Abstract
A receptacle in which a collapsible fluid-holding container is disposed within an outer container of substantially fixed shape. The mouths of the containers are connected and formed internally to admit air between the containers via apertures through the side of the outer container mouth, whereby the inner container collapses as fluid is dispensed, thereby minimizing the intrusion of air into contact with the fluid. A cap closes the mouths and side apertures to seal the contents of the receptacle.
