Tupperware warns it could go bust without emergency funding

Shares in US firm famed for its plastic containers have fallen almost 50% this week amid fears for its future

Tupperware, the 77-year-old company famed for its airtight food containers, has warned it could go bust if it cannot raise emergency funds to stay afloat.

Shares in the US company, which became famous in the 1950s and 1960s when agents held “Tupperware parties” to sell the plastic containers to friends and families, crashed almost 50% this week after a warning to investors that there was “substantial doubt about the company’s ability to continue as a going concern”.
