Container includes a base and a lid. The base has a base rim forming a base channel including a bottom wall, an inner sidewall, and an outer sidewall to define a channel space, a lock projection extending into the channel space from a first portion of the base rim, and a lever projection extending substantially outwardly from a second portion of the base rim. The lid has a lid rim forming a lid channel including a bottom wall, an inner sidewall, and an outer sidewall. The lid has a closed position in which the lid channel is aligned with and disposed at least partially within the channel space. The lever projection is configured to pivot upon application of an external force to cause the lock projection to move out from the channel space and to urge at least a portion of the lid rim out of the base channel.

1. A container comprising: a base having a base rim forming a base channel including a bottom wall, an inner sidewall, and an outer sidewall to define a channel space, a lock projection extending into the channel space from a first portion of the base rim, and a lever projection extending substantially outwardly from a second portion of the base rim and configured to pivot about a hinge formed in the base channel, the hinge comprising a pair of pleats formed in the base channel, the pair of pleats each being formed on an opposite side of the lever projection and proximate the lever projection; anda lid having a lid rim forming a lid channel including a bottom wall, an inner sidewall, and an outer sidewall,the lid having a closed position in which the lid channel is aligned with and disposed at least partially within the channel space of the base channel and the lock projection disposed to resist lifting of the lid channel out of the base channel, andthe lever projection configured to pivot upon application of an external force to cause the lock projection to move out from the channel space and to urge at least a portion of the lid rim out of the base channel. 2. The container of claim 1, wherein the lock projection is disposed above the lid channel outer sidewall in the closed position. 3. The container of claim 1, wherein the lock projection is disposed on the base channel outer sidewall, the base channel inner sidewall having an inner lock projection disposed opposite the lock projection and extending into the channel space to further resist lifting of the lid channel out of the base channel in the closed position. 4. The container of claim 3, wherein the lid channel inner sidewall defines a notch to receive the inner lock projection in the closed position. 5. The container of claim 3, wherein the inner lock projection is configured to move out from the channel space when the lever projection is pivoted. 6. The container of claim 1, wherein the lock projection is formed by an undercut in the base rim. 7. The container of claim 1, wherein the lock projection is disposed beneath the at least a portion of the lid rim when in an open position to support the at least a portion of the lid rim. 8. The container of claim 1, wherein the lock projection is disposed proximate the lever projection. 9. The container of claim 1, wherein the lock projection comprises a pair of lock projection parts, each of the pair of lock projection parts being formed on an opposite side of the lever projection and proximate the lever projection. 10. The container of claim 1, wherein the lever projection is disposed at a corner of the base rim. 11. The container of claim 1, wherein the lever projection has a bottom surface to define a fulcrum about which the lever projection pivots. 12. The container of claim 11, wherein the bottom surface is arcuate. 13. The container of claim 1, wherein a top surface of the lever projection defines a recess proximate the base channel. 14. The container of claim 1, wherein a plurality of ribs are disposed on a bottom surface of the base channel bottom wall. 15. The container of claim 14, wherein the plurality of ribs extend along the inner sidewall and the outer sidewall of the base channel. 16. The container of claim 1, wherein the base has a base bottom surface defining a base stacking feature, the base stacking feature being shaped to align with a lid stacking feature of a similarly shaped container. 17. The container of claim 1, wherein the lid and the base are formed of sheet plastic.
