Abstract: A spiral wound can is described in which the body of the can is made up of a relatively heavy fiberboard base or body layer lined within by an oil and moisture impermeable barrier formed from a laminate of aluminum foil and paper. The heavy base layer includes a helically extending separation line or butt joint bonded together by the liner and a reinforcing tensile element in the form of a reinforcing strip. A discrete label covers the reinforcing strip and the body stock and is bonded to the body stock by at least two broken or unbroken lines of adhesive on opposite sides of the reinforcing strip. A circumferentially extending collar cut is made through both the label and the reinforcing strip to facilitate their removal. In one form of the invention, the reinforcing strip is bonded more strongly to the label than to the body and is removed when the label is removed. In another form of the invention, the label is not bonded to the reinforcing strip and is removed first.

Abstract: The novel, knocked-down storage trunk comprising the present invention includes two rigid, molded plastic shells and pairs of side and end walls. In the assembled condition a first pair of lower, inner and outer, concentric clamp rings are used to secure the lower edge of the side and end walls to the lower shell. A second, upper pair of inner and outer concentric clamp rings are secured to the upper edges of the side and end walls. Mating inner and outer vertical corner members are secured to each other and are captured in the upper and lower pairs of concentric clamp rings. The upper shell is hingedly secured to the rear side wall and conventional locks extend between and serve to couple the upper shell and the front side wall. In the knocked-down condition the upper shell nests within the lower shell and the lower shell is seated within the lower concentric pair of clamp rings.

Abstract: A reinforced paperboard produce container having reinforcing end frames of molded thermosetting plastic or other suitably rigid construction secured to the outer sides of the end walls of a paperboard container body with edge flanges on the frames projecting inwardly over the upper end wall edges and under the bottom wall of the body to provide upper and lower stacking edges. The reinforced containers are of sufficient strength, and interfit in such manner, that a number of them may be stacked with ample strength and stability in vertical columns. The lower stacking edges are recessed or bevelled to permit lifting of the container by a clamp truck. The container has hinged lids or cover panels formed with tabs which engage with formations on the end frames to alternatively releasably lock the lids in closed, or open, folded away positions. The containers replace wood containers previously used, and incorporate useful arrangements for latching the lids closed, for shipment, or open, for display of the produce.

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.
