Abstract
The utility model provides a pressure-reducing bottle cover, in the center of which a round hole is arranged and a hallow bolt is turned into from the upper part of the hole. The upper two sides of the bolt have horizontal steam holes communicating to the hollow cores. The utility model allows opening the hollow bolt and letting air enter through the steam holes provided that the cover can not be opened due to negative pressure inside the bottle cover.
Description
Affiliated technical field
The utility model relates to a kind of small-sized daily necessities, a kind of specifically bottle cap that reduces pressure.
Background technology
The present thermal bottle that uses and other dress hot water or cold water's vessel, long in standing time, will produce the phenomenon that to open bottle cap, mainly be to have produced negative pressure in the inside and outside bottle that the temperature difference caused of bottle, will easily open bottle cap in case entered air, especially Chang Yong thermal bottle, the easiest generation negative pressure can cause thus that uncork is bad to cause the glass liner explosion.
Summary of the invention
The utility model provides a kind of bottle cap that reduces pressure, and can enter air and open bottle cap under the situation of negative pressure occurring by device set on the bottle cap.
The technical scheme that the utility model adopted is: described bottle cap is characterized in that: the central vertical of bottle cap is provided with a circular hole, and screwing in outside top in the circular hole has a hollow bolt, and the both sides, top of hollow bolt laterally are provided with the steam vent eye that communicates with hollow.
The beneficial effects of the utility model are: occurring under the situation that bottle cap can't open, available bottle opener unclamps the hollow bolt, allows the steam vent eye of its hollow both sides expose bottle cap, begins to allow air enter in the bottle from eyelet.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Among the figure: bottle cap 1 central vertical is established a circular hole 2, screws in hollow bolt 3 in the circular hole 2 outside top, and the steam vent eye 4 that communicates with hollow is laterally established in the both sides, top of hollow bolt 3.
