For some of us, Tupperware parties hold a special kind of nostalgia. They were a time when sales representatives flung plastic containers across a room to prove the strength of the patented “burping” seal, party-goers would leave with storage products stacked high in the backseats of their cars and the more containers party hosts sold, the more kitchen gadgets they would gather in their cabinets. But the days of Tupperware – and the accompanying parties – may be about to end. Shares in the Massachusetts firm, which became famous in the 1950s and 1960s, crashed by almost 50% this week after it told investors there was “substantial doubt about the company’s ability to continue as a going concern”.
