[Detailed description of the device]

[0001]

[Industrial applications]

  This device is designed for bags such as handbags, second bags, pouches, and cosmetic bags. About the dog.

[0002]

[Problems to be solved by the device]

  This type of bag is not only practical in functionality, but also has a design in appearance. It is an important factor that determines the product value.

[0003]   Therefore, bags made of cloth, artificial leather, and flexible synthetic resin leather are It was difficult to provide the surface of the material itself with unique irregularities as shape elements. Or because doing so is costly, the creation of that design is mainly On the surface of the bag body, a pattern or pattern is attached by printing etc. separately, or the bag body It is usually done by devising the shape of itself.

[0004]   On the other hand, the inventor of the present invention has previously proposed a balance as described in Japanese Utility Model Publication No. 1-14176. I suggested a dog. The bag according to this prior proposal consists of an outer bag (A) and an inner bag (B). A bag having a double inner and outer bag and a common bag mouth (C) provided in a part of the inner and outer bags. In addition, the outer bag (A) crosses the back surface of the flexible sheet material (1) with each other. By sewing the stretchable thread (2) in the stretched state along several parallels and longitudes, With the contraction of the elastic yarn (2), the lower peripheral portion was squeezed and contracted on the surface of the same material (1). A material material (D) having a large number of discontinuous bulged portions (3) and stretchability. ), The inner bag (B) has a flat cloth and is It is formed in a bag that is sufficiently smaller than the size in the expanded and extended state.

[0005]   And, as described above, the bag according to the prior proposal has the shape of the back body itself. As a material to be made, we use a material with a novel design that is produced by an original method. By using it, it has a unique appearance and feel that is not available in conventional products, Of excellent functionality and practical functionality, easy to manufacture, and can be supplied at a relatively low price A bag could have been provided.

[0006]   However, the above bag has some problems in the shape retention of the bulging folds (3). was there. In other words, the bulging folds are in a relatively fine wrinkled state and have a clean rounded shape. There was a problem that it was difficult to maintain a certain bulge. Especially when external pressure is applied. When stored for a long time in a closed state, the shape restoring force of the bulging folds is lost, The above problems tended to be exacerbated.

[0007]   The present invention has made further improvements to solve the above problems. It is a thing.

[0008]

[Means for Solving the Problems]

  This invention has an outer bag (A) and an inner bag (B) that are formed into an inner and outer double layer, and In the bag where a common bag mouth (C) is provided,   The outer bag (A) has a soft sponge sheet (5) on the back surface of the flexible sheet material (1). Consists of laminated sheets   Stretchable yarns (2) are provided on the back surface of the laminated sheet along a number of longitudinal and parallel lines intersecting with each other. By sewn in the stretched state, the shrinkage of the elastic yarn (2) causes On the material (1) side surface of the laminated sheet, a large number of discontinuous bulgings whose lower peripheral portion is squeezed and contracted On the other hand, it is composed of a material material (D) which is provided with stretchability while forming the elliptical part (3). ,   The inner bag (B) has a flat cloth and is large when the outer bag (A) is in the expanded and extended state. The gist of the bag is that it is formed into a bag that is sufficiently smaller than the size of the bag. It

[0009]   The flexible sheet material (1) is a thin opaque synthetic resin having a glossy surface. It is preferable to use a sheet. This gives the bag an excellent sense of luxury and luxury. Can be obtained.

[0010]

[Embodiment of device]

   Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

[0011]  FIG. 1 and FIG. 2 are partially crushed perspective views of a bag according to the present invention. ) And the inner bag (B) are double-sided, and a common bag mouth (C) is provided in a part of both the inner and outer bags. Have.

[0012]   Outer bag (A) is a flexible and opaque synthetic tree with luster so as to enhance the design effect. A soft sponge sheet (5) is laminated on the back surface of a sheet material (1) made of fat. FIG. 1 with a stretchable material base (D) described below formed using the laminated sheet It is formed in a bag shape as shown in.

[0013]   The above laminated sheet simply comprises the sheet material (1) and the soft sponge sheet (5). They may be superposed or may be adhered using an adhesive or the like.

[0014]   The stretchable material base (D) is, as shown in FIGS. A large number of warp yarns (2), such as covered rubber yarns, cross each other in a grid pattern on the back surface. It is sewn in the stretched state along the latitude line, and the product is produced by contraction of the elastic yarn (2). On the material (1) side surface of the layered sheet, a large number of discontinuous bulgings whose lower peripheral portion is squeezed and contracted The ridge portion (3) is formed on one surface.

[0015]   The inner bag (B) is a plain cloth different from the sheet material (1) of the outer bag (A), C. With a flat cloth, as shown in Fig.2, the outer bag (A) is The size of the outer bag (A) is smaller than the outer bag (A) It is accommodated inside the bag (A) in a slack state (see FIG. 1).

[0016]   Then, the outer bag (A) and the inner bag (B) are integrated at the periphery of the bag mouth (C). It is sewn on and attached with a fastener (4) so that it can be opened and closed freely. Minutes are formed so as to be liberated from each other.

[0017]   The outer bag (A) is made of other sheet material such as lace in order to enhance the design effect. , Knitted fabric, cloth, paper, plastic film and the like. Also, elastic yarn (2) Is sewn along the graticule that intersects in a grid pattern as described above, and also has a design effect. In order to improve the result, for example, one or both of the above-mentioned graticule lines may be partially arranged in parallel. Make different patterns into a checkered pattern and sew elastic yarn (2) along it The bulging folds (3) are partially densely formed on the surface of the layered sheet on the side of the material (1), or It is also possible to form it roughly so as to form a pattern as a whole.

[0018]   Also, the degree of shrinkage of the laminated sheet due to the elastic yarn (2) depends on the bag in which it is used. Depending on the type, it is usually determined within the range that can be expanded by 1.5 to 4 times, but the appearance and feel It is particularly preferable that the surface is contracted so that it can be expanded 2-3 times.

[0019]   The inner bag (B) is formed larger than the outer bag (A) as described above. When using, the inner bag (B) and outer bag (A) are both expanded and contracted according to the size of the contents, When the contents are small, the bag itself shrinks and becomes compact. In the event of a squeeze, the bag itself will expand to provide a practical structure that can be comfortably accommodated. Is. In addition, the same effect can be expected when the inner bag (B) is made of elastic material. . However, it is not limited to these, but the usual products used in conventional products. It also allows the use of inner bags.

[0020]   In addition, although the handle or the shoulder strap is omitted in the examples, they may be used depending on the application. It goes without saying that it is allowed to be attached.

[0021]

[Effect of device]

  As described above, the outer bag (A) of the bag according to the present invention has the bulged pleated portion (3). Because the thick stretchable material base (D) that is clustered on the surface and rich in three-dimensionality is used, the seams are Not only does it not appear on the outside, but it also has a gorgeous and beautiful appearance, as well as shape retention. It is excellent, it does not easily lose its shape, and it has a strength that could not be used with conventional products. Manufacture products that are comparable in shape retention, even when using a weak sheet material In addition, the selection range of materials can be expanded, and the manufacturing cost can be reduced. Also, Since the feel of the is soft and elastic, it absorbs external shocks and accommodates It has the advantage of protecting objects and being light in terms of three-dimensional appearance and thick feel. Furthermore, the stretchable material base (D) is a sponge sheet on the back surface of the sheet material (1). Stretchable thread (2) is sewn along the latitudinal sheet to the laminated sheet Since it can be manufactured by work, it is easy to manufacture and inexpensive to mass-produce. Due to the cushioning properties of the sponge sheet (5), the swollen folds (3) Is formed and maintained in a good state with a fluffy roundness, and it is also very beautiful In addition, the protective effect of the contents is increased, and the external surface is under pressure. Even if it is stored in a state for a long time, it does not lose its shape. Well Also, since the inner bag (B) is formed of a flat cloth, this is the outer bag (A ) Acts so as to close the opening on the inner surface side of the bulging pleated portion (3), and It can be prevented from entering the bulged portion (3). Not only the above inner bag ( B) is formed into a bag that is sufficiently smaller than the size of the outer bag (A) in the expanded and extended state. Therefore, the inner bag (B) can be used to exclusively bear the load of the contents. The outer bag (A) can be prevented from being significantly deformed or deformed even when a large content is put in it. In addition to being able to stop, the outer bag (A) was designed exclusively for the design effect. It is possible to manufacture with the material ground (D).

[0022]  In this way, the appearance and feel are superior to conventional products, not only fashionable but also Bags that are also practical can be mass-produced inexpensively and easily.
