An application device for materials, in particular adhesives, including at least one cartridge receiving device for receiving a replaceable cartridge which contains a material and has a material outlet opening; a rotary device for metering or mixing the material, rotary device having a first engagement element; a drive device for driving the rotary device, the drive device having a rod which is mounted in a rotatable and axially movable manner and has a second engagement element at the end face; and a gearing unit for driving the rod in order to bring the first and the second engagement element into engagement with each other.

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 discharge device that serves the purpose of discharging at least two components from a multiple cartridge. The discharge device has a housing, a threaded rod and an advancing element with an internal thread. The threaded rod engages in the internal thread of the advancing element such that the advancing element can be pushed forward in a distal direction by turning the threaded rod in relation to the housing. In the region of its distal end, the threaded rod has a taper. Formed on the housing, in the region of its distal end, is a holding element. The holding element has a laterally open clearance, and the threaded rod is pushed with its taper laterally into the clearance of the holding element such that the holding element fixes the threaded rod axially in the housing in the distal direction and in a proximal direction opposite thereto.

A device is provided for assembling components of a mixing syringe for use in a dental procedure. For this assembly, the components of interest include a beak and a mixing tip for the syringe. Specifically, the device includes a top plate formed with a hole, and a support member for the top plate that maintains the hole at a predetermined height H above a surface when the device is placed on the surface. For an assembly operation, the beak is supported on the device with a portion of the beak inserted downwardly through the hole of the top plate. This also extends a gripping member of the beak upwardly above the top plate. A grab ring of the mixing tip is then pushed against the gripping member of the beak for their engagement with each other. They are then removed together from the device and engaged with the mixing syringe.

Caulk tubes having caulk tube plungers with internally threaded apertures are described herein.

A device comprising a housing including a palm portion, a sheath portion extending from one end of the palm portion, and a slot comprising an adjustable platform capable of receiving a syringe and a needle connected to the syringe with the needle resting in the sheath portion. A trigger mechanism is connected to the adjustable platform. Adjustment of the trigger mechanism in a first direction moves the platform along the slot toward the sheath portion and adjustment of the bidirectional trigger mechanism in a second direction moves the platform away from the sheath. A light element is connected to the housing and is capable of directing light along the sheath portion away from the palm portion. A power source is electrically coupled to the light element to provide electrical power to the light element. Also disclosed is a system comprising the device, as well as methods of using the device.

An applicator for on demand incremental dispensing of dental compounds from interchangeable prefilled cartridges. A hand held applicator support body with a threaded drive rod, selectively advanced by a trigger activated indexing lever assembly for advancing engagement within the medication cartridge. A release and positional indicator allows for drive rod engagement and resetting therewithin.

The invention comprises a dispensing device having an elongated body, a sidewall which is elliptical in at least a portion of its cross-section, an open top end, and a dispensing bottom end. The device comprises a ratchet, ratchet support member, dial, telescoping members, and an elliptical plunger. The ratchet support member and dial each engage the ratchet to allow movement in certain directions and prevent movement in other directions, beyond a certain point. A first telescoping member is affixed to the ratchet. The exterior diameter of a second telescoping member is smaller than the interior diameter of the first telescoping member, such that the second telescoping member is configured to nest within the interior of the first telescoping member. The second telescoping member may be extended a distance through the dispenser body via rotation of the ratchet. The plunger is affixed to the telescoping member having the smallest diameter.
