A device for effecting transfer of material from a container by piercing the container. The device includes a fitment member that includes a portion having a bore and a base end capable of being attached to a container; a spout member that has a piercing end; and a portion of tube having an outer surface capable of mating in axial relationship with the portion of bore of the fitment member so as to form mating surfaces. The device preferably has a locking assembly that is adapted to lock the fitment and spout members together in a position whereby the piercing end is in piercing engagement with the container. The device also includes at least one sealing member that is arranged to seal the portion of tube and the portion of bore in a position between the locking assembly and the piercing end so as to leave the mating surfaces downstream including the locking assembly substantially cleansed of the flowable material.
