ABSTRACT:
A package for dispensing premeasured quantities of a granular or powdered fluent material, having an elongate container with sloping shoulders and an open, upstanding neck surmounted by an overcap. The overcap has a topwall, a dispensing orifice, an outer skirt, and an inner skirt separate from or partially contiguous with the outer skirt. The inner skirt surrounds the container neck in an overlapping, laterally-spaced relationship. These define a preliminary measuring section above the container neck bounded by the topwall and the inner skirt, a main measuring section bounded by the sloping shoulders and the outer skirt, and an outlet passage located between the inner and outer skirts and communicating with the dispensing orifice. The lateral separation of the inner skirt and container neck is such as to constrict flow of material from the preliminary measuring section to the main measuring section during inversion of the package and to permit such flow on restoring the package to its normal upright position.
