The present disclosure relates to a method of forming a paperboard packaging container from a rectangular body blank, the method comprising the steps of providing a rectangular body blank having a first end edge and a second side edge, forming a tubular container body from the rectangular body blank, sealing together the first and the second side edge of the body blank, closing the first end opening by pressing a paperboard disc into the first end opening, pressing the first end of the tubular container body into a curl forming portion of a curling tool, filling the packaging container with bulk solids, and closing the second end opening.

A carton assembly machine for cartons (17) for packing articles (15, 15′), comprising means for feeding an unassembled carton in a feed direction, the said carton having a plurality of side flaps or panels (18, 19) whose folds are essentially parallel to the said feed direction folded onto a central portion (25) of the carton, the said machine further comprising a movable element (26) designed to move between a first position away from the route of the carton and a second position in which the said element is designed to be Inserted underneath, at an edge (27) of at least one of said side flaps or panels (19), so that the latter is raised with respect to the said central portion, in particular, in cooperation with the carton feeding.

A rectangular blank has sides X and Y, where a and b are side dimensions, h is height, and r is width, or width reduced by height h, of the periphery region R of the finished packaging. The method includes: producing folding lines B in the blank parallel to side Y at these distances from the latter: B.sub.1: a.sub.1=h; B.sub.2: a.sub.2=h+a; B.sub.3: a.sub.3=2h+a; severing of two severing lines T, each starting from opposite sides X, along one of the folding lines B, or the extension thereof; selecting the distance between two end points E.sub.T of the severing lines T which are closer to an axis of symmetry S.sub.1 parallel to the side X, such that the distance corresponds to a side B″ of the finished packaging or length of a side M of a packaging insert.

A container comprising a bottom and a sidewall extending upwards from the bottom and terminating at an upper free edge, said upper free edge of the sidewall forming an opening of the container, said sidewall and said bottom comprising an outer paperboard layer and a thin inner plastic foil layer, formed in a thermoforming operation, said upper free edge of the sidewall comprising a rim portion extending past the outer surface of the paperboard layer of the sidewall. The rim portion comprises a rolled up portion of an upper portion of the outer paperboard layer of the sidewall, said rolled up portion being covered by a portion of the thin inner plastic foil layer. In this way, a stiff upper rim is provided, while allowing the use of a very thin inner plastic foil layer.

Forming a cardboard blank includes making two score lines on a cardboard sheet to define a central sector with three portions and two lateral sectors. Four cuts are made in a direction transverse to the score lines to form in one lateral sector a first closing flap and first and second reinforcing flaps and, in the other lateral sector, a second closing flap and third and fourth reinforcing flaps. The first and second closing flaps are folded at respective score lines, and one portion folded to cover a flank of an article on another portion so the first and third reinforcing flaps project. A third portion is folded to cover another flank and an upper article face so the second and fourth reinforcing flaps project. A band folds the first two reinforcing flaps towards the first closing flap and the third and fourth reinforcing flaps towards the second closing flap.

A container with a deep recessed bottom end construction is provided. The container includes an inner receptacle having a sidewall and a bottom wall defining an interior volume within the receptacle. The container further includes an outer sleeve wrapped around the inner receptacle with a lower end extending below the lower edge of the receptacle to form a deep bottom recess within a lower portion of the container. The lower end of the receptacle sidewall has a taper angle that is different from a taper angle of an upper portion of the sidewall. The lower end of the receptacle sidewall may engage or contact the inner surface of the outer sleeve. The outer sleeve may include reverse bend and/or a second bottom wall onto which a lower end of the receptacle may sit.

A method for producing reusable packaging from a carton. A rectangular blank has sides X and Y, a total area xy, 2(a+h)≤x≤3(a+h)+a, and y−2(h+r)≤b≤y, where a and b are side dimensions, h is height, and r is width, or width reduced by height h, of the periphery region R of the finished packaging. The method includes: producing folding lines B in the blank parallel to a first side Y at these distances from the latter: B.sub.1: a.sub.1=h; B.sub.2: a.sub.2=h+a; B.sub.3: a.sub.3=2h+a; severing of two severing lines T, each starting from opposite sides X, along one of the folding lines B, or the extension thereof; selecting the distance between two end points E.sub.T of the severing lines T which are closer to an axis of symmetry S.sub.1, which is parallel to the side X, such that the distance corresponds to a side B″ of the finished packaging or length of a side M of a packaging insert.

A container with a deep recessed bottom end construction is provided. The container includes an inner receptacle having a sidewall and a bottom wall defining an interior volume within the receptacle. The container further includes an outer sleeve wrapped around the inner receptacle with a lower end extending below the lower edge of the receptacle to form a deep bottom recess within a lower portion of the container. The lower end of the receptacle sidewall has a taper angle that is different from a taper angle of an upper portion of the sidewall. The lower end of the receptacle sidewall may engage or contact the inner surface of the outer sleeve. The outer sleeve may include reverse bend and/or a second bottom wall onto which a lower end of the receptacle may sit.

A one-piece, plastic-free blister package is disclosed. The package is formed from a one-piece card comprising a front support card having a window and a rear portion. The rear portion comprises a plurality of sidewalls and a plurality of tabs which can be folded to form a cavity to hold a small product. The package is then assembled by bonding part of the rear portion to the front support card through the application of heat and pressure. The package encloses the product, which is visible to consumers through the window cut on the front support card.

A rectangular blank has sides X and Y, where a and b are side dimensions, h is height, and r is width, or width reduced by height h, of the periphery region R of the finished packaging. The method includes: producing folding lines B in the blank parallel to side Y at these distances from the latter: B.sub.1: a.sub.1=h; B.sub.2: a.sub.2=h+a; B.sub.3: a.sub.3=2h+a; severing of two severing lines T, each starting from opposite sides X, along one of the folding lines B, or the extension thereof; selecting the distance between two end points E.sub.T of the severing lines T which are closer to an axis of symmetry S.sub.1 parallel to the side X, such that the distance corresponds to a side B″ of the finished packaging or length of a side M of a packaging insert.
