Abstract

Official abstract text for this publication.

A panel including a substrate and a top layer. The top layer has a decor layer and a wear layer. The panel is provided with a first pair of opposite edges; and optionally with a second pair of opposite edges. At least one edge of the first pair of opposite edges is provided with a grout imitation.

First claim

Opening claim text (preview).

The invention claimed is: 1. A panel, comprising a substrate and a top layer, wherein the top layer comprises a decor layer and a wear layer, wherein the panel is provided at a first pair of opposite edges with coupling parts, arranged for cooperating with each other, as male coupling parts and female coupling parts, for coupling two such panels at the first pair of opposite edges to each other in a floor, wall or ceiling covering; wherein the male coupling part is provided at a male edge of the first pair of opposite edges; wherein the female coupling part is provided at a female edge of the first pair of opposite edges; wherein the coupling parts are provided with mechanical locking means arranged to prevent a drifting apart of two coupled panels into a direction perpendicular to a surface of the coupled panels as and into a direction perpendicular to respective coupled edges of the two coupled panels in a plane parallel to the coupled panels; wherein the male coupling part, comprises a section of an upper surface provided below the surface of the panel and below a location of the decor layer, wherein said upper surface of said section is provided with a substantially uniform color; wherein a visual appearance of said upper surface of said section differs over a full surface thereof from the visual appearance of a decor layer, wherein in a coupled condition of a first such panel coupled at the male edge thereof onto the female edge of a second such panel, the female edge overlaps part of the upper surface of said section of the male edge of the first such panel such that part of the upper surface of said section of the male edge of the first such panel is hidden from view whereas part of the upper surface of said section is visible in the view perpendicular to the surface of the coupled panels, wherein the part of the upper surface of said section that is visible in the view perpendicular to the surface of the coupled panels is at least 1.5 mm wide. 2. The panel as in claim 1 , wherein at least part of the or an entirety of the upper surface of said section is visible in the view perpendicular to a surface of the coupled panels parallel with a surface of the panel. 3. The panel as in claim 1 , wherein the female edge of the second such panel contacts the upper surface of said section of the male edge of the first such panel provided below the surface of the panel and below the location of the decor layer in a first zone of the upper surface of the male coupling part; and wherein the upper surface of the male edge, of the male coupling part, comprises a second zone less distal than the first zone, wherein the female edge of the second such panel overlaps the second zone without contacting it but such that the second zone is hidden from view. 4. The panel as in claim 3 , wherein the panel comprises a second pair of opposite edges; wherein the panel is provided at the second pair of opposite edges with second coupling parts, arranged for cooperating with each other, substantially as second male coupling parts and second female coupling parts, for coupling two such panels at the second pair of opposite edges to each other in a floor, wall or ceiling covering; wherein the second male coupling part is provided at a second male edge of second pair of opposite edges; wherein the second female coupling part is provided at the second female edge of the panels; wherein the second coupling parts are provided with second mechanical locking means arranged to prevent the drifting apart of two such panels coupled at the second pair of opposite edges into the direction perpendicular to the surface of the coupled panels and into the direction perpendicular to the respective coupled edges in the plane parallel to the coupled panels; wherein the second male edge, the second male coupling part, comprises a section the upper surface provided below the surface of the panel and below the location of the decor layer, wherein said upper surface of said section of said second male edge is provided with a substantially uniform color; wherein the visual appearance of said upper surface of said section of said second male edge differs over a full surface thereof from the visual appearance of the decor layer, wherein in coupled condition of the first such panel coupled at the second male edge onto the second female edge of a third such panel, the second female edge of the third such panel overlaps part of the upper surface of said section of the second male edge of the first such panel, such that part of the upper surface of said section of the second male edge of the first such panel is hidden from view whereas part of the upper surface of said section of the second male edge of the first such panel is visible in the view perpendicular to the surface of the coupled panels, wherein the part of the upper surface of said section of the second male edge that is visible in the view perpendicular to the surface of the coupled panels is at least 1.5 mm wide. 5. The panel as in claim 4 , wherein the coupling parts at the second pair of opposite edges are configured such that in coupled condition of the panel with another such panel at the respective edges of the second pair of opposite edges, said mechanical locking means arranged to prevent the drifting apart of the locked panels in the direction perpendicular to the second pair of opposite edges and parallel with the surface of the coupled panels prevent said drifting apart while allowing a play in the direction perpendicular to the second pair of opposite edges of at least 0.2 mm. 6. The panel as in claim 5 , wherein said allowing said play in the direction perpendicular to the second pair of opposite edges and parallel with the surface of the coupled panels is at least in part made possible by an elastic deformation of at least one of the second female coupling part; or wherein said play does not require an elastic deformation of at least one of the coupling parts; and/or wherein said allowing said play in the direction perpendicular to the second pair of opposite edges and parallel with the surface of the coupled panels is at least in part made possible by the relative position in the direction perpendicular to the first pair of opposite edges parallel with the surface of the panels coupled at the second pair of opposite edges of the overlap of the second female edge of the upper surface of said section of the second male edge. 7. The panel as in claim 1 , wherein at least one recess is provided on the surface of the panel parallel with the first pair of opposite edges, wherein the at least one recess is bordered at both sides parallel with the first pair of opposite edges by a surface of the panel, wherein a bottom of the at least one recess has substantially a same color as the part of the upper surface of said section of the male edge visible in the view perpendicular to the surface of the coupled panels. 8. The panel as in claim 7 , wherein at least part of the section of the male edge the upper surface provided below the surface of the panel and below the location of the decor layer, is provided with a lacquer layer; and wherein the male edge and the female edge are provided with bevels wherein the bevels are at least partly provided with a same lacquer layer, wherein said lacquer layer on the bevels extends from below the decor layer to a position above the decor layer. 9. The panel as in claim 8 , wherein the lacquer layer comprises sand and/or particles having a particle size larger than 20 μm and wherein at least part of said sand and/or of said particles are present at a surface of the lacquer layer; creating a rough surface of the recess; and/or wherein the lacquer is an acryla
