Ah, I didn't realise it screwed together, that blows my theory out of the water!

(Unless that's just a feature for when not in use? But doubtful. I imagined the red fabric an area for "packing" to form a moving seal between inner & outer, but yes a long shot....).

Good luck in finding out how it was used & please let us know.
