ABSTRACT:
A dispenser for pasty compositions has a delivery tube (3) with lateral passage openings (10) for a second component of a pasty composition developed in the delivery tube (3), and an elastically reformable pump element. The delivery tube (3) is closed by a valve body (19). A piston (33) is moveable through a housing of the dispenser in emptying direction upon reforming of the pump element. The lateral passage openings (10) for the passage of the second component can be closed by the same valve body (19), and the valve body is guided by means of a shaft in the delivery tube (3). In order to obtain in a manner simple to manufacture, a dispenser for pasty composition for possible delivery of pasty composition formed of several components, particularly an esthetically pleasing stripe formation, a stepwise widening of the delivery tube cross section which is developed in the direction of flow at the height of the upper valve-disk closure. Guide ribs for mating with the valve-disk.
