1. A liquid dispensing device comprising:

  • a container for fluid having an interior, an exterior, and an opening which provides fluid communication between the interior and the exterior;

    a vial having an interior, a neck, a groove in the neck, and a piercable seal;

    a connector attached to the container surrounding the opening, the connector having a hollow channel disposed therein and in fluid communication with the opening in the container, the channel having a reclosable valve disposed therein, the valve being normally closed; and

    a vial adaptor having an open proximal end, a closed distal end, a wall disposed between the distal and proximal ends, the wall comprising a flange which releasably engages the groove on the neck of the vial, and a hollow conduit passing through the closed end and having a distal end extending beyond the closed end and sized to fit within the hollow channel of said connector, and a sharp proximal end adapted to pierce the seal on the vial;

    wherein the vial fits within the open proximal end of the vial adaptor and the flange engages the groove to hold the vial in the adaptor, and the connector and adaptor slidably attach such that the distal end of the hollow conduit in the vial adaptor slides within the hollow channel in the connector and contacts the valve causing it to open, and the proximal end of the conduit pierces the seal on the vial, thereby establishing fluid communication between the interior of the container and the interior of the vial.
