An assembly for a dispenser includes a front plate having a first tube aperture configured for securably receiving a tube within the aperture, the tube being configured to receive a container having a flowable material; a release assembly disposed on the front plate having first and second members hingingly movable about a hinge portion on each of the first and second members for partially covering the first tube aperture when the first and second members are in a closed position and for uncovering the aperture when the first and second members are in an open position. A combination includes a dispenser and the assembly releasably secured to the discharge gun. A kit includes a container having a flowable material; the dispenser having plunger; and the assembly releasably secured to the discharge gun.

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 spray applicator assembly discharges distributable product from a cartridge using low air pressure. The cartridge is held captive between a piston advancing from the rear to expel contents and a nozzle snugly attached at the front to receive expelled contents and to convert the contents into droplets by subjecting the contents to an array of focused high velocity air streams. The nozzle has an open barrel design and is able to discharge a variety of liquid or viscous distributable product without readjustment, other than resetting a proportioning valve in the low pressure air feed line. An air chamber immediately in front of the cartridge nose provides constant backpressure, which dominates to cleanly stop flow of distributable product into the nozzle whenever the piston stops advancing. When the piston resumes advancement, the flow restarts cleanly. Clean stopping and starting saves distributable product from waste. Variations in the distributable product might include, without limitation, a broad variety of materials including coating materials and combustibles.

A dispensing device includes a drive unit, a detector and a controller. The drive unit is configured to operate a material dispenser. The detector is configured to detect a velocity of the material sensor. The controller is programmed to maintain the material dispenser at a constant velocity based on the velocity detected by the detector.

A flowable material dispenser including a barrel defining a cylindrical interior volume for holding a flexible material bag containing a flowable material. A nozzle is attached to the first end of the barrel for discharging the flowable material through a nozzle hole; and a closure is disposed on the second end. A center nut disposed on the closure holds a threaded drive rod threadably and rotatably inserted in the center nut. The drive rod includes an inner end and an outer end. Drive structure for imparting rotational forces to the drive rod moves the drive rod reciprocally and axially within the cylindrical interior volume of the barrel to twist and wring out flowable material contained within the flexible material bag.

The invention relates to any field that requires suctioning and/or dispensing fluids of various viscosities (i.e. oil, grease or other like fluids) through a nozzle into a container or mechanical assembly (such as but not limited to robotic RV reducers used in industrial robotic arms, general purpose gearboxes used in various mechanical assemblies such as conveyors and internal combustion engines) for the purposes of transfer of fluids (such as but not limited to lubricating a system, injecting lubricant fluids into light and heavy industrial machines etc). This apparatus can be used in fluid transfer, dispensing and injection applications requiring monitoring of flow pressure and volume.

The present technology is a material dispensing system for controllably dispensing material from a packaging such as a chub pack. The system can include a housing capable of receiving the packaging, at least one nozzle tip including at least one piercing projection capable of piercing the packaging, a piston rod, a motor, and a transmission assembly for converting torque from the motor to a translation output of the piston rod. A ring gear can be operably associated with a planetary gear of the transmission, with a lock block slidingly engageable with the ring gear to prevent it from rotating or to allow the ring gear to rotate freely. A trigger is utilized to control the motor and to operate the lock block.

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. An alternative embodiment includes a lockable, compressible gas spring. Another alternative embodiment includes a rotating element driven by a reversible motor mounted on the handle assembly. The rotating element drives a discharge mechanism in a discharge direction of rotation, and reloads the reservoir in a reload direction of rotation. Multiple alternative embodiments of linear actuators are disclosed. An alternative embodiment includes a push-to-open valve mechanism.

A caulking cannon having a motorized plunger-moving component configured to drive a plunger shaft along an axis that is substantially parallel to a caulking-cannon longitudinal axis; a cartridge-holding barrel component coupled to the motorized plunger-moving component; a handle coupled to the cartridge-holding barrel component; a caulk exit-port component coupled to the cartridge-holding barrel component; wherein the plunger shaft is configured to move in a first direction parallel to a caulking-cannon longitudinal axis and thereby enter into a volume of space within the cartridge-holding barrel component; wherein the cartridge-holding barrel component is configured to hold a caulk cartridge having a fluid-chamber volume of at least three-fourths of a gallon; wherein the motorized plunger-moving component has a hand grip; and wherein the caulk exit-port component is configured to channel caulk fluid flow from the caulk cartridge to an exit orifice.
