  • This invention relates to a valve for a pressurized aerosol dispenser.
  • a valve hous ing having a notched or castellated upper rim which permits the annular valve gasket to be deflected by the pressure of propellant gas when the container is being charged.
  • the aerosol dispenser comprises a valve housing within which is found a movable valve member having an upstanding hollow valve stem.
  • An annular resilient gasket of washer shape surrounds the valve stem and blocks a transverse valve orifice which communicates with a hollow interior of the stem.
  • This assembly of housing, movable valve member, gasket and spring is positioned within a valve mounting pedestal formed in a valve mounting cup.
  • the valve stem protrudes through an aperture in the end wall of the pedestal portion.
  • the valve mounting cup is a metal member which serves as an end closure for the container and is adapted to be affixed to the container mouth aperture,
  • the valve is actuated for dispensing purposes by de pressing the upstanding valve stem inwardly of the container, thereby deflecting the inner margin of the annular resilient gasket away from blocking relationship with the valve orifice. This establishes communication of the hollow upstanding valve stem with the interior of the dispenser container through the valve housing and the product eduction tube. Propellant gas provides the pressure necessary to force the product up the eduction tube, through the valve housing, through the valve orifice and up the valve stem.
  • a dispensing button having a dispensing orifice of appropriate form is usually affixed to the upstanding valve stem by friction. Such a valve is described in US. Pat. No. 2,631,814.
  • Pressurized dispensers having valves of the type above described are frequently filled by introducing the.
  • mounting cup is sealingly affixed to the mouth aperture of the container.
  • propellant is introduced under reltively high pressure by bringing a charging head into communication with the valve stem.
  • the valve stem is depressed to open the valve and propellant under pressure flows through the stern and through the valve orifice into the container. Because the valve orific e is of relatively small dimension, such a filling procedure is relatively slow. It is known to establish filling paths auxiliary to the product flow paths for more rapid charging of the container.
  • a charging head which presents propellant under pressure to the valve stem aperture of the mounting cup pedestal portion outside the valve stem. The pressure of the propellant deflects the inner margin of the sealing gasket away from the valve stem to provide an annular entrance surrounding the valve stem.
  • propellant passes into the container by separate paths inside and outside the valve stem.
  • auxiliary filling paths for the propellant are formed by openings in the end wall of the valve mounting cup pedestal portion.
  • the annular sealing gasket extends radially outwardly from the clamping edge of the valve housing to cover these openings.
  • the pressure of the propellant deflects the outer margin of the sealing inwardly and away from these openings to establish auxiliary paths.
  • the pressure of the propellant within the container forces the outer margin of the sealing gasket into sealing engagement with these holes.
  • the present invention is concerned with providing an auxiliary filling path for propellant under pressure which more reliably seals and provides less flow restriction than do the above-described auxiliary filling paths.
  • the sealing gasket is clamped between the end wall of the valve mounting cup pedestal portion and a rim of the valve housing which has projections or castellations outwardly of the uninterrupted inner margin of the rim.
  • the inner margin effects a uniform clamping of the gasket while the projections provide regions of the gasket which are not supported or clamped. These unsupported or unclamped regions between the projections are free to deform under filling pressure and provide auxiliary filling paths outside the valve housing which originate at auxiliary apertuers in the end wall of the mounting cup pedestal portion.
  • the projections clamp the outer margin of the gasket for tight sealing after filling.
  • Auxiliary filling paths exterior to the valve housing are advantageous because there is less flow restriction than paths through the valve housing and because the high pressures employed during filling sometimes cause explosion or distortion of the valve housing when all the propellant must pass through the valve housing.
  • the projections are radial ribs issuing from the clamping edge of the inner margin of the rim of the valve housing. These ribs hold the sealing gasket fast against the inner surface of the end wall of the valve mounting cup pedestal portion. Additional apertures through the end wall surrounding the valve mounting cup aperture may be employed. The ribs help hold the sealing gasket in sealing relationship with the additional apertures. Where radial ribs and additional apertures are employed together, it is advantageous to make the number of additional openings and the number of ribs differ by one or more to insure that the ribs cannot be positioned such that they will block all of the auxiliary openings.
  • the projections are in the form of columns radially spaced from the inner margin clamping edge.
  • FIG. 1 is a longitudinal section taken along line A-A of FIG. 2 through a valve having a housing according to the first embodiment;
  • FIG. 2 is a plan view of the sealing gasket and the valve housing of FIG. 1;
  • FIG. 3 is a perspective view of the upper portion of the valve housing of FIG. 1;
  • FIG. 4 is a longitudinal section of a portion of a valve having ahousing according to the second embodiment.
  • FIG. 5 is a perspective view of the upper portion of the valve housing of FIG. 4.
  • FIGS. 1 through 3 there is illustrated a first embodiment of the present invention.
  • valve assembly comprising a valve housing 11, a valve body 17 having an upstanding valve stem 6, a closure biasing spring 16 and a resilient annular sealing washer 9 are assembled and clamped within a valve mounting pedestal portion 3 of a metal valve mounting cup 2 by means of the indentations or crimps 14 formed inwardly in the metal of the valve mounting cup pedestal portion and under a tapered shoulder 14 formed on the upper part 12 of the valve housing 11.
  • the crimping operation upwardly forces the valve housing 11 to cause the clamping edge to compress and sealingly engage the gasket 19.
  • An actuator button 7 is frictionally fitted to the upstanding valve stem 6.
  • the stem 6 protrudes through an aperture 27 in the end wall 4 of thee pedestal portion 3.
  • the actuator button includes a discharge orifice 8 and passages 5 of the valve stem 6 which communicate with the bore.
  • a longitudinal passage 25 is provided for conveying propellant during the charging operation.
  • a product eduction tube is fitted to the lower end of'the valve housing 11 and surrounds the inlet to the valve housing.
  • a valve orifice l9 permits communication of the bore 5 of the upstanding valve stem 6 with the interior of the valve housing 11 when the valve stem is depressed.
  • the inner margin of the gasket 9 is deflected downwardly and away from blocking relationship with the valve orifice 19 to permit product under pressure to flow up the product eduction tube 15, through the interior of the valve housing 11, through the valve orifice l9 and into the hollow bore 5 of the valve stem.
  • the discharge button 7 includes passages which extend from the valve stem bore 5 to the discharge orifice 8 to permit dispensing of the product.
  • the valve housing of the present invention is illustrated in perspective in FIG. 3.
  • the housing 11 includes four radial ribs 22 which extend radially outwardly of the clamping edge 10 at the inner margin of the housing 11. Intermediate the radial ribs 22 are sloping regions 21 which permit the downward deflection of the resilient gasket 9 during the filling operation. Longitudinal grooves 23 in the enlarged upper portion 12 of the valve housing 11 provide propellant flow passages leading to the interior 24 of the container 1.
  • FIG. 2 shows the relative arrangement of the ribs 22 on the upper rim of the valve housing 11 and a series of auxiliary openings through the end wall 4 of the valve mounting cup pedestal portions 3. Openings 20 are located radially outward of the valve stem aperture 27. As illustrated in FIG. 2, there are four radial ribs and five auxiliary filling openings 20. As a consequence, no relative rotation of the housing with respect to the end wall 4 will block all of the openings 20.
  • valve just described operates in the fashion ordinary to such valves. It is during the operation of filling or charging the aerosol dispenser container 1 with propellant what the valve of the present invention differs in operation from those of the prior art.
  • a charging head (not shown) connected to a source of propellant under relatively high pressure is positioned to encompass the valve stem 6 with or without button 7 and at least the valve mounting cup pedestal portion 3 of the container.
  • the charging head is sealingly engaged with the container to prevent waste of propellant.
  • the charging head is normally arranged to effect depression of the valve stem to open a first charging path extending from the discharge orifice downwardly through the valve stem bore 5 and through the orifice l9 and valve housing 11 into the interior of the container through the product eduction tube 15.
  • the auxiliary filling path of the present invention conveys propellant through the longitudinal passage 25 of the button to a chamber 26 on the under surface of the button.
  • the lower margin of the button engages the end wall 4 of the valve mounting cup pedestal portion to complete the integrity of the chamber 26.
  • Propellant in either a gaseous or liquid state is thereby present at the auxiliary filling apertures 20.
  • the pressure of propellant downwardly deflects those portions of the annular gasket 9 which lie radially outward of the clamping rim l0 and span the regions 21 between the radial ribs 22 of the upper rim of the housing 11.
  • a known further charging path is also established. This path leads from the valve stem aperture 27 past the downwardly deflected inner margin of the gasket 9 and into the valve housing 11.
  • the charging head Upon completion of the charging operation, the charging head is withdrawn and the valve is allowed to close returning the downwardly deflected inner margin of the gasket 9 into sealing engagement with the valve stem 6 thereby sealing the valve orifice 19 and allowing the pressure within the container and the elastic characteristics of the resilient gasket 9 to return to sealing engagement with the inner surface of the end wall 4 those outer portions of the gasket which had been deflected downwardly to form radial passages over the spans between the radial ribs 22.
  • FIGS. 4 and 5 a similar construction is shown wherein similar parts are provided with the same numbers as were used in the description of the embodiment of FIGS. 1 through 3. Parts related to those described in connection with FIGS. 1 through 3, but not identical, are given the numbers of the parts to which they relate with added.
  • a plurality of columns 122 are employed instead of the radial ribs 22. These columns are provided with a downwardly sloping upper surface 128. Columns 122 are radially separated from the inner margin clamping rim 10 to provide a deflection space 121 between adjacent columns and between the columns on the rim into which the gasket is deflected by the pressure of the propellant during the filling operation.
  • the columns 122 are located close to the outer periphery of the gasket 9. The columns press peripheral portions of the gasket against the end wall 4 of the valve mounting cup pedestal portion 3 upon completion of the charging operation. Because the deflection space 121 also extends between the ring of columns 122 and the clamping edge 10, there is no danger of blocking openings 20. The number of openings 20 and columns 122 need not be related to unequal as was the preference with respect to the first embodiment. With the valve housing 111 of the second embodiment, there ordinarily exists a space 123 through which the propellant can flow. Longitudinal grooves 23 such as were employed with the first embodiment are unnecessary.
  • a valve for a pressurized dispenser comprising a valve housing within which is arranged a movable valve member having an upstanding hollow valve stem provided with a transverse aperture, said valve housing being secured to a valve mounting cup which cup includes an end wall having an aperture through which the valve stem projects, and an annular resilient sealing gasket surrounding the valve stem and normally sealing said transverse orifice, wherein the upper rim of the valve housing comprises an uninterrupted inner margin which clamps the sealing gasket against the inner face of said end wall of the valve mounting cup and an interrupted outer margin formed by valve housing projections which additionally clamp the sealing gasket against said end wall of the valve mounting cup, the spacers between said projections accommodating unclamped portions of said sealing gasket when deflected under pressure when propellant is charged through propellant inlet means in said end wall of the valve mounting cup.
  • valve mounting cup surrounds a peripheral portion of the valve housing and longitudinally extending, open-ended grooves between said portions communicate at their upper ends with the spaces between said projections.
  • a valve for a pressurized dispenser comprising a valve housing within which is arranged a movable valve member having an upstanding hollow valve stem provided with a transverse aperture, said valve housing being secured to a valve mounting cup having an end wall which includes an aperture through which the valve stem projects and inlet means therethrough disposed radially outwardly from said aperture and an annular resilient sealing gasket surrounding the valve stem and normally sealing said transverse orifice and said inlet means said valve housing having an upper rim which comprises a clamping edge which seals the gasket against said end wall I a plurality of clamping projections spaced from each other and disposed outwardly ofsaid clamping edge and said projections providing unclamped portions of said gasket between spaced clamped portions, and
