A box forming machine includes a converter assembly, a fold assembly, and an attachment assembly. The converter assembly converts sheet material into a box template. The fold assembly engages a first end of the box template and moves the first end of the box template to a predetermined position. The attachment assembly engages a second end of the box template and moves the second end of the box template toward and into engagement with the first end of the box template to attach the first and second ends of the box template together.

A method of erecting a carton from a blank, including: engaging the blank with a punch head against which the carton is formed, folding side portions of the blank against the punch head to form sides of the carton; folding outer portions of the side portions of the blank away from the punch head and against an external side of the carton; folding end portions of the blank against the punch head to form end portions of the carton; folding outer portions of the end portions of the blank away from the punch head and against an external end of the carton; and securing corner gussets formed between the side and end portions against sides or ends of the carton.

Fastener-free packaging includes a plurality of main panels, each main panel comprising an upper panel, a central panel, and a lower panel; at least one attaching connection feature located on at least one lower panel; and at least one receiving connection feature located on at least one lower panel, wherein each lower panel is connected to at least two other lower panels by an attaching connection feature connecting to a receiving connection feature such that all lower panels are connected together thereby forming a bottom.

A quality-control device (200) includes: an illumination system (202) for illuminating one peripheral face of each folding box, an image capture device (204) for forming a multiple image of the respective peripheral faces of a bundle of folding boxes, an image processing system (206) for: i) detecting within the multiple image each peripheral end of the slots of each box that separate its adjacent flaps, ii) generating a data set indicative of the geometry of each peripheral end, and iii) analyzing the data set to determine the width of each peripheral end.

A corrugated paperboard box is provided in which when flaps are bent, a perforated line along which the flaps can be separated from the box is less likely to break. Such a corrugated paperboard box includes a peripheral wall and top flaps, and is formed, at the boundary area between the peripheral wall and the top flaps, with a groove-shaped reverse scoreline recessed on the side of an outer linerboard, and a pair of groove-shaped recesses recessed on the side of an inner linerboard, and extending in parallel to each other so as to sandwich the area in which the reverse scoreline extends. The corrugated paperboard box is further formed, in one of the groove-shaped recesses, with a perforated line along which the top flaps can be separated from the peripheral wall. The top flaps can be bent along the perforated line toward the inner surface of the peripheral wall.

A system and method are disclosed for forming a container from a generally flat re-configurable blank. A first portion of an outward facing surface of a blank support device is positioned proximate a first portion of a blank while the blank is in a first orientation. While the first portion of the blank is maintained in the first orientation, a second portion of said blank is rotated from the first orientation, around a second portion of the outward facing surface of the blank support device to form a blank that has a generally tubular configuration. The system and method may provide that during the rotating of said second portion of said blank, the blank is engaged on a surface side which forms an inner surface of the generally tubular configuration. Also disclosed is a system and method that includes retaining a reconfigurable blank in a holding apparatus; applying adhesive to a surface of the blank while said blank is retained in the holding apparatus.

A folder/gluer unit includes an upper transfer belt that transfers a corrugated sheet in a direction of transfer, a pair of forming belts that abut against a folding surface which is formed by folding both end portions of the corrugated sheet in a width direction orthogonal to the direction of transfer and fold both of the end portions of the corrugated sheet in the width direction, a pair of folding bars that are disposed in the direction of transfer, abut against the folding surface at both of the end portions of the folded corrugated sheet in the width direction, and guide both of the end portions of the corrugated sheet in the width direction, a moving mechanism that moves the pair of folding bars in the width direction and in a vertical direction, and a control unit that controls the moving mechanism to adjust a position of the folding bar.

A container forming apparatus for forming a container from a blank includes a blank transfer station including an adhesive assembly having a plurality of adhesive applicators, and a compression station downstream of the blank transfer station, the compression station including a vertically movable mandrel and a forming tool below the mandrel. The forming tool defines a cavity therein and has an inner profile complementary in shape to an outer profile of the mandrel. Hot-melt adhesive is applied to a surface of the blank as the blank is transferred through the adhesive assembly. The blank is positioned beneath the mandrel, and the mandrel drives the blank downward into the cavity of forming tool. Compression plates fold panels of the blank, and the formed container includes a fully formed top flange.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.

A forming unit for a container from a blank of the container. The unit includes a conveyor and at least one equipment secured to the conveyor. The equipment includes a forming device moving with continuous movement and forming a container from the blank during a predetermined forming path on the conveyor.
