DESCRIPTION:
BRIEF SUMMARY
This invention relates to shaving systems, that is systems of the general form now in widespread use comprising a razor handle and a plurality of razor cartridges housed in a dispensing container from which they can be picked up one at a time by the handle and moved out of the container for use.
In some systems, the handle and cartridges have simple fixed slide structures for mutual engagement, but the present invention is particularly concerned with systems in which the handle has an operating mechanism comprising latch means which are manually operable for engagement and disengagement of the cartridges, and aims at the provision of such a system in which the manipulation required to engage a cartridge is greatly simplified.
The invention provides such a system in which the user merely has to pass the razor head through guide means provided in the dispenser in order to pick up a cartridge and, as an optional preliminary, to deposit a used cartridge in the container.
More particularly, the invention provides a shaving system comprising a razor handle, a plurality of exchangeable blade cartridges and a dispensing container housing a plurality of the cartridges, the handle being provided with a pair of arms for engaging and disengaging cartridges with and from the handle, wherein the container houses a plurality of cartridges side-by-side and is formed with a guide means extending longitudinally of the container, transverse to the lengths of the cartridges, from one, entry end to the opposite, exit end of the container, the arrangement being such that the razor handle can be engaged in the container at the entry end thereof, and moved along the length of the container, clear of the cartridges, except for the last cartridge nearest the exit end with which it is brought into operative engagement, the guide means cooperating with the said arms to move them into a disengaged condition until the handle reaches the last cartridge, whereat the arms are returned to their operative positions to engage the last cartridge.
One form of system in accordance with the invention will now be described in detail, by way of example, with reference to the accompanying drawings, in which:
FIG. 1 is a top plan view of the system;
FIGS. 2, 3 and 4 are longitudinal sections, showing the container full of cartridges and a razor handle in successive operative position along the container; and
FIGS. 5, 6 and 7 are cross-sections taken at the lines V--V, VI--VI and VII--VII, respectively in FIG. 1.
In the shaving system illustrated in the drawings, the razor handle H and cartridges C have the general form described and illustrated in U.S. Pat. No. 4492025 and International Publication Number WO 85/01466, to which reference is hereby directed, and relevant parts of the razor and cartridge are given the same reference numerals as in the said U.S. Publication. In particular, the razor comprises a grip portion 72, cartridge engaging arms 78, 80 and a spring loaded plunger 104 having a free end portion 106. The arms 78, 80 are operable to disengage a cartridge by pressing them inwardly towards each other against a resilient restoring force. The plunger 104 acts as a releasable locking means which locks the arms 78, 80 in their disengaged position.
The cartridges each have depending extensions which are engageable by the arms 78, 80 to secure the cartridge in operative engagement with the handle, and concave cam surfaces for engagement by the free end 106 of plunger 104.
The above described razor handle and cartridges were designed for manual operation for engaging and disengaging cartridges. Assuming a used cartridge to be in position on the handle, the user presses in the arms 78, 80 to disengage the arms from the extensions to release the cartridge. To engage a new cartridge, the user brings the head of the handle into engagement with the underside of the cartridge, thereby depressing the plunger 104 to trigger release of the arms, which spring out to engage the new cartridge in its operative position.
