A reversible cap configured to be removably secured to a dispensing nozzle of a container containing a substance includes a body with a first end and an opposite second end. The first end and the second end of the cap body are each configured to be removably secured to the dispensing nozzle. At least one aperture is formed in a sidewall of the body and is in fluid communication with the second end. The first end, when secured to the dispensing nozzle, is configured to prevent the substance in the container from being dispensed through the dispensing nozzle. The second end, when secured to the dispensing nozzle, is configured to allow the substance to be dispensed through the dispensing nozzle and through the at least one aperture in the body.

A vessel includes an inner container, an outer container, a connector, a cap, and a lid. The outer container includes a first coupler and an outer chamber. The inner container includes a second coupler and an inner chamber to hold a liquid. The inner container is receivable at least partially within the outer chamber. The connector includes a third coupler that is complementary to the first coupler, and a fourth coupler that is complementary to the second coupler. When both the first coupler is engaged with the third coupler and the second coupler is engaged with the fourth coupler, the outer chamber is entirely enclosed within a liquid-proof barrier.

Methods and systems for handling and dispensing fluid are disclosed herein. In some embodiments, a method includes dispensing fluid into an inner chamber and inserting the inner container into an outer chamber of an outer container. The method can include dispensing a coolant into the outer chamber of the outer container and coupling an outer container coupler of the outer container to a first coupler of a connector such that the connector defines a gap between the inner container and the outer container. The method can include coupling a second coupler of the connector to a lid coupler of a lid, wherein the lid coupler has the same thread pitch as the inward-facing threads of the outer container coupler of the outer container. The method can include cooling the fluid to a chilled storage temperature and dispensing the fluid out of the inner chamber.
