ABSTRACT:
Trigger actuated pump sprayers for application of a great variety of household and industrial liquids are improved for dual service use by inclusion of a spout, which can be operated in a closed mode or an opened mode, mounted to the pump housing and a tubular conduit extending internally of the housing and the cap from the spout to at least the cap for flow of liquid directly from the container on which the sprayer is mounted to the spout whereby liquid may be dispensed from the container through the spout when the user of the sprayer needs larger quantities of the liquid than can conveniently be obtained via the spray pump.
