摘要:
Method and apparatus for forming a hinge in a thermoformed container, such as an egg carton, and the resulting container. The hinge is formed in the mold, by severing a thermoformed container along the length of a hinge line, with the exception of plurality of spaced connecting membranes that are not severed. The alternating severed portions and connecting membranes are referred to herein as a notched hinge connection. The width, depth, and location of the connecting membranes can be adjusted so the hinge area is strong enough to withstand multiple openings during use.

Plastic egg cartons having mating cell and lid posts for improved egg protection. The carton has a base tray and hinged lid, the tray including a plurality of cells for receiving individual eggs, and the tray having a plurality of cell posts each formed at an intersection of four adjacent cells as an extension of the sidewalls of the four adjacent cells. Preferable, each cell post has four generally planar ramp surfaces, one disposed respectively on each of the four sidewall extensions. The lid has a plurality of lid posts for mating with the cell posts when the lid is in a closed position.

Packing tray for protecting fragile and perishable food items, such as pears, which allows fruit items of varying dimensions and weights to be held securely in each pocket, and which allows a plurality of stacked trays and fruit to be packaged in boxes (e.g., standard carton sizes). The tray is a plastic foam sheet having a top wall and a plurality of recessed cell pockets, each cell pocket having a relatively thinner cell sidewall with expandable (accordion-like) flutes, and a relatively thicker bottom wall also with expandable flutes. This construction allows the cell bottoms in adjacent pockets and in adjacent trays of the stack to move relative to one another to accommodate various sizes and weights of fruit while still protecting the fruit from damage.
