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.

1. An array of trays comprising a plurality of trays coupled in edge to edge relation and adapted to rest on a substantially flat surface, and wherein each tray has a containment space defined by a tray floor and a continuous peripheral ridge extending upwardly from the tray floor, the ridge having 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 such that a void space is created between the inner and outer sidewalls, and wherein the trays are coupled by a connector member comprising a base plate adapted to rest on the flat surface, and at least two lobes extending upward from the base plate, one lobe extending into the void space on one tray, and one lobe extending into the void space on the adjacent tray such that outer surfaces of the lobes are adjacent to the inner and outer sidewalls and thereby support the peripheral ridge wherein the void space of each tray is configured to receive the peripheral ridge of a like tray so that multiple like tray so that multiple like trays can be stacked compactly on top of each other.2. An array of trays as in claim 1 in which the outer sidewall of each tray extends downward and outward from the upper edge of the ridge to enhance stacking compactly.3. An array of trays as in claim 1 comprising a grip by which the array can be pulled.4. An array of trays as in claim 3 in which the grip comprises apertures in the outer sidewall of at least one tray adapted to receive prongs of a puffing handle.5. An array of trays as in claim 1 further comprising an absorbent pad adapted to cover a substantial portion of the tray floor, and means to retain the absorbent pad in position on the tray floor.6. An array of trays as in claim 5 wherein the means to retain the absorbent pad in position on the tray floor comprises a spring member, and wherein the spring member engages spring apertures in opposite outer sidewalls of the tray.7. An array of trays as in claim 1 wherein the outer sidewall extends outwards such that the lobe can disengage from the void space when a tray is subjected to a sufficient lateral force.8. An array of trays as in claim 1 wherein at least one lobe is attached to a tray defining the void occupied by the at least one lobe.9. An array of trays as in claim 1 in which the connector member provides for a coupling of trays in which one tray may extend beyond the end of another tray.10. An array of trays as in claim 1 wherein at least one lobe defines lobe apertures in an outer sidewall thereof, and wherein the lobe apertures are adapted to receive prongs of a pulling handle.11. An array of trays as in claim 1 further comprising a filler cap adapted to engage adjacent trays and to cover a gap between the upper edge of the peripheral ridge of one tray and the upper edge of the peripheral ridge of an adjacent tray.12. An array of trays as in claim 1 further comprising a filler cap adapted to engage adjacent trays and to cover a gap between the upper edge of the peripheral ridge of one tray and the upper edge of the peripheral ridge of an adjacent tray.13. An array of trays as in claim 12 wherein the filler cap comprises: a) a cap member extending laterally beyond the upper edge of the peripheral ridge of each adjacent tray; b) a lock member extending downward from substantially a center of the cap member and adapted to engage a bottom edge of outer sidewalls of each adjacent tray.14. An array of trays as in claim 13 wherein the lock member comprises a pair of resilient legs extending downward from a bottom end thereof the legs separated by an empty space, the legs each comprising an outward extending tab adapted to engage the bottom edge of outer sidewalls of an adjacent tray.15. An array of trays as in claim 13 wherein the lock member comprises a pair of outward extending tabs at a bottom end thereof, the outward extending tabs adapted to engage the bottom edge of outer sidewalls of an adjacent tray.16. An array of trays as in claim 13 wherein the lock member further comprises a resilient centering member extending outward on each side of a midpoint of the lock member and bearing against the outer sidewall of each adjacent tray.
