Description

【0001】
【発明の属する技術分野】
本発明は、例えば牛乳瓶等の飲料用容器に用いるキャップに係り、開封が容易で、再封も確実に行える飲料容器用キャップに関する。
【0002】
【従来の技術】
牛乳瓶などに使用する蓋体の改良として、例えば、特開平11−70964号公報に記載された天板付キャップシールなどが提案されている。このキャップシールは、瓶の開口部に落とし込んだ蓋体の上に、更に天板を設け、この天板と開口部とをシール材で被覆したものである。
【0003】
一方、一旦開封した蓋体を再びもとの容器に施蓋できるようにした蓋体として特開平9−47485号公報に記載された薬用瓶の蓋が提案されている。この蓋体は、逆有底円筒状に形成した口金と、その口金内に装着する合成樹脂製の蓋板との組合せとし、蓋板の上面部分が口金の頂面から露出するように構成したものである。
【0004】
【発明が解決しようとする課題】
牛乳瓶に使用されていた従来の蓋体は、専ら飲み切りサイズの瓶に使用されており、開口部をシール等で被覆するようにしている。このようなシール等を用いた蓋体では、一度シールを剥がしてしまうと再封はできないので、瓶の開口部が露出するものであった。ところが、生活スタイルの多様化と共に、どのようなサイズの瓶でも再封可能な蓋体が望まれる傾向になってからは、牛乳瓶などの飲料容器用の蓋体にも再封可能な蓋体が望まれるようになっている。
【0005】
一方、再封可能な蓋体として開発された後者の薬用瓶の蓋は、蓋体の外周に捲き付けている口金を切り取って外した後に、蓋体を開封する構造を採用している。そのため、口金を取り外す作業が煩わしく、薬用瓶の蓋として好適であっても、飲料容器の蓋として採用するには、きわめて扱い難い構造になっている。特に、飲料容器に用いる蓋は、老人や子供でも容易に扱える構造が望まれる。
【0006】
そこで本発明は上述の課題を解消すべく創出されたもので、開封が容易で、再封も確実に行える飲料容器用キャップの提供を目的とするものである。
【0007】
【課題を解決するための手段】
上述の課題を解消するため本発明の第1の手段は、瓶Pの口部外周に外嵌する側壁部1と瓶Pの口部上端面に密着する天板2とを一体に形成し、口部外周に嵌合係止する係止突部1Aを側壁部1に設け、口部内周縁に嵌合する嵌合片2Aを天板2の下面に突設した飲料容器用キャップにおいて、側壁部1の前面一部に指掛け用の係止突起3を設け、前記側壁部1を縦方向に切り離す一対の縦弱化ライン1Bを係止突起3の両がわに設け、該縦弱化ライン1Bの各上端部から口部の外周縁に沿って天板2を横方向に切り離す一対の横弱化ライン2Bを設けたことにある。
【0008】
第2の手段における縦弱化ライン1Bは、前記係止突起3の中央部を中心とする左右対称の位置で、該中心から夫々60°〜75°の角度を成す位置に形成したものである。
【0009】
第3の手段の横弱化ライン2Bは、天板2の中心より前記縦弱化ライン1Bに至る仮想線から、前記側壁部1の後面方向に夫々30°〜45°の角度に至る範囲で形成することを課題解消のための手段とする。
【0010】
本発明によると、係止突起3を指で押し上げると、側壁部1の縦弱化ライン1Bが切り離される。更に、切り離された側壁部1を持ち上げると、天板2の横弱化ライン2Bが切り離され、瓶Pの係止溝部P1から蓋体が外れることになる。再封する場合は、天板2の嵌合片2Aを口部内周縁に嵌合すると共に、側壁部1の係止突部1Aを瓶Pの係止溝部P1に係合させることで、縦弱化ライン1Bや横弱化ライン2Bが切り離されていても、もとの状態に再封することができる。
【0011】
【発明の実施の形態】
以下、図面に基づいて本発明の実施の形態を説明する。
【0012】
本発明キャップは、軟質性の合成樹脂によって形成されるもので、瓶Pの口部外周に外嵌する側壁部1と、瓶Pの口部上端面に密着する天板2とを一体に形成したものである(図1参照)。
【0013】
側壁部1の内周面に、係止突部1Aを突設している。この係止突部1Aは、瓶Pの口部外周に嵌合係止する(図2参照)。図示の係止突部1Aは、係止溝部P1に嵌合する一条の係止突部1Aを示しているが、係止溝部P1の数によって係止突部1Aの数も任意に増やすことができる。また、係止溝部P1に嵌合する代わりに、口部の張り出した側面下端部に係止する係止突部1Aを使用することも可能である(図示せず)。
【0014】
側壁部1の前面一部に設けた係止突起3は、キャップを開ける際の指掛け用として使用する。そしてこの係止突起3の両がわに一対の縦弱化ライン1Bを設けている。
【0015】
縦弱化ライン1Bは、側壁部1を縦方向に切り離すように、薄肉状に形成したもので、天板2中央から係止突起3の中央部に至る線を中心線Xとし、この中心線Xの左右対称の位置に設ける。最適な位置は、該中心線Xから夫々60°〜75°の角度を成す位置とする(図3参照)。図示の縦弱化ライン1Bは、中心線Xから夫々75°の角度を成す位置に設けている。この位置に設けることで、縦弱化ライン1Bを切り離す際に、最も少ない荷重で切り離すことが可能になる。また、中心線Xから夫々75°を超える場合は、縦弱化ライン1Bが切り離されず、最終的に過大な荷重によってキャップが外れてしまうことがわかる(表1参照)。
【0016】
【表1】

Figure 2004026208
表1は、本発明キャップにおける縦弱化ラインと横弱化ラインとの破断テストの結果を示したものである。このテストは、左右の縦弱化ライン1Bの角度を4段階に分けて実施し、瓶Pに装着したキャップの係止突起3を持ち上げた際に、夫々の縦弱化ライン1Bが何kgで破断するかを測定した。尚、実施角度は、左右の縦弱化ライン1B相互の角度になっているので、中心線Xから各横弱化ライン2Bに至る角度の二倍になっている。
【0017】
この結果、縦弱化ライン1B相互を120°(中心線Xから60°)に設定したときに、平均1.1kgで破断し、150°(中心線Xから75°)に設定したときに、平均0.93kgで破断した。また、180°(係止突起3の中心から90°)以上に設定すると、縦弱化ライン1Bが切り離されず、最終的にキャップが外れてしまった。尚、縦弱化ライン1B相互を120°以内に設定した場合は、この縦弱化ライン1Bから後述する横弱化ライン2Bを切り離す距離が長くなるので、キャップの取り外し操作上、適当でないとして予め除外している。
【0018】
天板2の下面に、口部内周縁に嵌合する嵌合片2Aを突設する(図2参照)。この嵌合片2Aは、キャップを再封する際に、瓶Pの口部を密封するものであるから、嵌合力が強くなる程、密封力を高めることができる。図示の嵌合片2Aは先端にテーパー2Aaを設けて嵌合し易くしている。また、嵌合片2Aの形状は再封時に口部を密封できればよく、その形状は任意に変更することができる。
【0019】
横弱化ライン2Bは、天板2に設けた薄肉状のラインで、前述した縦弱化ライン1Bの各上端部から口部の外周縁に沿って切り離すように一対設けている。この横弱化ライン2Bは、天板2の中心より前記縦弱化ライン1Bに至る仮想線Yから、前記側壁部1の後面方向に夫々30°〜45°の角度に至る範囲で形成する(図3参照)。図示の横弱化ライン2Bは、仮想線Yから夫々30°に至る範囲で形成している。この角度は、前記縦弱化ライン1Bの最適角度(最も弱い力で切り離すことが可能な中心線Xから75°の角度)と組み合わせることによって、最も短い距離で天板2の直径部分前後を効果的に切断できるので、横弱化ライン2Bとして最適な角度になっている。
【0020】
また、横弱化ライン2Bが切り離されると、本発明キャップにおける直径部分と該直径部分の前後とが切り離されるので、取り外したキャップを容易に再封することができる。すなわち、切り離されたキャップ前面がわと、後面がわとの各嵌合片2Aを口部内側面に別々に嵌合することができるから、一方の嵌合片2Aを嵌合すると、その後は、天板2を押し込むだけで残りの嵌合片2Aを簡単に再封する事ができる(図4(ハ)参照)。したがって、嵌合片2Aの密封力を高めるために、嵌合片2Aの嵌合力を強く設定しても容易に再封できる利点がある。
【0021】
尚、縦弱化ライン1Bの角度を中心線Xから60°に設定した場合は、この横弱化ライン2Bの設定範囲は、仮想線Yから45°に至る範囲に設定するものである(図示せず)。更に、これら縦弱化ライン1B、横弱化ライン2Bの角度設定はキャップの材質やサイズ等の変更により、前記範囲内で適宜変更することができる。
【0022】
図4(イ)乃至(ハ)は、本発明キャップの開閉操作を示している。すなわち同図(イ)は、係止突起3に親指を掛けて持ち上げ、縦弱化ライン1Bから横弱化ライン2Bを順次切り離している状態を示している。また、同図(ロ)は、本発明キャップを瓶Pの口部から取り外した状態、又は、取り外したキャップを口部に再封する状態を示す。そして、同図(ハ)は、嵌合片2Aを口部内周縁に嵌合させている状態を示している。
【0023】
【発明の効果】
本発明は上述の如く構成したことにより当初の目的を達成した。
【0024】
すなわち、側壁部1の前面一部に指掛け用の係止突起3を設け、前記側壁部1を縦方向に切り離す一対の縦弱化ライン1Bと、該縦弱化ライン1Bの各上端部から口部の外周縁に沿って天板2を横方向に切り離す一対の横弱化ライン2Bとを設けたことにより、係止突起3に指を掛けて上方へ持ち上げることで、縦弱化ライン1Bと横弱化ライン2Bとを簡単に切り離すことができるので、蓋を開口する操作が極めて容易になる。
【0025】
また、口部外周に嵌合係止する係止突部1Aを側壁部1に設け、該口部内周縁に嵌合する嵌合片2Aを天板2の下面に突設しているので、再封する場合は、天板2の嵌合片2Aを口部内周縁に嵌合することで、瓶Pを再び密封することができる。この結果、収納物がこぼれるおそれがなくなり、また、瓶Pの口部も側壁部1によって保護される。
【0026】
更に、縦弱化ライン1Bは、前記係止突起3の中央部を中心とする左右対称の位置で、該中心から夫々60°〜75°の角度を成す位置に形成したことにより、縦弱化ライン1Bを切り離す際に大きな力は必要なく、老人や子供でも容易に切り離すことが可能である。
【0027】
また、横弱化ライン2Bは、天板2の中心より前記縦弱化ライン1Bに至る仮想線から、前記側壁部1の後面方向に夫々30°〜45°の角度に至る範囲で形成しているので、縦弱化ライン1Bに続けて横弱化ライン2Bを切り離す作業も極めて簡単に行える。このように、縦弱化ライン1Bから横弱化ライン2Bまでを切り離した後は、瓶Pの係止溝部P1に嵌合している係止突部1Aを大幅に開放することができるので、老人や子供でも本発明キャップを極めて容易に外すことができる。
【0028】
しかも、横弱化ライン2Bが切り離されると、本発明キャップにおける直径部分と該直径部分の前後とが切り離されるので、取り外したキャップを容易に再封することができる。このように、キャップを開封した後でも簡単且つ確実に再封できるので、飲み切りサイズの瓶から容量の大きな瓶に至るまで使用することが可能になり、汎用性に富むものである。
【0029】
このように、本発明によると、老人や子供でも容易に取り扱うことができ、再封も確実に行えるなどといった種々の効果を奏するものである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cap used for a beverage container such as a milk bottle, for example, and relates to a cap for a beverage container that can be easily opened and can be securely resealed.
[0002]
[Prior art]
As an improvement of a lid used for a milk bottle or the like, for example, a cap seal with a top plate described in JP-A-11-70964 has been proposed. In this cap seal, a top plate is further provided on a lid dropped into the opening of the bottle, and the top plate and the opening are covered with a sealing material.
[0003]
On the other hand, a lid for a medicinal bottle described in Japanese Patent Application Laid-Open No. 9-47485 has been proposed as a lid in which the lid once opened can be covered again with the original container. This lid was a combination of an inverted bottomed cylindrical base and a synthetic resin cover attached to the base, and the upper surface of the cover was exposed from the top of the base. Things.
[0004]
[Problems to be solved by the invention]
The conventional lid used for a milk bottle is exclusively used for a bottle of a drinkable size, and the opening is covered with a seal or the like. In a lid using such a seal or the like, since the seal cannot be resealed once the seal is peeled off, the opening of the bottle is exposed. However, with the diversification of lifestyles and the tendency for lids that can be resealable in bottles of any size to be desired, lids for beverage containers such as milk bottles can also be resealable. Is becoming desirable.
[0005]
On the other hand, the lid of the latter medicinal bottle developed as a resealable lid adopts a structure in which a base wound around the outer periphery of the lid is cut off and removed, and then the lid is opened. Therefore, the operation of removing the base is troublesome, and even if it is suitable as a lid for a medicinal bottle, it has a structure that is extremely difficult to handle when adopted as a lid for a beverage container. In particular, a lid used for a beverage container is desired to have a structure that can be easily handled by elderly people and children.
[0006]
Then, this invention was created in order to solve said subject, and it aims at provision of the cap for beverage containers which can be easily opened and can be resealed reliably.
[0007]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a first means of the present invention is to integrally form a side wall portion 1 fitted on the outer periphery of the mouth of the bottle P and a top plate 2 which is in close contact with the upper end surface of the mouth of the bottle P, In the beverage container cap, a locking projection 1A that fits and locks on the outer periphery of the mouth is provided on the side wall 1 and a fitting piece 2A that fits on the inner peripheral edge of the mouth protrudes from the lower surface of the top plate 2. A locking projection 3 for hooking a finger is provided on a part of the front face of the front projection 1, and a pair of longitudinal weakening lines 1 B for vertically separating the side wall 1 are provided on both sides of the locking projection 3. There is provided a pair of lateral weakening lines 2B for separating the top board 2 laterally from the upper end along the outer peripheral edge of the mouth.
[0008]
The vertical weakening lines 1B in the second means are formed at symmetrical positions centered on the center of the locking projection 3 and at angles of 60 ° to 75 ° from the center, respectively.
[0009]
The horizontal weakening line 2B of the third means is formed in a range from an imaginary line extending from the center of the top plate 2 to the vertical weakening line 1B to an angle of 30 ° to 45 ° in the rear direction of the side wall portion 1 respectively. This is a means for solving the problem.
[0010]
According to the present invention, when the locking projection 3 is pushed up with a finger, the longitudinal weakening line 1B of the side wall 1 is cut off. Further, when the separated side wall portion 1 is lifted, the lateral weakening line 2B of the top plate 2 is separated, and the lid comes off from the locking groove P1 of the bottle P. In the case of resealing, the fitting piece 2A of the top plate 2 is fitted to the inner peripheral edge of the mouth, and the locking projection 1A of the side wall 1 is engaged with the locking groove P1 of the bottle P, thereby weakening the longitudinal direction. Even if the line 1B or the lateral weakening line 2B is cut off, it can be resealed to its original state.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
The cap of the present invention is made of a soft synthetic resin. The cap 1 is integrally formed with a side wall 1 that is fitted around the outer periphery of the mouth of the bottle P and a top plate 2 that is in close contact with the upper end surface of the mouth of the bottle P. (See FIG. 1).
[0013]
On the inner peripheral surface of the side wall 1, a locking projection 1 </ b> A protrudes. The locking projection 1A fits and locks on the outer periphery of the mouth of the bottle P (see FIG. 2). The illustrated locking projection 1A shows a single locking projection 1A that fits into the locking groove P1, but the number of locking projections 1A may be arbitrarily increased according to the number of locking grooves P1. it can. Instead of fitting into the locking groove P1, it is also possible to use a locking projection 1A that locks to the lower end of the side surface where the mouth protrudes (not shown).
[0014]
The locking projection 3 provided on a part of the front surface of the side wall portion 1 is used for hanging a finger when opening the cap. A pair of longitudinal weakening lines 1B are provided on both sides of the locking projection 3.
[0015]
The vertical weakening line 1B is formed in a thin shape so as to cut off the side wall 1 in the vertical direction. A line from the center of the top plate 2 to the center of the locking projection 3 is defined as a center line X. At symmetrical positions. The optimal position is a position that forms an angle of 60 ° to 75 ° from the center line X (see FIG. 3). The illustrated vertical weakening lines 1B are provided at positions each forming an angle of 75 ° from the center line X. By providing at this position, it becomes possible to separate the vertical weakened line 1B with the least load. In addition, when each exceeds 75 ° from the center line X, it can be seen that the longitudinal weakening line 1B is not separated, and the cap eventually comes off due to an excessive load (see Table 1).
[0016]
[Table 1]
Figure 2004026208
Table 1 shows the results of a fracture test of the vertical weakening line and the horizontal weakening line in the cap of the present invention. This test is performed by dividing the angle of the left and right vertical weakening lines 1B into four stages, and when lifting the locking projections 3 of the cap attached to the bottle P, each kg of each vertical weakening line 1B breaks. Was measured. In addition, since the implementation angle is the angle between the left and right vertical weakening lines 1B, it is twice the angle from the center line X to each horizontal weakening line 2B.
[0017]
As a result, when the longitudinal weakening lines 1B were set at 120 ° (60 ° from the center line X), the fracture occurred at an average of 1.1 kg, and when set at 150 ° (75 ° from the center line X), the average It broke at 0.93 kg. Further, when the angle was set to 180 ° or more (90 ° from the center of the locking projection 3), the vertical weakening line 1B was not cut off, and the cap eventually came off. If the vertical weakening lines 1B are set to each other within 120 °, a distance for separating a horizontal weakening line 2B described later from the vertical weakening line 1B becomes long. I have.
[0018]
On the lower surface of the top plate 2, a fitting piece 2A fitted to the inner peripheral edge of the mouth is protruded (see FIG. 2). Since the fitting piece 2A seals the mouth of the bottle P when the cap is resealed, the sealing force can be increased as the fitting force increases. The fitting piece 2A shown is provided with a taper 2Aa at the tip to facilitate fitting. Also, the shape of the fitting piece 2A may be any shape as long as the mouth can be sealed at the time of resealing, and the shape can be arbitrarily changed.
[0019]
The horizontal weakening line 2B is a thin line provided on the top plate 2 and is provided in a pair so as to be separated from each upper end of the above-described vertical weakening line 1B along the outer peripheral edge of the mouth. The horizontal weakening line 2B is formed in a range from an imaginary line Y extending from the center of the top plate 2 to the vertical weakening line 1B to an angle of 30 ° to 45 ° toward the rear surface of the side wall 1 (FIG. 3). reference). The illustrated horizontal weakening lines 2B are respectively formed in a range extending from the virtual line Y to 30 °. By combining this angle with the optimum angle of the longitudinal weakening line 1B (the angle of 75 ° from the center line X that can be cut off with the weakest force), the front and rear diameters of the top plate 2 can be effectively reduced at the shortest distance. The angle is optimal as the lateral weakening line 2B.
[0020]
Further, when the lateral weakening line 2B is cut off, the diameter portion of the cap of the present invention and the front and rear portions of the diameter portion are cut off, so that the removed cap can be easily resealed. That is, since the fitting pieces 2A of the separated cap front and back faces can be separately fitted to the inner surface of the mouth, when one fitting piece 2A is fitted, thereafter, The remaining fitting piece 2A can be easily resealed simply by pushing the top plate 2 (see FIG. 4C). Therefore, there is an advantage that even if the fitting force of the fitting piece 2A is set to be high in order to increase the sealing force of the fitting piece 2A, the sealing can be easily performed again.
[0021]
When the angle of the vertical weakening line 1B is set to 60 ° from the center line X, the setting range of the horizontal weakening line 2B is set to a range from the virtual line Y to 45 ° (not shown). ). Further, the angle setting of the vertical weakening line 1B and the horizontal weakening line 2B can be appropriately changed within the above range by changing the material and size of the cap.
[0022]
FIGS. 4A to 4C show opening and closing operations of the cap of the present invention. That is, FIG. 2A shows a state in which the locking projection 3 is lifted with a thumb and the horizontal weakening line 2B is sequentially separated from the vertical weakening line 1B. FIG. 2B shows a state in which the cap of the present invention is removed from the mouth of the bottle P, or a state in which the removed cap is resealed in the mouth. FIG. 3C shows a state in which the fitting piece 2A is fitted to the inner peripheral edge of the mouth.
[0023]
【The invention's effect】
The present invention has achieved the initial object by being configured as described above.
[0024]
That is, a locking projection 3 for hooking a finger is provided on a part of the front surface of the side wall portion 1, and a pair of vertical weakening lines 1 B for separating the side wall portion 1 in the vertical direction, and from the upper end of the vertical weakening line 1 B to the mouth. By providing a pair of lateral weakening lines 2B for separating the top plate 2 in the horizontal direction along the outer peripheral edge, a finger is placed on the locking projection 3 and lifted upward, so that the vertical weakening line 1B and the horizontal weakening line 2B are provided. Can be easily separated, so that the operation of opening the lid becomes extremely easy.
[0025]
In addition, a locking projection 1A that fits and locks on the outer periphery of the mouth is provided on the side wall portion 1 and a fitting piece 2A that fits on the inner peripheral edge of the mouth protrudes from the lower surface of the top plate 2, so that In the case of sealing, the bottle P can be sealed again by fitting the fitting piece 2A of the top plate 2 to the inner peripheral edge of the mouth. As a result, there is no danger of spilling of stored items, and the mouth of the bottle P is protected by the side wall 1.
[0026]
Further, the vertical weakening lines 1B are formed at positions symmetrical with respect to the center of the locking projections 3 at right and left sides and at angles of 60 ° to 75 ° from the centers, respectively. It does not require great force when separating, and can be easily separated by elderly people or children.
[0027]
Further, the horizontal weakening line 2B is formed in a range from an imaginary line extending from the center of the top plate 2 to the vertical weakening line 1B to an angle of 30 ° to 45 ° in the direction of the rear surface of the side wall 1 respectively. Also, the operation of separating the horizontal weakening line 2B following the vertical weakening line 1B can be performed very easily. As described above, after disconnecting the vertical weakening line 1B from the horizontal weakening line 2B, the locking projection 1A fitted to the locking groove P1 of the bottle P can be largely opened, so that the elderly or the elderly can be opened. Even a child can remove the cap of the present invention very easily.
[0028]
Moreover, when the lateral weakening line 2B is cut off, the diameter portion of the cap of the present invention and the front and rear portions of the diameter portion are cut off, so that the removed cap can be easily resealed. As described above, since the cap can be easily and reliably re-sealed even after the cap is opened, it can be used from a bottle of a full size to a large-capacity bottle, which is versatile.
