  • Patent number: 9375292
    Abstract: A device for dispensing a dental material comprises first compartment and the second compartment formed between interconnected sheet-like layers. The compartments encapsulate a first flowable component and a second flowable component of the dental material. The device has a first seal and a second seal for sealing the first compartment and the second compartment in the device. Each seal is adapted to automatically open in consequence of forcing a component of the dental material toward the seal. The capacity of the first compartment and the second compartment relative to each other is dimensioned such that squeezing out the first component from the first compartment by compressing the first compartment causes the first seal and the second seal to open. The device preferably allows easy and quick activation for use of the stored components.

  • Patent number: 9295530
    Abstract: A device for mixing and dispensing at least two flowable components comprises a housing front face with an outlet for the components and a piston having a piston front face. The piston is arranged such that the piston front face and the housing front face are facing each other. The piston front face and the housing front face are adapted to form a channel for the components between each other. The device is adapted to reduce the channel upon urging the piston front face and the housing front face against each other and thereby to displace the components to flow toward the outlet. The device facilitates mixing and dispensing a multi-component dental material.

  • Publication number: 20150329252
    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.

  • Patent number: 9131991
    Abstract: A dispensing device for a dental material includes a cartridge having an outlet nozzle which forms a passageway for the dental material. The dispensing device further includes a closure which is placeable on the outlet nozzle for sealing the cartridge. The closure includes a pin for extending into the passageway, and is further adapted to seal with an outer surface of the outlet nozzle. The dispensing device is further adapted such that the pin is displaceable from the passageway by dental material dispensed from the cartridge, where the displacement causes the closure to release from the outlet nozzle. The invention may provide for relatively easy operation of the dental dispensing device.
