Abstract:
A stackable dough storage containment system uses nesting stackable interlocking pan bodies having a locking system for connecting the bodies, such that a pan body in a stack can be locked to pan bodies stacked above and below it. The locking system includes locking members positioned on the outside of each pan body near its base, forming locking connections with locking interfaces located on the outside of each pan body near its top. In the preferred embodiments, the locking members are radial pins and the locking member interfaces are bayonet joints. This allows each pan body to be dropped into position in the open top of the pan body below and rotated slightly to form a secure connection. Vents in each pan body release gases generated during the rising process.
