Abstract
The invention relates to a decorative panel, in particular a floor panel, ceiling panel or wall panel. The invention also relates to a decorative covering, in particular a decorative floor covering, decorative ceiling covering, or decorative wall covering, including a plurality of mutually coupled decorative panels according to the invention. The invention further relates to a core for use in a panel according to the invention. The invention additionally relates to a method of producing a decorative panel, in particular a decorative panel according to the invention. The invention also relates to an extruded for use in said method according to the invention.
Claims20
A decorative panel, comprising:
- a core provided with an upper side and a lower side, wherein the core is at least partially made of at least one thermoplastic material,
- a decorative top structure, either directly or indirectly, affixed on said upper side of the core,
- a first panel edge comprising a first coupling profile, and a second panel edge comprising a second coupling profile being designed to engage interlockingly with said first coupling profile of an adjacent panel, both in horizontal direction and in vertical direction,
- a third panel edge comprising a third coupling profile, and a fourth panel edge comprising a fourth coupling profile being designed to engage interlockingly with said third coupling profile of an adjacent panel, both in horizontal direction and in vertical direction,
- wherein each panel edge defines at least one vertical plane (VP) perpendicular to a horizontal plane (HP), which horizontal plane (HP) is parallel to the core,
- wherein the core is provided with at least two vertically extending core grooves having a groove opening connected to the lower side and/or upper side of the core, wherein the entire part of the core grooves is arranged inside the vertical planes (VP) respectively defined by all panel edges, such that the core grooves do not intersect any coupling profile of the first coupling profile, the second coupling profile, the third coupling profile, and the fourth coupling profile,
- wherein each core groove is defined by at least one groove wall,
- wherein the core is an extruded core having a smooth surface finish without spines or protrusions, and
- wherein the core grooves are extruded core grooves having a smooth surface finish without spines or protrusions, and wherein (i) the lower side and/or upper side of the core and (ii) the groove walls of the core grooves have substantially the same smooth surface finish.

A core for use in a panel, wherein said core comprises:
- an upper side and a lower side, wherein the core is at least partially made of at least one thermoplastic material,
- a first core edge comprising a first coupling profile, and a second core edge comprising a second coupling profile being designed to engage interlockingly with said first coupling profile of an adjacent panel, both in horizontal direction and in vertical direction,
- a third core edge comprising a third coupling profile, and a fourth core edge comprising a fourth coupling profile being designed to engage interlockingly with said third coupling profile of an adjacent panel, both in horizontal direction and in vertical direction,
- wherein each core edge defines a vertical plane (VP) perpendicular to a horizontal plane (HP), which horizontal plane (HP) is parallel to the core,
- wherein the core is provided with at least two vertically extending core grooves having a groove opening connected to the lower side and/or upper side of the core, wherein the entire part of the core grooves is arranged inside the vertical planes (VP) respectively defined by all core edges, such the core grooves do not intersect any coupling profile of the first coupling profile, the second coupling profile, the third coupling profile, and the fourth coupling profile,
- wherein each core groove is defined by at least one groove wall,
- wherein the core is an extruded core having a smooth surface finish without spines or protrusions,
- wherein the core grooves are extruded core grooves having a smooth surface finish without spines or protrusions, and
- wherein the lower side and/or upper side of the core and the groove walls of the core grooves have substantially the same surface texture, and wherein (i) the lower side and/or upper side of the core and (ii) the groove walls of the core grooves have substantially the same smooth surface finish.
