Abstract: Provided are absorbent sanitary protection products for direct attachment to the skin and hair of a user. The products comprise an absorbent core, a barrier layer coupled to one side of the core and a pressure sensitive adhesive layer on the side of the core that faces the body of a user. The pressure sensitive adhesive has sufficient adhesive strength to enable the product to adhere securely to the skin and hair of the user and yet to be removed without pain or trauma. Products described include those that are restricted to covering and adhering to the perineal area as well as those having ancillary structures to attach to body structures beyond the perineal area. Additionally disclosed is a packaged arrangement of the products of the invention for which little or no release paper is required.

Abstract: An apparatus and method is provided for simultaneously measuring the liquid absorbent capacity and the wetting rate of absorbent structures as a function of volume and time. These absorbency characteristics can be measured at a zero or a negative hydrostatic head, where the absorbency characteristics are due only to the liquid drawing power of the absorbent structure, or at a positive hydrostatic head. The device comprises: a liquid reservoir for holding a column of liquid where the reservoir has an opening at its bottom and is closed at the top; an orifice plate having a liquid delivery orifice which is in flow communication with the opening in the reservoir through a flow communication means; an air bleed orifice in the liquid reservoir between the top and bottom thereof and in fluid communication with the atmosphere; and a means for adjusting the relative heights of the air bleed orifice to the orifice plate.
