ABSTRACT:
A device is provided for storing a supply of particles for use in a developer unit of an electrophotographic printing machine. The device includes an open ended container defining a chamber in communication with the open end of the container. The particles are stored in the chamber of the container. The device also includes 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. The device further includes an internal seal attached to the open end of the container. The internal seal is internal to the puncturable seal. The internal seal has a surface closely conforming to the open end of the container. The internal seal is removable from the open end of the container by displacement of the internal seal into the chamber of the container.
