BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste container, and more particularly to a waste container capable of storing waste to be incinerated and incinerated after storage.

[0002]

2. Description of the Related Art Medical waste such as used syringes discharged from hospitals and the like, and infectious waste discharged from laboratories and the like to which infectious bacteria and the like are attached are classified into the following two types. Careless disposal as specially managed industrial waste is required because the three parties may be infected if carelessly touched.It is conventionally housed in a container dedicated to industrial waste and disposed of. It is incinerated at treatment facilities.

[0003] Conventionally, two types of waste containers, plastic and corrugated, have been used.
These containers will inevitably be incinerated in the near future.

[0004]

However, plastic containers emit harmful substances such as black smoke and hydrogen chloride gas emitted from vinyl chloride when incinerated. Needed. And there are few facilities equipped with such processing equipment, and there is a limit in the processing capacity of these industrial wastes.

[0005] In the case of plastic containers, there is a risk that the incinerator may be damaged because a large amount of heat is generated during incineration. Still further, plastics are heavy and inconvenient to transport because of their heavy weight, and waste treatment must bear the increased cost by the weight of the container because the disposal cost is calculated based on the weight. Did not.

On the other hand, a container made of corrugated cardboard is more advantageous than a plastic container in incineration and weight, but has problems in strength and manufacturing method. In terms of strength, since it is made of paper, it is necessary, for example, to have a multi-layered wall structure in order to prevent the injection needle from penetrating and being exposed to the outside even in the unlikely event of an accident. In addition, in order to ensure waterproofness, processing such as vinyl coating of the inner wall surface is performed.

[0007] Further, in terms of the manufacturing method, since it is made of paper, its manufacture and assembly are troublesome, resulting in high costs. That is, the conventional container increases the number of parts and the number of manufacturing steps, and causes a rise in cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is not to damage an incinerator when incinerated, to produce no black smoke and no harmful substances by incineration, to have a light weight and a strength. It is an object of the present invention to provide a waste container which is excellent in quality and can be easily molded and manufactured.

[0009]

In order to solve the above-mentioned problems, a waste container according to claims 1 to 3 of the present invention comprises:
It is made of a material containing polyethylene terephthalate (PET) as a main component, and this material is manufactured using recycled materials obtained by recycling a container using polyethylene terephthalate, for example, a so-called PET bottle.

[0010] This polyethylene terephthalate can be burned at a low temperature, is decomposed into carbon dioxide and water without generating harmful substances during combustion, generates less black smoke than polystyrene or the like, and remains unburned. Does not occur. Further, it is lighter in weight than plastic, can be easily formed like plastic, and has high strength and waterproofness.

Therefore, when used in a waste container which must be incinerated after use, all problems of the conventional waste container can be solved. In addition, the use of recycled materials can contribute to the recycling of PET bottles, which has recently become a social problem.

[0012] Here, the term "recycling" refers to recovering used containers made of polyethylene terephthalate after use.
After fine cutting, it is washed and dissolved to regenerate as a regenerated raw material.

The waste container according to claims 4 to 10 has a substantially rectangular box shape, and has a container body having an opening having a predetermined area at an upper portion thereof, and the opening is closed. A possible lid is provided.

Therefore, the opening can be temporarily tightened by the lid even in the use state between the start of use of the waste container and the time when the waste container is filled with the waste. As a result, for example, the lid can be opened only when the waste is discarded in the container, and after the container is filled with the waste, the lid can be fixed in a closed state and discarded.

Thus, the opening area of the opening in the use state can be reduced to a necessary minimum, and the infection or the like due to the contents discarded inward can be prevented.

In addition, even if the container is accidentally knocked down during use, it is possible to prevent the waste from jumping out of the container, and to prevent infection due to contact with the waste. Can be prevented.
