Barrier means
First Claim
1. A barrier means for connection to a body part to prevent the body part from becoming wet when liquid is externally applied to or near the body part, the barrier means comprising:
- a web formed of flexible and liquid impervious material and having two surfaces and a periphery;
a strip of liquid impervious adhesive extending about the periphery on one surface of the web for connecting and sealing the periphery of the web to the body part;
the web being dimensioned and shaped so that the area of said one surface of the web is greater than the area of the footprint of the web thereby providing slack in the web when the web is connected and sealed to the body part, whereby the slack reduces the magnitude of tensile forces created in the web in response to movement of the body part and adjacent body areas to a level below that necessary to pull the periphery of the web away from the body part.

Abstract
A barrier means (2) for connection to a body part to prevent wetting of the body part when liquid is externally applied to or near the body part comprising a web (4) formed of flexible and liquid impervious material and a strip (6) of liquid impervious adhesive extending about the periphery (8) on one side (10) of the web (4) for connecting and sealing the periphery (8) to the body part. The web (4) is dimensioned and shaped so that the surface area of one side (10) of the web (4) is greater than the area of the footprint of the web. This can be achieved by providing corrugations (12), pleats (20), folds (22), or a receptacle (24) in the web (4). Because the surface area of side (10) is greater than that of the footprint of the web, slack is formed in the web. The provision of this slack reduces the magnitude of tensile forces created in the web in response to movement of the body part and adjacent body parts to a level below that required to pull the periphery (8) away from the body. This ensures that a seal about the web (4) is always maintained thereby preventing the body part from becoming wet on the external application of liquid, for example, when bathing or showering.

21. A barrier means for connection to a body part to prevent the body part from becoming wet when liquid is externally applied to or near the body part, the barrier means comprising:
-
a web formed of flexible and liquid impervious material; a strip of liquid impervious adhesive extending about the periphery on one side of the web for connecting and sealing of the periphery of the web to the body part, the adhesive strip having at least one discontinuity bound by respective opposite edges, so that when the web is connected to the body part by contacting the adhesive strip in such a manner that the distance between the respective opposite edges is decreased thereby creating a corrugation in the web, the surface area of the web as applied is greater than that of the footprint of the web as applied, thereby providing slack in the web when the web is connected and sealed to the body part, whereby the slack reduces the magnitude of tensile forces created in the web in response to movement of the body part and adjacent body areas to a level below that necessary to pull the periphery of the web away from the body part.
