Abstract:
1. An embossed sheet, comprising: at least a first and a second ply of creped tissue having a basis weight between 12 and 30 g/m wherein the first ply has a first embossed pattern comprising a series of first aligned protrusions of frustoconical overall shape, the tops of which are oriented towards an inside of the sheet; wherein the second ply comprises a first and a second series of protrusions, the tops of which are oriented towards the inside of the sheet, the second series of protrusions having a height greater than that of the first series of protrusions; wherein the first aligned protrusions of the first ply form series of circles that are concentric in a set of at least 3, circles; wherein highest protrusions of the second ply form series of concentric circles in a set of at least 3, disposed complementary and concentric with respective circles of the series of circles of the first ply; wherein the first aligned protrusions of the first ply and the highest protrusions of the second ply are nested with respect to one another, in that lowest protrusions of the second ply are arranged between the first aligned protrusions of the first ply in spaces between the complementary series of circles; wherein a subset of the first aligned protrusions of the first ply are arranged in the spaces between the complementary series of circles, in that some of the highest protrusions of the second ply are arranged among the lowest protrusions of the second ply, nested with respect to the subset of the first aligned protrusions of the first ply arranged in the spaces between the complementary series of circles, so as to create empty spaces between the two plies and promote a rapid absorption of liquid.
