Abstract
The utility model provides a unidirectional exhausting and pressure reduction plastic bottle inner cover which is arranged on a plastic bottleneck and solves the technical problem that air pressure rises in a bottle body and cannot be released. The unidirectional exhausting and pressure reduction plastic bottle inner cover is characterized in that: the middle part of the inner cover (1) is provided with a unidirectional exhausting device which is formed by arranging an exhaust pipe (2) in the middle of the inner cover; an elastic sealing piece (3) blocks an exhaust pipe upper port part (4); and an exhaust pipe lower port part (5) is communicated with a lower cavity of a plastic bottle. The inner cover can effectively prevent the bottle body from being cracked due to too high air pressure and avoid dangerous accidents, and can prevent the external air from entering the bottle body and polluting foods and guarantee that the foods are healthy.
Description
Technical field
The utility model relates to the food container assembly, specifically is meant the plastic bottle inner cap that is used for splendid attire food.
Background technology
During common plastics container package food, for avoiding in the bottle food spoilage and being subjected to outside contamination, use masking foil sealed bottle body oral area usually, the bottle oral area screws encapsulation with the screw thread enclosing cover.Adopt this technology of masking foil sealed bottle body oral area to have potential safety hazard, when food was contained in this plastic container, temperature was more than 30 degree, the food fermentation can produce a large amount of gases in the bottle in bottle, cause the bottle internal gas pressure to raise, as untimely release bottle internal gas pressure, the explosion of plastic bottle tank capacity.Thing form is sprayed in the bottle explosion, and light contaminated environment then is heavy then the personnel that may cause wound accident, gives to produce and sell when management and client use to have many hidden dangers, a kind of product that can address the above problem of urgent need on the market.
Summary of the invention
The purpose of this utility model is that a kind of unidirectional exhaust decompression plastic bottle inner cap that is installed on the plastic bottle oral area will be provided, and solves the technical matters that the bottle internal gas pressure raises and can't discharge.
The technical solution of the utility model is to realize like this, unidirectional exhaust decompression plastic bottle inner cap, comprise inner cap, it is characterized in that: establish a unidirectional exhaust gear at inner cap 1 middle part, described unidirectional exhaust gear is to establish a freeing pipe 2 at the inner cap middle part, one elastic sealing element 3 is blocked freeing pipe upper oral part 4, the cavity of resorption of freeing pipe infraoral 5 UNICOM's plastic bottles.
Described freeing pipe 2 is a Coupling with elastic sealing element 3, and elastic sealing element 3 is socketed in freeing pipe 2 tops.
Described freeing pipe 2 and inner cap 1 global formation, freeing pipe 2 interior cover be shaped as the exhaust stake.
Compare with masking foil sealed plastic mouth cylindrical part with prior art, the utlity model has tangible technique effect.
1, inner cap of the present utility model can prevent effectively that bottle is because of the too high explosion of air pressure.Owing to be provided with unidirectional exhaust gear interior covering, can with the high pressure gas in the bottle by emission by exhaust pipe in the cavity on bottle top, and extraneous gas can not enter in the bottle, can guarantee food hygiene, and is not perishable.
2, with inner cap and exhaust stake global formation, design science is reasonable, low cost of manufacture.Set up an exhaust stake and an elastic seal cartridge when making inner cap, elastic seal cartridge is socketed in the exhaust stake, can realize the self-bleeding decompression.
3, design is ingenious rationally, and is very practical.Set the thickness of elastic seal cartridge, to meet pressure and the interior needed pressure requirement of food of bottle that plastic bottle can bear.Owing to be provided with elastic seal cartridge, gas can only be washed elastic seal cartridge from inside to outside open and overflow, and can not be back in the bottle, has guaranteed that food is not contaminated, not perishable in the bottle.Can prevent that bottle from increasing explosion because of interior pressure, can guarantee food clean hygiene in the bottle again.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Unidirectional exhaust decompression plastic bottle inner cap is characterized in that establishing a unidirectional exhaust gear at inner cap 1 middle part, and described unidirectional exhaust gear is to establish a freeing pipe 2 at inner cap 1 middle part, freeing pipe 2 interior cover be shaped as the exhaust stake, described freeing pipe 2 and inner cap 1 global formation.Described elastic sealing element 3 is a flexible rubber hose, and described exhaust stake and flexible rubber hose socket utilize flexible rubber hose sealing freeing pipe 2 upper oral parts 4, the cavity of resorption of freeing pipe infraoral 5 UNICOM's plastic bottles.When the bottle internal gas pressure raise, high pressure gas are broken through flexible rubber hose by freeing pipe 2 pressure flowed to the bottle top.
