Abstract: Among other things, a card blank has a first panel connected along a first fold line to a second panel. The second panel is connected along a second fold line to a third panel. The blank is foldable to form a first configuration in which the first panel, the second panel, and the third panel lie flat against one another. Alternately, the blank is foldable to form a second configuration in which (a) two of the panels can be mated to cause the folding card to form a three-dimensional free-standing card, (b) a bottom of the card has exposed points of contact that lie on a plane to permit the card to rest stably on a surface that is parallel to the plane, and (c) one of the panels is oriented at an angle of between 55 degrees and 85 degrees to the plane.

Abstract: A new jar has (among other features) at least two chambers separated by a fixed partition. Each chamber is at least as broad as it is deep and has opening through which food that is dipped from the chamber can be removed. The two openings of the chambers face as opposite directions. And a lid covers each opening.
