A tube (102) attachable at one end (104) to a container (12) of fluid (60) is provided at the other end (106) with an end cap (120) in which is formed a fluid discharge opening (154). The end cap (120) includes a first portion (146) inserted into the tube (102), while a second portion (148) remains exterior thereto. The inner surface (162) of the tube (102) together with a fluid recess (170) formed in the outer surface (151) of the first portion (146) of the end cap (120) defines a fluid discharge passageway communicating with discharge opening (154). A slide valve (108) on the exterior of the tube (102) is biased into a closed position, precluding fluid transfer. An air vent recess (155) in the outer surface (151) of the first portion (146) of the end cap (120) terminates at both ends in capillary section (157, 160) of relatively reduced cross-sectional area. |
