Description

Technical Field

[0001] This invention relates to a resealing-preventing label and a box with a resealing-preventing label. Background Technology

[0002] Medical devices such as catheters are sterilely stored in a bag, which is then placed together with the bag into a box. The box itself is a paper structure with a lid that opens upon opening. Furthermore, a label to prevent unauthorized opening is affixed to the lid of the unopened box. For example, an tamper-evident label as described in Patent Document 1 can be used for this label.

[0003] The tamper-evident label described in Patent Document 1 has strong adhesive strength and is difficult to peel off easily when attached to the lid. Furthermore, even if an attempt is made to reseal the box with another tamper-evident label after the tamper-evident label has been illegally removed, the outer paper of the box will be peeled off along with the tamper-evident label during the opening process, leaving a trace of tampering. Moreover, visually identifying this trace of tampering indicates that the box has been opened, thus preventing further tampering.

[0007] However, regarding the tamper-evident label described in Patent Document 1, in the event of an attempt to illegally open the box, the tamper-evident label can be cut off with a sharp knife, leaving no trace of the opening. Furthermore, if, after illegal opening, another new tamper-evident label is pasted onto the tamper-evident label that was cut off during the opening, it is difficult to distinguish it from an unopened box by appearance, making it difficult to detect illegal opening.

[0008] The purpose of this invention is to provide a resealing prevention label that can prevent tampering, such as unauthorized opening of the box and subsequent resealing, and a box with the resealing prevention label.

[0009] The above objectives can be achieved by the following (1) to (12) of the present invention.

[0010] (1) A resealing prevention label, characterized in that it comprises:

[0011] A substrate formed into a sheet shape;

[0012] An adhesive layer is formed on one side of the substrate and has adhesive properties; and

[0013] An anti-adhesion layer is a layer formed on the other side of the substrate, which prevents adhesive materials from sticking together when they are overlapped.

[0014] The adhesive-resistant layer has multiple small protrusions that are formed.

[0095] Hereinafter, preferred embodiments of the label and the labeled box of the present invention shown in the accompanying drawings will be described in detail.

[0096] <First Embodiment>

[0097] Figure 1 is a top plan view of the label of the present invention (first embodiment) viewed from the front side. Figure 2 is a view viewed from the back side of Figure 1 the label shown in , which is a top plan view. Figure 3 is a cross-sectional view taken along line A-A in Figure 1 . Figure 4 is a perspective view of a box (labeled box) with the label shown in Figure 1 adhered thereon. Figure 5 is a perspective view showing the opened state of the labeled box shown in Figure 4 . Figures 6-9 are respectively partial cross-sectional views sequentially showing the unintentional opening state of the labeled box shown in Figure 4 . It should be noted that, for convenience of description below, in Figure 3 ( Figure 10 and Figure 11 are also the same), the upper side is referred to as "front" or "upper (above)", and the lower side is referred to as "back" or "lower (below)".

[0098] Figure 1 The tamper-evident label 1 shown in is a label that is used by being adhered to a box or the like for accommodating medical instruments such as catheters 100. In the present embodiment, the box 9 shown in Figure 4 is taken as an example of a box. Furthermore, the box 9 adhered with the tamper-evident label 1 circulates in medical sites as a labeled box 10 with a tamper-evident label. In addition, it is preferable that the state of the near side of the paper surface in the labeled box 10 with a tamper-evident label is the same as the inner side of the paper surface in Figure 4 , and the inner side Figure 4 is the same as the aforementioned. In addition, the perforation line 931 described later may be omitted on the inner side.

[0099] First, the tamper-evident label will be described in detail.

[0100] As shown in Figure 1 , the tamper-evident label 1 of the present embodiment has a rectangular shape with rounded corners 11 when viewed from above. The length L in the longitudinal direction (hereinafter referred to as "x direction") of the tamper-evident label 1 1-1There are no particular limitations; for example, 10mm to 40mm is preferred, and 15mm to 30mm is more preferred. The length L of the label 1 for preventing resealing is defined as follows: (hereinafter referred to as the "y-direction") 1-2 There are no particular limitations, but it is preferred to be between 10mm and 30mm, and even more preferred to be between 15mm and 25mm.

[0101] It should be noted that when viewing the resealing prevention label 1 from above, its shape is not limited to a rectangle with rounded corners. For example, it can also be a square, circle, or oval with rounded corners, or other shapes. 1-1 >L 1-2 Even when using transparent plain labels, it is easy to determine the pasting direction, making it a better choice.

[0102] like Figure 3 As shown, the resealable label 1 is formed of a laminate, including: a substrate 2 formed in sheet form; an adhesive layer 3 formed in layers on the back (one side) 21 side of the substrate 2; an anti-adhesion layer 4 formed in layers on the surface (other side) 22 side of the substrate 2; and a coloring layer 5 formed in layers between the substrate 2 and the anti-adhesion layer 4. Furthermore, the resealable label 1 is used with the anti-adhesion layer 4 as the front side and the adhesive layer 3 as the back side. It should be noted that one or more additional layers may be formed between the layers.

[0103] The substrate 2 is a flexible film with a thickness t2 uniformly distributed along the surface direction of the resealing prevention label 1. The thickness t2 is not particularly limited, but it is preferably 0.01 mm to 0.15 mm. If it is 0.03 mm to 0.08 mm, it is more preferred because it is a thickness that makes it easy to achieve L-shaped adhesion at the corner.

[0104] As a constituent material of the substrate 2, various thermoplastic elastomers can be used, among which polyethylene terephthalate (PET) is particularly preferred. In addition, the substrate 2 is preferably colorless and transparent.

[0105] An adhesive layer 3 with adhesive properties is formed on the back side 21 of the substrate 2. The resealing and anti-re-sealing label 1 is attached to the box body 9 by means of the adhesive layer 3.

[0106] The adhesive layer 3 is mainly composed of an adhesive (adhesive composition). Any type of adhesive, such as a rubber-based adhesive, an acrylic adhesive, or a silicone adhesive, can be used. Furthermore, the adhesive layer 3 is preferably colorless and transparent. The thickness t3 of the adhesive layer 3 is not particularly limited.

[0107] A coloring layer 5 is formed on the surface 22 of the substrate 2. The color of the coloring layer 5 is different from that of the adhesive resist layer 4, for example, if the adhesive resist layer 4 is colorless and transparent. Furthermore, the color can be either colored or non-colored, but colored is preferred. Additionally, there is no particular limitation on the color; for example, green can be chosen. Figure 4 As shown, the perforation line 931 is formed in a way that surrounds a portion of the resealing prevention label 1. Thus, the coloring layer 5 makes the finger hook portion 932, which serves as the opening point, more prominent. Furthermore, as previously described, the cap 92 can be opened directly by hooking a finger onto the finger hook portion 932 during opening.

[0108] The coloring layer 5 is formed using various printing methods such as offset printing, screen printing, and inkjet printing, employing various inks such as UV-curable inks. The ink contains pigments or dyes as coloring materials. Furthermore, the coloring layer 5 preferably has transparency.

[0109] The thickness t5 of the coloring layer 5 is uniform along the surface direction of the resealability-preventing label 1. There is no particular limitation on the thickness t5; for example, it is preferably 0.005 mm to 0.04 mm, and more preferably 0.01 mm to 0.03 mm. It should be noted that the coloring layer 5 can be omitted in the resealability-preventing label 1.

[0110] An anti-adhesion layer 4 is formed on top of the coloring layer 5. As described later, the anti-adhesion layer 4 is a layer that prevents the label 300, which is an adhesive material, from sticking when it is overlapped (see reference). Figure 8 , Figure 9 ).

[0111] like Figure 3 As shown, the adhesive prevention layer 4 has a plurality of small protrusions 41 that protrude upwards and a base layer 42 for forming the plurality of small protrusions 41.

[0112] Like the coloring layer 5, the anti-adhesion layer 4 is formed using various printing methods such as offset printing, screen printing, and inkjet printing, employing various inks, including UV-curable inks. Furthermore, the anti-adhesion layer 4 sequentially comprises a base layer 42 and small protrusions 41. It should be noted that pigments or dyes used as coloring materials are preferably omitted from the anti-adhesion layer 4. Additionally, it is preferable that the anti-adhesion layer 4 is transparent.

[0113] The thickness t of the base layer 42 42 The thickness t is uniform along the direction of the resealing prevention label 1. 42 There are no particular limitations; for example, a thickness of 0.005 mm to 0.05 mm is preferred, and more preferably 0.01 mm to 0.03 mm. Small protrusions 41 can be stably formed through this base layer 42.

[0114] Multiple small protrusions 41 are formed on the base layer 42. These small protrusions 41 can also be formed by various roughing processes such as shot peening, but as mentioned above, they are preferably formed by various printing methods. Thus, multiple small protrusions 41 can be formed in a regular arrangement. Here, "regular arrangement" means arranged according to a fixed rule. In this embodiment, in... Figure 1 The image shows an example of a regular configuration. It should be noted that, as a regular configuration, it is not limited to... Figure 1 The configuration shown can also be a row and column configuration, for example, with one or more columns along the long side and one or more columns along the short side.

[0115] like Figure 1 As shown, multiple small protrusions 41 are arranged in 12 columns along the y-direction. The following... Figure 1 The columns on the left are sequentially labeled "Column 1 α1", "Column 2 α2", "Column 3 α3", "Column 4 α4", "Column 5 α5", "Column 6 α6", "Column 7 α7", "Column 8 α8", "Column 9 α9", "Column 10 α1", and so on. 10 "Column 11 α" 11 "Column 12 α" 12 ".

[0116] Belongs to column 1 α1 to column 12 α 12 The number of small protrusions 41 in each column is the same. The number of small protrusions 41 is in Figure 1 The configuration shown contains four elements, but is not limited to this.

[0117] By regularly arranging the multiple small protrusions 41 in the manner described above, the adhesive force of the label 300 (described later) can be uniformly reduced along the surface direction of the resealing prevention label 1.

[0118] When viewing the resealing prevention label 1 from above, it is preferable that the total area of ​​the plurality of small protrusions 41 is less than 60% of the area of ​​the resealing prevention label 1, and more preferably 30% to 50%.

[0119] The preferred protrusion height (thickness) t of the small protrusion 41 41 The thickness is between 0.01mm and 0.1mm, and more preferably between 0.03mm and 0.07mm. It should be noted that the protrusion height t of each small protrusion 41... 41 exist Figure 1 The structures shown are the same, but they can be different.

[0120] The small protrusion 41 forms a circle when the resealing of the label 1 is viewed from above. Its diameter is preferably [missing information]. The thickness should be between 0.5mm and 3.5mm, with a more preferred thickness between 1.5mm and 2.5mm. It should be noted that the diameter of each small protrusion 41... exist Figure 1 The configuration shown is the same, but it can also be different. In addition, the shape of the small protrusion 41 when viewed from above is not limited to a circle; for example, it can also be an ellipse or a polygon, or it can be linear.

[0121] By satisfying the above numerical range, it can be coordinated with the regular configuration of the aforementioned small protrusions 41 to properly exert the overlapping adhesive prevention effect of the resealing prevention label 1 described later.

[0122] The resealing prevention label 1 constructed as described above preferably has light transmittance from the adhesive prevention layer 4 on the front side to the adhesive layer 3 on the back side, that is, as shown in the image. Figure 2 As shown, the transparency is preferably such that the small protrusions 41 are visually recognizable even when viewed from the back side. Thus, as... Figure 4 As shown, even when the label 1 is resealed to prevent overlapping and pasted on the barcode 99, the barcode 99 can still be read using a barcode reader (not shown).

[0123] Next, let's describe box 9.

[0124] like Figure 4 As shown, the box 9 includes a hollow main body 91 and a cover 92 integrally formed with the main body 91. It should be noted that the box 9 is preferably made of paper material such as thick paper.

[0125] The main body 91 has a top plate 93, a bottom 94 opposite to the bottom of the top plate 93, and two side portions 95 connecting the top plate 93 and the bottom 94, which can store the medical device 100 in the space 96 surrounded by the above portions.

[0126] It should be noted that the medical device 100 is stored in a sterile state in a bag (not shown), preferably stored together with the bag in space 96.

[0127] A cover 92 is integrally formed at the bottom 94. For example... Figure 5 As shown, cover 92 is opened when the box 9 is opened. By opening cover 92, the main body 91 is thus opened. Figure 5 The paper has an opening near the front, forming an access port 97. The medical device 100 is removed from the space 96 through the access port 97.

[0128] like Figure 4 As shown, the cover 92 covers the outlet 97 before opening, and then the insertion part 98 is inserted into the main body 91 (outlet 97).

[0129] Furthermore, a perforated line 931 is formed on the top plate portion 93 where it overlaps with the insertion portion 98 in the inserted state. The perforated line 931 functions as an opening aid for the cover 92. When the cover 92 is opened, the trapezoidal portion surrounded by the perforated line 931 serves as a finger hook portion 932, allowing a finger to be hooked onto this finger hook portion 932 and pressed directly into the inside of the housing 9. As a result, the top plate portion 93 breaks due to the perforated line 931, and the cover 92 is peeled off from the top plate portion 93 along with the finger hook portion 932 and the resealed anti-tag 1, thereby making it easy to open the cover 92.

[0130] It should be noted that the housing 9 is equipped with a barcode 99, which serves as an information display unit carrying and displaying various information related to the medical device 100. The location of the barcode 99 is not particularly limited, but... Figure 4 As shown, in this embodiment, cover 92 is used as an example. Alternatively, a display label containing a barcode, product name, product code, etc., can be affixed, and then overlapped with the display label to prevent resealing, label 1. In addition, barcode 99 is printed on the sealing part 990, for example, and attached to the box body 9 together with the sealing part 990.

[0131] The following explains how to use label 1 to prevent resealing.

[0132] like Figure 4 As shown, the resealing prevention label 1 is affixed across the finger hook portion 932 of the top plate portion 93 and the cover 92 for sealing the cover 92.

[0133] While trying to Figure 6 If the box 10 with the resealability prevention label shown is opened in violation of regulations, such as Figure 7 As shown, the resealability label 1 can be cut off by using a sharp tool such as a cutter 200, thereby releasing the seal of the resealability label 1 on the cover 92. The cutting point of the resealability label 1 can be the portion at the boundary between the top plate portion 93 facing the main body 91 and the cover 92.

[0134] Then, after being illegally opened, such as Figure 8 As shown, for example, if a new colorless and transparent label 300 of the same size as the resealability label 1 is overlapped and pasted on the resealability label 1 that was cut off when it was opened, it is difficult to distinguish it from an unopened box 10 with the resealability label, and it is difficult to know that it was opened illegally.

[0135] However, as mentioned earlier, the resealing prevention label 1 has an adhesive-resistant layer 4 with small protrusions 41 on its uppermost layer. Therefore, the contact area between the label 300 and the resealing prevention label 1 can only be the size corresponding to the small protrusions 41, resulting in a reduced adhesive force between the label 300 and the resealing prevention label 1. Thus, as... Figure 9 As shown, this method prevents label 300 from overlapping and being peeled off from resealing prevention label 1. In this way, even if label 300 is overlapped with resealing prevention label 1, resealing prevention label 1 can still prevent overlapping and adhering.

[0136] As shown above, based on the resealability prevention label 1, if the box 10 bearing the resealability prevention label is illegally opened, the illegal opening can be confirmed by visually identifying that the resealability prevention label 1 has been cut off. Furthermore, it can also prevent tampering with the opening using the adhesive label 300.

[0137] In addition, not only can a resealability prevention label 1 be affixed to one bottom 94 side of the box, but unauthorized opening can also be prevented on the opposite side by affixing the resealability prevention label 1 to the other bottom (not shown) on the opposite side as well.

[0138] <Second Implementation>

[0139] Figure 10 This is a cross-sectional view showing a second embodiment of the label of the present invention.

[0140] The following description refers to the figure and illustrates a second embodiment of the label and the labeled box of the present invention, but mainly focuses on the differences from the aforementioned embodiments, omitting descriptions of identical items.

[0141] This embodiment is the same as the first embodiment except for the different arrangement of the small protrusions.

[0142] like Figure 10 As shown, a plurality of small protrusions 41 are arranged in a stepped manner along the thickness direction of the resealability label 1. In this embodiment, the plurality of small protrusions 41 are divided into two layers along the thickness direction of the resealability label 1, namely, a lower layer of first small protrusions 411 and an upper layer of second small protrusions 412. The arrangement (configuration mode) of the first small protrusions 411 is the same as that of the small protrusions 41 in the first embodiment. In addition, a second small protrusion 412 is arranged between each adjacent first small protrusion 411. Thus, the arrangement of the first small protrusions 411 is the same as that of the second small protrusions 412. Therefore, when the resealability label 1 is viewed from above, the total area of ​​the plurality of first small protrusions 411 is the same as the total area of ​​the plurality of second small protrusions 412.

[0143] This design allows for a more effective way to prevent overlapping adhesive bonding.

[0144] It should be noted that the configuration of the first small protrusion 411 is the same as that of the second small protrusion 412, but it is not limited to this and can be different.

[0145] In addition, when viewing the resealing prevention label 1 from above, the total area of ​​the plurality of first small protrusions 411 is the same as the total area of ​​the plurality of second small protrusions 412, but it is not limited to this and they may be different.

[0146] Alternatively, the shapes of the first small protrusion 411 and the second small protrusion 412 can also be different.

[0147] <Third Implementation>

[0148] Figure 11 This is a cross-sectional view showing the third embodiment of the label of the present invention.

[0149] The following description, with reference to the figure, illustrates a third embodiment of the label and the labeled box of the present invention, but mainly focuses on the differences from the aforementioned embodiments, omitting descriptions of identical items.

[0150] This embodiment is the same as the first embodiment except for the different composition of the adhesive prevention layer.

[0151] like Figure 11 As shown, in this embodiment, the anti-adhesion layer 4 is a layer in which the base layer 42 is omitted. Therefore, the resealing anti-retrieval label 1 of this embodiment is thinner than the resealing anti-retrieval label 1 of the first embodiment, thereby increasing light transmittance due to its thinner thickness. Consequently, when reading the barcode 99 attached to the box 9 using a barcode reader, the reading is more stable.

[0152] The above description of the illustrated embodiments illustrates the label and the labeled box of the present invention, but the present invention is not limited thereto. The various parts constituting the label and the labeled box can be replaced with any configuration that can perform the same function. In addition, any additional components may be added.

[0153] In addition, the label and the labeled box of the present invention may also be a construction that combines any two or more of the components (features) in the foregoing embodiments.

[0154]

[0158] (Example 1)

[0159] Production Figure 1 The label 1 shown is for preventing resealing (size: 24mm in length, 20mm in width). This label 1 is used as a sample and is pasted onto the backing paper (size: 50mm in length, 30mm in width) which serves as the test board.

[0160] Furthermore, OPP tape (size: 200mm in length, 18mm in width) as label 300 was pasted onto the resealing anti-overlap label 1 on the backing paper. In this state, tests 1 and 2 were conducted respectively. The stretching speed of the OPP tape in each test was set to 300mm / min.

[0161] (Comparative Example 1)

[0162] Except for omitting the adhesive backing layer, the same label as in Example 1 was made, and the same adhesive strength test as in Example 1 was conducted.

[0163] 2. Test Results

[0164] The test results for the adhesion test of Example 1 and the test results for the adhesion test of Comparative Example 1 are shown in the table below.

[0165] Table 1

[0166] Table 1

[0167] Example 1 300mm / min 48 Comparative Example 1 300mm / min 100

[0168] As shown in Table 1, when the adhesive force in Comparative Example 1 was set to 100, the adhesive force decreased in the adhesive force test for Example 1. This indicates that the adhesive force of the OPP tape decreased due to the label in Example 1. It should be noted that the values ​​in Example 1 are the average adhesive force over a stable period excluding the period immediately before and near the end of the test.
