Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the folding adhesive tape holder of Patent Document 1 above, during use, the elastic force of the tape support legs that support the adhesive tape roll weakens, and the pressing function deteriorates. Therefore, when cutting the adhesive tape or using it as an adhesive cleaner, the adhesive tape roll rattles and becomes difficult to handle. Also, the adhesive tape cleaner has problems such as being forced to perform setting work and removal work many times because the adhesive surface on the bottom is narrow for a large amount of dust and loose hair. Solve these problems and provide a folding adhesive tape holder with better functional beauty both functionally and design-wise.

Means for Solving the Problems

[0005] A foldable adhesive tape holder comprising an upper surface (1), tape support legs (5), (5) provided at both ends of the upper surface (1) in the longitudinal direction, a retaining cover (4) provided at one end of the upper surface (1) in the short direction, a bottom surface (2) provided on the opposite side of the upper surface (1), and side surfaces (3), (3) provided at both ends in the short direction thereof, which constitute a roll holding part (A) that holds the adhesive tape roll (9) in a cylindrical shape, The tape support legs (5), (5) are provided opposite each other at both ends in the longitudinal direction of the upper surface (1) via fold lines, and the fastening cover (4) and the side surface (3) are provided opposite each other at both ends in the short direction via fold lines. Furthermore, the four fold lines are folded in a curved fold to strengthen the upper surface (1), enhance the elasticity of the tape support legs (5), (5), and improve their durability.

[0006] Preferably, the support leg connecting parts (5'), (5') provided at the ends of the tape support legs (5), (5) are connected in an arch shape to provide a clamping part (10) that frictionally engages with the fingers of the inserted hand.

[0006] Preferably, a cutter guard portion (2') that extends beyond the cutting edge of the tape cutter portion (6) provided at the inner end of the bottom portion (2) is provided at the tip of the bottom portion (2) via a fold line portion. [Effects of the Invention]

[0007] In this invention, the folding line portion of the tape support leg, which is provided opposite the upper surface of Patent Document 1, was changed from a straight mountain fold to a curved fold with an arch structure that adds even more elastic force, thereby enhancing elasticity and improving durability. In this way, the problem was solved by simply changing the conventional folding method, without adding any new parts. Furthermore, by changing the arch angle, it is possible to provide tape holders that can be adjusted to the appropriate elasticity for each tape roll, which is not possible with conventional straight-fold designs. Furthermore, the challenge of adhesive tape cleaners having a narrow adhesive surface was addressed by providing a clamping section 10 with arched connections at both ends of the tape support legs, which have enhanced elasticity and improved durability, thereby creating an adhesive tape cleaner with an adhesive surface all around the tape holder.

[Modes for carrying out the invention]

[0009] The embodiments for carrying out the present invention will be described below with reference to Figures 1 to 10. Furthermore, (a) and (b) are provided in each drawing to make it easier to understand. [Examples]

[0010] First, as shown in the drawing of FIG. 1, an example 1 is a folding adhesive tape holder having an adhesive tape cutter function. And, FIG. 1(a) is a perspective view showing a roll holding portion A that forms a cylindrical shape to hold an adhesive tape roll 9 with tape support legs 5, 5 that are curved and folded in an arch shape to which a single layer of elastic force is applied, an upper surface portion 1, a fastening lid portion 4, and side surface portions 3, 3 provided at both ends of a bottom surface portion 2.

[0011] Also, although this figure is a tape cutter dedicated to kraft tape, for transparent PP adhesive tapes etc. where it is troublesome to easily peel off when the tip of the tape returns and adheres due to winding distortion or electrostatic action, a tape guide portion 7 that also serves as a return stopper in Example 2 is provided together with the tape cutter portion 6 to handle this. Furthermore, FIG. 1(b) is also a development view in which curved fold lines are provided on each side of the upper surface portion 1.

Example

[0012] Next, as shown in the drawing of FIG. 2, an example 2 is a folding adhesive tape holder having both functions of the adhesive cutter of Example 1 and an adhesive tape cleaner. That is, the perspective view of FIG. 2(a) uses the adhesive tape cutter of Example 1, with a tape guide portion 7 that also serves as a return stopper for the adhesive tape 9', and a tape tip attachment portion 8 that is provided on the opposite side of the tape guide portion 7 and is inverted there and pulled out along the bottom surface portion 2 to fix the adhesive surface at the tip, and can also be used as an adhesive tape cleaner. Furthermore, FIG. 2b is also a development view in which curved fold lines are provided on each side of the upper surface portion 1.

[0013] <Comparative Example 1> Next, what is shown in the drawing of FIG. 3 is Comparative Example 1 with respect to the conventional Patent Document 1. In this way, in the perspective view of FIG. 3(a), while both ends in the short side direction of the upper surface portion 1 are curved folds, the tape support legs 5, 5 at both ends in the long side direction are straight-fold mountain folds. However, the present invention shown in Figure 3(b) solves the problem of improving the elasticity of the tape support legs 5, 5 and increasing their durability by changing both longitudinal ends of the upper surface portion 1 to curved folds with an arch structure that applies even more elastic force.

[0014] [Claim 2] [Examples] Furthermore, the dual-purpose adhesive tape cleaner of Embodiment 2 of the present invention had problems such as requiring repeated setting and removal operations when dealing with large amounts of dirt and loose hair due to the narrow adhesive surface of the bottom portion 2. To solve this problem, the entire circumference of the product is made adhesive, similar to the rolling type, which is currently the mainstream adhesive tape cleaner, where you roll it around to remove dirt and loose hair. Furthermore, the problem was solved by making the entire circumference of the adhesive tape cutter an adhesive surface, allowing it to be used as an adhesive cleaner as well, tentatively named the "Ouroboros-type adhesive tape cleaner."

[0015] The present invention in Example 3 will be explained using the adhesive tape cutter of Example 1 in Figure 4. Figure 4(a) is a diagram illustrating the process of pulling out the adhesive tape 9' from the roll holding section A, using the tape cutter section 6 (which acts as the reversal section) to reverse the adhesive surface outwards, making a full circle around the outer circumference along the bottom section 2, then returning it to its original position, and finally attaching and fixing the tip of the adhesive tape 9' to the adhesive surface of the reversal section, which is the starting point. Thus, in Embodiment 3 of the present invention, the reversing part and the fixing part are a holder located at the same location.

[0016] In other words, Embodiment 3 of the present invention is like the "Ouroboros ring" used in ancient Greece, as shown in Figure 4(b). The symbol of a snake biting and swallowing its own tail to form a circle is an easily understandable image for explaining the structure of this invention, and is tentatively named "Ouroboros-type adhesive tape cleaner."

[0017] Furthermore, Figure 4(a) shows an example 3 of a foldable adhesive tape holder provided with the arch-shaped clamping portion (10) of [Claim 2]. In other words, the tape support legs 5, 5 described in [Claim 2], which enable setting and removal operations without contacting all adhesive surfaces, like the "handle" of the aforementioned rolling-type adhesive tape cleaner, are provided with a connected gripping part 10 so that the holder can be gripped with fingers inside the arch.

[0018] <Comparative Example 2> Next, Figure 5(a) is an unfolded view showing how the support leg connecting parts 5', 5' provided at the ends of the tape support legs 5, 5, as described in claim 2, are connected in the center to form an arch shape, Figure 5(b) is an unfolded view showing how the support leg connection parts 5', 5' are connected on one side to form an arch. Furthermore, the support leg connection part 5' on the hooking side is equipped with a function to adjust the length of the arch.

[0019] Next, Figure 6(a) shows a configuration in which an adhesive tape roll 9 is installed inside the holder assembled by folding Figure 5(a). Furthermore, Figure 6(b) shows the shape of the adhesive surface all around, indicating that a "tab" has been pre-made and fixed to the original adhesive surface, by folding back the adhesive surface at the tip of the adhesive tape 9' to facilitate setting and removal operations without touching the adhesive surface when pulling it out.

[0020] Next, Figure 7 illustrates the detachable, non-gripping clamping part 10 of the present invention, which, so to speak, is the "handle" of the aforementioned rolling-type adhesive tape cleaner. The diagram shows a clamping portion 10 that frictionally engages with the fingers of the inserted hand, allowing the thumb to be used freely and enabling setting and removal operations without contacting the entire adhesive surface of the holder. Figure 7(a) illustrates this, showing how several fingers other than the thumb are inserted in close contact with the arched interior, causing the inserted fingers to frictionally engage with the inner surface of the arch of the tape support leg 5 and the outer surface of the upper part 1, thereby gripping the holder.

[0021] Furthermore, Figure 7(b) shows a configuration in which the holder remains firmly gripped, even when pointed downwards without using the thumb, and the setting process is completed and the removal process is performed. For large amounts of debris and loose hair, since the entire surface is adhesive, you can start from anywhere, but first, start with the palm side, and gradually, while pressing down, turn your palm over and use your wrist to adjust the pressure on the back of your hand, etc., to remove the debris precisely.

[0022] Also, when you want to change to a new adhesive surface, remove the tab from the adhesive surface, fold it in half to seal in any debris or loose hair on the adhesive surface, and then cut it with the tape cutter part 6 and discard it. In this way, the adhesive side is folded in half before disposal, so the dirty adhesive side does not stick to the opening of the trash can or other surfaces. [Examples]

[0023] Next is Example 4, which is a specialized, nearly circular holder with an adhesive surface all around, similar to the currently mainstream rolling type, tentatively named the "Ouroboros-type adhesive tape cleaner." Here, we will explain using chart diagrams in the order of ▲1▼ to ▲4▼. First, Figure 8(a) shows the unfolded substrate of the specially designed "Ouroboros-type adhesive tape cleaner" of the present invention, which has an adhesive surface all around.

[0024] Next, Figure 8(b) is a diagram showing the unfolded substrate in the folding stage.

[0025] <Comparative Example 3> Next, Figure 9(a) shows the configuration in which a new adhesive tape roll 9 is pressed against the bottom surface 2 by tape support legs 5, 5, to which a new adhesive tape roll 9 is attached, as shown in Figure 3. Furthermore, by connecting both ends of the tape support legs 5, 5, they are integrated and work together, preventing the load from being unevenly distributed and further improving their endurance.

[0026] Next, Figure 9(b) shows a configuration in which, even when the adhesive tape roll 9 is running low, the elasticity is strengthened and the durability is improved, so that the adhesive tape 9' is always pressed against the bottom surface 2 until the very end. Furthermore, with the shape of this embodiment 4, by reducing the insertion index and creating space inside the clamping portion 10, the removal work can be performed by rolling it around, just like with a rolling type, without using the wrist.

[0027] [Claim 3] [Examples] Next, the cutter guard portion 2' provided to ensure a safe cutting edge for the tape cutter portion 6, taking advantage of the material's properties, is the embodiment 5 of [Claim 3].

[0028] <Comparative Example 4> In other words, Figure 10(a) shows that the inner edge of the bottom portion 2 is fitted with a metal tape cutter portion 6 that is fixed in place. Furthermore, a cutter guard portion 2' is provided at the tip of the bottom portion 2, extending beyond the cutting edge of the tape cutter portion 6, via a fold line. As shown in the diagram, the blade tip itself is not exposed. Furthermore, this fold line can also be a curved fold, allowing for adjustment of both elasticity and durability depending on the arch angle.

[0029] In contrast, in Figure 10(b), when the adhesive tape 9' is pulled out and cut by the tape cutter unit 6, the cutter guard unit 2' contacts the adhesive tape 9' before the blade tip, and the fold line retracts downwards, so the adhesive tape 9' is cut by the tape cutter unit 6 which is fixed in place. Furthermore, the elastic fold line simultaneously returns it to the state shown in Figure 10(a), so Example 5 is safe except for the cutting operation of the adhesive tape 9'.

[0030] As described above, the present invention can be used for cellophane tape, double-sided tape, paper tape without an adhesive surface, and also for stickers, label tapes, and the like. Furthermore, the material of the holder will not be limited to PP resin sheets with strong elasticity and hinge properties, taking into consideration recyclability, as well as paper and coated paper.

[0031] Furthermore, the various combinations of the present invention are freely chosen and are not limited to any of the embodiments.

[0032] Furthermore, since the sheet-like unfolded substrates of this invention can be stacked in any number of layers before assembly, they are not bulky and are convenient for storage, transportation, and sales.

[0033] Furthermore, since the unfolded circuit board is not punched out from the sheet-like backing, users can remove and fold the circuit board themselves, like with a plastic model kit, and use it as a tool. This makes it an adhesive tape holder that anyone can enjoy, and it also has an artistic appeal.

[0034] In summary, this unique, original, and extremely low-cost invention, which has undergone numerous improvements towards commercialization, will leverage its features to... Ideal for campaigns and promotional items for moving companies, pet shops, gas stations, and other businesses, adding a company logo or name to products ordered in bulk will make them useful in homes, offices, and cars, resulting in long-term advertising effects and significant sales volume.
