Patent attributes
A single use unit dosage dispensing closure includes a shell attached to a container, an axial movable cap attached to the shell, a dust cover preventing premature actuation of the cap, and a sealing member coupled to the cap. The shell has an inner guide in communication with the container and the cap is moveable along the guide. The cap has a chamber adapted to dispense material into the container. The chamber is sealed with the sealing member extending across a lower open end thereof, wherein axial movement of the cap along the inner guide member will open the chamber and dispense the contents of the chamber into the container. The axial movable cap is formed from a material with a higher oxygen and moisture barrier property than the material forming the shell.
