Here is a vintage, space age (obviously!) cocktail shaker marked Steri-lite and United Plastics Corporation. The rocket has a yellow top, a red body, and yellow base. The rocket base features four fins and is free standing. The shaker measures 9” in height and has a hinged cap at its capsule top that is used to pour out your drinks.
eBay item 191487719506 sold January 26, 2015 at 3:07PM (United States). Six bidders placed 15 bids on the cocktail shaker. The shaker sold for $67.66 plus $6.00 shipping.
The rocket is marked on the bottom: Steri-lite (in script), around the base: FITCHBURG MASS / USA UNITED / PLASTIC CORP and vertically PAT PEND and 2. The numeral 2 is presumably a mold number.
The Steri-lite mark refers to the Sterilite Corporation, which was founded in 1939 as a partnership between Saul and Edward Stone and Earl Tupper (yes, the Tupper of Tupperware fame) and at the time was located in Fitchburg, Massachusetts. United Plastics Corporation has been a leader in the manufacturing of quality plastic products since 1946.
