An electrically powered handheld dispensing device used to dispense viscous materials from a cartridge in a drip-free manner. The dispensing device having a cartridge locking mechanism that affirmatively locks a material cartridge in place, limiting its axial motion in the cartridge holder. The dispensing device having a plunger assembly containing dogs that bite into the inner surface of the material cartridge piston after a plunger makes contact with the material cartridge piston. The dispensing device having a motor control circuit that automatically reverses the drive motor at high speed to reverse the piston inside the material cartridge to a predetermined distance when the user releases the trigger control, which may also suck material back from the cartridge nozzle tip preventing drips. A manually operated gear-release mechanism disengages the plunger assembly from the gear drive transmission, enabling rapid movement of the plunger in either direction for the loading or unloading of full or partially expended material cartridges.

A dental-impression-material electric dispenser includes a main body having a longitudinal mounting portion formed therein. A top-open tray part includes, at the front end thereof, extrusion ports communicate with a mixing tip part communicate with each other. An impression material cartridge, having partitioned a first filling chamber and a second filling chamber, is mounted. The mixing tip part communicates with a pair of extrusion ports formed at the front end of the impression material cartridge, and stirs and discharges a silicone base and a curing agent, each being discharged in a fixed amount through the pair of extrusion ports. An extrusion rod part simultaneously presses a pair of pistons of the impression material cartridge mounted on the tray part through a pair of pressing ends. An electric extrusion part receives starting current from a battery cell and allows the extrusion rod part to advance forward through electrical driving.

A dispenser assembly includes a rod, a plunger and a stopper. The rod has a plunger receiving end with a clip receiving recess. The plunger has a rod receiving structure with a rod engaging clip biased to fit to the clip receiving recess of the rod for movement therewith. The stopper has a plunger receiving space that defines an aperture extending through the plunger receiving space with the rod extending through the aperture. The plunger receiving space is dimensioned such that with the rod receiving structure of the plunger located within the plunger receiving space, movement of the rod engaging clip is restricted by contact with surfaces of the plunger receiving space preventing release of the rod from the plunger.

A dispensing control system includes a dispensing device and a remote device. The dispensing device includes a dispenser configured to dispense material from a cartridge disposed in the dispensing device, a first receiver configured to receive information related to the cartridge, a transmitter configured to transmit the information related to the cartridge, and an electronic controller configured to cause the transmitter of the dispensing device to transmit the information related to the cartridge. The remote device includes an electronic controller, a receiver and a transmitter, the receiver of the remote device is configured to receive the information related to the cartridge, the controller of the remote device is configured to monitor the information related to the cartridge and to cause the transmitter of the remote device to transmit the information related to the cartridge to a remote server.

Apparatus and method for the application of a ribbon of fluid material along one or more garment crease lines by relative movement between one or more cartridges which include a reservoir in which the fluid material is provided, and the garment, the one or more cartridges including a dispensing aperture in connection with the reservoir and through which the fluid material is dispensed. Movement means are provided in the one or more cartridges to encourage the fluid material in the cartridge to move towards the dispensing aperture and a pressurised fluid supply is connected to the one or more cartridges to selectively provide pressurised fluid to the movement means and hand operated user actuable control means are provided to allow the selective provision of the pressurised fluid. The provision of hand operation of the user actuable control means allows the apparatus to be significantly more compact. Preferably the operation of the user actuable control means and the movement of the one or more cartridges with respect to the one or more crease lines to dispense the fluid material can be achieved simultaneously by the same hand of the user.

A cartridge for a one or two-component mixing and dispensing system includes at least one flexible film bag as a cartridge wall, a rigid front part that is in particular integrally formed with the at least one flexible film bag and that is arranged at a front end section of the at least one film bag, the rigid front part including at least one outlet opening. The cartridge for a two-component mixing and dispensing system has a first flexible film bag as a cartridge wall and a second flexible film bag as a cartridge wall, and a structure surrounding the cartridge.

A caulk gun includes a body, a pump supported on the body, a motor supported by the body to drive the pump, a trigger supported on the body. The body is configured to support a sealant container adjacent the outlet. A force generated by the pressurized air in the fluid passage is configured to be transmitted to a portion of the sealant container. The pump is in fluid communication with the inlet and configured to drive pressurized air through the fluid passage. Actuation of the trigger is configured to actuate the motor. The pressure release mechanism is positioned at least partially within the fluid passage. The pressure release mechanism is moveable between a first position in which pressurized air can be vented from the fluid passage and a second position in which the pressure release mechanism inhibits venting of pressurized air from the fluid passage.

A caulking gun includes a push disk, a push rod, an adhesive cartridge compartment, a trigger and a gun body; the trigger is hingedly coupled to the middle part of the gun body; the rear end of the push rod is outside the gun body and provided with a braking device; the front end is in the adhesive cartridge compartment through the gun body and provided with a push disk; a push piece for driving the push rod is mounted in the gun body; the front end of the push piece is provided with a return spring; the trigger is provided with a pin position switching device for adjusting the propulsion ratio by adjusting the contact position of the push piece; adjustment of different propulsion ratios enables the caulking gun to be multifunctional to meet the construction requirements of different adhesives.

A caulking gun, comprising: a cylindrical housing; a nut fixed to a rear wall of said housing; a screw threaded into said nut, said screw having a bit at one end thereof, and a bearing connected to the other end thereof; a caulking tube situated inside said housing between a front wall thereof and said bearing, and a stopper, for preventing said bearing from reaching to said rear wall of said housing and as a result being separated from each other; wherein said bit having a depression, for allowing connecting thereto a snap connector, and wherein said housing comprises flexible straps, for providing compact storage of said caulking gun, and wherein said nut is further welded to a second wall of said housing, for holding said screw steady such that its longitudinal axis coincides with the longitudinal axis of said housing.

A method for dispensing fluid from a fluid dispensing apparatus. The apparatus may include a housing, wherein the housing may include a motor, and wherein the motor may be configured to be operatively connected to a power supply, wherein the motor may be further configured to be operatively connected to one or more drive rods, wherein the one or more drive rods may be configured to engage a fixed lead screw with a triangular nut, and wherein the drive rod may be further configured to engage at least two pistons of a fluid cartridge. The housing may include a controller configured to be operatively connected to the power supply, the controller may be configured to generate a pressure within the fluid cartridge by adjusting, via the motor, the drive rod and piston in a first direction relative to the fluid cartridge to dispense fluid in the fluid cartridge.
