Description

[Technical Field]

[0001] The present invention relates to a compact tape holder that can accommodate adhesive tape rolls with different inner diameters. [Background technology]

[0002] Currently, adhesive tape rolls with a standardized width of approximately 50 mm and different inner diameters are commercially available, including the smallest diameter of 1 inch (approximately 2.5 cm), 1.5 inches (approximately 3.8 cm), 2 inches (approximately 5 cm), 2.5 inches (approximately 5.3 cm), and the mainstream large diameter of 3 inches (approximately 7.5 cm). However, with the exception of the patent documents listed below, tape cutters dedicated to the respective inner diameters have been used to handle these. The adhesive tape cutter that can accommodate adhesive tapes of different standardized inner diameters is described in the following patent document. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-149283 A Summary of the Invention [Problem to be solved by the invention]

[0004] The adhesive tape cutter disclosed in Patent Document 1 adjusts the outer diameter (maximum width) of a tape holding portion divided into a fixed portion and a movable portion, making it possible to attach adhesive tapes with different standardized inner diameters. That is, a large diameter tape roll with a large inner diameter of the paper core can be mounted, and sometimes a small diameter tape roll with a small inner diameter can also be mounted and used. However, the adhesive tape cutter body is designed to accommodate a large diameter tape roll with a large inner diameter paper core, and even if a tape roll with a small inner diameter paper core can be attached, the size of the cutter body remains large as before.

[0005] However, if we think in the opposite way and use a small tape cutter that is usually suited to small diameter tape rolls with a small inner diameter, but also have a compact tape holder that can sometimes be used with large diameter tape rolls with a large inner diameter, it will be easy to use for anyone, not just children and women with small hands.

[0006] In other words, if the same length of tape as a large diameter roll is wound onto a paper tube with a small inner diameter, the outer diameter of the tape roll will be small, and even when attached to the holder, it will be compact enough to fit in your hand. Based on this, we provide a compact tape holder that can be easily used to handle various tape rolls with different standardized inner diameters, from small to large sizes. [Means for solving the problem]

[0007] A pair of opposing side walls 3, a holder base 1 having a tape cutting section 2 at its tip that connects the front of each side wall 3, and a roll spring plate 4 extending behind the holder base 1, A tape holder in which a cylindrical roll holding portion 6 is provided integrally or separately on the inner surface of one or both of the side wall portions 3, and a tape guide portion 5 is provided on the inner surface of one or both of the side wall portions 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 always presses the roll holding portion 6 with a spring force, and The tape guide unit 5 is provided as a rotary roller type, The tape roll was held at three points: the cylindrical roll holding portion 6, the roll spring plate 4, and the tape guide portion 5.

[0008] Preferably, the roll holding part 6 is a rotating roller type having a double cylindrical structure in which an outer cylinder 6B is detachably and rotatably placed over an inner cylinder 6A provided integrally with or separately from the roll holding part 6.

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

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

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

[0012] Preferably, the roll spring plate 4 has a folding claw guide portion 8 on one or both of its inner surfaces, which is provided while the claw is standing and which pinches and guides the tape roll by the spring force. [Effects of the Invention]

[0013] Previously, a dedicated holder was required for each different inner diameter, but with the above configuration, all standardized tape rolls can be attached to one unit, and it is also compact and easy for anyone to use. Furthermore, compared to Patent Document 1, the present invention is not only more compact, but also has a simpler configuration, and there is no need to adjust the tape holding section; each tape roll can be used simply by fitting it into the roll holding section, just as in the conventional case. Furthermore, by making the large-diameter tape holders currently used for packing more compact, it is possible to significantly reduce manufacturing costs, including material costs, storage and display space, and transportation costs.

[0015] Hereinafter, holders of the same shape for carrying out 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. [Example]

[0016] First, FIGS. 1 to 3 show the structure of an integrated U-shaped tape holder in which both side wall portions 3 do not unfold, according to a first embodiment of the present invention.

[0017] First, Figure 1(a) is [Claim 1] of the present invention, and shows the inner tube 6A of the cylindrical roll holding portion 6 as a tape holder for, for example, 1 inch or 1.5 inch tape (center of Figure 1), before an adhesive tape roll is attached, and at the tip is provided a holder base 1 with a tape cutting portion 2 for cutting the adhesive tape.

[0018] At the rear end surface of the holder base 1 where the tape cutting section 2 is provided, a roll spring plate 4 is provided at an angle to the holder base 1 so that it is always close to or in contact with the roll holding section 6, which is quite different from the conventional purpose. (Fig. 1(b)) The pressing force can also be adjusted by changing the size of the groove at the base and the thickness of the plate. In this way, when the tape roll is forcibly set between the roll spring plate 4 and the roll holding part 6, a "pressing function" of a spring force that presses the tape roll even more strongly is added (the effect of this "pressing function" will be described later).

[0019] Side walls 3 extend rearward from both side surfaces of the holder base 1 so as to face each other.

[0020] Furthermore, on both sides of the inner surface of the side wall portion 3, conventional tape guide portions 5 are provided as rotating rollers.

[0021] This is because the tape guide section 5 of the present invention has a significantly different purpose from the conventional one. In addition to being a tape guide and a tape end return stopper, it also serves as a "stopper" to hold a tape roll with an inner diameter larger than the standard. As a result, it is pressed down by the repulsive force of the spring bias of the roll spring plate 4, and when the tape is pulled out, an even greater force acts here, so unlike the conventional one, 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 resilient bias of the roll resilient plate 4 and the force when the tape is pulled out is reduced by the roller rotating when the tape is pulled out. In this way, the rotation of the tape roll is smooth, making it easy to pull out the tape.

[0023] The key to this invention is the combination of the roll spring plate 4, which always has a "pressing function," and the rotating roller type tape guide unit 5, which reduces the large frictional force applied to the "stopper" that results from this.

[0024] The combination of these two makes it possible to hold the tape at three points. In Figure 1(a), if the inner cylinder 6A is for 1 inch and the outer cylinder 6B is placed over it, it becomes a double cylinder, and can accommodate all tape rolls with inner diameters ranging from 1 inch to 1.5 inches, 2 inches, 2.5 inches, and 3 inches. In addition, the inner cylinder 6A for 1.5 inches is heavier when pulling out the tape than a rotating double cylinder, and can accommodate all tape rolls except for tape rolls with an inner diameter of 1 inch.

[0025] In addition, to cope with excessively strong spring force, such as when replacing a new tape roll or when the outer diameter is large, the inner surface of the roll spring plate 4 (Claim 3) is provided with a smooth surface 6S, in which a low-friction sheet film made of fluororesin or ultra-high molecular weight polyethylene material is attached, thereby promoting the rotation of the tape roll in contact with it. Also, the roll spring plate 4 may be provided by connecting a separate low-friction resin product instead of extending it. In this way, even if the "pressing function" on the tape roll is too strong, the "sliding friction" makes it easier to pull out the tape when it is pulled out.

[0026] In other words, the three parts of the smoothed roll spring plate 4 that always has a "pressing function," the tape guide part 5 that is a rotating roller, and the roll holding part 6 that has a double cylindrical structure and is also a rotating roller work together to reduce frictional resistance, smooth the rotation of the adhesive tape roll, and make it easy to pull out the tape.

[0027] In addition, regarding the holding of tape rolls of different specifications of the present invention, The smallest diameter tape roll A, with an inner diameter of 1 inch, is held in the inner tube 6A for 1 inch (Fig. 1) or the inner tube joint 6A' is held as it is as the inner tube A for 1 inch. In addition, the small diameter tape roll B with an inner diameter of 1.5 inches is used for the inner cylinder 6A for 1.5 inches or the outer cylinder 6B (Figure 2). Furthermore, a medium diameter tape roll C with an inner diameter of 2 inches, a medium to large diameter tape roll D with an inner diameter of 2.5 inches, and a large diameter tape roll E with an inner diameter of 3 inches are The strong resilience of the roll spring plate 4 provides a "pressing function" The roll is held in place by three points: the roll spring plate 4, the roll holder 6, and the tape guide 5 (Fig. 3).

[0028] In this way, in combination with the double-cylinder structure of the rotating roller type roll holder 6, in which the inner cylinder 6A is covered with the outer cylinder 6B, The most important feature of this invention is the combination of the roll spring plate 4, which always has a spring-loaded [pressing function], and the rotating roller type tape guide section 5, which solves the frictional force that arises from it. This combination was not previously available.

[0029] The effects of this combined "pressing function" in the present invention are as follows: Conventionally, the outer diameter of a tape roll becomes smaller as it is used, and a gap opens up between the roll and the spring plate 4, so work has been performed by pressing down with grip strength. However, in the present invention, the "pressing function" of the resilient bias combined with the rotating roller type of the tape guide section 5 and the smooth surface 4S of the roll resilient plate 4 described above in [Claim 3] always maintains a strong pressure on each tape roll, unlike conventional methods, making it easy to cut, without rattle, and easy to handle right to the end of the tape.

[0030] This "pressing function" is achieved by the strong repulsive force of the spring force, which prevents the roll spring plate 4 from flapping about due to the adhesive force from the floor, clothes, etc. that it comes into contact with along with dirt and hair when the adhesive surface on the outer surface of the roll spring plate 4 of [Claim 5] is used as an "adhesive tape cleaner."

[0031] Next, the folding claw guide portion 8 provided on the inner surface of the roll spring plate 4 in claim 6 is rotatable outward and guides the tape roll by pinching it with the "pressing function" of the spring force of the claws when they are standing, and is also compatible with tape rolls of different widths (see paragraphs

[0050] to

[0052] ).

[0032] Furthermore, even in the case of a double cylindrical shape with a double eccentric cylinder shape in which a spacer 6S is not provided on the inner diameter of the outer cylinder 6B, the "pressing function" due to the resilient bias allows the inner diameter of the outer cylinder 6B to rotate while partially contacting the outer diameter of the inner cylinder 6A, so it is not necessary to provide a spacer 6S. (See paragraph

[0055] )

[0033] Next, regarding the roll holding portion 6 in Figure 1(a) of Example 1, in order to attach an adhesive tape roll to a conventional, one-piece, L-shaped mini tape holder that does not unfold, the roll holding portions on both sides, which are narrowed inward at the rear, are opened on both sides against the elastic force and attached, so that shallow, short cylindrical roll holding portions are provided opposite both side portions to make it easier to attach and remove.

[0034] This can be used as an inner cylinder 6A' as is, but in the case of the roll holding part 6 when holding at three points of the present invention, if the tape holder is gripped too tightly when pulling out the adhesive tape from the tape holder or when cutting the tape, the side wall part 3 will narrow, pressing on both sides of the tape roll and stopping its rotation so that it cannot be pulled out.

[0035] To solve this problem, in Example 1 of the present invention, as shown in Figure 1, holes or protrusions at both ends of the cylindrical inner tube 6A are provided at both ends of the inner tube 6A to fit into the inner tube joint portion 6A' provided opposite both side wall portions 3, thereby providing a "shortening prevention" function. In other words, this is a mechanism that prevents the distance between the two side surface portions 3 from shortening. (Also, fitting the convex portions at both ends of the inner tube 6A into the hole-shaped inner tube joints 6A' (side wall 3 at the front in the drawing) provided opposite both side wall portions 3 also serves as a "shortening stop.")

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

[0037] Next, Figure 2(a) is a diagram showing a configuration in which an outer tube 6B is placed over the 1-inch inner tube 6A with convex portions at both ends as shown in Figure 1, and a small-diameter tape roll B is attached to the roll holding part 6 having a hole-shaped inner tube joint part 6A'. (The center of FIG. 2 shows different types of outer cylinders 6B, which will be described later in paragraph

[0054] and after.) In this case, the rotary roller is a separate, single piece, tape guide portion 5 fitted into opposing notches in the upper part of both side wall portions 3.

[0038] Figure 2(b) is a schematic cross-sectional view of the small diameter tape roll B, which is attached to the roll holding section 6, which has a double cylindrical structure with the outer tube 6B covering the inner tube 6A, and is therefore being pressed more strongly by the resilient roll spring plate 4, which has increased restoring force.

[0039] Next, FIG. 3(a) is a diagram showing a large diameter tape roll E attached to the mini tape holder of the present invention. The tape guide portions 5 on both sides of the inner surface of the side wall portion 3 receive the large diameter tape roll E when it is pushed by the repulsive force of the roll resilience plate 4, and act as a "stopper."

[0040] Another feature of the present invention is that the tape roll E, which has a standardized inner diameter equal to or greater than the outer diameter of the roll holding portion 6 of the inner tube 6A or outer tube 6B, which is provided integrally or separately, is held at three points. Next, FIG. 3(b) is a schematic cross-sectional view showing that the large diameter tape roll E is held at three points. That is, the first point is the roll spring plate 4 indicated by I in the figure, the second point is the roll holding portion 6 indicated by II in the figure, and the third point is the tape guide portion 5 indicated by III in the figure, which is a schematic cross-sectional view showing holding at three points.

[0041] In this way, the present invention reduces friction at all three contact points, which are the major factors in holding the three points together, by using the rotating rollers at II and III to reduce "rolling friction" and the smooth surface 4S at I to reduce "sliding friction." At the same time, the roll spring plate 4 is constantly configured with a "pressing function." Not only can all standardized tape rolls be used with one unit, but the tape holder has also been made compact. [Example]

[0042] Next, FIG. 4(a) is a diagram showing the configuration of Example 2 in which one side wall portion 3 is an expandable tape holder. Alternatively, it may be a type that does not have a hinge that opens on one side, but has a separate lid (cap) that is placed over it.

[0043] Furthermore, the tape guide portion 5 here is a single rotating roller on one side of the side wall portion 3, which assembles the deployment plate and is fitted on the other side. Unlike the first embodiment, the roll holding portion 6 of the inner cylinder 6A does not shrink in its structure, and therefore does not require a shrinkage stopper. Furthermore, if grooves are cut into the outer surface of the rotating roller of the tape guide portion 5, the grooves function effectively as a stopper with less friction and also as a tape deterrent, as the contact area is smaller and the tape is less likely to stick.

[0044] Furthermore, in Figure 4(a), the inner tube 6A of the roll holding part 6 is configured to be longer than one side of the side wall part 3 and have a protruding concave tube at the end, and on the other side is a shorter convex tube that fits together using a spigot-type fitting. In addition, in Example 1, to mount the tape roll, the side wall portions 3 on both sides are opened while the roll holding portion 6 of the inner cylinder 6A and the outer cylinder 6B is inserted into the inner diameter of the tape roll. Here, a tape roll is inserted into one of the long concave cylinders, and then the short convex cylinder is joined using a countersunk mechanism.

[0045] Furthermore, Figure 4(b) is a diagram showing the state just before assembly (connection) of a single rotating roller type tape guide unit 5 and the inner tube (6A) of the 1-inch tape roll in Figure 4(a) with the outer tube 6B covering it.

[0046] Also, here, as in Example 1, if an outer cylinder 6B is placed over the inner cylinder 6A for 1 inch in Figure 4(a), it becomes a double cylinder as shown in Figure 4(b), and can accommodate all tape rolls with inner diameters from 1 inch to 3 inches. Also, the 1.5 inch inner cylinder 6A in FIG. 4(a) is heavier when pulling out the tape than the rotating double cylinder, and can accommodate all tape rolls except for tape rolls with an inner diameter of 1 inch. [Example]

[0047] Next, FIG. 5(a) is a diagram showing the configuration of a tape holder in Example 3, in which the side wall portions 3 on both sides are unfolded and assembled, using unfolding plates.

[0048] FIG. 5(a) shows an adhesive tape cleaner having the structure of claim 4. As shown in the figure, this is also a diagram of the shape of an unfolding plate that is integrally extended with a hinge-type tape tip fixing part 7 that attaches and fixes the tip of the adhesive tape on the outer surface of the rear end of the roll spring plate 4, for use as an adhesive tape cleaner.

[0049] FIG. 5(b) shows the deployment plate of FIG. 5(a) covered with an outer cylinder 6B and assembled. Furthermore, if one tape guide portion 5 is divided as shown in the figure, friction is further reduced and rotation acts lightly. Furthermore, the roll spring plate 4 in the above-mentioned <Example 1> and <Example 2> may be a separate body provided with a hinge-like PP resin sheet or a tape tip fixing part (7) such as a clip to deal with [Claim 5].

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

[0051] In FIG. 5(a), a 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 FIGS. 6(a) and 6(b).

[0052] The following FIG. 6 shows the above-mentioned <Example 3> in which all of claims 1 to 6 of the present invention are provided on the tape holder of the deployment plate. First, FIG. 6(a) shows the configuration of claim 6, which can accommodate different widths of tape rolls. In FIG. 6(a), folding claw guide portions (8) are provided opposite to each other on the inner surface of the roll spring plate 4, and they sandwich and guide the tape roll by the spring force that the claws have when they are standing. That is, here, the folding claw guide portions 8 are provided opposite each other and can rotate outward from the inner surface of the roll spring plate 4 so that narrow adhesive tape rolls of different widths can be clamped.

[0053] The cross-sectional view of Figure 6(b) shows a typical folded claw-shaped guide portion being pushed outward and sandwiched between both sides of a narrow adhesive tape roll by a resilient force, and this mechanism prevents lateral slippage by sandwiching the narrow adhesive tape roll from all directions with the repulsive force combined with the roll spring plate 4. (FIG. 5(a) shows a case where the side wall 3 is provided on one side when there is no margin in the width and it is impossible to provide them facing each other.) Furthermore, the tape tip fixing portion 7 may be provided on the outer surface of the roll spring plate 4 and the folding claw guide portion 8 may be provided on the inner surface in the form of a single sheet, which may be folded in half and attached to the front and back.

[0054] FIG. 6(b) shows an inner cylinder 6A of the minimum diameter roll holding portion covered with an outer cylinder 6B provided with a spacer, and a small diameter tape roll B attached thereto. Furthermore, this is a schematic cross-sectional view of the folding claw guide portion 8 of [Claim 6] standing up.

[0055] Next, regarding the outer cylinder 6B of the double cylinder according to claim 2 of the present invention, The different types of outer cylinders 6B shown in the center of FIG. 2 and described in paragraph

[0036] will now be described. First, in FIG. 6(b), there is a thick-walled outer cylinder 6B on the upper right, and further on the left side of the outer cylinder 6B in the center of FIG. Next, the adjacent outer tube 6B has a spacer 6S to ensure a gap on the inner diameter. (See the bottom center of Figure 6, and also the center of the outer tube 6B in the center of Figure 2.) Furthermore, there is also a type in which a gear-shaped spacer 6S is provided on the outer periphery of the outer cylinder 6B. (In Figure 6(b), it is in the upper center, and furthermore, it is on the right side of the outer tube 6B in the center of Figure 2.) That is, when the roll holding unit 6 has a double concentric cylindrical configuration, In addition to the thick-walled outer cylinder 6B, the outer cylinder 6B needs to be thick in order to cover the inner cylinder 6A with the outer cylinder 6B and make contact with the inner cylinder 6A. If a cylinder of normal thickness (approximately 2 mm) were to be inscribed, a considerable amount of space would be created. To solve this problem, spacer 6S was installed to ensure space. [Example]

[0056] The double cylinder in which the spacer 6S is not provided on the inner diameter of the outer cylinder 6B of normal thickness is <Example 4>. In other words, as shown in the upper center of Figure 6 and the upper left of Figure 6(b), it is a double eccentric cylindrical shape in which no spacer 6S is provided on the inner diameter of the outer cylinder 6B, and as mentioned many times above, due to the "pressing function" caused by the strong repulsive force of the roll spring plate 4, the outer diameter of the inner cylinder 6A rotates while partially contacting the inner diameter of the outer cylinder 6B, so it is not necessary to provide a spacer 6S. Furthermore, the eccentricity increases the space available, allowing a thicker tape roll to be held. [Example]

[0057] Next, FIG. 7(a) shows a type of outer cylinder 6B, in which the outer peripheral surface is a gear-shaped outer cylinder 6B', which is <Example 5>. In the present invention, the spacer 6S of the roll holding portion 6 is provided on the inner diameter of the outer cylinder 6B, but in <Example 5> of [Claim 4], as shown in Figure 7, it is provided on the outer diameter, which is the outer peripheral surface. In other words, the outer cylinder 6B, which is inscribed and rotatably overlapped with the inner cylinder 6A, has an outer diameter of just under 1.5 inches, and a gear-shaped spacer 6S is attached to the outer diameter of the outer cylinder 6B.Compared to a case where the spacer 6S is attached to the inner diameter, the inscribed area is larger, and the deep grooves have a good effect, resulting in functional beauty. FIG. 7(b) is a schematic cross-sectional view of the gear-shaped outer cylinder 6B' with the small diameter tape roll B set in a holder.

[0058] Also, the thick-walled outer cylinder 6B may be provided with a gear-shaped outer cylinder having deep grooves, or may be covered with a gear-shaped rubber tube.

[0059] When using the double cylinder of the present invention with a minimum diameter tape roll A having an inner diameter of 1 inch, the outer cylinder 6B covering the tape roll A is removed and the tape roll A is set in the inner cylinder 6A.

[0060] In addition, in paragraphs

[0028] to

[0031] , we have explained the advantage of the "pressing function" due to the spring bias, but it can also be used as a mini holder for double-sided tape rolls, types of paper tape without adhesive surfaces, PP and PE film rolls for packaging, and even stickers and label tape.

[0061] Furthermore, the present invention is free to combine various aspects and is not limited to the examples.

[0062] Next, how to use the present invention as an adhesive tape cutter will be described with reference to FIG. 8(a). Once you have pulled out the adhesive tape to the desired length, cut it using the tape cutting section 2. Also, when directly attaching the tape during packing work on cardboard boxes, first pull out the adhesive tape, and while attaching it, stop it at the point where you want to cut it, and then place the adhesive tape against the tape cutting part 2 and cut it, as shown in Figure 8(b).

[0063] Next, in FIG. 9(a), a method for setting up and using an adhesive tape cleaner in which a tape tip fixing part 7 of the type shown in FIG. 5(a) is provided at the rear end of a roll spring plate 4 will be explained. (Note that the tape tip fixing part 7 in FIG. 6(a) is a type further equipped with a locking mechanism, but is not limited to this as long as it can fix the tape tip.)

[0064] First, the adhesive tape is pulled out in the same way as with the adhesive tape cutter described above, and then, instead of cutting it with the tape cutting unit 2, the adhesive tape is simply turned over with the tape cutting unit 2 as shown in Figure 9(a) and pulled out along the roll spring plate 4. Furthermore, as shown in FIG. 9(b), the adhesive tape tip is sandwiched between the hinges of the tape tip fixing portion 7 provided at the rear end portion, and is stuck and fixed. If the adhesive tape is loose, reverse the tape roll to remove the slack.

[0065] Furthermore, as shown in FIG. 9(b), the adhesive side of the roll spring plate 4 is turned downwards and pressed onto the dust particles or loose hair to adhere it. Once you have finished collecting, pull the knob at the tip and the adhesive surface will come off, then fold it in half to seal in any debris or hair, then cut it off using the tape cutting section 2 and discard it.
