Description
本発明は、飲料や調味料、薬品等の内容液を収容する容器の開封具に関し、より具体的には注出口がシール部材により封止され、且つそのシール部を取り囲むように上方に延びる注出筒が形成されている容器に対して好適な開封具に関する。 The present invention relates to an opening device for a container that contains a liquid such as beverages, seasonings, and medicines, and more specifically, a spout is sealed by a seal member and extends upward so as to surround the seal portion. The present invention relates to an opening device suitable for a container in which a delivery tube is formed.
小容量の紙パック容器に収容されている飲料などを飲む際、容器の注出口のシールをストローを突き刺して破断する場合に、内容液が飛散することがある。そのため、このような容器として、例えば容器上端の一部に注出部を形成し、この注出部に付属のストローを突き刺して容器の注出口のシールを破断することが行われているが、ストローの強度が弱く、シールへの突き刺しに失敗することもあった。そこで、内容液が収容された容器を開封するに際し、シール破断用の開封具が提案されている。 When drinking a beverage or the like contained in a small-capacity paper pack container, the content liquid may scatter when the seal at the spout of the container is punctured with a straw. Therefore, as such a container, for example, a pouring part is formed at a part of the upper end of the container, and a stick attached to the pouring part is pierced to break the seal of the pouring outlet of the container. The strength of the straw was so weak that it sometimes failed to pierce the seal. Therefore, when opening a container in which the content liquid is stored, an opening tool for breaking the seal has been proposed.
このような開封具に関し、例えば、特許文献１には、注ぎ口とキャップとからなる容器用蓋部材において、紙製容器本体に注ぎ口を粘着シートを介在させて着脱可能に貼着し、注ぎ口又はキャップの何れか一方に容器本体に穴を穿設する尖部を一体形成した開封具が記載されている。 With regard to such an opening tool, for example, in Patent Document 1, in a container lid member composed of a spout and a cap, the spout is attached to the paper container body detachably with an adhesive sheet interposed between the pour spout and the cap. An opening device is described in which a pointed portion for forming a hole in a container body is integrally formed on either the mouth or the cap.
しかしながら、特許文献１に記載の開封具の構造では、キャップと尖部とにより容器本体に注出口を形成することになるため、手で摘み難く開封時の力が伝わりにくいといった問題を有する。また、注出口やキャップの径が小さい場合には、容器の注ぎ口に尖部を突き刺して穴を穿設後に、キャップをねじってキャップと尖部を注ぎ口から取り外すのが容易ではないという問題点がある。 However, the structure of the opening device described in Patent Document 1 has a problem in that the cap and the cusp form a spout in the container body, so that it is difficult to pick by hand and the force at the time of opening is difficult to be transmitted. Also, when the diameter of the spout or cap is small, it is not easy to remove the cap and the tip from the spout by twisting the cap after piercing the spout into the spout of the container and making a hole There is a point.
本発明は、このような従来の課題を解決するためになされたもので、シール部が形成されている容器のシール部を突き刺して破断するに際して、使用者の手の力が入り易い形状を備え、しかも開封及び取り外し操作のし易い開封具を提供することを目的とする。
また、本発明の他の目的は、容器のリシールの際に、内容液の漏洩がなく、容器からの抜けを防止できる開封具を提供することである。
The present invention has been made in order to solve such a conventional problem, and has a shape in which the force of the user's hand can easily enter when the seal portion of the container in which the seal portion is formed is pierced and broken. And it aims at providing the opening tool which is easy to open and remove.
Another object of the present invention is to provide an opening device that prevents leakage of the content liquid and prevents the container from coming off when the container is resealed.
（１）本発明の開封具は、容器の注出口を封止するシール部を囲繞し上方に延びる注出筒が形成されている容器の該シール部を破断するための開封具であって、容器の注出筒に挿入する筒状部と、該筒状部の上端を塞ぐ天蓋からなり、該天蓋は注出筒上端面を完全に覆う大きさを有し、該天蓋の上面には、前記筒状部の径方向に延びる基部と該基部の両側から前記筒状部の外壁に沿って下方に延伸した延長部とからなる摘み部が設けられており、前記筒状部は、その下端が容器のシール部を破断するために斜めに切断されて尖った形状となっており、前記両延長部間の距離は、前記注出筒外径より大きく形成されていることを特徴とする。 (1) The opening tool of the present invention is an opening tool for breaking the seal portion of the container in which a pouring tube is formed surrounding the seal portion that seals the spout of the container and extending upward, It consists of a cylindrical part to be inserted into the dispensing cylinder of the container, and a canopy that closes the upper end of the cylindrical part, and the canopy has a size that completely covers the upper end surface of the dispensing cylinder. A knob portion comprising a base portion extending in the radial direction of the cylindrical portion and an extension portion extending downward from both sides of the base portion along the outer wall of the cylindrical portion is provided, and the cylindrical portion has a lower end thereof In order to break the seal part of the container, it is cut obliquely and has a pointed shape, and the distance between the two extension parts is formed larger than the outer diameter of the extraction cylinder.

The lower outer peripheral surface is provided with a protrusion that is inserted into the container and then locked to the inner wall of the container to prevent the tubular portion from coming off.
本発明の開封具によれば、天蓋の上面に設けられた延長部を含む摘み部を摘むか或いは、摘み部を含む天蓋を上方から押圧することで、使用者が容器のシール部を突き刺して破断するに際して確実に力を伝達することができ、その結果として容易に容器の開封を行うことができ、しかも、摘み部を摘んで開封具の取り外しも容易に行うことができる。
また、容器の注出筒を跨ぐ両延長部間の距離が注出筒外径より若干大きいので、開封具を容器の注出筒に挿入する際に、この延長部がガイドとなりスムーズに挿入操作を行うことができる。
また、インナーリングによりシール部破断後のリシールを行うことができるにも拘わらず、摘み部を摘むことにより、容易に開閉の操作を行うことができ、さらに筒状部下方外周面の突起により、リシール時に開封具と注出筒との係止力が向上するので、容器の転倒程度では注出筒から開封具が外れ、注出筒より誤って内容液が排出されることはない。
According to the opening device of the present invention, the user can pierce the seal portion of the container by picking the knob including the extension provided on the upper surface of the canopy or pressing the canopy including the knob from above. The force can be reliably transmitted when it breaks, and as a result, the container can be easily opened, and the unsealing tool can be easily removed by picking the knob.
In addition, since the distance between the two extension parts straddling the container's dispensing cylinder is slightly larger than the outer diameter of the container, this extension serves as a guide when inserting the opening tool into the container's dispensing cylinder. It can be performed.
In addition, although the inner ring can be resealed after breaking the seal part, it can be easily opened and closed by picking the knob part, and further by the protrusion on the lower outer peripheral surface of the cylindrical part, Since the locking force between the opening tool and the dispensing cylinder is improved at the time of resealing, the opening tool is removed from the dispensing cylinder when the container is overturned, and the content liquid is not accidentally discharged from the dispensing cylinder.

Then, the seal portion is broken and opened by the lower end of the cylindrical portion 23, and the inner ring 31 of the opening tool 3 is brought into close contact with the inner peripheral surface 232 of the cylindrical portion 23 and sealed. At this time, the protrusion 32 of the cylindrical portion 23 is locked to the inner wall 24 of the container 2, and the unsealing of the opening tool 3 from the container 2 is prevented.
また、突起３２の高さ（厚み）と筒状部１１の外径とを合わせた径Ｃは、インナーリング３１の外径Ｄよりも小さくなるように設定している。これにより、筒状部１１を注出筒２３へ挿入する際において、突起３２が注出筒の内周面２３２と干渉することを防止できる。このように実施例２の開封具３は、インナーリング３１と突起３２とを備えたことにより、封止部材としてのキャップの機能をも兼ね備えることができる。 The diameter C, which is the sum of the height (thickness) of the protrusion 32 and the outer diameter of the cylindrical portion 11, is set to be smaller than the outer diameter D of the inner ring 31. Thereby, when inserting the cylindrical part 11 in the extraction pipe | tube 23, it can prevent that the protrusion 32 interferes with the internal peripheral surface 232 of the extraction | pouring cylinder. Thus, the opening tool 3 of Example 2 can have the function of the cap as a sealing member by providing the inner ring 31 and the protrusion 32.
