Abstract: A carton is provided with an automatic bottom panel, which extends from a side panel, and has two converging reverse-scored fold lines, which extend outwardly from the side panel. One end flap featuring an angled score is folded up from the automatic bottom panel and is glued to its body panel. Adhesive is applied only above the diagonal folding score, leaving the unglued section free to fold in reverse in the bottom formation. The other end panel bottom flap is folded inwardly in the box joining process and a second of that flap with another diagonal score is folded in reverse for glue application. As the main panels are folded in the final gluing process the reverse folded glued section adheres to the outside surface of the previously mentioned major bottom flap. As the carton is brought into square during the erection process, the flaps self-form into a solid, full-overlapping bottom.

Abstract: According to the practice of this invention, the noted unwanted adhesion between the second panel and the first panel attendant the formation of the sideseam joint is eliminated by providing the second panel with a cutout. That portion which is cut out corresponds in form to the triangular cutout or truncated portion at the tapered end of the sideseam forming fifth panel. In this way, when compression of the first panel against the sideseam panel and the first panel occurs, there is no hot and sticky exposed area of the first panel which will adhere to the second panel.

Abstract: A blank for erecting a carton has 180° fold lines with a compressed area at each end and a slit joining the compressed areas.

A filled carton is closed by advancing it through the central opening of a V-shaped member to increasingly fold the carton top panels. The closed carton 100 is sealed by advancing it through a second V-shaped member and into contact with a pivotally supported sealing device.

The panels include first, second, third and fourth panels that are separated from adjacent side panels by longitudinal crease lines. A plurality of top panels define a sealed top. A plurality of bottom panels define a sealed bottom. The bottom panels extend from respective, adjacent side panels and separated from their respective side panels by a transverse crease line. Each bottom panel has a length relative to the transverse crease line. The bottom panels are contiguous with adjacent bottom panels and are separated from adjacent panels by the longitudinal crease lines. The bottom panels include rectangular major and minor panels opposing each other and each having a length. The length of the minor panel is less than the length of the major panel. The minor panel has a tab extending from an end thereof and separated from the minor panel by a tab crease line.

Abstract: A machine for container formation by folding a die-scored paperboard structure to close flaps shaped by the scoring that serve as the top and bottom of the container. A scored paperboard sheet is loaded onto a male pedestal inner pattern such that the foldable top and bottom container portions extend beyond the pattern, whereupon armature driven semicircular outer patterns, having upper and lower fingers adapted to be driven by corresponding fluid driven pin stabilizers, close upon the sheet. While closed over the sheet, the pins are activated to move the fingers inward on the inner pattern and force fold the container along the score lines, followed by automatic retraction of the pins and outer patterns. The container is thus pre-folded in preparation for shipping as a flat paper form that is ready for folding on the crease lines thus formed. One or both flaps of the container can be folded along the crease lines to form a closure at one or both ends.

Abstract: A container includes a four-sided body configured to be folded from an expanded, opened position to a collapsed, flattened position. The four-sided body includes a set of four walls.

Abstract: A cigarette carton comprises opposite front and rear walls, opposing side walls, a top portion and a generally open bottom portion. The bottom portion comprises a plurality of closure flaps connected to at least several of the front, rear and side walls, and a horizontal hinge line connects each closure flap to its respective carton wall. Each closure flap has a fully open position where the flaps are inside the carton and rest on the carton walls to which they are connected to thereby enable cigarette packs to be placed in and removed from the carton. The closure flaps have a closed position where the flaps are positioned at an angle slightly inside the carton to retain the contents of the carton.

Abstract: A carton having a primary elevated bottom portion extending along the length of an exposed raw paperboard edge to protect the carton and to prevent moisture absorption. The carton also having a secondary elevated bottom portion substantially within the primary elevated portion and having an elevation greater than the primary elevated bottom portion. Additional elevated portions are provided for additional raw paperboard edges on the bottom of the carton. The present invention alleviates the problem of cartons having soggy bottoms since the point of absorption, the raw paperboard edge, is elevated above the moisture which may be present during distribution from the packaging machine to the retailer. The elevated bottom portion is actually inverted into the carton with planar portions resting on the surface to support the carton.

Abstract: A bottom end closure of a carton to be heat- and pressure-sealed has four substantially rectangular panels (P6, P7-P9, P12 and P14-P16) of which the panels (P7-P9 and P14-P16) are divided by score lines (S3, S7 and S13, S17) into inner, triangular sub-panels (P8 and P15) and outer triangular sub-panels (P7, P9 and P14, P16) and have central lugs formed by pairs of small, rectangular sub-panels (P10, P11 and P17, P18) providing for gas-tightness at the apices (A1 and A2) in the sealed closure. Score lines (S4, S6 and S14, S16) provide lines of weakness across the whole widths of the roots of the central lugs, so that the lugs, when each folded upon itself, can adjust to the orientation of an outwardly folded panel (P13) during tucking of the panel (P13) inwards of the lugs, which are sandwiched between the panels (6 and P13). In the blank, the lugs and the panels (P6 and P13) are so dimensioned that they can interdigitate with the corresponding lugs and panels of the bottoms of a row of identical blanks.

Abstract: A new carton blank configuration and a method of folding it to provide a liquid-tight, nonwicking carton or container bottom is disclosed. The scoring pattern and bottom panel configuration of the carton make possible the formation of a carton bottom having no exposed edges of the carton blank on the inside of the container without folding or slitting any bottom panel prior to the carton folding and sealing process. The carton blank is shaped and scored for folding and is substantially a flat container bottom. An extension tab extending from one of the two bottom panels allows for a nonwicking surface to be formed and tucked into the interior of the carton bottom during the bottom-forming process as the edges of the two bottom panels contact each other. The inside surface of the bottom panel not having an extension tab contacts the extension tab, folding the extension tab back along a score line.
