Abstract

The floor plank is a laminate of two layers of flexible plastic sheet material laminated together in offset relationship to define an offset marginal portion for each of the layers. Each of the offset marginal portions have oppositely facing adhesive coated surfaces. A foam layer and/or a fiberglass sheet can also be included in the laminate structure of the floor plank. The floor plank can conform to surface contours of a floor base. The bottom layer of the floor plank, whether it is plastic sheet or foam, is conformable to surface irregularities of the floor base. A one piece releasable packaging device covers the oppositely facing adhesive coated surfaces of the offset marginal portions.

Claims (6)

1. A method of covering exposed adhesive portions of a floor plank having two layers of plastic sheet material laminated together in offset relationship such that a first layer has a first marginal portion that is offset from the second layer, and the second layer has a second marginal portion that is offset from the first layer, comprising,

covering a first exposed adhesive coated marginal surface of a floor plank that faces a first direction and is at a first perimeter portion of the floor plank, with one continuous strip of flexible releasable material, and covering a second exposed adhesive coated marginal surface of the floor plank that faces a second direction opposite the first direction and is at a second perimeter portion of the floor plank that does not overlap the first perimeter portion of the floor plank, with the one continuous strip of flexible releasable material, whereby both of the oppositely facing first and second adhesive coated marginal surfaces at the first and second non-overlapping perimeter portions of the floor plank are covered with the one continuous strip of flexible releasable material.

2. The method of claim 1 including forming the releasable material with a closed polygonal periphery.

3. The method of claim 1 including forming the releasable material with a rectangular outer periphery and a rectangular inner periphery, and an open inner rectangular space surrounded by the releasable material.

4. The method of claim 1 wherein the releasable material is a silicone coated paper.
