Device Having Dual Renewable Blades For Treating a Target Surface and Replaceable Cartridge Therefor
First Claim
1. A device for applying a liquid to a target surface to and treating said liquid while on said target surface, said device being movable along said target surface when held by a user and comprising:
- a housing for holding a prewetted substrate suitable for applying a liquid to a target surface and for holding a sheet, said sheet to be applied to the target surface trailing the prewetted substrate when said device is moved along the target surface by a user;
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 from a proximal end juxtaposed with said housing to a distal end suitable for pressing the sheet against the target surface, said sheet pressure applying member having an opposed first side and second side 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 from a proximal end juxtaposed with a housing towards a distal end suitable for pressing the prewetted substrate against the target surface, said prewetted substrate pressure applying member having an opposed first side and second side intermediate and connecting said proximal end and said distal end;
a sheet advance mechanism for longitudinally advancing the sheet, when said sheet is loaded into said housing, said sheet being longitudinally advanced across the distal end of said sheet pressure applying member;
a prewetted substrate advance mechanism for longitudinally advancing the prewetted substrate, when loaded into said housing, across the distal end of said prewetted substrate pressure applying member; and
a manually activatable mechanism for causing longitudinal advance of a sheet and of a prewetted substrate when the sheet and the prewetted substrate are loaded into said device.

Abstract
A device for treating a target surface, such as occurs when cleaning a window. The device has a squeegee blade or other member to apply pressure to the target surface. A sheet movably covers the blade, to present a fresh covering to the target surface with each use. The fresh surface provides for improved removal of the liquid from, or improved treatment of the liquid on, the target surface. Additionally a sheet may comprise a prewetted substrate to apply the liquid to the target surface. One or both of the sheets may be disposed in a cartridge insertable to and removable from the device.

8. 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. - View Dependent Claims (9, 10, 11, 12)

13. 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. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
