Abstract

To provide a tool for holding release paper, which enables anyone to easily stick various commercially available adhesive tapes to various inner corners such as a bottom corner of a corrugated fiberboard box and an internal corner of a room, and a method for using the same.SOLUTION: Thereafter, the adhesive tape is separated from the release paper holding jig while being cut into an appropriate size together with the release paper, an adhesive portion of the adhesive tape exposed from between the release papers is folded so that an adhesive surface becomes an outer side and is stuck to an arbitrary internal angle portion, and a remaining adhesive portion of the adhesive tape exposed by peeling the release paper from the adhesive tape is stuck to each internal angle surface of the arbitrary internal angle. Alternatively, substantially the same process is realized by using a perforated release paper having two parallel lines of perforations substantially at the center.SELECTED DRAWING: Figure 5

Description

[Technical Field]

[0001] To provide a release paper holding jig that enables anyone to easily apply various commercially available adhesive tapes to various interior corners, such as the bottom corner of a cardboard box or the inside corner of a room, and a method for using the same. [Background technology]

[0002] For example, when creating a work using a cardboard box or cardboard, it is easy to apply commercially available adhesive tape to the outer corners, but it is difficult to apply it to the inner corners. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 10-081861 [Patent Document 2] Patent Publication No. 2014-088520 Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention and the invention of Patent Document 1 differ in two points: whether or not they include a step of attaching an adhesive body ("adhesive tape 3" or "adhesive film 1") to a release paper ("perforated release paper 2a" or "release paper 2"), and whether or not they include a step of folding it. Since the above two steps are essential to obtain the inventive merit of "attaching a commercially available adhesive tape to the inner corner," we cannot help but think that a person skilled in the art would not have conceived of the inventive merit of obtaining the above-mentioned inventive merit even if they had simply not bothered to show each of these steps as a mere example.

[0005] The invention of Patent Document 2 is an invention of the adhesive tape itself, and does not correspond to commercially available adhesive tapes. Even if a person skilled in the art were to refer to Patent Document 1, in order to obtain the inventive merits, he or she would need to be able to realize the "step of attaching an adhesive body to a release paper." However, this would be difficult because the "release paper 26" with the "first cut 28a" and "second cut 28b" cannot maintain its substance as a single sheet of release paper without the "adhesive tape body 22" in between. [Means for solving the problem]

[0006] To provide a release paper holding jig capable of sticking various commercially available adhesive tapes to various interior corners such as the bottom corner of a cardboard box or the inside corner of a room, and a method for using the same.

[0007] The present invention provides a release paper holding jig that is made of a material having releasability, has a holding portion that holds the edge of the release paper, and is characterized in that the release paper is held in two parallel rows in the holding portion.

[0008] The present invention provides a method for applying an adhesive tape, comprising the steps of holding the release paper in two parallel rows in the release paper holding jig, applying an adhesive tape having a width spanning the two parallel rows of release paper while spanning the two parallel rows of release paper, separating the adhesive tape applied to the release paper together with the release paper from the release paper jig, folding the adhesive portion of the adhesive tape exposed between the two parallel rows of release paper so that the adhesive surface is facing outward and applying the adhesive tape to an adherend, and peeling off the release paper on both outer sides of the adhesive portion to apply the remaining adhesive portion of the adhesive tape to the adherend.

[0009] The present invention provides a method for applying an adhesive tape, comprising the steps of: applying an adhesive tape having a width spanning the two parallel rows of perforations to the perforations of a perforated release paper having two parallel perforations approximately in the center, while spanning the two parallel rows of perforations; peeling the portion of the release paper between the two parallel perforations along the perforations to expose the adhesive portion, while folding the adhesive portion so that the adhesive surface is on the outside, and applying the remaining adhesive portion of the adhesive tape to the adherend; and peeling the portions of the release paper on both sides of the adhesive portion to expose the adhesive portion. [Effects of the Invention]

[0010] According to the present invention, any adhesive tape can be used as long as the release paper is compatible with the adhesive tape used. Therefore, not only can it be used for, for example, packing tape to be stuck to the bottom corners of cardboard boxes or waterproof tape to be stuck to the inside corners of rooms, but it can also be used for, for example, Scotch tape (registered trademark) used by children when creating crafts, or when creators come up with new ways to use masking tape, and various commercially available adhesive tapes can be easily stuck to various interior corners in an attractive manner.

[0012] 1 is a diagram (one example) of the basic structure of a release paper holding jig 1 that uses release paper as the releasable material. Specifically, it is a plan view of the release paper that has multiple pairs of holding portions 1b arranged continuously on a line 1x and a line 1x'.

[0013] Figure 2 is a procedure diagram for fitting and holding release paper 2 into release paper holding jig 1. Specifically, it shows the procedure for fitting release paper 2 into holding portions 1b on line 1x and line 1x', and holding two parallel rows of release paper 2 on release paper holding jig 1 (note that although an explanatory diagram is omitted, if release paper 2 is long, it is sufficient to line up multiple release paper holding jigs 1 and hold them).

[0014] 3 is a diagram showing the procedure for applying adhesive tape 3 to release paper 2. Specifically, the procedure shows the procedure for applying adhesive tape 3 between two rows of release paper 2 held in parallel.

[0015] 4 is a procedural diagram showing how to cut the release paper 2 and adhesive tape 3 to an appropriate size to form an adhesive tape with release paper 4. Specifically, this diagram shows how to cut the adhesive tape 3 attached to the release paper 2 to the same size as the fold line of the inner corner U, and form an adhesive tape with release paper 4 of an appropriate size on the release paper holding jig 1.

[0016] 5 is a diagram showing the steps for separating the adhesive tape 4 with a release liner from the release paper holding jig 1. Specifically, the procedure for removing the adhesive tape 4 with a release liner from the holding portion 1b and separating it from the release paper holding jig 1 is shown.

[0017] Figures 6 to 8 show the procedure for producing a pressure-sensitive adhesive tape 4 with a release liner by a method different from that shown in Figures 1 to 5, and Figure 6 is a diagram showing the basic structure of the perforated release liner 2a used in that method (and also serves as a process diagram for cutting this to any size to produce the release liner 2a-cut). Specifically, the perforated release liner 2a (or release liner 2a-cut) has two parallel rows of perforations 2am approximately in the center in the longitudinal direction, with release liner regions 2a' on the inside of the two rows of perforations 2am and release liner regions 2' on both outsides.

[0018] 9 is a diagram showing the steps for producing adhesive tape 4' with release liner. Specifically, adhesive tape 3 is applied to the two rows of perforations 2am, and both ends are appropriately cut to the same dimensions as the fold lines of the inner corners U to produce adhesive tape 4' with release liner.

[0019] Figure 8 is a diagram showing the steps for peeling off the release paper portion 2a' of the adhesive tape 4' along the perforation 2am to expose the adhesive portion 3a and create the adhesive tape 4 (for convenience, Figures 7 and 8 are drawn upside down).

[0020] Figure 9 is a diagram of an adhesive tape 4 with release paper (3-cut adhesive tape with release paper 2 or release paper portion 2' on both sides of the adhesive portion 3a exposed, trimmed to the same dimensions as the fold line of the inner corner portion U).

[0021] Figure 10 shows procedural diagrams (1) and (2) illustrating the process of attaching 3-cut adhesive tape to the inner corner U. Specifically, procedural diagram (1) illustrates the process of folding the adhesive tape 4 with release paper into a V shape so that the adhesive portion 3a is on the outside, and procedural diagram (2) illustrates the process of folding it completely flat and then attaching the adhesive portion 3a to the inner corner U while aligning it with the fold line.

[0022] Figure 11 shows procedural diagrams (3) and (4) illustrating the process of applying 3-cut adhesive tape to the inner corner U. Specifically, procedural diagram (3) shows the adhesive portion 3a of the adhesive tape 4 with release paper appropriately applied to the fold line of the inner corner U, and procedural diagram (4) shows the process of peeling off the release paper 2 (or release paper portion 2') on one side of this.

[0023] Figure 12 shows procedural diagrams (5) and (6) illustrating the process of attaching the 3-cut adhesive tape to the inner corner U. Specifically, procedural diagram (5) illustrates the process of attaching the adhesive portion of the 3-cut adhesive tape exposed in step (4) to the corresponding location of the inner corner U and peeling off the other side of the release paper 2 (or release paper portion 2'), and procedural diagram (6) illustrates the process of attaching the adhesive portion of the 3-cut adhesive tape exposed through step (5) to the corresponding location of the other inner corner U.

[0024] Figure 13 is an illustration showing an example in which adhesive tape 3-cut (e.g., duct tape) has been attached to the bottom corners of the storage box 300 shown in Figures 28 to 39 of Patent Application No. 2024-11120 (devised by the present inventor) in a way that looks attractive.

[0025] Figure 14 shows an example of an image of adhesive tape 3-cut (e.g., waterproof tape) being applied to the corner of a room in an attractive manner. [Explanation of symbols]
