Abstract

See full text

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.
