Abstract
A dispenser for sheet material affords the clamping action against the sheet partially dispensed from the container to maintain it in a position where it can be grasped and dispensed. The dispenser comprises a cartridge for a stack of sheet material which stack is formed by releasably adhering successive sheets adjacent opposite edges to permit the dispensing of one sheet and the grasping of the next adjacent sheet at the opening to dispose an edge of such sheet to permit the subsequent dispensing of the next sheet. The exit opening enlarges under the dispensing force applied to each successive sheet but removal of the force allows the side walls of the cartridge to return from a pivoted position to the original position, closing the opening and grasping the sheet therebetween. The cartridge is disposed within a housing which contains the cartridge during the movement of the upper or top wall while the sheets are being dispensed.
