Abstract

A dispenser and method for dispensing cleaning materials which includes a roll of web material, a drive unit for automatically paying a predetermined amount of such material from the dispenser, such dispenser including a liquid applicator operative to apply a predetermined amount of liquid evenly distributed to the web paying from the dispenser.

Claims

1. A cleaning material web dispensing unit comprising a supply of cleaning material web, drive means including a pair of powered drive rollers through which such web passes operative to dispense such web from such unit in a predetermined direction, liquid applicator means located adjacent said web and spaced in said predetermined direction from said drive rollers and including a plurality of transversely spaced dispensing apertures operative to apply a measured amount of liquid to such web in a uniform predetermined pattern of droplets as it is dispensed, and liquid supply means for supplying liquid to said applicator means and including a pump which is driven by said drive means in successive discharge and intake strokes as said web is dispensed from said unit and moves past said applicator means;

whereby liquid is intermittently supplied to said applicator means by said pump and liquid is intermittently applied to said web by said applicator means after said web passes through said drive rollers and said liquid is applied to said web in a substantially uniformly distributed predetermined pattern at transversely and longitudinally spaced locations.

2. A unit as set forth in claim 1 wherein said liquid supply means includes a liquid reservoir and said pump has a cylinder, piston, and check valves, said check valves being operative to obtain unidirectional flow through said pump from said reservoir to said applicator means.

3. A unit as set forth in claim 1 wherein said pump includes a reciprocating piston driven by cam means operatively associated with said drive means, said piston being spring biased against said cam means to maintain operative contact between the same.

4. A unit as set forth in claim 1 including timer means operative to control the duration of energization of said drive means thus to dispense a measured amount of such material web from said unit when said drive means is energized through said timer means.

5. A unit as set forth in claim 1 including means operative to heat such liquid.

6. A unit as set forth in claim 1 wherein such material web includes an impregnated agent adapted to react with such liquid to obtain a cleansing action.
