A recently granted patent (Publication Number: US11884462B2) discloses a tray made of lightweight foldable sheet material, such as cardboard or paperboard, designed with one or more pockets for product storage. The tray consists of a top sheet with openings aligned with bottom sheet openings, allowing for the formation of pockets. Each pocket is constructed with top and bottom sheet flaps that fold to create side walls and base walls, with the top sheet flaps being bonded to the bottom sheet flaps within each pocket. Additionally, the tray can have multiple pockets with varying depths, and the top and bottom sheets are bonded together at their peripheral flanges.

Furthermore, the patent details a method for manufacturing the tray, involving the use of male and female forming tools to fold the bottom and top sheet flaps into cavities, securing them together with adhesive. This method ensures the precise assembly of the tray structure, with the option to apply adhesive to selected areas before engagement of the top and bottom sheets. The design variations in the tray, such as tapered pockets and different configurations of flaps, offer versatility in product storage and manufacturing processes, making it a unique and efficient solution for packaging needs.
