  • sideways pressure on the brush which will be common during use, will deform the rim (2120), thereby separating it from the secondary body (2200) and allowing the secondary body (2200) to slide free of the main body (2100).
  • the brush has two pluralities of bristles, one plurality com rising a comb with stiff bristles (1122), the bristles either substantially rigid or semi-rigid, and one plurality comprising a brush (1110), with the bristles substantially flexible, and is bu ilt around a one-piece chassis (not shown) of heat-resistant material, which has a head portion (1100) and a handle portion (1200). At least the head portion (1100) of the chassis and, preferably, the handle portion (1200) of the chassis are substantially completely covered with a silicone coating; the silicone coating on the handle providing a "soft-touch" handle which is comfortable to use.
  • the stiff bristles (1122) of the comb are part of a comb unit (1120), which comprises a back portion (1124) with a rear side and a front side in which the st iff bristles (1122) extend from the front side and the rear side is mountable to the head portion (1100) of the chassis.
