Description

[Technical field]

[0001] The present invention relates to an eco-bag used when purchasing products at various retail stores, etc. [Background technology]

[0002] In recent years, interest in environmental issues has increased, and consumers have begun to bring reusable eco-bags (also known as "foldable eco-bags") when carrying home purchased goods and other items (hereinafter referred to as "goods" in this specification).

[0003] The eco-bag is folded up small and placed in, for example, a pocket of clothing or a bag when not carrying items, and when carrying items, it is taken out, unfolded, the items are stored inside, and carried by hand. For example, an example of such an eco-bag is disclosed in Patent Document 1.

[0004] The eco-bag disclosed in Patent Document 1 has a bag body with an opening formed at the top, capable of storing items inside. A pocket is provided inside the bag body. The pocket is formed so that the bag body can be stored in a small folded state. According to this conventional technology, the bag body can be folded and placed in the pocket to become small, making it less bulky and easier to carry. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2008-23305 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, in the above-mentioned conventional technology, the bag body is made of a relatively thin fabric, which makes the bag body soft and makes it difficult for the eco-bag to stand upright with the opening of the bag body open when it is placed on a loading surface (for example, a luggage sorting table at a retail store).

[0007] In this way, if it is difficult to make the eco bag stand upright with the opening open, the user must open the opening by hand when trying to store items in it, which makes the task of storing items complicated. Therefore, the conventional technology has a problem in that it is difficult to store items in it.

[0008] Additionally, in conventional technology, the bottom of the bag body is soft and has an inconsistent shape, which makes it difficult to carry items that need to be carried steadily (such as sushi or cake, which need to be carried while maintaining their arrangement and shape).

[0009] The present invention has been made in consideration of the above-mentioned circumstances, and its objective is to provide an eco-bag that is easy to carry when folded and provides better operability for storing items than conventional technology. [Means for solving the problem]

[0010] (1) The eco-bag of the present invention, which has been made to solve the above problems, is characterized in that it has a storage section in which an opening is formed on the top surface and an internal space communicating with the opening, the storage section has a bottom surface and a plurality of side surfaces continuous with the bottom surface, and is formed so as to be foldable into a flat surface by overlapping a pair of opposing side surfaces on the bottom surface, and a self-supporting member is arranged on each of the bottom surface and the pair of side surfaces, which allows the opening to be open and the storage section to be self-supporting when the pair of side surfaces are raised. In this case, it is preferable that the self-supporting member is made of an elastic ring-shaped strip, and that the self-supporting members arranged on the bottom surface and the pair of side surfaces are configured to be overlapped with each other and twisted together into an approximately figure-8 shape when folded.

[0011] According to the present invention having the above feature (1), by arranging the self-supporting members on the bottom surface and the pair of side surfaces, the storage section can be made to stand on its own with the opening open when the pair of side surfaces are raised. Since the storage section can stand on its own with the opening open in this way, the user can store items in it without having to hold the opening open with their hands, making it easier to store items.

[0012] Furthermore, according to the present invention, since the pair of side surfaces can be overlapped on the bottom surface and folded into a flat shape, even if the bottom surface and the pair of side surfaces each have a self-supporting member (even if the self-supporting member is arranged in triplicate), there is no significant difference in size when folded compared to when the self-supporting member is a continuous member. Therefore, according to the present invention, even if the bottom surface and the pair of side surfaces each have a self-supporting member, the product is not bulky and is easy to carry.

[0013] In addition, according to the present invention, the storage section can be folded or opened all at once by overlapping the self-supporting members on the bottom and the pair of side surfaces, making it easy to put items in and take them out, and to fold it up after use.

[0014] In addition, according to the present invention, the shape of the bottom surface is maintained by arranging a self-supporting member on the bottom surface, making it easier to carry items that need to be carried stably compared to conventional technologies in which the bottom surface is soft and the shape is not constant.

[0015] (2) Furthermore, in the eco-bag of the present invention described above in (1), each of the pair of sides may be configured so that when the pair of sides are raised, they gradually expand outwardly of the storage section as they move from the bottom side to the opening side.

[0016] According to the present invention having the above feature (2), since each of the pair of side surfaces is provided so as to extend outward from the storage section when the pair of side surfaces are raised, the pair of side surfaces are unlikely to collapse toward the inside of the storage section when the pair of side surfaces are raised. Therefore, it becomes easier to maintain the opening open.

[0017] (3) Furthermore, in the eco-bag of the present invention described above in (1) or (2), at least each of the pair of side surfaces may be provided with a reinforcing cloth that covers each corner of the bottom surface from the side.

[0018] According to the present invention having the above feature (3), the bottom surface and the pair of side surfaces are each reinforced with the reinforcing cloth, which makes it easier for the storage section to stand on its own.

[0019] (4) In the eco-bag of the present invention described above in (1), (2) or (3), the storage section may be provided with a reinforcing cloth on the opening side.

[0020] According to the present invention having the feature as described above in (4), the reinforcing cloth is provided on the opening side, so that the pair of side surfaces can stand independently and stably, and the opening can be easily maintained in an open state.

[0021] (5) Furthermore, in the eco-bag of the present invention described above in (1), (2), (3) or (4), the bottom surface and each of the pair of side surfaces may be formed so that the self-supporting members are freely attachable and detachable.

[0022] According to the present invention having the above feature (5), since the self-supporting members are detachable from the bottom surface and the pair of side surfaces, the self-supporting members can be removed from the bottom surface and the pair of side surfaces, and the eco-bag can be washed. Therefore, the eco-bag for storing various items can be kept clean. Effect of the Invention

[0023] According to the present invention, it is possible to easily carry an eco-bag in a folded state while improving the operability of storing items in the bag compared to the conventional technology. [Brief description of the drawings]

Note that the arrows in the figures indicate the up-down direction, the left-right direction, and the front-rear direction, respectively (the directions of the arrows are only examples).

[0027] 1 to 3, reference numeral 1 indicates an embodiment of an eco-bag according to the present invention. The eco-bag 1 is made of fabric, and as shown in Fig. 1, includes a storage section 2 and a pair of gripping sections 3. Each component of the eco-bag 1 will be described below.

[0028] First, the storage section 2 will be described. 1 to 3 constitutes the main body of the eco bag 1 and is a portion for storing items. The storage section 2 includes a storage section main body 4, a plurality of (three in this embodiment) self-supporting members 5, a first reinforcing cloth 6, and a second reinforcing cloth 7.

[0029] The storage unit body 4 shown in Fig. 1 is formed in a generally box-like shape with an opening 8 on the top surface. The storage unit body 4 has a bottom surface 9, a front surface 10, a rear surface 11 (see Figs. 2 and 3), a left side surface 12, and a right side surface 13, and also has an internal space 14. The internal space 14 is formed to communicate with the opening 8 and to be able to store items therein. Self-supporting members 5 are arranged on the bottom surface 9, the left side surface 12, and the right side surface 13, respectively.

[0030] The front surface 10, the back surface 11, the left side surface 12, and the right side surface 13 correspond to the "plurality of side surfaces" in the claims. The left side surface 12 and the right side surface 13 correspond to the "pair of side surfaces" in the claims.

[0031] The storage section 2 (storage section main body 4) is formed so as to be foldable into a flat shape by overlapping a left side surface 12 and a right side surface 13 on the bottom surface 9. As shown in FIG. 1, the left side surface 12 and the right side surface 13 are provided so as to gradually expand outward from the storage section 2 from the bottom surface 9 side toward the opening 8 side with the left side surface 12 and the right side surface 13 standing up.

[0032] The bottom surface 9, the left side surface 12, and the right side surface 13 are formed so that the self-supporting member 5 can be detachably attached. Although detailed explanation and illustration of the structure that allows the self-supporting member 5 to be detachably attached will be omitted, for example, the bottom surface 9, the left side surface 12, and the right side surface 13 are formed of two layers of fabric, with the inner layer being formed so as to be openable and closable, and the self-supporting member 5 can be inserted and removed between the layers of fabric (otherwise, for example, a structure in which the bottom surface 9, the left side surface 12, and the right side surface 13 each have a pocket formed so as to be able to accommodate the self-supporting member 5 may be adopted).

[0033] The self-supporting member 5 shown in Figs. 1 to 3 is made of a wire that is annular (elliptical) when viewed from above. This self-supporting member 5 is an elastic, bendable, annular strip made of metal that can return to its pre-bent state after bending. The self-supporting member 5 is formed so that the opening 8 is open with the left side surface 12 and the right side surface 13 raised, and the storage section 2 can be kept in a state of being self-supporting on a placement surface (e.g., a luggage sorting table in a retail store) not shown. Note that the material of the self-supporting member 5 is not limited to metal, and may be other materials such as synthetic resin, as long as it is an elastic, bendable annular strip.

[0034] The self-supporting member 5 is formed so that its longitudinal width and lateral width are approximately equal to the longitudinal width and lateral width of each of the bottom surface 9, the left side surface 12, and the right side surface 13. By disposing the self-supporting member 5 on each of the bottom surface 9, the left side surface 12, and the right side surface 13, the planar shapes of each of the bottom surface 9, the left side surface 12, and the right side surface 13 are maintained.

[0035] The first reinforcing cloth 6 and the second reinforcing cloth 7 shown in FIG. 1 are formed of a cloth that is thicker and has more rigidity than the cloth forming the storage section main body 4. The first reinforcing cloth 6 and the second reinforcing cloth 7 correspond to the "reinforcing cloth" described in the claims. The first reinforcing cloth 6 is provided on the opening 8 side. In this embodiment, the first reinforcing cloth 6 is provided on the outer surfaces of the front surface 10 and the back surface 11. The second reinforcing cloth 7 is provided on the bottom surface 9 side. In this embodiment, the second reinforcing cloth 7 is provided on the outer surfaces of the left side surface 12 and the right side surface 13 so as to cover each corner of the bottom surface 9 from the side.

[0036] Next, the pair of gripping parts 3 will be described. The pair of gripping parts 3 shown in FIG. 1 are parts that a user grips when storing and carrying items in the eco bag 1 (storage section 2). In this embodiment, one of the pair of gripping parts 3 is disposed at the left end of the storage section 2, and the other gripping part 3 is disposed at the right end of the storage section 2. right The grip portion 3 is formed so that one end thereof is continuous with the front surface 10 and the other end thereof is continuous with the rear surface 11.

[0037] Next, a method for folding the eco bag 1 according to the present invention will be described. First, with the storage section 2 in a self-supporting state (see FIG. 1), as shown in FIG. 4, the left side surface 12 is tilted in the direction indicated by the arrow B and the right side surface 13 is tilted in the direction indicated by the arrow C, thereby overlapping the left side surface 12 and the right side surface 13 on the bottom surface 9 and folding it into a flat shape. In the folded state, the self-supporting members 5 arranged on the bottom surface 9, the left side surface 12, and the right side surface 13 respectively overlap each other.

[0038] Thereafter, as shown in Fig. 5(a), one end and the other end in the longitudinal direction of the overlapping self-supporting members 5 are twisted as indicated by arrows D and E, respectively, so that the overlapping self-supporting members 5 are twisted into an approximately figure-8 shape (see Fig. 5(b)). Thereafter, the overlapping self-supporting members 5 are folded even smaller (see Figs. 5(c) and 5(d)) and made into an approximately perfect circle (see Fig. 5(e)). Note that Fig. 5 omits the illustration of the multiple (three) overlapping self-supporting members 5 and shows only one.

[0039] As shown in Fig. 6, the folded eco bag 1 is stored in a separate storage bag 15 as indicated by the arrow F. Alternatively, although not specifically shown, for example, a storage pocket may be integrally provided on the inner surface of the storage section main body 4, and the folded eco bag 1 may be stored in this storage pocket. This completes the folding of the eco bag 1. Note that in Fig. 6, the illustration of the fabric surrounding the self-supporting member 5 that constitutes the main body of the eco bag 1 is only a rough depiction.

[0040] When the folded eco-bag 1 is to be used, the self-supporting member 5 returns to its original shape (elliptical) before bending when the eco-bag 1 is unfolded. Then, the left side surface 12 and the right side surface 13 are raised.

[0041] According to the present embodiment described above, the self-supporting members 5 are disposed on the bottom surface 9, the left side surface 12, and the right side surface 13, respectively, so that the storage section 2 can be made to stand on its own with the opening 8 open and the left side surface 12 and the right side surface 13 raised. Since the storage section 2 can be made to stand on its own with the opening 8 open in this manner, when a user tries to store an item in it, the user can store the item in it without having to hold the opening 8 open with his or her hands, making it easier to store the item.

[0042] Furthermore, according to this embodiment, the left side surface 12 and the right side surface 13 can be overlapped on the bottom surface 9 to fold it into a flat surface, so even if the bottom surface 9, left side surface 12, and right side surface 13 each have a self-supporting member 5 (even if there are three self-supporting members 5 in a row), there is no significant difference in size when folded compared to the case where there is a single self-supporting member 5. Therefore, according to this embodiment, even if the bottom surface 9, left side surface 12, and right side surface 13 each have a self-supporting member 5, it is not bulky and is easy to carry.

[0043] In addition, according to this embodiment, the self-supporting members 5 on the bottom surface 9, left side surface 12, and right side surface 13 can be stacked to fold or open the storage section 2 all at once, making it easy to put items in and take them out, and to fold the storage section after use.

[0044] Furthermore, according to this embodiment, the shape of the bottom surface 9 is maintained by arranging the self-supporting member 5 on the bottom surface 9, so that it becomes easier to carry items that need to be carried stably (for example, sushi, cakes, etc., which need to be carried while maintaining their arrangement and shape) compared to conventional technologies in which the bottom surface is soft and the shape is not constant.

[0045] Furthermore, according to this embodiment, the left side surface 12 and the right side surface 13 are provided so as to spread outward from the storage section 2 when the left side surface 12 and the right side surface 13 are raised, so that when the left side surface 12 and the right side surface 13 are raised, the left side surface 12 and the right side surface 13 are unlikely to fall inward from the storage section 2. This makes it easier to maintain the opening 8 open.

[0046] Furthermore, according to this embodiment, the bottom surface 9, the left side surface 12, and the right side surface 13 are reinforced by the second reinforcing fabric 7, so that the storage section 2 can easily stand by itself.

[0047] Furthermore, according to this embodiment, the first reinforcing fabric 6 is provided on the opening 8 side, so that the left side surface 12 and the right side surface 13 stand independently and stably, and the opening 8 can be easily maintained in an open state.

[0048] Furthermore, according to this embodiment, the self-supporting members 5 are detachable from the bottom 9, left side 12, and right side 13, respectively, so that the self-supporting members 5 can be removed from the bottom 9, left side 12, and right side 13, respectively, and the eco-bag 1 can be washed. Therefore, the eco-bag 1 for storing various items can be kept clean.

[0049] Next, the effects of this embodiment will be described. As explained above with reference to Figures 1 to 6, this embodiment has the effect of making the eco bag 1 easy to carry in a folded state while improving the operability of storing items compared to the conventional technology.

[0050] In addition, it is needless to say that the present invention can be modified in various ways without departing from the spirit and scope of the present invention. [Explanation of symbols]
