Definitions

  • the present invention relates to aerosol containers and more particularly to a mounting cup and valve assembly for an aerosol container, made substantially wholly of plastics materials.
  • Containers for aerosols are at present generally manufactured with a metal or glass container, to the upper rim of which is crimped a metal valve mounting cup.
  • Figure 1 shows a typical mounting cup assembly in which a mounting cup 10 is provided with a circumferential flange 11 which is adapted to be crimped to the upper edge of a suitable container.
  • a valve assembly indicated generally at 12 To the mounting cup is attached a valve assembly indicated generally at 12 and around which the central portion 13 of the mounting cup is crimped to make contact with sloping faces 14 on the valve housing 15. This results in the upper edge of the valve housing 15 being held securely against a sealing gasket 16.
  • the contents of the container are released " y displacing the stem 17 against the action of the spring 18 to allow the contents of the container to pass through the passage 19 into the bore 20 of the stem.
  • a plastic mounting cup could be used either with a metal container of the existing type or with a plastic container to which it could be readily attached.
  • Aerosol containers including such conventional mounting cup and valve assemblies are filled with propellant through - 2 -
  • the present invention in a first aspect consists in a mounting cup and valve assembly for an aerosol container comprising a mounting cup moulded from plastics material, the cup having means around its periphery whereby it is adapted for connection to a container, a central aperture in the cup surrounded on its underside by a gasket, a valve assembly on the underside of the cup having a stem projecting through the aperture in the housing and being in sealing contact with the gasket, a skirt-like member moulded integrally with the cup and projecting downwardly around the gasket and the housing, and defining an annular space between the housing and the skirt-like member, the skirt-like member including apertures in communication with the annular space and bearing, at its end distal to the cup, engagement means, an annular locking -mem er surrounding the housing and engaging with the radially inner and radially outer surfaces of the skirt-like mem b er, the locking member including complimentary engagement means which co-operate w i th the engagement means on the skirt-like member and
  • the arrangement according to the present invention allows very much faster filling of aerosol containers than was previously possible using all plastic mounting cups and valves.
  • the presence of an annular space between the housing and the skirt-like member and the apertures in the skirt-like member allow pressure filling of the aerosol container through the valve at a high rate.
  • the propellant flows through and around the valve stem, displaces the gasket downwardly and flows past the gasket into the annular space and thence into the container.
  • the presence of the locking member surrounding the skirt-like member prevents the free end thereof expanding and thus prevents displacement of the housing within the cup.
  • the skirt-like member formed integrally with the cup prefera b ly includes a plurality of longitudinally extending slots which constitute the apertures.
  • the free end of the segment of the skirt-like member defined by the slots preferably each include a cir ⁇ um erentially extending rib on its radially outer surface which ribs together constitute the engagement means.
  • the locking member is preferably formed on an independent part of U-shaped cross-section having a base and two upwardly extending annular flanges, the radially inner one of which extends into, and fills, the lower end of the annular space between the housing and the skirt, while the radially outer one closely surrounds the radially outer surface of the skirt-like member.
  • the locking member may be formed integrally with the housing preferably formed on that portion which projects into the annular space with a tapered end which is adapted to engage with a correspondingly tapered shoulder on the housing.
  • the portion of the locking member which surrounds the skirt-like member is preferably formed on its radially inner surface with an annular groove or recess constituting the complimentary engagement means and adapted to resiliently engage with the circumf rential ribs on the radially outer surface of the skirt-like member.
  • the cup itself may be connected to a metal, glass or plastic container b y any one of a number of conventional ways.
  • a screw threaded annular collar may be used to hold the cap down on the bottle or other container having a complimentary threaded neck.
  • the cap may have a downwardly extending peripheral collar which clips over a corresponding peripheral flange surrounding the open top of the container.
  • the cup may also be connected to a plastic container by welding, particularly spin welding or sonic welding, the plastics parts together.
  • Figure 3 is a similar view of a modified form of the invention and includes inserts showing details of the manner in which the mounting cup may be secured to the container;
  • Figure 4 is a similar view of the construction shown in Figure 2 showing details of further forms of construction by means of which the mounting cup may be secured to the container; and Figure 5 is a similar view showing a modified form of construction in which the locking means forms a part of the valve housing.
  • FIG 2 the central portion of a mounting cup and valve assembly which consists of a mounting cup 30 moulded from any suitable plastic material such as polyethylene terephthalate, nylon, or polypropylene.
  • a gasket 31 On the underside of the central raised portion of the mounting cup 30 is a gasket 31 through which the stem 32 of a conventional aerosol valve assembly 33 projects.
  • the valve 33 is surrounded by a housing 34 also of conventional construction and normally moulded from nylon. As can be seen from Figure 2 the upper edge of the housing 34 makes sealing contact with the gasket 31.
  • This sealing contact is maintained by means of a downwardly extending skirt 35 divided up by slots 36 to form a plurality of spring legs 37 which are moulded integrally with the mounting cup 30 and which terminate in enlarged heads 38 which engage with complementary recesses 39 on a locking ring 41 also moulded from plastics material.
  • the locking ring 41 is formed with faces 42 and 43 which fit closely around faces 44 and 45 of the housing 34.
  • the face 4 ⁇ on locking ring 41 presses on face 47 of the housing 34.
  • the locking ring face 48 presses onto face 49 of the mounting cup 30 and there is an interference fit between face 48 and face 49 which causes spring legs 37 of the mounting cup to clamp locking ring 41 to housing 34.
  • the clamping action of locking ring 41 on housing 34 presses housing 34 against the gasket 31.
  • annular space 40 exists between the outer surface of housing 34 and the inner surface of the skirt 35.
  • the parts are assembled by offering locking ring 41 up to the spring legs 37 and pressing it into position. Once in position it acts to clamp the assembly together and to hold the housing 3 in sealing contact with the gasket 31.
  • the pressure exerted between the housing 34 and the gasket 31 can be adjusted by slight variations of the position of the face 46 of the locking ring 41.
  • the legs 37 are arranged symmetrically around the housing 34 and any number of legs desired may be used, adjacent legs 37 being separated by the slots 36.
  • valve components including the stem, gasket, spring and housing, are identical with that at present used in conjunction with metal mounting cups.
  • the construction shown in Figure 3 is a variation of that shown in Figure 1, the locking ring 50 being of a slightly different form and engaging the housing in a slightly different manner otherwise the construction is substantially the same and the same numerals are used to indicate the same parts.
  • the left hand insert in Figure 3 shows how the mounting cup 30 may be secured to the container by means of a screw cap 51, the mounting cup 30 being formed with a gasket 52 to engage the upper rim of the container.
  • the insert on the right hand side shows a construction in which the periphery of the mounting cup 30 is formed so as to snap over a (not shown) formed on the container.
  • Figure 4 shows a construction similar to that of Figure 2 but illustrates two different ways in which the mounting cap may be fixed to the container.
  • a gasket 60 is provided around the periphery of the cup 30 which is arranged to clamp over an annular rib 62 formed around the upper circumference of the container.
  • an annular rib 62 of the container is provided with a gasket 63 onto which the mounting cup 30 seals.
  • the mounting cup 30 is formed around its periphery with a series of spring ribs constructed to spring over the annular rib 61 or 62 as the case may be.
  • Figure 5 shows a construction that differs from the previous constructions in that the locking ring 70 is formed integrally with the housing 34 instead of separately from it; this construction reduces the number of parts used but uses a non standard valve housing.
  • the mounting cup is designed to be secured to the container by a screw cap 71.
  • any of the various forms of mounting cup and valve assembly of the invention may be secured to either a plastic, glass or metal container by any appropriate one of the various means described above.
  • the slots 36 between the spring legs 37 are used as ports for faster filling and high pressure gassing of the container.
  • the slots 36 provide an aperture through which propellent and/or actives may be introduced into the container.
  • the propellant is introduced around the valve stem 32 and flows either between the lower face of the mounting cup 30 and the gasket 31 into the annular space 40 or it flows bet;v * een the gasket 31 and the valve stem 32 and thence between the underside of the gasket 31 and the uppermost edge of the valve housing 34. From the annular space 40 the propellant flows through slots 36 into the container itself.
  • the flow of propellant around the gasket 31 into space 40 and through slots 36 allows substantially faster filling than would be the case if the propellant were all to flow through the valve housing 34 and into the container through a dip tube connected to the lower end of the housing.
