Leakless vessel cover capable of being opened and closed automatically

Abstract

The invention discloses a leakless vessel cover capable of being opened and closed automatically. The leakless vessel cover capable of being opened and closed automatically comprises a rotary vessel lid, a hole is formed in the top face of the rotary vessel lid, a pull rod body which can make water come out by pulling the pull rod body and stop the water by loosening the pull rod body is installed in the hole, the middle of the pull rod body is provided with a clamping groove, the upper end of the pull rod body is provided with a sealed end cap which is matched with the hole, the lower end of the pull rod body is provided with a water output component used for opening and closing a water outlet of a vessel, an annular rib which is used for the clamping groove to abut against is arranged in the middle of the inner side wall of the hole, when the pull rod body is pulled out upwards, the bottom face of the clamping groove abuts against the annular rib, and when the pull rod body is retracted inwards, the sealed end cap covers the opening of the hole. After the leakless vessel cover capable of being opened and closed automatically is opened, when drinking is not needed, the vessel opening can be automatically sealed.

Description

technical field [0001] The invention relates to a container, in particular to a non-spout cover which can be opened and closed automatically on the opening of the container. Background technique [0002] In the prior art, the container lid installed on the container opening has only a single function of opening and covering, for example: the lid on the beverage container is screwed on the container mouth in a screw-in manner, when opened, if the container If the drink is not finished and the drink in the container needs to be taken away, the cover must be re-screwed by hand. If the cover is not closed, the drink in the drink container will be easily contaminated. When the container body is overturned, the liquid in the container will Leakage. In addition, in order to prevent the liquid in the container from flowing out of the container mouth automatically when the container is under pressure, it is usually necessary to increase the thickness of the container body so that t...

Problems solved by technology

[0002] In the prior art, the container lid installed on the container opening has only a single function of opening and covering, for example: the lid on the beverage container adopts screw-on Screw on the mouth of the container in the same way. When it is opened, if the beverage in the container is not finished and needs to be taken away, the lid must be re-screwed by hand. If it is not closed, the beverage in the beverage container will be easily Contamination, when the container body is overturned, the liquid in the container will leak out. In addition, in order to prevent the liquid in the container from flowing out of the container mouth automatically when the container is under pressure, it is usually necessary to increase the thickness of the container body so that the container The body has a certain strength. Doing so will increase the consumption of plastic raw materials and increase the cost of the product. Since a product with a certain thickness cannot be folded or compressed, it will take up a lot of space
