Claim 0:
1. An absorbent core (101) comprising:
a front portion (122);
a back portion (124);
a crotch portion (126) positioned between the front portion (122) and the back portion (124); and
a longitudinal axis extending along a length of said core (101) and crossing said front, crotch and back portions (122, 126, 124), the absorbent core (101) having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends (102, 103) and at least two opposing sides (104, 105) positioned between said ends (102, 103) characterized in that the absorbent core (101) comprises one or more substantially interconnected channels (106) extending through the crotch portion (126) along and substantially parallel to the longitudinal axis and further extending along at least a portion of said width of the core from one side of the core to the other, wherein said one or more substantially interconnected channels (106) are substantially free of three-dimensional absorbent material and comprises a first nonwoven web bonded to a second nonwoven web by one or more adhesives, and wherein each substantially interconnected channel (106) comprises:
a first channel portion (107) extending substantially along the longitudinal axis proximal to a first side (104) of the core (101);
a second channel portion (108) extending substantially along the longitudinal axis proximal to a second side (105) of the core (101); and
at least one connecting channel portion (109) in fluid communication with said first and second channel portions (107, 108), and wherein the connecting channel portion (109) extends substantially along the width of said core (101) forming a closed end shape within a surface of said core (101) along a plane parallel to the longitudinal axis, said closed end being substantially curvilinear in shape forming a convex shape between the first and second channel portions (107, 108).
