Summary: | A vacuum operated fluid collection container incorporates a float valve for automatically disconnecting the container from an active vacuum source when a predetermined filled condition occurs. The valve is hingedly mounted adjacent an outlet port to which the vacuum source is attached and adapted to depend below the outlet port during normal operation and to float upward for obstructing the outlet port to terminate filling operation when the container is filled. The valve mechanism may be of thermoplastic material in a single, unitary piece. In such form it is particularly effective and inexpensive to manufacture and, accordingly, it is suitable for use with disposable vacuum filled liquid containers. |
