Tight nozzle cover

Abstract

The invention discloses a tight nozzle cover. The tight nozzle cover comprises a container cover, a wrench rod body, a silica gel tray and a suction nozzle head screwed on a container opening, wherein an annular clamp position is arranged in the middle of the wrench rod body, the wrench rod body is provided with a wrench rod and a water outlet rod, the water outlet rod is contained in a cavity of the silica gel tray, at least one first water outlet hole is formed in the upper edge of the outer side of the water outlet rod, the container cover is connected with the suction nozzle head in screwing mode, an annular retaining edge for the annular clamp position to lean is arranged on the inner wall of the cavity of the silica gel tray, an outer annular clamp position is arranged on the upper edge of the outer side of the silica gel tray, a second water outlet hole identical with the water outlet rod is arranged at the bottom of the cavity of the silica gel tray, and a hanging ring clamped with the outer annular clamp position is arranged on the inner wall of a through hole of the suction nozzle head. After the tight nozzle cover is opened, the container opening can be automatically sealed when a person does not drink water in a container with the tight nozzle cover. Additionally, the tight nozzle cover is simple in structure and convenient to use.

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
