摘要

Provided are coating liquid reservoirs for use with a fluid inlet of a spray gun, the coating liquid reservoir comprising: a flexible outer pouch and a flexible inner pouch nested within the outer pouch, the inner pouch defining a coating liquid chamber, wherein upon supply of an external pressure source into a pressure zone between the inner and outer pouches, pressure is applied to the coating liquid chamber thereby expelling a liquid from the coating liquid chamber. The outer pouch inflates upon application of pressure in the pressure zone. Methods of making and using the same are also provided.
