Description

[Detailed description of the invention] This invention closes the bottom opening of the body with a bottom member made of rubber or synthetic resin material into a dish shape using a mold, and also inserts an inner bottom plate into the body. This relates to a novel bag in which the material and the inner bottom plate are integrated with each other using rivets or adhesives, and the peripheral wall of the bottom member is sewn to the lower peripheral part of the body, and as shown in FIGS. In the embodiment shown in FIG. 2, a dish-shaped bottom member 1 is constructed by injection molding a rubber material.
to close the bottom opening of the trunk 2 made of cloth or the like, and the lower edge of the trunk 2 is bent inward around the upper surface of the bottom member 1, and a hard inner bottom plate 4 is inserted into the trunk 2. Inset bottom member 1
The bent portion 3 of the lower edge of the body 2 is sandwiched between the inner bottom plate 4 and the bottom member 1, and the bottom member 1 and the inner bottom plate 4 are integrated with studs 5 to form the bottom member 1.
The peripheral wall 6 of the body part 2 is sewn to the lower side of the body part 2. In the embodiment shown in FIG. It is attached to the bottom opening of the

In addition, in the present invention, foams such as rubber and synthetic resin may be used as the material for the bottom member, and when molding the bottom member, the above-mentioned injection molding, compression molding, transfer molding,
Of course, suitable molding methods such as thermoforming, foam molding, casting, and tape molding can be used.

The present invention forms a dish-shaped bottom member by molding a rubber material like a diagonal, and this bottom member closes the bottom opening of a body made of fabric, etc., and the lower edge of this body is located around the top surface of the bottom member. Then, bend it inward, fit a hard inner bottom plate into the body, sandwich the new curved part of the lower edge of the body between this bottom member and the inner bottom plate, and attach the bottom member and the inner bottom plate with rivets. The main feature is that the peripheral wall of the bottom member is integrated and sewn to the lower side of the trunk, so not only can a strong bag with significantly reinforced bottom parts be obtained, but the manufacturing process is also similar to known bottom-reinforced bags. It has various effects such as being extremely simple compared to other methods.
