Definitions

  • the invention relates to roll-on dispensing devices for use in applying viscous fluids to the body and to methods of removing body hair by means of depilatories.
  • US Patent 4002411 (Harbauer) describes a ball type applicator for deodorants, perfumes or similar cosmetics comprising a container with an externally threaded neck portion, a ball retaining fitment attached to the neck portion, and having on its lower part a plurality of inwardly extending flanges on which the ball seats, the flanges being in the shape of a right triangle with the ball resting on the hypotenuse of the triangle.
  • the upper part of the ball retaining fitment tapers inwardly and its diameter is smaller than the diameter of the ball, which is free to move between the tapered top of the fitment and the flanges.
  • the container is closed by a dome shaped cap, the interior of which has a downwardly depending deformable sealing ring, which makes sealing contact with the rim at the top of the ball-retaining fitment when the cap is screwed on the neck of the container.
  • a dome shaped cap the interior of which has a downwardly depending deformable sealing ring, which makes sealing contact with the rim at the top of the ball-retaining fitment when the cap is screwed on the neck of the container.
  • the cap When the cap is screwed in place its interior also engages the ball to make a second seal.
  • US Patent 3752155 (Blinoff) concerns apparatus for heating or cooling the skin surface while simultaneously dispensing a liquid product thereon.
  • a ball type applicator in which the ball acts as a heat exchange element is used.
  • a container for the liquid to be dispensed is provided with a retainer member for the ball at its outlet end.
  • the retainer member has a concave slightly resilient baffle, with a projection at its base and on which the ball rests.
  • the ball is retained in place by a ring which is slightly larger at its lower side than the ball diameter but slightly smaller at its upperside than the ball diameter or provided with a plurality of symmetrically arranged lugs which slidably engage the ball exterior.
  • the concave baffle is adapted to receive and retain liquid from the main container through holes in its sides thereby acting as a reservoir from which the ball dispenses the liquid.
  • the apparatus is provided with heating arrangements for the ball so that warmed fluid can be dispensed.
  • the ball dispenser can be closed by a cap which exerts a downward force on the ball which distorts the baffle and makes seal with the upper part of the concave baffle to seal the container.
  • the invention provides a roll-on dispensing device for a viscous fluid of the kind comprising a ball rotatably mounted in a housing which provides an inlet and an outlet for fluid dispensed by rotation of the ball, wherein the housing is provided with a plurality of arcuate projections extending from the inlet side to the outlet side of the housing, serving to support the ball and to retain the ball in place, said projections having spaces in between through which fluid can be fed by rotation of the ball and the roll-on device is specially adapted to dispense depilatory fluid.
  • the arcuate projections comprise radially inwardly protruding ribs formed in the housing and extending axially from the inlet side to the outlet side of the housing and the radially inner edges of the ribs jointly define a zone of a sphere.
  • the ball is a substantially smooth sphere.
  • the device is provided with a cap, the cap having therein a head space above the ball, which permits the ball to be bathed with fluid when the device is shaken.
  • the housing is preferably provided with a bevelled edge and the cap is provided with an internal rim or ledge which mates with said bevelled edge to provide a liquid tight seal.
  • the invention also provides a method of removing body hair which comprises applying to an area of the body a depilatory fluid by means of a roll-on device specially adapted to dispense depilatory fluid, allowing said fluid to react with the hair for a sufficient period of time, removing the loosened hair and rinsing the body area.
  • the method is especially useful for removal of hair from the armpits.
  • the depilatory fluid is usually allowed to react with the hair for up to 10 minutes, e.g. 1-10 minutes or up to 5 minutes may be sufficient.
  • the method may be carried out by a ball rotatably mounted in a cavity in a housing which provides an inlet and an outlet for fluid dispensed by rotation of the ball, wherein either the ball or the housing is provided with radial protrusions the radial extremities of which define a spherical surface and the other of the ball and the housing has a spherically curved surface for rolling engagement with the extremities of the protrusions, the protrusions operating as radial spacers forming spaces through which fluid can be fed by rotation of the ball.
  • the ball may be formed with a multiplicity of radially outwardly projecting protrusions, the radially outer extremities of which define a sphere and engage the surface of said cavity, which is smoothly spherically curved.
  • the roll-on device is of the type described herein.
  • the housing may be formed integrally with the neck of the container for the depilatory, or it may be a separate unit which is located at the neck of the container or it may even form the neck of the container.
  • the housing may have internal screw threads or other means for attachment to the body of the container, such as a groove for mating with a corresponding rib on the body of the container.
  • the housing for the ball is made of a relatively resilient plastics material such as polyethylene and is designed so that the ball can be pushed into place by slight deformation of the walls of the housing which then spring back into shape thereby gripping the ball.
  • the device comprises a container body 1, which may be made of moulded polyvinyl chloride, a housing 2, a ball 3, and a cap 4.
  • the container body 1 has screw threads 5 for attachment of cap 4 by corresponding screw threads 6.
  • the container body 1 has a circumferential rib 7 for attachment of housing 2 by a co-operating circumferential groove 8.
  • the housing 2 is made of polyethylene and is pressed over rib 7 to provide a snap fit thereby producing the neck of the container.
  • the housing 2 has a series of equispaced projections 9 of arcuate shape (Fig. 2a). When in position the ball 3 sits on the base of arcuate projections 9 and is held in position by the arcuate shape of the projections 9.
  • the housing 2 has a bevelled edge 10 at the top which mates with a corresponding rim 13 on cap 4.
  • the housing 2 is fitted on to body 1 by snap fit of groove 8 over circumferential rib 7.
  • the ball 3 has a diameter slightly greater than the circle provided by the tops of projections 9 (Fig. 2b) and is pushed into the housing through the tops of the resiliently deformable projections 9, until it rests snugly in the housing held by the arcuate projections 9.
  • the ball can rotate freely on the seat provided by the bases 9a of these projections yet is held firmly by them in view of the curve of the upper parts 9b of the projections.
  • the cap 4 is screwed on to container body 1, enveloping the neck produced by housing 2.
  • the bevelled edge 10 and rim or ledge 13 provide a liquid tight seal.
  • the cap has another internal ledge 16, which abuts the ledge 15 of band 17 of the housing.
  • the body 1 may carry labelling on the flat portion 14 of its side or sides.
  • the container body 1 may be filled with a thixotropic depilatory lotion formulation such as one described in Harry's Cosmeticology, published by Leonard Hill Books, 6th Edition 1976.
  • the cap In use the cap is removed and the device is used to apply depilatory to the armpits or other body area. Before removal of the cap it is usually desirable to shake the container to ensure sufficient depilatory is covering the upper surface of the ball. This assists initial application of the depilatory.
  • the headspace 18 is sufficient to enable depilatory lotion to bathe upper surface of ball 3 when the device is shaken with the cap on.
  • a device of the type described was tested against a standard pack of the roll-on deodorant type and a depilatory spray.
  • a roll-on dispensing device comprising a ball 20 held captive, but rotatably mounted, in a housing 21 providing a snap-on fitment 22 by which the housing can be secured to the mouth of a container for a viscous fluid.
  • the ball is a smooth sphere, but the cavity 23 in which the ball is held captive has a plurality of radially-inwardly extending ribs 24 whose radially inner edges together define a spherical surface supporting the ball for rotation and holding it captive.
  • Five ribs 24 are provided in the illustrated construction. The ribs 24 space the ball 20 from the cavity wall and enable a thick film of fluid to be carried by the ball in the areas between the ribs 24. This construction has been found to be particularly useful in dispensing thixotropic substances.
  • a ball 30 for a roll-on dispenser which has a multiplicity of radial protrusions 31. These protrusions have flat tops which together define a sphere. Such a ball is rotatably mounted in and held captive in a cavity in a housing of the known kind.
  • the protrusions 31 act as spacers to accommodate between the spherical surface of the ball and the smooth spherically-curved wall of the cavity a relatively thick film of the fluid to be dispensed. This construction has been found particularly useful in dealing with fluids which tend to lubricate the ball to such an extent that a smooth ball glides over the surface without rotating.
  • the protrusions on the ball 30 produce a frictional driving effect on the ball when it is moved across the surface.
  • a sealing cover is placed over the ball and housing.
  • the ball preferably has a diameter of at least 25 mm.
  • the devices of the invention may also be used to apply viscous liquids, especially thixotropic liquids, cream or powder formulations, including topical pharmaceutical formulations, to other parts of the body besides the armpits.
