Abstract: A cartridge holder is capable of receiving a first type of cartridge and a second type of cartridge containing viscous material. The cartridges of the first type are different in size from the cartridges of the second type. The cartridge holder has a distal stop for receiving a dispensing end of the cartridges and a proximal receptacle for receiving a rear end of the cartridges. The receptacle is located opposite to the distal stop along a longitudinal axis of the cartridge holder and is movable along the longitudinal axis as well as spring loaded towards the distal stop. Furthermore, the receptacle is configured to contact the rear end of the first type of cartridges at a smaller distance from a rear end of the receptacle than the rear end of the second type of cartridges.

Abstract: A dispenser for dispensing materials includes a dispenser body, a driving rod movable relative to the dispenser body and into the receptacle, a trigger lever having an actuation member for displacing the driving rod upon rotation of the trigger lever around a rotation axis, and a pivot member that rotatably connects the trigger lever to the dispenser body and defines the rotation axis. The pivot member is movably connected to the trigger lever such that a lever distance between the rotation axis and the actuation member changes upon movement of the pivot member relative to the trigger lever. The dispenser includes an adjustment mechanism for adjusting a mechanical advantage of the trigger lever by changing the lever distance and to adjustably fix the lever distance to at least a minimum distance and a maximum distance.

Abstract: A distributor head for a distributor apparatus for distributing fluids onto a surface includes an elongate base element having a fluid volume to receive the fluid, a filling opening connected in a fluid-communicating manner to the fluid volume to fill the fluid into the fluid volume, and a plurality of distributor openings connected in a fluid-communicating manner to the fluid volume to distribute the fluid from the fluid volume. The filling opening arranged at a first longitudinal side of the distributor head and the plurality of distributor openings arranged at a second longitudinal side of the distributor head, the first longitudinal side arranged opposite the second longitudinal side, and the plurality of distributor openings continuously formed in a wall of the base element.
