Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a tamper-proof label that allows easy confirmation of the presence or absence of opening and prevents the contents from being tampered. More specifically, the present invention relates to a disposable syringe that is pre-filled with a chemical solution and used for one-time use. The present invention relates to a tamper-proof label suitable for use in, for example.
[0002]
[Prior art]
In recent years, disposable syringes for one-time use have been widely used in fields such as the medical field and medical research. Some of such disposable syringes are prefilled with a drug solution 12 in the syringe barrel 11 as shown in FIGS. In the syringe shown in the figure, the distal end opening 13 of the syringe barrel 11 is sealed with a rubber stopper 14, and in use, the rubber stopper 14 is removed and an injection needle is attached to the distal opening 13 for use. . Therefore, for example, the tip opening 13 is roughened so that the rubber plug 14 does not easily come off before use. When the rubber plug 14 is removed, the rubber plug 14 is twisted. It comes to remove.
[0003]
In such a disposable syringe, it is necessary to prevent the chemical liquid 12 from being tampered with, particularly in order to guarantee the sterility of the contents. Thus, it is conceivable to prevent tampering as follows.
[0004]
(1) For example, as shown in FIG. 6, the adhesive label 15 with the cutting 15a is wound around the periphery of the rubber stopper 14 and the periphery of the syringe barrel 11.
[0005]
(2) Disposable syringes are usually shipped and stored in plastic containers, so take measures to check whether the containers are open, not the syringes themselves. Take.
[0006]
(3) A heat-shrinkable film called a shrink film that shrinks by heat is used. For example, after the heat-shrinkable film is disposed around the rubber stopper 14 and the syringe barrel 11, the film is shrunk by applying heat. .
[0007]
[Problems to be solved by the invention]
Among the above methods, the method (1) is inconvenient in the following cases. That is, when the adhesive label 15 is wound, if the part of the cutting 15a is displaced and applied to the syringe barrel 11, the adhesive part on the cutting 15a part adheres and the effect of the cutting 15a is lost. Moreover, even if force is applied and forcibly separated, the adhesive remains in the syringe barrel 11 and is unsanitary.
[0008]
Next, in the method (2) above, since the disposable syringe filled with the drug solution 12 is required to display the name of the drug solution on the syringe itself, a label indicating the drug solution name is affixed to the syringe itself. Must. However, in some cases, for example, from the standpoint of concern about the patient's mental impact, the container may be opened in advance and the label may be peeled off before use, not just before use. In this case, if there is a period between the use of the label and the use, it is difficult for the method (2) to confirm whether or not tampering has occurred during use.
[0009]
The method (3) has the following restrictions. That is, when the chemical solution 12 that is weak against heat is filled, a heat shrinkable film that requires heating cannot be used in order to avoid adverse effects on the chemical solution 12. Furthermore, when using a heat-shrinkable film, there also arises a problem that a special device dedicated to the mounting is required.
[0010]
In addition, the use of a stretchable film such as a stretch film can be considered, but this has a problem that it is difficult to obtain a film that can be applied to a small diameter and has a certain degree of stretchability.
[0011]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a tamper-proof label that can be used for a disposable type syringe filled with a heat-sensitive chemical solution. .
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the tamper-proof label according to the invention of claim 1 is used for a syringe in which a tip opening of a syringe barrel is sealed with a rubber stopper, and one surface has adhesiveness, A tamper-proof label wound around the rubber plug and around the syringe barrel, the tamper-proof label being punched inside leaving the periphery and wound around the syringe , together with the left and right sides overlapping, passed the label portion bridged between the rubber stopper and the syringe barrel is adapted to only the left and right sides, and a part of the left and right sides, almost the same as viewed from the vertical direction the height position, the cutting from opposite sides is subjected, when removing the rubber plug in a state of being wound on the syringe, and characterized in that the cutting is adapted to be cut
[0013]
Preferably, the length of the tamper-proof label in the left-right direction is such that the left and right sides substantially overlap when wrapped around the rubber stopper and the syringe barrel.
[0014]
According to the above configuration, since the inside is a punched portion, when the tamper-proof label is wrapped around the rubber plug and the periphery of the syringe barrel, the rubber plug and the syringe barrel The label portion spanned between the left and right sides can be only left and right.
[0015]
Also, when removing the rubber plug, it is necessary to twist the rubber plug while twisting it to some extent. At this time, the tension acts on the left and right sides of the label along with the twisting operation. However, force is applied in either the left or right direction. By applying such a force, the cutting parts applied to the left and right sides are cut off. Therefore, it is easy to check whether the cutting parts are open or closed by checking whether or not the cutting parts are cut during use. It will be possible.
[0016]
Since the cutting is provided on both the left and right sides, even when the rubber plug is twisted in either the left or right direction, it is easily cut off at this cutting portion.
[0017]
Even if the rubber plug can be removed without cutting the cutting part, it is almost impossible to return it to the same state as before the rubber plug was removed. Easy to distinguish.
[0018]
In addition, such a label can be easily attached by a normal labeler or manual work, and therefore, unlike the case of using a heat-shrink film or the like, it does not require heating and is specially used for its installation. No special equipment is required.
[0019]
In addition, the length of the label in the left-right direction is such that the left and right sides overlap each other when wrapped around the rubber stopper and the syringe barrel. Even if the surface of the rubber stopper does not have adhesiveness, it is possible to secure the adhesion at both ends of the label and to wrap around the entire circumference of the rubber stopper and the syringe barrel, thus preventing tampering more reliably. Can be expected.
[0020]
The label shape of the present invention is not particularly limited, and a rectangular shape, a rhombus shape, an oval shape, a capsule shape, a circular shape, and other polygonal shapes can be considered. The punched portion does not necessarily match the external shape of the label, and the punched portion may be formed by punching into a shape different from the external shape.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
The following describes one embodiment of the present invention with reference to FIGS.
[0022]
FIG. 1 is a plan view showing a tamper-proof label 1 of the present embodiment. As shown in the figure, the tamper-proof label 1 has a substantially rectangular shape, and is a punched portion 2 punched inside leaving four sides (that is, surroundings), and the left side. Cutting 5 is applied to part of (left side) 3 and right side (right side) 4. The left and right cuttings 5 are provided at substantially the same height when viewed from the top and bottom, and the left and right sides (both left and right sides) 3 and 4 are cut from both sides.
[0023]
Moreover, the said label 1 has adhesiveness on one side like a normal adhesive label, The length L of the left-right direction is when it wraps around the syringe which uses this label 1 as a tamper-proof label. The length is set such that the left and right sides 3 and 4 substantially overlap each other (ie, when wrapped around the periphery of the rubber stopper and the periphery of the syringe barrel).
[0024]
A number of the tamper-proof labels 1 can be produced on a belt-like sheet 6 having a surface coated with silicon or the like, as shown in FIG. When they are wound around a syringe as a tamper-proof label, they can be easily wound mechanically using a normal labeler, and if sterility is ensured, they can also be wound manually. It is possible.
[0025]
The tamper-proof label 1 is, for example, as shown in FIG. 5, a syringe in which a syringe barrel 11 is prefilled with a drug solution 12 and the tip opening 13 of the syringe barrel 11 is sealed with a rubber stopper 14, It can be suitably used for a syringe or the like filled with a heat-sensitive chemical solution 12.
[0026]
FIGS. 3A to 3C are diagrams for explaining that the effect of preventing falsification is obtained when the tamper-proof label 1 is used for the syringe shown in FIG. That is, as shown in FIG. 3A, the tamper-proof label 1 is wound in advance around the periphery of the syringe, that is, the periphery of the rubber stopper 14 and the periphery of the syringe barrel 11. Since the label 1 wound in this way is a punched portion 2 in which the inside is punched, in the wound state, the label is stretched between the rubber stopper 14 and the syringe barrel 11. As shown in FIG. 3B, only the left and right sides 3 and 4 are present.
[0027]
Further, since the length L in the left-right direction of the label 1 is set to such a length that the left and right sides 3 and 4 substantially overlap when wound, as shown in FIG. In this state, the left side 3 and the right side 4 overlap. Further, since the left and right cuttings 5 are provided at substantially the same height as viewed from the top and bottom, as shown in FIG. , Will overlap each other.
[0028]
In the state where the label 1 is wound as described above, the disposable syringe is placed in a distribution process and stored until use.
[0029]
When trying to remove the rubber plug 14 that seals the tip opening 13 of the syringe, as shown in FIG. 3 (c), the rubber plug 14 must be removed while being twisted to some extent. With this twisting operation, tension is applied to the left and right sides 3 and 4 of the label 1, and a force is applied in either the left or right direction. As a result, the label 1 is cut at the part where the left and right cuttings 5 are made, and is cut up and down.
[0030]
Further, since the cutting 5 is provided on both the left and right sides 3 and 4, even when the rubber plug 14 is twisted in either the left or right direction, the portion to which the cutting 5 is applied is easily cut. The
[0031]
Therefore, by confirming whether or not the cutting portion 5 is cut at the time of use, the presence / absence of opening / closing can be easily confirmed, and a sure effect of preventing falsification can be expected.
[0032]
Even if the rubber plug 14 can be removed without cutting the cutting 5 portion, the inside of the label 1 is the punched portion 2, so that the label 1 is removed when the rubber plug 14 is removed. Therefore, after removing the rubber plug 14, it is almost impossible to return to the original state again.
[0033]
In addition, unlike the case where the heat-shrinkable film 1 is used, the tamper-proof label 1 does not require heating to be wrapped around the rubber stopper 14 and the syringe barrel 11, so that the heat-sensitive chemical solution 12 is Even when filled, there is an advantage that the stability of the contents is ensured.
[0034]
In the tamper-proof label 1, materials and the like are not particularly limited.
[0035]
Moreover, in this tamper-proof label 1, as shown in FIG. 1, the label shape is formed in a substantially rectangular shape, but the label shape of the present invention is not particularly limited to this. For example, as shown in FIGS. 4A to 4C, it may be formed as a diamond-shaped label 7, an elliptical label 8, or a capsule-shaped label 9, or a shape such as a circle or a polygon. It is good also as what is formed. The punched portion does not necessarily match the external shape of the label, and the punched portion may be formed by punching into a shape different from the external shape.
[0036]
【The invention's effect】
As described above, the tamper-proof label according to the invention of claim 1 is a rectangle, an ellipse, or other shapes, and is a punched portion in which the inside is punched leaving the periphery, and both left and right sides It is the structure by which cutting is given to a part of both sides.
[0037]
Therefore, by confirming whether or not the cutting portion is cut at the time of use, it is possible to easily confirm the presence / absence of opening and closing, and a reliable effect of preventing falsification can be expected. Furthermore, even when the label is wound, even if the cutting part is shifted to the syringe barrel side, the inside of the label is a punched part, so that it does not require much force for separation, and the part that remains in the syringe cylinder There is also an effect in use that it is only on both the left and right sides, and the mounting of the injection needle becomes easy.
[0038]
In addition, unlike the case of using heat-shrink film, etc., it does not require heating to wrap around the rubber stopper and syringe. The effect of ensuring is also produced.
