Abstract

The utility model relates to a foam bottle, which solves the problems of that the vessel interior must be communicated with the atmosphere which results in the volatilization of substances in the vessel and affects the using effect of the substances in the bottle toward the existing daily chemical vessel. The utility model comprises a pressing head, a piston pump and a bottle body, characterized in that: a sliding plug, the outer diameter of which is matched with the inner diameter of the bottle body, can slide in the bottle body; a base is arranged at the bottom of the bottle body and an opening is arranged on the base for balancing the atmospheric pressure.

Description

Foam bottle

Technical field:

The utility model relates to a kind of container, particularly a kind of liquid package container.

Technical background:

The packing container of existing liquid daily-use chemical industry such as shampoo, shower cream etc. mostly is to establish the piston pump of a band suction pipe at an upper portion thereof and stretch in the container suction pipe with the liquid sucking-off in the container, the inside of this packing container must be communicated with the pressure inside and outside the equalizing reservoir with the atmosphere in the external world, otherwise can be because of the inwardly shrinkage distortion of in-to-in negative pressure with regard to can not inhaling liquid or container; Its shortcoming is to cause the interior volatilization as materials such as spices of container easily, has influenced the result of use of product.

Summary of the invention:

Technical matters, the purpose of this utility model just provides a kind of Foam bottle without suction pipe, it solved exist in the existing daily-use chemical industry container because of internal tank must communicate with atmosphere cause material in the container volatile, influenced the problem of the result of use of material in the bottle.

Technical scheme:

The purpose of this utility model is achieved in that a kind of Foam bottle, comprises head, piston pump, bottle; It is characterized in that in bottle, being provided with the sliding plug that an external diameter and bottle internal diameter match and can slide in bottle, the bottle space carrying liquid raw material between the sliding plug and the pump housing.

Described Foam bottle, its feature also are to be provided with base at bottle body bottom, have the opening of equilibrium air pressure on the base.

Beneficial effect, owing to adopted technical scheme described in the utility model, when being positioned at the piston pump imbibition on Foam bottle top, owing to produce negative pressure in the bottle, so the sliding plug that will be positioned at bottle is simultaneously inhaled and is made sliding plug upward movement till bottle liquid is sucked to bottle, bottle inside that is to say that Foam bottle described in the utility model is the effect that reaches equilibrium air pressure with effective volume in the decreased locomotion bottle of sliding plug, so need not communicate with the external world; Thereby avoided a bottle interior material to evaporate in the atmosphere, guaranteed that the result of use of the interior material of bottle also can prolong the effective life of bottle interior material.

Description of drawings:

Accompanying drawing is the cut-away view of an embodiment of Foam bottle described in the utility model.

Drawing explanation: 1-cover of dust, 2-head, 3-spring, 4-piston, 5-locking closure, 6-principal post, the 7-pump housing, 8-water shutoff pad, 9-bottle, the sliding plug of 10-, 11-base, 12-opening.

The specific embodiment:

As seen, described Foam bottle comprises head 2, piston pump, bottle 9 from accompanying drawing; Wherein piston pump is made up of spring 3, piston 4, locking closure 5, principal post 6, the pump housing 7, water shutoff pad 8, and water shutoff pad 8 constitutes a check valve with the opening (not marking among the figure) of the pump housing 7 bottoms; In cylindrical bottle 9, be provided with the sliding plug 10 that an external diameter and bottle 9 internal diameters match, carrying liquid raw material in the bottle 9 of sliding 7 of the plug 10 and the pump housings; Be provided with base 11 in bottle 9 bottoms, have the opening 12 of equilibrium air pressure on the base 11.

Its principle of work is when being positioned at the piston pump imbibition on Foam bottle top, owing to produce negative pressure in the bottle 9, the sliding plug 10 that will be positioned at bottle 9 is simultaneously inhaled and made sliding plug 10 upward movements to bottle 9, reduces a bottle interior effective volume, balance the air pressure inside of bottle 9.

Claims

1, a kind of Foam bottle comprises head (2), piston pump, bottle (9), it is characterized in that: be provided with the sliding plug (10) that an external diameter and bottle (9) internal diameter match and can slide in bottle (9) in bottle (9).

2, Foam bottle according to claim 1 is characterized in that: be provided with base (11) in bottle (9) bottom, have the opening (12) of equilibrium air pressure on the base (11).
