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.

Abstract
A device is disclosed which provides direct and effective incorporation of material (such as medicine) from a separate container into the contents of a liquid dispensing device. The device has a hollow sleeve extending outwardly, an openable closure, a securing member which engages a mating member on the container, and a conduit (such as a needle) to provide fluid communication between the device and the container, with the fluid communication occurring upon attachment of the container to the device. The device can also provide for attaching the separate container to the dispensing device but without initially establishing liquid communication between the two.

9. A system for connecting a diluent source within a first container to a vial containing a medication, comprising:
-
a vial adaptor having an open proximal end, a distal end, and a wall section between said proximal end and said distal end, wherein the wall section comprises a flange adapted to releasably engage a corresponding groove on the vial, said vial adaptor further comprising a conduit attached at said distal end of said vial adaptor, said conduit having a distal end and a sharp proximal end adapted to pierce a seal on said vial, said conduit further defining a first lumen that extends from the proximal end of the conduit through the distal end of the vial adaptor;
said vial adaptor further comprising a second wall section forming a channel that extends distally past the distal end of said conduit; anda connector having a proximal end, a distal end and a third wall section disposed between said proximal and said distal ends, wherein the proximal end comprises a recessed wall section sized to fit within the channel formed by said second wall section of said adaptor, said connector having a second lumen extending therethrough and wherein said distal end of said connector is adapted to attach to said container;
said connector further comprising a reclosable valve that is ordinarily closed to prevent fluid communication through said second lumen;said vial adaptor and said connector being adapted to releasably and sealingly connect at the distal end of said adaptor and the proximal end of said connector, such that said recessed wall section slides within the channel formed by said wall section upon sliding movement of the distal end of the adaptor and the proximal end of the connector towards each other such that said conduit contacts said valve causing it to open to allow fluid communication through said valve and said first and second lumen. - View Dependent Claims (10, 11, 12, 13)

14. A liquid dispensing device comprising:
-
a hollow casing having inner and outer sides, said inner side defining an interior which can contain a fluid; an opening in said casing providing fluid communication between said interior and the exterior of said casing; a hollow sleeve surrounding said opening and extending outwardly from said outer side, said sleeve having an interior; an reclosable valve on the interior of said sleeve, said valve being normally closed and being openable only from outside said casing; a flange on the interior of said sleeve for releasably engaging a groove on a neck of a vial, said vial having an interior which can contain a medicament and a piercable seal which provides fluid communication between the interior and exterior of said vial; a conduit having a sharp distal end at least partially within said sleeve which pierces said seal and a proximal end in fluid communication with the interior of said hollow casing, such that when said distal end pierces said seal, fluid communication is established between said interiors of said hollow casing and said vial; and a second flange within said sleeve and spaced apart from said first flange, said second flange also engagable with said groove on said vial, and spaced apart from said seal a sufficient distance such that when said vial is inserted into said sleeve, said second flange engages the groove on the vial such that the vial and said sleeve are secured together but said conduit does not contact said seal and no fluid communication exists between said interiors of said vial and said hollow casing. - View Dependent Claims (15, 16)

17. An adaptor for releasably joining a vial with a liquid delivery device, comprising:
-
a vial adaptor comprising a front open end sized to receive a neck of said vial, a flange for engaging a corresponding groove on said vial, a back closed end, a wall having an inner and outer surface extending distally from said closed end to form a channel, a hollow needle extending through said back end and into said channel; and a connector comprising an outer wall having a proximal end and a distal end and a recessed wall sized to fit within the channel formed by the wall of said vial adaptor and having an inner and outer surface, said recessed wall extending proximately from said outer wall and forming a lumen to receive the needle such that fluid communication is achieved between the needle and said lumen, and wherein a reclosable valve is located within said lumen, and wherein said outer wall is adapted to be releasably connected to an opening in said liquid delivery device. - View Dependent Claims (18, 19, 20)
