Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems that an opening is not readily detached and a content is scattered due to a shock of detachment and sometimes contaminates hands since the opening is detached by holing a pull tab by a finger in a conventional opening structure. <P>SOLUTION: A tab having a projection is rotatably provided, and an opening formed with an outline having a thin thickness is provided on the top plate of a container. The pull tab is raised and rotated. The projection provided on the pull tab is made to abut and pressed against the opening, thereby breaking the thin groove forming the opening. In this process, the scattering of the content is prevented by the pull tab itself. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

発明の詳細な説明Detailed Description of the Invention

本発明は、容器の開栓構造に関するものである。  The present invention relates to a container opening structure.

従来の容器は容器天板に周囲を弱くした開口部を作り、そして、容器天板上に指をかけるプルタブを設けている。（例えば、特許文献１参照。）  In the conventional container, an opening having a weakened periphery is formed in the container top plate, and a pull tab for placing a finger on the container top plate is provided. (For example, refer to Patent Document 1.)

特開２００５−１５３９９２号 公報  JP-A-2005-153992

従来のプルタブをもつ容器の開栓構造においては、プルタブが小さく指がかけにくく、プルタブを引っ張り開口部を開ける際に、内容物が飛散して手を汚すことがある。  In a conventional container opening structure having a pull tab, the pull tab is small and difficult to put on with a finger, and when the pull tab is pulled to open the opening, the contents may scatter and dirty hands.

本発明は、従来の構造が持つ問題を解決しようとするものであり、開口部を容易に開けて、内容物の飛散を防止することを目的とするものである。  An object of the present invention is to solve the problems of the conventional structure, and it is an object of the present invention to easily open an opening and prevent scattering of contents.

上記の課題を解決するため、本発明ではプルタブと肉厚を薄くした輪郭で形成した開口部を容器天板に設け、そして、突起をプルタブ、または、開口部に設けたものである。  In order to solve the above problems, in the present invention, an opening formed with a pull tab and a thin outline is provided in the container top plate, and a protrusion is provided in the pull tab or the opening.

また、第２の解決手段は突起を持つプルタブと、肉厚を薄くして形成した開口部を容器天板に設け、更に、開口部内部に小開口部を設けたものである。  The second solution means is to provide a pull tab having a protrusion and an opening formed with a reduced thickness on the container top plate, and further provide a small opening inside the opening.

上記第１の課題解決手段による作用は次のとうりである。すなわち、プルタブを引き起こし回転させ、プルタブに設けた突起を開口部に当てて押し付けることにより開口部を形成する薄い溝を破る。この際、内容物の飛散はプルタブ自体がくいとめる。  The operation of the first problem solving means is as follows. That is, a pull tab is raised and rotated, and a thin groove forming the opening is broken by pressing a protrusion provided on the pull tab against the opening. At this time, the pull tab itself can prevent the contents from being scattered.

上記第２の課題解決手段による作用は、上記第１の課題解決手段と同様にプルタブを引き起こし回転させ、プルタブに設けた突起を小開口部に当てて押し付けることにより小開口部を突き破り、容器内部のガスを抜き、更に力を加え、開口部を破る。この際、内容物の飛散はプルタブがくいとめる。The action of the second problem solving means is the same as that of the first problem solving means. The pull tab is caused to rotate, the protrusion provided on the pull tab is pressed against the small opening, and the small opening is broken through. Remove the gas and apply more force to break the opening. At this time, the pull tab is not enough to scatter the contents.

上述したように本発明の開栓構造は、開口部を容易に開け、また、内容物の飛散を防止することができる。  As described above, the opening structure of the present invention can easily open the opening and prevent the contents from scattering.

第１の実施形態の容器天板の斜視図である。It is a perspective view of the container top plate of 1st Embodiment. 図１の容器天板の断面図である。It is sectional drawing of the container top plate of FIG. 第２の実施形態の容器天板の斜視図である。It is a perspective view of the container top plate of 2nd Embodiment.

以下、本発明を発明の実施形態に基づいて詳細に説明する  Hereinafter, the present invention will be described in detail based on embodiments of the invention.

実施例について図面を参照して説明すると、図１のように突起３を設けたプルタブ２を容器天板４のリベット５に回動自由に取り付け、そして、容器天板４の肉厚を薄くして形成した開口部１作る。図２のようにプルタブ２を引き起こし回動させ、プルタブ２に設けた突起３を開口部１に当てて押し付けることにより開口部１を形成する薄い溝７を破る。この際、内容物の飛散はプルタブ２自体がくいとめる。  The embodiment will be described with reference to the drawings. As shown in FIG. 1, the pull tab 2 provided with the protrusions 3 is freely attached to the rivet 5 of the container top plate 4 and the thickness of the container top plate 4 is reduced. Make the opening 1 formed. As shown in FIG. 2, the pull tab 2 is raised and rotated, and the projection 3 provided on the pull tab 2 is pressed against the opening 1 and pressed to break the thin groove 7 forming the opening 1. At this time, the pull tab 2 itself can be prevented from scattering the contents.

他の実施例としては図３のように、突起３を設けたプルタブ２を容器天板４のリベット５に回動自由に取り付け、そして、容器天板４の肉厚を薄くして形成した開口部１と、更に、開口部１の内部に小開口部６を設ける。プルタブ２を引き起こし回動させ、プルタブ２に設けた突起３を小開口部６に当てて押し付けることにより、突起３が小開口部６を突き破り、容器内部のガスを抜き、更に力を加え、開口部１を開ける。この際、内容物の飛散はプルタブ２がくいとめる。本実施例では小開口部６は開口部１の内部に設けているが、小開口部６と開口部１を近接して設けてもよい。  As another embodiment, as shown in FIG. 3, the pull tab 2 provided with the protrusion 3 is freely attached to the rivet 5 of the container top plate 4 and the opening formed by reducing the wall thickness of the container top plate 4 A small opening 6 is provided inside the opening 1 and the opening 1. The pull tab 2 is raised and rotated, and the protrusion 3 provided on the pull tab 2 is pressed against the small opening 6 to press the protrusion 3 so that the small opening 6 is breached, the gas inside the container is extracted, and further force is applied. Open part 1. At this time, the pull tab 2 is sufficient for scattering the contents. In this embodiment, the small opening 6 is provided inside the opening 1, but the small opening 6 and the opening 1 may be provided close to each other.
