Embodiments of foldable containers, such as foldable produce containers, and related sheets and methods. In some embodiments, a sheet may comprise at least two adjacent, parallel, side panels, one of which may comprise a bendable tab, and the other of which may comprise a cutout configured to receive the bendable tab. This may allow for temporarily maintaining the two panels in position during a folding process to facilitate additional folding steps during the process. In some embodiments, a container may comprise one or more strapping flaps configured to facilitate tensioning of strapping material for strapping together multiple containers. These strapping flaps may be configured to engage a strapping material and may allow a single person to more easily tension the strapping material to strap multiple containers together.

Herein is provided a container including a plurality of sidewalls (3, 7, 9) connected to one another along foldlines, and a base. The base includes first, second, third and fourth base flaps (11, 13, 15, 17) connected along respective foldlines to respective sidewalls. The second and third base flaps (13, 15) are folded over the first base flap (11) and the fourth base flap (17) is folded over the second and third base flaps (13, 15). The fourth base flap (17) includes a base panel portion which forms part of the exterior of the base and a locking tab portion connected to a distal end of the base panel portion. The locking tab portion is inserted into the interior of the container through a slot defined by the first, second and third base flaps (11, 13, 15) to retain the base in a closed configuration. A cutline is provided extending inwardly from the side edge of the fourth base flap (17) on each side of the fourth base flap (17) at a transition between the base panel portion and the locking tab portion.

A single piece container made of cardboard, paperboard or other flexible sheet material which provides improved strength properties, but without the need to laminate layers of sheet material together by having an outer shell comprising sidewall panels (3, 5, 7, 9) and a set of inner sidewall panels (11, 13, 15, 17) connected to the outer shell at foldlines. The set of inner sidewall panels includes a first inner sidewall panel in facing relationship with the inner surface of a first outer shell sidewall panel and integrally connected to one of the outer shell sidewall panels along a foldline, and a first set of further inner sidewall panels integrally connected to the first inner sidewall panel along a foldline, the sidewall panels of the set of further inner sidewall panels being hingedly connected to one another about respective foldlines. The set of inner sidewall panels also includes a second set of further inner sidewall panels integrally connected to the first inner sidewall panel along a foldline, the sidewall panels of the second set of further inner sidewall panels being hingedly connected to one another about respective foldlines.

A single piece container (200) made from cardboard, paperboard or other lightweight foldable sheet material is provided. The container (200) includes an outer shell and an inner shell. The outer shell has first and second ends (202, 204), and includes a plurality of outer shell sidewall panels (3, 5, 7, 9) hingedly connected to one other about respective outer shell sidewall foldlines. The outer shell sidewall panels (3, 5, 7, 9) extend between the first and second ends (202, 204) of the outer shell. At least the second end of the outer shell is a closed end. The inner shell includes a plurality of inner shell sidewall panels hingedly connected to one other about respective inner shell sidewall foldlines. The inner shell is integrally connected to the outer shell along a foldline. Each one of the inner shell sidewall panels is in face-to-face contact with the inner surface of a respective one of the outer shell sidewall panels (3, 5, 7, 9).

A blank for forming a tamper evident container includes a plurality of panels connected together at fold lines configured for extending at least partially around an interior space, including a first side panel, a top panel, a second side panel and a bottom panel. A bottom flap is foldably connected to an edge of the bottom panel on the first end of the blank. A top flap is foldably connected to an edge of the top panel on the first end of the blank. The bottom flap includes a major flap and a minor flap, the major flap connecting between the bottom panel and the minor flap. The top flap includes a catch point feature and wherein the minor flap includes a trap aperture configured to catch the catch point feature of the top flap when opening a container constructed from the blank to provide a tamper evident access feature.

A tamper-evident container (1) including: a store (2) for housing at least one product, a closure system (7) placed at a passage opening (5) of the store (2) and configured for obstructing said passage opening to define a closed condition of the container (1). The store (2) has at least one glued portion at which a layer (40) made of heat-sensitive material is arranged, configured for irreversibly varying, following a heating of said layer (40), an optical and/or physical property of the same layer to provide evidence of an attempted tampering of the container (1).

Unitary blank for forming a container having a body portion with a plurality of fold lines and a cover portion. The body portion with a plurality of fold lines define a plurality of body wall portions, and each body wall portion has an upper edge. A first body wall portion includes a closure tab extending from the upper edge of the first body wall portion. The closure tab includes a closure tab flap portion and a closure tab base portion. The cover portion extends from the upper edge of a second body wall portion. The cover portion includes a cover portion flap score line extending along an upper edge of the cover portion and a release flap. A food container having a body portion and a cover portion is also provided.

A tray comprises a foldable sheet including: a bottom having a first sector with a folding line that defines a first joining zone, and a second sector joined to the first sector in the first joining zone; end walls each having an interior surface; support surfaces each extending from an end wall, where the support surfaces are oriented to support the weight of another stacked tray; first flaps each extending from a support surface, where each of the first flaps is folded towards an interior of the tray and having a surface facing and separated from the interior surface of an end wall; side walls; and a second flap extending from a side wall. The second flap is placeable a first position on a side wall for reinforcement and in a second position substantially perpendicular to the side walls to serve as a lid.

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

A box can include a body portion at least partially defining a cavity, the body portion defining a top body end and a bottom body end, the body portion including a plurality of panels, the top body end defining an opening to the cavity; a telescoping panel including an upper telescoping subpanel and a lower telescoping subpanel, the lower telescoping subpanel coupled to the body portion by a top hinge, the upper telescoping subpanel coupled to the lower telescoping subpanel by a telescoping hinge, the telescoping panel defining a locking tab disposed opposite from the top hinge, the lower telescoping subpanel extending into the cavity and positioned in facing engagement with a first panel of the plurality of panels, the upper telescoping subpanel extending across the cavity from the first panel to a second panel of the plurality of panels, the second panel positioned opposite from the first panel.
