Abstract
A sanitary-pad roll includes a core and a strip that is wrapped around the core. The strip, when unrolled, extends along a longitudinal direction that is perpendicular to a transverse direction. In addition, the strip includes an impermeable layer, an absorbent layer, and a weakened region that extends along the transverse direction and defines segments that are detachable from the strip. These segments, when detached, form corresponding sanitary pads. The impermeable layer, which is wider than the absorbent layer, is folded over along the longitudinal direction to form an overlap, thereby enclosing the absorbent layer.
Claims27
A manufacture comprising a sanitary-pad roll, said sanitary-pad roll comprising a core and a strip wrapped around a core, said strip extending along a longitudinal direction that is perpendicular to a transverse direction and comprising an impermeable layer, an absorbent layer, and a weakened region that extends along said transverse direction and defines attached segments that, when detached from said strip, form corresponding sanitary pads, wherein said attached segments include a distalmost attached segment, said distalmost attached segment being attached to only one other attached segment, wherein said impermeable layer, which is wider than said absorbent layer, is folded over along said longitudinal direction to form an overlap, wherein said impermeable layer comprises a backing material that is bonded to itself along said longitudinal direction to form said overlap, wherein said backing material and transverse bonds that extend across an inter-pad space between adjacent ones of said segments form individual compartments for each of said sanitary pads, each of said compartments being a sealed compartment that extends between said transverse bonds, whereby, as a result of being within said compartment, said segments, including said distalmost attached segment, are prevented from having an exposed transverse edge and said sanitary napkins in said compartments are protected from becoming wet and contaminated.

A method comprising making a roll of sanitary pads, wherein making said roll comprises making a strip of said sanitary pads, wherein said strip extends along a longitudinal direction that is perpendicular to a transverse direction, wherein said strip comprises an impermeable layer that comprises a backing material, an absorbent layer and a weakened region that extends along said transverse direction and defines attached segments, each of which contains a sanitary pad therein, wherein said impermeable layer is wider than said absorbent layer, wherein said attached segments include a distalmost attached segment, said distalmost attached segment being attached to only one other attached segment, wherein, between each pair of adjacent segments, there exists an inter-pad space across which said backing material extends, folding said impermeable layer along said longitudinal direction to form an overlap, bonding said backing material to itself, forming a sealed compartment around each of said segments, including said distalmost segment, wherein each of said sealed compartments protects a corresponding one of said sanitary pads from wetness and contamination, wherein forming said sealed compartments comprises, for each segment, forming a transverse bond across each of said inter-pad spaces adjacent to said segment, whereby each of said compartments extends between a corresponding pair of said transverse bonds, and wrapping said strip around a core.
