Coffee Cup Lid, Sweetheart LT-510
notes: label: Description
content: This is a Sweetheart LT-510 pinch type coffee lid. Pinch type lids are a variation of the peel type, but the motion for removing a piece is the result of a specifically placed pinch to tear away a perforated piece of plastic. The lid is covered by patent number 4,518,096 assigned to Maryland Cup Corporation on May 12, 1983. The patent covered a lid with “a tear-away section removable by initially squeezing the lid and subsequently lifting and pulling at the point of squeeze to permit beverages to be consumed from the container. . .without removing the lid therefrom.”

content: Architects and collectors Louise Harpman and Scott Specht donated 56 plastic cup lids to the National Museum of American History in 2012. Their donation is a sample from their much larger collection of “independently patented drink-through plastic cup lids,” which they began in 1984 and discussed in a 2005 essay, “Inventory / Peel, Pucker, Pinch, Puncture,” in Cabinet Magazine: http://www.cabinetmagazine.org/issues/19/harpman.php. The collectors’ categorization scheme reflects the primary way the lid design functions, which helps differentiate between the varieties and styles of lids.
label: Description
content: Plastic, disposable coffee cup lids and other single-use food packages reinforce the social acceptability of eating and drinking on the go in the United States and reflect increasing expectation for convenience products. Cup lids are also examples of how humble, and even disposable, objects are sometimes the result of meticulous engineering. Patents for lid innovations describe peel-back tabs and the pucker-type shapes that make room for mouths and noses, and describe the nuances of “heat retention,” “mouth comfort,” “splash reduction,” “friction fit,” and “one-handed activation.”
