Abstract

Disclosed is a sealer built into the body of a container that makes sealing toner containers possible without the use of complicated and expensive machinery. A conveyor system currently carries plugs to filled contains where they are inserted. Precise positioning of the plug to the container and a substantial insertion force makes the plugging machinery the most costly equipment on a packaging line. Poor container and plug quality cause down time and machine maintenance. As shown in the Figure 1, a flexible plastic diaphragm 10 having at least two perpendicular slits 16 and 18 is added to an opening structure 12 of a container (not shown). In Figure 2, a toner filling nozzle 14 passes through diaphragm 10. After filling, nozzle 14 withdraws and the elastic forces of the deflected diaphragm 10 returns it to its closed position. A quick hardening glue applied from an overhead dispenser to slits 16 and 18 provides a sealed container free from accidental openings.
