Mask Shipping and Handling Container

This container minimizes damage when moving masks from station to station during processing and when shipping masks after processing.

The stackable container consists of a clear acetate butyrate top and bottom sections 1 and 5 which are held together by snap closures (not shown). Up to four masks 3 can be held in position, interleaved with thick, rigid, clear PVC separator trays 4. Figs. 1-3 shown only one mask 3 and one separator tray 4. The stack of masks 3 and trays 4 are held securely both horizontally and vertically by a polypropylene spider 2 that acts as a spring which is compressed when the cover is snapped into place. The peripheral ribs of the spider 2 exert pressure around the inactive (unprocessed) outer edge of the mask, and thus prevents the mask from moving in either direction. This pressure can be conveyed thru a top tray 4, when provided, between the spider 2 and mask 3.

The container can transport different numbers of masks by varying the thickness of the separator tray 4. For example, a single mask 3 would be accompanied by a thick tray or trays 4, while a plurality of masks would be interleaved with correspondingly thinner trays. Accordingly, a handling, storage and shipping system is provided which can accommodate processed metal masks varying in thickness and number without modifying the container.
