An apparatus and method utilizes a forming machine which includes a mandrel and forming plate each shaped to conform the paperboard and/or corrugated material blank passing through the mandrel into the desired configuration for a leak-proof tray. The blank includes a layer of a suitable paperboard and/or corrugated material, and a layer of leak-proof plastic or paper material disposed over one side of the corrugated material. The corrugated material includes cutouts at each corner of the blank that enable the sides and ends of the blank to be folded relative to one another. The paper material continuously overlaps the surface of the corrugated layer and these cutouts to provide a continuous leak-proof barrier layer within the formed tray and at the corners of the blank when folded to form the tray, as the paper material is folded over itself to form a bellows corner in the tray.

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, each corner panel having an edge connected to a respective one of the first and second side panels and having an edge connected to the inner end panel. First and second locking tabs are defined in the outer end panel, each locking tab being defined by a lateral separation line located longitudinally inward from an outer longitudinal edge of the outer end panel and extending laterally to define a free tab end.

A single blank for forming a box, the blank comprising a first panel, a second panel, a third panel and a fourth panel. The first panel is foldably connected to a folding support structure that is foldable and insertable inside the box. The folding support structure comprises a first inner flap which is connected to the first panel along a first inner flap fold line, a second inner flap which is connected to the first inner flap along a first inner flap second fold line, a first integral holding panel which is connected to the second inner flap along a first edge fold line, and a second integral holding panel which is foldably connected to the first integral holding panel along a second integral holding panel fold line.

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 box can include a container portion, the container portion defining a top end and a bottom end, the container portion defining a cavity, the container portion including a main panel; and a side panel including a first side subpanel and a second side subpanel, the first side subpanel hingedly coupled to the main panel; and a dividing portion disposed within the cavity, the dividing portion defining a plurality of cells within the cavity, the dividing portion including a first dividing wing coupled to the first side subpanel; and a second dividing wing coupled to the second side subpanel.

A box includes a container portion, the container portion defining a top end and a bottom end, the container portion defining a cavity; a telescoping portion attached to the top end of the container portion, the telescoping portion selectively reconfigurable about and between a retracted configuration and an extended configuration, a portion of the telescoping portion being positioned within the cavity in the retracted configuration, the telescoping portion disposed external to the cavity in the extended configuration; and a dividing portion disposed within the cavity, the dividing portion defining a plurality of cells within the cavity.
