A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels forming gussets connected to a respective one of the first and second side panels and connected to the inner end panel. An adhesive area is located on one side of the blank and comprises at least a portion on each of the outer end panel and the inner end panel. The adhesive area adheres the gussets to the inner end panel and to the outer end panel.

An enclosable and stackable container comprising a tray and lid is provided with structural elements to permit rapid covering and uncovering of the tray, efficient stacking of containers, and safe transportation. At least one catching mechanism may be engaged quickly to securely cover the tray and its food contents and disengaged quickly to uncover the tray and its food contents, improving food hygiene practices. Foldable flange flaps enhance stacking strength to permit safe transportation of stacked containers and their food contents.

A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels at opposing lateral edges of the blank, and opposing end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel, an outer end panel hingedly connected to the inner end panel at hinge portions, and first and second corner panels, each corner panel forming a gusset between one of the side panels and the inner end panel, each gusset including a notch area for receiving one of the hinge portions. First and second locking tabs are defined in the outer end panel. The outer end panel can be folded over the inner end panel to position the hinge portions in the notch areas, and the locking tabs can be positioned between the gussets and the inner end panel.

The following summary concerns the development of a folded leak-proof container (46) that consists of one piece of fiberboard or cardboard (1) containing slits and folds that produce the center panel (3), the top panel (4), the bottom panel (5), the side panels (6 and 7), and the end panels (8-15), the latter of which contain lengthwise slits (18-25) to be folded in order to form the side handles of the container (46); the container may also include a top handle (2). The main function of the container (46) is to keep cool, transport, and cool items that must be refrigerated; it can do so through the addition of ice or any coolant compatible with the material used to manufacture the container.

A locking arrangement for a container that has a lid pivotally attached with a base includes a flap that is pivotally attached at a first end thereof to the lid at a peripheral edge of the lid. The flap has a tab projecting laterally away from a second end of the flap. A frangible portion of the lid is defined by a perforation that terminates to encompass the first end of the flap. A slot is formed through an upwardly-projecting peripheral wall of a base of the container. As such, with the lid of the container moving towards a closed position, and with the tab in a folded position, the flap and tab are inserted through the slot of the peripheral wall of the base, thereafter as the tab clears the slot the resilient material urges the tab into an expanded position to lock the container.

The present application relates to a folded packaging container structure, and a bottom folding-sealing device and process, including: a folded packaging body, which forms a cavity for accommodating a object after being folded; an upper opening, which is located on the folded packaging body, at which a cap is provided at least after the cavity is loaded with the object; a folded part A and a folded part B, which are folded and contacted with each other; a front surface of the folded part A and a front surface of the folded part B are provided as corresponding front surfaces of the folded packaging body and are located between the bottom part and the upper opening; at least a first side surface and a second side surface located between the bottom part and the upper opening are provided between the front surfaces.

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 carton. The carton may include a floor panel; a plurality of side panels extending about a periphery of the floor panel, a front tab formed at an upper edge of a front side panel, upper side flaps extending from upper edges of a first end side panel and a second end side panel, and wherein each flap includes a side receiving slot; foldable corner gussets extending between adjacent side panels, wherein the floor panel, side panels, and foldable corner gussets are configurable to form a compartment region; a hingeable lid, including: a lid panel, a front edge flap, a side tab formed on each opposing side edge of the lid panel, and a front receiving slot formed in the front edge flap, wherein the lid panel is configured to cover the compartment region when in a closed position; and wherein the front tab of the front side panel is configured such that when the hingeable lid is in the closed position, the front tab aligns with the front receiving slot and is receivable therein and each side tab aligns with its respective side receiving slot and are receivable therein.

A leak proof container and a method of forming the container from a blank. The blank includes a bottom panel, first and second side panels connected to the bottom panel at opposing lateral edges, and first and second end portions located at opposing longitudinal ends of the blank. Each end portion includes an inner end panel connected to the bottom panel, an outer end panel connected to the inner end panel, and first and second corner panels forming gussets connected to a respective one of the first and second side panels and connected to the inner end panel. An adhesive area is located on one side of the blank and comprises at least a portion on each of the outer end panel and the inner end panel. The adhesive area adheres the gussets to the inner end panel and to the outer end panel.

A carton for holding one or more articles includes a plurality of panels extending at least partially around an interior of the carton, the plurality of panels including a front panel, a back panel, and at least one side panel. The carton also includes a plurality of end flaps foldably connected to respective panels of the plurality of panels and forming a closed top portion of the carton, the closed top portion of the carton is reconfigurable between a first configuration having a substantially flat profile and a second configuration forming a handle of the carton. The carton also includes locking features for engaging at least one other carton.
