Abstract: A syringe (1) for dispensing a dental substance. The syringe has a container (11) that forms at least a first and a second component chamber (111, 112) and a plunger (12) having a first and a second plunger rod (121, 122). The first and second plunger rod (121, 122) are at least partially arranged in the first and second chambers, respectively, for a movement from a full position to an empty position over a displacement length. The syringe (1) further has an actuator (13) that is guided for a movement relative to the container (11). The movement of the actuator (13) is restricted for a predetermined actuation stroke being defined by a length between a rear position and a front position of the actuator (13). The plunger has a toothing and the teeth of the toothing are spaced at a pitch P. The actuator has at least a first pawl (139a) that meshes into the toothing of the plunger (12). The first pawl (139a) and the teeth of the toothing are configured such that in a movement of the actuator (13) in a direction from the front toward the rear position the pawl overrides the teeth and in a movement in the opposite direction the pawl engages the teeth. The displacement length is greater than the actuation stroke and the actuation stroke is at least twice of the pitch P. The syringe (1) allows for precisely dosed dispensing of multiple different portion of dental material.

Abstract: A container for storing and dispensing a liquid has a generally cup-shaped receptacle formed by a circumferential side wall and a front wall. A piston is slidably accommodated within the receptacle. The receptacle and the piston in combination form a chamber in which the liquid is received. The piston forms a sealing structure bearing on an inner surface of the side wall. The inner surface of the side wall has an arithmetic average surface roughness of between 0.05 μm and 4.5 μm R?a.#191 The container allows for air to penetrate in the chamber while it provides for the liquid to be captured therein.

Abstract: A dispenser comprising a body with an outlet, and a closure for the outlet. The closure and the body are pivotally movable relative to each other between an open position in which the outlet is open and a closed position in which the closure closes the outlet. The closure and the body are adapted for locking engagement with each another in the closed position. The closure has a locking member for locking and unlocking the closure and the body in the closed position. A force applied on the locking member for unlocking urges the closure toward the open position. The dispenser preferably facilitates the application of a material to be dispensed to a desired location.

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.
