A system includes a warming base including a body having a top surface, a recess formed in the top surface, and an induction coil positioned within the body below the recess; a fluid container having an opening; and a lid including a lid body and a conductive heat plate positioned within the lid body, wherein the lid is configured to be removably attached to the opening to close the fluid container, wherein the lid body has a size and shape that are complementary to the recess of the warming base, so as to allow lid to mate with the recess to position the conductive heat plate a suitable distance from the induction coil such that, when a current is applied to the induction coil, a magnetic field generated by the induction coil causes the conductive heat plate to heat, thereby heating contents of the fluid container.

A bottle assembly includes a container, a collar assembly, and a vent insert. The collar assembly includes a collar and a nipple. The vent insert is configured for selective placement on an open top of the container. The vent insert, when placed on the open top of the container, defines a gap for allowing liquid in the liquid chamber of the container to flow towards the nipple and a vent passage having at least one vent opening in flow communication with the liquid chamber for allowing air to flow into the liquid chamber. The vent insert further defines an annular gap forming a portion of the vent passage. The bottle assembly is selectively operable in two different configurations, a first configuration in which the vent insert is placed on the open top of the container and a second configuration in which the vent insert is omitted.

A dispensable food container has a container body having an interior for receipt of dispensable food, and a container lid. The container body has a base and an opening opposite the base, and side walls that are collapsible. The lid has a closed condition in which it closes and seals the opening of the container body and an open condition in which the opening of the container body is exposed for access into the interior. The lid has a dispensing opening which is in communication with the interior of the container body when the lid is in the closed condition. In use, when the lid is in the closed condition, the container body is collapsible by pressure applied to the lid and the base in opposite directions to cause the side walls to collapse and to force dispensable food within the interior of the container body through the dispensing opening.

A system includes a warming base including a body having a top surface, a recess formed in the top surface, and an induction coil positioned within the body below the recess; a fluid container having an opening; and a lid including a lid body and a conductive heat plate positioned within the lid body, wherein the lid is configured to be removably attached to the opening to close the fluid container, wherein the lid body has a size and shape that are complementary to the recess of the warming base, so as to allow lid to mate with the recess to position the conductive heat plate a suitable distance from the induction coil such that, when a current is applied to the induction coil, a magnetic field generated by the induction coil causes the conductive heat plate to heat, thereby heating contents of the fluid container.

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.
