Description

  The present invention relates to a self-supporting draining bag that is placed directly on a sink to store garbage and drain it.

At home, draining bags are used to temporarily store garbage generated in the kitchen. In that case, store the draining bag in a plastic container placed in the corner of the sink or a garbage receptacle in the drain, etc., and food waste and tea bags such as vegetable scraps, fish meal, leftover food, etc. generated after cooking and eating, Store tea leaves in the bag.
When the garbage is full, the draining bag is generally put into a large garbage bag.
However, since it is not easy to remove the draining bag from the container, there is a draining bag in which holes for passing a knot are provided at both ends of the opening, and the knot through the hole can be removed with one hand. It has been proposed (Patent Document 1).
In addition, there has been proposed a method in which the cover surface is joined to a draining bag and the garbage collected is covered by covering the garbage so that the cleanliness of the kitchen can be improved (Patent Document 2).
Furthermore, since the leftover food in the draining bag rots and leaves fly, a method of applying a repellent to the entire bag can be considered to avoid it, but the repellent is effective because the vaporized material stays Because it is limited to the space to be used, it can be expected that the fly will not enter the bag, but it will not be effective until it is driven away, so that the insecticidal component is carried on the peak of the opening end attached to the support member of the draining bag A method has been proposed (Patent Document 3).

On the other hand, the method of accommodating the draining bag in the garbage container occupies a certain space in the narrow sink, so that the sink is further narrowed. In addition, garbage containers are easily soiled and need to be cleaned from time to time. In view of this, a method has been proposed in which a food waste container is not placed in the sink, so that it can be self-supporting only with a draining bag.
For example, a draining bag (Patent Document 4) that can be self-supported by disposing an endless belt-like reinforcing sheet on the side surface of a water-permeable bag body, and a plurality of draining holes at least on both side surfaces. There is proposed a self-supporting draining bag (Patent Document 5) in which the upper part of the opened side surface is folded downward and the side surface in the vicinity of the folding line and a part of the folded side surface are cut out to form a grip portion. .

However, the above-mentioned self-supporting draining bag has a large opening at all times, so that the garbage can be seen completely, and when it is thrown away into a large garbage bag, the opening cannot be closed, so the garbage pops out. There is a fear.
In view of the above circumstances, the present invention is arranged directly on a sink or the like, and after opening the opening and storing garbage, the opening is easy to close, and when throwing away into a large garbage bag, the opening is opened. An object is to provide a self-supporting draining bag that can be closed properly.

The present invention is a self-supporting draining bag for storing garbage or the like, and draining the sheet or film. It is formed by joining, and has a rectangular bottom, an extensible side, and an openable opening.
In this way, both sides of the sheet or film are folded in an odd number and the edges are overlapped, so after opening the opening and storing the garbage, the opening starts to close naturally and sanitary And it looks good.
And the mountain fold part which opposes in a non-contact state is formed in the inside of the said rectangular body, and folds the said sheet | seat or the said film at least 3 times so that the said edge of the opposing side may overlap in each of this mountain fold part Therefore, the side portion is bellows-like and easily stretched, and even when the amount of garbage etc. increases, it can cope with it.
Here, it is preferable that the film is made of a thermoplastic resin and has pores formed in the entire rectangular body. In that case, if the split cloth is attached to a part of the film, the self-supporting property can be further enhanced.
The sheet is preferably a porous non-woven fabric or mesh fiber made of a thermoplastic resin.
Thus, since the thermoplastic resin such as polyethylene or polypropylene is used as the material, the end portions can be easily welded and joined with the heat sealer.
Further, the edges are expanded to open the opening, the side portions are extended to accommodate the garbage, and the opening is opened by pulling the joined upper and lower ends in opposite directions. Can be closed. Therefore, it is easy to store garbage, etc., it can be easily carried by grabbing the edge, and when throwing away into a large garbage bag, etc., pull the welded end to close the opening properly Can also prevent garbage from popping out.

  Whenever it is necessary to store garbage etc., the self-supporting draining bag of the present invention is arranged in the sink by extending the side part, and when the garbage etc. is collected to some extent, the whole bag is discarded into a large garbage bag etc. Because it can, it does not get in the way of cooking. In addition, since the opening is normally closed, the opening edge is expanded to store garbage, etc., but the overlapped edges are welded and joined, so the opening is closed naturally. At first, it looks good. Moreover, when throwing away into a large garbage bag etc., since an opening part can be closed properly, it can suppress that garbage etc. jump out.

Below, embodiment of the self-supporting draining bag of this invention is described.
[First Embodiment]
FIG.1 and FIG.2 is a figure which shows an example of the self-supporting draining bag of 1st Embodiment, FIG. 1 is a figure which shows a plane, FIG. 2 is a figure which shows a side surface.
As shown in FIGS. 1 and 2, the self-supporting draining bag 20 of the first embodiment has a long side and a short side, and folds both sides of the film 1 provided with a large number of pores H three times. A rectangular body is formed by overlapping the short side edges 6 and 7, and the upper end 8 and the lower end 9 of the rectangular body 5 are welded and joined. Therefore, the self-supporting draining bag 20 of the present embodiment includes a rectangular bottom portion 10, a pair of side portions 11 that extend, and an opening portion 12.
The opening 12 is normally closed because the short side edges 6 and 7 are overlapped and both ends are welded. However, since the middle of the edges 6 and 7 is not welded, the opening 12 can be opened by grasping the edges 6 and 7 with both hands and expanding them in the directions of arrows A and B. In that case, since the edges 6a, 6b, 7a, 7b and the vicinity of the edge are welded and joined, the state in which the edges 6, 7 are overlapped is maintained, and when the hand is released from the edges 6, 7 widened to the left and right, The closing force acts and closes gently.
Further, two mountain fold portions 3 and one valley fold portion 4 are formed on the outer surface side of the side portion 11, and when the bottom portion 10 is pushed in the direction of the arrow C with a hand inserted into the opening portion 12, the side portion 11 expands. In addition, a storage space such as garbage is formed inside.
When the upper end 8 and the lower end 9 which are welded and joined are pulled in a state where a certain amount of garbage is stored in the storage space, the opening 12 can be closed properly.

3 to 6 are diagrams showing a schematic process for understanding the structure of the self-supporting draining bag of the present embodiment, FIG. 3 is a diagram showing a portion where the film is folded, and FIG. FIG. 5 is a diagram illustrating a state where a valley folding and a mountain folding are performed, FIG. 5 is a diagram illustrating a rectangular body plane formed by folding all portions, and FIG. 6 is a schematic diagram illustrating an upper end or a lower end of the rectangular body. .
The film 1 shown as an example in FIG. 3 is made of a thermoplastic resin, and in order to form two opposed mountain folds 3 and four valley folds 4 facing away from each other, the points where the valleys fold are formed. This is indicated by a one-dot chain line, and a portion where the mountain is folded is indicated by a two-dot chain line. When the film 1 is folded along these chain lines, a rectangular body (shown in FIG. 5) having the central rectangular portion as the bottom 10 is formed.
Here, the film 1 shown as an example uses a high-density polyethylene extruded with a die cut at the top and bottom, and is perforated. However, the present invention is not necessarily limited to this. After folding, the hole may be punched and the top and bottom may be cut into a predetermined size, or the hole may be punched after being cut.
High-density polyethylene has strength such as being frequently used in shopping bags and garbage bags, and has the property that it can be easily welded and bonded by pressing a hot plate with the films overlaid.

In the embodiment shown in FIG. 4, the portion indicated by the alternate long and short dash line on the innermost side of the film 1 is valley-folded, and the portion indicated by the two-dot chain line located immediately outside thereof is mountain-folded. Therefore, the mountain fold portions 3 formed on both sides face each other in a non-contact state.

The mode shown in FIG. 5 shows a rectangular body 5 formed by valley-folding the part indicated by the alternate long and short dash line in FIG. As is apparent from FIG. 5, the edges 6 and 7 of the film 1 overlap each other, and each of the edges 6 and 7 also overlaps the opposing mountain fold 3 (not shown in the figure).

The mode shown in FIG. 6 schematically shows the upper end or lower end of the rectangular body 5. Since the rectangular body 5 in this embodiment is formed by folding the both sides of the film 1 three times, the mountain folds 3 are formed one by one on the left and right, and the two valleys 4 are formed on the left and right. The left and right mountain fold portions 3 face each other in a non-contact state, and the side edges 6 and 7 on both sides overlap each other and also overlap the opposite mountain fold portions 3.
Thus, when the upper end and lower end of the rectangular body 5 with the film 1 overlapped are welded and joined with a heat sealer or the like, the self-supporting draining bag 20 of the present embodiment can be obtained.
In that case, without cutting the long film extruded with a die at a predetermined size, both sides were continuously folded, a large number of pores were opened from the folded top, and welded with a sealer for each predetermined length Then, if the method of cut | disconnecting is used, the self-supporting draining bag 20 can be manufactured efficiently.
Here, the film 1 of the present embodiment is folded three times, and one mountain fold part 3 is formed on each side of the rectangular body 5. However, if the number of times of folding is an odd number, it is necessary to limit to three times. There may be five times. In this case, if the number of times of folding is N, (N−2) mountain folds 3 and (N−1) valley folds 4 are formed on both sides of the rectangular body 5.

[Second Embodiment]
The self-supporting draining bag 21 of the second embodiment is different from the self-supporting draining bag 20 of the first embodiment in that a split cloth is used for a part of the film 1.
FIG. 7 is a diagram illustrating a film with a split cloth used in the second embodiment.
The film 1 shown in FIG. 7 is made of a thermoplastic resin like the film 1 in the first embodiment. Each side of the film 1 is sequentially folded (displayed by a one-dot chain line) and mountain folded (displayed by a two-dot chain line). ), Make a valley fold (displayed with a dashed line). As a result, the central rectangular portion becomes the bottom portion 10, and the valley-folded and mountain-folded portions become the bellows-like side portions 11 that are extensible. In that case, since the split cloth is affixed to the center part which becomes the bottom part 10, it is easy to maintain the shape of the bottom part 10, and self-supporting property is further maintained.
The split cloth shown here is made, for example, by splitting a split web obtained by tearing a polyethylene film vertically and horizontally and heat-sealing the overlapping portions, but is not necessarily limited thereto.

8 and 9 are diagrams showing a self-supporting draining bag formed by a film with a split cloth, FIG. 8 is a diagram showing a plan view, and FIG. 9 is a diagram showing a side surface viewed obliquely from above.
By opening each of the edges 6 and 7 of the opening 12 in the directions of arrows A and B, an opening for storing garbage or the like is opened, and the bottom 10 visible from the opening shows a split layered vertically and horizontally. Moreover, although the space which accommodates garbage etc. expands by extending the side part 11 up and down in the arrow D direction, since the split cloth is used for the bottom part 10, sitting is good.

[Third Embodiment]
The self-supporting draining bag of the third embodiment is different from the self-supporting draining bag of the first embodiment in that a sheet 2 made of mesh-like fibers or porous nonwoven fabric is used, but otherwise Are common to each other, and a duplicate description is omitted, and only the different sheets 2 will be described.
FIG. 10 is a diagram illustrating a sheet used in the third embodiment.
As shown in FIG. 10, the sheet 2 used in this embodiment is made of a thermoplastic resin, and a non-woven fabric mainly composed of a high-density polyethylene net or a heat-bonding synthetic fiber is used. All materials are porous and easy to drain.
Each of the edges 6 and 7 of the sheet 2 is sequentially displayed as a valley fold (indicated by a one-dot chain line), a mountain fold (indicated by a two-dot chain line), and a valley fold (indicated by a one-dot chain line) in the same manner as the film 1 of the first embodiment. ), Two mountain folds 3 and one valley fold 4 are formed. As a result, the central rectangular portion becomes the bottom portion 10, and the valley-folded portion and the mountain-folded portion become the bellows-like side portion 11 that can be freely expanded.
Here, the high-density polyethylene net preferably has a size of 1 mm or less because garbage or the like flows out if the mesh size is large. Moreover, the nonwoven fabric can use heat bonding synthetic fibers, such as polyethylene, a polypropylene, polyester, those composite fibers, or the blend of these and cellulose fibers, such as rayon. However, since it is necessary to perform heat sealing, the use of a non-woven fabric in which heat-adhesive synthetic fibers and cellulose fibers are mixed is limited to those in which the mixing ratio is kept below a certain level.

  In addition to storing garbage, etc., it can be used as a general garbage bag by placing it in a familiar place or in an automobile, or as a bag for temporarily storing wet items to drain.
