Abstract

The invention comprises an animal identification tag. The tag is a plastic sheet preformed into a sspiral shape to form several overlapping spiral layers from one end to the other. The sheet is formed of resilient material whereby the outer spiral layer may be separated from the next adjacent layer along its outer edge so that a cow's tail of conventional size may be slipped between laterally of the length of the tail and the tag may be rotated to slide the tail between the spiral layers until the tail is located inside the innermost spiral layer. The tag has a preformed spiral shape wherein the innermost spiral layer has a diameter when unstraightened that is slightly smaller than the outside diameter of a small cow's tail so that the tag will compress back, after straightening, toward its smaller diameter and thereby snuggly engage the tail of cows of varying sizes to retain the tag on the tail. The tag has indicia along its outermost spiral layer to identify the cow.

Dependent claims

An animal identification tag for attachment to a cow's tail by spiral encirclement about the cow's tail comprising a resilient sheet resiliently biased in length into a spiral path of overlapping layers of connecting curves circling about a central point in one plane with said curves constantly increasing in size;

said sheet having an innermost end and an outermost end in said spirial;
said sheet having its smallest curve at its innermost end of the spiral and its largest at its outermost end;
said sheet having a length in excess of its circumference and a width in excess of its circumference;
said tag, in its biased position, having its smallest curve smaller in diameter than the outside diameter of the cow's tail with said tag's resilient biasing thereby acting to contract the tag, when the tag is encircled about the cow's tail, toward its position that is smaller than the outside diameter of the cow's tail to frictionally engage the tag about the cow's tail and with said bias having sufficient force to frictionally retain the tag in position on the cow's tail;
said tag having its layers sufficiently separable and straightenable from one another whereby the tail of the cow may be slipped laterally of the length of the tail between the outermost end of the spiral tag and the next adjacent layer and the tag may be rotated relative to the tail to slide the tail along the spiral sheet between the layers until the tail slides out the innermost end of the sheet into the inside of the tag to be spirally encircled by the innermost curved layer of the spiral tag;
indicia along the outside of the outermost layer to identify the cow.
