The owners of gourmet lunchbox makers UPBox are hopeful of getting the business back on track after the company ceased trading last Thursday following the withdrawal of one of its two backers.

Founders Ines and Nick Alfille will meet both backers this week in a bid to restructure the company and come up with a re-opening date. Launched in 2008, the company has four London outlets, two in stations Clapham Junction and Vauxhall and two in the City, and had been looking at premises in Brighton.

Until last week, UPBox made and shipped up to 200 lunchboxes a day from premises under London's Westway. Its menus, which changed weekly, were influenced by 12 national cuisines, with ingredients sourced from local suppliers. Each lunchbox retailed at £6.50 and the company was in the process of developing a smaller, cheaper version.
