US 5,505,720 A · Melt blown menstrual pad for application to the body

Abstract

Improved pads for application to the body to absorb body fluids are disclosed. Menstrual pads having a plurality of projections which are most preferably filled with a superabsorbent material are disclosed, as well as methods for making same. The present invention discloses the use of novel melt-blown technology to form a surface having hollow projections which are then filled with superabsorbent. The present invention is directed to menstrual pads, as well as other pads which may be placed against the body, such as bandages. In the latter, medicinal compounds replace superabsorbents as the preferred material within the projections. In certain embodiments, a wicking layer, preferably comprised of peat moss based absorbent product is disposed between a cover layer and the projections containing superabsorbent.

Dependent claims

A menstrual pad for absorbing body fluids comprising:

a) a structural layer comprised of a polymeric material defining an array of preformed, self-supporting body-surface directed productions, each projection formed by a wall having a thickness and having an outer surface corresponding to a body facing surface and an inner surface defining a cavity region, the rigidity of said wall varying across said thickness thereof, and wherein the inner surface of said wall is more rigid than the outer surface of said wall;
and
b) a fluid transport layer disposed at least over said cavity regions to define cavities between the structural layer and said fluid transport layer.

Dependencies are inferred from the claim text.
