Description

  The present invention relates to a composite container lid with an IC tag, and more particularly to a composite cap that cannot read information of an IC tag or can change recording information after the cap is opened.

  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.
For example, Patent Document 1 discloses a cap in which an IC tag is embedded in a top plate.

It has also been proposed to use such an IC tag for displaying the opening history of a container. For example, Patent Document 2 ties an IC chip in an IC tag and an antenna when the cap is opened. A method has been proposed in which opening is detected when a lead wire is disconnected.
Moreover, in patent document 3, when the upper cover connected with the cap main body with which a container opening part is attached is opened, the antenna circuit provided in the cap main body is cut | disconnected, and this can recognize the fact of opening. It is disclosed.

  In both of these Patent Documents 2 and 3, it is possible to recognize the fact of opening by detecting the fact that the circuit of the IC tag is disconnected by an external reader, but there are still problems to be solved. Has been.

For example, in the technology proposed in Patent Document 2, an IC chip of an IC tag is provided on a container body or a portion belonging to the container body (specifically, a tamper evidence band cut off from a cap at the time of opening). An antenna and a lead wire are provided on a cap to be screwed, and the lead wire is broken when the cap is opened.
However, when the IC chip is provided in the container body, the antenna and the lead wire for connecting the IC chip and the antenna are provided in a cap separate from the container, but such a configuration is difficult to implement. Good. That is, an IC tag in which an antenna and an IC chip are connected by lead wires is provided on the cap, and after the cap is attached to the container mouth portion, only the IC chip portion is attached to the container side. However, the cap must be attached to the container mouth portion with the IC chip hanging down, and the operation (capping) becomes extremely difficult, and the IC chip is easily broken or the lead wire is easily cut at the time of capping. . Furthermore, it is not easy to attach the IC chip hanging from the cap to the container.

In the means of Patent Document 3, the IC tag is provided on the outer lid material provided separately from the lid material sealing the container mouth, and the opening operation of the lid material sealing the container mouth is The IC tag destruction operation using the outer lid member provided with the IC tag is performed completely separately. Therefore, after removing the outer lid member provided with the IC tag, the lid member sealing the container mouth must be opened.
That is, in the cited document 3, in order to open the container mouth, it is necessary to remove the lid (outer lid) to which the IC tag is attached separately from this operation. There is a drawback in that it takes time to open the bag, and further improvement is required.

Furthermore, the known means of Patent Documents 2 and 3 have a problem that the use of the IC tag is limited because the information stored in the IC chip cannot be read after opening.
In particular, when the contents of the IC tag can be confirmed after the cap is opened, if the information on the campaign such as the product, whether or not the prize is won, or the material of the cap is recorded, sorting of the recycling becomes possible.

JP 2005-321935 A Patent 4047821 JP 2011-213378 A

Hereinafter, a first embodiment of a composite cap with an IC tag according to the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of the composite cap according to the present invention before opening, FIG. 2 is an exploded perspective view of the composite cap, and FIG. 3 is a broken perspective view of the overcap of the composite cap. FIG. 4 is a perspective view of the intermediate member, and FIG. 5 is a perspective view of the IC tag.
The composite cap 1 includes an overcap 2 disposed on the outer side, an inner cap 3 disposed on the inner side, an intermediate member 4 disposed between the overcap 2 and the inner cap 3, and an overcap 2 and an intermediate member. 4, and an IC tag 5 disposed between the two.

The resin overcap 2 includes a top wall panel 7 having a circular top surface and a skirt wall 8 descending from the periphery of the top wall panel 7. A circular push plate 9 is provided at the center of the top wall panel 7. The push plate 9 is surrounded by a broken portion 18 provided with a plurality of slits by a cutter or the like. The breaking portion 18 is provided with the bridging portions 10 formed at equal intervals, and the push plate 9 is pushed downward to break the bridging portion 10, and the push plate 9 is broken from the overcap 2. On the lower surface of the push plate 9, a plate-like cutter 11 that extends radially outward from the center side and protrudes downward is formed.
A rupture line 12 extending in the circumferential direction is formed at a lower portion of the cylindrical skirt wall 8. A main portion 15 is defined above the rupture line 12, and a tamper evidence skirt portion 13 is defined below. A plurality of bridging portions 14 are formed in the breaking line 12 at intervals in the circumferential direction.
On the inner peripheral surface of the main portion 15 of the skirt wall, an anti-slip inner knurl 16 is formed which is formed of uneven shapes alternately present in the circumferential direction. A plurality of flaps 17 projecting upward on the inner circumferential side of the overcap 2 are formed at equal intervals on the inner circumferential surface of the tamper evidence skirt 13.

  The inner cap 3 made of resin has a circular upper wall panel 19 and a female screw 22 that descends from the peripheral edge of the upper wall panel 19 and that is threadedly engaged with the outer surface of the mouth neck portion 21 of the container 6 on the inner surface. It consists of the cylindrical wall 20 provided with (FIG. 1). On the outer peripheral surface of the cylindrical cylindrical wall 20, an anti-slip outer knurl 23 composed of uneven shapes alternately present in the circumferential direction is formed. Between the upper wall panel 19 of the inner cap 3 and the cylindrical wall 20, an annular inclined surface (conical) surface 24 having a relatively small length and facing downward in the radial direction is formed.

  The resin intermediate member 4 shown in FIGS. 4A and 4B includes a top plate 26 to which the IC tag 5 is attached, and a peripheral wall 27 lowered from the periphery of the top plate 26. A slit-like concave groove (hole) located directly below the cutter 11 formed on the push plate 9 of the overcap 2 with the composite cap 1 assembled to the outer side in the radial direction from the center of the top plate 26. ) 28 is formed. An annular convex portion 30 is formed around the top plate 26, and a peripheral wall 27 is formed below the annular convex portion 30. The peripheral wall 27 is formed with slits 31 such as notches and grooves formed from the lower end of the peripheral wall 27 toward the upper side of the peripheral wall 27. In the present embodiment, the slit 31 is formed by a vertical groove in which the thickness of the peripheral wall 27 is reduced. The longitudinal cross-sectional shape of the peripheral wall 27 is a substantially isosceles triangular shape with a narrow lower tip and thicker toward the bottom surface of the upper wall panel 19.

On the top plate 26 of the intermediate member 4, a film-like IC tag 5 is stuck.
An IC tag 5 shown in FIG. 5 includes a thin film base 33 made of resin having a circular thickness, an IC chip 34 having a recording medium, and an antenna 35 for transmitting and receiving information connected to the IC chip 34.
The film substrate 33 is generally formed from a thermoplastic resin that can be thermally welded. The thermoplastic resin is not particularly limited, but generally, the same resin as the resin base material constituting the overcap 2 and the inner cap 3 to which the IC tag 5 is attached is used. For example, when the IC tag 5 is provided on a polyolefin cap, the film substrate 33 is preferably formed of polyolefin. In addition, there is an IC tag 5 that is commercially available with the IC chip 34 and the metal antenna 35 provided on a polyethylene terephthalate resin film. In such a case, an adhesive such as an acid-modified olefin resin is appropriately used. It is preferable that a polyolefin resin layer such as polyethylene or polypropylene is laminated on the back surface of the polyethylene terephthalate resin film substrate 33 in terms of attaching the IC tag 5 to the cap.
Moreover, as the film base material 33, paper can also be used.

The IC chip 34 is provided so as to be electrically connected to the antenna 35 by flip chip mounting or the like, and stores information regarding a product to which the IC tag 5 is attached. By transmitting all the signals, predetermined information is stored, and information stored in the IC tag 5 is read via the antenna 35.
The IC chip 34 is generally sealed and protected by an electrically insulating cured resin such as polyimide or bismaleimide resin. Further, the IC chip 34 can be sealed by bonding paper.
As described above, the IC chip 34 has information on the contents filled in the packaging container (eg, producer, manufacturer, production date, shipping date, etc.), information on the container, and the campaign. Have been entered. Such information is input and output by a high-frequency signal, and generally a UHF band near 900 MHz and a frequency band of 13.56 MHz are mainly used.

The antenna 35 used for transmitting / receiving a signal to / from the IC chip 34 has a resonance length corresponding to the frequency of the signal used. The antenna 35 is usually made of a low-resistance metal thin film (thickness of about 5 to 50 μm) such as aluminum, copper, silver, or gold. For example, the metal foil is bonded or plated, etched, or conductive such as silver paste. It can be formed by printing using a reactive ink.
Note that the thickness of the film base material 33 may be any thickness as long as it exhibits such a strength that the work for mounting the IC chip 34 on the surface or the plating work for forming the antenna 35 can be performed. It can be set to an appropriate thickness according to the mounting form. For example, when the film base 33 is attached to the cap by heat sealing on the back surface (the surface on which the IC chip or the like is not provided) or on the surface where the metal antenna is not present, it may be relatively thin. When the cap is attached by fitting or the like, it is necessary to make it relatively thick. From such a viewpoint, the thickness of the film base material 33 is generally set to a range of about 5 to 1000 μm, and within this range, it is preferable to set the thickness according to the mounting form.
In FIG. 5, the film base material 33 has a disk shape. However, the film base material 33 may have an appropriate shape according to the attachment form, the break position of the circuit, etc., and does not have to be circular. .

  The IC chip 34 is disposed between the center and the outer periphery of the film base material 33. At the side of the IC chip 34, both end portions of the antenna 35 are connected to the IC chip 34 by being bent toward the IC chip 34 side. The antenna 35 is double-arranged inside and outside along the outer peripheral portion of the film base 33, is substantially circular on the inside, and has an arc shape that is divided into two on the outside. A part of the antenna 35 is arranged immediately below the cutter 11 and on the groove 28 so as to be divided.

As shown in FIG. 1, when the composite cap 1 is assembled, a gap that is the same as or slightly narrower than the height of the intermediate member 4 is provided between the top wall panel 7 of the overcap 2 and the upper wall panel 19 of the inner cap 3. Is formed. A slight gap 43 is formed between the skirt wall 8 of the overcap 2 and the cylindrical wall 20 of the inner cap 3. On the other hand, it is preferable that the inner diameter of the distal end portion of the peripheral wall 27 of the intermediate member 4 is sized so that the distal end portion is placed on the inclined surface 24 of the inner cap 3. As described above, the intermediate member 4 is disposed between the top wall panel 7 and the upper wall panel 19, and is accommodated such that the distal end portion of the peripheral wall 27 is placed on the outer peripheral portion of the upper wall panel 19.
The width of the gap 43 is formed to be larger than the thickness of the distal end portion of the peripheral wall 27 and slightly smaller than the base end side of the peripheral wall 27. Therefore, when the intermediate member 4 is pressed downward, the intermediate member 4 is pressed downward, so that the gap of the slit 31 formed in the peripheral wall 27 opens to the outside, and the distal end portion is inserted into the gap 43, and the peripheral wall 27 itself is sandwiched between the skirt wall 8 and the cylindrical wall 20.

The container 6 to which the composite cap 1 is assembled has a male screw 40 on the mouth and neck portion 21 thereof. The male screw 40 is screw-engaged with the female screw 22 formed on the inner peripheral portion of the inner cap 3. A locking jaw portion 41 that protrudes outward in a ring shape is formed at the lower portion of the mouth and neck portion 21.
In the state where the composite cap 1 is mounted on the mouth-and-neck portion 21, the flap 17 formed on the inner peripheral surface of the tamper-evident hem portion 13 of the overcap 2 is locked to the lower surface of the locking jaw portion 41, and the overcap 2 The cap 2 is prevented from coming off.

  An example of attaching the composite cap 1 to the container 6 is as follows. First, the inner cap 3 is attached to the mouth and neck portion 21 in advance by screw engagement, and then the tip of the intermediate member 4 is connected to the upper wall panel 19 of the inner cap 3. Overlay so that it is placed on. At this time, the tip of the peripheral wall 27 of the intermediate member 4 is placed on the inclined surface 24 (FIG. 2) of the inner cap 3. Although the IC tag 5 is attached to the intermediate member 4 in advance, it may be attached with an adhesive, and the film base 33 of the IC tag 5 can be attached to the upper surface of the upper wall panel 19 by heat welding.

Then, the overcap 2 is placed on the inner cap 3 and the intermediate member 4. In the overcap 2, when the flap 17 formed on the tamper evidence skirt 13 gets over the locking jaw 41, the tip of the flap 17 is locked to the bottom surface of the locking jaw 41 and the flap 17 is prevented from coming off. . At this time, the intermediate member 4 can be prevented from rattling of the overcap 2 together with the intermediate member 4 by being sandwiched vertically between the top wall panel 7 and the upper wall panel 19.
The push plate 9 may be affixed with a seal for hiding the fractured portion 18, and the seal may include a description of how to open the cap and a note regarding reading of the IC tag. .

Next, the effect | action of embodiment in the composite cap with an IC tag of this invention is demonstrated.
Product information and the like are recorded in the IC tag 5 in advance. For example, basic product information such as the date of manufacture of the beverage, which is the contents of the container 6, the place of production, the expiration date, and the opening history information, and other campaign information can be recorded. Furthermore, when the container is not a beverage or food, for example, if it is a detergent, it is possible to record the usage method and notes. Therefore, when purchasing the container 6, the user can know the product information with a reader provided at the store or a reader such as a mobile phone.

When the user opens the composite cap, first, the push plate 9 of the overcap 2 is pushed from the unopened state of FIG. The push plate 9 is broken along the breaking line. Since the cutter 11 is provided on the bottom surface of the push plate 9, the cutter 11 breaks through the film substrate 33 as shown in FIG. Since the antenna 35 passes directly under the cutter 11, the antenna 35 is cut. A concave groove 28 is formed in the top plate 26 of the intermediate member 4, and the cutter 11 can bite into the concave groove 28 and the antenna 35 can be easily cut. In order to make it easier to cut, the film base material 33 may be cut by positioning the antenna 35 on both the left and right sides of the portion (position) to be cut.
In order to protect the IC chip 34, the height of the cutter 11 is made larger than the depth of the groove 28, and a gap that is thicker than the IC tag 5 is formed between the push plate 9 and the top plate 26. deep.
Thus, a part of the antenna 35 is disconnected, and communication with the reader becomes impossible. Therefore, since the IC tag 5 cannot communicate with the one opened for the purpose of mischief when the user picks up the container, the user knows that the cap is opened.

As shown in FIG. 6B, when the push plate 9 is broken and the push plate 9 pushes the top plate 26 of the intermediate member 4, a slit 31 is formed in the peripheral wall 27 of the intermediate member 4. The peripheral wall 27 enters the gap 43 between the skirt wall 8 and the cylindrical wall 20 by increasing the diameter of the slit 27 at the thin portion of the slit 31. The front end portion of the peripheral wall 27 is placed on the inclined surface 24 of the inner cap 3, and the inclined surface 24 is guided to the gap 43 along the lower side.
The cross-sectional shape of the peripheral wall 27 is thin like a wedge and thin toward the upper side, and the peripheral wall 27 fills the gap 43 in the upper part, and the peripheral wall 27 is formed between the skirt wall 8 and the cylindrical wall 20. It is sandwiched between. Therefore, the overcap 2, the inner cap 3, and the intermediate member 4 are integrally fixed via the peripheral wall 27 sandwiched between them. In particular, an inner knurl 16 for preventing slipping is formed on the inner peripheral surface of the skirt wall 8, and an outer knurl 23 is formed on the outer peripheral surface of the cylindrical wall 20. Thus, since the peripheral wall 27 is formed between the inner and outer knurls 16 and 23 for preventing slipping, the peripheral wall 27 is firmly fixed in the rotational direction of the composite cap without slipping.
When the composite cap 1 is rotated in such a state, the inner cap 3 moves up the mouth-and-neck portion 21 by screw engagement with the container 6. The overcap 2, the inner cap 3 and the intermediate member 4 rise together, but the tamper evidence skirt 13 has the flap 17 locked to the locking jaw 41, so the breaking line 12 is cut. Thus, the composite cap 1 (excluding the tamper evidence skirt 13) can be integrally opened.

A locking claw is formed so that the intermediate member 4 does not return upward when the intermediate member 4 is pushed in, and a hooking portion of the locking claw is formed on either the overcap 2 or the inner cap 3. The intermediate member 4 may be prevented from returning (not shown).
In the present embodiment, since the tamper evidence skirt 13 is formed, the flap 17 is locked to the locking jaw 41 and the breaking line 12 is cut. The tamper evidence skirt 13 may use, for example, a tear band that tears the bridging portion with a knob without accompanying the rotation of the cap, instead of the tamper evidence band.

  The user can confirm the date of manufacture and the expiration date of the product at the time of purchasing the container 6 or after purchase with a reading device such as a mobile phone. Further, information that the composite cap 1 is still unopened can be confirmed, and mischief such as exchange of contents after opening is recognized and prevented.

Next, a second embodiment of the present invention will be described with reference to FIGS.
In the present embodiment, only the shape and position of the cutter formed on the IC tag and the push plate are different from those of the first embodiment, but the same names as those of the first embodiment are the same. This will be described with reference numerals. Further, parts not specifically described have the same configuration as that of the first embodiment.
In the present embodiment, the resin overcap 2 is provided with a circular push plate 9 at the center of the top wall panel 7, and a cutter 11 projecting downward in a conical shape on the lower surface of the center of the push plate 9. Is forming.
The resin-made intermediate member 4 shown in FIGS. 8A and 8B includes a top plate 26 to which the IC tag 5 is attached, and a peripheral wall 27 that is lowered from the periphery of the top plate 26. In the central portion of the top plate 26, a conical concave groove (hole) 28 is formed directly below the cutter 11 formed in the push plate 9 of the overcap 2 with the composite cap 1 assembled. doing.

The IC tag 5 shown in FIG. 7 includes a thin film base 33 made of resin, an IC chip 34 having a recording medium, and an information transmission / reception antenna 35 connected to the IC chip 34. The IC chip 34 is provided with a cutting circuit 36 having a lead wire 37.
The lead wire 37 passes from the one end of the IC chip 34 through the center side of the film substrate 33 and is connected to the other end side of the IC chip 34. The cutting circuit 36 can detect whether or not the lead wire 37 has been cut by cutting the lead wire 37 and causing an electrical change before and after the cutting of the lead wire 37.
Since the lead wire 37 is cut by the cutter 11 formed on the bottom surface of the push plate 9 described above, it is important to pass under the cutter 11 or to be arranged at a position where it is effectively cut by the cutter 11. It is. In this embodiment, since the cutter 11 is located in the center part of the overcap 2, it is necessary to arrange any part of the lead wire 37 in the center. Thus, by positioning the cutting part and the cutter 11 at the center part, it is not necessary to align.

Next, the effect | action of embodiment in the composite cap with an IC tag of this invention is demonstrated.
Product information and the like are recorded in the IC tag 5 in advance. For example, basic product information such as the date of manufacture of the beverage, which is the contents of the container 6, the place of production, the expiration date, and the opening history information, and other campaign information can be recorded. Furthermore, when the container is not a beverage or food, for example, if it is a detergent, it is possible to record the usage method and notes. Therefore, when purchasing the container 6, the user can know the product information with a reader provided at the store or a reader such as a mobile phone.

In the present embodiment, since the communication with the IC tag 5 is possible even after the composite cap 1 is opened, it is possible to notify information before opening and new contents after opening. For example, when a lottery is attached to a product, it is necessary to prevent it from being detected at a store or the like before purchasing the product.
Therefore, it is necessary to inform the user of the winning ticket after opening the cap after purchasing the product. Such cap hit information is recorded so that it is not known to the user before opening. Then, when the cutting circuit 36 of the IC tag 5 is cut, new hit information may be read from the IC tag 5.

When the user opens the composite cap, first, the push plate 9 of the overcap 2 is pushed from the unopened state of FIG. The push plate 9 is broken along the breaking line. Since the cutter 11 is provided on the bottom surface of the push plate 9, the cutter 11 breaks through the film substrate 33 as shown in FIG. Since the lead wire 37 of the cutting circuit 36 is disposed immediately below the cutter 11, the lead wire 37 is cut. A concave groove 28 is formed in the top plate 26 of the intermediate member 4, and the cutter 11 can bite into the concave groove 28 to easily cut the lead wire 37. In order to make it easier to cut, the film base material 33 may be cut in such a way that it is positioned on both the left and right sides of the portion (position) where the lead wire 37 is cut.
In order to protect the IC chip 34, the height of the cutter 11 is made larger than the depth of the concave groove 28, and the IC tag 5 remains between the push plate 9 and the top plate 26 even after the push plate 9 is broken. A thicker gap is formed.

In the present embodiment, since the position of the cutter 11 is positioned at the center of the overcap 2 and the position of the lead wire 37 is also positioned immediately below the center of the overcap 2, no alignment is required, and the overcap 2 Even the rotation angle of. The lead wire 37 can be cut.
In this way, a part of the cutting circuit 36 is disconnected, causing an electrical change (such as a voltage change due to a change in resistance) in the cutting circuit 36. This electrical change erases (or changes) new recording information built in the IC chip, for example, unopened information on the cap, and the reader then receives the opened information.

The user can confirm the date of manufacture and the expiration date of the product at the time of purchasing the container 6 or after purchase with a reading device such as a mobile phone. Further, information that the composite cap 1 is still unopened can be confirmed, and mischief such as exchange of contents after opening is recognized and prevented.
In addition, the user can know the winning lottery and campaign information recorded on the IC tag with a margin after opening the composite cap.
Furthermore, after the composite cap 1 is discarded and collected, by recording the cap type and color-specific information during recycling, identification by an automatic device or the like, and automatic sorting for each type can be performed. .
Thus, conventionally, since the antenna was disconnected, the IC tag information could not be obtained from the IC chip after the cap was opened, but in this embodiment, the IC tag is also opened after the composite cap 1 is opened. Tag information can be obtained.

Next, a third embodiment of the present invention will be described.
In the present embodiment, the shape of the composite cap 1 is the same as that of the second embodiment, and the configuration of the IC tag 51 is different. Therefore, the composite cap 1 will be described with the same reference numerals as those in the first and second embodiments.
An IC tag 51 shown in FIG. 9 includes a thin resin film base 52 having a circular thickness, an IC chip 53 having a recording medium, and an information transmission / reception antenna 54 connected to the IC chip 53. Therefore, the present embodiment does not include a cutting circuit for detecting opening that is pulled out from the IC chip 53.
In the present embodiment, a cutting lead wire 55 is provided between the antenna 56 and the IC chip 53 as the cutting circuit 54.
As shown in A of FIG. 8, the lead wire 55 is cut by the cutter 11 formed on the bottom surface of the push plate 9 described above, so that the lead wire 55 passes under the cutter 11 or by the cutter 11. It is important to arrange at the position to be cut. The cutter 11 needs to be disposed immediately above any part of the lead wire 55.

When the composite cap 1 is opened, the push plate 9 of the overcap 2 is pushed from the unopened state of FIG. The push plate 9 is broken along the breaking line. Since the cutter 11 is provided on the bottom surface of the push plate 9, the cutter 11 breaks through the film base material 33 when the push plate 9 is lowered downward. Since the lead wire 55 is disposed immediately below the cutter 11, the lead wire 55 is cut. A concave groove 28 is formed in the top plate 26 of the intermediate member 4, and the cutter 11 can bite into the concave groove 28 to easily cut the lead wire 55. In order to make it easier to cut, the film base 52 may be cut by positioning it on the left and right sides of the portion (position) where the lead wire 55 is cut.
When the lead wire 55 is cut, the connection between the IC chip 53 and the antenna 56 is cut, and the IC tag 51 becomes incapable of transmission / reception with the reading device. The seller, user, and the like can recognize that the composite cap 1 has been opened because the transmission / reception is disabled.

The present invention has been described in detail based on the embodiments with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments, and other modifications can be made without departing from the scope of the present invention. Or it can be changed.
For example, in the above embodiment, the intermediate member 4 inserts the peripheral wall 27 into the gap 43 and fixes the overcap 2 and the inner cap 3, but the intermediate member 4 moves the overcap 2 and the inner cap 3 in the rotation direction. For example, vertical grooves are formed on the inner peripheral surface of the overcap 2, vertical grooves are formed on the outer peripheral surface of the inner cap 2, and those grooves are formed on the outer peripheral surface of the peripheral wall 27 of the intermediate member 4. The overcap 2 and the inner cap 3 may be fixed by forming corresponding longitudinal grooves and fitting the longitudinal grooves together.
In the above embodiment, one cutter is used, but a plurality of cutters may be provided. For example, in 1st Embodiment, you may cut | disconnect two places of an antenna using two cutters. More certainty about the antenna disconnection.
