Abstract
A livestock tag locking system device, including a male component (1) and a female component (8), wherein the male component (1) has a face (3) onto which indicia may be applied and a stem (4) equipped with a tip (5). The stem (4) is made of a relatively soft plastic material and the tip (5) is made of a relatively hard plastic material. The female component has a cup portion (11) equipped with a retaining ring (14). The cup portion (11) is made of a relatively soft plastic material and the retaining ring (14) is made of a relatively hard plastic material.
Claims8
A female component of a tamper proof livestock ear tag device for receiving a corresponding male component to be inserted therein, the female component comprising:
- an eye portion, said eye portion being equipped with a retaining ring, said eye portion being made of a first plastic material and said retaining ring being made of a second plastic material, said retaining ring being harder than said eye portion, said retaining ring being molded into said eye portion and being at least partially encased by the material of said eye portion, said retaining ring having a ring portion, said ring portion being radially bendable, so that said ring portion is bent towards a radially external material of said eye portion when a tip of said corresponding male component is pressed through said retaining ring, said female component further comprising a cup portion made integrally with said eye portion, said cup portion having a central bore and being formed for receiving at an interior portion said tip of said corresponding male component to be inserted therein and said cup portion being formed so as to define a closed circumferential surface, and wherein said retaining ring has projections, said projections extending in a direction generally orthogonal to the body of the retaining ring and positioning the retaining ring in a predetermined position in the eye portion during molding of the eye portion.
A female component of a tamper proof livestock ear tag device for receiving a corresponding male component to be inserted therein, the female component comprising:
- an eye portion equipped with a retaining ring having a central opening, the eye portion being made of a first plastic material and the retaining ring being made of a second plastic material, the first plastic material being harder than the second plastic material, the retaining ring being molded into the eye portion and being at least partially encased by the first plastic material, the retaining ring having a ring portion being radially bendable;
- the female component further comprising a cup portion made integrally with the eye portion and the cup portion being formed as to define a closed circumferential surface;
- wherein, the cup portion is formed for receiving at an interior portion a tip of the corresponding male component to be inserted therein so that the ring portion is bent towards a radially external material of the eye portion when the tip of the corresponding male component is pressed through the retaining ring, and wherein, if the tip of the corresponding male component to be inserted within the cup portion is broken therein, the ring portion of the female component prevents the broken tip from being removed from within the cup portion and thereby renders the female component unusable for its intended tamper proof function;
- the retaining ring having projections, extending in a direction generally orthogonal to the body of the retaining ring and positioning the retaining ring in a predetermined position in the eye portion during molding of the eye portion.
