9. A liquid collection device, comprising:
-
an elongated liquid collection tube defining a chamber for collecting a liquid, having an inlet which receives the liquid to be collected and an outlet through which a gas in said chamber may be exhausted, and including a tubular member projecting into said chamber which is in communication with said inlet; an annular reservoir defined by said tubular member and said collection tube, and an additive being contained within said annular reservoir; a rotatable valve cap including a first body and a second body, said first body being removably mounted to said collection tube and said second body being rotatably mounted to said first body, each of said first body and said second body including at least one vent which are alignable by rotation of said second body; and a hydrophobic filter supported by said cap between said outlet and said at least one vents.
