Description

  The present invention relates to a resin fixture mainly used for individual identification of animals and the like, store sales products such as apparel products and daily necessities or logistics products, and more specifically, resin fixtures that prevent damage to an attached body. The present invention relates to a fixture and a resin fixture having improved mounting workability.

Recently, the safety of daily necessities has been emphasized, and consumers are required to disclose information such as safety and quality. In response to this request, in the field of handling animals, as part of various efforts to disclose information, we use tags for identifying individuals such as livestock, pet animals, and wild animals for ecological research. There have been many cases of managing this.
For example, if the livestock is a cow, the “special treatment method for cattle spongiform encephalopathy countermeasures” and the “special treatment method for information management and transmission for individual identification of cows” are used to identify each individual cow. The requirement to wear ear tags is another factor that attracts attention for information management using tags. Various animal tag technologies have been developed in response to such social trends.

A pig ear tag in which the first member is formed of a flexible synthetic resin is disclosed.
In this technique, as disclosed in JP-T-2001-525188, a conical pointed head is formed of a known hard material, for example, a hard synthetic resin. This is to ensure rigidity when the first member is inserted into the pig ear.

  In “Patent Document 2”, the casing is formed of a soft synthetic resin, and a substantially truncated cone-shaped base portion larger than the outer diameter of the tip is formed of a hard synthetic resin at the tip of the core and the core. A technique is disclosed in which a casing and a core are bonded and fixed, and a sharp body made of hard synthetic resin or metal is detachably attached to the base of the base. This technology uses a core rod and a sharp body to make it easier to pierce the animal's ears, and to make it easier for the animal to detach from the fence even if the animal catches it on the fence. The stiff body is separated from the pedestal after it is stabbed into the ears of livestock.

According to the animal ear tag stud and animal ear tag stud / support rod disclosed in the publication of “Patent Document 3”, a hollow shaft is extended from the panel, and a tapered head is provided at the end of the hollow shaft. The hollow part of the shaft has a large diameter on the panel side and a small diameter near the head, and a step is formed at the boundary between the large diameter part and the small diameter part of the hollow part, and the tip part of the head is made non-pointed and elastic. A body-formed stud is described.
The support rod inserted into the hollow portion of the stud forms a pointed portion protruding from the head portion of the stud, while the shoulder of the support rod is brought into contact with the step portion of the hollow portion.
And the technique which penetrates the ear of an animal etc. with a stud and a support rod, and inserts and stops the head of a stud in the hole of a female part is indicated. In this technique, the ear tag stud is softly formed, and the supporting strength is left to maintain the strength when it is inserted into the animal's ear.

  On the other hand, there is an increasing demand for information disclosure on daily necessities other than animals. In response to this demand, for example, one-dimensional barcode, two-dimensional code, or RFID (Radio Frequency Identification) called wireless communication recognition technology enables individual management from the production to consumption of daily necessities, and this management information is consumed. By providing information to consumers, development of so-called traceability systems is also carried out at a rapid pace, in which consumers obtain various types of information on desired daily necessities and make purchase decisions. Along with this, technology for sealing RFID with resin Has also been proposed.

JP-A-2005-149363 JP-A-6-45481

In “Patent Document 4”, a lower base material and an upper base material, which are rolled into a sheet with a thermoplastic elastomer and punched with a punching machine, are prepared, and gold is placed with electronic components interposed between the upper and lower base materials. A technology that sets in a mold, fills the gap between the inner wall surface of the mold and the upper and lower base materials with a thermoplastic elastomer in a plastic state, melts the base material and the filled elastomer, and resin seals the electronic components Is disclosed.
“Patent Document 5” discloses a technique of resin-sealing an electronic component similar to “Patent Document 4”.

According to Patent Literatures 1 to 3, “Patent Literature 1” describes a known hard material, for example, a hard synthetic material, in order to ensure rigidity when the first member is inserted into a pig ear. Since it is made of resin, it is convenient for piercing into the ear, but no measures are taken against damage at the time of piercing. In addition, the attachment body such as an animal is often damaged, and the mounting workability is not considered.
On the other hand, “Patent Document 2” has an advantage that the housing is soft and the core rod and the pointed body are formed hard, and the housing and the core rod are joined and fixed, so that the housing is easily detached even if it is caught on a fence or the like. On the other hand, there is a concern about the strength of the joint, and since there are many problems such as the sharp body separating after installation, this technique also has to be collected, and this technique also provides a measure against scratching and workability during installation. Is not taken into consideration.
Further, in the case of “Patent Document 3”, since the strength of the ear tag stud is softly formed by entrusting the strength retention when the animal is inserted into the ear of the animal, it is gentle to the animal, but there is a problem in strength retention. As can be seen from the fact that the ear tag is easy to remove and this technology also does not take into consideration the scratch countermeasures and installation workability at the time of embedment, any conventional example has a countermeasure against scratches and wearability at the time of embedment. It does not discuss improvement.

  The techniques of the above-mentioned “Patent Document 4” and “Patent Document 5” can be evaluated in that electronic components such as IC tags can be sealed with resin to protect the electronic components. Many such techniques have been proposed. In many cases, an IC tag sealed with a resin is attached to another article such as a product. However, there are no proposals for attaching resin-encapsulated IC tags to other articles.

Therefore, the present invention aims to solve the above-mentioned conventional problems, and typically takes measures against scratches that occur when piercing the mounted body, and can maintain sufficient strength and does not fall off. It is a first object of the present invention to provide a resin fixture that can be attached to a body to be attached.
It is a second object of the present invention to provide a resin-made fixing tool that can be easily attached when attached to a body to be attached.

In order to achieve the above object, the present invention solves the problem by using the following means.
The first problem-solving means is formed with a flange portion, a shaft portion extending from the flange portion, and a stop portion having a jaw portion at the extended end portion of the shaft portion and bulging from the shaft portion. A resin-made fixture made of a female member having a male member and a locking hole for a stop portion of the male member,
The surface of the male member on the shaft side of the flange portion is formed with uneven streaky air circulation grooves, and a plurality of the air circulation grooves are arranged in parallel so that the flange portions can be easily bent from the grooves. A resin fixing device is provided.

  As a second means for solving the problem, a reinforcing piece made of a hard resin is arranged inside the stopper portion of the male member, and this reinforcement piece is formed with a wall that receives a force at the time of insertion applied to the stopper portion. A part for forming a male member other than a piece is formed of a soft resin having good adhesion with the hard resin, and the reinforcing piece is surrounded by the soft resin. A resin fixture subordinate to is provided.

  As a third problem solving means, the reinforcing piece of the male member is formed in a stepped cylindrical shape, the axis thereof is arranged on the substantially axial line of the shaft portion, and the surface of the reinforcing piece in the direction intersecting the axis of the shaft portion is formed. There is provided a resin-made fixing tool subordinate to a second problem solving means characterized in that the wall receives a force at the time of insertion applied to a stopper.

  As a fourth problem-solving means, the second and third features are characterized in that the stop portion cross-sectional portion of the shortest distance from the root of the shaft portion and the stop portion of the male member to the reinforcing piece in the stop portion is used as the fracture portion. A resin fixture dependent on the problem solving means is provided.

  As a fifth problem solving means, it depends on any one of the first to fourth problem solving means characterized in that the shape of the stop portion of the male member is formed in a truncated cone shape with the tip side tapered. A resin fixture is provided.

The sixth problem solving means is dependent on any one of the first to fifth solving means characterized in that a space groove is formed around the locking hole of the female member on the side where the stop portion of the male member is inserted. A resin fixture is provided.

  As a seventh problem solving means, there is provided a resin fixture dependent on any of the first to sixth problem solving means, wherein an information recording body is disposed on a male member or a female member.

  As an eighth problem-solving means, the arrangement structure of the information recording body is covered so as to sandwich the information recording body with a resin substrate and an exterior part formed by injection molding with a resin fused to the substrate. A resin fixture subordinate to the seventh problem-solving means is provided.

  The ninth problem solving means is dependent on the eighth problem solving means characterized in that a part of the exterior surface of the exterior portion is replaced with one surface of the substrate and the information recording body is disposed on the other surface of the substrate. A resin fixture is provided.

  As a tenth problem solving means, there is provided a resin fixture dependent on any one of the seventh to ninth problem solving means, characterized in that an information recording body is attached to a substrate with an adhesive.

The operation of the first problem solving means is as follows.
If there is no air flow groove on the shaft side of the buttocks of the male member as in the prior art, the wound is cut off from the outside air by bleeding due to bleeding when piercing the animal's ear, and the wound is healed Although the present invention is difficult to lead to suppuration or necrosis of the ear, the present invention forms an uneven streaky air flow groove on the shaft side of the buttocks of the male member, and this air flow By arranging a plurality of grooves in parallel so that the buttock can be easily bent from the groove, especially when attaching a resin fixture to the animal ear etc. You will communicate. Therefore, since the wound portion damaged by the perforation of the animal's ear by the male member can be dried, the healing effect of the perforated portion around the axis can be enhanced, and necrosis, suppuration and the like can be prevented. In addition, since the buttock is easy to bend, even if an animal hits the fence etc. and the buttock is caught on the fence etc., it can prevent the buttock from coming off the fence and the resin fixing tool falling off from the animal. . On the other hand, even when the resin-made fixing device of the present invention is used for an attachment body that easily absorbs moisture, such as a cardboard box, even if the cardboard box gets wet, it is the same as other parts of the cardboard box due to the action of the air circulation groove. Since it can be dried at a speed, the cardboard box around the male member remains wet and it can be prevented that the strength is partially insufficient, and the buttock is easy to bend. It can prevent that a collar part remove | deviates from other articles | goods etc. easily, and resin-made fixing tools drop.

In addition to the operational effects of the first problem-solving means, the action of the second problem-solving means is provided with a reinforcing piece in which the shape of the stopper portion of the male member is formed of a hard resin inside the stopper part. A portion for forming a male member other than the reinforcing piece is formed with the hard resin and a soft resin having good adhesiveness after forming a wall that receives a force at the time of insertion applied to the stopper, and the reinforcing piece When the tip of the stopper is inserted into the body to be mounted and the stopper of the male member enters the locking hole of the female member while shrinking, and the stopper passes through the locking hole. In the process of returning to the original size, the reinforcing piece made of hard resin receives the shearing force that acts on the soft resin part of the stopper, so there is no problem in strength. It is possible to cover the surface of the stopper with a soft resin That.
Therefore, since the hard resin part does not touch the body to be mounted, the body to be mounted is not damaged more than necessary. Especially when the body to be mounted is a part of an animal ear or the like, it may cause a wound at the time of insertion. On the other hand, necessary puncture strength can be secured while maintaining a gentle state.
In addition, even if a force is applied to the male member or the female member in the direction in which the stopper is pulled out of the locking hole after the stopper is engaged with the locking hole, the shear that still acts on the soft resin portion of the stopper The reinforcement piece formed of hard resin receives the force and the like. In addition, since the entire reinforcing piece is surrounded by a soft resin, the physical strength of the soft resin acts in addition to the adhesive strength between the hard resin and the soft resin, so that the stopper can be removed. Directional strength can be increased.

  The action of the third problem solving means is that the reinforcing piece of the male member is formed in a stepped cylindrical shape, the axis thereof is arranged on the substantially axial line of the shaft portion, and the reinforcing piece in the direction intersecting the axis of the shaft portion is Since the surface is a wall that receives the force when inserting it into the stopper, in addition to the effect of the second problem solving means, it is formed of a hard resin that receives shearing force acting on the soft resin part of the stopper The reinforcing effect of the reinforcing piece can be further enhanced.

  The action by the fourth problem solving means is that the shortest stop portion cross-sectional portion from the base of the shaft portion and the stop portion of the male member to the reinforcing piece in the stop portion is the fracture portion due to the stress concentration action. When the destructive force in the direction of pulling out from the female member is applied, the joint portion between the shaft portion and the stopper portion of the male member is divided. Therefore, in addition to the function and effect of the second or third problem solving means, if the stopper housing portion in the female member is structured so that the stopper portion does not come out, the male member and the female member are intentionally separated. When trying to do so, since the stop portion remains on the female member, neither the male member nor the female member can be reused, and an anti-falsification effect can be added.

    In addition to the operational effects of any of the first to fourth problem-solving means, the fifth problem-solving means can be attached to the mounted body even when the tip of the stopper is not spire-like and the surface is soft. Not only can this be possible, but the strength in the direction of removal from the locking hole of the stopper after mounting can be increased, so that the operator and other objects are not damaged.

The action of the sixth problem solving means is that, since a space groove is formed around the locking hole of the female member on the side where the male member's stopper is inserted, when the male member's stopper is inserted into the mounted body, Since the return portion of the mounted body formed by perforation by the stop portion can be stored in the space groove on the opposite side (back side) of the attachment portion of the stop portion to the insertion direction, this return portion is located between the stop portion and the locking hole. The insertion resistance of the stop portion is not increased by being sandwiched between them. Therefore, in addition to the operational effects of any of the first to fifth problem solving means, when attaching the resin fixture to the attached body, it can be inserted with a small insertion force. In other words, it can be attached easily.

  Since the action by the seventh problem solving means is that the information recording body is arranged on the male member or the female member, in addition to the action effect of the first to sixth problem solving means, individual information can be managed. it can.

  The action of the eighth problem-solving means is that the information recording body is sandwiched between the resin-made substrate and the exterior part formed by injection molding with a resin fused to the substrate. Since it is covered, the information recording body is reinforced without being brought into direct contact with the outside, in addition to the operational effects of the seventh problem solving means, so that the information recording body can be protected from external forces and water.

  The action of the ninth problem solving means is that the part of the exterior surface of the exterior part is replaced with one surface of the substrate and the information recording body is arranged on the other surface of the substrate. In addition, when the male member or the female member is molded by the injection molding method, the action of the force caused by the molten resin received by the information recording body can be reduced, and the yield of the molded product can be improved.

  The action of the tenth problem solving means is that the information recording body is adhered to the substrate with an adhesive, so that in addition to the action effect of any of the seventh to ninth problem solving means, the arrangement position accuracy of the information recording body In addition, when molding by the injection molding method, the information recording body is not destroyed even if there is a force of the molten resin received by the information recording body, and the yield of molded products is further improved. Can do.

INDUSTRIAL APPLICABILITY The present invention can provide a resin-made fixture that is provided with measures against damage and drop-off prevention that occur when it is inserted into a body to be attached as described above.
Moreover, there exists each effect mentioned above by each aspect.

The meanings of terms used in the present invention are defined as follows. However, terms that are not defined here are treated as terms that have a general meaning.
An information recording medium is a text information, one-dimensional bar code, two-dimensional code, IC tag, etc. that can exchange information in one-way or two-way communication using visual, optical, or radio waves, electromagnetic induction, or magnetic force. Say the body.
The term “resin” refers to all resins that can be fused even if they are different resins as well as the same resins.

The best mode for carrying out the invention will be described below with reference to the drawings.
1 to 4, the male member 101 is formed of a soft resin, for example, an elastomeric resin having a low hardness. The male member 101 basically includes a flange portion 102, a shaft portion 103 extending from the flange portion 102, and a stop portion 104 bulging from the shaft portion 103 at an extended end portion of the shaft portion 103. Yes.
The stopper 104 is formed in a truncated cone shape with the tip end tapered, and on the shaft 103 side, a jaw 104a that is preferably orthogonal to the axis of the shaft 103 is formed. It engages with the locking hole 202.
A reinforcing piece 105 shown in FIG. 3 made of a hard resin, for example, an elastomer resin or a polycarbonate having a high hardness, is provided in the stopper 104 having the outer shape. The reinforcing piece 105 receives a shearing force or the like acting on the stopper 104 when inserted into an attachment body or a locking hole 202 of the female member 201 described later, and serves to prevent the stopper 104 from being broken when inserted. In order to form the wall 105a so as to fulfill, a stepped shape including a large diameter portion 105c and a small diameter portion 105d is formed.
The maximum diameter of the large-diameter portion 105c is smaller than the inner diameter of the locking hole 202 of the female member 201, which will be described later, and the outer peripheral tapered surface of the stopper 104 is formed on the outer peripheral surface of the large-diameter portion 105c on the small-diameter portion 105d side. Chamfering is applied. This is a measure necessary for the stopper 104 to pass through the locking hole 202 of the female member 201, and the outer peripheral taper surface of the stopper 104 and the outer peripheral surface angle of the large diameter portion 105c on the small diameter portion 105d side. This is a measure for preventing the thin-walled portion from being broken when it is inserted into the attachment hole 202 or the locking hole 202 of the female member 201. On the other hand, the thickness between the corner on the shaft 103 side of the large-diameter portion 105c and the stopper base 104b is the force on the opposite side to the insertion direction after inserting into the attachment body or the locking hole 202 of the female member 201, that is, the pulling direction force. When the member acts on the male member 101, the thickness exceeding the desired load is set to an appropriate thickness so that the male member 101 breaks from the stopper root 104b.

Further, a through hole 106 is provided along the axis of the shaft portion 103 in the vicinity of the center portion of the flange portion 102 between the flange portion 102 of the male member 101 and the stop portion 104 via the shaft portion 103. The through-hole 106 is a hole for inserting a mandrel 301 for reinforcing the strength against a buckling load acting on the shaft portion 103 when the male member 101 is driven into a female member 201 described later. The reinforcing piece 105 communicates with the axial wall 105e.
On the other hand, the reinforcing piece 105 passes through a small hole 105b substantially coaxial with the through hole 106, and the through hole 106 is made larger than the small hole 105b. As shown in FIG. 10, the mandrel 301 is shaped to fit into the through hole 106 and the small hole 105b, and the tip 301a of the mandrel 301 is protruded from the tip of the stopper 104, and the protruding tip 301a portion is formed. Is formed in the shape of a spire so that a buckling load to be applied to the shaft portion 103 is received by the step portion 301b of the mandrel 301 via the shaft-side wall 105e of the reinforcing piece 105.
The tip 301a of the mandrel 301 is shaped like a spire so that when the resin member is inserted into the attachment body, the male member 101 is attached to the attachment body, regardless of whether the male member 101 is perpendicular to the attachment body. In the case of being inclined with respect to the body, first, the tip 301a of the mandrel 301 bites into the attached body, so that the male member 101 does not slip on the attached body and the resin fixture can be attached at a desired position. .

In FIG. 1 to FIG. 4, the surface of the flange portion 102 of the male member 101 on the side of the shaft portion 103 is provided with uneven streaky air flow grooves such as an air flow hole 107. The air circulation hole 107 has an air circulation hole 107 even when bleeding due to perforation of the animal ear by the male member 101 when a resin fixture is attached to the animal ear or the like. Will communicate. Therefore, since the wound part damaged by the perforation of the ear of the animal by the male member 101 can be dried, suppuration or the like can be prevented, and the healing effect of the perforated part around the shaft part 103 can be enhanced. Further, as is clear from FIGS. 1 and 2, etc., the air circulation hole 107 is formed in an uneven streak shape, for example, a wavy streak shape in a cross-sectional view. It is formed thinner than. In other words, since the concave portion is easy to bend, even if an animal hits the fence or the like and the hook part 102 is caught on the fence or the like, the hook part 102 is bent and immediately comes off from the fence. Can be prevented.
As described later in paragraph “0048” (see FIG. 16), when the cardboard box 511 or the like is wet when the cardboard box 511 or the like is wet, it is dried due to the presence of the air circulation hole 107. Since the inner part of the collar part 102 is also in equilibrium with the moisture content in the air, it has the effect of maintaining the same characteristics as other parts of the mounted body, and the collar part is easy to bend. Even if the hook is caught on the other article, the male member 101 is easily detached from the other articles due to the bending of the hook, so that the resin fixture can be prevented from falling off.

Next, the female member 201 will be described with reference to FIGS.
The material used for the female member 201 differs depending on the application, but for example, an elastomer resin similar to the male member 101, or a resin such as polypropylene or polycarbonate is used.
First, the substrate 204 will be described. In FIGS. 5 to 7, the substrate body 204a is formed in a donut shape, a plurality of protrusions 204b are disposed on the outer periphery of the upper surface of the substrate body 204a, and the outer periphery of the upper surface of the substrate body 204a. A plurality of holes 204c are formed in the part. A plurality of protrusions 204d are disposed on the inner peripheral portion of the upper surface of the substrate body 204a. These protrusions 204b and 204d are for fixing the substrate 204 in the mold at the time of molding, and the hole 204c allows the resin forming the outer surface of the female member to flow into the hole 204c so that the substrate 204 and the exterior portion This is for further strengthening a portion where the resins forming 201a are joined together in a welded state. In relation to the welding state, if the outer periphery of the substrate main body 204a is formed in a cross-sectional knife shape as shown in FIG. 6, the thin-walled portion at the tip can be easily melted so that the welding can be strengthened.
The back surface of the substrate body 204a is also used to form a part of the boss 205 of the female member 201, and a foot 204e for positioning the substrate 204 during molding is formed. In order to further increase the positioning accuracy of the substrate 204, it is preferable to provide the auxiliary positioning 204f on the downstream side in the flow direction of the molten resin at the time of molding.

  An information recording body, in this embodiment, an IC tag 401 is disposed on the upper surface of the substrate main body 204a. This IC tag 401 has an IC chip 401b mounted on a resin film 401a made of polyethylene terephthalate or the like, and an antenna 401c communicating with the IC chip 401b. The IC tag 401 has an IC tag so as not to be affected by molten resin heat during molding. The top surface of the tag 401 is further covered with a coated paper (not shown) and laminated, and an adhesive (not shown) is applied to the surface of the IC tag on the side of the substrate body 204a to improve the adhesion to the substrate body 204a. Then, the IC chip 401b is considered to be weak against heat by the IC tag 401 to withstand the injection pressure of the molten resin at the time of molding, and by the heat insulating effect by the laminate and the heat radiation effect by the substrate 204 in a room temperature state before molding. It is desirable to take care to protect

Next, the exterior part 201a of the female member 201 will be described with reference to FIGS.
The female member 201 sets the above-described substrate 204 to which the IC tag 401 is bonded in advance in a mold (not shown), and injects the above-described molten resin into the mold (not shown) that forms the exterior portion 201a. By this molding, the large portion 201c, the boss 205, and the storage wall 201d having the locking hole 202, the space groove 203, and the storage hole 201b of the stopper member 104 of the male member 101 are formed.
At the time of molding, the gate position at which the molten resin flows into the cavity is opposite to the IC chip 401b, in this embodiment, opposite to the auxiliary positioning 204f. The IC chip 401b can be protected from the molten resin under pressure. Further, the protrusions 204b and 204d of the substrate 204 are brought into pressure contact with one mold cavity surface of the large portion 201c in the mold, and the surface opposite to the IC tag 401 of the substrate body 204a is pressed against the other mold surface. Thus, a part of the exterior surface of the exterior part is replaced with the surface opposite to the IC tag 401 of the substrate body 204a. This is because when the molten resin that forms the exterior portion 201a of the substrate 204 flows into the mold, the position of the substrate 204 is prevented from changing, and when the IC chip 401b receives the heat of the molten resin. There is also an effect of protecting the IC chip 401b by dissipating heat to the mold through the substrate body.

On the other hand, the retaining hole 202, the space groove 203, and the storage hole 201b of the stopper 104 of the male member 101 will be described. The engaging hole 202 has a smaller diameter than the outer diameter of the stopper 104 of the male member 101. The inner diameter of the storage hole 201b is formed larger than the outer diameter of the stopper 104 of the male member 101.
This is because when the male member 101 is inserted into the female member 201, the outer shape of the stopper 104 is reduced, and when the male member 101 passes through the locking hole 202 and comes out, the outer shape of the stopper 104 is reduced to the original size. In this state, the male member 101 and the female member 201 are coupled with each other.
At this time, the surface of the locking hole 202 perpendicular to the axis on the storage hole 201b side is tapered as shown in FIG. 8 so that the inner peripheral circular portion of the locking hole 202 bulges toward the storage hole 201b. It is good to make a face.
This is because when the male member 101 and the female member 201 are joined, the stop base 104b of the stop 104 of the male member 101 is concentrated on the stop base 104b when a force in the pulling direction is applied to the male member 101. This is because, before the breakage, the shearing stress is applied to the portion having the large cross-sectional area of the stop portion 104 to enhance the removal prevention effect, and the breakage position specifying effect described later can be enhanced.

Further, when the male member 101 is inserted into the mounted body, the space groove 203 is opposite to the insertion surface of the mounted body along the tapered portion of the stopper 104 formed in a truncated cone shape with the tip side tapered. This is for housing the return portion 501a (see FIGS. 11 to 13) bulging to the side.
That is, when the space groove 203 is not provided, the return portion 501a sticks to the inner wall of the locking hole 202. Therefore, when the outer shape of the stopper 104 of the male member is reduced and passes through the locking hole 202, the reduction amount is increased. Therefore, the insertion force when the male member 101 is inserted into the female member 201 is increased accordingly, so the presence of the space groove 203 plays a large role in the sense of improving workability.

Next, an example of using the above-described resin fixture will be described with reference to FIGS.
If the case where the to-be-attached body 501 is an animal ear is demonstrated as an example, the mandrel 301 will be fixed to one side of the pliers-type tool 601, and the male member 101 will be attached to this as shown in FIG.
A holding plate 601a for sandwiching the female member 201 is provided on the other side of the tool 601, and the female member 201 is sandwiched in the posture shown in FIG.
When the tool is held, as shown in FIG. 11, the tip 301 a of the mandrel 301 is first inserted into the animal ear 501, and then the stop 104 of the male member 101 tries to penetrate the ear 501 while drilling.
At this time, as described above, the return portion 501a bulges along the tapered portion of the stopper portion 104 on the side opposite to the insertion surface of the ear 501.
When the return portion 501a is housed in the space groove 203 of the female member 201 and the stop portion 104 further advances in the direction of the lock hole 202, in this embodiment, the maximum outer diameter portion of the stop portion 104 and the space groove 203 Since the inner diameter is substantially the same size, as shown in FIG. 12, the maximum outer diameter portion of the stopper 104 and the inner diameter of the space groove 203 cooperate to cut the vicinity of the base of the return portion 501a, The cut return portion 501 a is stored in the space groove 203. As a result, as can be understood from FIG. 13, when the tapered portion of the stopper 104 reaches the locking hole 202, the return portion 501a is already housed in the space groove 203 and does not exist in the tapered portion of the stopper 104. As shown in FIG. 14, the stopper 104 passes through the locking hole 202 only by being contracted to the same diameter as the inner diameter of the locking hole 202 as shown in FIG. That is, the male member 101 can be inserted into the female member 201 without requiring a large force.

  Then, as shown in FIG. 15, the stopper 104 that has passed through the locking hole 202 is restored to its original size, and the jaw 104 a of the stopper engages with the locking hole 202. This state means the engagement between the tapered portion 104b and the stopper root 104b that causes the inner circumferential circular portion of the locking hole 202 on the storage hole 201b side to bulge to the storage hole 201b side, as described above. When a force is applied to the male member 101 to be removed from the female member 201, the maximum cross-sectional area is obtained at a position within the range of the jaw portion 104a among the tapered stop portions 104 in the sectional view of FIG. Shear will act on this part. That is, it is possible to create a situation in which it is difficult for the male member 101 to come out of the female member 201.

In relation to this action, the force in the withdrawal direction of the male member 101 also acts on the cross section of the stopper 104 between the shortest distance between the stopper root 104b and the large diameter part 105c of the reinforcing piece 105. Here, when viewed from the male member 101, the stress concentrates on the corner on the jaw portion 104a side of the large diameter portion 105c of the reinforcing piece 105 due to the presence of the reinforcing piece 105 that is different in material.
That is, when the male member 101 is separated from the female member 201, the male member 101 breaks from the cross-section of the stopper 104 between the shortest distance between the stopper root 104b and the large-diameter portion 105c of the reinforcing piece 105, which are specific parts. The effect of using this action will be further described in detail in paragraph “0051”.

  Note that the resin fixture of the above embodiment is sealed by reinforcing the IC tag 401 with resin as described above when used for animal management, for example, individual management of pigs and cattle for meat or pet management. For example, in the case of pigs in particular, stable individual management can be achieved even with extremely intense movement for a long time.

  Also, as shown in FIG. 16, when the above-described male member 101 and female member 201 are used with the mounted body being a cardboard box 511 or the like, the IC tag 401 is reinforced and sealed with resin. It is possible to manage the inventory of goods, loading / unloading, movement history, etc. After use, if the male member 101 is cut, the female member 201 containing the IC tag 401 can be reused.

  Furthermore, as shown in FIG. 17, when the attached body is a commodity such as clothes 521, it can be used not only for commodity inventory, loading / unloading, movement history, price management, but also for shoplifting prevention. Also in this case, the female member 201 containing the IC tag 401 can be reused by cutting the male member 101 after use.

  As shown in FIGS. 18 and 19, if display units 118 and 216 are provided on both or either of the male member 111 and the female member 211, characters, numbers, symbols, or the like can be printed on the display unit. Therefore, even if the IC tag 411 breaks down, the information in the IC tag 411 is not lost if the information in the IC tag 411 is linked with characters, numbers, or symbols. Further, due to the presence of the display portions 118 and 216, when used for an animal, even if the portion drilled by the male member 111 becomes larger as the animal grows, it does not fall out.

Furthermore, as shown in FIG. 20, in particular, when the attached body is a cow's ear, it must be prevented from being reused by the above-mentioned law. In this case, the leg 224e portion of the substrate 224 of the female member 221 is In addition to being formed in a cylindrical shape over the entire circumference of the storage hole 221b, the outer side of the storage hole 221b is made uneven to improve the adhesiveness in order to improve the bonding with the exterior part 221a, particularly the storage wall 221d, and in addition, the exterior part 221a So that the bottom portion 221e of the head is completely closed. Then, by making the material of the substrate 224 higher in hardness than the material of the exterior portion 221a and less likely to be destroyed, an act of intentionally releasing the engagement between the male member 121 and the female member 221 cannot be performed. Like that.
As described above, when the male member 121 breaks and separates from the female member 221, it breaks from the cross-section of the stop portion 124 between the shortest distance between the stop portion root 124 b and the large diameter portion 125 c of the reinforcing piece 125. Therefore, the stopper 124 remains in the housing hole 221b of the female member 221, and even if an attempt is made to reuse the female member 221, another male member cannot be inserted and the structure cannot be reused. A suitable resin fixture can be provided.
In the above embodiment, the case where the IC tags 401, 411, 421 are resin-sealed to the female members 201, 211, 221 has been described. However, the IC tags 401, 411, 421 are placed in the male members 101, 111, 121. Resin sealing may be used, or another information recording body may be used instead of the IC tags 401, 411, and 421.
In the resin fixture of the present invention, even if there is no various information recording body, the intended purpose, that is, to solve the conventional problems, typically measures against scratches that occur when piercing the mounted body, etc. The first purpose is to provide a resin-made fixture that can be sufficiently attached to the body to be attached without being dropped off, and can be easily attached to the body to be attached. In addition to being able to achieve the second object of providing a resin fixture, it will be noted that each embodiment has its respective effects.
