Definitions

  • This invention relates to a dispenser assembly and a combination therewith of a pressurized package, and more particularly, to such packages and assemblies useful for effecting discharge of a fluid composition by the action of a pressurizing propellant.
  • dispenser assemblies or valves are available for use in such packages to permit the propellant to drive the liquid composition to atmosphere usually through a dip tube extending from the valve down towards the bottom of the package.
  • valves While some of these valves are arranged simply for direct discharge of product to atmosphere, others employ a vapor tap principle according to which some gaseous propellant is admixed with the product as it passes through the valve so that, upon reaching atmospheric pressure, the propellant expands rapidly and assists in breaking down the particles of product into exceedingly fine form. Nevertheless, it has been observed that due to the pressure drop through many types of valves, products having certain characteristics tend to drool and leave a residue in the discharge package after the valve is shut, and this may lead to clogging of the discharge passages. Accordingly, there has long been a need for a package of the class described in which such drool or after-drip is avoided.
  • I provide a pressurized package of the class described including a container, a fluid composition in the container, propellant means also in the container, and a dispensing assembly mounted in the container and comprising a body having an inlet and outlet means, means effecting communication between the body inlet and the interior of the container, a housing within the body formed with an internal chamber in communication with the inlet, the housing cooperating with the body to define a second chamber therebetween, an orifice in the body effecting communication between the second chamber and the interior of the container, first sealing means normally closing the orifice, and second sealing means normally sealing the outlet means from communication with the internal chamber and permitting communication between the outlet means and the sec- 3,497,112 Patented Feb. 24, 1970 ond chamber.
  • the first sealing means is shiftable to uncover the orifice and the outlet means is shiftable to a position relatively to the second sealing means to seal same from communication with the second chamber and to place same in communication with the internal chamber whereby fluid composition is propelled through the body inlet, the housing and the outlet means and propellant is admitted into the second chamber.
  • Spring means are provided urging the first sealing means and the outlet means to normal position whereby the outlet means is sealed from the interior of the container and is placed in communication with the second chamber so that propellant expands through the outlet means flushing same, and the first sealing means seals the orifice.
  • a further feature of the present invention resides in provision of an outlet passage in the outlet means open to atmosphere and formed in a stem that passes through the valve body and is arranged to be depressed by the application of an external force against the action of the spring means.
  • the spring means comprise two springs, the first of which urges the stem toward normal position; and the second of which urges the first sealing means towards normal position, the spring force of the first spring being greater than that of the second spring.
  • FIG. 1 is a profile view of a package in combination with dispensing means according to the present invention
  • FIG. 2 is a cross-sectional view taken along the lines 22 of FIG. 1;
  • FIG. 3 is a cross-sectional view taken along the lines 3-3 of FIG. 2;
  • FIG. 4 is a vertical section of the dispensing assembly illustrating same in its product discharge position
  • FIG. 5 is a view similar to FIG. 4 but illustrating same in normal position after discharge and with flushing taking place.
  • FIGS. 1 and 2 there is shown a pressurized package 10 including a conventional aerosol can 11 having a domed top 12 and a dispensing assembly 14 mounted centrally of the top with a depressible stem 15 protruding therefrom.
  • a conventional head may be formed or fitted to the uper end of the stem to direct the discharge and control its emission as desired, but such as not part of this invention and so is not shown.
  • the valve body 16 is formed with a downwardly inclined shoulder 17 and an upper rim 19 against the latter of which rests a gasket 20 having a central opening through which the stem 15 passes.
  • the entire assembly is supported by means of a thin metal member 21 crimped against the shoulder 17 and around and over the gasket 20.
  • the body 16 is generally cup-shaped and has a depending cylindrical configuration 22 at its lower central region into which is press fit a dip tube 24 which extends down to the bottom of the can.
  • An orifice 25 is shown formed at the side of the body 16 although it will be appreciated that several such orifices may be used.
  • a cup-shaped housing 30 is positioned within the body 16 and is formed with a downwardly depending central cylindrical passageway 31, an external downwardly facing shoulder 32 and a pair of spaced outwardly extending guide rings 34 having vertical grooves 35 therein for the passage of fluid. As shown in FIG. 3, the lands 36 formed by the grooves 35 bear against the inner wall of the body 16 to guide the housing 30 for vertical movement therein.
  • annular groove 37 into which is crimped a flange 39 formed on a metal disc 40 which is positioned horizontally across a gasket 41 that is thereby pressed against the upper rim of the housing 30.
  • the disc 40 and gasket 41 have central openings through which the stem 15 extends, the gasket providing a seal at the housing rim and at the stem.
  • the disc 40 is relatively thick and is formed with a plurality of radial grooves 42 cut into its top surface and extending downwardly at the sides thereof for a purpose later to be described.
  • the stem 15 is formed with a central, vertical bore 44 and with an enlarged base which provides an upwardly facing shoulder 45 that normally engages the underside of the gasket 41, as shown in FIGS. 2 and 5.
  • One or more openings 46 are formed in the stem 15 at a position to place the bore 44 in communication with the grooves 42 when same is in its normal position (FIGS. 2 and although only one such opening is shown.
  • the stem 15 is maintained in its normal position, that is with the shoulder 45 against the gasket 41 by a spring 47 which bears between the base of the stem and the bottom of the housing 30; and a second spring 49, hearing between the bottom of the body 16 and the bottom of a gasket 50 normally maintains the gasket 50 against the shoulder 32 and in sealing relation to the orifice or orifices 25, as the case may be, and thus urges the housin g 30 towards its upper limit of movement.
  • the housing 30 could, of course, be formed with a larger diameter at its base and be provided with an O-ring in lieu of the gasket 50 to seal off the orifice 25.
  • the spring 47 is preferably stronger, i.e. of greater spring force than the spring 49.
  • the stem is depressed until the openings 46 are positioned below the gasket 41 at which point fluid flow communication is established between the dip tube 24 through which product is driven by the propellant in the can, the body 16 below the gasket 50, the cylindrical passageway 31 at the bottom of the housing 30, up through the interior of the housing around the base of the stem 15, through the openings 46, up the vertical bore 44 and to atmosphere.
  • the spring 47 is stronger than spring 49 and since spring 47 bears at its lower end on the housing 30, it will be appreciated that before the stem 15 descends relatively to the housing 30 and gasket 41, the spring 49 collapses so that the housing, stem nad gasket 50 move downwardly together, the latter uncovering the orifices 25 and allowing propellent from the top of the can to enter the space or chamber between the body 16 and housing 30. Further depression of the stem 15 collapses the spring 47 allowing the openings 46 in the stem to move below the gasket 41 to discharge position, the gasket 41 sealing the openings 46 from communication with the propellant in the chamber between the housing and body and trapping the propellant there.
  • the springs 47 and 49 act to return the parts to normal position.
  • the openings 46 in stem 15 move upwardly through gasket 41 which acts to seal those openings from the interior of the housing 30 and terminating discharge of product com-position.
  • the gasket 50 is moved upwardly by the spring 49 to seal the orifices 25, thus breaking fluid flow communication between the upper region of the can and the chamber between the housing and body; and as the openings 46 in the stem 15 reach normal position in communication with the grooves 42 in the disc 40, the pressurized propellant in the chamber between the housing and body expands through those grooves and openings and up the bore 44 to aimosphere clearing the latter and any head which may be used of residual drool or after-drip which might otherwise have remained there. It will be appreciated that by proper sizing of parts the quantity of propellant employed to clear the discharge bore may be carefully controlled.
  • a valve body having an inlet and outlet means, a housing within said body formed with an internal chamber in communication with said inlet, said housing cooperating with said body to define a second chamber therebetween, an orifice in said body communication with said second chamber, first sealing means normally closing said orifice, second sealing means normally sealing said outlet means from communication with said internal chamber and permitting communication between said outlet means and said second chamber, said first sealing means being shiftable to uncover said orifice and said outlet means being shiftable to a position relatively to said second sealing means to seal same from communication with said second chamber and to place same in communication with said internal chamber, and spring means urging said first sealing means and outlet means to normal position.
