The present subject matter relates to devices, systems, and methods for applying pesticides, herbicides, and other treatment chemicals to a surface. A roller application device for use in delivery of treatment chemicals to a landscape surface includes a handle assembly having a fluid connector configured to be connected to a treatment chemical source, and a roller applicator is connected to the handle assembly but configured to rotate about an axis. The handle assembly includes a fluid dispenser configured to deliver a treatment chemical from the treatment chemical source to the roller applicator, and the roller applicator is configured to absorb the treatment chemical in an outer surface of the roller applicator and transfer the treatment chemical to a surface upon contact with the surface.

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 receptacles, a static mixing nozzle, an applicator and an operating member. The first and second receptacles are to receive first and second components, respectively. The static mixing nozzle includes a plurality of mixing elements, has a first end and a second end, and is in fluid communication with the first and second receptacles. The applicator includes a spray tip and an input for pressurized fluid, the spray tip disposed downstream of the second end of the static mixing nozzle and in fluid communication with the static mixing nozzle. The operating member is configured to control the pressurized fluid.

An applicator (12) has a pistol grip handle (14), a trigger (16), an operative portion (22), a hollow tube (18), an articulating joint (20) disposed in the hollow tube (18) between trigger/lever (16) and operative portion (22), which has a set of separately held jaws (24 and 26) with container (28) and lid (30) disposed thereon. Jaws (24 and 26) movement is controlled by the trigger/lever (16) which is attached to the lower jaw (26) via a cable/cord (40) enclosed within the hollow tube (18). Spring straps (34) control attach the jaws (24 and 26) to the hollow shaft/tube (18).

A spray roller system for application of architectural paints coating, includes an extension tube, a spray head mounted on a distal end of the extension tube, and the in-line valve with a trigger mounted on a proximal end of the extension tube, and a roller handle removable mounted on the extension tube adjacent the spray head. The spray roller system can spray and back roll a coating on a down stroke and roll on each up stroke. When the roller handle is removed from the extension tube, it can be used to hand roll sensitive wall areas. With the roller handle removed, extension tube, spray head, and in-line valve can be used as a spray extension to apply coatings in hard to reach areas.

A pack comprising: a dispenser for anaerobically curable composition; and anaerobically curable composition held within the dispenser. The dispenser has (a) a reservoir in which anaerobically curable composition is held, the reservoir having an outlet through which the anaerobically curable composition can be dispensed; (b) a dispensing pump for pumping the anaerobically curable composition from the reservoir out through the outlet.
The reservoir and pump together form an airless pump assembly. An applicator with an applicator surface, for example a roller, is in communication with the outlet, the applicator for applying to a substrate the anaerobically curable composition that is dispensed by the pump from the reservoir out through the outlet. The pack provides a convenient way of forming of applying anaerobically curable composition in a thin even layer.
