A foldable case and method of making same are disclosed. The foldable case is collapsible between a closed position and an open position without needing to re-fold the sheet of material. The foldable case is made of a sheet of material. The sheet of material has a central portion, opposing first and second portions, and opposing third and fourth portions. First and second portions adjoin a length of respective top and bottom edges of the central portion. Third and fourth portions adjoin a length of respective left and right edges of central portion. A number of folding lines are provided on the sheet of material. The foldable case can be made by folding along the folding lines and adhering first and second portions to the third and fourth portions so as to form a case in the folded configuration.

A unitary disposable beverage container sleeve that can also be used as a coaster and that can be comprised of (optionally recyclable) cardstock for economically imprinting with advertising logos or slogans. The upper body vertical rectangular edges are connected to form sides of the sleeve and a gusset extends across the diameter at the lower edge to form the base of the sleeve. The gusset has a hinge that opens and closes the sleeve. Arched grooves positioned at that lower edge above the gusset where the gusset attaches to opposing sides of the sleeve allows flex in the sleeve and affords a level base.

A reusable shipping box system and methods are provided. The reusable shipping box system includes a shipping box including a rectangular sheet of material including a first planer surface and a second planer surface. The first planer surface can include a first herringbone pattern of half cut and full cut incisions and the second planer surface can include a second herringbone pattern which is different from the first herringbone pattern. The rectangular sheet of material can be capable of collapsing into an elongated shaped parcel by way of the first and second herringbone patterns of half cut and full cut incisions. A shipping sleeve can define a cross-sectional shape and sized to be capable of sliding over the collapsed shipping box and securely hold the shipping box in the collapsed shape.

A box is made by folding a sheet of material. Preferably, the box is formed by applying adhesive and folding using a machine, and a waterproof or water-resistant coating is applied to the sheet of material so that the box is configured for use as a cooler. The box includes: a storage portion, including a bottom panel, first and second end panels, and first and second side panels; four corner panels; and first and second top panels. The top panels include openings that register when the box is assembled and in a closed configuration to define an opening to be used as a handhold for gripping the box. Reinforcing panels of one of the top panels includes flaps located on an interior of the box that cover the handhold opening. The box further preferably includes a locking tab and locking panel for latching closed the top panels of the box.

A box can include a first side panel; a second side panel positioned perpendicular to the first side panel; a top panel joined to the first side panel; and a handle assembly, the handle assembly including a handle portion attached the top panel, the handle portion including a tab at a side end of the handle portion, and a locking panel attached to the second side panel, the locking panel defining a cut pattern, the cut pattern defining a space therewithin, the cut pattern defining a top edge and an inner flap, the top edge of the cut pattern being a fold line formed by folding the inner flap up above the top edge; and wherein the tab is received by the space.

A container device that has an outer shell with an opening that is sealed by a closure mechanism. The closure mechanism can include magnetic strips that are configured to partially or wholly seal the opening.

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.

The invention provides a foldable box connection structure, a foldable box and a method of using the same. The foldable box connection structure comprises a first side plate, a second side plate, a first hinge, a first top plate, a seam cover plate and a positioning plate. The first hinge is used to connect the first top plate and the second side plate. The seam cover plate can be folded to cover the first hinge, and the seam cover plate and the positioning plate are configured to secure the first hinge. The foldable box includes the above-mentioned connection structure. In the present invention, the first top plate is hooked by the first hinge and the seam cover plate, and a second top plate is hooked by a third hinge, so that the foldable box has a fixed structure.
