Multiple chamber dispensing container and closure system

A package for dispensing at least two substances simultaneously in an adjacent relationship, said package comprising:

• a container;
• divider means for internally dividing the interior volume of said container into a plurality of separated storage compartments;
• said container having an outlet end with a peripheral annular outlet wall defining wall defining a discharge aperture communicating with said compartments, said outlet wall having a cylindrical exterior peripheral sealing surface, and said outlet wall having interior peripheral sealing surfaces;
• said divide means including at least one divider wall projecting within said discharge aperture, each said divider wall extending to said peripheral annular outlet wall to define, in cooperation with said outlet wall interior peripheral sealing surfaces, a plurality of discharge passages each communicating with a respective one of said compartments, each said divider wall having generally oppositely facing sealing surfaces that each define a portion of the inner periphery of a respective one of said discharge passages, the cooperative arrangement of each said divider wall and said outlet wall providing each said discharge passage with (1) one of said interior peripheral sealing surfaces in the form of a partially cylindrical surface and (2) at least one planar sealing surface defined by said divide wall whereby said discharge passage has a transverse cross-sectional flow area in the form of a sector of a circle;
• and
• a cover for securement to said container over said outlet end, said cover including (1) a downwardly projecting peripheral seal member having an interior cylindrical sealing surface for sealing against said exterior peripheral sealing surface of said container outlet wall, and (2) a plurality of downwardly projecting interior seal members, each said interior seal member including a planar seal wall and a partially cylindrical seal wall which together have a perimeter with a transverse cross-sectional shape in the form of a sector of a circle generally congruent to the flow area of the sector of one of said discharge passages, said interior seal members being arranged with the partially cylindrical seal walls located on the locus of a circle and with each said planar wall of one of said seal members being parallel to, but spaced from, a planar wall of another of said seal members whereby, when said cover is secured to said container over said outlet end, said seal members project into a respective one of said discharge passages to seal against the sealing surfaces of the outlet wall and each divider wall that define the inner periphery of said respective one discharge passage.
