Abstract

The utility model provides a vacuum organ type bottle, which comprises main components including a bottle body, an external bottle cap, a bottom cover, an inner container, a bent nozzle, an internal bottle cap, a middle joint, a pump body and the like. The vacuum organ type bottle is structurally characterized in that the inner container is sleeved inside the bottle body and is a spiral telescopic structure, and an outer opening of the inner container externally extends to an outer opening of the bottle body. Through two structural characteristics and assembly procedures including that the outer edge of the pump body is pressed and the middle joint is in spinning fixation with the bottle body, the inner container is closely jointed with the bottle body and the pump body, an original piston body inside the bottle body is removed, and the telescopic threaded flexible plastic inner container is additionally arranged inside the bottle body. When the liquid dispenser is pressed by external force to increase pressure in the bottle body, pressure inside the inner container is identical to that of external air through a form of upwards contracting the inner container.

Description

A kind of vacuum organ bottle

Technical field

The utility model belongs to daily cosmetics and washes and protect articles for use container manufacturing field, relates generally to a kind of vacuum lotion pump of special inner-tube structure.

Background technology

Protect in the container of articles for use field with washing at daily cosmetics, the liquid distributor of piston pump body structure form is the most common, all is by the curved mouth of pressed by external force usually, makes piston push air in the pump housing downwards, pump housing inner air pressure is increased, and liquid sucks from container and discharges from curved mouth.Different according to purposes, the liquid distributor of piston pump body structure form is divided into common and non-common two kinds of versions, the medium-sized piston pump housing is provided with pore, be used for after pushing piston at curved mouth and pump housing internal pressure is increased and sucking liquid, in the piston lifting process extraneous air is sucked in the container, make container inner air pressure and container keep balance outward, up to the present this technology is to use the most general, the non-medium-sized piston pump housing is not provided with pore, compare with the coventional type piston pump housing, it is characterized in that being equipped with in the bottle piston body, the bottom of bottle has pore, and effect is when the bottle internal pressure increases, and extraneous air can make the bottle inner carrier upwards boost, bottle interior space is reduced with the minimizing of liquid, inside and outside pressure is equated.The structure of the non-medium-sized piston pump housing is as version ripe in the prior art, and the field of its use just constantly enlarges, but because it will increase these parts of piston body in the bottle, and the cost cost increases, the manufacturing process difficulty also increases much.

The utility model content

The purpose of this utility model provides the non-coventional type piston pump of a kind of improved type body structure, cancelled the piston body in original bottle, increased the interior scalable spiral lamination nonrigid plastic inner bag of bottle as bottle, when the pressed by external force liquid distributor increases the bottle internal pressure, by upwards shrinking the mode of inner bag, inner bag internal pressure and external air pressure are maintained an equal level.

The technical scheme of the utility model technical solution problem is such, a kind of vacuum organ bottle, by major parts such as body, outer valve protection cap, bottom, inner bag, curved mouth, interior valve protection cap, middle joint and the pump housings, its architectural feature is that inner bag is sheathed in the body, inner bag is the screw type Collapsible structure, its collar extension overhanging with the body collar extension, compress and middle joint and body spinning are fixed this two architectural features and assembly process by limit, pump housing outer, make inner bag engage airtight with body, the pump housing.

In the described pump body structure, piston rod is positioned at pump housing fluid passage top and is used to push piston and fluid passage, piston rod position hollow structure, its outer ring medium position is sheathed will supporting pad, be used for the integrated support of piston mechanism and the aeroseal of pump housing cavity, upper spring is sheathed on the piston rod, the upper spring bottom is a piston body, piston body also is sheathed on the piston rod, bar is positioned at piston rod inside in the spring piston, is used for liquid drainage and support piston body, and underpart of the piston rod is a lower spring, the lower spring bottom is a water diversion disk, and its underpart is a hoodle.

The utility model is not protected as claim pump body structure, and its structure only need meet the principle of work of vacuum pump liquid distributing box, does not carry out replenish air in the time of promptly to the imbibition of liquid place bottle inherence.

Joint has negative thread and body outside thread in described, and both fix by helicitic texture, and interior bottle hair is sheathed to be fixed on the middle joint.

The inboard lower circumference of valve protection cap is distributed with one section latch symmetrically in described, engages with the latch groove that distributes on the middle joint.

Described curved mouth is positioned at the piston rod upper position, and socket is fixed with it.

Described bottom is positioned at the body bottom, and bottom is provided with some pores, so identical with the external world with the body internal pressure.

Compared with prior art, advantage of the present utility model is: simple and practical, parts are few, and are with low cost, and assembling easily, and is easy to use.

The specific embodiment

Engaging the drawings and specific embodiments below further is described the utility model.

Referring to Fig. 1, a kind of vacuum organ bottle described in the utility model, comprise major parts such as body, outer valve protection cap, bottom, inner bag, curved mouth, interior valve protection cap, middle joint and the pump housing, its architectural feature is that inner bag is sheathed in the body, inner bag is the screw type Collapsible structure, its collar extension overhanging with the body collar extension, compress and middle joint and body spinning are fixed two architectural features and assembly process by limit, pump housing outer, make inner bag engage airtight with body, the pump housing.In the described pump body structure, piston rod is positioned at pump housing fluid passage top and is used to push piston and fluid passage, piston rod position hollow structure, its outer ring medium position is sheathed will supporting pad, be used for the integrated support of piston mechanism and the aeroseal of pump housing cavity, upper spring is sheathed on the piston rod, the upper spring bottom is a piston body, piston body also is sheathed on the piston rod, bar is positioned at piston rod inside in the spring piston, is used for liquid drainage and support piston body, and underpart of the piston rod is a lower spring, the lower spring bottom is a water diversion disk, and its underpart is a hoodle.The utility model is not protected as claim pump body structure, and its structure only need meet the principle of work of vacuum pump liquid distributing box, does not carry out replenish air in the time of promptly to the imbibition of liquid place bottle inherence.

Principle of work: referring to Fig. 1, curved mouth (5) presses down with external force to be pushed, piston rod (9.1) moves downward thereupon, make piston body (9) conduct to the pump housing (8) lower edges position, gas in the compression pump housing, at this moment, liquid is owing to the air pressure in the pump housing (8) makes progress by the pump housing (8) inner chamber bottom hoodle (14) through lower spring (12) lower part water pond (13) in the inner bag (4), in piston in bar (9.2) the sucker bar (9.1), liquid is discharged outside the bottle through curved mouth (5) more again.When not pushing piston rod (3), the air pressure of itself makes hoodle (14) and the pump housing (8) bottom tight engagement in the utility model middle pump body (8), prevents the unexpected outflow of liquid in containers.Extraneous air flows in the body (1) by pore (3.1) in the bottom (3), along with constantly pushing of curved mouth (5), the amount of liquid in the inner bag (4) reduces gradually, makes upwards lifting of inner bag (4), reduce its this province volume, body (1) inner air pressure is equated with extraneous.
