Abstract

An anti-jump thermos bottle plug, comprising a cork stopper, a small ball body, and an upper casing cover. A cone shaped groove with bottom surface upward is equipped on the upper part of the cork stopper, a through hole is equipped between the cone tip part of the cone shaped groove and the lower end surface of the cork stopper, and the small ball body is placed on the slope surface of the cone tip part of the cone shaped groove. A plurality of small holes are equipped on the casing cover, and the upper casing cover is located on the cork stopper. A plurality of small holes opposite to the cone shaped groove on the upper part of the cork stopper are equipped on the upper casing cover. The conception of the utility model is felicitous, the structure is simple, the manufacturing is as simple as the commonly adopted thermos bottle plugs, without extra material. The cost is low, the operation is convenient, the heat preservation effect is good, the use is secure, and the practicability of the anti-jump thermos bottle plug is strong, being suitable for household use.

Description

Anti-jump thermos flask plug

Technical field

The utility model relates to a kind of thermos flask stopper, concrete is anti-jump thermos flask plug.

Background technology

There is so common issue with in the thermos flask of family's use now, be about to that boiling water is irritated in the bottle but also less than the time, because of the increase in temperature in the kettle, steam constantly produces, pressure constantly increases, finally be bound to the stopper of jam-pack is ejected, at this moment where stopper perhaps snaps into, and thermos flask will become the water bottle of uncork.If be exactly can not snap into other place, fall again after promptly the thermos flask plug is upspring and hide bottleneck easily, heat preservation effect also can reduce greatly like this.

Such situation also took place once in a while: for preventing upspringing of thermos flask plug, people down press stopper with strength, inner bag with whole thermos flask when the pressure in the kettle surpasses certain pressure bursts, although this thing odds is very little, must notice that thermos flask thrusts the danger that people may bring.

People wish to have a kind of thermos flask plug that can be incubated and not bounce and normal not have the too thermos flask plug of big difference.

Summary of the invention

The purpose of this utility model is to provide a kind of neither spring in order to solve the problem that the thermos flask plug that generally uses now very easily bounces when thermos flask is not filled boiling water fully, can be incubated again, makes and uses all very easy anti-jump thermos flask plug.

The technical scheme that adopts:

Anti-jump thermos flask plug, comprise cork, spherula, upper shell cover, the top of described cork is provided with a bottom surface at last conical socket, between the lower surface of the cone tip part of conical socket and cork a through hole is set, and spherula is placed on the inclined-plane of conical socket cone tip part.Upper shell cover is provided with a plurality of apertures, and upper shell cover is placed on the last end face of cork.

It is relative with the conical socket on cork top that above-mentioned upper shell cover is provided with a plurality of apertures.

The utility model is skillfully constructed, and is simple in structure, on making with same simple of the thermos flask stopper that generally uses now, additionally materials, cheap, very easy to use, heat insulation effect is good, safe in utilization, the practicality of putting jumping thermos flask plug is very strong, is applicable to that family uses.Need to prove that under the constant prerequisite of general idea, principle can also make some changes or distortion to the utility model, this belongs to protection domain of the present utility model equally.
