METERED DISPENSING CLOSURE WITH INDEXING FORMATIONS

摘要

A closure for dispensing a metered amount of dry product from a container includes a dispensing cap and a metering drum rotatably mounted on the dispensing cap. The dispensing cap has an upper deck with a dispensing aperture and a skirt engaging the neck of the container. The metering drum has an upper deck, a lower deck, and a metering chamber therebetween. The metering chamber has an entrance aperture in the lower deck and an exit aperture in the upper deck. The metering drum is rotatable relative to the dispensing cap between a filling position, where the metering chamber is aligned with the dispensing aperture and dry product fills the chamber, and a dispensing position where the metering chamber is not aligned with the dispensing aperture and dry product can be dispensed. The dispensing cap and the metering drum include formations to index a position of the metering drum.
