Provided is a folding packaging cooler box convertible from a box mode to an unfolding mode or vice versa, comprising: a box portion having a bottom portion, sidewall portions and joint portions configured to connect with one another and to form a single plane in the unfolding mode; and a cooling reinforcing portion configured to be inserted to the inside of the box and to form a hexahedron shape together with said box portion when said box portion is converted into the box mode, wherein said cooling reinforcing portion comprises a reinforcing bottom portion configured to form a lower surface and to face the bottom portion of the said box portion upon conversion into the box mode; reinforcing sidewall portions configured to connect with the said reinforcing bottom portion and to face the sidewall portions of said box portion; and reinforcing joint portions configured to join said reinforcing sidewall portions, to be folded to face itself and to be in close contact with the reinforcing sidewall portions, upon conversion into the box mode, and wherein said reinforcing bottom portion, said reinforcing sidewall portions and reinforcing joint portions form a single plane in the unfolding mode.

A collapsible and reusable food storage container is formed from a single, foldable sheet having a receptacle portion and a lid portion. The foldable sheet is formed from a plurality of planar panels positioned adjacent to one another, with a foldable seam spanning an offset formed between sets of the adjacent planar panels. In use, the foldable sheet may be repeatedly transitioned between a collapsed configuration in which the foldable sheet is folded about the foldable seam into a flat packet and an assembled configuration in which the foldable sheet is unfolded into a receptacle and an attached lid for securely storing a portion of food. The planar panels may be formed of polypropylene, while the foldable seam may be formed of silicone that is overlaid into the offset between adjacent panels and sonically welded to the edges of the adjacent planar panels. Other embodiments are also disclosed.

A method for assembling an insulated box assembly includes positioning an inner corrugated portion and an insulated layer between a plurality of side portions of an outer corrugated portion, the inner corrugated portion including a plurality of side panels hingedly coupled together, the insulated layer extending around the plurality of side panels, the insulated layer coupled to the inner corrugated portion, the insulated layer positioned between the inner corrugated portion and the outer corrugated portion, the insulated layer including at least one insulation batt, the plurality of side panels defining a top end and a bottom end of the inner corrugated portion, a bottom panel being positioned at the bottom end below the insulated layer, the plurality of side panels and the bottom panel at least partially defining a cavity, an opening to the cavity being defined at the top end, and enclosing the cavity with a top.

A container for supporting a food product includes a tray and a liner. The tray includes a plurality of panels at least extending at least partially around an interior of the tray, the plurality of panels comprising a bottom panel, at least one side panel, at least one end panel, and at least one corner panel. The liner includes a central panel and at least one marginal panel each foldably connected to a gusset. The container is reconfigurable between a first configuration in which the at least one end panel and the at least one corner panel are in generally planar overlying relation with the respective bottom panel and the at least one side panel, with the liner positioned therebetween and with the gusset in a folded arrangement, and a second configuration in which the at least one side panel, the at least one end panel, and the at least one corner panel are generally upright relative to the bottom panel with the gusset in an expanded arrangement.

A tray for containing a product includes a base, a lateral wall emerging from the base to define a containing seat adapted to receive the product. The lateral wall comprises at least one movable portion configurable between a first stable position, wherein the movable portion is placed in continuity with respect to the lateral wall, and a second stable position, wherein the movable portion protrudes from the lateral wall and defines an access passing through the lateral wall itself. Moreover, the present invention refers to a process and an associated apparatus of making said tray. Further, the present invention refers to a vacuum package using the above described tray and to a plastic film sealingly applied on the tray and closing the access, and also to a process and a packaging apparatus for making said package.

An insulated box assembly includes an insulated box, the insulated box including a box, the box including a bottom panel and a side panel, the side panel attached to the bottom panel, the box defining a box cavity; and an insulated panel attached to the side panel, the insulated panel including an insulation batt and a sheet, the insulation batt enclosed between the side panel and the sheet; and an insulated cavity panel, the insulated cavity panel disposed within the box cavity, the insulated cavity panel including a cavity sheet and a cavity insulation batt, the cavity sheet encapsulating the cavity insulation batt.

A method for insulating a box includes positioning an insulated panel adjacent to a side panel of the box, the insulated panel including an insulation batt and a sheet, the insulated panel defining a border extending around a perimeter of the insulation batt; and attaching a seam of the border to a portion of a perimeter area of the side panel.

A container for a food product generally includes a tray and a cover attached to the tray by ultrasonic bonds. The tray includes a bottom having a perimeter and a sidewall extending along the perimeter of the bottom to form a cavity sized to receive the food product. The sidewall defines an opening for the food product to be placed into the cavity. The tray also includes a flange extending from an edge of the sidewall and around the opening. The flange has a single layer first area with a first thickness and a second area comprised of at least two layers with a second thickness. The second thickness is at least twice as thick as the first thickness. The ultrasonic bonds extend along the entire sidewall of the container to form a continuous, hermetic seal between the cover and the tray around the opening.

Provided is a packaging cooler box for delivery, comprising a bottom portion to form a lower surface upon conversion into a box mode, a plurality of sidewall portions configured to connect with the bottom portion, a lid portion configured to connect with one of the sidewall portions, and to face said bottom portion upon conversion into the box mode, a crease portion formed along the edge of the bottom portion so that the sidewall portions can stand upright, joint portions configured to join said sidewall portions, to be folded to face itself and to be in close contact with the sidewall portions, upon conversion into the box mode, and easy adhesive portions provided in said joint portions and sidewall portions to maintain the box shape upon conversion into the box mode from a single plane consisting of said bottom portion, sidewall portions, said lid portion and joint portions.
