【発明の属する技術分野】
本発明は、蓋体の内面に弾性シール部材を取付けてあるスタンプ台に関する。
【０００２】
【従来の技術】
インクパッドを備えたスタンプ台本体の一側に、前記インクパッドを覆う蓋体を枢着してある構成のスタンプ台は古くから知られている。そして、そのようなスタンプ台のうち、閉蓋状態におけるインク漏れやインクの揮発を防止するために、蓋体の内面に弾性シール部材を取付けてあるスタンプ台が存在する。そのようなスタンプ台として、実開平６−５７６６１号や特開平６−２７８３５２号に開示されたものがあり、そこに開示されたスタンプ台では、蓋体の内面に嵌合溝を周設してあり、その嵌合溝に断面が樋状をした弾性シール部材の嵌合凸条を嵌合することより、弾性シール部材を蓋体の内面に取付けてある。
【０００３】
ところが、前記したようなスタンプ台では、弾性シール部材はその嵌合凸条と蓋体の嵌合溝との嵌合力だけで蓋体内面に取付けられた状態で保持されているため、スタンプ台の長期間の使用により蓋体の開閉回数が多くなったり、蓋体の開閉操作をする際に指先を弾性シール部材に引っ掛けたりすると、弾性シール部材が蓋体から外れてしまうという問題があった。特に、前記した実開平６−５７６６１号や特開平６−２７８３５２号に開示されたようなスタンプ台では、蓋体前側（枢着側と相対する側）を天面が下向きに傾斜した薄い形状としているが、このように蓋体の開閉操作をする際に最も指が触れやすい部分となる蓋体前側が薄い形状をしている場合には、蓋体の開閉操作をする際に指先を蓋体の内面にある弾性シール部材に引っ掛けやすくなってしまい、これにより、蓋体の開閉操作時に弾性シール部材が外れてしまうことが頻繁に起こるという問題があった。
【０００４】
【発明が解決しようとする課題】
そこで、本発明は、スタンプ台の長期使用により蓋体の開閉回数が多くなったり、蓋体の開閉操作時において指先を弾性シール部材に引っ掛けたとしても、弾性シール部材が簡単に外れてしまうことのないスタンプ台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】
インクパッドを備えたスタンプ台本体の一側に弾性シール部材を内面に取付けた前記インクパッドを覆う蓋体を枢着してあるスタンプ台において、
前記蓋体の内面には、長方形状の内周壁と、その内周壁を囲む長方形状の外周壁を立設してあり、前記内周壁と前記外周壁との間を長方形状の溝部とし、前記内周壁又は前記外周壁に切欠部を設け、
前記弾性シール部材には、前記溝部に嵌合する嵌合凸条を一体に設け、前記嵌合凸条の側面の前記切欠部に対応する位置に前記切欠部と嵌合する嵌合部を設け、前記嵌合凸条と平行に前記嵌合部の一端と繋がった壁部を設け、
前記溝部と前記嵌合凸条を嵌合し、前記切欠部と前記嵌合部を嵌合し、前記切欠部を設けた前記内周壁又は前記外周壁と前記壁部を密接したことを特徴とするスタンプ台。
【０００７】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を図面を用いて詳細に説明する。図１〜図６は本発明のスタンプ台の一実施の形態を示すものである。１はスタンプ台本体であり、上面が開口した長方形箱型のプラスチック製の底容器２と、底容器２に上方より嵌合される長方形枠状のプラスチック製の枠体３と、底容器２と枠体３の間に収容されるインクパッド４とから構成されるものである。インクパッド４は、底容器２上に載置されるクッション材５と、クッション材５の上に積層されるインク吸蔵体６と、インク吸蔵体６の上面を覆う表布７とからなるもので、クッション材５とインク吸蔵体６は差し加工により一体としてあり、表布７の周縁は枠体３に熱融着や超音波融着の方法により固着されている。尚、クッション材５の材質としては発泡ポリエチレンや発泡ポリスチレン等が挙げられ、インク吸蔵体６の材質としては羊毛フェルトやポリエステルフェルト等が挙げられ、表布７の材質としては綿やポリエステル等が挙げられる。
【０００８】
８はインクパッド４の表布７の上面を覆う長方形状のプラスチック製の蓋体であり、後側面中央に設けられた軸部９の左右両端の枢軸１０をスタンプ台本体１の後側面左右２ヶ所に設けられた軸受け１１に保持させることにより、スタンプ台本体１に回転可能に枢着されているものである。尚、蓋体８の前側は天面を下向きに傾斜させた薄い形状としている。そして、図３、図４、図５に示すように、蓋体８の内面には長方形状の内周壁１２と、その内周壁１２を囲む長方形状の外周壁１３を立設してあり、その内周壁１２と外周壁１３との間を長方形状の溝部１４としている。又、外周壁１３より外周には前記溝部１４より深さが浅い外溝部１５を設けてある。更に、溝部１４の側壁となる前記内周壁１２の四辺のうち、薄い形状となっている蓋体８前側に位置する一長辺には切欠部１６を一定の間隔で３ヶ所に設けてある。
【０００９】
１７は蓋体８の内面に取付けられた長方形枠状のシリコンゴム製の弾性シール部材である。この弾性シール部材１７は、図６に示すように、中央が開口した長方形枠状の底辺部１８の上面内周側に前記溝部１４と嵌合する長方形状の嵌合凸条１９を一体に設け、底辺部１８の上面外周側に高さが嵌合凸条１９より低い長方形状の側辺部２０を一体に設けてあるもので、断面形状が樋状となっている。そして、この弾性シール部材１７の底辺部１８の下面には、蓋体８を閉じた状態においてインクパッド４を囲むように枠体３の上面に密接する隆条２１を一体に周設してあるので、蓋体８を閉じた状態では、この弾性シール部材１７のシール効果によりインクパッド４のインク漏れやインクの揮発を防止することができる。又、前記嵌合凸条１９の一長辺側面であって前記切欠部１６に対応する位置３ヶ所には、嵌合凸条１９を溝部１４に嵌合した時に切欠部１６に入り込んで、該切欠部１６と嵌合する凸状の嵌合部２２を一体に設けてある。
【００１０】
つまり、前記弾性シール部材１７は、嵌合凸条１９を溝部１４に嵌合すると共に、嵌合部２２を切欠部１６に嵌合することにより蓋体８の内面に取付けられるものであり、その嵌合凸条１９と溝部１４の嵌合力と、嵌合部２２と切欠部１６の嵌合力によって、蓋体８の内面に取付けられた状態で保持されるものである。従って、蓋体８の開閉回数が多くなったり、蓋体８の開閉操作時において指先を弾性シール部材１７に引っ掛けるなどして、弾性シール部材１７に蓋体８から外れるような力が加わったとしても、弾性シール部材１７は嵌合凸条１９と溝部１４の嵌合力と、嵌合部２２と切欠部１６の嵌合力により、蓋体８から簡単に外れることはない。尚、弾性シール部材１７を蓋体８の内面に取付けた時、弾性シール部材１７の側辺部２０の外周側面は蓋体８の外溝部１５の内周側面に密接した状態となる。
【００１１】
更に、前記弾性シール部材１７の底辺部１８の中央開口縁であって、前記嵌合部２２を設けた側の一長辺には、前記嵌合部２２を設けた嵌合凸条１９と平行な壁部２３を一体に設けてある。この壁部２３の内側面は嵌合部２２の一端と繋がっており、壁部２３の内側面と、該内側面と対向する嵌合凸条１９の一長辺側面との間には、切欠部１６を設けた内周壁１２の一長辺が入り込む溝２４が形成されている。そして、嵌合凸条１９を溝部１４に嵌合すると共に嵌合部２２を切欠部１６に嵌合した時、内周壁１２の一長辺は溝２４内に入り込んで、互いに対向する壁部２３の内側面と内周壁１２の一長辺側面は密接した状態となる。
【００１２】
従って、弾性シール部材１７に前記したような壁部２３を設けた場合には、蓋体８の開蓋操作時に指先を弾性シール部材１７に引っ掛けるなどして、弾性シール部材１７に蓋体８から外れるような力が加わったとしても、嵌合凸条１９と溝部１４の嵌合力と、嵌合部２２と切欠部１６の嵌合力に加え、内周壁１２の一長辺側面と壁部２３の内側面の密接部分における摩擦力により、弾性シール部材１７は蓋体８からより外れにくいものとなる。尚、このような壁部２３は、本実施の形態のように、蓋体８の開閉操作をする際に指が最も触れやすい部分となる蓋体前側が薄い形状をしている場合や、蓋体全体が薄い形状をしている場合に設けると効果的である。又、このような壁部２３を設けることにより、蓋体８の内面に弾性シール部材１７を取付けた際、切欠部１６と嵌合部２２を隠して外部に全く表れない状態とするので、蓋体内面のデザイン性も損なうことがない。
【００１３】
尚、本実施の形態では、スタンプ台本体１の前側中央部分に開蓋ボタン２５を揺動自在に枢着してある。この開蓋ボタン２５は、図２に示すように枠体３の前辺上面と連続して常時外部に露呈する部分を操作部２６としており、その操作部２６の後端中央部に押上部２７を設けると共に、その押上部２７の左右両側に２つの爪２８を設けてある。又、図２、図３に示すように、蓋体８の前方内面には閉蓋状態において前記開蓋ボタン２５の爪２８と係合する２つの爪受け２９を設けてあり、爪２８と爪受け２９が係合することにより、蓋体８は閉蓋状態においてロックされるようにしてある。更に、図１に示すように、底容器２の前側であって開蓋ボタン２５の下方には操作部２６を常時上方に付勢するスプリング３０が設けてある。そして、閉蓋状態においては蓋体８の前方内面が開蓋ボタン２５の押上部２７上面に当接するものとしているので、この状態で開蓋ボタン２５の操作部２６をスプリング３０の弾発力に抗して押し下げることにより、開蓋ボタン２５が揺動して押上部２７が蓋体８を押し上げるので、これにより爪２８と爪受け２９の係合が解かれて、開蓋することができる。
【００１４】
以上、本発明の実施の形態として、蓋体８の内面にある溝部１４の側壁となる内周壁１２の、蓋体前側に位置する一長辺の３ヶ所に切欠部１６を設け、弾性シール部材１７の嵌合凸条１９の一長辺側面の、前記切欠部１６に対応する位置３ヶ所に切欠部１６と嵌合する嵌合部２２を一体に設け、更に弾性シール部材１７の底辺部１８の開口縁の、前記嵌合部２２を設けた嵌合凸条１９側の一長辺に内側面が前記内周壁１２の一長辺側面と密接する壁部２３を一体に設けたものについて説明してきたが、本発明は前記した実施の形態のみに限定されるものではなく、前記した実施の形態以外にも適宜設計を変更して実施することが可能である。
【００１５】
例えば、切欠部１６を蓋体前側に位置する内周壁１２の一長辺と、内周壁１２の対向する二短辺の計三辺に設け、嵌合部２２を嵌合凸条１９の三辺側面の前記切欠部１６に対応する位置に設け、更にその嵌合部２２を設けた三辺の嵌合凸条１９とそれぞれ平行な壁部２３を底辺部１８の開口縁三辺に設けても良く、又、切欠部１６、嵌合部２２、壁部２３をそれぞれ内周壁１２、嵌合凸条１９、底辺部１８の開口縁の四辺全てに設けても良い。
【００１６】
又、蓋体８が深い箱状のような厚い形状のものである場合には、蓋体８の溝１４の深さを深くすると共に弾性シール部材１７の嵌合凸条１９の高さを高くして、更に切欠部１６と嵌合部２２の高さも高くすることにより、その分、嵌合凸条１９と溝部１４の嵌合力、及び嵌合部２２と切欠部１６の嵌合力を大きくすることができるので、そのような場合には壁部２３を設けずに、切欠部１６と嵌合部２２だけを設けても良い。
【００１７】
更に、前記した実施の形態では、切欠部１６を溝部１４の側壁となる内周壁１２に設けていたが、切欠部１６は溝部１４の側壁となる外周壁１３に設けても良く、その場合、その切欠部１６と嵌合する嵌合部２２は、嵌合凸条１９の側面の、外周壁１３の切欠部１６に対応する位置に設ければ良い。又、切欠部１６と嵌合部２２は前記した実施の形態ではそれぞれ一辺につき３ヶ所に設けていたが、弾性シール部材１７が蓋体８の内面から簡単に外れることのない嵌合力を得るためにも、切欠部１６と嵌合部２２はそれぞれ一辺につき２ヶ所以上設けるのが望ましい。
【００１８】
【発明の効果】
以上の通り、本発明はスタンプ台本体の一側に枢着された蓋体の内面に周設された溝部の側壁に切欠部を設け、弾性シール部材の前記溝部と嵌合する嵌合凸条の側面であって、前記切欠部に対応する位置に前記切欠部と嵌合する嵌合部を設け、前記嵌合凸条と前記溝部の嵌合力と、前記嵌合部と前記切欠部の嵌合力により、弾性シール部材を蓋体内面に取付けた状態に保持するものとしたので、スタンプ台の長期使用によって蓋体の開閉回数が多くなったり、蓋体の開閉操作時において指先を弾性シール部材に引っ掛けるなどして、弾性シール部材に蓋体から外れるような力が加わったとしても、弾性シール部材は蓋体から簡単に外れることはない。
【００１９】
又、前記弾性シール部材に、前記嵌合部を設けた嵌合凸条と平行で内側面が前記切欠部を設けた側壁の側面に密接する壁部を設けることにより、弾性シール部材は、嵌合凸条と溝部の嵌合力と、嵌合部と切欠部の嵌合力と、切欠部を設けた側壁側面と壁部内側面の密接部分における摩擦力の３つの力により蓋体内面に取付けられた状態で保持されるので、弾性シール部材は蓋体からより外れにくいものとなる。そして、このような壁部を弾性シール部材に設けることは、蓋体が薄い形状をしたスタンプ台には特に有用である。
【００２０】
更に、本発明における弾性シール部材を蓋体内面に取付ける際、嵌合凸条を蓋体内面の溝部に嵌合させると、それと同時に嵌合凸条の嵌合部と溝部側壁の切欠部も嵌合し、又、壁部を設けた場合には、嵌合凸条と溝部の嵌合、及び嵌合部と切欠部の嵌合と同時に、壁部の内側面が切欠部を設けた側壁側面と密接するので、本発明における弾性シール部材の取付け作業は、弾性シール部材の嵌合凸条と蓋体内面の溝部との嵌合のみで蓋体内面に取付ける従来の作業と何ら変わりはない。従って、本発明によれば、スタンプ台の組み付け時における工程や手順を変更したり増やしたりすることなく、又、大きな設計変更を加えることなく、弾性シール部材の外れ防止を図ったスタンプ台を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a stamp base having an elastic seal member attached to the inner surface of a lid.
[0002]
[Prior art]
A stamp stand having a structure in which a lid covering the ink pad is pivotally attached to one side of a stamp stand main body provided with an ink pad has been known for a long time. Among such stamp stands, there is a stamp stand having an elastic seal member attached to the inner surface of the lid in order to prevent ink leakage and ink volatilization in the closed state. As such stamp stands, there are those disclosed in Japanese Utility Model Laid-Open No. 6-57661 and Japanese Patent Laid-Open No. 6-278352. In the stamp stands disclosed therein, a fitting groove is provided on the inner surface of the lid. The elastic sealing member is attached to the inner surface of the lid body by fitting the fitting groove of the elastic sealing member having a hook-like cross section into the fitting groove.
[0003]
However, in the stamp table as described above, the elastic seal member is held in a state of being attached to the inner surface of the lid body only by the fitting force between the fitting protrusion and the fitting groove of the lid body. There has been a problem that the elastic seal member comes off from the lid when the number of times the lid is opened or closed increases due to long-term use, or when the fingertip is hooked on the elastic seal member when the lid is opened or closed. In particular, in the stamp stand as disclosed in Japanese Utility Model Laid-Open No. 6-57661 and Japanese Patent Application Laid-Open No. 6-278352, the front side of the lid (the side opposite to the pivoting side) has a thin shape with the top surface inclined downward. However, if the front side of the lid, which is the part most easily touched by the fingers when opening and closing the lid, has a thin shape, the fingertip should be removed when opening and closing the lid. There is a problem that the elastic seal member is easily hooked on the inner surface of the cover, and the elastic seal member is frequently detached during the opening / closing operation of the lid.
[0004]
[Problems to be solved by the invention]
Therefore, according to the present invention, the elastic seal member can be easily detached even if the number of times of opening and closing of the lid increases due to long-term use of the stamp stand or even when the fingertip is hooked on the elastic seal member during the opening and closing operation of the lid. The purpose is to provide a stamp stand without any.
[0005]

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1-6 shows one Embodiment of the stamp stand of this invention. Reference numeral 1 denotes a stamp base body, a rectangular box-shaped plastic bottom container 2 having an open top surface, a rectangular frame-shaped plastic frame body 3 fitted to the bottom container 2 from above, a bottom container 2, The ink pad 4 is accommodated between the frames 3. The ink pad 4 is composed of a cushion material 5 placed on the bottom container 2, an ink storage body 6 stacked on the cushion material 5, and a surface cloth 7 that covers the upper surface of the ink storage body 6. The cushion material 5 and the ink occlusion body 6 are integrated by insertion processing, and the peripheral edge of the outer cloth 7 is fixed to the frame body 3 by heat fusion or ultrasonic fusion. Examples of the material of the cushion material 5 include foamed polyethylene and polystyrene foam, examples of the material of the ink occlusion body 6 include wool felt and polyester felt, and examples of the material of the outer cloth 7 include cotton and polyester. It is done.
[0008]
Reference numeral 8 denotes a rectangular plastic lid that covers the upper surface of the front cloth 7 of the ink pad 4. The pivots 10 at the left and right ends of the shaft portion 9 provided at the center of the rear side are connected to the left and right sides 2 of the stamp base body 1. It is pivotally attached to the stamp base body 1 by being held by bearings 11 provided at locations. Note that the front side of the lid 8 has a thin shape with the top surface inclined downward. 3, 4, and 5, a rectangular inner peripheral wall 12 and a rectangular outer peripheral wall 13 surrounding the inner peripheral wall 12 are erected on the inner surface of the lid body 8. A rectangular groove 14 is formed between the inner peripheral wall 12 and the outer peripheral wall 13. An outer groove portion 15 having a shallower depth than the groove portion 14 is provided on the outer periphery of the outer peripheral wall 13. Further, of the four sides of the inner peripheral wall 12 serving as the side wall of the groove portion 14, three notches 16 are provided at regular intervals on one long side located on the front side of the thin lid 8.
[0009]
Reference numeral 17 denotes a rectangular frame-shaped silicon rubber elastic seal member attached to the inner surface of the lid 8. As shown in FIG. 6, the elastic seal member 17 is integrally provided with a rectangular fitting ridge 19 fitted to the groove portion 14 on the inner peripheral side of the upper surface of a rectangular frame-shaped bottom side portion 18 having an opening at the center. A rectangular side portion 20 having a height lower than that of the fitting ridge 19 is integrally provided on the outer peripheral side of the upper surface of the bottom portion 18, and the cross-sectional shape is a bowl shape. A ridge 21 that is in close contact with the upper surface of the frame 3 is integrally provided on the lower surface of the bottom portion 18 of the elastic seal member 17 so as to surround the ink pad 4 when the lid 8 is closed. Therefore, when the lid 8 is closed, the sealing effect of the elastic seal member 17 can prevent ink leakage from the ink pad 4 and ink volatilization. Further, at the three positions on one long side of the fitting ridge 19 and corresponding to the notch 16, when the fitting ridge 19 is fitted into the groove 14, it enters the notch 16, A convex fitting portion 22 that fits into the notch portion 16 is provided integrally.
[0010]
That is, the elastic seal member 17 is attached to the inner surface of the lid body 8 by fitting the fitting ridge 19 into the groove portion 14 and fitting the fitting portion 22 into the cutout portion 16. It is held in a state of being attached to the inner surface of the lid body 8 by the fitting force between the fitting ridge 19 and the groove portion 14 and the fitting force between the fitting portion 22 and the notch portion 16. Therefore, it is assumed that a force that causes the elastic seal member 17 to be detached from the lid body 8 is applied by, for example, increasing the number of times the lid body 8 is opened or closed, or hooking the fingertip onto the elastic seal member 17 during the opening / closing operation of the lid body 8. However, the elastic seal member 17 is not easily detached from the lid body 8 due to the fitting force between the fitting protrusion 19 and the groove portion 14 and the fitting force between the fitting portion 22 and the notch portion 16. When the elastic seal member 17 is attached to the inner surface of the lid body 8, the outer peripheral side surface of the side portion 20 of the elastic seal member 17 is in close contact with the inner peripheral side surface of the outer groove portion 15 of the lid body 8.
[0011]
Furthermore, the central opening edge of the bottom side portion 18 of the elastic seal member 17 is parallel to the fitting ridge 19 provided with the fitting portion 22 on one long side on the side where the fitting portion 22 is provided. The wall portion 23 is integrally provided. The inner side surface of the wall portion 23 is connected to one end of the fitting portion 22, and a notch is formed between the inner side surface of the wall portion 23 and the long side surface of the fitting protrusion 19 facing the inner side surface. A groove 24 into which one long side of the inner peripheral wall 12 provided with the portion 16 enters is formed. When the fitting ridge 19 is fitted into the groove portion 14 and the fitting portion 22 is fitted into the cutout portion 16, one long side of the inner peripheral wall 12 enters the groove 24, and the wall portions 23 facing each other. The inner side surface and the one long side surface of the inner peripheral wall 12 are in close contact with each other.
[0012]
Therefore, when the elastic seal member 17 is provided with the wall portion 23 as described above, a fingertip is hooked on the elastic seal member 17 when the lid body 8 is opened, so that the elastic seal member 17 is attached to the elastic seal member 17 from the lid body 8. Even if a force such as detachment is applied, in addition to the fitting force between the fitting ridge 19 and the groove 14 and the fitting force between the fitting portion 22 and the notch portion 16, one long side surface of the inner peripheral wall 12 and the wall portion 23. The elastic seal member 17 is more difficult to be detached from the lid body 8 due to the frictional force at the close portion of the inner surface. Note that such a wall portion 23 is formed when the front side of the lid, which is the portion most easily touched by a finger when the lid 8 is opened or closed, is thin, as in the present embodiment, It is effective when it is provided when the entire body has a thin shape. Further, by providing such a wall portion 23, when the elastic seal member 17 is attached to the inner surface of the lid body 8, the notch portion 16 and the fitting portion 22 are concealed so that they do not appear at all. The design of the inner surface of the body is not impaired.
[0013]
In the present embodiment, the opening button 25 is pivotally attached to the front center portion of the stamp base body 1 so as to be swingable. As shown in FIG. 2, the opening button 25 has a portion that is continuously exposed to the outside continuously from the upper surface of the front side of the frame 3 as an operation portion 26, and a push-up portion 27 at the center of the rear end of the operation portion 26. And two claws 28 are provided on the left and right sides of the push-up portion 27. As shown in FIGS. 2 and 3, the front inner surface of the lid 8 is provided with two claw receptacles 29 that engage with the claw 28 of the open button 25 in the closed state. The lid body 8 is locked in the closed state by the engagement of the receptacle 29. Further, as shown in FIG. 1, a spring 30 is provided on the front side of the bottom container 2 and below the opening button 25 so as to constantly urge the operation unit 26 upward. In the closed state, the front inner surface of the lid body 8 is in contact with the upper surface of the push-up portion 27 of the opening button 25, and in this state, the operating portion 26 of the opening button 25 is used as the spring force of the spring 30. By pushing down, the lid opening button 25 swings and the push-up portion 27 pushes up the lid 8, so that the engagement between the claw 28 and the claw receiver 29 is released and the lid can be opened.
[0014]
As described above, as an embodiment of the present invention, the cutout portions 16 are provided at three locations on one long side located on the front side of the lid body on the inner peripheral wall 12 which is the side wall of the groove portion 14 on the inner surface of the lid body 8, and an elastic seal member Fitting portions 22 for fitting with the notches 16 are integrally provided at three positions corresponding to the notches 16 on one side of the long side of the 17 fitting ridges 19, and the bottom portion 18 of the elastic seal member 17 is further provided. A description will be given of a case in which a wall portion 23 whose inner surface is in close contact with one long side surface of the inner peripheral wall 12 is integrally provided on one long side of the opening edge of the fitting protrusion 19 provided with the fitting portion 22. However, the present invention is not limited to the above-described embodiment, and can be implemented by appropriately changing the design other than the above-described embodiment.

For example, the notch 16 is provided on a total of three sides of one long side of the inner peripheral wall 12 positioned on the front side of the lid and two short sides facing the inner peripheral wall 12, and the fitting part 22 is provided on the three sides of the fitting ridge 19. A wall portion 23 provided at a position corresponding to the notch portion 16 on the side surface and further parallel to the fitting protrusions 19 on the three sides provided with the fitting portion 22 may be provided on the three sides of the opening edge of the bottom portion 18. Alternatively, the notch 16, the fitting part 22, and the wall part 23 may be provided on all four sides of the opening edge of the inner peripheral wall 12, the fitting protrusion 19, and the bottom part 18, respectively.
[0016]
Further, when the lid 8 has a thick shape such as a deep box shape, the depth of the groove 14 of the lid 8 is increased and the height of the fitting protrusion 19 of the elastic seal member 17 is increased. Then, by further increasing the heights of the notches 16 and the fitting portions 22, the fitting force between the fitting protrusions 19 and the grooves 14 and the fitting force between the fitting portions 22 and the notches 16 are increased accordingly. Therefore, in such a case, the notch portion 16 and the fitting portion 22 may be provided without providing the wall portion 23.
[0017]
Furthermore, in the above-described embodiment, the notch 16 is provided on the inner peripheral wall 12 serving as the side wall of the groove 14, but the notch 16 may be provided on the outer peripheral wall 13 serving as the side wall of the groove 14. The fitting part 22 fitted to the notch part 16 may be provided at a position corresponding to the notch part 16 of the outer peripheral wall 13 on the side surface of the fitting ridge 19. Further, in the above-described embodiment, the notch portion 16 and the fitting portion 22 are provided at three places on each side, but in order to obtain a fitting force that the elastic seal member 17 does not easily come off from the inner surface of the lid body 8. In addition, it is desirable to provide two or more notches 16 and fitting portions 22 for each side.

【The invention's effect】
As described above, the present invention provides a fitting ridge that is provided with a notch in the side wall of the groove provided around the inner surface of the lid that is pivotally attached to one side of the stamp base body, and is fitted to the groove of the elastic seal member. A fitting portion that fits with the notch portion is provided at a position corresponding to the notch portion, the fitting force between the fitting protrusion and the groove, and the fitting between the fitting portion and the notch portion. Since the elastic seal member is held attached to the inner surface of the lid by the resultant force, the number of times of opening and closing of the lid increases due to long-term use of the stamp stand, and the fingertip is elastically sealed when the lid is opened and closed. Even if a force is applied to the elastic seal member so that the elastic seal member is detached from the lid, the elastic seal member is not easily detached from the lid.
[0019]
Further, the elastic seal member is provided with a wall portion that is parallel to the fitting protrusion provided with the fitting portion and whose inner side surface is in close contact with the side surface of the side wall provided with the notch portion. It was attached to the inner surface of the lid body by three forces including the fitting force between the mating ridge and the groove, the fitting force between the fitting portion and the notch portion, and the frictional force in the close contact portion between the side wall side surface provided with the notch portion and the inner side surface of the wall portion. Since it is held in a state, the elastic seal member is less likely to come off from the lid. Providing such a wall portion on the elastic seal member is particularly useful for a stamp base having a thin lid.
[0020]
Further, when the elastic seal member according to the present invention is attached to the inner surface of the lid body, when the fitting ridge is fitted into the groove portion on the inner surface of the lid body, the fitting portion of the fitting ridge and the notch portion on the side wall of the groove portion are also fitted at the same time. In addition, when the wall portion is provided, the side surface of the side wall in which the inner side surface of the wall portion is provided with the notch portion simultaneously with the fitting protrusion and the groove portion and the fitting portion and the notch portion. Therefore, the attaching operation of the elastic seal member in the present invention is not different from the conventional operation of attaching to the inner surface of the lid body only by fitting the fitting protrusion of the elastic seal member and the groove portion of the inner surface of the lid body. Therefore, according to the present invention, there is provided a stamp stand that prevents the elastic seal member from coming off without changing or increasing the number of steps and procedures at the time of assembling the stamp stand and without making a major design change. can do.
