Abstract

An improved tacky floor mat for removing loose particles of dirt, dust and the like coming in contact therewith from shoes, wheels, etc. The floor mat includes a stack of adhered, peelable sheets with a layer of adhesive on the upper surface of each sheet. As the adhesive ability of each sheet is diminished it is peeled from the stack to expose the next fresh sheet. To improve the peeling of the sheet a thin coating of non-adhesive material is print deposited on the adhesive layer in a corner of the upper surface of each sheet. To inform the user which corner has been treated the thin coating is generally a different color than the sheets.

Claims

1. In a tacky floor mat for removing loose particles of dirt, dust and the like coming in pressure contact therewith of the type having a stack containing a plurality of superimposed adjacently adhered sheets, each sheet being substantially identical in size and having a pressure-sensitive adhesive layer on substantially the entire upper surface thereof, with the lower surface of each sheet being less adhesively treated than said upper surface of each sheet so that said adjacently adhered sheets are peelable from each other in descending order, wherein the improvement to initiate the peeling of each sheet comprises:

a thin coating of non-adhesive material being print deposited on top of said adhesive layer in at least one corner of said upper surface of each sheet to render said upper corner non-adhesive to facilitate peeling of said sheet, said non-adhesive coating being a different color than the color of each of said sheets to readily indicate the section whereupon said peeling is to originate, said coating comprising an ink for color, an adhesive coating ingredient and silicone for adhesive release properties.

2. An improved tacky floor mat as defined in claim 1 wherein said lower surface of each sheet is substantially non-adhesively treated.

3. An improved tacky floor mat as defined in claim 1 wherein said coating has a thickness range greater than zero and less than or equal to 0.003 inches.
