Abstract: A liquid storage, isolation and dispensing assembly includes a container, a float and a top. The container includes a sidewall having an inner surface, a lower part, and an upper part. At least a portion of the inner surface of the lower part has a constant cross-sectional shape and size. The upper part includes an inwardly extending ledge with a cutout formed therethrough. The float has a sealing edge generally conforming to the size and shape of the inner surface portion. The sealing edge and the cutout are configured to permit the float to be passed into the lower part of the container with a portion of the sealing edge passing through the cutout. The top is mountable to the upper part and has a lug configured to pass through the cutout in the ledge for mounting the top on the container.

Abstract: A liquid storage, isolation and dispensing assembly includes a container, which defines an axis and has an inner surface, top and float. The top is mountable to the upper end with a sealing element engaging the inner surface at a liquid sealing position. The open upper end is least partially unobstructed when the top is at the liquid pouring position. The float includes a top portion, a bottom portion and a sealing edge sized to create a minimal gap between the sealing edge and the interior surface when floating on the liquid surface with the axis generally vertical. Tilting the container creates a gap between the float and the inner surface permitting the liquid to pass the sealing edge and out of the open upper end.
