Abstract
A compression sprayer is provided with a bag in the tank for holding the product to be sprayed. The bag may be initially provided in folded, collapsed, sealed condition containing the product in concentrated form. The folded bag is then mounted interiorially of the tank and filled with liquid to provide the solution to be sprayed. The bag unfolds as it is filled and thereafter is coupled with the tank outlet. An internally mounted pump assembly pressurizes the interior of the tank to compress the bag which collapses as the contained liquid is sprayed.
