Description
Technical field
The utility model relates to container, specifically a kind of Negative pressure type automatic seal silica gel cover and use the automatic-sealed tank of this lid.
Background technology
Sealable tank is all by arranging corresponding helicitic texture with screwing hermetic on tank body and lid usually, and such structure too tradition and use trouble, needs further to improve with easy for people to use.
Summary of the invention
In order to solve the problem, the utility model provides a kind of silica gel cover of Negative pressure type automatic seal and uses the automatic-sealed tank of this lid.
The technical scheme that the utility model adopts is: a kind of silica gel cover of Negative pressure type automatic seal, it is characterized in that, lid comprises sealing capping, sealing capping edge is provided with the seal ring of upwards flare or introversion downwards, and protruding exhaust button is provided with on sealing capping, this exhaust button is hollow form under shed; Described seal ring, exhaust button and sealing capping are the integrative-structure be made up of silica gel.
A kind of automatic-sealed tank, comprises the tank body of opening upwards, it is characterized in that, also comprise above-mentioned silica gel cover; When silica gel cover covers on tank body, the seal ring of silica gel cover is attached to tank body opening inwall.
A kind of automatic-sealed tank, comprises the tank body of opening upwards, it is characterized in that, also comprise above-mentioned silica gel cover, the seal ring of described tank body opening shape corresponding silica gel lid, in upwards flare shape; When silica gel cover covers on tank body, the seal ring of silica gel cover is attached to tank body opening inwall.
Described sealing capping can be platform-like or arc surfaced.
When silica gel cover of the present utility model uses, only need by under its seal ring corresponding sealable tank tank body vent cover, the air in tank body will be extruded outside its seal ring by lid, automatically forms negative pressure thus reaches the effect of sealing.When taking out lid, then pinch exhaust button with hand, the space in compression tank body, the air pressure in tank body is increased because volume reduces, thus offsets the bar pressure outside tank body, silica gel cover can be opened easily.In order to strengthen the sealing effectiveness of silica gel cover, tank body opening shape can be designed to upwards flare shape, to coordinate the seal ring of silica gel cover, when making under lid lid, the air in tank body is more easily extruded, and the negative pressure formed is stronger, seals tightr.
Vibrational power flow of the present utility model is simple and practical, good sealing effect, uses and also facilitates, fully meet the user demand of people.
