The invention relates to a polygonal container comprising a tubular polygonal body (10) with an even number of flat faces (11) numbering more than four, which is formed by a strip of corrugated cardboard (19) rolled up at least two full turns and adhered to itself by means of lines of glue (30) transverse to the channels of the corrugated cardboard, forming a multilayer wall (13); a base body (20) defined by a base panel of cut and folded stiff double-faced corrugated cardboard (24) attached around an end portion of the tubular polygonal body (10). The method comprises forming the tubular polygonal body by means of rolling the strip of corrugated cardboard around a polygonal rotary drum (51) and subsequently attaching to a base body (20).

A carton comprising an inner construct comprising a plurality of inner panels extending at least partially around a first interior and an inner locking tab foldably connected to at least one inner panel. An outer construct can comprise a plurality of outer panels extending at least partially around a second interior. The outer construct can comprise an outer locking tab foldably connected to at least one outer panel, and the inner locking tab and the outer locking tab can cooperate to limit movement between the inner construct and the outer construct. The carton also can comprise an engagement feature comprising a cover panel that is at least partially separable from the at least one outer panel. The inner locking tab of the inner construct can extend along the engagement feature in the outer construct so that the inner locking tab can be engaged when the cover panel is at least partially removed for facilitating movement of the inner construct and the outer construct relative to one another.

In an embodiment, a portion control container can have a body and a lid sealed to the body. The lid can have defined therein a spout-type opening. The spout-type opening can be defined by an initiation region having 100% cut-through the lid that transitions to a pattern of reduced strength having less than 100% penetration through the lid. The container can remain sealed until the lid is separate from the container along the seal to provide a dip-type opening or the lid material is torn at the initiation region and pattern of reduced strength to define a spout-type opening for squeeze dispensing of the product from the container.

A cooler includes panels defining a storage area; corner panels; top panels forming a lid; a first handle panel connected to a first top panel and having a slot formed therein; a second handle panel connected to a second top panel and having a slot formed therein; and a first tab panel connected to a corner panel and having a tab defining a recess, the tab being configured to extend through the slot of the first handle panel and through the slot of the second handle panel for locking the handle panels and top panels in a fully closed, carry configuration of the cooler. Portions of the first and second handle panels are received within the recess defined by the tab. The second handle panel can be unlocked and the storage area accessed while holding the cooler with the first handle panel.

The present invention relates to material packaging made of corrugated cardboard sheet having a polygonal cross section, comprising lateral walls, a lower plane forming the bottom of the packaging, and an opposite upper plane. It comprises at least one portion (25, 26) projecting with respect to the upper plane. The bottom (30) comprises at least one surface portion (15, 16) that is cut out over a portion of the thickness of the cardboard sheet, is compressed and in the form of a non-through hollow, referred to as a hollow portion, the shape of which matches the projecting portion, in line with the latter and arranged to fit together with the projecting portion of the packaging below.

A system for automatically forming packaging boxes comprises a folding station comprising four folding units adapted to fold panels of cardboards blanks to form substantially cuboid boxes or lids or combinations of a box and a lid, some of said panels in the folded state forming pairs of two panels running substantially parallel to each other in a processing direction, in which the blanks are transported through the system, and orthogonal to a width direction of the blanks, which is the orthogonal direction to the processing direction in the plane of the blanks, one or more glue application units adapted to put glue on at least one panel of each of said pairs of two panels, a feeding conveyor to convey a cardboard blank into the folding station, a curing station adapted to take over the boxes or lids or combinations of a box and a lid folded in the forming station from the folding station, said curing station comprising holding structure to form-fittingly hold said pairs of panels and to guide the boxes or lids or combinations of a box and a lid through the curing station.

A carton comprising an inner construct that can comprise a plurality of inner panels extending at least partially around a first interior. The inner construct can comprise first and second inner locking tab. An outer construct can comprise a plurality of outer panels extending at least partially around a second interior. The inner construct can be at least partially received in the second interior. The outer construct can comprise first and second outer locking tabs. The second inner locking tab and the second outer locking tab can cooperate to limit movement between the constructs in a closed configuration, and, when the second inner locking tab has been disengaged from the second outer locking tab, the inner construct and/or the outer construct can be movable from the closed configuration to an intermediate configuration in which the first inner locking tab and the first outer locking tab cooperate to limit movement between the constructs.

A packaging that can be unfolded and forms a circumferentially closed ring has vertically positioned sidewalls that are connected to each other by commonly embodied corners of a spatial shape. In at least two or more corner regions, support strips extending across a corner and provided with upwardly and downwardly projecting clamping flaps are pushed onto the top edges of the bottom sidewalls, the upwardly projecting clamping flaps form between them an insertion channel extending along the extension of the support strip into which the top sidewalls can be inserted, wherein the length dimensions and the spatial shape of the sidewalls below and above the strip plane correspond with each other. The sidewalls positioned on top of each other and connected by the support strips to each other form a common packaging with commonly formed flat outer surfaces, respectively.
