Chemical storage container with locking hinge
First Claim
1. A container comprising a receptacle and a lid rotatably connected to the receptacle via a hinge, wherein the hinge comprises a mating pin and knuckle, wherein the pin is configured for one-way insertion into the knuckle such that the pin is locked in an axially fixed position relative to the knuckle when mated with the knuckle, and wherein the pin and knuckle freely rotate back and forth relative to each other within a defined angle of rotation between an open lid position and a closed lid position when the pin is mated with the knuckle, wherein the lid has a latch configured to seal the receptacle closed when in the closed lid position, and wherein the container further comprises a handle having two ends each rotatably secured to an opposing side of the receptacle, wherein the lid has handle guides attached to opposing sides of the lid and extending outwardly from the lid, wherein the handle guides are positioned to move the lid from the closed lid position to the open lid position when rotating the handle from one side of the receptacle to an opposite side of the receptacle.
