BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unsealing label which is used for unsealing a package or the like and after unsealing the package.

[0002]

2. Description of the Related Art Conventionally, as an opening label of this type,
There is one as shown in FIG .

That is, in this opening label, the label 1e is referred to as the main body surface portion 10 with the sealing piece 11 of the bag body 8 for wrapping the article 9 to be wrapped on the main body surface portion 10 as shown in FIG. It is to be attached in a state of straddling the sealing piece 11.

[0004]

However, the above-mentioned label 1e is merely a small piece made of synthetic resin or paper. In addition, the back surface of the label 1e has an adhesive 4e that adheres to the sealing target portions 10 and 11 of the package.
Was only applied to the entire surface.

Therefore, in such an unsealing label, the sealing of the package is surely performed so that the sealing target portion 1
When the adhesive force of the label to 0 and 11 is increased, the label 1e is sealed at the target sites 10 and 11 when the label is opened.
There has been a problem that the work of peeling from the sheet becomes very difficult and the workability of opening the sheet becomes very poor.

Further, such a problem is that when the packaging material of the package to which the label 1e is adhered is a soft film or paper having a low strength, the packaging material cannot be removed by forcibly peeling the label 1e. It also caused inconvenience such as damage to the appearance.

In order to solve such a problem, it is necessary to weaken the adhesive force of the label, but this does not allow reliable sealing, and it is difficult to apply it to sealing a package of food or the like. Was occurring.

Therefore, according to the present invention, even if the label is firmly adhered to the package in order to surely seal the package, the opening operation can be easily performed, and the opening operation can be easily performed. At this time, it is an object to prevent the packaging material of the package from being damaged.

[0009]

According to the present invention, the label is not attached to the packaging body by applying an adhesive to the entire back surface of the label formed into a simple small piece as in the prior art. It is constructed based on a completely new idea, which has not been seen in the past, in which a portion that is not strongly bonded is provided on the back surface of the label and the portion is broken to open the package.

That is, the means for solving the above problems of the present invention is to provide two strips 13 and 13 on the back side of which the adhesive 4 is applied and which are provided apart from each other. It is provided so as to be separable between the pieces 13 and 13 via a strip-shaped dividing means, and has an adhesive force stronger than that of the adhesive 4 on the back side of the sealing piece 13.
That is, the label base material 1 is configured with the unsealing piece 5 to which the weak adhesive 14 of FIG.

[0011]

When the label for unsealing having the above-mentioned structure is used, the label base material 1 extends over both the sealing piece of the package and the sealing target site such as the main body.
Is adhered via the adhesives 4 and 4 on the back side of the sealing pieces 13 and 13, it is possible to surely seal the sealing target site.

Further, when the unsealing piece 5 of the label base material 1 is ruptured from the sealing piece 13 through the band-shaped dividing means in the sealed state, the label base material 1 no longer has a sealing function for connecting both sealing target parts. Lose. As a result, the package can be opened.

In such an opening operation, it is not necessary to forcibly peel off the sealing pieces 13, 13 of the label base material 1 from the site to be sealed. Weak against sealing target area
The unsealing work can be performed by a simple operation of simply breaking the unsealing piece 5 adhered via the adhesive agent 14 along the band-shaped cutting means.

The adhesive 14 on the back side of the unsealing piece 5 is
Since the adhesive strength of the sealing piece 13 is weaker than that of the adhesive 4 on the back side of the sealing piece 13, it is not necessary to forcibly peel the opening piece 5 from the sealing target site when the opening piece 5 is broken and separated for opening.

[0015]

Embodiments of the present invention will be described below. In FIG. 1, reference numeral 1 is a label base material made of a desired material such as a synthetic resin film, synthetic paper, or paper, and a desired trademark or a manufacturing date (not shown) is appropriately printed on the surface thereof. There is.

Reference numerals 3 and 3 denote one side portion 1a of the label base material 1.
To the other side portion 1b are perforations as two strip-shaped dividing means engraved in parallel with each other. Both outer sides of the perforations 3 and 3 are formed as sealing pieces 13 and 13, and the perforations 3, 3 are formed.
The inside of 3 is formed as an opening piece 5. Then, pressure-sensitive adhesives 4, 4 are provided on the back surfaces of the sealing pieces 13, 13.
Is provided, and the sealing piece 1 is provided on the back side of the unsealing piece 5.
Adhesives with weaker adhesive strength than adhesives 4 and 4 on the back side of 3 and 13.
The adhesive 14 is provided .

Reference numeral 2 denotes a tab piece projecting outward from the unsealing piece 5 on the one side 1a side of the label base material 1, which is to be gripped when the label is peeled off.

Reference numeral 6 denotes a release paper attached to the back side of the label base material 1, one side surface of which is treated with silicon or the like, and the sealing pieces 13 and 4 via the adhesives 4 and 4 and the adhesive 14 . It can be connected to and separated from 13.

The unsealing label 7 according to this embodiment has the above-mentioned structure, and a bag 8 made of a synthetic resin having a food 9 such as rice balls as shown in FIG.
Described below is the case of using for sealing and opening.

First, the release paper 6 is peeled off from the opening label 7 as described above, and the main body surface portion 10 of the bag body 8 and the sealing piece 11 are removed.
The label base material 1 is attached so as to straddle and. Where 4
In A and 4A, the sealing piece 13 of the label substrate 1 is the adhesive 4,
4A and 4B show adhesive portions individually adhered to the main body surface portion 10 of the bag body 8 and the sealing piece 11 at respective positions. The unsealing piece 5 of the label base material 1 is set so as to straddle the position of the leading edge of the sealing piece 11, but the unsealing piece 5 is adhered to the bag body 8.
Temporary adhesion via adhesive 14 with weaker adhesive strength than agents 4 and 4
It is adhered in a state .

In such a packaged state, the perforation lines 3 and 3 of the label base material 1 are not easily broken unless artificial force is applied, and reliable sealing can be performed.

Next, when the consumer purchases and opens the food package, the gripping piece 2 of the label base material 1 is grasped and pulled, and the opening piece 5 is perforated as shown in FIG. It suffices to break it in a strip shape along. Line 2 perforation line 3,
The unsealing piece 5 between the three is contacted to the bag body 8 more than the adhesives 4 and 4.
Bonded in a temporarily bonded state via the adhesive 14 with weak adhesion
Because there, fracture separation position between the perforation lines 3, 3 can be done very easily. In this case, even if the sealing pieces 13 and 13 are stuck on both the main body surface portion 10 and the sealing piece 11, the breaking work along the perforation lines 3 and 3 is not performed. It can be easily performed regardless of the adhesive force of the adhesives 4 and 4. Also, the back surface of the knob 2 is also against the bag body 8.
Since they are only adhered in the temporary adhering state as described above, the picking up operation of the picking piece 2 can be easily performed.

In this way, the unsealed piece 5 of the label substrate 1
If the label is broken into strips, the label substrate 1 is divided into two at the central position as shown in FIG. Therefore, the label base material 1 no longer has the function of sealing the bag body 8, whereby the bag body can be opened.

Further, since it is sufficient to simply divide the unsealing piece 5 and it is not necessary to forcibly peel off the sealing pieces 13 and 13 in the adhesive portions 4A and 4A, the bag body 8 is formed like a thin film. Even if the material is weak, the bag 8
Will not damage. Sealing piece 13 of the label substrate 1,
Although 13 remains adhered at a predetermined position of the bag body 8, this does not cause any inconvenience in opening the bag body.

Further, since the label base material 1 is always divided when opening the bag body 8 and cannot be reused, for example, the purchaser of the package body mixes a poisonous substance into the inside of the label base material 1 and repeats the same process. Even if the label base material 1 is attached, such attachment work cannot be performed. Therefore, as long as the label base material 1 is attached to the bag body 8 in a non-breakable state, there is no possibility that poisonous substances and the like are mixed in the bag body 8. Therefore, the label base material 1 also has a function of preventing mischief on a product.

Further, the back surface of the unsealing piece 5 is in a temporarily bonded state.
However, the main body surface portion 10 is temporarily bonded via the adhesive 14.
Since it is bonded to the
It is also possible to prevent the central part of 1 from floating above the bag surface.
The label base material 1 is stopped by being caught and caught by other articles.
Prevents accidental peeling or damage.
Be done.

In each of the above embodiments, the knob piece 2 is provided on one side of the label base material 1. However, such a knob piece 2 does not necessarily have to be provided . For example, as shown in FIG. The material 1 may be formed in a simple rectangular shape or the like.

Further, the shape of the label substrate 1 may be polygonal or circular in addition to the rectangular shape as in the above embodiment,
The shape does not matter. Further, the specific material thereof is not specified at all, and it goes without saying that it may be formed of a multilayer sheet material. Furthermore, the presence or absence of printing on the surface and the specific printed pattern do not matter.

Incidentally, as shown in FIG. 6, if the post mark 12 used for product management is printed so as to extend over the area between the perforation lines 3 and 3, it is possible to sell the product such as food. An even better crime prevention effect can be obtained. That is, since the post mark 12 straddling the perforation lines 3 and 3 is broken when the package is opened, the post mark is misaligned even if it is attached to the package again. Therefore, such a post mark cannot be properly read at the cash register in the store, and it is possible to reliably determine whether or not the package is once opened.

Further, the adhesive 4 provided on the label base material 1 may be applied by being applied in a striped pattern, a grid pattern or the like, and the type of the adhesive may be various pressure sensitive adhesives as well as pressure sensitive, It may be heat-sensitive.

Further, as a band-shaped cutting means of the label base material 1,
The perforation lines 3 and 3 were used in the example, but a band-shaped division was used.
The means is not necessarily limited to this. For exampleFigure 7
As shown in (a), the width of the front and back surfaces of the label base material 1 is different.
Engraving parallel half-cut lines 3a, 3a, 3b, 3b
You may make it tear apart in strip shape like the same figure (b).

Further, the opening label according to the present invention is generally attached to a release paper for trading. For example, a large number of label substrates 1 are attached in series to the release paper formed in the shape of a long strip. Alternatively, the label may be adapted to an automatic label sticking machine.

Further, the type of the article to be packaged and the packaging form of the package are not limited at all, and can be applied to the case where the package 10 is used to seal the lid 10a and the main body 11a of the packaging box, for example. It is a thing.

The opening label of the present invention can also be used for opening other than a package.

In addition, the specific construction of each part of the present invention can be arbitrarily changed within the scope intended by the present invention.

[0036]

As described above, according to the present invention, since the label base material that is adhered across the sealing target portion is composed of the sealing piece and the opening piece as described above, the sealing target of the package is By breaking the unsealed piece of the label base material to be attached to the site through the strip-shaped cutting means, the label base material can be cut in the state where the sealing piece is stuck, and at the time of unsealing work Is no longer required to forcibly peel off all or part of the label base material firmly adhered to the sealing target area as in the past, and the label base material is firmly adhered to the sealing target area. It was very easy to open the piece by just breaking the piece.

Therefore, according to the present invention, it is possible to obtain a particular effect that both the certainty of sealing the package and the workability of opening the package can be satisfied at the same time.

Further, in the present invention, since it is not necessary to forcibly peel off the portion of the label base material that is firmly adhered to the sealing target portion, even if the sealing target portion is made of a material that is easily damaged, the sealing piece is damaged. There is an advantage that the inconvenience of unjustly damaging the appearance of the package after opening can be appropriately eliminated.

Furthermore, since an adhesive that is weaker than the adhesive on the back side of the sealing piece is provided on the back surface of the unsealing piece, the sealing piece of the label base material is temporarily adhered to the sealing target site to seal the package. It can be done tightly and the opening piece floats from the bag surface
This also has the advantage that there is no risk that the label base material will be inadvertently damaged due to a part of the label base material peeling off and being caught by another article.

Further, according to the present invention, since it is necessary to divide the label base material when opening the package, it is possible to prevent the reuse of the label base material, and to contribute to the prevention or the discovery of the poisonous substance in the package. It also has an unexpected effect.

[0041] Other, cutting work of the label substrate according to the means provided with the tab in the label substrate is further facilitated, but rich in its practicality.
