Abstract

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 relativelymovable towards one another against a restoring force which results from the inherent resilience of the unitary member.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 136 words
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 member 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.
Claim 2
Dependent Claim 136 words
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 member 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.
Claim 3
Dependent Claim 32 words
A device according to claim 1, wherein 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.
Claim 4
Dependent Claim 166 words
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 limb causing said latch to move out of engagement with the shaving unit thereby permitting ejection of said shaving unit.
Claim 5
Dependent Claim 166 words
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 limb causing said latch to move out of engagement with the shaving unit thereby permitting ejection of said shaving unit.
