Description

[Technical field]

[0001] The present invention relates to an adhesive tape holder. [Background technology]

[0002] The applicant has previously attempted to create a unique foldable adhesive tape holder that can be used as an adhesive tape tool by folding a colorful and durable PP resin sheet like origami, and can also be used as an artistic adhesive tape cutter or adhesive tape cleaner. The applicant has disclosed the following patent documents regarding this foldable adhesive tape holder. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6919096 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the foldable adhesive tape holder described in Patent Document 1 above, the elasticity of the tape support legs that support the adhesive tape roll weakens over time, reducing the pressing function. As a result, when used to cut adhesive tape or as an adhesive cleaner, the adhesive tape roll becomes loose and difficult to handle. Furthermore, adhesive tape cleaners have a problem in that the adhesive surface at the bottom is narrow, so that when it comes to removing a large amount of debris or hair, the cleaner must be set up and removed repeatedly. To provide a foldable adhesive tape holder which solves these problems and is superior in both functionality and design and has a beautiful functional appearance. [Means for solving the problem]

[0005] A foldable adhesive tape holder comprising a top surface portion (1), tape support legs (5), (5) provided at both longitudinal ends of the top surface portion (1), a retaining lid portion (4) provided at one lateral end of the top surface portion (1), a bottom surface portion (2) provided on the opposite side of the top surface portion (1), and side surfaces (3), (3) provided at both lateral ends of the bottom surface portion (2) in the lateral direction, which constitute a roll holding portion (A) for holding an adhesive tape roll (9) in a cylindrical shape, The tape support legs (5), (5) are provided opposite each other via fold lines at both longitudinal ends of the top surface portion (1), and the retaining lid portion (4) and the side surface portion (3) are provided opposite each other via fold lines at both transverse ends. In addition, each of the four fold lines is folded in a curved line, thereby strengthening the top surface portion (1) and enhancing the elasticity and durability of the tape support legs (5), (5).

[0006] Preferably, the support leg connection 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 an inserted hand.

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

[0007] In the present invention, the folding line of the tape support leg, which is located opposite the upper surface of Patent Document 1, is changed from a straight mountain fold to a curved fold with an arch structure that adds an extra layer of elastic force, thereby strengthening the elastic force and improving durability. In this way, the problem was solved by the simple means of changing the conventional folding method, without adding any new parts. Furthermore, by changing the arch angle, it is possible to provide a tape holder with an appropriate elastic force strength adjusted to suit each tape roll, which was not possible with conventional straight-line folding. Furthermore, the problem of an adhesive tape cleaner having a narrow adhesive surface has been solved by providing a clamping part 10 that connects both ends of the tape support legs, which have enhanced elasticity and improved durability, in an arch shape, thereby making the entire circumference of the tape holder an adhesive surface.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In addition, (a) and (b) are provided in each drawing to make it easier to understand. EXAMPLES

[0010] First, as shown in FIG. 1, a foldable adhesive tape holder having an adhesive tape cutter function is Example 1. FIG. 1(a) is a perspective view showing a roll holding portion A that holds an adhesive tape roll 9 in a cylindrical shape, which is made up of tape support legs 5, 5 that are curved in an arch shape to apply a single layer of elastic force, a top portion 1, a retaining lid portion 4, and side portions 3, 3 provided on both ends of a bottom portion 2.

[0011] In addition, the figure shows a tape cutter specifically for craft tapes, but for transparent PP adhesive tapes and the like, which can become difficult to peel off if the tip of the tape rolls back and sticks due to a tendency to curl or static electricity, a backstop is required, so in this case, the tape guide section 7, which also functions as a backstop, as in Example 2 can be provided together with the tape cutter section 6. Furthermore, FIG. 1(b) is also a development in which curved fold lines are provided on each side of the upper surface portion 1. EXAMPLES

[0012] Next, as shown in FIG. 2, a foldable adhesive tape holder having a dual function of the adhesive cutter of the first embodiment and an adhesive tape cleaner is the second embodiment. In other words, the oblique view of Figure 2(a) shows 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 on the opposite side of the tape guide portion 7 which turns the tape over and pulls it out along the bottom portion 2 to fix the adhesive surface at the tip, thereby allowing it to be used as an adhesive tape cleaner. Furthermore, FIG. 2b is also a development in which curved fold lines are provided on each side of the top surface portion 1.

[0013] <Comparative Example 1> Next, FIG. 3 shows Comparative Example 1 with the conventional Patent Document 1. In this way, in the perspective view of FIG. 3(a), both ends of the upper surface portion 1 in the short direction are curved, The tape support legs 5, 5 at both ends in the longitudinal direction are linearly folded in a mountain fold. However, in the present invention shown in Figure 3(b), both longitudinal ends of the upper surface portion 1 are also curved and folded with an arch structure that adds an additional layer of elastic force, thereby solving the problem of increasing the elastic force of the tape support legs 5, 5 as well as improving durability.

[0014] [Claim 2] EXAMPLES Furthermore, the dual-use adhesive tape cleaner of Example 2 of the present invention had a problem in that the adhesive surface of the bottom portion 2 was narrow, so that repeated setting and removal operations were required when dealing with a large amount of debris or hair. To solve this problem, we made the entire circumference adhesive, just like the rolling type, which is currently the mainstream adhesive tape cleaner, which removes debris and hair by rolling it around. In addition, the adhesive tape cutter can also be used as an adhesive cleaner because the entire circumference of the tape holder is made adhesive, which has been solved with the tentative name "Ouroboros-style adhesive tape cleaner."

[0015] The present invention according to the third embodiment will be described with reference to FIG. 4 using the adhesive tape cutter according to the first embodiment. Figure 4(a) is a diagram showing the configuration of the tape cutter unit 6 which turns the adhesive tape 9' pulled out from the roll holding unit A, turning the tape 9' over at the inverted portion so that the adhesive surface faces outwards, runs around the bottom unit 2, and then returns to its original state, and attaches and fixes the tip of the adhesive tape 9' to the adhesive surface of the inverted portion where it started. Thus, in the third embodiment of the present invention, the reversing portion and the fixing portion are in the same place.

[0016] In other words, the third embodiment of the present invention is similar to the Ouroboros ring used in ancient Greece in Fig. 4(b). The symbol of a snake biting and swallowing its own tail to form a circle is an easy-to-understand image to explain the configuration of this invention, tentatively named "Ouroboros-style adhesive tape cleaner."

[0017] FIG. 4(a) shows a foldable adhesive tape holder having an arch-shaped clamping portion (10) according to claim 2, which is embodiment 3. In other words, like the "handle" of the rolling-type adhesive tape cleaner described above, the tape support legs 5, 5 described in [Claim 2], which enable setting and removal operations without coming into contact with any of the adhesive surfaces, are provided with a connected clamping portion 10 so that the holder can be clamped with the arched internal fingers.

[0018] <Comparative Example 2> Next, FIG. 5(a) is a development view of the tape support legs 5, 5' at the ends of the tape support legs 5, 5, which are connected in the center to form an arch shape, as described in claim 2. FIG. 5(b) is a development view showing supporting leg connecting parts 5', 5' connected on either side to form an arch shape. Furthermore, the support leg connection part 5' on the hook side is provided with a function for adjusting the arch length.

[0019] Next, FIG. 6(a) is a diagram showing a state in which an adhesive tape roll 9 is mounted inside the holder assembled by folding the holder shown in FIG. 5(a). FIG. 6(b) is a diagram showing the shape of the adhesive surface all around, in which the adhesive surface at the tip is folded back to make it easier to set up and remove the tape without touching the adhesive surface when pulling out the adhesive tape 9', and a "knob" is made in advance and fixed to the original adhesive surface.

[0020] Next, FIG. 7 will be used to explain the gripping portion 10 of the present invention which is detachable and does not need to be gripped, and which corresponds to a "handle" of the rolling type adhesive tape cleaner. In the figure, a gripping portion 10 is provided that frictionally engages with the fingers of an inserted hand, allowing the thumb to be used freely to perform setting and removal operations without contacting the entire adhesive surface of the holder. FIG. 7(a) shows this, in which several fingers other than the thumb are inserted closely inside the arch, and the inserted fingers frictionally engage between the inner arch surface of tape support leg 5 and the outer surface of top portion 1 to clamp the holder.

[0021] Furthermore, FIG. 7(b) shows the state in which the setting operation is completed and the removal operation is performed without using the thumb and while the holder is held firmly enough that it will not fall even if pointed downward. For large amounts of debris or hair, the entire circumference is sticky so you can start from anywhere, but start with the palm of your hand and gradually press down, then turn your hand over and use your wrist to adjust the pressure and remove the debris from anywhere.

[0022] When it is desired to change to a new adhesive surface, the tab is removed from the adhesive surface and folded in half to seal in any debris or loose hair on the adhesive surface, and the tape is cut by the tape cutter section 6 and discarded. In this way, the sticky side is folded in half and thrown away, so the dirty sticky side does not stick to the opening of a trash can, etc. EXAMPLES

[0023] Next, Example 4 is a specialized, roughly circular holder of the present invention, tentatively named an "Ouroboros-style adhesive tape cleaner," which has an adhesive surface all around, just like the currently mainstream rolling type. Here, we will explain using a chart in the order of (1) to (4). First, FIG. 8(a) shows a development board of a specialized embodiment of the present invention tentatively named “Ouroboros-style adhesive tape cleaner” with an adhesive surface all around.

[0024] Next, FIG. 8(b) is a diagram showing the state in which the developed substrate is being folded.

[0025] <Comparative Example 3> Next, FIG. 9(a) is a diagram showing a state in which a new adhesive tape roll 9 is pressed against the bottom portion 2 by the tape support legs 5, 5 on which a new adhesive tape roll 9 is mounted, as shown in FIG. In addition, the tape support legs 5, 5 are integrated by connecting both ends and work together, so that the load is not biased between them, and the durability is further improved.

[0026] Next, FIG. 9(b) is a diagram showing a configuration in which, due to the strengthened elastic force and improved durability, the adhesive tape 9' is always pressed against the bottom portion 2 until the very end, even when there is only a little adhesive tape roll 9 remaining. Furthermore, in the shape of this embodiment 4, if the insertion index is reduced to open up the inside of the clamping portion 10, the removal work can be performed by rolling it around like the rolling type without using the wrist.

[0027] [Claim 3] EXAMPLES Next, in order to ensure a safe cutting edge of the tape cutter section 6, a cutter guard section 2' is provided by taking advantage of the characteristics of the material, which is the fifth embodiment of [Claim 3].

[0028] <Comparative Example 4> That is, in FIG. 10(a), a metal tape cutter section 6 is provided and fixed to the inner end of the bottom section 2. Furthermore, a cutter guard portion 2' that extends beyond the cutting edge of the tape cutter portion 6 is provided at the tip of the bottom portion 2 via a folding line portion. As shown in the figure, the cutting edge itself is not exposed. Moreover, the fold line may also be curved so that the elasticity and durability can be adjusted by changing the arch angle.

[0029] In contrast, in FIG. 10(b), when the adhesive tape 9' is pulled out and cut with the tape cutter section 6, the cutter guard section 2' comes into contact with the adhesive tape 9' before the cutting edge, and the fold line section retracts downward, so that the adhesive tape 9' is cut by the tape cutter section 6 which is fixed over it. At the same time, the folding line portion has elasticity, so that the folding line returns to the state shown in FIG. 10(a), and therefore, in the fifth embodiment, the folding line portion is safe except for the operation of cutting 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 side, and also for stickers and label tape. Furthermore, the material of the holder is not limited to PP resin sheets with strong elasticity and hinge properties, and can be paper or coated paper, taking into consideration recyclability.

[0031] Furthermore, the various combinations of the present invention are free and are not limited to the respective embodiments.

[0032] Furthermore, in the present invention, the sheet-like unfoldable substrate before assembly can be stacked any number of times, so it does not take up much space and is convenient for storage, transportation, and sale.

[0033] Furthermore, instead of punching out the expandable board from the sheet-like mount, the user can remove the expandable board and fold it up themselves, just like a plastic model, to use it as a tool, making this an artistic adhesive tape holder that anyone can enjoy.

[0034] As described above, this invention has been improved many times in preparation for commercialization, and is unique, original, and extremely inexpensive. By utilizing these characteristics, They are ideal for campaigns and promotional items for moving companies, pet shops, gas stations, etc., and if you can print your company logo or name on the products sold in lots, they will come in handy in the home, office, and even in the car, so you can expect long-term advertising effects and significant sales.
