ABSTRACT:
A dual chamber flexible tube dispensing package is formed by providing a pair of plastic parisons, blow molding each parison to form a tube having a rigid finish, a shoulder adjacent the finish and a flexible body extending from the shoulder with a closed lower end; each tube having a generally D-shaped cross section throughout the finish, shoulder and body; each tube having an arcuate wall and a generally flat wall; and bringing the flat walls into abutting relationship. Each tube has a thread such that when the flat walls are in abutting relation, the thread on one tube form continuous thread with the thread of the other tube. In another form of dual chamber dispensing package, each tube has a plurality of vertically spaced integral ribs which extend transversely. The ribs on one tube are staggered relative to the ribs on the other tube so that when the tubes are brought into engagement, the ribs on one tube engage the ribs on the other tube and the shoulders are in abutment.
