A tray has a containment space defined by a tray floor and a continuous peripheral ridge extending upwardly from the tray floor. The ridge has an inner sidewall extending inward and downward from an upper edge of the ridge and an outer sidewall extending downward from the upper edge of the ridge. Multiple trays are coupled together by a connector member having lobes that mate with the shell-like structure of the ridge, and provide additional strength to the peripheral ridge. The tray can be provided with a shell-like construction such that multiple trays can be stacked compactly one on top of the other.
