DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive sheet used by sticking to an article or the like.

[0002]

2. Description of the Related Art A pressure-sensitive adhesive sheet is used by displaying characters or the like on its surface and attaching it to an article or the like. And
When delivering an article or the like to a required delivery destination, an adhesive sheet indicating the delivery destination of the article may be attached to the article and used for delivery of the article. As such an adhesive sheet, a sheet which can be used as an adhesive label on both sides has been conventionally used. FIG. 10A is a perspective view of a part of an adhesive sheet 60 which is an example of such an adhesive sheet.

[0003] A pressure-sensitive adhesive sheet 60 shown in FIG.
Are provided, and a certain width of the release layers 53 and 55 is provided between them.
And adhesive layers 54 and 56 are provided. Release layer 53,
55 and the adhesive layers 54 and 56 are formed in a stripe shape as shown in FIG.
The release layer 53 and the adhesive layer 54 on the side of the base sheet 52 and the release layer 55 and the adhesive layer 56 on the side of the base sheet 52 are alternately arranged.

The adhesive layer 54 and the release layer 55 and the adhesive layer 56 are arranged so that the adhesive layer 54 on the base sheet 51 and the adhesive layer 56 on the base sheet 52 do not overlap in the longitudinal direction. And the release layer 53 are provided so as to face each other.

When the pressure-sensitive adhesive sheet is used as a label, the base sheet 51 and the base sheet 52 are separated from each other, and the base sheet 51 and the base sheet 52 are separated by the pressure-sensitive adhesive layer 54. The adhesive layer 56 is attached to an article or the like.

[0006]

By the way, in the pressure-sensitive adhesive sheet 60, both of the base sheets on both sides are provided with a pressure-sensitive adhesive layer on the back surface thereof, and the two base sheets are overlapped with each other. I have. By providing the pressure-sensitive adhesive layer on one substrate sheet side and the pressure-sensitive adhesive layer on the other substrate sheet side so as not to overlap with each other, the two substrate sheets can be separated from each other.

However, it has been found that such an adhesive sheet 60 has the following problems.

FIG. 10B is a plan view of a part of the back surface side of the base sheet 52 provided with the release layer 55 and the adhesive layer 56 in the adhesive sheet 60. On the end 52e of the base sheet 52, the release layer 55 is formed so as to cover the entire end 52e of the base sheet 52 so that the base sheet 51 and the base sheet 52 can be separated from each other. Have been.

When the pressure-sensitive adhesive sheet 60 is adhered to an article or the like, a certain portion including the end 52e of the base sheet 52 cannot be adhered. That is, as described above,
The release layer 5 extends over the entire area of the end 52 e of the base sheet 52.
This is because such a portion cannot be attached because of the presence of No. 5.

It has been found that when the object to be stuck has a shape that is not a flat surface and a curved surface, the end 52e of the base sheet 52 that cannot be stuck is lifted. Therefore, there has been a problem that, when affixed to an article as a label, the appearance is poor. In addition, when such an article is distributed, there is a problem that the base sheet is peeled off from the portion where the floating occurs, and the base sheet is broken.

Therefore, the present invention is to provide a pressure-sensitive adhesive sheet having a double-sided base sheet used as a label or the like, and to prevent the base sheet from floating even when the base sheet is adhered to an article having a curved surface. It is intended to provide an adhesive sheet without any.

[0012]

In order to solve the above-mentioned problems, the pressure-sensitive adhesive sheet of the present invention comprises a first base material sheet on one side and a second side laminated on the other side with a release layer and a pressure-sensitive adhesive layer interposed therebetween. The second base material sheet, the release layer and the adhesive layer, the first base material sheet side and the second base material sheet side are provided alternately in a stripe shape, The adhesive layer and the release layer on at least one of the first base sheet side and the second base sheet side are provided obliquely with respect to the base sheet (claim 1).

Thus, in the pressure-sensitive adhesive sheet of the present invention, the pressure-sensitive adhesive layer is present at any end of the base sheet on both the first base sheet side and the second base sheet side. Can be. Then, when the first base sheet side and the second base sheet side are separated from each other, and each of these base sheets is adhered to an article or the like by the adhesive layer, the surface of the article is used. Even if is a curved surface, neither the first base sheet nor the second base sheet will cause the base sheet to float on the surface of the article.

Further, the pressure-sensitive adhesive layer and the release layer provided obliquely to the base sheet may be provided on the first base sheet side and the second base sheet side. The pressure-sensitive adhesive layer and the release layer on the first substrate sheet side and the pressure-sensitive adhesive layer and the release layer on the second substrate sheet side may be provided so as to cross each other (claim 3).

Further, the first base material sheet and the second base material sheet may be formed so as to cause a difference in smoothness on the back side. Thereby, when the first base material sheet and the second base material sheet stacked via the release layer and the pressure-sensitive adhesive layer are separated from each other, they can be more easily separated.

A laminate layer is provided between the base sheet and the adhesive layer and the release layer on at least one of the first base sheet side and the second base sheet side,
The laminate layer and the base sheet can be in a pseudo-adhesion state (claim 5).

Here, the "pseudo-adhered state" means that both members are adhered in a normal use state, but when the two members are peeled off, they can be easily peeled off simply by pulling manually without using a tool or the like. It is in a state of being adhered to such an extent that it can be adhered, and means that it cannot be adhered again after being peeled off. Thereby, on the side of the base sheet on which the laminate layer is provided, the base sheet can be more easily peeled off than the laminate layer. Then, there is no adhesive residue or the like on the base sheet peeled off from the laminate layer, and it becomes possible to store the base sheet in a more complete state when it is desired to store the base sheet.

Further, the laminate layer may be provided on the first base sheet side and the second base sheet side.

In this case, a laminate layer is provided on both the first substrate sheet side and the second substrate sheet side, and the substrate sheet can be easily peeled off from the laminate layer. This makes it possible to store both of the first base material sheet and the second base material sheet in a more complete state when they are to be stored.

Further, a display surface for displaying a delivery destination of an article to which these base sheets are attached is provided on a surface of the first base sheet and the second base sheet, The display surface of the base material sheet, the first display surface for displaying the first delivery destination, the display surface of the second base material sheet,
It may be a second display surface for displaying a second delivery destination different from the first delivery destination (claim 7). Thus, the adhesive sheet of the present invention can be used as a delivery slip for delivering an article to two delivery destinations.

Further, the second display surface can be used for displaying a second delivery destination, which is a delivery destination that receives further delivery from the first delivery destination (claim 8). As a result, the pressure-sensitive adhesive sheet of the present invention can be used as a delivery slip for delivering the article to the first delivery destination and then further transferring the article to the second delivery destination.

Further, the pressure-sensitive adhesive sheet can be used for reciprocal delivery of articles, the first display surface is used for displaying an outbound destination, and the second display surface is used for displaying a return destination. (Claim 9). Thus, the pressure-sensitive adhesive sheet of the present invention can be used as a delivery slip for reciprocating delivery of articles.

The base sheet 1 side and the base sheet 2 side are separated from each other,
Each of the base sheets 1 and 2 can be attached to an article or the like and used as a label or the like.

The base sheets 1 and 2 can be provided with various printed indications on their respective surfaces. The contents displayed on the front surface include a delivery destination of the article or the like to which the base sheets 1 and 2 are stuck, a note on the article, various messages, and the like. The base sheets 1 and 2 can be formed of various paper materials or the like whose surfaces can be printed or printed.
As the paper material, high-quality paper, glassine paper, art paper, coated paper (including thermal transfer paper and inkjet paper), pressure-sensitive paper, heat-sensitive paper, resin-impregnated paper, and the like can be used. Further, cloths or various plastic films may be used for the base sheets 1 and 2.

Next, the release layers 3 and 5 and the adhesive layers 4 and 6 will be described with reference to FIG. FIG. 2A is a view of the back surface of the base sheet 1 on which the release layer 3 and the adhesive layer 4 are provided, and FIG. 2B is a view of the release layer 5 and the adhesive layer 6.
FIG. 4 is a view of the back surface of the base material sheet 2 provided with.
As shown in FIG. 2A, on the back surface of the base material sheet 1, release layers 3 and adhesive layers 4 are provided alternately in a stripe shape. The release layer 3 and the adhesive layer 4 are formed so as to be substantially parallel to the left and right ends 1 e of the base sheet 1. The base sheet 1 has left and right ends 1e, 1e.
The adhesive layer 4 is provided in a portion including

As shown in FIG. 2B, a release layer 5 and an adhesive layer 6 are alternately provided on the back surface of the base sheet 2 in a stripe shape. The release layer 5 and the adhesive layer 6
As shown in FIG. 2 (b), it is provided so as to be oblique to the base sheet 2. Thus, the release layer 5
Since the pressure-sensitive adhesive layer 6 is provided obliquely to the base sheet 2, the pressure-sensitive adhesive layer 6 is present in a portion including the left and right ends 2 e and 2 e of the base sheet 2.

Here, the release layers 3 and 5 are formed of a release agent, and can be formed of a silicone resin, a fluorine resin, or the like having excellent release properties. In addition, the adhesive layers 4 and 6 can be formed by an adhesive, and are made of rubber, acrylic,
It can be formed of a copolymer such as silicone. In particular, the use of a silicone resin is preferable because the types thereof are abundant and the range of the peeling adjustment can be widened.

The base sheet 1 and base sheet 2
May be different from each other in the smoothness of the back side. Thereby, the release layer 3 and the adhesive layer 4 on the base sheet 1 side,
When the base material sheet 1 and the base material sheet 2 superposed via the release layer 5 and the pressure-sensitive adhesive layer 6 on the base material sheet 2 side are separated from each other, they can be more easily separated.

In order to make a difference in the smoothness of the back side of the base sheet 1 and the base sheet 2, one of the back sides of the sheets 1 and 2 is made to be more uneven than the other. Good. Further, a film such as OPP may be laminated on one of the back surfaces of the sheets 1 and 2. The difference in the smoothness can also be produced by interposing a layer made of a filler between the base sheet and the release layer and the adhesive layer. The interposition of the layer made of the filler prevents the adhesive from penetrating from the adhesive layers 4 and 6 to the substrate sheets 1 and 2 when the base sheets 1 and 2 are formed of paper. There is also significance to gain. Extrusion laminates such as PVA coating agents, clay coating agents, PE and PP can be used as the filler.

Further, on the substrate sheet 1 side, a release layer and an adhesive layer which are oblique to the substrate sheet 1 can be provided. FIG. 3 is a diagram illustrating an example of the release layer 13 and the adhesive layer 14 provided to be inclined with respect to the base sheet 1. In the example of the release layer 13 and the adhesive layer 14 formed as shown in FIG. 3, the release layer 13 is attached to the base sheet 2 shown in FIG.
The adhesive layer 14 is formed so as to face and substantially coincide with the release layer 5.

Thus, the adhesive layer 14 on the base sheet 1 side
And many portions of the adhesive layer 6 on the side of the base sheet 2 do not coincide with each other. That is, when the pressure-sensitive adhesive sheet is formed by overlapping the substrate sheet 1 side and the substrate sheet 2 side, the pressure-sensitive adhesive layer 14 and the pressure-sensitive adhesive layer 6 are formed by overlapping in the longitudinal direction of the stripe. It is configured such that it is not difficult to peel off the base sheet 2 side.

When the release layer and the adhesive layer are provided obliquely on the base sheet 1, they may be provided so as to intersect with the release layer 5 and the adhesive layer 6 on the base sheet 2 side. FIG. 4 is a diagram illustrating an example of the release layer 23 and the adhesive layer 24 provided obliquely to the base sheet. In the example of the release layer 23 and the adhesive layer 24 shown in FIG.
The release layer 23 and the adhesive layer 24 on the side of the base sheet 1 are formed such that the release layer and the adhesive layer of the base sheet 2 shown in FIG.

When the release layer 23 and the adhesive layer 24 are provided as shown in FIG. 4, the adhesive layer 6 on the base sheet 2 and the adhesive layer 24 on the base sheet 1 are aligned in the longitudinal direction of the stripes. There is no overlap. Accordingly, when the pressure-sensitive adhesive sheet is formed by laminating the base sheet 1 side and the base sheet 2 side, the release layer 13 and the pressure-sensitive adhesive layer 14 shown in FIG.
And a release layer 5 and an adhesive layer 6
It is not necessary to perform positioning of the base sheet 1 side and the base sheet 2 side with high accuracy as compared with a case where the base sheet 2 side on which the is formed is overlapped to form a pressure-sensitive adhesive sheet. This is preferable because the operation is not complicated.

In particular, when the release layer 23 and the adhesive layer 24 on the base sheet 1 are made substantially perpendicular to the release layer 5 and the adhesive layer 6 on the base sheet 2, the adhesive layer 6 and the adhesive layer 2
This is preferable because the overlap with No. 4 can be further reduced.

The pressure-sensitive adhesive sheet described above can be used by peeling the base sheet 1 side and the base sheet 2 side from each other, and sticking each to a product as a label or the like. Then, according to this pressure-sensitive adhesive sheet, the base sheets 1, 2
To an article 26 having a curved surface as shown in FIG.
There is no problem even if it is stuck on. That is, as described with reference to FIG. 1 to FIG.
4, the adhesive layer 6 exists on the base sheet 2 side.
Therefore, when these base sheets 1 and 2 are adhered to an article or the like, there is no occurrence of floating at the ends of the sheets.

The pressure-sensitive adhesive sheet described above can be manufactured by a manufacturing process using a roll coater, for example. An example of such a manufacturing process will be described below using the example of the pressure-sensitive adhesive sheet 10.

First, a gravure roll in which grooves corresponding to the striped pattern of the release layer 3 and the adhesive layer 4 on the base sheet 1 are engraved endlessly, and the release layer 5 and the adhesive layer 6 on the base sheet 2 side. And a gravure roll in which grooves corresponding to the stripe pattern are engraved endlessly, and for example, silicon is applied as a release agent to these gravure rolls. Then, silicon is applied to the back surface of each of the base sheet 1 and the base sheet 2 with these gravure rolls, and a striped release layer 3 is formed on the base sheet 1 side.
To form a striped release layer 5 on the base sheet 2 side. Note that a convex roll may be used instead of the gravure roll.

Next, the step of forming the adhesive layer 4 on the base sheet 1 and forming the adhesive layer 6 on the base sheet 2 will be described with reference to FIG. FIG. 6 shows the base sheet 1
Side and the side 2 are coated with an adhesive, and the adhesive sheet 10
FIG. 4 is a diagram showing an example of a step of obtaining the above. In FIG. 6, the base sheet 1 on which the release layer 3 is formed is loaded on a take-up roll 31, and the base sheet 2 on which the release layer 5 is formed is loaded on a take-up roll 32.

An adhesive is applied to the back surface of the base sheet 1 sent from the winding roll 31 by an adhesive supply device 35. The pressure-sensitive adhesive applied to the base sheet 1 is applied substantially uniformly to the entire back surface of the base sheet 1 by the pair of comma rolls 33. In addition, comma roll 3
Instead of applying the pressure-sensitive adhesive according to 3, it is possible to use various well-known methods of applying a pressure-sensitive adhesive for applying the pressure-sensitive adhesive substantially uniformly, such as using a gravure roll.

Then, the base sheet 1 having the back surface coated with the adhesive 35 is guided to an oven 36 for drying the adhesive, and the solvent and the like in the adhesive are evaporated.
Next, the base sheet 1 side coated with the adhesive and the base sheet 2 side fed out by the take-up roll 32 are overlapped on the back side by a pressure roll 37 and the take-up roll 34 By being wound up,
The adhesive sheet 10 is used. The state of adhesion between the base sheet 1 and the base sheet 2 can be adjusted by adjusting the degree of pressing of the pressing roll 37.

The pressure-sensitive adhesive sheet of the present invention has the stripping layer and the pressure-sensitive adhesive layer in the form of stripes. As described above, the pressure-sensitive adhesive sheet is manufactured by using a roll coater to sequentially feed between gravure rolls or other rolls. It is possible. Therefore, it is suitable for mass production of the pressure-sensitive adhesive sheet, and it is easy to suppress the production cost. In addition, since the pressure-sensitive adhesive can be applied substantially uniformly to the back surface of the base sheet, no irregularities are generated when the base sheet is used as a label or the like, and no trouble occurs when printing on the base sheet. .

Next, another embodiment of the pressure-sensitive adhesive sheet according to the present invention will be described with reference to FIG. FIG. 7 is a cross-sectional view of the pressure-sensitive adhesive sheet 20 according to another embodiment, taken along the laminating direction.

The adhesive sheet 20 has a base sheet 1 and a base sheet 2 on both sides, and the release layer 3 and the adhesive layer 4 are provided as a release layer and an adhesive layer on the base sheet 1 side. The release layer 5 and the adhesive layer 6 are provided as a release layer and an adhesive layer on the base sheet 2 side. Further, a transparent laminate layer 11 is provided between the base sheet 1 and the release layer 3 and the adhesive layer 4.

The laminate layer 11 is in a pseudo-adhesion state to the base sheet 1. The laminate layer 11 which is brought into a pseudo-adhesion state with the substrate sheet 1 can be formed by melting a thermoplastic resin, extruding the same from a T-die, and laminating the substrate sheet 1.

As the thermoplastic resin usable for the laminate layer 11, for example, polyethylene, polypropylene,
Polymethylpentene, ethylene vinyl acetate resin, ethylene ethyl acrylate resin, ethylene acrylate resin,
Examples include an ethylene methacrylate resin, an ethylene methyl acrylate resin, an ionomer resin, polyvinyl alcohol, and polyester. In addition, polyethylene, polypropylene, and the like polymerized using a so-called metallocene catalyst can also be suitably used.

It should be noted that a release line (not shown) may be provided on the base sheet 1 so that release from the laminate layer 11 described later can be performed more easily. Next, a specific method of using the pressure-sensitive adhesive sheet 20 will be described.
An example in which 0 is used as a delivery slip will be described with reference to FIGS.

There is a case where a company B that sells a copying machine wants to collect an empty toner bottle from a company A that has purchased the copying machine. In this case, Company B sends a storage box for collecting the toner bottle to Company A, and Company A packs the toner box in the storage box and sends it back to Company B. Company B can collect toner bottles from company A by reciprocating the storage box. Here, Company A is the first delivery destination of the storage box, and Company B is the second delivery destination of the storage box.

In the above-mentioned company B, as shown in FIG. 8 showing the base sheet 1, the address of the first delivery destination of the company A is displayed on the front surface 7 of the base sheet 1.
On the front surface 8 of the base sheet 2, a destination of the company B, which is the second delivery destination, is displayed. The front surface 7 is a first display surface for displaying a first delivery destination, and the front surface 8 is a second display surface for displaying a second delivery destination.

The display on the base sheets 1 and 2 is conveniently performed by editing the destination using a word processor or the like and printing using a printer. In particular, when using a printer capable of printing on both sides simultaneously, the surface 7 and the surface 8
As long as there is no input error in the combination of printing for, processing can be performed at higher speed without erroneous display of the destination.

Further, in the pressure-sensitive adhesive sheet 20 according to the present invention, since there is no release paper, the thickness is 100 to 100%.
The thickness can be about 200 μm, which is a thickness that does not hinder the printing process by the printer. Note that the display of the destination on the front surfaces 7 and 8 may be performed by writing the destination by handwriting.

Next, in the above-mentioned Company B, the adhesive sheet 20
Thus, the base sheet 1 including the laminate layer 11 and the base sheet 2 are separated. Then, as shown in FIG. 9A, the base sheet 2 is first attached to the packed storage box 27, and the base sheet 1 is attached on the base sheet 2.

Further, in FIG. 9, the accommodation box 27 is illustrated as having a flat surface to which the base sheets 1 and 2 are attached, but may have a curved surface.

In performing the work of attaching these two sheets, according to the pressure-sensitive adhesive sheet 20 of the present invention, the base sheet 1
Side and the base sheet 2 side must be adhered substantially simultaneously or within a very short time. That is, when the two sheets are separated, the other one cannot exist alone because there is no release paper. As a result, even if the delivery destination of the article to be delivered is large, it is possible to eliminate the labeling error.

Further, since there is no release paper, unnecessary waste is not generated after the base sheet is pasted, and even when there are a large number of articles to which the sheet is pasted, the operation of collecting and processing the release paper is not required. You won't be bothered.

The storage box 27 on which the two base sheets 1 and 2 are superimposed is sent from Company B to Company A. Then, in Company A, after unpacking, storing the toner bottle in the storage box, and packing again, the base sheet 1 is peeled off as shown in FIG. 9B. Since the base sheet 1 is in a pseudo-adhesion state to the laminate layer 11, it can be easily peeled off.

Here, the peeled substrate sheet 1 can be stored in Company A as a slip for management of delivery and delivery of the delivery. Since the base sheet 1 is in a pseudo-adhesion state with the laminate layer 11, the base sheet 1 can be peeled off from the laminate layer 11 without being damaged, and the base sheet 1 is stored in a more complete state as a slip. can do.

When the substrate sheet 1 is peeled off, the laminated layer 11 is transparent, so that the contents 1 printed on the surface 8 of the substrate sheet 2 from above the laminated layer 11 are removed.

Is returned from Company A to Company B.

As described above, the pressure-sensitive adhesive sheet 20 of the present invention
It can be used when one article is shipped back and forth between two companies, and the base sheet 1 can be stored as a slip for managing delivery of the goods at the first delivery destination.

Further, the delivery slip of the present invention is used when one article is to be delivered from Company B to Company A and further from Company A to Company C, ie, a so-called “return box” between specific companies. "Can be used for delivery. In this case, in Company B, the address of Company A, which is the first delivery destination, is displayed on the first base sheet 1 for the adhesive sheet 20, and the second delivery destination is displayed on the second base sheet 2. Is displayed.

Then, the article having the base sheet 1 side overlaid on the base sheet 2 is delivered from Company B to Company A. Then, in Company A, the base material sheet 1 is peeled off, and the contents such as printing on the surface 8 of the base material sheet 2 are made visible, and then the article is delivered to Company C. A
In the company, the base sheet 1 can be stored in a more complete state as a management slip for article transfer.

In such a case as well, in the company B, which is the first delivery source of the article, the work of attaching the base sheets 1 and 2 to the article without mistake for two predetermined delivery destinations is performed. be able to. Further, at the first delivery destination, the base material sheet 1 can be stored as a slip for managing article transfer.

In the pressure-sensitive adhesive sheet 20, a laminate layer is provided only on the base sheet 1 side, but a laminate layer may be provided on the base sheet 2 side. That is, to explain with reference to the example of the pressure-sensitive adhesive sheet 20, a laminate layer may be further provided between the base sheet 2 and the release layer 5 and the pressure-sensitive adhesive layer 6. In this case, when used as a delivery slip, the base sheet 2 can also be stored in a more complete state as a slip.

The present invention is not limited to the case where the two base sheets 1 and 2 are used for delivering one article, but may be used for delivering each one article from one delivery source to two locations. . For example, a set of two parts forming a part of a product may need to be delivered to two specific repair shops for repair, and there may be many such sets of two parts. It can also be used in such cases.

Further, the base sheets 1 and 2 are used as delivery slips.
