Definitions

  • This invention relates to indicator means whereby a record of usage of a disposable safety razor is maintained on the razor handle.
  • Disposable safety razors in which one or more blades are moulded integrally into the blade holder of a unitary razor design of plastic construction, have largely displaced the earlier metal razor in which single or double-edged blades were replaceable upon having lost their keen edge consequent to usage.
  • safety razor blades can be used for between 7 and 10 or 12 successive shaves, depending on conditions of usage, whereupon the razor is discarded, the cost of the handle and blade holder being nominal in comparison to the cost of the blade.
  • U.S. Patent No. 4,208,984 discloses a slidable use indicator operating in a longitudinal slot in the handle, with a pointer on the slide registering with indicia in the handle;
  • U.S. Patent No. 4,268,958 describes a use indicator in which a number of frangible plastic tabs extend outwardly from the handle, intended to be broken off following use,
  • Rotatable counters have been proposed, as in U.S. Patent Nos. 5,119,557 and 3,229,659, which are rotatable relative to the handle. Each of these designs have failed to meet the requirements of no increase of manufacturing, and no significant complexity of use to the user.
  • a disposable safety razor with usage indicator means formed integrally in the handle comprising pressure- sensitive marker elements is provided which avoids prior art deficiencies.
  • the usage indicator means of the present invention may be readily incorporated into current razor designs without significant manufacturing retooling.
  • the usage indicating means comprises a plurality of deformable bubble indicators embodied in linear array on the handle.
  • the user exerts pressure with the thumb or finger, thereby deforming the bubble into visibly identifiable register condition, thereby to record a single use of the blade.
  • the method and device of the present invention thus provides the user with ready visual means of recording usage, without further reference to any record other than the razor itself.
  • the number of shaves remaining is readily ascertainable before each use, and prior to any otherwise uncomfort ⁇ able shaves resulting from use of an overused, dull blade.
  • Figure 1 is a perspective view of the device of the preferred embodi ⁇ ment, with the usage indicators in linear array on the handle.
  • Figure 2 is a cross-section taken at 2.2 of Figure 1 , indicating the relative thickness of the plastic in the handle parts.
  • Figure 3 illustrates the razor of Figure 1 after partial use.
  • a disposable razor 10 formed of moulded plastic includes a hollow moulded plastic handle 11, normally open at the bottom end 12, of longitudinally extending configuration and generally rectangular in cross-section as depicted in Figure 2.
  • a blade holder 13 adapts to hold a blade 14, and is integrally formed with the handle 11 at its upper end 15.
  • Hemispherical bubbles 16 are integrally moulded into the handle 11 and protruding outwardly therefrom, as depicted; having a skin thickness such that they are readily distendable into the hollow interior of the handle, while retaining their configuration under normal conditions of use. It will be apparent that, alternatively, the plastic bubbles may be so designed as to be breakable under finger pressure, thereby also leaving a readily visible marker on the handle.
  • the bubbles 16 are formed in extended linear serial array on one side of the handle 11 as depicted, thereby to form a readily accessible indexing means for registering usage of the razor.
