Title:
Multilayer protective coverings with a sealing solution
Document Type and Number:
WIPO Patent Application WO1992017125
Kind Code:
A3
Abstract:
A protective covering, such as a surgical glove, having two layers sandwiching a layer of protective solution, such that if the covering becomes punctured or torn, the substance releases to protect the user. The liquid layer has an average thickness of less than about 0.12 mm, such that it exerts a capillary force on the two glove layers, thereby providing a mechanical-like coupling effect. The protective solution may include a dye for a visual indication of punctures or tears in the outer layer. The layers may be adhered together at desired points to restrict the layers from peeling apart during use. Various methods for making such protective coverings are disclosed.
