Packaging Container for Powder Material

The package comprises an outside container 10 with a suitable cover 11, which is fixed to container 10 by a tear strip 12.

The powder material is contained in a flexible bag 14 the open end of which is attached to a snap ring 15. Flexible bag 14 is closed below snap ring 15 by a suitable tie member 16. To load the powder material, such as electroscopic toner for example, into a using system the first step is to remove tear strip 12 and lift flexible bag 14 out of the container. Snap ring 15 is designed to lock into a holder ring 17 which is attached to the using system. Snap ring 15 has a plurality of locking members 18 and holder ring 17 has cooperating inwardly tapered segments 19 so that the snap ring can be locked into holder ring 17, by pushing the snap ring locking members past the end of the taper of segments 19. In this manner a compressible gasket between snap ring 15 and holder ring 17 provides an air-tight seal. Once the snap ring is secured into the holder ring, the tie member 16 is removed and the powder material is loaded into the hopper. The bag can be folded to the side and act as a cover, or the bag can be removed and replaced by a cover that has the same locking configuration. To remove the bag, the snap ring 15 is twisted approximately 30 degrees so that the locking members 18 then match segments 20 of holder ring 17, which are tapered in the opposite direction.
