The invention provides a new floor covering panel and floor covering system in which the floor covering panels include first and second generally planar surfaces, first and second side edges containing first and second complementary coupling members, respectively, and an adhesive composition selectively applied to at least a portion of at least one of the first and second coupling members. The adhesive composition providing the adhesive bond may be applied to at least one of the first or second coupling members during the floor covering manufacturing process. After a floor covering system is assembled, the adhesive composition provides a substantially non-refastenable bond between mated floor covering panels.

What is claimed is: 1. A laminate floor covering panel, comprising: a. a laminate floor panel comprising a plurality of layers and having a first generally planar surface, a second generally planar surface opposed to said first surface, a first side edge and an opposed second side edge, each respective side edge extending between said first and second surfaces, respectively, a first coupling member defined within the first edge of the panel and comprising a protrusion extending therefrom, a complementary second coupling member defined within the second edge of the panel and comprising a recess sized and shaped to receive said protrusion therein; and b. a self activating adhesive composition having an open time of at least about one month selectively applied to at least a portion of at least one of the first and second coupling members. 2. The laminate floor covering panel of claim 1, further comprising a first and a second one of said floor covering panels, respectively, the first coupling member of the first panel being received within the second coupling member of the second panel, and wherein the adhesive composition is positioned between the respective first and second coupling members of the two panels and forms an adhesive bond there between. 3. The laminate floor covering material of claim 2, wherein the adhesive composition forms a substantially non-refastenable bond after about 48 hours of connective attachment. 4. The laminate floor covering material of claim 2, wherein the adhesive bond is substantially separable prior to about 48 hours of connective attachment. 5. The laminate floor covering panel of claim 2, wherein the first coupling member of the first panel engages the second coupling member of the second panel along a plurality of contact zones defined between the respective coupling members. 6. The laminate floor covering panel of claim 2, wherein the first coupling member of the first panel engages the second coupling member of the second panel along at least one contact zone defined between the respective coupling members. 7. The laminate floor covering panel of claim 6, wherein the adhesive composition is applied to a selected contact zone and does not otherwise extend to any portions of the respective coupling members outside of the selected contact zone. 8. The laminate floor covering panel of claim 7, wherein the selected contact zone comprises a locking structure for preventing substantial separation of the first panel from the second panel in a direction perpendicular to the respective side edges of the panels and parallel to the respective surfaces thereof. 9. The laminate floor covering panel of claim 8, the second coupling member further comprising an upper lip defined within the second side edge between the recess of the second coupling member and the first surface of the panel, and a lower lip defined within the second side edge between said recess and the second surface of the panel, and a detent defined within said lower lip. 10. The laminate floor covering panel of claim 9, wherein said locking structure further comprises a rib extending from the protrusion of the first coupling member and the detent defined within the lower lip of the second coupling member, the rib being received within the detent and contacting the detent along the selected contact zone. 11. The laminate floor covering panel of claim 10, wherein the selected contact zone is substantially planar. 12. The laminate floor covering panel of claim 11, wherein the selected contact zone forms an acute angle with respect to the second surface of the respective panels, said acute angle being measured from the second surface to the contact zone in a counter-clockwise direction. 13. The laminate floor covering panel of claim 1, wherein the adhesive composition comprises a contact adhesive. 14. The laminate floor covering panel of claim 1, wherein the adhesive composition comprises an adhesive polymer comprising one or more of: polychloroprene, polyurethane, styrene-isoprene copolymer, styrene-butadiene copolymer, a polyimide, polyvinyl chloride, nitrocellulose, polyisoprene, acrylonitrile-butadiene-isoprene terpolymer, butadiene-methacrylonitrile copolymer, polyethylene-vinyl acetate copolymer, or an acrylic polymer. 15. The laminate floor covering panel of claim 1, wherein the at least one adhesive composition comprises an aqueous dispersion of an acrylic polymer. 16. The laminate floor covering panel of claim 15, wherein the acrylic polymer is derived from one or more monomers comprising: methyl acrylate, ethyl acrylate, butyl acrylate, cyclohexyl acrylate, 2-ethylhexyl acrylate, t-octyl acrylate, dodecyl acrylate, and octadecyl acrylate. 17. The laminate floor covering panel of claim 15, wherein the acrylic polymer is derived from one or more monomers comprising: methyl, acrylate, ethyl acrylate, butyl acrylate, or 2-ethyihexyl acrylate. 18. The laminate floor covering panel of claim 1, wherein the adhesive composition has an open time of at least about six months.
