A fluid transfer assembly comprises a housing for accommodating a fluid. A bellows member disposed in the housing defines an opening therethrough adapted to be in fluid communication with an applicator assembly. The bellows member is adapted to operatively engage the applicator assembly for extension in a first direction and contraction in a second direction. The bellows member seals against the inner surface of the housing during extension and contraction for defining a variable volume chamber with the housing. Expansion of the bellows member in the first direction reduces the chamber volume for generating positive pressure in the housing and forcing fluid through a valve to the applicator assembly. Contraction of the bellows member in the second direction increases the chamber volume for generating negative pressure within the housing for drawing fluid into the chamber.

A device for applying a mixed component includes first and second component reservoirs, a static mixing nozzle configured to mix first and second components into the mixed component, a component passage disposed between the component reservoirs and the first end of the static mixing nozzle, the component passage disposed to enable the first and second components to flow from the reservoirs to the static mixing nozzle, a spray tip including an air inlet disposed at least partially between the first end of the spray tip and the second end of the spray tip, the first end of the spray tip being disposed adjacent the second end of the static mixing nozzle, a component applicator configured to use air to apply the mixed component through the second end of the spray tip, and a trigger mechanism disposed on the component applicator, and configured to enable application of the mixed component.

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