Claims20
A tampon pledget, comprising:
- At least one bottom pad having a length that is between about 1 inch and about 4 inches, and a width that is between about 1 inch and about 4 inches;
- at least one top pad having a width of about 2 inches and a length of about 4 inches;
- a fiber weight distribution ratio of the at least one bottom pad to the at least one top pad being between about 0.75:1 and about 1.5:1;
- and
- wherein prior to folding the at least one bottom pad and the at least one top pad to form a compressed tampon pledget, the at least one top pad and the at least one bottom pad are in a chevron, diamond, circular, oval, square, or rectangle configuration, the chevron, diamond, circular, oval, square, or rectangle configuration having an overlap portion that is formed where the at least one top pad and the at least one bottom pad overlap and a plurality of non-overlap portions that are formed where the at least one top pad and the at least one bottom pad do not overlap
- wherein the chevron, diamond, circular, oval, square, or rectangle configuration is folded, compressed, and heated to form a shaped tampon pledget, the tampon pledget having insertion region having an insertion tip end and an insertion rearward end, a main body region having a main forward end and a main rearward end, and a withdrawal region having a withdrawal forward end and withdrawal rearward end, said insertion rearward end is adjacent said main forward end, and said main rearward end is adjacent said withdrawal forward end, the shaped tampon pledget has a maximum diameter of the insertion tip region and the main body region where the insertion rearward end and the main forward end meet, wherein the main body region tapers from the maximum diameter to a minimum diameter and thereafter increases to a middle diameter that is greater than said minimum diameter.
