Abstract: A folded food carton is formed from a matable, lay flat blank for retaining, transporting and serving hot food such as pizza. The blank includes an arrangement of end panels, side panels and cover panels foldable relative to a bottom panel such that, in the erected carton, the cover panels overlap and are interlocked with the side panels by means of offset locking tabs. The end panels slant upwardly and inwardly from the bottom panel to add rigidity and save material for the carton. The side panels flare upwardly and outwardly from the bottom panel and extend above the cover panels to enhance stackability and prevent shifting of stacked cartons one on top of the other. Several methods of packaging pizza in the folded carton are disclosed.

Abstract: According to one aspect of the invention, a shipping container with an integrated pallet has a narrow width adapted for maximum utilization of the available space in standard sea containers, and openings for the tines of a forklift are spaced so that adjustment of the tines is not necessary in order to fit the narrower container. The container has an open top, opposite end walls, opposite sidewalls, and a bottom wall. The pallet is attached on top of the bottom wall and comprises a pallet deck, with runners secured between the deck and the bottom wall in inwardly spaced relation to the side edges of the container so that the runners are located inside the fork footprint rather than outside the fork footprint. The tine-receiving openings are thus positioned outboard of the runners and under opposite side edges of the container.

Abstract: The present invention provides a container having a carton and a cover sized to fit over and enclose an interior space of the container. Carton and cover each are adapted to permit controlled flow of air in to and out of the interior space of the container. In a preferred embodiment of the present invention, cover sidewalls are adapted to move between an open position and a closed position, wherein air is permitted to flow in to and out of the interior space of the container when the sidewalls are in an open position, but inhibited from flowing in to and out of the container when the sidewalls are in a closed position.

Abstract: A lid is provided for use as a cover on a beverage container or other dispensing device, wherein the lid includes a dispensing spout therein for dispensing of the container contents therefrom. A flexible connector arm extends around at least a portion of the periphery of the lid and includes a fixed end fixedly attached to the lid at a first arcuate position thereof and a free end frangibly connected to the lid by a frangible tab located at a second arcuate position of the lid. The free end of the connector arm can be detached from the lid by tearing along a tear line provided in the connector arm spaced radially outwardly from the frangible tab. In this manner, detaching of connector arm from the lid occurs by a discrete tear line propagated through the connector arm, rather than through the lid flange, thereby allowing for detachment of the connector arm from the lid without compromising the integrity of the seal between the lid and the cup.

Abstract: A method and apparatus for obtaining a desired nip pressure distribution profile in the cross direction of a paper web. The paper web passes through a nip, the latter defined by at least one elastomer covered roll, the covered roll having polarizable particles or magnetic particles embedded therein. A plurality of spaced plates or spaced coils each generate a local field (respectively electric or magnetic) which acts upon individual spaced zones or regions along the covered roll. The field may thus be an electric field or a magnetic filed. The affect of the field is to change the effective modulus of the elastomer by acting on the particles. In turn, this action varies the nip pressure pulse as to exert a desired pressure at each of a plurality of spaced zones or regions on the paper web, to thus create or process a more uniform product in the nip. The method and apparatus can be used, for example, to improve web moisture profiles in the press section of paper machines.
