Small 0.6-1 liter bottle rated to 100psi (6.9bar) 1

[ESTinker]

Anyone know of a company that makes a bottle either aluminum or stainless 0.6-1 liter that is rated up 100psi(6.9bar) of compressed air?

Everything out there is either rated with no pressure (standard cheap water bottles) or overkill at 1000+psi(69bar) (expensive scuba tanks or paintball cylinders), something in between the cheap water bottle and scuba tank would be nice.

You can buy bike pumps with a storage cylinder attached.
