A method of and an apparatus for erecting a carton, and a method of and an apparatus for closing a carton. The carton has 180° fold lines with a compressed area at each end and a slit joining the compressed areas. A carton is erected by moving the blank in a first direction against a stop to form a first set of 90° folds, holding the blank stationary with a suction while pushing the blank in a second direction to form a second set of 90° folds, erecting the carton. 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 is sealed by advancing it through a second V-shaped member and into contact with a pivotally supported sealing device.

1. A method of automatically erecting a carton from a carton blank comprising a pair of blanks, each blank including a side panel having substantially parallel first and second end edges and substantially parallel top and bottom edges extending substantially perpendicular to the end edges; an end panel having first and second side edges substantially parallel with the side panel end edges and having substantially parallel top and bottom edges, said end panel extending from said side panel with the end panel first side edge joined to the side panel second end edge to define a first 90° fold line and with the end panel top and bottom edges being extensions of the side panel top and bottom edges respectively; a top panel having first and second side edges substantially parallel with the side panel top edge, and having substantially parallel first and second end edges, said top panel extending from said side panel with the top panel first side edge joined to the side panel top edge to define a second 90° fold line and with the top panel first and second end edges being extensions of the side panel first and second edge edges respectively; a bottom panel having first and second side edges substantially parallel with the side panel bottom edge, and having substantially parallel first and second end edges, said bottom panel extending from said side panel with the bottom panel first side edge joined to the side panel bottom edge to define a third 90° fold line and with the bottom panel first and second end edges being extensions of the side panel first and second end edges respectively; a first, top fold-in panel having first and second end edges substantially parallel with the end panel top edge, and having substantially parallel first and second side edges, said first fold-in panel extending from said end panel with the first fold-in panel first end edge joined to the end panel top edge to define a fourth 90° fold line, with the first fold-in panel side edges being extensions of the end panel first and second side edges, respectively, and with the first fold-in panel first side edge joined to the top panel second end edge to define a first 180° fold line; a second, bottom fold-in panel having first and second end edges substantially parallel with the end panel bottom edge, and having substantially parallel first and second side edges, said second fold-in panel extending from said end panel with the second fold-in panel first end edge joined to the end panel bottom edge to define a fifth 90° fold line, with the second fold-in panel side edges being extensions of the end panel first and second side edges respectively, and with the second fold-in panel first side edge joined to the bottom panel second end edge to define a second 180° fold line; each fold-in panel having 180° fold lines extending from a point on the second end edge thereof substantially midway between the first and second side edges thereof to points at the intersections of the first end edge thereof and the first and second side edges thereof, the pair of blanks overlying each other with the end panel of one blank overlying a portion of and joined to the side panel of the other blank at their respective second side and first end edges and the fold-in panels of the one blank overlying portions of and joined to the top and bottom panels of the other blank at their respective second side and first end edges, the joined panels between the blanks defining further fold lines at their joined edges, said method comprising:positioning the carton blank on an erecting surface with a stop member adjacent the end panel of one of the blanks; advancing the carton blank in a first direction against the stop member with a first actuator to cause the blanks thereof to form 90° folds on the first 90° fold line, the first and second 180° fold lines and the further fold lines to partially erect a carton; applying suction beneath the bottom panel of the underlying one of the blanks; advancing the carton blank in a direction perpendicular to the first direction with a second actuator with the suction maintaining the bottom panel of the underlying one of the blanks substantially stationary to cause the blanks to form 90° folds on the 90° fold lines defined between the bottom panels and their adjoining side panels and between the bottom fold-in panels and their adjoining end panels and to form 180° folds on the 180° fold lines in the bottom fold-in panels and on the 180° fold lines and on the further fold lines defined between the bottom fold-in panels and their adjoining bottom panels to close the bottom of the partially erected carton; and sealing the bottom panels of the two blanks together. 2. The method according to claim 1, further comprising forming the carton blank from a single piece which is folded and connected at its ends to provide said overlying blanks.3. The method according to claim 2, including connecting said ends of said single piece together using one of the group consisting of a sealing strip provided at an end of said single piece and sealing tape.4. The method according to claim 1, further comprising forming the carton blank from two blanks formed separately and connected to one another at opposite ends thereof to provide said overlying blanks of said carton blank.5. The method according to claim 4, including connecting said ends of said two separate blanks together using one of the group consisting of sealing strips at the ends of the two blanks and sealing tape.6. The method according to claim 1, further comprising filling the erected carton from the top and closing and sealing the top panels of the carton.7. A method of automatically closing the bottom of a carton comprising:providing a partially erected carton blank for forming the carton, the partially erected carton blank having first and second side panels and first and second end panels which bridge the side panels, and first and second bottom panels and first and second bottom fold-in panels which bridge the bottom panels, the first and second bottom panels and first and second bottom fold-in panels being adjacent respective ones of the side panels and end panels; securing one of the bottom panels of the partially erected carton blank in an erecting position; pressing against the carton blank with an actuator on a side of the carton blank opposite said one bottom panel in a direction to advance the carton to cause the first and second bottom panels and the first and second bottom fold-in panels to fold inwardly, closing the bottom of the carton, while maintaining said one of the bottom panels in said erecting position. 8. The method according to claim 7, wherein said securing and maintaining include applying suction to said one bottom panel for securing the bottom panel in said erecting position.9. The method according to claim 7, wherein said direction is at a right angle to a 90° fold line defined between the one bottom panel and a side panel adjacent the one bottom panel.10. The method according to claim 7, including sealing the closed bottom panels of the carton together.
