Description

a cover

technical field

The utility model belongs to the technical field of bottle parts, in particular to a cover.

Background technique

Existing bottles, especially for bottle caps used to hold shampoo, shower gel and other bottles, sometimes fall down when the bottle is opened, and the liquid in the bottle will flow out from the discharge port, causing waste. In the open state, the prior art has poor sealing performance.

SUMMARY OF THE INVENTION

The purpose of the utility model is to overcome the disadvantage of poor sealing performance in the open state of the prior art, and propose a cover with good sealing performance in the open state.

In order to achieve the above object, the utility model adopts the following technical solutions:

A cover, comprising a connecting head connected to a bottle body, a discharge port located on the connecting head, and a cover body hinged on the connecting head at one end for sealing the discharge port, the connecting head is at a position close to the bottle body. An annular convex block is fixed on the side, and the convex block is located at the corresponding position of the discharge port. Two clamping sleeves, the outer edge of the second clamping sleeve is provided with a clamping block, the clamping sleeve is provided with a clamping groove at the corresponding position of the clamping block, and the clamping block is located in the clamping groove, and the second clamping sleeve is close to the convex block. One end is provided with a second ring-shaped snap groove, a ring cavity is formed between the second snap groove and the lower edge of the protruding block, a fixing ring is arranged in the ring cavity, and the discharge port is close to the side of the bottle body An elastic film is provided, the outer edge of the elastic film is connected to the fixing ring, and a discharge slit is arranged on the elastic film. The discharge slit is set on the elastic film. When the bottle falls down, if the liquid wants to flow out from the discharge slit, the liquid needs to exert a certain force on the elastic film to deform the elastic film and make the width of the discharge slit become larger. The discharge slit passes through the middle, and finally flows out from the discharge port; therefore, if the bottle body just falls down, the pressure of the liquid is not enough to cause the elastic membrane to be greatly deformed, and the liquid will not flow out and will not cause waste. And the ferrule, the second ferrule and the fixing ring are convenient for the installation of the elastic membrane.

Preferably, the elastic film is spherical, the side of the elastic film away from the bottle body is provided with an encrypted steel ball, the elastic film is attached to the encrypted steel ball, and a ring-shaped magnet is fixed on the inner side of the second ferrule, The elastic film is located between the encrypted steel ball and the magnet. The side of the magnet close to the elastic film is provided with an annular groove, and the groove is fixed to the elastic film. The inner diameter of the magnet is adapted to the discharge slit, so A limiting column is arranged on the side of the encrypted steel ball away from the bottle body, and the limiting column is fixedly connected to the inner side of the convex block. The densified steel balls further increase the sealing performance of the utility model. The magnets are used to adsorb the encrypted steel balls on the discharge seam. Even if the seam width of the discharge seam becomes wider due to long-term use, the liquid will not flow out of the discharge seam.

Preferably, a second limiting column is fixed on the cover body, and when the cover body cover is set on the connecting head, the end of the second limiting column passes through the discharge port and abuts against the encrypted steel ball. When the cover body is closed, the second limiting column abuts on the encrypted steel ball, which enhances the sealing performance in the closed state.

Preferably, the number of limit posts is four, and the limit posts are arranged in an annular array with the axis of the bump as the center. This makes the limiting effect on the encrypted steel balls more uniform.

Preferably, the discharge slit is in the shape of a cross. Simple structure.

Preferably, the elastic membrane and the fixing ring are made of silica gel. Silicone material is relatively soft.

Preferably, the elastic membrane and the fixing ring are integrally formed. Ease of production.

The beneficial effect of the utility model is that a discharge slit is arranged on the elastic film, and when the bottle falls down, if the liquid is to flow out from the discharge slit, the liquid needs to exert a certain force on the elastic film, so that the elastic film is deformed and released. When the width of the material seam becomes larger, it can pass through the middle of the discharge seam and finally flow out from the discharge port; therefore, if only the bottle body just falls down, the pressure of the liquid is not enough to cause the elastic film to be greatly deformed, and the liquid will not flow out. No waste. And the ferrule, the second ferrule and the fixing ring are convenient for the installation of the elastic membrane. The encrypted steel balls further increase the sealing performance of the utility model, and the encrypted steel balls are adsorbed on the discharge seam by magnets. Even if the seam width of the discharge seam becomes wider due to long-term use, the liquid will not flow out from the discharge seam, and it is durable. good sex.

Detailed ways

Below in conjunction with the accompanying drawings and specific embodiments, the present utility model is further elaborated:

Example:

Referring to Figures 1 to 4, a cover includes a connecting head 1 connected to the bottle body, a discharge port 3 located on the connecting head 1, and a cover hinged at one end on the connecting head 1 for sealing the discharge port 3 Body 2, the connecting head 1 is fixed with a ring-shaped bump 4 on the side close to the bottle body, the bump 4 is located at the corresponding position of the discharge port 3, and a clamping sleeve 5 is sleeved on the bump 4, The ferrule 5 is fixed on the connector 1, a second ferrule 6 is arranged inside the ferrule 5, and a clamping block 7 is arranged on the outer edge of the second ferrule 6, and the ferrule 5 is in the clamping block. 7 is provided with a card slot 8 at the corresponding position, the card block 7 is located in the card slot 8, and the end of the second card sleeve 6 close to the convex block 4 is provided with a second ring-shaped second card groove 9, the second card groove A ring cavity 10 is formed between 9 and the lower edge of the bump 4, a fixing ring 11 is arranged in the ring cavity 10, an elastic film 12 is arranged on the side of the discharge port 3 close to the bottle body, and the elastic film 12 The outer edge is connected to the fixing ring 11, and the elastic film 12 is provided with a discharge slit 13; the elastic film 12 and the fixing ring 11 are made of silicone material; the elastic film 12 and the fixing ring 11 are integrally formed; Cross-shaped; the elastic film 12 is spherical, the side of the elastic film 12 away from the bottle body is provided with an encrypted steel ball 14, the elastic film 12 is attached to the encrypted steel ball 14, and the inner side of the second ferrule 6 is fixed. There is a ring-shaped magnet 15, the elastic film 12 is located between the encrypted steel ball 14 and the magnet 15, the magnet 15 is provided with a ring-shaped groove 16 on the side close to the elastic film 12, and the groove 16 is connected to the elastic film 12. Fixed connection, the inner diameter of the magnet 15 is adapted to the discharge slit 13, and the side of the encrypted steel ball 14 away from the bottle body is provided with four limit posts 17, and the limit posts 17 are fixed on the inner side of the bump 4; The limit posts 17 are arranged in an annular array with the axis of the bump 4 as the center; the cover body 2 is fixed with a second limit post 18 , when the cover body 2 is covered on the connector 1 , the second limit posts 18 The end passes through the outlet 3 and abuts against the encrypted steel ball 14 .

Example principle:

When the cover 2 is opened, the encrypted steel balls 14 are adsorbed by the magnets 15. At this time, the encrypted steel balls 14 are attached to the elastic film 12. Even when the bottle falls down, the liquid in the bottle will not flow out of the discharge slit 13. After that, because the encrypted steel ball 14 blocks the discharge slit 13, the liquid will not flow out from the discharge port and will not cause waste.
