Tampon with penetrating groove segments
View Patent ↗The present invention relates to an intravaginal tampon for feminine hygiene. In particular, it relates to methods for producing such a tampon having relatively deep, penetrating grooves in which adjacent penetrating jaws pass through the same tampon press space during manufacture and to an apparatus useful in making such a tampon as well as the tampons made therewith.
1. An intravaginal tampon for feminine hygiene comprising:
a) a generally cylindrical absorbent pledget, substantially enclosed in a cover, having a length, a longitudinal axis, an insertion end, and a withdrawal end and comprising
i) a mass of fibers compressed into a self sustaining shape and
ii) a sheet-like fluid-permeable cover substantially enclosing the mass of fibers;
b) a withdrawal element operatively connected to the generally cylindrical pledget proximate to the withdrawal end thereof;
wherein the absorbent pledget comprises at least one groove form on the outer surface of the compressed tampon pledget, wherein the groove form has a turn comprising an intersection of at least two groove segments having a depth of at least about 0.7 mm proximate to one end of the compressed tampon pledget.
2. The tampon of claim 1 wherein the turn of the at least one groove form is disposed proximate to the insertion end of the pledget.
3. The tampon of claim 1 wherein the turn of the at least one groove form is disposed proximate to the withdrawal end of the pledget.
4. The tampon of claim 1 wherein the at least one groove form has a turn disposed proximate to each of the withdrawal end and the insertion end of the pledget to form a discrete surface zone bounded by such groove form.
5. The tampon of claim 1 wherein the at least one groove form has at least one turn disposed proximate to each of the withdrawal end and the insertion end of the pledget to form plurality of interconnected longitudinal groove segments disposed about the outer surface of the pledget.
6. The tampon of claim 1 wherein the pledget comprises at least one additional groove disposed between two groove forms.
7. The tampon of claim 6 , wherein the at least one additional groove is oriented substantially longitudinally.
8. The tampon of claim 1 substantially contained within an applicator.
