Abstract
A container for dispensing two flowable products in desired proportions includes a multichamber squeeze tube with a pair of nested tubes and a dispensing neck on it that are integrally molded with a transverse 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. The transverse wall has an annular stepped wall portion in it between the two tubes that is generally parallel with the outer surface of the dispensing neck and has a dispensing opening through the stepped wall portion. The openings through the stepped wall are formed by parting line contact between the mold surfaces of the mold used to form the squeeze 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.
