Abstract

(57) [Abstract] [Problem] To enhance the safety of a stopper when a container is opened. SOLUTION: A resin material surface such as a laminated film protrudes from a hard material surface of a stopper by 0.3 to 5.0 mm so that the stopper can be safely opened and reopened regardless of bending or ironing of the stopper. I made it possible.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a stopper for sealing an opening of a bag-shaped container made of a flexible material such as a plastic film or paper.

[0002]

[Prior art]

 It is common practice to manufacture, sell and store product materials in flexible bag-shaped containers (hereinafter referred to as “containers”) made of plastic film, paper or their multilayer materials. . For example, food materials such as snacks are put in for sale.

[0003] In this case, in order to prevent the contents from solidifying by absorbing moisture in the outside air after the contents are once opened, or to prevent the odor of the contents from leaking out and diverging, a so-called zipper is provided at the container opening. There is a case where a seal member called “a seal member” is provided. Zippers are excellent in keeping the air tightness, but depending on the material of the container, they are not only unsuitable for installation, but also have the disadvantage of high cost.

Up to now, as shown in FIG. 1, a stopper 1 made of a hard material is attached to the opening of the container B by applying an adhesive to one side, and the stopper is bent in the direction of the arrow to open the container. In some cases, the contents are sealed to prevent the contents from absorbing moisture in the outside air and solidifying even after the contents are once opened, and to prevent the odor of the contents from escaping to the outside.

As shown in FIG. 2, such a stopper is entirely made of a hard material 3. For example, a single-layer or multilayer film 2 is laminated on a metal such as aluminum. With this type of stopper, when the container is opened and stored until reopening, the container opening is bent, and then the stopper is pressed down with a finger to fix the bent portion of the bending opening to secure the container. Sealing has been performed.

[0006]

[Problems to be solved by the invention]

 However, in the conventional stopper, a hard material 3 such as an aluminum metal and a laminated material of a film are integrally cut and cut by punching. However, the hard material 3 tends to protrude from the periphery of the stopper due to contraction or turning over. When closing the container using these stoppers, in order to enhance the sealing effect, bend the opening of the container and then press or stop the stopper of length L made of hard material with a finger. It was necessary to squeeze the utensils. At that time, there is a possibility that the wrapping material of the container may be damaged at the edge of the protruding hard material 3 or that a human hand or finger may be cut or cut off at the cross section of the stopper.

[0007]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problem, and the present invention is directed to a bag-like container made of a flexible material such as a plastic film, paper, or a multilayer material thereof, which is provided at an opening portion thereof. A fastener to be attached, which has a longer side longer than the longer side of the opening and has a resin material surface protruding outward from a hard material flat portion in a peripheral portion of the stopper. About.

According to a second aspect of the present invention, the width of the resin material surface protruding from the hard material plane portion is 0. It features a stop that is 3-5.0 mm.

[0009] Further, a third aspect of the present invention relates to a stopper characterized in that the resin material surface is laminated with a hard material. As the resin material to be laminated, expanded polypropylene (hereinafter referred to as “OPP”) or the like can be used.

The stopper according to the present invention can be used by being attached to a bag-like container with an adhesive or the like. The bag-shaped container can be used for any kind of contents, but it is suitable for materials that have hygroscopicity, materials that easily deteriorate due to contact with air, or materials that emit an odor. For example, it is not limited to seasonings such as sugar and salt, palatable foods such as regular coffee and instant coffee, foodstuffs such as confectionery and seaweed, etc. Can be adapted.

When the stopper according to the present invention is used, as shown in FIG. 4, even after the amount of the contents is reduced, the stopper is attached to the opening of the container in the direction of the arrow as shown in FIG. By folding, it is possible to securely and securely seal the container opening portion according to the amount of the contents, and it is possible to keep contact between the contents and the air to a minimum.

[0012]

[Embodiment of the invention]

 Next, an embodiment of the stopper 1 'of the present invention is shown in FIG. When laminating a resin material 2 'layer on a hard material 3' having a width W made of aluminum metal foil, a stopper provided with a resin material surface 2 'protruding outward from the front of the hard material 3' is required. It is shown.

As shown in FIG. 3B, the hard material 3 ′ is made of an aluminum metal foil having a thickness of 150 μm and a width of 10 mm. It is provided by laminating OPP resin with a thickness of 40 μm so as to protrude 0 mm. On one surface of the aluminum metal foil 3 ', an adhesive 5 is applied to be attached to the opening of the bag-shaped container, and four surfaces are printed as appropriate.

[0014]

[Effect of the invention]

 By using the stopper according to the present invention, when the opening of the bag-shaped container is sealed, the stopper prevents the container from being damaged and ensures that the opening is securely sealed. There was no danger of fingers or the like being damaged by bending or ironing of the stopper, and safety was improved.
