Abstract

The utility model relates to a bottle stopper for thermos bottles, in particular to a self-locking bottle stopper capable of releasing steam gas pressure. An inner ring (8) of an outer rubber cylinder (15) is sleeved on a circular groove (21) of an inner column (9). A cavity (23) of the rubber cylinder (15) covers the inner column (9). A V-shaped circular recess (22) of the inner column (9) corresponds to circular protrusions (10) of the rubber cylinder (15). A gas chamber (12) is formed between the V-shaped circular recess (22) of the inner column (9) and the rubber cylinder (15). A hole (17) of the rubber cylinder (15) corresponds to the lower end of a gas passage (14) of the inner column (9). The self-locking bottle stopper has the advantages that the circular protrusions can be tightly connected with an opening of an inner bottle so that the stopper is prevented from leaving the opening of a thermos bottle due to inner high pressure of the inner bottle; and the stopper is capable of automatically releasing the inner high pressure of the inner bottle to avoid burst of the inner bottle.

Description

But a kind of self-locking bottle stopper of released vapour gaseous tension

[technical field]

The utility model relates to a kind of thermal bottle bottle stopper, but especially relates to a kind of self-locking bottle stopper of released vapour gaseous tension.

[background technology]

Known, vacuum bottle uses in a lot of families or unit office space as a kind of container of water temperature protection, and the hot water of packing in the glass liner the inside of vacuum bottle is when pouring out some, form certain space in glass liner, the steam that expands in this time space can make wooden bottle stopper takeoff; At this moment the pressure in the glass liner is greater than barometric pressure, so bottle stopper is kept out the pressure of hot air in the bottle incessantly, causes bottle stopper to takeoff to make the hot water down quench in the glass liner; The bottle stopper of commercially available vacuum bottle is vegetable cork, big up and small down taper shape, the bottleneck position of vacuum bottle glass liner is circular, make that the bottleneck of vacuum bottle is that line contacts with the contact surface of bottle stopper, the bottleneck of some relatively poor vacuum bottle glass liner of doing manual work is non-circular structure, in being subjected to bottle, do not have insulation effect during heat air pressure especially, when using the bottle stopper of vegetable cork, need firmly press down, in order to make the bottle stopper distortion form the structure of mating with bottleneck, in case " occur slight crack sometimes " when at this moment glass liner exists became uneven to spare, just can cause the glass liner bottle explosion.

[utility model content]

In order to overcome the deficiency in the background technology, but the utility model discloses a kind of self-locking bottle stopper of released vapour gaseous tension, the utility model can form with bottle bag edge by the annular protrusion bar that arranges and be connected comparatively closely, guaranteed that the utility model can not break away from the vacuum bottle bottleneck because of the high pressure in the glass liner, releasing pressure automatically function when the utility model also has hypertonia in the glass liner has guaranteed that glass liner bottle explosion can not occur.
