Abstract: A device for storing and dispensing a flowable dental composition, comprising: a first layer and a second layer, wherein the first layer and second layer form a first chamber for containing a flowable dental composition, a transition zone, and a second chamber; an applicator retained within the second chamber; wherein the first chamber has a first concave surface formed in the first layer and a second concave surface formed in the second layer; wherein the device includes an inactive state and an active state.

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 syringe assembly being assembled from a syringe for dispensing a dental or medical substance, and a protective cover. The protective cover has a geometrically determined, non-foldable tubular protective shaft. The syringe has a cartridge having an outlet for the substance. Further, the cartridge and the protective cover are assembled with the cartridge being received within the protective shaft. The syringe further comprises a dispensing tip that is connected to the outlet for dispensing the substance from the dispensing tip. A first seal is provided between the dispensing tip and the outlet, and a second seal is provided between the dispensing tip and the protective shaft.

Abstract: A syringe for storing and dispensing a first and a second component of a material. The syringe has a first chamber containing the first component and a second chamber containing the second component. The syringe further has an empty blank chamber that spaces the first and second chamber from each other.

Abstract: A dispenser has a bottle (2) and a closure (3) for the bottle (2). The closure (3) has abase (4) forming a dispensing outlet (6) and a flip-cap for openably closing the dispensing outlet (6). The base (4) is attached on the bottle (2). The dispenser (1) further having a hinge (7) which interconnects the flip-cap and the base (4) for swiveling the flip-cap relative to the base (4) between a closed position, in which the flip-cap closes the outlet (6), and an open position in which the outlet (6) is open. The hinge (7) forms a swivel axis. The closure (3) forms a first end (18, 19) in a direction toward the flip-cap and a second end (18, 19) in a direction toward the base (4). The closure (3) in an area between the hinge-level plane and the second end (18, 19) forms an outer surface circumferentially around the longitudinal axis which is at least partly provided by an outer surface of the base (4) and an outer surface of the flip-cap.

Abstract: A method of monolithically forming a flip-top cap from a thermoplastic material and a flip-top cap for dispensing a flowable dental substance. The flip-top cap has a base from which a dropper nose protrudes and a closure. The base and the closure are hingedly connected to each other by a living hinge 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 method has the steps of injection molding the flip-top cap in the open position in an injection molding device and positioning the closure and the base toward the closed position while the flip-top cap is still the injection molding device.

Abstract: A dispensing gun for dispensing a dental material. The dispensing gun has a body with a receptacle for receiving a cartridge therein, a plunger that is displaceable relative to the receptacle, and a lever that is suspended pivotally relative to the body. The plunger has a linear toothing and the lever has an annular gear segment. The linear toothing and the annular gear segment are permanently engaged with each other so that any pivot of the lever in a first direction causes the plunger to displace forward and any pivot of the lever in an opposite second direction causes the plunger to displace backward.

Abstract: A process for taking a dental impression and/or conducting a dental retraction. The process includes the steps of: (a) providing a composition (A) having the consistency (a1), composition (A) including curable components, and a catalyst suitable to initiate or catalyze the curing of the curable components, composition (A) being contained in a device, (b) applying a portion (I) of composition (A) with a consistency (a2) into the sulcus of a tooth, (c) applying a portion (II) of composition (A) with a consistency (a1) in contact with composition (A) applied in step (b), (d) removing portion (I) together with portion (II) of composition (A) from the surface of the tooth, consistency (a2) being higher than consistency (a1).

Abstract: A micro-needle device for delivering a dental local anesthetic that includes a micro-needle array and a hollow spheroid shaped container. The micro-needle array has a base and two or more elongate micro-needles. The elongate micro-needles have an interior surface defining an opening through the elongate micro-needle and the base has a first major surface and a second major surface through which the opening of the elongate micro-needle passes to provide a passage across the base. The hollow spheroid shaped container includes an inside surface, where the first major surface of the base and the inside surface of the hollow spheroid shaped container define a volume that is in fluid connection with each opening of the two or more of the elongate micro-needle. This allows the dental local anesthetic to flow from the volume of the micro-needle device through the opening of the two or more of the elongate micro-needle.

Abstract: A capsule for mixing and dispensing a dental material which has a capsule body and a cavity extending into the capsule body. The cavity is closed by a liquid container. The liquid container has a cartridge forming a channel that extends between a front opening and a rear opening of the cartridge. Further the cartridge has a front foil closing the front opening and a rear foil closing the rear opening. The front foil is attached at the cartridge along a closed path circumferentially around the front opening. The front foil and the cartridge in at least a partial area of the circumferential path are separably sealed with each other, thus defining an openable valve through that path. The capsule has further a piston received in the channel of the cartridge and arranged such that the liquid is enclosed in the cartridge between the front foil and the piston. The capsule facilitates the preparation of a two-component dental material.

Abstract: 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.

The closure (3) has abase (4) forming a dispensing outlet (6) and a flip-cap for openably closing the dispensing outlet (6). The base (4) is attached on the bottle (2). The dispenser (1) further having a hinge (7) which interconnects the flip-cap and the base (4) for swiveling the flip-cap relative to the base (4) between a closed position, in which the flip-cap closes the outlet (6), and an open position in which the outlet (6) is open. The hinge (7) forms a swivel axis. The closure (3) forms a first end (18, 19) in a direction toward the flip-cap and a second end (18, 19) in a direction toward the base (4). The closure (3) in an area between the hinge-level plane and the second end (18, 19) forms an outer surface circumferentially around the longitudinal axis which is at least partly provided by an outer surface of the base (4) and an outer surface of the flip-cap.
