Description

Technical Field

[0001] The present invention relates to a bag, particularly a bag in which the capacity of the storage area remains the same while the shape of the storage area is variable.

Background Art

[0002] As disclosed in Patent Document 1, conventionally, a multi-functional bag that can be used in multiple forms has been proposed.

[0003] The multi-functional bag includes a main body sheet formed in a rectangular planar shape, a plurality of handles formed in a strip shape and extending from the upper edge of the main body sheet, a plurality of fasteners attached to two side edges facing each other in the left-right direction of the main body sheet, and a fastener for joining the side edges on the same side when the main body sheet is folded in half in the vertical direction. It has a first form that can be used as a mat by spreading the main body sheet to the maximum, a second form that becomes a bag with a single large storage area by folding the main body sheet in half in the left-right direction and closing the fastener, and further, by folding it in half in the vertical direction and connecting the fasteners on the left and right edges, it can be deformed into a third form that becomes a bag with two storage areas.

[0004] However, in the third form, since it only folds the bag in the second form in half to secure two storage areas, the capacity of each storage area becomes half of the capacity of the storage area in the second form.

[0005] That is, as the size of the items that can be stored in the bag, the inner dimensions of the bag in the second form are the largest size, and in the bag in the third form, only items with a size of less than half of the items that can be stored in the bag in the second form can be stored.

[0006] Bags for storing daily necessities such as books and clothes are more convenient to use when they have a shape that is slightly wider in width than in height when viewed from the front. On the other hand, long and slender items such as flower bouquets and yoga mats cannot be properly stored because they protrude from the bag due to their length even if one tries to store them in such a bag. Therefore, it is necessary to prepare more vertically long or wide bags. Thus, it was necessary to prepare a plurality of bags according to the shape of the items to be stored.

Summary of the Invention

Problems to be Solved by the Invention

[0008] The present invention has been made in view of the above problems, and an object thereof is to provide a bag in which the shape of the storage area is variable while keeping the capacity of the storage area as it is.

Means for Solving the Problems

[0009] In order to achieve the above object, the bag according to the present invention includes a rectangular main body sheet provided with a first side portion and a second side portion that constitute the longer pair of opposite sides among the two pairs of opposite sides of different lengths, and a third side portion and a fourth side portion that constitute the shorter pair of opposite sides around the periphery thereof; a first connecting portion that can be connected so as to close the first side portion that is bent in accordance with the bending of the main body sheet when the main body sheet is folded in half at the center such that the third side portion and the fourth side portion face each other; a second connecting portion that can be connected so as to close the second side portion; and a third connecting portion that can be connected so as to close the third side portion that is bent in accordance with the bending of the main body sheet when the main body sheet is folded in half at the center such that the first side portion and the second side portion face each other. The first connecting portion and the second connecting portion are configured to be able to be connected to each other when the main body sheet is folded in half at the center such that the first side portion and the second side portion face each other. This is the gist of the present invention.

[0010] According to the above configuration, the bag in the first form configured by folding the main body sheet in half at the center such that the third side portion and the fourth side portion face each other, and the bag in the second form configured by folding the main body sheet in half at the center such that the first side portion and the second side portion face each other only differ in the way of folding the same main body sheet. Therefore, the capacity of the storage area remains the same, and since the main body sheet is rectangular with a long side and a short side, its shape can be changed. That is, the shape of the storage area can be changed while keeping the capacity of the storage area unchanged.

[0011] Note that by spreading out the main body sheet without connecting the first side portion, the second side portion, and the third side portion, it can be used as a mat such as a leisure sheet.

[0012] In the bag according to the present invention, the first connecting portion, the second connecting portion, and the third connecting portion are each composed of a wire fastener. The wire fastener is composed of a first tape with an element having a slider, a box bar, and a box, and a second tape with an element having a butterfly bar. When the main body sheet is folded in half at the center so that the third side portion and the fourth side portion face each other, one of the first tape or the second tape on the side connected to the third side portion is such that the box bar and the box or the butterfly bar are arranged closer to the folded portion of the main body sheet. It is provided in a manner where the other of the second tape or the first tape on the side connected to the fourth side portion is arranged such that the butterfly bar or the box bar and the box are arranged closer to the folded portion of the main body sheet. The second connecting portion is provided such that when the main body sheet is folded in half at the center so that the third side portion and the fourth side portion face each other, one of the second tape or the first tape on the side connected to the third side portion is such that the butterfly bar or the box bar and the box are arranged closer to the folded portion of the main body sheet. The other of the first tape or the second tape on the side connected to the fourth side portion is provided in a manner where the box bar and the box or the butterfly bar are arranged closer to the folded portion of the main body sheet. The third connecting portion is provided such that when the main body sheet is folded in half at the center so that the first side portion and the second side portion face each other, one of the first tape or the second tape on the side connected to the first side portion is such that the box bar and the box or the butterfly bar are arranged closer to the corner connected to the first side portion. The other of the second tape or the first tape on the side connected to the second side portion is provided in a manner where the butterfly bar or the box bar and the box are arranged closer to the corner connected to the second side portion. It may be characterized by this.

[0013] As a specific embodiment that can easily perform the connection and disconnection of the first connecting portion, the second connecting portion, and the third connecting portion, the above-described configuration can be adopted.

[0014] In the bag according to the present invention, it may be characterized in that the main body sheet is made of a material having waterproof property on at least the front or back surface.

[0015] According to the above configuration, it is possible to realize a bag that can accommodate wet items in the accommodation area or items that should not be wetted in the accommodation area. Further, when used as a mat such as a leisure sheet, it is possible to prevent moisture on the ground where the mat is laid from being transmitted to the front surface of the main body sheet.

[0016] In the bag according to the present invention, when the main body sheet is folded in half at the center such that the third side portion and the fourth side portion face each other on the front surface of the main body sheet, an opening directed toward the fourth side portion is provided on the surface continuous with the fourth side portion, a pocket that can be accommodated in a state where the back surface of the main body sheet is inside, a flap provided on the side opposite to the portion constituting the opening among the sheets constituting the pocket, and a fastener capable of engaging the back surface of the flap and the front surface of the pocket may be provided.

[0017] According to the above configuration, when the bag is not in use, it can be folded and fixed in a compact shape by fixing the flap and the pocket with a fastener.

[0018] In the bag according to the present invention, a pair of loop-shaped handles provided so as to extend outward from each of the third side portion and the fourth side portion on the outer surface of the main body sheet, and among the pair of handles, the handle on the side extending outward from the fourth side portion of the main body sheet is provided with an engaging portion and is configured to be engageable with an engaged portion provided on the front surface of the main body sheet.

[0019] According to the above configuration, since the bag has handles, it is easy to carry. Among the pair of handles, the handle on the side extending outward from the fourth side portion of the main body sheet is provided with an engaging portion and is configured to be engageable with an engaged portion provided on the surface of the main body sheet. Therefore, when the bag is in the second form configured by folding the main body sheet in half at the center such that the first side portion and the second side portion face each other, the unnecessary handle can be fixed. At this time, it is preferable that the pair of handles are configured to be adjustable in length, and the ease of carrying the bag can be easily changed by adjusting the length of the handle.

The pocket 33 is attached to the surface of the main body portion 20 by a mode in which a sheet of the same material as the main body portion 20 is sewn or pasted on three sides of the surface of the main body portion 20, and has an opening 34 on the side of the handle 30.

[0023] The main body part 20 is composed of a main body sheet 20A as shown in FIG. 2. The main body sheet 20A is a rectangular sheet having a first side part 21 and a second side part 22 that constitute the longer pair of opposite sides among the two pairs of opposite sides of different lengths, and a third side part 23 and a fourth side part 24 that constitute the shorter pair of opposite sides on the periphery. In the present embodiment, the dimension of the long side of the main body sheet 20A is 85 cm, and the dimension of the short side is 50 cm.

[0024] The main body sheet 20A is composed of a high-elasticity oxford cloth (600d) on the surface and polyvinyl chloride on the back surface. Note that the surface may be other fabrics. The back surface is not limited to polyvinyl chloride, but is preferably a waterproof material such as nylon, polyester, or polyethylene.

[0025] The main body sheet 20A is provided with a first connecting part 41, a second connecting part 42, and a third connecting part 43 on three sides of the periphery.

[0026] The first connecting part 41 is configured to be able to connect so as to close the first side part 21 that is bent according to the bending of the main body sheet 20A when the main body sheet 20A is folded in half at the center such that the third side part 23 and the fourth side part 24 face each other.

[0027] The second connecting part 42 is configured to be able to connect so as to close the second side part 22 that is bent according to the bending of the main body sheet 20A when the main body sheet 20A is folded in half at the center such that the third side part 23 and the fourth side part 24 face each other.

[0028] The third connecting part 43 is configured to be able to connect so as to close the third side part 23 that is bent according to the bending of the main body sheet 20A when the main body sheet 20A is folded in half at the center such that the first side part 21 and the second side part 22 face each other.

[0029] Note that the first connecting portion 41 and the second connecting portion 42 are configured such that when the main body sheet 20A is folded in half at the center with the first side portion 21 and the second side portion 22 facing each other, they can connect the first side portion 21 and the second side portion 22 that face each other, respectively.

[0030] Specific embodiments of the first connecting portion 41, the second connecting portion 42, and the third connecting portion 43 will be described.

[0031] In the present embodiment, the first connecting portion 41, the second connecting portion 42, and the third connecting portion 43 are composed of wire fasteners, preferably water-stop (or water-repellent) fasteners.

[0032] As shown in FIG. 3, the wire fastener has a general structure. Specifically, it is composed of a first tape 51 with an element having a slider 53, a box bar 54, and a box 55, and a second tape 52 with an element having a butterfly bar 56.

[0033] In the following description, for the purpose of facilitating the discrimination of the first tape 51 and the second tape 52 used for each of the first connecting portion 41, the second connecting portion 42, and the third connecting portion 43, those used for the first connecting portion 41 are denoted as the first tape 51A and the second tape 52A, those used for the second connecting portion 42 are denoted as the first tape 51B and the second tape 52B, and those used for the third connecting portion 43 are denoted as the first tape 51C and the second tape 52C.

[0034] Returning to FIG. 2, when the main body sheet 20A is folded in half at the center with the third side portion 23 and the fourth side portion 24 facing each other, the first connecting portion 41 is provided in such a manner that the first tape 51A is on the side continuous with the third side portion 23, the box bar 54 and the box 55 are arranged closer to the folded portion of the main body sheet 20A, the second tape 52A is on the side continuous with the fourth side portion 24, and the butterfly bar 56 is arranged closer to the folded portion of the main body sheet 20A.

[0035] With this configuration, at the first connecting portion 41, the butterfly bar 56 of the second tape 52A is inserted into the box 55 of the first tape 51A, and by closing the slider 53, the elements of the first tape 51A and the second tape 52A mesh with each other, and the first connecting portion 41 is connected (see FIG. 1). On the other hand, by opening the slider 53, the meshing between the elements of the first tape 51A and the second tape 52A is released, and the connection of the first connecting portion 41 is released (see FIG. 2).

[0036] As shown in FIG. 2, the second connecting portion 42 is provided in such a manner that when the main body sheet 20A is folded in half at the center so that the third side portion 23 and the fourth side portion 24 face each other, the second tape 52B is on the side continuous with the third side portion 23, the butterfly bar 56 is disposed closer to the folded portion of the main body sheet 20A, the first tape 51B is on the side continuous with the fourth side portion 24, and the box bar 54 and the box 55 are disposed closer to the folded portion of the main body sheet 20A.

[0037] With this configuration, at the second connecting portion 42, the butterfly bar 56 of the second tape 52B is inserted into the box 55 of the first tape 51B, and by closing the slider 53, the elements of the first tape 51B and the second tape 52B mesh with each other, and the second connecting portion 42 is connected. On the other hand, by opening the slider 53, the meshing between the elements of the first tape 51B and the second tape 52B is released, and the connection of the second connecting portion 42 is released (see FIG. 2).

[0038] Note that the first tape 51A and the second tape 52B can be connected to each other, and the second tape 52A and the first tape 51B can be connected to each other. As a result, the first side portion 21 and the second side portion 22 can also be closed as follows.

[0039] When the main body sheet 20A is folded in half at the center such that the first side portion 21 and the second side portion 22 face each other, the butterfly bar 56 of the second tape 52B of the second connecting portion 42 is inserted into the box 55 of the first tape 51A of the first connecting portion 41, and by closing the slider 53 provided on the first tape 51A, the elements of the first tape 51A and the second tape 52B mesh with each other.

[0040] On the other hand, the butterfly bar 56 of the second tape 52A of the first connecting portion 41 is inserted into the box 55 of the first tape 51B of the second connecting portion 42, and by closing the slider 53 provided on the first tape 51B, the elements of the first tape 51B and the second tape 52A mesh with each other. Thereby, the first connecting portion 41 and the second connecting portion 42 are connected (see Fig. 4). Note that by opening the two sliders 53 respectively, the connection between the first connecting portion 41 and the second connecting portion 42 is released (see Fig. 2).

[0041] As shown in Fig. 2, when the main body sheet 20A is folded in half at the center such that the first side portion 21 and the second side portion 22 face each other, the third connecting portion 43 is provided in such a manner that the second tape 52C is on the side continuous with the first side portion 21 and the butterfly bar 56 is arranged closer to the corner continuous with the first side portion 21, and the first tape 51C is on the side continuous with the second side portion 22 and the box bar 54 and the box 55 are arranged closer to the corner continuous with the second side portion 22.

[0042] With this configuration, in the third connecting portion 43, by inserting the butterfly bar 56 of the second tape 52C into the box 55 of the first tape 51C and closing the slider 53, the elements of the first tape 51C and the second tape 52C mesh with each other, and the third connecting portion 43 is connected (see Fig. 4). On the other hand, by opening the slider 53, the meshing between the elements of the first tape 51C and the second tape 52C is eliminated, and the connection of the third connecting portion 43 is released (see Fig. 2).

[0043] As described above, as a specific mode in which the first side portion 21, the second side portion 22, and the third side portion 23 can be easily closed or opened, the above-described configuration can be adopted.

[0044] According to this configuration, the bag 10 of the first form (see Fig. 1) in which the main body sheet 20A is folded in half at the center so that the third side portion 23 and the fourth side portion 24 face each other, and the bag 10 of the second form (see Fig. 4) in which the main body sheet 20A is folded in half at the center so that the first side portion 21 and the second side portion 22 face each other, for the bag 10 in the second form with respect to the bag 10 in the first form, since only the folding method of the same main body sheet 20A is different, the capacity of the storage area remains the same, and since the main body sheet 20A is rectangular with a long side and a short side, its shape can be made different. That is, the shape of the storage area can be changed while keeping the capacity of the storage area unchanged.

[0045] As shown in Fig. 2, by spreading the main body sheet 20A without closing the first side portion 21, the second side portion 22, and the third side portion 23, it can be used as a mat such as a leisure sheet.

[0046] The handles 30 (30A, 30B) are provided so as to extend outward from each of the third side portion 23 and the fourth side portion 24 on the outer surface of the main body sheet 20A. At that time, the handles 30 (30A, 30B) are provided with tape adjusters 36 (buckles with adjustable belt lengths) and are configured to be length-adjustable. The handles 30 (30A, 30B) are composed of a dense woven fabric imitating nylon (2.5 cm wide, maximum 50 cm long). Note that the handles 30 (30A, 30B) may be composed of other widths, lengths, and materials.

[0047] Also, among the handles 30 (30A, 30B), the handle 30A on the side extending outward from the fourth side portion 24 of the main body sheet 20A is provided with a hook 31A and is configured to be engageable with a loop 31B provided on the surface of the main body sheet 20A. Thereby, as will be described later, when it is the bag 10 of the second form (see Fig. 4) in which the main body sheet 20A is folded in half at the center so that the first side portion 21 and the second side portion 22 face each other, the unnecessary handle 30A can be fixed.

[0048] Also, as shown in Fig. 2, the sheet forming the pocket 33 forms a flap 35 (see Fig. 2) on the side opposite to the part forming the opening 34. Engaging fasteners 32 (32A, 32B) are provided on the front surface of the pocket 33 and the back surface of the flap 35 so as to be engageable with each other.

[0049] As described above, since the back surface of the main body sheet 20A is made of a waterproof material, it is possible to realize the bag 10 that can accommodate wet items in the accommodation area or items that are not desired to be wet in the accommodation area. Further, when used as a mat such as a leisure sheet, it is possible to prevent moisture on the ground where the mat is laid from being transmitted from one surface of the main body sheet 20A to the other surface.

[0050] As shown in Fig. 5, from the form of the bag 10 shown in Fig. 1, that is, the state where the main body sheet is folded in half at the center so that the third side portion 23 and the fourth side portion 24 of the main body sheet face each other on the front surface, further, at a position corresponding to the periphery of the pocket 33 on the back surface of the surface where the pocket 33 is provided, the first side portion 21 and the second side portion 22, and the third side portion 23 and the fourth side portion 24 are folded, and the flap 35 and the pocket 33 are fixed with the fasteners 32A and 32B, thereby making it compact. At that time, by storing the handle 30A in the pocket 33, the handle 30A does not get in the way when made compact.

[0051] In the above-described embodiment, the dimension ratio of the long side to the short side of the main body sheet 20A was about 1.7:1, but it is not limited to this. The dimension ratio of the long side to the short side of the main body sheet 20A may be, for example, about 1.1:1 or about 2:1.

[0052] In the above-described embodiment, the main body sheet 20A was composed of a material having waterproof property at least on the front surface or the back surface, but it is not limited to this. For example, the main body sheet 20A may be composed of hemp, cotton, or the like. The same applies to the handles 30 (30A, 30B).

[0053] Furthermore, the handle 30 (30A, 30B) may be provided at a location other than the one described above, or the handle 30 itself may not be provided.

[0054] In the above-described embodiment, the case where the first connecting portion 41, the second connecting portion 42, and the third connecting portion 43 are each constituted by a wire fastener has been described. However, the first connecting portion 41, the second connecting portion 42, and the third connecting portion 43 can also be constituted by a dot fastener or a surface fastener. It is preferable that the connection and disconnection of the first connecting portion 41, the second connecting portion 42, and the third connecting portion 43 can be easily performed.

[0055] The configurations disclosed in any of the above-described embodiments can be applied in combination with the configurations disclosed in other embodiments as long as no contradiction occurs. Also, the embodiments disclosed in this specification are examples, and the embodiments of the present invention are not limited to these, and can be appropriately modified within the scope not departing from the object of the present invention.
