Such products are those that are left in a natural environment or do not mix easily even when they are buried in the ground. They must be discarded in a state of collecting used products. It is very difficult to collect used products completely.

In other words, products discarded in amusement parks or beaches are still easy to collect, but products discarded in the mountains can not be picked up because they are difficult to collect, In order to collect the products one by one, there is a problem in that a lot of labor is mobilized, resulting in waste of manpower and economic loss.

Conventionally, in order to solve the above-mentioned conventional problems, paper made of wood as a main material is made to be in a container, and even if the used disposable container is discarded as it is, it decomposes when natural time passes, The inconvenience of collecting disposable containers abandoned in the environment is eliminated so that the natural environment is prevented from being damaged by the disposable container.

However, in this case, when the paper container is formed by using paper, a feedback phenomenon occurs due to the characteristics of the paper, and a crack occurs such as cracking of the paper. Therefore, There is a problem that the manufacturing cost increases.

Conventionally, a plurality of papers have been conveyed one by one through a conveyor belt, etc., and container vessels have been manufactured through a corrugating machine, a cutter and a molding machine. However, due to vibrations or various other factors generated in the conveyor belt itself, This is an impossible problem.
