Abstract: 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.

Abstract: The present invention relates to an intravaginal tampon for feminine hygiene includes a generally cylindrical absorbent pledget and a withdrawal element operatively connected to the generally cylindrical pledget proximate to the withdrawal end thereof. The absorbent pledget includes a mass of fibers compressed into a self sustaining shape and a sheet-like fluid-permeable cover substantially enclosing the mass of fibers. The absorbent pledget has formed thereon or therein at least one continuous groove form comprising a plurality of substantially longitudinal groove segments linked only to form a turn located alternatively proximate the insertion end and withdrawal end and wherein the continuous groove form extends around at least 180° about the circumference of the generally cylindrical absorbent pledget.

The absorbent pledget includes a mass of fibers compressed into a self sustaining shape and a sheet-like fluid-permeable cover substantially enclosing the mass of fibers. The absorbent pledget has formed thereon or therein a plurality of detached groove forms. At least two of said detached groove forms each has a length, measured along the groove, that is at least 150% of the length of the pledget; each has a major axis having a generally longitudinal orientation; and each has a turn proximate to at least one of the insertion end and the withdrawal end.

Abstract: Sensor particles comprise a silica-based core and at least one photoluminescent dye. The silica-based core may comprise a plurality of pores and the at least one photoluminescent dye may comprise a reference dye, insensitive to its environment and analytes and a sensor dye, sensitive to either or both of the foregoing. The sensor particles may be employed to sense unknown environmental conditions or analytes in biological or non-biological systems, in vitro or in vivo.
