Abstract: The invention relates to a hand-operated dispenser (1) for highly viscous to fluid substances with a pumping chamber (17) and with at least one outlet valve (12) and a storage chamber with a feeding piston (5), wherein the dispenser (1) is designed for the output of two different substances, a first substance (4) and a second substance (22). The second substance (22) is brought out by the pressure of the first substance (4). To develop a dispenser of this type for most efficient use, it is proposed that a movable separating body (T) be arranged between the first substance (4) and the second substance (22).

Abstract: A dispensing pump made of plastic for dispensing paste-like materials from a paste container. It is provided with a bellows, which connects an upper housing part to a lower housing part. The housing parts are guided telescopically in one another. A paste channel is located within an annular wall. A second hollow body is inserted into the upper housing part, and the second hollow body forms the paste storage space, which is in connection with the paste channel and in which an elastic diaphragm wall having a plug-like closing member is arranged.
