Abstract
Abstract A snap cap apparatus is provided for sealing individual or a plurality of containers having necked openings. The snap cap apparatus comprises one or more caps, each cap having a pliable cover, the cover supporting one or a plurality of caps for sealing corresponding containers having necked openings. The snap caps providing a chamber and concentrically positioned within the chamber are stopper elements with a base connected to the thin pliable cover. The stopper elements terminating in an exposed end portion which is tapered to a smaller dimension than the base, the exposed end portion being positioned proximal to the open end of the chamber of the cap, the cap and stopper element combining to define an open ring portion for receiving container opening neck portions.
