[0020] An embodiment of the invention will be described with reference to the drawings. FIG. 1 is a diagram showing a medical needle 2. FIG. 2 is a diagram showing a needle hub 3. FIG. 3 is a diagram showing a needle cover 7. As shown in FIG. 1, the medical needle 2 includes a needle hub 3 and a needle cover 7. The needle hub 3 is a component to which the needle 5 is attached. The needle hub 3 functions as a base for the needle 5. The needle cover 7 is a component for covering the needle 5. The needle cover 7 is attached to the needle hub 3 when in use. A boundary line 9 in FIG. 1 indicates the boundary line between the needle hub 3 and the needle cover 7 on the outer circumferential surface of the medical needle 2.

[0021] FIG. 1 shows orthogonal X-axis and Y-axis. The X-axis is an axis that extends in a direction parallel to the needle 5. The needle base 3 is located in the positive direction of the X-axis on the needle cover opening detection label 1. The needle cover 7 is located in the negative direction of the X-axis on the needle cover opening detection label 1. The boundary line 9 is parallel to the Y-axis. The X-axis and Y-axis are also shown in other figures. The directions of the X-axis and Y-axis shown in other figures are the same as those in FIG. 1.

[0022] Figure 4 is an enlarged view of a medical needle 2. A needle cover opening detection label 1 is affixed to the medical needle 2. The needle cover opening detection label 1 is a label that allows the fact that the needle cover 7 has been removed from the hub 3 to be recognized from the outside, even if the needle cover 7 is removed from the hub 3 and then returned to the hub 3.

[0023] The needle cover opening detection label 1 includes a label body 10 and an adhesive layer. The adhesive layer is not shown. The label body 10 is the base material of the needle cover opening detection label 1. The material of the label body 10 may be a resin film, paper, or the like. An adhesive layer is disposed on one side of the label body 10. The label body 10 is attached to the medical needle 2 via the adhesive layer.

[0024] The needle cover opening detection label 1 is affixed to the medical needle 2, straddling the boundary line 9. The needle cover opening detection label 1 is affixed to the needle hub 3 and needle cover 7 by straddling the boundary line 9.

[0025] Since the needle cover opening detection label 1 is affixed to the needle hub 3 and the needle cover 7, the needle cover opening detection label 1 is torn when the needle cover 7 is removed from the needle hub 3. Even if the needle cover 7 is returned to the needle hub 3, the torn needle cover opening detection label 1 makes it easy to recognize from the outside that the needle cover 7 has been once removed from the needle hub 3.

[0026] The needle cover opening detection label 1 will be specifically described with reference to Fig. 5A. Fig. 5A is a diagram showing the label body 10 of the needle cover opening detection label 1. The label body 10 includes a needle hub portion 12 and a needle cover portion 14. The needle hub portion 12 is the portion of the label body 10 that is attached to the needle hub 3. The needle cover portion 14 is the portion of the label body 10 that is attached to the needle cover 7.

[0027] The needle hub portion 12 has an approximately rectangular shape. The needle cover portion 14 includes a first needle cover portion 15 and a second needle cover portion 16. The first needle cover portion 15 is a portion that extends continuously from the needle hub portion 12 in the negative direction of the X-axis. The first needle cover portion 15 has an approximately rectangular shape. The first needle cover portion 15 is preferably shaped like a rectangle, but the shape is not particularly limited.

[0028] 5A indicates the length in the Y-axis direction of the needle base portion 12. Length 61 in FIG. 5A indicates the length in the Y-axis direction of the first needle cover portion 15. Length 61 is approximately the same as length 60.

[0029] The second needle cover part 16 is a part that extends further in the negative direction of the X-axis from the first needle cover part 15. The shape of the second needle cover part 16 is approximately rectangular. The second needle cover part 16 is long in the direction of the Y-axis. A length 62 in FIG. 5A indicates the length of the second needle cover part 16 in the direction of the Y-axis. The length 62 is longer than the length 60.

[0030] The needle cover 7 may be made of a poorly adhesive material. An example of a poorly adhesive material is polypropylene. The needle cover opening detection label 1 of this embodiment includes a second needle cover portion 16 that is long in the Y-axis direction. Therefore, even if the needle cover 7 is made of a poorly adhesive material, the needle cover opening detection label 1 can be made difficult to peel off from the needle cover 7.

[0031] An inclined portion 18 is arranged in the negative direction of the Y axis in the second needle cover part 16. The inclined portion 18 is a portion where the outer peripheral portion 40 of the needle cover opening detection label 1 extends obliquely with respect to the direction of the Y axis. Two inclined portions 18 are arranged in the second needle cover part 16. One inclined portion 18 is arranged at the end of the second needle cover part 16 in the positive direction of the Y axis. The other inclined portion 18 is arranged at the end of the second needle cover part 16 in the negative direction of the Y axis. Both inclined portions 18 are inclined in a direction that shortens the length of the second needle cover part 16 in the direction of the Y axis.

[0032] 5A indicates the length in the Y-axis direction of the second needle cover part 16 at the end in the negative Y-axis direction of the second needle cover part 16. The length 63 is shorter than the length 62.

[0033] By providing the inclined portion 18 on the second needle cover part 16, it is possible to prevent wrinkles and the like from forming on the needle cover opening detection label 1 when the needle cover opening detection label 1 is affixed to the medical needle 2.

[0034] The label body 10 has a first cut 21, a second cut 22, and a third cut 23 formed therein.

[0035] Of the outer periphery 40 extending in the X-axis direction of the needle base portion 12 and the first needle cover portion 15, the side located on the positive side of the Y-axis is designated as the first side 41, and the side located on the negative side of the Y-axis is designated as the second side 42.

[0036] The first slit 21 extends in the negative direction of the Y-axis from the first side 41. The tip of the first slit 21 is defined as a first end 31.

[0037] The second slit 22 is a slit that extends in a direction intersecting with the first slit 21. The second slit 22 extends in a direction intersecting with the boundary line 9 when the needle cover opening detection label 1 is affixed to the medical needle 2. The second slit 22 is formed in the needle cover portion 14.

[0038] The end of the second cut 22 that is closer to the first cut 21 is referred to as a second end 32. The end of the second cut 22 that is farther from the first cut 21 is referred to as a third end 33.

[0039] The third cut 23 is a cut that extends in the positive direction of the Y axis from the second side 42. The tip of the third cut 23 is defined as a fourth end 34.

[0040] The first slit 21 and the third slit 23 are disposed on approximately the same straight line. The needle cover opening detection label 1 is affixed to the medical needle 2 so that the first slit 21 and the third slit 23 overlap the boundary line 9.

[0041] The removal of the needle cover 7 from the hub 3 will now be described. The needle cover 7 and the hub 3 are joined via a screw. An arrow 70 in Fig. 4 indicates the direction in which the needle cover 7 is rotated when removing the needle cover 7 from the hub 3. The needle cover 7 is removed from the hub 3 by rotating the needle cover 7 in the direction of the arrow 70.

[0042] Arrow 71 in Fig. 5A indicates the direction of rotation of first needle cover part 15 when needle cover 7 is rotated in the direction of arrow 70 in Fig. 4. When first needle cover part 15 is rotated in the direction of arrow 71, tears are generated extending from first cut 21 and third cut 23. Then, first cut 21 and third cut 23 are connected, and hub part 12 and first needle cover part 15 are separated. The generation of tears between hub part 12 and first needle cover part 15 makes it apparent from the outside that needle cover 7 has been removed from hub 3 once.

[0043] We will explain the state of the needle cover opening detection label 1 after the needle cover 7 has been removed from the needle hub 3. Fig. 6 is a diagram showing the needle hub 3 after the needle cover 7 has been removed from the needle hub 3. Fig. 7 is a diagram showing the state in which the needle cover 7 has been removed from the needle hub 3 and then returned to the needle hub 3.

[0044] When the needle cover 7 is removed from the hub 3, as shown in Fig. 6, the hub portion 12 remains on the hub 3. It is the hub portion 12 that remains on the hub 3, and the needle cover portion 14 does not remain on the hub 3. By not leaving the needle cover portion 14 on the hub 3, the aesthetic appearance of the hub 3 is not marred. In addition, the operability of the hub 3 can be improved. This is because if fragments of the label body 10 are attached to the hub 3 in addition to the hub portion 12, it will be time-consuming to remove the fragments.

[0045] In the needle cover opening detection label 1 of this embodiment, the first cut 21 and the third cut 23 are formed along the boundary line 9. Therefore, the hub part 12 and the needle cover part 14 tend to tear linearly along the first cut 21 and the third cut 23. Therefore, it is possible to prevent only the needle hub part 12 from remaining on the needle hub 3 and the needle cover part 14 from remaining on the needle hub 3.

[0046] In addition, the needle cover opening detection label 1 of this embodiment makes it easier to recognize from the outside that the needle cover 7 has been removed from the needle base 3, even if the removed needle cover 7 is returned to the needle base 3, as shown in Figure 7.

[0047] The reason why it is easier to recognize is that a tear has occurred along the second cut 22. The second cut 22 extends in a direction intersecting with the boundary line 9. Therefore, even when the removed needle cover 7 is returned to the needle hub 3 so that the needle hub portion 12 and the needle cover portion are continuous, it is possible to easily recognize from the outside that the needle cover 7 has been removed once.

[0048] Furthermore, in the needle cover opening detection label 1 of this embodiment, even if a tear occurs along the direction intersecting with the boundary line 9, the label body 10 can be torn without any part of the needle cover portion 14 remaining on the needle base 3.

[0049] Returning to Fig. 5A, the positional relationship of the cuts will be described. Length 50 in Fig. 5A indicates the shortest distance between the second end 32 and the second side 42. Length 51 in Fig. 5A indicates the shortest distance between the third end 33 and the outer periphery 40 of the label body 10 on the needle hub portion 12 side of the third end 33. Length 50 is shorter than length 51. Because length 50 is shorter than length 51, the needle cover portion 14 is less likely to remain on the needle hub 3.

[0050] When the needle cover 7 is rotated in the direction of the arrow 70 shown in Fig. 4, the needle cover part 14 rotates in the direction of the arrow 71 shown in Fig. 5A in conjunction with the rotation of the needle cover 7. This rotation causes the label body 10 to start tearing in the negative direction of the Y axis from the second end 32 of the second cut 22. Meanwhile, the label body also starts tearing in the negative direction of the Y axis from the third end 33 of the second cut 22. In particular, the label body 10 starts tearing from the third end 33 of the second cut 22 in a direction closer to the boundary line 9, i.e., in a direction closer to the needle hub part 12 than the third end 33.

[0051] In the needle cover opening detection label 1 of this embodiment, the length 50 is shorter than the length 51. Therefore, the tear is connected between the second end 32 and the second side 42 before the tear is connected between the third end 33 and the outer periphery 40 of the label body 10 on the needle hub portion 12 side of the third end 33. As a result, the needle cover portion 14 and the needle hub portion 12 are separated before a part of the needle cover portion 14 is cut off from the needle cover portion 14. Therefore, the needle cover portion 14 is unlikely to remain on the needle hub 3.

[0052] Next, the relationship between the second cut 22 and the first cut 21 and the third cut 23 will be described. Length 52 in FIG. 5A indicates the distance between the second end 32 of the second cut 22 and the first end 31 of the first cut 21. Length 53 in FIG. 5A indicates the distance between the second end 32 of the second cut 22 and the fourth end 34 of the third cut 23. When length 52 is shorter than length 53, it is preferable that the length obtained by subtracting length 52 from length 53 is shorter than length 51.

[0053] When the needle cover part 14 rotates in the direction of the arrow 71, the label body 10 starts to tear in the direction along the Y-axis from the first end 31 of the first cut 21 and the fourth end 34 of the third cut 23. From the first end 31, the label body 10 tears in the negative direction of the Y-axis. From the fourth end 34, the label body 10 tears in the positive direction of the Y-axis.

[0054] 5A, the length 52 indicating the distance between the second end 32 of the second cut 22 and the first end 31 of the first cut 21 is shorter than the length 53 indicating the distance between the second end 32 of the second cut 22 and the fourth end 34 of the third cut 23. Therefore, the tear in the label body 10 is connected between the second end 32 and the first end 31 before it is connected between the second end 32 and the fourth end 34.

[0055] When the tear is connected between the second end 32 and the first end 31, the tear advances from the fourth end 34 toward the second end 32 by a length approximately equal to the length 52. Therefore, the length obtained by subtracting the length 52 from the length 53 is made shorter than the length 51. As a result, the tear that has progressed from the fourth end 34 is connected to the second end 32 before the tear is connected between the third end 33 and the outer peripheral portion 40 of the label body 10 on the needle hub portion 12 side of the third end 33. As a result, the needle cover portion 14 and the needle hub portion 12 are separated before a part of the needle cover portion 14 is cut off from the needle cover portion 14. Therefore, the needle cover portion 14 is less likely to remain on the needle hub 3.

[0056] It is preferable that length 53 indicating the distance between the second end 32 and the fourth end 34 is shorter than length 51 indicating the shortest distance between the third end 33 and the outer periphery 40 of the label body 10 on the needle base portion 12 side of the third end 33.

[0057] It is possible that a tear proceeding from the second end 32 in the negative direction of the Y axis does not connect with a tear proceeding from the fourth end 34 of the third cut 23 in the positive direction of the Y axis. For example, this is the case when a tear proceeding from the fourth end 34 in the positive direction of the Y axis is greatly inclined in the positive direction of the X axis. Even in such a case, when the length 53 is shorter than the length 51, the tear is connected between the second end 32 and the fourth end 34 before the tear is connected between the third end 33 and the outer periphery 40 of the label body 10 on the needle hub portion 12 side of the third end 33. As a result, the needle cover portion 14 and the needle hub portion 12 are separated before a part of the needle cover portion 14 is cut off from the needle cover portion 14. Therefore, the needle cover portion 14 is less likely to remain on the needle hub 3.

[0058] The positional relationship between the first slit 21 and the second slit 22 will be described. The needle cover 7 of this embodiment is removed from the needle hub 3 by rotating it in the direction of the arrow 70 as shown in Fig. 4. When the needle cover 7 is rotated in the direction of the arrow 70 in Fig. 4, the first needle cover part 15 rotates in the direction of the arrow 71 in Fig. 5A. The arrow 72 shown in Fig. 5A indicates the direction from the first end 31 of the first slit 21 to the first side 41. In this embodiment, the direction indicated by the arrow 71 and the direction indicated by the arrow 72 are the same.

[0059] Auxiliary line 75 shown in Fig. 5A is an extension of first cut 21. Auxiliary line 76 shown in Fig. 5A is an extension of second cut 22. Angle 78 shown in Fig. 5A is an angle formed by auxiliary line 75 and auxiliary line 76. In needle cover opening detection label 1 of this embodiment, the angle of angle 78 is greater than 90 degrees.

[0060] Because the direction indicated by the arrow 71 and the direction indicated by the arrow 72 are the same direction and the angle of the angle 78 is greater than 90 degrees, it becomes easier to cause the tearing of the label body 10 to proceed along the desired path along the first cut 21 and the second cut 22.

[0061] When the needle cover 7 is rotated in the direction of the arrow 70, a breaking force acts in the negative direction of the Y axis on the first end 31 of the first slit 21 and the second end 32 of the second slit 22. Also, when the needle cover 7 is a screw-type cap, a force acts in the negative direction of the X axis on the first end 31 of the first slit 21 and the second end 32 of the second slit 22 as the needle cover 7 rotates. The resultant force of the negative Y axis force and the negative X axis force is a force inclined with respect to the axis in the negative Y axis and negative X axis directions.

[0062] When the direction indicated by the arrow 71 and the direction indicated by the arrow 72 are almost the same direction, the direction of the resultant force of the two forces is likely to be close to the direction from the first end 31 to the second end 32. Also, when the angle of the angle 78 is greater than 90 degrees, the direction of the resultant force of the two forces is likely to be close to the direction in which the second cut 22 extends. As a result, the tearing of the label body 10 is likely to proceed along the desired path.

[0063] The label body 10 shown in FIG. 5A includes the first cut 21 and the third cut 23 as cuts extending in the Y-axis direction. However, the cut extending in the Y-axis direction may be either the first cut 21 or the third cut 23. When the cuts extending in the Y-axis direction are combined into one, it is preferable to arrange the cut closer to the second end 32 of the second cut 22. This makes it easier for the cut extending in the Y-axis direction to be connected to the second cut 22. Alternatively, when the needle cover 7 is removed from the needle hub 3 while being rotated, it is preferable that the cut along the Y-axis is such that the direction from the end of the cut to the outer periphery 40 of the label body 10 is the same as the direction of rotation of the needle cover 7. This allows the tear in the label body 10 to be smoothly extended from the end of the cut.

[0064] Furthermore, the label body 10 may have a line 19 that is a different color from the other parts of the label body 10. For example, if the label body 10 is white, the line 19 may be black. If the label body 10 is torn over the line 19, it will be easier to see that the needle cover 7 has been removed.

[0065] Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various changes, modifications, and combinations are possible.

[0066] For example, the shape of the cut is not limited to the example shown in Fig. 5A. Other shapes of the cut will be described with reference to Fig. 8 to Fig. 10. Fig. 8 to Fig. 10 are diagrams showing needle cover opening detection labels 1 having different cut shapes.

[0067] The needle cover opening detection label 1 shown in Fig. 8 has a different slit from the needle cover opening detection label 1 shown in Fig. 5A. The needle cover opening detection label 1 shown in Fig. 8 has only one slit along the Y axis. The needle cover opening detection label 1 shown in Fig. 8 has a first slit 21 but does not have a third slit 23.

[0068] Even though there is only one cut along the Y axis, the first cut 21, the shortest distance 50 between the second end 32 of the second cut 22 and the second side 42 is shorter than the shortest distance 51 between the third end 33 of the second cut 22 and the outer periphery 40 of the label body 10 on the needle hub portion 12 side of the third end 33, so that it is possible to provide a needle cover opening detection label 1 that makes it easy to see that the needle cover 7 has been removed from the needle hub 3 once, similar to the needle cover opening detection label 1 shown in Figure 8.

[0069] The needle cover opening detection label 1 shown in Fig. 9 has a slit located symmetrically with respect to the X-axis compared to the needle cover opening detection label 1 shown in Fig. 8. Therefore, in the needle cover opening detection label 1 shown in Fig. 9, the first slit 21 is located on the outer periphery 40 on the start side of the arrow 71 corresponding to the rotation direction of the needle cover 7, rather than on the end side.

[0070] Even with the cut arrangement as shown in Figure 9, the shortest distance 50 between the second end 32 of the second cut 22 and the second side 42 is shorter than the shortest distance 51 between the third end 33 of the second cut 22 and the outer periphery 40 of the label body 10 on the needle base portion 12 side of the third end 33, so that it is possible to provide a needle cover opening detection label 1 that makes it easy to see that the needle cover 7 has been removed from the needle base 3 once, similar to the needle cover opening detection label 1 shown in Figure 8.

[0071] The needle cover opening detection label 1 shown in Fig. 10 has different lengths of the first slit 21 and the third slit 23 compared to the needle cover opening detection label 1 shown in Fig. 5A. Taking the first slit 21 as an example, in the needle cover opening detection label 1 shown in Fig. 5A, the length of the first slit 21 in the Y-axis direction is 80. In the needle cover opening detection label 1 shown in Fig. 10, the length of the first slit 21 in the Y-axis direction is 82. The length 82 is shorter than the length 80.

[0072] As shown in Fig. 10, the length of the first slit 21 and the length of the third slit 23 can be changed as appropriate. Even if the length of the first slit 21 and the length of the third slit 23 are changed as appropriate, the shortest distance 50 between the second end 32 of the second slit 22 and the second side 42 is shorter than the shortest distance 51 between the third end 33 of the second slit 22 and the outer periphery 40 of the label body 10 on the needle hub portion 12 side of the third end 33, so that it is possible to provide a needle cover opening detection label 1 that makes it easy to tell that the needle cover 7 has been removed from the needle hub 3 once, similar to the needle cover opening detection label 1 shown in Fig. 8.

[0073] It should be noted that the first cut 21, the second cut 22, and the third cut 23 are not limited to continuous cutting lines, and the first cut 21, the second cut 22, and the third cut 23 may be discontinuous cutting lines such as perforations.

[0074] An auxiliary cut may be formed between the cuts. Fig. 5B is a diagram showing the needle cover tamper detection label 1 with the auxiliary cut 25 formed. The auxiliary cut 25 is a discontinuous cutting line formed between an end of a cut and an end of another cut. An example of a discontinuous cutting line is a perforation.

[0075] The difference between the needle cover opening detection label 1 shown in Figure 5B and the needle cover opening detection label 1 shown in Figure 5A is that the needle cover opening detection label 1 shown in Figure 5B has an auxiliary cut 25 formed between the first end 31 of the first cut 21 and the second end 32 of the second cut 22.

[0076] By forming the auxiliary cut 25, the tearing of the label body 10 is facilitated to proceed in a desired direction.

[0077] The shape of the cut is not limited to the shape shown in Fig. 5A. Other shapes of the cut will be described with reference to Figs. 5C to 5F.

[0078] The cut shown in FIG. 5C and the cut shown in FIG. 5A have different directions of extension of the first cut 21. The first cut 21 shown in FIG. 5A extends in the direction of rotation of the first needle cover part 15 when the needle cover 7 is rotated in the direction of the arrow 70 in FIG. 4, that is, in a direction parallel to the arrow 71. In contrast, the first cut 21 shown in FIG. 5C extends in a direction inclined from the direction shown by the arrow 71 so that the first end 31 approaches the second end 32 of the second cut 22. This makes it easier for the tear in the label body 10 to connect between the first end 31 and the second end 32.

[0079] The difference between the cut shown in FIG. 5D and the cut shown in FIG. 5A is whether the second cut 22 is a straight line or a curved line. The second cut 22 shown in FIG. 5A is a straight line. In contrast, the second cut 22 shown in FIG. 5D is a curved line that protrudes in the positive direction of the Y axis. By making the second cut 22 a curved line, the distance over which the label body 10 tears can be increased. This makes it easier to visually confirm that the label is torn when detecting whether the label has been opened.

[0080] As shown in FIG. 5E, when the second cut 22 is curved, it may be curved so as to protrude in the negative direction of the Y-axis.

[0081] The cut shown in FIG. 5F is different from the cut shown in FIG. 5A in that the second cut 22 is a straight line or a combination of two straight lines. The second cut 22 shown in FIG. 5A is a straight line. In contrast, the second cut 22 shown in FIG. 5F includes a first straight line portion 222 and a second straight line portion 223 connected at a connection point 221. The first straight line portion 222 and the second straight line portion 223 extend in different directions. The angle between the first straight line portion 222 and the first cut 21 can be 100 degrees or more, similar to the second cut 22 shown in FIG. 5A. The angle between the second straight line portion 223 and the first cut 21 can be, for example, 90 degrees.

[0082] Because the second cut 22 includes a first straight portion 222 and a second straight portion 223, when the first needle cover portion 15 rotates and the label body 10 begins to tear, it is possible to achieve both smooth progression of the tear and the ability to position the intended end point of the tear, i.e., the position of the third end 33, at any desired position.

[0083] In addition, the shape of the label body 10 is not limited to the shape shown in FIG. 5A. FIGS. 11 and 12 are diagrams showing other examples of the needle cover opening detection label 1. The break is not shown in FIGS. 11 and 12. As shown in FIG. 11, the inclined portion 18 may not be provided on the needle cover opening detection label 1. When the inclined portion 18 is not provided on the needle cover opening detection label 1, the area of ​​the needle cover portion 14 can be increased. By increasing the area of ​​the needle cover portion 14, the needle cover opening detection label 1 can be made more difficult to peel off from the needle cover 7 even if the needle cover 7 is made of a poorly adhesive material.

[0084] 12, the length 60 of the needle base portion 12 in the Y-axis direction may be the same as the length 62 of the needle cover portion 14 in the Y-axis direction. By having the label body 10 have a constant length in the Y-axis direction, it is possible to easily attach the needle cover opening detection label 1 to the medical needle 2.

[0085] The use of the opening detection label of the present disclosure described as the needle cover opening detection label 1 is not limited to the opening detection of a needle cover. Another example of the use of the opening detection label of the present disclosure is the opening detection of a container with a lid, in particular, the opening detection of a micro-container with a lid. An example of a micro-container with a lid is a vial. A vial is a container used to store injections and the like.

[0086] An example in which the opening detection label is used as a lid opening detection label 100 will be described with reference to Figures 13 and 14. Descriptions of matters similar to those of the needle cover opening detection label 1 described above will be omitted. Figures 13 and 14 show a vial 90 as an example of a container with a lid. The vial 90 comprises a container body 92 and a lid 94. The lid 94 covers an opening 96 of the container body 92. The lid 94 functions as a plug for the opening 96.

[0087] Examples of the type of the lid 94 are a rotating type and a plug-in type. The type of the lid 94 is not limited. Fig. 13 shows a rotating type lid 94. Fig. 14 shows a plug-in type lid 94. The lid 94 shown in Fig. 13 is removed from the container body 92 by rotating the lid 94 in the direction of an arrow 97. The lid 94 shown in Fig. 14 is removed from the container body 92 by pulling the lid 94 in the direction of an arrow 98.

[0088] The lid opening detection label 100 is attached to the vial bottle 90 across the boundary line 9 between the container body 92 and the lid 94.

[0089] When the lid 94 shown in Fig. 13 is rotated in the direction of arrow 97, or when the lid 94 shown in Fig. 14 is pulled out in the direction of arrow 98, the lid opening detection label 100 is torn. By tearing the lid opening detection label 100, it becomes easier to recognize from the outside that the lid 94 has been removed from the container body 92.

[0090] In the label body 10 of the tamper detection label 100, a portion that is placed on the container body 92 is referred to as a container portion 102. In the label body 10, a portion that is placed on the lid 94 is referred to as a lid portion 104. In the tamper detection label 100, the second cut line 22 may be provided in either the container portion 102 or the label body 10.

[0091] Although the present invention has been described above with reference to the preferred embodiment, the present invention is not limited to the above-described preferred embodiment, and various modifications, variations, and combinations are possible. [Explanation of symbols]
