Description

Methods for attaching a label and a structure for attaching the same}

The present invention relates to a method and an attachment structure of a label by a label applicator.

In general, the label wound around the entirety imparts adhesion to the inner side of the label, and is sequentially attached to the circumference of the container from the beginning of the label, with the end of the label superimposed at the beginning.

In recent years, recycling of containers used like PET bottles has been required in view of environmental problems. It is necessary to remove the label when recycling the container.

The above-described labeling technique has the following problems.

Since the label is firmly adhered to the outer circumferential surface of the container via the <1> adhesive, it is difficult to remove the label. In particular, when the label is made of paper, the label is likely to be torn and it is very difficult to remove it cleanly.

In order to improve the removal of the <2> label, it is conceivable to use an adhesive having a weak adhesive strength.

This method is helpful for the removal of the label, but there is a problem in that the overlapping portion of the label inadvertently falls down during the distribution of goods.

As described above, the conventional attaching technique has a relationship in which the adhesiveness and the removability of the label are in contradiction and cannot satisfy these at the same time.

<3> Moreover, as a label which does not use an adhesive agent, the cylindrical label which has a seamless structure externally attached to a container is known.

While this type of tubular label is more expensive than the sheet-like label, there is no attachment position at both ends of the label, so the label must be cut off and removed, and it takes time to remove the label, There is a risk of damaging the container body.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a label applying technique capable of satisfying the adhesiveness and removability of a label at the same time.

Another object of the present invention is to provide a label attachment technique applicable to all kinds of labels.

Example 1

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 6.

<1> label

In FIG. 1, the code | symbol 10 is a container which consists of raw materials, such as paper, resin, glass, and a pottery, and the code | symbol 20 is a sheet-shaped label which consists of well-known raw materials, such as paper and resin (including heat shrinkable resin). As such, it is set to a dimension slightly longer than the outer periphery of the container 10 so that the beginning and the end of the label 20 can be superimposed and attached.

The present invention is directed to a variety of known labels used in the labeling machine, specifically, a roll label and a roll which cuts immediately before attachment to accommodate a plurality of labels in a magazine, and leaves each sheet. Shape labels, etc.

As shown in FIG. 2, a hard adhesive layer 22 is positioned at the start edge of the inner surface 21 of the label 20 to form a container adhesive layer 23, and at the end edge of the inner surface 21. The label adhesive layer 24 is formed. The poor adhesive layer 22 may be formed on a part of the inner surface 21 or the entire surface from which the label adhesive layer 24 is removed.

Although each layer of the hard adhesive layer 22, the container adhesive layer 23, and the label adhesive layer 24 may be previously formed in the label 20, it may be formed sequentially in the process of the label conveyance path | route by a label applying machine.

<2> poor adhesion layer

The hard-adhesive layer 22 is formed by performing a non-adhesive process such as directly bonding a very thin resin film or the like to a label material or printing a soft molten fluorine resin or the like.

The hard-adhesive layer 22 should just be surface-treated in order to have adhesiveness with respect to the adhesive agent in a molten state, and to remove easily with respect to the adhesive agent after hardening.

Although the case where it formed continuously in the width direction of the label 20 was shown in this Example, it may be formed in the partial range according to the formation range of the container adhesive layer 23. As shown in FIG.

<3> adhesive layer

The container adhesive layer 23 and the label adhesive layer 24 are adhesive parts, and are formed by application means or printing means for applying various known adhesives and pastes including a heat sensitive or pressure sensitive adhesive.

3 shows a cross section of the beginning of the label. (A) shows an example in which a container adhesive layer 23 is formed by applying an adhesive to the hard adhesive layer 22, and (B) shows a surface of the hard adhesive layer 22 in which a heat-sensitive or pressure sensitive capsule containing an adhesive is sealed. The example formed in FIG.

The label adhesive layer 24 is formed directly at the end of the inner side 21 of the label 20.

<4> About adhesiveness and separability of label

Until now, in order to reliably adhere the label to the container, high adhesion was given to the beginning and the end of the label, respectively.

In this regard, the present invention provides that the overlap of both ends of the label 20 is adhered with high adhesiveness, but the proper adhesion and separation between the container 10 and the beginning of the inner side 21 of the label 20 is adhered. The surname comes with it.

As a means for providing both the adhesiveness and the separability at the beginning of the inner surface 21 of the label 20, a laminated structure in which the container adhesive layer 23 is formed through the hard adhesive layer 22 is employed.

That is, both the layers 22 and 23 after curing of the container adhesive layer 23 based on the properties of the poor adhesive layer 22 while the container adhesive layer 23 itself is appropriately secured based on high adhesiveness. Separation can be given between.

The use of adhesives with low adhesive performance may be thought to result in a small separation between the label and the container, but this low adhesiveness is the performance before the adhesive cures, so that when the adhesive is cured, the label adheres firmly to the container, The separation becomes bad.

In addition, when the adhesive having low adhesive performance is used, there is a problem in that sufficient adhesive force cannot be secured when the beginning of the label is attached to the container, and the label cannot be wound around the container and attached.

Hardening of the adhesive while ensuring proper adhesion to the beginning of the label 20 by forming a container adhesive layer 23 of high adhesion through the hard-adhesive layer 22 at the beginning of the label 20 as in the present invention Separation in the latter can be ensured.

In other words, the adhesive force (temporary adhesive force) such that the label 20 does not slip for a short time until the overlapping of the edges of both ends of the label 20 is completed, the beginning of the label 20 and the container 10 It is good to be able to last in between.

Next, the attaching method of the label 20 is demonstrated.

<1> Attachment at the beginning of the label

In the label applicator (not shown), each label 20 is conveyed to the attaching stage in a state where negative pressure is attracted to the outer circumferential surface of the attaching drum.

In the conveyance process, adhesiveness is imparted to the adhesive layers 23 and 24 formed at the beginning and the end of the inner surface 21 of the label 20 in the width direction thereof. Adhesiveness is imparted by application of the adhesive, heating or the like.

The container 10 is conveyed toward the attachment stage by a screw conveyor or the like.

When the beginning of the container 10 and the label 20 reaches the attachment stage, the body portion of the container 10 in which the container adhesive layer 23 at the beginning of the label 20 rotates, as shown in FIG. 4. It is attached to the outer peripheral surface of (11).

The container adhesive layer 23 is adhered to the outer circumferential surface of the container 10 with high adhesive force, and at the same time, the container adhesive layer 23 continues to be adhered to the hard adhesive layer 22 with an appropriate degree of adhesive force.

Since the beginning portion of the inner surface 21 of the label 20 is temporarily bonded to the container, the label 10 after the beginning portion is wound and attached to the outer circumferential surface of the body portion 11 of the container 10 which is sequentially rotated. .

<2> End of label

As shown in FIG. 5, the inner surface of the label 20 in a state where the beginning of the label 20 is temporarily bonded to the outer circumferential surface of the container 10 by a stack of the hard adhesive layer 22 and the container adhesive layer 23. When the end portion of 21 overlaps with the beginning of the surface 25, the label adhesive layer 24 is bonded to the beginning of the surface 25 and is wound around the entirety of the label 20.

Since both ends of the label 20 are firmly adhered through the label adhesive layer 24, both ends of the label 20 are not separated from each other during the distribution of goods.

<3> label separation

As described above, both ends of the label 20 are reliably adhered through the label adhesive layer 24, but the beginning of the label 20 and the outer circumferential surface of the container 10 are hardened by the curing of the container adhesive layer 23. It is in the state which is easy to isolate | separate from the contact bonding layer 22. FIG.

Therefore, for the purpose of recycling the container 10, it is necessary to cut a portion of the cylindrical label 20 or to remove the overlapping positions of the edges of both ends of the label 20 to form a sheet ( 20 can be easily separated from the vessel 10.

The label 20 is separated between the cured container adhesive layer 23 and the non-adhesive layer 22 only by applying a small separation force.

6 shows the state of the container 10 after the label has been removed.

The container adhesive layer 23 remaining on the outer circumferential surface of the container 10 may be removed with a solvent or the like.

Example 2

The above-described embodiment 1 has been described in the case where the laminate of the hard-adhesive layer 22 and the container adhesive layer 23 is formed at the start edge of the inner side of the label 20, even if formed in the form shown in FIG. good.

FIG. 7A illustrates a case in which the laminate is formed on the upper and lower edges of the label 20, B illustrates a case formed at the beginning and the upper and lower edges of the label 20, and C denotes the label 20 The case where a laminated body is located here and there on an inner side is shown. What is necessary is just to select the formation form of the said laminated body in consideration of the use degree of the container 10, etc.

Since the present invention is as described above, the following effects can be obtained.

By laminating the container adhesive layer on the hard-adhesive layer formed on the inner surface of the <1> label, it is possible to secure the proper adhesion between the container and to attach the label. It can be separated simply by separation force.

Therefore, both properties of adhesiveness at the time of label application, which has been difficult to realize, and separation property between the label and the container after curing of the adhesive material can be satisfied at the same time.

Even if paper <2> label is easy to tear, it can be removed without leaving in container.

Although the cylindrical level of a <3> seamless structure is expensive, even a cheap sheet-like label can be affixed with a structure substantially the same as this.

<4> It can be applied to labels of all materials such as paper, resin, and heat-shrinkable resin, and can be applied to roll labels and leaf-shaped labels.

The <5> hard-adhesive layer can be manufactured only by processing as simple as a hard-adhesion process on the label inner surface.
