Abstract
Methods, apparatus, devices and systems for mixing and dispensing multi-component materials. The mixing and dispensing may be performed using a mobile, enclosed dispenser that can be used to supply a mixed multi-component material at the point of use. In some embodiments, the components to be mixed into the multi-component material may be supplied in cartridges.

A dispenser, comprising:
- a housing;
- a dynamic mixer attached to a front end of the housing;
- a power source;
- a compartment configured to hold a first component and a second component to be mixed, the first component and the second component are of a curable multi-component material;
- a motor, wherein the motor is operably connected to the power source through a trigger switch;
- a screw, wherein the motor is operably connected to a screw such that the motor rotates the screw about an axis;
- a follower configured to move along the screw;
- a plunger operably connected to the follower such that, as the follower moves along the screw, the plunger advances into the compartment to force the first component and the second component into the dynamic mixer, wherein rotation of the screw is configured to operate the dynamic mixer as the first component and second component are being forced through the dynamic mixer.
