  • Patent number: 5386929
    Abstract: Improvements in portion dispensing caps in which pre-measured portions of materials, such as particulate matter, can be dispensed from a container. The portion dispensing caps include a closure and a sliding member. The sliding member is biased in a loading position by a resilient arcuate projection. The sliding member can also include a portion which engages into and seals an opening in the closure. The sliding member may have a hingedly connected wall which is unattached when molded by an injection molding process but which is attached to other walls of the sliding member when the sliding member is disposed in the closure.
