Description

  The present invention relates to an animal ear tag, and more particularly, to an animal ear tag that is not dropped off even when worn on a soft ear shell of an animal that has just been born.

  Conventionally, livestock such as cattle, sheep, goats, and pigs are equipped with a solid discriminator called an ear tag on the ear shell as a means of solid discriminating when reared on a ranch or pig farm. The ear tag usually has an animal registration number printed on the bill portion, but is often printed with an enlarged number that is easily visible from the outside in a ranch or pig farm.

  There are two-piece ear tags and one-piece ear tags. The two-piece ear tag is composed of a male ear tag and a female ear tag. The male ear tag includes a bill portion and a shaft portion that is sharply formed at the bill portion and has a free end penetrating the animal's ear shell. The female ear tag has a hole through which the tip of the shaft that penetrates the animal's ear is inserted, and a receiving portion of the tip that holds the tip with play. On the other hand, a one-piece type ear tag is composed of a single bill portion and a shaft portion protruding from the bill portion, and the tip portion of the shaft portion is a shaft portion after penetrating the animal ear shell. Is bent so that it does not fall out of the ear.

  Such ear tags have been used for a long time as means for identifying individuals attached to the ear shells of animals, and in recent years, as described in Patent Document 1, they are used in animal management systems using computers. And is used for tracking animal breeding and fattening environments.

  FIG. 1A shows the configuration of a conventional two-piece animal ear tag 92. The two-piece ear tag 92 includes a male ear tag 1M and a female ear tag 1F. The male ear tag 1M has a tag part 2 on which an animal registration number or an enlarged number can be printed on the surface, and a shaft part 3 protruding from the back side of the tag part 2. A locking protrusion 3 </ b> A that is tapered after being bulged with respect to the shaft portion 3 is provided at the distal end portion of the shaft portion 3. Similarly, the female ear tag 1F receives the tag 2 on which the animal registration number and the enlarged number can be printed, the through-hole 5 through which the locking protrusion 3A is inserted, and the locking protrusion 3A. There is a locking projection receiving portion 6 (see FIG. 1B) that stops.

  As shown in FIG. 1 (b), the conventional two-piece ear tag 92 configured as described above has a locking projection 3A of the shaft portion 3 after the shaft portion 3 has penetrated the animal ear shell. Is inserted into the through-hole 5 and attached to the animal ear shell. The locking projection 3A of the shaft portion 3 of the male ear tag 1M inserted through the through hole 5 of the female ear tag 1F is connected to the locking projection receiving portion 6 provided on the back surface of the through hole 5 of the female ear tag 1F. Retained.

  FIG. 2A shows the configuration of a conventional one-piece ear tag 91. The one-piece type ear tag 91 is composed of a tag part 7 on which an animal registration number or an enlarged number can be printed on the surface, and a shaft part 8 protruding from the back side of the tag part 7. . The shaft portion 8 has flexibility, and a locking portion 8A bulged in a direction orthogonal to the shaft portion 8 is provided at the tip portion. One end of the locking portion 8A is tapered.

  As shown in FIG. 2B, the conventional one-piece type ear tag 91 configured as described above deforms the flexible shaft portion 8 so that the tip of the locking portion 3A can be used as the animal ear shell Y. If the shaft portion 8 is returned to the original position after penetrating the animal's ear shell Y in the direction of, as shown in FIG. 2 (c), the locking portion 8A is orthogonal to the shaft portion 8, The shaft portion 8 cannot pass through the animal ear shell Y and is attached to the animal ear shell Y.

  However, such an ear tag is not a problem because it is firmly fixed to the ear shell when the ear shell is attached to a hard ear to some extent even when it is just after birth like a cow, but it is short-term like a pig. In the case of an animal that grows in between, if the ear tag is inserted through the ear shell immediately after being born, the ear shell is soft, so the hole that was opened when the ear tag was attached becomes larger and then larger There was a problem that the tag of the ear tag passed through the hole and the ear tag fell off.

  Actually, as shown in FIG. 3 (a), among the piglets PL immediately after being born, there is a kind in which the earshell Y is soft and hangs down. For example, when a two-piece ear tag 92 consisting of a male ear tag 1M and a female ear tag 1F is attached to the ear shell Y in such a state by the above-described method, the piglet PL grows to be a pork pig. About half of the ear tags 92 had been dropped half a year after shipment. This is because the internal structure of the ear shell Y of the piglet PL has not been established. If a small force is constantly applied to the hole to which the ear tag 92 is attached, the internal structure is established around the hole. This is because it is difficult to do so because the hole becomes larger as the ear shell grows.

  On the other hand, the piglet PL grows remarkably fast, and is weaned from the 2nd to the 4th week after birth, but the structure of the earshell Y of the piglet PG at the time of weaning is almost the same as the earshell of the grown pig. The wall is thick and solid. For example, as shown in FIG. 3 (b), when the ear tag was attached to a pig PG having a thick ear shell Y and a thick wall, the drop rate of the ear tag was low and 5% or less. Therefore, the ear tags are often attached to the piglets after weaning when the ear shell is thick and the internal tissue is established.

  However, when ear tags are attached to the piglets at the time of weaning, a large number of piglets were born from one mother pig. When breastfeeding was done to other mother pigs, the parent-child relationship of the pigs was lost, and there was a new problem that the mother pigs were evaluated based on the quality of the slaughtered meat. .

  Therefore, an object of the present invention is to prevent slipping on the ear shell even when the ear shell is attached by passing through the ear shell of an animal such as a piglet, goat, or sheep with a soft ear shell immediately after being born. An object of the present invention is to provide an excellent ear tag for animals without damaging the ear shell of an animal with an ear tag attached to the ear shell and without fear of dropping off of the ear tag due to damage to the ear shell.

The first aspect of the present invention that achieves the above-mentioned object is an animal ear tag comprising at least one bill portion and a shaft portion, the shaft portion being attached to the animal through the animal ear shell , In a two-piece ear tag composed of a male ear tag having a shaft protruding from a bill portion and a female ear tag in which the tip of the shaft portion penetrating the animal's ear shell is fitted. It is possible to secure a space between the animal ear shell and the bill portion on the surface of the bill portion facing the animal ear shell and to prevent the bill portion from moving on the animal ear shell. only set the slip section, the slip preventing portion, together with at least one to provide a surface facing the concha of the male ear tags and female ear tags animals, the slip section, the circumferential groove in the inner peripheral portion It constitutes a ring-shaped spacer member having the spacer member, especially the mounted by fitting a circumferential groove on the edge portion of the tongue Is an ear tags for animals to be.

The second form of the present invention that achieves the above-mentioned object is an animal ear tag comprising at least one bill part and a shaft part, the shaft part being attached to the animal through the animal's ear shell, It consists of a single bill part and a shaft part projecting from this bill part, and the tip part of the shaft part is used to prevent the shaft part from falling off the ear shell after penetrating the animal ear shell. Further, in the one-piece type ear tag configured to be deformed to be larger than the through-hole opened in the ear shell, the animal ear shell and the bill are placed on the surface of the at least one bill portion facing the animal ear shell. A non-slip part that secures a space between the card part and prevents movement of the bill part on the ear shell of the animal is provided, and the non-slip part faces the animal ear shell of the tag part. The anti-slip portion is formed of a ring-shaped spacer member having a circumferential groove on the inner peripheral portion, and the spacer portion Is the ear tags for animals, characterized in that attached by fitting the circumferential groove in the edge of the tongue.

  According to the present invention, in an ear tag including a shaft portion and a bill portion, a space between the animal ear shell and the bill portion is secured on a surface of at least one bill portion facing the animal ear shell. In addition, by providing an anti-slip part that can prevent movement of the bill part on the animal's ear shell, when the ear tag is worn through the ear shell of the animal's child immediately after birth, Since the shaft portion does not move relative to the ear shell by the anti-slip portion, the hole opened in the ear shell does not become larger due to the movement of the shaft portion, and the ear mark can be prevented from dropping without damaging the ear shell.

  Hereinafter, embodiments of the present invention will be described in detail based on specific examples with reference to the accompanying drawings. In order to make the description easy to understand, the same components as those of the conventional ear tags 91 and 92 described with reference to FIGS. 1 and 2 are denoted by the same reference numerals. Moreover, in the Example demonstrated below, a piglet is mentioned as an example and demonstrated.

  Prior to the present invention, the present inventor investigated the cause of the large dropout rate of the ear tag when the ear tag was attached to a newborn piglet. As a result, when the ear tags are attached to the piglet earshells at the time of weaning, the structure of the earshells of the piglets is not so different from that of the grown pig earshells, but soon after birth. We found that the internal structure of the piglet earshell was not established. And if there is a hole with an ear tag attached to the earshell of a piglet just after birth, even if a small force is applied to this hole continuously, the internal tissue is not established around the hole I understood that. On the other hand, even if a small hole was made in the ear shell of a piglet immediately after birth, it was found that if there was no external force applied, the hole had an excellent regenerative power that would close with time.

  From this, the inner structure of the ear shell like a newborn piglet has not been established, and the ear tag attached to the ear shell when the ear shell is soft suppresses movement to the ear shell as much as possible. The present inventor has found that the stress on the ear shell from the shaft portion penetrating the ear shell should be reduced as much as possible.

  On the other hand, even when an ear tag is attached to a pig's ear shell at the time of weaning when the inner tissue of the ear shell is almost established, the ear shell part to which the ear tag is attached is necrotic due to poor blood circulation due to compression, resulting in a large hole. It was also found that the ear tags may fall off. This is because, in the case of pigs, the weight exceeds 100 kg in about 6 months after birth and it can be shipped, but since the ears grow during this time, the thickness of the ear shell increases as the ears grow. In other words, like a conventional ear tag, a tag with a fixed gap between the ear shells, for example, the ear tag tag part and the bill part of the ear tag when worn according to the ear shell of the piglet at the time of weaning. Once the interval is determined, the bills firmly hold the earshells as the pigs grow, blocking blood circulation and causing necrosis in the earshells.

  In contrast to the conventional problems, the animal ear tag of the present invention has an ear tag that penetrates the ear shell of an animal such as a piglet, goat, or sheep with a soft ear shell immediately after being born. However, by preventing slipping on the ear shell, the ear shell of the animal wearing the ear tag on the ear shell will not be damaged, and there is no risk of the ear mark falling off due to damage to the ear shell. The configuration of the ear tag according to the present invention will be described in detail below with reference to FIGS. 4 to 8 by taking a piglet ear shell as an example.

FIG. 4A shows the configuration of the two-piece ear tag 10 according to the first embodiment of the present invention. The two-piece type ear tag 10 for pigs of this embodiment is composed of a male ear tag 1M and a female ear tag 1F. The male ear tag 1M has a tag part 2 on which an animal registration number or an enlarged number can be printed on the surface, and a shaft part 3 protruding from the back side of the tag part 2. A locking protrusion 3 </ b> A that is tapered after being bulged with respect to the shaft portion 3 is provided at the distal end portion of the shaft portion 3. Similarly, the female ear tag 1F accepts the tag portion 4 on which the animal registration number and the enlarged number can be printed on the surface, the through hole 5 through which the locking projection 3A is inserted, and the locking projection 3A. There is a locking projection receiving portion 6 (see FIG. 4B) that stops.

  Further, in this embodiment, an anti-slip portion is provided around the through hole 5 of the female ear tag 1F. Although the anti-slip portion can be formed by expanding the periphery of the through hole 5 of the female ear tag 1F, generally, the anti-slip portion is formed using a spacer member. As such a spacer member, a ring-shaped and flexible member, for example, a sponge 11 having a high foaming rate, can be disposed around the through-hole 5 of the female ear tag 1F.

  The diameter of the hole opened at the center of the sponge 11 is larger than the diameter of the through hole 5 of the female ear tag 1F. Further, as shown in FIG. 4B, the thickness of the sponge 11 is such that the locking projection 3A of the male ear tag 1M is inserted into the through hole 5 of the female ear tag 1F, and the male ear mark 1F is inserted into the male ear tag 1F. What is necessary is just to prevent the ear tag 10 from moving with respect to the ear shell while the model ear tag 1M is attached. That is, the distance between the sponge 11 and the back surface of the male ear tag 1M is set to a value that is about the thickness of the ear shell of a piglet that has just been born (for example, about 2-3 mm, Make slight contact with the ear shell, but do not apply pressure.

  The sponge 11 can be fixed to the surface around the through hole 5 of the female ear tag 1F with an adhesive or a double-sided tape. The sponge 11 can be temporarily fixed with an adhesive or a double-sided tape. This is because the sponge 11 can be detached from the female ear tag 1F in a state where the male ear tag 1M is attached with the piglet ear shell inserted through the female ear tag 1F. Further, if the sponge 11 is separated from the ear tag 10, the sponge 11 can be attached to any pre-made ear tag and can be used as the ear tag of the present invention.

  As shown in FIG. 4 (c), the two-piece type ear tag 10 configured as described above is used after the shaft part 3 of the male ear mark 1M is passed through the ear shell Y of the piglet. By inserting the stop projection 3A into the through hole 5 of the female ear tag 1F and holding it in the locking projection receiving part 6 provided on the back surface of the through hole 5 of the female ear tag 1F, the ear shell Y of the piglet Can be attached to. In this state, the piglet earshell Y is sandwiched between the back surface of the male ear tag 1M and the sponge 11, but since the sponge 11 is flexible, the sponge 11 moves the sponge 11 by the sponge 11. However, the piglet's earshell Y is not pressed firmly by the ear tag 10.

Since the diameter of the sponge 11 is larger than the diameter of the hole opened in the ear shell Y by the shaft portion 3 and the ear mark 10 is difficult to move relative to the ear shell Y by the sponge 11, the shaft portion 3 is The hole formed in the shell Y is not compressed, and the wound of the hole formed in the ear shell Y is healed over time. Further, even if the thickness of the ear shell Y increases as the piglet grows, the flexible sponge 11 contracts, so that the ear shell Y is not strongly pressed by the ear tag 10. Incidentally, the sponge 11 may be about 0.5 mm, are effective as compared with the case where there is no slip stopper plate portion.

  As in the first embodiment, the spacer member is preferably attached to the back surface of the female ear tag 1F. This is because the two-piece type ear tag 10 has a receiving portion 6 for receiving the locking projection 3A of the shaft portion 3 outside the female ear tag 1F, and this receiving portion 6 is placed behind the ear shell Y. This is because it is better. This is because when the receiving portion 6 is on the front side of the ear shell Y, this becomes resistance, and when the ear is pinched or rubbed, it is caught and the risk of falling off increases.

  On the other hand, the male ear tag 1M has a shaft portion 3 protruding from the side facing the ear shell 1M, but the opposite side is a flat surface. For this reason, it is desirable to attach the ear tag 10 to the ear shell so that the male bill-type ear tag 1M is outside the ear shell Y and the female ear tag 1F is inside the ear shell Y. However, the space member can of course be attached to the back side of the male ear tag 1M.

  FIG. 5 (a) shows the structure of a modified embodiment of the spacer member 11 of the first embodiment of the present invention in the two-piece ear tag 10 shown in FIG. 4 (a). Only the mark 1F is shown. In addition, some examples from here explain what the shape of the female ear tag 1F is circular. The sponge 11 as the spacer member shown in FIG. 4A has a ring shape, but in this modified embodiment, the shape of the sponge 11 is a cross shape. There is no difference in other configurations of the sponge 11.

  FIG. 5B shows a configuration of another modified embodiment of the first embodiment of the present invention in the two-piece ear tag 10 shown in FIG. Only the configuration is shown. The sponge 11 as the spacer member shown in FIG. 4A has a ring shape, but in this modified embodiment, the shape of the sponge 11 and the shape of the hole at the center are rectangular. There is no difference in other configurations of the sponge 11. The shape of the spacer 11 is not limited to these shapes.

  FIG. 5C shows the configuration of the second embodiment of the present invention in the two-piece type ear tag 10 and shows the configuration of only the female type ear tag 1F. In the second embodiment, instead of the sponge 11 of the first embodiment, a brush-like portion 12 is provided in a portion around the through hole 5 of the female ear tag 1F as a spacer member. The brush-like part 12 is obtained by planting a large number of various animal hairs, plant fibers, synthetic resins and the like around the through hole 5 of the female ear tag 1F. The length of the bristles of the brush-like portion 12 may be about the same as the thickness of the sponge 11 of the first embodiment (however, even about 0.5 mm is effective). This brush-shaped part 12 also makes it difficult to move the ear tag 10 after mounting with respect to the ear shell Y. Moreover, when the brush-shaped part 12 is a product made from a synthetic resin, it can form simultaneously with the shaping | molding of an ear mark.

  5 (d), (e) and (f) show the configurations of the third to fifth embodiments of the present invention in the two-piece type ear tag 10, and only the female type ear tag 1F is shown. Is shown. In the third embodiment shown in FIG. 5D, instead of the sponge 11 of the first embodiment as a spacer member, a plurality of small coil springs are provided around the through hole 5 of the female ear tag 1F. 13 is attached. In this embodiment, the coil springs 13 are evenly arranged on the circumference, and the height thereof is about the same as the thickness of the sponge 11 of the first embodiment. This coil spring 13 also makes it difficult to move the ear tag 10 after mounting with respect to the ear shell Y.

  The number of the coil springs 13 is not limited to four, and at least one is sufficient. In the case of one, the female ear tag 1F tilts with respect to the piglet ear shell, but even in this state, a space is secured between the hole opened in the ear shell and the female ear tag 1F. effective.

  In the fourth embodiment shown in FIG. 5 (e), instead of the sponge 11 of the first embodiment as a spacer member, one large coil spring 14 is provided around the through hole 5 of the female ear tag 1F. It is attached. Further, in the fifth embodiment shown in FIG. 5 (f), a plurality of leaf springs are provided around the through hole 5 of the female ear tag 1F instead of the sponge 11 of the first embodiment as a spacer member. 15 is attached. In this embodiment, the leaf springs 15 are evenly arranged on the circumference, and the height of the tip portion of the leaf spring 15 from the tag portion 4 is approximately the same as the thickness of the sponge 11 of the first embodiment. Yes. Both the coil spring 14 and the leaf spring 15 make it difficult to move the ear tag 10 after mounting with respect to the ear shell Y. The number of leaf springs 15 may be one as described above.

  6 (a) and 6 (b) show the configurations of the sixth and seventh embodiments of the present invention in the two-piece type ear tag 10 and show the configuration of only the female type ear tag 1F. . In the sixth embodiment, instead of the sponge 11 of the first embodiment as a spacer member, a plurality of spherical balls 16 are provided around the through hole 5 of the female ear tag 1F. In the seventh embodiment, instead of the sponge 11 of the first embodiment, a plurality of hemispherical domes 17 are provided around the through hole 5 of the female ear tag 1F as a spacer member. Yes.

  The ball 16 and the dome 17 are made of a soft synthetic resin, and the ball 16 and the dome 17 are formed into a hollow and elastic balloon-like state by the resin having a reduced thickness. In this embodiment, the balls 16 and the dome 17 are evenly arranged around the through-hole 5 of the female ear tag 1F so as to support the surface. However, the number of the balls 16 and the dome 17 is 1 as described above. Individuals may be used. The height of the ball 16 and the dome 17 may be approximately the same as the thickness of the sponge 11 of the first embodiment. The ball 16 and the dome 17 also make it difficult to move the ear tag 10 after mounting with respect to the ear shell Y. The ball 16 and the dome 17 are made of the same material as that of the bill portion 4 and can be made by integral molding.

  Further, the ball 16 and the dome 17 may be configured to squeeze or disassemble in a short time of about two weeks. This is because the piglet's ear shell is soft, and the damage period of the ear tag is about 2 weeks after birth. After that, the ear tag may directly touch the ear shell or the axis of the ear tag may move. It is.

  FIG. 6C shows the configuration of the eighth embodiment of the present invention in the two-piece ear tag 10 and shows the configuration of only the female ear tag 1F. In the eighth embodiment, the outer edge portion 18 of the female ear tag 1F is formed of a flexible synthetic resin, and is bent in the direction of the male ear tag 1M to form a spacer member. As a result, when the outer edge portion 18 of the female ear tag 1F receives stress from the male ear tag 1M side, it bends and deforms. The height of the outer edge portion 18 of the female ear tag 1F from the bill portion 4 may be approximately the same as the thickness of the sponge 11 of the first embodiment. The outer edge portion 18 of the female ear tag 1F also makes it difficult to move the ear tag 10 after being attached to the ear shell Y.

  FIG. 6D shows the configuration of the ninth embodiment of the present invention in the two-piece type ear tag 10 and shows the configuration of only the female ear tag 1F. In the ninth embodiment, instead of the sponge 11 of the first embodiment as a spacer member, the cross section is triangular from the periphery of the through-hole 5 of the female ear tag 1F toward the outer edge portion 18 of the female ear tag 1F. Shaped projections 19 are provided radially. The cross section of the protrusion 19 is the smallest at the portion near the through hole 5 of the female ear tag 1F and gradually increases toward the outer edge portion 18.

  The height of the projection 19 at the outer edge 18 of the female ear tag 1F may be approximately the same as the thickness of the sponge 11 of the first embodiment. The protrusion 19 may be formed of the same material as the bill portion 4, but only the protrusion 19 may be formed of a flexible synthetic resin. This protrusion 19 makes it difficult for the ear tag 10 after attachment to the ear shell Y to move. Further, the projections 19 do not have to be evenly arranged, and the number of the projections 19 may be at least one as described above.

  FIGS. 6 (e) and 6 (f) show the configurations of the tenth and eleventh embodiments of the present invention in the two-piece type ear tag 10, and show the configuration of only the female ear tag 1F. In the tenth embodiment, as in the fourth embodiment shown in FIG. 5 (e), a large flat plate coil in which a flat plate is spirally formed around the through hole 5 of the female ear tag 1F. A spring 20 is attached.

  In the eleventh embodiment shown in FIG. 6 (f), instead of the sponge 11 of the first embodiment as a spacer member, a metal wire or a synthetic wire is formed around the through hole 5 of the female ear tag 1F. A wire wool ring 21 in which wire wool obtained by rounding a resin wire into a mesh shape is attached is attached. The height of the flat coil spring 20 and the thickness of the wire wool ring 21 may be approximately the same as the thickness of the sponge 11 of the first embodiment. The height of the flat coil spring 20 and the wire wool ring 21 also make it difficult for the ear tag 10 after mounting to the ear shell Y to move. In the case of the metal wool ring 21, as described above, the metal wool may rust and disappear in about two weeks.

  FIG. 7A shows the configuration of the first embodiment of the present invention in the earpiece 30 for a one-piece type pig. The ear tag 30 for a one-piece type pig is composed of a tag part 7 on which an animal registration number or an enlarged number can be printed on the surface, and a shaft part 8 protruding from the back side of the tag part 7. Has been. The shaft portion 8 has flexibility, and a locking portion 8A bulged in a direction orthogonal to the shaft portion 8 is provided at the tip portion. One end of the locking portion 8A is tapered.

  Further, in this embodiment, the same member as the ring-like flexible member described in FIG. 4A, for example, sponge 11 is arranged as a spacer member around the protruding position of the shaft portion 8 of the bill portion 7. ing. The diameter of the hole opened in the center of the sponge 11 is larger than the diameter of the shaft 8. The thickness of the sponge 11 may be set to a value such that the surface of the sponge 11 touches the ear shell while the ear tag 30 is attached to the ear shell of the piglet.

  The sponge 11 can be fixed to the surface around the protruding portion of the shaft portion 8 of the bill portion 7 with an adhesive or a double-sided tape. The sponge 11 can be temporarily fixed with an adhesive or a double-sided tape. This is because the sponge 11 can be detached from the bill portion 8 in a state where the shaft portion 8 is inserted into the earshell of the piglet and attached to the earshell.

  As shown in FIG. 7B, the 1-piece type ear tag 30 configured as described above deforms the flexible shaft portion 8, and the locking portion 8A has a tapered portion of the earshell Y of the piglet. After passing through the earshell Y of the piglet in the direction, if the shaft portion 8 is returned to the original, as shown in FIG. 7C, the locking portion 8A is orthogonal to the shaft portion 8, The locking portion 8A cannot pass through the earshell Y of the piglet and is attached to the earshell Y of the piglet. In this state, the earshell Y of the piglet is sandwiched between the locking portion 8A and the sponge 11, but since the sponge 11 is flexible, the earshell Y of the piglet is not compressed by the ear tag 30.

  Since the diameter of the sponge 11 is larger than the diameter of the hole opened in the ear shell Y by the shaft portion 8 and the ear mark 30 is difficult to move relative to the ear shell Y by the sponge 11, the shaft portion 8 is The hole formed in the shell Y is not compressed, and the wound of the hole formed in the ear shell Y is healed over time. Even if the thickness of the earshell Y increases as the piglet grows, the flexible sponge 11 contracts, so that the earshell Y is not compressed by the ear tag 30.

  The structure of the second to eleventh embodiments of the two-piece type ear tag 10 can be applied to the bill portion 7 of the ear tag 30 also for the one-piece type ear tag 30.

  FIGS. 8A to 8C show the configuration of a twelfth embodiment of the present invention in a two-piece ear tag 10. As shown in FIG. 8A, in the twelfth embodiment, a bellows-like bellows 22 is attached to the shaft portion 3 protruding from the bill portion 2 of the male ear tag 1M. The bellows 22 is a hollow member made of a flexible synthetic resin and is not fixed to the shaft portion 3. The configuration of the female ear tag 1F may be the same as that of the conventional one, and will not be described here. As shown in FIG. 8 (b), the axial length of the bellows 22 is such that the through-hole 5 of the female ear tag 1F is inserted after the locking projection 3A of the male ear tag 1M is inserted through the ear shell Y of the piglet. In such a state, the bellows 22 may be set to such a value that the bellows 22 touches the earshell Y of the piglet lightly.

  The two-piece type ear tag 10 of the twelfth embodiment configured as described above has an earshell Y as the piglet grows from the state shown in FIG. 8B as shown in FIG. Since the bellows 22 is compressed and contracted, the grown piglet ear shell Y is not compressed by the ear tag 10.

  FIGS. 8D and 8E show the configuration of the thirteenth embodiment of the present invention in the two-piece type ear tag 10 and show the configuration of only the male ear tag 1M. In the thirteenth embodiment, any one of the configurations of the first to eleventh embodiments of the present invention in the two-piece ear tag 10 described above can be used as the female ear mark 1F. The thirteenth embodiment is different from the configuration of the shaft portion 3 in the first to eleventh embodiments in that the shaft portion 3 of the male ear tag 1M is a bellows shaft 23 having a bellows structure.

  The state shown in FIG. 8D is a state in which the bellows shaft 23 of the thirteenth embodiment is most contracted, and the bellows shaft 23 is not further contracted. The state shown in FIG. 8D is the same as the length of the shaft portion 3 of a normal male ear tag 1M having no bellows structure. In the thirteenth embodiment, as described with reference to FIGS. 8B and 8C, when the piglet grows and the thickness of the earshell Y increases, the bill portion 2 is pushed by the earshell Y. The bellows shaft 23 extends. As a result, the grown piglet ear shell Y is not compressed by the ear tag 10 due to the contraction of the spacer members 11 to 21 and the expansion effect of the bellows shaft 23 in the female ear tag 1F.

  FIGS. 8F and 8G show the configuration of the fourteenth embodiment of the present invention in the two-piece type ear tag 10 and show the configuration of only the male ear tag 1M. In the fourteenth embodiment, any of the configurations of the first to eleventh embodiments of the present invention in the above-described two-piece ear tag 10 can be used as the female ear mark 1F. The fourteenth embodiment is different from the configuration of the shaft portion 3 in the first to eleventh embodiments in that the shaft portion 3 of the male ear tag 1M is a telescopic shaft 24 that can be expanded and contracted.

  The state shown in FIG. 8F is a state in which the telescopic shaft 24 of the fourteenth embodiment is most contracted, and the telescopic shaft 24 is not further contracted. The state shown in FIG. 8G is the same as the length of the shaft portion 3 of a normal male ear tag 1M that does not have a stretchable structure. In the fourteenth embodiment, as described with reference to FIGS. 8B and 8C, when the piglet grows and the thickness of the earshell Y increases, the bill portion 2 is pushed by the earshell Y. The telescopic shaft 24 extends. As a result, the grown piglet ear shell Y is not compressed by the ear tag 10 due to the contraction of the spacer members 11 to 21 and the extension effect of the telescopic shaft 24 in the female ear tag 1F.

  As described above, the expansion / contraction mechanism of the shaft part 3 of the male ear tag 1M has been described with reference to FIG. 8, but the length of the shaft part 3 of the male ear tag 1M is about half as shown in FIG. 10 (c). It is also possible to adopt a configuration in which the locking projection 3A and the shaft portion 3 are solidified with a resin wax (wax) after being connected to each other by the string 25 in a slackened state with the locking projection 3A and the shaft portion 3 being loosened. Since the length of the cord 25 is longer than the length of the shaft portion formed of the resin wax 26, the cord 25 is stretched as shown in FIG. 10 (d) and the shaft portion 3 is stretched when the resin wax 26 is melted. It is also possible to do.

Further, FIG. 10 (e) shows that the shaft portion 3 of the male ear tag 1M is entirely made of resin wax 26, and in this resin wax 26, the shaft length connecting the locking projection 3A and the shaft portion 3 is as follows. Also shows an embodiment in which a long string 25 is embedded. Since the length of the string 25 is longer than the length of the shaft portion 3 formed of the resin wax 26, the string 25 extends as shown in FIG. 10 (f) and the shaft portion 3 extends when the resin wax 26 melts. It is also possible to configure.

  FIG. 9 shows a configuration of a spacer member 40 that can be used in common for the two-piece ear tag 10 and the one-piece ear tag 30. In the embodiment described before, the spacer members 11 to 21 are provided around the shaft portion 3, but the spacer member 40 described in FIG. 9A is as shown in FIG. 9B. The peripheral part of the bill part 2 of the male ear tag 1M or the peripheral part of the tag part 4 of the female ear tag 1F is configured to be attached. The spacer member 40 is a ring-shaped member made of a flexible material such as sponge, and has a groove 41 that matches the outer shape of the tag portions 2 and 4 on the inner peripheral portion thereof.

  In the spacer member 40 of this embodiment, as shown in FIG. 9B, the peripheral portion of the bill portion 2 of the male ear tag 1M and the peripheral portion of the bill portion 4 of the female ear tag 1F are inserted into the groove 41. By doing so, it can be attached to the male ear tag 1M and the female ear tag 1F. Therefore, the spacer member 40 of this embodiment can be attached to a one-piece type ear tag.

  Furthermore, the spacer member in the above-described embodiment can be formed of a member that decays and disappears over time. It is also possible to embed a communication device such as an RFID (wireless authentication) tag in the spacer member.

  Furthermore, instead of embedding a communication device such as RFID in the spacer member, the spacer member 40 of the embodiment described in FIG. 9 can be used. For example, the spacer member described in FIG. 9A is provided at the edge of the RFID tag 42 as shown in FIG. 10A, which has a hole 43 and can be attached to the shaft of the ear tag. By covering as shown in FIG. 10 (b), it becomes possible to attach a one-piece ear tag or a two-piece ear tag in which the RFID 42 is attached to the shaft part to the ear shell of a piglet.

  As described above, the ear tag of the embodiment of the present invention has been described in detail with respect to the case where the ear shell at the time of birth is soft and attached to the ear shell of the piglet. Needless to say, it is also effective to attach to the ear shell of a soft animal such as a goat or a sheep whose ear shell is short after birth.

  In addition to these, in the spacer members 11, 16, 17 and the like of the present invention, if an anti-inflammatory agent or antipyretic agent is soaked in or incorporated in the sponge, these agents will open in the ear shell after mounting. Inflammation of the formed through-hole can be suppressed.
