Abstract: The present invention relates to a one-piece blank (14) made of corrugated cardboard for the production of a display case (1), the case, the method and the machine for producing said case. The blank comprises a band (2) of panels (15, 16, 17, 18) connected together in pairs by parallel fold lines (24, 25, 26, 27). The band (2) comprises a precut transverse line (20) making it possible to divide the blank into two half-blanks (21, 22), said transverse line determining on either side and for each parallel fold line (24, 25, 26, 27) two separate portions of fold line (24?, 24?; 25?, 25?; 26?, 26?; 27?, 27?) offset relative to one another in order to make it possible to at least partly compensate for the thicknesses of cardboard when the second half-blank is wrapped over the first half-blank around a mandrel.

Abstract: A self-telescoping storage enclosure comprises a first tray that includes a bottom wall, and a major wall, a minor wall, a right wall, a left wall extending up from the bottom wall. The major wall and the minor wall each having an outer surface. The left wall and the right wall each have a notch. The outer surface of the major wall defines a first major outer width, and the outer surface of the minor wall defines a first minor outer width, the first major outer width being greater than the first minor outer width. The first tray can nest with a second tray substantially similar to the first tray that is inverted and oriented 180° relative to the first tray by the inter-engagement of their respective notches.

Abstract: The present invention is directed to a cold seal package that includes constructions wherein two substrates, or two portions of one substrate, are sealingly engaged to one another using a substantially natural latex rubber-free contact adhesive. The two substrates can be easily peeled apart without substantial damage to the substrates. Furthermore, the substrates cannot typically be resealed, or refastened, once peeled apart. That is, the cold seal formed by the adhesive between the substrates is substantially non-refastenable. Advantageously, a cold seal package of the present invention is particularly well suited for aseptic delivery of packaged goods, such as bandages, dressings, and the like.

Abstract: A container body formed from two substantially identical interlocking container members with each of the container members comprising a substantially planer base portion and a plurality of opposing sidewalls connected to the base portion and tab portions extending from at least one pair of the opposing sidewalls with each of the tab portions including an opening and an adjacent interference element is set forth. The interference elements of a first of the two container members is received in respective openings of a second of the two container members for securing the second container member in an inverted condition with respect to the first container member.

Abstract: A container formed of two identical trays. Each tray carries two flanges, the flanges extending from opposite side walls of a tray. One surface of each flange is provided with a layer or coating of a cohesive material. Such a material adheres only to other cohesive surfaces. Storage of the coated blanks, and of the erected trays, is hence facilitated. The container is particularly useful for the packaging of fast food items.

Abstract: An apparatus for the packaging of articles, particularly fragile or other articles which must be hand packed. The apparatus includes an first cover member and a second cover member, each of the first and second cover members being formed from identical blanks which are erected and affixed in a partially raised state. Upon filing of one of the cover members with the articles to be packaged, a remaining side of that member is raised and the other cover member is warped onto the filled member, such that sidewalls of the filled cover member are distorted inwardly, while side corresponding sidewalls of the other cover member are distorted outwardly. A remaining unarticulated wall of sidewall of the other cover member is then folded down into place and affixed.

Abstract: A convertible food container including two outwardly opening shells having inner walls interconnected along a common upper edge thereof for hinged movement of the shells between an open tray-forming position and a closed carton-forming position. The inner walls include integral tongue and recess lock components which are manually engageable to prevent movement of the inner walls, and hence the shells, relative to each other. A separate retainer enables a locking together of two overlying and facing containers in the open positions thereof.

Abstract: A disposable package for fast food has two bowl-shaped sections which are interconnected along the common edge of a pair of adjacent end walls. The opposite end walls have tabs defining male and female connectors whereby the sections can be joined when folded together. Also, the side walls of at least one of the sections is provided with fold-in tabs which can be used to grip an item of food contained within the package.

Abstract: A biodegradable container baked from a waffle material is composed of a pair of half shells each of which has a pair of lugs for flaps engaging in recesses of the other half shell and formed with ribs along generatrices of the respective side wall having detent recesses engageable by bulges or beads of the recesses of the other half shell. Additional ribs can be provided for stiffening purposes. The container is useful for foods distributed at fast-food restaurants or the like.

Abstract: In a carton comprising a tray and a removable cover, peripheral walls on the cover and tray overlapping and engaging each other. Outwardly projecting locking lugs on the cover and tray walls cross each other and interlock upon a movement of the cover to a closed position over the tray and provide spaced points of interlock about the periphery of the carton.

Abstract: A tray formed from a unitary paperboard blank. The tray has a locking tab at each corner, each latching tab projecting beyond the next adjacent tray wall. Two such trays may be latched together to form a closed container. The tray structure is such that two of the trays may be latched together in only one of four possible angular relations of the trays. The tray is rectangular and may be square or oblong.

Abstract: A container having a first piece and a complementary second piece closable over the first is disclosed. Each container piece has a bottom wall and sidewalls having central portions which are connected to the bottom wall. Each of a first pair of opposite sidewalls of each piece has an upstanding tab portion extending from the top edge of its central portion. Each of a second pair of opposite sidewalls for each piece includes two spaced-apart upstanding portions for receiving an associated tab portion therebetween to interlock the container pieces. The opposing upstanding portions for each side wall each have a boss portion for engaging a side of the tab portion of a complementary piece.

Abstract: A food package particularly adapted for packaging food products for eat-in or carryout service is prepared from a pair of combination tray/cover components made from identical blanks of paperboard or the like. Each tray/cover component comprises a base panel with opposed side walls and a rear wall which are retained in an upright condition by glue flaps attached to the rear wall and adhered to the side walls. The front wall remains in the same general plane of the base panel to form an open ended tray for eat-in use. For carryout use, two components are joined together wherein tabs on the ends of the front wall of one component are engaged in slots provided in the rear walls of another component to form a tray/cover combination.

Abstract: A container suitable for packaging food items such as hamburgers or fried chicken is disclosed. The container includes two complementary container pieces, namely a tray and a cover closable over the tray. Each piece has opposing sidewalls provided with tip portions which project longitudinally outwardly over the central portion of each adjacent sidewall without such tip portions to pass through a plane determined by the central portion of each such adjacent sidewalls. The tip portions of each complementary piece interlock to securely close the container.
