  • Extrusion blow-molded squeezable tube-shaped container and method for making same
    Patent number: 6673301
    Abstract: A squeezable tube-shaped plastic container (10, 100) having a one-piece construction formed by extrusion blow-molding techniques. The container (10, 100) has a retractable end wall (26, 126) which is positionable into an outwardly projecting position and an inverted position. The end wall (26, 126), as blown, is in the outwardly projecting position and is thereafter inverted so that a tamper indicating covering (28, 128) can be attached to the end (14, 114) of the container (10, 100) thereby sealing the end wall (26, 126). The inverted end wall (26, 126) permits the container (10, 100) to be free standing on the standing ring (20, 120). In use, the flexible sidewall (12, 112) of the container (10, 100) is squeezed to snap the end wall (26, 126) from the inverted position to an outwardly projecting position to enable ready access to a dispensing opening (32, 132) on the end wall (26, 126).
