Description

Technical Field

[0001] The present invention relates to container-packaged plastic waste Equal, a method for compression and encapsulation of highly compressible and resilient waste, and a compression and encapsulation waste box and is related to

Background Art

[0002] Among industrial waste, waste with high compressibility and resilience is bulky for its weight at the stage of being packed in garbage bags, resulting in high transportation and treatment costs, and also an increase in storage space.

[0003] Container packaging plastic waste discharged from households is also bulky for its weight and fills up quickly in a short period, leading to an increase in the frequency of garbage bag replacement and high garbage bag costs.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In view of the above problems Briefly, it is to provide a garbage compression and encapsulation method that can encapsulate highly compressible and resilient waste while maintaining the compressed state and can take it out of the garbage box. A garbage box that holds the opening edge of the garbage bag at the upper part of the garbage box may apply a tensile force to the garbage bag when pushing in the garbage, and the garbage bag may shift and come off. This invention solves this problem.

[0006] A garbage box that guides the opening edge of the garbage bag from the inside of a constriction cylinder protruding from the upper part of the garbage box and holds it by a folded-back holding band on the outside. The opening area of the garbage bag is made less than the horizontal projected area of the garbage, and the garbage is pushed into the opening of the garbage bag while being compressed.

Means for Solving the Problems

[0007] The method of pushing the garbage into the opening of the garbage bag while compressing the garbage can be manual, or it can also be a pushing rod or a mechanical device operated by a person.

[0008] Highly compressible and resilient waste is

[0009] Inside the garbage bag First, it is inserted while compressing from the opening of the garbage bag. Since the opening area of the garbage bag is smaller than the horizontal projected area of the garbage, even for waste with high resilience When it is full in the natural state, thereafter, by pushing it inward from the opening of the garbage bag, the entire inside of the garbage bag is compressed. Even if the hand is released The garbage inside the garbage bag it will not reverse, and the inside of the garbage bag can be kept in a compressed state.

[0010] Remove the holding band, When it reaches a considerable amount, Or seal it with a string or tape. Tie the edges of the garbage bag together, A garbage box that guides the opening edge of the garbage bag from the inside of a constriction cylinder protruding from the upper part of the garbage box and holds it by a folded-back holding band on the outside. The shape of the end of the constriction cylinder is stepped or tapered, that is, the outer peripheral length of the end of the constriction cylinder is made larger than the outer peripheral length of the part of the constriction cylinder that holds the garbage bag to prevent displacement when a tensile force is applied to the garbage bag. The garbage bag is removed from the garbage can while maintaining the compressed state.

[0011] The opening area of the garbage bag has an optimal area depending on the type and size of the garbage. It is ideal to make it slightly smaller than the horizontal projected area of the garbage from the perspective of preventing reverse return after compression and pushing.

[0012] The cross-section of the constriction cylinder

[0013] Plastic containers and packaging waste generated in homes and other places are a mixture of various sizes, but the opening area of the garbage bag is 110cm. 2 ~50cm 2 Larger trash can be manually compressed or folded and pushed in, and smaller trash can be pushed away from the opening or under larger trash to prevent backflow.

[0014] Plastic container and packaging waste for recycling is generally not very dirty, so there are no hygiene issues even if the waste is pushed in by hand.

[0015] The garbage compression and encapsulation method can simply encapsulate highly compressible and resilient waste. The shape may be circular, elliptical, rectangular, or oblong. [Effects of the Invention]

[0016] The present invention The bulk density inside the garbage bag increases and the storage capacity of the garbage increases, so the frequency of garbage bag replacement decreases, and the costs of garbage bags and garbage treatment can be reduced, and the storage space can also be made smaller. Keep it compressed and put it in a garbage bag The compression and encapsulation garbage box according to the present invention can prevent the displacement of the garbage bag even when a tensile force is applied to the garbage bag when pushing in the garbage. It can be easily removed from the trash can.

Embodiments for Carrying Out the Invention

[0020] Regarding the present invention Garbage Compression and Enclosure Method and Compression-Enclosed Garbage Bin An example of will be described in detail below with reference to the drawings in detail.

[0021] Figure 1 incorporates the garbage compression and enclosure method according to an embodiment of the present invention. In the first stage, the garbage is lightly compressed by hand and put into the garbage bag through the opening 22. When the garbage bag 20 is full of garbage in its natural state, hereafter, the garbage is lightly compressed by hand and pushed to a position beyond the opening 22 of the garbage bag, then the garbage is released and the hand is withdrawn.

[0022] When the garbage in the garbage bag 20 reaches a considerable amount, Remove the holding band 35 remove it, and gather the garbage bag opening edge 21 and then Remove the cylinder support plate 34 with the squeezing cylinder 33 attached from the upper side next, take out the entire garbage bag 20 from the garbage box body 10.

[0023] Figure 2 is Of the squeezing cylinder 33 A cross-sectional view showing the shape. The stepped squeezing cylinder 331 and the tapered squeezing cylinder 332 can prevent displacement even when a tensile force is applied to the garbage bag.

Examples

[0025] The garbage bag is a commercially available 30-liter envelope shape, the garbage box body is a rectangular parallelepiped shape, and the dimensions of the part where the garbage bag can be inserted are 315 mm in length, 240 mm in width, and 415 mm in depth. The cylinder support plate with the squeezing cylinder is separated from the garbage bin body, and the cross-sectional shape of the squeezing cylinder is circular The inner diameter is 102 mm, the outer diameter is 108 mm, the length is 25 mm, and the opening area of the squeezing part is 82 cm 2It was. The opening edge of the garbage bag was led from below to above the constriction cylinder, folded back outward at the end of the constriction cylinder, and held with a rubber band outside the constriction cylinder. The garbage put in was various container-packaged plastic garbage generated at home. With a horizontal projected area larger than the area of the opening of the garbage bag The garbage was compressed or folded by hand and pushed in. Small garbage was pushed in at a position away from the opening of the garbage bag or under large garbage. When the amount of garbage in the garbage bag reached a considerable amount, the Rubber band that held the garbage bag was removed, the periphery of the garbage bag was gathered, and it was taken out of the garbage bin while maintaining the compressed state. The test was repeated several times, and the weight of the garbage was 7.19 N on average. Incidentally, the weight when it naturally became full without compression was about 2.85 N, and an effect about 2.5 times was recognized.
