ABSTRACT:
An all in one disposable razor assembly comprising a hollow-shafted handle having a blade-attached razor head at a first end and an opening at a second, opposite end of the handle. The handle includes a central cavity therein with an elongated cavity lip disposed outside adjacent the open end of the hollow handle to receive a reservoir of stabilized shaving material in an amount sufficient for a single use. The cavity has disposed therein a dispensing assembly comprising a piston head and an attached towing cable for manually forcing the shaving material out of the hollow handle through the open end. In the preferred embodiment, the dispensing assembly includes a cap, initially attached to the elongated lip but easily releasable therefrom by pulling on an attached tear-away tab. Dispensing the shaving material is performed by releasing the cap and pulling the towing cable out of the cavity thereby moving the piston head from the blade-attached end to the open end, forcing the shaving material from the cavity into the user's hand. The cap is preferably attached by heat wherein the outer circumference of the cap is thermally back-welded to the underside of the cavity lip. An alternate embodiment provides for a reusable razor and shaving assembly wherein individual refill cartridges, each of which contains the above mentioned dispensing assembly and shaving material, may be repetitively inserted in the cavity of the handle.
