DETAILED DESCRIPTION

[0038] With reference to FIG. 2 a device to tag an animal according to the present invention is schematically represented and globally indicated with 1. The device 1 include a male 40 and a female 20 with a case 21, adapted to receive a head of the male and to hold it in the case 21. The male and/or the female may carry visual information, for instance a label with a serial number or a bar code, and/or electronic information, for instance stored in a memory of an embedded chip.

[0039] For applying the devices to the animal, an ear of the animal is interposed between the female 20 and the head of the male 40; the head is pressed against the ear and enters the case, piercing the ear of the animal.

[0040] The female is for example in flexible or resilient material and includes the case 21 with a top aperture 26 and a bottom aperture 24. A tamperproof flange 25 is associated to the top aperture and is adapted to let the head of the male enter the case but not to exit from it. For instance, the flange includes flexible tabs inclined towards the inner of the case 21 and adapted to be distanced through the head of the male and to let it enter the case 21, when the male is applied to the female, and to close the head in the case, returning closer. If a force is applied to extract the male from the case (from the top opening), either the tabs brake or the male tip breaks. Thus, the flange is a tamperproof means which renders apparent and immediate an inappropriate use of the device.

[0041] After coupling inside the case, the male is axially rotatable respect to the female, to avoid damages to the ear of the animal, for example if the device becomes snagged in an obstruction, such as a fence or gate. Preferably, the male is also partially slidable within the case.

[0042] According to the present invention, the head of the male 40 includes a tip portion 60, the female includes a thorough hole 22 and tamperproof fastening means 23 adapted to block the tip portion 60 in the thorough hole 22 so that, after or during male-female coupling, the tip portion 60 detaches from the male, irremovably becomes a part of the female 20 and definitely closes the hole 22 in tamperproof manner, leaving the stem 41 free to move inside the case 21, separately from the tip portion.

[0043] More particularly, the stem is slidable in a predetermined measure inside the case and is rotatable respect to the case and the tip portion blocked in the case.

[0044] Advantageously, after male and female coupling, the tag device is highly reliable for tamperproof, because the bottom aperture 24 of the case is completely closed by the tip portion, which is irremovably blocked in the female, preventing an access to the case 21, but at the same time, before coupling the male 40 into the female 20, the bottom aperture 24 is opened and thus it may be used, for instance, to carry a container for tissue sampling.

[0045] In other words, according to the invention, the tip portion 60 of the tag device 1 is a part of the male 40 before male-female coupling and it detaches from the male 40 after coupling, becoming part of the female 40, forming a bottom hard seal for the case.

[0046] In this respect, at least a part 63 of the tip portion 60 is adapted to be in full adherence with a part of the case 21 towards the bottom aperture 24 of the case 21, to prevent an access to the case 21 through the bottom aperture 24. The size and shape of the case 21 and tip portion 60 prevent that a tool may be inserted between them, thus preventing access to the case to force the flange 25 and extract the male from the top aperture 26.

[0047] According to an embodiment of the invention, the tamperproof fastening means 23 are in a body of the case 21. For instance, with reference to FIG. 2, the case 21 has a recessed portion wherein a protrusion 63 of the tip portion 60 may enter in undercut, when the male is axially inserted from the top to the bottom of FIG. 2. Once the tip portion 60 is engaged in the recess, and the male is pulled from the bottom to the top of the FIG. 2 or is rotated, the stem 41 disengages from the tip portion 60, which is now part of the female 10.

[0048] FIG. 3 schematically represents a male according to an embodiment of the invention which is described hereafter. The male 40 has a cap 49 having a size greater than a size of the top aperture 26 of the female which is intended to remain outside the case. The stem 41 is between the cap 49 and the tip portion 60; this last is part of the male 40, before insertion into the female, as said above.

[0049] In one aspect of the invention, the tip portion 60 is fixed to the stem 41 before coupling male 40 and female 20, and the stem 41 is detached from the tip portion 60, after or during male 40 and female 20 coupling. A weakening line is provided between the tip portion and the stem, to simplify their detachment during or after insertion in the female.

[0050] The tip portion 60 and the stem 41 may be in different materials. For instance, the tip portion 60 is in a harder material than the material of the stem 41. Advantageously, the tip portion 60 in hard material may easily enter the recess in the case 21 and better close and protect the bottom aperture 24 of the case. The tip portion 60 is fixed on the male 40, for example, with ultrasonic welding.

[0051] The head of male 40 includes also a distal portion 43 (or distal end) which forms another tip adapted to remain on the stem 41 when the tip portion 60 is detached from the stem and blocked in the female. The distal portion 43 is adapted to engage the flange 25, when the male is pulled towards the top of FIG. 2, so preventing the male exiting through the top aperture 26. The distal portion 43 is between the stem 41 and the tip portion 60. The distal portion may be in a different material respect the stem and/or the tip portion; when ultrasonic welding is used for connecting the tip portion 60 on the male 40, the materials of the tip portion 60 and the distal portion 43 are selected accordingly, i.e. to improve ultrasonic welding.

[0052] In the through hole 22, a tissue container 300 may be hold for instance in correspondence to the bottom aperture 24, as schematically represented in FIG. 6, where the male has not yet been completely coupled to the female. This drawing is only schematic and the tissue container 300 may be retained differently in the female, for instance only in the flange 25 or in the middle of the through hole.

[0053] When the male in inserted in the female, the tip portion 60 contacts the container 300 and pushes it out from the bottom aperture 24 of the case 21, and then closes the aperture 24 in tamperproof manner. Cutting means are arranged on the male 40 or on the female 20 or on the container 300 to cut a tissue of the animal, when the male 40 is inserted in the female 20. A plug 400 is provided to close the container, after sampling.

[0054] According to FIGS. 4 and 5, another embodiment not according to the present invention is described, wherein the male is structured to rotate with respect to the tip portion 60 also before male-female coupling. As apparent for the skilled person, many features already disclosed above apply also to the second embodiment and thus are not repeated, for conciseness.

[0055] The male 40 of FIG. 5 comprises a stem 41 with a distal portion 43 which is engaged in slidable manner with a tip portion 60. The tip portion may rotate with respect to the stem and may also be retracted in a predetermined measure within the distal portion 43 or extended, as represented in FIG. 5.

[0056] When the male 40 in inserted in the female through the top aperture 26 of the flange, the tip portion 60 and the distal portion 43 pass through the flange 25, and then the tip portion is blocked in the fastening means 23, in the body of the female, becoming part of the female. The stem 41 may slide in the predetermined measure inside the case and may rotate on the tip portion 60, while the tip portion is fixed in the female body.

[0057] While examples of the male 40 with a tip portion 60 adapted to be blocked in the case 21 have been given with reference to FIGS. 3 and 5, other embodiments not falling within the scope of the present invention are not limited to these examples. For instance, the male 1 may be in different shapes but always whitin the scope of protection of the present invention, i.e. with a tip portion which is adapted to close the case in tamperproof manner after male-female coupling, and firmly remain in the case, leaving the male free to move in the case.

[0058] Advantageously, the device according to the present invention is easy to be manufactured, cost effective, and easy to be applied to the animal, adaptable to different kind of application, i.e. for visual tagging, electronic tagging or tissue sampling, and highly reliable for tamperproof.
