UNITARY CARTRIDGE

WIPO Patent Application WO/2010/093134

A2

The present invention relates to a shaving razor cartridge, comprising: an upper housing having one or more curved razor blades, an exposing portion for exposing the edges of the razor blades to the outside, and a guard; and a lower housing coupled to the upper housing, having a blade mounting portion for supporting the razor blades, wherein the bottoms of said one or more razor blades are supported at both ends and the center of the blade mounting portion, and both ends of said razor blades have notches such that the tops of the razor blades are supported and vertically connected to both ends of the upper housing. As the notches are formed at both ends of the razor blades to enable the razor blades to be accommodated in the space between the blade mounting portion and the upper housing, the necessity of a clip for fixing razor blades is eliminated, and the deformation of the razor blades can be prevented, thus making products slim and small-sized, and enabling the automatic assembly of cartridges of a variety of shapes and reducing production costs.
