A measuring and dispensing closure for containers of granular material employs a slide element slidable in and out of a container cap top. The slide element has a chute element positioned thereon defining a series of trap spaces into which granular material is passed from the container when the slide element is in its retracted position. When the container is turned upside down and the slide element is moved outwardly relative to the cap top, the chute chamber passes out from a discharge opening formed on the cap top to expose the trap spaces to atmosphere for dispensing the granular material. Communication between the interior of the container and the trap spaces during dispensing is prevented by a planar ledge portion formed on the cap top and underlying the space beneath the chute chamber member. The slide element is preferably formed of plastic molded material and also includes a biasing member to provide a return force against outward movement of the slide. The series of trap spaces are positioned in sequence so that the user may dispense all or only a portion of the material collected by the chute element, depending upon the amount of outward extension of the slide.
Apparatus for dispensing a predetermined amount of material from a container comprising a cap attachable to said container and having a top portion, said top portion comprising housing wall means, for defining a collection space communicating with the interior of said container and a laterally facing discharge opening leading from said collection space, and a planar ledge portion between an outer edge of said top portion and a bottom edge of said discharge opening, and a slide element comprising a generally planar top wall having an opening formed intermediately thereof and carrying underneath a chute element and a biasing means, said chute element comprising a series of longitudinally spaced lateral wall surfaces defining therebetween a corresponding series of vertically open trap chambers facing said top wall opening therebeneath across a gap, said biasing means comprising a resilient member which is compressed during outward movement of said slide element for providing a return force upon said slide element, said slide element top wall lying on said housing wall means for slidable movement thereover such that said chute element trap chambers pass into and out of said discharge opening and a portion of said housing wall means fits into said gap, whereby said trap chambers are contained in said collection space when said slide element is in its closed position and pass over said ledge portion during outward movement of said slide element.
Apparatus for dispensing a predetermined amount of material from a container comprising a cap attachable to said container and having a top portion, said top portion having a laterally facing discharge opening leading from a collection space defined in said top portion in direct communication with the interior of said container, and a planar ledge portion between an outer edge of said top portion and a bottom edge of said discharge opening, and a slide element reciprocable along said top portion comprising a chute element positioned for passage into and out of said discharge opening, said slide element comprising a planar platform wall carrying said chute element and which is slidably received along an upper surface of said top portion said chute element including a series of longitudinally spaced lateral wall surfaces defining therebetween a corresponding series of trap spaces, such that said trap spaces are contained in said collection space when said slide element is in its closed position and pass over said ledge portion during outward movement of said slide element, said platform wall having an opening formed intermediately thereof directly over said trap spaces.
