ABSTRACT:
A double-walled spraying device having an air space in an outer container formed between resilient side walls, the inner side wall forming an inner container holding a fluid to be sprayed, and an outer container holding air. The top of the device is also double-walled, the inner top wall being substantially rigid and the outer top wall including an annular diaphragm which is conically convex in the normally closed position of the diaphragm. The space between the two top walls comprises a mixing chamber accessible to the fluid in the inner container and to air under manual pressure from the outer container to form a spray through a perforated dome.
