ABSTRACT:
Embodiments of the present invention are directed to a pierce fitting or member for penetrating a container to access the interior of the container. The pierce fitting is configured to cut a flap through the surface of the container. In one embodiment, a device for penetrating a container to access an interior of the container comprises a pierce member including an external surface and an internal surface forming a hollow interior extending between a proximal end and a distal end. The distal end has a slanted surface with a pierce leading edge on a first side between the external surface and the internal surface. The external surface expands outwardly in a region proximal of the distal end in a direction toward the proximal end except on a second side opposite from the first side.
