    Abstract: A dispenser for a pasty material has a container, a cover and a handle. The dispenser is operable by twisting the cover and the handle relative to each other in a dispensing direction for dispensing material and, alternatively, in an opposite closing direction. The container having an outlet for the material and the cover having a dispensing opening. The container and the cover are arranged relative to each other for a rotation between a closed position, in which the cover closes the outlet, and an open position, in which the dispensing opening opens the outlet. A first engagement mechanism is provided for enabling the container and the handle to engage with each other in at least one angular position during twisting in the closing direction. The first engagement mechanism further forming a freewheel mechanism with respect to a rotation in the dispensing direction. The first engagement mechanism has a first snap-stop for providing the engagement between the handle and the container and for impeded disengagement when engaged. A second engagement mechanism is provided for enabling the rotation of the container and the cover in an angular range between the closed position and the open position and restricting a rotation outside that range. The second engagement mechanism has a second snap-stop for providing the restriction between the container and the cover with respect to a twisting toward the dispensing direction and providing for an impeded disengagement when engaged in the open position. The first snap-stop provides for an impeding force to be overcome for disengagement and the second snap-stop provides for a snap-in force to be overcome for engagement. The first and second snap-stop are configured such that the impeding force is greater than the snap-in force.

    Abstract: A pen-like dispenser for dispensing a dental material has a handle and a cover which are attached for rotation relative to each other about a longitudinal axis of the dispenser, and a cartridge for holding the dental material and a screw plunger for extruding the dental material from the cartridge by screwing action. The cartridge and the cover in combination form a rotary slide valve which is operable by rotation about the longitudinal axis between a storage position, in which the cover closes a dispensing outlet of the cartridge, and a dispensing position, in which an opening in the cover opens the dispensing outlet of the cartridge. A relative rotation between the screw plunger and the handle about the longitudinal axis is restricted, and a relative rotation between the cartridge and the cover about the longitudinal axis is enabled within a predetermined rotation angle and restricted otherwise.

    Abstract: A device for dispensing a dental material has a cartridge with a dispensing end. The dispensing end has a dispensing opening for the dental material. The dispensing end further has in essence an axially symmetric shape with a truncation. The truncation provides the dispensing end with a generally flat dispensing surface through which the dispensing opening extends. The device has further a cap received on the dispensing end. The cap and the dispensing end are rotatable relative to each other between an open position, in which an orifice in the cap uncovers the dispensing surface, and a closed position, in which a closed space is formed between the cap and the dispensing surface. The device allows for a relatively convenient dispensation of dental material, in particular for a dispensation of a dental composite filling material.

    Abstract: An apparatus for dispensing a viscous dental paste that includes a barrel member, a dispensing tip, and a platform. The barrel defines a chamber for containing a viscous material. The dispensing tip extends from the barrel member to a dispensing end and defines a passageway open to the chamber. The dispensing end forms an outlet opening open to the passageway and circumscribed by a continuous wall defining an interior surface and an exterior surface. The platform projects from the dispensing end and defines opposing first and second major faces. The first major face is aligned with the outlet opening. The second major face is contiguous with a section of the exterior surface. Viscous material is dispensed from the chamber and onto the platform as a ribbon or sheet.

    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.
