Princeton University engineer Michael Tseng invented the Plate Topper, a product that transforms plates into storage containers. You simply put a plate topper on top of a plate, grab the handle and then press down. It creates an airtight food storage container without having to find the elusive Tupperware lid. Tseng pitched his business on Shark Tank and received many offers but he had difficulty negotiating. In the end, he made a deal with Lori Greiner but it fell through.
Greiner was asked about Plate Topper during an AMA session on Reddit: She wrote: “Plate topper guy was stubborn and didn't listen to anything anyone had to say. Same in the Tank. Can't go forward with that.” She added, “”it was such a good product, but such bad entrepreneurship though! Watching that episode made me want to tear my hair out!” Plate Topper did make a deal with Walmart but the product is no longer available there, nor it available on the Plate Topper website. Plate Topper can still be found on Amazon.
