A disposal container having a container body, a seal section disposed on top of the container body and having an opening with a seal band around the opening, a transfer barrel pivotally mounted on the seal section, the transfer barrel having a substantially spherical outer surface with an opening on the outer surface, and a handle pivotally mounted on the seal section. The handle and the transfer barrel are mounted to rotate coaxially in synchronization. When the handle and the transfer barrel are rotated to an open position, the opening of the transfer barrel is above the seal band; when they are rotated to a closed position, the opening of the transfer barrel is below the seal band. In another embodiment, a lid rather than a handle is provided and coupled to the transfer barrel to rotate it. Springs are provided to urge the lid toward an open position.
