Description

この発明は飲料を収容するカップ型容器に装着してその開封をするときに使用するオーバーキャップに関するものである。   The present invention relates to an overcap used when a cup-type container containing a beverage is attached and opened.

店頭で調整したホットコーヒーなどのホット飲料を店頭で購入して持ち帰るときに使用するカップ型容器では、客の注文毎にカップにホットコーヒーを入れ、これにカップの上から簡易のカバーキャップをかぶせて、顧客に手渡される。
この簡易のカバーキャップには、縁部に飲み口と空気入口が形成されていて、客はカバーキャップをカップから外さずに、飲み口を通して内容物を飲用する（特許文献１参照）。
一方飲料メーカーが工場にて調整、販売するカップ飲料では、飲料メーカーが飲料をカップに充填し、保存性、衛生性を保持することなどを目的として、カップの上端をフィルム状の蓋材でシールして出荷する。このカップ飲料でもカップの上面にシール蓋を保護するためのオーバーキャップを装着してシール蓋を覆うが、このシール蓋を剥さずにオーバーキャップの上からカップ内の飲料を飲むことが要求されて来ている。 For cup-type containers used when purchasing hot beverages such as hot coffee adjusted at the store and taking them home, put hot coffee in the cup for each customer order and put a simple cover cap on the cup. And handed to the customer.
In this simple cover cap, a drinking mouth and an air inlet are formed at the edge, and the customer drinks the contents through the drinking mouth without removing the cover cap from the cup (see Patent Document 1).
On the other hand, in the case of cup beverages that are adjusted and sold at the factory by the beverage manufacturer, the beverage manufacturer seals the upper end of the cup with a film-like lid so that the beverage is filled into the cup and preserves storability and hygiene. Then ship. Even in this cup beverage, an overcap for protecting the seal lid is attached to the upper surface of the cup to cover the seal lid, but it is required to drink the beverage in the cup from above the overcap without peeling off this seal lid. Is coming.

特開２００４−１２３１５５号JP 2004-123155 A 特願２００７−０２３５０６号Japanese Patent Application No. 2007-023506

しかし店頭販売用カップ用のカバーキャップを工場調整飲料用のカップ用オーバーキャップとしてそのまま転用することはできない。これを、シール蓋を有するカップに転用すると、飲み口を形成する際のシール蓋開口のときにキャップの取外し、及び再取付が必要であるし、別に開口器具が必要になることもある。また、工場調整飲料用カップの場合はカップ上端にシール蓋が存在するので、飲む時はシール蓋を開口させるための手段が必要になる。しかも、内容物がホットの高温飲料や有色飲料の場合は、内容物が開口操作時の振動で波立ってカップの外にあふれ出る事故を防ぐために、シール蓋を開口させる動作を特に静かに円滑に行うことができるものであることが望まれる。
シール蓋を切開して飲み口を形成する開口具としては特許文献１に記載したものがあるが、これらの開口具ではカップ上端に装着したオーバーキャップにカッターがヒンジを介して連結していて、このカッターがスイングしてシール蓋と接触して切開するものである。しかるにシール蓋には内容品の注出性向上のための空気を導通させる空気孔の必要もあるので、例えば開口部を大きく形成するなどの措置を講じる必要が生じ、その結果、飲み口形成のための操作に大きな力を要していた。
また本出願人は新たなオーバーキャップの提案も行った（特許文献２）。 However, the cover cap for cups for over-the-counter sales cannot be used as it is as an overcap for cups for factory adjusted beverages. When this is diverted to a cup having a seal lid, the cap needs to be removed and reattached when the seal lid is opened when forming the drinking mouth, and an opening device may be required separately. In the case of a factory-adjusted beverage cup, a sealing lid is present at the upper end of the cup, so that means for opening the sealing lid is required when drinking. In addition, when the contents are hot high-temperature drinks or colored drinks, the operation of opening the seal lid is particularly smooth and smooth to prevent the contents from spilling out of the cup due to vibration during opening operation. It is desirable that it can be performed.
Although there is what was described in patent document 1 as an opening tool which incises a seal lid and forms a drinking mouth, in these opening tools, a cutter is connected to an overcap attached to the upper end of a cup via a hinge, This cutter swings and makes an incision in contact with the seal lid. However, the seal lid also needs an air hole for conducting air to improve the pouring of the contents, so it is necessary to take measures such as forming a large opening. It took a lot of power to operate.
The applicant has also proposed a new overcap (Patent Document 2).

この新たに提案されたオーバーキャップは切刃を持つ切開部材を天板にヒンジ結合させて備えておいて、指掛り部材を操作して切開部材をシール蓋に押し込んで切開して流出口空気孔を開口させるもので、きわめて簡単な操作で流出口や空気孔を形成することができ、安全性も高いものである。
しかしながら、この新たに提案されたオーバーキャップは、従来のオーバーキャップに対して開口操作性の点などで優れた効果を有するものの、操作の手順や方法が消費者に伝わりにくいという問題点が見つかった。 This newly proposed overcap has an incision member with a cutting blade hinged to the top plate, and operates the finger hook member to push the incision member into the seal lid and incise it to make an outlet air hole. The outlet and the air hole can be formed by a very simple operation, and the safety is high.
However, although this newly proposed overcap has an excellent effect in terms of opening operability and the like over the conventional overcap, it has been found that the operation procedure and method are difficult to communicate to consumers. .

この発明は上記の如き事情に鑑みてなされたものであって、流出口や空気孔の形成が容易で、構造も簡単であり、購買者が切開部材の構造を見ただけで、その操作方法も推測し、理解し易いオーバーキャップを提供することを目的とするものである。   The present invention has been made in view of the circumstances as described above, and it is easy to form an outlet and an air hole, and the structure is simple. It is also intended to provide an overcap that is easy to guess and understand.

この目的に対応して、この発明のオーバーキャップは、

前記切開部材は前記シール蓋を切開可能な切刃と前記切刃が突出して形成されている切刃保持部材と
前記切刃保持部材の前記ヒンジ寄り基端部近傍より上方へ立ち上がる立設壁と前記立設壁にその先端部近傍が連接するとともに他端が前記ヒンジに連接していて、前記切開部材を回動させる押圧力を受けることが可能な指掛り部材とを備え、
前記切刃保持部材と前記指掛り部材とはそれぞれ前記容器の中心線と所定角度をなすとともに、前記指掛り部材を前記穿孔内に回動させたときに、前記穿孔の縁と前記指掛り部材の外縁との間に液体または空気が流通可能な間隙が形成される
ことを特徴としている。 Corresponding to this purpose, the overcap of the present invention is

The mounting skirt 12 has an undercut-like locking portion 17 protruding radially around the center line 14, and this locking portion 17 is a shoulder when the overcap body 6 is attached to the cup-type container 2. The flange 3 and the overcap main body 6 are fixed by sandwiching the flange 3 of the cup-shaped container 2 in cooperation with 13. At this time, since a sealing member such as a contact ring or fin 18 (FIG. 9) is provided on the lower surface of the shoulder 13 so as to be in liquid-tight contact with the upper surface of the flange 3, the cup-shaped container 2 of the overcap 1a. And liquid-tight mounting.
The overcap body 6 has a recess 21 above the top plate 16 at a central position, and has a peripheral wall 15 surrounding the recess 21 and rising around the center line 14.
A perforation 22 is formed in an edge portion corresponding to one end portion of the top plate 16 in the diameter direction in the vicinity of the outflow guide wall 38 of the peripheral wall 15. The perforation 22 is a hole used as a hole through which the content liquid in the cup-type container 2 flows or a hole through which breathing air flows. On both sides of the perforations 22, the ridges 23 are formed with the top plate 16 facing upward. The raised portion 23 has a function of concentrating the flow in the oral cavity of the drinker by suppressing the content flowing out of the perforation 22 from flowing in the lateral direction, and has an inclined surface. Do not hit the lips.
A cutting member 7 is disposed in the perforation 22 and is connected to the top plate 16 via a thin hinge 10 at the base end.

切開部材７はシール蓋５を切開するための部材で、シール蓋５を切って切開する機能を有する。   The incision member 7 is a member for incising the seal lid 5 and has a function of incising by cutting the seal lid 5.

切開部材７はヒンジ１０回りに回動して穿孔２２を通して変位可能である。   The incising member 7 can be displaced through the perforation 22 by rotating around the hinge 10.

切開部材７はシール蓋５を切開可能な切刃２４とその切刃２４を突出させている切刃保持部材２５と指掛り部材２６とからなっている。   The incision member 7 includes a cutting edge 24 that can incise the seal lid 5, a cutting edge holding member 25 that projects the cutting edge 24, and a finger hook member 26.

切刃２４は切刃保持部材２５の先端部下面から下方に突出している。切刃２４は鋭利な下端を有していてシール蓋５を切開可能である。   The cutting blade 24 protrudes downward from the lower surface of the distal end portion of the cutting blade holding member 25. The cutting edge 24 has a sharp lower end and can cut the seal lid 5.

切刃保持部材２５は平面視が穿孔２２とほぼ相似の形状をなすが、大きさは穿孔２２よりもやや小さく、穿孔２２内に配置されたときに穿孔２２の縁との間に隙間が形成される。
指掛り部材２６は板状をなしていて切刃保持部材２５の上方にあって先端部で立設壁７４を介して切刃保持部２５に固定しており、このとき指掛り部材２６と切刃保持部２５とはカップ型容器２の中心線とオーバーキャップ本体６の窪み２１の最奥部に形成された穿孔２２とがなす角度９０°よりも小さい角度をなしている。指掛り部材２６がヒンジ１０周りに回動して穿孔２２とほぼ一致する位置になったときに穿孔２２の先端部の縁との間に内容物の流出口２８を形成する。 The cutting blade holding member 25 has a shape substantially similar to the perforation 22 in plan view, but is slightly smaller in size than the perforation 22, and a gap is formed between the edges of the perforation 22 when placed in the perforation 22. Is done.
The finger hook member 26 has a plate shape and is located above the cutting blade holding member 25 and is fixed to the cutting blade holding portion 25 through a standing wall 74 at the tip portion. The blade holding portion 25 forms an angle smaller than 90 ° formed by the center line of the cup-shaped container 2 and the perforation 22 formed in the innermost portion of the recess 21 of the overcap body 6. When the finger hook member 26 rotates around the hinge 10 to a position that substantially coincides with the perforation 22, a content outlet 28 is formed between the edge of the front end of the perforation 22.

指掛り部材２６の上になる面には、操作手順や操作方法を示す指標３１が設けられている。指標３１は凹凸や平面図形で構成されていて、操作者が視認または触認が可能である。   An index 31 indicating an operation procedure or an operation method is provided on the surface above the finger hook member 26. The index 31 is configured by unevenness or a plane figure, and can be visually recognized or touched by an operator.

図１０に示すように、切刃２４と切刃保持部材２５と指掛り部材２６と立設壁７４とは補強リブ３２、３３、３４で相互の連結が補強されている。   As shown in FIG. 10, the cutting blade 24, the cutting blade holding member 25, the finger hook member 26, and the standing wall 74 are reinforced by mutual reinforcement ribs 32, 33, and 34.

オーバーキャップ本体６の周壁１５は天板１６の周縁を一周して形成されているが、そのうち穿孔２２の先端に対面する部分３５とその他の部分３６とでは構成が異なっていて、穿孔２２の先端に対面する部分は口当りをするマウスピースとなる部分で、この部分は内周面が他の部分より外側に凹入していて樋状になっている液体通路３７を持つとともに他の周壁１５よりも高い流出案内壁３８を構成している。この流出案内壁３８は中実構造のシングルウォール構造となっている。一方、その他の部分３６は全周にわたって等厚で、かつ中空の二重構造のダブルウォール構造になっている。   The peripheral wall 15 of the overcap body 6 is formed around the periphery of the top plate 16, and the configuration of the portion 35 facing the tip of the perforation 22 is different from that of the other portion 36. The portion that faces the mouthpiece is a mouthpiece that touches the mouth, and this portion has a liquid passage 37 that has a bowl-like shape in which the inner peripheral surface is recessed outward from the other portion, and from the other peripheral wall 15 Also, a high outflow guide wall 38 is formed. The outflow guide wall 38 has a solid single wall structure. On the other hand, the other portion 36 has a uniform double-wall structure having a uniform thickness over the entire circumference and a hollow double structure.

穿孔２２の側縁からは内方にストッパー片４１が舌片状に張り出している。このストッパー片４１は穿孔２２に達した指掛り部材２６と干渉可能で、この干渉により指掛り部材２６が穿孔２２を通り抜けてカップ型容器２側に入り込むのを防止する。   From the side edge of the perforation 22, a stopper piece 41 projects in a tongue shape inwardly. The stopper piece 41 can interfere with the finger hook member 26 that has reached the perforation 22, and the interference prevents the finger hook member 26 from passing through the perforation 22 and entering the cup-shaped container 2 side.

このように構成されたオーバーキャップ１ａの操作は次の通りである。   The operation of the overcap 1a configured as described above is as follows.

図１１、図１２に示すように、切開部材７の指掛り部材２６を指標３１に従って指で押し上げると、指掛り部材２６及びこれと一体となった切刃２４がヒンジ１０の周りに回転して下降し、切刃２４がシール蓋５を切開して流出口２８が開口する。指掛り部材２６が穿孔２２の高さと一致すると指掛り部材２６が穿孔２２の縁のストッパーに当接して停止し、流出口２８の開口が終了する。この状態でカップ型容器２を口許で傾けると、内容液は流出口２８から流出し、穿孔２２の縁と指掛り部材２６の外縁との間の隙間４２を通して注出され、さらに周壁１５の樋状の流出案内壁３８の液体通路３７に案内されて送りだされ、飲むことができる。   As shown in FIGS. 11 and 12, when the finger hooking member 26 of the incising member 7 is pushed up with a finger according to the index 31, the finger hooking member 26 and the cutting blade 24 integrated therewith rotate around the hinge 10. The cutting blade 24 cuts the seal lid 5 and the outlet 28 opens. When the finger hook member 26 coincides with the height of the perforation 22, the finger hook member 26 abuts against a stopper at the edge of the perforation 22 and stops, and the opening of the outflow port 28 is completed. When the cup-shaped container 2 is tilted with the mouth in this state, the content liquid flows out from the outlet port 28 and is poured out through the gap 42 between the edge of the perforation 22 and the outer edge of the finger hook member 26. It is guided to the liquid passage 37 of the spilled guide wall 38 and sent out for drinking.

図１３から図２１にはこの発明の第２の実施形態のオーバーキャップ１ｂが示されている。   13 to 21 show an overcap 1b according to a second embodiment of the present invention.

この第２の実施形態に係るオーバーキャップ１ｂでは、第１の実施形態に係るオーバーキャップ１ａの切開部材７とは別に、空気流通孔を形成するためだけの空気孔形成部材５１が設けられている。   In the overcap 1b according to the second embodiment, an air hole forming member 51 only for forming an air circulation hole is provided separately from the cutting member 7 of the overcap 1a according to the first embodiment. .

すなわち、天板１６に円形の開口５２が開設されており、その中に支持部材５３を介して空気孔形成部材５１が支持されている。空気孔形成部材５１は頂部に押しボタン部５４を有し、押しボタン部５４の下面から、突き刺し針５５が下方に向けて突出している。突き刺し針５５は下端にシール蓋５を突き刺して開口可能な鋭利な切刃５６を有している。また突き刺し針５５の側面には下端から押しボタン部５４の直下まで溝が形成されており、この溝は空気流通路５７を構成する。空気流通路５７の上端部は閉じて横向きの開口が形成されている。なお、突き刺し針５５を中空にして、その中空部を空気流通路５７とすることもできる。
支持部材５３は両端が薄肉のヒンジ６１を有し支持部材５３自体が板ばねとして機能するよう構成され天板１６と空気孔形成部材５１とともに一体に形成されている。 In other words, a circular opening 52 is formed in the top plate 16, and the air hole forming member 51 is supported through the support member 53 therein. The air hole forming member 51 has a push button portion 54 at the top, and a piercing needle 55 projects downward from the lower surface of the push button portion 54. The piercing needle 55 has a sharp cutting edge 56 that can be opened by piercing the seal lid 5 at the lower end. Further, a groove is formed on the side surface of the puncture needle 55 from the lower end to directly below the push button portion 54, and this groove constitutes an air flow passage 57. The upper end portion of the air flow passage 57 is closed to form a lateral opening. The piercing needle 55 can be made hollow and the hollow portion can be used as the air flow passage 57.
The support member 53 has thin hinges 61 at both ends, and the support member 53 itself is configured to function as a leaf spring, and is formed integrally with the top plate 16 and the air hole forming member 51.

このように構成されたオーバーキャップ１ｂにおける空気孔形成の操作は次の通りである。   The operation of forming air holes in the overcap 1b configured as described above is as follows.

切開部材７による開口部の形成とは別の操作で空気孔を形成する。この空気孔を形成すれば、そこから空気が流通するので切開部７による開口部においては空気の流通を確保する必要がないので、穿孔２２とこれを通過する切開部材は小さくすることができる。   The air hole is formed by an operation different from the formation of the opening by the cutting member 7. If this air hole is formed, air circulates from there, so there is no need to ensure air circulation at the opening portion by the incision portion 7, so that the perforation 22 and the incision member passing therethrough can be made small.

空気孔の形成操作として、空気孔形成部材５１の押しボタン部５４を下に押す。   As the air hole forming operation, the push button portion 54 of the air hole forming member 51 is pushed down.

押し下げられた押しボタン部５４は板ばね機能を有する支持部材５３が反転して下降し、押しボタン部５４の下面に設けられた切刃５６の先端がシール蓋を突き刺して容器内に入る。空気孔形成部材５１は突き刺し針５５（切刃５６）がシール蓋に突き刺さったままの姿勢を保つが空気は突き刺し針５５に形成された空気流通路５７を通って流通し、空気流のための通路が形成される。   The pushed-down push button portion 54 is lowered by the support member 53 having a leaf spring function being inverted, and the tip of the cutting blade 56 provided on the lower surface of the push button portion 54 pierces the seal lid and enters the container. The air hole forming member 51 maintains the posture in which the piercing needle 55 (cutting blade 56) is pierced into the seal lid, but the air flows through the air flow passage 57 formed in the piercing needle 55 and is used for air flow. A passage is formed.

図示した例では空気流通路５７の上端は外方に向いて開口しているので、カップ容器内の内圧が高まり開口時に内容液が吹き出すスプラッシュ現象が生じても、その吹き出しが直接に操作者に向いて吹きかかることはない。
このように構成されたオーバーキャップ１ｂでは、シール蓋を突き刺すことが可能な刺し刃部材を有する空気孔形成部材を有するので、空気孔の形成が容易で、内容物の注出を円滑にすることができる。
また突き刺し針に空気流通路が形成されているので、突き刺し針をシール蓋に突き刺したままでもカップ内への空気の流入が円滑である。
さらに突き刺し針は板ばね機能を有する支持部材によって支持されているので、シール蓋に突き刺す前後において、それぞれの姿勢を安定して維持することができる。また使用者に対して押ボタン５４がどの姿勢（位置）であるかを明示することができる。
この空気孔形成部材５１、支持部材５７は他の形式の切開部材をもつ他の形式のオーバーキャップにおいても使用することができる。例えば先に示した特許文献２の図１に開示されているオーバーキャップでは切開部材８を空気孔形成部材にしストラップヒンジ３４を支持部材とするストラップヒンジ形式の空気孔形成部材及び支持部材が切開部材７と組合わされて備えられているがこのストラップヒンジ形式の空気孔形成部材及び支持部材に替えて板ばね形式の空気孔形成部材５１及び支持部材５７を使用することもできる。
図２２から図２６にはこの発明の第３の実施形態のオーバーキャップ１ｃが示されている。
オーバーキャップ１ｃはカップ型容器に装着可能なオーバーキャップ本体６ｃとそのオーバーキャップ本体６ｃにヒンジ１０ｃを介して一体に連結して形成されている切開部材７ｃとからなっている。
オーバーキャップ本体６ｃはカップ型容器の上端部を覆う覆部１１ｃとこの覆部１１ｃをカップ型容器に取付けるための取付け裾部１２ｃとを肩部１３ｃを介してオーバーキャップ本体６ｃの中心線１４ｃ方向に同心状に連続させて有する。覆部１１ｃは筒状の周壁１５ｃとその下端を閉じる天板１６ｃとを有する。
オーバーキャップ本体６ｃは中央位置に天板１６ｃの上方に窪み２１ｃを有し、かつ窪み２１ｃを囲んで中心線１４ｃ周りに一周して立ち上がっている周壁１５ｃを有する。
天板１６ｃの直径方向の一端部に相当する縁部には周壁１５ｃの流出案内壁部３８ｃの直前に穿孔２２ｃが形成されている。穿孔２２ｃはカップ型容器内の内容液を流通させる孔または息継ぎ空気を流通させる孔として利用する孔である。穿孔２２ｃの両側では天板１６ｃが上方に盛り上って***部２３ｃが形成されている。
***部２３ｃは流出案内壁部３８ｃ寄りの下り斜面部７１ｃと反対寄りの上り斜面部７２ｃとからなっていて下り斜面部７１ｃと上り斜面部７２ｃとの境界線７３ｃが最も高くなっていて、この境界線７３ｃが後述する切開部材７ｃの指掛り部材２６ｃと立設壁７４ｃとの境界の側方に位置する。この下り斜面７１ｃ及び上り斜面７２ｃとも内側の穿孔２２ｃ寄りの部分よりも外側の周壁１５ｃ寄りの部分の方がやや高くなっている。
この***部２３ｃは切開部材７ｃに沿って位置していて、切開部材７ｃが他の物に接触して損傷するのを防ぐガードとしての機能を有し、かつ、穿孔２２ｃから流出した内容物が横方向に流れるのを抑制して飲用者の口腔に流れを集中させる機能を発揮する。
穿孔２２ｃ内には切開部材７ｃが配置されていて、基端部でヒンジ１０ｃを介して天板１６ｃに連結している。ヒンジ１０ｃは薄肉にして形成されている。 In the illustrated example, since the upper end of the air flow passage 57 opens outward, even if the internal pressure in the cup container increases and a splash phenomenon occurs in which the content liquid blows out at the time of opening, the blowout is directly directed to the operator. It doesn't blow away.
The overcap 1b configured as described above has an air hole forming member having a stab blade member that can pierce the seal lid, so that the air hole can be easily formed and the content can be smoothly poured out. Can do.
In addition, since the air flow passage is formed in the piercing needle, air can smoothly flow into the cup even when the piercing needle is stuck into the seal lid.
Furthermore, since the puncture needle is supported by a support member having a leaf spring function, the posture can be stably maintained before and after piercing the seal lid. In addition, it is possible to clearly indicate to the user which posture (position) the push button 54 is in.
The air hole forming member 51 and the supporting member 57 can be used in other types of overcaps having other types of cutting members. For example, in the overcap disclosed in FIG. 1 of Patent Document 2 shown above, a strap hinge type air hole forming member using the cutting member 8 as an air hole forming member and the strap hinge 34 as a supporting member and the supporting member are the cutting members. However, instead of the strap hinge type air hole forming member and support member, a leaf spring type air hole forming member 51 and support member 57 may be used.

The finger hook member 26c has a plate shape, is located above the cutting blade holding member 25c, and is fixed to the cutting blade holding portion 25c through the standing wall 74 at the distal end portion. The blade holding part 25 c forms an angle smaller than 90 ° with respect to the center line of the cup-shaped container 2. When the finger hook member 26c is rotated around the hinge 10c to a position substantially coinciding with the perforation 22c, an outlet port 28c for the contents is formed between the edge of the front end of the perforation 22c.

指掛り部材２６ｃの上になる面には、操作手順や操作方法を示す指標３１ｃが設けられている。指標３１ｃは凹凸や平面図形で構成されていて、操作者が視認または触認が可能である。   An index 31c indicating an operation procedure or an operation method is provided on the surface above the finger hook member 26c. The index 31c is composed of unevenness and a plane figure, and can be visually recognized or touched by the operator.

図２３に示すように、切開部材７ｃの上面において立設壁７４ｃと切刃保持部材２５ｃは補強リブ３２ｃで相互の連結が補強され、切開部材７ｃの下面において切刃２４ｃと切刃保持部材２５ｃと及び立設壁７４ｃと指掛り部材２６ｃは補強リブ３３ｃ、３４ｃで相互の連結が補強されている。
切開部材７ｃと穿孔２２ｃとの間には、図２５に示すように、２種類のストッパー構造、すなわち、通過防止ストッパー構造７５ｃと戻り防止ストッパー構造７６ｃとを備えている。
通過防止ストッパー構造７５ｃは、切開部材７ｃの基端部において指掛り部材２６ｃから側方に張り出す板状のストッパー片７７ｃが設けられる。指掛り部材２６ｃとストッパー片７７ｃとの間は補強リブ７８ｃが設けられて両者を連結し、補強している。
切開部材７ｃが切開動作として穿孔２２ｃ内に押し込まれたときに、切開部材７ｃが過度に穿孔２２ｃを行き過ぎてカップ型容器内に入り込むのを防止するためのストッパー構造であり、戻り防止ストッパー構造７６ｃは、逆に、穿孔２２ｃ内に押し込まれた切開部材７ｃがヒンジ１０ｃのっ弾性復元によって穿孔２２ｃ内に止まらずに、穿孔２２ｃ内から元の方向に戻り出てしまうのを切開部材７ｃを抑えて防ぐためのストッパー構造である。
通過防止ストッパー構造７５ｃでは***部２３ｃの穿孔２２ｃに向いた側面８ｃからストッパー８２ｃが穿孔２２ｃの内側に向って突出しており、また戻り防止ストッパー構造７６ｃでは同じ側面８１ｃからストッパー８３ｃが穿孔２２の内側に向って突出している。
これらのストッパー８２ｃ、８３ｃは共に切開動作として指掛り部材２６が穿孔２２ｃに入り込んだときに指掛り部材２６と干渉する位置に突出している。
通過防止用のストッパー８２ｃは、***部２３ｃの側面８１ｃからの突出量が大きく、太さも太く、剛性が大きく構成されているので切開部材７ｃのストッパー片７７ｃと当接した場合にも、ストッパー片７７ｃがストッパー８２ｃを乗り越えることがないので、切開部材７ｃの移動は穿孔２２ｃと一致する位置で停止される。一方、戻り防止ストッパー構造７６ｃのストッパー８３ｃは突出量も小さく、太さも細く、剛性が小さく、弾性撓みを起こし易い構造に構成されているので、切開部材７ｃの切開動作のときには、切開部材７ｃのストッパー片７７ｃは戻り防止用のストッパー８３ｃと当接したときには、ストッパー８３ｃを弾性撓みさせて戻り防止ストッパー７６ｃを乗り越えて穿孔２２と一致する位置まで達することができるが、このときには、戻り防止ストッパー構造７６ｃは元の状態に弾性復元しているので、その復元したストッパー７６ｃが切開部材７ｃのストッパー片７７ｃと当接して切開部材７ｃの戻り抜け出しを抑止する。 As shown in FIG. 23, the connection between the standing wall 74c and the cutting blade holding member 25c is reinforced by the reinforcing rib 32c on the upper surface of the cutting member 7c, and the cutting blade 24c and the cutting blade holding member 25c are formed on the lower surface of the cutting member 7c. The standing wall 74c and the finger hook member 26c are reinforced by the reinforcing ribs 33c and 34c.
As shown in FIG. 25, two types of stopper structures, that is, a passage prevention stopper structure 75c and a return prevention stopper structure 76c are provided between the cutting member 7c and the perforation 22c.
The passage preventing stopper structure 75c is provided with a plate-like stopper piece 77c projecting laterally from the finger hook member 26c at the base end portion of the incising member 7c. A reinforcing rib 78c is provided between the finger hook member 26c and the stopper piece 77c to connect and reinforce them.
When the incising member 7c is pushed into the perforation 22c as an incising operation, it is a stopper structure for preventing the incising member 7c from excessively passing the perforation 22c and entering the cup-type container, and a return preventing stopper structure 76c. On the contrary, the cutting member 7c pushed into the perforation 22c does not stop in the perforation 22c due to the elastic recovery of the hinge 10c, and does not return to the original direction from the perforation 22c. It is a stopper structure to prevent it.
In the passage preventing stopper structure 75c, the stopper 82c protrudes from the side surface 8c of the raised portion 23c facing the perforation 22c toward the inside of the perforation 22c. In the return prevention stopper structure 76c, the stopper 83c extends from the same side surface 81c to the inside of the perforation 22. Protrusively toward.
Both of these stoppers 82c and 83c protrude to a position where they interfere with the finger hook member 26 when the finger hook member 26 enters the perforation 22c as an incision operation.
The stopper 82c for preventing passage has a large protruding amount from the side surface 81c of the raised portion 23c, a large thickness, and a large rigidity. Therefore, even when the stopper 82c abuts on the stopper piece 77c of the incising member 7c, the stopper piece Since 77c does not get over the stopper 82c, the movement of the cutting member 7c is stopped at a position coinciding with the perforation 22c. On the other hand, the stopper 83c of the return prevention stopper structure 76c has a small protrusion amount, a small thickness, a small rigidity, and a structure that easily causes elastic bending. Therefore, when the cutting member 7c is incised, When the stopper piece 77c comes into contact with the stopper 83c for preventing return, the stopper 83c can be elastically bent so as to get over the return preventing stopper 76c and reach the position coincident with the perforation 22, but in this case, the stopper structure for preventing return is provided. Since 76c is elastically restored to its original state, the restored stopper 76c abuts against the stopper piece 77c of the cutting member 7c to prevent the cutting member 7c from returning and returning.

図２６に示すように、切開部材７の指掛り部材２６ｃを指標３１ｃに従って指で押し上げると、指掛り部材２６ｃ及びこれと一体となった切刃２４ｃがヒンジ１０ｃの周りに回転して下降し、切刃２４ｃがシール蓋５を切開して流出口２８ｃが開口する。指掛り部材２６ｃが穿孔２２ｃの高さと一致すると指掛り部材２６ｃが穿孔２２ｃの縁のストッパーに８２ｃ、８３ｃに拘束されて姿勢を保持し、流出口２８ｃの開口が終了する。この状態でカップ型容器を口元で傾けると、内容液は流出口２８ｃから流出し、穿孔２２ｃの縁と指掛り部材２６ｃの外縁との間の隙間４２ｃを通して注出され、飲むことができる。   As shown in FIG. 26, when the finger hook member 26c of the incising member 7 is pushed up with the finger according to the index 31c, the finger hook member 26c and the cutting blade 24c integrated with the finger hook member 26c rotate around the hinge 10c and descend, The cutting blade 24c incises the seal lid 5, and the outflow port 28c opens. When the finger hook member 26c coincides with the height of the perforation 22c, the finger hook member 26c is restrained by the stoppers 82c and 83c at the edge of the perforation 22c to maintain the posture, and the opening of the outflow port 28c is completed. When the cup-shaped container is tilted at the mouth in this state, the content liquid flows out from the outflow port 28c and is poured out through the gap 42c between the edge of the perforation 22c and the outer edge of the finger hook member 26c and can be drunk.

このオーバーキャップ１ｃでもシール蓋を切開する切開部材を有するが、その切開部材は刃部材の他に、刃部材に固定した指掛り部材を有するので、刃部材の操作が容易であり、ひいては飲み口、空気孔の形成が容易である。切開部材はオーバーキャップ本体と一体であるのでオーバーキャップの構造が簡単になる。オーバーキャップは上方に立ち上がった流出案内壁を有するので、それが飲用時のマウスピースとして機能し、内容物の飲用がきわめて容易である。また切開部材に固定している指掛り部材が所定の角度に傾いているので、使用者は指掛り部材を押し倒す方向を推測し理解することが容易であり、シール蓋の切開操作が容易である。
また、指掛り部材の倒れ角度は９０°以下であるので、指掛り部材の押し倒しの方向を指す機能を発揮する。
また、指掛り部材に視認可能または触認可能な指標が設けられるので、操作の内容を一層明確に理解させることができる。この場合指掛り部材自体が一定角度で傾斜していて、指標が設けられた指掛り部材の側面が上から良く見えるので、操作内容の理解が一定確実である。
さらに、切刃保持部材を指掛り部材が覆うことになり、上からは指掛り部材しか見えないので、必要な動作の過程を単純化して操作者に理解させることができて操作者に不安を与えることがない。
そのうえ、ストッパー片が穿孔の縁から内方に張り出していて穿孔に達した指掛り部材と干渉するので、指掛り部材が穿孔と面一になる位置が確保され、内容物の流出口の形状が一定で安定した状態となるので、内容物の注出流が安定する。
しかも、流出案内壁がシングルウォール構造となっているので、飲み口としての口当りが良好となり、また、注出時の液溜めの発生を防止することができる。
また、流出案内壁の内側壁面は外側にあるために、内側壁面が樋状となり、内容物の飲用が円滑である。 The overcap 1c also has an incision member for incising the seal lid. However, since the incision member has a finger hook member fixed to the blade member in addition to the blade member, the operation of the blade member is easy, and as a result, the drinking mouth The formation of air holes is easy. Since the cutting member is integral with the overcap body, the structure of the overcap is simplified. Since the overcap has an outflow guide wall that rises upward, it functions as a mouthpiece when drinking, and it is extremely easy to drink the contents. In addition, since the finger hook member fixed to the incision member is inclined at a predetermined angle, the user can easily guess and understand the direction in which the finger hook member is pushed down, and the incision operation of the seal lid is easy. .
In addition, since the tilt angle of the finger hook member is 90 ° or less, the function of pointing the direction of pushing down the finger hook member is exhibited.
Further, since a visible or tactile indicator is provided on the finger hook member, the contents of the operation can be understood more clearly. In this case, the finger hook member itself is inclined at a constant angle, and the side surface of the finger hook member provided with the index can be clearly seen from above, so that the understanding of the operation content is certain.
Furthermore, since the finger hook member covers the cutting blade holding member and only the finger hook member can be seen from above, it is possible to simplify the process of necessary operations and make the operator understand and to make the operator uneasy. Never give.
In addition, since the stopper piece protrudes inward from the edge of the perforation and interferes with the finger hook member that has reached the perforation, a position where the finger hook member is flush with the perforation is secured, and the shape of the outlet of the contents is Since it is in a constant and stable state, the content flow is stabilized.
In addition, since the outflow guide wall has a single wall structure, the mouth feel as a drinking mouth is good, and the occurrence of a liquid reservoir during pouring can be prevented.
Moreover, since the inner wall surface of the outflow guide wall is on the outer side, the inner wall surface has a bowl-like shape, and the contents can be consumed smoothly.

図２７から図２９は第４、第５及び第６の実施例に係るオーバーキャップ１ｄ、１ｅ、１ｆが示されている。
これらのオーバーキャップ１ｄ、１ｅ、１ｆに共通する特徴は覆部１１の筒状の周壁１５が中心線１４周りの全周長にわたって等高である点と、穿孔２２の側縁から内方に張り出すストッパー片４１の幅を大きくして穿孔２２に達した指掛り部材２６ｄ、２６ｅ、２６ｆと干渉して指掛り部材２６ｄ、２６ｅ、２６ｆが穿孔２２を通り抜けてカップ型容器２側に入り込むのを防止する機能を確実にした点にある。 27 to 29 show overcaps 1d, 1e, and 1f according to the fourth, fifth, and sixth embodiments.
The features common to these overcaps 1d, 1e, and 1f are that the cylindrical peripheral wall 15 of the cover portion 11 is level over the entire circumference around the center line 14, and stretches inward from the side edge of the perforation 22. When the width of the stopper piece 41 to be extended is increased and the finger hook members 26d, 26e, 26f that have reached the perforation 22 interfere with each other, the finger hook members 26d, 26e, 26f pass through the perforation 22 and enter the cup-shaped container 2 side. It is in the point which secured the function to prevent.

以上の説明から明らかな通りこの発明によれば、流出口や空気孔の形成が容易で、構造も簡単であり、購買者が切開部材の構造を見ただけで、その操作方法も推測し、理解し易いオーバーキャップを得ることができる。   As is clear from the above description, according to the present invention, the formation of the outlet and the air hole is easy, the structure is simple, and the purchaser just looks at the structure of the incision member, and also estimates the operation method, An overcap that is easy to understand can be obtained.
