Leak-resistant tray and lid
A container includes a molded tray and a molded lid, both made of unitary fiber bodies. The tray includes at least one internal well and a perimeter engaging wall extending upward from a perimeter rim. The perimeter engaging wall includes an inner surface, an outer surface, and an uppermost surface. The lid includes a ceiling and defines a perimeter engaging receiver extending upward from a perimeter rim. The rim is defined by an inner wall, an outer wall, and an uppermost wall. The perimeter engaging wall is configured to be removably received in the perimeter engaging receiver.
1. A container comprising:
a molded fiber tray comprising:
a unitary fiber body defining at least one internal well, wherein the molded fiber body comprises a perimeter engaging wall extending upward from a perimeter rim of the molded fiber tray, the perimeter engaging wall comprising an inner surface, an outer surface, and an uppermost surface spanning the inner surface and the outer surface, and wherein the uppermost surface of the perimeter engaging wall at least partially defines a continuous groove that extends along the uppermost surface; and
a molded fiber lid comprising:
a unitary fiber body comprising at least one ceiling, and wherein the unitary fiber body defines a perimeter engaging receiver extending upward from a perimeter rim of the molded fiber lid, the perimeter engaging receiver at least partially defined by an inner wall, an outer wall, and an uppermost wall spanning the inner wall and the outer wall,
wherein the perimeter engaging wall is configured to be removably received in the perimeter engaging receiver,
wherein, when so received, the inner surface contacts the inner wall, the outer surface contacts the outer wall, and the uppermost surface contacts the uppermost wall,
wherein, when so received, the at least one internal well and the at least one ceiling define a substantially sealed internal volume, and
wherein the continuous groove and the uppermost wall define a small volume into which liquid that penetrates past sealing surfaces is contained to limit leakage and act as a pressure relief.
2. The container of claim 1 , wherein the unitary fiber body of the molded fiber tray further comprises at least one partition that subdivides the internal well into a plurality of wells, and wherein the unitary fiber body of the molded fiber lid defines at least one internal channel that subdivides the at least one ceiling into a plurality of ceilings,
wherein the at least one internal channel is configured to mate with the at least one partition, and wherein, when so mated, each of the plurality of wells and plurality of ceilings define a discrete substantially sealed internal volume.
3. The container of claim 1 , wherein the perimeter rim of the molded fiber tray is disposed substantially orthogonal to the outer surface and the inner surface.
4. The container of claim 3 , wherein the perimeter rim of the molded fiber tray comprises an outer rim disposed adjacent the outer wall and an inner rim disposed adjacent the inner wall, and wherein the inner rim is adjacent the at least one well.
5. The container of claim 1 , wherein the perimeter rim of the molded fiber lid is disposed substantially orthogonal to the outer wall and the inner wall.
6. The container of claim 5 , wherein the perimeter rim of the molded fiber lid comprises an outer rim disposed adjacent the outer surface and an inner rim disposed adjacent the inner surface, and wherein the molded fiber lid further comprises at least one soffit disposed between the inner rim and the at least one ceiling.
7. The container of claim 1 , wherein the molded fiber lid further comprises at least one tab extending from the perimeter rim.
8. The container of claim 2 , wherein the at least one partition comprises a major partition extending from a first side of the molded fiber tray to a second side of the molded fiber tray.
9. The container of claim 8 , wherein the at least one partition further comprises a minor partition extending from a third side of the molded fiber tray to the major partition.
10. The container of claim 2 , wherein the at least one partition at least partially defines a groove.
11. A container comprising:
a molded fiber tray comprising:
a unitary fiber body defining at least two internal wells, separated by a partition comprising a first well surface, a second well surface, and a partition uppermost surface spanning the first well surface and the second well surface, wherein the molded fiber body comprises a perimeter engaging wall extending upward from a perimeter rim of the molded fiber tray and at least partially surrounding both of the two internal wells, the perimeter engaging wall comprising an inner surface, an outer surface, and an uppermost surface spanning the inner surface and the outer surface, wherein the perimeter engaging wall uppermost surface at least partially defines a groove therein, and wherein the perimeter engaging wall uppermost surface is disposed at an elevation different than an elevation of the partition uppermost surface; and
a molded fiber lid comprising:
a unitary fiber body comprising at least one ceiling, a soffit extending from the at least one ceiling and defining an internal recess, a perimeter engaging receiver extending upward from a perimeter rim of the molded fiber lid, the perimeter engaging receiver at least partially defined by an inner wall, an outer wall, and an uppermost wall spanning the inner wall and the outer wall, wherein the partition is configured to be removably received in the internal recess, wherein, when so received, the soffit contacts at least one of the first well wall and the second well wall,
wherein the perimeter engaging wall is configured to be removably received in the perimeter engaging receiver,
wherein, when so received, the inner surface contacts the inner wall, the outer surface contacts the outer wall, and the uppermost surface contacts the uppermost wall,
wherein the groove and the uppermost wall define a small volume into which liquid that penetrates past sealing surfaces is contained to limit leakage and act as a pressure relief, and
wherein, when so received, the at least one internal well and the at least one ceiling define a substantially sealed internal volume.
12. The container of claim 11 , wherein the groove is continuous and extends along the uppermost surface.
