A devices designed to pour coffee beans into vials with ease.  No jamming as the beans are constrained into an ever tighter channel.  This design allows the beans to move freely into the vial.  It can work as a scoop or it can be scooped our poured into.

This model is for vials with a 22mm ID opening and 27mm id at the threads.  I wrote a program (in go) to generate this model so making new versions to vit other vial sizes is trivial.
