[ISP] Container - well, I suppose it could be used as one but that is not its purpose, so no. [Raak] Rubber - yes.

Lib started it...

[Lib] Recreational - only in the loosest sense in that you would indeed use it to bring you some form of pleasure and I can't see a business usage, but I think I would have to say no overall. [ISP] Batteries - no - and completely no to where you seem to be headed :)

[Raak] Protective covering - no [ISP] sporty/gamey - no [Inkspot] Kitchen based - no (although in fairness, you could use or store it there if you wanted - but it would be most unusual) [Raak] Mackintosh - no [Projoy] Wellingtons - no [ISP] Eraser - no.

Just to elaborate a bit on the response as to whether it was a recreational activity, I might have unwittingly misled you with my reply. The object is used as a recreational activity, in that you would utilise it in your spare time and for fun, but it would be unlikely to have a a long term usage, like a hobby, or a passtime, hence my answering with a no. Hope this helps...

[Raak] Round - yes, it is!

[Inkspot] Hollow - hmm, sometimes yes, sometimes no. I think, however, that in the traditional understanding of hollow, you would not say that it was, so once again I'd plump for overall no.
