Abstract

An animal ear tag includes a component locking member of novel design. The component locking member has an interior passageway which substantially conforms in shape to the post or pin of an ear tag installation tool to stabilize the connection therebetween which prevents slippage or other undesirable movement of the component locking member when installed on the ear of an animal. The component locking member is characterized by a transverse portion having a pair of opposed flanges, and a substantially planar rear edge. The planar edge is adapted for contact with an inner surface of a jaw of an installation tool which further provides stabilization between the component locking member and the ear tag installation tool. As an ear tag assembly, the invention utilizes the component locking member and an ear tag panel having a grommet which engages the component locking member.

Claims

1. In subcombination, a component locking member for an ear tag comprising:

a shaft extending along a longitudinal axis and having a first end and a second end;

a cutting tip attached to said second end of said shaft for piercing an animal'"'"'s ear; and

a transverse portion attached to said first end of said shaft and extending substantially perpendicular thereto, said traverse portion having a rear edge, and a disk-shaped recess formed in said transverse portion at said rear edge, said disk-shaped recess defined by an inner surface extending substantially parallel to said longitudinal axis and a substantially cylindrical opening communicating with said disk-shaped recess and extending longitudinally within said shaft, said disk-shaped recess having a diameter larger than a diameter of said substantially cylindrical opening, said recess and said opening adapted to receive a post of an ear tag installation tool, said component locking member being made of a unitary one piece construction.

2. A subcombination, as claimed in claim 1, wherein:

said substantially cylindrical opening is tapered in shape to conform to the post of the ear tag installation tool.

3. A subcombination as claimed in claim 1, wherein:

said transverse portion comprises a pair of opposing flanges extending in opposite directions from one another.

4. A subcombination, as claimed in claim 1, wherein:

said transverse portion includes a rear planar surface.

5. A subcombination, as claimed in claim 1, wherein:

said component locking member is made of a substantially homogeneous material.

6. In combination, a component locking member for an ear tag, and a post of an ear tag installation tool comprising:

a shaft extending along a longitudinal axis and having a first end and a second end;

a cutting tip attached to said second end of said shaft for piercing an animal'"'"'s ear;

a transverse portion attached to said first end of said shaft and extending substantially perpendicular thereto, said traverse portion having a rear edge, and a disk-shaped recess formed in said transverse portion at said rear edge, said disk-shaped recess defined by an inner surface extending substantially parallel to said longitudinal axis and a substantially cylindrical opening communicating with said disk-shaped recess and extending longitudinally within said shaft, said disk-shaped recess having a diameter larger than a diameter of said substantially cylindrical opening; and

a post having a cylindrical needle portion, and an integral base portion supporting said needle portion, said base portion including a shoulder defining an exterior edge of said base portion, wherein said post is inserted within said recess and through said opening such that said shoulder of said post makes frictional engagement with said recess.

7. A combination, as claimed in claim 6, wherein:

said substantially cylindrical opening is tapered in shape to conform to said needle portion.

8. A combination, as claimed in claim 6, wherein:

said transverse portion comprises a pair of opposing flanges extending in opposite directions from one another.

9. A combination, as claimed in claim 6, wherein:

said transverse portion includes a rear planar surface.

10. A combination, as claimed in claim 6, wherein:

said component locking member is made of a substantially homogeneous material.

11. An ear tag comprising:

a shaft extending along a longitudinal axis and having a first end and a second end;

a cutting tip attached to said second end of said shaft for piercing an animal'"'"'s ear;

a transverse portion attached to said first end of said shaft and extending substantially perpendicular thereto, said traverse portion having a rear edge, and a disk-shaped recess formed in said transverse portion at said rear edge, said disk-shaped recess defined by an inner surface extending substantially parallel to said longitudinal axis and a substantially cylindrical opening communicating with said disk-shaped recess and extending longitudinally within said shaft, said disk-shaped recess having a diameter larger than a diameter of said substantially cylindrical opening, said recess and said opening adapted to receive a post of an ear tag installation tool said component locking member being made of a unitary one piece construction; and

a panel including a grommet attached thereto, said grommet being adapted for engagement with said cutting tip when the ear tag is installed on an animal'"'"'s ear.

12. An ear tag, as claimed in claim 11, wherein:

said grommet includes an inner rim defining an opening through said grommet, and said cutting tip is inserted through said opening in said grommet and makes frictional engagement with said inner rim while being inserted therethrough.

13. An ear tag, as claimed in claim 12, wherein:

said cutting tip includes a back edge which engages said inner rim preventing said cutting tip from being pulled back through said opening in said grommet.

14. An ear tag, as claimed in claim 11, wherein:

said shaft, said cutting tip, and said transverse portion forming a component locking member, and said component locking member being made of substantially homogeneous material.
