Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive seal having a printing substrate, an adhesive layer, and a release substrate printed by a printing device such as a printer.

[0002]

2. Description of the Related Art A pressure-sensitive adhesive seal for ink-jet recording generally comprises a printing base material having an ink-receiving layer formed thereon, a pressure-sensitive adhesive layer, and a release base material. The printing apparatus forms characters and images by printing, then peels off the release paper and attaches the adhesive surface to the object to be used. In addition, when used as a label or sticker, a printing substrate half-cut line of a predetermined shape is inserted in advance in the printing substrate, and this is peeled off from release paper before use. In this method, only the printing substrate and pressure-sensitive adhesive layer of the pressure-sensitive adhesive paper are cut, and the release paper is not cut. Because it is unnecessary, it is easy to use and is widely used.

[0003]

However, when the printing base material is peeled off from the release paper and pasted, the difficulty of the pasting and the finished condition after the pasting differ depending on the size of the seal. In other words, in general, when the seal is small, it is possible to easily paste it neatly at the determined position, but when the seal is large, the adhesive of the printing base material sticks to the hand, It was very difficult to stick at a prescribed position, such as sticking, and wrinkles occurred and the sticking was not possible. Furthermore, it is impossible to peel off the printing substrate once pasted when the material to be pasted is paper, and it is possible to peel it off when the material to be pasted is plastic, metal, etc. It was not possible to peel off the pasted material and replace it, such as peeling wrinkles on the printed surface of the material.

[0004] More specifically, in the case of a household videotape seal or a business card size sticker, it can be stuck to a specified position accurately and without wrinkles. When a sticker having the same size as a government-made postcard is accurately attached to a government-made postcard, a part of the seal sticks out of the government-made postcard, or a wrinkle is generated on the seal. Further, even when the position of the sticking is not specified, sticking wrinkles are apt to occur in a seal larger than a postcard and it is very difficult to handle. This tendency is remarkable especially when the thickness of the seal (printing base material) is thin, and when the material is a thin sheet of plastic, there is also an effect of static electricity, etc. It cannot be attached.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem. Even if a relatively large pressure-sensitive adhesive seal is used, it can be accurately formed at a specified position without causing wrinkles. It is an object of the present invention to provide a pressure-sensitive adhesive seal that can be stuck neatly.

[0006]

According to the present invention, there is provided a pressure-sensitive adhesive seal comprising at least a printing substrate, a pressure-sensitive adhesive layer and a release substrate, wherein the printing substrate has a plurality of seals. A pressure-sensitive adhesive seal comprising: an easy-to-separate means that can be separated; and an easy-to-separate means formed on the release substrate at a position corresponding to the vicinity of the outer periphery of each of the seals.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the pressure-sensitive adhesive seal of the present invention will be described below in detail with reference to the drawings.

FIGS. 1 to 3 show a first embodiment of a pressure-sensitive adhesive seal according to the present invention. FIG. 1 is a sectional view of the pressure-sensitive adhesive seal, and FIG. FIG. 3 is a plan view as viewed from the base material side, and FIG.

The pressure-sensitive adhesive seal of the present invention comprises a printing substrate 1 to be printed by a printing apparatus, a pressure-sensitive adhesive 2 laminated on a non-printing surface of the printing substrate 1, and a pressure-sensitive adhesive 2 laminated on the pressure-sensitive adhesive 2. A half-cut line 4 (hereinafter referred to as a printing substrate half), which is an easy separating means, is formed on the printing substrate 1 so that a seal (label) of a predetermined size can be formed on the printing substrate 1. Cut line) is formed. Further, a half-cut line 5 (hereinafter referred to as a “half-cut line of the release substrate”), which is a feature of the present invention, is formed on the outer edge of the seal formed by the half-cut line 4 of the print substrate. I have.

[0010] By peeling off the initial release base material 3a of the release base material 3 formed by the release base material half-cut line 5, an initial attaching portion 31 having a small area can be made to appear.

In this pressure-sensitive adhesive seal, as shown in FIG. 3, only the initial peeling base material 3a is peeled off to make the initial sticking portion 31 appear, and this portion is bonded to the sticking material 6 by the sticking material 6.
And then gradually adhere to the portion 6 to be adhered while peeling off the remaining release paper 3 so as to adhere neatly without wrinkles. It is possible to attach.

Table 1 shows the results of a study on the width a of the initial bonding portion 31 shown in FIG.
About 10 mm was preferable.

[0013]

[Table 1]

Next, FIGS. 4 and 5 show a second embodiment of the pressure-sensitive adhesive seal of the present invention. FIG. 4 shows a case where the peeling substrate half-cut line 52 is formed by perforations.
FIG. 5 shows a linear half cut having uncut portions 53 and 54 on the left and right.

In this embodiment, as shown in FIG. 6, after the initial bonding portion 31 is peeled off at a half-cut line portion provided on a release substrate typified by a perforation and aligned, By gradually pulling the bent portion 32, the adhesive portion can be exposed to perform bonding. Of course, it may be cut from the perforation and used as in the first embodiment.

In the case of being used only by bending, the half-cut line of the release substrate may not be half-cut. For example, a bendable embossing line may be provided on the release substrate 3. . In addition, not a complete half cut for the release substrate, but an incomplete half cut with a cut line about half the thickness of the release substrate,
A configuration that facilitates bending is also highly useful.

In any case, the adhesive seal shown in the second embodiment is an initial sticking portion 31 at the tip of the adhesive seal.
Since the release base material is not cut off, there is no easy peeling or misalignment when handling the seal or when transporting it with the printer, there is no transport trouble with the printer, and it is extremely safe for the printing device. Is one of the very important effects.

Although not shown, various types of half-cuts shown in FIGS. 4 and 5 such as rough perforations and chain lines can be used as needed.

Next, a third embodiment of the present invention will be described.

This embodiment shows a case in which a plurality of seals are arranged at intervals in a printing base material, and is shown in FIGS. 7, 8 and 9. FIG.

FIG. 7 shows the planar shape of the seal of this embodiment, and FIG. 8 shows the state of the cross section. In the drawing, reference numeral 12 denotes a printing base material provided on the printing base material 1 in an adhesive seal. In the seal constituted by the half cut line 4, two release substrate cut lines 5 indicated by broken lines are formed on a part of the release substrate facing the print substrate half cut line 4. By peeling the release substrate in the area surrounded by the two release substrate cut lines 5, the initial attachment portion 31 for each seal can be formed as shown in FIG.

In this embodiment, the initial attachment portion 31 constituted by the half cuts 5 provided on the release base material 3 is shown in a form to be removed.
It is also possible to respond by bending as shown in FIG.

Although the main embodiments of the present invention have been described above, in any of the embodiments, the initial attachment portion formed by half-cutting on the release base material is installed at the upper end of the seal. As shown in the working example,
The initial attachment portion may be provided at the lower end or the side end of the seal depending on the shape of the seal, the printing form, or the like, or may be provided partially instead of the entire end.

Incidentally, as the release base material having a half cut, one or more longitudinally arranged seals (printing base materials) may be used to facilitate peeling of the seal (printing base material) from the release base material. The vertical half-cut is disposed almost at the center, and the objects, configurations and effects of the present invention are completely different.

[0025]

As described above, the object of the present invention is to form a relatively large pressure-sensitive adhesive seal by forming a small-area initial bonding portion by half-cutting on a release base material. Can be attached to the correct position without causing wrinkles.

In addition, a small-area initial bonding portion can be accurately positioned and bonded to the set bonding position of the material to be bonded by manual operation, and the remaining peeling substrate is gradually peeled off. Since you can perform the paste operation,
It can minimize wrinkles.

Further, since the initial pasting area is small, re-pasting (re-starting) is possible. Further, except for the initial pasting portion, since the peeling base material is attached at this time, other portions (pasting) can be performed. A large effect such as an easy-to-handle seal can be obtained without inadvertently sticking to a material to be attached that is not a part or a hand that is operating.

Further, in the pressure-sensitive adhesive seal of the present invention, since the release base material of the initial sticking portion 31 at the tip is not cut off, the seal is easily peeled off or misaligned when handling the seal or when transporting it with a printer. One of the very important effects is that no printing occurs, no transport trouble occurs in the printer, and the printing apparatus is extremely safe.
