Razors

Abstract

Razor handles are provided for razors having a battery-powered functionality. Methods of manufacturing such handles are also provided. In one implementation, the handle includes a unitary grip portion constructed to receive a razor head at one end thereof, and a battery cover, mounted on the grip portion. The grip portion and the battery cover, when joined, may together define a water-tight unit prior to mounting of the razor head on the grip portion.

1 . A method of manufacturing a razor handle, comprising:
 forming a unitary grip tube having a closed end configured to receive a razor head;   inserting a battery and a carrier into an open opposite end of the grip tube, the carrier having electronic components mounted thereon;   sealing the open end of the grip tube; and   testing the electronic functionality of the resulting assembly.   
     
     
         2 . The method of  claim 1  further comprising mounting a razor head on the closed end if the testing step results in a determination that the electronics are functional. 
     
     
         3 . The method of  claim 1  wherein the sealing step comprises mounting a removable battery cover on the open end. 
     
     
         4 . The method of  claim 3  wherein mounting the battery cover on the open end renders the assembly water-tight. 
     
     
         5 . The method of  claim 2  wherein the mounting step comprises fixedly mounting the razor head. 
     
     
         6 . The method of  claim 2  wherein the razor head is configured to receive a disposable razor cartridge. 
     
     
         7 . The method of  claim 1  wherein forming the unitary grip tube comprises molding a grip tube preform having a window opening and welding a window into the opening. 
     
     
         8 . A method of forming a plurality of razor products having a battery-powered functionality, the method comprising:
 forming a plurality of substantially identical razor sub-assemblies, each sub-assembly including (a) a unitary grip tube having a closed end configured to receive a razor head, and (b) a battery and battery-powered components disposed within the grip tube, the grip tube being sealed in a water-tight manner; and mounting a first razor head on the closed ends of a first sub-set of the razor sub-assemblies to form a first product, and mounting a second, different razor head on the closed ends of a second sub-set of the razor sub-assemblies to form a second, different product.
