Abstract
The utility model discloses a bottle cap structure which comprises a bottle cap body, wherein an annular fastener is arranged on a top wall in the bottle cap body in a downward bulged manner, at least one concealed air hole is formed on an inside wall of the top wall in the bottle cap body in an inward bulged manner, penetrates through the annular fastener and is formed in an inner wall of the annular fastener in a bulged manner, and a hydrophobic and oleophobic film is contacted and connected with the lower surface of the annular fastener and is limited at the lower part of the annular fastener by a lower clamp ring for assembling. The bottle cap structure has the characteristics that the structure is good in sealing persistence, water-tight and oil-tight, dust-proof and bacteria-proof, and breathable.
Description
Technical field
The utility model relates to a kind of Bottle cap structure.
Background technology
Present field of food, food is in packing later storage and sales process, because the zone of selling is different, food has experienced the variation of temperature and air pressure, cause the pressure variation of packaging for foodstuff leakproof tank inside, perhaps, food itself also can produce some gases, above problem causes packing container dilatational strain or shrinkage distortion, above situation will occur such as food such as pickles etc.; For addressing the above problem, food processing enterprises have adopted open packaging for foodstuff, but the problem that leaking has appearred again in this packing, leakage of oil and bacterium contamination by dust cause food spoilage.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Bottle cap structure, and it is good that it has the sealing persistence, and dust and bacterium are not advanced in water-tight leakage of oil, and the characteristics that can breathe freely.
For solving the problems of the technologies described above, the utility model adopts following technical proposals: a kind of Bottle cap structure comprises body of the bottle lid; Described body of the bottle lid inner roof wall is equipped with the ring-type buckle downwards, at least one built-in air extractor vent inwardly is equipped with in madial wall position near described body of the bottle lid inner roof wall, this built-in air extractor vent passes ring-type buckle inwall and is based in the ring-type buckle inwall, one hydrophobic oleophobic film and ring-type buckle lower surface touch, and are assembled with lower snap ring and are limited in ring-type buckle bottom; The bottle cap roof, the ring-type buckle, the hydrophobic oleophobic film consists of a bottle cap air cavity, air can enter or discharge bottle cap air cavity by built-in air extractor vent, air and then enter bottle by the hydrophobic oleophobic film, the interior gas that produces of bottle can be discharged in the bottle cap air cavity and progressive passing through outside the built-in air extractor vent discharge bottle cap by the hydrophobic oleophobic film, and water or oil in the bottle can not leak into outside the hydrophobic oleophobic film, because the aperture of hydrophobic oleophobic film only allows the air turnover, dust, moisture, bacterium and grease can not be by hydrophobic oleophobic film turnover bottles, guaranteed that the content sealing persistence in the bottle is good, water-tight oil tight, do not advance dust and bacterium, also guaranteed the equilibrium of pressure that bottle is inside and outside, made the bottle not be subjected to variation of ambient temperature and cause distortion.
The diameter of described hydrophobic oleophobic film is greater than the diameter of ring-type buckle, and the diameter of hydrophobic oleophobic film is less than the diameter of body of the bottle lid bottle cap mouth.
Described body of the bottle lid madial wall is provided with negative thread, in order to screw togather with the external thread of bottleneck of bottle.
Bottle cap inner roof wall between described body of the bottle lid madial wall and the ring-type buckle lateral wall is provided with the annular seal pad, with the leak tightness of further reinforcement body of the bottle lid and bottle bottleneck.
Bottle cap adopts this structure setting, has solved the drawback of prior art, and following benefit is comprehensively arranged:
Bottle cap is ventilative to have solved that bottle expands with heat and contract with cold and the problem of being out of shape;
Air-permeable layer is surrounded by body of the bottle lid, is positioned at bottle cap inside, prevents contamination by dust;
The air-permeable layer material has the hydrophobic oleophobic performance, and airing function is not because water oil stops up forfeiture;
Material therefor is the used for packing foods material, and safety is secure.
It is good to the utlity model has the sealing persistence, and dust and bacterium are not advanced in water-tight leakage of oil, and the characteristics that can breathe freely.

Fig. 3 is the use state reference map that the utility model is used in bottle.
The specific embodiment
Referring to Fig. 1～shown in Figure 3, a kind of Bottle cap structure comprises body of the bottle lid 1; Described body of the bottle lid 1 inner roof wall is equipped with ring-type buckle 11 downwards, two built-in air extractor vents 12 inwardly are equipped with in madial wall position near described body of the bottle lid 1 inner roof wall, this built-in air extractor vent 12 passes ring-type buckle 11 inwalls and is based in the ring-type buckle inwall, one hydrophobic oleophobic film 2 touches with ring-type buckle 11 lower surfaces, and is assembled with lower snap ring 3 and is limited in ring-type buckle 11 bottoms.
The diameter of described hydrophobic oleophobic film 2 is greater than the diameter of ring-type buckle 11, and the diameter of hydrophobic oleophobic film 2 is less than the diameter of body of the bottle lid 1 bottle cap mouth.
Described body of the bottle lid 1 madial wall is provided with negative thread 13.
Bottle cap inner roof wall between described body of the bottle lid 1 madial wall and ring-type buckle 11 lateral walls is provided with annular seal pad 4.
As mentioned above; the utility model relates to a kind of Bottle cap structure; described embodiment and figure; it is preferably implementation result of the utility model; be not to be confined to the utility model; approximate or the identical person such as structure every and of the present utility model, feature all should belong to the scope that the utility model is protected.
