A quick release closure for bottles which provides access to fluids contained therein. The closure includes a U-shaped spider portion having two opposed pairs of legs, and a disk-shaped plug portion having two opposed pairs of slots for receiving the legs and for fitting within the spider. Each leg includes an inward facing lip at a distal end for engaging a flange around a bottle neck, and an outward seal face for abutting an O-ring encircling the plug. The legs also include, at a proximal end, an inward facing wedge for engaging the slots of the plug whereby the legs may be urged outward as the plug rides up over the wedge. The plug further includes a ring-shaped cavity for sealingly receiving the mouth of a bottle, and a pair of fluid channels, having internal openings formed within the ring-shaped cavity, and external openings formed between the slots of the plug. The plug and spider portions are biased apart by means of a spring, and the plug is retained within the spider by the lips formed into the lower distal portion of the legs.
