Abstract
An end closure for reclosable packages which is adapted for manual placement over an appropriately sized open package, container or box to substantially enclose a food product therein. The end closure comprises a substantially rectangular resilient end wall having side walls extending down perpendicularly therefrom at each edge. A thin, flexible, pleated sheet overlays the end wall and two opposing side walls. The two sidewalls include expansion joints, and the pleat is substantially coincident with the expansion joints, permitting the end closure to open against a bias when manual pressure is appropriately exerted. The end closure, when held open, therefore fits easily over the package opening. When the manual pressure is released, the end closure closes, forming a tight fit with the sides of the package, effectively protecting the food product from the environment. An end closure in accordance with the disclosed invention may be employed in conjunction with a tear-strip package of substantially uniform cross-section to provide a space-efficient package with a reusable closure as the package is reduced in size.
