Description

[Detailed description of the invention] Industrial application field This invention is widely used for commercial and household purposes, and is suitable for temporarily covering the mouths of containers such as bottles, cans, and containers. Regarding the simple lid.

Conventional technology and its problems Conventionally, coiled aluminum foil has been used for the above-mentioned applications. When using it, unwind the coiled aluminum foil, cut it slightly larger than the size of the container mouth, cover the container mouth with the cut aluminum foil, and insert the aluminum foil from the container mouth. The protruding peripheral edge of the aluminum foil was folded from the mouth of the container to the lower part, but the aluminum foil that was placed over the container in this way formed a cap shape and was simply placed on the container. Since the aluminum foil is only attached to the container, it is easy to remove the aluminum foil from the container. There was a problem that it was troublesome because it was made to fit in close contact with each other.

The purpose of this invention is to provide a simple lid that solves the above-mentioned problems.

Means for Solving the Problems The simple lid according to this invention includes an aluminum foil consisting of a container opening covering part and an extension part provided around the periphery of the aluminum foil, and at least multiple positions of the extension part of the entire lower surface of the aluminum foil. It includes an adhesive layer formed in a scattered manner and a release paper covering the adhesive layer.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings.

The simple lid, as shown in FIG.
Adhesive layer 15 formed on a part of the lower surface
and a release paper 16 for protecting the adhesive layer 15. In FIG. 1, the release paper 16 is shown to have already been peeled off from the adhesive layer 15. The aluminum foil 14 has a thickness of 9 to 50 .mu. and is made of material A1N30H-O and is punched out into a circular shape from a strip.In addition to the one shown in the figure, there are prepared aluminum foils of different sizes with different outer diameters. As an example, the size is φ80,
They are φ100, φ120, φ140, φ160, etc. The aluminum foil 14 can be divided into two parts, one of which is the container opening covering part 17, and the other part is an extension part 18 provided around the periphery of the container opening covering part 17. (The boundaries of the parts are shown in dashed lines in Figures 2 to 4). The container opening covering part 17 is attached to the container opening 12.
It has a circular shape that is just large enough to cover the area. The extension part 18 has an annular shape large enough to cover the upper end of the body 13. The adhesive layer 15 is formed by part-coating an adhesive on the lower surface of the aluminum foil sheet 14, and an example of the type of adhesive is an acrylic emulsion type adhesive. There are various possible adhesive coating patterns, examples of which are shown in Part 2.
It is shown in FIG. 4 from the figure. In the case shown in FIG. 2, the extension part 18 is formed into two continuous lines that extend parallel to each other across the container mouth covering part 17, and the width of the lines is 3 to 3.
It is 4mm. In the case of FIG. 3, the line shape of FIG. 2 is discontinuous. The one in Figure 3 is the extension part 1.
Each of the positions where the outer edge of No. 8 is divided into four equal parts in the circumferential direction has a substantially rectangular dot shape. Furthermore, it is of course possible to form the adhesive layer 15 on the entire lower surface of the aluminum foil 14, but it is not necessary. Although not shown in detail, the release paper 16 is a piece of thin paper coated with a release agent such as silicone on one or both sides, and is formed to have the same shape and size as the aluminum foil 14, and is similar to the size of the aluminum foil 14. Multiple types are available for this purpose.

When using the lid, pull the aluminum foil 14 and release paper 16 apart from each other, peel off the release paper 16 from the adhesive layer 15, cover the container mouth covering part 17 of the aluminum foil 14 over the container mouth 12, and then remove the release paper 16 from the adhesive layer 15. The extension portion 18 may be pressed against the upper end of the container body 13. Then, since the adhesive layer 15 adheres to the upper end of the container body 13, the aluminum foil 14 cannot be accidentally removed from the container 11. It goes without saying that the aluminum foil 14 can be easily removed from the container 11 by peeling off the adhesive layer 15.

Effects of the invention According to this invention, when the release paper is peeled off from the adhesive layer, the container opening covering part of the aluminum foil is placed over the container opening, and the extended part is pressed against the container.
The adhesive layer adheres to the container, making it impossible to remove the aluminum foil from the container.
There is no need to use a rubber band or rub aluminum foil unnecessarily, and the container opening can be easily covered.
