A tray closure assembly (1) having an interconnected array (3) of compartments (4), a closure (20) in the form of a flexible sheet for the compartments being arranged so that the closure and the compartments form a series of sealed containers, and optionally so that each sealed container is frangible from the interconnected array so that a sealed container may be removed from the array, an openable flap (50) for overlying the closure, the flap being attached to the tray by attachment to the closure. The sealing closure offers two functions, one to form the seals for the compartments and secondly to hold a protective flap to the tray.
