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 double-walled cup and a process for production of the cup are described. The cup includes an inner cup and a tube-shaped outer sleeve, which is formed from a blank of paper material joined at its ends. The tube-shaped outer sleeve is slid axially onto a prefabricated inner sleeve and secured. The tube-shaped outer sleeve is formed from a flat blank by joining the ends of the blank before being slid on, whereby the ends of the blank are joined by an adhesive applied to a limited area of the outer sleeve. The ends of the blank are joined by a thermoplastic material in the form of an adhesive, which for example can be a hot-melt adhesive or a sealing varnish.

A clamshell packaging for airtight packaging of foodstuff includes a tray folded out of a single sheet. The tray has at least two adjacent pool parts, each pool part having a bottom wall and upstanding walls arranged around the circumferential edge of the bottom wall. The adjacent pool parts are hingedly connected to each other along an upper edge of a respective upstanding wall, so the adjacent pool parts can be hinged on top of each other to form a closed box. A circumferential, horizontal flange is arranged to the tray to at least some upper edges of the upstanding walls. A plastic barrier foil is arranged in the pool parts and extends onto and substantially covers the flange. The flange includes a seal zone extending along the length of the flange. The seal zone is line symmetrical along the hinge line at the upper edge of the connected walls.

A container for articles, including: an upper end and a lower end; a first lateral wall and a second lateral wall; a bottom, including a first bottom wall and a second bottom wall. The container includes means for blocking the bottom, including a first abutment flap fixed to the inner surface of the first lateral wall and including a lower abutment edge; and a second abutment flap including an upper abutment edge and connected to the second bottom wall. The second abutment flap is folded against the inner surface of the first lateral wall for abutting, with the relative upper abutment edge, the lower abutment edge of the first abutment flap.

Materials for coating paper sleeve blanks are provided, wherein the paper sleeve blank includes a multilayer coating. The multilayer coating includes a barrier layer and a top coat. At least two polymeric layers, including a top coat, are added to one side of the paper sleeve blank and the bottom blank. A container forming machine wraps and seals the multilayer coated paper sleeve blank to the coated bottom blank.

A container may include one or more walls and one or more expandable portions. For example, a container may include four walls and a first expandable portion may be movable between a collapsed position and an expanded position. The container may also include a second expandable portion that is movable between a collapsed position and an expanded position. The first and second expandable portions may allow a wall of the container to move between a first position and a second position when the first and second expandable portions are moved between the collapsed position and the expanded position.

A method for producing a bowl formed by a tray closed by a sealing film involves preparing a blank where a first and a second couples of crease lines delimit a bottom panel, two first and two second side walls, each first side wall provided of an internal flap and an external flap delimited by respective third and fourth crease lines, each second side wall provided of an internal flap and an external flap delimited by respective fifth and sixth crease lines, erecting the blank into a tray, folding the internal and external flaps of each first side wall about the respective third crease line and the internal and external flaps of each second side wall about the respective fifth crease line, applying adhesive on the internal and/or external flaps of each first and second side walls, folding the external flap of each first side wall about the respective fourth crease line and the external flap of each second side wall about the respective sixth crease line, forming a rim, applying adhesive on gaps between abutting ends of rims of adjacent first and second side walls, and attaching the sealing film on the rims.

Disclosed is a production machine which is used in producing the cornet cone packages used in the packaging of cornet-type ice-creams and which provides for the cornet cone packages to be vertically fed and brought into a cone shape by being crimped.
