Abstract

An extrusion device for the extrusion of single- or multi-component materials from at least one container is provided. The extrusion device includes a housing having a functional section and a manual operation section. The housing extends substantially along an axial direction. The functional section includes at least one container receptacle. The manual operation section includes a lever arrangement via which an extrusion rod arrangement can be actuated to extrude materials from the at least one container. The lever arrangement includes a lever body mounted on a rotary axis. The lever body includes a lever push arm on one side of the rotary axis and a lever grip arm on the other side of the rotary axis. The lever push arm acts in a force-transmitting manner on a drive body attached on the extrusion rod arrangement upon actuation of the lever grip arm. The lever body includes a fork which forms at least two fork sections, and a fork trunk, wherein each of the at least two fork sections each extends into a lever push arm, and the fork trunk extends into the lever grip arm.
