Abstract
Description
Technical Field
[0001] The present invention relates to a roll seal, and more particularly to a roll seal formed by rolling a backing tape printed with a seal, which is easy to handle, and in particular, to a roll seal from which the seal can be easily peeled off from the backing paper.
Background Art
[0002] Generally, a roll seal is formed by printing a seal 25 on a printing tape 24 of a material tape 21 in which a printing tape 24 is laminated on a backing tape 22 via an adhesive layer 23 (Figs. 7(A) and (B)), making a half-cut line 26 around the seal 25 and performing a half-cut process (Fig. 7(C)), then trimming (Fig. 7(D)), or winding it into a roll without trimming to produce a product. In the case of this conventional roll seal, a finger is placed on the back surface of the backing tape 22 to lift the edge of the seal 25, and the seal 25 is pinched with the fingertips of the other hand and peeled off for use. However, the peeling operation is not always easy, and since the fingertips come into contact with the adhesive part on the back surface of the seal, there is a problem that subsequent operations such as the seal adhesion operation are difficult to perform.
[0003] As another type of roll seal, there is one in which the above-mentioned backing tape is absent and seals with a release paper fixed to the back surface are connected in series. Also, there is a decorative seal formed in a tape shape with a part overlapped and wound around a core roll material. However, in these cases as well, there is a difficulty in the operation of peeling off the decorative seals one by one during use, and there is a problem that a plurality of decorative seals may be peeled off at once when peeling them off.

Embodiment for Carrying Out the Invention
[0015] The embodiment for carrying out this invention will be described with reference to the accompanying drawings. The roll seal which concerns on this invention is formed by laminating a printing tape 4 via an adhesive layer 3 on a backing tape 2 having a peeling function, and a seal 5 is printed on the printing tape 4 of the material tape 1. The periphery of the seal 5 is half - cut (half - cut line 6) leaving a part, and the non - half - cut part around the seal 5 is full - cut (full - cut line 7), whereby the fully - cut part of the seal 5 remains in a protruding state to become a picking part 8, and the backing tape 2 remains on its back surface. Typically, it is made into a product by being roll - wound.
[0016] The picking part 8 may be formed on one side in the width direction of the material tape 1 (Figs. 1, 2), or on both sides thereof (Figs. 3, 4), and the backing tape 2 remains on the back surface of each picking part 8 by applying a half - cut line 6 (Fig. 2). In a preferred embodiment, a sub - material 11 is also appropriately printed on the peripheral part of the seal 5 of the printing tape 4 (see Figs. ①, ⑥). The seals 5 may all have the same design, or may be in a state where different designs are mixed as in the illustrated example.
[0017] The manufacturing method of the roll seal which concerns on this invention is a method for manufacturing the above - mentioned roll seal, A preparation step of preparing a material tape 1 formed by laminating a printing tape 4 via an adhesive layer 3 on a backing tape 2 having a peeling function (Fig. 1(A)); A printing step of printing a seal 5 on the printing tape 4 (Fig. 1(B)); It should be noted that in the translation of the above text, for the sake of clarity, the reference signs in the original text (such as ① and ⑥ in the Japanese text) are retained in the English translation, and it is recommended to replace them with the corresponding figure numbers in the actual English version according to the specific figure content.A half-cutting step (FIG. 1(C)) of making a half-cut by putting a half-cut line 6 around the printed seal 5 while leaving a part thereof; A full-cutting step (FIG. 1(C)) of making a full-cut by putting a full-cut line 7 around the part of the seal 5 where the half-cut was not made; A knob part forming step (FIG. 1(D)) of forming a knob part 8 by leaving the part where the full-cut of the seal 5 was made in a protruding state, and characterized in that in the full-cutting step, the ends of the full-cut lines 7 of adjacent seals 5 are connected by a full-cut connecting line 9 to form a series (FIG. 1(C)).
[0018] Hereinafter, the manufacturing method of the roll seal according to the present invention will be described in detail in the order of steps.
[0019] Preparation process First, a material tape 1 formed by laminating a printing tape 4 via an adhesive layer 3 on a base tape (separator) 2 having a peeling function is prepared (FIG. 1(A)). The material tape 1 itself is not particularly different from those used for general roll sheet manufacturing. Usually, the material tape 1 is in a roll-wound state, and while unwinding, the following processes are performed.
[0020] printing process The printing step is a step of printing the seal 5 on the printing tape 4. The printing can be performed using any printing device for tape printing, and can be printed by a printing method using a plate such as a relief plate, an intaglio plate, a lithographic plate, an inkjet method, a laser method, or any other method (FIG. 1(B)). Usually, the seal 5 is a design of a pattern, a motif, characters, or a combination thereof. In a preferred embodiment, the blank part around the seal 5 of the printing tape 4 is also appropriately printed (sub-material 11), and that part can be used separately (see FIGS. 1 and 6).
[0021] Half-cutting process The half-cut process involves cutting the printed sticker 5 in half (half-cutting) by drawing a half-cut line 6 around its perimeter, leaving a portion intact (Figures 1(C) and 4). Needless to say, half-cutting is a die-cutting process that cuts only the printing tape 4, which is the adhesive layer material, while leaving the backing tape 2 intact. Full-cutting, which will be discussed later, is a processing method that penetrates all the way through to the backing tape 2 (full die-cutting / punching). Half-cutting in this context is typically performed using a die-cutting method (Pic die / Thomson die).
[0022] Half-cutting can be performed in two ways: leaving one end of the seal 5 (one end in the width direction of the backing tape 2) intact (Figure 1(C)), or leaving both ends of the seal 5 intact (both ends in the width direction of the backing tape 2) (Figure 4). In the former case, the tab portion 8 described later will be formed on one end in the width direction of the backing tape 2 (Figure 1(D)), while in the latter case, the tab portion 8 will be formed on both ends in the width direction of the backing tape 2 (Figure 3).
[0023] Full cutting process The full-cut process involves drawing a full-cut line 7 around the portion of the seal 5 that was not half-cut and then fully cutting it (Figure 1(C)). In this case, the ends of the full-cut lines 7 around one seal 5 and the ends of the full-cut lines 7 around adjacent seals 5 are connected via a full-cut connecting line 9 to form a series of full-cut lines 10. Thus, in this full-cut process, the outside of the series of full-cut lines 10 can be separated. The full-cut process is performed on one end (Figure 1) or both ends (Figure 4) in the width direction of the backing tape 2, corresponding to the half-cut process described above.
[0024] Thumb part formation process The tab formation process involves separating the outer portion of the series of full-cut lines 10 made in the full-cut process described above, thereby forming a tab 8 while leaving the fully cut portion of the seal 5 in a protruding state (Figures 1(D) and 3). The tab 8 is formed on one end of the backing tape 2 if the full-cut lines 10 are made on one end in the width direction (Figure 1(D)), and on both ends if the full-cut lines 10 are made on both ends in the width direction of the backing tape 2 (Figure 3). The backing tape 2 remains on the back of the tab 8, but a half-cut line 6 connected to the full-cut connecting line 9 is made on the back of the tab 8 so that the remaining backing tape 2 on the back of the tab 8 can be easily removed later (see Figure 2).
[0025] Finishing process The backing tape 2, having undergone the above steps, is rolled up with the seal 5 attached to it to finish the process, and then packaged as appropriate to create the final product. The product can then be placed in a case 12 as needed for use (see Figure 6).
[0026] The roll seal according to the present invention is used in the same way as a general roll seal: the backing tape 2 is pulled out, the seal 5 is pinched and peeled off, and then it is adhered to the desired location. However, in the case of the seal 5 according to the present invention, there is a pinch portion 8 that protrudes from the backing tape 2, so the seal 5 can be easily peeled off the backing tape 2 by pinching the pinch portion 8 (see Figure 5). In particular, since the backing tape 2 portion remains on the back of the pinch portion 8, the fingertips do not come into contact with the adhesive layer 3, making it easy to handle. Furthermore, since the operation of positioning and adhering can be performed while pinching the pinch portion 8, the adhesion operation can be performed easily and quickly. The backing tape 2 portion remaining on the back of the pinch portion 8 may be left as is (the part other than the pinch portion 8 will be adhered), or it may be removed (the entire seal 5 will be adhered).
[0027] As described above, sub-materials 11 may be printed on the printing tape 4 in addition to the sticker 5. In this case, the sub-material 11 portion can be cut out in the appropriate shape using scissors or the like (see Figure 6). The backing tape 2 remains on the back of the sub-material 11 portion, so it can be removed and then adhered to any desired location. [Industrial applicability]
[0028] As described above, the roll seal and its manufacturing method according to the present invention are formed with a protruding edge that serves as a tab. By pinching and pulling the tab, the seal can be easily peeled off the backing tape. Furthermore, since the backing tape remains on the back of the tab, the seal can be applied without touching the adhesive part while holding the tab. Therefore, these peeling and application operations can be performed easily and quickly, resulting in ease of use and thus great industrial applicability. [Explanation of Symbols]
