Abstract

In the field of decorative floor coverings, decorative panels are known having a MDF (Medium Density Board) or HDF (High Density Board) based core layer on top of which a decorative substrate is attached to provide the panels a desired appearance. The invention relates to a panel, in particular a decorative panel, a floor panel, a ceiling panel or a wall panel. The invention also relates to a floor covering consisting of a plurality of mutually coupled panels.

First claim

1 - 67 . (canceled)

68 . A decorative panel, in particular a floor panel, ceiling panel or wall panel, comprising:
a core provided with an upper side and a lower side, a decorative top structure 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,
wherein at least one antimicrobial substance is applied as a coating on at least a part of the first coupling profile and/or at least a part of the second coupling profile.

69 . The panel according to claim 68 , wherein the first coupling profile and the second coupling profile make integral part of the core.

70 . The panel according to claim 68 , wherein the at least one antimicrobial substance is dispersed within the core and/or the top structure.

71 . The panel according to claim 68 , wherein at least one antimicrobial substance is applied as a coating on the core and/or the top structure.

72 . The panel according to claim 68 , wherein at least one antimicrobial substance is applied as a coating on a surface of the first coupling profile being configured to face the second coupling profile of an adjacent panel, in coupled condition.

73 . The panel according to claim 68 , wherein at least one antimicrobial substance is applied as a coating on a surface of the second coupling profile being configured to face the first coupling profile of an adjacent panel, in coupled condition.

74 . The panel according to claim 68 , wherein at least one antimicrobial substance is a zinc complex, preferably zinc pyrithione.

75 . The panel according to claim 68 , wherein at least one antimicrobial substance is N-butyl-1,2-benzisothiazolin-3-one (BBIT).

76 . The panel according to claim 68 , wherein the panel, in particular said core and/or said top structure and/or the first coupling profile and/or the second coupling profile is provided with a mixture of different antimicrobial substances, which mixture preferably comprises a zinc complex, preferably zinc pyrithione, and N-butyl-1,2-benzisothiazolin-3-one (BBIT).

77 . The panel according to claim 68 , wherein the core comprises at least one polymer.

78 . The panel according to claim 68 , wherein the core comprises at least one plasticizer.

79 . The panel according to claim 68 , wherein the antimicrobial substance is at least one antimicrobial substance chosen from the group consisting of:
1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole (Propiconazole); (benzothiazol-2-ylthio)methyl thiocyanate (TCMTB); 1-(4-chlorophenyl)-4,4-dimethyl-3-(1,2,4-triazol-1-ylmethyl)pentan-3-ol (Tebuconazole); 1-[[2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole (Propiconazole); 2-butyl-benzo[d]isothiazol-3-one (BBIT); 2-octyl-2H-isothiazol-3-one (OIT); 2-thiazol-4-yl-1H-benzoimidazole (Thiabendazole); 3-iodo-2-propynylbutylcarbamate (IPBC); 4,5-Dichloro-2-octylisothiazol-3(2H)-one (DCOIT)); 10,10-oxybisphenoxarsine (OBPA); Carbendazim; Chlorocresol; Fludioxonil; N-(trichloromethylthio)phthalimide (Folpet); p-[(diiodomethyl)sulphonyl]toluene; Pyrithione zinc (Zinc pyrithione (Zpt)); Terbutryn; and Thiram.

80 . The panel according to claim 68 , wherein the core and/or the backing layer comprises at least one filler chosen from the group consisting of: a mineral, preferably calcium carbonate; a pigment, a modifier, fibers.

81 . The panel according to claim 68 , wherein at least one polymer of the core is foamed.

82 . The panel according to claim 68 , wherein the panel comprises a plurality of reinforcement layers, wherein, preferably, at least one first reinforcement layer is located in a top portion of the core, and wherein at least one second reinforcement layer is located in a bottom portion of the core.

83 . The panel according to claim 68 , wherein at least one reinforcement layer extends in only one coupling profile of the first and second coupling profile.

84 . The panel according to claim 68 , wherein the first coupling profile comprises:
an upward tongue, at least one upward flank lying at a distance from the upward tongue, an upward groove formed in between the upward tongue and the upward flank wherein the upward groove is adapted to receive at least a part of a downward tongue of a second coupling profile of an adjacent panel, and at least one first locking element, preferably provided at a distant side of the upward tongue facing away from the upward flank,
and wherein the second coupling profile comprises:
a first downward tongue, at least one first downward flank lying at a distance from the downward tongue, a first downward groove formed in between the downward tongue and the downward flank, wherein the downward groove is adapted to receive at least a part of an upward tongue of a first coupling profile of an adjacent panel, and at least one second locking element adapted for co-action with a first locking element of an adjacent panel, said second locking element preferably being provided at the downward flank.

85 . The panel according to claim 68 , wherein the panel comprises at least one third coupling profile and at least one fourth coupling profile located respectively at a third panel edge and a fourth panel edge, wherein the third coupling profile comprises:
a sideward tongue extending in a direction substantially parallel to the upper side of the core, at least one second downward flank lying at a distance from the sideward tongue, and a second downward groove formed between the sideward tongue and the second downward flank,
wherein the fourth coupling profile comprises:
a third groove configured for accommodating at least a part of the sideward tongue of the third coupling profile of an adjacent panel, said third groove being defined by an upper lip and a lower lip, wherein said lower lip is provided with an upward locking element,
wherein the third coupling profile and the fourth coupling profile are configured such that two of such panels can be coupled to each other by means of a turning movement, wherein, in coupled condition: at least a part of the sideward tongue of a first panel is inserted into the third groove of an adjacent, second panel, and wherein at least a part of the upward locking element of said second panel is inserted into the second downward groove of said first panel.

86 . The panel according to claim 68 , wherein the core comprises magnesium oxide, magnesium hydroxide, and/or magnesium based cement.

87 . A decorative covering, in particular a decorative floor covering, decorative ceiling covering, or decorative wall covering, comprising a plurality of mutually coupled decorative panels according to claim 68 .
