Abstract

The utility model relates to a bottle cap, in particular to a multi-functional vacuum bottle cap. The top of a plug is connected with the top of an exhaust check valve cap integrally and fixedly, and a sealing thin film is coated on the outer wall of the plug, so the chance of the ventilation of air in a piston and air on a bottle is reduced; and a thread which can be tightly connected with the outer wall of a bottle body in a suspended way is formed on the inner wall of the lower part of the exhaust check valve cap; the thread can be tightly meshed with the outer wall of the bottle body; when the original sealing of a product is damaged, and the product is opened, air in the package of the product can still be pumped when the multi-functional vacuum bottle cap is used; meanwhile, the sealing effect can be kept, long-time vacuum preservation can be realized, and the multi-functional vacuum bottle cap can adapt to any bottle and is used as a common bottle cap according to the requirements, and has a wind application range.

Description

Multi-functional bottle cap

Technical field

The utility model relates to a kind of bottle stopper, particularly a kind of multi-functional true empty cap.

Background technology

In daily life, run into through regular meeting: not necessarily can both finish off at every turn, eat up such as medicine, food, the red wine of often drinking, foreign wine and various fruit juice and soda, common people's way is exactly simply first wife's stopper to be covered.As everyone knows, after bottle stopper opens and uses, because the entering of air; The long-term storage of placing can make the product quality effect reduce greatly, and contains some bacteriums or smell etc. in the air, will make product generation oxidizing action; Thereby cause the rotten of medicine, food and wine or beverage; Caused the rotten of a large amount of product waste, particularly medicine, some rotten back is in case be eaten and can cause very big injury to human body.In order to solve by the fresh-keeping problem of Kaifeng article; There is the insider to invent all kinds of bottle stoppers that vacuumize; Though these bottle stoppers can play fresh-keeping effect to a certain extent; But because product seals and the complete set type vacuum freshness retaining is restricted, so the alerting ability of fresh-keeping time and vacuum freshness retaining also is restricted.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of prior art, and a kind of good sealing effect is provided, and the vacuum freshness retaining time is long, and multi-functional bottle cap applied widely.

The utility model comes existing through following technical scheme: multi-functional bottle cap; Comprise that a center is cavity and cylindrical circular lid, the piston that is used to stop up the plug of bottleneck and is positioned at the lid cavity; Be provided with seal ring between piston and lid, an aspirating hole that cavity is communicated with the plug outside is arranged in the described plug, described piston is connected with a piston rod; Piston rod is inner to be connected with piston; Lid is stretched out in the outer end, in piston, is provided with an exhaust check valve lid that makes the unidirectional ventilation of deflation hole, it is characterized in that: its top of described plug and the affixed one of exhaust check valve hd top face; The outer wall of plug coats one deck sealing film, and exhaust check valve lid lower inner wall is provided with and can tightly hangs the screw thread that connects with the bottle outer wall.

The beneficial effect of the utility model: the utility model is on the one hand with plug top and the affixed one of exhaust check valve hd top face, and the outer wall of plug coats one deck sealing film, can reduce the chance of interior air of piston and bottle inner air convection like this; On the other hand; Exhaust check valve lid lower inner wall be provided with can with the tightly outstanding screw thread that connects of bottle outer wall, screw thread can with the tightly interlock of bottle outer wall, after the former sealing of product is destroyed unlatching; Adopt the multi-functional bottle cap of said structure; Still can reach the air of taking out in the packing of product, can also keep sealing effectiveness simultaneously, realize long-time vacuum freshness retaining; And it can use as common bottle cap according to any bottle of demand adaptation, and range of use is wide.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed elaboration:

Referring to Fig. 1 and Fig. 2; Multi-functional bottle cap comprises that a center is cavity and cylindrical circular lid 1, the piston 3 that is used to stop up the plug 2 of bottleneck and is positioned at the lid cavity, and 1 of piston 3 and lid are provided with seal ring 4; An aspirating hole 5 that cavity is communicated with the plug outside is arranged in the described plug 2; Described piston 3 is connected with a piston rod 6, and piston rod 6 the inners are connected with piston 3, and lid 1 is stretched out in the outer end; In piston, be provided with an exhaust check valve lid 7 that makes the unidirectional ventilation of deflation hole; Plug 2 its tops and exhaust check valve cover the affixed one of 7 end faces, and the outer wall of plug 2 coats one deck sealing film 8, and exhaust check valve covers 7 lower inner wall and is provided with and can tightly hangs the screw thread 9 that connects with the bottle outer wall.

According to the announcement and the instruction of above-mentioned specification sheets, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present invention some modifications and the change of the utility model.In addition, although used some specific terms in this specification sheets, these terms are explanation for ease just, the utility model is not constituted any restriction.

Claims
