Definitions

  • This invention relates to wet shave razors and, in particular, to wet shave razors having a die cast top frame with an integral weight and stiffener.
  • Most commercially available wet shave razors consist of at least five separate components. These components include the razor head which, in the case of a permanent system is used to attach a razor cartridge and in the case of a disposable system includes the cartridge, two half shells of the handle, a weight, and a top frame which covers the razor head. During manufacturing, the two half shells are fitted together surrounding the weight and the top frame is placed such that it covers the razor head. The end result is a razor unit which requires a maximum number of parts and significant assembly, resulting in greater difficulty and expense to the razor manufacturer.
  • a razor unit has a member comprising a top frame with an integral weight.
  • the portion of the member which acts as the integral weight is contained within the hollow shell of a razor handle while the top frame portion protrudes beyond one end of the handle to provide a decorative cover for a razor cartridge or an attachment means for a razor cartridge.
  • the integral member reduces the overall number of parts of the razor, reduces the assembly time and provides a stiffening member to the razor handle. Further, the integral member provides proper weight and balance to aid in obtaining a comfortable shave.
  • Figure 1 is an exploded view of a razor unit containing the top frame with the integral member.
  • Figure 2 is a cut-away top view of a razor unit containing the top frame with the integral member.
  • Figure 3 is a side cut-away view along line A-A of Figure 2.
  • wet shave razors are defined to be razors which are customarily utilized in conjunction with soap or shaving cream and hot water.
  • the definition of wet shave razors includes both disposable razors, in which the user discards the entire unit after a certain number of uses, and permanent systems, with which the user discards and replaces the razor cartridge after a certain number of uses.
  • the razor head, or cartridge is the portion which surrounds and contains the blade or blades.
  • the combination of the razor head and the handle, either permanent or disposable, is defined as the razor system.
  • the present invention provides for a wet shave razor system which comprises a razor handle consisting of an upper shell and a lower shell and a top frame having an integral weight member.
  • a razor handle consisting of an upper shell and a lower shell and a top frame having an integral weight member.
  • top shell 15 and bottom shell 16 surround the integral weight member 10 in the razor system.
  • the razor handle may be a hollow, one-piece unit which surrounds the integral weight member.
  • the integral weight member 10 comprises interior weight section 11 which is contained within the handle, transition section 13 (surrounded by the circle in Figures 1 and 2) which protrudes through opening 21 in the top shell and top frame 12 which extends externally beyond the end of the top shell.
  • the top frame 12 comprises a decorative cover for razor attachment mechanism 17, 17A which is affixed to the end of bottom shell 16; cap 18 is optionally placed on the top frame.
  • Attachment means are provided on the top and bottom shells to allow the two shells to be tightly and permanently attached to each other.
  • snaps 19 protrude from the top shell and fit into grooves 20 in the bottom shell.
  • the integral weight member 10 contains snap feature 14 which allows the integral weight member to be directly affixed to either or both of the top and bottom shells.
  • the integral weight member 10 also acts as a stiffener in order provide strength to and stiffen the handle so that the handle will not break or overtly bend in response to forces encountered during shaving.
  • the integral weight member 10 may be formed from any suitable material, preferably the integral weight member is formed from a die cast material.
  • Preferable materials for the weight member include high density plastics with a specific gravity greater than 2, zinc diecast, aluminum diecast, magnesium diecast, stainless steels, copper alloys and powdered metals.
  • the weight of the weight member may vary as desired in order to provide the proper balance and "feel" to the razor handle so that the razor provides a comfortable shave.
  • the weight of the weight is in the range of about seven grams to about sixty grams, with a preferred weight of about thirty-five grams.
  • the integral weight member is preferably manufactured via a die casting process.
  • the integral weight member is inserted into the razor handle, either between the two shells or within the hollow one-piece handle.
  • the shells are permanently snapped together following the insertion of the integral weight member.
  • the integral weight member is also snapped to the either or both of the top and bottom shells.
  • the top frame portion is placed over and affixed to the razor attachment mechanism.
