Therefore, an object of the present invention is to provide a container such as a bag or a case in which the body and the bottom can be easily connected to the gusset to reduce the manufacturing cost.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a container such as a bag or a case of the present invention is formed by bending a sheet member 1 to form a body 2 and a bottom 3 in series, and fitting the middle gusset 4 and its outer surface portion. The outer gusset 5 to be worn is formed, and the outer gusset 5 is fitted to the middle gusset 4 while the edge portion 7 of the sheet member 1 is wrapped around and abutted around the frame 6 of the middle gusset 4 The edge portion 7 of the sheet member 1 is sandwiched between the frame portion 6 of the gusset 4 and the peripheral wall portion 8 of the outer gusset 5.

[0005]

[Action]

 When the outer gusset 5 is simply fitted to the middle gusset 4 while the edge portion 7 of the sheet member 1 is wound around and abutted around the frame 6 of the middle gusset 4, the outer gusset 5 of the middle gusset 4 and the outer The edge portion 7 of the sheet member 1 is sandwiched between the peripheral wall portion 8 of the gusset 5 and the body 2, the bottom 3, the middle gusset 4 and the outer gusset 5 are simply and integrally connected.

[0006]

【Example】

 Embodiments will be described below with reference to the drawings. First, a sheet member 1 made of a synthetic resin such as polypropylene is bent to form a body 2 and a bottom 3 in series. In addition, the rear body portion 20 of the body 2 is further provided with a heaven 9 and a lid 10 in series, and a handle 11 is attached to the heaven 9, and the front body portion 12 and the lid 10 of the body 2 are mutually connected. Detachable fasteners 13 and 14 are attached. In the body 2 of the seat member 1, a plurality of small holes 15 are formed at regular intervals in the edge portions 7 on both sides of the front body portion 12 and the rear body portion 20, respectively. Next, the gusset is composed of a middle gusset 4 and an outer gusset 5 fitted to the outer surface of the gusset, both of which are molded by hardness plastic. The middle gusset 4 has a frame portion 6 along its peripheral edge, and projections 16 are provided on the front surface and the rear surface of the frame portion 6 at regular intervals. The middle gusset 4 is provided with a bulging portion 17 on the inner surface side, and an opening 18 is provided on the upper surface of the bulging portion 17. The outer gusset 5 has a peripheral wall portion 8 that overlaps the outer surface side of the frame portion 6 of the middle gusset 4, and a plurality of recesses 19 are provided in the inner surface portions of the front surface and the rear surface thereof at regular intervals. The sheet member 1 has the edge portions 7 on both sides thereof wound around the outer surface of the frame portion 6 of the center gusset 4 and brought into contact therewith, and the projection 16 is fitted into the small hole 15. In a state where the end edge portion 7 of the sheet member 1 is wrapped around and abutted on the outer surface of the frame portion 6 of the middle gusset 4, the outer gusset 5 is attached to the outer surface portion of the middle gusset 4 by surrounding the peripheral wall portion 8 with the frame portion 6 of the middle gusset 4. The projection 16 of the middle gusset 4 penetrating the small hole 15 of the seat member 1 is fitted in the recess 19 provided in the outer gusset 5. Therefore, the outer gusset 5 and the middle gusset 4 are in a locked state, and inadvertent disassembly is prevented. In addition, the edge portion 7 of the sheet member 1 is sandwiched between the frame portion 6 of the middle gusset 4 and the peripheral wall portion 8 of the outer gusset 5, and is inserted into the small hole 15 provided in the edge portion 7 of the sheet member 1. Since the projection 16 of the switch 4 is fitted, the seat member 1 is prevented from being pulled out. The opening 18 in the bulging portion 17 provided on the inner surface side of the middle gusset 4 can be used for inserting a clip of the writing instrument to lock the writing instrument.

[0007]

[Effect of the device]

 The present invention is as described above, and the outer gusset 5 is simply fitted to the middle gusset 4 in a state where the edge portion 7 of the sheet member 1 is wound around and abutted around the frame portion 6 of the middle gusset 4. Then, the edge portion 7 of the sheet member 1 is sandwiched by the frame portion 6 of the middle gusset 4 and the peripheral wall portion 8 of the outer gusset 5, and the middle gusset 4 and the outer gusset 5, the body 2 and the bottom 3 are connected. As a result, the work can be significantly simplified and the cost can be reduced as compared with the conventional method of connecting by means such as sewing. Further, as in the embodiment, the small hole 15 is provided in the edge portion 7 of the sheet member 1, the projection 16 that is fitted in the small hole 15 is provided in the middle gusset 4, and the recess 16 in which the projection 16 is fitted in the outer gusset 5 is provided. The provision of 19 has the effect of further strengthening the combined state of the three. Further, by providing the bulging portion 17 and the opening portion 18 on the inner surface portion of the middle gusset 4 as in the embodiment, it is possible to obtain the convenience of being able to hang a writing instrument or the like.
