Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 59 words
A spring clip for holding a stack of razor blade cartridges of generally oblong shape comprising a U-shaped member of elastic sheet metal having a main rear wall and top and bottom projecting legs, each of said legs being bifurcated to provide leaf fingers laterally spaced adapted to engage an adjacent cartridge with an intervening slot between the fingers.
Claim 2
Dependent Claim 59 words
A spring clip for holding a stack of razor blade cartridges of generally oblong shape comprising a U-shaped member of elastic sheet metal having a main rear wall and top and bottom projecting legs, each of said legs being bifurcated to provide leaf fingers laterally spaced adapted to engage an adjacent cartridge with an intervening slot between the fingers.
Claim 3
Dependent Claim 21 words
The spring clip claimed in claim 1 wherein each said leg includes a terminal portion connecting together said leaf fingers thereof.
Claim 4
Dependent Claim 59 words
The spring clip claimed in claim 2 wherein said wall defines an opening adjacent said top leg, said top leg terminal portion being disposed substantially parallel to said wall and including a slot adjacent the ends of said leaf fingers, said slot being registrable with said wall opening upon preselected movement of said leaf fingers of said top leg.
Claim 5
Dependent Claim 157 words
An elastic support for holding a stack of razor blade cartridges and facilitating insertion and removal of such cartridges by a razor handle key complementary therewith, comprising an upstanding wall member and first and second elastic legs projecting from respective first and second opposite ends of said wall member, said legs each having an initial portion projecting from and generally orthogonal to said wall member and a second portion bent from the ends of said initial portion toward said wall member and defining mutually spaced leaf fingers engageable with said cartridge stack, said first leg initial portion defining a slot extending throughout the entire extent thereof to enable movement of said razor handle key therethrough for said cartridge insertion, said second leg initial portion defining a slot adjacent said end thereof and extending throughout less than the extent of said second leg initial portion to enable entry of said razor handle key therein for said cartridge removal.
Claim 6
Dependent Claim 157 words
An elastic support for holding a stack of razor blade cartridges and facilitating insertion and removal of such cartridges by a razor handle key complementary therewith, comprising an upstanding wall member and first and second elastic legs projecting from respective first and second opposite ends of said wall member, said legs each having an initial portion projecting from and generally orthogonal to said wall member and a second portion bent from the ends of said initial portion toward said wall member and defining mutually spaced leaf fingers engageable with said cartridge stack, said first leg initial portion defining a slot extending throughout the entire extent thereof to enable movement of said razor handle key therethrough for said cartridge insertion, said second leg initial portion defining a slot adjacent said end thereof and extending throughout less than the extent of said second leg initial portion to enable entry of said razor handle key therein for said cartridge removal.
Claim 7
Dependent Claim 22 words
The elastic support claimed in claim 4 wherein each said leg includes a terminal portion connecting together said spaced leaf fingers thereof.
Claim 8
Dependent Claim 73 words
The elastic support claimed in claim 5 wherein said wall member defines an opening adjacent said first end thereof and wherein said terminal portion of said first leg is disposed substantially parallel to said wall and defines a slot adjacent said leaf fingers and registrable with said wall member opening upon preselected movement of said leaf fingers to enable movement of said razor handle key through said wall member and said first leg.
Claim 9
Dependent Claim 21 words
The elastic support claimed in claim 6 wherein said wall member opening and said first leg slot are of like configuration.
Claim 10
Dependent Claim 29 words
The elastic support claimed in claim 6 wherein said wall member includes upstanding spaced ribs projecting therefrom and cooperative with said first leg terminal portion for guiding movement thereof.
Claim 11
Dependent Claim 24 words
The elastic support claimed in claim 4 wherein said wall member and said legs are constituted by a single integral sheet of elastic material.
Claim 12
Dependent Claim 24 words
The elastic support claimed in claim 5 wherein said wall member and said legs are constituted by a single integral sheet of elastic material.
Claim 13
Dependent Claim 17 words
The elastic support claimed in claim 9 wherein said single integral sheet is comprised of sheet metal.
Claim 14
Dependent Claim 17 words
The elastic support claimed in claim 10 wherein said single integral sheet is comprised of sheet metal.
