Abstract
Abstract A locking insert for a two-component animal ear tag, such as an identification tag or an insecticide tag which uses a flexible, resilient plastic for insecticide or other pest-controlling active ingredient, includes a hollow cylindrical part, a flexible locking ring which is convexly deformed to grasp and resist withdrawal of the male tag component, and an outer flange. The locking insert is positioned in a female tag body component prior to insertion of the male tag component.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
230 words
A female tag component for a two-component animal tag to be attached to an ear or the like of an animal, comprising (a) a tag body component; (b) a generally cylindrical boss on said body component defining a well having an inside diameter, the boss and body component constituting a first integral piece of plastic material; and (c) an aperture in the body component at the base of the well; and said tag component further comprising (d) a unitary locking insert positioned in the well portion, the locking insert comprising (i) a hollow cylindrical portion having an outside diameter substantially equal to the inside diameter of the well, the length of the hollow cylindrical portion of the locking insert being substantially equal to the length of the well in the cylindrical boss on the tag body component; (ii) an inwardly projecting flexible locking ring at one end of the cylindrical portion; and (iii) an outer flange portion adjacent the end of the hollow cylindrical portion projecting outward and having an outside diameter greater than the inside diameter of the well; the locking insert being constructed of a material which permits the flexible locking ring to be convexly deformed when a male tag component is passed therethrough, and having a limit of elasticity which permits it to maintain its convexly deformed shape, whereby to resist withdrawal of the male tag component.
Claim 2
Dependent Claim
230 words
A female tag component for a two-component animal tag to be attached to an ear or the like of an animal, comprising (a) a tag body component; (b) a generally cylindrical boss on said body component defining a well having an inside diameter, the boss and body component constituting a first integral piece of plastic material; and (c) an aperture in the body component at the base of the well; and said tag component further comprising (d) a unitary locking insert positioned in the well portion, the locking insert comprising (i) a hollow cylindrical portion having an outside diameter substantially equal to the inside diameter of the well, the length of the hollow cylindrical portion of the locking insert being substantially equal to the length of the well in the cylindrical boss on the tag body component; (ii) an inwardly projecting flexible locking ring at one end of the cylindrical portion; and (iii) an outer flange portion adjacent the end of the hollow cylindrical portion projecting outward and having an outside diameter greater than the inside diameter of the well; the locking insert being constructed of a material which permits the flexible locking ring to be convexly deformed when a male tag component is passed therethrough, and having a limit of elasticity which permits it to maintain its convexly deformed shape, whereby to resist withdrawal of the male tag component.
Claim 3
Dependent Claim
33 words
A component according to claim 1, wherein the outside diameter of the hollow cylindrical portion of the locking insert is tapered between 1° and 2°, having a larger diameter adjacent the outer flange.
Claim 4
Dependent Claim
33 words
A component according to claim 1, wherein the outside diameter of the outer flange portion of the locking insert is substantially equal to the outside diameter of the outer end of the boss.
Claim 5
Dependent Claim
21 words
A component according to one of claims 1-3, wherein the first integral piece of plastic material contains a pest-controlling active ingredient.
Claim 6
Dependent Claim
32 words
A component according to one of claims 1-3, wherein the first integral piece of plastic material is laminated from a softer piece containing insecticide bonded to a second piece of tougher material.
Claim 7
Dependent Claim
41 words
A component according to one of claims 1-3, wherein the insert is a plastic material having a tensile strength above 7,000 psi, a flexural modulus between 2.25×10 5 and 4×10 5 psi and an elongation at yield between 5% and 12%.
Claim 8
Dependent Claim
24 words
A component according to claim 6, wherein the insert is made from a material selected from the group consisting of polyurethane, nylon-6 and acetal.
Claim 9
Dependent Claim
96 words
A two-compartment ear tag assembly comprising (1) a female tag component according to one of claims 1-3, the tag body component constituting the first integral piece of plastic material being manufactured of soft, resilient plastic material; and (2) a male tag component, adapted for insertion through the aperture at the base of the well and into the well, the male tag component comprising (a) a tapered cylindrical stem; (b) a flange at one end of the tapered cylindrical stem; and (c) a pointed end portion having a maximum diameter greater than the diameter of the stem.
Claim 10
Dependent Claim
51 words
A two-component ear tag assembly according to claim 8, wherein the maximum diameter of the pointed end portion is substantially equal to the inside diameter of the hollow cylindrical portion of the insert and larger than the inside diameter of the aperture in the flexible inner flange portion of the insert.
Claim 11
Dependent Claim
30 words
A two-component ear tag assembly according to claim 8 wherein the narrowest diameter of the tapered stem is no larger than the inside diameter of the convexly deformed locking ring.
Claim 12
Dependent Claim
29 words
A two-component ear tag assembly according to claim 8, wherein the pointed end portion comprises a tip of material selected from the group consisting of metal and hard plastic.
