DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The beverage container 1 of the present invention includes a container body 2, a lid body 3, and a sheet material 4.
[0009]
The container body 2 is formed of a synthetic resin and has a bottomed cylindrical shape with an upper end opening formed by projecting a flange 6 outward from the upper end edge of the peripheral wall 5 and stores beverages therein. The shape may be cylindrical as in the embodiment shown in the drawings, or may be other cylindrical shapes.
[0010]
The lid 3 is also made of synthetic resin, and the flange 7 fixed to the upper surface of the flange 6 extends outward from the lower end edge of the peripheral wall 8, and the container body upper end opening is opened by the top wall 9 extending from the upper end edge of the peripheral wall 8. Is configured to be closed. Further, a central portion of the top wall 9 is formed in a depressed portion 9a through an annular vertical wall 10, and a lip contact portion 11 having a concave shape with a front surface and an open top surface is formed on the front outer surface of the peripheral wall 8. . The lip abutting portion 11 has a size convenient for pressing a general lip. In this embodiment, the lip abutting portion 11 is connected to the outer wall of the vertical wall and the lower edge of the vertical wall. And an inclined wall outer surface slightly inclined downward.
[0011]
Further, the lid 3 has a cutout lid surrounded by a thin broken portion 12 extending from the front portion of the top wall 9 behind the lip contact portion 11 to the depressed portion 9a through the front portion of the hanging wall 10. 13 is provided. In this embodiment, the cutout lid 13 has a triangular shape with one apex directed toward the rear center in the depressed portion 9a, and is formed in a horizontally long rectangular shape in the vertical wall 10 and the top wall 9 portion of the non-depressed portion. is doing. Further, a pull ring 14 is integrally projected from the rear end portion of the cut lid, and by pulling up the pull ring 14, the thin-walled broken portion 12 is cut, the cut lid 13 is removed, and the drinking mouth 15 is opened. It is configured as follows.
[0012]
The lid 3 can be fixed to the container 2 by fusing the flanges together by a conventional method such as ultrasonic welding.
[0013]
The sheet material 4 is fixed to the lid at the time of molding the lid 3 by a method such as in-mold molding. The sheet material 4 covers the entire upper surface of the top wall 9 of the lip abutting portion 11 and the non-depressed portion and is forced. It is fixed so that it can be peeled off. In addition, a rupture portion 16 is formed that longitudinally cuts the both side positions of the cutting lid 13 formed on the top wall 9 of the non-recessed portion from the upper end portions on both sides of the sheet material of the lip contact portion. The breaking portion 16 may have a structure that can be broken relatively easily even if it is formed in a perforated shape as shown in the drawing or formed thin.
[0014]
The sheet material 4 is fixed to the lid 3 so as to be able to be forcibly peeled off. The phrase “forced peeling is possible” here means that the film is fixed in a normal state, but can be peeled relatively easily if one is fixed and the other is peeled off. For that purpose, the lid and the sheet material in in-mold molding are formed of different materials having peelability, or a resin layer that is relatively peelable from the lid on the lower surface of the sheet material, so-called peeling. What is necessary is just to form a layer. As the material of the sheet material 4, a single sheet or laminated sheet of synthetic resin, a laminated sheet of paper and synthetic resin, or a single or laminated sheet obtained by applying a metal thin film layer to the synthetic resin can be employed.
[0015]
In using the container 1 configured as described above, first, if the pull ring 14 is grasped and pulled forward, the thin-walled rupture portion 12 is sequentially broken forward from the rear portion, and at that time, each rupture portion 16 of the sheet material 4 is broken. The portion that is broken and fixed to the cutout lid 13 is fixed as it is, the portion that is fixed to the lip contact portion 11 is peeled off, the cutout lid 13 and the separated sheet material 4a are removed, and the drinking mouth 15 And the surface of the lip contact portion 11 is exposed. The remaining sheet material 4b remains on the upper surface of the lid top wall 9.
[0016]
The embodiment shown in FIG. 4 shows another embodiment of the present invention. In this embodiment, instead of the sheet material 4, a cut formed on the lip contact portion 11 and the top wall 9 of the non-recessed portion. A sheet material 4A that covers the lid 13 and is fixed so as to be able to be forcibly separated is provided. Since other configurations are the same as those in the above embodiment, the same reference numerals are given and description thereof is omitted.
[0017]
The sheet material 4A is not limited to covering only the upper surface of the lid top wall 9 of the lip contact portion 11 and the non-depressed portion as described above, but the lip contact portion 11 and the top of the lid portion of the non-depressed portion. It is also possible to cover a wider range of the lid top wall 9 including the cut lid 13 formed on the wall 9. Further, in the case of a very wide range, it is possible to use a fracture portion as in the above embodiment.
[0018]
【The invention's effect】
As described above, in the container of the present invention, the central portion of the top wall 9 extending from the upper end edge of the peripheral wall 5 is formed in the depressed portion 9a via the annular vertical wall 10, and the front surface and the upper surface are opened to the outer surface of the front portion of the peripheral wall 5. It has a lid 3 formed with a lip abutting portion 11 having a concave shape, and extends from the front of the top wall 9 behind the lip abutting portion 11 to the depressed portion 9a via the front of the hanging wall 10 A cut-off lid 13 with a pull ring surrounded by a thin-walled rupture portion 12 is provided, and the upper surface of the top wall 9 of the lip contact portion 11 and the non-depressed portion is covered so as to be able to be forcibly separated. Since the sheet material 4 is provided with the rupture portions 16 that longitudinally cross the front and rear sides of the cutout lid 13 formed on the top wall 9 of the non-depressed portion from the upper end portions on both sides of the lip contact portion portion, before opening In this case, the lip abutting portion to which the lips are applied is covered with a sheet material, and there is no possibility that dust or the like adheres to it. When sealing, the opening of the drinking mouth and the peeling of the sheet material at the lip contact portion can be performed together by an extremely simple operation of pulling up the pull ring.
[0019]
In addition, the sheet material is fixed to the lid so that it can be forcibly separated by in-mold molding or the like. At that time, the sheet material is fixed by covering the entire upper surface of the top wall 9 of the lip contact portion and the non-depressed portion. Since the sheet material is configured as described above, the sheet material has the contour shape of the top wall of the lid body, and there is an advantage in manufacturing that the sheet material can be easily set on the mold.
[0020]
In the container according to the second aspect of the present invention, since it is not necessary to cut the sheet material at the broken portion upon opening, the opening can be performed more reliably and easily.
