A tote bin liner has a transfer spigot ( 2 ) through which product may be introduced into or emptied from the liner. The transfer spigot has a membrane ( 6 ) which seals the interior of the liner. The membrane is sealed to the spigot on an outer face ( 11 ) of the spigot which is configured so that the membrane will be clamped in position during piercing of the membrane by a cutter. The invention extends to a cutter assembly for use with a tote bin liner. The cutter assembly ( 40 ) may be adapted to be moved past a valve closure member ( 22 ) for the valve ( 20 ), the assembly furthermore including an arrangement ( 78 ) for sterilising the interior of the valve and the outer face of the membrane, and an actuator ( 43 ) for moving the cutter in order to pierce the membrane.
