Abstract
Abstract A dispenser for the individual portioned dispensing of tablets (1), pastes or the like, having a housing pipe (2) which is provided at one end with a delivery opening (6) and, opposite same, is equipped with a push bottom (13) for transporting of the material to be dispensed in the direction towards the delivery opening (6), which push bottom (13) can be displaced stepwise in the direction towards the delivery opening by means of an actuating handle which is adjacent the delivery opening and is connected to the push bottom. In order to obtain a favorable accommodation for the material to the dispensed, the bar connection between actuating handle (9) and push bottom (13) extends along the inner surface of the housing pipe wall, leaving the inside of the housing pipe (2) free.
