Abstract:
1. A dispenser for dispensing a substance, comprising: a body including a variable-volume storage chamber for storing the substance; a dispensing portion connected with the body and defining a dosage chamber coupled in fluid communication with the storage chamber for receiving substance therefrom, and an outlet aperture coupled in fluid communication with the dosage chamber; a first valve forming an external portion of the dispenser and including a valve seat and a flexible valve cover seated on the valve seat defining an interference fit therewith and defining a normally-closed seam therebetween forming a fluid-tight seal between the valve cover and valve seat, wherein the flexible valve cover is movable relative to the valve seat and the seam is connectable in fluid communication with the outlet aperture to allow the passage of substance through the seam and out of the dispenser; a second valve coupled in fluid communication between the dosage chamber and the storage chamber that allows the flow of substance from the storage chamber into the dosage chamber and substantially prevents the flow of substance from the dosage chamber into the storage chamber; and an elastic actuator mounted on the dispensing portion and movable between (i) a first non-actuated position, and (ii) a second actuated position for compressing a dose of substance within the dosage chamber and, in turn, dispensing the substance through the first valve, wherein the actuator is configured to be actuated in a direction between the first non-actuated position and the second actuated position that is transverse to an axis of the first valve, the elasticity of the actuator causes the actuator to return from the second actuated position to the first non-actuated position upon releasing the actuator, and the actuator is in fluid communication with the dosage chamber, extends axially in a direction approximately parallel to an axis of symmetry of the dispenser, extends angularly about the axis of symmetry, and in the second actuated position extends into the dosage chamber.
