Abstract:
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.
Abstract:
A device for applying a spray coating includes at least two component cartridge, each including an aperture in fluid communication with a static mixing nozzle, and at least one paint applicator comprising a spray tip in fluid communication with the static mixing nozzle. At least one flexible hose is disposed between and in fluid communication with the spray tip and the static mixing nozzle.
Abstract:
An apparatus for dispensing a fluid comprises a housing and a resilient liner adapted to hold the fluid disposed in the housing. A fluid transfer mechanism is in fluid communication between the liner and an applicator assembly mounted on the housing for dispensing the fluid on the skin of the user. The applicator assembly includes an actuator movable relative to the housing so as to activate the fluid transfer mechanism when the actuator is reciprocated. A fluid delivery element is held in contact against skin of a user for applying the fluid onto the skin. The fluid delivery element is supported on the actuator to be movable together with the actuator by varying contact pressure with the skin. Each movement of the actuator generates continuous negative pressure within the liner for drawing fluid through the fluid transfer mechanism and collapsing the liner.
Abstract:
A present invention liquid dispenser comprises a fluid transfer body, a reservoir with plunger, and an extender selectively attachable to the reservoir; the elongated tube shaped member has at least one wall that forms a forward rim and extends in a tubular fashion to a rearward end; the at least one wall also forms a longitudinal slot for receiving the handle of the plunger, or a lever attached to said handle; and the slot is disposed to allow the handle or lever to travel when a user pushes the handle of the plunger towards or away from the fluid transfer body end of the elongated reservoir.
Abstract:
A painting system comprises a pressurized paint canister and a pressure fed paint brush or powered paint roller connectable to the pressurized paint canister. The canister includes a paint reservoir, a self-sealing gas pressure fitting in fluid communication with the paint reservoir and configured to be connected to a gas pressure source, a paint outlet in fluid communication with the paint reservoir, and a removable cap for filling the paint reservoir with paint. The brush assembly includes a main body having a handle and a brush stock and a bristle bundle secured in the brush stock. A plurality of fluid distribution members extend into the bristle assembly and are multidirectionally flexible such that the distribution members flex substantially freely with the flex of the bristles in any direction. The fluid distribution members prevent paint flow when in an unflexed state and allow flow onto the bristles only when flexed.
Abstract:
A paint applicator is provided with a handle formed with a paint-entry passage, a first housing half connected to the handle, a second housing half jointed to the first housing half and formed with a plurality of paint exit holes, a non-permeable resilient body disposed on the second housing half and formed with a plurality of apertures, a permeable foamed body, and a brush layer. The apertures are closed in normal conditions and will be opened under pressure. Paint is accumulated in a paint chamber between the first and second housing halves, and then will flow out only when the paint pressure is greater than a deformation threshold value of the non-permeable resilient body. Furthermore, since the apertures are very small and can be evenly and densely distributed over the resilient body, paint will be evenly permeated to the permeable foamed body and the brush layer.
Abstract:
A hand-held, battery powered liquid applicator (10) having an on-board reservoir (15). An electric motor drives a piston (20) in the reservoir via a pinion gear member (70) and rack gear (28). A gear shifter (68) may disengage the pinion gear member (70) from the rack gear (28). A battery compartment (78) may have a door (88) has recess to enable a user to grasp a dry cell located farthest from the door. The rack gear (28) may have modified profile teeth at the end of travel to allow the pinion gear member (70) to slip when the piston (20) is urged past the end of travel. The piston (20) may have a length substantially equal to a characteristic length of the reservoir (15). Liquid may be drawn into the reservoir by powered or manual retraction of the piston and liquid may be delivered from the reservoir to an applicator head by powered or manual motion of the piston into the reservoir.
