Definitions

  • Valve for delivering metered amounts of aerosol materials from containers therefor comprises two [30] Forelgn Apphcatlon pnonty Data bodies fast with each other and defining two distinct May 2, 1970 Italy 24095 A/70 chambers communicating with eauh when o of the chambers is connected to the container for the material [52] Cl 222/402-16 141/20 222/4022 to be delivered by a conduit, in which a piston is mov- [51] Ilit.
  • This invention relates to a valve for delivering metered amounts of aerosol materials from containers therefor, and more particularly a valve which can be applied to aerosol containers to supply a metered amount of the product in the containers and by which said containers can be pressure loaded.
  • a first known loading method consists of introducing into the container a liquid propelling gas, at a low temperature, in addition to the material to be delivered.
  • the delivery valve is then clawed to the container to isolate the interior of the container from the external environment.
  • the liquefied gas will change its state, pressurizing the vessel and thus placing the container under the conditions for enabling the delivery of the material in the bottle as an aerosol by operation of the delivery valve.
  • This filling system suffers from substantial disadvantages, because of requiring expensive cooling systems for the propelling gas which should be brought me very low temperature, frequently below 20C, in order to be maintained at a liquid state.
  • high propelling gas losses occur by evaporation when pouring off the liquefied gas into the container during the even minimal time between said liquefied gas pouring off into the container and container sealing by the delivery valve.
  • a second known method for filling an aerosol container consists of introducing pressurized propelling gas into the container through a metering-delivery valve previously attached to the container, into which the socalled active material of the aerosol product has been introduced prior to the sealing thereof by said delivery valve.
  • a valve having at least one element of deformable material which under the action of the external pressure is deformed during its loading step to allow for the introduction of liquid materials.
  • this element should be only deformable to allow for introducing materials into the container.
  • the deterioration of the material in the bottle consists of flavorings, colorings and the like in the material, whereby the more a valve costs, the less the amount of rubber used therein, that is, taking into account that rubber is usually used for providing the valve seals, it can be stated that the more the value of a valve, the smaller the rubber seals said valve is provided with,
  • Another object of the invention is to provide a valve by which a propelling gas can be introduced into a container by means of a gas introduction, high speed pressure system, without any risk of damaging the valve, also in the presence of high pressures within the valve during the above operation.
  • a further object of the invention is to provide a valve using rubber elements which may contact the material in the bottle, but which have extremely reduced dimensions and wherein all the other parts forming said valve are made of plastic material obtainable for example by injection moulding, thus avoiding the more expensive blow moulding system.
  • a further object of the invention is to provide a valve comprising a plurality of distinct parts which are firmly interconnected by simple contact, such as by friction or joint, avoiding any heat-welding between two different members forming the valve.
  • a valve comprising an elongated inner body attachable to a bottom which, in turn, can be applied to an aerosol material container, an outer body mounted on the inner body and a stem, a portion of which is accomodated within a chamber in the inner body and another portion of which emerges from said chamber, this chamber being formed at an end of the inner body, having an inlet closed by an outer seal through which said stem passes, and being defined by a side wall and a bottom wall, in each of which at least a small hole is formed, said bottom wall also having an aperture of a larger size than said small holes forming one end of an elongated tubular wall extending; outwardly of said chamber, an annular groove is formed on the outer surface of this tubular wall, while on the inner surface thereof a proJecting step is provided and at least one longitudinal groove having a limited length, one end of the last mentioned groove terminating in said chamber and the other end thereof opening intermediate the ends of said tubular wall, said outer body being substantially cup-shaped with
  • said small lateral hole of the stem is positioned outside of said chamber, beyond the outer seal closing the inlet and said small inner seal on the stem is located nearer to said chamber than the end of said longitudinal groove which terminates between the ends of said tubular wall, said stem being movable in opposition to said spring to an operative position, where said small lateral hole opens inside said chamber and said small inner seal is positioned contacting a smooth surface zone of said tubular wall in sealing engagement therewith.
  • FIG. 1 is an axial longitudinal sectional view showing an embodiment of the valve applied to a metal bottom
  • FIG. 2 is also an axial longitudinal sectional view showing a portion of the valve in FIG. 1, appliedto a different bottom.
  • FIG. 1 the axial longitudinal section is shown for a valve comprising an elongated inner body, at one end of which a chamber is formed having an inlet closed by a rubber outer seal 1 and defined by a side wall 2 and a bottom wall 3.
  • the free edge of side wall 2 has an enlargement 4, to which a metal bottom 5 is clawed and sealingly attachable due to the provision of a seal 6 on the inlet of an aerosol container.
  • Two small holes 7 are formed in wall 2 and a small hole 8 is formed in the bottom wall 3, in which an aperture of larger size than hole 8 is also formed, with said latter aperture forming the top end of a tubular wall 9 extending outwardly of said chamber, and, on the outer surface of which adjacent its lower end, an annular groove is formed, below which the tubular wall has an annular lug 10.
  • a projecting step 11 is formed, above which longitudinal ribs 12 project from the surface of wall 9.
  • an outer body is carried, substantially in the form of a cup having a free edge 15 which is resiliently deformable and with pressure overlies and bears against the side wall 2 of the inner body, said free edge 15 closing the small holes 7 in the side wall 2.
  • the outer cuplike body has a bottom 16 where an aperture is formed, wherein the tubular wall 9 of the inner body is inserted, at the annular groove of which said bottom is positioned and sealingly mounted and retained by the annular lug 10, as shown in the drawing.
  • annular groove 17 On the inner sur' face of bottom 16 of said outer cup-like body an annular groove 17 is formed, at which the lower end of a tube 18 is positioned fast with the tubular wall 9, and the other end of which opens at the hole 8 formed in the bottom wall 3 of the inner body.
  • the valve also comprises a stem, a portion of which is housed within the chamber defined by the walls 2 and 3 of the inner body, an another portion of which tudinal ribs project and in which an extension 23 is forcibly inserted and firmly retained, this extension forming a part of the other stem portion or piece also comprising a collar 24, a small post 25 projecting from the center thereof and having on its outer surface a number of longitudinal ribs, on which some turns of a spring 26 are superimposed and forced, some other turns of which are accomodated and forced between the longitudinal ribs 12 projecting from the inner surface of the tubular wall 9.
  • valve stem is lowered, that is the stem portion or piece 20 is partially re-entered into the interior of the chamber defined by the walls 2 and 3 of the elongated inner body, overcoming the strength of spring 26, until the small hole 21 is positioned within said chamber below the outer sealing gasket 1.
  • the pressure gas is now supplied to the valve and enters said chamber flowing between the seal 1 and the surface of the stem portion or piece 20 and through the small hole 21, and from said chamber enters the container mostly through the small holes 7 after causing the resilient deformation of the edges 15 of the outer body, and to a less extent through hole 8, tube 18 and escaping again between the wall 2 and the free edge 15 which is resiliently deformed.
  • the propelling gas pressure and its introducing speed are very high, the outer cup-like body is not separated from the inner body, because the anchoring between the two bodies is very strong and reliable, particularly due to the provision of said annular lug l0 and also due to the high frictional force between the wall 2 and edge 15 of the two bodies.
  • said small inner seal 27 is positioned below the lower end of the longitudinal grooves 13 on the tubular wall 9, and more particularly said seal is contacting a smooth surface zone at a cylindrical portion of the inner surface of said wall 9, said gasket providing for a complete sealing therewith.
  • the valve is mounted on a ready-touse container and a delivery cap of any known shape is mounted on the stem portion or piece 20.
  • the propelling gas enclosed within the container, to which the valve is applied causes the liquid or active material to move up through the bore of the drawing tube 14, through the bore or cavity of the tubular wall 9, causing it to flow into the grooves 13 and through the latter into the chamber as defined by said walls 2 and 3, and then causing it to enter the hole 8 and tube 18 and, through the latter, the gap between the inner and outer bodies of the valve, that is the space defined by the bottom wall 3 and the tubular wall 9 of the inner body and the walls of the outer cup-like body.
  • the aerosol material cannot come out of the axial stem hole 19, since the small hole 21 of said stem is positioned above the valve seal ll.
  • the small rubber seal 27 is positioned below the lower end of grooves 13, as previously mentioned, providing for a sealing relationship with the cylindrical smooth surface of a portion of said tubular wall 9 and preventing the liquid below said seal and within the drawing tube 14 from flowing into the chamber as defined by walls 2 and 3.
  • cross sectional sizes for the outer cup-like body that is the cross sectional sizes for that portion of said body projecting from bottom 16 may be different, thus making it possible to simply and readily provide valves for delivering predetermined .different amounts of aerosol material.
  • two-piece structure of said stem provides a simpler asa container inlet by upsetting said bottom from inside to outside.
  • FIG. 2 of the accompanying drawing a valve has been shown identical to that described in FIG. 1, but wherein said valve is mounted on a bottom 28 which can clawed on a container inlet by upsetting said bottorn from outside to inside.
  • valve can be adapted and readily mounted on the two types of commonly used bottoms and it is important to note that the actual deliveryingmetering valve portion is rigidly secured to a bottom, without taking advantage of or depending in the least on the coupling between the bottom and aerosol container for carrying out such a fastening.
  • a valve for delivering metered amounts of material from aerosol containers comprising an elongated hollow inner body having an interior chamber and being attachable to a bottom which, in turn, can be applied to an aerosol container, an outer body mounted on the inner body and a stem, a portion of which is accomodated within said chamber in the inner body and another portion of which emerges from said chamber, this chamber being situated at an end of the inner body and having an inlet, an outer seal closing said inlet and said stem passing through said outer seal, and said chamber being defined by a side wall and a bottom wall, in each of which at least one small hole is formed,
  • said bottom wall also having an aperture of a larger size than said small holes, and an elongated tubular wall having an open end formed by said aperture of larger size and extending outwardly of said chamber and having an outer surface formed with an annular groove, while said tubular wall has at an inner surface thereof a projecting step and is formed with at least one longitudinal groove having a limited length, one end of the last mentioned groove opening into said chamber at said aperture of larger size and the other end thereof terminating intermediate the ends of said tubular wall, the latter having a smooth surface zone inwardly beyond said longitudinal groove, and said outer body being substantially cup-shaped and having a free edge resiliently deformable and overlying with pressure the side wall defining said chamber, closing the small hole formed therein, the outer body in the form of a cup having a bottom formed with an aperture wherein said tubular wall of the inner body is inserted, and said bottom of said outer body being positioned and firmly and sealingly mounted in said annular groove of said elongated tubular wall, said stem being formed with an axial hole in
