Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage bag for storing clothes, bedding and other bedding, fresh food and other items.

[0002]

[Prior art]

 Conventionally, a storage bag capable of venting air has been developed in order to reduce the bulkiness of clothes and the like and reduce the storage space and improve the handleability during travel and long-term storage. The structure of such a conventional storage bag is configured by forming an opening for inserting and removing articles such as clothes in a synthetic resin bag and providing a chuck member for closing the opening. There is. This storage bag is used after the articles are stored in the bag through the opening and then the suction nozzle is inserted into the opening and the part of the chuck member excluding the nozzle insertion part is closed. Then, connect the nozzle to an air-removing device such as an electric vacuum cleaner or a manual pump, operate the device, remove the air inside the bag, and then remove the nozzle to completely seal the chuck member. In this conventional example, the tip of an external component may be directly inserted into the opening of the bag body to suck air without using the nozzle. As a result, the bag shrinks and the article is compressed into the bag, so that the bag is not bulky, and it is possible to save space and improve handleability.

[0003]

[Problems to be solved by the device]

 However, conventional storage bags require separate external parts such as an air intake nozzle and air bleeding device, which is cumbersome to handle and may require carrying these external parts during travel. , Was complicated. In addition, when using an electric vacuum cleaner as an air bleeding device, there was a problem that the motor overheated due to overload at the time of intake and failed. Furthermore, when the tip of the intake nozzle or the external part is pulled out, air easily flows back into the bag body, which limits the bulkiness.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a storage bag that does not require external parts, is easy to handle, and is free from outside air.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a storage bag of the present invention comprises a synthetic resin bag body having an opening and an opening for opening and closing articles, an openable chuck member for closing the opening of the bag body, and the bag. It is provided with a check valve for guiding the air inside the body to the outside and performing an opening / closing operation for preventing the outside air from entering the bag body.

[0006]

[Action]

 In the above structure, the air inside the bag is released from the check valve to the outside by pressing the bag with the chuck member closed. As a result, the air inside the bag is removed. Since the check valve prevents the outside air from entering the bag body during and after the air bleeding, the air bleeding state can be reliably maintained.

【Example】

First Embodiment FIG. 1 shows a first embodiment of the present invention, in which a storage bag 1 includes a bag body 2 and a check valve 3 provided on the bag body 2. The bag body 2 is formed by stacking gas barrier packaging materials on top of each other and sealing or adhering the peripheral portion thereof, and an openable / closable opening 4 is formed in the peripheral portion on one side. As the material of the bag body 2, a synthetic resin such as polyethylene or a suitable plastic sheet laminated with aluminum foil is used.

A chuck member 10 for closing the opening 4 is attached to the opening 4 portion of the bag 2. The chuck member 10 is provided over the entire length of the opening portion 4, and the bag body 2 is hermetically closed by closing the chuck member 10. In the bag body 2, stored articles 6 such as clothes, futon, and food items are put in and taken out through the opening 4. By properly storing oxygen absorbers and insect repellents in the bag body 2 depending on the items to be stored, it is possible to prevent oxidation and insect worming of the items.

The check valve 3 is arranged on the side of the bag 2 opposite to the opening 4. As will be described later, the check valve 3 guides the air in the bag body 2 to the outside and prevents the outside air from entering the bag body.

FIG. 2 shows an example of the chuck member 10, which has a male chuck 11 and a female chuck 12 which are attached to the facing packaging material of the bag body 2 by adhesion or the like, or are continuously or integrally molded. There is. The male chuck 11 is formed in an arc shape, while the female chuck 12 is formed with an arc-shaped recess 13 into which the male chuck 11 is fitted. The male chuck 11 and the female chuck 12 are made of the same kind of plastic, and when the male chuck 11 and the female chuck 12 are fitted to each other, they are brought into close contact with each other to prevent them from coming off. As a result, the opening 4 of the bag body 2 can be reliably sealed.

3 and 4 show the structure of an example of the check valve 3. The check valve 3 is inserted into the bag body 2 from the side opposite to the opening 4, and the periphery is fixed to the bag body 2 by being bonded or welded. The check valve 3 is configured by providing a flexible valve body 32 in an air passage 31 whose both ends are open. The valve body 32 is formed in a size that blocks the flow passage 31, and a stopper projection 33 that abuts an end surface of the valve body 32 on the bag body 2 side is formed inside the flow passage 31. As a result, the valve body 32 is prevented from collapsing in the direction of the bag body 2 and closes the flow path 31, while it can collapse in the opposite direction of the bag body 2 and the flow path 31 is opened, and the bag body body is opened. Internal air flows out.

In the above structure, the opening 4 is closed by inserting the predetermined article 6 into the bag 2 through the opening 4 and closing the chuck member 10. In this state, the bag body 2 is pressed, and in the case of small clothes or the like, the bag body containing these is wound to apply pressure to the inside air. As a result, the valve body 32 falls down as shown in FIG. 4, the check valve 3 is opened, and the air in the bag body 2 is discharged from the flow path 31. Due to the release of air, the inside of the bag body 2 is in a reduced pressure state, the article 6 is compressed in the bag body 2, and the bulkiness thereof is reduced. After the pressure applied to the bag body 2 is released, the valve body 32 closes the flow path 31 as shown in FIG. To prevent. Therefore, since the depressurized state of the bag body 2 is maintained, the article is kept in the compressed state and the bulkiness is not restored.

In this embodiment as described above, an external component for venting air is not required, and thus the handling is simple. Also, it is not necessary to carry external parts. In addition, since the invasion of the outside air into the bag body 2 is prevented during and after the air bleeding, the depressurized state of the air bleeding can be reliably maintained.
