JPS5847015Y2 - Moisture-proof, easy-to-open container - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a container that is moisture-proof and easy to open.

Conventionally, most containers that have a lid bonded to a container body are used by simply peeling off part or all of the adhesive between the container body and the lid.

Therefore, increasing the adhesive strength between the container body and the lid will make it difficult to open the seal, and if you try to forcefully open the seal, a large amount of force will be applied, which may deform the opening of the container body or the container itself. If the adhesive strength between the container body and the lid is reduced in order to make it easier to use, there are drawbacks such as leakage of contents and deterioration of barrier properties.

The present invention aims to provide a container that can be opened with one touch by improving the lid in consideration of the above points, and furthermore, the container body and lid material are moisture-proof so that they can also be moisture-proof. It is made using a sheet having a

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

As shown in FIGS. 1 and 2, the container body 1 is formed of a sheet in which a base layer 5 of paper or the like, an aluminum foil layer 6, and a thermoplastic resin layer 7 of Botethylene or the like are laminated in this order from the outside.

The lid 2 is made up of two lid materials 3 and 4, and both lid materials 3,
Both strings 4 are semicircular in shape, and knobs 8 and 9 each having an appropriate width are provided at the center of the string.

The opening of the container is completely sealed by both the lids 3 and 4. For example, the chord part of the lid 3 is folded back to an appropriate length, and the string part of the lid 4 is folded back to the folded chord part of the lid 3. Overlap.

That is, the inner surfaces of both lid materials 3 and 4 are joined at the chord part, and both lid materials are bonded only at the base of this overlapping portion, that is, near the folding line of the lid material 3, to form a circular lid 2.
shall be.

Naturally, the knobs 8 and 9 provided on the string parts of the lid members 3 and 4 also overlap.

Here, the lid members 3 and 4 are laminated in this order from the outside: an aluminum foil layer 10, and a thermoplastic resin layer 11 that has been stretched in the direction perpendicular to the strings, in other words, in the direction in which the knob is provided. The container of the present invention is constructed by heat-sealing the lid 2 to the container body 1 at the top curl portion 12.

The aluminum foil layers of the container body 1 and the lids 3 and 4 are provided to maintain moisture resistance, and any moisture-proof material may be used in place of the aluminum foil.

In addition, in order to bond the container body 1 and lid 2 by heat sealing, it is necessary to provide a thermoplastic resin layer on the innermost surfaces of the container body 1 and lid 2, but regardless of heat sealing, a suitable adhesive If the container body 1 and the lid 2 are bonded together using a thermoplastic resin layer, it is not necessarily necessary to form a thermoplastic resin layer on the innermost surface.

It is extremely easy to open a container with the above structure.
Both lids 3 are removed by pulling up the knobs 8 and 9.
, 4 simultaneously have a cut the width of the knobs 8 and 9, and as the lifting operation continues, since the lid material has a resin layer that has been uniaxially stretched, it is easily torn straight from the cut, and the knob is removed. An opening 13 having the same width as 8 and 9 is formed.

This state is shown in FIG. In this way, two pieces of lid material 3
, 4 are integrated at the overlapping part to form the lid 2,
The protruding knobs 8 and 9 for making the opening 13 can be provided, so the opening 13 can be easily made by the above-described operation, and since the opening 13 has a striped shape, it is easy to remove the contents. Advantageous for pouring.

Furthermore, by changing the widths of the knobs 8 and 9, it is possible to obtain an opening with a desired width.

In addition, when pulling up the knobs 8 and 9, the adhesive strength between the lid 2 and the container body 1 is set to the breaking strength of the lid material so that the entire lid 2 does not peel off from the container body 1 before following the above-mentioned opening process. It is necessary to set it considerably larger than that.

The container according to the present invention is as described above, and an opening having the same width as the knob can be easily obtained by simply pulling up the knob, and when sealed, the container body and lid are covered with aluminum foil, etc. Since it has a moisture-proof layer, it also has an excellent moisture-proofing effect.
