A cartridge-based extrusion dispenser assembly includes a carriage configured to hold a fluid cartridge, and a flexible strip system coupled to a plunger and including a first flexible tape operably associated with a second flexible tape. Within the carriage, the first and second flexible tapes opposingly reinforce each other to establish a substantially rigid shaft member. An actuator assembly is configured to feed the first and second flexible tapes into the carriage to advance the plunger to engage the fluid cartridge and dispense fluid therefrom.

The dispensing device includes a hollow tube having an open upper end and an open lower end, as well as a horizontal bar disposed between the walls of the hollow tube adjacent to the open lower end. A disc is movably positioned within the hollow tube, the disc having a central aperture defined therein. A string or other flexible member has one end secured to the disc. The other end of the string is drawn downward in the tube, looped around the horizontal bar, then drawn upward through the central aperture in the disc and out the open upper end of the tube. A semi-solid medication is loaded in the tube between the disc and the open lower end of the tube. When the string is pulled out of the upper end of the tube, the disc is drawn downward, dispensing the medication.

A powered caulking apparatus includes a power source, a motor, a drive gear, an extension tape, and a top roller guide and bottom roller guide. The tape includes extension tape slots that receive gear teeth of the drive gear such that rotational motion of the drive gear translates into linear motion of the extension tape. The extension tape preferably comprises a radius, and the top roller guide and bottom roller guide preferably conform to the radius of the tape. The top roller guide and bottom roller guide may form an interference for the tape while still allowing linear motion of the tape. The apparatus may extend the tape to cause the tape to exert a force on a caulk tube to extrude caulk, and the tape may thereafter reverse linear motion of the tape to remove the force of the apparatus on the caulk tube.

Various aspects and embodiments are directed to a precision dispenser that is hand held and constructed and arranged to receive and release a variety of glue cartridges. In various embodiments, the adhesive cartridges include precision tips that provide, for example, flat even bead with little or no spill or drip. Other precision tips can be constructed and arranged for use with the precision glue gun. In some examples, the precision tips can be tailored to the specific adhesive contained in the cartridge.

Mixing device and applicator for sealants formed by a main body and a handle (1), wherein the main body comprises a container-carrying sheath (7), a rotating cylinder (14), a gear module (11) that can be coupled to a rotor and a set of mechanisms that eject the sealant material. By actuating a trigger (2), a speed regulator (3) and a rotation selector (4) present in the handle (1) in a first action the cylinder (11) rotates in one sense mixing the material and in a second action it changes the sense of rotation and by actuating a cylinder locking system (19 and 20) present in the main body the device ejects the sealant material.

A glue gun device includes a barrel for receiving a fluid material therein, an outer casing connected with a driving end of the barrel to receive a driving unit, a pressing unit disposed in the barrel and including a pressing member that is movable to expel the fluid material out of a nozzle end, and a transmission chain that is connected to the pressing member to be operable to move the pressing member. The transmission chain is configured to extend from a leading end rearwardly, be deflected downwardly at the driving end, and extend forwardly to terminate at a trailing end to define a chain moving track along an extension path of the transmission chain. A drive transmission unit is disposed at the driving end to transmit a drive from the driving unit to the transmission chain to move the transmission chain along the chain moving track.
