Abstract

A vial of liquid removably attachable to a syringe. In one embodiment, a luer-loc-tip is integrally mounted to the vial which is removably mountable to a syringe for withdrawing liquid from the vial without the presence of a needle. In an alternate embodiment, the luer-loc flange is mountable to a conventional vial by means of clamps and enclosed by means of a sealing cap.

Claims

1. The combination of:

a vial of liquid including a hollow main body with an outlet, said vial further including openable sealing means extending across said outlet to allow withdrawal of said liquid from said main body, said outlet including first locking means having a luer-loc flange integrally formed thereon; and

,

a hollow casing including a plunger slidably mounted therein, said casing including an inlet and second locking means positioned adjacent said inlet and non-removable therefrom, said inlet connectable with said outlet with said second locking means removable lockable directly to said luer-loc flange of said first locking means to secure said vial to said casing as said plunger is moved away from said inlet withdrawing said liquid from said vial into said casing, said casing further including a needle mountable to said inlet once said vial is removed therefrom.

2. The combination of claim 1 wherein:

said hollow main body includes an outwardly extending first neck forming said outlet and said hollow casing includes a outwardly extending tube slidably connectable with said neck, said first locking means and said second locking means includes an outwardly extending flange on said neck and a groove positioned on said tube which are matable together.

3. The combination of claim 2 wherein:

said hollow casing includes a sleeve concentric with but outwardly of said tube with said tube extendable into said neck which is extendable between said tube and said sleeve.

4. The combination of claim 3 wherein:

said first locking means is formed exteriorly on said neck and said second locking means is formed interiorly on said sleeve.

5. The combination of claim 4 wherein:

said first locking means includes a pair of diametrically opposed and outwardly extending flanges oriented perpendicularly to said neck, said second locking means includes a spiral groove on said sleeve opening toward said tube which slidably receives said flanges to removably lock said vial to said casing.

6. The combination of claim 5 wherein

said main body of said vial and said flanges are integrally secured together and form a unitary and squeezable plastic construction sized to hold a single dose of said liquid.

7. The combination of claim 5 wherein:

said openable sealing means includes a cap removably affixed atop and to said first neck, said cap includes a handle which may grasped to twist off said cap from said first neck exposing said outlet.

8. The combination of claim 5 wherein:

said hollow main body includes a second neck with a passage extending therethrough into said vial, said first neck includes a base seated upon said second neck with said outlet aligned with said passage; and

further comprising;

an inner seal securing said base to said second neck.

9. The combination of claim 8 wherein:

said openable sealing means is mounted and affixed to said second neck and extends upwardly around said second neck and said first neck enclosing both said first neck and said second neck while sealing said outlet.

10. A vial of liquid comprising:

a hollow main body with an outwardly extending first neck forming an outlet, said hollow main body further including openable sealing means extending across said outlet to allow withdrawal of said liquid from said main body, said neck includes mounting adapter means thereon including first locking means with an outwardly extending flange formed exteriorly thereon,

said mounting adapter means further including a base and a luer-loc flange joined together by said neck, said first locking means located on said luer-loc flange and includes a pair of diametrically opposed and outwardly extending flanges oriented perpendicularly to said neck,

said hollow main body further including a second neck with a passage extending therethrough into said hollow main body, said base seated upon said second neck with said outlet aligned with said passage, and further comprising an inner seal securing said base to said second neck.

11. The vial of claim 10 wherein:

said openable sealing means is mounted and affixed to said second neck and extends upwardly around said second neck and said first neck enclosing both said first neck and said second neck while sealing said outlet.

12. A syringe-vial device comprising:

a vial of liquid with said vial having a luer-loc flange integrally formed thereon;

a cylindrical shaped casing with a first end having a tube forming a passage into said casing and further having a sleeve thereon to receive said vial with said sleeve concentrically located outwardly of said tube, said first end of said casing connected to a syringe needle once said vial is removed therefrom; and

,

a plunger slidable mounted in said casing to withdraw liquid from said vial through said passage into said casing.

15. The device of claim 16 wherein:

said tube and said sleeve define a annular cavity which opens outwardly from said stop surface against which said vial is held securely against by said thread.

13. The device of claim 14 wherein:

said sleeve includes an inner surface facing said tube with a thread formed thereon defining a groove to receive said vial.

14. The device of claim 15 wherein:

said casing includes a stop surface, said tube extends outwardly from said stop surface a distance greater than said sleeve.
