Patent number: 9125481Abstract: A massage brush (10) includes a base plate (12) that is curved in a rounded shape, a plurality of pressing protrusions (13) that protrude downward from the concave-shaped inner surface of the base plate (12), and a grip portion (20) that is connected to the center portion of the convex-shaped outer surface of the base plate (12). The base plate (12) is provided with a plurality of tongue-like sections (14) arranged at intervals in a circumferential direction and extending outward in a radial direction from the center portion of the base plate (12). The tongue-like sections protrude in a cantilever shape from base end portions (15) of the center portion by the presence of U-shaped through grooves (16) provided around the tongue-like sections other than the base end portions (15). The pressing protrusions (13) protrude downward from the tip portions of the tongue-like sections (14).Type: GrantFiled: September 15, 2010Date of Patent: September 8, 2015Assignee: Kao CorporationInventors: Toshio Watanabe, Keiji Yoshii

Patent number: 8394134Abstract: A heat generating device includes an air-permeable first side located proximal to a wearer's body, a second side located distal to a wearer's body, and a heat generating member between the two sides. The second side includes an adhesive layer for attaching the device to a garment. The first side is formed of a nonwoven fabric having an uneven surface topography. The nonwoven fabric includes a first fiber layer, inclusive of a first surface of the fabric, and a second fiber layer, inclusive of a second surface of the fabric, partly bonded to each other and including a large number of protrusions and recesses on the side of the first fiber layer. The first surface is used as the first side.Type: GrantFiled: February 8, 2008Date of Patent: March 12, 2013Assignee: Kao CorporationInventors: Yuki Hidaka, Atsushi Suzuki, Ichiro Sakamoto, Keiji Yoshii
