Abstract

In a razor cartridge, a platform portion has a first cartridge section that includes at least one first pair of razor blades position therein. Each of the first pair or razor blades has an at least partially exposed cutting edge. A second cartridge section is also provided and is coupled to the platform portion. The second cartridge section includes at least one pair of second razor blades positioned therein, each of the second pair of razor blades also has an at least partially exposed cutting edge. The razor cartridge can be mounted either temporarily or permanently to a handle and the cutting edges of each of the first and second pair of razor blades face one another so that during a shaving operation, the razor cartridge can cut hair when drawn over a user's skin in either of two generally opposite directions.

Dependent claims

A razor cartridge comprising:

a platform portion having a first cartridge section including at least one first pair of razor blades positioned therein, each of said first pair of razor blades having an at least partially exposed cutting edge, and a second cartridge section coupled to said platform portion, said second cartridge section including at least one second pair of razor blades positioned therein, each of said second pair of razor blades having an at least partially exposed cutting edge, said first cartridge section including a first housing coupled to said platform portion, said first pair of razor blades being positioned in said first housing, and said second cartridge section including a second housing coupled to said platform portion, said second pair of razor blades being positioned in said second housing;
mounting means for rotatably coupling said platform portion to a handle;
wherein
said platform portion defines first and second limiting surfaces positioned on an underside thereof adjacent to a first end of said platform portion, and third and fourth limiting surfaces positioned on said underside of said platform portion adjacent to a second opposing end of said platform portion, said limiting surfaces being configured relative to one another to establish a range of rotational movement of said razor cartridge relative to a handle when said razor cartridge is rotatably mounted thereon;
and wherein
said cutting edges of said first pair of razor blades are positioned opposite and facing toward said cutting edges of said second pair of razor blades so that during a shaving operation, the razor cartridge can cut hair when drawn over a user's skin in either of two generally opposite directions.
