## Abstract

A dispenser with adjoined dual tubes for providing a combination of ingredients which remains separate from each other during storage. The compartments, at one end, taper to a restricted opening adjacent to each other. Each of the openings has a shape generally of a D, with the straight ends of the D's lying next to each other. The tapering of the openings creates a nozzle of these orifices. This tapering nozzle then fits directly into a single opening in the bottom section of a hinged cap. From there they dispense the product directly. In their manufacture, for example through extrusion-blow molding, the bottom ends of the two compartments connect to an integrally formed plenum. This common plenum facilitates the molding of the dispenser from a thermoplastic. The finishing of the tube involves the removal of the common plenum. After filling, the bottoms of the two tubes may undergo heat sealing to close them and to connect them together.
