Abstract
Abstract A device is provided for dispensing materials contained within a collapsible tube. The device includes a spring-biased movable casing which is fitted within a housing and gradually moves upward into the housing as the contents of a collapsible tube mounted within the casing is expelled. The casing is provided with opposing longitudinal slots through which extends a shaft connected to the end of a collapsible tube. The dispensing outlet of the collapsible tube is extended through an orifice in the casing end cover. The upper portion of the casing is provided with a compression spring biased against the shaft and a top casing cover. The shaft is mounted between the stationary sidewalls of the housing for rotation, and as one twists the shaft and expells the contents of the collapsible tube, the compression spring will move the casing upwardly through the housing.
