Abstract
An all-plastic, continuous trigger sprayer is contemplated that avoids the use of metal parts, elastomers, or other disparate and non-recyclable materials. A reservoir diaphragm is provided within the sprayer head, interposed between the actuation mechanism and the outlet, so as to ensure a steady flow of dispensed fluid is delivered even after actuation has ceased.
