An end wall (23) of the cap (17) has a smooth inner surface (26) confronting the end wall (25) of the plug.. The plug (16) and sleeve (21) have two discrete passageways (27 and 32) formed between the discharge conduit (15) and the discharge orifice (24) located in the cap end wall (23). The passageways (27 and 32) are capable of being aligned so as to be open or mis-aligned so as to be closed in selected rotative positions of the cap in alternating off, stream and spray positions.</p> |
