The Tri-Seal Gasketless Openhead Plastic Pail Cover from BWAY Corporation (Atlanta, GA) produces a watertight/airtight seal without a gasket. Ideal for foods, paints, adhesives, lubricants, building products, consumer products, and more, it can be used anywhere a typical gasketed cover is used. No special capping equipment is needed. The cover works with standard rigid-plastic pails and is a drop-in replacement for a standard gasketed cover on most filling lines, with only minor adjustments to existing capping equipment. The patented design of the molded Tri-Seal Cover comprises a primary inner plug “cork” seal that is unaffected by changing top loads, a secondary top “flap” seal that engages the lip of the pail, and a tertiary outer “stretch” seal for added security.
