ABSTRACT:
A dispenser for the simultaneous delivery of at least two paste-like products, comprising a container with a head and internally formed with two separate cylindrical chambers which lie side by side parallel to their longitudinal axes, each chamber being open towards the head and having an associated end wall which sealingly slides in a single direction towards the head. A resilient pump member under the head includes a tubular sleeve and is formed from a resiliently flexible cup-shape membrane for each cylindrical chamber of the container with the concave part facing towards these latter. An operating lever for pressing and releasing the pump member is pivoted about an axis which is fixed with respect to the container disposed perpendicular to the longitudinal axis of the said cylindrical chambers and which is turnable about the said axis from a rest position to a paste delivery position and vice versa. A delivery duct which contains two channels which are separated by a dividing partition is attached to the sleeve. It has an outlet, positioned on the head which leads to the exterior thereof.
The dispenser also includes a transverse cover element for connecting the open ends of the side-by-side chambers of the container, the said element having a respective aperture which corresponds to each cylindrical chamber.
