Description

Technical Field

[0001] This invention relates to a compact tape holder capable of mounting adhesive tape rolls with different inner diameters.

Background Art

[0002] Currently, standardized adhesive tape rolls with different inner diameters and a width of about 50 mm are commercially available, including those with a minimum diameter of 1 inch (about 2.5 cm), 1.5 inches (about 3.8 cm), 2 inches (about 5 cm), 2.5 inches (about 5.3 cm), and the mainstream large-diameter 3 inches (about 7.5 cm) adhesive tape rolls. However, tape cutters for handling them were used with tape cutters dedicated to their respective inner diameters, except for the following patent documents. The adhesive tape cutter capable of mounting adhesive tapes with different standardized inner diameters is the following patent document.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The adhesive tape cutter disclosed in this Patent Document 1 adjusts the outer diameter (maximum width) of the tape holding part divided into a fixed part and a movable part to enable mounting of adhesive tapes with different standardized inner diameters. That is, it can mount a large-diameter tape roll with a large inner diameter of the paper tube, and sometimes it can also mount and use a small-diameter tape roll with a small inner diameter. However, the adhesive tape cutter body is for mounting a large-diameter tape roll with a large inner diameter of the paper tube. Even if a tape roll with a small inner diameter of the paper tube can be mounted, the size of the cutter body remains large as before.

[0005] However, thinking in the opposite direction, a compact tape holder that uses a small tape cutter designed for small-diameter tape rolls, but can also accommodate large-diameter tape rolls, would be easy for anyone to use, not just children or women with small hands.

[0006] In other words, if you wind the same length of tape as a large-diameter tape roll onto a paper tube with a smaller inner diameter, the outer diameter of the tape roll becomes smaller, making it compact enough to fit in your hand even when mounted in a holder. Based on this, we provide a compact tape holder that allows for easy handling of various tape rolls, from small to large sizes, with standardized inner diameters, all in one unit. [Means for solving the problem]

[0007] Together with a pair of opposing side wall portions 3, a holder base 1 connecting the front ends of each side wall portion 3 and having a tape cutting portion 2 at its tip, and a roll spring plate 4 extending behind the holder base 1, A tape holder is provided in which a cylindrical roll holding portion 6 is integrally or separately provided on the inner surface of one or both of the side walls 3, and a tape guide portion 5 is provided on the inner surface of one or both of the side walls 3 between the roll holding portion 6 and the tape cutting portion 2, The roll spring plate 4 is provided on the holder base 1 at an angle that constantly presses against the roll holding portion 6 with a spring biasing force, The tape guide section 5 is provided as a rotating roller type, In addition to the cylindrical roll holding section 6, the tape roll was held at three points: the roll holding section 6, the roll spring plate 4, and the tape guide section 5.

[0008] Preferably, the roll holding section 6 is a double-cylinder rotating roller type, in which an outer cylinder 6B is detachably and rotatably placed over an inner cylinder 6A, which is either integral to or separate from the roll holding section 6.

[0009] Preferably, the inner surface of the roll resilience plate 4 is made of a smooth surface 4S that reduces friction.

[0010] Preferably, the roll holding portion 6 is provided with a gear-shaped outer cylinder 6B' whose outer surface is uneven, with the outer diameter of the outer cylinder 6B which is inscribed with the inner cylinder 6A.

[0011] Preferably, the roll spring plate 4 is provided with a tape tip fixing portion 7 at its rear end for fixing the tip of the adhesive tape, which has the tape cutting portion 2 as the reversing portion of the adhesive tape.

[0012] Preferably, the roll spring plate 4 is provided with a folding claw guide portion 8 on one or both sides of its inner surface, which grips and guides the tape roll with the spring biasing force it has while the claws are upright. [Effects of the Invention]

[0013] Previously, a separate holder was required for each different inner diameter, but with the above configuration, all standardized tape rolls can be mounted on a single unit, and it has also become more compact and easier for anyone to use. Furthermore, compared to Patent Document 1, the present invention is not only more compact, but also has a simpler structure, requires no adjustment of the tape holding part, and each tape roll can be used simply by fitting it into the roll holding part, just as in the conventional method. Furthermore, miniaturizing the currently prevalent large-diameter tape holders used for packaging can significantly reduce manufacturing costs, storage and display space, and transportation costs, including material costs.

Mode for Carrying Out the Invention

[0015] Hereinafter, the holder form with the same shape for carrying out the present invention will be described based on FIGS. 1 to 9. In addition, (a) and (b) are provided in each drawing to make it easier to understand.

Examples

[0016] First, FIGS. 1 to 3 are views showing the configuration of an integral U-shaped tape holder in which the side wall portions 3 on both sides of <Example 1> of the present invention do not expand.

[0017] First, FIG. 1(a) is [Claim 1] of the present invention. The inner cylinder 6A of the cylindrical roll holding portion 6 is a tape holder for, for example, 1 inch or 1.5 inches. It is a perspective view before mounting the adhesive tape roll (in the center of FIG. 1), and a holder base 1 provided with a tape cutting portion 2 for cutting the adhesive tape is provided at the tip.

[0018] Then, on the rear end surface of the holder base 1 provided with the tape cutting portion 2, a roll elastic plate 4 is provided on the holder base (1) at an angle such that it always approaches or contacts the roll holding portion 6, which is greatly different from the conventional purpose. In FIG. 1(b), the pressing force is also adjusted by the size of the constriction at the base and the thickness of the plate. Thus, when a tape roll is forcibly set between the roll release plate 4 and the roll holding section 6, an additional "pressing function" is added, which provides a stronger pressing force for release. (The effect of this "pressing function" will be described later.)

[0019] Furthermore, side walls 3 extending backward are located opposite each other on both sides of the holder base 1.

[0020] Furthermore, conventional tape guide sections 5 are provided on both sides of the inner surface of the side wall section 3, in the form of rotating rollers.

[0021] This is because the tape guide section 5 of the present invention differs significantly from conventional designs in that, in addition to serving as a tape guide and a tape tip return stopper, it also functions as a "stopper" to hold a tape roll with an inner diameter larger than the standard. Therefore, it is pressed down by the repulsive force of the elastic biasing of the roll spring plate 4, and an even greater force acts here when the tape is pulled out. As a result, unlike conventional designs, the adhesive tape cannot be pulled out smoothly.

[0022] To solve this problem, the tape guide section 5 is provided as a rotating roller type. In other words, the large frictional force applied to the "stopper" by the spring-releasing force of the roll spring plate 4 and the force when pulling out the tape is reduced as the roller rotates as the tape is pulled out. In this way, the rotation of the tape roll was made smoother, making it easier to pull out the tape.

[0023] The key to this invention lies in the combination of two components: a roll spring plate 4 that constantly has a "pressing function," and a rotating roller-type tape guide section 5 that reduces the large frictional force applied to the "stopper" resulting from this function.

[0024] With this combination, it becomes possible to hold the tape at three points. As shown in Figure 1(a), if the inner cylinder 6A is used for 1-inch tapes and the outer cylinder 6B is placed over it, it becomes a double cylinder, which can accommodate all tape rolls with inner diameters ranging from 1 inch to 1.5 inches, 2 inches, 2.5 inches, and 3 inches. Additionally, the 1.5-inch inner cylinder 6A makes tape extraction heavier than that of a rotating double cylinder and accommodates all tape rolls except for tape rolls with an inner diameter of 1 inch.

[0025] Furthermore, in the case of excessively strong resilience, such as when a new tape roll is replaced or when the outer diameter is large, the inner surface of the roll resilience plate 4 of [Claim 3] is made smooth by attaching a low-friction sheet film such as fluororesin or ultra-high molecular weight polyethylene material to the inner surface, thereby promoting the rotation of the tape roll in contact with it. Alternatively, the roll-type spring plate 4 may be provided by connecting a separate low-friction resin product instead of extending it. In this way, even with an overly strong "pressing function" on the tape roll, the tape is made easier to pull out due to "sliding friction."

[0026] In other words, the roll spring plate 4, which always has a "pressing function" and is smoothed, the tape guide section 5, which is a rotating roller, and the roll holding section 6, which has a double-cylindrical structure and is also a rotating roller, work together to reduce frictional resistance, making the rotation of the adhesive tape roll smoother and facilitating tape dispensing.

[0027] Furthermore, regarding the holding of tape rolls of different specifications according to the present invention, The smallest diameter tape roll A, with an inner diameter of 1 inch, is held using either the 1-inch inner cylinder 6A (Figure 1) or the inner cylinder joint 6A' as is, as the 1-inch inner cylinder A. Furthermore, the small-diameter tape roll B with an inner diameter of 1.5 inches can be used with either the inner cylinder 6A for 1.5 inches or the outer cylinder 6B (Figure 2). Furthermore, the medium-diameter tape roll C with an inner diameter of 2 inches, the medium-to-large diameter tape roll D with an inner diameter of 2.5 inches, and the large diameter tape roll E with an inner diameter of 3 inches are, Due to the strong propulsion biasing "pressing function" of this roll propulsion plate 4, The roll is held in place by three points: the roll spring plate 4, the roll holding section 6, and the tape guide section 5. (Figure 3)

[0028] Thus, in combination with the rotating roller type roll holding section 6, which has a double-cylinder structure in which the outer cylinder 6B is placed over the inner cylinder 6A, The combination of the roll spring plate 4, which always has a spring-pushing [pressing function], and the rotating roller type tape guide section 5, which solves the frictional force generated by it, is the most important configuration of the present invention, which has not been seen in the past.

[0029] And to describe some of the effects of this combination's "pressure function" in this invention, Traditionally, tape rolls would shrink in outer diameter over time, creating a gap between the roll and the release plate 4, so workers had to press down on them with their grip strength. However, in the present invention, the combination of the rotating roller type of the tape guide section 5 and the elastic biasing "pressing function," along with the smooth surface 4S of the roll elastic plate 4 described in [Claim 3] above, ensures that, unlike conventional methods, each tape roll is always subjected to strong pressure, making it easy to cut, preventing rattling, and allowing for easy handling until the very end of the tape.

[0030] Furthermore, this "pressing function" addresses the issue of the strong repulsive force of the resilience, preventing the roll resilience plate 4 from flapping around due to the adhesive force from the floor, clothing, etc., which come into contact with dirt, loose hair, etc., when the adhesive surface of the outer surface of the roll resilience plate 4 of [Claim 5] is used as an "adhesive tape cleaner".

[0031] Next, the folding claw guide section 8, provided on the inner surface of the roll spring plate 4 of [Claim 6], which is rotatable outward and guides the tape roll by the "pressing function" of the spring biasing force it has while the claws are upright, also accommodates the use of tape rolls of different widths. (See paragraphs

[0050] to

[0052] )

[0032] Furthermore, even in the case of a double-cylindrical shape, where a spacer 6S is not provided in the inner diameter of the outer cylinder 6B, the inner diameter of the outer cylinder 6B rotates while partially contacting the outer diameter of the inner cylinder 6A due to the "pressing function" caused by the elastic biasing force, so a spacer 6S is not required. (See paragraph

[0055] )

[0033] Next, regarding the roll holding section 6 in Figure 1(a) of Example 1, in order to attach an adhesive tape roll to a conventional, non-expandable, integrated U-shaped mini tape holder, the roll holding sections provided on both sides, which are narrowed inward at the rear, are opened to both sides against the elastic force to attach the roll. Therefore, to facilitate attachment and detachment, shallow, short cylindrical roll holding sections were provided on both sides, facing each other.

[0034] While 6A' can be used as an inner cylinder, in particular with the roll holding section 6 when holding at three points according to the present invention, if the tape holder is gripped too tightly when pulling the adhesive tape out of the tape holder or when cutting the tape, the side wall section 3 narrows, pressing down on both sides of the tape roll, stopping its rotation and preventing it from being pulled out.

[0035] To address this, in <Embodiment 1> of the present invention, as shown in Figure 1, holes at both ends of the cylindrical inner cylinder 6A or protrusions at both ends are provided at both ends of the inner cylinder 6A to fit into the inner cylinder joint 6A' provided opposite the side wall portions 3, thereby creating a "shortening stopper". In other words, it is a mechanism that does not shorten the distance between the two side sections 3. (Also, the "shortening stop" can be achieved by fitting the protrusions at both ends of the inner cylinder 6A into the perforated inner cylinder joint 6A' (the front side wall 3 in the diagram) which is provided opposite to both side wall portions 3.)

[0036] Figure 1(b) is a schematic cross-sectional view of only the tape holder, which is provided in contact with the roll holding portion 6 of the inner cylinder A fitted into the inner cylinder joint 6A', where the roll spring plate 4 is located.

[0037] Next, Figure 2(a) shows a configuration in which a small-diameter tape roll B is mounted on a roll holding section 6, which has a perforated inner cylinder joint 6A' provided by covering the inner cylinder 6A for 1 inch diameters in Figure 1 with an outer cylinder 6B. (The center of Figure 2 shows different types of outer cylinders 6B, which will be described later in paragraph

[0054] and subsequent paragraphs.) Furthermore, the rotating roller here is a separate, single unit, which is the tape guide section 5 fitted into opposing notches at the top of the side wall sections 3.

[0038] Furthermore, Figure 2(b) shows a schematic cross-sectional view of the small-diameter tape roll B, where the roll holding section 6, which has a double-cylinder structure formed by placing the outer cylinder 6B over the inner cylinder 6A, is mounted, resulting in the roll's elastic biasing plate 4, which has increased restoring force, pressing down more strongly.

[0039] Next, Figure 3(a) is a diagram showing a large-diameter tape roll E mounted on the mini tape holder of the present invention. Furthermore, the tape guide sections 5 on both sides of the inner surface of the side wall section 3 receive the force exerted by the elastic bias of the repulsive force of the roll elastic plate 4 as the large-diameter tape roll E is pushed, and act as a "stopper" for it.

[0040] Furthermore, a feature of the present invention is that the tape roll E, which has a standardized inner diameter greater than or equal to the outer diameter of the roll holding portion 6 of the inner cylinder 6A or outer cylinder 6B, which are provided as an integral part or separately, is held at three points. Next, Figure 3(b) is a schematic cross-sectional view showing that the large-diameter tape roll E is held at three points. In other words, the first point is the roll spring plate 4 labeled I in the figure, the second point is the roll holding part 6 labeled II in the figure, and the third point is the tape guide part 5 labeled III in the figure, which are schematic cross-sectional views showing the holding at these three points.

[0041] Thus, the present invention reduces friction at all three contact surfaces by using the rotating rollers II and III to reduce "rolling friction," which is a major element in friction reduction, and the sliding surface 4S of I to reduce "sliding friction," and by having the roll spring plate 4 constantly press against the surface. Not only can all standardized tape rolls be used with this single unit, but the tape holder has also been made more compact. [Examples]

[0042] Next, Figure 4(a) is a diagram of <Example 2> in which one side wall portion 3 is a tape holder that unfolds. Alternatively, it could be a single-sided open hinge without a separate cover (cap).

[0043] Furthermore, the tape guide section 5 here is a single rotating roller on one side of the side wall section 3 that assembles the unfolding plate, and then fits it into place on the other side. Furthermore, unlike in <Example 1>, the roll holding portion 6 of the inner cylinder 6A does not shrink in its structure, so a shortening stopper is not necessary. Furthermore, by cutting grooves into the outer surface of the rotating roller of the tape guide section 5, the grooves function effectively as a stopper, reducing friction, and also as a tape return stopper, as the contact area becomes smaller, making it less likely for the tape to stick.

[0044] Furthermore, Figure 4(a) shows that the inner cylinder 6A of the roll holding section 6 is longer than one side of the side wall section 3, with a concave cylinder protruding from its end, and the other side is shorter, with a convex cylinder protruding from its end, which fits into the inner cylinder in a spigot-like manner. Furthermore, in <Example 1>, in order to attach the tape roll, the roll holding portion 6 of the inner cylinder 6A and the outer cylinder 6B were inserted into the inner diameter of the tape roll while opening the side walls 3 on both sides. Here, the tape roll is inserted into the long, concave cylinder on one side, and then the shorter, convex cylinder is joined to it in a spigot-like fashion.

[0045] Furthermore, Figure 4(b) shows the configuration just before assembly (joining) of the single-piece, rotating roller type tape guide section 5 and the inner cylinder (6A) of the 1-inch tape roll shown in Figure 4(a), with the outer cylinder 6B placed over it.

[0046] Also, similar to Example 1, by placing the outer cylinder 6B over the inner cylinder 6A for 1 inch shown in Figure 4(a), a double cylinder is formed as shown in Figure 4(b), which can accommodate all tape rolls with inner diameters ranging from 1 inch to 3 inches. Furthermore, the inner cylinder 6A for 1.5-inch tape shown in Figure 4(a) is heavier to pull out than the rotating double cylinder and accommodates all tape rolls except for tape rolls with an inner diameter of 1 inch. [Examples]

[0047] Next, Figure 5(a) shows the configuration of <Example 3>, where the side walls 3 on both sides are unfolded and assembled, and the unfolding plate is used to form the tape holder.

[0048] Furthermore, Figure 5(a) shows the configuration of the adhesive tape cleaner according to [Claim 4]. As shown in the diagram, this is also a diagram of the form of an extendable plate in which a hinge-type tape tip fixing part 7, which is attached and fixed to the outer surface of the rear end of the roll spring plate 4, is integrally extended for use as an adhesive tape cleaner.

[0049] Figure 5(b) shows the assembled structure with the outer cylinder 6B placed over the unfolded plate shown in Figure 5(a). Furthermore, by dividing the tape guide section 5 as shown in the diagram, friction is further reduced, resulting in smoother rotation. Furthermore, the roll spring plate 4 in the above-mentioned <Example 1> and <Example 2> may be made into a separate unit, provided with a hinged tape end fixing part (7) such as a PP resin sheet or clip, in order to address the issue in [Claim 5].

[0050] Also, here, as in Example 1, by placing the outer cylinder 6B over the inner cylinder 6A for 1 inch shown in Figure 5(a), a double cylinder is formed as shown in Figure 5(b), which can accommodate all tape rolls with inner diameters ranging from 1 inch to 3 inches. Furthermore, the 1.5-inch inner cylinder 6A makes tape extraction heavier than the rotating double cylinder and accommodates all tape rolls except for tape rolls with an inner diameter of 1 inch.

[0051] Furthermore, as shown in Figure 5(a), the folding claw guide portion (8) of [Claim 6] is provided on one side of the roll spring plate 4, which will be explained in detail in the following Figures 6(a) and 6(b).

[0052] The following Figure 6 shows the above-mentioned <Example 3> with all of claims 1 to 6 of the present invention provided on the tape holder of the unfolding plate. First, Figure 6(a) shows the configuration of [Claim 6] that accommodates different widths of tape rolls. In Figure 6(a), two folding claw guide sections (8) are provided on the inner surface of the roll spring plate 4, which grip and guide the tape roll with the spring biasing force that the claws have while they are upright. In other words, to allow narrow adhesive tape rolls of different widths to be held in place, folding claw guide sections 8, which can rotate outward on the inner surface of the roll release plate 4, are provided facing each other here.

[0053] Furthermore, the schematic cross-sectional view in Figure 6(b) shows a narrow adhesive tape roll with its width narrow, where the usual folded claw-shaped guide sections are pushed outward and clamped with elastic biasing force. This mechanism, combined with the repulsive force of the roll elastic plate 4, clamps the narrow adhesive tape roll from all directions, preventing lateral displacement. (Also, Figure 5(a) shows a diagram where, when there is no margin in the width and it is not possible to install them on opposite sides, one side wall 3 is utilized and the installation is carried out on one side.) Furthermore, a separate tape tip fixing portion 7 may be provided on the outer surface of the roll-type propellant plate 4, and this folding claw guide portion 8 may be provided on the inner surface as a single sheet, which can then be folded in half and attached to both sides.

[0054] Figure 6(b) shows the small-diameter tape roll B mounted on the small-diameter tape roll, with the outer cylinder 6B, which has a spacer, placed over the inner cylinder 6A of the small-diameter tape roll holder. Furthermore, the folding claw guide portion 8 of [Claim 6] is shown in a schematic cross-sectional view in an upright position.

[0055] Next, regarding the double-cylinder outer cylinder 6B of the present invention [Claim 2], The different types of outer cylinders 6B, as shown in the center of Figure 2 and described in paragraph

[0036] , will now be discussed. First, in Figure 6(b), there is a thick-walled outer cylinder 6B on the upper right, and furthermore, on the left side of the outer cylinder 6B in the center of Figure 2. Next, the adjacent outer cylinder 6B has a spacer 6S to ensure a gap in its inner diameter. (Located in the lower center of Figure 6, and also in the center of the outer cylinder 6B in Figure 2.) Furthermore, some versions have a gear-shaped spacer 6S attached to the outer diameter of the outer cylinder 6B. (In Figure 6(b), it is in the upper center, and furthermore, on the right side of the outer cylinder 6B in the center of Figure 2.) In other words, if the roll holding section 6 has a double concentric cylindrical shape, Besides the thick-walled outer cylinder 6B, the outer cylinder 6B needed to be thicker in order to fit the outer cylinder 6B over the inner cylinder 6A and make them inscribed inside each other. To enclose it in a cylinder of normal thickness (approximately 2 mm), a considerable amount of space would be created. To solve this problem, a spacer 6S was provided to secure space. [Examples]

[0056] <Example 4> is a double cylinder in which a spacer 6S is not provided in the inner diameter of the outer cylinder 6B of normal thickness. In other words, as shown in the upper center of Figure 6 and the upper left of Figure 6(b), the outer cylinder 6B does not have a spacer 6S in its inner diameter, resulting in a double eccentric cylindrical shape. As mentioned several times above, the strong repulsive force of the roll spring plate 4 provides a "pressing function," causing the outer diameter of the inner cylinder 6A to rotate while partially contacting the inner diameter of the outer cylinder 6B, thus eliminating the need for a spacer 6S. Furthermore, the increased space due to the eccentricity allows for the holding of thicker tape rolls. [Examples]

[0057] Next, Figure 7(a) shows that among the types of outer cylinder 6B, the outer surface is gear-shaped, and the outer cylinder 6B' is <Example 5>. In the present invention, the spacer 6S of the roll holding section 6 was provided on the inner diameter of the outer cylinder 6B, but in <Example 5> of [Claim 4], it was provided on the outer diameter, which is the outer circumferential surface, as shown in Figure 7. In other words, the outer cylinder 6B, which is formed by rotatably stacking the inner cylinder 6A in contact with the outer cylinder 6B, has a gear-shaped spacer 6S attached to its outer diameter, resulting in an outer diameter of slightly less than 1.5 inches. This design increases the in-contact area compared to one where the spacer 6S is attached to the inner diameter, and also improves the effect of the deep groove, resulting in a functionally beautiful design. Furthermore, Figure 7(b) is a schematic cross-sectional view showing a small-diameter tape roll B set in a holder on the outer cylinder 6B' of the gear-shaped outer cylinder.

[0058] Alternatively, a thick-walled outer cylinder 6B with a gear-shaped outer cylinder and deep grooves can be used, or a gear-shaped rubber tube can be fitted over it.

[0059] Furthermore, when using the smallest diameter tape roll A with an inner diameter of 1 inch, the double cylinder of the present invention is used by removing the outer cylinder 6B that is covering it and setting it on the inner cylinder 6A.

[0060] In addition, paragraphs

[0028] to

[0031] explained the advantages of the "pressing function" using resilient biasing, but it can also be used as a mini holder for double-sided tape rolls, paper tape rolls without adhesive surfaces, PP and PE film rolls for packaging, and even for stickers and label tapes.

[0061] Furthermore, the various combinations of the present invention are freely chosen and are not limited to any of the embodiments.

[0062] Next, Figure 8(a) illustrates how to use the present invention as an adhesive tape cutter. Once you've pulled out the adhesive tape to your desired length, cut it at the tape cutting section 2 and use it. Also, when directly attaching the adhesive tape during the packing process of cardboard boxes, as shown in Figure 8(b), first pull out the adhesive tape, and while applying it, stop at the point where you want to cut it, then place the adhesive tape against the tape cutting section 2 and cut it.

[0063] Next, Figure 9(a) explains how to set up and use an adhesive tape cleaner equipped with a tape tip fixing part 7 of the type shown in Figure 5(a) at the rear end of the roll spring plate 4. (Note that the tape end fixing part 7 in Figure 6(a) is a type that also has a locking mechanism, but it is not limited to this type as long as the tape end can be fixed.)

[0064] First, after pulling out the adhesive tape in the same way as with the adhesive tape cutter described above, instead of cutting it at the tape cutting section 2, as shown in Figure 9(a), the adhesive tape is reversed at the tape cutting section 2 and pulled out along the roll of elastic plate 4. Furthermore, as shown in Figure 9(b), the tip of the adhesive tape is sandwiched between the hinge of the tape tip fixing part 7 provided at the rear end and then attached and secured. If there is any slack in the adhesive tape, reverse the tape roll to remove the slack.

[0065] Furthermore, as shown in Figure 9(b), with the adhesive side of the roll spring plate 4 facing downwards, press the adhesive side against the debris and loose hair to attach it. Once you're finished, pull the tab at the tip to release the adhesive surface, fold it in half to seal in any debris or loose hair, then cut it at the tape cutting section 2 and discard it.
