Abstract: A piston for dispensing a flowable component from a cartridge includes a piston having a base body and a venting element. The base body has a passage connecting a component side and an actuation side and has a passage opening. The venting element has an internal connection element and a pin which is partly arranged in the passage opening of the base body. The internal connection element and the pin are connected by a spring element. The pin of the venting element can adopt a sealing position and an aerating position. To enable a secure sealing, the spring element is configured such that it includes an angle of a maximum of 80° with the axial direction in the sealing position of the pin at a connection line to the internal connection element in the direction of an actuation side.

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.

Abstract: A dual dispensing apparatus for dispensing two flowable components having a first storage chamber for the first component, and a second storage chamber for the second component. The two storage chambers are arranged next to one another and each have an outlet for the first or the second component respectively at their distal ends. The apparatus also has a first plunger for penetrating into the first storage chamber and a second plunger for penetrating into the second storage chamber. A respective piston for dispensing the respective component is molded to each plunger and is sealingly guided by the respective wall of the storage chamber. Each storage chamber has at least one first guide element at its end remote from the outlet and each plunger has at least one second guide element adjacent to the respective piston. The first and the second guide elements are configured for mutual engagement.
