Abstract:
A method and an apparatus for realizing cartons for packing includes feeding a cardboard band (2) for packing along an advancement direction (A) which is parallel to the development direction of the cardboard band (2) and making a first score line (II) and a second score line (12) on the cardboard band (2), so as: to identify a central sector; a first lateral sector (4), and a second lateral sector (5). The method further includes identifying regions of band (8) on the carton (2), making on each region of band (8) at least a first cut (21), a second cut (22), a third cut (23) and a fourth cut (24) oriented transversally so that a first closing wing (49), a first reinforcing wing (51) a second reinforcing wing (52), a second closing wing (50), a third reinforcing wing (53) and a fourth reinforcing wing (54) are defined. The band of carton (2) is cut transversally so as to separate the regions of band (8) from one another, thus obtaining cartons (I) for packing.
Abstract:
A machine for forming a container from a blank of sheet material includes a forming station and a compression station. The forming station is configured to form a reinforcing corner assembly from first and second reinforcing panels extending from an end panel of the blank. The compression station is configured to rotate side panels and end panels of the blank to be substantially perpendicular to a bottom panel of the blank. The compression station includes a plurality of plows at least partially defining a plunger opening, and a plunger vertically movable through the plunger opening. The plurality of plows are configured to rotate the side panels and the end panels towards the interior surface of the bottom panel.
Abstract:
A blank for constructing a crush-tolerant container includes a first side panel, a bottom panel, a second side panel, and a top panel coupled together in series. At least one cutout and at least one bridge portion are defined along a first fold line between the top panel and the first side panel. The at least one bridge portion and the at least one cutout are configured to maintain the top panel in a plane spaced above a top edge of the first side panel when the container is formed and the top panel is not under a stacking load, and to allow the top panel to move downwardly such that at least a portion of the top panel is substantially co-planar with the top edge of the first side panel when the container is formed and the top panel is under the stacking load.
Abstract:
A self-supporting flexible film container is disclosed that includes a container base and a flexible film attached to the container base that forms a container wall and defines a packing region within the container. The container wall has at least one support column, such as a tubular support column, integrally formed therein. A method of conforming the container includes providing a web of flexible film, forming tubular support columns in the web of flexible film and forming a container from the web of flexible film containing the support columns. The support columns can be formed by ploughing and forming the web of flexible film.
Abstract:
Embodiments of a reinforcing tape for preventing or minimizing structural instability of corrugated paper board that may be exposed to an aqueous liquid are disclosed. The reinforcing tape comprises (i) an extruded mesh substrate including a plurality of parallel thermoplastic polymer elements oriented in a first direction and a plurality of parallel thermoplastic polymer elements oriented in a second direction, wherein the thermoplastic polymer elements are spaced from 0.5 cm to 5 cm apart; and/or (ii) a nonwoven substrate comprising a plurality of randomly-oriented thermoplastic polymer fibrous elements. The reinforcing tape has a machine-direction trapezoidal tear strength of at least 2.3 kg. Embodiments of a method for using the reinforcing tape also are disclosed.
Abstract:
The invention relates to a method and apparatus for erecting part of a container, specifically containers referred to as “trays” in the art. The method includes using a mandrel to fold four walls (14, 16) of the container (12) but return side walls (16) to a slanted, lower intermediate position relative to upstanding end walls (14), so that a finger (30) can pivot to fold a pillar (24) from an end (26) of an extension (20) of the end walls (14) and retract over the side walls (16), before a pressing element (36) raises the intermediately positioned side walls (16) to upstanding positions where they are attached to the pillars.

Abstract:
A packing box has a bottom panel, end panels raised from first edges of the bottom panel, side panels arranged adjacently to the end panels, edge panels connected to side edges of the end panels via outer panel fold lines, fold-back panels arranged on inner side surfaces of the edge panels, inner panels arranged on inner side surfaces of the end panels, and reinforcing panels continuously formed with the fold-back panels via first fold lines and the inner panels via second fold lines. The reinforcing panel 16 is formed in an inwardly projecting manner between the fold-back panel and the inner panel. Any of the first and second fold lines positioned on a side closer to the outer panel fold line than a projecting top portion is arranged away from the outer panel fold line by a distance.
Abstract:
A blank of sheet material for forming a polygonal container is provided. The blank includes a bottom panel, two opposing side panels, two opposing end panels, and a reinforcing panel assembly extending from a first side edge of a first end panel of the two end panels. The reinforcing panel assembly includes a corner panel extending from the first side edge of the first end panel, a first reinforcing side panel extending from a side edge of the corner panel, a second reinforcing side panel extending from a side edge of the first reinforcing side panel, a reinforcing corner panel extending from a side edge of the second reinforcing side panel, and an inner end panel extending from a side edge of the reinforcing corner panel. The corner panel and the reinforcing corner panel are configured, upon articulation of the blank, to be positioned into face-to-face relationship to form a corner wall of the container extending from a side edge of an end wall of the container to an end edge of a side wall of the container.
