Abstract: A bliss-type, corrugated paperboard container having an open top for transporting and displaying fruit, vegetables and the like has a main piece, which provides a bottom element and opposed first side elements, and two bliss pieces which are adhesively attached to the main piece and provide opposed second side elements. The second side elements include an inner panel having extremities which are separated from the first side elements. Diagonal pieces, attached to the extremities of each inner panel, extend to the first side panels, and second side flaps extend from the diagonal pieces to overlie portions of the first side panels. An outer panel of the second side element extends between the first side elements. Indexing tabs have first ends which are connected to the inner panels and second ends which are connected to the outer panels. The indexing tabs are bent 180° between the first and second ends. The indexing tabs fit into slots located in the bottom of a stacked container.

Abstract: A multi-ply paperboard container for use as a bulk material bin has elongate rectangular cross-sectioned tubular inner and outer shells having walls that are spaced apart from one another. Rectangular panels, having a width less than the width of the walls of the shells, are located between and adhesively bonded to each overlying pair of walls. Thus, gaps are formed between the inner and outer shell at each corner of the container. The corners of the inner and outer shells are crushed to provide wide soft corners. These gaps and crushed corners permit the container to be easily knocked down to a flat configuration without a substantial amount of spring-back. The container includes a bottom cap having end flaps inserted between the inner and outer shells or between adjacent plies in the inner or outer shells, and the outer shell has closure flaps which fold over the bottom cap to keep the end flaps in place. When loaded, the bottom cap and closure flaps prevent the container walls from bending outwardly.

Abstract: An upright tubular shell has a top end, a bottom end, and a plurality of side-by-side sidewalls. The shell is constructed of a plurality of layers of paperboard material. A first one of the sidewalls defines a first portion adjacent a first upright edge of the first sidewall and has a thickness less than the thickness of the adjacent portion of the first sidewall. The first portion also comprises less than all of the plurality of layers of the paperboard material. The first portion overlaps and is attached to a second one of the sidewalls. A flexible impervious liner with an attached fitment is located within the shell. An outer opening is defined in one of the sidewalls proximate the bottom end for receiving a portion of the fitment. A bottom cap defines a first opening, a second opening, and a third opening. The first opening overlays the second opening. The outer opening is interdisposed between and aligned with the third and first openings.

Abstract: A container for fluid material including an upright tubular shell having a top end and a bottom end. The shell includes upright first sidewalls having a first width and an upright second sidewall having a second width that is less than the first width. The second sidewall is interdisposed between the pair of first sidewalls. The bottom end of the shell is closed, and a flexible impervious liner with a fitment attached for emptying the liner of fluid materials is located within the shell. A lower portion of the second (narrow) sidewall defines an outer opening with a vertical dimension greater than a cross-sectional portion of the fitment to be inserted therethrough. The second (narrow) sidewall has greater resistance than the first (wide) sidewall to transverse motion, which decreases the likelihood of structural failure of the container as a result of transverse motion of fitment and associated sidewall.

Abstract: A collapsible container is formed from a blank of foldable sheet material. The container includes a plurality of upright first wall panels, second wall panels, and corner panels foldably connected to and disposed between a first wall panel and a second wall panel. The first wall panels, second wall panels and corner panels act together to define a predetermined area. Bottom forming side flaps are foldably connected to the bottom edges of the first wall panels and extend therefrom towards one another into the predetermined area, wherein the side flaps extend laterally beyond the first wall panels. Bottom forming end flaps are foldably connected to the bottom edges of the second wall panels and extend therefrom towards one another into the predetermined area. Portions of the end flaps overlie portions of the side flaps when both the end flaps and the side flaps are respectively extending towards the predetermined area.

Abstract: A paperboard container for storing and transporting fluids has a tubular shell formed from interfitting inner and outer shell pieces. The shell is enclosed at its bottom end by a base having projecting flaps which are sandwiched between the shell pieces and flaps located at the bottom of the outer shell cover the base. A flexible liner located in the shell has a fitment at its upper end which permits the liner to be filled and emptied. The top of the shell is covered with inner cap and a closure means which are separated from one another and contain aligned openings which the fitment passes through. A fitment lock, which immovably engages the fitment, fits between the inner cap and closure means and is adhesively affixed to at least one of them. The fitment lock, and the inner cap and closure means act in conjunction to prevent movement of the fitment and to provide the lateral and longitudinal stability necessary to permit a hand pump to be installed in the fitment.

Abstract: A container is formed of a pair of paperboard tubular walls open at both ends and one telescoped within the other. A liquid impervious transparent liner is confined within the inner wall and the ends of the walls are closed by top and bottom closures. A fitment is attached to the liner and extends outward through the tubular walls for connection of a dispensing control valve. One or more liquid level indicating windows is provided by forming registering openings in the inner and outer tubular walls and pressing a transparent cup into each opening in the inner tubular wall before telescoping the inner and outer tubular walls together. A peripheral flange on the cup abuts the outer surface of the inner tubular wall and is secured in place by being sandwiched between the inner and outer tubular walls. In an alternative container construction, a single container wall is used, and the cup flange is abutted against and, if desired, secured to the confronting inner or outer surface of the container wall.

Abstract: A paperboard carton is formed from a single blank of generally rectangular shape which is cut and scored along lines which provide corner panels at the four corners and middle panels separated from the corner panels along one pair of opposite sides of the blank by two laterally spaced pairs of two laterally spaced cut lines connected at their inner ends by an angularly directed cut line, and along the other pair of opposite sides of the blank by two laterally spaced pairs of two laterally spaced score lines which define between them an angle corner panel. The inner ends of the middle panels are defined by score lines which, together with the angle cut lines, define the peripheral margin of a central bottom panel. The middle panels form the ends and sides of the carton.

Abstract: A container is formed of a pair of paperboard tubes opened at both ends and one telescoped within the other. A bottom inner closure cap closes the open bottom end of the inner tube and has a plurality of peripheral flaps inserted between the inner and outer tubes. One of the flaps is hinged to a tab portion of the inner closure cap which extends partially into the inner cap and terminates at its inner end in a transverse score line to allow the tab to be hinged outward of the cap for inserting a flexible plastic liner into the inner tube. A fitment on the liner is extended outward through, aligned openings in the flap and inner and outer tubes. An outer bottom cap covers the inner bottom cap and the fitment extends outwardly through an opening in its peripheral wall. With the assembly supported on a pallet, liquid is filled into the liner from its open top, the liner then is closed within the inner tube and a top outer cap is fitted over the top end of the outer tube.

Abstract: Multiple ply corrugated or solid fibre paperboard having any desired number of plies is made by adding to the delivery end of conventional corrugator or paster apparatus, between the cut-off section and the stacker section, a glue applicator system controlled, preferably by computer program, to apply glue only to the desired areas of those outfeeding paperboard sheets which are to be bonded together to form the desired multiple ply paperboard. The glued and unglued paperboard sheets proceed to the stacker section where they are stacked one upon another. The paperboard sheets having an interface of glue are bonded together to form the multiple ply end product and the paperboard sheets having no glue interface allow subsequent separation of the plurality of multiple ply corrugated paperboard end products in the stack. Offsetter mechanism is provided to offset corresponding margins of certain plies of a group before depositing them in the stacker, to form a splice joint.

Abstract: A carton for shipping and displaying a shotgun is disclosed. The carton is formed from a unitary blank of horizontally-extending, stock cover panels each having a hingedly-attached, vertically foldable panel which together divide the carton into separate front and rear compartments, one for snugly packaging the stock portion and the other receiving the barrel portion of the shotgun which are packaged as separate items. A V-shaped carton portion is foldably attached to one of the vertically foldable panels and is adapted to fit over the barrel and hold it stationary within the carton. An angular flap extends from one of the stock corner panels and is disposed to protect the edge of the V-shaped carton portions at one end thereof against damage by a barrel ring disposed in contact therewith.

Abstract: An octagonal dispenser carton for packaging coils of band saw blade stock in bulk lengths is formed from a flat corrugated cardboard blank having a main octagonal center section, rectangular side wall flap sections foldably joined to each edge thereof, and polygonal end wall flaps extending from said side wall sections, said end wall flaps combining when in folded position to securely hold the side walls and without reinforcement to contain a coil of blade stock.

Abstract: A device for driving loads on a horizontal roller conveyor support between pick-up and delivery stations including a carriage mounted to travel back and forth below the conveyor level. The lower end of an upstanding lever arm is pivoted on the carriage and at the upper end of the arm a load engaging cylinder or roll is mounted with its axis forwardly (i.e. in a downstream direction) adjacent the vertical center line of the arm which is yieldably urged to remain at right angles to the plane of conveyor support. In the latter position the top of the roll is slightly elevated by a fraction of an inch above said load support plane. In operation at the pick-up station near the upstream end of carriage travel the roll can freely rotate under a load and the lever is thereby angularly set at an acute angle in the load driving direction.
