Cleaning system
Disclosed are hand-held scrubbing devices of the type having a replaceable pad. These devices have a handle which is extruded and extremely flexible. The pads are multi-layer and may be pre-impregnated with a cleaner concentrate. A shipping/docking container for use therewith is also disclosed which has the capability of reducing its overall size once the product has reached the consumer.
1. A multi-layer surface treating pad, comprising:
an upper layer suitable to serve as one part of a hook/loop type fastener system;
an interior layer comprising a mix of pulp and synthetic material that is impregnated with a liquid surface treating formula; and
a lower layer which comprises an abrasive material;
wherein the pad is a cleaning pad and the formula comprises an acid; and
wherein when the pad is first wetted with water it can release a cleaning solution of at least 1 percent acid by weight, and when that same pad is then wetted a second time with water it can still release a cleaning solution of at least 1 percent acid by weight, and when that same pad is thereafter wetted a third time with water it can still release a cleaning solution of at least 1 percent acid by weight.
2. The pad of claim 1 , wherein the upper layer is suitable to serve as a loop part of a hook/loop type fastener system.
3. The pad of claim 1 , wherein the upper, interior and lower layers are welded together.
4. The pad of claim 3 , wherein the upper, interior and lower layers are welded together around their periphery so that the pad is thicker at its center than at its periphery.
5. The pad of claim 1 , wherein the upper, interior and lower layers are needle punched together around their periphery.
6. The pad of claim 1 , wherein the pad comprises a carrier liquid and a surfactant.
7. The cleaning pad of claim 1 , wherein the interior layer of the pad is such that prior to said impregnation the interior layer had a wicking characteristic such that when that the interior layer prior to impregnation had been positioned horizontally and 5 grams of 25° C. water was placed at a center, or within 1 centimeter of the center, of a top surface of the interior layer, that water would not reach a peripheral boundary of the interior layer prior to 1 minute after the 5 grams of water were so placed.
8. The cleaning pad of claim 1 , wherein the formula has less than 30 percent water by weight.
9. The cleaning pad of claim 1 , wherein the lower layer is configured so as to be capable of aerating the formula when the formula has been diluted with water, to thereby cause a resulting diluted formula to foam.
10. The pad of claim 1 , wherein an absorption capacity of the interior layer prior to impregnation with the formula was over 500% of its starting weight.
11. The pad of claim 1 , wherein the impregnating formula occupies less than 50 percent of an absorption capacity of the interior layer.
12. The pad of claim 1 , wherein the lower layer comprises a layer of air filter media.
13. The pad of claim 1 , wherein the upper layer comprises polyethylene film to enhance its structural integrity.
14. A multi-layer surface treating pad, comprising:
an upper layer suitable to serve as one part of a hook/loop type fastener system;
an interior layer comprising a mix of pulp and synthetic material that is impregnated with a surface treating formula; and
a lower layer which comprises an abrasive material;
wherein the pad is a cleaning pad and the formula comprises a carrier liquid and a surfactant; and
wherein the formula comprises a glycol ether and a nonionic surfactant.
15. A multi-layer surface treating pad, comprising:
an upper layer suitable to serve as one part of a hook/loop type fastener system;
an interior layer comprising a mix of pulp and synthetic material that has been impregnated with a liquid surface treating formula; and
a lower layer which comprises an abrasive material;
wherein the upper, interior and lower layers are attached together around their periphery so that the pad is thicker at its center than at its periphery;
wherein the upper layer was placed on the interior layer after impregnation of the interior layer with the liquid surface treating formula.
