ABSTRACT:
A flexible tube and closure includes a hollow body which terminates forwardly in a closable nozzle and rearwardly in a sealed area to retain a paste-like material therewithin. An expeller is movable from the rear sealed closure towards the front opening to rearwardly squeeze the body to force the material toward the front opening. A flattened section extends rearwardly from the closure and connects to the expeller in a loop configuration to aid in grasping and functioning the device. Longitudinally extending strips including corrugations may be provided exteriorly of the body to facilitate operation of the expeller.
