Abstract: In exemplary implementations of this invention, a warmer is configured to hold warm water and a container of chilled or frozen breast milk, and to heat the breast milk by heat transfer from the water to the breast milk. The warmer may comprise a vessel (for holding the warm water), flexible bristles and a lid/dome. The vessel is insulated by a vacuum layer. The water can be poured into a cavity in the vessel. The vessel is penetrated by a hole that opens into the cavity. In exemplary implementations, the flexible bristles protrude into the hole, and are configured (i) to be elastically deformed when a human user inserts or removes a breast milk container through the hole, and (ii) to inhibit bobbing of the container, due to buoyancy.

Abstract: The present invention generally relates to a foldable baking pan which is formed by locking four panels onto a bottom panel. Each of the panels have a grasping portion which mates with a corresponding portion on the underside of the bottom panel. To assemble the pan for use, the grasping portions of the panels and the bottom panel are first mated. The panels are next rotated to an upward position to form the pan. The panels are then locked into place. The assembled pan may then be used for baking or other suitable uses. The pan may be easily disassembled for cleaning and/or storage.
