This concerns sealable containers for household use that combine a container for food, beverages and the like with a lid for closing the container in a tightly sealed manner. The container bottom on the outside has a downwardly projecting flange within which is an open outside volume, while the lid top on the outside has an upwardly projecting raised panel with a sidewall. The raised panel of the lid snappingly and realeasably fits into the outside volume at the bottom of the container, by virtue of which the lid snaps onto the container bottom, creating a stackable situation. Also, the lid can contain on its inside a temperature-maintenance block such as a freezer pack that affects temperature within the container.

The combination of claim 2, wherein the engagement member is an undercut within the lower surface of the lid, which undercut removably engages an edge of the temperature-maintenance block. 6. The combination of claim 5, wherein the temperature-maintenance block has a tapered edge whereby the block is wider at its lid side than at its food side such that the wider portion of the tapered edge fits within the undercut of the lid to removably hold the block to the lower inner surface of the lid. 7. The combination of claim 2, wherein the temperature-maintenance block has a hole therethrough that is sized and shaped to accommodate human digit action by which the block is removed from the lid. 8. The combination of claim 1, wherein the outwardly protruding flange of the container is continuous and extends around the open outside volume of the container to provide an inside peripheral wall on the outside bottom of the container, which inside peripheral wall defines the bounds of the open outside volume. 9. The combination of claim 1, wherein the sidewall of the raised panel of the lid is continuous and extends the periphery of the raised panel. 10. The combination of claim 8, wherein the sidewall of the raised panel of the lid is continuous and extends the periphery of the raised panel to define an outer peripheral wall of the lid panel, and the outer peripheral wall of the lid panel fits within the inside peripheral wall of the outside bottom of the container and in close proximity such that the interference member engages an opposing location on the container outwardly protruding flange or sidewall of the lid raised panel. 11. The combination of claim 1, wherein the interference member is an inwardly directed interference protrusion from the flange of the container bottom, the inwardly directed interference protrusion engaging the sidewall of the raised panel of the lid. 12. The combination of claim 1, wherein the interference member is an outwardly directed interference protrusion from the sidewall of the raised panel of the lid, the outwardly directed interference protrusion engaging the flange of the container bottom. 13. The combination of claim 1, including more than one said interference member as a pair of inter-engaging interference members, one interference member of the pair being an inwardly directed interference protrusion from the flange of the container bottom that engages another interference member of the pair being an outwardly directed interference protrusion from the sidewall of the raised panel of the lid, one of the respective interference projections rides over and rests below the other interference projection for said snapping or clicking engagement and longitudinal releasable securement. 14. The combination of claim 13, including more than one said pair of inter-engaging interference members along the outwardly protruding flange of the container and along the sidewall member of the lid. 15. The combination of claim 13, wherein each interference protrusion of the pair of inter-engaging interference members has a gradually curved profile along two axes or planes that are generally perpendicular to each other. 16. The combination of claim 1, wherein the sidewall, bottom wall or both of the open-mouthed container is insulated against thermal transmission therethrough. 17. The combination of claim 1, further including an insert tray of the container, the insert tray sized and shaped to enter the container through its open mouth, the tray having a floor and providing an interior volume separate from the inside volume of the container, the container sidewall having a stop at a location that engages the insert tray whereby the insert tray is positioned at a desired height along the container sidewall. 18. The combination of claim 17, further including a temperature-maintenance block and an engagement member of the insert tray floor, which engagement member removably supports the block from the bottom of the insert tray. 19. The combination of claim 2, further including an insert tray adapted, sized and shaped to enter the container through its open mouth and be suspended above the bottom wall of the container, the tray having a floor and providing an interior volume separate from the inside volume of the container, further including an additional temperature-maintenance block and an additional engagement member, the additional engagement member being of the insert tray floor, which engagement member removably supports the additional block from the insert tray, whereby two separate temperature-maintenance blocks are supported within the inside volume of the container, one from the lid and the other from the insert tray. 20.
