Abstract
A device is provided for storing a supply of particles for use in a developer unit of an electrophotographic printing machine. The device comprises an open ended container defining a chamber in communication with the open end thereof. The particles are stored in the chamber of the container. The device further comprises a puncturable seal attached to the open end of the container for sealing the chamber. The container is installable into the developer unit without removal of the seal.
