Definitions

  • Figures 1-6 is intended to form either a cap, or more probably a guard surface in a safety razor blade unit having one or more elongate blades.
  • the member 1 is elongated and will be mounted on a frame of the blade unit to extend in parallel with the blades.
  • the member 1 is moulded in one piece of an elastomeric material, e.g. rubber or a thermoplastic elastomer such as that sold under the Trade Mark KRATON. It includes a rectangular base 2 from which extend upwardly, cylindrical open-topped hollow projections or tubes 3.
  • the tubes are arranged in four longitudinal rows in which the tubes 3 are equally spaced at a distance not greater than the outer diameter of the tubes, and the tubes of alternate rows are longitudinally staggered by a distance which is half the centre-to-centre pitch P of adjacent tubes in the same row.
  • tubes of adjacent rows overlap in the longitudinal direction, and as shown they also overlap in the front to rear direction.
  • the dimensions are as follows:
  • Base length - 1 30.00 mm
  • Base width - w 2.5 mm
  • Tube height-h 0.75mm
  • tubular projections are as shown in Figures 8 and 9 respectively, esxcept that in each case the outside diameter at the base is 0.75mm;
  • Figure 15 is shown a tubular projection having the same external form of the projection of Figure 14, but with a larger inner diameter at the open top end where the wall thickness is minimum and about 0.1mm;
  • the illustrated tubular projection is the same as that of Figure 10 other than that the outer diameter at the base is 0.75mm, and the inner diameter at the base is 0.55mm, the wall thickness being uniform at 0.1mm;
  • the tubular projection is similar in shape to that of Figure 11, but the diameters are reduced, the outer diameter at the base being 0.5mm, and the inner diameter increasing from 0.3mm at the base to 0.4mm at the open end, the wall thickness being constant at 0.1mm.
  • the material of the skin engaging member will have a flexibility appropriate for the particular shape and size of projections provided, but a hardness of less than 90 shore A will normally be appropriate.
