- a kind of shackle closure

Technical field

The utility model relates to a screw cap type container sealing structure, in particular to a screw cap type bottle cap structure.

Background technique

The existing cap-type caps are widely used in the sealing of various kinds of articles in daily life, such as various types of beverage bottles, medicine bottles, wine bottles, edible seasonings (sauce, vinegar) bottles, etc. Cap bottle cap. When the cap is tightened, the sealing ring at the top of the cap is in close contact with the top end of the bottle to form a seal to isolate the inside and outside of the bottle; when the cap is first unscrewed, the pseudo-ring at the bottom of the cap is opened. The protruding ring of the outer peripheral surface of the lower part of the bottle mouth is lapped, and the pseudo dummy ring at the bottom of the bottle cap is separated from the bottle cap body by the vertical top stopping force applied by the protruding ring.

In the existing cap-type cap structure, the lower end surface of the cap body has no contact with the upper end surface of the collar on the bottle mouth, and has the disadvantages of: small sealing range, insufficient safety and sanitation, that is, when people drink or dump the contents of the bottle The liquid in the mouth or bottle of the person usually comes into contact with the part below the top of the bottle mouth and above the ring, and this part is outside the sealing and sealing range, and is not sealed and protected. This part is in the production of beverages. Transportation, inventory, and sales may be contaminated by dust, germs, or harmful substances in the air, posing a potential hazard to the health of the consumer.

Summary of the invention

The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art mentioned above, and to provide a safe and sanitary capping cap structure which is simple in structure, convenient in implementation, large in sealing range, and can seal the lower part of the bottle mouth and above the collar. .

The purpose of the utility model is achieved by the following scheme: The capping cap structure comprises a bottle mouth and a lid body, wherein the outer peripheral surface of the bottle mouth is screwed with the inner surface of the cap body, and the upper end surface of the cap body and the top end of the bottle mouth A first sealing ring is disposed between the lower end of the cover body and a dummy ring. The outer peripheral surface of the lower portion of the bottle mouth is provided with a protruding ring, and the protruding ring is nested in a ring groove formed by a lower end of the cover body and a dummy ring. The collar is sealingly connected to the lower end of the cover.

In order to better implement the present invention, the lower end of the cover body and the pseudo-pseudo ring are connected to the outer ring, and the protruding ring is sealingly connected with the lower end of the cover.

The upper end surface of the protruding ring is in contact with the lower end surface of the cover body.

The protruding ring is sealingly connected to the lower end of the cover body by at least one second sealing ring, and the second sealing ring may be independent or integrated with one of the lower end of the cover body and the protruding ring, the second sealing The longitudinal profile of the circle includes a V shape, a U shape, a rectangular shape, or a trapezoidal shape. The working principle of the utility model is: a first sealing ring is arranged between the upper end surface of the cap body and the top end of the bottle mouth to form an upper seal, and the protruding ring is sealedly connected with the lower end of the cap body to form a lower seal, thereby making the capping type The cap structure has two seals, and the parts above the top of the bottle mouth and above the ring are better sealed and protected from external environment pollution.

The utility model has the following advantages and effects compared with the prior art:

(1) Safe and hygienic, reliable to use, the utility model can better seal the lower part of the bottle mouth and above the protruding ring, and has a large sealing range, which can effectively prevent the contact between the mouth of the consumer and the liquid in the bottle from being contaminated, Improve the safety and hygienic performance of the capping cap and better protect the health of the consumer;

(2) The structure is simple and easy to implement. The structure of the utility model has little change compared with the existing cap-type cap structure. The use of the cap-type cap does not require major changes to the existing filling production line, and the innovation cost of the enterprise Low, easy to implement;

(3) Wide application range, the structure of the utility model can be widely applied to the cap-type container sealing structure with high sealing requirements, such as various beverage bottles, medicine bottles, wine bottles, edible seasonings (sauce, vinegar) bottles, etc. .
