Does anyone know of a cup same as tommee tippee first cup but with a valve?

[Dragonhart]

Looking for a cup with

1. A valve.
2. As few parts as possible.
3. No plastic lid to cover the spout (but something I can throw in the bag so it has to be covered in some way like the fold down type)
4. About the same size as the tommee tippee first cup (which I love but when we go out dd shakes all over herself in fits of giggles).

Does such a thing exsist?

a small avent magic cup? It has a valve and small spout but has a seperate lid.

Thanks seona. Thats what I used when ds1 was using them but I always lost the valves! They are very good though.
