Some embodiments relate to nestable containers having a reversibly deformable covering that is reversibly deformable from a covering position to a storage position, wherein the covering has a projected surface area in the storage position that is less than a projected surface area of the closure in the covering position such that the covering is storable inside the container while other containers of identical size and shape are nested in the container. The covering may include a fastener that, when fastened, prevents movement of the covering from the storage position to the covering position. And the covering and/or container may include a gasket for sealing.
