Definitions

  • This invention relates to a cosmetics package.
  • One general type of solid cosmetics product including facial blushers, eye shadow etc., has traditionally been made by compressing a quantity of coloured powder into a tablet or brick which is then mounted inside an appropriately shaped case.
  • volatile silicones such as cyclomethicone
  • properties which make them suitable for use as a binder for coloured powder cosmetics materials Not only is their high volatility an advantage in promoting quick drying when applied to the face, but also they exhibit a high slip coefficient so that the material can easily be applied to the face by stroking a stick of the composition against the skin.
  • the present invention seeks to provide a package for presenting such a cosmetics colouring composition including a volatile binder, in stick form.
  • Various types of cosmetics stick packages are known, and they generally include a holder for the stick, the holder being adapted selectively to expose the stick. for use and to conceal it within a cover tube after use so as to permit a cap of the device to be replaced on the holder without damaging the stick.
  • the base of the stick may be held in a cup which can be driven axially within the cover tube by a drive mechanism responsive to relative rotation between the cover tube and a base tube, the direction of axial movement of the cup depending upon the direction of this relative rotation.
  • the present invention aims to provide a construction of a holder suitable for a cosmetics stick, the construction being capable of alleviating this problem of evaporation where the stick includes a volatile binder.
  • the invention provides a holder assembly for a stick of consumable material including a volatile constituent material, the assembly comprising a base for holding the stick and a-cap removably engageable with the base to close the assembly, sealing means being arranged to inhibit the egress from the closed assembly of vapour formed therein by evaporation of said volatile material from the cosmetics stick.
  • a holder assembly for a stick of solid consumable material including a volatile constitutent material comprising a base and a cap, the base being adapted to hold the stick, and the cap being removably engageable with the base to close the assembly, sealing means being arranged to provide a seal between the cap and the base so as to inhibit the egress from the closed assembly of vapour formed therein by evaporation of said volatile material from the cosmetics stick.
  • the sealing means is preferably provided by a sealing member made from a resiliently deformable material, e.g. a plastics material such as low-density polyethylene.
  • This sealing member may be a sealing insert fixed inside the cap so as to sealingly engage the outer surface of a tubular component of the base holder.
  • the base holder comprises an outer tube closed at one end and an inner tube disposed coaxially in the outer tube with a portion projecting axially from the open end of the outer tube, these two tubes being relatively rotatable to cause a stick holder element to move axially within the inner tube to advance and retract the cosmetics stick. In the retracted position, the stick is accommodated wholly within the inner tube.
  • the sealing member is preferably a cap shaped insert located inside the cap at the closed end thereof and shaped so as to fit over and seal against the end of the inner tube of the base holder.
  • This cap insert preferably has a cylindrical body portion, the inside cylindrical surface of which is formed with one or more annular inwardly projecting sealing beads dimensioned to form a tight-fit on the outer cylindrical surface of the inner tube.
  • the above arrangement inhibits the egress of vapor from the stick out of the open end of the inner tube and toward the exterior between the cap and the inner tube.
  • Another possible route for the egress of the vapour is in the opposite direction from the stick through a gap between the stick holder element and the inner tube toward the base end of the outer tube, and thence to the exterior through whatever minute air gaps there may be by virtue of the relative rotational arrangement of the inner and outer tubes.
  • the invention aims to inhibit vapour loss via this route and to that end provides a holder assembly for a stick of a solid consumable material including a volatile constituent material, the assembly comprising an elongate hollow base member which is open at one end, a cap adapted to fit over said open end of said base member to close the assembly, an element disposed within said base member for carrying a said stick, and a mechanism responsive to relative movement of first and second parts of said base member for driving said carrying element axially within said base member between a first position in which the stick projects from said open end, and a second position in which the stick is at least partly retracted within said base member, and sealing means providing a seal between said carrying element and said base member so as to inhibit egress of vapoour formed by evaporation of said volatile material from the cosmetics stick into a space within the base tube from which it could escape through a gap or gaps between said first and second parts.
  • the base member may comprise an outer tube closed at one end and an inner tube disposed coaxially and rotatably within the outer tube, the stick carrying element being arranged to move axially within the inner tube.
  • This stick carrying element may be in the form of a cylindrical cup in which the base portion of the stick may be affixed, this cup again being made of a suitable plastics material and formed with an annular outwardly projecting bead constituting the sealing means, said bead engaging against the inner cylindrical surface of the inner tube.
  • this bead can again be resiliently deformable to provide the required seal.
  • a holder assembly for a cosmetics stick includes both of the sealing means defined above in accordance with the two particular aspects of the invention.
  • the cosmetics stick device comprises a base part 1, and a cap 2 which can be removably attached the base part.
  • the base part includes a cylindrical base tube 3 which is closed at its lower end 4 and open at its opposite end.
  • a cylindrical inner tube 5 Accommodated partly within this base tube 4 is a cylindrical inner tube 5 which is open at both ends.
  • This inner tube extends inwardly of the base tube from its open end to a position about half way along the length of the base tube, and has a substantial portion 6 which projects outwardly of the base tube.
  • the inner tube is rotatable relative to the base tube.
  • a generally tubular retainer ferrule 7 is rigidly fixed to the base tube and includes various portions performing different functions.
  • a part of the ferrule projects outwardly from the open end of the base tube 1 and comprises an annular stop 8 which abuts against the end of the base tube to define the required axial positioning of the ferrule relative to the base tube, and a generally cylindrical cap retaining portion 9 formed with a plurality of circumferentially spaced engagement bumps 10 to engage the inner surface of the cap so as to retain the cap in its closed position.
  • bumps 10 can be formed by simply outwardly deforming the wall of the cylindrical portion 9 slightly at an appropriate number of circumferentially spaced positions.
  • the outer end 11 of the ferrule is of slightly reduced diameter to define an opening through which the inner tube 5 projects.
  • the part of the ferrule 7 within the base tube 4 includes a reduced diameter portion 12 adjacent to the annular stop 8, and from this portion 12, the ferrule widens to an elongate cylindrical engagement portion 13 which is a tight-fit within the base tube so as to retain the ferrule fixed thereto. From this portion 13, the ferrule narrows slightly to a cylindrical base portion 14 the inner end of which is turned inwardly to form a radially inwardly projecting flange 15. This inner portion 14 accommodates and fixes one element of a screw advance mechanism to be described below.
  • the cap 2 comprises a cylinder of the same outer diameter as that of the outer tube 5 of the base portion, and is closed at its outer end.
  • a cosmetics stick holding element 16 Disposed coaxially within the inner tube there is a cosmetics stick holding element 16 which is arranged to be driven axially so as to cause a cosmetics stick 17 shown in dashed lines in Figure 1 to be projected from and retracted within the inner tube 5.
  • This stick holding element 16 comprises a generally cylindrical cup portion 18 for holding the cylindrical base portion of the cosmetics stick 17 and a rearwardly extending screw shaft 19 which extends axially within the base part 1.
  • this screw shaft is generally of flat configuration having two opposite elongate flat surfaces 20 and two opposite part- cylindrical surfaces 21 formed with flight portions defining a screw thread.
  • a cylindrical guide member 22 Fixed within the inner end of the inner tube 5 is a cylindrical guide member 22 having at its forward end a wall defining a guide slot 23 through which the shaft 19 may freely move in an axial direction. However, because the shaft 19 cannot rotate in the slot 23, the stick holding element 16 is restrained from rotating relative to the guide 22 and thereby also relative to the inner tube 5.
  • a screw driving member 24 comprises a forward driving portion 25 and a rear fixing portion 26.
  • the forward driving portion 25 is disposed within the guide tube 22 and is located axially by engagement of an inwardly projecting annular rib 27 on the inner surface of the guide member 22 in a complimentary annular groove 28 formed at the rear end of the drive portion 25.
  • the fit between the guide 22 and the drive portion 25 of the driving member 24 is such as to permit relative rotation between these parts, with the rib 27 rotationally sliding in the groove 28.
  • the drive portion 25 is formed internally with a helical screw thread which meshes with the screw thread on the screw shaft 19.
  • the retaining portion 26 of the driving member 24 is firmly fixed in the cylindrical base portion 14 of the retainer ferrule 7.
  • the components forming the screw advance mechanism namely the stick-holding element 16, guide member 22 and driving member 24, are preferably made of a suitable plastics material such as polyacetal or high density polyethylene providing a smooth screw-advance operation.
  • a suitable plastics material such as polyacetal or high density polyethylene providing a smooth screw-advance operation.
  • the inner cylindrical surface of the cup 18 is preferably formed with a set of circumferentially spaced axially extending and inwardly projecting ribs 29 and a ring of circumferentially spaced and extending ribs 30. These ribs 29 and 30 penetrate into the outer surface of the stick 17 and serve to hold the stick 17 firmly in the cup 18.
  • the device is provided with sealing means to inhibit the egress of vapour formed by evaporation of a volatile binder material used as a constituent in the making of the stick 17.
  • sealing means to inhibit the egress of vapour formed by evaporation of a volatile binder material used as a constituent in the making of the stick 17.
  • there are two such sealing means the first comprising a sealing cap 31 fixedly disposed in the end of the cap 2.
  • This sealing cap is shown in greater detail in Figure 3.
  • the cap 31 is generally cylindrical and closed at its upper end except for a small exhaust aperture 32 which is necessary to permit full insertion into the outer cap 2.
  • the sealing cap is made of a suitable flexible plastics material, e.g.
  • the generally cylindrical wall of the cap 31 includes an end portion 34 which tapers to a very small thickness at the edge 35. This tapered portion facilitates smooth entry of the outer end of the inner tube 5 into the sealing cap 21 when the cap 2 is placed on the base part 1.
  • the other means provided in this embodiment for inhibiting vapour egress and thereby minimising loss of binder from the cosmetics stick provides a seal between the cup 18 of the stick holding member and the inner tube 5 in which such member axially moves.
  • This seal is provided by an outwardly extending circumferential bead 41 formed on the outer cylindrical surface of the cup 18.
  • This bead is formed so as to have an outer diameter which prior to assembly is very slightly larger than the inner diameter of the inner tube 5. Accordingly, when the cup is inserted into the inner tube during assembly of the device, this bead 41 becomes slightly compressed so as to form an efficient seal with the tube 5.
  • the two sealing means comprising the sealing cap 31 and the bead 41 on the cup 18 serve to define in the closed position of Figure 1, a substantially sealed space which is little greater in volume than the space actually occupied by the cosmetics stick 17. Accordingly, only a small amount of evaporation of the binder material from the cosmetics stick 17 will occur, and the vapour so produced is substantially inhibited from escaping from this space, so in turn inhibiting further evaporation.
  • the present invention also embraces any other novel aspects of the device.
