Abstract
A dual-chambered dispenser is provided including a pair of elongated hollow tubes containing separate flowable material streams, a manifold for directing the flow through separate chambers, a cap fitting over dispensing openings of the manifold and a metering valve located within the manifold downstream from the dispensing openings. The valve is present to adjust differences in flow rates between the two material streams. In a preferred embodiment, the tubes are juxtaposed along their respective flat outer walls which may include a series of ribs/depressions allowing for coupling of the tubes and strengthening the flat walls against collapse relative to other wall areas of the tubes. Advantageously the valve is a duckbill type and the tubes taper in a pear shape, the broader portion being near the open end of the tubes.
