ABSTRACT:
The device shown herein is made of essentially two parts one of which parts is essentially a hollow tube closed for a substantial distance at one end having a hollow cap with only a side opening therein. The second part is a rod with an end portion adapted to snugly fit into the interior of the cap of the first part. This second part is rotatable on its linear axis and when held in a particular axial position, the second part end portion is adapted to block the side opening so as to cut off communication between the interior and the exterior of this cap. This second part end portion has a cut-away section so that when this second part is rotated axially, preferably in the neighborhood of 180.degree. , this cut-away section is positioned adjacent to the side opening of the cap of the first part thereby allowing communication of fluid through the opening in said cap.
