A container and overcap assembly includes an open mouth container and an overcap with a built-in spout that is hinged to the overcap. The spout snaps shut inside the overcap when in a fully closed position and snaps into a fully open position as well. The spout accommodates a metered dose of product. In the fully open position, the spout seals the opening in the overcap to prevent product from exiting the container while a metered dose is dispensed from the open spout. The container assembly is particularly useful for containing and providing metered dispenses of dry products such as powders and granulated materials.
