referring now to the accompanying drawings , the tag of the present invention includes a main body portion 2 and a strap portion 3 . the tag is preferably formed of an appropriate plastics material , or some other flexible or semi - flexible material . other materials can however be used to an advantage . the main body portion 2 includes a main indicia section 4 such as shown in the accompanying drawings , this being integrally formed with a downwardly extending shank 5 , extending downwardly from the indicia section 4 . in one form of the invention , suitable wings 6 extend and curve slightly downwardly from a rear side of the indicia section 4 to each side of the upper portion of the elongate shank 5 . the indicia section 4 includes a lower end 4a which cooperates with the shoulder 10 to lock the strap 3 on the shank 5 . in one form of the invention and as will be described hereinafter , the shank 5 is provided with a closed and pointed end 7 , and may be substantially hollow in formation with an elongate bore 8 , such as to allow for the location of a driving pin or driving member ( not shown ) such as is associated with an applicator tool for applying a tag to the ear of an animal . in this way the applicator pin does not come into contact or penetrate the animal &# 39 ; s tissue thus reducing the risk of cross - infection between animals . thus , in the preferred form of the invention , the shank 5 is substantially hollow and closed at its bottom end . the shank 5 is preferably substantially circular in cross - section , and is elongate in formation , the connection from the main body portion 4 slanting or tapering down ( such as at 10 ) into the elongate shank 5 . the head 7 of the shank 5 is shown pointed and having an upper ridge or flange portion 7a of a greater diameter than the shank 5 , so that it extends outwardly around the bottom of the shank 5 . the outwardly extending annular flange 7 a then extends into the pointed end 7 . referring further to the accompanying drawings , an upper portion of the elongate shank 5 is provided with a radially outwardly extending tab or engagement member 12 , which , serves to engage with a corresponding slot or recess 14 in annular surround of a bore 20 at one end of the strap 3 . referring to the strap 3 shown in the accompanying drawings , it will be appreciated that the strap is of an elongate formation , having a hole or bore at each end thereof . the surface 29 about the bore 20 at the first end of the strap is shown slightly tapered at its upper end . if desired a plurality of such slots can be provided to engage with one or more tabs 12 . the lower portion of the tab 12 is shown provided with a locking key 12a which is engageable within a key way provided between reinforcing flanges 28 on the underside of the strap 3 , the key way being the lower extension of the recess 14 . the upper end of the strap thus becomes locked between the shoulder 10 and the lower end 4a of the indicia - bearing section on one side of the strap and an upwardly facing shoulder defined by the locking key 12a on the other side of the strap . the first end of the strap 3 also engages with and under the bottom of the indicia section 4 so that it is engaged firmly relative to the body portion . if desired , a plurality of outwardly extending engagement members 12 , and / or engagement slots or grooves 14 can be provided in both the body portion 2 and the strap 3 , to allow for positive engagement between the body portion and the strap . the above however is the preferred form of the invention . with the tag 2 engaged with the strap 3 there are no 90 degree flanges or inverted steps under which a wire can snag resulting in the tag 2 being pulled off . also to prevent wire snagging the sides of the tag 2 are shown suitably angled so that there are no steps or flanges above the ear . it should be appreciated also that other locating means can be provided , in association with one or more of the shank and the strap , to allow for positive location therebetween . the second end of the strap is also provided with a bore or hole 21 passing therethrough and this can have a tapered lead - in portion formed in the annular surface of the bore 21 as shown in the accompanying drawings . referring now to the engagement of the pointed end of the shank 5 , with the second end of the strap 3 , the pointed end 7 is caused to in use to pass downwardly into the bore 21 at the second end of the shank 3 , and such a driving action or friction will cause it to exit from the bore 21 . the upper surface portion 7b of the end of the shank 5 forms an upwardly facing shoulder so dimensioned that the end 7 ( and flange 7a ) are unable to be withdrawn out of the bore 21 . in use , the first end of the strap is engaged over and about the shank 5 ( the shank passing through the bore 20 ), and the strap is then folded into a substantially flattened &# 34 ; c &# 34 ; shape so that the bores 20 and 21 are spaced apart , but substantially aligned or co - axial . in this position the shaft 5 is caused to be driven or moved downwardly ( such as by an applicator tool ) and through the hole or bore 21 in the second end of the strap 3 to be firmly engaged within the bore 21 at the second end of the strap 3 ( as referred to hereinbefore ). by way of example only , a tag may be applied to the ear of an animal and the first end of the strap is therefore engaged with and about the elongate shank 5 . the main body portion 2 and the attached first end of the strap 3 are then engaged within an appropriate applicator tool . for example , an applicator pin emerges within the bore 8 of the hollow shank 5 . the remainder of the strap 3 is then bent or curved over into a substantially flattened &# 34 ; c &# 34 ; formation , so that the bore 21 at the second end of the strap 3 is located in a position in which it is spaced apart from , and underneath the pointed end 7 of the shaft 5 and substantially aligned or co - axial with the bore 20 in the first end of the strap 3 . for example the second end of the strap can be located on appropriate location means in an applicator tool . the applicator tool ( not shown ) which can for example include spaced apart jaw members and handles , which are normally spring biased apart , is then placed over the ear of an animal so that the strap is in a substantially flattened &# 34 ; c &# 34 ; configuration , extending about an edge of the ear of an animal , the main body portion and indicia section extending upwardly therefrom . as indicated , the applicator or pin or an applicator tool has already been engaged within the hollow bore 8 in the shank 5 of the body portion 2 . the applicator tool is then actuated such as by the handles and jaw members being brought together against the bias of the spring , this causing the pin or locating member engaged within the shank 5 to drive the shank 5 downwardly through the ear of an animal and through the substantially co - axial and aligned bore 21 in the second strap 3 . the pointed end 7 of the shank 5 is substantially prevented from being withdrawn by the engagement of the underside of the strap 3 about the bore 21 with the flange 7a . the design of the bore 21 is such as to facilitate the entry of the end 7 but to ensure locking after entry . moreover the size of the bore 21 may be such that the size of the plug of skin and cartilage punched out is maximised . this results in earlier healing of the wound and reduces the chance of infection . by locating , moving or rotating the main body portion and shank relative to the groove 14 , the engagement tab or member 12 of the shank 5 can engage within the recess or groove 14 in the annular surface of the bore 20 at the first end of the strap 3 , so as to prevent movement of the main body portion 2 and in particular the indicia section 4 to which appropriate identification means can be attached if required . the identification means is thus positively located relative to the ear of the animal and to the supporting and locating strap 3 to maintain its high visibility . it should be appreciated that improvements and modifications may be made to the invention without departing from the scope or spirit thereof .
an identification tag to be attached to an animal &# 39 ; s ear includes a body and a strap . the body includes a shank adapted to be driven through the animal &# 39 ; s ear and through a bore in the strap by means of a tool , and an indicia - bearing section formed integrally with the shank . the shank includes a downwardly extending hole for receiving a driving portion of the tool . the indicia - bearing section projects upwardly from a location spaced laterally of the hole to avoid interfering with entry of the tool into the hole . the shank and strap include interengaging surfaces which prevent relative separation and relative rotation therebetween .
