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.

Abstract: A plastic tube with an integral finish and a twist off tab are blow molded. The twist off tab is connected to the finish of the tube by an annular groove forming a line of weakness. The tab is formed by the closing of mold halves about an extruded parison to form a flat twist off tab connected by a thin membrane to the exterior of the finish. The tab is then blow molded to form the tube. After the mold halves are opened, the twist-off tab is trimmed to provide the finished tube. The tab is formed by a conventional blow molding process without the need of a secondary operation. A plurality of blow molded corrugations are provided between annular blow molded ribs on the finish and provide added strength to the finish to facilitate removal of the tab.

Abstract: A liquid containing and dispensing package comprising a plastic container having a finish defining an opening. The finish has an outer surface and an inner surface. At least two annular rows of circumferentially spaced lugs are provided on the outer surface of the finish. The lugs in one row are staggered circumferentially with respect to the lugs of an adjacent row. A spout is provided and has an annular outer wall, an annular inner wall and an integral portion connecting the annular walls. The outer wall of the insert has an inner surface with two rows of spaced recesses for receiving the lugs on the finish. The inner wall of the spout has an inner surface formed with a spiral thread receiving groove. The insert includes an axially extending spout connected to the lower edge of said inner wall and extending above the inner wall. A combined measuring cup and closure is provided and has an annular axial wall and a base wall and a radial flange intermediate the base wall and lower end of the axial wall.
