Abstract

For interconnecting a syringe with a barrel and needle to a bottle of medicine wherein the bottle has a generally cylindrical cap with a central target zone of relatively small diameter to be pierced by the needle, wherein the adaptor includes a body having a first end with a truncated cone-shaped mouth converging from the first end and an opposite end with a recess sized to receive the bottle cap, the cone-shaped surface of the mouth being adapted to guide the needle into generally co-axial alignment with the bottle and toward the target zone of the bottle cap.

Claims

1. For use in charging a dose of medicine through the mouth of a medicine bottle into a syringe having an exterior surface and which syringe includes a barrel and needle extending from the barrel,

a medicine bottle cap and a mating tubular adaptor,

said cap being sized and configured to engage the medicine bottle and close the bottle mouth and said cap having a central target zone of relatively small diameter in covering relation of a portion of the bottle mouth,

said target zone comprising pierceable material to be pierced by the needle to withdraw medicine and charge the syringe barrel with a dose of said medicine,

said mating tubular adaptor having a through axial passageway, said adaptor including

a) a first end zone with an outer axially facing surface and defining a recessed skirt portion of said passageway extending axially from said outer axially facing surface and into said first zone, said skirt portion being sized and adapted to receive said bottle cap in said recessed skirt position and comprising means to removably fasten said cap to said adaptor and maintain said adaptor and bottle cap in co-axial alignment,

b) a second end zone with an outer axially facing surface, said second end zone having a single truncated, cone-shaped recessed portion co-axial with said skirt portion, said truncated, cone-shaped recessed portion converging at a substantially constant slope from an enlarged mouth at the outer axially facing surface of said second end zone with said mouth having a diameter greater than said target zone diameter,

c) an intermediate portion between the first and second end zones having a bore interconnecting said cone-shaped recess and said skirt said bore having a diameter substantially equal to said target zone diameter,

d) said cone-shaped surface of said recessed portion defining a needle guide means for the distal end of said needle to guide the distal end of the needle to and through said bore and target zone upon the application of a generally co-axially directed force toward the first end to pierce the central target zone of said cap.

2. A medicine bottle cap and mating tubular adaptor as set forth in claim 1 wherein said adaptor is provided by an annular flange between the outer axially facing surface of said first and second end zones to be gripped by a user to apply axial force to push the adaptor onto a bottle cap or to withdraw the adaptor from a bottle cap.

3. A medicine bottle cap and mating tubular adaptor as set forth in claim 1 wherein the adaptor includes a hingedly connected cap cover with a recess, sized and configured to cover and receive the second end zone and receive the cone-shaped recess defining structure on swinging movement from a normal position.

4. A medicine bottle cap and mating tubular adaptor as set forth in claim 1 wherein the first end zone is internally threaded about the through opening.

5. A medicine bottle cap and mating tubular adaptor as set forth in claim 1 wherein said adaptor is of transparent material.

6. A medicine bottle cap and mating tubular adaptor as set forth in claim 1 wherein the adaptor is transparent and is sized and configured to substantially receive the needle barrel therein between the end faces and the adaptor includes magnifying means to enlarge the image of indicia on the barrel.
