Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a glass bottle,
The present invention relates to an opening confirmation label for confirming opening of containers such as plastic containers.

[0002]

2. Description of the Related Art Pharmaceuticals and the like, for example, are packed in a container comprising a main body and a cap, distributed, stored, and used. At this stage of distribution and the like, it is necessary to prevent the container from being unintentionally opened and the medicine taken out. Therefore, it is necessary to check whether the container has been opened. In addition, in the case of a so-called home medicine, only the fee for opening the package is paid, so it is necessary to confirm whether or not the container has been opened. Furthermore, when there are a plurality of containers of the same kind of medicine, it is preferable to use the medicine in the already opened container from the viewpoint of quality maintenance, so it is necessary to confirm whether the container has been opened.

[0003] As means for checking whether or not the container has been opened, the entire container may be covered with a shrink film. The shrink film is provided with a perforation at a portion corresponding to a boundary between the main body of the container and the cap. When the container is opened by rotating the cap, the shrink film breaks from this perforation. And, by this rupture, the opening of the container can be confirmed.

[0004] As another means for confirming whether or not the container has been opened, a sealing label may be used. For example, if a sealing label in the form of a cellophane tape subjected to display printing, a perforated or cut line is formed and a sealing label that breaks when it is to be peeled, and if it is formed of a film with a small tensile strength and is to be peeled, There have been proposed seal labels that break, seal labels in which a special print is applied to the glue surface, and characters appear when peeled off.

[0005]

However, when a shrink film is used as a means for checking whether or not the container has been opened, the cap is carefully rotated so as not to damage the shrink film around the perforations, and then the cap is removed. There is a problem that it is almost impossible to confirm the opening by visual inspection.

Further, in the case of the above-mentioned various sealing labels, stains due to the exudation of glue, insufficient opening confirmation, edge lift of the label, and falling off of the label due to brittleness may occur. However, there are inconveniences such as stickiness due to adhesive residue and an increase in manufacturing cost, and a satisfactory sealing label has not yet been obtained.

[0007] The present invention has been made to solve such inconvenience, and it is an object of the present invention to be able to easily confirm that a container or the like has been opened.

[0008]

Means for Solving the Problems The invention made to achieve this object comprises a base sheet layer, a synthetic resin laminate layer laminated on the base sheet layer, and an adhesive layer. And an opening confirmation label in which a quasi-adhered state is provided between the base sheet layer and the laminate layer (claim 1).

In the label for confirming the opening according to the present invention, since the space between the base sheet layer and the laminate layer is in a quasi-adhered state, when the label is applied over the container body and the cap, the cap is closed. When the container is opened by turning, the substrate sheet layer and the laminate layer are peeled off, and the opening is confirmed.

In the present invention, the peel strength between the base sheet layer and the laminate layer is set to 2 gf / 5 cm or more and 500 g.
When it is not more than f / 5 cm, it is possible to prevent unintended peeling of the base sheet layer and the laminate layer at the distribution stage or the like, and to rotate the base sheet layer and the laminate layer by rotating a normal container cap. Can be easily separated from each other (claim 2).

In these inventions, if the base sheet layer, the laminate layer and the pressure-sensitive adhesive layer are laminated in this order, and the elongation of the laminate layer is set to be larger than the elongation of the base sheet layer, the rotation of the cap is accompanied. While the laminate layer elongates, the base sheet layer cannot follow this elongation, whereby the separation between the base sheet layer and the laminate layer can be reliably achieved (claim 3). If the base sheet layer is made opaque, the laminate layer is made transparent, and a print layer is provided below the laminate layer, information can be displayed on the print layer after the base sheet layer is peeled off ( Claim 4). In addition, if the base sheet layer is made opaque, the laminate layer and the adhesive layer are made transparent, and a printing layer is provided below the adhesive layer, information is printed by the printing layer after the base sheet layer is peeled off. It can be displayed (claim 5). Further, if the base sheet layer is made opaque and a printed layer is provided below the base sheet layer, information can be displayed on the base sheet layer separated by the printed layer (claim 6).

In these inventions, if a perforation is formed in at least one of the base sheet layer, the laminate layer and the pressure-sensitive adhesive layer, the container can be opened only by rotating the cap with a relatively small force. (Claim 7).

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sectional view showing an opening confirmation label 1 according to an embodiment of the present invention. The opening confirmation label 1 is configured by sequentially laminating a base material sheet layer 3, a laminate layer 5, and an adhesive layer 7. The first print layer 9 is formed on the lower surface of the adhesive layer 7 by printing.

As the base sheet layer 3, a paper material, a synthetic resin film or the like can be used. Paper materials that can be used for the base sheet layer 3 include, for example, unbleached kraft paper, bleached kraft paper, high-quality paper, medium quality paper, single-glazed unbleached kraft paper, pure white roll, glassine paper, heat-sensitive paper, pressure-sensitive paper, Synthetic paper, Japanese paper, tracing paper, various coated papers, paperboard, liner paper and the like can be mentioned. Examples of the synthetic resin that can be used when the base sheet layer 3 is a synthetic resin film include polyethylene, polypropylene, polymethylpentene, and the like.
Examples include ethylene vinyl acetate resin, ethylene ethyl acrylate resin, ethylene acrylate resin, ethylene methacrylate resin, ethylene methyl acrylate resin, ionomer resin, polyvinyl alcohol, polyester and the like. In addition, polyethylene, polypropylene, and the like polymerized using a so-called metallocene catalyst can also be suitably used.

When a paper material is used for the base sheet layer 3, the weighing of the paper material is not particularly limited, but is generally about 30 g / m ^{2 to} 450 g / m ² . When a synthetic resin film is used for the base sheet layer 3,
Although the thickness of the synthetic resin film is not particularly limited,
Generally, it is about 8 μm or more and 100 μm or less. The base sheet layer 3 is opaque. When a synthetic resin film is used for the base sheet layer 3, it can be made opaque by dispersing a pigment or the like in the synthetic resin film.

The laminate layer 5 is formed by melting a thermoplastic resin composition, extruding the same from a T-die, and laminating the laminate on the base sheet layer 3. Examples of the thermoplastic resin usable for the laminate layer 5 include polyethylene, polypropylene, polymethylpentene, ethylene vinyl acetate resin, ethylene ethyl acrylate resin, ethylene acrylate resin, ethylene methacrylate resin, ethylene methyl acrylate resin, and ionomer resin. , Polyvinyl alcohol, polyester and the like. In addition, polyethylene, polypropylene, and the like polymerized using a so-called metallocene catalyst can also be suitably used. The thickness of the laminate layer 5 is not particularly limited, but is generally 8 μm.
The thickness is about 100 μm or less. Note that the laminate layer 5 is transparent.

The elongation of the laminate layer 5 depends on the base sheet layer 3
Is greater than the elongation. In order to make the elongation of the laminate layer 5 larger than that of the base sheet layer 3, for example, a paper material may be used for the base sheet layer 3 and a synthetic resin may be used for the laminate layer 5. When a synthetic resin film is used for the base sheet layer 3, the synthetic resin of the laminate layer 5 may be made of a material having higher flexibility than the synthetic resin of the base sheet layer 3. The term “elongation” used in the present specification means a rate of elongation when a certain tensile stress is applied. Generally, the elongation is measured at a tensile stress of 5 MPa.

The pressure-sensitive adhesive layer 7 is formed by applying a pressure-sensitive adhesive to the lower surface of the laminate layer 5. As the pressure-sensitive adhesive, various known pressure-sensitive adhesives can be used, and a water-dispersion type or a solvent type may be used. Examples of the adhesive used include an acrylic adhesive and a urethane adhesive. The coating amount of the pressure-sensitive adhesive is not particularly limited, but is generally 5 g / m ² or more in terms of solid content and 40 g / m ² or more.
g / m ² or less. The pressure-sensitive adhesive layer 7 is transparent.

The first print layer 9 only needs to display some information, and is formed by printing characters, figures, symbols, and the like. For example, by printing the letters “opened”, it is possible to indicate that the container 11 has been opened after the container 11 has been opened and the base sheet layer 3 has been peeled off, as will be described in detail later. Further, the printing layer may be formed only by coloring by so-called “solid printing”.
These printing methods are not particularly limited.

In the opening confirmation label 1, the space between the base sheet layer 3 and the laminate layer 5 is in a pseudo-adhesion state. Therefore, the base sheet layer 3 and the laminate layer 5 can be easily separated by peeling off the pseudo-adhesion portion. In the pseudo-adhesion state, both layers are adhered in a normal use state, but when both layers are separated, they are easily separated by simply pulling by hand without using a tool or the like, and simply overlapped and pressed. It means that it cannot be re-attached by itself. The pseudo-adhesion state is different from the normal lamination using an adhesive in that this “state in which re-adhesion cannot be performed simply by overlapping and pressing” is performed. Specifically, the peel strength is 2 gf / 5 cm or more and 500 gf / 5 cm
Or less, preferably 5 gf / 5 cm or more and 100 gf / 5 c
The adhesive state may be adjusted so as to be not more than m. If the peel strength is less than the above range, for example, the base sheet layer 3 may unintentionally peel from the laminate layer 5 during the distribution stage of the container 11. Conversely, if the peel strength exceeds the above range, peeling between the base sheet layer 3 and the laminate layer 5 may become difficult.

Here, a method for measuring the peel strength will be described. First, the base sheet layer 3 and the laminate layer 5 are laminated and pre-processed according to JIS-P8111, and the width is 50 m.
m and cut into a length of 200 mm to obtain a test piece. One side of the test piece is attached to a metal plate with a double-sided tape, and the metal plate is set so that the length direction of the test piece is vertical. Then, the lower portion of the test piece is peeled off, and the peeling layer is wound up to some extent and chucked. The chuck portion is pulled upward at a pulling speed of 300 mm / min to progress the peeling, and the stress during this time is measured. The average value of this stress is taken as the peel strength.

Here, a method of manufacturing the label 1 for confirming opening will be described. First, the molten synthetic resin composition is extruded from a T-die into a film, laminated on the base sheet layer 3 and pressed to form a laminate layer 5. At this time, by setting the temperature of the molten synthetic resin composition to a relatively low temperature, the pseudo-adhesion state between the base material sheet layer 3 and the laminate layer 5 can be obtained. Next, an adhesive is applied to the laminate layer 5 and dried to form an adhesive layer 7. Then, printing is performed on the pressure-sensitive adhesive layer 7 to form the first printing layer 9, and the label 1 for confirming opening is completed. Generally, release paper is provided below the pressure-sensitive adhesive layer 7, but the release paper is not provided, the release treatment is performed on the base material sheet layer 3, and the opened confirmation label in a wound state is provided. It can also be 1.

Instead of applying the pressure-sensitive adhesive to the laminate layer 5, the pressure-sensitive adhesive layer 7 can be formed by applying the pressure-sensitive adhesive to a release paper and drying it, and then bonding the resultant to the laminate layer 5. In this case, the release paper is once peeled off, and the pressure-sensitive adhesive layer 7 is printed to form the first print layer 9,
What is necessary is just to stick a release paper again.

In the opening confirmation label 1, the temperature of the molten synthetic resin is set to a relatively low temperature so that the base sheet layer 3
And the laminate layer 5 are in a pseudo-adhesion state,
Other than this, for example, (1) the molten synthetic resin composition is once cooled on a roll and then laminated with the base material sheet layer 3;
(2) The base sheet layer 3 is cooled in advance,
(3) Preliminary release treatment of the base sheet layer 3; (4) Reducing the laminating pressure between the extruded synthetic resin composition and the base sheet layer 3; (5) Adhesion to each other The pseudo-adhesion state can be achieved by means such as selecting the material of the base sheet layer 3 and the molten synthetic resin composition having a small force.

FIG. 2 is a front view showing a state in which the opening confirmation label 1 shown in FIG. The container 11 includes a main body 13 and a cap 15. The label for opening confirmation 1 is attached to the main body 13 and the container 11 by the adhesive force of the adhesive layer 7 (see FIG. 1).
It is stuck so that it straddles.

When opening the container 11, the cap 15 is turned. Then, the cap 1 of the opening confirmation label 1
5 (the upper half in FIG. 2) tends to move together with the cap 15. At this time, since the laminate layer 5 (see FIG. 1) has a large elongation, it extends and follows the rotation of the cap 15. On the other hand, since the base sheet layer 3 has a low elongation, it cannot follow the rotation of the cap 15. As a result, the base sheet layer 3 is peeled off from the laminate layer 5.
Since the laminate layer 5 and the pressure-sensitive adhesive layer 7 are transparent, the opening of the container 11 is confirmed by, for example, the first printed layer 9 (see FIG. 1) printed as “opened”. After opening, even if an attempt is made to re-attach the base sheet layer 3 to the laminate layer 5, it cannot be re-adhered simply by pressing without using an adhesive or the like, so that falsification that makes it appear as if the opening has not been performed is prevented.

It should be noted that, without providing the first print layer 9, the pigment was dispersed in the laminate layer 5 or the pressure-sensitive adhesive layer 7 to form the base sheet layer 3.
The opening may be confirmed by changing the color before and after peeling the base material sheet layer 3 to a color different from that of the base sheet layer 3. Further, a printing layer may be provided below the laminate layer 5 in place of the first printing layer 9 so that opening of the container 11 can be confirmed. In this case, the pressure-sensitive adhesive layer 7 may be opaque.

Although the opening confirmation label 1 shown in FIG. 2 is attached only to a part of the outer peripheral surface of the container 11, the opening confirming label 1 has a shape substantially equal to the outer peripheral surface of the container 11,
The opening confirmation label 1 may cover the entire surface of the container 11.

In the opening confirmation label 1, at least one of the base material sheet layer 3, the laminate layer 5, and the adhesive layer 7 is provided with a perforation at a portion corresponding to the boundary between the main body 13 and the cap 15. It may be formed. This way,
Even if the entire surface of the outer peripheral surface of the container 11 is covered with the label 1 for opening confirmation, the label 1 for opening confirmation is wrapped a plurality of times, or a plurality of sheets are laminated, the sewing machine can be rotated only by a relatively small force to rotate the cap. Since the opening confirmation label 1 is broken from the eyes, the container 11 can be easily opened.
If the breakage from the perforations occurs too easily, the upper and lower sides of the opening confirmation label 1 are separated at a stage until the base sheet layer 3 is peeled off, and it is impossible to confirm the opening. Therefore, the interval between the cuts in the perforations is preferably larger than that in a normal perforation. Further, by providing the perforation confirmation label 1 partially instead of being provided on the entire surface, the breakage of the opening confirmation label 1 can be prevented too easily.

Further, the perforation is confirmed by an opening confirmation label 1.
Is formed in the oblique direction (for example, a direction of 45 degrees) with respect to the longitudinal direction of the opening confirmation label 1 when the opening confirmation label 1 is attached by a label attaching machine (referred to as "labeler"). It becomes difficult for the user to break the waist from the eyes, and the sticking workability can be improved.

FIG. 3 is a perspective view showing a state in which the opening confirmation label 1 shown in FIG. 1 is stuck over the lid 16 and the side face 17 of the packaging box. In FIG. 3, the lid 16 is closed. When the lid 16 is lifted up in this state, the portion of the label 1 for confirming opening that is adhered to the lid 16 tends to move together with the lid 16. At this time, the laminate layer 5 (see FIG. 1) has a large elongation,
Follow the movement of 6. On the other hand, the base sheet layer 3 (see FIG. 1) cannot follow the movement of the lid 16 because the elongation is small.
As a result, the base sheet layer 3 is peeled off from the laminate layer 5. The base sheet layer 3 may be completely peeled off and fall off, or only the portion adhered to the lid 16 may be peeled off to remove the side surface 17.
And may be in a standing state. In any case, for example, the first print layer 9 printed as “opened”
(See FIG. 1), the opening of the packaging box is confirmed. After opening, even if an attempt is made to reattach the base material sheet layer 3 to the laminate layer 5, it cannot be reattached simply by pressing without using an adhesive or the like. Is done.

The label 1 for confirming opening is the same as the container 1 described above.
Not only can it be applied not only to 1 and packaging boxes, but also to applications such as sticking over the lid of a petroleum can and the can body, or sticking over the push lid of a drop candy can and the can body. it can. Further, the opening confirmation label 1 can be applied to, for example, a squeeze bottle filled with mayonnaise or the like. In this case, when the squeeze bottle is pressed and deformed by hand, the base sheet layer 3 is laminated with the laminate layer 5.
From which the opening can be confirmed.

FIG. 4A shows an opening confirmation label 18 according to another embodiment of the present invention attached to a shrink-tack packaging label 23 wound around the entire outer surface of a container comprising a main body 19 and a lid 21. FIG. 4B is a partial cross-sectional view showing a state in which the container is worn, and FIG. 4B is a partial cross-sectional view showing a state in which the container is opened.

The opening confirmation label 18 is configured by sequentially laminating a base material sheet layer 25, a laminate layer 27, and an adhesive layer 29. The configurations of the base sheet layer 25, the laminate layer 27, and the pressure-sensitive adhesive layer 29 are the same as the configurations of the base sheet layer 3, the laminate layer 5, and the pressure-sensitive adhesive layer 7 of the label 1 for opening confirmation shown in FIG. is there. The pseudo-adhesion state is provided between the base sheet layer 25 and the laminate layer 27. Perforations 31 are formed in the laminate layer 27 and the adhesive layer 29. The shrink-tack packaging label 23 has a display label layer 35 attached on a shrink film layer 33. Shrink film layer 3
Perforations 37 are formed in the third and display label layers 35. As is clear from FIG. 4A, the perforation 37 of the shrink-tack packaging label 23 is composed of the main body 19 and the lid 2.
1, but the perforation 31 of the label 18 for opening confirmation is formed slightly lower than this position.

When opening the container, the lid 21 is turned.
Then, the shrink tack packaging label 23 becomes the perforation 3
7, the upper half moves together with the lid 21. The upper half of the opening confirmation label 18 also tries to move together with the lid 21. At this time, since the laminate layer 27 has a large elongation, the laminate layer 27 extends and follows the rotation of the lid 21.
On the other hand, since the base sheet layer 25 has a low elongation, it cannot follow the rotation of the lid 21. As a result, as shown in FIG. 4B, the base sheet layer 25 is peeled off from the laminate layer 7, and
The opening of the container is confirmed. If the lid 21 is kept rotating even after the base sheet layer 25 is peeled off, the laminate layer 27 and the pressure-sensitive adhesive layer 29 break at the perforations 31. The upper half of the laminate layer 27 and the pressure-sensitive adhesive layer 29 is attached to the lid 21, and the lower half is attached to the main body 19. After opening, even if an attempt is made to re-attach the base sheet layer 25 to the laminate layer 27, it cannot be re-adhered simply by pressing without using an adhesive or the like, so that tampering that makes it appear as if the container has not been opened is prevented. You.

In FIG. 4, the opening confirmation label 18 is adhered to the outside of the shrink-tack packaging label 23. After the opening confirmation label 18 is directly adhered to the container, the shrink-tack packaging label 23 is put on the container. The container may be covered, or may be covered with a shrink-tack packaging label 23 having an opening confirmation label 18 affixed to the inside. In this case, the unsealing confirmation label 18 is not peeled off unless the shrink-tack packaging label 23 is peeled off, so that it is possible to surely prevent a drug or the like from being maliciously extracted.

FIG. 5 is a sectional view showing an opening confirmation label 37 according to still another embodiment of the present invention. The opening confirmation label 37 is configured by sequentially laminating a base material sheet layer 39, a laminate layer 41, and an adhesive layer 43. The second print layer 45 is formed on the lower surface of the base sheet layer 39 by printing. The configuration of the base sheet layer 39, the laminate layer 41, and the adhesive layer 43 of the opening confirmation label 37 is the same as that of the opening confirmation label 1 shown in FIG.
This is equivalent to the configuration of the base material sheet layer 3, the laminate layer 5, and the pressure-sensitive adhesive layer 7 described above.

In the opening confirmation label 37, the base sheet layer 39 and the laminate layer 4 are also moved by moving the cap or the like.
Peel from 1. Then, information is displayed by the second print layer 45 on the back side of the peeled substrate sheet layer 39. For example, by printing “hit” or “out”, the second print layer 4
By forming 5, the opening confirmation label 37 can be used as a lottery. In addition, by printing the application procedure and forming the second print layer 45, the base sheet layer 39 can be used as a campaign application seal.
