  • 1 indicates a conventional can, having a top filling opening provided with a marginally curled edge 2 to receive in sealing relation the marginal curl 3 of a mounting cup 4.
  • the cup has a central crown 5 in which is supported a valve having a tubular valve stem 6 projecting upwardly therefrom.
  • a push button 7, such, for example, as shown in Robert H. Abplanalp Patent No. 2,884,207 is mounted on the valve stem and is placed thereon by the valve manufacturer at the time of assembling the cup, valve and button for shipment to a filler.
  • the push button 7 is provided with a discharge orifice leading from an expansion chamber within the button and the expansion chamber is in communication with a socket in the bottom of the button to receive the valve stem 6. All of these parts are well known.
  • the apparatus of the present invention is in the nature of an adapter, whereby a pressurized propellant may be fed from any suitable source as, for example, through a head h, FIG. 6, on a charging machine through the adapter to the valve operating push button and through thedischarge orifice of said button into the ,valve stem and thence into the can 1.
  • a pressurized propellant may be fed from any suitable source as, for example, through a head h, FIG. 6, on a charging machine through the adapter to the valve operating push button and through thedischarge orifice of said button into the ,valve stem and thence into the can 1.
  • the adapter shown in the drawings comprises an upper section 8 and a lower section 9, which sections are vertically movable relative to one another, as Well as in concert in an axial direction.
  • the upper section 8 for the purpose of convenient manufacture, embodies three parts 10, 11 and 12 secured to one another in superimposed relation so that said upper section constitutes a rigid assembly.
  • the lower section 9 is formed from two parts 13 and 14 which are rigidly secured to one another.
  • a slide 15 of hollow cup-shaped form Positioned in the uppermost part 10 is a slide 15 of hollow cup-shaped formprovided in its bottom with an opening 16.
  • a compression spring 17 interposed between the base of the hollow slide and a perforated disk 18 which is locked in place by a split ring 19.
  • the spring 17 normally forces the slide to a seat in the cavity 20 of the part 10 in which said slide is positioned.
  • valves 21 Supported on the slide 15, to project below the lower surface thereof, are two upper valves 21, arranged diametrically of the slide and these valvesare adapted to cooperate with elastic O-rings 22 which form valve seats therefor. Said O-rings are supported in circular depressions 23 in the upper surface of the part 11; An elastic packing ring 24 is positioned in the joint between the sections 10 and 11 to preclude leakage between these sections. Registering with each of the valve seat O-rings 22 and extending vertically through the section 11 are two passages 25 which extend downwardly to a chamber 26 at the base of the part 11.
  • a cylindrical socket 27 Positioned coaxially of the part 11 and extending from near, the top thereof to the bottom of said part is a cylindrical socket 27 in the lower portion of which is positioned a plunger 28.
  • This plunger is equipped with a packing ring 29 and is provided at its lower end with a sealing member shown as an insert 30 of Teflon or some other wellwearing meterial adapting it to cooperate with a lower valve seat 31 having a vertical central passage leading to radiating passages 32 in a lower valve seat member 33.
  • the socket 27 is peferably vented to the atmosphere, so that gaseous pressure cannot build up therein above the plunger 28. 7
  • the part 12 of the upper section 8 is provided with a shoulder 35 which clamps valve seat member 33 rigidly in place between said shoulder and sealing washer 36 and below said shoulder said par-t 12 is provided with a downwardly projecting tubular cylindrical portion 37, the lower end portion of which is counter-bored to receive a shank of an annular resilient gasket controlling member 38, the lower portion of which is beveled as shown at 39.
  • the upper part 13 ofthe lower section 9 is adapted to receive threaded studs 40 which extend upwardly and pass loosely through the lowermost part 12 of the upper section and are enlarged at 41 to provide heads which rest upon the upper surface of the part 12 and limit the downward movement of the section 9 with respect to the upper section.
  • These two sections are normally held in the distended relation shown in FIG. 1 by springs 42, but are adapted to approach one another and partake of the relative positions shown in FIG. 6 as hereinafter described.
  • the parts 13 and 14 of the lower section are rigidly secured to one another, as hereinbefore stated, and they are collectively provided with a coaxial bore 43 which closely embraces the cylindrical section 37 of the part 12 and the resilient member 38.
  • This bore 43 is provided at its bottom with an inwardly projecting annular flange 44 forming a seat for a washer 45 with a superimposed O-ring gasket 46 normally loosely surrounding the crown 5 of the can 1.
  • a ring 48 Seated upon a radially extending flange 47 of the part 11 is a ring 48.
  • This ring is composed of two semicircular parts, the opposite ends of which form a half lap joint with one another and are secured together by socketed screws 49, as shown best in FIG. 3.
  • the ring .48 carries two pins 50 which project into cavities 51 in part 11 and underlie upright rods 52 (see FIGS. 1 and 3). These rods extend upwardly through passages in the parts 11 and 10 and engage the slide 15.
  • the foregoing apparatus operates in the following manner:
  • the upper section will be lowered with respect to the lower section, so that the frusto conical or tapered portion 39 of the resilient member 38 will be forced downwardly to peripherally engage .
  • the O-ring gasket 46 and cause a tight constriction of said O-ring about the crown 5 of the can, to form a hermetic seal therewith and to also form a hermetic seal between the resilient member 38 and the wall of the bore 43, so as to preclude leakage at both of these locations.
  • the charging chamber C in which the assembled can parts are housed, will be hermetically sealed.
  • the studs 40 will remain stationary with the lower section 9, so that the upper surface of the flange 47 of the part 11 will withdraw downwardly from the ring 48.
  • the rods 52 will remain stationary and, as the upper section 8 continues to descend, they will serve to immobilize the slide 15, whereby the valves 21 will be withdrawn from their O-ring seats 22, as shown in FIG. 6. This will permit propellant under pressure to flow from the head It downwardly through the slide 15, valve seats 22, and passages 25 to the chamber 26 at the bo om of such passages.
  • the valve seat member 33 has descended into contact with the upper end of the valve operating button 7 and has depressed said button to open the valve of the container.
  • An adapter for pressure charging an aerosol dispenser container having a discharge valve provided with a valve operating stem comprising: a housing having therethrough a passage, the lower end of which forms a chamber to be hermetically sealed about the valve stem and a surrounding portion of the container when the adapter is pressed against the container, a nor mally sealed lower valve seat in said passage leading into said chamber, a mechanically operated upper valve also within said passage in the housing in advance of the lower valve seat to control the fiow of propellant to the lower valve seat, mechanical means operable by pressing the adapter against the container to open the upper valve, means to depress the valve stem of the container to open the valve thereof when the chamber is hermetically sealed, and a spring biased diiferential pressure operated valve member between the upper valve and the lower valve seat normally engaging'said lower valve seat and adapted to unseal the lower valve seat when the pressure of the propellant in said passage between the upper valve and the lower valve seat is suflicient to overcome the spring pressure on the differential pressure operated valve member.
  • Apparatus of the character described comprising: relatively movable upper and lower sections, the latter of which is provided with a charging chamber to receive and enclose a portion of the container to be charged, such enclosed portion including a valve stem, means for hermetically sealing said charging chamber about the enclosed parts of the container when the lower section is depressed by the upper section into engagement with the container, means for depressing the valve stem of the con tainer to open the valve of the container when the lower section is thus depressed, a lower valve seat having a passage leading to the charging chamber, a plunger the lower end of which is adapted for engagement with said lower valve seat, a spring acting on the upper end of the plunger to normally force the lower end of the plunger I into engagement with said lower seat, said upper section being provided with an inlet cavity for propellant under pressure, a passage leading from said inlet cavity to convey propellant under pressure upwardly against the plunger to retract the lower end thereof from the lower valve seat when such pressure of the propellant against the plunger exceeds the pressure of the spring acting on the upper
