A dispensing apparatus for the dispensation of a fluid onto a surface, the dispensing apparatus has a nozzle including a main body and a tube holder made of a deformable material installed on the main body. A dispensing tube having a first end from which the fluid is discharged onto the surface and a second end that is immersed in the fluid in use extends through the tube holder, such that the first and second ends are arranged to protrude from opposite ends of the tube holder. The nozzle is configured to be detachably coupled to a syringe-nozzle adaptor having a tubular body by interference fit between the tube holder and the tubular body of the syringe-nozzle adaptor. The syringe-nozzle adaptor is further attachable to a syringe for storing the fluid.

The invention relates to a dental applicator comprising an applicator housing and a plunger body guided movably in said applicator housing, wherein the applicator housing comprises a connection for detachably mounting a cannula in a pressure-resistant manner, said cannula comprising a connection body and a cannula tube that is rigidly connected in or on said connection body, and the applicator housing (12) and/or plunger body (14) having a receiving device (22) for at least partially receiving a bendable cannula tube (20).

A hardenable (e.g. dental) compositions is described comprising an encapsulated material. The encapsulated material comprises a basic core material and an inorganic shell material having certain viscosity criteria. Also described are dispensing devices and kits are described comprising a hardenable (e.g. dental) composition comprising a liquid material and an encapsulated material wherein the encapsulated material comprises a basic core material and an inorganic shell material comprising a metal oxide surrounding the core. The dispensing devices and kits can facilitate the methods of applying the hardenable composition. The hardenable or hardened (e.g. cured) composition can provide various technical effects such as a delayed release of a basic core material, a delayed increase in basicity, promoting remineralization of a tooth or bone structure, and increasing the average alkaline phosphatase (ALP) activity of pulp cells. In some embodiments, the composition is a dental (e.g. sealant) composition to a tooth structure.

An applicator is proposed comprising an outer sleeve having a cylindrical inner surface and a receiving space for a flowable substance to be applied and an inner sleeve which can be displaced in the outer sleeve and in which a frangible ampule containing the flowable substance is disposed and which has an opening connecting an interior of the inner sleeve to the receiving space of the outer sleeve and an activation means upon whose activation the ampule breaks.

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.

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.

The invention relates to devices and methods of a puncturing nozzle head for safe and efficient release of fluid when used in assembly with a caulking device or any other fluid dispensing devices. The puncturing nozzle head is disposed over a barrel of the caulking device as a cap. The puncturing nozzle head is formed of a dispensing tube with a base plate. For example, the dispensing tube may be a conical shaped tube extending from the base plate. A plurality of puncturing rods may be disposed at an inner surface of the base plate. For example, the puncturing rods are configured to puncture a sausage pack containing caulking material which is loaded into the barrel of the caulking device. A nozzle head lock ring is provided to lock the nozzle head in position to the barrel.

A mixing device for bone cement comprising a plunger for extruding the mixed material, which plunger is also used as a cover. The plunger has spring blades adapted to be latched on a collar of the housing.

Medical adhesive applicators are disclosed which allow medical adhesives to have long storage life and be easily dispensed in a controlled manner. In one embodiment, the applicator has a frangible glass vial with the medical adhesive. The frangible glass vial is held in a plastic enclosure with a dispensing tip. Attached to the plastic enclosure is a squeeze tube capable of imparting air pressure into the enclosure. In another embodiment, the applicator has a proximal chamber containing medical adhesive, a distal chamber for dispensing medical adhesive and one or more rupturable membranes between them. In another embodiment, an applicator pad is sized to retain the total volume of adhesive and initiator so that, in use, the entire volume of adhesive liquid is first loaded into the pad. So loaded, the adhesive and initiator mix evenly to provide an adhesive layer that cures puddle-free.
