Abstract
A tampon for hygienic use comprising a generally cylindrical absorbent core having a liquid pervious cover layer on the outer surface thereof wherein the cover layer is a polymer net comprising two intersecting sets of parallel ribs and wherein each set of ribs are aligned obliquely with respect to both the main axis of the tampon and to each other. A strip of net may be bonded to one end of a strip of absorbent material and the composite spirally wound such that the net forms the outer layer. The free end of the net may overlap an underlying layer of net and be bonded thereto by heat sealing.
Claims18
A tampon for hygienic use comprising a generally cylindrical absorbent core having a central longitudinal axis and an outer surface with a liquid pervious cover layer thereon wherein the cover layer is a polymer net comprising two intersecting sets of parallel ribs and wherein each set of ribs are aligned obliquely with respect to the central longitudinal axis of the tampon and to each other, and also comprising a set of parallel ribs aligned parallel to the central longitudinal axis of the tampon and excluding ribs which lie in a direction perpendicular to the central longitudinal axis of the tampon.
A tampon comprising a strip of absorbent material having a strip of liquid pervious polymer not attached to one end and being spirally wound to form a generally cylindrical absorbent core having an outer cover layer of polymer net, wherein the net comprises two intersecting sets of parallel ribs, each of said sets being obliquely aligned with respect to each other and to the central longitudinal axis of the cylindrical core, and a set of parallel ribs aligned parallel to the main axis of the tampon and wherein the net excludes ribs which lie in a direction perpendicular to the central longitudinal axis of the tampon.
