Replaceable shaving assemblies are disclosed that include a razor cartridge comprising: an elongated housing defining a central open area, and, adjacent each short edge of the housing, a clip-receiving aperture and a clip-receiving channel; a plurality of blades disposed within the open area of the housing, and a pair of clips, each clip having a first leg and a second leg, the first leg extending through the clip-receiving aperture and being bent against a lower surface of the housing, and the second leg being wrapped around the housing and seated in the clip-receiving channel. Shaving systems including such shaving assemblies are also disclosed, as are methods of using such shaving systems and methods of manufacturing these cartridges.
1. A razor cartridge comprising:
an elongated housing defining a central open area, and, adjacent each short edge of the housing, a clip-receiving aperture and a clip-receiving channel;
a plurality of blades disposed within the open area of the housing; and
a pair of clips, each clip having a first leg and a second leg, the first leg extending through a corresponding clip-receiving aperture and being bent against a lower surface of the housing, and the second leg wrapped around a corresponding channel support member of the housing and seated in a corresponding clip-receiving channel,
wherein the channel support member is shaped to define an opening at the lower surface of the housing,
wherein at least the opening is covered by a portion of the second leg to define at least an elongated empty space within the opening which extends along a height of the channel support member,
wherein a profile of the channel support member is formed in a closed-end recess and the opening corresponds to an open side of the closed-end recess, and
wherein the channel support member comprises a first surface and a second surface angled with respect to the first surface at the clip receiving channel, wherein the second surface is adjacent to a corner of the channel support member such that the second leg is bent around the first surface, the second surface, and the corner in a double-bend configuration.
2. The razor cartridge of claim 1 , wherein each clip-receiving channel is recessed at least 0.05 mm from an adjacent non-recessed surface of the housing.
3. The razor cartridge of claim 1 , wherein the plurality of blades are supported by positioning elements arranged adjacent each short edge of the housing and configured to secure positioning of the blades.
4. The razor cartridge of claim 3 , wherein the plurality of blades are further supported by additional positioning elements extending upwardly in the open area.
5. The razor cartridge of claim 3 , wherein at least some of the positioning elements are disposed between the clip-receiving aperture and the clip receiving channel adjacent each short edge of the housing.
6. The razor cartridge of claim 1 , wherein each clip-receiving channel has an upper radiused surface.
7. The razor cartridge of claim 1 , wherein the open area extends between the clip-receiving aperture and the clip-receiving channel adjacent each short edge of the housing.
