Methods for securing a shrinkable film to a paperboard substrate and methods for making paperboard containers therefrom. In one or more embodiments, a band of adhesive may be applied about a perimeter of a paperboard substrate having a first edge and a second edge opposed to one another and a third edge and a fourth edge opposed to one another. The band of adhesive may surround a first area that is substantially free from the adhesive. A second area that may be substantially free from the adhesive may be located along a portion of the third edge, between the first and second edges. The first area and the second area may be separated by the band of adhesive. A shrinkable film may be secured to the paperboard substrate with the adhesive to produce a paperboard blank. The third edge and the fourth edge may be overlapped to form a sidewall. A bottom panel may be secured to the sidewall at or adjacent the second edge. The first edge may be curled to form a brim.

The invention relates to a method for manufacturing a covering structure for a cardboard package comprising a tubular body made up a cardboard material. The covering structure comprises a flat assembly of three materials: (1) a cellulosic material covered with a reactivatable barrier material over the face thereof oriented towards a safety membrane, making up a lid cardboard, (2) a laminating part arranged between said lid cardboard and the safety membrane, with a shape conjugated to the shape of the opening of the tubular body, made from paper, or paper whereof the face oriented towards said lid cardboard is coated with a material having barrier and sealing properties, and (3) a safety membrane, made up of a paper coated with at least one reactivatable barrier material on the surface thereof not oriented towards the laminating part.

A cup having a bottom and a sidewall attached to the bottom, wherein the sidewall preferably comprises a rolled rim at its upper edge opposite to the bottom, wherein the sidewall comprises a single layer or a plurality of layers, wherein at least one of the layers is produced from a paper or carton material, wherein at least one shaping is shaped into at least one of the layers of the sidewall, wherein the shaping is at least partially ring-shaped, wherein the shaping extends at least partially over the perimeter of the sidewall, wherein the shaping is inwardly or outwardly directed, wherein the shaping is compressed in height such that an edge of the shaping touches an opposite segment of the shaping and/or that both edges of the shaping touch each other and are joined together.

Processes, assemblies, and sleeve blanks for forming a two-piece paper container are provided in which the sleeve blank includes an adhesive printed onto the sleeve blank while the sleeve blank is still part of the paper web. The adhesive can optionally be printed onto the sleeve blank in-line with printing a graphic on the sleeve blank prior to providing the sleeve blank to a container forming machine that wraps and seals the sleeve blank to a bottom blank.

An apparatus for forming an upper edge of a paperboard container includes a pocket including a shell having a cavity with a mouth configured to receive the container along an axis such that the rim extends beyond the mouth. A workstation includes a forming member having a first forming surface which is actuatable toward the axis from a retracted position spaced from the rim to an extended position lying adjacent an upper end of the rim, and a forming segment having a second forming surface which is actuatable along the axis and the forming member in response to axial movement thereof such that the second forming surface is positioned spaced from a lower end of the rim. The second forming surface is actuatable along the axis towards the first forming surface to form the rim therebetween.

A device for setting up containers along fold lines from flat blanks, having a forming station including a forming tool having a displaceable forming punch, and a backing device for setting up the containers from the blanks, and having a discharging device for carrying away the set-up containers from the forming station. The forming station is designed for folding a circumferential functional edge. The device is designed for turning the set-up containers after the forming station and for pushing the containers over preceding containers for forming a container stack having the container openings thereof facing forward.

Processes, assemblies, and sleeve blanks for forming a two-piece paper container are provided in which the sleeve blank includes an adhesive printed onto the sleeve blank while the sleeve blank is still part of the paper web. The adhesive can optionally be printed onto the sleeve blank in-line with printing a graphic on the sleeve blank prior to providing the sleeve blank to a container forming machine that wraps and seals the sleeve blank to a bottom blank.

A packaging for modified atmosphere packaging includes a flangeless cardboard tray having a bottom and an upstanding peripheral wall. A plastic flange is arranged on top of the edge of the peripheral wall. The plastic flange has in cross-section a first part extending horizontally, substantially parallel to the bottom of the tray, a second part depending from the first part downward along the outside of the peripheral wall and a third part depending from the first part, opposite of the second part, along the inside of the peripheral wall. A plastic barrier foil is adhered to and lines the inside of the cardboard tray and extends over the plastic flange to fix the plastic flange onto the flangeless cardboard tray.

A 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 to establish fluid communication between an interior of the container and the environment outside the container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

Processes, assemblies, and sleeve blanks for forming a two-piece paper container are provided in which the sleeve blank includes an adhesive printed onto the sleeve blank while the sleeve blank is still part of the paper web. The adhesive can optionally be printed onto the sleeve blank in-line with printing a graphic on the sleeve blank prior to providing the sleeve blank to a container forming machine that wraps and seals the sleeve blank to a bottom blank.
