Replaceable reservoir

US-8540172-B2

Abstract

A sachet ( 1 ) having walls of flexible material is disclosed. The walls are joined so as to form an impermeable seal, thereby defining a cavity within the sachet ( 1 ). A conduit ( 2 ) passing through the seal and having inner and outer ends is disposed with the inner end within the cavity and the outer end outside the sachet ( 1 ) such that the cavity is in fluid communication, via the conduit, with the outside of the sachet. The cavity contains a volume of liquid ( 8 ) in use, and the conduit ( 2 ) is adapted to prevent the liquid ( 8 ) flowing from the cavity without the application of an additional stimulus, irrespective of the orientation of the sachet ( 1 ).
