Abstract

An improved identification marker and method of assembling the marker is provided, which includes the steps of providing a glass vial and filling the glass vial with a quick curing liquid to a predetermined volume corresponding to at least the volume wherein the unfilled volume of the vial is equal to the displacement volume of an IC circuit hybrid and antenna. The IC circuit hybrid and antenna are placed in the vial so as to be entirely enveloped by the liquid. A cap is placed on the vial and the liquid is cured. Preferably, the cap is an anti-migration cap so that when the transponder is implanted in an animal, it prevents the transponder from sliding out.

Claims

1. A method of producing an identification marker formed from a vial, the method comprising the steps of:

providing a vial having an open end and having an outer wall and an inner wall;

partially filling the vial with a predetermined volume of curable material in a liquid state;

inserting an electronic transponder into the vial containing the curable material, wherein the insertion of the electronic transponder results in the curable material completely enveloping the transponder;

affixing a cap over the open end of the vial;

curing the curable material; and

assuring that the curable liquid material sufficiently fills the vial so that when the electronic transponder is inserted into the vial, the curable liquid material overflows the open end and covers, at least in part, the outer wall of the vial at the open end so that curing causes the curable liquid material disposed between the cap and the outer wall of the vial to bond the cap to the vial.

2. The method of claim 1, wherein the vial is a glass vial and further comprising the step of exposing the glass vial having the cap placed on the open end of the glass vial to UV irradiation for sufficient amount of time to solidify the UV curable material.

3. The method of claim 1, wherein the predetermined volume is at least as great as the volume of the vial minus the displacement volume of the transponder.

4. The method of claim 1, wherein the curable material comprises a UV curable polyvinyl chloride adhesive.

5. The method of claim 1, wherein the cap is an anti-migration cap which provides a smooth radius, when placed on top of the open end of the glass vial.

6. The method of claim 4, wherein the vial and the cap are bio-compatible.

7. The method of claim 1, wherein the transponder comprises an IC circuit hybrid assembly and an antenna coil.

8. The method of claim 1, wherein the transponder is programmable and capable of sensing the temperature of an animal.

9. The method of claim 1, wherein the cap is an antimigration cap.

10. A method of producing an identification marker formed from a vial, the method comprising the steps of:

providing a vial having an open end and having an outer wall and an inner wall;

partially filling the vial with a predetermined volume of curable material in a liquid state;

inserting an electronic transponder into the vial containing the curable material, wherein the insertion of the electronic transponder results in the curable material completely enveloping the transponder;

applying a glue to the vial to affix the cap to the vial;

affixing a cap over the open end of the vial; and

curing the curable material;

wherein the predetermined volume is such that insertion of the transponder causes the curable material to spill out and run over the outer wall of the vial, so that the curable material will be disposed between the outer wall and the cap when the cap is affixed over the open end of the vial.
