Definitions

  • ABSTRACT This invention relates to shaving devices, and more particularly to holders for shaving units of the kind in which a razor blade is secured in a permanent manner to a substantially rigid member.
  • the holder comprises ejecting means for ejecting a shaving unit from the holder when the shaving unit is to be replaced.
  • the ejecting means is a unitary member which has a latch portion adapted to secure a shaving unit in the holder, and which also has a head adapted to be brought into engagement with the rear of 'the shaving unit.
  • the latch portion and the head are relatively-movable towards one another against a restoring force which results from the inherent resilience of the unitary member.
  • This invention relates to shaving devices. More particularly the invention relates to holders for shaving units.
  • shaving unit is meant a substantially rigid member, generally of plastics material, to which one or more razor blades is secured with the rigid memberproviding a guard surface located at a pre-set spacing fromthe cutting edge of the, or each, blade.
  • a holder for a shaving unit said shaving unit consisting of a substantially rigid member to which one or more razor blades is secured with the rigid member providing a guard surface located at a pre-set spacing from the cutting edge of the, or each, blade
  • said holder comprising ejecting means for ejecting a shaving unit from said holder when the shaving unit is to be replaced, said ejecting means being a unitary member which has a latch portion adapted to secure a shaving unit in the holder, and which also has a head adapted to be brought into engagement with the rear ofa shaving unit when it is held in the holder, said latch portion and said head being relatively-movable towards one another against a restoring force which results from the inherent resilience of the unitary member.
  • the invention also provides a holder fora shaving unit, said shaving unit consisting of a substantially rigid member to which one or more razor blades is secured with the rigid member providing a guard surface located at a pre-set spacing from the cutting edge of the, or each, blade, said holder comprising ejecting means for ejecting a shaving unit from said holder when the shaving unit is to be replaced, said ejecting means having two coupled limbs, the free end of one limb being adapted to be brought into engagement with the rear of a shaving unit when it is held in the holder, and the free end of the other limb forming a latch which is adapted to secure a shaving unit in the holder, the application of pressure to the rear of the shaving unit by the free end of said one limb causing said latch to move out of engagement with the shaving unit thereby permitting ejection of said shaving unit.
  • FIG. 1 is a side view of the holder
  • FIG. 2 is a rear view of the holder
  • FIG. 3 is a mid-sectional view of the side of the holder opposite to that shown in FIG. I, and with a razor blade in position,
  • FIG. 4 is a side view of the ejector member on an enlarged scale
  • FIG. 5 is an end view of the ejector member
  • FIG. 6 is a section on the line VIVI in FIG. 2,
  • FIG. 7 is a section on the line VII-VII in FIG. 2, and
  • FIG. 8 is a section of the line VIII-VIII in FIG. 3.
  • this construction of holder is designed to hold a razor blade 11 (FIG. 3) secured in a permanent manner to a substantially rigid member 10 of plastics material, a guard surface 10a being located at pre-set spacing from the cutting edge 11a of the blade 11.
  • the rigid member 10 is located in a holder 12, assembled from a front 13 and back 14, between jaws 14a, 14b, formed integrally with the holder back 14.
  • the rigid member I button 15b which projects through an aperture MC in the holder back 14.
  • razor blades of the kind described Prior to use, razor blades of the kind described are normally stored in a container with the rear edge of the rigid member accessible. To pick up a new razor blade from the container the opening between the jaws 14a, 14b is presented to the rear edge of the rigid member 10 and the initial contact of the underside of the rigid member 10 with the latch portion 15a causes the latter to be depressed until the aperture 10b comes opposite the latch portion 15a when the latch rises into engagement with the aperture 10b to retain the rigid member 10 between the jaws 14a, 14b so that the razor blade is securely held in the holder and can be removed from the container.
  • the front 13 and back 14 of the holder are both plastic mouldings.
  • projections 13a are provided at each end of the upper surface of the front 13 to engage in corresponding recesses 14d in the underside of the jaw 14b.
  • recesses Me in longitudinal webs 14f on the inner face of the back 14 engage corresponding projections 13b on the inner face of the front 13 to provide longitudinal location between the front 13 and back 14.
  • a downwardly extending tongue 14g (FIG. 3) is provided at the lower end of the back 14 facing inwardly, to secure the front 13 and back 14 together before they are bonded by appropriate means, for example by ultrasonic welding.
  • a metal weight 16 may be housed within the holder 12 to give a desired balance and feel.
  • a shaving device including a holder and a shaving unit, said shaving unit consisting of a substantially rigid member to which at least one razor blade is secured with the rigid member having a guard surface located at a pre-set spacing from the cutting edge of the blade,
  • said holder including ejecting means for ejecting a shaving unit from said holder when'the shaving unit is to be replaced, said ejecting means being a unitary member having a latch portion for securing said shaving unit in the holder, said unitary mem ber further having a head for engagement with the rear of said shaving unit when it is held in the holder, said latch portion and said head being relatively-movable toward one another against a restoring force which results from the inherent resilience of the unitary member.
  • said ejecting means carries an ejector button by which pressure is applied, via said head, to the rear of the shaving unit to be ejected.
  • a shaving device including a holder and a shaving unit, said shaving unit consisting of a substantially rigid member to which at least one razor blade is secured with the rigid member having a guard surface located at a pre-set spacing from the cutting edge of the blade,
  • said holder including ejecting means for ejecting a shaving unit from said holder when the shaving unit is to be replaced, said ejecting means having two coupled limbs, the free end of one limb carries an ejector button by which pressure is applied, via the free end of said one limb, to the rear of the shaving 'unit to be ejected, and the free end of the other limb forming a latch which secures said shaving unit in the holder, the application of pressure to the rear of the shaving unit by the free end of said one
