    Abstract: A bodyside liner material for use in disposable absorbent personal care products has an average material plane and includes a plurality of raised areas extending in a z-direction from the average material plane; a plurality of apertures through the liner material; a hydrophobic treatment agent disposed on the raised areas; and a plurality of land areas disposed between the raised areas, wherein the land areas are hydrophilic. The bodyside liner material can also include a plurality of raised areas extending in a z-direction from the average material plane; a plurality of depressed areas alternating with the plurality of raised areas, wherein the depressed areas extend in the opposite z-direction from the average material plane, and wherein the depressed areas are hydrophilic; a plurality of apertures through the liner material, wherein the apertures are disposed only in the depressions; and a hydrophobic treatment agent disposed on the raised areas.

    Abstract: In one aspect a drug delivery device may include a reservoir containing a liquid drug formulation and a microneedle assembly in fluid communication with the reservoir. The microneedle assembly may include a plurality of microneedles, with each microneedle defining an open channel for receiving a drug formulation. The open channel may have a normalized hydraulic radius ranging from about 0.1 to about 0.8. The open channel may also have a liquid-to-solid interfacial energy and a liquid-to-vapor interfacial energy when a fixed volume of the drug formulation is received therein. In addition, the drug formulation and a cross-sectional geometry of the open channel may be selected and configured such that the liquid-to-solid energy exceeds the liquid-to-vapor energy as the length of the fixed volume of drug formulation is increased within the open channel.

    Abstract: A material for distributing fluid can include a first side edge, a second side edge, a first end edge, and a second end edge. The material can include a first surface and a second surface opposite from the first surface. The material can be liquid impermeable and at least one of the first surface and the second surface include at least one channel. The channel can include a channel width, a channel length, and a channel depth. The channel width can be from 0.1 mm to 2.5 mm. The channel depth can be configured such that the channel does not extend completely through the material.

    Abstract: A disposable absorbent article includes a bodyside liner, an outer cover, an absorbent body disposed between the bodyside liner and the outer cover, and a surge layer disposed between the bodyside liner and the absorbent body, the surge layer having an X-Y plane, a Z-direction, and a longitudinal direction, and a barrier extending substantially through the surge material in the Z-direction, wherein the barrier is configured to block at least one linear longitudinal fluid flow path. The surge layer can alternatively have a plurality of barriers extending substantially through the surge material in the Z-direction, wherein the plurality of barriers is configured to block a plurality of linear longitudinal fluid flow paths or all linear longitudinal fluid flow paths while allowing non-linear fluid flow paths in the longitudinal direction.
