Description

[Technical Field]

[0001] The present invention relates to a label that is attached to, for example, the barrel of a medical syringe. [Background technology]

[0002] Conventionally, there are labels that are affixed to the surface of an object to which they are to be affixed, such as the barrel of a medical syringe or an enteral nutrition bag. As shown in Figure 9 of JP 2021-143002 A (Patent Document 1), for example, the label is affixed to the object to display various information on the surface of the object, such as the composition of the contents and a scale indicating the remaining amount of the contents. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-143002 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, labels can be attached manually, but they are often automatically attached to objects such as syringes using a label attachment device such as that described in Patent Document 1. That is, in Patent Document 1, a cylindrical holder presses a vacuum-adsorbed label onto the outer circumferential surface of the syringe barrel with the adhesive surface facing outward, thereby attaching the label to the barrel.

[0005] However, labels are generally made of thin, soft sheets and are attached with adhesives or the like, which can lead to air getting trapped between the label and the surface of the object to which it is attached, or to wrinkles. This is particularly true when the surface of the object to which it is attached is curved, such as the barrel of a syringe or an enteral nutrition bag. Furthermore, when labels are applied automatically, it is not possible to make corrections during application, which can lead to larger wrinkles.

[0006] The problem to be solved by the present invention is to provide a label having a novel structure that can effectively prevent adhesion defects such as partial lifting and wrinkles due to residual air with a simple structure. [Means for solving the problem]

[0007] The following describes preferred embodiments for understanding the present invention, but the embodiments described below are merely examples and may be appropriately combined with one another. Multiple components described in each embodiment may be recognized and employed independently to the greatest extent possible, and may also be appropriately combined with any of the components described in other embodiments. Accordingly, the present invention is not limited to the embodiments described below, and various other embodiments may be realized.

[0008] The first aspect is a label to be stuck to the surface of an object to be stuck, and has a sticking aid hole formed in a non-cutting area that is not to be cut and penetrates through in the thickness direction.

[0009] With a label constructed according to this embodiment, air between the overlapping surfaces of the label and the surface of the object to be affixed can be easily expelled to the outside through the affixing auxiliary holes when the label is affixed, preventing the label from partially lifting due to residual air. In addition, the affixing auxiliary holes that penetrate the label are expected to improve the label's ability to conform to the surface shape of the object to be affixed, preventing the label from wrinkling when affixed.

[0010] The attachment aid holes are located in the non-cutting area where cutting is not planned, and are not subject to external cutting forces like perforations used to assist cutting, making them less likely to tear during application. While perforations for cutting require visibility to identify the cut location, attachment aid holes do not require visibility, and it is desirable for them to be inconspicuous, especially after application. Furthermore, attachment aid holes that do not contribute to cutting do not need to reach the edge of the label, allowing for greater freedom in their placement.

[0011] In a second aspect, in the label according to the first aspect, the attachment assist hole is a longitudinal notch.

[0012] With a label constructed according to this aspect, the attachment assist holes are longitudinal cutouts, which allow air to be discharged over a wider area to the outside, effectively preventing partial lifting, etc. Furthermore, the attachment assist holes are longitudinal cutouts, which improves the label's ability to conform to the surface shape of the object to which it is attached, more effectively preventing the label from wrinkling when attached.

[0013] Since the notch-shaped attachment aid hole is not easily noticeable on a label attached to an object to be attached, it is less likely to interfere with the information display function of the label and also reduces the risk of it being mistaken for damage to the object to be attached or the label.

[0014] In the third aspect, in the label described in the second aspect, a dividing portion is provided that divides the attachment auxiliary hole into multiple portions in the longitudinal direction, and the attachment auxiliary hole is formed in the form of intermittent perforations in the longitudinal direction.

[0015] With a label constructed according to this aspect, even if the attachment auxiliary hole is long overall, the division of the attachment auxiliary hole into multiple sections prevents the attachment auxiliary hole from opening too wide when the label is attached, for example. This makes it possible to prevent air bubbles between the attachment surfaces and wrinkles in the label by the long attachment auxiliary hole, while ensuring stable, appropriate label attachment.

[0016] In a fourth aspect, the label according to any one of the first to third aspects is made of synthetic resin.

[0017] With a label constructed according to this aspect, even if the label is made of a synthetic resin with low breathability, the attachment aid holes can prevent air from remaining between the attachment surfaces. Note that the label of this aspect may have a composite structure in which multiple layers are superimposed, at least one of which is made of a synthetic resin with low breathability, and may be constructed, for example, to include a paper layer as well as a layer made of a highly breathable resin fiber or porous resin.

[0018] In a fifth aspect, in the label described in any one of the first to fourth aspects, an information display section is partially provided, and the attachment assist hole is formed in an area outside the information display section.

[0019] A label having a structure according to this aspect can prevent the attachment aid hole from affecting the visibility of the information display portion.

[0020] In a sixth aspect, the label according to any one of the first to fifth aspects is formed into a cylindrical shape by being wrapped around and stuck to the cylindrical surface of the object to be stuck.

[0021] With a label constructed in accordance with this embodiment, when the label is wrapped around the cylindrical surface of the object to be affixed to form a cylindrical shape, even in cases where air is more likely to remain between the adhesive surfaces, the adhesive auxiliary holes can effectively vent the air between the adhesive surfaces to the outside, preventing air accumulation and wrinkles and achieving a good adhesive condition.

[0022] A seventh aspect is the label according to any one of the first to sixth aspects, wherein the object to which the label is to be attached is a medical product.

[0023] In busy medical settings, labels affixed to medical products must be highly resistant to lifting, wrinkling, and other problems in order to make it easy to recognize from the appearance of the label that a medical product is an unused, clean product. Furthermore, the information displayed on the label is extremely important for medical products, and the adhesive strength of the labeling adhesive is often stronger than that of ordinary beverage bottles, making the label more difficult to peel off. This makes air pockets and wrinkles more likely to occur during label affixing, and these are difficult to eliminate. Therefore, the label according to the present invention, which can prevent lifting, wrinkling, and other problems by using the attachment aid holes as shown in this embodiment, is particularly suitable for use on medical products.

[0024] In an eighth aspect, in the label according to the seventh aspect, the object to which the label is to be attached is the barrel portion of a medical syringe.

[0025] Because medical syringes are used to inject liquid contents into a patient's body or puncture a patient's blood vessels, cleanliness tends to be particularly important, and there is a strong tendency to avoid defects in appearance such as label lifting or wrinkles, but because the outer peripheral surface of the barrel, which is the surface to which the label is attached, is cylindrical, label lifting, wrinkles, etc. Therefore, by applying the present invention to the label attached to a medical syringe to prevent label lifting, wrinkles, etc., it is possible to prevent the misconception that the medical syringe is not clean, which is caused by label lifting, wrinkles, etc.

[0026] The ninth aspect is a method for adhering a label to an object, in which a label having an auxiliary attachment hole penetrating through the thickness direction formed in a position biased to one side is used, and the label is adhered to the surface of the object from the side opposite to the side to which the auxiliary attachment hole is biased.

[0027] According to the label application method of this aspect, when the label is applied so that the adhesive surface gradually increases from one side to the other, the application auxiliary holes are formed closer to the application end than to the center in the application direction, so that the application auxiliary holes are located at the application end of the label, where lifting, wrinkling, etc. are particularly likely to occur, and this more effectively prevents the label from lifting, wrinkling, etc. In this aspect, application auxiliary holes may also be formed at the application start end in the application direction, but in consideration of appearance and workability, it is desirable that the application auxiliary holes be formed only at the application end in the application direction. [Effects of the Invention]

[0028] According to the present invention, in a label to be attached to an attachment object such as a medical syringe, adhesion defects such as partial lifting or wrinkles due to air remaining between the attachment surfaces can be effectively prevented with a simple structure.

DETAILED DESCRIPTION OF THE INVENTION

[0030] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0031] FIG. 1 shows a label 10 according to a first embodiment of the present invention. The label 10 is affixed to the surface of the barrel 32 of a medical syringe 30 (described below) for the purpose of displaying information on the surface of the barrel 32. In the following description, the front-to-rear direction generally refers to the up-and-down direction in FIG. 1, and the left-to-right direction generally refers to the left-to-right direction in FIG. 1. Furthermore, the front of the label 10 refers to the lower side in FIG. 1, which is the side where the label starts to be attached to the medical syringe 30, and the rear of the label 10 refers to the upper side in FIG. 1, which is the side where the label finishes being attached to the medical syringe 30.

[0032] The label 10 is shaped as a rectangular sheet with rounded corners overall. The label 10 may be made of paper, thin metal film, or the like, but is preferably made of a resin sheet. The label 10 is preferably made of synthetic resin, such as polypropylene, polyester, or modified polyolefin. The label 10 may also have a composite structure consisting of multiple layers combining a resin sheet, paper, thin metal film, or the like, with at least one layer preferably being made of a synthetic resin with low breathability. The synthetic resin label 10 can also be made of synthetic paper, such as synthetic pulp paper, spunbond paper, or synthetic film paper.

[0033] The label 10 may be opaque, but is preferably transparent or semi-transparent so that the liquid contained in the medical syringe 30 (described later) can be seen through the label 10. Note that the information display section 12 (described later) is partially opaque because various pieces of information are printed on it.

[0034] An adhesive layer is provided on the back surface of label 10. The adhesive layer is formed from various known adhesives, such as polyacrylic esters, natural or synthetic rubbers, and polyvinyl ethers. A release paper is superimposed on the back surface of label 10, protecting the adhesive layer and preventing dust from adhering to the adhesive layer. The release paper or film can be easily peeled off from the adhesive layer while maintaining the adhesiveness of the adhesive layer. As is conventionally known, the release paper is prepared by applying a release agent such as methylhydrogen polysiloxane or chromium stearate chloride to the surface of dense paper such as glassine paper or parchment paper, or laminated white paper, and then heat-curing the applied release agent.

[0035] An information display section 12 is provided on the surface of the label 10. The information display section 12 displays information such as the type and amount of the liquid (content liquid) contained in the medical syringe 30, the type of medical syringe 30, instructions for use of the content liquid and precautions regarding how to use the medical syringe 30, the name of the manufacturer of the medical syringe 30 and the content liquid, the manufacturer's address and contact information, expiration dates of the medical syringe 30 and the content liquid, the serial number of the medical syringe 30, a barcode or QR code (registered trademark) for managing the medical syringe 30, and a scale indicating the amount of the content liquid in the medical syringe 30. Note that the information displayed on the information display section 12 is not limited to the exemplified information, and other information may be displayed without displaying the exemplified information. Furthermore, it is not necessary for all of the exemplified various information to be displayed on the information display section 12, and appropriate information may be selected and displayed.

[0036] More specifically, for example, the information display unit 12 of this embodiment includes a scale 14 for grasping the amount of liquid contained in the medical syringe 30 (described later). The scale 14 is provided in pairs on both sides spaced apart from each other in the front-to-rear direction.

[0037] An entry section 16 is provided between the pair of scales 14, 14 on the information display section 12. The entry section 16 is, for example, a rectangular area printed in a light color such as white, and is a blank space where, for example, medical personnel can write notes with an oil-based pen or the like when using the device.

[0038] The information display section 12 is provided partially on the surface of the label 10. In this embodiment, the information display section 12 is located in the middle of the label 10 in the front-to-rear direction and does not reach the ends in the front-to-rear direction. As a result, non-printed areas 22 outside the information display section 12 are provided at both the front and rear ends of the label 10. Note that, although the information display section 12 and the non-printed areas 22, 22 in this embodiment are each provided over the entire length of the label 10 in the left and right directions, they may also be provided partially in the left and right directions of the label 10, for example.

[0039] An attachment auxiliary hole 24 is formed in the non-printing area 22 on the rear side of the label 10. The attachment auxiliary hole 24 is a hole that penetrates the label 10 in the thickness direction and is a longitudinal cut that extends in the left-right direction. The attachment auxiliary hole 24 is positioned offset to the right in the left-right direction of the label 10, and extends linearly from approximately the center of the label 10 to the right.

[0040] The attachment auxiliary hole 24 of this embodiment is divided into a plurality of parts in the left-right direction by dividing portions 26. The dividing portions 26 are provided continuously across both the front and rear of the attachment auxiliary hole 24, and one dividing hole 28 is formed on each of the left and right sides of the dividing portion 26. In this embodiment, eleven dividing portions 26, 26..., 26 are provided, and the attachment auxiliary hole 24 is divided into twelve dividing holes 28, 28..., 28. By providing a plurality of dividing portions 26 in this way, the attachment auxiliary hole 24 of this embodiment has a perforated shape that is provided discontinuously in the left-right direction.

[0041] The attachment assist hole 24 is not a cut to assist in cutting the label 10, but is provided in a non-cut area of ​​the label 10 where cutting is not planned. The label 10 of this embodiment has no parts to be cut, and the entire label 10 is a non-cut area. Therefore, the attachment assist hole 24 to be located in the non-cut area can be formed in any position on the label 10, but in this embodiment it is formed in the non-print area 22 outside the information display section 12 as described above.

[0042] In this embodiment, the attachment auxiliary hole 24 is formed after the information display section 12 is formed by means of printing or the like. Because the attachment auxiliary hole 24 is formed in the non-printing area 22 outside the information display section 12, even if the attachment auxiliary hole 24 is formed with various information already printed on the information display section 12, the formation of the attachment auxiliary hole 24 does not affect the printing of the information display section 12. Note that the attachment auxiliary hole 24 may be formed before the information display section 12 is formed, for example, which avoids problems such as the attachment auxiliary hole 24 affecting the printing of the information display section 12 or the attachment auxiliary hole 24 opening when the information display section 12 is printed.

[0043] As shown in FIGS. 2 and 3 , such a label 10 is attached to a medical syringe 30 as a target for attachment. The medical syringe 30 is a medical product and includes a cylindrical barrel portion 32 that contains a liquid (content liquid) such as a medicinal solution or blood, and a piston portion 34 that is inserted into the barrel portion 32 from the base end and moves toward the tip end to push the content liquid toward the tip end. The medical syringe 30 of this embodiment is a prefilled syringe that is provided with a predetermined liquid already contained therein. However, the medical syringe to which the label 10 is attached may also be an empty syringe that is filled with a medicinal solution from an ampoule before use or that is inserted into a blood vessel to collect blood. The liquid contained in the medical syringe 30 is not particularly limited and may be any liquid, such as a medicinal solution. The barrel portion 32 of the medical syringe 30 of this embodiment is transparent or translucent, allowing the content liquid to be visible from the outside.

[0044] The medical syringe 30 is subjected to a sterilization process. The sterilization process may be, for example, high-pressure steam sterilization, but steam sterilization using hydrogen peroxide is preferable. Therefore, the medical syringe 30 is made of a material that is corrosion-resistant and heat-resistant and can be subjected to steam sterilization. Note that steam sterilization of the medical syringe 30 is preferably performed before the label 10 is attached.

[0045] As shown in FIGS. 2 and 3 , the label 10 is wrapped around and attached to the barrel portion 32 of the medical syringe 30, forming a cylindrical shape when attached to the barrel portion 32. That is, the label 10 is attached by peeling off the release paper to expose the adhesive layer and then superimposing the back surface of the label 10 on the surface of the barrel portion 32. The method of attaching the label 10 is not particularly limited. However, in this embodiment, since the outer peripheral surface of the barrel portion 32, which is the surface to be attached, is a cylindrical surface, the entire label 10 is not attached at once. Rather, the label 10 is attached so that the attachment area gradually increases from the front end, which is the attachment start end of the label 10, to the rear end, which is the attachment end. Specifically, for example, the label 10 may be attached manually, or it may be attached by a roller-like device, such as that illustrated in JP 2021-143002 A, so that the label 10 is wrapped around the outer peripheral surface of the barrel portion 32 from the front end to the rear end. Alternatively, for example, the barrel portion 32 of the medical syringe 30 can be rotated while being pressed against the back surface of the label 10, and the label 10 can be attached by wrapping it around the outer circumferential surface of the barrel portion 32. Note that in FIG. 1, an annular frame portion 36 that remains on the release paper side is provided around the periphery of the label 10 attached to the barrel portion 32, but in FIGS. 2 and 3, the label 10 without the frame portion 36 is attached to the barrel portion 32. However, the frame portion 36 does not have to be provided on the label 10 before attachment.

[0046] The attachment auxiliary hole 24 is formed in the non-printing area 22 located on the attachment end side of the label 10 relative to the barrel portion 32. In other words, it is desirable that the label 10 be attached to the barrel portion 32 from the side opposite to the side on which the attachment auxiliary hole 24 is formed. It is desirable that the attachment auxiliary hole 24 be located on the rear side, that is, the attachment end side, of the label 10 relative to the center in the front-to-rear direction, and more preferably, within a range of 1 / 4 of the total front-to-rear length of the label 10 from the attachment end.

[0047] The attachment auxiliary hole 24 extends longitudinally in a direction intersecting the front-rear direction, which is the direction in which the label 10 is attached to the barrel portion 32. In this embodiment, the attachment auxiliary hole 24 extends in the left-right direction, approximately perpendicular to the front-rear direction.

[0048] When the label 10 is attached to the barrel portion 32 of the medical syringe 30, as can be seen from Figure 2, the amount of liquid contained in the medical syringe 30 can be easily determined visually by checking the scale 14 on the information display portion 12.

[0049] 3, both circumferential ends of the label 10 wrapped around the barrel portion 32 of the medical syringe 30 are overlapped with each other. As a result, when the label 10 is attached to the barrel portion 32, it has a cylindrical shape that corresponds to the outer peripheral surface of the barrel portion 32. Note that the both circumferential ends of the label 10 wrapped around the barrel portion 32 may be separated from each other in the circumferential direction.

[0050] While it is desirable for the label 10 and the outer peripheral surface of the barrel portion 32 to be in close contact with each other without any gaps, conventional labels sometimes experience air remaining between the label and the outer peripheral surface of the barrel portion 32 during application, resulting in partial lifting or wrinkles. This problem is particularly problematic when using a device that applies labels by pressing them against the outer peripheral surface of the barrel portion 32 with a roller. For example, if a label is incorrectly applied to the surface of the barrel portion 32 closer to the application end than the application position of the roller, air may remain between the application surface of the label and the barrel portion 32 between the application position of the roller and the incorrectly applied application end. This residual air may cause partial lifting or wrinkles of the label. Misplaced label application is particularly likely to occur near the end, where the label's holding area is smaller and it is difficult to obtain sufficient label holding force. FIG. 4 shows an example in which wrinkles A occur when a conventional label is attached to the outer peripheral surface of the barrel portion 32 of a medical syringe 30.

[0051] Here, the label 10 of this embodiment is provided with the attachment auxiliary hole 24 that penetrates in the thickness direction, and therefore air between the overlapping surfaces of the label 10 and the barrel portion 32 is discharged to the outside through the attachment auxiliary hole 24. This prevents partial lifting of the label 10 due to air remaining between the attachment surfaces.

[0052] 3, in this embodiment, the label 10 is attached to the barrel portion 32 from the front side, which is farthest from the attachment auxiliary hole 24, toward the rear side. In other words, the attachment auxiliary hole 24 is located on the attachment end side of the label 10. Therefore, as the attachment of the label 10 progresses, the air between the label 10 and the barrel portion 32 is pushed toward the attachment auxiliary hole 24 by the roller, and the air is discharged to the outside through the attachment auxiliary hole 24, more effectively preventing air from remaining between the attachment surfaces of the label 10 and the barrel portion 32.

[0053] Furthermore, residual air between the application surfaces of the label 10 and the barrel portion 32 is likely to occur between the application position by the roller and the application end side, for example, when the label 10 is unintentionally applied to the barrel portion 32 closer to the application end than the application position by the roller. Therefore, at least a portion of the residual air is likely to be located near the application end side. Therefore, if the application auxiliary hole 24 is formed in the non-printed area 22 on the application end side, even if air enters between the application surfaces as described above, the air will be discharged as quickly and stably as possible through the application auxiliary hole 24, preventing lifting, wrinkles, and the like caused by residual air.

[0054] Because the label develops a three-dimensional curved shape at the location where air bubbles form between the application surfaces due to residual air, if the area where the air bubbles form is sealed as in conventional labels, the label may stretch or shift when the roller presses the area where the air bubbles form. For example, air bubbles may grow larger as application progresses. If the label is forcibly pressed by the roller in a stretched and / or shifted state due to the air bubbles, the expanded area due to the air bubbles may be crushed, causing the labels to overlap, resulting in wrinkles as shown in FIG. 4. Furthermore, once wrinkles form, even if air escapes from the application end of the label as application progresses, the wrinkles remain and remain. Therefore, in the label 10 of this embodiment, by forming the application auxiliary hole 24 at the application end where air bubbles are likely to form, the application auxiliary hole 24 can prevent the area where the air bubbles form from being sealed, even if an air bubble, at least a portion of which is located at the application end, as described above, is formed. Therefore, even if the portion where the air bubble is formed is pressed by a roller, the label 10 is less likely to be stretched, deformed, or shifted, and wrinkles are prevented from forming.

[0055] In addition, wrinkles in the label 10 are prevented by preventing air from remaining between the label 10 and the barrel portion 32 and by making it easier for the label 10 to deform in the area where the attachment assist hole 24 is formed.

[0056] In this way, partial lifting or wrinkling of label 10 is prevented, and label 10 can be stably attached in an appropriate state with the entire label in close contact with the outer circumferential surface of barrel portion 32. This prevents problems such as users feeling uneasy about the safety of medical syringe 30 or its contents due to appearance defects caused by poor attachment of label 10.

[0057] In this embodiment, it is conceivable that the medical syringe 30 before the label 10 is affixed thereto may be slightly deformed by the heat generated during steam sterilization. In particular, the cylindrical barrel portion 32 is likely to be deformed by heating and cooling, resulting in the formation of minute irregularities on its surface, and it is therefore anticipated that the label 10 affixed to the barrel portion 32 may be more likely to lift or wrinkle. Even in cases where the barrel portion 32 is deformed by the heat generated during steam sterilization, the formation of the attachment assist hole 24 in the label 10 allows the label 10 to be attached while accurately conforming to the outer peripheral surface of the barrel portion 32, which is the surface to be affixed, thereby preventing partial lifting, wrinkles, or the like of the label 10.

[0058] It has also been confirmed through prototypes that defects such as partial lifting and wrinkling can be prevented in labels 10 equipped with attachment assist holes 24. That is, when labels 10 equipped with attachment assist holes 24 according to the present invention were actually attached to 195 medical syringes 30, no adhesion defects such as lifting or wrinkling occurred.

[0059] Although the embodiments of the present invention have been described in detail above, the present invention is not limited by those specific descriptions. For example, the attachment auxiliary hole does not necessarily have to extend in the left-right direction like attachment auxiliary hole 24 in the first embodiment, but may extend in the front-to-rear direction like attachment auxiliary hole 42 of label 40 shown in Figure 5. Furthermore, like attachment auxiliary hole 52 of label 50 shown in Figure 6, it may be provided so as to extend at an angle to either the left-to-right direction or the front-to-rear direction, rather than extending parallel or perpendicular to either the left-to-right direction or the front-to-rear direction. In other words, when a longitudinal attachment auxiliary hole is formed in a label, the longitudinal direction of the attachment auxiliary hole does not necessarily have to be perpendicular to the label attachment direction (the direction in which the attachment start and end points are located) as in the first embodiment. According to the labels 40, 50 shown in Figures 5 and 6, when attached to the medical syringe 30, the longitudinal direction of the attachment auxiliary holes 42, 52 does not coincide with the axial direction of the barrel portion 32, which makes it easier to prevent the attachment auxiliary holes 42, 52 from being mistaken for cracks, etc., in the barrel portion 32, for example.

[0060] The number of attachment auxiliary holes 24 is not particularly limited. Specifically, for example, as in the label 60 shown in FIG. 7, two attachment auxiliary holes 24, 24 may be formed at a predetermined distance from each other in the longitudinal direction. Alternatively, as in the label 70 shown in FIG. 8, attachment auxiliary holes 24 may be formed in both the front non-printed region 22 and the rear non-printed region 22. Alternatively, multiple attachment auxiliary holes 24 may be arranged in parallel at a predetermined distance from each other in the width direction in the front or rear non-printed region 22. Providing multiple attachment auxiliary holes 24 in this manner allows for greater flexibility in their placement, improving air evacuation efficiency and deformation compliance, and more effectively preventing partial lifting, wrinkling, and the like of the labels 60, 70. Note that when multiple attachment auxiliary holes are provided, the placement of the multiple attachment auxiliary holes is not particularly limited, as long as each attachment auxiliary hole is located in a non-cutting region that is not intended to be cut.

[0061] The attachment aid holes are preferably longitudinal cuts as shown in the first embodiment from the viewpoints of being less noticeable in appearance, allowing air to be exhausted over a wide area, and improving conformability to deformation, but they may also be slits that are opened in advance with a certain width, circular holes, etc. Also, they may be formed by dispersing a large number of very fine, dot-like holes.

[0062] In the first embodiment, an example was shown in which the attachment auxiliary hole 24 was formed in the non-printed region 22 outside the information display section 12, but the attachment auxiliary hole may also be formed in the information display section. For example, it is also possible to form the attachment auxiliary hole in the information display section in cases in which the attachment auxiliary hole does not affect the formation of the information display section, such as when the attachment auxiliary hole is formed after the information display section is printed, when the attachment auxiliary hole is an extremely fine hole, or when the information display means in the information display section is not printed.

[0063] The object to which the label is attached is not limited to the medical syringe 30 exemplified in the first embodiment. However, the object to which the label is attached is preferably one with a non-flat surface, which is prone to air residue during attachment, and is preferably a medical product that avoids cosmetic defects. Specific examples of medical products to which the label can be attached include a double-chamber bag that separately contains a powder formulation and a dissolving solution and mixes and dissolves them when used, an infusion bag that contains infusion fluids such as blood or medicinal solutions, and an enteral nutrition bag that contains nutrients administered via a gastrostomy. Furthermore, general plastic containers, glass bottles, metal cans, and other items other than medical products can also be used to attach the label of the present invention.
