Abstract: A childproof closure for a dispensing apparatus (5) having first bayonet fastening means (20), wherein the closure (40, 50, 80, 100) has second bayonet fastening means (21). One of the two bayonet fastening means (20, 21) has bayonet lugs (30, 32) which can be introduced into corresponding socket elements (25, 27) of the other bayonet fastening means (20, 21). Both bayonet fastening means (20, 21) moreover have coding elements (13, 23, 35, 38) for a preset alignment of the closure (40, 50, 80, 100) and of the dispensing apparatus (5).

The securing cap (80, 100) and the closure element (40, 50) are connected cohesively strongly, but rotatably with respect to one another, by means of shape-matched elements (58, 60, 90, 120).

Abstract: A dispensing device for a multi component cartridge includes a housing in which a reception element for receiving a cartridge end of the multicomponent cartridge is arranged. The cartridge end is located at the inlet side of a first and second storage container filled with a filling mass and respectively sealed in a fluid tight manner at the cartridge end by a respective piston. A plunger arrangement and a drive arrangement for moving the plunger arrangement are arranged in the housing. A movement of the plunger arrangement in a dispensing direction can be carried out by the drive arrangement for dispensing the filling mass from the storage containers of the multicomponent cartridge. The reception element has an axis of rotation which is substantially arranged in parallel to the dispensing direction. The cartridge end pushed into the reception element can be transferred from an assembly position into a dispensing position by a rotation about the axis of rotation.

Abstract: A dispensing apparatus for mixing and dispensing multi-component masses including a multi-component cartridge or syringe having a plurality of chambers, a mixer element having a longitudinal axis and a mixer housing placed over the mixer element. The outer surface of the mixer element and the inner wall of the mixer housing have a cooperating guide element which only allows a displacement of the mixer housing at the mixer element along the longitudinal axis of the mixer element. The mixer housing is axially displaceably connected to the multi-component cartridge. The mixer housing and the mixer element are displaceable against one another in an axial direction in the closed and dispensing positions. A rotary element, the mixer housing and the multi-component cartridge have a cooperating interaction element in which the rotary element rotates such that an axial relative movement results between the mixer housing and the multi-component cartridge.

Abstract: The invention relates to a cartridge for at least two flowable components. The invention starts from a cartridge having at least two storage containers into which pistons can be inserted for dispensing components. So that the pistons cannot slip out of the storage containers again after the insertion, peripheral beads are provided at inner walls of the storage containers. To make possible cartridges which can be manufactured inexpensively and which can nevertheless be reliably sealed, it is proposed in accordance with the invention that the first inner wall has a first connection section and the second inner wall has a second connection section in which they do not have a bead. A connection web which connects the two storage containers is in this respect arranged between the first and second connection sections.
