Abstract
The combination of an injection-molded, snap-on cap and a blow-molded, plastic container are designed to act together to provide a seal that prevents a loss of freshness to the porous product stored within, regardless of variations in the manufacturing process. Instead of a rounded ridge on the container, the ridge has a flattened section on its lower half. On the inside of the snap-on cap, the ridge has two flat surfaces. A first flat surface is designed to fit snugly against the flat surface on the ridge of the container, even at the extreme range of small container/large cap. The design has been shown to dramatically reduce the absorption of moisture by an enclosed product, demonstrating that a desirable seal is formed.
