Automatically opening and closing leakage-proof nozzle cap

Abstract

The invention discloses an automatically opening and closing leakage-proof nozzle cap comprising a screwing bottle cap. A hole is opened in the top surface of the screwing bottle cap. A water outlet component which can discharge water after being pulled and can be automatically closed after being released is installed inside the hole. Due to the fact that the outer wall of a suction pipe component firmly sticks to a reversed cone shaped water outlet hole, the fluid inside the bottle cannot outflow from the reversed cone shaped water outlet hole. When a user wants to drink the liquid, the upper end of the suction pipe can be pulled, the lower end of the suction pipe can move obliquely at the same time, a pipe presses against the reversed cone shaped water outlet hole can pry up the reversed cone shaped water outlet hole, thereby deforming and enlarging the aperture of the hole, and the fluid inside the bottle can flow into a hollow frustum through the water outlet hole and then flow outside the bottle through the inner hole of the pipe after flowing into the water outlet of the pipe, thereby achieving the drinking upon opening the bottle; when releasing the suction pipe component, the suction pipe component returns to a vertical state, thereby achieving an automatic closing function. The automatically opening and closing leakage-proof nozzle cap is clean and sanitary, and is convenient to carry the bottle.

Description

technical field [0001] The present invention relates to containers, and in particular to a leak-tight cap for an opening of a container that can be automatically opened and closed. Background technique [0002] In the prior art, the bottle cap installed on the opening of the container has only a single function of opening and closing. For example, the cap on the beverage bottle is screwed on the bottle mouth by screwing. If the beverage is not finished, the beverage in the bottle needs to be taken away, and the lid must be re-screwed by hand. If it is not covered, the beverage in the beverage bottle will be easily contaminated. Leaks, in addition, are inconvenient to move and carry. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a leak-tight cap that can automatically open and close the bottle mouth after opening and can automatically seal the bottle mouth when not drinking. [0004] Provides a leak-tight cap that can be a...
