Definitions

  • the invention relates to a device for removing a composition from the skin and to a method for such removal.
  • the invention relates in particular but not exclusively, to a device for use in a depilatory method.
  • Depilatory compositions are widely available. The user applies such compositions to their skin, leaves them for a predetermined interval to allow them to work and then removes them from the skin, usually using an article which is provided. This is typically a cloth or sponge or elastically flexible plastics sheet having a linear removal head .
  • Such a sheet is inevitably not optimal for all parts of the body, in particular for parts which are sharp in their curvature, such as the ankle or armpit.
  • the user will normally, perhaps unintentionally, alter the angle that they hold such a sheet at and thereby alter the removal effect of the sheet disadvantageously . This is particularly the case, for instance, as the user moves the sheet up the leg, from the ankle region towards the knee.
  • a device for removing a composition from the skin comprising a handle connected to a head which, in use, is moved over the skin to effect removal of the composition, the head including at least two fins which project from a curved portion of the head.
  • the head has at least three fins which project from a curved portion of the head.
  • a device for removing composition from the skin comprises a handle connected to a head which, in use, is moved over the skin to effect removal of composition, the head including at least three fins each having a free edge, the included angle between a line extending from a first free edge to an adjacent second free edge and the line from the second free edge to an adjacent third free edge on the other side of the second free edge to that of the first free edge being less than 180°.

  • Each of the fins may extend in a radial direction which radii, when extended inwardly, meet at a common axis.
  • At least one fin may be flexible.
  • each of the fins is flexible.
  • flexible we mean that when in contact with the skin and being moved forwards it is deflected to a substantial degree in the rearwards direction. On being removed from the skin it recovers its initial position.
  • the fins may be of a plastics material which has elastic properties but preferably the fins are of an elastomeric material .
  • the fins may extend from a base, which may be flexible.
  • the base may be of a plastics material which has elastic properties but is preferably of an elastomeric material.
  • the base and the fins may be integral . Preferably they are integrally moulded. At least one fin may be integral with the base.
  • the device may include a base having an arcuate outer surface and the fins may extend radially from the base. This arrangement may also be employed in the second embodiment .

  • the radius of such a free edge is up to 1.5mm, more preferably up to 1mm, and most preferably up to 0.85mm. It may be a compound radius, for example having a major radius in accordance with the definitions given above and a minor radius, smaller than the major radius, at the distal tip of the free edge.
  • such a minor radius is up to 0.5mm, more preferably up to 0.3mm, most preferably less than 0.25mm.

  • the device 2 includes a handle 6 arranged to be gripped by a user with the thumb projecting forwardly and located against a slanted thumb locator 8.
  • the proximal end of the handle has an extension 10 beyond the thumb locator 8.
  • the handle 6, via its extension 10, and the head 4 meet at a flexible hinge 12.
  • the device is partly moulded from a plastics material, including parts of the handle 6, hinge 12 and head 4. Also integrally moulded with these parts is an elastomeric material (hereinafter called rubber) . The rubber regions are shown shaded at 16.
  • the plastics material adjacent to the hinge 12 is moulded into a valley 17 facing downwards between two valleys 18 facing upwards, in the shape of a "W" .
  • the "W" itself is of the plastics material and the valleys contain rubber. In this way the head is also able to pivot relative to the handle in the region of the valley with the pivoting being resisted and ultimately limited by the compression of the rubber 16 in the valleys .
  • the head 4 includes six fins 20, of the rubber.
  • the fins are not parallel to each other.
  • the free edges are parallel but non-coplanar.
  • the free edges of fins are each of about 35mm length.
  • the plane of each fin projects radially from an arcuate section 22 of the head, with that section also being of rubber.
  • the fins are not made of flexible material but are instead made of a flexible plastics material.
  • the head comprises a curved base.
  • the fins issue from the base, in a closely spaced and slightly splayed array.
  • the base has a lower supporting region 24 of the plastics material, and the arcuate rubber section above it, from which the fins project.
  • the included angle as defined above is about 160°.
  • depilatory composition for instance in the form of a cream, gel, lotion or foam, is applied to the skin.
  • the composition is left on the skin for a predetermined time of, for instance, 3 to 5 minutes. During this time, hairs on the body become detached or weakened as a result of the action of the depilatory composition.
  • Removal of the composition and entrained hairs is achieved by a user holding the handle 6 and applying a force to urge the head against the skin.
  • the head may flex about the hinge 12 and, to some extent (especially when the head can flex no further) about the junction 26 between the thumb locator 8 and the extension 10.
  • the handle is inclined away from the body in the direction 28 that the device is then moved in.
  • fins will often contact the skin at any one time but this is possible when the body part contacted is concave, or soft, or when a sufficient force is applied by the user. More commonly one or two fins, typically leading fins, will be spaced from the body to clear the composition to a certain extent. A downstream fin, or fins, will be in contact with the skin, and this will effect a scraping action which breaks off hairs that have become weakened but not yet detached.
  • the base of adjacent fins are approximately 3mm from each other.
  • Each fin is approximately 3mm in height from the base with each fin being about 1mm thick (or in other embodiments in which they taper from base to free edge, the mean thickness may be about 1mm) .
  • the free edges of the fins may be radiused.
  • the leading fin may have a removal effect, as may the second and third fins, for instance, when the distal end of the handle is closer to the skin.
  • the trailing fins may effect removal.
  • the leading fins may remove composition but without effecting scraping. It can be seen that more or fewer fins may effect scraping or composition removal only depending upon the angle of the handle and, alternatively or additionally, the pressure applied to the head by the user.
