Description

  The present invention relates to a lid with an IC tag in which an IC tag storing product information is mounted on the inner surface of a top plate.

  Conventionally, barcodes displaying product information such as date of manufacture, manufacturer / seller name, expiration date, etc. have been widely used for various products. By the way, since barcodes read the coded information with a reader, the barcode printing surface must be flat. For this reason, in the field of packaging materials such as bottles and caps, the barcode printing surface is There is a problem that the amount of information that can be encoded is limited.

  Therefore, recently, an information display technique using an IC tag has been used. An IC tag is also referred to as RFID (Radio Frequency Identification), and is an ultra-high frequency tag formed by embedding an IC chip storing predetermined information in a dielectric material such as resin or glass together with a wireless antenna. It is a small communication terminal. Such an IC tag reads product information stored in an IC chip by wireless communication. For example, data of several hundred bytes can be recorded in a memory of the IC chip, and a lot of product information is stored. There is an advantage that it can be recorded. In addition, IC tags can read information recorded in a non-contact manner, have no problems such as wear due to contact, and can be processed into a shape that matches the form of the product, or can be reduced in size and thickness. There is an advantage that it is possible.

As lid bodies provided with such an IC tag, Patent Documents 1 and 2 have proposed an IC tag embedded in a top plate.

By pulling the liner while holding the knob, or by pushing down the knob, the IC tag can be easily attached to the IC tag without using a special tool by peeling off at least a part of the liner from the inner surface of the top plate. Can be removed from. Therefore, the lid with an IC tag of the present invention has an excellent sorting and discarding property.

The present invention will be described below based on specific examples shown in the accompanying drawings.
FIG. 1 is a side sectional view of a cap which is a representative example of a lid with an IC tag of the present invention.
FIG. 2 is a bottom view of the cap of FIG.
FIG. 3 is a side sectional view showing another preferred example of a cap that is a lid with an IC tag of the present invention,
FIG. 4 is a bottom view of the cap of FIG.
FIG. 5 is a side sectional view showing still another preferred example of a cap that is a lid with an IC tag of the present invention,
FIG. 6 is a bottom view of the cap of FIG.

  1 and 2, the cap denoted by 1 as a whole has a top plate 3 and a cylindrical side wall (skirt portion) 5 that hangs down from the peripheral edge of the top plate 3. An opening history clarification band (TE band) 9 is provided at the lower end of the via a breakable bridge 7.

  A liner regulating ring 11 is formed on the inner surface of the top plate 3. The liner regulating ring 11 extends downward with a small gap from the cylindrical side wall 5 and has a tip bent inward. The liner regulating ring 11 is reinforced by a rib (not shown) extending from the base portion of the cylindrical side wall 5.

  A thread 15 is formed on the inner surface of the cylindrical side wall 5, and this thread 15 engages with a thread formed on the outer surface of a mouth portion (not shown) of a container such as a bottle. It is. That is, the cylindrical side wall 5 is turned in the closing direction (that is, tightened), and the cap 15 is screwed to the container mouth by screwing the screw 15 and the screw on the outer surface of the container mouth. The

  A disc-shaped synthetic resin liner 17 is provided on the inner surface of the top plate 3. The liner 17 includes a sealing portion 20 with a container mouth portion existing on the outer peripheral side, and a tag holding portion 21 on the center side.

  The sealing portion 20 of the liner 17 has an annular outer protrusion 20 a that descends downward at the peripheral edge thereof, and the outer surface of the annular outer protrusion 20 a is in close contact with and held by the inner surface of the liner regulating ring 11. Yes. Further, an inner projecting portion 20b protruding downward is formed at a distance from the annular outer projecting portion 20a. The container is sealed by being fitted and fixed in a recess 20c formed by the portion 20b, and in particular, the inner surface of the annular outer protrusion 20a is in close contact with the outer surface of the container mouth. Of course, the annular outer protrusion 20a and the inner protrusion 20b are not formed, but the peripheral edge of the liner 17 is thick over the entire circumference, and the upper end of the container mouth can be in close contact with the thick wall. The sealing part 20 can also be formed as a shape formed.

  The tag holding portion 21 on the center side of the liner 17 is a portion for holding and fixing an IC tag 30 described later.

  In the cap 1, slits 23 are formed at an appropriate interval in the upper portion of the cylindrical side wall 5 so that the space between the cap 1 and the container mouth can be cleaned.

  A plurality of well-known flexible fins 25 are provided on the inner surface of the TE band 9 at an appropriate interval so that the TE band 9 can be engaged with the jaw formed on the outer surface of the container mouth. . That is, when the cap 1 wound around the container mouth is opened, the fin 25 comes into contact with the jaw portion, and the rise of the TE band 9 is restricted. On the other hand, the cylindrical side wall 5 rises by rotating in the opening direction. Therefore, before the seal due to the close contact between the container mouth and the liner 17 is released, the bridge 7 connecting the lower end of the cylindrical side wall 5 and the TE band 9 is broken, and the TE band 9 is detached from the cap 1. Thus, since the TE band 9 is detached from the cap 1, it is possible to recognize the fact that the cap 1 has been opened once or the seal portion has been broken.

  As shown in FIG. 1, an inner curl 27 is formed on the entire lower end of the TE band 9, and when the fin 25 comes into contact with the jaw of the bottle, this curl When the portion 27 presses the lower portion of the fin 25, the deformation of the fin 25 is suppressed and the TE band 9 is prevented from slipping off.

  In the present invention, as shown in FIG. 1, an IC tag 30 is sandwiched between the inner surface of the top plate 3 and the tag holding portion 21 of the liner 17. As described above, the IC tag 30 has an IC chip on which a lot of product information such as the liquid in the container (manufacturing date, manufacturer / seller, expiration date, etc.) is recorded and the radio antenna is made of resin, It is embedded in a dielectric material such as glass, and its shape is not particularly limited as long as it can be sandwiched between the top plate 3 and the liner 17, but is usually preferably circular. Further, the thickness is preferably not a film shape but a thickness that can keep the shape to some extent.

  The IC tag 30 as described above is held on the inner surface of the top plate 3 by the tag holding portion 21 of the liner 17 formed so as to surround the IC tag 30.

  By the way, the IC tag 30 as described above is required to be removed from the cap 1 and disposed of separately when the cap 1 is discarded. In the present invention, for this purpose, as understood from FIG. 2, an arc-shaped tear score 31 is formed at the boundary portion between the sealing portion 20 and the tag holding portion 21 of the liner 17, and at the same time, the central portion of the score 31. A pole-shaped knob 33 projecting downward is formed on the center portion of the liner 17. That is, when the used cap 1 is removed from the container mouth and discarded, the tear score 31 is broken by pushing down the knob 33 of the liner 17 to the side where the tear score 31 is not formed. By pulling up the knob 33, the portion surrounded by the tear score 31 is peeled off from the inner surface of the top plate 3, thereby removing the IC tag 30 sandwiched between the liner 17 and the top plate 3. It becomes possible.

  In the present invention, the above-mentioned arc-shaped tear score 31 only needs to have such a length that the IC tag 30 being held can be easily pulled out by hand when it is broken. For example, in the above example, the tear score 31 is formed in an arc shape, but it is of course possible to form it in a ring shape.

  In the above example, the knob 33 is formed at the center of the liner 17 (the center of the cap 1). However, the knob 33 can be formed at a position close to the score 31 by decentering this position. . Furthermore, the shape of the knob | pick part 33 is not made into a pole shape, but it can also make it easy to push down the knob | pick part 33 as a rectangular plate shape.

  Furthermore, in the present invention, the tear score 31 as described above is not formed, only the knob 33 is formed, and the knob 17 is pulled up so that the liner 17 is peeled off from the inner surface of the top plate 3. Is possible. However, in the case of such a structure, means such as selecting a material having poor adhesion to the resin forming the cap 1 as the material of the liner 17 or blending a large amount of lubricant in the liner 17. It is necessary to adopt and make the liner 17 and the top plate 3 easily peelable.

  In the present invention, a tear induction score may be provided separately from the score 31 so that the tear score 31 is easily broken by pushing down the pole-shaped knob 33 described above. it can. FIGS. 3 and 4 show a side sectional view and a bottom view of the cap in such a mode, respectively.

  3 and 4, in the cap 1, the tear score 31 described above is formed in a ring shape, and the end line shape extends so as to partially wrap around the base of the pole-shaped knob 33. The tear induction score 35 (see particularly the bottom view of FIG. 4) is provided. That is, as is apparent from FIG. 4, the one end portion 35a of the tear induction score 35 is located on the inner side of the ring-shaped tear score 31, and the knob 35 starts from the end portion 35a. 33 extends linearly toward the base of the knob 33, and extends so as to be substantially line symmetric with the straight line from the end 35a to the knob 33. And ends at the other end 35 b located on the tear tear score 31. (The cap 1 shown in FIGS. 3 and 4 has the same basic structure as the cap 1 shown in FIGS. 1 and 2 except that such a tear induction score 35 is formed. 3 and 4 use the same imprinting numbers as in FIGS. 1 and 2.)

  That is, by providing such a tear induction score 35, when the knob 33 is pushed down, the score 35 is broken, and the region surrounded by the score 35 is peeled off from the inner surface side of the top plate 3, and as a result, The tear score 31 can be easily broken by holding the peeled portion having the knob 33, and the IC tag 30 can be removed together with the liner holding portion 21.

  Further, in the above aspect, only the one end portion 35a is located on the inner side of the tear score 31, and the other end portion 35b is located on the inner side of the tear score 31 in the same manner as the one end portion 35a. It can also be located. Also in such an embodiment, the picking portion 33 is pushed down, the score 35 is broken, the region surrounded by the score 35 is peeled off from the inner surface side of the top plate 3, and then the peeling portion having the picking portion 33 The IC tag 30 can be removed together with the liner holding portion 21 by pulling it up.

  The opening angle θ (see FIG. 4) of the above-described tear induction score 35 is preferably in the range of 15 to 40 degrees. If the opening angle θ is larger than the above range, the tear induction score 35 is less likely to break when the knob 33 is pushed down. If smaller than the above range, the tear induction score 35 is derailed and broken. This is because there is a risk that the region where the knob portion 33 is formed may be completely removed.

  In the example of FIGS. 1 to 4 described above, an example in which the sealing portion 20 with the container mouth portion is formed on the liner 17 is shown. However, in the present invention, the sealing portion is not formed on the liner 17 and the cap 1 It is also possible to provide a sealing portion on the top plate 3 of this type, and such a cap is shown in FIGS.

  That is, in the cap 1 shown in FIGS. 5 and 6, an inner ring 50 is formed on the inner surface of the top plate 3 at a distance from the cylindrical side wall, and on the outer side, the inner ring 50 is located behind the inner ring 50. A lower outer ring 51 is formed, and a small protrusion 53 is formed between the inner ring 50 and the outer ring 51. That is, when the cap 1 is attached to the container mouth by screw engagement, the upper end portion of the container mouth rises into the space between the inner ring 50 and the outer ring 51. At this time, since the inner surface of the outer ring 51 contacts the outer surface of the upper end portion of the container mouth portion, the centering of the cap 1 is performed, and the cap 1 is concentrically rotated without screwing. As a result, the upper end portion of the container mouth portion penetrates deeply into the space between the inner ring 50 and the outer ring 51, and the outer surface of the inner ring 50 is in close contact with the inner surface of the upper end portion of the container mouth portion to form a sealed portion. The At this time, since the small protrusion 53 contacts the upper end surface of the container mouth portion, excessive winding is effectively prevented.

  In the cap 1, the TE band 9 is provided with an upward protruding piece 55 on the inner surface of the TE band 9 instead of the flexible fin. It abuts on the lower side of the jaw and restricts the rise of the TE band 9, and has exactly the same function as the flexible fin 25 in FIG.

  In the cap 1 as described above, the liner 57 is provided on the inner surface of the top plate 1. The liner 57 is provided inside the inner ring 50, and the inner ring 50 forms a sealing portion. Therefore, the sealing portion 20 formed on the liner 17 of the cap 1 shown in FIGS. 1 to 4 is not formed on the liner 57. In other words, the liner 57 has substantially the same structure as the tag holding portion 21 in the liner 17 of the cap 1 shown in FIGS. 1 to 4. Like the tag holding portion 21, the liner 57 and the top surface are provided. 3, the IC tag 30 is sandwiched and surrounded by a liner 57, and a pole-shaped knob 33 is formed at the center of the liner 57.

  In the cap 1 of this embodiment, the liner 57 is formed with a tear score 59 having the same shape as the tear induction score 35 in the cap 1 shown in FIGS. 3 and 4 described above. That is, the score 59 has an end line shape extending so as to partially wrap around the base of the pole-shaped knob 33, and one end 59a of the tear score 59 is It is located on the inner side of the outer peripheral edge, extends linearly toward the knob 33 starting from the end 59a, wraps around the base of the knob 33, and further includes an end It terminates at an end 59b on the other side located on the outer peripheral edge of the liner 57 so as to be substantially line symmetrical with the straight line portion from 59a to the knob 33.

  Therefore, when the knob portion 33 is pushed down, the score 59 is broken, and the region surrounded by the score 59 is peeled off from the inner surface side of the top plate 3, and then the portion peeled off together with the knob portion 33 is picked and pulled up. Thus, the IC tag 30 can be removed together with the liner 57.

  Even in such a tear score 59, only one end 59a is positioned inside the outer peripheral edge of the liner, but the other end 59b is closer to the outer peripheral edge of the liner, like the one end 59a. Can also be located inside. Also in such an embodiment, the picking portion 33 is pushed down, the score 59 is broken, the region surrounded by the score 59 is peeled off from the inner surface side of the top plate 3, and then the peeling portion having the picking portion 33 The IC tag 30 can be removed together with the liner 57 by pulling it up. Further, when the score 59 is broken by pushing down the knob 33, the opening angle θ is preferably in the above-described range so that the break line does not derail from the score 59 and is easily broken.

  The cap 1 of the present invention having the structure shown in FIGS. 1 to 6 is formed such that the main body of the cap 1 is molded by injection molding using various thermoplastic resins, and then the IC tag 30 is sandwiched therebetween. The liner 17 or the liner 57 made of a relatively soft resin or elastomer is provided. For example, the IC tag 30 is placed on the inner surface of the top plate 3 of the cap body molded into a predetermined shape, and in this state, the melted liner material is dropped and embossed to form the liner 17 or the liner 57. it can. Alternatively, the liner 17 can be provided by applying an adhesive to the outer region of the score 31 of the liner 17 that has been previously molded into a predetermined shape, and adhesively fixing it to the inner surface of the top plate 3 with the IC tag 30 interposed therebetween. . Furthermore, as the resin used for the liner material 17 or the liner material 57, a resin containing an oxygen absorbent may be used.

  Further, in the present invention, as shown in FIGS. 3 to 6, an IC chip 60 having a curvature surface is formed in the central portion of the IC tag 30, and the IC chip 60 is connected to the liner 17 or 57 side. In addition, it is preferable to position it at a portion corresponding to the knob portion 33. That is, by forming in this way, it is possible to prevent an excessive load from being applied to the IC chip 60 when the liner 17 or 57 is provided, and to effectively prevent breakage of the IC chip 60 when the liner is formed. be able to.

  In the present invention described above, removal of the IC tag 30 from the cap 1 can be quickly performed without using a special tool, and excellent sorting and disposal can be ensured.
