Karo Syrup Can Lid Cover with Lift Tab - Vintage Metal

Vintage metal lid for a Karo syrup can, with a raised lift tab marked LIFT. Lid face reads "FOR Karo CANS ONLY" and what looks like "PATENT" and a date, partly worn. Silver-tone metal with age wear, scratches and dark spotting on the surface. Small round diameter, roughly the size of a syrup can top. Appears to be an early-to-mid 20th century piece, but age is not confirmed. Please check: exact era and date, whether the patent number is legible, whether the lid fits a can, and any dents or rust underneath. • Item: A specialty vintage metal snap-on or slip-on lid/pouring spout designed specifically for classic steel cans of Karo Syrup. • Function: In the mid-20th century, corn syrup often came in sealed metal cans that required punching or a special reclosable pouring lid to dispense the thick syrup cleanly without making a sticky mess. • Markings: It features an embossed thumb-lever or arm marked "LIFT" to open and close the spout, and text designating it for use on Karo syrup cans (often associated with mid-century kitchen gadgets and vintage patent designs like US Patent 1987055).
