A dispensing system (10) configured to dispense a dental composition, the dispensing system including: (i) a dental tray (14) comprising a tray reservoir (18) configured to receive a dental composition (26), and further comprising a guide rail (22); (ii) a dental composition reservoir (12) for containing at least one dental composition; and (iii) a dispensing mechanism (16) in communication with the guide rail and configured to expel the dental composition from the dental composition reservoir in response to the dispensing mechanism moving along the guide rail, the dispensing mechanism comprising a nozzle (24) configured to direct the dispensed dental composition into the tray reservoir.

A connecting chuck of a material cylinder for a mixer and a mixer are disclosed according to the present application. The chuck includes a chuck body, and a first axial position-limiting connector and a second axial position-limiting connector are provided on the chuck body. After the chuck body rotates around the outlet pipe of the material cylinder by a preset angle, the first axial position-limiting connector can cooperate with a first axial position-limiting cooperating member on the material cylinder, and the second axial position-limiting connector can cooperate with a second axial position-limiting cooperating member on the mixer, so that an inlet pipe of the mixer is compressed with the outlet pipe of the material cylinder for cooperation. Through the above structure, after use, the chuck body reversely rotates to an initial position and the mixer is replaced, and the chuck body is reusable without replacement.

The invention relates to a mixer (11) for dispensing a multi-component material comprising: a first inlet (14a, 14b) for at least a first component (A, B) of the multi-component material; a mixing tube (18); a compartment (21a, 21b) for at least a second component (C) of the multi-component material; a duct (25a, 25b) that establishes a fluid communication between the inlet and the compartment, wherein the duct forms a first exit (20a, 20b) into the mixing tube and the compartment forms a second exit (22a, 22b) into the mixing tube.

A dispenser for dispensing a liquid such as a tooth whitening gel can include a plunger and a housing having a first chamber that receives a first arm of the plunger and a second chamber that receives a second arm of the plunger. The housing can further include a first channel in fluid communication with the first chamber, a second channel in fluid communication with the second chamber, and a third channel formed at an intersection of the first and second channels. The housing can further include a static mixer than mixes a first liquid from the first chamber with a second liquid from the second chamber. The plunger may be disposed along a first axis and the third channel may be disposed along a second axis that intersects the first axis at an angle of between 10 and 170.

The present disclosure relates to the field of mixing and dispensing apparatuses. A mixing and dispensing apparatus of the present disclosure facilitates automatic mixing and dispensing of a semi-liquid form of a powder material when mixed with a fluid. The apparatus comprises a mechanism to hold and rotate a cartridge, an actuation device, and an injection unit. The cartridge consists of the powder material to be mixed with the fluid. The mechanism rotates the cartridge about a primary axis of rotation and a secondary axis of rotation to uniformly mix the powder material with the fluid. The actuation device performs a piercing stroke to pierce one end of cartridge, and a dispensing stroke to dispense the semi-liquid form of the powder material through other end of the cartridge. Further, the injection unit is disposed within the actuation device to inject a pre-determined quantity of fluid following piercing stroke.

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.

A dispensing system (10) configured to dispense a dental composition, the dispensing system including : (i) a dental tray (14) comprising a tray reservoir (18) configured to receive a dental composition (26), and further comprising a guide rail (22); (ii) a dental composition reservoir (12) for containing at least one dental composition; and (iii) a dispensing mechanism (16) in communication with the guide rail and configured to expel the dental composition from the dental composition reservoir in response to the dispensing mechanism moving along the guide rail, the dispensing mechanism comprising a nozzle (24) configured to direct the dispensed dental composition into the tray reservoir.

Disclosed is a connection tip for a dental device for universal application, including a hollow cylindrical body including, on the one hand, a fastener for its retention inside the dental device and, on the other hand, a recognition unit which are activated during the connection of the tip inside the device and allow initializing predetermined control unit depending on the profile of the connection tip.
