Definitions

  • the radially extending portion of the male joint means is engaged over the radially extending portion of the female joint means between the radially extending portion of the female joint means and the member on which the female joint means is positioned, and the radially extending portion of the female joint means is engaged over the radially extending portion of the male joint means between the radially extending portion of the male joint means and the member on which the male joint means is positioned.
  • the cap member and the valve body member are thus tightly connected.
  • This invention relates to an aerosol dispenser, and more particularly relates to an aerosol dispenser of the type in which the product to be dispensed is contained in an outer product container separate from the propellant, the propellant being contained in an inner cartridge within the outer container.
  • the plug valve assembly includes a valve body which contains a valve mechanism that during dispensing controls the flow of the propellant and the product to be dispensed.
  • the usual form of dispenser has the outer container, the cap, and the valve body formed of one type of plastic. This plastic is usually a somewhat resilient and easily molded plastic.
  • the conventional manner of attaching the valve body to the underside of the cap is to provide a depending portion from the underside of the cap and a mating portion on the top of the valve body.
  • a conventional plastic joining step is carried out, such as spin welding, sonic welding, or heat sealing.
  • steps involve providing special joining equipment, such as welding .apparatus, in order to carry out these steps.
  • welding .apparatus special joining equipment
  • the joints are not always uniformly good, one operator sometimes making better or worse joints than another operator.
  • the heat from the joint can affect the dimensional tolerances of the adjacent parts to a greater or lesser degree, again depending to some extent on the skill ofthe operator.
  • cap and the valve body are also occasions when it would be desirableto have the cap and the valve body of different plastic materials, for example when the valve body is integrally joined to a propellant cartridge of a plastic which is impervious to the propellant, while the cap is ofa different plastic which need not be impervious to the propellant.
  • the parts are of different plastic materials, they cannot usually be joined by any of the conventional plastic-joining steps, such as spin welding or sonic welding.
  • an aerosol dispenser assembly in which the cap has a mating memberdepending from the underside of the cap, which mating member forms part of a mechanical joint, and the valve body of the plug valve assembly has the other mating member of.the mechanical joint on the top thereof.

The annular collar 10 is tightly engaged over the inwardly projecting flange 6a on the annular ring 6.
  • the valve body 7 can be made of one type of plastic, and'the cap 3 and depending annular ring 6 can be made of the same or a different type of plastic.
  • the male joint means of the connection i.e. the annular collar 10 on thevalve body 7 can be placed instead on the cap, so that the annular ring depending from the cap has an outwardly projecting annular collar thereon, and the female joint means is placed on the valve body 7 so that the inwardly extending annular flange 6a is on the valve body.
  • the remaining elements of the aerosol dispenser comprise a depending annular flange 11 depending from the valve body 7, to the lower end of which is attached a propellant cartridge 13 having therein a propellant 14 which normally is under high pressure in liquid form.
  • the upper edge of the propellant cartridge I3 is complementary in shape to the lower edge of the downwardly and outwardly flared portion 12 on the depending flange l1, and the parts are joined integrally with each other, for example by welding.
  • any other conventional connection can be used, such as bending the metal wall of a metal cartridge over the edge of the outwardly flared portion with a seal of some sort between the metal and plastic of the flared portion.
  • a ring gasket 15 Clamped between the annular crown 7a around the top of the valve body 7 and a downwardly extending projection 3b around the opening 30 in the cap 3 is a ring gasket 15 which acts as a low-pressure obturator for the admission of air to the product container 1 from outside the dispenser.
  • valve stem 5 extends through the hollow interior 8 of the valve body 7 and the opening 3a in the cap 3 opens into hollow interior 8.
  • a valve actuator in the form of a pushbutton I6 is mounted on the top end of the valve stem 5 and contains a nozzle insert 17 having a venturi-type spray nozzle therein. Nozzle insert 17 is set into a cavity in the pushbutton 16.
  • the opening 8 in the bottom of the body 7 opens into'the interior of cartridge I3.
  • a flange 19 on valve stem 5 is urged upwardly by a spring 20 around valve stem 5.
  • the lower end of spring 20 is held in a cup-shaped portion of a retaining ring 21 in the bottom of the hollow interior 8, and the retaining ring 21 is urged against the high-pressure gasket 9 in the bottom of the hollow interior 8.
  • the retaining ring 21 is held in the bottom of the hollow interior 8 by an annular ring-retaining projection 22 projecting into the hollow interior 8 at the upper end of retaining ring 21.
  • the spring acts to press the flange 13 upwardly so that the flexible lip of gasket 6 held between a truncated cone-shaped seat 13a on flange 13, cambered as shown, and the annular projection 3b around the edge of opening 3a in cap 3.
  • the pushbutton 16 which caps the valve stem 5 has two coaxial sockets at the base thereof, an outer socket defined by depending wall 23 and which fits tightly around valve stem 5, and an inner socket which receives the reduced diameter upper end 50 of stem 5.
  • the extent to which the sockets can be forced along valve stem 5 is limited by an annular shoulder 50 at the base of the upper end 50 of stem 5.
  • Stem 5 has splines 25 along the outside thereof defining between them channels 24 along the outside of the stem 5.
  • the channels open out of the stem through apertures 26.
  • the upper end of dip tube 27 opens into the hollow interior 8 and is force fitted in a bore 27a in body 7 for conducting material to be dispensed into the hollow interior 8.
  • Valve stem 5 is made in one piece, for example by molding, and has an axial bore 28 with a conical head 29 closing the lower end thereof.
  • a neck portion having a reduced diameter portion 290 in which is a plurality of lateral openings 30 which, when thevalve stem is in the raised position,-are obturated by the inner peripheral edge of gasket 9.
  • the gasket 9 In the lowered position of the stem 5, the gasket 9 flexes to open openings 30 to admit propellant to the axial bore 28.
  • depression of the pushbutton 16 flexes both these gaskets, opening the openings 30 to admit propellant to the bore 28 of the stem, thus aspirating the product to be dispensed through the dip tube 27, the hollow interior 8 past the now downwardly flexed gasket 15, through the passage 24 and through the apertures in the nozzle insert 17.
  • FIG. 2 An alternative form of the joint is shown in FIG. 2.
  • a male joint means in the form of an annular ring 32 having a wider portion 31a and a narrower inner portion 32b.
  • the portion ofthe ring 32 between the larger part 32a and the narrower part 32b is beveled outwardly.
  • Projecting radially outwardly from the lower end of the narrower inner portion 32b is an annular collar 33.
  • the annular collar preferably has a blunt pointed lower end 330, both edges of which are beveled and the upper surface of the annular collar 33 is inclined upwardly from the inner portion 32b.
