Abstract

(57) [Summary] [Purpose] To provide a cushion bag which is not bulky when not in use, has a sufficient cushioning effect when in use, and is easy to handle. [Structure] The cushion bag according to the present invention includes a bag body 1 having a double-wall structure and an inside of the double wall.
The expansion body 31 obtained by compressing and exhausting the open-cell material and then hermetically sealing it, and the mouth portion 6 of the bag body 1 are provided. A certain string 21 is provided. When the airtight sealing of the expander 31 is broken and the open-cell material is exposed to the atmosphere, the expander 31 expands and functions as a cushion. An object can be put inside the bag body 1, and this object is protected by a cushion. The inflated bag 1 may be used as a cushion for watching sports.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag such as a handbag having a cushion, that is, a cushion bag. In particular, the present invention relates to a cushion bag in which the inflatable material that serves as a cushion is in a compressed and compact state before use and can be inflated by a simple operation during use.

[0002]

[Prior art]

 In the conventional cushion bag, as the cushion, a bubble sheet (having two air bubbles in two plastic films), a sponge or the like is used as it is. Therefore, it is bulky and difficult to store and carry even when it is not in use (before use). Also, in some cases, it took time and effort to put a cushion material such as an air mat or Styrofoam into the bag.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a cushion bag which is not bulky when not in use, has a sufficient cushioning effect when in use, and is easy to handle.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the cushion bag of the present invention includes a bag having a double wall structure and the inside of the double wall, which is obtained by compressing and exhausting the open-cell material and then hermetically sealing it. The inflatable body and the mouth portion of the bag body are provided with a mouth-squeezing means capable of squeezing the body portion and a handbag portion for holding the bag body; the airtight seal of the inflatable body is broken. When the open-cell material is exposed to the atmosphere, the inflatable body expands and functions as a cushion.

[0005]

[Action]

 When the airtight seal (for example, a film sheet) of the expander is punctured to break it, the open-cell material of the expander is exposed to the atmosphere. Then, the open-cell material that has been compressed by atmospheric pressure will return to its original state due to its own elasticity, that is, the air will enter the open-cells and the whole will expand. In this way the inflatable body acts as a cushion. Items can be placed inside the bag. This object is protected by a cushion. The inflated bag may be used as a cushion for watching sports.

【Example】

 Hereinafter, description will be given with reference to the drawings. FIG. 1 is a view showing a cushion bag according to an embodiment of the present invention. (A) is a sectional view and (B) is a partially cutaway front view. The bag body 1 has a double structure of an outer wall 3 and an inner wall 5 inside thereof. The double structure is heat-sealed in each part. A mouth part 6 is provided on the upper part of the bag body 1 so that an object can be put into the bag body from here.

The upper heat seal portion 7 is provided immediately below the mouth portion 6. The purpose of this heat sealing is to partition the string passing part 19 through which the string 21 passes and the expandable body housing part 17. The lower heat-sealing portion 9 is sealed on the lower side of the bag body 1 in a total of four sheets including two outer walls and two inner walls. The lower heat seal portion 9 defines the inner cavity 2 of the bag body and the lower end of the inflatable body storage portion 17. The side heat seal part 11 seals the side of the bag.

A closed expander housing 17 is formed between the outer wall 3 and the inner wall 5. The plate-shaped expander 31 is housed in this portion. The inflatable body 31 is an elastic open-cell material such as foamed polyurethane surrounded by a vinyl bag or the like. However, the air inside the plastic bag is exhausted with the open-cell material compressed. In this state, the expandable body 31 is hermetically sealed by means such as heat sealing. Since the outer surface of the expander 31 is under atmospheric pressure but the inside is depressurized, the open-cell material in the expander 31 is kept compressed.

A string 21 is wound around the mouth portion 6 of the bag body 1 as a mouth narrowing means. The string passing part 19 through which the string 21 is passed is defined by the inner edge of the sheet forming the outer wall and the inner wall of the bag body folded in half and the upper heat seal part 7, and has a tubular shape. ing. Windows 20 are opened in some places in the string passing portion 19, and a string 21 is exposed from the window 20. From this window you can pinch the strings and pull them together. The string 21 also serves as the "handbag" referred to in the present specification. As the handbag, the outer and inner walls of the bag may be extended upward to form a hole.

A method of using the cushion bag of the present invention will be described. After putting an object in the inner cavity 2 of the bag body 1, a hole is made in the airtight seal of the inflatable body 31 from above the outer wall 3 with the tip of a pencil or a ballpoint pen. Then, as described in the section of the above-mentioned action, the inflatable body 31 inflates and functions as a cushion. The time required for expansion is about 1 minute, and the expansion rate can be 3 to 10 times (an example). After that, pull the string 21 to squeeze the mouth portion 6 and hold the string in your hand. In addition, after inflating the inflatable body, an object may be put in the bag.

Examples of the material of the open-cell material include natural sponge, sponge rubber, expanded polyurethane, polyester, polyethylene, and cellulose foam.

[0012]

[Effect of device]

 As is clear from the above description, the cushion bag of the present invention exhibits the following effects. Since the inflatable body, which is a cushion member, is compressed before use, it is not bulky and is easy to store and carry. It is easy to use because the inflatable body can be inflated with a very simple operation. It is also possible to prevent the cushion padding from being scattered around when taking out the item from the bag.
