RAZOR CARTRIDGE
A razor cartridge comprising a core including a blade mounting portion configured to receive one or more blades and at least one of a portion of a frame, a guard and a cap, said razor cartridge comprising one or more skin contacting portions associated with one or more portions of the core, wherein one or more of the skin contacting portions comprise a lubricious layer formed of a lubricious layer composition including a matrix component and a lubricious component.
1 . A razor cartridge comprising a core including a blade mounting portion configured to receive one or more blades and at least one of a portion of a frame, a guard and a cap, said razor cartridge comprising one or more skin contacting portions associated with one or more portions of the core, wherein one or more of the skin contacting portions comprise a lubricious layer formed of a lubricious layer composition including a matrix component and a lubricious component.
2 . The razor cartridge of claim 1 wherein the lubricious layer is formed directly onto at least a portion of the core by injection molding the lubricious layer composition onto the core.
3 . The razor cartridge of claim 1 wherein the lubricious layer is formed independently from the core and then subsequently attached to the core.
4 . The razor cartridge of claim 1 wherein at least a portion of the core has a concave rear surface.
5 . The razor cartridge of claim 4 wherein the concave rear surface comprises one or more supports.
6 . The razor cartridge of claim 1 wherein the core comprises one or more cut-away areas in which the lubricious layer is fashioned.
7 . The razor cartridge of claim 6 wherein at least a portion of the cut-away areas terminate in a collar extending around at least a portion of a bottom edge of the core.
8 . The razor cartridge of claim 1 wherein the matrix component of the lubricious layer composition comprises a PBAT.
9 . The razor cartridge of claim 1 wherein PBAT comprises from about 2 to about 20 weight percent of the lubricious layer composition.
10 . The razor cartridge of claim 1 wherein PBAT comprises from about 5 to about 15 weight percent of the lubricious layer composition.
11 . The razor cartridge of claim 1 wherein the blade mounting portion and at least a portion of the frame of the core on which a lubricious layer is formed are integrally formed.
12 . The razor cartridge of claim 1 comprising more than one lubricious layer, including a first lubricious layer that is overmolded onto the core and a second lubricious layer that is formed independently from the core and attached to the core.
13 . The razor cartridge of claim 12 wherein the first lubricious layer is molded directly onto at least a portion of the core.
14 . The razor cartridge of claim 12 wherein the first lubricious layer and the second lubricious layer have different lubrication characteristics.
15 . The razor cartridge of claim 12 wherein the first lubricious layer and the second lubricious layer are formed of different compositions.
16 . The razor cartridge of claim 12 wherein the first lubricious layer and the second lubricious layer are located independent of one another, on different parts of the core.
17 . A method of manufacturing a razor cartridge comprising:
a. integrally forming a core comprising a blade mounting portion configured to receive one or more blades and at least a portion of a frame;
b. molding a lubricious layer formed of a lubricious layer composition including a matrix component and a lubricious component onto at least a portion of the frame; and
c. attaching a lube strip to the core.
18 . The method of claim 17 wherein the distance between one of the one or more blades and the lubricious layer is minimized.
19 . The method of claim 17 wherein the step of molding the lubricious layer onto at least a portion of the frame is an initial processing of the lubricious layer composition.
20 . The method of claim 17 wherein the lubricious layer and the lube strip have different physical characteristics.
