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.
