Description

No-spout lid that opens and closes automatically

technical field

The utility model relates to a container sealing device, in particular to a non-spout cover which can be opened and closed automatically on the opening of a 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.

Utility model content

The purpose of this utility model is, aiming at the above-mentioned defects of the prior art, to provide a non-spout lid that can automatically open and close when not drinking after opening, which can automatically seal the mouth of the container.

In order to solve the above-mentioned defects of the prior art, the technical solution provided by the utility model is: a non-spout cover 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, so A push rod body that can move up and down and has elasticity is installed in the hole; the upper end of the push rod body protrudes out of the hole, the lower end of the push rod body is provided with a water outlet rod, and the middle part of the push rod body An annular sealing edge is provided, and the inner wall of the hole is provided with an annular rib against which the annular sealing edge abuts. The opening edge of the upper end of the hole is sealed by a pull ring, and the pull ring covers the push rod body. On the upper end, the water outlet rod is provided with a plurality of first through holes for water outlet at intervals. When the push rod body is pushed to move downward, the liquid in the container will flow from the first through holes and screw the container cover in turn. out of the hole.

As an improvement of the automatic opening and closing mouthpiece cover of the present invention, the bottom of the inner side wall of the hole is provided with an annular baffle for preventing the push rod body from moving down too far.

As an improvement of the automatic opening and closing non-spout cover of the utility model, the edge of the annular sealing edge is inclined upward at a certain angle.

Compared with the prior art, the utility model has the advantages that: the utility model has an automatic sealing function, because the product adopts an elastic push rod body, when in use, pull the pull ring on the bottle cap and push the push rod body When moving down, the liquid in the container flows out from the first through hole and the hole on the screwed container cover in turn. Since the push rod body is provided with a ring-shaped sealing edge, when the downward pressure is released, the push rod body automatically resets. The ring-shaped sealing edge seals the opening of the bottle cap, and the liquid in the bottle will not flow out from the first through hole to the bottle cap hole. Due to the above-mentioned sealing effect, the wall thickness of the container can be greatly reduced. When the container is pressurized, the liquid in the container The liquid will not flow out from the water outlet hole of the container; the use of plastic raw materials can be greatly reduced, the cost of the product is saved, and it is convenient for consumers to use.

detailed description

Below just will further describe the utility model according to accompanying drawing.

As shown in Fig. 1, Fig. 2 and Fig. 3, a kind of non-spout lid that can be opened and closed automatically includes a screw-on container cover 1, and a hole 2 is arranged on the top surface of the screw-on container cover 1, and a hole 2 is arranged in the hole 2. A push rod body 3 that moves up and down and has elasticity; the upper end of the push rod body 3 extends out of the hole 2, the lower end of the push rod body 3 is provided with a water outlet rod 4, and the middle part of the push rod body 3 is provided with an annular sealing edge 5, and the hole The inner wall of the hole 2 is provided with an annular rib for the annular sealing edge to lean against. The opening edge of the upper end of the hole 2 is sealed with a pull ring 6. The pull ring 6 covers the upper end of the push rod body 3. A plurality of The first through hole 7 for water outlet, when pushing the push rod body 3 to move downward, the liquid in the container flows out from the first through hole 7 and the hole 2 on the screwed container cover 1 in sequence.

Preferably, the bottom of the inner side wall of the hole 2 is provided with an annular stopper 8 for preventing the push rod body 3 from moving down too far. When the push rod body 3 moves downward too far, the bottom of the push rod body 3 will abut against the annular blocking piece 8 .

Preferably, the edge of the annular sealing edge 5 is inclined upward at a certain angle. The edge of the annular sealing edge 5 is set upwards, which can improve the sealing effect. The setting of the annular sealing edge 5 can be used for gas sealing. The gas in the bottle has a certain pressure effect, which can make the annular sealing edge seal Better results.

The utility model has an automatic sealing function. Since the product adopts the elastic push rod body 3, when in use, the pull ring 6 on the bottle cap is pulled open, and when the push rod body 3 is pushed to move downward, the liquid in the container moves from The first through 7 holes and the hole 2 on the screwed container cover 1 flow out. Since the push rod body 3 is provided with an annular sealing edge 5, when the downward pressure is released, the push rod body 3 automatically resets, and the annular sealing edge 5 seals Close the bottle cap opening, the liquid in the bottle will not flow out from the first through hole 7 to the bottle cap hole. Due to the above sealing effect, the wall thickness of the container can be greatly reduced. When the container is pressurized, the liquid in the container will not flow out. It will flow out from the water outlet hole of the container; it can greatly reduce the use of plastic raw materials, save product costs, and is convenient for consumers to use.

According to the disclosure and teaching of the above specification, those skilled in the art to which the utility model belongs can also make appropriate changes and modifications to the above embodiment. Therefore, the utility model is not limited to the specific implementation manners disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
