Absorptive article
In an absorptive article, fitting performance is improved by following the shape and movement of a body, and wrinkles in a blood discharge opening corresponding portion are eliminated and wearing comfort is improved by separating movement of each part from each other so that the blood discharge opening corresponding portion is not affected.
1. An absorptive article comprising:
an absorbing element interposed between a permeable front-surface sheet and an impermeable back-surface sheet; and
a pair of blood discharge opening corresponding portion embosses each having an arc-shaped curve in a substantially longitudinal direction of the absorptive article and being formed on a portion of the absorptive article which, when worn, corresponds to a blood discharge opening portion and a perineal region of a wearer, each of the embosses being located on a respective side of a longitudinal center line of the absorptive article and having a center of curvature on the opposite side of the center line, a front portion emboss in a substantially width direction of the absorptive article, the front portion emboss being formed on a front portion of the absorptive article with a separation distance provided in the longitudinal direction of the absorptive article from the blood discharge opening corresponding portion embosses, and a back portion emboss having a substantially inverted V-shape gradually expanding rearward to both sides from a position on the longitudinal center line, the back portion emboss being formed on a back portion of the absorptive article with a separation distance provided in the longitudinal direction of the absorptive article from the blood discharge opening corresponding portion embosses, the separation distances respectively separating the front portion emboss and the rear portion emboss from the pair of blood discharge opening corresponding portion embosses so that each of said blood discharge opening corresponding portion embosses are discontinuous relative to the front portion emboss and the rear portion emboss along the longitudinal direction of the article and across the entirety of the width of the absorbing element, the absorptive article being free of embossing therethroughout the separation distances;
the pair of right and left blood discharge opening corresponding portion embosses each have a front end portion and a rear end portion in which each of the front end portions curve toward each other and each of the rear end portions curve toward each other, and a separation width between the rear end portions is smaller than a separation width between the front end portions; and
the back portion emboss is formed such that a pair of first and second virtual lines extend from the back portion emboss across the longitudinal center line and toward the front portion of the absorptive article so as to be substantially parallel with a pair of respective first and second tangent lines that extend from the rear end portions of the pair of blood discharge opening corresponding portion embosses, the rear end portions of the pair of blood discharge opening corresponding portion embosses being directed toward the back portion emboss and each of the virtual and tangent lines being inclined relative to the longitudinal center line.
2. The absorptive article according to claim 1 , wherein
the front portion emboss is formed by an arc-shaped curve having a center of curvature closer to the front of the absorptive article than the front portion emboss itself and an angle formed by tangent lines of both right and left end portions of the arc-shaped curve is at least 90°.
3. The absorptive article according to claim 1 or 2 , wherein
in the back portion emboss, an angle formed by the embosses formed on the both sides across the longitudinal center line is less than 90°.
