Description

  The present invention relates to a bag with a mount and a case with a built-in bag.

  Conventionally, various gusset bags are provided as bags that can be three-dimensionally expanded from a folded state. However, this type of gusset bag has a problem in that stability and independence are poor unless the bottom is widened and flattened. Moreover, the bottom part folded by gusset was folded inside the bag at the time of storage, and when it was unfolded, it became a boat-like shape as shown in FIG. As shown in FIG. 5B, when the bottom portion has a rectangular shape, both end portions Y of the bag form a rectangular side surface portion, and the boundary between the side surface portion and the bottom portion is unclear.

  In order to achieve stability and self-supporting in an unfolded state, the mount may be integrated with the bottom of the gusset bag, but it is difficult to manufacture the gusset bag with the mount installed. Even if it is possible to manufacture a gusset bag integrally including a mount, such a gusset bag is difficult to fold and does not fit.

  Regarding the invention of the present application, a prior art search was conducted by Property Co., Ltd. However, there is no prior art document that affects the patentability of the present invention.

  Embodiments of a bag with a mount and a case with a built-in bag according to the present invention will be described below with reference to the accompanying drawings.

(Sack with mount, see Figs. 1-3)
A bag with a mount, which is an embodiment of the present invention, includes a plastic bag 10 shown in FIG. 1 and a mount 20 shown in FIG.

  The plastic bag body 10 is a conventionally known gusset bag in which a gusset fold portion 11 is formed in a bottom portion 10a and a side portion 10b is attached or melted. A fastener 15 is attached to which the opposing concave portion 16 and convex portion 17 can be fitted / removed.

  In the gusset fold 11, hook and loop fasteners 12 are attached to the four corners exposed to the bottom when opened (see FIG. 2) with an adhesive or the like. The state in which the gusset folds 11 are folded is as shown in FIG. 1, and the hook and loop fasteners 12 are positioned facing each other inside the folded gusset folds 11.

  On the other hand, the mount 20 is made of, for example, cardboard, and a surface fastener 21 that engages with the surface fastener 12 is attached with an adhesive or the like at a position facing the surface fastener 12 when the gusset folding portion 11 is opened. ing.

  Usually, the bag 10 in the state shown in FIG. 1 and the mount 20 shown in FIG. 3 are prepared in a one-to-one combination. When the bag body 10 is used, first, the gusset folding portion 11 is opened, and the bottom portion 10a is flattened so that the hook-and-loop fasteners 12 are located at the four corners. Then, the surface fastener 12 is engaged with the surface fastener 21 on the mount 20.

  As a result, the bottom 10a is reinforced with the mount 20, and a hard flat mountable bag is obtained. When the hook and loop fasteners 12 and 21 are engaged with each other, the bag body 10 is self-supporting in a stable state. Accordingly, it is easy to store and take out articles from the bag body 10. Moreover, what is necessary is just to unite the bag body 10 and the base_sheet | mounting_paper 20 at the time of use, and the complicated manufacturing process which incorporates the base_sheet | mounting_paper 20 in the bag body 10 is unnecessary, and even if one side is damaged, it can replace | exchange.
