Ear tag for identification of an animal, comprising a deformable element for accomodating a pin
In a tag for identifying and marking animals, the tag associates a receiver button ( 1 ) by irreversible fitting of a finger ( 2 ). The button ( 1 ) includes a head ( 13 ) wherein is provided a cavity ( 8 ) for receiving a punch ( 3 ) of the finger ( 2 ). The head ( 13 ) is secured to a shell ( 5 ) retaining the punch ( 3 ) which is provided with an opening ( 6 ) for introducing the punch ( 3 ) inside the button ( 1 ). The axial wall ( 7 ) of the retaining shell ( 5 ) delimiting the opening ( 6 ) is radially deformable. A chamber ( 11 ) is arranged between the head ( 13 ) and the axial wall ( 7 ) for receiving the latter ( 7 ) deformed under the effect of the punch ( 3 ) passing through the opening ( 6 ).
1. An ear tag for the identification and the tagging of animals:
wherein this tag primarily combines a receiving button ( 1 ) by irreversible interlocking of a pin ( 2 );
wherein this button ( 1 ) comprises a rigid head ( 13 ) inside of which is located a cavity ( 8 ) for axial accommodation of a punch ( 3 ) of the pin ( 2 ), the head ( 13 ) being formed of a hard first material;
wherein this head ( 13 ) is secured to a holding shell ( 5 ) only via a connecting shell ( 14 ) that is secured to both the holding shell ( 5 ) and the head ( 13 ) for holding the punch ( 3 ), which is equipped with an opening ( 6 ) for inserting the punch ( 3 ) inside the button ( 1 ) toward the cavity ( 8 ), and a shoulder ( 10 ) for holding the punch ( 3 ) against the withdrawal of the punch ( 3 ) outside of the button ( 1 ), by stopping a shoulder ( 9 ) that the punch ( 3 ) comprises against the holding shoulder ( 10 ), the holding shell ( 5 ) being made of a flexible second material, the first material and the second material being formed from different materials, the first material being harder than the second material relative to each other;
wherein an axial wall ( 7 ), of the holding shell ( 5 ) that delimits said opening ( 6 ) is formed of an elastic material and is radially deformable to allow passage of the punch ( 3 ) through the opening ( 6 ); and
wherein at least one chamber ( 11 ) is located between the head ( 13 ) and said axial wall ( 7 ) for the accommodation of the axial wall ( 7 ) that is deformed under the action of the passage of the punch ( 3 ) through said opening ( 6 ).
2. The ear tag according to claim 1 , wherein the chamber ( 11 ) is radially subdivided into a number of basic chambers.
3. The ear tag according to claim 2 , wherein the holding shell ( 5 ) comprises elements ( 17 ) for centering the head ( 13 ), and wherein the basic chambers are separated from one another by radial partitions that also constitute said centering elements ( 17 ).
4. The ear tag according to claim 3 , wherein said centering elements ( 17 ) consist of lugs located on the outside periphery of said axial wall ( 7 ) of the holding shell ( 5 ), which constitute crosspieces between the axial wall ( 7 ) and the peripheral wall ( 15 ), locating said chamber ( 11 ) between them.
5. The ear tag according to claim 2 , wherein said axial wall ( 7 ) of the holding shell ( 5 ) is continuous, and its constituent material is an elastically deformable plastic material.
6. The ear tag according to claim 1 , wherein the connecting shell ( 14 ) is inserted by molding jointly on the head ( 13 ) and on the holding shell ( 5 ).
7. The ear tag according to claim 6 , wherein the head ( 13 ) comprises a full peripheral wall ( 15 ) that is inserted between the connecting shell ( 14 ) and said chamber ( 11 ) to protect the chamber ( 11 ) against intrusion of the constituent material of the connecting shell ( 14 ) during the molding operation of the connecting shell ( 14 ).
8. The ear tag according to claim 7 , wherein the chamber ( 11 ) is located between the full peripheral wall ( 15 ) of the head ( 13 ) and said axial wall ( 7 ) of the holding shell ( 5 ).
9. The ear tag according to claim 7 , wherein the holding shell ( 5 ) comprises elements ( 17 ) for centering the head ( 13 ).
10. The ear tag according to claim 7 , wherein said axial wall ( 7 ) of the holding shell ( 5 ) is continuous, and its constituent material is an elastically deformable plastic material.
11. The ear tag according to claim 6 , wherein the holding shell ( 5 ) comprises elements ( 17 ) for centering the head ( 13 ).
12. The ear tag according to claim 11 , wherein said centering elements ( 17 ) consist of lugs located on the outside periphery of said axial wall ( 7 ) of the holding shell ( 5 ), which constitute crosspieces between the axial wall ( 7 ) and the peripheral wall ( 15 ), locating said chamber ( 11 ) between them.
13. The ear tag according to claim 11 , wherein said axial wall ( 7 ) of the holding shell ( 5 ) is continuous, and its constituent material is an elastically deformable plastic material.
14. The ear tag according to claim 6 , wherein said axial wall ( 7 ) of the holding shell ( 5 ) is continuous, and its constituent material is an elastically deformable plastic material.
15. The ear tag according to claim 1 , wherein said axial wall ( 7 ) of the holding shell ( 5 ) is continuous, and its constituent material is an elastically deformable plastic material.
16. The ear tags according to claim 1 , wherein it is equipped with electronic identification means.
17. The ear tag according to claim 1 , wherein said axial wall ( 7 ) of the holding shell ( 5 ) is continuous, and its constituent material is an elastically deformable plastic material.
18. The ear tag according to claim 1 , wherein a top surface of the axial wall is adjacent to a bottom surface of the holding shell.
19. The ear tag according to claim 1 , wherein the first material is metal, a hard plastic material or polyamide.
20. The ear tag according to claim 1 , wherein the second material is a flexible plastic material or polyurethane.
