Abstract

Abstract A sanitary napkin is disclosed with flange sealing means for protecting the body-facing surface from dirt and deformation until the napkin is ready for use. The seal is provided by a wrapping member which extends over at least a portion of the absorbent element of the napkin. Upon folding the napkin about a transverse axis, the wrapping member is adhered to itself by an adhesive to protect the napkin.

Claim 8
Dependent Claim 35 words
The sanitary napkin of claim 1 wherein said flange portions (16, 17) extend over the edges of said napkin (10) to form a continuous, outwardly extending flange around the perimeter of said absorbent element (24).
Claim 9
Dependent Claim 23 words
The sanitary napkin of claim 7 wherein said pressure-sensitive adhesive means (32) is disposed continuously about the perimeter of said outwardly extending flange.
Claim 10
Independent Claim 172 words
A method for individually wrapping a sanitary napkin comprising: (a) providing an absorbent element having a body-facing side, an adhesive-bearing side, longitudinally extending edges and transverse edges; (b) applying an elongated wrapping member (33) having an interior surface to said adhesive-bearing side of said absorbent element (24), said interior surface being adhered with said adhesive-bearing side of said absorbent element (24), said wrapping member (33) being selected to comprise a portion that extends over a portion of said edges of said absorbent element (24) to form opposing outwardly extending flange portions (16, 17), said flange portions (16, 17) being provided with pressure-sensitive adhesive means (32, 34) disposed at a location on said interior surface of said flange portions (16, 17); and (c) folding said napkin (10) onto its body-facing side along at least a transverse axis of said napkin (10), whereupon said pressure-sensitive adhesive means (32, 24) on said location on said interior surface adheres said flange portions (16, 17) to retain said napkin (10) in its folded position prior to use.
Claim 11
Independent Claim 172 words
A method for individually wrapping a sanitary napkin comprising: (a) providing an absorbent element having a body-facing side, an adhesive-bearing side, longitudinally extending edges and transverse edges; (b) applying an elongated wrapping member (33) having an interior surface to said adhesive-bearing side of said absorbent element (24), said interior surface being adhered with said adhesive-bearing side of said absorbent element (24), said wrapping member (33) being selected to comprise a portion that extends over a portion of said edges of said absorbent element (24) to form opposing outwardly extending flange portions (16, 17), said flange portions (16, 17) being provided with pressure-sensitive adhesive means (32, 34) disposed at a location on said interior surface of said flange portions (16, 17); and (c) folding said napkin (10) onto its body-facing side along at least a transverse axis of said napkin (10), whereupon said pressure-sensitive adhesive means (32, 24) on said location on said interior surface adheres said flange portions (16, 17) to retain said napkin (10) in its folded position prior to use.
