摘要：
A dispenser for a pasty material has a container, a cover and a handle. The dispenser is operable by twisting the cover and the handle relative to each other in a dispensing direction for dispensing material and, alternatively, in an opposite closing direction. The container having an outlet for the material and the cover having a dispensing opening. The container and the cover are arranged relative to each other for a rotation between a closed position, in which the cover closes the outlet, and an open position, in which the dispensing opening opens the outlet. A first engagement mechanism is provided for enabling the container and the handle to engage with each other in at least one angular position during twisting in the closing direction. The first engagement mechanism further forming a freewheel mechanism with respect to a rotation in the dispensing direction. The first engagement mechanism has a first snap-stop for providing the engagement between the handle and the container and for impeded disengagement when engaged. A second engagement mechanism is provided for enabling the rotation of the container and the cover in an angular range between the closed position and the open position and restricting a rotation outside that range. The second engagement mechanism has a second snap-stop for providing the restriction between the container and the cover with respect to a twisting toward the dispensing direction and providing for an impeded disengagement when engaged in the open position. The first snap-stop provides for an impeding force to be overcome for disengagement and the second snap-stop provides for a snap-in force to be overcome for engagement. The first and second snap-stop are configured such that the impeding force is greater than the snap-in force.
