An extensible bearing element of a tool for sealing a bottom or a lid of a cardboard package on a body of said package has a generally polygonal shape and a cross-sectional profile. The bearing element is formed by two parallel extension sections extending along an extension direction, each connected, at one of their ends, to a bearing section. The extension sections and the bearing section define an inflation cavity. The extension sections are configured to extend along the extension direction when the bearing element is inflated. The bearing section comprises a substantially flat, free bearing surface that contacts the package body. The bearing surface extends along a plane substantially normal to the extension direction. The bearing section further comprises, at the junctions with the extension sections, beveled release portions. An inflation device comprising such an extensible bearing element is also described.

Shown and described is a plastic element for a package, comprising: a main body of plastic, and a flange for fastening a composite material of a package, wherein the plastic element is produced from a thermoplastic material. In order in the case of single-use packages to create a low-cost possible way of obtaining information about the state of content of the packages, it is proposed to arrange an electrical, in particular electronic element on the plastic element or integrate it in the plastic element. Also shown and described is a package with such a plastic element.

A blank 10 for forming a disposable cup, the blank including a cardboard sheet designed to be formed into a body of a cup, the blank including an edge 12 in a form of a first arc for forming the bottom edge of the cup, and a folding line for forming the rim of the cup, wherein the folding line for forming the rim of the cup contains a first folding line 14 formed by a plurality of interconnected arc-shaped folding lines 16 each arcing to the opposite direction than the first arc, and wherein a foldable wing 18 extends form each arc-shaped folding line, the wings being configured to be folded towards the center of the formed cup to lock onto each other to form a cover over the opening of the cup. The present application also provides a disposable cup formed from the blank, and a method for preparing a disposable cup.

A composite container having a paperboard hollow body with top and bottom open ends. The body is formed by a sidewall with inner and outer surfaces. The composite container includes a body liner extending peripherally about the inner surface of the body and a base connectable to the bottom open end of the hollow body. The base includes a sidewall sized and shaped to fit snugly within the bottom open end of the body. The sidewall is permanently coupled to a bottom portion of the liner. The composite container also includes a collar connectable to the top open end of the hollow body. The collar has a peripheral portion that abuts the top open end and an inner circumferential flange sized and shaped to fit snugly within the top open end of the body. The inner circumferential flange is permanently coupled to a top portion of the liner. The peripheral portion has regions of weakened strength so that the section of the peripheral portion that abuts the top open end can be removed, thereby allowing a user to rapidly remove the coupled collar, liner and base from the hollow body.

The invention relates to an extensible bearing element (28) intended to be arranged in a tool for sealing a bottom or a lid of a cardboard package on a body of said package, with a generally polygonal shape.

The extensible bearing element (28) has a cross-sectional profile comprising two parallel extension sections (36) extending along an extension direction (E), each connected, at one of their ends (36E), to a bearing section (38), such that the extension sections (36) and the bearing section (38) define an inflation cavity (30).

The extension sections (36) are configured so as to extend along the extension direction (E) during the inflation.

The bearing section (38) comprises a substantially flat free bearing surface (40), configured to come into contact with the package body, the bearing surface (40) extending along a plane substantially normal to the extension direction (E).

The bearing section (38) further comprises, at the junctions with the extension sections (36), beveled release portions (42).

The invention also relates to an inflation device (6) comprising such an extensible bearing element (28).

The present disclosure relates to a paperboard sealing disc for use in a packaging container, comprising a peripheral edge portion surrounding a tear-open part having a push-tab and a pull-away part. The tear-open part is delimited from the peripheral edge portion by a first cutting line in the first side and by a second cutting line in the second side. Said first cutting line being provided at a distance d1 from said sealing disc outer edge, and said second cutting line being provided at a distance d2 from said sealing disc outer edge. The push-tab at least partly delimited from the pull-away part by a folding line. At the push-tab d1>d2 and at the pull-away part d2>d1. Furthermore, d1 at said push-tab is substantially the same as d2 at said pull-away part and d2 at said push-tab is substantially the same as d1 at said pull-away part.

The present disclosure provides a paperboard packaging container comprising a tubular paperboard container body, a container bottom and a container lid. The container body comprises a container body abutment edge at the container opening. The container body has an inner surface facing towards an inner compartment in the packaging container and an outer surface facing away from the inner compartment. The container lid comprises a lid collar having an abutment edge adapted for abutting against the container body abutment edge, and a lid plug-in portion. The plug-in portion has a side surface extending in the longitudinal direction and faces the inner surface of the container body, when the container lid is in a closed position. The lid collar is made of the same material as the container body and the lid collar is delimited from the container body by a slit or by weakening means.

A bottle featuring a tubular body portion (13) formed in one piece by a spiral wound tube manufacturing process. A shoulder portion (11, 15) is joined to a first end of the body and a base portion (14) is joined to a second, opposite, end of the body potion. The shoulder portion is comprised of an inner shoulder (15) and an outer shoulder (11) that provide mutual support for a neck (12) and to provide a structurally familiar beverage package shape such as a flask or bottle. The neck may comprise a frustum shaped end (26) that engages with a mating surface (23) of the inner shoulder (15).
