International Classification:

G09F 314

US Classification:

40301

Abstract:

An animal tag system for easily securing a tag upon an animal's ear by piercing the ear for reducing the chance of infection and removal. The tag system includes a tag member having a broad portion and a narrow portion, an extended member extending from the narrow portion, and a tip member attached orthogonally to the extended member opposite of the tag member wherein the tip member is insertable into the ear of an animal. The tip member is comprised of a shaft member having a spiked end and open end exposing a center bore within. The tip member further includes a flanged portion about the spiked end for expanding the hole pierced into the ear by the spiked end thereby allowing the extended member and the tip member to pass through in a substantially parallel position. The tip member becomes orthogonal to the extended member after insertion thereby preventing removal of the tag from the ear through the pierced opening within the ear of the animal.
