Net collection bags for net stands

Abstract

To provide a net collection bag for a net stand, which can reduce the amount of work and time involved in sewing and thereby reduce costs compared to conventional methods. [Solution] In the collection bag 10 of the present invention, the rectangular first side member 11 and second side member 12, and the bottom member 13 connecting the bottom edges of the first and second side members are formed from a single sheet of net material, and both side edges of the first side member and both side edges of the second side member are sewn together to form the sides (11, 12) of the collection bag that surround a storage space 20 with an open top. When the collection bag is not in use, the bottom member 13 is folded in a mountain fold and stored between the first side member 11 and the second side member 12, which are arranged close to each other. When the collection bag is in use, the first and second side members are spaced apart and the bottom member 13 unfolds from the mountain fold into a generally flat shape, expanding the base area of ​​the collection bag.

Description

[Technical Field]

[0001] This invention relates to materials for the collection and temporary storage of household waste and other waste, and in particular to a net collection bag used as an inner bag attached to the inside of a net stand (a support material for the inner bag). [Background technology]

[0002] Net stands have been proposed as a material suitable for collecting and temporarily storing household waste, particularly PET bottles and aluminum cans (see Non-Patent Document 1). The net stand is intended to be used in conjunction with an inner bag attached to its inside, and functions as a support for the inner bag or an outer frame that helps the inner bag stand upright. For example, as shown in Figure 1, a garbage station (temporary garbage collection site) can be easily constructed by attaching a net collection bag 2, which serves as an inner bag of a roughly similar shape, to a rectangular parallelepiped net stand 1 with an open top.

[0004] The conventional net collection bag 2 used in conjunction with the net stand 1 has a rectangular parallelepiped shape as shown in FIG. 1. This rectangular parallelepiped shape is assembled, for example, using the structure and procedure shown in FIG. 2(A). Specifically, the first side 3, bottom 4, and second side 5 of the collection bag are constructed from a single sheet of net material, and the third side 6 and fourth side 7 of the net material are sewn to this single sheet, respectively, to form the rectangular parallelepiped collection bag 2 with an open top. Therefore, three sides (shown by bold lines in FIG. 2(A)) must be sewn between the single sheet (first side 3, bottom 4, and second side 5) and the third side 6. Similarly, three sides (shown by bold lines in FIG. 2(A)) must be sewn between the single sheet and the fourth side 7. Therefore, at least six sides must be sewn in total. The amount and time required for sewing contribute to high costs.

[0005] The object of this invention is to provide a net collection bag for a net stand that can reduce the amount of work and time required for sewing, thereby achieving lower costs than conventional methods. [Means for solving the problem]

[0006] [Basic idea of ​​this invention] In view of the shortcomings of the conventional example shown in Figure 2(A), the present invention has conceived of a net collection bag with the structure shown in Figure 2(B). Specifically, the first side 3, bottom 4, and second side 5 of the collection bag are constructed from a single sheet of net material, and the portion of the sheet that corresponds to the bottom 4 is folded inward in a mountain fold to bring the first side 3 and the second side 5 closer together. In this state, the left and right sides of the first and second sides 3 and 5 are sewn together (i.e., only the left and right sides are sewn) to form a collection bag with an open top.

[0007] [Specific measures] This invention is a net collection bag to be attached to the inside of a net stand, The rectangular first and second side members and the bottom member connecting the bottom sides of the first and second side members are formed from a single sheet of net material, By sewing together both side edges of the first side member and both side edges of the second side member, sides of the collection bag are formed that surround a storage space with an open top, When the collection bag is not in use, the bottom material is folded in a mountain fold and stored between the first side material and the second side material that are arranged close to each other, This is a net collection bag characterized in that, when the collection bag is in use, the first side material and the second side material are positioned at a distance from each other, and the bottom material is expanded from its mountain-folded shape to an approximately flat shape, thereby increasing the bottom area of ​​the collection bag. [Effects of the Invention]

[0008] According to this invention, the sewing points required to form the sides of the collection bag that surround the storage space with an open top are limited to both side edges (i.e., two sides) of the first and second side materials, thereby reducing the amount of work and time required for sewing and achieving lower costs than conventional methods.

DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the present invention will now be described with reference to the drawings. Figures 3 to 6 show a net collection bag 10 that is to be attached to the inside of a net stand.

[0011] 3, 5, and 6, the collection bag 10 comprises a rectangular first side member 11, an equally rectangular second side member 12, and a bottom member 13. The bottom member 13 is disposed between the two side members so as to connect the bottom edge of the first side member 11 with the bottom edge of the second side member 12. The first side member 11, second side member 12, and bottom member 13 are formed from a single sheet of net material.

[0012] As shown in FIG. 4(A), a first crease is provided along boundary line K1 at the boundary between the first side member 11 and the bottom member 13, corresponding to the bottom edge of the first side member 11. A second crease is provided along boundary line K2 at the boundary between the second side member 12 and the bottom member 13, corresponding to the bottom edge of the second side member 12. A third crease is provided along center line K3 at the center of the bottom member 13 (center line K3 is referred to as the "central crease line"). The boundary line K1, boundary line K2, and central crease line K3 are parallel to one another, and therefore the first, second, and third creases also extend parallel to one another. The presence of the three creases, including the central crease line, allows the bottom member 13 to be folded and stored when the collection bag 10 is not in use.

[0013] The net material that makes up the first and second side members 11, 12 and the bottom member 13 is made by weaving synthetic fibers vertically and horizontally to form a net or mesh, and has a certain degree of flexibility. The thickness of the synthetic fibers used is, for example, 700 to 900 deciDex, but is not limited to this range. However, the thickness of the synthetic fibers used and the coarseness of the net or mesh after weaving must not impair the flexibility of the net material.

[0014] Both side edges of the first side member 11 (left side edge 11a and right side edge 11b shown in FIG. 3) and both side edges (12a, 12b) of the second side member 12 are connected by overlapping the corresponding side edges, folding the overlapped portions back and overlapping them again, and then sewing them together in the vertical direction (height direction) (see seam line S1 and overlapping seam 14 in FIG. 4(B)). The first side member 11 and the second side member 12 connected in this way form the side surfaces of the collection bag that completely surround the storage space 20 inside the collection bag (see FIG. 6). In this way, the side surfaces (11, 12) of the collection bag that surround the storage space 20 and the bottom surface member 13 form the open-topped, bag-shaped collection bag 10.

[0015] As shown in Figures 3, 5, and 6, a string 30 is attached to the top end of the collection bag. Specifically, the top ends of the first and second side panels are folded inward by a width of several centimeters and sewn together to form a tunnel-like shape, and one string 30 is inserted through this tunnel-like part. The two ends of the string 30 are led out of the collection bag from the two open ends of the tunnel-like part, respectively, and both ends are tied outside the collection bag to form a knot. This string 30 is an operating member used to close or open the top opening of the collection bag, and the user (caretaker) of the bag can close (or tighten) the top opening of the bag by pulling the string 30.

[0016] The collection bag 10 of this embodiment can change its shape depending on whether it is in use or not.

[0017] When the collection bag 10 is not in use (for example, when stored in a storage cabinet), the first side material 11 and the second side material 12 are arranged close to each other, and the bottom material 13 is stored between these side materials in a mountain-folded state, as shown in Figures 4(A) and 5. The "mountain-folded shape" refers to an inverted V-shape in cross section as shown in Figure 4(A), which is bent with the central fold line K3 as the apex.

[0018] When the collection bag 10 is in use, the first side member 11 and the second side member 12 are spaced apart, and the bottom member 13 unfolds from the mountain-folded shape to a generally flat shape, as shown in Figure 6. The term "generally flat" does not mean a strictly flat shape in the geometric sense, but rather a relatively flat shape with a gently curved shape resembling a basin with slightly raised edges near both ends. Unfolding the bottom member 13 to a generally flat shape expands the base area of ​​the collection bag 10, thereby expanding the internal volume of the collection bag 10 and enabling the collection and temporary storage of waste.

[0019] [Effects of the embodiment] According to the collection bag 10 of this embodiment, the sewing required to form the side of the collection bag surrounding the open-top storage space 20 is only on both side edges (i.e., two sides) of the first and second side members 11, 12. Therefore, compared to conventional collection bags that require sewing on at least six sides, the amount of work and time required for sewing can be reduced, thereby reducing costs.

[0020] The collection bag 10 of this embodiment can ensure the same waste storage capacity (storage volume) and ease of attachment to a net stand as conventional collection bags. After collecting waste (e.g., PET bottles) in the collection bag 10 while it is attached to the net stand, the collection bag 10 can be removed from the net stand relatively easily, providing high convenience.
