A box formed from a plastic corrugated material with soft score lines is provided. The soft score lines are formed to enable the top flaps of the box to lay substantially flat against the outer surface of the box when folded to an open position.

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.

The present invention relates to systems and processes for cutting and creasing corrugated cardboards, and more specifically, to digital system and processes for cutting and creasing corrugated cardboards, wherein the system includes an array of cutting elements that can be dynamically configured to cut and/or crease a wide range of contours.

A system for forming a pressware product from a web of a roll of material includes a positive mold, a negative mold, a heating element, an actuator, a force sensor, and a control system. The positive mold forms a top surface of the pressware product. The negative mold forms a bottom surface of the pressware product. The heating element is coupled to the positive mold or the negative mold. The actuator shifts the positive mold or the negative mold to cut and form the pressware product in a single stroke. The force sensor detects the forming force applied by the actuator, and the control system directs the actuator to adjust the forming force.

A system for forming a pressware product comprises rollers, a scoring tool, a scoring station actuator, a forming tool, and a forming station actuator. The rollers pull the web along a path having an angle. The scoring tool receives the material from the rollers and includes a vertically shiftable scoring punch with an edge that extends about an outline of the pressware product and a striker plate. The scoring station actuator shifts the scoring tool to form a slot in the web. The forming tool receives the scored web and includes a vertically shiftable positive mold assembly and negative mold assembly. The forming station actuator shifts the positive mold assembly to press against the web and form the pressware product.

A multi-orifice nozzle suitable for drawing a plurality of line rules in parallel, line rules disposed in parallel drawn using the multi-orifice nozzle, and systems and methods for using such line rules for impressing a substrate with a plurality of line indentations disposed in parallel.

A pressed crease-forming member includes a strip-shaped member having a crease-forming portion formed with three or a larger-than-three odd number of ribs extending in the longitudinal direction of the strip-shaped member with one of the ribs located at the widthwise center of the crease-forming portion and each half of the remaining even number of ribs arranged on either side of the center rib. At least the top of the center rib, namely, the rib located at the widthwise center of the crease-forming portion, is chamfered. Grooves are formed between the adjacent ribs. The ribs are arranged such that the tops of the ribs are formed, as a whole, into a convex shape. The bottom of each groove is recessed beyond the tops of the ribs on both sides of the groove.

A ventilation board is manufactured from a corrugated board comprising at least one depressed portion on both sides of the board in such a way that flutes of the corrugated layer between said depressed portions are exposed to form a plurality of passageways for passage of fluid across the board, in other words, from one side to the other side of the board. The depressed portion is formed by forming a cut on the surface of each side of the board in such a way that the cut penetrating from one side of the board passes through the corrugated layer of the corrugated board but does not pass through the other side of the corrugated board, and depressing the cuts in such a way that the flutes between the depressed portion get exposed in order to provide passageways for passage of the fluid across the board.
