Patent number: 5861348Abstract: The present invention provides a body-adhesive tape having adhesive properties preventing the tape from peeling off due to sweat when it is applied in an overlapped manner, and which also has good moisture permeability. In the body-adhesive tape, a base cloth is formed from a stretchable warp thread and a standard weft thread. On one side of the base cloth a plurality of pressure-sensitive adhesive layers are formed separated by appropriate gaps. The pressure-sensitive adhesive layers are formed so that they meander left and right along the length of the tape. At the gaps, the base cloth is exposed so there is permeability. Since the gap meanders, it is longer than the tape, and thus there is more exposure of the weave and more permeability. The pressure-sensitive adhesive layers meander so that the tape can be attached anywhere on the body and can respond to tension due to body movement from any direction.Type: GrantFiled: September 19, 1996Date of Patent: January 19, 1999Assignee: Kinesio Co., Ltd.Inventor: Kenzo Kase
