Self-closing drum lids with controlled closing rates

Abstract

Self-closing drum lids that automatically close at controlled rates are disclosed. When the lid is manually rotated to a fully open position, it automatically begins self closing with a transition from a relatively slow rate that allows a user to add material and/or remove material from the drum without having to hold the lid open by hand. After the slow-closing stage, the lid begins to close at a faster rate until the lid rotates to a fully closed position on the drum. The self-closing drum lids may be attached to a drum via a drum band, and may include a latching mechanism.
