Abstract
The present invention relates to an opening and closing device for an automatic cap for a liquid container, which includes a container (10), a cap (20) which is screwed onto the inlet portion of the container (10), and an opening and closing member (30) which is disposed in the container (10) through the cap (20) and the inlet portion of the container (10) such that, when the container (10) is pressed from the outside, the container (10) can remain closed while contents are discharged. According to the present invention, the contents in the container can be automatically discharged and the container can be closed without removing the cap which is the lid of the container; the cap can be conveniently sealed so that the contents do not leak out even when the container is pressed during shipping or during transport for travel; and during use, the contents can be automatically discharged and the container remain closed just by pressing the container after releasing the seal.
