Abstract

The utility model relates to a leak-proof thermos bottle cork which is composed of a bottle cork cover (1), a bottle cork body (2), a heat insulating layer (3) and a sealing ring (4) connected to the bottle cork body. The utility model overcomes the defects of poor hearting preserving performance, air leakage and water leakage of a common thermos bottle cork and the defect of insalubrity because the bottle cork is easy to drop when the thermos bottle is lifted horizontally. The utility model has the advantages of simple structure, extensive material source and easy manufacture.

Description

Anti-leak thermos bottle cork

The utility model relates to a kind of plug for vacuum bottle commonly used, particularly a kind of leakproof plug for vacuum bottle.

Bottle stopper majority now commonly used is made with cork, just the time spent is because bottleneck loses the garden, tightly do not cause gas leakage, to leak and reduced heat-insulating property and make the bottle stopper perisporium fit, to use the damaged aluminium lid of yarn infantees of a specified duration to come off, it is very unhygienic to have tied one deck dirt on the cork, the minority Plastic bottle plug is also arranged on the market, and it is not tight to fit behind the lid that causes because of the thin light weight of wall and because of the bottleneck garden of losing yet, more than two kinds of bottle stoppers all exist heat insulating ability poor, gas leakage is leaked, the horizontal shortcoming of carrying plug.

The purpose of this utility model, the leakproof plug for vacuum bottle of a kind of more practical health that designs in order to overcome above-mentioned shortcoming exactly.Owing to be provided with the shortcoming that a sealing ring has overcome bottleneck mistake garden in this novel bottle stopper bottom, sealing ring and bottleneck inwall are in the state And that closely cooperates all the time during use certain tightness, the advantage of reached air tight, water-tight, not falling plug, in this cock body, be provided with thermal insulation layer, strengthened heat-insulating property.It can determine size according to the requirement of concrete insulating product, makes it to be applicable to various cold, warm vacuum flask, because it selects the non-toxic plastic manufacturing for use, therefore heat preservation food is not had infringement, and health is attractive in appearance.

The utility model is achieved in that the sealing ring (4) that it has bottle stopper (1), Bottle stopper body (2), thermal insulation layer (3) and Bottle stopper body (2) bottom in succession forms this novel anti-leakage plug for vacuum bottle.

The utility model solved that bottle stopper commonly used cooperates imprecision with the insulation bottleneck and the gas leakage that causes, leak, heat insulating ability is poor, unhygienic, bottle stopper easily falls uneasy congruent shortcoming, this new structure is simple, easily manufactured, need only Second Mate's injection mould and the mold of one pair of bubble, use general plastic processing technology just can produce.

Fig. 1 is an orthogonal view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Wherein (1) is that bottle stopper, (2) are sealing ring for Bottle stopper body, (3) for thermal insulation layer, (4).

Leakproof plug for vacuum bottle as shown, when it is covered vacuum flask, at first sealing ring (4) is under the effect of bottleneck propulsive thrust, cause that the strain contraction slips into bottleneck And and touch the downward slippage of mouthful wall, till Bottle stopper body (2) and bottle mouth wall touch, at this moment bottle stopper and bottleneck are in dual fit-state, therefore can not leak, simultaneously because the back tension effect of sealing ring (4), the unsafe factor that has prevented bottle stopper from coming off and caused, the utility model belongs to plastic products, health, easily wash, durable, the pure and fresh bright-coloured And of color can match covering some patterns of plasticising and vacuum flask, and coordination more seems, attractive in appearance.Its alternative cork commonly used and common plastics plug, the heat-insulating property of raising insulating product makes it more perfect.

Claims

1, a kind of leakproof plug for vacuum bottle is characterized in that it is made up of bottle stopper (1), Bottle stopper body (2), thermal insulation layer (3) and sealing ring (4), and Bottle stopper body (2) bottom has in a sealing ring (4) and the Bottle stopper body (2) and is placed with thermal insulation layer (3), and outer wall is the awl cydariform.
