Definitions

• Animal ear tag which has a thorn.
• the invention relates to an animal ear tag which has a mandrel.
• an animal ear tag is worn on the ear of an animal, such as typically a bovine or a pig, and provides information about the subject animal. This information may be provided in the form of human-readable written characters and / or in the form of electronic data stored in the animal ear tag.
• Animal ear tags of the type discussed here include two "outer parts" lying on opposite sides of the animal ear, as well as a spike.
• the two outer parts abut each other on opposite sides of the ear of the animal's ear and are connected by the mandrel, wherein the mandrel passes through a through hole in the auricle.
• the thorn is a slender, elongated part. Usually it is connected to one of the two outer parts before attachment to the animal's ear - e.g. monolithic -, and is hooked to the second outer part when attached to the animal ear.
• An outer portion of the animal ear tag may be either a relatively large plaque, or a housing that includes electronic components, or a combination of both.
• the mandrel For the process of attachment to the animal's ear, the mandrel should be as stiff as possible, otherwise there is a risk that it buckles during the lancing process.
• the thorn should tend to be pliable, as it is more comfortable and healthier for the animal, and the animal ear tag is more flexibly yielding when the animal is grazing on an object with the animal ear tag.
• the writings GB 1485447 A and GB 2066164 A show animal ear tags in which the vast longitudinal portion of the mandrel is formed as open at one end face tube, wherein the opening is at the free end of the mandrel.
• an arrow-shaped, stiff metal pin is inserted into the elongated cavity in the mandrel and thus stiffened the mandrel and provided a sharp point for the penetration through the auricle.
• the metal pin is removed from the mandrel, so that the mandrel is relatively elastic yielding.
• the thorn can adapt to the animal's ear so far that it hardly comes to chafing and further injuries at the through hole of the animal's ear.
• the disadvantage is that the opening of the cavity in the mandrel must pass through that part of the ear tag with which the mandrel is monolithically connected.
• active animal ear tags those are those in which the main body includes a housing with electronic components contained therein and a battery or an accumulator - to space problems, because in these animal ear tags located in the main body space on the mandrel axis for reasons of mass dynamics of other parts should be taken.
• DE 69504644 T2 shows in its Fig. 3 constructed of several parts mandrel an animal ear tag. These parts comprise a plurality of circular cylindrical, hollow parts which are arranged coaxially with each other in the axial direction one behind the other and abut against one another on flat end faces. Through the central axial cavity of all these parts passes through a flexible connecting element made of a soft elastic material.
• the mandrel is thus advantageously stiff relative to pressure in the axial direction and rigid and at the same time advantageously yielding to bending and shearing stress normal to the axial direction.
• the disadvantage is that open gaps remain between the individual circular-cylindrical parts for piercing the animal's ear. These pose a significant health risk to the animal, as they can form and maintain a breeding ground for pathogens.
• the object underlying the invention is an animal ear tag whose pin is stiff and firm at least for the process of attachment to the animal's ear against axial compressive force, but is soft against bending stress to its axis normal lying bending axes, compared to the construction already known - have improved execution.
• the improvement should be that neither a stiffening part is subsequently removed from the mandrel, nor that the outer surface of the mandrel has a collision surface between two parts - and thus a gap -.
• the mandrel has a plurality of longitudinally of the mandrel one behind the other parts of a harder material, and another part of a resiliently softer material, which in the longitudinal direction of the mandrel along several the parts of harder material extends and connects them.
• the parts of harder material be stacked together, and that part which is made of elastically softer material, a shell which comprises a plurality of stacked parts of harder material on the lateral surface of the parts formed by these parts Wrapped in stacks.
• the shell does not adhere to the material of the stacked parts.
• the sheath preferably consists of a material which can be formed by the plastic injection molding process and is formed by encapsulation of the parts stacked against each other.
• Fig.l shows somewhat stylized in side sectional view of an exemplary animal ear tag according to the invention.
• the animal ear tag according to FIG. 1 has a mandrel 1 and the two outer parts 2, 3, which in this example are only simple flat plaques.
• the mandrel 1 which is typically of circular symmetry, has a core 4 of parts 5, 6, 7 of harder material and a shell 8 from compared to the material of the parts 5, 6, 7 significantly soft elastic material.
• the parts 5, 6, 7 made of harder material are stacked together in the longitudinal direction of the core 4.
• stacked together is meant that each two adjacent parts along a stacking direction are moved to mutual contact to each other, wherein at the contact surface at least one elevation on a part 5, 6, 7 in a recess on the second part 5, 6, 7 protrudes, the two parts of surface parts of said survey and said recess abut each other and Relatiwerschiebung the two parts normal to the stacking direction must forcibly with a movement of the two parts in the stacking direction away from each other.
• “Stacked together” means that the parts 5, 6, 7 are pushed together in the stacking direction as far as possible, and in this case lie exactly defined in their relative position to the stacking direction abut each other.
• the angle between the contact surfaces of adjacent parts 5, 6, 7 of harder material and the stacking direction is significantly greater than the angle of friction between the materials of the contacting surfaces.
• no frictional plug connection or wedge connection between the adjacent parts is formed. Such a connection would restrict the desired flexibility of the mandrel 1 too much.
• the parts 5, 6, 7 of harder material together form a kind of arrow, wherein the arrowhead forming part 5 is wider than the adjoining middle parts 6, on which the widened, the arrow end performing part 7, follows.
• the parts 5, 6, 7 of harder material used as a stack in a plastic injection molding tool therein the stack at the front and at the rearmost part 5, 7 fixed and molded with the material of the shell 8.
• the material of the shell is typical usually a rubber-elastic and injection-moldable plastic.
• an antibacterial and antiseptic agent is incorporated in the material of the shell 8 and / or the shell 8 is coated with such an agent.
• the sheath 8 and the central part 6 do not adhere to each other, as this would severely limit the bending flexibility of the mandrel 1. If necessary, adhesion between the shell 8 and the parts 6 can be avoided by coating the lateral surface of the central parts 6 with a release agent prior to encapsulation with the material of the shell 8.
• the shell 8 extends to the foremost part 5 of harder material and the rearmost part 7 of harder material to surface areas of these parts, which are facing away from the middle parts 6 of harder material.
• the shell 8 holds form-fitting against the fact that the parts 5, 6, 7 of harder material in the longitudinal direction of the mandrel 1 can be moved away from each other.
• a resilient bias to train in the shell 8, whereby the shell 8 permanently very fat on the parts 5, 6, 7 made of harder material and adjacent parts 5, 6, 7 of harder material pressed together.
• the sheath 8 does not extend over the foremost part 5 of harder material and on the rearmost part 7 of harder material over the entire surface facing away from the middle parts 6 of harder material.
• the non-covered by the shell surface areas of these parts 5, 7 of harder material which in any case are not in contact with the animal ear when mounted animal ear tag, in the production of the shell 8 for holding the stack of parts 5, 6, 7 harder material by means of a tool available.
• the layer thickness of the sheath 8 is typically between 0.5 and 1 mm.
• the shell 8 can be applied, for example, by painting on the parts 5, 6, 7 of harder material.
• paint and surface pretreatment of the middle parts 6 made of harder material are to be adjusted so that a small but nevertheless existing adhesion occurs between the paint and the parts 6. After curing of the paint, this can then be lifted rather unwanted adhesion by the mandrel 1 is gently bent slightly.
• the britenförmige outer part 2 is monolithically connected to the mandrel 1 formed, to be precise with the shell 8.
• the outer part 2 may be formed in a common injection molding process with the shell 8. In order to be able to form the outer part 2 and the casing 8 nevertheless from different material, two-component injection molding can be used.
• the parts 5, 6, 7 of harder material have one or more openings or grooves which extend in the longitudinal direction or in the transverse direction of the mandrel 1 and which from harder part 5, 6, 7 to harder part 5, 6, 7 are aligned, and these openings are filled with the flexible material from which the shell 8 is formed - typically by injection molding.
• the parts 5, 6, 7 of harder material have one or more openings or grooves which extend in the longitudinal direction or in the transverse direction of the mandrel 1 and which from harder part 5, 6, 7 to harder part 5, 6, 7 are aligned, and these openings are filled with the flexible material from which the shell 8 is formed - typically by injection molding.
