Auxiliary stopper for sealing container

More particularly, the present invention relates to an auxiliary stopper for sealing a container, and more particularly, a container containing liquid contents such as medicines or organic fertilizer is inserted into the inside of the container stopper so as to close the container stopper, Which is provided with a filtration unit to prevent the leakage of liquid contents and to allow the gas to pass therethrough.

In general, a container stopper is mounted at an inlet of a container containing contents such as liquid, powder, granules, etc., and serves to prevent the contents from being discharged to the outside or coming into contact with outside air.

The sealing cap, which is one kind of the container stopper, is used for sealing the container containing the contents and preventing the contents from being deformed or replaced when circulating the container, so that the sealed container can not be opened at will. It is easy to recognize.

On the other hand, when the container has a relatively large capacity, the discharge port is not injected to a certain size, so that the discharge port is incompletely sealed, and the contents are leaked to the outside when the sealed container is transported.

In order to solve this problem, a hemispherical auxiliary cap is conventionally used, which is formed by a ring-shaped foam packing made of a PE material so as to press-seal the upper end of the discharge port to prevent leakage of the contents or to seal the inner circumference of the side of the discharge port have.

However, the ring-shaped foam packing has a one-time sealing ability when the outlet of the container is hermetically sealed, but the contents leak to the outside when the container is repetitively closed due to a pressing phenomenon.

In addition, the hemispherical auxiliary stopper has a problem in that the outlet of the container is not constant and the tightening force is insufficient to leak the contents, or the auxiliary stopper must be manufactured according to the radius of the outlet, There is a problem that this is relatively large.
