Abstract

The utility model relates to a clean bottle cap, and belongs to the technical field of bottle-type containers. The bottle cap comprises a covering cap consisting of a cap top and a brim and a cap core. A downward cork is manufactured inside the cap top. The cap core primarily consists of an external column and a core nozzle arranged in the middle of the cap core. The external column is matched with a bottle jack, and is manufactured with a seal structure. The core nozzle is manufactured with a central through hole. The inside diameter of the through hole is matched with the outside diameter of the cork in a sealed way. The through hole extends upwards out of a V-shaped drainage nozzle inclined toward one side. The core nozzle is connected with the inner wall of the external column through a centroclinal curved pyramidal face, thus forming an annular liquid receiving chamber. At least one communicating structure is arranged between the liquid receiving chamber and the central through hole. The clean bottle cap has simple structure and can be opened conveniently. Accordingly, the clean bottle cap can effectively prevent liquid from leaking out or through, and keep the environment clean.

Description

Clean-keeping bottle cover

Technical field

The utility model relates to a kind of bottle cap, and especially a kind of structural development of bottle cap belongs to the bottle type container technical field.

Background technology

Bottle type container is extensively at daily life (holding of oil, vinegar, soy sauce, liquid condiment, drinks), chemical frbre industry (splendid attires of benzene, potassium, aldehyde, amine, alcohol etc.), and numerous areas such as agricultural, medical and health.Yet, understand according to the applicant, the various in the market lids of leak free bottle type container that need not only need push up, draw when opening with finger, even with cutter, cut and lever up or cut and can open, usually cause the finger can injured bleeding, and when toppling over, liquid in the bottle is easy to the water clock that leaks, cause environmental pollution, particularly harmful liquid of high molecular compound and so on also can influence healthy.

Though people have carried out various improvement to the structure of bottle cap, all fail to solve the above-mentioned problem that exists with simple structure.

The utility model content

The purpose of this utility model is: at the problem that above prior art exists, propose a kind of simple in structure, open convenient, sealing is reliable, and the Clean-keeping bottle cover of the water clock of can avoiding leaking.

In order to reach above purpose, the technical scheme of the utility model Clean-keeping bottle cover is: comprise the block and the cover core that are made of the crown and the brim of a hat, described crown inside is shaped on downward stick harness, described cover core mainly is made of the core mouth at outside cylinder and its middle part, described outside cylinder and bottleneck match, and be shaped on hermetically-sealed construction, described core mouth is shaped on central through hole, the internal diameter of described through hole and the external diameter of described stick harness are sealed and matched, described through hole extends upward the V-arrangement drainage mouth towards lopsidedness, described core mouth is connected by the centroclinal bent conical surface with the outside cylinder inwall, forms the sap cavity that connects of ring-type, and there is at least one place connectivity structure in described connecing between sap cavity and the central through hole.

Further improving of above technical scheme be, described the brim of a hat periphery is shaped on flange down, and the upper surface of described cover core outside cylinder is shaped on the expansion limit that matches with the brim of a hat periphery flange.

During use, cover core is inserted on the bottleneck.When toppling over bottle interior liquid, draining hole can effectively be avoided leaking, even a small amount of water clock is arranged, also can fall into and connect sap cavity, and in intercommunicating pore flows back to bottle, thereby thoroughly eliminate weeping.After covering block, the central through hole of cover core is blocked by stick harness, connects sap cavity and is covered by the brim of a hat, especially have the brim of a hat turnup structure after, airtight shutoff is reliable.This shows that the utility model is simple in structure, it is convenient to open, and can effectively avoid the leaked liquid water clock, thereby guarantees the environment cleaning.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is the birds-eye view of cover core among Fig. 1.

The specific embodiment

Embodiment one

The Clean-keeping bottle cover of present embodiment comprises block 1 and cover core 2 as depicted in figs. 1 and 2.Wherein blocking a shot 1 is made of crown part 1-4 and the brim of a hat part 1-2, and the inside of crown 1-4 is shaped on downward stick harness 1-1, and the periphery of the brim of a hat 1-2 is shaped on flange 1-3 down.Cover core 2 mainly is made of the core mouth 2-5 at outside cylinder 2-1 and its middle part, and outside cylinder 2-1 and bottleneck match, and are shaped on four road seal ring 2-2, and its upper surface is shaped on the expansion limit 2-3 that matches with the brim of a hat periphery flange 1-3.Core mouth 2-5 is shaped on central through hole 2-4, and the external diameter of the internal diameter of this through hole and stick harness 1-1 is sealed and matched, and this through hole extends upward the V-arrangement drainage mouth 2-6 towards lopsidedness.Core mouth 2-5 is connected by centroclinal bent conical surface 2-8 with the outside cylinder inwall, and what form ring-type meets sap cavity 2-9, connects between sap cavity 2-9 lowest part and the central through hole 2-4 and is shaped on connected entrance 2-7.

During use, cover core inserts bottleneck, and block is fastened on the cover core, on every side sealing fully.When liquid bottles is in the drainage mouth down the time, air can enter in the bottle through connected entrance, and the bottle inner and outer air pressure equates that liquid can flow out smoothly; When stopping to topple over, remaining liquid can pass back into the bottle from connected entrance by nature.Bottleneck does not have to drip to be hung, and can keep hygienically clean.When liquid bottles is in the drainage mouth up the time, can play the effect that retardance liquid overflows.

Present embodiment driving fit performance is good, can anticorrosive and minimizing volatilization.Health is played prevention and protective effect, other article are not had destructiveness.Its design is ingenious, elegant in appearance, and the Yi Kaiyi lid is convenient to injection mo(u)lding, can keep repeated use to be worth.

When being used in the diet aspect, the optional high density polyethylene (HDPE) of material, polypropylene, nontoxic, harmless to human body, have no side effect, and anti-corrosive properties is good.

When being used in aspect such as chemical frbre industry, agricultural, medical and health, the optional RPP of material has strong corrosion resistance.

In a word, the Clean-keeping bottle cover of present embodiment is easy to use, does not have and splashes and water clock, therefore compares with existing other bottle cap, has outstanding advantage.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
