A paint applicator, kit and methodology for using the same is disclosed. For example, a paint applicator that allows a user to load a desired amount of paint, such as a water based or other low VOC paint, into the paint applicator and an advancement mechanism that dispenses paint at a rate controllable by the user is disclosed. The advancement mechanism can include a system that translates a rotational force applied to an end cap of the applicator into a linear force that advances a piston which in turn applies paint to an applicator portion. The paint applicator may be reusable or may include a ratchet system that allows for only one time use. The methodology and kit can incorporate a syringe for loading paint into the paint applicator, thus reducing the loss of paint through spilling.

A dispensing system (2000), includes a container (900) containing a flowable base formulation (910) to be dispensed, an additive mixing device (2004), and an actuable pump engine (2002) which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body (2022) with an internal cavity (2052), an additive ingredient (2054) within the cavity, and a flow path/mixing chamber (2058) between an input and an output. With each pump of the device (2004) the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices (2004) may be interchangeable for different formulations, and the mixing devices may be refillable.

An example fluid applicator device includes an applicator assembly, and a reservoir assembly configured to store a fluid and is rotatable, relative to the applicator assembly, to control a valve mechanism that controls a flow of the fluid from the reservoir assembly to the applicator assembly, wherein the applicator assembly is configured to apply the fluid to a surface.

A pneumatic paint brush feeder apparatus for supplying paint on demand to a brush includes a paint container having a top side with a fill aperture extending through to a reservoir. A lid seals and alternatively unseals the fill aperture. A battery powered compressor is coupled to the paint container and an air line extends from a compressor tank into an intake aperture of the paint container to pressurize the reservoir. A hose extends through an outlet aperture of the paint container to deliver the paint to a distal end of the hose. A brush is coupled to the hose and has a delivery tube extending from a bottom end of a handle, through a head and into a plurality of bristles to deliver paint into the bristles. A button is coupled to the brush to prevent, or alternatively allow, the flow of paint to the bristles.

A system for finishing surfaces with a finishing material includes a handle assembly with proximal and distal ends. A material reservoir is mounted on the handle distal and includes an inlet and an outlet. A material applicator tool is mounted on the reservoir and receives material from the reservoir outlet. A discharge mechanism includes an extendable-retractable component or linear actuator connected to the reservoir for discharging or reloading material. Multiple embodiments utilizing different linear actuators are disclosed. An alternative embodiment includes a push-to-open valve mechanism. Additional embodiments include an adjustment mechanism on the push-to-open valve mechanism accommodating adjustment of flow of finishing compound when the push-to-open valve is engaged.

An improved hot melt glue gun with an automatic glue stick feeding structure includes a housing that is gun-shaped and that includes an inlet and an outlet. A glue stick feeding module is mounted in the housing and located adjacent to the inlet. The glue stick feeding module includes a motor connected to a casing. The casing includes a passage and a through-hole. The passage is located in the casing and intercommunicates with the inlet. The through-hole is aligned with the passage in a transverse direction. An activation module includes an activation rod reciprocatingly and movably extending through the through-hole. A micro switch is located adjacent to the activation module and is electrically connected to the motor. The micro switch is configured to be pressed by the activation rod to activate the motor. A hot melt module is mounted in the housing and located adjacent to the outlet.
