The present utility model refers to an ore tag. ja to mark animals.

A known form of ear tag for marking animals comprises a male component and a female component, both of which are formed of an elastic plastic material. The male component includes a rod, whose free end has. · A head portion This head portion may include □ it may be formed by an element of hard material. £ 1 ..

Take hold of the drill and engage positively with the hard material. **** • · · · · · ·

The female component includes an opening, which is of a * díá · γ · meter similar to that of the stem. Preferably, a hollow, cylindrical wall or prominence is formed as a page of the female component and is concentric to the opening.

To adjust the tag on an animal ear, the ele- ment of hard material is forced through the ear of the applicator through the ear and the opening in the female component, so that the head portion is located within the limited area. by the prominence or cylindrical wall.

The two components are closed together by the shoulder gear formed by the material area, which surrounds the opening of the female component and a shoulder formed by the head portion of the male component.

Preferably the hollow cylindrical prominence is closed at the opposite end to the aforementioned opening, through which the head portion of the male component is inserted. This closure of the prominence prevents access to the head portion for the purpose of t.

In the following, a more detailed description of the ear tag according to the present utility model will be made. • · · · &lt;

Figure 3 is a view in elevation of another embodiment of the female component of the ear tag.

Figure 4 is a sectional side view of the female component shown in Figure 3.

The ear tag of the present utility model is illustrated. In the drawings, it is like a two-piece tag, having a male component 1 and a female component 12. The male component 1 is formed by a panel 2, from which a rod 4 extends. A head portion 6 is formed at the end of the rod 4 and this forms a shoulder 8 projecting externally. Preferably, the panel 2, the shank 4 and a portion of the head portion 6 are molded in30.

-It is theoretically an elastic plastic material, such as polyurethane. In the preferred form, an element or tip 10 of hard material, plastic or metal, is molded with the head portion and a conical head is thus formed. The stem 4 is hollow, in such a way that a rigid spigot of ...

an applicator tool can be engaged in the stem *. . * ·· · ·· to positively position the hard end 10.

The female component 12 is formed with a panel 14 having the shape shown in Fig. 1 or Fig. 3 or any other suitable form. Panel 14 includes a bee?

. · · Of the shank 4. In the preferred form of the utili model, d.ad • · · the diameters of the opening 16 and the shank 4 are such * '*. · - · · · · that the clearance is sufficient to allow Turn the valve inside the opening. A protrusion 18 is located over the opening 16 and is of a substantially cylindrical shape. The protrusion 18 is closed at one end by a cover 20 located at the opposite end of the protrusion to that of the aperture 16. The protrusion 18 provides a substantially cylindrical cavity 22, which opens outwardly only through the aperture 16. .

The diameter of the cavity 22 is larger than the opening 16 and, in effect, has a diameter that is significantly greater than the maximum cross-sectional diameter of the conical head portion 6 of the male component. The area of ​​material around the opening 16 forms an annular shoulder 24, which is capable of forming a rigid support sufficient to hold the collar 26 within the cavity 22.

The collar 26, substantially cylindrical, is located away from the cavity 22 as illustrated in FIG. 2, and the diameter of the collar 26, when the head portion 6 is located inside the collar, is preferably smaller than that of the cavity. 22, The collar 26 is provided at its lower end with an inner edge 30, which forms an abutment 32, having a diameter that is smaller than the diameter ... of the stem 4 of the female component.

The cylindrical cavity 22, the collar 26 and the coaxial opening 16 sqh \ • · · ·. The collar 26 is preferably expandable and to this end it is slit longitudinally. In the re- laced or initial form of the collar 26, to the inner diameter of co ..

Therefore, when the head • * · the male component is passed through the aberlb * ra 16 and aperture 32 of collar 26, so that is placed within the collar 26 the base 7 of head 6 does expand the collar 26 so that collects a diameter ma yor than their initial diameter. Therefore, the head portion 6 of the male component is firmly held within the collar 26. In addition it is preferred that the interference between the stem and the opening 32 ensures that the stem sa firmly grasps the edge of the collar. With the head portion 6 inside the collar the outer diameter of the collar is still smaller than the inner cavity 22, such that the collar can rotate therein.

With the ear tag so assembled the head 6 of the male nenta compo-71 is maintained within the collar 26 and can only be withdrawn by considerable pulling force applied to the rod. This tensile force is preferably greater

10 or 35 dN and such pulling force usually results in the head 6 disengaging from the rod 4. As a result of

sequence, the head remains inside the cavity 22 dajft. * · · · · Result that the female or male component is damaged so that none of them can be reused • • • •

The collar 26 is made of a rigid material, which may be a plastic material, such as polyamide with or without fiber refining, such as fiberglass. Alternatively, • • • • • • • the collar 26 can be made of a metal material te · ·. · · · · Having good elastic characteristics. The collar is thus made of a material that only softens at a relatively high temperature and is at a temperature that is clearly higher than the softening temperature of the elastic plastic material, which forms the female component. This relatively high temperature is one that would not normally be reached in the ambient atmosphere.

The collar 26 also has a deformation coefficient under stress, which is higher than that of the material used for the female component. Accordingly, an accidental or voluntary temperature increase, capable of softening the prominence 18, would not modify the shape of the collar 26.

The collar will thus reinforce the prominence 18 and will retain its shape. In order to destroy the bond between collar 26 and prominence 18 it would, therefore, be necessary to completely damage the prominence. Such damage, however, would be observable and then the ear tag would be prevented from being used again.

The fully closed prominence 18 ensures that the closure 20 prevents disconnection of the male component from the female component, using an applicator tool inversely. As a result, the ear tag, according to the present utility model, can not be dismantled without being damaged and thus constitutes a tag practically. '· · · · · You proof of fraud.

Preferably the axial length of the collar 26 is smaller than that of the cavity 22 and, therefore, the collar is allowed to slide into the cavity. The slit 34 in • • • • • the collar 26 is sufficiently wide to allow that ..

• • • • • • • the collar is compacted, so that its diameter exteripj? , v '* · can be reduced sufficiently to make it possible for βϊ "i. · · · · • * collar to be inserted into the cavity 22 through the ** * opening 16.

This means that the female component can be molded and the collar inserted afterwards, of the molding. The material, of which the collar is made, has an elastic memory sufficient for it to retain its initial shape once it is inside the cavity. The collar thus opens towards the interior of the cavity, thereby preventing it from separating. This elasticity also facilitates the insertion of the head portion 6 through the opening 32 of smaller diameter and the rigid locking of the head against the inner edge 30 supported by the shoulder 24 of the female component. The presence of the collar of hard material within the prominence also allows the prominence to be molded with the thin wall section. But nevertheless,

This transition portion 37 is located in what may be termed a portion of the component, in which the sides 38 of the portion 36 curve smoothly toward the transition with the main portion 35 of the component. panel. This construction results in the reduction of stress concentrations in the neck portion due to curved side edges 38, while allowing the rising portion 36 to be formed with a greater cross-sectional thickness than the panel portion 35, thereby increasing the force of the ascending portion 36.
