Abstract: Disclosed is a carton having adjustable air passages and a blank for forming it. The carton is formed of slidable inner and outer tapered sleeves having complementary spaced openings. The openings are positioned to provide open air passages when the inner sleeve is slid to a first position, and to close the passages as the inner sleeve is moved toward a second position. A stop is provided in the outer sleeve to limit movement of the inner sleeve when slid to the first position, while the taper between the sleeves precludes undue movement of the sleeves past the second position. A shiftable tab is also provided on the outer sleeve to block sliding movement of the sleeves relative to each other until the carton is ready for initial use.

Abstract: This invention relates to a moulded container which comprises at least two container portions, each consisting of a bottom wall segment and a side wall, each side wall being integrally moulded with its associated bottom wall segment and retained in an upstanding relationship with respect thereto, the bottom wall segments being interconnected to form a bottom wall of the container, each bottom wall segment being connected with respect to the remainder of said bottom wall in a manner to permit flexing of the bottom wall whereby said moulded container may be moulded with said container portions disposed in a first configuration in which said bottom wall segments are inclined with respect to one another to dispose the side walls in a position facilitating removal from a mould and subsequent nesting of the containers and thereafter said bottom wall segments may be hinged along each hinge line to a container configuration.

Abstract: A cylindrically shaped, open topped carton suitable for containing ice cream or the like includes a polygonal shaped base and a pair of side wall sections formed integral with the base which are joined together along mutual edges to provide an essentially cylindrical exterior surface defining a circular opening in one end of the carton opposite the base. A plurality of Y-shaped pleats are provided in lower portions of the side walls at circumferentially spaced intervals corresponding to the juncture of the edges defining the polygonal base to provide a smooth transition of the side walls from an angular cross-section at the base to a circular cross-section at the open end of the carton. A multi-ply rim provided with specially configured extension flaps for holding the rim in place on the side walls of the carton extends outwardly from the side walls to assure tight frictional engagement with a removable lid while also facilitating lid removal.

Abstract: An integral handle, self-locking, carrying container formed of paperboard.

Abstract: A laminated packing container with a substantially flat bottom surface is disclosed. The packing container has a plurality of side walls and both a top end wall and a bottom end wall. A plurality of upper and lower corner lugs are located at the intersection of the side walls and the end walls. A crease line which angles in toward the center of the bottom end wall is located between each lower corner lug and the bottom end wall such that upon formation of the packing container the crease line results in a portion of the laminate being displaced into the packing container to permit the bottom surface of the packing container to have an improved flatness.

Abstract: A wide-folding, linearly-hinged assembly of sheet members secured to each other in areas other than in the vicinity of the hinge is disclosed comprising: an inner sheet member having at least one ply and a female linear score on the inner side thereof; and an outer sheet member having at least one ply and at least four linear female scores arranged in pairs on opposed sides of said member, each of said outer scores bridging its paired inner score and said opposed pairs bridging said score of said inner sheet member.

Abstract: An improved blank for a scoop-type carton with a layout and method for the cutting of quickly erected scoop-type cartons with a maximum of nested common edges and the remaining edges at a distance exceeding the widths of two cutting knife blades. This is partially obtained by increased use of common edges parallel to the carton center line and the areas on the flaps for gluing.

Abstract: The container of the present invention is constructed from a single blank of cut and scored paperboard to form a pair of hinged sections which meet one another when the container is closed. Each section of the container is self locking and comprises double wall top and bottom panels and integral handles. In addtion, one of the sections includes a locking flap with integral locking ears for frictionally holding the two sections in closed condition.

Abstract: A hinged lid or flip top cigarette pack includes an inwardly stepped or offset collar 29 abutting the top areas of the pack front and side walls. The collar is only joined to the pack by narrow Z-folded residual connections 30, 31 at the opposite ends of the collar front wall 32, the remaining portions being severed by cut lines 36 and 40-42 which define an intermediate reinforcing strip 44. This strip is folded in against the front wall of the pack along a weakened fold line to define a rounded upper pack edge 46, which overlaps with the lower edge of the collar front wall along a narrow zone 47.

Abstract: A tray having tab, bottom, side and end walls arranged and disposed so that by pushing inwardly on the end walls, a tray will be formed from a flat tubular structure and the end walls will snap into interlocking engagement with the top wall.

Abstract: A carton formed of a single blank of cardboard or the like cut and scored to form four wall panels and an attachment flap, each wall panel having foldably attached thereto a flap comprising a plurality of rectangular foldable flap sections. The flaps attached to an opposing pair of wall panels are foldable to form a pair of spaced flap assemblies constituting beams for supporting projecting members of filing binders stored in the carton. Hand openings are formed in that pair of wall panels immediately under the beams. The flaps attached to the other pair of opposed wall panels are foldable so that notches formed therein create shoulders for underlying end portions of the beams.

Abstract: A carton with a pyramid-shaped bottom and a blank for forming same has a collapsible pyramid-forming bottom structure which is hingedly coupled to the bottom edges of the side wall panels of the carton. The bottom structure comprises four triangular bottom panels, each of which is hingedly coupled to the bottom edge of one of the side wall panels and pairs of which are hingedly coupled together. One panel of each of the pairs of bottom panels has a locking tab with an abutment edge for abutting the abutment edge of the other locking tab to retain the carton in an assembled configuration against the bias of the carton towards its collapsed configuration. This permits the carton to be shipped and stored in essentially flat, collapsed configuration and then easily rearranged to its assembled configuration by the application of inwardly directed forces against side edges of the flat, collapsed configuration of the carton.

Abstract: Boxes for produce and the like formed by corrugated paperboard containers having end walls defining vertical slots that are aligned when the containers are stacked. Column-forming members are inserted in the slots and interlocked vertically. The containers are supported primarily by the inserts so that the combined weight of containers above is not borne solely by the end walls.

Abstract: Unitary double cavity cartons, for example, of the type commonly referred to as clam shell cartons, are provided in which lines of weakness, adjacent the center hinge and positioned to form a hinge ridge or channel upon closing, permit the carton to open freely without buckling or tearing.

Abstract: A paperboard tray includes flanges which abut but do not overlap when the tray is erected. The flanges are connected to tray side wall panels along fold lines which are selectively scored to compensate for different stiffness of the paperboard material along and across its grain. The selectively scored fold lines allow the flanges to uniformly bend when subjected to equal bending forces exerted on the flanges. The abutting flanges and the selectively scored flange fold lines make the tray particularly suitable for use in manufacturing processes in which the tray is lined with a non-porous film material.

Abstract: A box of cardboard, paperboard, fiberboard or the like assembled from a single, die cut blank comprising a bottom wall, side walls, front and back walls, and a swingable top closure. The side walls are provided with inturned flanges underlying a flange extending rearwardly from the front wall which latter contains outwardly projecting stops. The top wall carries locking tabs for restrictive abutting relationship with the proximate stop and which tabs embody tongues lockingly engageable in openings in said side wall; there being abutments for limiting lateral shifting of said top wall when the box is closed.

Abstract: A one-piece box blank which is formed of hingedly interconnected top, rear and bottom walls and end panels hingedly connected to the front and rear walls and adapted to interleave and interlock to form end walls of the box, has opposite ends of the bottom wall notched so that the bottom wall is shorter in length than the front and rear walls and is therefore adapted to nest in the top of a substantially identical box. Nesting is also facilitated by notches formed in the lower edges of the end walls and the fact that the upper edges of the end walls extend above the upper surface of the top wall. With this construction several containers can be stacked with the notched ends of the bottom wall received between the upper edges of the end walls, mechanically interlocking the boxes against end to end movement and providing substantial frictional resistance against side to side movement by virtue of the contacting surfaces of the stacked boxes.

Abstract: A folding carton having a bucket-like shape. The bottom of the carton body includes a locking flap which is operable to hold the bottom flat. Around the top of the carton is a plurality of holes. A separate lid includes tabs which are engageable in the holes. The lid further includes an integral handle by which the carton may be carried.

Abstract: The bottle carrier of the present invention is constructed from two half slotted containers that have their manufacturers joint located substantially midway along a side wall and which are connected together along that side wall to provide an integral divider that separates the carrier into two equally sized compartments. The two half slotted containers also include partial hand hole cut outs in each end wall which come together when the containers are connected to form a pair of complete hand hole openings.

Abstract: A wrapping device, formed of a unitary paperboard blank, secured tightly against the sides of a container and against the cap thereon, which is easily torn upon attempted upward movement of the cap for the purpose of, for example, the attempted fraudulent switching of a low price-marked cap to a larger size, higher priced container. The wrapping device is in the form of an elongated strap of paperboard, which has at least one aperture therein through which a part of the container's cap protrudes. A carton for a plurality of capped containers is formed from a plurality of the wrapping devices, which are in turn formed from a unitary blank. An assembly for a plurality of capped containers is formed from a plurality of the wrapping devices releasably coupled together.
