Abstract
The utility model relates to a vacuum bottle, which comprises a bottle body, a shoulder bush and a sprayer. A transparent outer cover is arranged outside the bottle body, an outer sleeve is arranged outside the transparent outer cover, a piston is arranged in the bottle body, a fastener is arranged in the shoulder bush, a vacuum pump matched with the piston is arranged in the fastener, an outer cover is arranged outside the sprayer, and an elastic one-way valve is arranged between the vacuum pump and the piston. The vacuum bottle has the advantages that the one-way valve has certain elastic deformation and can be reset automatically, and thereby the problem of poor adaptability for high-concentration liquid or cream is solved. The vacuum bottle made by LLDPE (linear low density polyethylene) materials is non-poisonous, environment-friendly and prevents secondary pollution, production cost is reduced, air impermeability is improved so that loss of spraying capacity of a pump is reduced greatly and performance of the pump is improved.
Description
Technical field
The utility model relates to a kind of cosmetics containers, especially a kind of Dewar bottle.
Background technology
The employed pump head of emulsion skin care item in the market all adopts the spheroid of glass or stainless steel to realize the function of check valve.Its performance of such valve version is unsatisfactory, mainly contains following some deficiency: poor for applicability for high concentration liquid or lotion, have a strong impact on the spray pump performance; Material is stainless steel or glass, and there is secondary pollution in content; Because poor air-tightness causes pump housing suction little, the loss of pump discharge rate is big.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of Dewar bottle of stable performance is provided.
The utility model solves the technical scheme that its technical problem adopts: this Dewar bottle, comprise bottle, shoulder cover, shower nozzle, and wherein bottle is provided with transparent housing outward; Transparent housing is provided with overcoat outward; Be provided with piston in the bottle, be provided with clamp in the shoulder cover, be provided with the vavuum pump that cooperates with piston in the clamp; Shower nozzle is provided with outer cover outward, is provided with the rubber-like check valve sheet between vavuum pump and the piston.
As preferably, said check valve sheet adopts the LLDPE material.
The effect that the utility model is useful is: the one-way cock sheet has certain elastic deformation, has realized self-return, thereby has solved the problem for high concentration liquid or lotion bad adaptability; Adopted the LLDPE material, nontoxic, environmental protection has prevented the appearance of secondary pollution, and has reduced production cost.Improve air-tightness, made the loss of pump discharge rate reduce significantly, improved pump performance.
