Disclosed is a packaging box which includes a box body. The packaging box includes a cavity defined in the box body and a side wall surrounding the cavity, a support frame that disposed on an inner side of the side wall, and a bottom plate that is disposed in the cavity and at an end of the support frame. The support frame is integrated with the box body, an opening is provided in the box body, and the support frame is formed by bending the side wall located at the opening toward the cavity.

The invention relates to a method for providing a packaging for modified atmosphere packaging, which method includes the steps of: providing an unfolded sheet for folding a box; folding the unfolded sheet to a box having at least an access opening and flange parts bordering the access opening, which flange parts compose an endless circumferential flange; providing a plastic foil; heating the plastic foil; pressing the heated plastic foil against the inner wall of the box and covering the circumferential flange, such that the plastic foil is laminated to the box. The invention further relates to a packaging.

The present invention relates to material packaging made of corrugated cardboard sheet having a polygonal cross section, comprising lateral walls, a lower plane forming the bottom of the packaging, and an opposite upper plane. It comprises at least one portion (25, 26) projecting with respect to the upper plane. The bottom (30) comprises at least one surface portion (15, 16) that is cut out over a portion of the thickness of the cardboard sheet, is compressed and in the form of a non-through hollow, referred to as a hollow portion, the shape of which matches the projecting portion, in line with the latter and arranged to fit together with the projecting portion of the packaging below.

A machine for forming a container from a blank of sheet material is provided. The blank includes a reinforcing panel assembly for forming a reinforcing corner assembly. The machine includes a hopper station for storing the blank in a substantially flat configuration and a forming station for forming the blank into the container. The forming station includes an initial forming station that rotates a first portion of the reinforcing panel assembly with respect to a second portion of the reinforcing panel assembly, and a secondary forming station having male and female forming members with shapes corresponding to an interior shape and an exterior shape of the reinforcing corner assembly, respectively. The male and the female forming members are configured to form the reinforcing corner assembly by compressing together the first and second portions of the reinforcing panel assembly.

A multi-sided container has more than four sides and foldable panels integrally arranged with respect to each other. A first panel and a second panel form a contiguity with a first fold line disposed therebetween. The first panel and a third panel form a contiguity with a second fold line disposed therebetween. The third panel is not parallel with and not orthogonal to the first panel. A first strength reinforcement feature includes a first slot having a first planar edge oriented orthogonal to the first panel and orthogonal to a z-axis, and a second planar edge oriented orthogonal to the second panel and parallel to the z-axis. The third panel includes a cut edge proximate the first fold line having a third planar edge oriented orthogonal to the third panel and orthogonal to the z-axis. The third planar edge is disposed in a same plane as the first planar edge.

An apparatus forms boxes with curved corners from a die-cut sheet. A forming matrix delimits a forming cavity by guides counterposed in pairs along two orthogonal axes. The guides define a die-cut sheet support plane. A forming head inserts inside the cavity to push the die-cut sheet to form a box. Vacuum gripping devices are arranged outside the cavity in opposite positions along the second axis and each grip from underneath the die-cut sheet to hold it on the support. Pusher devices are arranged outside and near one of the corners of the cavity. Each pusher device raises one side flap of the die-cut sheet from the support plane. An electronic control unit operates the main gripping devices, pusher devices and forming head according to the following sequence: actuating the gripping devices; actuating the pushers; deactivating the gripping devices; and inserting the forming head in the forming cavity.

A method for forming a composite structure may include positioning a composite sheet adjacent to a die opening. A portion of the composite sheet may be constrained between a first forming surface and a second forming surface. The first forming surface may be spaced a gap distance from the second forming surface. The gap distance may be substantially equal to or greater than the sheet thickness. The composite sheet may be urged through the die opening and along a third forming surface to form a composite bottom from the composite sheet.
