Abstract: Hinge and latching mechanism for containers having a cover and a base includes a latch which, at its upper portion, is shaped to hook over a strike integrally disposed on the cover. The lower portion of the latch rotates about a pin located between a pair of feet which are provided with hooks to engage a flange extending from a lip on the base. The hinge includes a body and two legs and the former is also shaped to securely engage a second strike also located on the cover. Each leg has a foot which is also hooked to engage the flange of the base. To further secure the hinge and latch, each hook is fastened together and to the container. This structure ensures that hinge and latching mechanism are especially adapted for heavy duty applications while still being light in weight and small in size.
