发明名称 Toothpaste tube roll-up retainer
摘要 A system and method are provided for rolling up a tube of toothpaste and retaining the tube in the rolled-up condition as the toothpaste is dispensed from the tube. The roll-up means is achieved by providing a bendable strip of material and integrally molding a pair of parallel spaced bendable wires with the bendable strip of material. This device is then attached to a bottom end of the toothpaste tube. The ends of the integrally molded bendable strip and wires extend past the bottom end of the toothpaste tube on both sides of the toothpaste tube, and these extending ends are foldable over the toothpaste tube end to maintain the toothpaste tube in a progressively rolled up condition as the toothpaste is dispensed from the tube.
