Claim 7

A tag, as claimed in claim 4, wherein at least one of said portions is hollow, said tag further including: insecticide containing means in said hollow portion; and conduit means .[.in.]. .Iadd.extending longitudinally along .Iaddend.said shaft for transmitting insecticide from said insecticide containing means to the opening .Iadd.where said smaller ends of said conical portions come together.Iaddend..

Claim 8

A tag as claimed in claim 5, wherein said conduit means comprises: a plurality of longitudinally-extending, circumferentially-spaced grooves in the outer periphery of said shaft .Iadd.extending from said insecticide containing means to said smaller ends of said conical portions.Iaddend..

Claim 9

An identification tag for animals that is installed in an opening cut through the skin tissue of the animal wherein the tag enhances healing of the opening and will shed obstructions, said tag comprising: a pair of separable tapered portions, each having a larger end and a smaller end formed as a solid of revolution .Iadd.having an included angle not exceeding 90°.Iaddend.; means joining said smaller ends of said portions through said opening, the taper of said portions causing them to be spaced at an angle to the skin tissue and allowing air to reach the edges of said opening all around its periphery to promote rapid healing and causing them to shed any obstacle coming into contact with said portions .Iadd.by pivoting in the opening so that the surface engaged by the obstacle is at an obtuse angle to the skin.Iaddend..

Claim 10

An identification tag for animals that is installed in an opening cut through the skin tissue of the animal wherein the tag enhances healing of the opening and will shed obstructions, said tag comprising: a pair of separable tapered portions, each having a larger end and a smaller end formed as a solid of revolution .Iadd.having an included angle not exceeding 90°.Iaddend.; means joining said smaller ends of said portions through said opening, the taper of said portions causing them to be spaced at an angle to the skin tissue and allowing air to reach the edges of said opening all around its periphery to promote rapid healing and causing them to shed any obstacle coming into contact with said portions .Iadd.by pivoting in the opening so that the surface engaged by the obstacle is at an obtuse angle to the skin.Iaddend..

Claim 11

An identification tag for animals .[.that is installed.]. .Iadd.for installation .Iaddend.in an opening cut through the skin tissue of the animal wherein the tag enhances healing of the opening and will shed obstacles, said tag comprising: a body having an hourglass configuration wherein the neck of the configuration is positionable in the opening, said configuration being separable into two halves.Iadd., each half having a surface of revolution whose cross-section has an included angle not exceeding 90°.Iaddend.; and means for connecting said two halves together wherein the configuration of each half extends away from the skin tissue .[.at an angle thereto.]. to facilitate healing of the opening and to shed obstacles coming into contact .[.therewith.]. .Iadd.with said surface by pivoting in the opening so that the surface is at an obtuse angle to the skin.Iaddend..

Claim 12
