Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage reduction bag used for reducing the volume of garbage when discarding the garbage.

[0002]

2. Description of the Related Art There is a very large amount of garbage depending on its kind. For example, garbage discharged from fast food stores, such as containers for drinks and cases for food, are spaces inside, are light but very bulky, and have the same weight as ordinary garbage. It took three to four times as many garbage bags to throw away the garbage. The number of garbage bags that can be carried at one time varies depending on the individual, but is usually about 2 to 4 garbage bags. For this reason, if the number of garbage bags is increased three to four times, three to four times as many people are required to transport the garbage to the collection place. 〜4 times more labor was required. In addition, when transporting garbage from a collection place to an incineration plant or a clean center, etc., the bulky garbage causes poor transport efficiency and increases costs.

[0003] When the garbage is further bulky, a large area is required for a place for temporarily storing the garbage and a place for collecting the garbage until the garbage is brought to the collection place. This led to an increase in total cost. For this reason, a method for reducing the volume of bulky dust is required, but a method for reducing the volume extremely simply without requiring a special device has not yet been provided.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a bag for easily reducing the volume of dust.

[0005]

According to the present invention, as a means for solving the above-mentioned problems, a bottom seal 4 is provided at one opening of a tube 2 made of a thermoplastic resin, and the other opening is provided with dust. A partition seal 5 is provided from the one side 8 to the other side 9 of the tube 2 on the side of the bottom seal 4 on the dust inlet 3 side, leaving a non-sealed portion 6. Further, there is provided a garbage reduction bag characterized in that a deaeration hole 7 is provided between the bottom seal 4 and the partition seal 5.

That is, when dust is directly put into a normal dust bag, gas is not discharged, so it is difficult to reduce the volume of dust after the bag is full. However, the garbage reducing bag according to the present invention has a means for discharging only gas without leaking garbage or liquid contained in the garbage. The volume of the refuse can be reduced only by closing the inlet and pressurizing. Further, if necessary, by reducing the volume of the garbage and then charging the garbage bags together with the reduced volume bags, a large amount of garbage can be charged into one garbage bag, and the above problem can be solved.

The bag for reducing garbage of the present invention has means for discharging only gas without leaking garbage or liquid contained in the garbage. This means will be described with reference to FIG. FIG. 1 is a perspective view showing an embodiment of a garbage reduction bag according to the present invention. The garbage reduction bag of the present invention does not leak the refuse, and does not leak the liquid even if the refuse contains a liquid. This is because ordinary dust stops at the partition seal 5, and the liquid passes through the partition seal 5 to reach the unsealed portion 6, further flows from the unsealed portion 6 toward the bottom of the bag, and accumulates near the bottom seal 4. .

Further, when the garbage reducing bag 1 is full of garbage, the garbage inlet 3 is closed and pressurized to reduce the volume of garbage. At this time, the gas in the bag is not sealed. 6 and is discharged from the deaeration hole 7 to the outside of the bag. When the normal bag is provided with the deaeration hole 7, the bag can be deaerated by pressurizing the bag, but when the pressurization is released, outside air flows again into the bag from the deaeration hole 7. However, in the garbage reducing bag according to the present invention, when the bag is pressurized and evacuated, the space between the bottom seal 4 and the partition seal 5 adheres due to the difference between the internal pressure and the atmospheric pressure. Intrusion is prevented,
The volume reduction state can be maintained for a long time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a garbage reduction bag according to the present invention. The resin composition of the garbage reducing bag 1 is not particularly limited. For example, polyethylene such as linear low-density polyethylene, low-density polyethylene, high-density polyethylene, ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, etc. Resin, polypropylene resin,
Nylon resin, polystyrene resin, polyethylene terephthalate resin, and other similar resins that have been conventionally processed into plastic bags can be used, but in consideration of economics and strength, it is particularly preferable to use low-density polyethylene resin. preferable.

The garbage reducing bag 1 according to the present invention is formed by molding a single-layer tube 2 by using one of the above-mentioned thermoplastic resins and their blends, or by forming a multilayer by using two or more of them. Is obtained by forming a bottom seal 4, a partition seal 5, and a deaeration hole 7 in the tube 2. The method for forming the tube 2 is not particularly limited. For example, the above-described thermoplastic resin is formed into a film by a T-die extrusion method or the like, and the obtained film is folded back. It is advisable to cut it at regular intervals. In addition, according to the inflation extrusion molding method, the thermoplastic resin described above can be extruded into a cylindrical thin film, so that the tube 2 can be obtained only by cutting the same at predetermined lengths.

Next, regarding the bottom seal 4, the sealing method is not particularly limited. For example, heat sealing may be performed using a seal bar in the same manner as a general bottom seal of a polyolefin resin bag. Also, the position and shape of the bottom seal 4 are not particularly limited, and may be provided linearly near one opening, for example, like a general-purpose bag.

On the other hand, regarding the partition seal 5, the sealing method is not particularly limited, and for example, heat sealing may be performed using a seal bar as in the case of the bottom seal 4. The shape of the partition seal 5 is not particularly limited as long as the shape extends from one side 8 of the tube 2 to the other side 9 of the tube 2 except for the unsealed portion 6, and for example, as shown in FIG. 5 has a slight unsealed portion 6 between one end and the side 8, and further has some unsealed portion 6 between the other end of the partition seal 5 and the side 9. good. At this time, the unsealed portion 6
Preferably has a width that allows gas or liquid to pass therethrough without passing through the garbage as contents, and specifically, preferably has a width of about 2 to 80 mm.

Further, the position of the partition seal 5 is not particularly limited as long as it is located closer to the dust inlet 3 than the bottom seal 4 and the distance α from the bottom seal 4 is larger than the diameter β of the deaeration hole 7. However, preferably, the distance α from the bottom seal is 10 to 1
It is preferably about 50 mm. If the distance between the bottom seal 4 and the partition seal 5 exceeds 150 mm, not only does the capacity of the volume reduction bag decrease, but also it becomes difficult for the bottom seal 4 and the partition seal 5 to adhere to each other after the inside of the bag is evacuated. Is difficult to prevent from re-entering the bag. Further, the interval α between the bottom seal 4 and the partition seal 5 must be at least larger than the diameter β of the deaeration hole 7, and it is particularly preferable that the distance α is larger than β by 5 mm or more. This is because if the dust contains liquid, the liquid accumulates in the vicinity of the bottom seal 4. If the diameter β of the deaeration hole 7 is substantially equal to the interval α, the deaeration hole 7 There is a possibility that the liquid reaches a very close position and the liquid leaks out from the deaeration hole 7. Therefore, it is preferable that the deaeration hole 7 is separated from the bottom seal 4 by at least 5 mm or more. In addition, in order to discharge gas smoothly, the deaeration hole 7
Preferably, the diameter β exceeds 2 mm, and therefore, the distance α between the bottom seal 4 and the partition seal 5 preferably exceeds 7 mm.

Next, the shape of the deaeration hole 7 is not particularly limited, and a desired shape such as a round shape, a square shape, and a triangular shape can be obtained. Also, the number of the deaeration holes 7 is not particularly limited, but it is difficult to provide the deaeration holes 7 on only one surface of the tube 2. Therefore, it is preferable that the deaeration holes 7 be provided on the front and back surfaces of the tube 2. Even if it is too long, it only takes time to process and does not improve the deaeration speed. In consideration of these facts, it is preferable to provide two or four deaeration holes 7, but the present invention is not limited to this. The size of the deaeration hole 7 is not particularly limited. However, if the size is too small, deaeration cannot be performed smoothly. If the size is too large, the deaeration speed is not improved, and the volume of the garbage reduction bag 1 is reduced. May lead to In consideration of these, it is preferable that the diameter of the deaeration hole 7 is about 2 to 50 mm.

FIGS. 2A and 2B are perspective views showing another embodiment of the garbage reducing bag of the present invention. Partition seal 5
May be a curve as shown in FIG. At this time, if the partition seal 5 has a chevron shape protruding toward the dust inlet 3, when the gas in the volume reduction bag is discharged, the gas between the partition seal 5 and the dust inlet 3 becomes It flows smoothly to the bottom seal 4 side.

The partition seal 5 may have an unsealed portion 6 in the partition seal 5, as shown in FIG. 2B. At this time, the unsealed portion 6 is not positioned immediately above the deaeration hole 7. If liquid is mixed in the garbage,
The liquid flows downward, passes through the partition seal 5, is guided to the unsealed portion 6, flows from the unsealed portion 6 to the bottom side, and accumulates near the bottom seal 4.
If the liquid is located right above the liquid, it may reach the deaeration hole 7 while flowing from the unsealed portion 6 to the vicinity of the bottom seal 4 and leak out of the bag from the deaeration hole 7.

FIGS. 3A and 3B are perspective views showing another embodiment of the garbage reducing bag 1 according to the present invention, in which a partition seal 5 is provided double. FIG. 3A shows that the partition seal 5 on the dust inlet 3 side has an unsealed portion 6 at the center of the seal and the partition seal 5 on the bottom seal 4 side intersects both sides 8 and 9 of the bag. This is a garbage reduction bag having an unsealed portion 6. The gas passage in the bag when the bag is pressurized and reduced in volume is indicated by an arrow in the figure. 3 (B), the partition seal 5 on the dust inlet 3 side has an unsealed portion 6 at the intersection with the side 9 and the partition seal 5 on the bottom seal 4 is on the side of the bag. This is a garbage reduction bag having an unsealed portion 6 at a portion intersecting with the side 9. The gas passage in the bag when the bag is pressurized and reduced in volume is indicated by an arrow in the figure. In any case, it takes longer to deaerate than when only one partition seal 5 is used, but it is possible to more reliably prevent the gas from re-introducing after the deaeration.

Next, a waste disposal method using the waste volume reduction bag 1 according to the present invention will be described with reference to FIG. First,
The garbage 10 is introduced from the garbage inlet 3 into the garbage reducing bag 1 (A). For example, when the garbage reducing bag 1 according to the present invention is used in a fast food store or the like, the garbage reducing bag 1 may be set in a trash box in advance. At this time, if the dust contains the liquid 11, the liquid 11 accumulates near the bottom seal 4.

When the volume reducing bag 1 is full with the garbage 10, the garbage inlet 3 is closed (B). At this time, when the bag is pressurized in a post-process, the dust inlet 3 is securely closed so that the dust inlet 3 does not open due to the weight of the dust or the dust leaks from the gap between the dust inlets 3. Keep it. Examples of such a closing means include a method of twisting the dust input port 3 and then tying it, and a method of heat sealing and closing.

When the dust inlet 3 can be closed, the bag is pressurized to reduce the volume of dust (C). At this time, if the garbage bag is pressed as it is, there is a possibility that the liquid accumulated near the bottom seal 4 may leak out of the deaeration hole 7. Therefore, it is preferable to turn the bag upside down before pressurizing. The pressing method is not particularly limited, and examples thereof include a method of pressing with hands or feet, a method using a press machine, and the like.

In order to reliably maintain the reduced volume state for a long time, it is desirable to put the reduced volume garbage reduction bag 1 into the garbage bag 12 and discard it. The bag 1 is put into one trash bag 12 (D). The rate of reduction of the volume of dust differs depending on the pressing method. However, when a pressing machine is used, dust is usually 1/3 to 1 /
Since the size of the garbage bag 12 is approximately the same as that of the garbage reducing bag 1, one garbage bag 1
2 can load 3 to 4 garbage reduction bags.

[0022]

According to the present invention, the bulk of garbage that is bulky for its weight, such as garbage discharged at a fast food restaurant,
It can be reduced very easily. Then, if you put the garbage in the garbage reduction bag, compress it, and then put it in the garbage bag and discard it, you can put more garbage in one garbage bag than before, and move the garbage bag to the garbage collection point. It is possible to reduce the trouble of bringing the garbage and the work of the garbage collector to put the garbage into the collection vehicle, and further reduce the number of storage places for the garbage in the store. Further, the waste volume reduction bag of the present invention does not leak liquid even if the liquid is mixed in the waste.
