Abstract: A replenishment receptacle for containing particulate material and replenishing the particulate material into a reservoir. The replenishment receptacle includes an enclosed container with an orifice for filing and removing particulate material and a closure with a slide cover for closing and sealing the container. Tab-like features on the closure, for locating it to the reservoir during transfer of the particulate material from the receptacle to the reservoir, are uniquely shaped and located for low cost manufacturing. The slide cover for closing and sealing the receptacle has a cellular urethane foam gasket bonded to the inner side and ramp-like features on the outer side to capture the slide cover, thus preventing it from being removed from the closure. In one embodiment the enclosed container and closure have features which engage and lock together the enclosed container and closure, thus preventing them from working loose and leaking during shipping and handling.
