<p>The disposable razor for wet shaving has a rod handle (1) with rupture points (2-7) at regular longitudinal intervals. These enable the user to record the number of times a particular razor has been used i.e. after each shave the handle is ruptured at the point nearest the free end. The number of rupture points remaining, thus indicates the number of remaining shaves. The rupture points are defined by a geometric figure in relief on the handle. The figure may be a circle and the material contained by the circle is of a lesser thickness than the body of the handle. The centre of each circle (2-7) may alternatively be defined by a press-stud (8), and each stud may be fixed to the handle by a membrane or radial spars.</p> |
