Adjustable dispensing closure

Claim 1

A two piece adjustable orifice dispensing closure comprising: a closure body adapted for attachment to a container and having a generally cylindrical skirt and a top wall containing an opening of a predetermined size radially offset a predetermined distance from the axis of the body, an annular sealing surface surrounding said opening and raised above said top wall, an annular bead on said closure body located radially inward from said cylindrical skirt; and a lid member rotatably connected to said body by a complementary bead engageable with said annular bead on said body, holding said body and lid member in an axially fixed relationship permitting relative rotation between said body and said lid, said lid member having an annular skirt coextensive with the cylindrical skirt of said closure body, and said annular skirt being radially spaced from said annular bead of said closure body, said lid member further having a top containing a plurality of apertures with their axes radially offset relative to the axis of said lid member a distance equal to said predetermined distance, said plurality of apertures progressively diminishing in size from a size substantially equal to the opening in said top wall to a predetermined minimum size, raised annular sealing seats surrounding each of said apertures, each seat being complementary to said sealing surface independent of said aperture size whereby rotation of said lid member relative to said body permits alignment of a selected one of said apertures with the opening in said body and one of said sealing seats will engage said sealing surface to resiliently resist rotation of said lid member relative to said closure body.
