Abstract

An apparatus and process for storing beads in a liquid medium and for draining and dispensing said beads essentially in the absence of said liquid medium is described. In one embodiment, the apparatus is designed so that the liquid medium in which the beads are stored can be captured in a separate compartment from the bead-containing compartment and the beads can be delivered without the liquid medium when the apparatus in inverted. This apparatus is designed so that the liquid medium will join with the beads for storage in the bead-containing compartment when the apparatus is upright. In another embodiment, the apparatus includes a bottle with a removable, threaded inner container which is used to drain the liquid medium from the beads prior to attachment to a separate bead dispenser.
