Abstract

PURPOSE:To prevent a shape collapsing of a bag from generating when the bag is displayed at a store, etc., by a method wherein a bag body without air permeability is put in a bag such as a purse, etc., and a fluid is injected in the bag body, and the bag body is expanded. CONSTITUTION:A bag body 2 which is put in a bag 1 in order to retain the shape of the bag 1 is formed of a flexible synthetic resin sheet or rubber sheet without air permeability, and is expanded by injecting an appropriate quantity of a fluid in the bag body 2 after the bag body 2 is put in the bag 1. Then, a deformation of the bag 1 is prevented from generating by the bag body 2 by bringing the outer peripheral surface of the expanded bag body 2 into contact with the inner peripheral surface of the bag 1, and the shape of the bag 1 is retained so that the appearance may not be spoiled. When the bag body 2 is expanded, an air pump is used, and after air is forced into the bag body 2 from a hose 3, the end of the hose 3 is closed by a plug 4, etc. Or, a fluid is filled in the bag body 2 by piercing an injection needle in a rubber plug which is attached on the end of the hose 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shape retention device for bags such as handbags.

[0002]

2. Description of the Related Art Conventionally, a handbag displayed at a store or the like is filled with a stuffing so that it does not look bad due to its shape.

As the above-mentioned padding, for example, rolled paper, a soft synthetic resin sheet in which air is scattered in a scattered manner, or a lump having elasticity such as urethane resin is used.

[0004]

When the above-mentioned method is adopted, in the case of the soft synthetic resin sheet for paper, the rounding work is extremely troublesome and it is difficult to form the bag to match the shape of the bag.

Further, in the case of an elastic lump, it is difficult to cut a shape corresponding to the shape of the bag, and a plurality of large and small lumps are sequentially packed to retain the shape, so that the packing work is troublesome. At the same time, it takes time to select the lumps having different sizes. In particular, in the case of a soft synthetic resin sheet or a lump having elasticity, since it is bulky, it needs to be stored in a wide space and the cost is significantly increased.

[0006] Therefore, an object of the present invention is to fill a bag which is not breathable with air, gas or liquid and to keep the shape of the bag by the expanding bag.

[0007]

In order to solve the above problems, the present invention is a bag such as a handbag, in which a bag having no air permeability is housed in the bag, and a fluid is put into the bag. The method of injecting and expanding the bag body is adopted.

[0008]

[Function] When the above method is adopted, after the bag body is stored in a bag such as a handbag to be displayed,
Inject a fluid such as air, gas, or liquid into the bag,
Inflate the bag.

Then, the outer peripheral surface of the expanded bag contacts the inner peripheral surface of the bag, and deformation of the bag is prevented by the bag, that is, the expanded bag retains the shape of the bag.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, 1 is a bag. The bag 1 is not limited to the illustrated handbag and may be other bags.

Reference numeral 2 denotes a bag body which is housed in the bag 1 and has no air permeability. The bag 2 is formed using a soft synthetic resin sheet having no air permeability or a rubber sheet.

An appropriate amount of fluid is injected into the bag body 2 contained in the bag 1 to inflate the bag body 2.

Then, the outer peripheral surface of the expanded bag body 2 comes into contact with the inner peripheral surface of the bag 1, and the bag body 2 is prevented from being deformed, so that the appearance of the bag 1 is maintained.

The fluids to be injected include harmless gases and liquids other than air, and a discharge port cylinder of a manual air pump,
As shown in FIG. 3, after connecting the hose 3 communicating with the bag body 2 and pressurizing air into the bag body 2 from the hose 3 by the action of the air pump, the end of the hose 3 removed from the discharge port cylinder of the air pump is connected. It can be closed with a stopper 4, etc.
As shown in, the needle 6 of the injector is pierced into the rubber stopper 5 which is airtightly attached to the end of the hose 3 with an adhesive or the like, and the hose 3 is drawn from the needle 6 of the injector to the bag body. A liquid such as air, gas or water is injected into 2, and the needle 6 is removed after the injection.

Then, the needle can be pierced again to extract the gas or liquid for recovery, and the bag 2 can be reused.

Of course, in the case of air or gas, at the time of packaging for sale, the bag body 2 is broken by a blade or the like to release air or gas, and then the empty bag body 2 is taken out from the bag 1.

The end closure of the hose 3 is not limited to the stoppers 4 and 5 shown in the figure, and the end of the hose may be bent and stopped with a rubber band or the like in addition to the direct stoppers 4 and 5 of the bag body 2.
In some cases, a check valve with a valve that opens when fluid is pressed in is used.

In addition to the above, the fluid press-fitting means is, for example, as shown in FIG. 5, connected to the hose 3 with the gas cylinder 7 and operating the valve opening operation part 8 to supply the gas from the cylinder 7 to the hose 3.
Alternatively, the bag 2 may be press-fitted.

Furthermore, the number of bags 2 stored in the bag 1 is not limited to one.

[0021]

[Effect] Since the shape retaining device for bags according to the present invention is configured as described above, it is possible to retain the shape of the bag extremely easily and easily.

Further, even if the space inside the bag has any shape, the bag body can be inflated in that shape to retain the shape. Therefore, no void is generated between the bag and the bag body, and reliable shape retention can be guaranteed.

Furthermore, the bag body is not bulky and can be stored easily before use.
