Abstract: A discharge device (1) comprising a housing (200), a container insert (300) rotatably arranged therein and a piston. A lateral cutout (205) is formed in one housing wall (204), and a lateral container opening (303) is formed in one container wall (304). In order to prevent the compound from being compressed as the compound is discharged, the lateral container opening extends continuously as far as the distal container end (302) without a region of the container wall adjoining the lateral container opening in the distal direction along the longitudinal axis. In order to make it easier to put in the compound, the wall thickness of the housing wall decreases continuously toward the lateral cutout (205). In order to prevent clogging of the piston, the cross section of the container insert widens continuously in the distal direction.
