Abstract:
1. A method of providing a close fit between a molded container and a molded overcap, where the overcap has a smaller amount of tolerance in the molding process than does the container, the method comprising the steps of: (a) providing a container, such that said container has an opening surrounded by a rim, said rim having an upper portion that is rounded and a lower portion that is flat in cross-section, wherein said container comprises a nominal outer diameter at a largest circumference of said rim of OD (b) providing a snap-on overcap to removably snap over said rim of said container, wherein a base of said overcap is sized to cover said opening, said overcap further comprising a flange with an outer surface extending essentially perpendicularly from said base, an inner surface of said flange comprising an essentially perpendicular portion extending from the base, a circumferential ridge adjacent the essentially perpendicular portion, said circumferential ridge having a peak defining a flattened upper and lower faces, said flattened upper face being configured to seat against said rim flat lower portion such that the only contact between said rim and said flange takes place between said flattened upper face and said rim flat lower portion, wherein further said flattened upper face comprises an adjacent upper surface, wherein said adjacent upper surface and said flattened lower face angle away from said container, said overcap having a manufacturing tolerance of T
