The container for product has a bottom wall and a lateral wall of tubular extension up to an annular and surrounding an opening for access to the inner volume. The container is of the type without cover or part that can be lost, including two distinct protrusions, projecting from the lateral wall in order to get a closed configuration, wherein the two protrusions are simultaneously: projecting opposite the bottom wall, from the annular end; and sealed to each other so as to form a sealing zone in order to hermetically close the opening. The container has two gripping portions, offset and distributed on the two protrusions and arranged outside of the sealing zone, which makes it quick to open. The container is recyclable, formed for example based on laminated paper or cardboard.

The invention is directed to straight, consistent body scores on plastic corrugated boxes and a process for making the body scores.

A method for manufacturing a paperboard bottle and spiral-wound paperboard bottle. The bottle has a tubular body portion, a shoulder and neck portion having a circular cross-section narrowing from the body portion to a circular mouth. The paperboard bottle is a liquid packaging board having thermoplastic polymer coating on both sides. The method includes cutting a planar elongated blank from a packaging board sheet. Protecting exposed cut raw edge of the first longitudinal edge against absorption of liquid. Securing the first end of the blank to a rotatable mandrel having a rotation axis (x) and an outer shape corresponding to the shape of the bottle. Rotating the mandrel to wind the blank spirally onto the mandrel, so that the longitudinal edges overlap applying heat-sealing energy and pressure, onto the overlapping longitudinal edges to form a bottle with hermetically sealed spiral seam and removing the mandrel from inside the bottle.

The invention is directed to a balanced process for extrusion of a plastic corrugated sheet or blanks, and subsequent converting of the blanks into plastic boxes. The process includes conveying the blanks to a plurality of forming stations for incrementally forming features on the blank needed for forming a box. The present process is performed at a slower speed than typical paper corrugated forming.

The present invention is a method for producing an elongated protective layer for the shape-forming material of a blank, in which a protective layer is applied onto a web fed base material or sheet base material. The protective layer is applied beyond the edges of the web fed base material or sheet base material on one side or two sides in order to form a free edge that is not fastened to the base material. The multi-layer material is then cut or punched along the outline of a blank. In the places where an elongated protective layer is produced, the cutting or punching is done directly along the free edge, taking into account a margin for the elongated portion of the protective layer of the blank. The invention protects the end faces of a material for a shapeable container.

A container of paper or paper-like material, having a sleeve and having a bottom and/or a cover, wherein the bottom and/or cover and the sleeve are connected in substantially liquid-tight fashion in the region of a bottom skirt and/or cover skirt. The sleeve is composed of a sheetlike blank, and wherein regions adjoining a first side edge and adjoining a second side edge, situated opposite the first side edge, of the blank are laid one on top of the other so as to form an overlapping side seam and connected to one another by material-bonding engagement, wherein at least the region adjoining the first side edge forms a step which is offset relative to the rest of the blank.
