A unit dose dispensing collapsible tube adapted to dispense a viscous liquid therefrom includes a collapsible tube portion and a unit dose dispenser. The unit dose dispenser includes a cap member on the collapsible tube portion, and a closure element connected to the cap member. The cap member has an opening therein to provide a path of flow for the viscous liquid in the collapsible tube portion from the collapsible tube portion to the unit dose dispenser, and an indentation therein to define a unit dose-measuring section adapted to hold a unit dose of a viscous liquid. The closure element has a lower surface with a configuration complementary to the bottom surface of the unit dose-measuring section of the cap member and a passageway therethrough in fluid flow communication with the viscous liquid in the collapsible tube portion and the unit dose-measuring section. The closure element is capable of movement between an open position in which the viscous liquid flows from the collapsible tube portion through the passageway to the unit dose-measuring section of the cap member, and a closed position in which the viscous liquid is dispensed from the unit dose-measuring section of the cap member.
