Description

  The present invention relates to a protective seal that can be attached to a predetermined member, and more particularly to a protective seal that can easily determine whether or not the predetermined member has been used.

  In recent years, protective seals have been attached to certain parts that you want to identify as unused, such as infusion bags that contain infusions such as amino acid infusions, electrolyte infusions, sugar infusions, and fat emulsions for infusions. (For example, see Patent Document 1).

JP, 2007-117211, A

  However, the protective seal attached to a predetermined member as described above is, for example, a malicious one that tries to mix a foreign substance into the infusion bag, but when the protective seal is peeled off, the protective seal is broken by the peeling. If a protective seal is attached to the above-mentioned predetermined member again after foreign matter is mixed in, there is no trace of peeling, so it is possible to determine whether or not the predetermined member has been used. There was the problem of being very difficult.

  Therefore, in view of the above problems, it is an object of the present invention to provide a protective seal that can easily determine whether or not a predetermined member is used.

  The above-mentioned object of the present invention is achieved by the following means. In addition, although the reference numerals of the embodiments described later are given in the parentheses, the present invention is not limited thereto.

According to the protective seal of claim 1, a protective seal main body (10) attachable to a predetermined member (for example, an infusion bag T),
A grip portion (20) that is integrally provided on the protective seal body (10) and that can be gripped by a user when the protective seal body (10) is peeled from the predetermined member (for example, the infusion bag T). Has,
A plurality of slits (10b) are formed inward in an outer peripheral portion (outer periphery 10a) of the protective seal body (10).

  Further, according to the invention of claim 2, in the protective seal according to claim 1, the user uses the gripping part (20) in the protective seal body (10), When the main body (10) is peeled off from the predetermined member (for example, the infusion bag T), a part (10B) of the protective seal main body (10) is ruptured in the peeling direction (arrow P1 direction). A perforation (10d) that induces the breakage is formed.

  Furthermore, according to the invention of claim 3, in the protective seal according to claim 2, a part of the perforation (10d) is a perforation (third perforation 10d3) inclined inward. Is formed.

  Next, the effects of the present invention will be described with reference numerals in the drawings. In addition, although the reference numerals of the embodiments described later are given in the parentheses, the present invention is not limited thereto.

  According to the invention of claim 1, when the protective seal body (10) attached to a predetermined member (for example, the infusion bag T) is attempted to be peeled from other than the gripping part (20), the protective seal body (10) is removed. A part (10A) of the protective seal body (10) is broken by the plurality of slits (10b) formed inwardly on the outer peripheral portion (outer periphery 10a) of FIG. As a result, even if a predetermined member (for example, the infusion bag T) is maliciously used, a trace that someone has used the predetermined member (for example, the infusion bag T) will remain. It can be easily determined whether or not it has been used.

  According to the invention of claim 2, when the user uses the gripping portion (20) on the protective seal body (10) and peels the protective seal body (10), the protective seal body (10) is removed. ), A perforation (10d) that induces the fracture is formed in the peeling direction (arrow P1 direction) so that a part (10B) of the A part (10B) of the protective seal body (10) will be broken. This leaves a trace of the protective seal body (10) once peeled off, so that it is possible to easily determine whether or not a predetermined member is used.

  Further, according to the invention of claim 3, one of the protective seal bodies (10) is formed by the perforations (third perforations 10d3) that are formed in a part of the perforations (10d) and incline toward the inner direction. The part (10B) can be accurately (cleanly) broken along the perforations (10d).

  Hereinafter, an embodiment of a protective seal according to the present invention will be specifically described with reference to the drawings. In the following description, the up, down, left, and right directions indicate the up, down, left, and right as viewed from the front of the figure.

  As shown in FIG. 1A, the protective seal 1 includes a protective seal main body 10 having a thin circular shape, and a substantially rectangular grip portion provided so as to project outward from a lower portion of an outer periphery 10 a of the protective seal main body 10. 20 and. The protective seal body 10 can be attached to a predetermined member, and the grip portion 20 is used when the protective seal body 10 attached to the predetermined member is peeled off. The protective seal body 10 and the grip 20 are integrally formed and are made of the same material.

  By the way, as shown in FIG. 1A, a circular non-adhesive layer 14 is formed in the central portion of the protective seal main body 10, and the grip portion 20 is formed as shown in FIG. The non-adhesive layer 24 having a substantially rectangular shape is formed on the entire surface. More specifically, as shown in FIG. 1B, the protective seal body 10 includes a base material 11 having a thickness of about 75 μm such as a polyester film and an aluminum foil, and a coloring material laminated on the surface of the base material 11. Of about 5 μm in thickness, an adhesive layer 13 of about 5 μm in thickness in which an adhesive such as a silicone-based polymer or polyester is laminated on the back surface of the base material 11, and a part of the adhesiveness of the adhesive layer 13. In order to make it inactive (so-called glue removal), it is composed of a non-adhesive layer 14 having a thickness of about 5 μm formed by performing a medium printing or the like on a part of the back surface of the adhesive layer 13. The non-adhesive layer 14 is formed on the central portion of the protective seal body 10 shown in FIG.

  On the other hand, as shown in FIG. 1 (c), the grip portion 20 includes a base material 21 having a thickness of about 75 μm such as a polyester film and an aluminum foil, and a coloring thickness of about 5 μm laminated on the surface of the base material 21. Of the vapor-deposited film 22, an adhesive layer 23 having a thickness of about 5 μm in which an adhesive such as a silicone-based polymer or polyester is laminated on the back surface of the base material 21, and the adhesiveness of a part of the adhesive layer 23 is made inactive. For this reason (so-called glue removal), the non-adhesive layer 24 having a thickness of about 5 μm is formed by performing media printing or the like on a part of the back surface of the adhesive layer 23. The non-adhesive layer 24 is formed entirely on the grip 20 shown in FIG.

  Then, as shown in FIG. 1A, the outer periphery 10a of the protective seal main body 10 configured as described above is spaced at regular intervals inward (toward the center point O in the figure). A slit-shaped slit 10b is formed at the bottom. As will be described later, the slit 10b is provided with a portion 10A of the protective seal body 10 (see FIG. 5B) when the protective seal body 10 attached to a predetermined member is attempted to be peeled from other than the grip portion 20. ) Is formed so as to break.

  On the other hand, when the protective seal body 10 attached to a predetermined member is peeled off by using the grip portion 20, the grip portion 20 is directed in the direction of the arrow P1 shown in FIG. 1A (the bottom portion 20a of the grip portion 20). To the top 10c of the protective seal main body 10), the protective seal main body 10 attached to a predetermined member is peeled off. At this time, as shown in FIG. 1A, perforations 10d that induce the breakage are formed in the protective seal body 10 so that the protective seal body 10 is partially broken. More specifically, as shown in FIG. 1A, the perforations 10d are a pair of linearly extending from the side surface 20b of the grip 20 toward the top 10c of the protective seal body 10. Of the linear first perforation 10d1 and an arc-shaped second perforation 10d2 formed along the outer periphery of the non-adhesive layer 14 for communicating the pair of first perforations 10d1 with each other. ing. Then, when the grip 20 is moved in the direction of the arrow P1 shown in FIG. 1A (from the bottom 20a of the grip 20 to the top 10c of the protective seal body 10), as shown in FIG. A part 10B of the protective seal body 10 is broken along the pair of the first perforation 10d1 and the second perforation 10d2. However, by forming such perforations 10d (a pair of first perforations 10d1 and second perforations 10d2) in the protective seal main body 10, the protective seal affixed to a predetermined member using the gripping portion 20. When the main body 10 is peeled off, a part 10B of the protective seal main body 10 is broken as shown in FIG. This leaves a trace when the protective seal body 10 attached to a predetermined member is peeled off, and thus it is possible to easily determine whether or not the predetermined member is used. As shown in FIG. 1A, a slight gap S is formed between the pair of first perforation 10d1 and second perforation 10d2 and the non-adhesive layer 14 of the protective seal body 10. There is.

  By the way, as shown in FIG. 1A, the first perforation 10d1 is provided with a third perforation 10d3 which is inclined downward toward the bottom portion 20a of the grip portion 20. The third perforation 10d3 is intended to surely break a part 10B of the protection seal body 10 from the protection seal body 10 along a pair of linear first perforations 10d1. That is, when the grip 20 is moved in the direction of the arrow P1 shown in FIG. 1A (from the bottom 20a of the grip 20 toward the top 10c of the protective seal body 10), the first perforation 10d1 is formed. The movement of the third perforation 10d3 is temporarily restricted. As a result, at that portion (the portion where movement is restricted), the breaking stress when breaking the portion 10B of the protective seal body 10 along the pair of first perforations 10d1 is stored, and as shown in FIG. Thus, the part 10B of the protective seal body 10 is accurately (cleanly) broken along the first perforation 10d1. Although the third perforation 10d3 may be formed on the second perforation 10d2, the third perforation 10d3 may not be formed. That is, as shown in the present embodiment, at a location where the first perforations 10d1 are separated from each other, it is highly likely that the breaking stress does not work evenly between the pair of first perforations 10d1. There is a high possibility that the breaking stress will be biased to the first perforation 10d1. Then, there is a high possibility that the part 10B of the protective seal body 10 cannot be accurately (cleanly) broken along the pair of first perforations 10d1. Therefore, as shown in the present embodiment, if the third perforation 10d3 is formed only at a portion where a part of the protective seal main body 10 is broken along the pair of first perforations 10d1 that are separated from each other. It is possible to reduce the situation in which the movement is temporarily restricted in the portion where the third perforation 10d3 is formed, and thus the breaking stress is accumulated and the breaking stress is biased to one of the first perforations 10d1. . Therefore, as shown in the present embodiment, the third perforation 10d3 may be formed only in the pair of first perforations 10d1 that are separated from each other. On the other hand, if the third perforation 10d3 is formed on the second perforation 10d2 as well, the appearance and the breakage can be facilitated.

  Thus, the protective seal 1 configured as described above is used as follows. In the following, an infusion bag will be described as an example of the predetermined member.

  As shown in FIG. 3A, the infusion solution bag T is well known in the related art, and includes a strong peripheral seal portion T1a formed on the periphery of the infusion solution bag body T1. The strong peripheral seal portion T1a is formed by heat welding the inner surfaces of the peripheral portions of the two film sheets forming the infusion bag body T1 while sandwiching the stopper body T2a of the stopper T2. The stopper T2 includes a tubular stopper body T2a for discharging the infusion solution contained in the infusion bag body T1, a rubber stopper T2b inserted into the stopper body T2a and closing the stopper body T2a, and an infusion bag body. It is composed of a cap T2c for fixing the rubber stopper T2b so as not to drop from the mouth plug body T2a when the pressure inside T1 increases or when a hollow needle (not shown) is pulled out from the rubber stopper T2b. . In addition, a plurality (three in the figure) of needle stick marks T2b1 indicating the positions where the hollow needles (not shown) are stuck are formed on the upper surface (top surface) of the rubber stopper T2b. However, when the hollow needle (not shown) is inserted into the needle sticking mark T2b1, the infusion solution contained in the infusion solution bag body T1 is discharged from the spout body T2a, so that the infusion solution bag T is used. It will be.

  Then, as shown in FIG. 3A, the protective seal 1 is attached to the upper surface (top surface) side of the spout T2 of the infusion bag T as described above. More specifically, since the rubber plug T2b is pierced by the hollow needle (not shown) as described above, the rubber plug T2b is contaminated by the adhesive of the adhesive layer 13 and / or the adhesive layer 23 of the protective seal 1. 3B, the non-adhesive layer 14 of the protective seal main body 10 is brought into contact with the upper surface (top surface) of the rubber stopper T2b so as not to be covered. The diameter of the non-adhesive layer 14 of the protective seal body 10 is larger than the diameter of the rubber stopper T2b.

  Next, from the state shown in FIG. 3B, the protective seal body 10 and the grip 20 are moved in the direction shown by the arrow P2 so that the protective seal body 10 and the grip 20 cover the spigot body T2a. As a result, as shown in FIG. 4A, the protective seal 1 is attached to the upper surface (top surface) side of the plug T2 of the infusion bag T.

  Next, when the protective seal 1 (protective seal body 10) attached to the upper surface (top surface) side of the mouth plug T2 of the infusion bag T is peeled off, as shown in FIG. The grip portion 20 is gripped by using, and the grip portion 20 is moved in the arrow P3 direction. At this time, the non-adhesive layer 24 is formed on the entire grip 20 so that the finger H of the user is not contaminated by the adhesive of the adhesive layer 23 of the grip 20. As a result, it is possible to reduce a situation in which the adhesive agent attached to the user's finger H adheres to the rubber stopper T2b and thus contaminates the rubber stopper T2b.

  Then, when the gripping portion 20 gripped by the user's finger H is moved in the direction of the arrow P3 shown in FIG. 4B, the pair of gripping portions 20 is moved as shown in FIG. 4C. A part 10B of the protective seal body 10 is fractured from the protective seal body 10 along the first perforation line 10d1 and finally along the second perforation line 10d2 as shown in FIG. 4 (d). As a result, a part 10B of the protective seal body 10 is broken from the protective seal body 10. As a result, as shown in FIG. 4D, the upper surface (top surface) of the rubber stopper T2b is completely exposed to the outside, so that the hollow needle (not shown) can be pierced into the needle puncturing mark T2b1. Will be possible.

  Then, as described above, when the protective seal body 10 attached to the upper surface (top surface) side of the mouth plug T2 of the infusion solution T is peeled off using the grip portion 20, it is formed on the protective seal body 10. Since the part 10B of the protective seal body 10 is broken along the perforations 10d, the trace of the protective seal body 10 once peeled remains.

  Further, as shown in FIG. 5 (a), from the state in which the protective seal 1 is attached to the upper surface (top surface) side of the mouth plug T 2 of the infusion bag T, a malicious one can detect foreign matter in the infusion bag T. Even if the protective seal body 10 is peeled off from a place other than the grip portion 20 due to mixing, as shown in FIG. 5B, due to the slit-like slit 10b formed on the outer periphery 10a of the protective seal body 10, A part 10A of the protective seal body 10 will be broken. As a result, even if the user tries to use the infusion bag T maliciously, a trace of someone using the infusion bag T will remain.

  Therefore, according to the present embodiment described above, it is possible to easily determine whether or not the predetermined member (infusion bag T in the present embodiment) is used.

  The shapes and the like shown in the present embodiment are merely examples, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims. For example, a serial number may be added to the protective seal body 10 for management. Further, an arrow may be added to the grip portion 20 to indicate the direction of peeling.

  On the other hand, in the present embodiment, an example in which a slight gap S is formed between the pair of first perforation 10d1 and second perforation 10d2 and the non-adhesive layer 14 of the protective seal body 10 is shown. However, the gap S may be formed in close contact without forming.

  By the way, a slight gap S is formed between the pair of first perforation 10d1 and second perforation 10d2 and the non-adhesive layer 14 of the protective seal body 10 as shown in FIG. 4 (d). This is to prevent the protective seal body 10 from being covered (completely exposed to the outside) on the upper surface (top surface) of the rubber stopper T2b. This makes it possible to prevent the protective seal body 10 from getting in the way when the hollow needle (not shown) is stuck in the needle stick mark T2b1. Therefore, even if the protective seal main body 10 covers the upper surface (top surface) of the rubber stopper T2b to some extent, but the protective seal main body 10 does not cover the needle stick mark T2b1, a pair of the first perforated line 10d1 and the second perforated line The small gap S may not be formed between 10d2 and the non-adhesive layer 14 of the protective seal body 10 and may be in close contact.

  However, it is preferable to form a slight gap S between the pair of first perforation 10d1 and second perforation 10d2 and the non-adhesive layer 14 of the protective seal body 10. When a pair of the first perforation 10d1 and the second perforation 10d2 and the non-adhesive layer 14 of the protective seal body 10 are brought into close contact with each other, when the part 10B of the protective seal body 10 is broken along the perforation 10d, Since it will be ruptured across the adhesive layer 13 and the non-adhesive layer 14 of the protective seal body 10, the shear resistance changes, so that the part 10B of the protective seal body 10 can be accurately formed along the perforations 10d ( This is because there is a high possibility that it cannot be broken (cleanly). Therefore, it is preferable to form a slight gap S between the pair of the first perforation 10d1 and the second perforation 10d2 and the non-adhesive layer 14 of the protective seal body 10.

  Further, in the present embodiment, an example in which the perforation 10d is formed in the protective seal body 10 has been shown, but the present invention is not limited to this, and any part of the protective seal body 10 may be broken as long as it can be broken. For example, the slit may be formed only between the protective seal body 10 and the grip portion 20.

  Further, in the present embodiment, an example in which the non-adhesive layer 14 and the non-adhesive layer 24 of the grip portion 20 are formed in the central portion of the protective seal main body 10 has been shown, but the present invention is not limited to this, and the protective seal main body is broken. A non-adhesive layer may be provided over the entire area or the almost entire area of the part 10B of 10 and the entire area or the almost entire area of the grip portion 20. That is, the non-adhesive layer 14 of the protective seal body 10 and the non-adhesive layer 24 of the grip portion 20 may be communicated with each other to form the non-adhesive layer.

  Further, in the present embodiment, an example in which the protective seal 1 is attached to the infusion bag T has been shown, but the present invention is not limited to this, and it may be attached to any place. For example, the protective seal 1 may be attached to the sealing part of a container that stores chemicals such as liquids and solids, and when the factory is visited, the security attached to the camera attached to the mobile phone, laptop computer, etc. The protective seal 1 may be attached as a seal.
