Abstract
An improved wrapper structure for tampons containing superabsorbent material. The wrapper provides the used tampon with a fluid-lubricated surface to ease withdrawal. The wrapper is a fluid-permeable web material having a saline fluid retention capacity sufficient to partially counteract the high capillary suction pressure exerted by superabsorbent fibers in the tampon core and thereby retain enough fluid in the wrapper during use to maintain the surface fibers of the wrapper in soft, lubricous condition.
Claims7
In a tampon comprised of an absorbent core containing superabsorbent materials and a fluid-permeable wrapper enclosing said core and in which said superabsorbent material has a suction pressure in the range of 25 cm. of H.sub.2 O or more when 5 ml. of physiological saline fluid are absorbed per gram of fiber, means for providing ease of withdrawal of the tampon comprising a body fluid lubricable wrapper material having a fluid retention capacity of 30% or more, said fluid retention capacity being the percent saline solution retained in the wrapper material at equilibrium conditions when said wrapper is in simulated contact with a superabsorbent material containing 100% saline solution by weight.
