DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a rectangular flattened state which can be carried when a storage object is not stored, and a triangular pyramid-shaped three-dimensional tetrahedron when storing the storage object. An object of the present invention is to provide a bag body that can be deformed into a form to secure a wide accommodation space for accommodating an object.

[0002]

2. Description of the Related Art Conventionally, a rectangular bag comprising a front cloth portion and a back cloth portion is the most versatile bag shape and is widely used. This rectangular bag has the simplest structure,
This has the advantage that the production cost is reduced and that it can be flattened and compact when not in use. Of these bags, particularly inexpensive and simple shapes, those having a structure in which a bottom portion is sewn in a straight line, an upper end portion is formed in an opening, and a hand-held portion such as a string is provided in the opening, are often used. I have.

[0003] However, as shown in FIG. 6, the conventional rectangular bag has a large bottom because the bottom portion a is closed linearly and the bottom portion is narrow when the articles are put in. When the object is stored, the opening b does not close, or if you try to forcibly close the mouth, the stored object is pressed by the front and back cloth materials on the front and back of the bag, deformed or wrinkled. It was easy to do.

Accordingly, such a rectangular bag can be conveniently accommodated and carried when carrying rectangular articles such as books, notebooks, and rectangular thin housings. When spherical objects such as fruits such as melons or seafood such as turtles, or cloth products such as swimwear and towels are stored, the bag only expands in a tubular shape while the inside of the bag remains rectangular. There is a problem that the object is pressed down and the contents are easily damaged or wrinkled.

In addition, the conventional rectangular bag has a problem that it is inferior in stability because it has a shape close to a flat shape when the amount of contents is small, and it is easy to fall down when placed on the floor. Was.

[0006] On the other hand, as a method of using the bag, it is not only necessary to carry an object in the bag, but also, for example, in the case of excursions or sports such as swimming, diving or camping, when drying a swimsuit or towel, the wind is used. There is a usage method in which a wet swimsuit or a towel is put in a breathable bag formed of a net or the like and hung to dry it out so as not to be blown. In this case, according to the conventional rectangular bag, even though the bag is formed of a net having air permeability, the front and back cloth portions of the bag press the swimsuit or the like put in the bag and compress it. When drying,
There is a problem that the wind does not sufficiently pass through the inside of a swimsuit or a towel and the drying is delayed.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been made in consideration of the above problem. It can be handled in a flat shape in the same manner as above, and when storing items such as clothes such as fruits or swimwear, a sufficient storage space is secured inside the bag body so that the items are not pressed down. It is another object of the present invention to provide a bag in which a bottom surface is formed on the lower surface of the bag so that the bag can be stably supported on a floor or the like.

Further, according to the present invention, by forming the bag with a net such as a net, a wet bathing suit or a towel in a sea bathing or campsite is put in the bag.
An object of the present invention is to provide a bag body that can ensure drying of a swimsuit or the like at an early stage while ensuring sufficient internal air permeability.
