Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a bag used for leisure.

[0002]

[Prior art]

 Conventionally, a bag with a shoulder belt has been introduced, for example, in Japanese Utility Model Publication No. 58-40863. Since this bag with a shoulder belt is constructed by attaching a narrow shoulder belt made of a soft material, when the shoulder belt is lifted, the shoulder belt 4'is made up of the bag body and the lid as shown in FIG. There was a defect that the bag was deformed by pressing 2'and the appearance was deteriorated.

[0003]

[Problems to be solved by the device]

 A problem to be solved is that when a shoulder bag is provided on a flexible bag, the shoulder belt presses the bag body and the lid to deform the bag, resulting in a poor appearance.

In view of the above-mentioned drawbacks, the object of the present invention is to prevent deformation of the bag body due to pressing of the shoulder belt, and also to prevent rattling of the lid body by pressing the collar portion of the lid body against the bag body by the support piece. It is to propose a bag that can.

[0005]

[Means for solving the problem]

 In order to achieve such an object, the present invention provides a bag having flexibility and a shoulder belt, in which a lid body having a flange portion on the periphery is provided on the upper portion of the bag body, and the bag body is provided on the left and right sides of the bag body. A gist is that a supporting piece wider than the shoulder belt is provided, the shoulder belt is attached to the supporting piece, and the supporting piece presses the flange portion of the lid when the bag body is lifted by the shoulder belt. To do.

[0006]

[Action]

 When the bag is used, when the bag body 1 is lifted by the shoulder belts 4, the left and right support pieces 3 press the flange portions 2b on the periphery of the lid body 2 from both sides, and the bag body 1 is lifted. At this time, the flange portion 2b is pressed against the bag body 1 by the left and right support pieces 3 formed in a triangular shape wider than the shoulder belt 4.

FIG. 5 is a front view of the holding piece, FIG. 5 is an exploded perspective view of a heat-deformable synthetic resin heat insulating plate and a flexible decorative sheet in the lid manufacturing process, and FIG. 6 is an explanatory cross section of a mold in the lid manufacturing process. A side view and FIG. 7 are plan views of the bag.

1 to 3, the bag includes a bag body 1, a lid body 2, a support piece 3 fixed on both left and right sides of the bag body 1, a shoulder belt 4 attached to both support pieces 3 and an inner lid 5. It is composed of. The bag body 1 is formed by sandwiching a synthetic resin heat insulating plate 8 between waterproof sheets 6 and 7. The bag body 1 has an opening 1a on the upper side, and the lid body 2 and the inner lid 5 are fixed to the rear side of the opening 1a by a hinge portion. A chag 9 is attached around the opening 1a of the bag body 1 and around the inner lid 5. Similar to the bag body 1, the inner lid 5 is formed by sandwiching a synthetic resin heat insulating plate 8 between waterproof sheets 6 and 7.

As will be described later, the lid body 2 is formed of a heat-deformable synthetic resin heat insulating plate 10 such as ethylene vinyl acetate foam, and flexible decorative sheets 11 and 12 such as nylon woven cloth. There is. The lid 2 has a curved top plate portion 2a and a flange portion 2b integrally formed on the periphery thereof, and an edge tape 13 is sewn on the edge of the flange portion 2b. The synthetic resin heat insulating plate 10 of the lid 2 is deformed by heat and pressure to integrally form a top plate portion 2a and a flange portion 2b. The sheets 11 and 12 are also provided so as to match the shape of the synthetic resin heat insulating plate 10. Therefore, the decorative sheets 11 and 12 do not have folds or stitch marks at the corners of the lid body.

3 and 4, the support piece 3 has a plurality of divided thick synthetic resin materials 16 as a core material sandwiched between flexible decorative sheets 14 and 15 such as nylon woven cloth. It has a wider triangular shape than the shoulder belt 4. The support piece 3 is formed of a thick synthetic resin material 16 as a core material into a plate shape that is difficult to bend. The lower side 3a of the support piece 3 is fixed to the left and right side surfaces of the bag body 1. A ring 17 is fixed to the upper side 3b of the support piece 3, and the end of a U-shaped shoulder belt 4 is attached to the ring 17. Pockets 18 are provided on the front side and both sides of the bag body 1. A belt 19 and a stopper 20 are provided on the bag body 1 and the lid body 2.

When the lid 2 is manufactured, as shown in FIG. 5, adhesive sheets are applied to the upper and lower surfaces of the heat-deformable synthetic resin heat insulating plate 10, and the decorative sheets 11 and 12 having flexibility, respectively. As shown in Fig. 6, it is bonded and heat is applied by sandwiching it between the molds 21 and 22, and the curved top plate part 2a of Fig. 1 to Fig. 3 and the flange part 2b are deformed by heat and pressure by heat and pressure deformation. The possible synthetic resin heat insulating plate 10 and the decorative sheets 11 and 12 having flexibility are integrally formed seamlessly. Further, the synthetic resin heat insulating plate and the decorative sheet can be attached together at the time of heat and pressure deformation without using an adhesive. Moreover, the surface of the lid 2 having the top plate portion and the collar portion formed by the above-mentioned heat and pressure deformation is covered with the decorative sheet 11 without wrinkles so as to match the top plate portion and the collar portion, and the back surface is also the same. Covered with makeup sheet 12 without wrinkles.

When the bag body 1 is lifted by the shoulder belt 4 when the bag is used, the left and right support pieces 3 press the brim portions 2b on the periphery of the lid body 2 from both sides, and the bag body 1 is Can be lifted. At this time, the flange portion 2b is pressed against the bag body 1 by the left and right support pieces 3 formed in a triangular shape wider than the shoulder belt 4.

When the bag is constructed as described above, the bag body 1 can be lifted while pressing the flange portions 2b of the lid body 2 from both sides by the wide left and right supporting pieces 3 which are plate-shaped and are not easily bent. The bag is prevented from being deformed due to the pressing of the shoulder belt, so that the bag has a good appearance, and the flange portions 2b of the lid body 2 are pressed against the bag body 1 by the left and right support pieces 3 so that the lid body 2 is loose. It can be prevented.

In the above description, the thick synthetic resin material 16 of the core material of the support piece 3 is illustrated as being vertically sandwiched, but it may be horizontally sandwiched. In the above explanation, the synthetic resin heat insulating plate 10 is deformed by heat and pressure to integrally form the top plate portion 2a and the collar portion 2b. However, like the bag body 1 and the inner lid 5, a waterproof sheet is used. You may use what formed the synthetic resin heat insulation board in between.

[0015]

[Effect of device]

 As described above, according to the present invention, since the bag main body is lifted while pressing the flange portions of the lid body from both sides with the wide left and right support pieces, the bag is prevented from being deformed and has a good appearance, and the left and right support pieces are also provided. As a result, it is possible to provide a bag that is excellent in practical use such that the flange portion of the lid body is pressed against the bag body and the lid body is prevented from rattling.
