Abstract

Abstract A flexible dispenser for dispensing the top sheet of flexible material from a sheaf or pile of flexible materials such as paper, comprising an anchor for anchoring the dispenser, for example, in the form of a flange to be interposed between the top edge of a sheaf of paper and the front wall of a receptacle containing such paper, and a flexible or partially flexible relatively elongate dispensing member as such dispenser extending over the top sheet of paper and provided near its bottom edge with friction gripping substance on the top and bottom surfaces whereby when the dispensing member is moved rearwardly away from the point of ultimate emission of the paper, it will bow into a convex configuration causing the top sheet of paper to assume a similar configuration causing it to lift away from the remainder of the material in the sheaf and become available to be grasped for removal from the receptacle.
