Abstract: A measuring and dispensing device for portable handheld containers is disclosed. The measuring device allows a user to measure and dispense contents from a handheld container with one hand, while using a second hand for managing other tasks. The measuring device comprises, in one embodiment, a body elongated along a lateral axis affixed to a conduit elongated along a longitudinal axis, wherein the conduit is detachably affixed to the opening of a bottle, jar, or similar container holding baby food, milk, granule materials, powders, oil, chemicals, aggregate, or other edible or non-edible contents. The contents are poured through the conduit into a receptacle portion of the body designed to receive only a predetermined volume of the contents, which contents are subsequently dispensed into a target container using only the motion of a user's wrist.
