Abstract:
A food container (10) comprising three or more plies, a first ply (22), a second ply (24), and at least a third ply (26). The first ply (22) is oriented towards the hands and face of the user and receives food in use. The first ply (22) is essentially continuous throughout its plane. The third ply (26) is oriented towards the lap of the user or a table top in use. The second ply (24) spaces the first (22) and third (26) plies apart. In a preferred embodiment, the food container (10) may be made of a corrugated material. The food container may be made from a blank which is deformed out of its plane during manufacture.
Abstract:
A partition matrix (10) is formed by intersecting first (12) and second (14) slotted plastic partitions. Slots (28, 30) of the partitions are engaged with each other at a plurality of intersections (44). The matrix is permanently held together in a nondisassembling relationship without using additional material by at least one parent weld formed by heating an edge (18, 24) of the partitions (12, 14) at one or more intersections (44) until the intersecting partitions are molten and allowing the partitions (12, 14) to cool. A supporting net (56) may be permanently secured to one edge (46) of the partition matrix by either placing the net in contact with heated edges (18, 24) of the partitions (12, 14) while the edges (18, 24) of the partitions (12, 14) are molten or by placing the net (56) and the edge (46) of the matrix proximate a heat source (42) to melt both and then when molten, distancing both from the heat source (42).
Abstract:
This invention relates to a corrugated thermoplastic blank for a container. The blank (20) has a base panel (24) with wall panels (26, 28, 30, 32) connected to the base panel (24) by fold lines (38). The fold lines (38) comprise weld lines which destroy the original memory of the thermoplastic material. The free edges of the blank are sealed by seals (38) which prevent water from entering the blank. The sealed free edges and/or the weld lines or line (38) surround and reinforce each panel (26, 28, 30, 32) and increase the strength of each panel and thereby the strength of a container erected from the blank.
Abstract:
A two-piece container for pizza or the like. The base (12) includes a first pair of opposite side walls (16) having end flaps. A second pair of opposite side walls (18) are each folded to have an outer portion and an inner portion with at least one tab on the terminal edge thereof for engaging a slot in the bottom wall. The end flaps are received between the inner and outer portions. Cut-outs (66) are provided in the second pair of side walls for securely receiving tabs (32) of the lid (22) between the inner and outer portions. A pizza container having raised bottom wall portions for air circulation underneath a pizza is also disclosed. This allows single-face corrugated inserts to be eliminated for cost savings. The container is also disclosed as being composed of corrugated cardboard with fold-line means in the bottom wall and the first pair of side walls midway between the second pair of side walls for folding the base in half for disposal.
Abstract:
A multi-ply food container (10). The multi-ply food container (10) has selective reinforcement (24) at the center of the food container (10), and regions of a raised side wall (16) and/or rim (18) which are not reinforced. The reinforcement is preferably done by joining an additional ply (24) to the food container (10).
Abstract:
This invention relates to a novel method and apparatus for packaging and shipping horticultural products including cut flowers. More particularly, this invention pertains to a novel method of and packaging for packaging cut flowers in a modified atmosphere package to prolong shelf life, shipping the packaged flowers to the destination, and then at the destination, opening the package and rehydrating the cut flowers in the package by saturating the stems of the flowers with water.
Abstract:
A laminated packaging material (12, 12') for fabrication into a container (10, 15) for a flowable food product is disclosed herein. The laminated packaging material (12, 12') has a fluted medium (22) between a first layer (18) and second layer (20). The fluted medium (22) may have a flute density of 200 to 450 flutes per linear foot. The fluted medium (22) may also have a flute height profile of 8 mils to 50 mils. The laminated packaging material (12, 12') may be fabricated into a gable-top carton (10) or a parallelepiped container (15) such as the TETRA BRICK3 container. The laminated packaging material (12, 12') may have a barrier layer (34, 138) such as aluminum or another gas impermeable composition. The laminated packaging material (12, 12') provides substantial material savings due to the fluted medium (22).
Abstract:
A set of blanks, a box, a method and a machine for making a packaging box that includes at least two blanks made of a fibreboard or corrugated fibreboard sheet material, i.e. a first blank comprising a series of at least four flaps for forming the side walls of the box, and a second blank comprising at least two panels joined together along a third fold line. The second blank straddles at least one fold line of the first blank, the first panel is attached to and/or centred on the first blank, and at least one of the second panels is attached to the first blank via means that enable movement of the second panels relative to the first blank when the box is formed by simultaneously wrapping said blanks around a volume having a predetermined size.
Abstract:
A bin formed with a general circular shape in plan being formed from an outside liner of paperboard and an inner paperboard flute providing medium which is affixed to the outside liner. The flutes of the flute providing medium are larger than those of "A" flute. A removable sleeve interior, an optional base and lid providing structures are disclosed together with methods of carriage using same.
Abstract:
An insulating container (50) and a method of manufacturing it comprises providing a sidewall blank (12B) having two sections separated by a fold score (15), and a separate insulating sheet (18) (corrugated, ribbed, embossed, foamed, perforated, etc.) adhesively fastened to one of the sections. Adhesive is applied to an area (12) adjacent the fold score bonding two sections adjacent the folded score. The assembly is wrapped around a mandrel to bring the outer edges together at a side seam (22S) which is sealed to form a sidewall (12). In a second embodiment, the insulating layer can be a coating on one or both of the sections of the two-section starting blank. In a third embodiment, the insulating section (40) can be integral with, and extend from, one edge of the starting blank. It is folded over first to form the middle layer of the wrappable assembly.
