ABSTRACT:
The present end-lap retainer is a one-piece device having a particular configuration so as to fit snugly over the end of a pliable tube used to dispense viscous materials, such as, toothpaste, glue, ointment, etc. During the normal use process, a toothpaste user will lap or fold the bottom end of the tube when the tube becomes partially depleted. This lapping process forces the remaining paste upward toward the top of the tube for easy dispensing of its contents. The end-lap retainer device is attached to the laps or folds, holding them firmly in place, thereby preventing any unlapping or back flow of the contents when pressure is applied to the tube during dispensing.
