DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-adhesive label having a special structure suitable for being used for another purpose, after a label is applied to a target article and the base material is peeled off. The adhesive label of the present invention can be used to collect goods or goods when transporting goods such as a collection company, a transport company, or a delivery company, or when a mail-order company dispatches handled products according to customer orders. It is particularly suitable for use by sticking it to a pass box or the like that stores it.

[0002]

2. Description of the Related Art Information management is required when goods are distributed through many routes, cargo is transported through many transportation bases, or when materials are processed by many processing machines. Very important. In each route of distribution, each base of transportation, each process of processing, etc., grasp information about various items specific to the goods flowing there, and based on that information, appropriately adjust the transportation conditions and transportation routes. This is because it is necessary to perform measures and determinations, such as selection, processing conditions, etc., based on materials and specifications.

In addition, at each distribution / transportation base and each processing step, it is necessary to additionally input newly generated information at those locations, and it is necessary to record the information at that stage. , It is necessary to keep a copy of the label with the contents.

For this reason, conventionally, a plurality of slips are stacked and booked to form a set of sticking slips (also a label).
First, fill in the prescribed items and paste it on the article,
For each base and processing workplace as described above,
Work such as additional writing, turning over one by one from the front side, separating and storing the sheets was performed.

However, a slip on which a large number of sheets are stacked becomes thicker, which is inconvenient at the time of storing and using the slip. In many cases, the slip has a structure in which only one side is bound, and In some cases, the paper may be damaged, and when the distribution route or the transportation route is simple, a part of the paper may become unnecessary. Recently, a system has emerged that can read information from a barcode attached to a slip without having to rely on the contents of the slip. In some cases, even if the transportation route and processing steps are complicated, a large number of slips are not required. Apart from this, there is also a request to stop handwritten entry and perform batch printing with a non-impact printer.In this sense, conventional products with a structure in which many slips are bound on only one side are difficult to handle. Was.

[0006] In view of these circumstances, the inventor first,
One base material is made to be separable into two parts, one of which is used as a part of a tag for printing the address and name of the delivery destination and pasting it to the article, and the other is stamped with a receiving stamp at the destination. He proposed what was known as the "judgment" part. When using this product, first, the entire sheet is attached to an article and delivered to a delivery destination, and the "judgment" portion which is stamped at the delivery destination is separated and brought back (Japanese Patent Application Laid-Open No. Hei 9 (1999)). No.-327985).

Although this delivery slip eliminates all the drawbacks of the prior art, the separation of "stacked" slips at the peeling member of the stacked slips is not always smooth. I couldn't do it. Although the peeling member is interposed, because each layer is adhered to the extent that it does not peel off in normal handling, and to divide the base material that occupies most of the thickness and strength of the sheet in half and peel it off This is because only a very thin resin film remains on the pressure-sensitive adhesive layer in the portion after the base material has been peeled off and removed.

[0008]

In the present invention, the part to be peeled off can be peeled off smoothly, and the part is peeled off, and the remaining part after removal has sufficient strength as an adhesive label. It is an object of the present invention to provide a label which can be easily peeled off when the whole is peeled off.

[0009]

In the present invention, two substrates are used, the lower substrate supports the whole, and shares the function of attaching to the article, and the upper substrate is peeled off. By laminating as much as possible, the above problem was successfully solved.

According to a first aspect of the present invention, a releasable pressure-sensitive adhesive layer capable of repeating bonding and peeling is laminated on the back surface of the first base material, and the front surface of the first base material is provided on the back surface of the first base material. The present invention relates to a partially peelable pressure-sensitive adhesive label, wherein the second base material is laminated via an adhesive structure having no re-adhesive property after peeling.

According to a second aspect of the present invention, in the first aspect, the adhesive structure has a structure in which a peelable layer and an intermediate layer made of a synthetic resin are sequentially laminated from the second base material side. The present invention relates to a pressure-sensitive adhesive label.

[0012] The invention of claim 3 relates to the pressure-sensitive adhesive label according to claim 1 or 2, wherein the first base has a portion not covered by the second base.

According to a fourth aspect of the present invention, in the third aspect, when the entire pressure-sensitive adhesive label is peeled off on the front surface of a portion of the first base material which does not overlap with the second base material, Or a pressure-sensitive adhesive label having a symbol mark.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a basic embodiment of the pressure-sensitive adhesive label of the present invention. The pressure-sensitive adhesive label 1 is formed on a base material 2 and a back side of the base material 2 when viewed from the front side to be used. Peeled layer 3, an intermediate layer made of a synthetic resin formed on the entire back surface including the peelable layer 3, a substrate 5 different from the substrate 2, and an entire surface of the back surface of the substrate 5. The formed pressure-sensitive adhesive layer 6 and the release sheet 7 covering the entire surface of the pressure-sensitive adhesive layer 6 are laminated in this order. In the following description and drawings, for convenience, the adhesive label is cut to the size to be used and treated as if it were separated. The present invention is not limited to this, and may be a continuous sheet in which many units of the adhesive label are continuously arranged adjacent to each other. Folded at the perforation, zigzag fold
May be in a state of being overlapped.

The pressure-sensitive adhesive label 1 of the present invention comprises a peelable sheet 7
Is peeled off and then attached to an article, but may be peeled off again or peeled off and then pasted on another article. Therefore, the role of the base material 2 is various. For example, when the base material 2 is attached to an article, it has a function as a tag on which information on a delivery destination is printed. Has a role as a label. On the front side of the base material 2, in the case of this role, entry fields and items for printing or handwriting information such as the request date, the address and name of the delivery destination, the address and name of the sender, the contents, etc. Is printed in advance, and usually a bar code or a serial number is printed for each label, and a unique number is assigned to each case, and read by a bar code reader to inquire or handle detailed information. You can also record things. In other cases, depending on the purpose of pasting, the column for the date, major / middle category, minor category, etc., and subsequent handling (discount of unit price, free provision, set sale, use as a prize, etc.) ,) Are pre-printed.

The base material 2 may be peeled off when it is delivered to a delivery destination, or may be peeled off after receiving a seal for confirming receipt, so that the delivery company or the person who handled the product can collect the base material. It can also be. In this manner, the case where the seal is received for confirmation of receipt is generally called "judgment". When it is used also as "judgement", it is desirable to provide an imprint column for pressing a receiving stamp on the front side of the base material 2.

The base material 2 includes a tag, an entry such as "judgment",
It has a function of making a seal and displaying information by writing and stamping, and a base material 5 described later mainly constitutes a base material of the pressure-sensitive adhesive label of the present invention. Substrates 2, 5
When used as a delivery slip, paper such as high-quality paper is usually used, but not only functional paper with functions such as thermal recording paper and pressure-sensitive copying paper, but also plastic films, metal foil, etc. Any flexible sheet can be used in principle, and should be used properly depending on the intended use. Since various information recording methods such as printing, handwriting, and stamping are applied, when these methods are applied, characters do not bleed or repel, as a base material,
It is good to select and use those having printability, writing suitability, or sealability. As a preferred example, there is an example in which thermosensitive recording paper is used as the base material 2 and high-quality paper is used as the base material 5. In order to make printed items and entry columns easy to see, the base materials 2 and 5 are preferably those having a base concealing property, and the color is not particularly limited. However, in terms of ease of use, white or another color is used. However, those having a light color and high lightness are preferred.

A perforation 8 or the like may be formed on the substrate 2 to separate a part of the substrate 2. Perforation 8
Also, half cut, creasing, or the like may be used. In the following description, the term is used in terms of perforations, but the following description is common to half cut, creasing, and the like. FIG. 2 is a plan view showing a state in which perforations 8 are formed, and FIG.
-It is A sectional drawing. In the example shown in FIGS. 2 and 3, 2
Although the base material 2 can be separated into three parts by the perforations 8 of the book, the formation position of the perforations 8, the number of formed portions, and the shape defined by the perforations 8 are arbitrary. The depth of the perforations 8 is preferably reached to the synthetic resin intermediate layer, but it is sufficient that the perforations 8 reach the peelable layer 3 reliably.

As shown in FIG. 3, the perforations 8 may be provided in a broken line or in a continuous line. By the way, as for the end of the perforation 8, as shown in FIG. 2, it is possible to select whether the upper side and the lower side of the adhesive label 1 are divided or connected. Separation is easier when separating the components, but it is slightly easier to tear. In addition, if they are connected, careless tearing can be prevented, but they tend to be slightly difficult to tear, so the strength of the base sheet and the magnitude of the force necessary for separating the judging portion or used It is better to decide on one of them depending on the environment and other factors.

An intermediate layer 4 composed of a peelable layer 3 and a synthetic resin layer
Is an adhesion structure for adhering the base material 2 and the base material 5 on the lower side and releasably adhering the two base materials. Therefore, the role of the intermediate layer 4 is an adhesive for bonding the two substrates 2 and 5. Further, the peelable layer is directly between the two substrates,
Between the base material 2 and the intermediate layer 4,
Has a weak adhesive strength so that it can be peeled off with a relatively weak force. In order to enable peeling with a relatively weak force due to the presence of the peelable layer 3, the adhesive strength between the peelable layer 3 and the base material 2 is relatively weak, (2) There are cases where the strength between the layers of the peelable layer 3 is relatively weak, or (3) the adhesive strength between the peelable layer 4 and the base material 5 is relatively weak.

Depending on the materials of the base material 2 and the base material 5, it is possible to perform lamination in which a single layer can be peeled off without using the two layers of the peelable layer 3 and the intermediate layer 4. For example,
When one is a paper and the other is a plastic film, a synthetic resin composition that does not strongly adhere to the plastic film but penetrates the paper and thus adheres relatively strongly is used. Alternatively, when the base material 2 and the base material 5 are made of different materials such as a plastic film and a metal sheet, it is possible to select an adhesive that strongly adheres to one and relatively weakly adheres to the other.

The peelable layer 3 is relatively
It is easiest to use a material that is firmly adhered and that is selected to have a weak adhesive strength with the intermediate layer 4. Specific examples of the material include an ink containing a wax-based or silicone-based release agent, a coating agent, a PVA-LA (polyvinyl alcohol-long-chain alkyl isocyanate adduct), an acrylic resin, and a polyethyleneimine-based material. In addition, any material may be used as long as it exhibits releasability from the barrier layer. These materials are formed into a paint and applied to the substrate 2 by a printing technique such as offset printing or the like to form a peelable layer 4. In order to ensure the separation of the “read” portion, the peelable layer 3 may be provided slightly to the left of the perforations 8, that is, slightly protruding from the tag portion.

The intermediate layer 4 made of a synthetic resin stably releases the peeling property between the peelable layer 3 provided between the base material 2 and the base material 5, that is, a necessary weak adhesive force. It also has a role to maintain. The intermediate layer 4 also has a role of protecting the substrate 5 after the substrate 2 has been peeled off after the peelable layer has been removed while adhering to the substrate 2. The specific intermediate layer 4 is a layer formed by coating or printing a synthetic resin or the like. As the synthetic resin used for forming the intermediate layer 4, a polyester resin, a urethane resin such as a polyurethane resin, an acrylic resin, a vinyl acetate copolymer resin, or a thermoplastic resin such as a polyvinyl alcohol resin,
Natural rubber or synthetic rubber such as NR and SBR, PVA-LA
(Polyvinyl alcohol-long chain alkyl isocyanate adduct) or a thermosetting resin such as epoxy, and the like.
These may be used alone or as a mixture, or, if necessary, may be added with a curing agent, a crosslinking agent, a pigment, and the like. Instead of bonding the substrate 2 and the substrate 5 with the intermediate layer 4, the intermediate layer 4 is formed by forming the intermediate layer 4 and then applying an adhesive and bonding to the lower substrate 5. The adhesive may be adhered to the intermediate layer and the base material 5 as compared with a method without an adhesive layer by bonding the base material 5 and the base material 5 with an adhesive layer interposed therebetween. There are advantages.

The substrate 5 is a base portion of the pressure-sensitive adhesive label of the present invention, which maintains the strength of the pressure-sensitive adhesive label as a whole and on which a pressure-sensitive adhesive layer for forming the pressure-sensitive adhesive label is laminated. . Since the base material 5 is not located on the outermost surface unlike the base material 2, it is necessary to perform printing for giving a function of a tag or “judgment” or to form a frame or a column. Although it is thinner than the base material 2, if the base material 2 is peeled off, there is a possibility that the base material 2 can be seen through the intermediate layer 4 made of a synthetic resin layer. . The material of the substrate 5 and the necessary functions are the same as those described in the description of the substrate 2.

The removable pressure-sensitive adhesive layer 4 is for attaching the pressure-sensitive adhesive label 1 to an article, and is made of a general (meth) acrylate ester, a synthetic resin such as vinyl acetate resin, or a rubber resin such as SBR. belongs to. The re-peelable pressure-sensitive adhesive layer is made repeatable for bonding and peeling, according to the application of sticking and peeling the pressure-sensitive adhesive label several times.First, the adhesive label is applied to the article according to each individual order. Paste, then collect the same transportation route and the same delivery destination,
This is because it is necessary to peel off the once-applied adhesive label and re-attach it in another case where the packaging is to be re-packaged in individual or several packages.

The peelable sheet 7 is laminated on the pressure-sensitive adhesive layer 6 to protect the pressure-sensitive adhesive layer 6 until the label is attached to the article, and the pressure-sensitive adhesive layer 6 is inadvertently applied to another article. This is to prevent sticking. In general, even if the pressure-sensitive adhesive layer is laminated on the back surface of the sheet, if the surface of the base material has releasability, even if such an adhesive-coated sheet is wound, it can be peeled at the time of use, In the case of the present invention, printing is often performed before sticking, and if the printing surface is provided with releasability, it is usually inconsistent with the suitability of printing and the releasability, so it is difficult to design. Therefore, in the case of the present invention, it is better to laminate the peelable sheet 7 on the pressure-sensitive adhesive layer 6.

As the releasable sheet 7, a plastic film such as a polyolefin resin having low adhesiveness such as polyethylene, or a sheet having a release layer formed by coating a silicone resin or wax on the surface of paper is used. However, if printing is to be performed on the side of the release sheet 7 opposite to the side where the pressure-sensitive adhesive layer is laminated, the selection is made in consideration of printability. Usually, the pressure-sensitive adhesive layer 6 is applied and formed on the releasable sheet 7, and the pressure-sensitive adhesive layer is laminated on the base material 5 with the pressure-sensitive adhesive layer inside.

As shown in FIG. 4, the substrate 5 on the lower side of the pressure-sensitive adhesive label of the present invention may have a portion 9 not covered by the substrate 2. In FIG. 4, the right side of the base material 2 is extended to the right side, but the upper side of the base material 2 when the pressure-sensitive adhesive label 1 is viewed in a plan view (see FIG. 5) is further raised. The lower side may be further extended downward, or the left side of the substrate 2 may be extended further in the leftward extending direction. When the base material 5 is extended, the lower removable pressure-sensitive adhesive layer 6 and the releasable sheet 7 are naturally extended with the same dimensions. The advantage of extending the base material 5 in this way is that, after the adhesive label has finished its role, when it is desired to peel the adhesive label from the article, it is easy to see from where it should be removed.

As shown in FIG. 6, since it is sufficient that there is a portion where the base material 5 can be seen from above, the base material 5 is laminated so that a part of the base material 2, for example, the upper side protrudes from the upper side of the base material 5. May be. When the base material 2 protrudes as shown in FIG. 6, a peelable layer 3 and an intermediate layer may be provided on the back of the protruding portion, but it is preferable that no such layer is provided.

When the base material 2 or the base material 5 protrudes,
When processing using continuous winding as raw material,
Paper width (dimensions in the direction perpendicular to the winding direction)
If they are laminated using different materials, the production is easy.

The part 9 on the base material 5 which is not covered by the base material 2 can be provided with another notice. Since the pressure-sensitive adhesive label of the present invention is formed of two substrates,
In order to completely remove the base material 5 from the article, it is necessary to surely remove the lower substrate 5 closer to the article. Therefore, the fact is indicated by a wording or a symbol mark capable of expressing the fact. Particularly, when the base material 2 remains, it is possible to prevent the base material 2 from being erroneously peeled when such a word or a symbol mark is present when the adhesive label 1 is peeled off.

[0032]

According to the first aspect of the present invention, since the pressure-sensitive adhesive label is formed by using two base materials, the pressure-sensitive adhesive label itself has strength, and even when the above-mentioned base material is peeled off, the pressure-sensitive adhesive label is removed. There is no damage, and the part remaining after peeling has sufficient strength.

According to the invention of claim 2, in addition to the effect of the invention of claim 1, the intermediate layer made of a synthetic resin used for bonding the first base material and the second base material is used. Since the action is blocked by the peelable layer, the peeling can be reliably performed at the portion where the peelable layer is provided, and the force required for peeling (= peeling strength) can be reduced by changing the material of the peelable layer. Can be adjusted.

According to the invention of claim 3, claim 1 or 2
In addition to the effect of the invention, the first base material that is on the lower side when pasted is extended, so after sticking the adhesive label to the article and using it, when trying to peel the entire adhesive label In addition, an error in pulling and peeling the second base material hardly occurs.

According to the invention of claim 4, in addition to the effect of the invention of claim 3, the object to be peeled is specified.
It is highly effective in further preventing an erroneous attempt of pulling and peeling the base material.
