Abstract

Claims7
A disposable bailer comprising:
- an one piece elongated tube constructed of a resilient polymeric material with lower fluid inlet and upper fluid outlet ends of the tube, both ends being integral with the tube and tapered;
- an inlet valve comprising an upwardly facing conical valve seat formed in the tapered lower fluid inlet end of said tube and a valve member for engaging said valve seat from above, the tapered lower fluid inlet end of said tube being constricted to a dimension sufficiently narrow to constrain longitudinal motion of the valve member upwardly out of the tapered lower fluid inlet end of said tube;
- the inlet end of the tube being continuously molded with the tube to form an internal cavity in the tapered portion of the inlet end for containing said valve member.
