Patent number: 11744304Abstract: To configure a pad so as to be gentle to the skin, to prevent stretching and/or tearing of the front surface sheet, and to not reduce liquid permeability and air permeability. [Solution] An underarm sweat pad in which an absorbent is interposed between a front surface sheet and a back surface sheet and which is used folded in two at a folding line and attached to the inside of the axillary portion of a garment. The front surface sheet is composed of a hydrophilic cellulose fiber. Adhesive regions, in which an adhesive for bonding the front surface sheet to the absorbent is applied, are formed as stripes that are parallel to the folding line and are spaced at intervals in the direction that is orthogonal to the folding line.Type: GrantFiled: August 28, 2019Date of Patent: September 5, 2023Assignee: DAIO PAPER CORPORATIONInventor: Ryoko Kurihara
