  • Patent number: 5427308
    Abstract: Containers having a container carrying body (30) and a removable lid (29) portion, both formed of thin light weight sheet material, and including a combined latching (13) and handle (9) system carried by the container carrying body (30). The handles (9) and locking tabs (13) are integrally attached to the carrying body (30). The lid (29) includes an opening through which the handle (9) can pass, and slots which can be engaged by the locking tabs (13) to secure the lid (29) to the container body (30). The tabs (13) are placed into locking position when the handles (9) are lifted into the carrying position through the lid (29). The handles (9), locking tabs (13), and container body (30) may be stamped from a single piece of thin light weight sheet material, thereby simplifying its construction and adding to the economy of the container. In one modification, the configuration of the carrying handles (9) allows a slotted liner ( 27) to be slipped over the handles (9), before the lid (29) is attached.
