Abstract
A multi-chambered container for mixing and dispensing having at least two chambers separated by a passageway and including an exterior opening with a non-removable closure. The closure having an integral nozzle and adapted for attachment to the open end of a tubular member with a closed stopper end adapted for forming a plug seal of the passageway between the chambers. The tubular member has openings in its sidewall to allow sampling of the ingredient of the upper chamber in the closed position and dispensing of the commingled ingredients in the open position through the integral nozzle of the closure.
Claims13
A container for holding separated ingredients to be commingled, and for commingling and dispensing said ingredients, comprising:
- (a) at least two chambers having a cross-sectional area circumscribed by a side wall of said container, each chamber adapted to hold one of said ingredients to be commingled, the first of said chambers having an exterior opening;
- (b) a passageway connecting said chambers with an axis centrally disposed in said passageway and extending through said first chamber of said exterior opening, said passageway having a side wall circumscribing a cross-sectional area, perpendicular to said axis, smaller than the cross-sectional area, perpendicular to said axis, circumscribed by said side wall of said first chamber;
- (c) a tubular member located substantially within said first chamber, the first end of which is open to said exterior opening and the second end of which includes a stopper which, in a closed position, seals said passageway by contact of a sealing surface at said second end with said side wall of said passageway, said member further including a second opening from the interior of said tubular member to said first chamber, said opening comprising at least one elongated slot in said tubular member extending substantially from said first end to said second end, said slot being adapted to function both as an air vent and as a fluid flow path;
- (d) a cap attached to said first end of said tubular member, said cap adapted to move with said tubular member between a closed position in which the second end of said tubular member is sealed in and blocks said passageway, and an open position, wherein said second end of said tubular member is not in said passageway, the top of said cap having a means for dispensing ingredients from said first end of said tubular member, through said cap, to the exterior of said container.
