Abstract
The invention discloses a bottle plug. The bottle plug comprises a base and a drum-shaped portion which is arranged on the base through a connection portion, the external diameter of the connection portion is smaller than the maximum external diameter of the drum-shaped portion, a first cavity is formed in the drum-shaped portion, a second cavity is formed in the connection portion, a through hole is formed in the base, and the first cavity, the second cavity and the through hole are communicated. The middle of the bottle plug is small, the two ends of the bottle plug are large, so that after the bottle plug is inserted in a bottle opening, the bottle opening can be sealed firmly, and sealing performance is good; meanwhile, because the first cavity is formed in the drum-shaped portion, the second cavity is formed in the connection portion, the through hole is formed in the base, and the first cavity, the second cavity and the through hole are communicated, when the bottle plug needs to be pulled out, the base is pulled forcefully, the drum-shaped portion is deformed, the size of the first cavity becomes smaller, reduced air in the first cavity is exhausted through the second cavity and the through hole, and the bottle plug can be pulled out. The bottle plug is good in sealing performance and convenient to use.
Description
Technical field
The present invention relates to a kind of improvement of bottle stopper, a kind of good airproof performance particularly, bottle stopper easy to use.
Background technology
In prior art, common bottle stopper, as the bottle stopper that thermos flask is used, comprises bottle stopper body; Described bottle stopper body is turbination; Described bottle stopper body generally adopts wood materials to make; Re-use in process, find that sometimes bottle stopper deviates from from the bottleneck of thermos flask suddenly, this be thereby thermos flask in pressure excessive, bottle stopper holds can't stand so large pressure, thereby deviates from from the bottleneck of thermos flask; We have researched and developed a kind of good airproof performance for this reason, bottle stopper easy to use.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of good airproof performance, bottle stopper easy to use.
For achieving the above object, the technical solution used in the present invention is: a kind of bottle stopper, comprises base, cydariform portion; Described cydariform portion is arranged on base by connecting portion; The external diameter of described connecting portion is less than cydariform portion maximum outside diameter; In described cydariform portion, be provided with the first cavity; The inside of described connecting portion is provided with the second cavity; On described base, be provided with through hole; Described the first cavity, the second cavity, through hole are communicated with.
Preferably, described cydariform portion's employing nylon or plastics are made.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Middle little ， two of bottle stopper of the present invention is large, thereby after bottle stopper insertion bottleneck, can firmly seal up bottleneck, good seal performance, and simultaneously owing to being provided with the first cavity in cydariform portion, the inside of described connecting portion is provided with the second cavity; On described base, be provided with through hole; Described the first cavity, the second cavity, through hole are communicated with; When pressure in bottle is excessive, cydariform portion can be out of shape, and makes the smaller volume of the first cavity, and the gas reducing in the first cavity is discharged, thereby had certain crushing resistance from the second cavity, through hole; When needs are extracted bottle stopper, pull at base, make the distortion of cydariform portion, make the smaller volume of the first cavity, the gas reducing in the first cavity is discharged from the second cavity, through hole, can realize extracting bottle stopper; Good airproof performance of the present invention, easy to use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The front view that accompanying drawing 1 is bottle stopper of the present invention;
Accompanying drawing 2 is the cutaway view of accompanying drawing 1;
Wherein: 1, base; 2, cydariform portion; 3, connecting portion; 4, the first cavity; 5, the second cavity; 6, through hole.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Middle little ， two of bottle stopper of the present invention is large, thereby after bottle stopper insertion bottleneck, can firmly seal up bottleneck, good seal performance, and simultaneously owing to being provided with the first cavity 4 in cydariform portion 2, the inside of described connecting portion 3 is provided with the second cavity 5; On described base 1, be provided with through hole 6; Described the first cavity 4, the second cavity 5, through hole 6 are communicated with; When pressure in bottle is excessive, cydariform portion 2 can distortion, makes the smaller volume of the first cavity 4, and the gas of the first cavity 4 interior minimizings is discharged, thereby had certain crushing resistance from the second cavity 5, through hole 6; When needs are extracted bottle stopper, pull at base 1, make 2 distortion of cydariform portion, make the smaller volume of the first cavity 4, the gas of the first cavity 4 interior minimizings is discharged from the second cavity 5, through hole 6, can realize extracting bottle stopper; Good airproof performance of the present invention, easy to use.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. a bottle stopper, comprises base, cydariform portion; It is characterized in that: described cydariform portion is arranged on base by connecting portion; The external diameter of described connecting portion is less than cydariform portion maximum outside diameter; In described cydariform portion, be provided with the first cavity; The inside of described connecting portion is provided with the second cavity; On described base, be provided with through hole; Described the first cavity, the second cavity, through hole are communicated with.
