ABSTRACT:
A measuring and dispensing closure for dispensing a measured amount of material from a container. The closure has a wedge rotatably secured between a pair of discs one of which is attached to the container and each having defined therein a dispensing slot which is offset from the other dispensing slot. The wedge has a metering chamber which is alignable with the dispensing slots in the discs for dispensing a metered amount of material from the container, and a sealing surface alignable with the dispensing slot in the disc attached to the container for effecting an essentially air-tight seal of the container. The metering chamber is divided so that less than a full charge of material can be dispensed.
