Abstract
This invention relates to the packaging and subsequent removal of particulate matter that tends to stick in its storage container. Particular application of the present invention is to cartridges for storing marking materials such as electrophotographic toners and solid ink jet inks. A mechanism and process for increasing visibility into a container holding particulate matter is disclosed. The cleaning mechanism includes a drive mechanism capable of moving a cleaning member proximate to the inside surface of the container.
Claims25
A mechanism for increasing visibility through a portion of the inside surface of a container that holds particulate matter, comprising:
- a. a drive mechanism having a movable member positioned to be moved by the drive mechanism along the inside surface of the container;
- b. a cleaning member, connected to the movable member and positioned to travel proximately to the inside surface of the container when the movable member is moved;
- and
- c. a switching mechanism, cooperating with the drive mechanism, for activating movement of the movable member by the drive mechanism.
A process for increasing visibility through a portion of the inside surface of a container that holds particulate matter, comprising:
- a. connecting a cleaning member with a movable member of a drive mechanism;
- b. positioning the movable member such that the connected cleaning member moves proximately to the inside surface of the container when the movable member moves;
- and
- c. activating the drive mechanism to move the movable member.
A cartridge for storing marking materials, said cartridge having an inside surface, comprising:
- a. a drive mechanism having a movable member positioned to be moved by the drive mechanism along the inside surface of the cartridge;
- b. a cleaning member, connected to the movable member and positioned to travel proximately to the inside surface of the cartridge when the movable member is moved;
- and
- c. a switching mechanism, cooperating with the drive mechanism, for activating movement of the movable member by the drive mechanism.
