DEFINITION

Classification: 141/115

(under the class definition) Apparatus having means (1) to obviate spillage or escape of material from the system after the separation or disconnection of the receiver from the filling means or (2) for the removal of contents material from the receiver. The means to obviate spillage or escape of material from the system may act either through the filling head means, i.e., by reversal of operation, or by pouring off or extracting contents material already in the receiver, the means acting in either event beyond the last point of stoppage of flow by the filling head means.

(1) Note. This subclass does not include apparatus for simultaneously filling and overflowing the receiver unless a flow line is provided, (i.e., spilling out) nor for overflowing and collecting spilled contents material.
