Child-resistant cover for containers

Abstract

A container cover is provided which prevents young children from gaining access to the container's contents. The container has an opening at one end and a latch lip adjacent to the opening. The cover comprises a plate having at least one opening and a handle secured to the plate and having at least two grips, a releasing grip and a non-releasing grip. Two latching means secure the plate to the latch lip, one of the latching means is attached to the releasing grip and passes through the plate opening. The releasing grip has means for releasing the latching means such as lifting, sliding or rotating. The container may be used for containers for materials which may be harmful if handled or ingested. A particular application of the cover is on a magazine for soluble solids to be dissolved by a liquid, for example, in treating swimming pool water. The magazine is a component of an apparatus for dissolving and dispensing soluble material including a container having an upper and a lower chamber. The upper chamber is separated into a first and a second compartment. A rotary receptacle in the first compartment receives liquid through an inlet in the first compartment and is periodically emptied, releasing precisely the same amount of liquid each cycle. The second compartment contains a magazine which holds soluble solids to be dissolved by the liquid. A control valve regulates the amount of liquid contact with the solid. The lower chamber receives the solution from the second compartment and through valve means releases the solution into the liquid system to be treated.
