The inner container 20 is disposed within the bottle 11 and includes a flexible tube 21. The flexible tube 21 is longitudinally extendable and compressible and has a chamber 21 1. The chamber 211 is formed in the flexible tube 21 and is filled with a cosmetic liquid. The airless dispensing pump 30 is mounted on the bottle 11 to seal the chamber 211 of the flexible tube 21. The sealed chamber 211 of the flexible tube 21 prohibits air from entering and prevents leakage of the cosmetic liquid. As such, it may maintain sterility or quality of the product to be dispensed. The chamber 211 can thus be filled with either a low viscosity liquid or a high viscosity liquid.
Description
APPARATUS FOR CONTAINING AND DISPENSING FLUIDS UNDER
PRE SSURIE
1. Field of the Invention
The present invention relates to an apparatus for containing and dispensing fluids under pressure, and more particularly to an apparatus for containing and dispensing fluids under pressure to prevent air from flowing into a chamber filled with a liquid.
2. Description of the Related Art
Apparatuses for containing and dispensing fluids under pressure are commonly filled with a specific cosmetic liquid for different uses, for instance, liquid foundation, milky lotion, and the like.
With reference to FIG. 5, a conventional apparatus for containing and dispensing fluids under pressure comprises an acrylic outer container 40 and an airless dispensing puirip 50. The outer container 40 includes a bottle 41, a piston 42 and a chamber 43. The bottle 41 has a top wall, a bottom wall, an inner surface and at least one vent hole 411. The at least one vent hole 411 is formed in the bottom wall of the bottle 41. The piston 42 is movable in the bottle 41 and has an outer surface slidably abutting the inner surface of the bottle 41. The chamber 43 is formed between the top wall of the bottle 41 and the piston 42 and is filled with a cosmetic liquid. The airless dispensing pump is mounted on the bottle 41 and includes a spout 51, a dip tube 52 and a check valve. The dip tube 52 extends into the chamber 43. In use, the spout 51 is depressed to allow the cosmetic liquid to flow from the chamber 43 into the dip tube 52 and the check valve and then out of the spout 51. Because the check valve prevents the ambient air from being forced into the chamber 43, the ambient pressure pushes the piston 42 to reduce the volume of the chamber 43 so as to equalize the pressure within the chamber 43 and the ambient pressure when the cosmetic liquid flows out of the chamber 43.
1-lowever, the piston 42 must be movable relative to the bottle 41 such that the outer surface of the piston 42 cannot tightly and sealingly abut the inner surface of the bottle 41. The ambient air may enter the unsealed chamber 43 through the gap between the outer surface of the piston 42 and the inner surface of the bottle 41 and thus bacteria may enter the chamber 43 with the air to contaminate the cosmetic liquid. In order to prevent the growth of bacteria in the cosmetic liquid, the cosnietic liquid must contain antioxidants such as ethylenediaminetetraacetic acid (EDTA), butyl hydroxy toluene (BHT) or butylated hydroxy anisole (BHA), and preservatives such as toluene or formaldehyde. All these antioxidants and preservatives cause allergic reactions and cancer. In addition, the chamber 43 can only be filled with a high viscosity liquid containing ernulsifiers, which also cause allergic reactions. A low viscosity liquid may leak out through the gap between the outer surface of the piston 42 and the inner surface of the bottle 41 while filling the chamber 43.
Furthermore, the chamber 43 cannot be filled with alcohol, essential oil or a high acid or high alkali solution, and the outer container 40 caimot be disinfected by water at a temperature higher than 50° C because the outer container 40 is made of acrylic.
The main object of the present invention is to provide an apparatus for containing and dispensing fluids under pressure to prevent air from flowing into a chamber filled with a liquid.
To achieve the foregoing objective, the apparatus for containing and dispensing fluids under pressure in accordance with tile present invention comprises an outer container, an inner container and an airless dispensing pump.
The outer container includes a bottle having a body. The body has an open top and an open bottom. The inner container is disposed within the bottle and includes a flexible tube. The flexible tube is longitudinally extendable and compressible and has an open top, a closed bottom and a chamber. The open top of the flexible tube is seahngly connected to the open top of the body of the bottle. The chamber is formed in the flexible tube and is filled with a cosmetic liquid. The airless dispensing pump is mounted on the open top of the body of the bottie to seal the chamber of the flexibhe tube and includes a dip tube. The dip tube extends into the chamber of the flexible tube through the open top of the flexible tube. The sealed chamber of the flexible tube prohibits air from entering and prevents leakage of the cosmetic iiquid. The chamber can thus be filled with either a low viscosity liquid or a high viscosity liquid.
IN THE DRAWINGS: FIG. I is a perspective view of an apparatus for containing and dispensing fluids under pressure in accordance with the present invention; FIG. 2 is an exploded perspective view of the apparatus for containing and dispensing fluids under pressure in Fig. 1; FIG. 3 is a cross-sectional side view of the apparatus for containing and dispensing fluids under pressure in Fig. 1; FIG. 4 is an operational cross-sectional side view of the apparatus for containing and dispensing fluids under pressure in Fig. 1 showing an actuated state; and FIG. 5 is a side view in partial section of a conventional apparatus for containing and dispensing fluids under pressure in accordance with the prior art.
With reference to FIGS. 1 to 3, an apparatus for containing and dispensing fluids under pressure in accordance with the present invention comprises an acrylic outer container 10, a nylon inner container 20 and an airless dispensing pump 30.
The outer container 10 includes a bottle 11 and a bottom cover 12. The bottle 11 has a cylinder body Ill, a neck 112 and a coimecting wall 113. The body Ill has an outer diameter, an open top and an open bottom. The neck 112 extends from the open top of the body 111, is provided with an external thread 114 and has an outer diameter less than the outer diameter of the body 111. The connecting wall 113 extends from the open bottom of the body Ill. The bottom cover 12 covers the connecting wall 113 of the bottle 11 and has a bottom wall and at least one vent hole 121. The at least one vent hole 121 is formed in the bottom wall of the bottom cover 12.
The inner container 20 is disposed within the bottle 11 and includes a flexible tube 21 and a connecting tube 22. The flexible tube 21 is longitudinally extendaHe and compressible and has an outer diameter, an open top, a closed bottom and a chamber 211. The flexible tube 21 is typically a bellows having a plurality of pleats. The chamber 211 is formed in the flexible tube 21 and is filled with a cosmetic liquid. The connecting tube 22 extends from the open top of the flexible tube 21 and has an outer diameter less than the outer diameter of the flexible tube 2 1. The connecting tube 22 is sealingly inserted into the neck 112 of the bottle 11 by heat sealing or by high freqLLency welding. The bottom cover 12 serves to protect the inner container 20 from impact mid to improve the appearance of the outer container 10.
The airless dispensing pump 30 may be conventional, is mounted on the open top of the body 111 of the bottle 11 to seal the chamber 211 of the flexible tube 21 and includes a housing 31, a dip tube 32, a check valve, a spout and a spring 36. The housing 31 is provided with an internal thread 311 screwed on the external thread 114 of the neck 112 of the bottle 11. The dip tube 32 is disposed within the housing 3 1, extends into the chamber 211 of the flexib'e tube 21 through the connecting tube 22 and has a plug 321 mounted in a bottom portion of the dip tube 32. The check valve has a conduit 33 and a sleeve 34. The conduit 33 is movable in the dip tube 32 and has an open top, a bottom block 331, an annular wall and a plurality of orifices 332. The bottom block 331 is able to abut the plug 321. The orifices 332 are formed through the airnular wall of the conduit 33. The sleeve 34 is movable on the conduit 33 and is able to close the orifices 332. The spout 35 is mounted on the open top of the conduit 33 and has an opening 351. The spring 36 is disposed between the housing 31 and the spout 35.
With reference to FIG. 4, in use, the spout 35 is depressed against the force of the spring 36 to move the conduit 33 so as to open the orifices 332 of the conduit 33. The cosmetic liquid can thus flow from the chamber 211 into the dip tube 32 and the conduit 33 and then out of the opening 351 of the spout 35. The spout 35 is then released and the spring 36 returns the spout 35 and the conduit 33 to their original positions, thereby closing the orifices 332. Because the check valve prevents the ambient air from being forced into the chamber 211, the ambient pressure pushes the closed bottom of the flexible tube 21 to reduce the volume of the chamber 211 so as to equalize the pressure within the chamber 211 and the ambient pressure when the cosmetic liquid flows out of the chamber 211.
The sealed chamber 211 prohibits air from entering and prevents leakage of the cosmetic liquid. The chamber 211 can thus be filled with either a low viscosity liquid or a high viscosity liquid. The chamber 211 also can be filled with alcohol, essential oil or a high acid or high alkali solution, and the inner container 20 can be disinfected by water at a temperature not higher than 1000 C because the iimer container 20 is made of nylon.
