Definitions

  • the present invention relates to aerosol valves and more particularly to the mounting cap for supporting such a valve and mounting it in an opening in a container to provide a closure therefor.
  • a unit comprising a mounting cap member which supports a valve housing having therein a valve member which seats against a sealing washer.
  • the cap member is usually cup-shaped with the outer wall of the cup formed with a peripheral flange for attachment to a container and a bottom wall formed with a reentrant inverted cupshaped pedestal which supports the valve housing and has an opening in its base through which projects a valve stem.
  • the units are tested for fluid tightness, then crimped onto the container, after the active ingredients are placed therein, and the pressurizing agent is added either before crimping the unit onto the container where the container is to be cold filled or after the crimping operation where the container is to be pressure filled.
  • FIG. 1 is a diametrical section of the mounting cap, embodying the invention, prior to assembling the valve parts therein;
  • FIG. 2 is a top plan view of the mounting cap shown in FIG. 1;
  • FIG. 3 is a diametrical section of a testing station whereat the tightness of the aerosol valve unit is pressure tested, the unit being shown in elevation;
  • FIG. 4 is a side elevation of an aerosol valve unit in the course of being mounted in the opening of a container and illustrating the self-centering characteristic of the unit;
  • FIG. 5 is a diametrical section of an aerosol valve unit embodying the invention mounted on a container and the relationship of a filling head applied thereto when the container is being pressure filled.
  • the mounting cap which is designated as a whole by the reference numeral 10 may be said to consist of a cup-shaped member 11 having a peripheral wall 12 which is substantially cylindrical and terminates at its outer end in a substantially semicircular annular flange 13 and with a reentrant inverted cup-shaped portion 14 extending into the cup-shaped member 11 from the bottom wall of 15 thereof.
  • the inverted cup-shaped portion which is sometimes referred to as a pedestal may have an axial dimension as desired and has a peripheral wall 16 which is radially spaced from the peripheral wall 12, a bottom wall 17 formed with a central perforation 18 and with a lip flange 19 which extends downwardly and radially outwardly.
  • the bottom wall 15 of the cup-shaped member 11 tapers downwardly and radially inwardly and forms with the lip flange 19 a reinforcing ridge-like rib 20.
  • the angularity of the tapered bottom wall 15 and the lip flange 19 may vary as desired but it is preferable that the bottom wall 15 should have a radial dimension a least equal to one half of the distance between the peripheral walls 12 and 16 and form with an imaginary plane extending across the crown of the rib 20 an angle x of between 15 and 30 and with the lip flange 19 an angle y suflicient to substantially reinforce the bottom of the cap member.
  • the angle x should be approximat-ely 20 and the angle y approximately 60.
  • the cupshaped member 11 may be formed of any suitable sheet material by stamping or drawing operations well known in the art.
  • mounting cap- 10 is shown as mounted on and supporting the valve elements of a valve which may be of any desired construction and provide an aerosol valve assembly.
  • the valve elements and their relationship to the mounting cap are analogous to those disclosed and forming the subject matter of a copending application of Joseph Briechle, Serial No. 225,087, filed September 20, 1962, now Patent No. 3,158,298 and consists of a tubular housing 21 having mounted in the chamber thereof a sealing gasket 22, a discharge valve 23 having a hollow valve stem 23a and a spring 24 for biasing the valve 23 into sealing engagement with the underside of the gasket 22.
  • the tubular housing has an external flange or enlargement 25 formed with circumferentially spaced axially extending ribs, the upper ends of which form a castellated top on the valve housing and it is around said flange or enlargement 25 that the inverted cup-shaped portion 14 engages by the bottom wall 17 thereof seating over the castellated top of the valve housing and the side wall 16 thereof being swaged, staked or crimped over the lower edge of the enlargement as shown at 26 with the valve stem 23 slidably extending through the sealing gasket 22 and freely movable through the opening 18.
  • the valve assembly unit is also shown as provided with a dip tube 27 and an operating button or actuator 28.
  • valve assembly unit as above described is shown in elevation in the course of being tested for fluid tightness of the assembled valve in which operation the valve assembly unit is fed to a testing station of an assembly machine having a gasket 29 into the hole of which the conical bottom wall 15 of the cap member seats and assures a dependable seal when a force F is applied to the flange 13 and fluid pressure is applied upwardly against the bottom of the mounting cap as indicated by the arrows and the legend pressure.
  • FIG. 4 there is depicted the relationship of the valve assembly unit when placed in the opening in the top of a container 30 on the filling line conveyor (not shown) to illustration how the valve unit will be self centering and locate itself in the opening in the event that the unit originally is not properly positioned in the container.
  • the conical bottom wall 15 of the cap member will guide the unit to facilitate the crimping or roll seaming of the valve unit onto the container as shown completed at FIG. 5.
  • angles x and y will be somewhat altered as will also be the shape of the peripheral wall 12a of the cap member (FIG. but these changes in shape of the angles x and y are not sufficient to affect the various advantages of the mounting cap as disclosed.
  • valve assembly unit illustrated is of the fast pressure filll type disclosed and claimed in the aforementioned Patent No. 3,158,298, i.e., an assembly unit through which the propellant is charged into the container so as to flow between the inverted reentrant cup-shaped portion 14 and the tubular housing 21 through the castellated top of said housing and the axial grooves or spaces in the external flange or enlargement 25.
  • the propellant will flow through the annular space between the boundary of the central perforation 18 in the pedestal and the valve stem to act against the exposed inner central portion of the sealing gasket 22 andoperate to axially move said gasket bodily within the tubular housing out of contact with the top flange 17 of the pedestal to expose the grooves in the castellated top of the housing and the spaces between the ribs on the exterior of the housing which communicate with the grooves in the castellated top to provide a flow path for the propellant through said grooves into the container 30 as indicated by the arrows.
  • the annular groove between the pedestal and the outer wall of the cap member By making the annular groove between the pedestal and the outer wall of the cap member sufficiently deep, better sealing of the filling head on the pedestal is assured notwithstanding slight variations in the height of the container in relation to such filling head. Also, by virtue of the rib 20 in the bottom wall of the mounting cap, the latter is reinforced and will prevent or reduce to a minimum downward distortion of the pedestal during pressure filling.
  • the pressure within the containers at room temperature is about 40 p.s.i. and in order to make certain that no potential leaks exist, the valve, the container, and the integrity of the cap to the container at the crimp therebetween, the containers are tested under a pressure of 120 p.s.i.
  • Such increased pressure is obtained by heating the container and its contents to 150 F. in a hot water bath.
  • the reinforcing rib 20 which substantially strengthens the container cap, said cap is less likely to dome outwardly due to pressure buildup within the container while in the hot water bath.
  • a mounting cap for an aerosol valve assembly which mounting cap prior to having the valve parts assembled therewith, comprises a cup-shaped member having a reentrant inverted cup-shaped portion extending into the cup-shaped member from the bottom wall thereof in radially spaced relation to the peripheral side wall of the cup-shaped member and said bottom wall having a portion that tapers downwardly and radially inwardly from the inner end of said peripheral side wall.
  • a mounting cap according to claim 1 wherein the tapered wall portion of the bottom wall forms with said peripheral side wall an interior angle of at least 4.
  • a mounting cap according to claim 1 wherein the radially inner end of said tapered wall portion of the bottom wall forms with the rim of the inverted cupshaped portion, a reinforcing rib.
  • An aerosol valve assembly unit comprising a cupshaped mounting cap having a re-entrant inverted cupshaped portion extending from the bottom wall in radially spaced relation to the peripheral side wall of the cap, said reentrant inverted cup-shaped portion supporting the valve operating parts and said bottom wall being tapered downwardly and radially inwardly from the inner end of said peripheral side wall of the mounting cap.
