Abstract:
1. A tote bin liner having a liner wall to form a container, said liner wall including a transfer spigot which provides a passage from inside said liner to a tote bin outlet, said transfer spigot being adapted to have a valve mounted thereto to provide a controlled outlet from the tote bin outlet, the transfer spigot comprising: a tubular body which defines said passage, the tubular body having a first opening on a distal end thereof; an annular surface located around the opening; a rupturable membrane sealed to said annular surface by a continuous seal around said first opening, said continuous seal being located on said annular surface; the tubular body being shaped and configured such that when in use and said valve is mounted to the body, a seal on the valve will clamp the membrane against the annular surface, wherein the annular surface has a radially inner portion and a radially outer portion, and said continuous seal is operatively located on said radially outer portion, while the radially inner portion is adapted to allow the seal of the valve which is brought into engagement with the tubular body to form a seal therewith, with the seal of the valve being arranged to isolate the continuous seal from elevated temperature and pressure arising from sterilizing fluid passing through the passage to sterilize the membrane.
