Autoinjector with multichamber product container

An autoinjector for discharging one or more liquid products, comprising:

• a housing;
• a multichamber product container arranged in the housing and comprising a syringe body and an injection needle rigidly coupled to a distal end of the syringe body, wherein the syringe body comprises a first chamber configured for a first liquid product, a second chamber configured for a second liquid product, and a bypass for fluidically connecting the first chamber and second chamber, wherein the bypass is formed in or on the syringe body as a curved section protruding radially outward, wherein a first plunger and a second plunger are arranged in the syringe body in an axially movable manner, wherein the first liquid product and the second liquid product in an initial position of the autoinjector are separated from one another by the second plunger, and wherein the first plunger and/or the second plunger are movable in a discharge direction in order to discharge the product contained in the multichamber product container or the plurality of products contained in the multichamber product container;
• a drive element configured to act on the first plunger during a discharge of the product;
• and
• a first spring configured to act on the drive element, wherein a bias of first spring is sufficient such that the first spring is configured to discharge the liquid product or the plurality of liquid products out of the second chamber of the multichamber product container by moving the drive element by a discharge stroke;
• and
• a multichamber product container holder fixedly arranged in the housing,
• wherein the housing or the multichamber product container holder comprises a cutout within which the bypass is received, the cutout configured with a distal stop and a proximal stop that axially fix the bypass such that the multichamber product container is axially fixed in the housing or in the multichamber product container holder.
