Description

[Technical Field]

[0001] The present invention relates to a folding bag with an integrated case, in which a case for storing the folded bag is attached integrally to the bag. [Background technology]

[0002] As described in Patent Document 1, there have been conventional bags that can be folded, such as eco-bags, and stored in a storage pouch that is integrally attached to the bag, making the bag small and easy to carry when not in use. In such bags, when the bag is unfolded for use, the storage pouch is usually hidden on the inner side of the bag. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3224700 Summary of the Invention [Problem to be solved by the invention]

[0004] As eco-bags and other items become more popular, people are increasingly seeking not only practical items but also stylish, well-designed items. In response to this, bags are being sold that have designs such as letters, illustrations, characters, patterns, etc. on the outside of the bag, but in order to further increase the appeal of the bag, there is a demand for them to be differentiated from other products in ways other than the design on the outside of the bag.

[0005] This invention was made with an eye on the above-mentioned conventional problems, and its purpose is to provide a new and useful folding bag with an integrated case that can be differentiated from other products and increase the appeal of the bag, in addition to the design of the outer bag surface. [Means for solving the problem]

[0006] The present invention has been made to solve the above-mentioned problems, and provides a foldable bag comprising a pouch-shaped bag made of foldable fabric and a case attached to the outer surface of the bag. The case is box-shaped and comprises a pair of main surface portions, wall portions connecting the respective edges of the pair of main surface portions, and a fastener provided on the wall portion. When the fastener is opened, the pair of main surface portions open like a folding door. When the fastener is closed, the pair of main surface portions can be turned inside out. One of the pair of main surface portions is attached to the outer surface of the bag, or the one main surface portion doubles as the outer surface of the bag. When the fastener is closed, the side of the case opposite to the side attached to the outer surface of the bag becomes the outer surface of the case, and when it becomes the inner surface of the case, it becomes the outer pocket of the bag.

[0007] Preferably, the case is configured in the shape of a flat rectangular box, with a pair of broad surfaces serving as main surfaces. Preferably, the case has fasteners on three wall surfaces, and when used as an outer pocket, it opens like a double door on the left and right. Preferably, both surfaces of the pair of main surface portions of the case and the remaining wall surface portion on which no fasteners are provided are designed surfaces. Preferably, the bag has shape retention properties that allow it to return to its original shape even if bent. [Effects of the Invention]

[0008] The foldable bag with integrated case of the present invention can be used as a storage case for the folded bag or as an outer pocket for the unfolded bag, and the exposed outer surface of the storage case can be used as a design surface. In this way, the case is not only given multiple practical uses, but is also designed to be used as a design element in addition to the outer surface of the bag, thereby differentiating it from other products.

DETAILED DESCRIPTION OF THE INVENTION

[0010] A folding bag with an integrated case 1 according to an embodiment of the present invention will be described with reference to the drawings. In Figures 1 and 2, reference numeral 3 denotes a case. This case 3 has a pair of vertically elongated rectangular wide surface portions 5 and 7, each with four edges connected by wall surface portions 9, forming a flat, vertically elongated rectangular box. A fastener 11 is provided across the top surface portion 9a, one side surface portion 9b, and bottom surface portion 9c of the wall surface portion 9 so as to open continuously on three sides. The fastener 11 is a linear fastener and is made up of a tape, an element (teeth), and a slider (opening / closing part), with the top surface portion 9a, one side surface portion 9b, and bottom surface portion 9c also functioning as a single continuous tape. The base end of the fastener 11 is provided on the bottom surface portion 9c side. When the fastener 11 is opened, the wide surface portions 5 and 7 sandwich the side surface portion 9d and open like a double door.

[0011] The wide surface portion 7 and the side surface portion 9d of the case 3 are made of two overlapping synthetic resin sheets, and have a double-sided surface specification. That is, the surface "A" of the wide surface portion 5, the surface "1" of the side surface portion 9d of the wall surface portion 9, and the surface "B" of the wide surface portion 7 are all made of a single synthetic resin sheet. Also, the surface "C" of the wide surface portion 7 (indicated as "C" on the surface in Fig. 3, etc.) to the surface "2" of the side surface portion 9d of the wall surface portion 9 (indicated as "2" on the surface in Fig. 3, etc.) are also made of a single synthetic resin sheet. All of these outer surfaces have a design surface that can display letters, illustrations, characters, patterns, etc.

[0012] The surface material "B" of the wide surface portion 7 to the surface material "1" of the side surface portion 9d of the wall surface portion 9 is overlapped with the surface material "C" of the wide surface portion 7 to the surface material "2" of the side surface portion 9d of the wall surface portion 9 so as to form a double-sided surface specification, and all edges of the single synthetic resin sheet constituting the surface material "C" of the wide surface portion 7 to the surface material "2" of the side surface portion 9d of the wall surface portion 9 are sewn and integrated with the single synthetic resin sheet constituting the surface material "A" of the wide surface portion 5 to the surface material "1" of the side surface portion 9d of the wall surface portion 9 to the surface material "B" of the wide surface portion 7. The three edges of the overlapped portion are sewn together while sandwiching the edges of the upper surface portion 9a, side surface portion 9b, and lower surface portion 9c, which also serve as the tape of the fastener 11, to form a single piece. The four edges of the outer fabric "A" of the wide surface portion 5 are sewn together to the bag surface portion 13a of the bag 13, sandwiching the edges of the upper surface portion 9a, side surface portion 9b, and lower surface portion 9c, which also serve as the tape of the fastener 11, and are integrated.

[0013] When fastener 11 is closed, wide surface portions 5 and 7 can be turned inside out, and when fastener 11 is closed as shown in Figures 1 and 2, surface "A" of wide surface portion 5, surface "B" of wide surface portion 7, and surface "1" of side surface portion 9d of wall portion 9 form the outer surface of the case. The synthetic resin sheet is made of polyester and has the ability to return to its original shape even after being bent, making it difficult for the case to lose its shape.

[0014] The reference numeral 13 denotes a tote-shaped bag. This bag 13 is made by sewing, and is a horizontally elongated flat rectangular bag with a gusset and an opening at the top. In addition, arch-shaped handles 15, 15 made of strips are attached to the bag opening sides of the pair of bag surfaces 13a, 13b, respectively. This bag 13 has an outer bag surface "○" on the bag surface portion 13a (a large number of ○, ○, ○... are displayed on the surface, as in Figure 3, etc.) and an outer bag surface "△" on the bag surface portion 13b (a large number of △, △, △... are displayed on the surface, as in Figure 4, etc.), which are each designed surfaces that can display letters, illustrations, characters, patterns, etc. The bag 13 is made of nylon fabric that is easy to fold.

[0015] The case 3 is attached to the outer bag surface "◯" of the bag surface portion 13a of the bag 13 by sewing as described above. As described above, in case 3, the outer material "B" of the wide surface portion 7 to the outer material "1" of the side surface portion 9d of the wall surface portion 9 are overlapped with the outer material "C" of the wide surface portion 7 to the outer material "2" of the side surface portion 9d of the wall surface portion 9, but the back side of the outer material "A" of the wide surface portion 5 that is left unoverlapped is overlapped with the outer bag surface "○", and the four edges of the outer material "A" of the wide surface portion 5 are sewn together to form one piece, so that the back side of the outer material "A" of the wide surface portion 5 is completely hidden.

[0016] In case 3, wide surface portion 5 is located at approximately the center of bag surface portion 13a, and when fastener 11 is closed, wide surface portion 7 overlaps wide surface portion 5. When fastener 11 is opened and wide surface portion 7 is raised, wide surface portions 7 and 5 open like a double door. At this time, side surface portion 9d of wall portion 9 extends vertically between wide surface portions 7 and 5.

[0017] Case-integrated foldable bag 1 is configured as described above, and when bag 13 is folded, it can be stored in case 3, which becomes a flat box when closed with fastener 11, as shown in Figures 1 and 2. In this case, the outer surface of case 3 is made up of surface material "A" of wide surface portion 5, surface material "1" of side surface portion 9d of wall portion 9, and surface material "B" of wide surface portion 7. On the other hand, when bag 13 is unfolded and case 3 is closed with fastener 11, as shown in Figures 3 and 4, case 3, which has become a flat box shape, is positioned approximately in the center of bag surface portion 13a of bag 13, and forms an outer pocket with the base end of fastener 11 facing downward. At this time, the outer surface of case 3 is composed of outer surface "C" of wide surface portion 7 and outer surface "2" of side surface portion 9d of wall surface portion 9. That is, when the outer surface "A" of the wide surface portion 5 of the case 3 is closed with the fastener 11, it becomes the outer surface of the case, and becomes a storage case for the bag 13, and when it becomes the inner surface of the case, it becomes an outer pocket for the bag 13.

[0018] Since the base end of the fastener 11 is located on the lower side, the fastener 11 can be partially opened and closed while carrying the bag 13 to take out small items stored therein or to store them back in. Furthermore, as mentioned above, the outer surfaces "C" and "2" of the case 3 can be used as design surfaces to display letters, illustrations, characters, patterns, etc., and therefore become part of a single large design surface that is connected to the bag surface portion 13a of the bag 13.

[0019] When the fastener 11 is opened from the state shown in Figures 3 and 4 and the wide surface portion 7 is raised to open like a double door in a flat state, the wide surface portion 5, side surface portion 9d, and wide surface portion 7 of the case 3 overlap the bag surface portion 13a of the bag 13 as shown in Figures 5 and 6. The wide surface portion 5 is connected to the bag surface portion 13a, but the other portions of the bag surface portion 13a can be separated from the wide surface portion 5 and folded. From the state shown in FIGS. 5 and 6, the bag 13 can be folded into a larger size while reducing the folded surface so as to fit within the length and width dimensions of the case 3.

[0020] Specifically, as shown in Fig. 6, the bag 13 is completely unfolded with the case 3 facing backwards, with the bag surface portions 13a and 13b overlapping, and the sheet-like bag 13 is then divided horizontally into three sections along the boundary where the wide surface portion 5 is joined. As shown in Figs. 7 and 8, the two sides with larger widths at both ends are folded upward and in half, and the folded sides are then folded upward and sequentially back toward the center, resulting in a partially overlapping state at the center. This reduces the width of the bag 13 so that it fits inside the case 3. Next, the protruding portions at the top and bottom of the case 3 are folded back sequentially from the bottom toward the center, as shown in Fig. 9. Finally, the handles 15, 15 are folded in.

[0021] As a result, the bag 13 is folded onto the wide surface portion 5. When the wide surface portion 7 is placed over the wide surface portion 5 from above and closed with the fastener 11, the state shown in FIGS. 1 and 2 is obtained. Conversely, if fastener 11 is opened from the state shown in Figures 1 and 2, folded bag 13 will come out as shown in Figure 9, and by unfolding it, bag 13 will be usable as shown in Figures 3 and 4, and the wide surface portion 7 on the case 3 side can be turned inside out and closed with fastener 11 to become an outer pocket.

[0022] The above describes in detail the embodiment of the present invention, but the specific configuration is not limited to this embodiment, and design changes that do not deviate from the gist of the present invention are also included in the invention. For example, the materials and shapes of the case 3 and bag 13 are not limited to those described in the above embodiments, as long as the functions envisioned for constituting the invention are guaranteed.
