Definitions

  • This invention relates to improvements in hermetically sealed packages of self-propelling pressure multi-phase liquid compositions equipped with a valve assembly adapted to spray the liquids contained in said packages.
  • the, invention relates to a particular arrangement of the dispensing device in an aerosol pressure container, wherein a portion of the liquid from each of at least two liquid phases is simultaneously released from the container to concomitantly produce a spray of very fine droplets.
  • Aerosol spray dispensers or aerosol containers having an eduction tube through which the container contents exit are widely employed for the purpose of spraying a variety of products, in particular insecticides, bactericides and deodorants.
  • formulations employed comprised an homogeneous phase consisting of the propelling agent, known as propellant (e.g., liquefied gas, such as n-butane, propane, dichlorodifiuoromethane) in which is dissolved the active agent (concentrated insecticide or deodorizing product, for example).
  • propellant e.g., liquefied gas, such as n-butane, propane, dichlorodifiuoromethane
  • active agent concentrated insecticide or deodorizing product, for example.
  • Such corno'sitions are useful due to the fact that the active agent is soluble in all proportions in the liquefied propellant gas. The abrupt vaporization of said propellant upon discharge through the valve when the spray dispenser is actuated produces a fine spray of said active agent
  • a still further object of the invention is to provide a dispensing unit for the aerosol containers of the kind specified, which is easy to manufacture and to adapt onto said containers.
  • the present invention is based on the discovery that, at the moment of utilization of the aerosol container, it was possible by means of a particular arrangement of the dispensing device to produce inside the eduction tube and the valve an intimate mixture of the liquids contained in the pressure can. It is thus possible to effect the fine and simultaneous atomization of both the water and the active agent in an aerosol container containing two liquid phases separated by density, one phase being formed by the water and the other by the active agent dissolved in the liquefied propellant.
  • the aerosol container which contains two immiscible liquid phases of different density, namely an aqueous phase and an organic phase consisting of a liquefied propellant gas in which the active agent is present in the dissolved state, and which container is fitted with a dispensing device consisting of a spray-discharge stopper valve supplied by means of an eduction tube immersed in the liquid and open at the free end thereof, is mainly characterized in that said eduction tube of the dispersing device is provided with a succession of fine perforations extending over a distance of the eduction tube such that a certain number of said perforatitons are immersed in the aqueous phase while other perforations are immersed in the organic phase.
  • the perforations which are formed in the eduction tube have a diameter substantially ranging between about 0.01 mm. and 1.2 mm., a diameter between 0.3 and 1 mm. being generally preferred, and these perforations are disposed over the whole length of the tube.
  • FIG. 1 is a view in diametric cross-section of an aerosol container having a dispensing device designed in accordance with the invention
  • FIG. 2 is an enlarged fragmental cross-section of the valve shown in FIG. 1, said section being taken on the line IIII of FIG. 3, illustrating the valve in closed position;
  • FIG. 3 is a transverse section taken on the line III-III of FIG. 2;
  • FIG. 4 is a similar section taken on the line IV-IV of FIG. 3, but showing the valve in open position;
  • FIG. 5 is a cross-section taken on the line VV of FIG. 2.
  • the improvements which are provided by the present invention are applicable to a container of the aerosol dispenser type for the purpose of spraying an active product, such as deodorant, disinfectant or insecticide.
  • the numeral 1 designates the said container which is closed by a crimped-on cover 2 inside which is mounted the stopper valve 3 of the dispensing device, said valve being joined to an eduction tribe 4 which extends downwards inside the container 1.
  • the eduction tube 4 is of flexible synthetic material and has preferably a length which is slightly greater than the internal depth of the container 1, with the result that said eduction tube takes up a position inside said container in the manner shown in FIG. 1.
  • the stopper valve 3 is of a generally known type, and accordingly comprises (FIGS. 24) a valve housing 5, an annular bulge 6 being formed on the top portion of said housing .and the cover 2 being crimped around said annular bulge, thereby imprisoning a thick flexible sealing disc 7.
  • the bottom portion of the valve housing 5 is provided withan extended portion in the form of a nipple 8 on which is fitting the eduction tube 4.
  • valve housing S There is mounted in the interior of the valve housing S a sliding core 11 which terminates at the base thereof in a boss 12 and has an upwardly extending tubular valve stem 13 over which is fitted a head 14 forming a pushbutton.
  • a spring 19 is fitted around the boss 12 and is applied against radial seating members 21 of the valve housing 5.
  • valve stem 13 and valve core 11 are forced downwardly against the tension of the spring 19 and by this operation the inner margin of the sealing disc 7 is bent downwardly, as shown in FIG. 4, to uncover the passages 16 and thus open communication between the interior of the container and the exterior thereof by way of the eduction tube 4, passage 10, chamber 20, and thence through the opening(s) 16 into passage 17 of the valve stem to and through the discharge orifice 18.
  • the pressure of such vapor phase causes the liquid to flow upwardly through the eduction tube 4 when pressure is applied on the stopper valve 3.
  • the liquid follows the path which has been indicated above and when the liquid gas reaches the orifice 18, it then volatilizes and disperses the active agent in a fine spray.
  • an opening 35 which places into communication the vapor phase which is present above the liquid and the annular space which is formed between the housing 5 and the core 11.
  • the opening (as shown in FIG. 3 and FIG. 4) is thus arranged parallel to the eduction tube 4 relatively to the radial conduits 16.
  • the opening 35 plays the part of a gas intake.
  • the gas-flow which is thus injected on the upstream side of the passages 16 into the liquid to be sprayed substantially improves the quality of the atomization.
  • the pressure container 1 contains a homogeneous liquid phase which is constituted, for example, by an active agent dissolved in a liquefied propellant gas.
  • the eduction tube 4 in FIG. 1 is provided over the entire length thereof with two lines of perforations 31 which are equidistant and in diametrically opposite relation.
  • Such perforations are of very small diameter and can accordingly be formed by means of a needle which is passed through the eduction tube 4 from one side to the other.
  • the diameter of the perforations plays a critical part inasmuch as said diameter is dependent on the volumetric proportions of the two immiscible liquid phases, namely the higher-density phase 32 (water, for example) and the light or lower-density phase 33 (for example, liquefied gas in which an active concentrate is present in the dissolved state).
  • the former components constituting the phase 32 and representing one volume
  • the eduction tube 4 is formed of plastic material (mixture of polyethylene and isobutylene, for example) a certain swelling of the tube takes place, especially when this latter is in contact with the organic phase 33, and has a tendency to contract the perforations. Accordingly, in the case of the example given, the diameter of the perforations 31 must be 0.9 mm. at the time of piercing, this diameter being reduced as a result of swelling action to 0.4 mm. when the eduction tube is immersed in the liquid.
  • plastic material mixture of polyethylene and isobutylene, for example
  • the resulting mixture which reaches the discharge orifice 18 is thus in a suitable state of dispersion and the vaporization of the propellant at the outlet of said orifice results in the discharge of the aqueous phase and the organic concentrate in an atomized spray pattern of very fine droplets.
  • the homogeneous quality of the spray can thus be stated by visual inspection.
  • the present invention accordingly provides a means of dlspensing compositions which correspond, for example, to the following formulations:
  • Insecticide formulation-Insecticide concentrate Percent (Pyrethrum dissolved in petroleum) n-Butane 40 Water 50 Deodorant formulation-Deodorant concentrate:
  • FIGS. 6-11 a variant to the construction described above and shown in FIGS. 1-5 may be resorted to. This variant is illustrated in FIGS. 6-11.
  • the holes or perforations which are formed in said tube ' are freed from the upper liquid phase in increasing number as the level falls within the dispenser-can during utilization.
  • the composition of the dispersion which is discharged from the container is liable to be modified in time due to increased concentration of the gase phase.
  • loss of gas may become appreciable with concomitant adjustment of the propellant liquid phase resulting in alteration of the initial volumetric proportion of the liquid phases.
  • the improvement of the constructions of FIGS. 6-11 are especially characterized in that the eduction tube which extends from the stopper-valve to the bottom of the container is curved in the vicinity of said container bottom and has an extension in the form of an ascending branch, and in that the successive lateral perforations of the eduction tube are formed only in said ascending branch.
  • the eduction tube can be given a U-shape, at least a part of the ascending branch of the U being disposed in a substantially parallel relation to the main branch.
  • the curved eduction tube can either be shaped in the cold state, or in the hot state in a definitive manner or, on the contrary, said tube can be deformed elastically, in which case the ascending branch is retained by means of a fastening member or by the walls of the container.
  • steps are preferably taken to ensure that the upper extremity of the ascending branch of the eduction tube is sealed oif.
  • the eduction tube employed is of the type know as a capillary tube (having an internal diameter ranging between 0.3 mm. and 1.5 mm.) and is provided with one or a number or rows of equidistant perforations.
  • compositions can be employed which contain high proportions of aqueous phase.
  • Such formulations are obviously economically advantageous; such compositions may contain, for example, as much as 75% water.
  • FIGS. 6-11 A number of constructions which illustrate the feature of avoiding gas loss are illustrated in the accompanying drawings for FIGS. 6-11, which have been given solely by way of example without any limitation being implied, and in which:
  • FIG. 6 is a sectional view on an axial plane, showing a first form of embodiment of the aerosol container
  • FIG. 7 is a fragmentary front sectional view on a highly enlarged scale, showing the valve head
  • FIGS. 8, 9 and 10 are views in elevation on a smaller scale showing a number of different forms of embodiment of the eduction tube, the lateral wall of which has been partially broken away;
  • FIG. 11 is a perspective diagram on a large scale showing an alternative form of embodiment of the perforated eduction tube.
  • the reference numeral 1 designates the container of the aerosol dispenser type which is closed by a crimped-on cover 2 inside which is mounted a stopper valve 3, the valve head being designated by the reference 14.
  • the stopper valve 3 is joined to the eduction tube 4 which is fitted over an end-piece 51 which extends downwardly from the valve body 5.
  • the eduction tube 4 has a downwardly extending portion 52, hereinafter referred to as the descending branch, which reaches the vicinity of the base 53 of the aerosol container and which extends beyond an elbow 54 so as to form an upwardly extending portion 55, hereinafter'referred to as the ascending branch.
  • No perforations are formed in either the descending branch 52 or the elbow 54 and only the ascending branch 55 is provided with a succession of lateral perforations 31.
  • the upper terminal portion of the ascending branch 55 is closed by an endwall 56.
  • the eduction tube 4 which assumes the shape of a U is of either rigid or semi-rigid design.
  • the eduction tube can be fabricated of thermoplastic material with a sufficient thickness of wall to ensure that the elbow 54 can be formed by bending of a straight tube without any attendant danger of folding or pinching.
  • a material such as polyethylene is usually very suitable, although use can also be made of polypropylene, plasticized polyvinyl chloride, super-polyamides, or mixtures of different thermoplastic materials, or even a metallic tube.
  • the operation which consists in bending the eduction tube 4 for the purpose of forming the elbow 54 can be carried out either in the cold state or in the hot state, for example by means of a suitable former.
  • the said bending operation is intended to produce a substantially permanent set in the tube 4, with the result that the ascending branch 55 is self-maintained in parallel relation to the descending branch 52, as shown in the example of FIG. 6.
  • the thickness of the tube wall increases with the internal diameter and can vary, for example, between 0.2 mm. and 2 mm.
  • the spacing of the perforations 31 as well as the size of these latter are not critical. However, it is advisable to ensure that the perforations 31 are sufiiciently close to each other in order that the number of perforations which are immersed in each of the two phases 32, 33 should be proportional to the depth of the corresponding phase within the container 1, with a view to producing a self-regulating action which will be explained in greater detail hereinafter.
  • the spacing can vary between a maximum of 15 millimeters and a distance which is as short as practical considerations will permit, taking account of the diameter of the perforations.
  • the stopper valve 3 which is of known design, consists of the discharge nozzle 58 which is adapted to actuate the flexible sealing disc 59 and is provided in the example considered with a valve head 14 of the type comprising a vertical flow cavity 61 (as shown in FIG. 7).
  • Said valve head which also is of known design, is characterized in that the internal passage 17 of the discharge nozzle 58 terminates in a slanting passage 62 which opens tangentially within the cavity 61, said cavity having a volume in the shape of a spherical cap. There is formed at the summit of said cap the spray discharge orifice 63 which is located at the bottom of a diffusion chamber 64.
  • valve body is not provided with a gas intake as in FIGS. 1-5.
  • the aerosol container 1 When ready for use, the aerosol container 1 is filled with aqueous phase 32 and with organic phase 33 and the dissolved active agent is present in at least one of these phases.
  • the valve head 14 When the valve head 14 is depressed, the said liquid phases flow simultaneously into the branch 55 of the eduction tube 4 under the action of the gas pressure and are driven along said tube. The said phases then pass through the elbowed portion 54 of the tube and flow upwardly within the branch 52.
  • a vertical flow motion F (as shown in FIG. 7) is imparted to said two phases as they enter the cavity 61 and propellant vaporizes at the same time. There is thus produced a high degree of atomization of the aqueous phase, which is expelled through the discharge orifice 63 in finely dispersed particles.
  • the gaseous phase which is present within the volume 34 of the aerosol container 1 is in fact not sucked through the eduction tube 4 although the perforations 31 of the upper portion of said tube are immersed in said phase, with the result that gas losses are extremely small.
  • This phenomenon is due to the fact that, by reason of the curve-d path of the eduction tube 4, the gaseous phase would have to pass through the aqueous phase 32 in order to escape, which is not possible in practice.
  • the composition of the dispersion is rendered more constant over the period of usage.
  • the above-noted phenomenon makes its possible to reduce the quantity of liquefied propellant which is introduced in the formulation and consequently to increase the proportion of water.
  • the aerosol container 1 has a cylindrical shape and that the openings in the eduction tube are equidistant, if the volume of one of the phases 32 or 33 is substantially greater than that of the other phase, a distinctly larger number of perforations 31 will be immersed in the phase of greater volume, with the result that the quantity of liquid drawn oif will also be larger.
  • the relative proportion of the two phases will therefore be reproduced in the mixture of phases conveyed to the level of the stopper valve 3.
  • the system thus automatically regulates the proportion of liquid dispersed, this being achieved also by virtue of the fact that the gaseous phase is not drawn through the eduction tube and by virtue of the fact that any danger of depletion of one of the phases relatively to the other is thus considerably reduced.
  • This self-regulating process makes it possible in particular to employ compositions having a preponderant aqueous phase.
  • the ascending branch 65 is shown in this example as being directed slantwise with respect to the descending branch 52 and the upper extremity of said ascending branch is brought to bear on the Wall of the container 1.
  • the eduction tube 4 thus assumes the shape of a V. This arrangement permits the possibility of increasing the spacing of the perforations 31 along the branch 65, all other things being equal.
  • the upper extremity 66 of the ascending branch 67 is bent back in the shape of a crook and secured by means of a tie 68 to the non-perforated descending branch 52 of the eduction tube. It is possible by means of this arrangement to make use of an eduction tube 4 fabricated of a flexible material such that the ascending branch could not remain of its own accord in the vertical-1y upright position shown in FIG. 6. As will be apparent, the crooked extremity 66 could also be welded to the branch 52.
  • the eduction tube 4 could also be formed of either natural or synthetic elastomers or mixtures of elastomers and plastomers (rubber, butyl rubber, mixture of polyethylene and polyisobutylene, for example).
  • the length of the eduction tube 4 is such that this latter has a tendency to unfold within the container 1.
  • the tube thus assumes a sinuous shape as shown in FIG. 10 and the ascending branch 69 thereof bears on the wall of the aerosol container 1 at different places. Only the upwardly extending portion 69 of the eduction tube 4 is perforated.
