A divider panel is disposed within the tubular structure between the top and bottom panels. A pair of glue flaps are foldably connected to the divider panel side edges, each of the glue flaps being secured to an inner surface of one of the side panels to retain the divider panel within the tubular structure. At least one divider end flap is foldably connected to one of the divider panel end edges. A first aperture is defined through one divider end flap. A second aperture is defined through one of the end closure flaps at one of the tubular ends of the carton to coincide with the first aperture when the carton is collapsed.

Abstract: Adhesive, preferably pressure sensitive adhesive, is applied to an article f manufacture, such as the closure flap of an envelope or paper bag in such a way that the adhesive is protected against activation prior to closing the article. For this purpose, the adhesive is first applied to a continuous web or tape of a carrier material that either has an inherent anti-stick characteristic or is provided with an anti-stick surface coating relative to the adhesive to be applied. Preferably, the adhesive does not cover the entire surface of the carrier strip, but rather covers only areas in the form of stripes extending at least partly across the width of the carrier web. The adhesive stripes are spaced from one another and preferably also from at least one edge of the carrier web or tape. The carrier web is then severed into strips, each provided with one adhesive stripe and these strips with the adhesive stripes thereon are then secured between two rollers to the surface area to be provided with the adhesive.

Inserts enclosed in the shipping case minimize damage due to shifting of the box blank stacks, provide added resistance against case failure during transit, and cooperate with the automated unloading machine to facilitate removal of the box blank stacks from the shipping case.

Abstract: In a method of emptying from a case a compressible load consisting of carton blanks, prongs penetrate through preformed perforations in opposite side walls of the case and push the load away from those walls, an upper portion of the case is partially severed by knives along respective paths at those walls, other cuts are formed across the top wall along the other two side walls of the case, suction cups pull away that upper portion, the load is received between support fingers, the load and the lower portion of the case are turned through 180 degrees in a vertical plane, the inverted lower portion is removed from the load by suction cups, and a gripping head seizes the load and removes it from between the support fingers.

Abstract: A method for withdrawing from a hopper collapsed sleeve type end loading cartons having face contacting panels in one of which panels a pair of apertures are formed and for initiating set up of the carton into open ended condition, the method comprising sequentially engaging and withdrawing collapsed cartons from the hopper with pick up devices slidably mounted on a pair of support rods, arranged so that one end of each support rod extends through one aperture in one of the face contacting carton panels and into engagement with the other face contacting panel so as to initiate a set up condition of the carton.

Abstract: An enclosed article carrier having upper sloping and panels to conform to the shape of the end articles in the carrier. The end panels are comprised of dust flaps adhered to overlapping upper and lower end flaps. Each dust flap is connected to the adjacent edge of its side panel along angled fold lines, the bottom edge of the dust flap being connected to the side panel adjacent the bottom panel of the carrier. Each dust flap has a cutout extending from its outer edge to a point spaced from the juncture of the fold lines. The carriers are thus strong enough to resist bowing during loading, resulting in well-aligned end panel flaps.

Abstract: A tube type carton formed from a unitary blank of paperboard and having at each end closure panels defined by a pair of opposed dust flaps and opposed major and minor closure flaps. The major flaps and two opposite side wall panels of the four side panels are trapezoidal. The remaining two opposite side wall panels are square but of different size. A pair of rectangular interior tucking panels joins one edge of the smaller square side wall panel to the shortest edge of one of the two opposite trapezoidal side wall panels, these interior panels being tucked into the interior of the carton. By virtue of the tucking, the cross-section of the tube is changed from rectangular to trapezoidal. The fully erected configuration of the carton is that of a truncated, right, four-sided, rectangular pyramid.

Each wall panel is provided with a top closure flap. The flaps are in overlapping relation when the carton is in a set up mode. One of the closure flaps is the outermost flap and has a dispensing opening formed therein. Another of the closure flaps subtending the outermost flap is provided with an aperture in registry with the dispensing opening when the flaps are in overlapping relation whereby the dispensing opening communicates with the carton interior. Mounted on the outermost flap is a fitment formed of thin material. The fitment includes a base section affixed to the exposed surface of the outermost flap circumjacent the dispensing opening, and a cover section adjustably mounted on the base section for movement between open and close positions.

Abstract: Notches are formed in the oppositely disposed side closure flaps of a carton to provide clearance for tucking blades to extend into the load storage compartment to tuck the distal panel of each side closure panel in behind its proximal panel.

Abstract: An improved packaging tray for an "In-Line" film wrapping machine incorporates reinforced side walls and friction-engaging planar side surfaces adapted to prevent slippage between the transport belts of the wrapping machine and thus avoid loss of tray/machine registration, miswrapped packages, machine damage and machine downtime.

Abstract: An envelope handling system for removing envelopes from an upper level conveyor, placing them in stacks on a lower level bucket conveyor, removing the stacks from the bucket conveyor and side-loading them into cartons, and sealing the cartons, conveying the cartons to a packing area, and forming the cartons into a horizontal column for placement into shipping containers. The system includes a spider feeder for removing the envelopes from an upper level conveyor and discharing them downwardly in a vertical direction, pivoting bottom fingers for receiving envelopes from the feeder and collecting them into a stack, hold back fingers for intercepting envelopes in a second stack above the bottom fingers, and transfer fingers for compressing a stack collected on the bottom fingers and urging the bottom fingers downwardly to place the stack onto the conveyor.

Abstract: A reclosable dispensing package which has a thin plastic fitment mounted over a cutout area in the closure flaps of a seal end carton. The fitment is affixed to the outer (last-folded) major flap. When the carton is flattened tubular form, the caliper of the fitment-equipped closure flaps is minimized by providing a second cutout area in the inner (first-folded) major flap, sized and located to receive a projecting end of the fitment therein. Minimizing caliper permits shipment in more compact form and enables packing machine operators to place greater numbers of cartons in the machine hoppers.

Abstract: A center special slotted container is shown which is manufactured from sheet of corrugated paper material. The blank is formed such that top and bottom flaps provide parallel edges in knock-down manufactured condition when the manufacturer's glue joint is made up. Before the glue joint is firmly set, this knock-down carton is readily processed in a squaring device of a folder-gluer (a Flexo folder-gluer is an example) to prove a quality manufactured carton, and overcome out-of-square defects.

Abstract: This relates to providing internal compression in packages of the type utilizing a wrap around carton. Instead of utilizing locking cut outs provided for receiving articles to be packaged, special compression cuts are formed in the closure panels of a wrap around carton so that the compression cuts are independent of the locking cut outs thereby permitting one chain and lug arrangement to be utilized in conjunction with numerous types of packages. The lugs are carried by compression chains located in a plane below the support plane of the articles to be packaged with the lugs being pivotally mounted on pins and normally having downwardly sloping positions for engaging in the compression cuts when the closure flaps are in their generally vertical depending position. The lugs are swingable upwardly to generally horizontal positions with the closure panels. Each lug carries a finger having a nose particularly configurated for automatically entering and centering within a compression cut.

Abstract: A reclosable dispensing package which has a thin plastic fitment mounted over a cutout area in a closure flap of a seal end carton when the carton is in flattened tubular form. The caliper of each flattened tubular sleeve is adjusted to approximately match that of the fitment-equipped closure flaps, the adjustment being effected in regions spaced from the fitment to provide areas of mutual contact on adjacent sleeves which serve to maintain the sleeves in parallel relationship when they are stacked in the hopper of packaging equipment. Such adjustment can be accomplished, for example, through the use of mutually opposed cartonboard embossments, or of thickened glue seams or by fluffing the outside score lines.
