  • Patent number: 5735429
    Abstract: A corrugated fiberboard bulk shipping container for fluent materials has an outer box and an inner box inserted therein. The outer box is rectangular in cross section, and the inner box comprises two sleeves, each in the form of irregular octagons. During assembly of the container, flaps carried on the outermost of the two inner sleeves fold over the opening at one end of the inner sleeve and engage one another to fix the octagonal shape of the inner box. Extended corner portions on the flaps fit substantially into the outer box and stabilize the inner box within the outer box.

  • Patent number: 5535940
    Abstract: A container board for flat food products, made from a single piece of paper board such as a pizza, which includes a bottom wall surrounded by upright side walls and a pair of diagonally extending front corner walls is described and includes a lid portion having a top wall connected to a rearwardly disposed side wall of said bottom wall by a fold line forming a hinge. The lid portion is movable between a closed position covering the bottom wall and an open position. The lid walls are formed of a double ply having an upper edge provided with a top opening recess. The lid portion includes a top wall and said walls, the latter being conformed to be received in closely spaced relationship to the inner surfaces of the upright bottom side walls when the lid portion is in the closed position.

  • Patent number: 5533666
    Abstract: An octagonal box structure comprising eight upstanding side wall panels and eight closure flaps integrally connected to one another and to the side wall panels for folding inwardly along a generally horizontal score hinge line to close an end of the box structure. The side wall panels include four smaller panels having a width dimension of about 20 to 40 percent of the width dimension of the narrowest pair of the remaining four side wall panels. The closure flaps have a width corresponding to the width of the side wall panel from which they depend. Four of the closure flaps include diagonally extending score hinge lines to permit each of these closure flaps to fold inwardly in partial overlapping relationship upon itself and the next adjacent closure flap to form a closed end of the box. The diagonal score lines are formed at an angle between about 20 to 25 degrees relative to an extension of the vertical score lines which define the width of each closure flap.

  • Patent number: 4767051
    Abstract: A box blank for a produce box has four side panels which are hinged together along score lines. An extension flap adjacent one of the side panels is wrapped around and glued to the panel at the opposite end of the blank. The side two major and two minor panels each have an appropriate length flap attached to one edge which is unscored and is to be folded into the top, and a flap on the other edge which is appropriately scored for folding to form the bottom of the box. More specifically, two minor and two major panels are attached to edges of the side panels, at a scored hinge line. Each minor panel has a triangle scored thereon, the base of the triangle being the hinge line with the side flap. One end of each major panel is attached to a minor panel; the other end of each major panel has a score line, roughly defining a triangle which will overlap 1/2 of the triangle scored onto the minor flap.

  • Patent number: 4598526
    Abstract: A system for boxing printed forms uses half-slotted (hsc) containers and apparatus for assembling the containers, filling them with forms, compressing the forms, applying a lid, and strapping the lid on the container. Two parallel conveyor systems are used in the apparatus. A forms infeed accumulator conveyor infeeds stacks of forms to a form-dropping mechanism aligned above a parallel box-receiving conveyor. A folded box infeed tray, a box opening mechanism, and bottom flap folding members assemble boxes one at a time. A box pusher transfers the formed box onto the receiving conveyor and lateral guides and sensor controls precisely position the box beneath the form-dropping mechanism. The dropping mechanism has two rows of live roller-fingers abutting end to end and are movable laterally apart to drop the forms into a box below.

  • Patent number: 4565316
    Abstract: A carton for packing and shipping produce such as asparagus, the carton being formed in two pieces or sections. The first section of the carton is a lower box body having a bottom, two opposed upstanding side walls, a rear wall, and a front panel hinged to the bottom of the lower box body and foldable to a position wherein it slopes inwardly from vertical to vary the cross sectional area of the interior of the carton from top to bottom thereby supporting the asparagus stalks. The second section of the carton is an upper box cover having a top, two side walls, a front wall and a back wall, being dimensioned to telescope over the lower box body so that the outside of the assembled carton has a rectangular prismatic configuration.

  • Patent number: 4545781
    Abstract: A combination of a self-opening shopping bag and a coupon packet is disclosed together with apparatus and a method for making same. A flat coupon packet containing coupons is affixed to the front panel of the bag. The coupon packet is sized and positioned widthwise between the side gussets of the bag and spaced apart from the bottom of the bag so that, when the bag is folded flat, only the front and rear panels of the bag underlie the packet. The coupon-applying apparatus is designed and positioned to apply coupons at the beginning of the bag-making procedure. It includes a glue applicator mounted adjacent the former of the bag-making machine for applying a strip of glue to a side of the continuous sheet opposite the forming means, the strip extending lengthwise of the sheet in a predetermined lateral position. A packet feeder is mounted on the former just downstream of the glue applicator for feeding coupon packets lengthwise of the paper flat onto the continuous sheet upon the strip of glue.

  • Patent number: 4537586
    Abstract: A combination of a self-opening shopping bag and a coupon strip is disclosed together with apparatus and a method for making same. An elongated coupon strip containing coupons is affixed inside the front panel of the bag. The coupon packet is sized and positioned widthwise between the side gussets of the bag. The strip has a perforated margin portion and only the margin is adhered to the bag so that the coupons can be readily detached. The coupon-applying apparatus includes a coupon strip roll stand positioned in line with the bag paper roll stand. A glue applicator is mounted on the coupon strip roll stand for applying glue to the margin of the strip. The coupon strip meets the underside of the bag paper as the paper travels around an outfeed roller of the bag paper roll stand. The coupon roll stand includes a brake for tensioning the strip. Spacers are mounted on the former and spaced apart for the coupon strip to pass between them.

  • Patent number: 4497408
    Abstract: A stackable container with locking lid especially suitable for use in packaging grapes and other soft fruits comprises a container body having a lid of resiliently deformable material hinged to one side wall and a ledge on an adjacent end wall. The lid rests on the ledge. A stacking cleat on said adjacent end wall extends to a plane above the lid. A recess in the inner face of the stacking cleat is coplanar with the lid. A laterally-extending locking tongue extension of the lid coplanar with the recess is dimensioned for removable insertion into the recess upon closing the lid, thereby releasably locking the lid to the cleat.

  • Patent number: 4421253
    Abstract: A disposable container assembly which is especially useful for containing, shipping and dispensing liquids or semi-liquids in bulk. It comprises a knocked-down fiberboard container body and end structure which can be set up on a pallet into a substantially rigid multi-sided polygonal drum-like container for receiving a flexible plastic bag that is to be filled with the substance to be dispensed. The bag is provided with a dispensing spout that is locked in dispensing position in one side of the fiberboard container to hold the bag in position in the container during filling, with its outer end exposed and which has a diaphragm type seal at its inner end. For dispensing, normally this seal is ruptured by a special cooperating probe which is inserted through the exposed outer end of the spout to withdraw the contents of the bag but in other cases the bottom of the bag can be ruptured directly through an opening in the pallet.
