    摘要: The invention is a trigger sprayer comprising a tubular nozzle bushing and a nozzle cap rotatable on the bushing. The nozzle cap has an end wall with a first swirl chamber formed on the rear face thereof offset from the axis. Passages to a second chamber are diametrically opposite the first chamber. Both chambers have orifices directed out the front of the cap. The first orifices is surrounded by a foaming sleeve. The second orifice is positioned forward of the first orifice so that the spray cone emanating from the second orifice does not hit the foaming sleeve. The cap can be rotated to connect liquid from the delivery tube to the swirl chamber for one or the other orifices.
