Description

[Detailed description of the invention] [Industrial field of application] This invention is designed to store clothing, bedding, and other items through the storage opening, and then weld the storage opening to completely seal it. This invention relates to a storage bag suitable for long-term storage.

[Prior Art] This type of storage bag is described in Japanese Utility Model Application Publication No. 116583/1983.

That is, this storage bag is made by laminating a polyethylene film used as a hot melt onto an oxygen-impermeable stretched polyethylene terephthalate film coated with polyvinylidene chloride, and then An attachable fastener made of a low melting point thermoplastic resin such as a copolymer of ethylene and vinyl acetate or an anonomer resin is provided on the inner surface of the article storage opening formed at one end, and is used to seal the article storage opening. In this method, a fastener is attached, and the fastener is welded by applying heat and pressure from the outer peripheral surface of the package using a household iron, thereby sealing the article storage opening.

[Problems to be solved by the invention] In the case of the above-mentioned conventional storage bag, when heating and pressurizing the outer peripheral surface of the package with a household iron, the fastener is welded due to the low melting point of the oxygen-impermeable film. During this process, the oxygen-impermeable film may melt and adhere to the heating surface of the iron, or the oxygen-impermeable function may be impaired. especially,
Since the welding of the article storage opening is done by a housewife using a household iron, the iron temperature, heating time, pressure force, etc. are not strictly controlled, and in the case of this storage bag, Since the height of the fasteners to be thermally welded is high, it takes time to thermally weld the fasteners, and together with this, more heating and pressure is required than necessary, which frequently causes the above-mentioned problem.

In addition, in the case of the above-mentioned conventional storage bag, it is necessary to provide a fastener that can be attached to the inner surface of the article storage opening of the package, which is very troublesome to manufacture.
This will result in a significant increase in costs.

The present invention was developed in view of these circumstances, and it not only allows the storage bag's storage opening to be easily and reliably sealed using a household iron, but also allows for household ironing. Even if housewives or others apply more heat and pressure than necessary, the oxygen-impermeable material (non-breathable material) will not adhere to the heating surface of the iron or impair the oxygen-impermeable (non-breathable) function, and it will last for a long time. The purpose of the present invention is to provide an inexpensive storage bag for clothing, etc., which can reliably seal items.

[Means for Solving the Problems] In order to achieve the above object, the storage bag for clothing, etc. of the present invention is a packaging body having an article storage opening in which a non-breathable layer is formed on the inner peripheral surface of the heat-resistant layer. and, formed at least on the inner circumferential surface of the non-breathable layer facing the article storage opening of this package, and having a temperature lower than the melting point of the heat-resistant layer and the non-breathable layer, from the outer circumferential surface side of the heat-resistant layer of the package, It is equipped with a hot melt layer that can be melted by heating and pressurizing with an iron to seal the article storage opening of the package.

[Function] According to the storage bag having such a structure, by heating and pressurizing the article storage opening from the outer peripheral surface of the heat-resistant layer of the package using a household iron, the hot melt on the opposing inner peripheral surface of the article storage opening is heated and pressurized using a household iron. Since the layer has a lower melting point than the heat-resistant layer and the non-breathable layer and is just a layer, only the hot melt layer melts and integrates easily in a short time, making it possible to easily seal the storage opening of the storage bag at home. can.

Moreover, by providing a heat-resistant layer on the outer layer,
Even when a high-temperature iron is brought close to the outer circumferential surface of the article storage opening, wrinkles are less likely to form on the outer circumferential surface of the article storage opening, and together with the fact that the hot melt layer is easily melted and integrated, the articles in the storage bag are The storage opening can be reliably sealed.

In addition, by providing a heat-resistant layer on the outer layer side of the non-breathable layer, even if a housewife or the like applies more heat and pressure than necessary, the material of the non-breathable layer will not stick to the heating surface of the iron. In addition, the heat-resistant layer reduces the effect of heating on the non-air permeable layer, and effectively prevents the function of the non-air permeable layer from being impaired.

In addition, in the case of the storage bag of the present invention, the article storage opening can be reliably sealed with a simple hot melt layer formed on the inner peripheral surface of the non-breathable layer as described above. There is no need to provide an attachable fastener made of thermoplastic resin on the inner surface, and compared to the case where such a fastener is provided, manufacturing is not complicated and the storage bag can be made at a low cost.

[Example] Hereinafter, an example of the storage bag for clothing, etc. according to the present invention will be shown.

FIGS. 1 and 2 are partially cutaway front views of a storage bag in which a hanger for suspending clothing is assembled, before and after the clothing is stored, respectively. In these figures, the storage bag 20 includes a packaging body 20A having an article storage opening 21 formed at its lower end for loading and unloading clothing A, and an integrally formed entire inner peripheral surface of the packaging body 20A including the article storage opening 21.
It includes a sheet showing adhesive properties that can be heated and melted with a household iron, that is, a hot melt layer 20B.

This packaging body 20A is made by coating or laminating a synthetic resin sheet _{20A 2 with} high air impermeability on the inner peripheral surface side of a synthetic resin sheet 20A 1 with high heat resistance, and stores articles in the packaging body 20A. Mouth 2
A hot melt layer 20B is coated on the inner circumferential surface of the sheet 1, that is, the inner circumferential surface of the highly air-impermeable synthetic resin sheet _20A2 .

As the synthetic resin sheet 20A ₁ with high heat resistance, a polyamide resin sheet (6,6 nylon, 6 nylon) is recommended, and as the synthetic resin sheet 20A ₂ with high air impermeability, a vinylidene chloride sheet is recommended. Polyethylene is recommended as the material for forming the hot melt layer 20B.

Reference numeral 11 denotes a hanger, which is made of, for example, a hard synthetic resin material into a hollow shape by blow molding or vacuum homing, and has a garment suspension part 12 of a known shape for suspending the garment A;
An opening is formed at a suitable position in the suspension support part 13 which becomes the outside of the storage bag 20 in a suspended state, which will be described later, and an on-off valve is installed in this opening as shown in FIG. (Check valve) 15 is installed. This on-off valve 15 has a valve body 1 inside the suction port 14.
