Vintage Tupperware Servalier Seal Lid

This item is a circular, sun-faded maroon or burgundy plastic lid, specifically identified as a Tupperware Servalier seal. The lid features the iconic accordion-style 'sunburst' or 'starburst' architectural design on the top (visible as concentric ridges) and an indentation in the center intended for a 'one-touch' seal mechanism. The underside, as shown, contains raised embossed text including the 'TUPPERWARE' brand logo, the manufacturing location in 'ORLANDO, FLA. U.S.A.', and various safety instructions. The material is a durable heavy-gauge polyethylene plastic characteristic of Tupperware production from the late 1960s to high mid-century periods. The condition shows significant signs of age and utility; there is notable surface scuffing, white chalky oxidation or 'blooming' typically found on older plastics, and residue around the center seal area. There are no visible cracks or melted edges, indicating it remains functional, though it possesses a heavy patina of use. These lids were designed for airtight storage and were a staple of American kitchenware during the mid-to-late 20th century.
