发明名称 Multichamber squeeze tube integrally molded in one piece and container assembly incorporating same
摘要 A container for dispensing two flowable products in desired proportions includes a multichamber squeeze tube with a pair of nested tubes integrally molded with an end wall as a single piece. Apertures in the end wall provide dispensing openings for a first chamber inside the inner tube, and for a second chamber between the two tubes. Preferably, the two tubes have out of round cross-sections, generally ellipsoidal in configuration, and the outer tube has a cylindrical neck with a shoulder joining it to the out of round main section. The out of round inner tube extends up into the neck of the outer tube to the end wall and is integrally molded along a major axis to the shoulder of the outer tube. The single piece, two chamber squeeze tube is molded in a straight draw mold with a split mold piece only required to release external threads formed on the neck. A cap with internal threads screws onto the threaded neck.
