Adhesiveless decorative floor tile

[0011]In one preferred embodiment of the invention, a decorative floor tile includes at least one decorative layer and a backing layer comprising an array of resilient annular projections, wherein each annular projection comprises a concave exposed top surface, an outside wall surface and an inside wall surface. The inside wall surface defines a blind passageway within the projection. When the decorative floor tile is installed over an underlying surface, and pressure is applied to the decorative floor tile, a vacuum is created within the blind passageway of the projections which adheres the floor tile to the underlying surface. The vacuum increases the amount of frictional drag between the tile and the underlying surface, and thus allows the tile to remain in place without the need for an adhesive.

[0012]Referring to FIGS. 1 and 2, a decorative floor tile 1 formed in accordance with one embodiment of the invention includes a decorative layer 2, e.g., a 15.3 cm×91.5 cm, Luxury Vinyl Til
