Description

No-spout lid that opens and closes automatically

technical field

The present invention relates to a container, in particular to a non-spout lid which can be opened and closed automatically on the opening of the container.

Background technique

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 the container body has a certain strength. Doing so will increase the consumption of plastic raw materials , Increase the product cost, because the product with certain thickness cannot be folded or compressed, will take up a large amount of space.

Contents of the invention

The purpose of the present invention is to provide a non-spout lid which can automatically open and close automatically to seal the mouth of the container when it is opened and not for drinking.

In order to solve the above-mentioned defects in the prior art, the technical solution provided by the present invention is: a leak-proof lid that can be opened and closed automatically, including a screw-on container cover, the top surface of the screw-on container cover has a hole, the The hole is equipped with a wrench body that can automatically discharge water after being pulled, and can be automatically closed after being released; The lower end of the lever body is provided with a water outlet assembly for opening and closing the water outlet of the container, and the middle part of the inner side wall of the hole is provided with an annular rib against which the snap-fitting groove abuts. When the lever body is pulled upwards, the bottom surface of the clamping groove abuts against the annular rib, and when the lever body retracts toward the hole, the sealing end cover covers the opening of the hole.

As an improvement of the leak-proof mouth cover that can be automatically opened and closed in the present invention, the water outlet assembly includes a cylindrical flexible bottom plug that can automatically return to its position after being bent, and the side wall of the flexible bottom plug is provided with At least one first slit which opens and closes automatically.

As an improvement of the non-spout lid that can be opened and closed automatically in the present invention, when the trigger body is pulled, the flexible bottom plug touches the inner side wall of the screw-on container lid and is squeezed and deformed, so The first notch is opened, the trigger body is released, and the first notch is automatically reset and closed.

As an improvement of the non-spout cover that can be automatically opened and closed in the present invention, the water outlet assembly includes a cylindrical rigid bottom plug, and the upper end of the rigid bottom plug is provided with a plurality of first water outlet holes at intervals. The lower end of the rigid bottom plug is provided with a tapered tapered sealing lower end.

As an improvement of the non-spout cover that can be opened and closed automatically in the present invention, an elastic inner cover extends from the opening edge of the hole into the container, and a second water outlet hole is provided at the bottom of the inner cover. When the wrench body retracts toward the hole, the rigid bottom plug seals the second water outlet hole, and when the wrench body is pulled upwards and pulled, the second water outlet hole opens and connects with the The first water outlet hole is connected.

As an improvement of the non-spout cover that can be opened and closed automatically in the present invention, the water outlet assembly includes multiple pieces of extrusion elastic pieces and an elastic and cylindrical water outlet valve, and the plurality of pieces of extrusion elastic pieces are arranged at intervals At the bottom of the trigger body, the extruded shrapnels all extend into the water outlet valve, and the outer upper edge of the water outlet valve is provided with an annular clamping position that engages with the annular rib, and the water outlet valve At least one second notch is provided on the outer lower edge of the outer side.

As an improvement of the non-spout cover that can be opened and closed automatically in the present invention, when the trigger body is pulled, the extrusion shrapnel presses the inner wall of the water outlet valve, the second slot opens, and the The second notch is closed when the lever body is pulled.

Compared with the prior art, the advantages of the present invention are: the present invention has an automatic sealing function, and due to the action of the flexible bottom plug, when the trigger body is pulled, the flexible bottom plug is against the side wall of the hole and deformed , the opening on the flexible bottom plug is opened, and the liquid in the bottle flows out from the opening. When the trigger body is released, the flexible bottom plug automatically resets, the opening is automatically closed, and the liquid in the container will not flow out from the opening. Prevent the liquid in the container from flowing out automatically when not drinking or when the container body is knocked over. When not in use, the wrench body can be retracted into the hole, and the wrench body seals the hole of the screwed container cover to prevent liquid It can flow out and pollute the wrench body. Due to the above-mentioned sealing effect, the wall thickness of the container can be greatly reduced. When the container is under pressure, the liquid in the container will not flow out from the outlet hole of the container; it can greatly reduce the consumption of plastic raw materials. The use saves product cost and is convenient for consumers to use.
