Abstract:
Absorbent dressings, such as tampons, made from highly absorbent cellulose fibers with ion exchange properties. These fibers are obtained by phosphorylating cellulose fibers, hydrolyzing the fiber walls with acid, converting the phosphorylated fibers to the sodium salt form, mechanically refining these fibers to rupture the primary fiber wall and permit subsequent swelling or ballooning, acidifying the refined fibers to reconvert the phosphorylated cellulose into the acid form, and drying the fibers in a manner to substantially avoid appreciable hydrogen bonding.
Abstract:
A method for incorporating small but effective amounts of a volatile odor-counteracting scent or fragrance into a compressed absorbent tampon of the type which has an inserter stick removably seated in a preformed axial cavity in the base of the tampon. The method consists of introducing a minute quantity of an alcohol solution of the selected scent into the preformed cavity, placing the inserter stick in position in the cavity, and sealing the tampon and stick combination in a vapor impermeable pouch. The scent may be introduced by micro-spraying the solution directly into the cavity, or by applying the solution onto the leading end of the insertion stick before positioning the stick in the cavity. A preferred product is also defined.
Abstract:
The combination in which an absorbent tampon in compressed selfsustaining form and having a detachable inserter rod seated in its base is frictionally engaged with an outer inserter tube having a tapered insertion-aiding forward end. The tampon is of substantially uniform diameter which is not greater than the inner diameter of the tube, except for the presence of at least one small protuberance on its circumference. The protuberance is of sufficient magnitude to provide the tampon body at the point of the protuberance with a diameter slightly greater than the inner diameter of the tube, and is adapted to provide sufficient frictional resistance to prevent disassociation of the tampon and the tube during shipping and handling while permitting easy ejection and radial orientation when the combination is used for tampon insertion.
