US Patent 11767166 Roll out cart collar

A container assembly includes a container body having a side wall extending upward from a base to define a mouth. A lid is pivotably secured to the container body and is pivotable between an open position and a closed position over the mouth of the container body. A collar is secured to an upper edge of the side wall of the container body. The collar reinforces the mouth of the container to prevent deformation thereof, such as by bears, and access between the lid and mouth of the container.
