    Abstract: A syringe for dispensing a flowable material. The syringe has a cartridge with a cartridge front end and at least a first dispensing nozzle arranged at the cartridge front end. The syringe further has closure for openably closing the first dispensing nozzle. The closure includes a cap and at least a first seal. The cap is telescopically placeable on the cartridge front end. The closure or the cartridge has a first magnet for establishing a magnetic attraction between the closure and the cartridge. In a situation in which the closure is placed on the cartridge front end, the closure and the cartridge can be positioned in a sealing position in which the first seal spaces the cap and the cartridge front end away from each other against a magnetic attraction that urges the cap and the cartridge toward each other.

    Abstract: A method of layerwise building up an object from at least a first and a second light hardenable resin on a 3D printing device, and a 3D printing device that is configured to perform such a method. The 3D printing device has a build platform on which the object can be built up, a light-transmissive carrier comprising a plurality of recesses and a light projector for projecting a light-pattern through the carrier. The method has the steps of (a) partially building up the object and thereby providing an object-in-process; (b) coating a first surface area of the carrier with a first blank layer of the first light hardenable resin; (c) moving the carrier and thereby positioning the first blank layer between the build platform and the light projector; (d) bringing the object-in-process into contact with the first blank layer; (e) irradiating the first blank layer with a light pattern and thereby supplementing the object-in-process by a hardened layer; and (f) separating the supplemented object-in-process from the carrier.

    Abstract: A flip-top cap (83) for dispensing a flowable dental substance which is monolithically formed of a thermoplastic material. The flip-top cap has a base (4) from which a dropper nose (8) protrudes and a closure that is hingedly connected to the base for pivoting between a closed position, in which the closure closes the dropper nose, and an open position, in which the dropper nose is uncovered from the closure. The closure has an end wall (20) forming an outward planar end face (21) and, opposite thereof, an inner face (22) that has a sealing bulge (23). The end wall forms a first thickness (T1) between the vertex of the sealing bulge and the end face and a second thickness (T2) between a marginal area adjacent the sealing bulge and the end face. The ratio between the first and second thickness is between 1.4 and 1.6.

    Abstract: A plunger assembly for a cartridge for dispensing dental material. The plunger assembly has a receptacle, an activator, and a passageway extending through the receptacle along a longitudinal axis. The passageway forms a chamber for storing at least a component of the dental material and has an outlet for the chamber. The activator has a piston for extruding the component from the chamber and a plug for the outlet. The activator is movable to unplug the outlet and to subsequently extrude the component in a single stroke. The plunger assembly helps for reliably emptying the chamber and helps facilitating dispensation of dental materials.

    Abstract: Provided is a capsule for storing and dispensing dental material. The capsule comprises a cartridge for the dental material, and a nozzle. The nozzle being pivotable with respect to the cartridge between a first position in which the capsule is closed for storage and a second position in which the capsule is opened for dispensing the dental material. One of the nozzle and the cartridge comprises a bearing member and the other one of the nozzle and the cartridge comprises a bearing shell, wherein the bearing member and bearing shell form a pivot. Upon pivoting the nozzle from the first to the second position, the seal between the bearing member and the bearing shell is improved.
