Definitions

  • the invention relates to an ear tag element for an ear tag for marking animals, which ear tag element comprises a body and a transponder accommodated in the said body, the transponder • comprising a chip and an antenna which are connected to one another, and the body of the ear tag element being made from flexible material.
  • EP 0 639 942 describes an ear tag element having a transponder as used for an ear tag for marking animals.
  • the antenna and the chip of the transponder are arranged in a rigid housing, for example made from polycarbonate, which housing protects the chip and the antenna.
  • the housing is embedded by injection moulding in the body of the ear tag element, which is made from a flexible material, such as polyurethane .
  • the known ear tag may have disadvantageous effects on the animal wearing the ear tags.
  • the object of the invention is to provide an improved ear tag element.
  • a further object of the invention is to provide alternative production methods .
  • the invention achieves the object by means of an ear tag element according to claim 1.
  • the ear tag element according to the invention is designed in such a way that the body of the ear tag element permits elastic deformation at the location of the transponder, and the transponder can be deformed with the body of the ear tag element on account of the absence of a rigid housing around the transponder or a rigid carrier to which the transponder is secured.
  • This is advantageous, for example, if an animal which has become trapped in a fence, for example, is attempting to free itself.
  • the ear tag element according to the invention can therefore be deformed even at the location of the transponder if it is subjected to a mechanical load as a result of the animal attempting to free itself. This will make it easier for the animal to disentangle itself, and the risk of the ear to which the ear tag element is fitted tearing open is considerably reduced compared to when using known ear tags.
  • Transponders which are used in ear tags usually comprise an antenna made from thin metal wire (usually designed as a flat annular coil) and a chip which is of limited size compared to the antenna.
  • the antenna can be elastically deformed, and on account of its limited size the chip does not impair the flexibility of the transponder as a whole.
  • the chip is generally smaller than 5 ⁇ 5 mm.
  • the transponder is secured to a carrier made from a flexible material, preferably a flexible plastic.
  • This carrier has no adverse effect on the elastic deformability of the ear tag element.
  • the carrier is a sheath which surrounds the transponder.
  • the transponder is preferably then enclosed between two layers of plastic film, with the two layers of film being joined to one another in such a manner that in the intended use the transponder is sufficiently protected from unfavourable influences from the environment, such as moisture and dirt, without the transmission of signals between transponder and receiver being impeded.
  • Polyester film is a suitable material for the sheath, in particular if it is used in combination with an ear tag element body made from polyurethane.
  • the body of the ear tag element will generally be moulded around a prefabricated assembly made up of transponder and sheath. If polyurethane is used for the body of the ear tag element, the processing temperature of the polyurethane during injection moulding is around 230°C. Polyester film is able to withstand short thermal loading at more than 200°C of this nature, and consequently the sheath is not detrimentally affected by the high temperature during the injection moulding of the body of the ear tag element .
  • the transponder As an alternative to using plastic film as material for the sheath, it is possible for the transponder to be moulded into a deformable plastic.
  • the thickness of the assembly made up of the carrier and the transponder is preferably between 0.3 and 0.9 mm.
  • the assembly made up of carrier and transponder is preferably not joined or is only locally joined at a few positions to the body of the ear tag element. This allows the surface of the assembly made up of carrier and transponder to move at least at a micro level with respect to the wall of the recess in the body of the ear tag element, so that the resistance of the ear tag element to deformation is lower than if the assembly made up of carrier and transponder were to be attached to the surface of the body of the ear tag element at least over a considerable part of its outer surface.
  • the assembly made up of carrier and transponder it is preferable for the assembly made up of carrier and transponder to be completely surrounded by the body of the ear tag element.
  • the ear tag element according to the first embodiment of the invention can be produced in a suitable way by the method according to claim 15.
  • an assembly made up of a transponder and a carrier is produced, around which assembly the body of the ear tag element is formed by moulding, for example injection moulding.
  • One or more through-holes are formed in that part of the carrier which extends outside the transponder.
  • the pins are removed prior to the injection moulding of the second part of the body of the ear tag element. Consequently, material does flow through the holes during the injection moulding of this second part.
  • This material therefore forms anchors which are formed on the second part and anchor the 1 assembly made up of carrier and transponder. It is preferable for the material types of the first and second parts of the body of the ear tag element to be so close that bonding occurs between the end of each anchor and the first part of the body of the ear tag element.
  • This method has the advantage that the assembly made up of transponder and carrier is locked in a simple manner in the body of the ear tag element.
  • the transponder comprises only an antenna and a chip, which are connected to one another.
  • the antenna and the chip are directly embedded in the body of the ear tag element; therefore, there is no housing around the antenna and the chip. This has the advantage that there is no need to fit a separate housing or carrier around or against the transponder.
  • the second embodiment is also suitable for ear tag elements in which transponders of a relatively great thickness, for example between 1 and 2.5 mm, are used.
  • the body of the ear tag element prefferably has a first part and a second part, in which case the first part has a recess for receiving the antenna and the chip of the transponder.
  • the second part then ensures that the transponder is protected from dirt and moisture, for example.
  • An ear tag element of this type is simple to produce.
  • the recess in the first part is larger than the antenna and the chip of the transponder.
  • the second part in which the transponder is received at least partially fills the recess.
  • bonding In at least part of the region in which there is contact between the wall of the recess in the first part and the second part of the body of the ear tag element, it is preferable for bonding to occur between the two parts of the body of the ear tag element.
  • This bonding is preferably such that it is impossible for any dirt to penetrate between the two parts of the body of the ear tag element. This can be realized by ensuring that good bonding occurs along the entire periphery of the region in which there is contact between the second part and the wall of the recess in the first part.
  • the second part it is preferable for the second part to completely fill the recess in the first part, so that the ear tag element acquires a smooth outer surface. This helps to prevent the ear tag element from becoming dirty.
  • the first part comprises one or more projections which extend into the recess. These projections support the transponder so that the transponder does not bear directly against the base of the recess.
  • the material of the second part preferably corresponds at least to a certain extent to the material of the first part. It is preferable for both parts to be made from polyurethane.
  • the first variant of the second embodiment can be produced in a suitable way by means of the method according to claim 19.
  • the transponder which comprises an antenna and a chip, is placed in the recess in the finished first part. This preferably takes place outside the injection-moulding machine. After the transponder has been put in place, the recess is covered by a layer of flexible material which thereby forms the second part of the body of the transponder. This method allows simple production.
  • the material of the second part of the body of the ear tag element prefferably be mouldable.
  • the recess in the first part of the body of the ear tag element adjoins the antenna and the chip of the transponder. Those surfaces of the antenna and the chip which do not bear against the wall of the recess in the first part in this variant bear against the second part of the body of the ear tag element.
  • This variant is eminently suitable for production by injection moulding.
  • the material of the second part preferably corresponds at least to a certain extent to the material of the first part. It is preferable for both parts to be made from polyurethane.
  • the second variant of the second embodiment can be produced in a suitable way of means of the method described in claim 22.
  • first of all the antenna and the chip of the transponder are placed in an injection mould, preferably against the wall of the mould cavity in which the first part of the body of the ear tag will be formed.
  • the material will flow around the antenna and the transponder, so that the recess in the first part adjoins the chip and the antenna of the transponder.
  • This method can also be used to produce ear tag elements in accordance with the second variant of the second embodiment in large numbers in a simple and reliable way.
  • ear tags for marking animals comprise a male element, which has a pin that is fitted through an ear of the animal which is to be marked.
  • ear tags of this type comprise a female element which has an opening which is fitted onto the pin of the male element, in such a manner that the ear of the animal is located between the male element and the female element of the ear tag.
  • the two parts are shaped in such a way that the ear tag is locked after the female element has been fitted.
