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. |

1. An opening and closing device of an automatic cap for a liquid vessel comprising:
a vessel; a cap which is screwed with an inlet part of the vessel and includes a central hole; and an opening and closing member installed within the vessel between the cap and the inlet part of the vessel for extracting contents when pressing the vessel from outside, wherein the opening and closing member comprises: a rotation opening and closing member including a lower part, a top surface, a cylindrical rotation part that is protruded from the lower part toward the top surface, such that the cylindrical rotation part is configured to be inserted into the central hole of the cap, the lower part including a flange part that has a larger diameter than the cylindrical rotation part and is configured to be seated on an inner peripheral surface of a lower portion of the cap, a pair of projection plates that are protruded symmetrically and vertically on both sides of an inner peripheral surface of the cylindrical rotation part, and a liquid discharging hole that is disposed on the top upper surface; an up-down movement bar member in a bar shape, including two upper end projection bars which are protruded as a pair on both sides of an upper part thereof, a pair of gaps disposed on each side of the upper part and defined by the pair of two upper end projection bars, wherein the pair of the projection plates of the rotation opening and closing member are inserted into the pair of the gaps respectively such that the up-down movement bar member is rotated according to the rotation of the rotation opening and closing member, a pair of lower end projection bars that are protruded at a lower end of the up-down movement bar member in a same direction as the two upper end projection bars, a pair of lower side projection bars which are protruded toward outside from a lower side surface of the up-down movement bar member and have circular plates disposed at an end of each of the pair of lower side projection bars, respectively, and a circular outer peripheral groove that is formed above the pair of lower end projection bar; and a vessel inner member including a circular part into which an upper end of the up-down movement bar member is inserted through an upper hole disposed at a center of the vessel inner member, the circular part being disposed between the cap and the vessel, a band type-member having a U shape and connected to a lower portion of the circular part, a lower slit hole disposed at a center of a lower end surface of the band-shape member and into which the lower end projection bar of the up-down movement bar member is inserted, and an inner side projection bar having an inner side circular plate configured to engage with one of the circular plates of the up-down movement bar member. |
