A collection tank for use in a vacuum operated earth reduction system, the collection tank comprising a closed first end, an open second end defining a tank sealing flange and a body extending between the closed first end and the open second end. An internal chamber defined by the body, the closed first end and the open second end has a door coupled to the open second end and is configured to releasably seal the open second end. An automated door closer is coupled to a center of the door, wherein the automated door closer provides a closing force at the center of the door so that the closing force is equally distributed about a periphery of the door to seal the door against the tank sealing flange.

A material loading device includes a main body defining a receiving cavity and an opening. The receiving cavity receives materials. The main body defines a buckle groove at the opening. A buckle rod movably coupled to the main body at the opening buckles into the buckle groove. A foolproof mechanism is arranged on the main body. A thimble of the foolproof mechanism is slidably coupled to the main body. One end of the thimble is located in the buckle groove. When the buckle rod is buckled into the buckle groove, the buckle rod drives the thimble to slide relative to the main body. A display member of the foolproof mechanism is coupled to the thimble. The main body defines a plurality of recesses corresponding to the display member. The thimble drives the display member to slide relative to the recesses to switch the display member displayed through the recesses.

Aspects of the present invention are directed to a child-resistant container comprising a lid and a vial. The lid has a side wall, an inner surface and a lid cover. The lid cover includes a top, a bottom, and a front surface and at least two lid hooks protruding from the bottom surface. The vial contains an opening accessing a cavity and a rim extending around at least a portion of the opening, the rim having at least two moveable tabs partially affixed to the rim and movable about a pivot point. The movable tabs contain tab hooks above the pivot point for engaging with the lid hooks to secure the lid cover to the vial. The moveable tabs are displaceable outwardly away from the lid to disengage the tab hooks from the lid hooks by pressing inwardly on the moveable tabs below the pivot point.
