Abstract: A container for use with a vacuum truck includes a container body. The container body defines a door opening and a container closure including a door panel sized to fit the door opening. The door panel is hingedly attached relative to rear frame elements at the hinge side and is movable to occupy the door opening. The door panel defines a drain port under a horizontal beam. The drain port includes a stopcock having an open and a closed state. The stopcock is selectably movable from the open to the closed state or from the closed to the open state. The container body defines at least two additional ports situated above the midpoints of the frames and includes fittings to engage vacuum hoses such that any volume the vacuum truck draws through one of the hoses, the container body draws a corresponding volume through the other of the two ports.

A bottom end of the lid is provided with a hollow inner cavity, and an inner side wall of the hollow inner cavity is provided with a thread. An upper end of the lid is provided with at least two sliding grooves. The present invention can be used for sealing container filling tubes. Moreover, the lids of the present invention can be assembled to form any combined shapes, thereby reducing garbage pollution and promoting environmental protection.
