Absorbent article with a flap and biasing spacer

Abstract

An absorbent article having a flap and a spacer wherein the flap is positioned in the rear waist portion of the article and forms a pocket. The spacer is positioned proximate the pocket opening and biases the pocket into an open position. The flap may be a laterally extending liquid impermeable flap which is fixedly secured to the article along a seam. The seam, which may be substantially U-shaped, extends between first and second terminal ends. The flap has a free edge which extends between the first and second terminal ends of the seam. The seam and free edge of the flap define the boundaries of a pocket which is formed between the flap and a topsheet of the absorbent article. The pocket has an opening extending between the first and second terminal ends of the seam. The spacer affixed to the article whereby it is disposed between the flap and the backsheet proximate, and optionally extending through, the pocket opening to bias the free edge of the flap away from the topsheet. Alternative spacer embodiments may be employed. A single spacer or two spacers positioned on opposite sides of the longitudinal axis of the article may be used to bias the pocket open. The use of a spacer which dynamically biases the flap away from the topsheet automatically adjusts the size of the pocket opening in response to relative movement between the wearer and the absorbent article. One or more hinged spacers may be employed to provide such a dynamic spacer.
