Description

Detailed Description of the Invention

The present invention compresses a waste plastic container used to reduce the volume of used plastic trays, PET bottles, and other various containers that have been packed with foods and beverages. Regarding the device.

[0002]

2. Description of the Related Art Garbage discharged at home is collected by local governments such as municipalities, and the disposal method is different depending on the type of garbage due to problems such as environment and resource saving. For this reason, residents are requested to dispose of garbage, and the collection days differ depending on the type of garbage. For example, for burning garbage such as kitchen waste, paper waste, disposable diapers, wood waste, cloth waste, and rubber,
About twice a week, about non-burnable garbage such as metal, glass, pottery, etc. about once to twice a month, about empty bottles, empty cans, waste plastics such as the above, recycled garbage etc. The collection date is set to about twice, and the local residents can only dispose of the designated garbage on the decided day.

Until recently, many local governments allowed waste plastic containers to be put in the burning garbage. Therefore, the residents put the waste plastic containers in the garbage bag together with the kitchen waste and dispose of the waste plastic containers. However, if this is done, about 70 to 80% of the volume will be occupied by the waste plastic container, so to speak, it will carry air and the collection capacity will be diminished. Moreover, since high heat is generated during incineration, there are problems such as damage to the furnace. Recently, many local governments have revised their collection systems as described above. However, in any case, not only is it inconvenient for collection because the volume is much larger than the weight, but it is also inconvenient for each household to store it once or twice a month. The inconvenience brought out on that day is forced.

In order to solve the above problems, a compression device for a waste plastic container has been conventionally proposed.
Examples thereof include those that are forcibly compressed by lever operation (Japanese Patent Publication No. 6-47099) and those that are heated and compressed by hot air (Japanese Patent Laid-Open No. 5-92179).

[0005]

Among the above-mentioned compression devices for waste plastic containers, the lever operation type does not utilize the so-called lever principle, but the waste plastic container is crushed by a single operation. It takes a great deal of force to operate and puts an undue burden on the housewife.Moreover, the crushed state restores due to the elasticity of the waste plastic container, so lock it for a while and keep it in the crushed state. There was also a problem in terms of efficiency.

[0006] In the case of heating and compressing with hot air, it is transformed into a molten state by heat, but since foamed trays are so-called heat insulating materials, when the trays are stacked and crushed, Even if hot air is blown in the meantime, not only the hot air does not permeate uniformly, but also the amount of heat required for the deformation of the tray is insufficient due to the specific heat of air, so that the deformation takes time. Further, the crushing operation needs to be repeated many times, which is not always efficient. Also, due to this specific heat, in order to allow sufficient heat to pass, hot air must be 100 °
Since it is used at a high temperature of more than 100 ° C, such as C to 140 ° C, there is a danger in operation, and chlorine gas, which is highly toxic, may be generated depending on the type of plastic, which is also a safety issue. was there.

The present invention has been made in view of the above-described circumstances,
It is an object of the present invention to provide a compression device for a waste plastic container, which can crush the waste plastic container flatly and efficiently and does not require excessive labor at that time and can perform work safely.

[0008]

In order to achieve the above object, the present invention comprises a hot water tank having a heater for heating water, and a push plate for crushing a waste plastic container in hot water of the hot water tank. In the hot water tank, a receiving plate is provided as a base for crushing the waste plastic container, and a compressing device for the waste plastic container is configured by a spring or the like so that the waste plastic container is supported so as to be vertically movable.

[0009] In addition, a waste reservoir chamber into which the crushed waste plastic container is put is provided, and a hot water tank is provided in or adjacent to the waste reservoir chamber, and the waste plastic container is discarded from the receiving plate spouted from the hot water. The catch plate was designed to tilt when it jumps out so that it slides down into the reservoir.

Further, a safety lid is provided on the push plate via a vertical wall, and a handle is provided on the safety lid.

[0011]

[Operation] Since the compression device for the waste plastic container is configured as described above, place the waste plastic container on the receiving plate,
When pressed with a push plate from above, the push plate resists the elasticity of a spring or the like and crushes it while gradually dipping the waste plastic container in hot water. In this case, since the specific heat of water is large, it quickly softens and deforms very quickly, and in many cases, it deforms flat during the pushing operation.

Further, although the waste plastic container is light in weight and its position in which it floats in water cannot be determined, it is possible to surely carry out the immersion and deformation work in hot water in the sandwiched state. Further, when the crushing operation is finished, the waste plastic container is lifted while being sandwiched between the receiving plate and the pressing plate by the elastic force of the spring or the like, so that the deformation of the waste plastic container is not restored in the meantime, and the flat plastic container is not flattened. It can be pulled up in that state, and then touched with air at room temperature to establish a flat deformed state.
