Abstract

A medicine bottle is formed with a neck that defines an opening and a closed bottom opposite the opening. A closure element is engaged with the neck to block the opening, and the closure element is formed with a fluid passageway. A fitting is positioned in the fluid passageway. The fitting is configured for receiving the hub of a needleless syringe, and a tube which has a proximal end is positioned in the bottle with the proximal end in fluid communication with the fitting. The tube also has a distal end disposed near the bottom of the bottle. Consequently, the syringe can be engaged with the fitting for drawing liquid from the bottle into the syringe without inverting the bottom of the bottle over the neck of the bottle, even when the bottle is nearly empty.

Claims

1. A liquid medicament dispensing apparatus, comprising:

a bottle formed with a neck defining an opening and a closed bottom opposite the opening, the bottle defining a chamber for holding liquid;

a needleless syringe formed with a hub and a barrel, the barrel being radially larger than the hub;

a resilient stopper positioned in the opening, the stopper defining a passageway;

a hollow fitting engaged with the stopper and defining a proximal end for receiving the hub, the fitting defining a continuous, unblocked fluid pathway both when the proximal end receives the hub and when the proximal end does not receive the hub; and

a tube in fluid communication with the fluid pathway of the fitting and distanced from the barrel of the syringe when the hub of the syringe is received in the fitting, the tube having a distal end disposed near the bottom of the bottle.

2. The apparatus of claim 1, wherein the hollow fitting is made of elastic material and defines a fluid pathway therethrough, the fluid pathway having a frusto-conical wall for guiding the hub of the syringe into close engagement with the fitting.

3. The apparatus of claim 2, wherein the neck of the bottle defines a proximal edge, and wherein the closure element includes a cap threadably engageable with the bottle and a stopper having a proximal surface, a distal surface, and a proximal flange, and the proximal flange of the stopper is positioned against the proximal edge of the bottle to establish a fluid seal therebetween when the cap is engaged with the bottle.

4. The apparatus of claim 3, wherein the passageway of the stopper defines a wall, and the passageway includes a distal segment for closely receiving the fitting therein and a proximal segment, and the wall of the proximal segment is radially distanced from the fitting to permit the fitting to expand when the hub of the syringe is engaged therewith.

5. The apparatus of claim 4, wherein the stopper is formed with a vent passage extending between the proximal and distal surfaces of the stopper.

6. The apparatus of claim 5, further comprising a cap engageable with the bottle when the stopper is positioned in the neck of the bottle.

7. A device for interconnecting a medicament bottle having liquid medicament therein, wherein the bottle is formed with a neck defining an opening and a closed bottom distanced therefrom, with a hub of a needleless syringe having a barrel enlarged relative to the hub, the device comprising:

a stopper formed with a passageway therethrough, the stopper being engageable with the opening of the bottle;

a hollow fitting positioned in the passageway, the fitting defining a continuous, open fluid pathway configured for receiving the hub of the needleless syringe, the passageway of the stopper defining a distal wall for closely receiving the fitting therein and a proximal wall radially distanced from the fitting to permit the fitting to expand when the hub of the syringe is engaged therewith; and

a tube having a proximal end in fluid communication with the fluid pathway of the hollow fitting when the hub of the syringe is engaged and disengaged with the hollow fitting and a distal end positionable adjacent the bottom of the bottle.

8. The device of claim 7, wherein the hollow fitting is made of elastic material and defines a fluid pathway therethrough, the fluid pathway having a frusto-conical wall for guiding the hub of the syringe into close engagement with the fitting.

9. The device of claim 8, wherein the neck of the bottle defines a proximal edge, and wherein the closure element includes a cap threadably engageable with the bottle and a stopper having a proximal surface, a distal surface, and a proximal flange, and the proximal flange of the stopper is positioned against the proximal edge of the bottle to establish a fluid seal therebetween when the cap is engaged with the bottle.

10. The device of claim 9, wherein the stopper is formed with a vent passage extending between the proximal and distal surfaces of the stopper.

11. The device of claim 10, wherein the cap is engageable with the bottle when the stopper is positioned in the neck of the bottle.

12. A device for removing liquid from a bottle formed with a neck defining an opening and a bottom distanced from the opening when the bottle is oriented with the bottom below the neck, comprising:

a syringe formed with a hub and a barrel proximal to and radially larger than the hub;

a stopper engaged with the opening of the bottle, the stopper being formed with a fluid passageway therethrough;

a conduit member having a segment positioned in the fluid passageway of the stopper, wherein the conduit member includes a proximal end configured for closely receiving the hub of the syringe and a distal end disposed near the bottom of the bottle;

wherein the passageway of the stopper defines a wall having a distal segment for closely receiving the conduit member therein, the wall further having a proximal segment radially distanced from the conduit member to permit the conduit member to expand when the hub of the syringe is engaged therewith.
