First Claim
1. A sanitary napkin, comprising:
- (A) a liquid-absorbing section for absorbing bodily exudate, said liquid-absorbing section having;
(i) two opposing longitudinal sides;
(ii) a first transverse side defining a front portion of said liquid-absorbing section;
(iii) a second transverse side opposing the first transverse side, the second transverse side defining a rear portion of said liquid-absorbing section;
(iv) an imaginary longitudinal centerline; and
(v) an imaginary transverse centerline;
said liquid-absorbing section comprising;
(i) a liquid-permeable cover layer, the cover layer having an external surface facing towards a wearer'"'"'s body when the napkin is in use by the wearer;
(ii) a liquid-impervious barrier layer, the barrier layer having an external surface facing away from the wearer'"'"'s body when the napkin is in use by the wearer;
(iii) an absorbent layer intermediate the cover layer and the barrier layer;
(iv) adhesive material on the external surface of the barrier layer, the adhesive material capable of releasably adhering the liquid-absorbing section to an undergarment of the wearer when the napkin is in use;
(B) a liquid-arresting section united with said liquid-absorbing section, said liquid-arresting section projecting rearward from the second transverse side of said liquid-absorbing section to a sufficient distance to at least partially cover a wearer'"'"'s gluteal groove when the liquid-absorbing section is substantially aligned with the wearer'"'"'s vaginal opening, the liquid-arresting section having an external surface facing away from the wearer'"'"'s body when the article is in use by the wearer, the external surface being substantially free of adhesive; and
wherein said liquid-arresting section has a longitudinally extending preferential bending zone, such that when the article is in use by the wearer, at least a portion of said liquid-arresting section is capable of bending at said preferential bending zone so as to enter the wearer'"'"'s gluteal groove.

Abstract
The present invention is directed to a sanitary napkin having a liquid-absorbing section with two opposing longitudinal sides; a first transverse side which defines a front portion of the liquid-absorbing section and a second transverse side opposing the first transverse side which defines a rear portion of the liquid-absorbing section. The liquid-absorbing section includes a liquid-permeable cover layer, a liquid-impervious barrier layer and an absorbent layer intermediate the cover layer and the barrier layer. The napkin further includes a liquid-arresting section united with the liquid-absorbing section, the liquid-arresting section projecting rearward from the second transverse side of the liquid-absorbing section to a sufficient distance to at least partially cover a wearer'"'"'s gluteal groove when the liquid-absorbing section is substantially aligned with the wearer'"'"'s vaginal opening. The liquid-arresting section has an external surface facing away from the wearer'"'"'s body when the article is in use by the wearer, the external surface being substantially free of adhesive. The liquid-arresting section has a longitudinally extending preferential bending zone, such that when the article is in use by the wearer, at least a portion of the liquid-arresting section is capable of bending at the preferential bending zone so as to enter or conform to the wearer'"'"'s gluteal groove.
