Device Having Dual Renewable Blades For Treating a Target Surface and Replaceable Cartridge Therefor

A device for applying a liquid to a target surface to and treating said liquid while on said target surface, said device comprising:

• a housing holding a prewetted substrate suitable for applying a liquid to a target surface and holding a sheet, said sheet to be applied to the target surface trailing the prewetted substrate;
• a handle pivotably connected to said housing in floating relationship therewith;
• a sheet pressure applying member, said sheet pressure applying member having a primary orientation extending in a widthwise direction, said sheet pressure applying member projecting in a longitudinal direction from a proximal end juxtaposed with a housing towards a distal end suitable for pressing said sheet against the target surface, said sheet pressure applying member having opposed first and second sides intermediate and connecting said proximal end and said distal end;
• a prewetted substrate pressure applying member, said prewetted substrate pressure applying member having a primary orientation extending in a widthwise direction, said prewetted substrate pressure applying member projecting in a longitudinal direction from a proximal end juxtaposed with a housing towards a distal end suitable for contacting a film against the target surface, said prewetted substrate pressure applying member having opposed first and second sides intermediate and connecting said proximal end and said distal end;
• and
• an advance mechanism for longitudinally advancing said sheet across the distal end of said sheet pressure applying member and for concurrently longitudinally advancing said prewetted substrate across the distal end of said prewetted substrate pressure applying member in response to a single activation of said advance mechanism by a user.

A cartridge insertable into and removable from a device for treating a liquid on a target surface, said cartridge comprising:

• an axially rotatable supply roll;
• an axially rotatable take-up roll, said take-up roll being operably connectable to a sheet advance mechanism disposed in said device, whereby actuation of said sheet advance mechanism causes rotation of said take-up roll;
• and
• a sheet material wound on said supply roll and joined in a longitudinal path to said take-up roll whereby said sheet material can travel from said supply roll to said take-up roll.
