Summary of the Invention
Problems to be Solved by the Invention
[0004] The futon storage bag of Patent Document 1 is provided with a tongue-shaped member 4 for preventing the futons, which are stored items, from being caught by the fastener when the futons are stored. By arranging the tongue-shaped member 4 between the fastener 3 and the futons, it prevents the futons from being caught by the fastener 3. However, the tongue-shaped member 4 in Patent Document 1 is expanded to the outside of the storage portion. Therefore, there may be a case where the function of preventing the futons from being caught cannot be obtained when the tongue-shaped member 4 is in the state of being expanded to the outside, and there may also be a case where the tongue-shaped member 4 itself is caught by the fastener 3.
[0005] In view of the above points, the present invention relates to a storage bag for storing stored items, and an object thereof is to provide a storage bag capable of more effectively reducing the situation where the stored items are caught by the opening / closing member (such as a fastener) of the storage bag.

[0013] The embodiments of the present invention will be described in detail below with reference to the drawings. Note that the following embodiments are merely examples of how the present invention can be implemented, and do not limit the present invention to their scope.
[0014] Figure 1 is a perspective view of the storage bag 1 of this embodiment, where Figure 1(a) is a perspective view with the lid closed (and in an uncompressed state), and Figure 1(b) is a perspective view with the lid open (and in a compressed state). Figure 2 is a plan view of the storage bag 1, where Figure 2(a) is a front view with the lid closed, and Figure 2(b) is a front view with the lid open. Also, Figure 3(a) is a rear view with the lid closed, and Figure 3(b) is a side view illustrating the uncompressed and compressed states of the storage bag 1. The storage bag 1 of this embodiment is a storage bag for storing items such as clothing, and can of course be used on its own, but is primarily a storage bag used inside a suitcase or the like (for dividing luggage into smaller portions). The storage bag 1 of this embodiment is A storage compartment 11 having an opening 111, A lid member 12 that opens and closes the opening 111, A fastener (opening / closing member) 13 is provided around the opening 111 to engage / disengage the storage section 11 and the lid member 12, The device includes an anti-pinch member 15 that extends from the periphery of the opening 111 toward the center and covers the opening 111 in a non-closing manner. Hereinafter, the front side in FIG. 1(a) is referred to as the "front", the back side as the "back", and the direction from the front to the back as the "thickness direction". Also, the vertical direction in FIG. 1(a) is referred to as the "vertical direction", and the horizontal direction in FIG. 1(a) is referred to as the "horizontal direction".
[0015] The storage bag 1 of this embodiment has storage parts on both the front side and the back side (it has a partition in the center of the thickness direction and has storage parts on both sides thereof), and has lid members for opening and closing the respective storage parts on the front side and the back side. That is, it has a storage part 11 on the front side and a storage part 11' on the back side, and has a lid member 12 on the front side and a lid member 12' on the back side for opening and closing them respectively, and has a fastener 13 for engaging / disengaging the storage part 11 on the front side and the lid member 12, and a fastener 13' for engaging / disengaging the storage part 11' on the back side and the lid member 12'. The front side configuration and the back side configuration are basically symmetrical. Hereinafter, the front side configuration will be described, and the description of the back side will be omitted. Further, the storage bag 1 of this embodiment is a storage bag that can expand / contract the dimension in the thickness direction (that is, expand / contract the volume of the bag) by including a compression fastener 14 (see FIG. 3(b)). The side surfaces in the thickness direction of the storage part 11 and the storage part 11' have a double side surface including a wide first side surface used during expansion and a second side surface having the compression fastener 14. When the compression fastener 14 is open, the wider first side surface becomes the side surface in the thickness direction, so the volume is in a large state. On the other hand, when the compression fastener 14 is closed, the second side surface narrower than the first side surface becomes the side surface in the thickness direction (or there is a state where there is no substantial side surface), so the volume of the storage part is reduced. Thus, it is a storage bag that can easily compress luggage such as clothes.
[0016] The storage part 11 having an opening 111 is sewn from a flexible fabric without stretchability into a substantially rectangular parallelepiped (a container-like shape with one of the six faces constituting the rectangular parallelepiped missing). The opening 111 is formed by one of the six faces constituting the substantially rectangular parallelepiped being missing. Therefore, it has a substantially rectangular shape. As mentioned above, the storage bag 1 of this embodiment is a compressible storage bag, and therefore uses a non-stretchable fabric (because if the fabric stretches, the compression effect cannot be obtained). However, if it is not a compression bag, the storage section may be made of a material that is somewhat stretchable. Also, the shape of the storage section is not limited to a rectangular parallelepiped, but may be any shape (as long as it functions as a storage section and has an opening). Furthermore, in this embodiment, the shape of the opening is given as an example to be approximately rectangular, but the shape of the opening may also be any shape.
[0017] The lid member 12 that opens and closes the opening 111 of the storage section 11 is made of the same fabric as the storage section 11, and one vertical side is sewn to the storage section 11 so that it can be opened and closed as shown in Figures 2(a) and (b). In the storage bag 1 of this embodiment, a storage pocket 121 is provided on the front lid member 12 (see Figure 2(a)), and a handle 122 is provided on the back lid member 12' (see Figure 3(a)). In this embodiment, the lid is made of the same material as the storage compartment and has a roughly rectangular shape, but the lid may be made of a different material than the storage compartment. If it is not a compression bag, it may be made of a material that is somewhat elastic. Furthermore, its shape may be any shape that matches the shape of the opening.
[0018] The zipper 13 is provided around the opening 111, on the side other than the side where the lid member 12 and the storage section 11 are sewn together (i.e., it is provided in a roughly U-shape), and engages / disengages the storage section 11 and the lid member 12. Furthermore, the zipper is not limited to those arranged in a roughly U-shape; it is acceptable as long as it is provided in a way that allows the opening to be closed in all areas except where the lid and storage compartment are sewn together, depending on the shape of the opening.
[0019] In this embodiment, the pinch prevention member 15 is made of a stretchable fabric and, as shown in Figure 2(b), extends from three sides of the periphery of the opening 111 toward the center, covering the opening 111 in a non-closing manner. The "three sides of the periphery" are the sides on which the zipper 13 is provided, and therefore, the "pinch prevention member is provided continuously along the range in which the opening and closing member is provided." "Covering the opening in a non-closing manner" means covering the periphery of the opening while leaving the central area open.
[0020] As shown in Figure 2(b), an inner shrinkage member 16 made of an elastic material is provided on the inner circumference of the pinch prevention member 15 (in this embodiment, the inner shrinkage member 16 made of rubber is sewn to the inner circumference of the pinch prevention member 15). The inner contraction member 16 acts to contract the inner circumference of the pinch prevention member 15, thereby maintaining the state in which the pinch prevention member 15 extends from the periphery of the opening 111 toward the center. In other words, the inner contraction member 16 functions as a "holding structure that maintains the state in which the pinch prevention member extends from the periphery of the opening toward the center." To put it another way, "the holding structure is composed of an expandable and contractible member provided on the inner circumference of the pinch prevention member." Furthermore, as shown in Figure 4, in this embodiment, the pinch prevention member 15 has a length in the portion 151 (shown by a dashed line in Figure 4) that is fixed to the periphery of the opening 111, which is longer than the length of the portion 152 (shown by a dashed line in Figure 3) that is not fixed. This configuration has the effect of maintaining the state in which the pinch prevention member 15 extends from the periphery of the opening 111 toward the center. In other words, it can be said that the "length of the portion of the pinch prevention member that is fixed to the periphery of the opening is longer than the length of the portion that is not fixed" constitutes a "holding structure that maintains the state in which the pinch prevention member extends from the periphery of the opening toward the center".
[0021] According to the storage bag 1 of this embodiment having the above configuration, the anti-pinch member 15 is provided which "extends from the periphery of the opening 111 toward the center and covers the opening 111 in a non-closing manner, and has a holding structure that maintains the state in which the anti-pinch member 15 extends from the periphery of the opening 111 toward the center," thereby reducing the likelihood of stored items such as clothing stored in the storage compartment 11 getting caught in the zipper 13. Furthermore, because the anti-pinch member 15 has the above configuration, it is less likely to curl up, thus reducing the likelihood of the anti-pinch member 15 itself getting caught in the zipper 13. In addition, the anti-pinch member 15 (and the inner contraction member 16) are elastic, which makes it easy to store and retrieve items from the storage compartment 11. Conventionally, when storing a large amount of clothing or other items, it was common for the zipper to catch the stored items when closing the lid. However, with the storage bag 1 of this embodiment, the above configuration allows the zipper 13 to be closed easily even when a large amount of items are packed inside, making it extremely useful.
[0022] In this embodiment, the anti-pinch member is provided continuously along the area where the fastener (opening / closing member) is installed, but the present invention is not limited to this. For example, as shown in the schematic diagram in Figure 5(a), the anti-pinch members may be provided only on the horizontal edges (anti-pinch members 15-11, anti-pinch members 15-12), or only on the vertical edges. Alternatively, as shown in the schematic diagram in Figure 5(b), anti-pinch members 15-21, 15-22, 15-23, and 15-24 may be provided at the corners of the opening 111. As in these examples, by providing anti-pinch members at arbitrary locations within the area where the zipper (opening / closing member) is provided, the zipper can be reduced in those areas. However, as in this embodiment, providing anti-pinch members to cover the entire area where the zipper (opening / closing member) is provided is more preferable as it can more effectively prevent the zipper from getting caught. Furthermore, as shown in the schematic diagram in Figure 5(c), the pinch prevention member 15-3 may be provided around the entire circumference of the opening 111, or the pinch prevention member may be provided beyond the area where the fastener (opening / closing member) is provided.
[0023] In this embodiment, the anti-pinch member is provided continuously along the area where the fastener (opening / closing member) is provided, but the present invention is not limited to this. For example, as shown in the schematic diagram in Figure 5(d), the pinch prevention member may be composed of multiple pinch prevention members 15-41, 15-42, and 15-43, and an inner contraction member 16-2 made of an elastic material may be provided to connect these pinch prevention members to each other. In this configuration, the pinch prevention member may be made of a material that does not stretch (for example, a resin plate, etc.), and because each pinch prevention member 15-41, 15-42, and 15-43 is divided, it is possible to widen the opening portion of the opening 111 by opening each pinch prevention member, which provides excellent workability for storing and retrieving items from the storage section 11. Furthermore, if the pinch prevention member is provided in separate parts, some pinch prevention members will be prone to curling up. However, by connecting each pinch prevention member with the inner contraction member 16-2, it is possible to "maintain a state in which the pinch prevention member extends from the periphery of the opening toward the center." Figures 6(a) and 6(b) show yet another example of using multiple anti-pinch members. In Figure 6(a), the anti-pinch member, which is divided into three parts in Figure 5(d), is divided into two parts to form two L-shaped anti-pinch members 15-51 and anti-pinch member 15-52. In Figure 6(b), the anti-pinch member provided all around in Figure 5(c) is divided into two parts to form two U-shaped anti-pinch members 15-61 and anti-pinch member 15-62.
[0024] In this embodiment, the anti-pinch member 15 is made of an elastic material (which eliminates the need to provide gathers (pleats)). However, the present invention is not limited to this. For example, by sewing an anti-pinch member with an excess length to the inner shrinkage member 16 so that the anti-pinch member has gathers, the anti-pinch member can be made to have a stretchable function even if the fabric itself is not stretchable, and the workability of storing and retrieving items from the storage section 11 can be improved (although not specifically shown in the illustration, gathers (pleats) are formed, resulting in an anti-pinch member with a wrinkled appearance). Furthermore, it is preferable to give the anti-pinch member an elastic function by making it from an elastic material or by sewing it to have gathers as described above, but the anti-pinch member may not be elastic (i.e., the anti-pinch member can be made from any material, such as resin). As mentioned above, the anti-pinch member covers the opening in a non-closing manner, and the area near the center of the opening is open, so it is possible to put in and take out flexible stored items such as clothing or stored items that are large enough to pass through the open part of the opening. Furthermore, at least a portion of the pinch prevention member may be made of an elastic material. For example, the pinch prevention member 15-41 shown in Figure 5(d) may be made of an elastic material, and the pinch prevention members 15-42 and 15-43 may be made of non-elastic materials, and these may be sewn together to form an overall "pinch prevention member in which at least a portion is made of an elastic material." In contrast to the "connection of each divided pinch prevention member with an inner contraction member 16-2 made of a connecting elastic material" as explained in Figure 5(d), by making one of the divided pinch prevention members of an elastic material instead of the inner contraction member 16-2 and connecting each pinch prevention member to each other, it is possible to have the function of widening the opening portion without using the inner contraction member 16-2.
[0025] In this embodiment, a storage bag is provided with a compression fastener 14, which allows the storage compartment to be reduced in volume (compressed). However, the present invention is not limited to this, and the concept of the pinch prevention member of the present invention, as understood from the above description, can of course be applied to storage bags that do not have a compression fastener. Furthermore, although this embodiment uses a flexible storage bag made of fabric as an example, the present invention is not limited to this, and the concept of the pinch prevention member of the present invention as understood from the above description can also be applied to storage cases made of "hard" materials such as hard-type suitcases or clothing cases (the term "storage bag" in this invention is a concept that includes storage cases, etc.).
