Description

  The present invention relates to a heat-shrinkable label and a container used for a liquid storage container such as an eye drop container.

  Conventionally, a relatively small liquid storage container such as an eye drop container made up of a container body and a cap part fastened to the container body outlet is heat-shrinkable across the cap part and the container body. It is common to coat with a film label. On this label, information such as a medicine name and content is printed on the surface of the region covering the container body, and the contents of the liquid storage container can be identified. This label can be used to fix the cap part and the container main body integrally, and to prevent foreign matters from entering the container from the outside, which is very useful in terms of hygiene.

  Generally, a label is formed in a sheet shape, wound around a peripheral side surface of a container, and a band-like bonding portion formed on one side end portion of this label is attached to the other side end portion. And is attached so as to be in close contact with the outer peripheral surface of the container body by heat shrinkage. In some cases, the label is formed as a cylindrical label in advance, and is externally fitted to the container and packaged by heat shrinkage.

  However, since the label is generally formed of a transparent or plain synthetic resin, it is difficult to determine the degree of thermal shrinkage at first glance, and it is difficult for the manufacturer to determine whether the shrinkage is good or bad.

  In addition, there are a plurality of types of drugs such as eye drops depending on the content of the substance, etc. However, due to the production efficiency of the manufacturer and the like, containers of the same form are often used when the same filling amount is used. In this case, only the label content display on the side of the container body is changed and shipped.

  When discriminating multiple eye drops, the user needs to check the contents by looking at the content display located on the side of the container body of the label that is packaging the container. When a plurality of containers are closely stored and only the upper surface of the cap portion can be seen, there is a problem that it is difficult to identify contents.

  The present invention has been made in view of the above problems, and can easily check the thermal shrinkage of the label, and further has a heat-shrinkable label having distinctiveness when viewed from the upper surface direction of the cap of the container, and An object is to provide a container packaged with the heat-shrinkable label.

Means for solving the problems / effects of the invention

In order to solve the above-mentioned problems, the heat-shrinkable label of the present invention substantially includes a cap part for packaging a container comprising a container body and a cap part that is detachably attached to an outlet of the container body. A heat-shrinkable label comprising a first region to cover and a second region to cover the container body,
The first region and the second region are connected to each other through a horizontal perforation,
The first region is provided with a belt-like colored layer along its upper edge,
The upper end of the first region is set taller than the upper end of the cap of the container;
When the heat-shrinkable label is packaged in a container by heat shrinkage, the colored layer is formed so that a belt-like annular colored layer is located at least at the peripheral edge of the top surface of the cap portion.

  According to the present invention, the colored layer is provided along the top surface periphery of the cap portion, and the colored layer is formed so as to include a part of the top surface. Thus, a band-like annular colored layer can be confirmed. For this reason, even if it fills with the container of the same form by making coloring of a colored layer differ by the difference in content etc. of a content, it can identify easily by the difference in the color of a colored layer.

  Also, when packaged by heat shrinkage, if the heat shrinkage is uniform, a band-shaped annular colored layer is formed along the top surface periphery of the cap part, and if the heat shrinkage is not uniform, the colored layer is distorted. The quality of the degree of thermal shrinkage can be automatically determined by, for example, optically checking the colored layer.

The heat-shrinkable label of the present invention is formed as a sheet-like heat-shrinkable film,
This heat shrink film is provided with a belt-like adhesive layer on one side edge,
It is wound around the peripheral side surface of the container, the adhesive layer adheres to the other side end of the heat shrink film, and heat shrinks to wrap the container. Thus, by forming it in a sheet shape, it becomes easy to perform printing for displaying the contents, and there is an effect that it is easy to form a perforation for opening the label.

  In addition, the colored layer may be formed on a part of the peripheral side surface of the cap portion, and thus the colored layer can be confirmed even when the side surface of the container is viewed from the side of the container.

  In addition, the colored layer can be formed so as to be located across the corner portion between the top surface of the cap portion and the peripheral side surface of the cap portion in a state where the cap portion is packaged. As a result, the annular colored layer is formed in a band shape along the peripheral edge of the top surface of the cap part so as to include a part of the top surface and a part of the peripheral side surface. Even when the side surface of the container is viewed from the side of the container, the annular colored layer can be confirmed.

  Further, an adhesive can be applied to the back surface of the second region so as to be fixed to the container body trunk. As a result, when the label is broken and the container is opened, the label for packaging the container body is fixed to the container body by the adhesive, so that only the label for packaging the cap can be removed.

  Further, the heat-shrinkable label of the present invention has a knob portion formed so as to be connected to a predetermined perforation line for opening the heat-shrinkable label packaging the container and project from the upper end portion of the first region. It can be formed to provide. Thus, when the label is opened, the perforation line formed in the first region with the knob portion can be broken and opened, and the label is easy to open.

  In addition, the colored layer can be formed so as to include the knob portion, thereby making it easy to understand the position of the knob portion and providing a large colored layer on the top surface of the cap portion, so that it can be identified when viewed from above the container. Is easier to do.

  Further, in the present invention, it can be formed as a container packaged with the heat-shrinkable label as described above, and the colored layer formed on the heat-shrinkable label is located on the top surface and the peripheral side surface of the cap part. A container having distinctiveness is obtained when viewed from above and from the side of the container.

  Moreover, the container of this invention has accommodated the pharmaceutical in the container main body. As a result, the stored medicine can be easily identified, and the misuse of the medicine by the user can be prevented.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a developed front view of a label 1 according to the present invention. The label 1 is made of a heat-shrinkable synthetic resin and is formed as a rectangular film or sheet. The label 1 includes an upper half first area 1A and a lower half second area 1B. The first area 1A and the second area 1B are connected to each other via a horizontal perforation line 7. Has been established.

  As the heat-shrinkable synthetic resin used in the present invention, a known resin usually used for packaging can be used, and examples thereof include films of polyethylene terephthalate, polypropylene, polyvinyl chloride, polyethylene and the like. be able to.

  In the first region 1A, a colored layer 2 colored in a strip shape is formed at the upper end. The ink used for this colored layer 2 has a heat-shrinkable film and has a necessary resistance, and a commonly used ink such as an ultraviolet curable ink is used. can do.

  As shown in FIG. 2, a strip-shaped adhesive layer 8 is formed on the back surface of the label 1. In addition, although not shown on the front surface or the back surface of the second region 1B, for example, the chemical name, product name, manufacturer, vendor, container / label material, expiration date, serial number, etc. of the stored chemical solution are legally displayed. Can be provided as appropriate, and an adhesive 9 (for example, a known adhesive such as a heat-sensitive adhesive or a pressure-sensitive adhesive) is applied to an appropriate portion on the back surface of the second region 1B. Yes. Since the label 1 is fixed to the container body by the adhesive 9, the label can be left on the container even after the label 1 is broken and opened.

  The label 1 of the present invention is wound around and attached to the peripheral side surface of the eye drop container 3 and packaged so as to be in close contact with the shape of the eye drop container 3 by heat shrinkage. That is, as shown in FIG. 3, after forming the printed layer as described above, the label 1 starts to be wound from one end around the eye drop container 3 filled with the contents, and goes around the label to label the adhesive layer 8. 1 is overlapped with the other side end portion, and the overlapping portions of both end sides are bonded with an adhesive, a solvent, heat fusion or the like. Then, the label 1 is attached to the eye drop container 3 by heat shrinking by a known means such as a steam tunnel having a heat shrink temperature or a hot air tunnel. At this time, the label 1 externally fitted to the eye drop container 3 is heat-shrinked at a heat shrinkage rate of 45% or more in the vertical direction and 10% or less in the horizontal direction at 100 ° C., for example. As shown in FIG. When the eye drop container 3 is packaged in this way, the first region 1A covers the cap portion 4 and the second region 1B covers the container body 5.

  FIG. 6 is a cross-sectional view of the cap portion 4 of the eye drop container 3 in which the label 1 is packaged. When the label 1 wraps the eye drop container 3, the colored layer 2 formed on the upper end portion of the first region 1A is positioned along the periphery of the top surface 4a of the cap portion 4 and includes the periphery of the top surface 4a. The colored layer 2a is formed on 4a, and the colored layer 2b is formed on the side surface 4b.

  In addition, in the above description, although the label 1 formed as a sheet-like heat-shrink film was demonstrated, the label previously formed in the cylinder shape can also be used. That is, the long cylindrical film is cut so as to be taller than the upper end portion of the eye drop container 3 to obtain a cylindrical label 10 having a predetermined length as shown in FIG. Then, the label 10 is opened, and the label 10 is inserted into the eye drop container 3 to be thermally contracted and packaged.

  The label 1 described above is shipped to a pharmacy or hospital in a state where the eye drop container 3 is packaged by heat shrinkage as described above. At this time, if packaging is performed by heat shrinkage, if the heat shrinkage is not uniform due to, for example, insufficient heating due to the heating time or the heating temperature, the close contact with the eye drop container 3 may be insufficient. For this reason, a manufacturer that fills the eye drop container 3 with contents such as eye drops and wraps with the label 1 needs to confirm whether the label 1 is uniformly heat-shrinked and wraps the eye drop container 3. There is. At this time, since a normal packaging label is formed of a transparent synthetic resin, it is difficult to understand the degree of thermal shrinkage at first glance. However, according to the label 1 of the present invention, when the heat shrinkage is uniform when packaged by heat shrinkage, the colored layer 2 is formed along the periphery of the top surface 4a of the cap part 4 as shown in the plan view of FIG. Is formed in an annular shape, and if the heat shrinkage is not uniform, the colored layer 2 is distorted. Therefore, the quality of the heat shrinkage can be determined by checking the colored layer 2 from the upper surface direction of the cap portion 4. .

  As a means for inspecting the degree of thermal shrinkage, an image of the eye drop container 3 packaged with the label 1 is imaged using a CCD camera installed on a transport line, and the image is displayed on a monitor for confirmation. In the conventional examination, the CCD camera is arranged at a position where the eye drop container 3 is viewed from the side, and the eye drop container 3 is temporarily stopped on the transport line and simultaneously rotated at that position. The peripheral side was imaged and inspected. At this time, in order to image the peripheral side surface of the eye drop container 3, it is necessary to release the shutter several times, and it is necessary to check the plurality of monitor images. . However, according to the label 1 of the present invention, the CCD camera is placed at a position where the top surface 4a is viewed from directly above the eye drop container 3, and an image is taken by the CCD camera while the eye drop container 3 is moving. Then, only the captured image of the top surface 4a of the cap unit 4 is confirmed. For example, whether or not the colored layer 2 is formed in an annular shape along the periphery of the top surface 4a of the cap portion 4 depending on the thickness of the band of the colored layer 2a, and the color of the colored layer 2 are inspected, and even one defect is present. If there is, it is discharged out of the system. Thus, since only the image of the top surface 4a of the cap part 4 is confirmed, the quality of the thermal contraction of the label 1 can be determined, so that the inspection can be efficiently performed.

  Next, at medical sites such as pharmacies and hospitals, pharmacists, doctors, etc. prepare to deliver eye drops to patients based on drug prescriptions and the like. There are multiple types of drugs, such as eye drops, depending on the content of the substance, etc. For reasons such as production efficiency of the manufacturer, the container body 5 side should be used by using the same type of container when filling the same amount. Shipped with only changing the label content display. For this reason, since the form of the container is the same for the user side, it is difficult to identify the contents at first glance. In particular, if the type of eye drops is the same and only the content is different, the drug name is the same, but only the content display is described differently, so even if the label content display on the side of the container body 5 is displayed. Even if confirmed, there is a risk of confusion. However, according to the label 1 of the present invention, even for the same drug name, for example, when the content is 0.05%, the color of the colored layer 2 of the label 1 is red, and when the content is 1%, the color is colored. By changing the color of the colored layer 2 by changing the color of the layer 2 to green or the like, the contents can be easily discriminated.

  Further, as shown in FIG. 6, the colored layer 2 includes the periphery of the top surface 4a of the cap portion 4, and the colored layer 2a is located on the top surface 4a and the colored layer 2b is located on the side surface 4b. 4. When viewed from above, it can be confirmed by the colored layer 2a, and when viewed from the side of the eye drop container 3, it can be confirmed by the colored layer 2b. In particular, when shipped from a manufacturer to a pharmacy or hospital, a plurality of eye drops are stored in a packaging box and stored in the packaging box or stored in a medicine cart at a pharmacy or hospital. There are many cases. At this time, since the eye drop container 3 stored in the packaging box or in the medicine cart can only see the top surface 4a of the cap part 4, the eye drop container 3 is lifted and the content of the label on the side of the container main body 5 is shown. It is necessary to check the drug name and content display on the label. However, when the colored layer 2a is formed on the cap portion top surface 4a as shown in FIG. 7, it can be identified by the color of the colored layer 2a, and the contents can be easily identified.

Next, another embodiment of the present invention will be described. Here, the same members as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.
FIG. 8 is a developed front view of the label in the second embodiment, and FIG. 9 is an external perspective view of the eye drop container packaged by the label. As shown in FIG. 8, the label 11 is provided with a knob portion 6. This knob portion 6 is connected to perforation lines 71 and 72 for opening the label 11, and is formed so as to protrude from the upper end portion of the first region 1A. The colored layer 21 is formed including the knob portion 6.

  According to this structure, when the knob portion 6 is formed, when the label 11 is opened, the perforation lines 71 and 72 formed in the first region 1A are broken with the knob portion 6 and further continued. The perforated lines 73 and 74 can be broken and opened, so that the label 11 can be opened easily. In the present embodiment, as the form of the perforation line, the perforation line 74 formed at the boundary between the first region 1A and the second region 1B, and obliquely upward from the perforation line 74 to the side opposite to the unsealing twist direction of the cap portion 4 The perforation line 73 extending obliquely to the perforation line, the perforation line 71 formed so as to be connected to the perforation line 73 from one side edge of the knob portion 6, and the perforation line 73 from the other side edge of the knob portion 6. And a perforation line 72 formed so as to be interrupted midway. The first region 1A of the label 11 that wraps the cap portion 4 is removed by being broken along the perforation lines 71, 72, 73, 74, but the second region 1B having the adhesive applied to the back surface is the container body. Since it is fixed to the 5 barrels, a predetermined display can be left on the 5 barrels of the container body.

  And by forming the knob part 6 as the colored layer 21 as shown in FIG. 10, the position of the knob part 6 is easy to understand, and furthermore, the colored layer 21 is provided largely on the cap part top surface 4a. When viewed, it becomes easier to identify.

  Next, FIG. 11 shows a third embodiment of the label of the present invention. In the configuration of FIG. 1, the colored layer 2 is formed along the upper end side of the first region 1 </ b> A of the label 1, but in the configuration of FIG. 11, the colored layer 22 is positioned away from the upper end side of the first region 1 </ b> A. The eye drop container 3 is packaged by heat contraction so as to be positioned including the periphery of the top surface 4a of the cap portion 4. Thus, even if a transparent region is included in the portion covering the top surface 4 a of the cap part 4, the colored layer 22 is arranged on a part of the top surface 4 a and a part of the peripheral side surface of the cap part 4. When the eye drop container 3 is viewed from above and from the side, the colored layer 22 can be confirmed. Therefore, the content can be determined by the colored layer 22. Furthermore, since this colored layer 22 is formed in the circumferential direction including the periphery of the top surface 4a, it is confirmed by checking whether the colored layer 22 portion is distorted when viewed from above the eye drop container 3. The degree of heat shrinkage can be determined.

  Next, as a fourth embodiment, as shown in FIG. 12, band-shaped colored layers 23 a and 23 b may be provided on the portion covering the top surface 4 a of the cap portion 4 and the peripheral side surface of the cap portion 4, respectively. . Also with this configuration, it is possible to determine the quality of the heat shrinkage by the distortion of the colored layer 23, and the eye drop container 3 by the colored layer 23a formed on the top surface 4a and the colored layer 23b formed on the peripheral side surface. The contents can be identified when viewed from above and from the side. Furthermore, since the label can be varied not only by the color of the colored layer 23 but also by the arrangement of the colored layers 23a and 23b, the label has a large number of distinctiveness. For example, when the content is 0.05%, the colored layer 2 is formed as one strip as in the first embodiment shown in FIG. 4, and when the content is 1%, the colored layer 23a shown in FIG. The distinctiveness can be given by changing the arrangement of the colored layers, for example, by forming it as two lines 23b.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these forms, In the range of the same identity as the invention embodied in these, it can change suitably and can implement. For example, the present embodiment mainly exemplifies a label used for an eye drop container that mainly stores a liquid. However, pharmaceuticals such as tablets, capsules, fine granules, granules, powders, and liquids, and contents other than pharmaceuticals are used. You may apply to the container which accommodated. The label of the present invention can be applied to various containers in addition to plastic, glass, PET bottles and the like.

  According to the present invention, it is possible to easily determine whether the thermal contraction of the label is good or not by checking whether or not the colored layer formed on the label has a full circumference along the shape of the top surface of the cap portion without causing distortion. Can be determined. Furthermore, when a colored layer is provided on the peripheral side surface, the colored layer can be easily identified by the colored layer because the colored layer can be confirmed from both the upper surface direction and the side surface direction of the container.
