A foldable sealing container is provided with cuts, creases, adhesion of some elements, and a planar collapsed position to permit rapid reconfiguration to an expanded position. A plurality of catching mechanisms comprises friction tabs partially folded along friction tab creases to engage friction tab edges with side panels and hold the bottom side panels substantially perpendicular relative to the bottom panel. The plurality of catching mechanisms holds bottom side panels in a substantially upright position to form leak-proof seals at the lower corners. Engagement of the friction tab catching mechanisms provides enhanced leak resistance, improving storage and transportation of liquids and liquid-containing foods.

A method is disclosed for forming a covered cardboard container from a single template. The template is configured such that, when side panels are lifted off the top face of the template, a front panel and rear panel are lifted together with the side panels. The container is formed when the two side panels, the front panel and the rear panel are all in a substantially vertical position.

After the container is formed it is filled with product, such as apples, pears, avocados, and the like. The container has two top panels that are folded over the product and adhered to one another to form a lid. Score lines in the top panel allow the container to accommodate products of varying size.

A foldable carton is provided. The carton includes a bottom panel, a front panel, a rear panel, end panels, each foldably connected to the edges of the bottom panel. The carton further includes front end flap panels connected to the lateral ends of the front panel and rear end flap panels connected to the lateral ends of the rear panel. Each front end flap panel includes a connecting end section and a triangular fold flap connected to the connected end section. The triangular fold flap is connected to a side edge of the adjacent end panel by a hinged fold line. The connecting end section is secured to the front panel in an overlying arrangement and the triangular fold flap is configured to about the hinged fold line to allow the front panel to freely move between a fully upright position and a partially upright position.

A panel interlocking arrangement for securing a pair of panels together comprising: first and second panels for placement in an overlapping position. The first and second panels are disposed at least in part in a face-contacting arrangement. A pair of locking elements are provided for locking engagement with each other to secure the first and second panels in the overlapping position. The pair of locking elements comprises a male locking element and female locking element. The female locking element is formed in the second panel and the male locking element is connected to the first panel.

A reusable foldable box is disclosed that has a first flat configuration and a second three dimensional configuration. The box consists of a first set and a set of panels that are assembled to form the foldable box. The first set of panels includes at least six panels that are foldably coupled in a predefined sequence. The first set includes a top panel, bottom panel, a pair of side panels, a lip panel and a securing panel. The first set of panels forms a single piece construction to which the side panels of the second set of panels are coupled with triangular inward connectors.

A tray (100) including first and second compartment portions (20, 40) each having a bottom panel (22, 42), a first side panel (24, 44) foldably connected to a first side edge (22a, 42a) of the bottom panel, a second side panel (26, 46) foldably connected to a second side edge (22b, 42b) of the bottom panel, a front panel (28, 48) foldably connected to a front edge (22c, 42c) of the bottom panel and a rear panel (30, 50) foldably connected to a rear edge (22d, 42d) of the bottom panel, wherein a side edge of the front panel (28a, 48a) and a front edge (26a, 46a) of the second side panel are connected to one another by a front bi-fold corner web panel (32a, 32b, 42a, 42b) and a side edge (30a, 40a) of the rear panel and a rear edge (26b, 46b) of the second side panel are connected to one another by a rear bi-fold corner web panel (34a, 34b, 44a, 44b).

A collapsible, reusable shipping box has an initial flat configuration, a box configuration and a mailer configuration. In the mailer configuration, the mailer can be returned.

The plastic foldable storage device is made from hollow and comb-shaped plastic plates, and includes a rectangular base plate, two first side plates extended respectively from two shorter edges of the base plate, and two second side plates extended respectively from two longer edges of the base plate. The first and second side plates are edge-to-edge joined by joining strips. Each first side plate has two folding lines along its inner surface. The first and second side plates, through the joining strips and the folding lines, are selectively folded into a level positon resting on the base plate or unfolded into an upright position to form a storage space with the base plate. The plastic foldable storage device therefore provides convenient use and storage, while offering additional advantages such as repeated usage, moisture proof, and robustness.

A food container includes a bottom panel and sidewalls pivotally connected to the bottom panel. A lid is pivotally connected to at least one sidewall to open and close the food container. A divider panel having at least one slot is inserted into any one of a plurality of slots in a spacer panel to create an adjustable compartment arrangement inside an internal cavity of the food container. The divider panel includes a groove that provides a recess between the divider panel and a sidewall of the food container that can accommodate a lip of the lid.
