Description

  The present invention relates to a tamper-proof label seal that prevents unauthorized opening or tampering in a packaging container.

Conventionally, as a tamper-resistant technique for preventing tampering in packaging containers for foods, etc., a tamper-proof label seal using a method of sticking a seal across a main body container and a cap to form a seal mark ( Hereinafter, it may be abbreviated as a label seal).
In addition, it is known that a non-adhesive region is provided on the adhesive surface of the label seal so that the presence or absence of opening can be easily detected.

  In the label seal that is pasted between the main body container and the lid, a non-adhesive area is provided in the middle area of the seal, and both end areas are provided as adhesive areas provided with an adhesive layer in the adhesive area. The thing provided with the slit for a fracture | rupture is proposed (for example, patent document 1).

Further, in the label seal that is folded and stuck between the main body container and the lid, the inner surface area of the seal is set as a non-adhesive surface area, and the peripheral surface area is set as an adhesive surface area. Have been proposed so as to face each other and cut lines extending from the left and right edges of the label seal to the inner surface area are provided on both the left and right sides (for example, Patent Document 2).
JP 2002-162909 A JP 2003-26240 A

When the label seal described in Patent Document 1 is peeled off when the lid is removed from the container and opened, the label seal breaks along the incision, so that the label seal breaks even after being reattached after opening. The trace of remains. In addition, when there is an irregularity such as cutting the intermediate area with a blade or the like, the part is lifted from the container, and it is possible to determine the presence or absence of unauthorized opening from these appearance abnormalities. .
However, in the label seal described in Patent Document 1, although the above-described configuration can prevent the container from being tampered with and the contents tampered with, the seal must be multi-layered, which increases costs due to an increase in man-hours and the like. . In addition, when a general consumer opens, it takes time and effort to break the label seal starting from the breaking notch, and it is difficult to remove the label seal, and after opening, a part of the label seal is stuck on the container or lid There is a risk of remaining.

In the label seal described in Patent Document 2, when the label seal is to be peeled off from the container surface, the label seal is torn along the incision line in the inner surface area and the incision line in the peripheral surface area, and is distorted or twisted. It is possible to determine the presence or absence of opening by causing a shape change such as a slight lift.
However, the label seal described in Patent Document 2 has a configuration in which only a cut line is provided as a starting point for breaking the label seal, and the seal material, the area of the adhesive region, the position and size of the cut, etc. are appropriate. Otherwise, the label seal could be peeled without breaking, that is, it could be tampered with. Also, when opening a general consumer, it takes time and effort to break the label seal starting from the score line, and it is difficult to remove the label seal, and after opening, a part of the label seal remains attached to the container or lid. There was a fear.

In a conventional label seal for sealing, a non-adhesive region is provided on the label seal adhesive surface, so that when the label seal is broken, the label seal is lifted, twisted, etc., so that the presence or absence of opening can be easily detected. It was said.
However, a person who intends to tamper may peel off the adhesive region by, for example, inserting a wire or the like into the non-adhesive region provided on the label seal, and affix the label seal again after the unauthorized tampering. There was also a risk that unauthorized tampering could be facilitated. Further, when the position and size of the cut, the seal material, and the like are not appropriate, the label seal is peeled off without the cut line or the like being the starting point of breakage, and there is a risk of being tampered with easily.

  The present invention has been made in view of the above circumstances, and provides a tamper-proof label seal that can be easily peeled off when a general consumer opens it during use, while preventing tampering with a simple configuration. With the goal.

In order to solve the above problems, the present invention is a tamper-proof label seal in which an adhesive material is applied to the entire surface of any one of the seals, and is pasted across the boundary between the container body and the cap. A perforation is provided in a boundary region between the main body and the cap, the seal is made of a uniaxially stretched film, and a plurality of incisions are provided in parallel with the extending direction of the seal at a plurality of peripheral portions of the seal, The thickness of the seal is in the range of 20 μm or more and 70 μm or less, the pitch of the cut portion in the peripheral edge is in the range of 2 mm or more and 5 mm or less, and the length of the cut portion is in the range of 2 mm or more and 5 mm or less. A tamper-proof label seal is provided.
In the tamper-proof label seal of the present invention, it is more preferable that the pressure-sensitive adhesive material has a pressure-sensitive adhesive strength according to JIS Z-0237 of 7.8 N / 25 mm or more and 17 N / 25 mm or less.

The tamper-proof label seal of the present invention is provided with a perforation in the boundary region between the container main body and the cap, the seal is made of a uniaxially stretched film, and a plurality of peripheral portions of the seal are provided with cut portions in parallel with the seal stretching direction, The thickness of the seal is in the range of 20 μm to 70 μm, the pitch at the periphery of the cut portion is in the range of 2 mm to 5 mm, and the length of the cut portion is in the range of 2 mm to 5 mm.
Thereby, it breaks along the seal extending direction only by applying a slight tensile force to the tamper-proof label seal. Further, when a general user opens the container for use, the perforation is broken by turning the cap, and the tamper-proof label seal can be peeled off from the perforation break line.
Therefore, it becomes possible to prevent tampering due to unauthorized opening, and a general user can easily peel off the tamper-proof label seal without leaving a part of the seal or an adhesive.
Further, in the tamper-proof label seal of the present invention, the adhesive material is configured with an adhesive strength in the range of 7.8 N / 25 mm or more and 17 N / 25 mm according to JIS Z-0237.
As a result, when the label seal is peeled off, the adhesive having strong adhesiveness causes a large distortion if it is forcibly peeled off, and the breakage starting from the score line is likely to occur, so that the presence or absence of opening can be easily detected.
Therefore, tampering due to unauthorized opening can be prevented.

Embodiments of the tamper-proof label seal according to the present invention will be described below with reference to the drawings.
1 and 2 are diagrams for explaining the tamper-proof label seal of this embodiment. This label seal (tamper-proof label seal) 1 is made of a uniaxially stretched film, and is shown in FIGS. 1 (a) and 1 (b). As shown, a pressure-sensitive adhesive layer 3 is formed by applying a pressure-sensitive adhesive 31 to one entire surface of a seal substrate (seal) 2.
Further, as in the example shown in FIGS. 2A and 2B, the label seal 1 of the present embodiment straddles the boundary between the container main body 61 and the cap 62 when used by being attached to the container 6. In the label seal 1, the perforation 4 is provided in the boundary region between the container main body 61 and the cap 62 (near the approximate center in the vertical direction in FIG. 1A).
Cut portions 5 are provided in a plurality of locations on the peripheral edge portion 1a of the label seal 1 in parallel with the extending direction A of the seal base material 2, and the thickness of the seal base material 2 is in the range of 20 μm to 70 μm. The pitch P of the cut portions 5 in the portion 1a is in the range of 2 mm to 5 mm, and the length L of the cut portions 5 is in the range of 2 mm to 5 mm.
In the label seal 1 of the present embodiment, the adhesive material 31 is configured with an adhesive strength according to JIS Z-0237 in the range of 7.8 N / 25 mm to 17 N / 25 mm.

  The label seal of the present embodiment is used by sticking it to a container that accommodates various products such as food and non-chemicals that need to be tampered with. In this embodiment, the label seal 1 is seasoned. An example of sticking to the container 6 in which the fee or the like is stored will be described.

Although the material which comprises the sealing base material 2 consists of resin materials, such as PP (polypropylene) and PET (polyethylene terephthalate), for example, it is not limited to these resin materials, Using various materials used as a sealing material Can be configured.
As described above, the thickness of the sealing substrate 2 is preferably in the range of 20 μm to 70 μm. When it is attempted to peel off the label seal 1 for the purpose of unauthorized tampering by setting the thickness of the seal substrate 2 within the above range, as described later, it is possible to detect that the label has been removed illegally. When the label seal 1 is broken and a general user opens the container 6, the label seal 1 can be easily peeled off.
If the thickness of the seal substrate 2 is less than 20 μm, the strength of the label seal 1 becomes insufficient, and the user may have difficulty peeling off the label seal 1. Moreover, 20 micrometers is the minimum thickness which can affix the label seal 1 without a problem using a label applicator.
If the thickness of the sealing substrate 2 exceeds 70 μm, the label seal 1 may not be broken when an unauthorized opening is attempted, and it may be difficult to detect the presence or absence of the opening. Further, at the time of opening, it becomes difficult to break the label seal 1 from the perforation 4 provided in the boundary region between the container main body 61 and the cap 62, which may make it difficult to open.

The pressure-sensitive adhesive layer 3 is a layer in which a pressure-sensitive adhesive 31 is applied to one side of the seal substrate 2 and functions as a sticking surface when the label seal 1 is stuck to a container 6 or the like.
The pressure-sensitive adhesive 3 can be an acrylic strong pressure-sensitive adhesive or the like, but is not particularly limited, and various materials used for sticking seals can be used.
Moreover, as mentioned above, it is preferable that the adhesive 31 used for the label seal 1 of this embodiment is configured with an adhesive strength according to JIS Z-0237 in the range of 7.8 N / 25 mm to 17 N / 25 mm. . By constructing the adhesive 31 in the above-mentioned range of adhesive strength, it becomes difficult to remove the label seal for the purpose of unauthorized tampering, while the general user can easily remove the label seal. .
If the adhesive strength of the adhesive 31 is less than 7.8 N / 25 mm, the adhesive strength of the label seal to the container or the like will be reduced, it will be easy to peel off the label seal, and unauthorized tampering may be possible. There is.
When the adhesive strength of the adhesive 31 exceeds 17 N / 25 mm, the workability when a general user peels off the label seal is lowered, and a part of the sealing equipment 2 or the adhesive 31 may remain in the container 6. There is.

As described above, when the label seal 1 is attached to the container 6 so as to straddle the boundary between the container body 61 and the cap 62, the perforation 4 is formed between the container body 61 and the cap 62 in the label seal 1. It is provided in the boundary area.
When the label seal 1 of the present embodiment is used by being attached to a container such as the container 6, the container 6 is removed by breaking the perforation 4 when the container body 61 and the cap 62 of the container 6 are separated and opened. Open.
As shown in FIG. 2 (b), the label seal 1 broken at the position of the perforation 4 is separated as seal pieces 11 and 12 in a state of being stuck to the container body 61 and the cap 62.

The cut portions 5 are provided at a plurality of locations on the peripheral edge portion 1 a of the label seal 1 in parallel along the extending direction A of the seal base material 2 constituting the label seal 1. In the example shown in FIG. 1A, a total of 20 incisions 5 are provided on the peripheral edge 1 a of the label seal 1.
In the illustrated example, incisions 51 configured perpendicular to the extending direction are provided at a total of four locations near both ends of the perforation 4.

It is preferable that the notch part 5 is the range whose pitch P in the peripheral part 1a is 2 mm or more and 5 mm or less. By setting the pitch P of the cut portions 5 in the above-described range, when the label seal 1 is to be peeled off from the peripheral portion 1a, the label seal 1 is easily broken from the cut portions 5 as a starting point. Thereby, presence / absence of opening can be detected, and unauthorized tampering can be prevented.
When the pitch P of the cut portions 5 is less than 2 mm, when a general user peels off the label seal, it is likely to break halfway, and it may be difficult to remove. Further, depending on the material of the label seal (for example, a material that is easy to extend, such as PP), there is a possibility that the break starting from the cut portion 5 is less likely to occur when the label seal is opened illegally.
If the pitch P of the cut portions 5 exceeds 5 mm, the label seal 1 starting from the cut portions 5 is less likely to break, and may be peeled off without being broken, thus preventing unauthorized tampering. There is a risk that it will not be possible.
Moreover, it is preferable that the length L of the notch part 5 is the range of 2 mm or more and 5 mm or less. By setting the length L of the cut portion 5 in the above-described range, when the label seal 1 is to be peeled off from the peripheral portion 1a, the label seal 1 is easily broken from the cut portion 5 as a starting point. Thereby, presence / absence of opening can be detected, and unauthorized tampering can be prevented.
If the length L of the cut portion 5 is less than 2 mm, the label seal 1 starting from the cut portion 5 is less likely to break and may be peeled off without being broken. There is a risk that it cannot be prevented.
When the length L of the cut portion 5 exceeds 5 mm, a general user tends to break halfway when the label seal is peeled off, which may make it difficult to peel off. In particular, when the label seal is made of a thin material, as the length L becomes longer, the label seal is easily twisted, and only a part surrounded by the cut portion 5 is broken, which may make it difficult for the user to peel off.

The label seal 1 of the present embodiment has the following effects due to the configuration described above.
As shown in FIG. 2A, the label seal 1 is stuck between the container body 61 and the cap 62 of the container 6.
When a general user opens the container 6 and intends to use the contents, the threaded cap 62 is rotated in the R direction (see FIG. 2B) to be screwed to the container body 61. The cap 62 can be removed. Along with this, the label seal 1 was broken from the position of the perforation 4, and was divided into a seal piece 11 attached to the container body 61 side and a seal piece 12 attached to the cap 62 side. It becomes a state.
By removing the seal pieces 11 and 12 from the respective rupture portions 41 and 42, the label seal is removed from the container 6.
At this time, since the cut portions are not provided in the respective rupture portions 41 and 42, when the seal pieces 11 and 12 are peeled from the container 6, the seal pieces 11 and 12 can be peeled off without breaking. it can. Thereby, it becomes possible to peel off beautifully, without a part of label seal and adhesive remaining on the container 6.

On the other hand, when the container 6 is opened to try to tamper with the contents contained in the container 6, the tamper attempts to peel off the label seal 1 without leaving any trace.
At this time, for example, when a tamper attempts to peel off the label seal 1 from the peripheral edge 1a, only a slight force is applied to the label seal 1, and any one of the cut portions 5 provided at a plurality of locations is removed. As a starting point, the label seal 1 breaks along the extending direction of the seal substrate 2.
Further, when the tamper attempts to peel off the label seal 1 from the vicinity of the boundary region between the container main body 61 and the cap 62, the label seal 1 is broken from the notch 51 provided near the perforation 4. Occurs.
Furthermore, the label seal 1 uses a strong adhesive having an adhesive strength in accordance with JIS Z-0237 in the range of 7.8 N / 25 mm to 17 N / 25 mm as the adhesive 31 so that the tamper can label. If the seal 1 is to be forcibly peeled off, the label seal 1 is greatly distorted, and breakage starting from the cut portion is likely to occur.
As a result, it is possible to prevent unauthorized persons from tampering, and even if unauthorized tampering is performed, the presence or absence of opening can be detected at a glance. be able to.

Examples of the label seal according to the present invention will be described below.
A label seal as shown in FIG. 1 was produced as a sample under the conditions of Examples described later.
Further, as the adherend to which the label seal is stuck, a glass bottle is used for the container body and a polypropylene container is used for the cap.
As an evaluation item, an evaluation test was performed for each of the following items using each sample.
