[0001]
BACKGROUND OF THE INVENTION
The present invention is a multilayer label comprising an intermediate paper temporarily attached to a separator via an adhesive layer, and an upper paper that is pseudo-adhered so as not to reattach after being once peeled on the intermediate paper. A multi-layer label that can be easily and cleanly peeled off after being attached to an article to be attached, and that the peeled-off cover paper has no adhesiveness and can be suitably used for purposes other than sticking, and its production Regarding the method.
[0002]
[Prior art]
Conventionally, a multilayer label 1 as shown in FIG. 12 is known.
The label 1 has a separator 2 with a release agent processed on the surface, an intermediate paper 4 temporarily attached to the separator 2 via an adhesive layer 3, and does not reattach after being once peeled on the intermediate paper 4. In this way, the upper paper 5 is pseudo-bonded.
[0003]
In order to manufacture the multilayer label 1, as shown in FIG. 13, a flat die or a rotary die 7 having a sectional shape as shown in the figure is pressed against the base paper 6 for the multilayer label from the upper paper 5 side. A slit 8 reaching the separator 2 from the upper paper 5 is formed in the peripheral portion, and a paper piece (cass 9) around the formed label is peeled off from the separator 2 to be removed.
[0004]
In order to use the multilayer label 1 as, for example, a delivery label, first, the separator 2 is peeled off from the adhesive layer 3 on the back surface of the intermediate paper 4, and the multilayer label 1 is pasted on the surface of the package (object to be pasted). Then, after delivery of the package, the upper sheet 5 is peeled off from the intermediate sheet 4 on the package and used as a receipt.
[0005]
Here, since the upper paper 5 is pasted on the intermediate paper 4 using a technique called pseudo adhesion, the upper paper 5 once peeled off from the intermediate paper 4 is not sticky and can be used as a receipt. It has the advantage of being convenient.
[0006]
[Problems to be solved by the invention]
By the way, the multilayer label according to the above prior art has the following problems.
[0007]
That is, the separator 2 is thicker and thicker than the intermediate paper 4 and the upper paper 5, and a step is formed between the separator 2 and the intermediate paper 4 and the upper paper 5 by raising the waste. It is easy to peel the separator 2 from 1.
[0008]
However, since the intermediate paper 4 and the upper paper 5 are thin and both ends are trimmed, a nail from the periphery of the label toward the center is required to peel off only the upper paper 5 from the multilayer label 1 once attached to a package or the like. There is a disadvantage that the upper paper 5 is sometimes torn.
[0009]
The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a multilayer label that can easily peel off only the upper paper after being stuck to an article to be stuck, and a method for producing the same. .
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the invention of claim 1 includes a separator having a release agent processed on the surface, an intermediate paper temporarily attached to the separator via an adhesive layer, and once peeled on the intermediate paper. Back slit that forms a first slit that extends from the separator side to the back side of the upper paper and extends in the longitudinal direction of the base paper on one side in the width direction of the base paper for multi-layer labels composed of the upper paper that is pseudo-bonded so as not to reattach Processing step, back slit removing step of removing the intermediate paper piece, adhesive layer and separator piece from the first slit to one end side, and removing the remaining intermediate paper from the separator on a new separator larger than the full width of the upper paper Separator replacement process to be pasted, die-cutting process to cut into a label shape so as to reach the separator surface from the upper paper side including the intermediate paper missing part on one end side of the base paper, and the label part Paper over the periphery, leaving on the separator, an intermediate piece of paper and a method for manufacturing a multilayer label comprising a scum raising step of the removing the back surface of the adhesive layer.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Below, the multilayer label which concerns on Claim 1 is shown in FIG. 5, FIG. 11, and each manufacturing method is sequentially demonstrated as 1st embodiment and 2nd embodiment. In addition, the same code | symbol is attached | subjected to the component same as having demonstrated with the said prior art, and the description is abbreviate | omitted.
[0014]
1 to 5 show a first embodiment, and FIG. 1 shows a back slit processing step. In this step, a first slit 11 extending from the separator 2 side to the back surface of the upper paper 5 and extending in the longitudinal direction of the base paper 6 is formed on the left end side of the base paper 6 in the drawing. Here, the left side of the slit 11 in the figure becomes a residue 16, and the residue 16 is removed in a subsequent back slit removal step.
[0015]
Next, FIG. 2 shows a die-cutting process. In this process, a second slit 12 for separating a portion of the upper paper 5 from the periphery on the left end side in the width direction of the base paper from the first slit and the upper paper continuously therewith. A third slit 13 is formed to separate the portion 5 and the portion of the intermediate paper 4 from the surroundings. In the figure, the slit 13 reaches the pressure-sensitive adhesive layer 3, but the pressure-sensitive adhesive layer 3 may not be cut off.
[0016]
In this die cutting process, a pressing die 100 as shown in FIG. 2 can be used. The pressing die 100 has a blade 100a having a substantially square shape and three sides deeply formed, and a blade 100b having a remaining one side shallowly formed. By pressing the pressing die 100, the base paper 6 is shown in FIG. A multi-layer label 17 is formed, and a piece of paper around it becomes a residue 14.
[0017]
In the next scrap raising process, the label 17 surrounded by the second slit 12 and the third slit 13 is left on the separator 2, and the scrap 14 which is the surrounding paper piece is removed. The state after this is illustrated in the cross-sectional view of FIG.
[0018]
In the next back slit removing step, the intermediate paper piece from the first slit 11 in FIG. 4 to the left end side, the back side residue 16 composed of the adhesive layer and the separator piece on the back side thereof are removed.
[0019]
Here, either the scrap raising step or the back slit removing step may be performed first or simultaneously.
[0020]
As described above, the multilayer label 17 having a cross-sectional structure as shown in FIG. 5 is completed.
[0021]
When the separator 2 is peeled off in order to attach the multilayer label 17 to the article, it is peeled off from the stepped portion of the separator 2 on the right end side in FIG. Then, when only the upper paper 5 is peeled off from the multilayer label 17 after being attached to the article, it is easily peeled off by hooking or pinching the tab portion 18 protruding to the left end side of the upper paper 5 in the figure. Can do.
[0022]
In the following, it will be described with reference to FIGS. 6 to 11 for the second embodiment.
[0023]
FIG. 6 shows a back slit processing step similar to that of the first embodiment described above, and the first slit 11 is formed. At this time, since a residue 16 made of an intermediate paper piece, an adhesive layer and a separator piece is also formed from the slit 11 to the left end side in the figure, it is removed. This is the back slit removal step.
[0024]
Next, the remaining intermediate paper 4 is peeled off from the separator 2 (see FIG. 7), and is pasted on a new separator 19 that is larger than the entire width of the upper paper 4. At this time, an intermediate paper missing portion 20 is formed between the upper paper 5 and the separator 19 (see FIG. 8). The above is the separator replacement step.
[0025]
Next, FIG. 9 shows a die cutting process. In this step, an operation of separating the paper into a label shape is performed so as to reach the surface of the separator 19 including the intermediate paper missing portion 20 on the left end side in the drawing from the upper paper 5 side of the base paper. In this step, a pressing die such as 101 shown in the figure can be used. The pressing die 101 has a blade 101a having a substantially quadrangular shape and four sides formed at an equal depth. By pressing the pressing die 101, a multilayer label 25 as shown in FIG. Becomes dregs 14.
[0026]
In the next residue raising process, the multilayer label 25 is left on the separator, and the waste 14 consisting of the upper paper piece, the intermediate paper piece, and the adhesive layer on the back surface thereof is removed to complete the multilayer label 25 shown in FIG. To do.
[0027]
The multilayer label 25 manufactured as described above has the same effect as the multilayer label 17 according to the first embodiment because the tab portion 26 is formed on the left end side of the upper paper 5 in the drawing. Since the tab portion 26 is formed narrower than the separator 19 (because the separator 19 is formed so as to protrude in the width direction from the tab portion 26 of the upper paper 5), the adherend It is possible to prevent the upper paper 5 from being peeled off when it is struck against something before being attached to the paper. This means that once the upper paper 5 is peeled off, it cannot be used as a multilayer label. It is groundbreaking because it can cover serious drawbacks.
[0029]
【The invention's effect】
As described above in detail , according to the manufacturing method of claim 1 , a part of the upper paper is formed narrower than the separator, and this part is not sticky and protrudes in the width direction from the intermediate paper. It is possible to prevent the upper paper from being peeled off by the time signature hitting something before being attached to the object.
