A lubrication system consisting of a metering valve for providing a measured quantity of lubricant to parts to be lubricated, a pump for moving lubricant to the metering valve through distribution lines, and a reservoir dispenser of novel design from which the pump draws lubricant. The reservoir dispenser is formed of (1) a bag of flexible impermeable plastic, and (2) a rigid flat bottom plate to which the open end of the bag is fastened and sealed. The top of the bag is opposite to the open end, is relatively rigid, and is provided with a check valve which allows egress of fluid from the bag but not ingress. A pair of crossed ribs are formed on the underside of the top to prevent undesired sealing of openings in the flat bottom plate. The side walls of the bag are relatively thick for the lower approximately one half portion and are relatively rigid throughout such portion. The upper slightly more than one half portion of the side walls is thinner, relatively flexible, and tapers to the portion adjacent the top. The portion adjacent the top is thinnest so that under atmospheric or higher pressure the upper portion of the side walls folds down into the interior of the bag as the top descends into the bag. The flat bottom plate is provided with two automatic valves, one being an outlet check valve allowing egress from the bag but not ingress. This outlet valve is connected to the pump for supplying lubricant to the meter valves. Lubricant is supplied to the reservoir as needed through an inlet valve in the bottom plate, but except when lubricant is being supplied to the reservoir, the inlet valve is sealed. A quick-connect lubricant fitting is secured to the inlet valve.
