Abstract
A multi-compartment container includes a partition member located in the container a pair of lids pivotally attached to the partition member. Each lid includes a pair of integrally molded hinge arms and one or more integrally molded cantilevered hinge pins extends laterally from each of the hinge arms of each lid along a common pivot axis. Spaced sockets are formed in the partition member for pivotally receiving the cantilevered hinge pins of each lid. Some of the hinge pins of each lid have a beveled end surface, and the partition member has a beveled surface adjacent some of the sockets complementary to the hinge pin beveled end surfaces. With this arrangement, each of the lids can be installed on the container by aligning the beveled surfaces of the pins and partition wall, and forcing the hinge pins in a camming action along the beveled surfaces until the hinge pins snap into their respective sockets. Each lid has at least one rib integrally formed with a lower surface thereof and a channel integrally formed with the upper surface thereof. The channel is sized to receive a rib of an adjacent lid when a plurality of lids are stacked together.
