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.

Disclosed is a two-component mixing capsule for intake and for mixing of two compositions with a capsule housing having a discharge spout at its front end, wherein the mixing capsule comprises a first mixing chamber and a second mixing chamber, wherein the two mixing chambers may be separated from each other for storage or for transport, by the first mixing chamber being rotatable into a first position in which the first mixing chamber is separated from mixing chamber, by a rotatably mounted handhold element, the rotational axis of which is approximately perpendicularly arranged to the longitudinal axis of the mixing capsule. The two mixing chambers form a common mixing chamber by rotating the first mixing chamber into a second position in which the central axes of the first and second mixing chamber are substantially coaxially arranged, wherein the composition may be discharged after mixing by attaching a squeezing piston.

The invention relates to a mixing capsule (1) comprising a first chamber (2) to receive a composition A and a second chamber (3) to receive a composition B, characterised in that the first chamber (2) and the second chamber (3) are arranged rotatably about the longitudinal axis (5) of the mixing capsule (1), the first chamber (2) comprising a first opening (25), the second chamber (3) comprising a second opening (26), the first opening (25) and the second opening (26) being arranged perpendicularly to the longitudinal axis (5) and plan-parallelly to each other and/or perpendicularly spaced, the first opening (25) and the second opening (26) being arranged incongruently to each other in a storage position (4), the first opening (25) and the second opening (26) being arranged congruently to each other in a handling position (6). Furthermore, the invention relates to a method for mixing at least two compositions A and B to a composition C in a mixing capsule and to a use of the mixing capsule.

The present disclosure relates to a mixer for mixing pasty components, comprising a mixing case extending along a longitudinal axis and having at least one inlet, preferably two inlets, and an outlet, and comprising at least one mixing element received in the mixing case, which defines a plurality of chambers together with the mixing case, said chambers being arranged successively and/or adjacently along a flow path from the inlets to the outlet. The chambers are defined by transverse walls, each extending perpendicularly to the longitudinal axis, and four side walls that each extend parallel to the longitudinal axis, and adjacent chambers are interconnected by a flow by means of through-openings provided in the side walls, the mixing element comprising two strips forming side walls, which are connected by a web that forms other side walls and is perpendicularly arranged in relation to the strips, a first group of chambers having first through-openings arranged in the web, which extend up to a strip, and a second group of chambers comprising second through-openings positioned at a distance to at least one strip in the web.

A water purification apparatus includes a water inlet; a medicine mixing device in fluid communication with the water inlet; and a water outlet interconnected to the medicine mixing device and a dental treatment center. The medicine mixing device includes a medicine storage for storing antiseptic solution, a mixing unit interconnected to the water inlet, the water outlet, and the medicine storage, and a controller interconnected to the water inlet and the medicine storage. The controller includes a sensor and a microprocessor. The controller sends the antiseptic solution from the medicine storage to the mixing unit and controls a volume of water flowing from the water inlet to the mixing unit. The microprocessor instructs the controller to control a volume of the antiseptic solution supplied from the medicine storage to the mixing unit based on a signal sensed by the sensor.

The invention relates to a capsule (3) for producing a composition, particularly for dental care, comprising an enclosure (6) provided with at least two compartments (8), the number of compartments corresponding to the number of components to be mixed, and at least one wall (10) for isolating the components, said wall (10) being provided to isolate the components form each other in storage mode, and to allow fluidic communication between the compartments (8) in mixing mode, said capsule also comprising a driving rod (2), one end of which is designed in compliance with the ISO 1797 standard, for removable attachment to a hand-held part (1).

A mixing and dispensing apparatus to facilitate 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 the cartridge, and a dispensing stroke to dispense the semi-liquid form of the powder material through an opposing end of the cartridge. Further, the injection unit is disposed within the actuation device to inject a pre-determined quantity of fluid into the cartridge following piercing stroke.

A dental irrigation device for heating a solution and mixing solutes within the solution. The present invention utilizes an oscillator and inductive coil to heat and/or mix the solution. A pump then delivers the heated and mixed pressurized solution from a basin ultimately into a dispenser.

A mixing segment for a static mixer includes inlets and outlets connected by a passage to deflect respective part flows of a material from the inlet to the outlet. Each of the outlets arranged such that an extent thereof is rotated by an angle of rotation of at least 45. A first extent of the passages gradually reduces between an inlet and a constriction of the passage, and a second extent of the passage gradually increases between the constriction and the outlet. The reduction in size of the first extent or the increase in size of the second extent is formed by two walls of the passage that are inclined with respect to one another and with respect to the longitudinal axis of the mixing segment, with at least a part of the walls inclined with respect to the longitudinal axis formed by a curved part surface.

The present invention relates to a static mixer for mixing together at least two components. The static mixer comprises a mixer housing; a mixing element having an upstream end with at least two entry openings and a downstream end, the mixing element being arranged at least partly within the mixer housing; a mixing head having at least two inlets provided at an input side and at least two outlets provided at an output surface, wherein each of the at least two inlets is in fluid communication with one of the at least two outlets; and a separating wall disposed between the output surface and the upstream end of the mixing element for separating the components leaving the outlets. The separating wall comprises a free downstream edge which is disposed with respect to at least one of the entry openings so as to allow at least partial flows of the components separated by the separating wall to combine after exceeding the downstream edge and to jointly enter said at least one of the entry openings.
