Abstract
A shaving razor cartridge with a housing molded from a first polymeric material and having a top surface and an opposing bottom surface. The housing has a wall partially defining an opening extending from the top surface to the bottom surface. The wall has a pair of arms each with a distal end extending toward each other defining a gap. A guard is toward a front of the housing. A cap is toward a rear of the housing. At least one blade is mounted between the guard and the cap. A bridge interconnects the distal ends. The bridge is molded from a second polymeric material that is different than the first polymeric material.

A shaving razor cartridge comprising:
- a housing molded from a first polymeric material and having a top surface and an opposing bottom surface, the housing having a wall partially defining an opening extending from the top surface to the bottom surface, the wall having a pair of arms each having a distal end that extending toward each other defining a gap;
- a guard toward a front of the housing;
- a cap toward a rear of the housing;
- at least one blade mounted between the guard and the cap;
- and
- a bridge interconnecting the distal ends, wherein the bridge is molded from a second polymeric material that is different than the first polymeric material, wherein a secant modulus calculated at 1% engineering strain of the first polymeric material is more than 10% different than a secant modulus calculated at 1% engineering strain of the second polymeric material.
A method of manufacturing a shaving razor cartridge comprising:
- molding a housing having a wall partially defining an opening that extends from a top surface to a bottom surface of the housing;
- molding a bridge comprising a polymeric material that is different than a polymeric material that comprises the housing to enclose the opening, wherein said molding of the bridge comprises molding a skin contacting surface over the top surface of the housing.
