Abstract

The utility model relates to a leakage-proof bottle cap which comprises an upper cap and a lower cap. The lower cap is fixed on a bottle body. The center of the top face of the lower cover extends outward to form a bottle mouth. The upper cap is arranged above the lower cap, and one side of the upper cap is connected with the lower cap. The top face of the inner side of the upper cap is provided with a leakage-proof ring which is wrapped at the upper end of the bottle mouth. A plurality of clamping grooves are arranged on the top face of the lower cap. Clamping blocks matched with the clamping grooves are arranged on the inner side of the upper cap. A plurality of fixing ribs are arranged on the periphery of the leakage-proof ring and on the top face of the inner side of the upper cap. When the upper cap is combined together with the lower cap in a pressed mode, the fixing ribs tightly clamp the bottle mouth. The leakage-proof bottle cap can effectively avoid leakage of liquid inside a bottle when carried outside.

Description

A kind of leakproof bottle cap

Technical field

The utility model relates to a kind of accessory of container bottle, the bottle cap on especially a kind of container bottle of carrying liquid.

Background technology

At present, the liquid bottles of generally using generally is made up of bottle, loam cake and lower cover, and a side of loam cake and lower cover links to each other through an elastic strip, and lower cover is fixed on the bottle.In liquid collecting bottle industry, in order to guarantee after transporting workshop, liquid that can not in the bottle spills because of factor such as transportation environment, all can add leak-proof device.For example add strip of paper used for sealing, perhaps in the fixing foil sealing of the bottle mouth position of bottle in the junction of loam cake and lower cover.The customer in use, tear strip of paper used for sealing or aluminium foil just can use.But, for some articles for daily use like toiletries, the time of often using is all long, and the number of times of use is also many; Go out to portably use toward the contact meeting, when carrying, these liquid bottles have not had the protection of strip of paper used for sealing and aluminium foil, and the liquid in the bottle will spill; If road environment is more abominable, perhaps receive the bump of other article, loam cake and lower cover will get loose; Liquid in the bottle will spill in a large number, and not only waste also can be polluted other article that carry.

The utility model content

The utility model purpose is to provide a kind of when going out to carry for the deficiency that overcomes prior art, prevents that loam cake and lower cover from getting loose, the leakproof bottle cap of avoiding liquid to spill.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of leakproof bottle cap, comprise loam cake and lower cover, said lower cover is fixed on the bottle, and in the end face of lower cover in the heart, be outward extended with bottle neck; Be covered on the top of lower cover on said, and a side of loam cake links to each other with lower cover; Also be provided with the leakproof ring on the inboard end face of said loam cake; Said leakproof ring wraps the bottle neck upper end; Also have a plurality of draw-in grooves on the end face of said lower cover; The inboard of said loam cake is provided with the fixture block that matches with draw-in groove; On the inboard end face of said loam cake, be positioned at the leakproof ring around also be provided with a plurality of fixing ribs; When said loam cake and lower cover pressing, fixing ribs chucking bottle neck.

Preferably, said fixing ribs is four.

Preferably, a side of said loam cake also is provided with opening groove.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

A kind of leakproof bottle cap of the utility model scheme; End face at loam cake is provided with the leakproof ring that tightly wraps bottle neck, and the inboard of loam cake also is provided with the fixing ribs that can tighten bottle neck, in addition under cover and also have a plurality of draw-in grooves; On the fixture block that covers and the cooperation of draw-in groove; Avoided loam cake and lower cover to take place to become flexible, when going out to carry, avoided spilling of bottle interior liquid effectively because of the external environment influence.

Description of drawings

Below in conjunction with accompanying drawing the utility model technical scheme is described further:

Accompanying drawing 1 is the perspective view of the utility model leakproof bottle cap when opening;

Accompanying drawing 2 is the cutaway view of the utility model leakproof bottle cap when closure;

Wherein: 1, lower cover; 2, loam cake; 3, bottle neck; 4, leakproof ring; 5, draw-in groove; 6, fixture block; 7, fixing ribs; 8, opening groove.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.

Accompanying

drawing

1,2 is the described a kind of leakproof bottle cap of the utility model, comprises loam cake 2 and lower cover 1, and said lower cover 1 is fixed on the bottle (not shown), and in the end face of lower cover 1 in the heart, be outward extended with bottle neck 3; Said loam cake 2 is located at the top of lower cover 1, and a side of loam cake 2 links to each other with lower cover 1; Also be provided with leakproof ring 4 on the inboard end face of said loam cake 2; Said leakproof ring 4 wraps the upper end of bottle neck 3; Also have two draw-in grooves 5 on the end face of said lower cover 1; The inboard of said loam cake 2 is provided with the fixture block 6 that matches with draw-in groove 5; On the inboard end face of said loam cake 2, be positioned at leakproof ring 4 around also be provided with four fixing ribs 7; When said loam cake 2 and lower cover 1 pressing, fixing ribs 7 chucking bottle necks 3; One side of said loam cake 2 also is provided with opening groove 8.Downwards during pressing loam cake 2; The leakproof ring 4 of loam cake 2 end faces will tightly wrap bottle neck 3, and inboard fixing ribs 7 and the gap between the bottle neck 3 of loam cake 2 is more and more littler, when loam cake 2 and lower cover 1 are closed together; Send loud, high-pitched sound one, this moment, fixing ribs 7 tightened bottle neck 3 firmly; In addition, draw-in groove 5 on the lower cover 1 and the fixture block 6 on the loam cake 2 have avoided loam cake and lower cover to take place to become flexible because of the external environment influence, when going out to carry, have avoided spilling of the interior liquid of bottle effectively.

Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
