Abstract

An all plastic one piece blow molded pressure vessel and sprayer combination shows a bottom closure with upwardly inclined feet. Internal pressure causes the upward and inward portion of the feet to descend such that the feet remain in good contact with a planar surface on which the vessel is resting, such that the bottom does not become bulged outwardly and rock.
