Abstract: 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.

Abstract: 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.

Abstract: A sip lid for a children's drinking vessel includes a spout component having a first end region and a second end region opposite to the first end region. The spout component is shaped and sized to be received within a child's mouth. The first end region comprises one or more openings configured to allow liquid to be extracted through the spout component when the child is applying suction to the spout component. The sip lid also includes a base component extending from the second end region of the spout component and surrounding the spout component. The base component is made from an elastic material configured to allow the base component to stretch over differently sized mouths of drinking vessels to form a liquid-tight seal between the base component and the drinking vessels.
