Description
- The invention relates to a dispensing container provided with a foaming device, comprising: a container body made from flexible material, having a bottom and a neck defining a mouth; a head member fittable to said neck; a dip tube extending from said mouth to short of said bottom and allowing fluids to flow therethrough in an axial direction; and a stopper member, adapted to occupy alternately a closed position and an open position.
- It is frequently required to apply liquids over certain surfaces without the liquid spreading from the particular area where it is applied. To this end, foams generated from the liquid it is desired to apply and a gas are habitually used. Containers containing a liquid and a pressurised propellant gas and which, when a valve operating button is pressed, supply a foam formed by the liquid it is desired to apply and the propellant gas are known. The propellant gas is usually partly liquefied in the pressurised pack. Chlorofluorocarbonated (CFC) products have been frequently used among the propellant gases. These, as has been subsequently shown, represent a serious burden for the environment. Other propellant gases have the drawback of relatively higher costs. Furthermore, the containers are generally not rechargeable so that, once used, they are thrown away, which also represents a relatively high cost and an additional burden for the environment.
- It is an object of the invention to overcome these drawbacks. This object is achieved with a dispensing container provided with a foaming device of the type first mentioned above characterised in that it comprises a dip tube holder attached to said head member and which is provided with: [i] a tubular appendix penetrating in said neck and in which there is attached said dip tube, there being formed between said appendix and said dip tube an axial space suitable for the passage of liquids from said container body; [ii] an inwardly extending crown, having a central opening defining a second cross section, said crown facing said dip tube, with which it limits a transverse communication passage suitable for the passage of liquids from said axial space; [iii] a decompression chamber located immediately downstream of said central opening and defining a first cross section larger than said second cross section; and [iv] at least one transverse mesh, provided with orifices forming the sole passage means, downstream of said decompression chamber.
- A dispensing container provided with a foaming device according to the invention allows the desired amount of foam to be obtained quickly, very cheaply and with a minimal environmental impact by simply squeezing the walls of the flexible material container body. In fact, a dispensing container of this type does not require the use of any special gas, since the gas used in the ambient air. Since the container is not pressurised, the components are very cheap to manufacture. Furthermore, the small number of components required makes the unit even cheaper. The container may be developed as rechargeable, which represents a further saving over the presently known systems and, additionally, both the use of air as propellant gas and the use of rechargeable containers represent a significant reduction of the environmental impact.
- Further advantages and features of the invention will be appreciated from the following description in which there is disclosed a preferred embodiment of the invention without any limiting scope and with reference to the accompanying drawings, in which:
- Figure 1 is an axial sectional view of one embodiment of a dispensing container of the invention, with the stopper member closed.
- Figure 2 is a sectional view similar to the previous Figure, with the stopper member open and arrows showing the gas and liquid flows.
- Figure 3 is a part axial sectional view, on a larger scale, of the neck of the container body and of the foaming device of Figure 2.
- Figure 4 is a part axial sectional view, on a larger scale, of the centre portion of the section of Figure 3.
- Figure 5 is an axial section view of the neck of the container body and of the foaming device, showing the path followed by the foam.
- Figure 6 is a partial axial sectional view of another embodiment of the invention, with a different location of the transverse mesh.
- Figure 7 is a partial axial sectional view of a third embodiment of the invention, with two transverse meshes.
- The dispensing container basically comprises three main members: a container body 1, which is made from flexible material suitable for being deformed by manual squeezing, a
stopper member 2 and a foaming device 3 (Figure 1). The container body 1 defines a bottom 4 and aneck 5 forming a mouth. - The
stopper member 2 covers thefoaming device 3. In the embodiment described and illustrated, it is suitable for being moved axially between a closed position and an open position (Figures 1 and 2). Nevertheless, the invention also comprises other embodiments of the stopper member, such as a threaded connection, pivoting on a hinge and others. - The
stopper member 2 is provided with anorifice 6 through which the foam exits once formed and which also operates as a valve seat. When thestopper member 2 is in the closed position, theorifice 6 has astem 7, fixedly attached to thefoaming device 3, inserted therethrough, closing the passage between the interior of thefoaming device 3 and the outside, whereas when thestopper member 2 is in the open position, theorifice 6 is separated from thestem 7, placing the interior of thefoaming device 3 in communication with the outside. - The
foaming device 3 comprises, in turn, ahead member 8, adip tube 9, adip tube holder 10 and a transverse mesh 11 (Figures 3 and 4). - The
head member 8 is mounted on theneck 5 and has mounted therein thedip tube holder 10. Thedip tube holder 10 is provided with atubular appendix 12 which penetrates axially in the interior of theneck 5. Within thetubular appendix 12 there is mounted thedip tube 9 in such a way as to leave a hollowaxial space 13 between the inner surface of thetubular appendix 12 and the outer surface of thedip tube 9. Thedip tube 9 extends, on the opposite side, towards the interior of the container body 1 towards thebottom 2, stopping short thereof. Thedip tube 9 is hollow and is suitable to allow fluids to flow therethrough in the axial direction. The end of thedip tube holder 10 opposite to thetubular appendix 12 end consists of a generallycylindrical wall 14, defining a first cross section and afree end surface 15. The interior of thecylindrical wall 14 forms adecompression chamber 16, and is attached to thetubular appendix 12 by means of an inwardly extendingcrown 17 having acentral aperture 18 defining a second cross section substantially smaller than the first cross section of thedecompression chamber 16. Thecrown 17 is provided, on thetubular appendix 12 side, withprojections 19 abutting the end of thedip tube 9 which is inserted in thetubular appendix 12 in such a way that there is left ahollow communication passage 20 between thecrown 17 and thedip tube 9 which communicates, on one side, with theaxial space 13 between the inner surface of thetubular appendix 12 and the outer surface of thedip tube 9 and, on the other side, with the open end of thedip tube 9 and with thecentral aperture 18 of thecrown 17. - The
cylindrical wall 14 is provided, at the end opposite to thecrown 17 end, with thetransverse mesh 11, which is mounted on thefree end surface 15 thereof. - The dispensing container operates as follows. The dispensing container is placed with the
foaming device 3 directed downwardly and must be filled with liquid only up to acertain level 21, such that there is a certain amount of air in the container body 1 and also to prevent the liquid from reaching thedip tube 9. When the flexible side walls of the container body 1 are squeezed, an excess pressure is formed in the interior which causes the air to move axially through thedip tube 9 following thearrows 22 and causes the liquid to move through theaxial space 13 as shown by the arrows 23 (Figure 4). The liquid flows through theaxial space 13 andhollow communication passage 20 and is introduced into the air flowing through thedip tube 9 inwardly, i.e. in a direction perpendicular to the direction of the air flow, thereby forming a homogenous aerosol type mixture between the liquid and the air. The mixture flow passes through thecentral aperture 18 of thecrown 17 and into thedecompression chamber 16. At the end of thedecompression chamber 16, the air and liquid mixture flow encounters themesh 11, which serves to generate the foam which, finally, flows through the terminal end of thestopper member 2, round thestem 7 and out through the orifice 6 (Figure 5). - The ratio of the second cross section of the
central aperture 18 of thecrown 17 to the first cross section of thedecompression chamber 16 must be such that while the second cross section of thecentral aperture 18 of thecrown 17 has a size such that the air flow speed is caused to be sufficiently high to form an aerosol, the first cross section of thedecompression chamber 16 is of such a size as to allow a reduction of the air speed to a speed appropriate for the formation of the foam in thetransverse mesh 11. - Figure 6 shows another preferred embodiment of the invention, in which a
transverse mesh 24 is housed in thedecompression chamber 16, being thus lodged between thefree end surface 15 of thecylindrical wall 14 and thecrown 17. Thistransverse mesh 24 is mounted on aring 25, the outside wall of which contacts the inside surface of thecylindrical wall 14. - Figure 7 shows, finally, a further alternative embodiment of the invention having two
transverse meshes ring 25 and housed in thedecompression chamber 16 and the other mounted on thefree end surface 15 of thecylindrical wall 14.
