Appeal 2007-2206
Application 10/181,977
example made of crêped cellulose wadding, also called tissue paper, with a
grammage of between 12 and 30 g/m2, endowed with protuberances which
are obtained by embossing” (Specification 1). Embossing the paper is
desirable because it “gives fullness to the sheet and it leads to improved
liquid absorption, touch and softness” (id.).
The Specification discloses “an improved design of an embossed
sheet comprising at least one ply with a background pattern having
microprotuberances and especially, but not only, making it possible to
combine it with a pattern having macroprotuberances” (id. at 4). The
Specification discloses that using microprotuberances as the background
pattern “improve[s] the final appearance of the sheet by better highlighting
the pattern having macroprotuberances . . .” (id.).
DISCUSSION
1. CLAIMS
Claims 1, 3-10, 23, and 24 are on appeal. Claims 12-22 are also
pending but have been withdrawn from consideration by the Examiner.
Claim 1 is representative and reads as follows:
1. An embossed sheet comprising at least one ply of
creped cellulose wadding with a basis weight of between 12
and 30 g/m2 having an embossed pattern comprising at least a
first series of protuberances formed so as to project from one
face of the ply and the density of which is greater than 20
protuberances per cm2, characterized in that each protuberance
of the first series comprises a truncated polyhedron-shaped base
and a flattened free-end portion with rounded edges.
Thus, claim 1 is directed to a sheet that has an embossed pattern
comprising more than twenty protuberances per square centimeter. Each
