出する環状のシール突部８４が設けられている。
【００３３】
図３において二点鎖線で示すように、蓋筒７０の非嵌着時において、膨出部８３の内面はその全周を外筒１０の小径部１３の先部外周面よりも若干小さく形成されており、シール突部８４の外周面はその全周を蓋筒７０の周壁部内周面よりも若干小さく形成されている。
【００３４】
そして、蓋筒７０を外筒１０に嵌着した時に、外筒１０の小径部１３が膨出部８３を外方に押し広げながら膨出部８３の内側に嵌入し、その結果、外径部８２の先部も外方へ押し広げられて、シール突部８４の外周面の全周が蓋筒７０の周壁部内周面に圧接するようになっている。
【００３５】
即ち、シール部材８０の大径部８２は蓋筒７０の嵌着時に外筒１０の小径部１３と蓋筒７０の周壁部との間に挟装されるとともに弾性変形せしめられるようになっていて、その弾性復元力によって、膨出部８３が全周的に外筒１０の小径部１３の外周面を強く圧接してこの間をシールし、シール突部８４が全周的に蓋筒７０の内周面を強く圧接してこの間をシールするようになっている。
【００３６】
又、シール部材８０には、小径部８１と大径部８２との間の段差部８５において短軸方向に対向する部位に、空気抜き孔８６が形成されている。この空気抜き孔８６は、蓋筒７０の嵌着操作時にシール部材８０内で加圧された空気圧を外部に逃がすためのものである。
【００３７】
即ち、シール部材８０の内部は空気抜き孔８６を介して蓋筒７０とシール部材８０との間の空間８７に連通しており、空間８７内の圧力が上昇すると、その圧力によってシール部材８０の大径部８２の先部が内方に弾性変形してシール突部８４と蓋筒７０の周壁部内周面との間に隙間ができ、この隙間から圧力を逃がすのである。空気圧が逃げて空間８７内の圧力が低下すると、大径部８２の先部が再び広がってシール突部８４が蓋筒７０の周壁部内周面に圧接してシールする。
【００３８】
上述構成の棒状化粧料繰出容器においては、操作部材５０の外筒部５２が有底筒状であり、外筒１０の円環壁部１９と操作部材５０のシール環部５５とがシール状態に摺動し、外筒部５２及びシール環部５５と円環壁部１９の内側に変換機構を収容し、蓋筒７０の嵌着時に外筒１０と蓋筒７０との間をシール部材８０の大径部８２によってシールしているので、棒状化粧料は外筒１０と操作部材５０とシール部材８０と蓋筒７０によって囲まれた密閉空間内に収納されることとなる。したがって、棒状化粧料が揮発性成分を含むものであっても、揮発性成分の揮発を阻止することができる。
【００３９】
そして、摺動部（即ち円環壁部１９とシール環部５５の摺動部）におけるシール部分を円環状としたので、構造が簡単で、成形性がよく、しかもシール性のよいものにすることができる。又、完全なシール構造にするのが困難な楕円状の摺動部（即ち、皿部３１と外筒１０の小径部１３との間）については、シール構造にする必要がなくなる。
【００４０】
〈第２実施例〉
図６及び図７は本発明の第２実施例における棒状化粧料繰出容器の要部縦断面図であり、図６は短軸方向に沿った断面を示し、図７は長軸方向に沿った断面を示している。
【００４１】
第２実施例の第１実施例との相違点は、シール部材８０の取付構造と、空気抜き孔８６の設置位置にある。
即ち、第２実施例における蓋筒７０の頂部は凸曲面状に膨出していて、シール部材８０の天板部との間に空間が形成されている。そのため、両面貼着テープ９０によってシール部材８０を蓋筒７０に貼着する代わりに、シール部材８０の小径部８１の天板部に起立壁部８８を設け、この起立壁部８８を蓋筒７０の頂部に突き当て、小径部８１の外周面に外方へ突出する係合突起８９を設け、この係合突起８９を蓋筒７０の上部内周面に設けた係合溝７４に係合することによって、シール部材８０を上下動不能に固定している。尚、シール部材８０の周方向の位置決め構造は第１実施例の場合と同様であり、それによってシール部材８０は回動不能に固定される。尚、空気抜き孔８６は小径部８１に設けられている。そのほかの点は、第１実施例のものと同じである。
【００４２】
【発明の効果】
以上説明したように、本発明によれば、蓋筒を外筒に嵌着した時に、横断面非円形の棒状化粧料を、外筒と操作部材と蓋筒によって囲まれた密閉空間内に格納することができ、棒状化粧料から揮発性成分が揮発するのを確実に防止することができるという優れた効果が奏される。しかも、非円形の摺動部にはシール構造を施す必要がないので、構造が簡単である。
【００４３】
シール部材に弾性筒部を設けた場合には、シール性が非常によい。
シール部材に空気抜き孔を設けると、蓋筒の嵌着を確実に且つスムーズに行うことができる。

[0002]
[Prior art]
In a bar-shaped cosmetic supply container for storing a bar-shaped cosmetic material having a non-circular cross-section, for example, an elliptical shape, an outer cylinder and a plate portion for raising and lowering the inside thereof are formed in an elliptical cross-sectional shape in the same manner as the bar-shaped cosmetic material. An operating member is pivotably attached to the lower inner side of the outer cylinder, and the operating member can be rotated from a window hole provided in the lower part of the outer cylinder. Some have a conversion mechanism for converting the rotational movement of the operation member into the linear movement of the plate. In this case, the cross-section of the cover cylinder that can be freely inserted into and removed from the outer cylinder is also elliptic.
[0003]
[Problems to be solved by the invention]
By the way, some stick-shaped cosmetics contain a volatile component, and an airtight mechanism is required in a feeding container for storing such stick-shaped cosmetics. However, in the case of a bar-shaped cosmetic material having a non-circular cross-section, as described above, the outer cylinder, the dish part, and the cover cylinder are all non-circular in cross-section, and the non-circular sliding portion is kept airtight. It was extremely difficult to do.
[0004]
The present invention has been made in view of the above-described problems of the prior art, and is a dispensing container for storing a non-circular cross-sectionally shaped bar-shaped cosmetic, and has a simple structure and excellent airtightness. The purpose is to provide.

[0006]
The non-circular cross-section means a shape other than a perfect circle, for example, a rectangle such as a rectangle or a square, or an ellipse.
Regarding the positional relationship between the annular wall portion of the outer cylinder and the seal cylinder portion of the operation member, the annular wall portion may be arranged either on the outside or the inside of the seal cylinder portion.
[0007]
An example of the conversion mechanism provided between the dish portion and the operation member is a screw mechanism.
The seal member only needs to be attached so as not to drop off from the lid cylinder, and the attachment structure is not particularly limited.
[0009]

This is a stick-shaped cosmetic material supply container (corresponding to claim 2). If it does in this way, it can prevent that an inside becomes high voltage | pressure at the time of the fitting of a cover cylinder, and can fit a cover cylinder reliably and smoothly. Further, (3) the seal member is provided with a small-diameter portion that is positioned above the elastic cylinder portion and is inserted into the annular projection of the lid cylinder, and the small-diameter portion is provided with the annular projection when inserted into the annular projection. A vertical ridge inserted between the provided vertical ridges for positioning is formed (corresponding to claim 3).
[0010]
<Raw material of the present invention>
There is no limitation on the material of each component in the present invention, but it is also possible to form all of them with plastic.
[0011]

The space between the outer cylinder and the operating member is sealed by the annular wall part and the sealing cylinder part, and when the cover cylinder is fitted, the space between the outer cylinder and the cover cylinder is sealed by the seal member. The cosmetic is stored in a sealed space surrounded by the outer cylinder, the operation member, and the lid cylinder. Therefore, even if the stick-shaped cosmetic contains a volatile component, the volatilization of the volatile component can be prevented.
[0013]
Further, the sliding portion having a non-circular cross section does not need to be provided with a seal structure, and the structure is simplified.

On the other hand, the screw cylinder 32 of the holder 30 has a cylindrical shape, and a screw groove 35 is formed in a spiral shape on the outer peripheral surface thereof. Engaging protrusions 54 of the operating member 50 are engaged with the screw grooves 35, so that when the operating member 50 is rotated, the holder 30 moves up and down in the small-diameter portion 13, and the bar-shaped cosmetic material is moved to the outer cylinder. It starts to sink from 10. That is, in this embodiment, the conversion mechanism is configured by the screw groove 35 of the holder 30 and the engagement protrusion 54 of the operation member 50.
[0028]
The cover cylinder 70 is made of polypropylene and has a cross section formed in an elliptical shape similar to that of the outer cylinder 10. When fitted, the lower part is externally fitted to the middle diameter part 12 of the outer cylinder 10, and the lower edge is the large diameter part. 11 is hitting the upper edge. Further, in the lower part of the inner peripheral surface of the lid cylinder 70, a vertical groove 71 that engages with the engaging protrusion 16 of the outer cylinder 10 when fitted, and a horizontal groove that engages with the engaging protrusion 17 of the outer cylinder 10 when fitted. 72 is provided.
[0029]
An annular projection 73 having an elliptical cross section is formed on the top of the lid cylinder 70. On the inner peripheral surface of the annular protrusion 73, a pair of vertical protrusions are formed in parallel to each other at portions facing the long axis direction and the short axis direction.
[0030]
A seal member 80 is attached to the inside of the annular protrusion 73. The seal member 80 is made of low-density polyethylene and has elasticity, and has a cylindrical shape with an elliptical cross section. The upper part is a small diameter part 81 and the lower part is a large diameter part (elastic cylinder part) 82. On the outer peripheral surface of the small-diameter portion 81, one vertical protrusion is formed at each portion facing the major axis direction and the minor axis direction.
[0031]
The small diameter portion 81 is inserted into the annular protrusion 73 and is positioned by inserting the vertical protrusion of the small diameter portion 81 between the vertical protrusions of the annular protrusion 73 at the time of insertion. And the sealing member 80 is being fixed to the lid cylinder 70 by sticking and fixing the top-plate part of the small diameter part 81 to the top part of the lid cylinder 70 with the double-sided adhesive tape 90. FIG.
[0032]
The large-diameter portion 82 has a shape that spreads downward, and an annular bulging portion 83 that bulges inward is provided in the middle of the inner peripheral surface, and an annular protruding outward is formed at the lower edge of the outer peripheral surface. The seal protrusion 84 is provided.
[0033]
As shown by a two-dot chain line in FIG. 3, when the cover cylinder 70 is not fitted, the inner surface of the bulging portion 83 is formed slightly smaller than the outer peripheral surface of the front portion of the small-diameter portion 13 of the outer cylinder 10. The outer peripheral surface of the seal projection 84 is formed slightly smaller than the inner peripheral surface of the peripheral wall portion of the lid cylinder 70 on the entire periphery.
[0034]
When the cover cylinder 70 is fitted to the outer cylinder 10, the small-diameter portion 13 of the outer cylinder 10 is fitted inside the bulging portion 83 while expanding the bulging portion 83 outward, and as a result, the outer diameter portion The front end of 82 is also pushed outward, so that the entire circumference of the outer peripheral surface of the seal projection 84 is in pressure contact with the inner peripheral surface of the peripheral wall portion of the lid cylinder 70.
[0035]
That is, the large-diameter portion 82 of the sealing member 80 is sandwiched between the small-diameter portion 13 of the outer cylinder 10 and the peripheral wall portion of the lid cylinder 70 and is elastically deformed when the lid cylinder 70 is fitted. Due to the elastic restoring force, the bulging portion 83 strongly presses the outer peripheral surface of the small-diameter portion 13 of the outer cylinder 10 around the entire circumference and seals the space therebetween, and the seal projection 84 extends around the inside of the lid cylinder 70 around the entire circumference. The peripheral surface is strongly pressed to seal between them.
[0036]
In addition, an air vent hole 86 is formed in the seal member 80 at a portion facing the short axis direction in the step portion 85 between the small diameter portion 81 and the large diameter portion 82. The air vent hole 86 is for releasing the air pressure pressurized in the seal member 80 during the fitting operation of the lid cylinder 70 to the outside.
[0037]
That is, the inside of the seal member 80 communicates with the space 87 between the lid cylinder 70 and the seal member 80 through the air vent hole 86, and when the pressure in the space 87 rises, the pressure of the seal member 80 is increased by the pressure. The tip portion of the diameter portion 82 is elastically deformed inward to form a gap between the seal protrusion 84 and the inner peripheral surface of the peripheral wall portion of the lid cylinder 70, and pressure is released from this gap. When the air pressure escapes and the pressure in the space 87 decreases, the tip of the large-diameter portion 82 expands again, and the seal projection 84 presses against the inner peripheral surface of the peripheral wall portion of the lid cylinder 70 and seals.
[0038]
In the stick-shaped cosmetic material supply container having the above-described configuration, the outer cylinder portion 52 of the operation member 50 has a bottomed cylindrical shape, and the annular wall portion 19 of the outer cylinder 10 and the seal ring portion 55 of the operation member 50 are in a sealed state. The conversion mechanism is accommodated inside the outer tube portion 52 and the seal ring portion 55 and the annular wall portion 19, and the seal member 80 is interposed between the outer tube 10 and the cover tube 70 when the cover tube 70 is fitted. Since the large-diameter portion 82 is sealed, the bar-shaped cosmetic is stored in a sealed space surrounded by the outer cylinder 10, the operation member 50, the seal member 80, and the lid cylinder 70. Therefore, even if the stick-shaped cosmetic contains a volatile component, the volatilization of the volatile component can be prevented.
[0039]
And since the seal part in the sliding part (that is, the sliding part of the annular wall part 19 and the seal ring part 55) is an annular shape, the structure is simple, the moldability is good, and the sealing property is good. be able to. Further, it is not necessary to provide a sealing structure for the elliptical sliding part (that is, between the dish part 31 and the small diameter part 13 of the outer cylinder 10), which is difficult to obtain a complete sealing structure.
[0040]

FIG. 6 shows a cross section along the minor axis direction, and FIG. 7 shows the major axis direction. A cross section is shown.
[0041]
The second embodiment differs from the first embodiment in the mounting structure of the seal member 80 and the installation position of the air vent hole 86.
That is, the top part of the cover cylinder 70 in the second embodiment bulges into a convex curved surface, and a space is formed between the top part of the seal member 80. Therefore, instead of sticking the sealing member 80 to the lid cylinder 70 with the double-sided adhesive tape 90, a standing wall portion 88 is provided on the top plate portion of the small diameter portion 81 of the sealing member 80, and the standing wall portion 88 is attached to the lid cylinder 70. An engaging projection 89 is provided on the outer peripheral surface of the small-diameter portion 81 so as to project outward, and this engaging projection 89 is engaged with an engaging groove 74 provided on the upper inner peripheral surface of the lid cylinder 70. Thus, the seal member 80 is fixed so as not to move up and down. Note that the circumferential positioning structure of the seal member 80 is the same as in the first embodiment, whereby the seal member 80 is fixed so as not to rotate. The air vent hole 86 is provided in the small diameter portion 81. Other points are the same as those of the first embodiment.
