  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each embodiment, a case where the opening detection sheet and the opening detection device of the present invention are applied to detection of opening of a blister pack for tablets will be described as an example.

(Embodiment 1)
FIG. 1 is a diagram showing a configuration example of a blister pack for tablets. A blister package 1 shown in FIG. 1 includes a plastic storage sheet 2 and a cover sheet 3 having an aluminum foil as a base material. In each of the plurality of recesses 2a formed in the storage sheet 2, one tablet (or one dose) is placed.

  The entire surface of the storage sheet 2 is covered with a cover sheet 3 having the same size as the storage sheet 2, and a storage portion 5 for the tablet 4 is formed by a combination of the recesses 2 a and the cover sheet 3. When any one of the recesses 2a in which the tablets 4 are enclosed is crushed, the portion of the cover sheet 3 that has covered the recesses 2a is pierced by the tablets 4 in the recesses 2a, whereby the container 5 is The tablet 4 is taken out after being opened. That is, in the present embodiment, each storage unit 5 is a target (target unit) for opening detection.

  In the example of FIG. 1, the accommodating portions 5 are formed in an arrangement of seven stages in the longitudinal direction (longitudinal direction) of the accommodating sheet 2 and two rows in the lateral direction (short direction) of the accommodating sheet 2. In other words, in the vertical direction, the seven accommodating portions 5 are spaced apart from each other, and in the lateral direction, the two accommodating portions 5 are spaced apart from each other. However, this arrangement can be implemented with appropriate changes.

  FIG. 2 is a diagram showing an example of the configuration of the unsealing detection sheet according to the present embodiment, which is suitable for use in unsealing detection of the blister package 1 shown in FIG.

  The unsealing detection sheet 10 includes a sheet main body 11 made of, for example, a PET (polyethylene terephthalate) sheet, and a conductor portion 12 formed on the sheet main body 11.

  The sheet main body 11 is formed to have substantially the same size as the accommodation sheet 2, and is used by covering the cover sheet 3 and sticking on the cover sheet 3. The thickness is 0.6 mm, for example.

  On the main surface of the sheet main body 11 (the side opposite to the surface attached to the cover sheet 3), a conducting wire portion 12 is formed. The conducting wire portion 12 is formed by, for example, etching the aluminum foil (or copper foil) so as to have a wiring pattern corresponding to the arrangement of the accommodating portions 5 in seven stages and two rows.

  As will be described later, ADCs 85, 86, 87, and 88 (see FIG. 8) are used in the present embodiment, but in the ADCs 85 to 88, the influence of wiring resistance components is large. Therefore, in the present embodiment, the conductive wire portion 12 on the PET sheet does not use a material having a relatively large resistance value such as carbon particles or silver paste, and aluminum or the resistance value can be made substantially zero. It is preferable to use copper or the like. The aluminum pattern or copper pattern is also advantageous in that it is more resistant to bending or friction than carbon printing or silver paste printing.

  The conducting wire portion 12 is formed with common lines 21, 22, and 23 formed in the center portion in the width direction of the sheet body 11 so as to extend from the base end portion 11a (the hatched region in FIG. 2) of the sheet body 11 in the vertical direction. including. In addition, the conductive wire portion 12 is common to the conductive wires 31, 32, 33, 34, 35, 36 connected to the common wire 21 and the conductive wires 41, 42, 43, 44, 45, 46 connected to the common wire 22. Conductive wires 51 and 52 connected to the wire 23 are further included.

  The conducting wires 31 to 36 are respectively associated with the six accommodating portions 5 in the second to seventh stages from the upper right side that are spaced apart in the vertical direction. Each of the conducting wires 31 to 36 branches from the common wire 21 and extends in the lateral (right) direction so as to pass through the position of the corresponding accommodating portion 5 (passing conducting wires 31a, 32a, 33a, 34a, 35a, 36a). Rotate the right outer periphery of the seat body 11 and reach the base end 11a. The conducting wires 41 to 46 are respectively associated with the six accommodating portions 5 in the second to seventh stages from the upper left side that are spaced apart in the vertical direction. The conducting wires 41 to 46 branch from the common wire 22 and extend in the lateral (left) direction so as to pass through the positions of the corresponding accommodating portions 5 (passing conducting wires 41a, 42a, 43a, 44a, 45a, 46a). Rotate the left outer periphery of the seat body 11 and reach the base end 11a. The conducting wires 51 and 52 are respectively associated with the uppermost accommodating portions 5 on the left and right sides that are spaced apart in the horizontal direction. Therefore, each of the conducting wires 51 and 52 branches from the common wire 23 so as to pass through the position of the corresponding accommodating portion 5 and extends in the lateral (right and left) directions (passing conducting wires 51a and 52a), respectively, and the seat body 11 around the left and right outer peripheral parts to reach the base end part 11a.

  When any of the storage portions 5 is opened, the portion of the sheet main body 11 covering the storage portion 5 is also pierced by the tablet 4. Since conducting wire 31-36, 41-46, 51, 52 each passes through the position of the corresponding accommodating part 5, it is in the opened accommodating part 5 among conducting wires 31-36, 41-46, 51, 52. Corresponding ones are disconnected when the sheet body 11 is torn along with the opening of the accommodating portion 5.

  In the sheet main body 11, a slit 61 adapted to the shape of the tablet 4 or the accommodating part 5 is provided at the position of each accommodating part 5, more specifically, in the vicinity of each passing conducting wire 31 a to 36 a, 41 a to 46 a, 51 a, 52 a, 62 and 63 are formed. The slits 61, 62, 63 are formed on both sides of the neighboring passing conductors 31a-36a, 41a-46a, 51a, 52a. Therefore, when any of the accommodating portions 5 is opened, it can be ensured that the portion of the sheet main body 11 that has covered the accommodating portion 5 is torn, thereby breaking the wire at the corresponding position, And taking out of the tablet 4 accommodated in the accommodating part 5 can also be made easy.

  When any of the conducting wires is disconnected, it is preferable that the portion of the passing conducting wire is disconnected, and it is not preferable that the conducting wire portion along the outer peripheral portion of the sheet body 11 is disconnected. Therefore, in each conducting wire 31-36, 41-46, 51, 52, each passing conducting wire 31a-36a, 41a-46a, 51a, 52a is diagonally wired, and the length is extended, thereby the sheet body 11 The distance between the portion along the outer peripheral portion and the position of the corresponding accommodating portion 5 is increased.

  By the way, the common lines 21, 22, and 23 and the conducting wires 31 to 36, 41 to 46, 51, and 52 are electrically connected to a circuit board (not shown) through the connection part 12a disposed on the base end part 11a. Is possible. This circuit board can be integrated with the unsealing detection sheet 10 by adhesion (for example, ACF (anisotropic conductive film) connection) to the base end portion 11a.

  Therefore, a plurality of resistors are mounted on the circuit board bonded to the base end portion 11a, and these resistors are respectively connected to the conductive wires 31 to 36, 41 to 46, 51 and 52 through the terminals of the connecting portion 12a. Can be connected. In this case, since it is not necessary to mount a resistor on the sheet main body 11, the wiring pattern of the conductor portion 12 can be simplified.

  FIG. 3 is a diagram illustrating an example of a connection relationship between the lead wire and the resistance of the unsealing detection sheet.

  As shown in FIG. 3, the resistors R <b> 31 to R <b> 36 can be connected in parallel to each other by the conducting wires 31 to 36 connected to the common line 21. Similarly, the resistors R41 to R46 can be connected in parallel to each other by the conducting wires 41 to 46 connected to the common line 22. Further, the resistors R51 and R52 can be connected in parallel to each other by the conducting wires 51 and 52 connected to the common line 23. In this way, three parallel circuit portions are formed.

  Note that the number of parallel circuit portions formed in the unsealing detection sheet 10 may be one, two, or four or more. In addition, the number of resistors connected in parallel in one parallel circuit unit (the number of parallel connection resistors) may be any number as long as it is two or more, but as many as possible within a range in which the detection accuracy of opening can be maintained at a certain level or more. It is preferable that

In the circuit in which the resistors R31 to R36 are connected in parallel to each other, if any of the conducting wires 31 to 36 is disconnected, the number of parallel connection resistors is reduced. At this time, a change occurs in the combined resistance value of the resistors R31 to R36, and a change occurs in the voltage V1 _OUT generated by the combined resistor of the resistors R31 to R36 and the voltage dividing resistor DR30. The same applies to the voltage V2 _OUT generated by the combined resistance of the resistors R41 to R46 and the voltage dividing resistor DR40, and the voltage V3 _OUT generated by the combined resistance of the resistors R51 and R52 and the voltage dividing resistor DR50.

  In the present embodiment, opening detection can be performed using voltage changes in these circuits, which will be described later.

  Note that fixed resistors can be used for the resistors R31 to R36, R41 to R46, R51, and R52. These resistance values are preferably equal to each other.

  FIG. 4 is a diagram illustrating a first modification of the configuration of the unsealing detection sheet 10. 4, the same or corresponding components as those shown in FIG. 2 are given the same reference numerals.

  Since the lead wire part 12 in this example has a wiring pattern corresponding to the arrangement of five stages and two rows, it is suitable for use in detecting the opening of blister packaging in which the tablet storage parts are arranged in five stages and two rows. Yes. Moreover, in this example, the passing conductors 31a to 35a and 41a to 45a are extended in the vertical direction with respect to the common lines 21 and 22 extending in the vertical direction, so that the conducting wire portion 12 has a simple form. The slits 61 and 62 are formed in a circular shape. When the tablet is circular, the slits 61 and 62 are preferably circular as described above.

  FIG. 5 is a diagram illustrating a second modification of the configuration of the unsealing detection sheet 10. In FIG. 5, the same or corresponding components as those shown in FIG. 2 are given the same reference numerals.

  In this example, resistors (fixed resistors) 31b to 35b and 41b to 45b are disposed on the passing conductors 31a to 35a and 41a to 45a. The resistors 31b to 35b and 41b to 45b are mounted by ACF. Therefore, a circuit in which a plurality of resistors are connected in parallel to each other can be formed on the sheet body 11, thereby eliminating the need to dispose the resistors on the circuit board used in combination with the unsealing detection sheet 10. Can do. Furthermore, since the wiring pattern can be reduced, the number of terminals can be reduced in the connection portion 12a.

  Furthermore, regarding the forms of the respective passing conductors 31a to 36a, 41a to 46a, 51a and 52a and the corresponding slits 61, 62 and 63, the ease of breaking of the passing conductors 31a to 36a, 41a to 46a, 51a and 52a is taken into consideration. Various forms can be adopted. FIG. 6 shows some examples.

  FIG. 7 is a block diagram showing a configuration of the unsealing detection apparatus according to the present embodiment.

  The unsealing detection device 70 includes an unsealing detection processing unit 71, a power supply unit 72, a data storage unit 73, a wireless transmission / reception unit 74, an antenna 75, and a parallel circuit unit 76.

  The unsealing detection processing unit 71 has a configuration including, for example, ADCs 85 to 88 and a CPU (Central Processing Unit) 89 (see FIG. 8), and performs unsealing detection using a voltage change in the parallel circuit unit 76.

  The power supply unit 72 has a configuration including, for example, a coin battery and a DC-DC converter, and supplies power to each unit in the apparatus.

  The data storage unit 73 has a configuration including, for example, a nonvolatile memory, and intermittently (for example, every 10 minutes) stores the result of opening detection in the opening detection processing unit 71 as data. That is, the data storage unit 73 is a necessary component when the unsealing detection device 70 is used as a data logger or a time logger for storing the unsealing detection result.

  The wireless transmission / reception unit 74 includes a transceiver that performs wireless transmission / reception using Bluetooth (registered trademark), for example, and wirelessly transmits data stored in the data storage unit 73 via the antenna 75.

  The parallel circuit unit 76 includes three parallel circuit units. The first parallel circuit section 76a (see FIG. 8) forms resistors S31 by connecting resistors R31 to R36 in parallel by conducting wires 31 to 36 connected to the common line 21. The second parallel circuit portion 76 b (see FIG. 8) forms the combined resistance CR 40 by connecting the resistors R 41 to R 46 in parallel by the conductive wires 41 to 46 connected to the common line 22. The third parallel circuit portion 76c (see FIG. 8) forms resistors S50 by connecting the resistors R51 and R52 in parallel by the conducting wires 51 and 52 connected to the common line 23.

  The common lines 21-23 and the conductive lines 31-36, 41-46, 51, 52 are all provided in the unsealing detection sheet 10, and the resistors R31-R36, R41-R46, R51, R52 are all It can be mounted on a circuit board used together with the unsealing detection sheet 10. Therefore, the opening detection device 70 can detect the opening of the blister package 1 using the opening detection sheet 10.

  FIG. 8 is a diagram schematically illustrating an example of a circuit configuration in the first to third parallel circuit units 76 a to 76 c and the unsealing detection processing unit 71.

A power supply voltage is sequentially applied from the power supply unit 72 to the first to third parallel circuit units 76a to 76c through the common lines 21 to 23, respectively. Currents flowing through the common lines 21 to 23 are converted into voltage signals by the voltage dividing resistors DR30 to DR50. These voltage signals are input to the ADCs 86 to 88, and the respective voltage levels V _{ADC — 01} , V _{ADC — 02} , and V _{ADC — 03} are detected by the ADCs ₈₆ to 88.

If any one or more accommodating parts 5 located in the area | region of the 1st parallel circuit part 76a are opened, the parallel connection resistance number in the synthetic | combination resistance CR30 will decrease by the disconnection which arises in the conducting wires 31-36. As a result, the voltage level V _{ADC — 01} of the voltage signal generated in the voltage _dividing resistor DR30 is lowered. In other words, the voltage level V _{ADC — 01} of the voltage signal from the first parallel circuit unit 76 a changes according to the number of the accommodating units 5 opened.

Here, the power supply voltage from the power supply unit 72 is 2.6 [V], the resistance value of the voltage dividing resistor DR30 is 1.6 [kΩ], the tolerance is ± 1 [%], and each resistance R31- The resistance value of R36 is 10 [kΩ], and the tolerance is ± 5 [%]. Under this condition, the voltage level V _{ADC — 01} is 1.235 to 1.313 [V] when the number of parallel connection resistors is six. Further, as the number of parallel connection resistors decreases by one, the voltage level V _{ADC — 01} is 1.118 to 1.195 [V], 0.978 to 1.053 [V], 0.810 to 0.879 [V. ], 0.603 to 0.660 [V], 0.341 to 0.378 [V], and 0.000 [V].

Assuming that the resolution of the ADC 86 is 10 bits, the ADC 86 is _{approximately} 498 (six parallel connection resistors), approximately 450 (same as 5), _{approximately} 395 (same as 4), with respect to the above value of the voltage level V _{ADC — 01} . A value of around 329 (same 3), around 247 (same 2), around 143 (same 1) or about 0 (same 0) is output. Therefore, the CPU 89 can determine the number of parallel connection resistors of the first parallel circuit section 76 a based on the output value of the ADC 86, and thus can determine the number of the opened accommodating sections 5.

  In order to determine the number of opened storage parts 5 in the range of 0 to 6, it is necessary to set five determination threshold values in the CPU 89. It is assumed that the maximum value among the five determination thresholds is set to 475, for example. In this case, when the output value of the ADC 86 is 475 or more, the number of parallel connection resistors of the first parallel circuit section 76a can be determined to be 6, in other words, the number of disconnections can be determined to be 0. Therefore, it can be determined that the number of opened accommodating portions 5 is zero. For example, when the other determination thresholds are set to 425, 365, 197, and 72, the number of the opened storage units 5 can be accurately determined even in the range of 1 to 6.

  From the above description of the first parallel circuit portion 76a, it is clear that the opening of the housing portion 5 can be determined similarly in the second and third parallel circuit portions 76b and 76c.

The power supply voltage may fluctuate, and the fluctuation may affect the values of the voltage levels V _{ADC — 01} , V _{ADC — 02} , and V _{ADC — 03} . Therefore, when it is determined that the housing unit 5 is opened based on the voltage level V _{ADC — 01} of the voltage signal from the first parallel circuit unit 76 a, the voltage level V _{ADC —} 00 of the power supply voltage of the first parallel circuit unit 76 a is digitally _converted by the ADC 85. It is preferable to _convert the value into a value and correct the value of the voltage level V _{ADC — 01} based on the value. The same _{applies to} the values of the voltage levels V _{ADC — 02} and V _{ADC — 03} . The multiplexer MUX selects the input to the ADC 85 so that the power supply voltages of the first to third parallel circuit units 76a to 76c can be taken into account when correcting the voltage levels V _{ADC — 01} , V _{ADC — 02} , and V _{ADC — 03} , respectively. It is preferable to switch sequentially by a signal.

In addition, there is a method that is not affected by fluctuations in power supply voltage as compared with the above method. For example, the power supply voltage and the divided voltage are measured, and the combined resistance values of the combined resistors CR30 to CR50 are measured by these values and the divided resistors DR30 to DR50 connected to the GND. Based on these values, This is a method of determining the number of the accommodating units 5 opened. More specifically, the combined resistance value of the combined resistor CR30 can be calculated by the following equation. In the _{formulas, R CR30} is a synthetic resistance value of the combined resistor _{CR30, R DR30} is the resistance of the voltage dividing resistors DR30.
_RCR30 = (V _{ADC — 00} −V _{ADC — 01} ) × R _DR30 / V _{ADC — 01}

The combined resistance values R _CR40 and R _CR50 of the combined resistors CR40 and CR50 can be calculated by the same equations as described above using the corresponding resistance values R _DR40 and R _DR50 of the _voltage dividing resistors DR40 and DR50, respectively.

  Hereinafter, a usage scenario as a tablet administration time management application will be described.

[Step 1]
At the pharmacy, the pharmacist gives the patient the blister pack 1 (with the opening detection device 70) in which the prescription drug (tablet 4) is enclosed. At this time, pairing between the unsealing detection device 70 and the terminal device in which the electronic medical record is managed is performed. In this pairing, the data of the name and the number of the tablets 4 are acquired by wireless communication from the opening detection device 70 attached to the blister pack 1, and the acquired information is linked with the electronic medical record of the patient and the acquisition is performed. Time is recorded.

[Step 2]
The patient takes the tablet 4 according to the prescribed taking time.

[Step 3]
The unsealing detection device 70 is activated at a constant cycle (for example, every 10 minutes), and causes the unsealing detection processing unit 71 to perform the above-described determination. The opening detection processing unit 71 detects the number of tablets 4 to be taken, and records the number of times taken and the detection time in the data storage unit 73 when there is a difference from the previously detected number of doses. When this recording is completed, the unsealing detection device 70 is in a low current consumption state until the next startup.

[Step 4]
The patient brings the empty blister pack 1 (with the opening detection device 70) to the pharmacy at the next hospital visit.

[Step 5]
The terminal device of the pharmacy acquires the number of doses and detection time data stored in the data storage unit 73 of the opening detection device 70 by wireless communication.

  In the pharmacy, by acquiring this data, it is possible to confirm whether the prescription drug is being taken correctly and whether the prescription drug has been forgotten. Furthermore, when a criminal problem due to drug use occurs, the acquired data can be used as evidence of a history of taking.

  As described above, according to the present embodiment, in the opening detection sheet 10, the conductive wires 31 to 36, 41 to 46, 51, 52 are formed so as to be disconnected along with the opening of the corresponding accommodating portion 5. Has been. Conductive wires 31-36, 41-46, 51, 52 are wired to connect resistors R31-R36, R41-R46, R51, R52 in parallel with each other. Therefore, the number of parallel connection resistors can be changed along with the disconnection, and the opening detection of the housing portion 5 can be performed based on the voltage fluctuation according to the number.

  In the present embodiment, resistors R31 to R36 are connected in parallel to each other by conducting wires 31 to 36, resistors R41 to R46 are connected to each other in parallel by conducting wires 41 to 46, and resistors R51 and R52 are connected to each other in parallel by conducting wires 51 and 52. A wiring pattern to be connected to is adopted. Thereby, in the 1st parallel circuit part 76a containing the conducting wires 31-36 and resistance R31-R36, the number of wiring connected to the opening detection process part 71 for the opening detection of the six accommodating parts 5 is only one. It can be. Also in the second parallel circuit portion 76b including the conductive wires 41 to 46 and the resistors R41 to R46, the number of wirings connected to the unsealing detection processing unit 71 for detecting unsealing of the six accommodating portions 5 is limited to one. be able to. In the third parallel circuit portion 76c including the conducting wires 51 and 52 and the resistors R51 and R52, the number of wirings connected to the unsealing detection processing unit 71 for detecting unsealing of the two housing portions 5 is only one. be able to. As described above, the number of wirings connected to the unsealing detection processing unit 71 can be greatly reduced as compared with the number of the accommodating units 5 that are targets of unsealing detection.

  Moreover, the conducting wire part 12 including the conducting wires 31 to 36, 41 to 46, 51, 52 further includes common lines 21 to 23 connected to the conducting wires 31 to 36, 41 to 46, 51, 52. ˜23 extend in the longitudinal direction of the sheet main body 11 from the base end portion 11 a of the sheet main body 11. The conducting wires 31 to 36, 41 to 46, 51, 52 pass through the conducting wires 31 a to 36 a, 41 a extending from the common wires 21 to 23 in the lateral direction of the sheet main body 11 so as to pass through the positions of the corresponding accommodating portions 5. -46a, 51a, 52a. The passage conducting wires 31a to 36a, 41a to 46a, 51a and 52a are separated in the longitudinal direction of the sheet main body 11 in correspondence with the accommodation portion 5 being separated in the longitudinal direction of the accommodation sheet 2 in the blister packaging 1. And wired. That is, the conductive wire portion 12 includes a common wire 21 extending in the vertical direction and conductive wires 31 to 36 including passing conductive wires 31a to 36a extending in the horizontal direction from the common line 21 for each step separated in the vertical direction. It is formed to be a ladder-like wiring pattern by combination. Moreover, the conducting wire portion 12 includes a common wire 22 extending in the vertical direction, and conducting wires 41 to 46 including passage conducting wires 41a to 46a extending in the horizontal direction from the common line 22 for each step separated in the vertical direction. It is formed to be a ladder-like wiring pattern by combination.

  Therefore, for example, even if the unsealing detection sheet 10 is cut at a position between the second-stage passing conductors 31a and 41a and the third-stage passing conductors 32a and 42a from the top, the third to seventh stages from the top The closed state of the circuit including the through wires 32a to 36a and 42a to 46a can be maintained. Furthermore, even if the unsealing detection sheet 10 is cut at a position between the third-stage passing conductors 32a, 42a and the fourth-stage passing conductors 33a, 43a from the top, the fourth to seventh stages from the top are passed. The closed state of the circuit including the conducting wires 33a to 36a and 43a to 46a can be maintained. Therefore, when opening the container 5 in order from the top, even if the part of the opening detection sheet 10 that has become unnecessary from the top is cut off, the remaining part of the opening detection sheet 10 is used to store the lower part. The detection of opening of the unit 5 can be continued. Thereby, the pharmacist can adjust the length of the opening detection sheet | seat 10 according to the length of the blister package 1 according to the number of tablets handed over to a patient at the time of prescription. Moreover, the patient can isolate | separate the unnecessary part corresponding to the accommodating part 5 already opened. Therefore, the patient can carry the unsealing detection sheet 10 with the minimum necessary length.

  It should be noted that perforations may be formed between the stages in the sheet body 11 so as to facilitate cutting between the stages.

  In addition, the opening detection device 70 can determine whether the container 5 has been opened by processing the opening detection sheet 10 and the voltage signals from the first to third parallel circuit portions 76a to 76c. Part 71. More specifically, the unsealing detection processing unit 71 includes ADCs 86 to 88 that perform analog-digital conversion on the voltage signals from the first to third parallel circuit units 76a to 76c, and ADCs 86 to 88 that vary due to disconnection. Based on the output value, the opening of the storage unit 5 is determined. Therefore, according to this Embodiment, the unsealing detection apparatus 70 provided with the unsealing detection sheet 10 can be provided.

Further, in the first to third parallel circuit portions 76a to 76c, if there is a defect in the connection of the resistors R31 to R36, R41 to R46, R51, and R52 at the time of manufacture, the influence is affected by the voltage levels V _{ADC — 01} , V _{ADC — 02} , _Appears at V _{ADC — 03} . Therefore, when the opening detection sheet 10 or the opening detection device 70 is manufactured, the first to third parallel circuit units 76a to 76c detect the voltage levels V _{ADC — 01} , V _{ADC — 02} , and V _{ADC — 03} , respectively. It is possible to determine a failure in the connection of R36, R41 to R46, R51, and R52.

(Embodiment 2)
When the contents of the recesses of the unsealing detection sheet are thin or small, in the unsealing detection sheet having the configuration illustrated in FIG. There is a possibility of slipping through. Therefore, as a second embodiment of the present invention, a configuration of an unsealing detection sheet that is more suitable for a thin container or a small container will be described.

  In the present embodiment, the shape of the outer periphery (hereinafter referred to as “the outer periphery of the storage portion”) of the storage portion 5 (target portion; see FIG. It is assumed that it is almost the same as the external shape.

  In addition, in the configuration of the unsealing detection sheet according to the present embodiment, portions other than the accommodating portion 5 and the vicinity thereof are the same as those of the unsealing detection sheet according to Embodiment 1.

  Further, the unsealing detection sheet according to the present embodiment can be used as a part of the unsealing detection apparatus according to the first embodiment shown in FIGS. 7 and 8, similarly to the unsealing detection sheet according to the first embodiment. However, the unsealing detection sheet according to the present embodiment is also suitable for an unsealing detection device that uses GPIO (General Purpose Input / Output) instead of an AD converter to detect the number of extracted items. It is. In this case, a material having a relatively large resistance value, such as carbon particles or silver paste, can be used for the conductor portion.

  9-12 is a figure which shows the 1st-4th example of a structure of the unseal | open detection sheet | seat which concerns on this Embodiment.

  As shown in FIGS. 9-12, the slit 6a has the shape along the accommodating part outer periphery 5a. However, the slit 6a is provided avoiding a position P (hereinafter referred to as a “conductor crossing position”) where the housing outer periphery 5a and the conductor 12b intersect. Thereby, it can prevent that the conducting wire 12b will be cut | disconnected by the tear of the slit 6a in the step in which the accommodating part 5 is not opened.

  The conducting wire 12b is formed so as to intersect with one housing portion outer periphery 5a at four locations. The length D between adjacent conductor crossing positions is shorter than the width of the contents. In addition, the conducting wire 12 b projects near the center of the housing portion 5.

  In the example shown in FIGS. 9 and 10, all the four conductor crossing positions P are separated from each other with the slit 6a interposed therebetween.

  In the example shown in FIG. 11 and FIG. 12, two conductor intersection positions P among the four conductor intersection positions P are arranged close to each other on the outer periphery 5a of the accommodating portion and separated from the other intersection positions P. Yes.

  The cover sheet 3 is difficult to tear from the beginning. Therefore, the opening detection sheet having the configuration shown in FIGS. 9 to 12 can reduce the possibility that the cover sheet 3 starts to tear from the inner region of the housing outer periphery 5a, and the cover sheet 3 starts to tear from the slit 6a. The possibility can be increased.

  In addition, the one where the maximum value of the said length D is smaller can maintain a required opening detection performance more reliably with respect to a thin accommodation thing or a small accommodation thing. Therefore, it is desirable that the four conductor crossing positions P are arranged at regular intervals on the outer periphery 5a of the accommodating portion. That is, for example, as in the example shown in FIG. 10, when the accommodating portion outer periphery 5 a is circular, the four conductor crossing positions P are arranged at an interval obtained by dividing the length of the accommodating portion outer periphery 5 a into four equal parts. Is desirable. Similarly, in the example shown in FIG. 12, it is desirable to arrange the three conductor crossing positions P at intervals obtained by dividing the length of the housing portion outer periphery 5 a into three equal parts.

  The region where the conductor crossing position P is arranged close to each other (shown as region A in FIGS. 11 and 12) is less likely to be broken because the sheet body 11 has fewer slits 6a. That is, there is a restriction on the direction in which the cover sheet 3 is torn. Accordingly, with the configuration shown in FIGS. 11 and 12, the unsealing detection sheet guides the direction in which the cover sheet 3 is torn to the side opposite to the region A (upper side in the figure), and is more easily torn at the opposite side portion. can do.

  A situation can be considered in which the direction of the finger to be pushed with respect to the opening detection sheet is determined to some extent. For example, the opening detection sheet may be guided by the shape or information display of the opening detection sheet.

  In such a case, if the four conductor crossing positions P are arranged so that the easily torn side comes in the direction in which the fingertip at the time of opening is directed, the effect of the guidance is increased. Therefore, when the direction of the finger to be pushed is fixed, the configuration shown in FIGS. 11 and 12 can maintain the necessary opening detection performance more reliably than the configurations shown in FIGS. Is possible.

  On the other hand, the configuration shown in FIGS. 9 and 10 can make the maximum value of the length D smaller than the configurations shown in FIGS. 11 and 12. Therefore, when the direction of the finger to be pushed out is not fixed, the configuration shown in FIGS. 9 and 10 can more reliably maintain the necessary opening detection performance than the configurations shown in FIGS. Is possible.

  As described above, the unsealing detection sheet according to the present embodiment is wired so that the conducting wire intersects the outer periphery of the corresponding target portion at at least four intersection positions. In the opening detection sheet according to the present embodiment, each slit 6a forms a slit group arranged along the outer periphery 5a (outer periphery of the target portion) and sandwiching the intersection position. Thereby, the opening detection sheet | seat which concerns on this Embodiment can maintain required opening detection performance more reliably.

  In addition, it is also possible to comprise the conducting wire 12b so that it may cross | intersect the accommodating part outer periphery 5a in six or more places. In this case, it is possible to further reduce the possibility that the conductor 12b is not cut when the contents are taken out. However, when the crossing portions of the conducting wires 12b are increased, when the force is pushed out with the same force, the force is dispersed, so that the cutting force per one intersection is lowered, and it is difficult to open the housing portion 5. Therefore, it is desirable that the optimal value is selected for the number of locations where the conducting wire 12b intersects the accommodating portion outer periphery 5a in consideration of the trade-off relationship.

  Moreover, after the conducting wire is once cut, a phenomenon may occur in which the cut portion comes into contact and is connected again (hereinafter referred to as “reconnection phenomenon”). If such a reconnection phenomenon occurs simultaneously at all the cut points of the same conducting wire, it causes false detection. On the other hand, the more the number of cut points of the conducting wire, the lower the possibility that the reconnection phenomenon will occur simultaneously at all the cut points.

  As compared with the unsealing detection sheet according to the first embodiment, the unsealing detection sheet according to the present embodiment is more likely to be cut at more points. Therefore, the opening detection sheet according to the present embodiment can reduce the possibility of erroneous detection due to the reconnection phenomenon.

(Embodiment 3)
Embodiment 3 of the present invention describes the configuration of an unsealing detection sheet that prevents the occurrence of the reconnection phenomenon itself.

  Note that, in the configuration of the unsealing detection sheet according to the present embodiment, the portions other than the housing portion 5 and the vicinity thereof are the same as the configuration of the unsealing detection sheet according to Embodiment 1.

  Further, the unsealing detection sheet according to the present embodiment can be used as a part of the unsealing detection apparatus according to the first embodiment shown in FIGS. 7 and 8, similarly to the unsealing detection sheet according to the first embodiment. However, the unsealing detection sheet according to the present embodiment is also suitable for an unsealing detection apparatus that uses GPIO to detect the number of extracted items to be extracted. In this case, a material having a relatively large resistance value, such as carbon particles or silver paste, can be used for the conductor portion.

  13 to 16 are diagrams showing first to fourth examples of the configuration of the unsealing detection sheet according to the present embodiment, and correspond to FIGS. 9 to 12 of the second embodiment. The configuration shown in FIGS. 13 to 16 is different from the configuration shown in FIGS. 9 to 12 only in the width of the slit 6a.

  As shown in FIGS. 13 to 16, the slit 6 a of the opening detection sheet according to the present embodiment is wider than the slit 6 a shown in FIGS. 9 to 12. More specifically, the slit 6a has a relatively large width on the inner side and the outer side of the accommodating portion outer periphery 5a.

  17 and 18 are diagrams showing an example of a cross section of the unsealing detection sheet according to the present embodiment, and correspond to FIG. 1B of the first embodiment. FIG. 17 shows a cross section of a portion where the accommodating portion 5 is not arranged. FIG. 18 shows a cross section of a portion where the accommodating portion 5 is arranged. Moreover, in FIG. 18, the part corresponding to the conductor crossing position P is shown on the left side of the accommodating part outer periphery 5a, and the part corresponding to the slit 6a in the accommodating part outer periphery 5a is shown on the right side.

  As shown in FIGS. 17 and 18, in the opening detection sheet, a cover sheet (sealing aluminum) is formed on the surface of the storage sheet (also referred to as a blister case) 2 that forms the storage portion 5 on the side where the stored items are pushed out. (Also referred to as a sheet) 3 is attached. The cover sheet 3 includes a sheet main body 11 provided with a conducting wire 12b on the surface, and a double-sided tape 13 (adhesive portion) for adhering the surface of the sheet main body 11 on which the conducting wire 12b is provided to the cover sheet 3. Composed. The double-sided tape 13 is obtained by, for example, applying an adhesive to a base material having insulation properties such as PET or paper.

  That is, the unsealing detection sheet has a configuration in which the accommodation sheet 2, the cover sheet 3, the double-sided tape 13, the conducting wire 12 b, and the sheet body 11 are laminated. In the region between the double-sided tape 13 and the sheet main body 11, an air layer 12 c may exist in a region where the conducting wire 12 b does not exist, but desirably, in the region where the conducting wire 12 b does not exist, the double-sided tape 13 and the sheet. The main body 11 is in close contact with each other.

  The slit 6a is provided in the sheet body 11, for example. That is, the slit 6 a is an opening provided in the sheet body 11.

  When the container is pushed out in the opening detection sheet having such a configuration, first, the cover sheet 3 and the cover sheet 3 are pushed out by the container and start to tear from the slit 6a (the cover sheet 3 and the double-sided tape 13). And if the slit 6a is torn, the area | region (the cover sheet 3, the double-sided tape 13, and the sheet | seat main body 11) inside the torn slit 6a among the cover sheets 3 will be extruded further outside. Then, the area | region between the torn slit 6a and the slit 6a, ie, conducting wire crossing position P (the cover sheet 3, the double-sided tape 13, the conducting wire 12b, and the sheet | seat main body 11) spreads.

  The ductility of the conducting wire 12b is lower than the ductility of the sheet body 11 due to the difference in material. Therefore, when the conductor crossing position P is extended, the conductor 12b is cut first, and the sheet body 11 is cut after being extended longer than the cut surface of the conductor 12b. When the width of the slit 6a is large, the region of the conductor crossing position P is relatively elongated. For this reason, the sheet body 11 is elongated and then cut. Such a portion of the sheet body 11 cut after being elongated is easy to wrap the cut portion of the conductive wire 12 b between the double-sided tape 13.

  That is, the unsealing detection sheet according to the present embodiment can wrap the cut portion of the conducting wire 12b between the sheet main body 11 and the double-sided tape 13 so as not to be exposed. Thereby, the opening detection sheet | seat which concerns on this Embodiment can make it difficult to generate | occur | produce a reconnection phenomenon.

  In addition, as the planar shape (hereinafter referred to as “cutting line shape”) of the cut portion of the cover sheet 3 is a random shape, the possibility that the outer side and the inner side of the cut portion are arranged in the original positional relationship is lower. Become. The possibility of the reconnection phenomenon, particularly the reconnection phenomenon occurring at a plurality of locations at the same time is extremely low.

  The cutting line shape of the cover sheet 3 becomes a random shape as the area of the slit 6a where the cover sheet 3 is attached to the storage sheet 2 is wider.

  In the opening sheet according to the present embodiment, as described above, the slit 6a protrudes outward from the housing portion outer periphery 5a. Therefore, the area of the slit 6a where the cover sheet 3 is affixed to the storage sheet 2 is wider than that of the second embodiment. Therefore, the unsealing detection sheet according to the present embodiment can make the cutting line shape of the cover sheet 3 a random shape, and can further reduce the reconnection phenomenon.

  As described above, in the unsealing detection sheet according to the present embodiment, the slit projects from the outer periphery of the housing portion to the outside of the outer periphery of the housing portion. Thereby, the opening detection sheet | seat which concerns on this Embodiment can make it difficult to generate | occur | produce the reconnection phenomenon of conducting wire.

  In addition, in the manufacturing process of the unsealing detection sheet, the storage sheet 2 to which the cover sheet 3 is attached and the cover sheet 3 may be manufactured separately. In this case, the cover sheet 3 is desirably manufactured in a state where a sheet-like member (release sheet) that can be easily peeled off from the double-sided tape 13 is attached to the surface of the double-sided tape 13. Thereby, the above-described high-accuracy opening detection sheet can be manufactured without considering the sanitary level required in the manufacture of the storage sheet 2, and the degree of freedom in the manufacturing process of the opening detection sheet can be improved.

  The cross-sectional configuration of the unsealing detection sheet is not limited to the configuration described with reference to FIGS. 17 and 18. For example, the unsealing detection sheet may also have a slit in the double-sided tape. Further, the unsealing detection sheet may have an area where the double-sided tape does not exist in an area other than the slit. However, it is preferable that the double-sided tape 3 is disposed so as to cover at least the conductive wire 12b in order to reliably avoid conduction between the cover sheet 3 made of aluminum foil and the conductive wire 12b. Further, the unsealing detection sheet may include a member other than the double-sided tape, such as a liquid adhesive, as a member for bringing the conductor and the PET sheet into close contact with the containing sheet.

  Here, the second embodiment is compared with the third embodiment. In the third embodiment, since how to tear the cover sheet becomes more random, the unsealing detection sheet according to the second embodiment has a better operational feeling at the time of extrusion depending on the type of contents. On the other hand, the unsealing detection sheet according to Embodiment 3 can more reliably prevent the reconnection phenomenon. Accordingly, it is desirable that the configuration of the unsealing detection sheet is selected in accordance with the type of the stored item and the required detection accuracy in consideration of the trade-off relationship.

  Note that the cross-sectional configuration of the unsealing detection sheet described with reference to FIGS. 17 and 18 can also be applied to the unsealing detection sheet according to Embodiment 1 and Embodiment 2.

(Embodiment 4)
Embodiment 4 of the present invention describes the configuration of an unsealing detection sheet in which the lead wire is more reliably cut after the unsealing detection sheet starts to break from the slit.

  Note that, in the configuration of the unsealing detection sheet according to the present embodiment, portions other than the shape of the slit are the same as those of the unsealing detection sheet according to Embodiments 1 to 3.

  19-22 is a figure which shows the 1st-4th example of a structure of the unseal | open detection sheet which concerns on this Embodiment.

  As shown in FIGS. 19-22, the slit 6a in this Embodiment has the split 6b in the vicinity of the conducting wire crossing position P among the edges. The split 6b extends toward the side where another slit 6a adjacent to the conductor crossing position P is located.

  In the example shown in FIG. 19, the split 6b is provided at the corner of the slit 6a. In the example shown in FIG. 20, the split 6b extends in a direction perpendicular to the conducting wire 12b. In the example shown in FIG. 21, a corner is formed at the end of the slit 6a, and the split 6b is provided at the corner in a direction perpendicular to the conducting wire 12b. In the example shown in FIG. 22, the split 6b is arranged obliquely between the slits 6a facing each other.

  By providing these splits 6b, the conducting wire 12b is easily cut. Therefore, the unsealing detection sheet having the slit shape shown in FIGS. 19 to 22 can more reliably cut the conductive wire when the stored item is pushed out.

  In particular, the configuration shown in FIG. 22 can guide the cutting of the conductor crossing position P so as to be split at an oblique angle with respect to the conductor 12b. If the conductor crossing position P is torn at an oblique angle with respect to the conductor 12b, the possibility of the reconnection phenomenon being further reduced. Therefore, the unsealing detection sheet having the shape of the slit shown in FIG. 22 not only ensures that the lead wire is cut more reliably when the contents are pushed out, but can further reduce the possibility of the reconnection phenomenon occurring. it can.

  In addition, when the slit 6a is formed by die-cutting the sheet main body 11, the split 6b can be easily formed by providing a part corresponding to the split 6b in the mold of the slit 6a, for example. it can.

  As described above, the unsealing detection sheet according to the present embodiment has a plurality of slits for each target portion in the sheet body, and the slits are split toward the side where other adjacent slits are located. Have. Thereby, the opening detection sheet | seat which concerns on this Embodiment can be made to cut | disconnect a conducting wire more reliably after an opening detection sheet | seat begins to tear from a slit.

The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
