Abstract
A dispenser including a dispenser assembly having a dosing cup mounted within the open mouth of a container with a dispensing spout mounted thereabove and, through a flexible membrane, selectively positioned within the cup to receive a measured dose therefrom, and outwardly removed from the cup to receive a free flow of material therethrough from the container.
Claims16
A dispenser for selective continuous pour and single dose dispensing of granular material, said dispenser comprising a container, said container defining an internal storage chamber, a dispensing spout having one inner inlet end inwardly directed toward said chamber, and an outer outlet end exterior of said container, a dose cup mounted within said chamber and having a discharge mouth aligned with and opening toward said spout, means for mounting said spout on said container for selective movement between a first continuous pour position and a second dose position, said inlet end of said spout, in said first position of said spout, being in outwardly spaced relation to said dose cup discharge mouth with a continuous flow path for granular material formed exterior of said cup from said chamber to said inlet end, said inlet end of said spout, in said second position of said spout, being in said cup inward of said mouth thereof forming a flow path for granular material to said inlet end solely from said cup, and precluding flow of granular material from said chamber to said inlet end.
A dispensing assembly for a container having a rim-defining open mouth therein, said dispensing assembly including an upwardly opening dose cup with an openwork structure extending upwardly and outwardly therefrom peripherally thereabout and defining multiple openings for the passage of flowable material, said openwork structure terminating in an upper peripheral lip adapted to overlie said container rim, and a spout cap overlying said dose cup and openwork structure, said spout cap including an elongate spout generally axially aligned with said cup in spaced relation thereto, a flexible membrane engaged with said spout peripherally thereabout and extending generally radially therefrom to overlie said openwork structure lip, said membrane being flexible to longitudinally move said spout relatively toward and away from said cup, said spout having an inner intake end which, in a first move position of said membrane, is received within said cup, and in a second move position of said membrane, is positioned above said cup and in general alignment with said openwork structure, said membrane being configured to releasably lock in both of said positions.
