Abstract A sanitary napkin provided with improved pressure sensitive adhesive means for attaching the napkin to a supporting garment. The adhesive is applied to the bottom surface of the napkin and comprises at least two narrow parallel lines covered by a single overlying protective release sheet. Each strip has substantially less width and total surface area when compared with the width and area of adhesive strips or patches formerly used for attachment purposes. A typical adhesive pattern applied to an 8 X 2 5/8 in. napkin comprises a pair of centrally disposed parallel strips, each strip being approximately 6 in. long and one-eighth in. wide, and spaced about three-eighth in. from each other. The two strip pattern uses less adhesive, yet is more effective in preventing displacement of the napkin and in counteracting the shear forces exerted on the napkin by normal leg motion. The arrangement prevents failure of the wrapper when the protective sheet is removed by the user. It also reduces considerably the incidence of adhesive transfer to the garment at the time when the napkin is removed from the garment for disposal.
In an elongate sanitary napkin structure provided with means for attaching said napkin to a supporting garment in which said means comprises pressure sensitive adhesive disposed on the bottom surface of said napkin comprises a pad of absorbent material enclosed in a fluid pervious non-woven wrapper comprising a substantially rectangular sheet enveloping said pad and overlapped on the bottom side thereof, the improvement wherein said adhesive comprises at least two narrow lines of adhesive parallely spaced from each other and extending longitudinally of said bottom surface, said spaced lines being centrally disposed thereon with respect to the sides and ends thereof, and said lines of adhesive penetrate both of said overlapped portions of said wrapper.
