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 having a separable display part, and more particularly, to a display layer having a display part which is detachably connected to each other, and a pressure-sensitive adhesive layer on the back surface of the display layer. And a release paper having a release treated surface combined therewith.

[0002]

2. Description of the Related Art As a delivery slip for an adhesive sheet product, for example, a product, a plurality of display slips such as an order slip on a requesting side, a management slip on an order receiving side, an affixing slip on a product, and a receiving slip at a delivery destination are collectively collected. Combinations and information of necessary items for these are commonly printed and copied. In this case, since it is printed over a plurality of display slips, it is necessary to use a dot impact printer or the like separately when copying by handwriting. For example, when it is necessary to keep a part of the display slips separated and stored in the delivery process, etc., there is also known one provided with a pseudo-adhesive layer in order to combine them so that they can be separated from each other. The layer structure of the sheet becomes complicated and the cost of the label increases.

With the recent development of OA equipment and communication means,
Since the display contents used as a copy of the conventional ordering side or order receiving side can be stored as data in the computer,
As for the delivery slips, each of the display slips is not limited to a sticky slip directly attached to a product or a receipt slip for confirming receipt at a delivery destination. In such a case,
The purpose as a delivery slip can be achieved by a configuration in which the sticky slip and the receipt slip are separated from each other as a series of forms that can be separated and the receipt slip alone is separated.

[0004] As such a delivery slip or display slip, an attached slip is fixed to a product as an adherend, and a receipt slip is detachable therefrom. In this case, if the pressure-sensitive adhesive layer on the back side of the display layer is formed by a so-called paste-less pattern or the like so that the back side of the attached form is adhesively received and the back side of the form is non-bonded, the adhesive sheet of such a pattern is individually formed. In the case of (1), since it is formed each time in accordance with the specification of the delivery slip, the production cost increases. Further, in a configuration in which the receipt form is simply connected to the affixed form by perforations or the like, there is a possibility that this portion may fall off during delivery.

[0005]

SUMMARY OF THE INVENTION The problems of the prior art are as follows.
A display layer having a plurality of display portions connected so as to be detachable, and a pressure-sensitive adhesive layer coated on the back surface of the display layer,
A release paper having a release treatment surface that is releasably combined with the adhesive layer, a cut line 6 is provided in a connecting portion between the display portions, and the release paper is separated along the boundary line. Line 8
In the pressure-sensitive adhesive sheet formed with the above, the release paper is removed from a region corresponding to the back surface of the display unit on the side from which the display layer 1 is separated, and the release remaining after removing the pressure-sensitive adhesive layer exposed in this region. A pressure-sensitive adhesive sheet having a separable display portion, wherein a sheet material is fixed so as to be flush with paper is solved by the pressure-sensitive adhesive sheet according to claim 1.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The pressure-sensitive adhesive sheet having a detachable display portion uses a normal general pressure-sensitive adhesive sheet composed of a front substrate and a release paper combined with a back surface thereof through a pressure-sensitive adhesive layer. And easily manufactured. As shown in FIGS. 1A and 1B, the existing pressure-sensitive adhesive sheet comprises a display layer 1 and a release paper 3 combined with a pressure-sensitive adhesive layer 2 coated on the back surface thereof. Is the surface 3A of the release treatment
Is releasably combined with the adhesive layer 2 on the back surface of the display layer 1.

An embodiment corresponding to claim 2 is shown in FIGS. 2 (a) and 2 (b) showing a basic procedure for producing the pressure-sensitive adhesive sheet having a separable display portion of the present invention from such a pressure-sensitive adhesive sheet. It will be described based on FIG. First, a cut line 6 for dividing the display layer 1 into a first display unit 4 and a second display unit 5 and a cut line 8 for separating the display layer 1 from the release paper 3 on the back surface are formed along the boundary. Next, an area corresponding to the back surface of the second display section 5 of the release paper 3 is cut away from the second display section 5 along the cutting line 8 and separated, and this is separated from the rear view in FIG. After turning over as shown in the cross-sectional view, it is returned to the separated position again and bonded to the pressure-sensitive adhesive layer 2. That is, the release paper 3
The area corresponding to the first display section 4 is releasably connected to the pressure-sensitive adhesive layer 2 in the area on the right side of the cutoff line 6 as in the case of a normal pressure-sensitive adhesive sheet. On the other hand, release paper 3
The area corresponding to the second display section 5 is fixed to the pressure-sensitive adhesive layer 2 on the non-peeled processing surface side 3B by the reversal so as to be non-peelable, while the lower surface of the area becomes the peeled surface 3A. I have.

When the pressure-sensitive adhesive sheet having such a separable display portion is bonded to an adherend, first, a portion of the release paper 3 corresponding to the first display portion 4 is peeled from the display layer 1. The peeling in this case is easily performed between the pressure-sensitive adhesive layer 2 and the release treated surface 3A in the same manner as a normal separator, and the pressure-sensitive adhesive layer 2 is exposed at this portion. On the other hand, a portion corresponding to the second display unit 5 is fixed to the pressure-sensitive adhesive layer 2 below the second display unit 5 by the non-peeling-treated surface 3B (FIG. 2).
(A), (b)). When the pressure-sensitive adhesive sheet in this state is adhered to an adherend (not shown), the portion of the first display unit 4 where the pressure-sensitive adhesive layer 2 is exposed on the back surface is fixed to the adherend, while the second display unit The back surface on the 5th side is a release treated surface 3A, and shows no adhesiveness at all. Therefore, this portion is very easily separated from the surface of the adherend (product) by separating the portion from the first display portion 4 along the cut line 6 as necessary.

As described above, the pressure-sensitive adhesive sheet having a detachable display portion of the present invention can be easily processed by using an existing pressure-sensitive adhesive sheet. For example, according to the design of a predetermined delivery slip,
The display unit 4 and the second display unit 5 are sectioned, a cut line 6 is formed at a position between them, and a portion of the release paper 3 corresponding to the second display unit 5 is cut off along the cut line 8 and separated. However, it can be easily made simply by reversing the front and back and returning to the portion of the second display section 5 again, and it is troublesome to manufacture a pressure-sensitive adhesive sheet in a specific pattern in each case according to the specification of the delivery slip. Does not require

Since the same release paper is bonded to both the display portions 4 and 5 on the back surface of the display layer 1 of the pressure-sensitive adhesive sheet of the present invention thus obtained, the thickness of the entire sheet is uniform. When printing is performed, there is no occurrence of print breakage at the boundary due to a step. In addition, when used by sticking to a product, the back surface of the display unit to be separated has no adhesiveness, so that it is easily separated from the product surface when separated from other portions as a copy slip.

In the embodiment used in the above description, the release paper 3 in this area is once removed so that the back surface of the display unit 5 on the side to be cut off has a function equivalent to a so-called desizing pattern, and this is reversed. Thus, the release treated surface 3A is set to be the lower surface. In this embodiment, the release paper of the pressure-sensitive adhesive sheet used as the raw material is used without waste and the processing is easy. However, in this case, since the release-treated surface 3A and the non-processed surface 3B of the release paper 3 are present on the back surface of the display layer 1, when printing with heating, the sheet is curled due to the difference in expansion and contraction due to the difference in both materials. May occur.

In the pressure-sensitive adhesive sheet according to the third aspect of the present invention, the release paper 3 in the area corresponding to the display section 5 on the side to be cut off of the display layer 1 is used instead of the reverse side. Any ordinary sheet material having no 3A may be used. The basic function and effect of this pressure-sensitive adhesive sheet are the same as those of the pressure-sensitive adhesive sheet, and a sheet material is separately used. For example, a sheet (sheet) of the same material as the release paper and not subjected to the release treatment is used. , The back surface of the adhesive sheet can be made of the same continuous material, and the curl due to the difference in expansion and contraction (between the silicon treated surface and the non-treated surface) that occurs during heating during display printing is prevented. Is done.

Although the basic structure of the pressure-sensitive adhesive sheet having a detachable display portion of the present invention has been described above, when this is applied to, for example, a combination of a sticker and a receipt used by sticking to a product, For example, it is preferable to have a specific configuration as shown in FIGS. 3 (a) and 3 (b). The essence of the embodiment according to claim 4 is that the release paper 3 corresponding to the second display portion 5 on the side to be cut off is removed while leaving a part of the edge 9 on the side opposite to the cutoff line 6. Is returned to the original area, that is, between the first display unit 4 and the edge 9. In such a configuration, when the display sheet is attached to the product, the same layer component 9 of the adhesive layer / release paper as the normal adhesive sheet remains at the edge 9 of the second display section 5, Release paper 3 of this part
The display portion 5 of the display sheet is temporarily fixed to the adherend at the sticking portion of the adhesive release layer 2 exposed at the end portion by peeling off, and does not drop off during handling. When receiving the product, the second display unit 5 can be separated between the cut line 6 and the cut line 7 penetrating near the edge.

Embodiment FIG. 3 shows an A4 size adhesive sheet having the same specifications from an original sheet.
A specific example of making an adhesive sheet having a set of separable display portions is shown. The configuration basically corresponds to FIG. 1, and the corresponding parts are denoted by the same reference numerals as those of FIG. In these figures, the pressure-sensitive adhesive sheet having a separable display portion is shown in FIG.
As shown in (a), a sticker (first display unit) 4 for a product which is connected to be detachable from each other and a receipt (second display unit) 5 with a confirmation mark or the like cut off from the delivery destination. On the surfaces thereof, description fields such as an address, a name, a code number and the like are provided in common, and each information is individually printed at the time of use.

As shown in FIG. 3 (b), a release paper 3 is adhered to the back surface of the display layer 1 via a pressure-sensitive adhesive layer 2; Is shown. Also in this embodiment, the release paper 3 in the area corresponding to the tag 4 is peeled to expose the pressure-sensitive adhesive layer 2 in that area and is fixed to the surface of the product. 3 remains fixed with the peeled surface 3A facing down,
This portion substantially floats from the surface of the product.

Here, it is desirable that the portion of the receipt 5 is always stuck to the adherend.
A cut line 8 is formed in a portion of the release paper 3 in a region corresponding to the edge (left edge) 9 of the receipt 5 and the edge 9 is cut when the receipt 5 is cut off.
Cut out the part leaving the part to be adhered.

That is, similar to the case shown in FIG.
The portion of the release paper 3 corresponding to the receipt 5 from the adhesive sheet is once separated from the pressure-sensitive adhesive layer 2 along the cut lines 8 and 8 in FIG. To the pressure-sensitive adhesive layer 2 by the non-peeling treated surface 3B.
To adhere firmly. In this case, a cut line 7 is formed at the end 9 of the receipt 5 at a portion slightly inside the cut line 8 from the cut line 8.

When this pressure-sensitive adhesive sheet is used, the release paper 3 on the back surface of the sheet is peeled off from the pressure-sensitive adhesive layer 2 at the edge 9 of the pasting slip and receipt slip 5 on the right side in FIG. Attach to the surface of the product at the part. Here, the portion of the tag 4 is entirely and completely fixed by the exposed pressure-sensitive adhesive layer 2. Most of the lower surface of the receipt 5 is a peeled surface 3A
Therefore, most parts are in a state of floating from the surface of the product, but are stopped by the partial pressure-sensitive adhesive layer 2 on the left end edge 9 and are in a state of being stuck to the product as a whole. .

When the portion of the receipt 5 is separated from this state, it is cut along cut lines 6 and 7. As described above, since the receipt 5 is not adhered to the surface of the product at all inside these cut lines, it can be easily separated from the sticker 4.

In the above-mentioned specific example, the present invention has been described with respect to a delivery slip capable of separating an attached slip and a receipt slip. However, the present invention is directed to a form or other sheet having an adhesive surface having a detachable display portion. Can be applied to products. Further, the second display portion on the side to be cut off is not limited to the specific example, and two or more display portions may be provided, and these may be formed through the cutout line or at each edge. It may be provided so that it can be separated from each other via the attached portion.

Further, the present invention can be applied to other articles based on the above-mentioned structure. For example, FIG.
By removing the release sheet 3 from the pressure-sensitive adhesive sheet shown in FIG. 1 and combining it with the pressure-sensitive adhesive layer 2 on the back surface (lower surface) of the pressure-sensitive adhesive sheet having the layer structure shown in FIG. An adhesive sheet having a separable display portion for double-sided printing having a display layer on both sides via a piece of release paper can be provided.

[0022]

As described above, the pressure-sensitive adhesive sheet having a separable display portion of the present invention can be obtained by using, for example, a raw material of a normal commercially available pressure-sensitive adhesive sheet as a material, according to the specifications of each display slip. Form the outline, separation line, and boundary line according to the required design, peel off the release paper on the lower surface corresponding to the display tag on the side to be cut off from the pressure-sensitive adhesive layer and invert it, and glue it to the original position It can be easily manufactured without giving any special layer constitution only by performing the above.

Further, in this state, the thickness of the entire layer becomes uniform, so that even when printing is performed on the entire surface after the delivery slip has been prepared, there is no possibility that, for example, a print cut due to a step may occur. Further, since the adhesive sheet having the separable display portion has a configuration in which the slips are connected in a plane, a non-impact printer that is generally used for a computer terminal or the like can be used for printing.

Further, when the receipt is separated, since the back surface has no tackiness at all, the curl does not occur at the time of peeling as in the case of peeling the removable adhesive layer or the pseudo adhesive layer, and the receipt is stored. Becomes easier.

In particular, by using the release paper corresponding to the second display portion on the side to be cut off in a pattern that leaves a portion corresponding to the bonding area on the edge, the edge is used when the display portion is used. Is reliably temporarily fixed to the adherend, and there is no possibility that the display section will fall off.

Instead of turning the release paper upside down and fixing it in the above-mentioned portion, a normal paper sheet having no release-treated surface is used in this portion, so that the material of the back surface becomes the same between the two display portions, and the display paper is printed. No risk of curling due to heating.
