  • Patent number: 3941301
    Abstract: A stackable packaging container having an open top and a body portion tapering inwardly from the top to the bottom has a rim formed by an outwardly extending peripheral flange and a downwardly dependent flange depending from the outward flange to be spaced from the body portion. De-nesting recesses are formed in the downwardly dependent flange of the rim to prevent the containers jamming inside one another when stacked, the recesses not interrupting the smooth inner wall of the body portion.

  • Patent number: 3933295
    Abstract: A packaging device forming an insulative structure for hot food sandwiches. The packaging device includes a pair of identical members, which when interconnected, form an insulative food container. Each of the members comprise a dish-shaped portion whose periphery has a planar flange. The inner surface of the dish-shaped portion is stipled to define a plurality of protuberances interconnected by a plurality of valleys. Moisture from the food or sandwich is allowed to accumulate in the valleys, thus preventing the food and sandwiches from becoming soggy. Channels can also be formed on the planar surface for enabling moisture to escape from the packaging device. A bayonet locking arrangement for the members comprises studs formed on the planar surfaces of the members, each of the studs interacting with locking slots formed opposite the studs on the opposite planar surface of the other member. The diameter of the studs is slightly greater than the width of the slots providing a tight friction fit therebetween.
