The disclosure relates to a method and apparatus for manufacturing a package with a rigid or semi-rigid container and a polymeric or plastic header with a reclosure, such as a zipper. The rigid or semi-rigid container is typically provided in a stack of flat containers. The header is sealed, glued or otherwise secured to the containers. The container, typically inverted, is filled, and the bottom is formed by folding and sealing the bottom portion of the container.

A flattenable volume-optimized container, having a prism-shaped layout, formed of at least eight mutually connected sidewall parts, of which sidewall parts, two respectively are essentially parallel to one another and have the same sidewall length, wherein, with respect to the center point of the layout, the sidewall parts are arranged at least essentially point-symmetrically, and at least one bottom part essentially perpendicularly alignable with respect to the sidewall parts and foldable between the sidewall parts, and hinged to at least two sidewall parts. The invention includes four of the sidewall parts having a length which is greater than the length of four other sidewall parts, and two sidewall parts mutually opposite with respect to the center point each have a folding line on their side median, by which the ring can be flattened and which are situated on the outer boundary of the flattened container.

Packaging container comprising a top part (110) comprising a pouring spout for pouring the contents of the container a tubular body part (120) comprising an upper end and a lower end, the upper end being joined together with the top part along a circumferential edge of the upper end of the body part, the body part further comprising a first group of crease lines (132) extending from a lower end of the body part towards its upper end. The top part comprises a recessed portion (117) and the recessed portion and the first group visually form one surface, wherein the one surface near the interface area between the first group of crease lines and the recessed portion of the top part provides gripping support for one or more fingers of a hand, when the packaging container is held by the hand and the remaining fingers during pouring the contents from the packaging container.

The present invention relates to a box, a blank, a set of blanks made from corrugated cardboard sheet and a method for forming a box having a polygonal section. The box has at least one centring tab (7) straddling at least one folding line (4) on its upper wall (2), cut out on its lateral sides (8), connected on one side to the upper wall (2) by a first joining line (10) and on the other side to the adjacent side wall (5) by a second joining line (6), a parallel and offset intermediate folding line (14) being provided such that the tab (7) forms a projecting portion (16) on account of the folding. The bottom comprises at least one perforated surface portion (18) which has a shape complementary to that of the tab such that the lateral edges of the recess are designed to cooperate in contact with the lateral edges of said tab, and is designed to fit into the projecting portion of a box from below.

A substantially paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal so as to establish fluid communication between an interior of the composite container and the environment outside the composite container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

A package for containing items having a flip-open package closure is provided. In some embodiments, the package includes a rigid package body and a flexible closure flap. The flexible closure flap is coupled to a hangtab portion of the package body such that the flexible closure flap moves from a closed position to an open position with respect to the package body based on a position of the hangtab portion. An upper edge of a front side of the package body engages the lower portion of the closure flap when the package is closed, while the lower edge of the closure flap is released from the upper edge upon pivoting backward of the hangtab portion. Such pivoting of the hangtab portion, and corresponding manipulation of the closure flap, may occur without directly contacting the closure flap.
