Abstract: A blank for making a single or dual cavity container and the corresponding containers. In a dual cavity embodiment, the blank is scored to define a pair of bottom panels, two pairs of end panels, and a pair each of lateral and opposing side panels. The pair of opposing side panels are connected together along a mutual upper edge. A lid for each respective cavity extends from the first and second lateral side panels, and each lid terminates in a tuck flap for engaging at least one of the corresponding opposing side panels and the corresponding pair of end panels. Each adjacent pair of walls (e.g., end panel-lateral side panel; end panel-opposing side panel) has a gusset integrally formed therebetween. The gussets are appropriately folded and adhered to the outside of one of the adjacent walls. Because both cavities are formed from a unitary blank with no seams below the upper edges of the walls, leakage is prevented when the container is maintained in an upright orientation.

Abstract: A kit for making boxes from paper card stock. The kit has a flat plate with a guide rail with a vertical edge projecting above the surface of the plate parallel to one edge of the plate. A scoring groove traverses the plate parallel to the vertical edge of the guide rail. One or more spacing strips, each having a vertical edge, may be placed between the vertical edge of the guide rail and the scoring groove to vary the depth of the box. The overall size or "footprint" of a box made in accordance with the invention is determined by the distance of the scoring groove from the nearest vertical edge and the size of the blank card stock employed. Two identical sized card stocks are used for each box. A slightly wider spacing strip is used to form the top than the spacing strip used to form the bottom of the box. This also makes the depth of the box bottom slightly greater than the box top.

Abstract: A kit for making boxes from a paper card stock is described. The kit comprises a flat plate having a guide rail with a vertical edge projecting above the surface of the plate parallel to one edge of the plate. A scoring groove traverses the plate parallel to the vertical edge of the guide rail. One or more spacing strips, each having a vertical edge, may be placed between the vertical edge of the guide rail and the scoring groove to vary the depth of the box. The overall size or "footprint" of a box made in accordance with the invention is determined by the distance of the scoring groove from the nearest vertical edge and the size of the blank card stock employed. The card stock preferably comes in two sizes for each size box, one for the bottom and one for the top. The card stock used for the top is slightly larger than the stock used for the bottom so that the same spacers may be used for scoring folding lines for both the top and the bottom and, at the same time, providing a mating fit therebetween.

Abstract: Method and apparatus are provided for effecting sealing of a carton panel such as the top panel to a manufacturer's joint in such a fashion that carton erection from a pre-formed carton blank can proceed in an in-line manner without any changes in the direction of carton transport as it is erected, filled and sealed. Panel sealing is accomplished by folding the manufacturer's joint over a free end of the panel, applying an adhesive to the manufacturer's joint while it is in overlying relation with the panel, lifting the panel over the manufacturer's joint, and urging the panel into engagement with the manufacturer's joint so as to become bonded thereto. Top panel sealing in the foregoing manner proceeds without the necessity of using the carton contents as a mandrel against which the manufacturer's joint is otherwise ordinarily folded, thereby permitting the carton to be erected and sealed along its manufacturer's joint in the absence of product received within the carton.

Abstract: A method of forming a sift-proof seal for closure of a box having a plurality of folded flaps, the seal being formed by an adhesive strip pattern. The flaps are moved linearly toward a plurality of nozzles which extrude adhesive in a pattern of closely spaced adhesive strips. A flap having such an adhesive pattern is brought into contact with a second flap to compress the pattern of adhesive therebetween. The spacing between adjacent strips of adhesive is such that the folding of the flap causes merging of the adhesive to form a continuous strip of adhesive, thereby forming a box closure. The adhesive pattern is limited to a first outside edge of the first flap, with each remaining outside edges receiving a sift-proof continuous line of adhesive.

Abstract: The invention relates to a high-integrity closure, sift-proof carton [10], a method and an adhesive dispensing apparatus for producing same. Foamed hot melt adhesive is dispensed in parallel strips from dispensing guns onto the flaps [20], [22], [30], [32] of the carton [10], which are thereafter folded down to close the carton [10]. The strips can be spaced so that a continuous tight adhesive seal is formed, especially by providing a strip pattern interdigitating when the flaps contact each other. Since all strips are provided in parallel, while the carton is moved with respect to the dispensing apparatus, application of adhesive is fast and reliable.

Abstract: A machine or machine section for squaring folded container blanks has a conveyor for conveying slotted and partially folded container blanks. A folding device completes folding of each container blank while being conveyed by the conveyor. A gauge plate is inserted in a slot in each of the slotted and partially folded container blanks. A mechanism moves the gauge plate in timed sequence with the conveyor, inserts the gauge plate in the slot before completion of folding of the respective blank in order to "square" the folded blank, and then withdraws the gauge plate from the slot. Overlapping flaps of each folded blank may be tacked together during "squaring" by drops of hot melt adhesive which subsequently hold the flat folded blanks square while the conventional slow drying water soluble glue dries. The "squaring" arrangement may be incorporated in a conventional gluer/folder machine.

Abstract: A glue detecting system uses linear filament lamps and photodiodes mounted in the ends of nonreflective tubes to distinguish between diffuse and specular reflections from the surface of a moving article. Sensor photodetectors are positioned directly over the locations where glue beads are intended to be present; reference photodiodes observe the surface where no glue is intended. The spacing between certain photodiodes in the direction of movement of the article may be used to determine the velocity of the article, and the intensity of the reflections is used to determine the presence of glue in the desired areas, and the presence of unwanted glue in other areas; the duration of the specular reflections is used to determine the volume of glue present. An alarm circuit indicates an insufficient amount of glue in the desired areas or the presence of unwanted glue in undesired areas.
