Hopper for containing drywall joint compound

Image Number 2 for United States Patent #4440410.

A hopper or container for containing drywall joint compound or "mud" used in the "taping and floating" of seams between drywall panels, which hopper includes a shaped metal tank which tapers to define a closed funnel at the bottom, and a pump support projecting from the tank near the bottom, with a pump access opening in the pump support to receive a filler pump for pumping the joint compound from the tank on demand. The hopper can be fitted with wheels to better facilitate mobility, and is provided with a hinged lid fitted with a gasket, for loading the joint compound into the tank and maintaining a tight seal between the closed lid and the top of the hopper.
