Abstract
A leak-resistant plastic container and closure are disclosed, where the container has an open end, an inner periphery, an outer periphery, and a container flange extending around the inner periphery at the open end. The closure has a generally planar and circular inner lid, a spring extending around an outer circumference of the inner lid, an arcuate flange receptacle extending around an outer circumference of the closure at a circumference outside the spring, where the flange receptacle has an inner surface and an outer surface, a secondary sealing bead, positioned on the inner surface of the flange receptacle, and a primary sealing bead, positioned on an outer surface of the flange receptacle and opposite the secondary sealing bead, where the spring exerts a sealing pressure against the container flange when the closure is placed on the open end of the container.
