A collapsible co-dispensing tubular container for separately storing and co-dispensing two extrusible product components of substantially equal viscosity with substantially constant proportionation. The container may comprise a collapsible tubular body, a head fitment having two discharge ports which fitment is sealingly secured in one end of the collapsible body, and a longitudinally extending interior bulkhead disposed to partition the interior of the container into two compartments, one of which compartments is in fluid communication with one of the discharge ports, and the other of the compartments being in fluid communication with the other of the discharge ports. The improvement comprises a pressure responsive moveable septum disposed adjacent the head end of the container and which septum is in fluid communication with both of the compartments in the container. The pressure responsive moveable septum precipitates equalization of the pressures on the separately stored product components upon squeezing or otherwise collapsing the container which pressure equalization effects substantially constant proportionation of the product components as they are co-dispensed from the container.
