Description

The present invention relates to an ornament fixing tape, and more particularly to an ornament fixing tape for fixing an ornament to a user's earlobe.

Conventionally, in order to fix a reusable ornament such as a pseudo jewel to an earlobe like a pierced earring, an ornament fixing tape having adopted a double-sided tape structure having adhesive surfaces on both sides as a whole has been known. ..

Further, as such an ornament fixing tape, it is known that shape retention is ensured by using two adhesive tapes sandwiching a synthetic resin plate (see, for example, Patent Document 1).

Then, after each adhesive tape is attached to both sides of the synthetic resin plate, it is punched into a predetermined shape (for example, a perfect circle shape or a star shape) by a punching process. At this time, both of the adhesive tapes are punched in the same shape and the same size.

In the accessory fixing tape punched to the same shape and size in this way, the ornament is attached to the other surface of one adhesive tape, and the adhesive surface of the other adhesive tape is attached to the earlobe. ..

Here, in the case where accessories such as pseudo jewels are simply attached directly to the other surface of one adhesive tape, for example, accessories such as pseudo jewels are made of a thin metal plate having a diameter of about 2 mm to 10 mm. After being attached to the front surface, the back surface of the metal plate may be attached to the other surface of one adhesive tape, and a swing accessory may be attached to the metal plate via a chain or the like (for example, Patent Document). 2). In the following description, the case where all of these accessories, metal plates, and swinging accessories are shown is collectively referred to as "decorative item".

Next, an embodiment according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, the ornament J is fixed to the earlobe of the user P via the ornament fixing tape 1.

As shown in FIG. 2A, in the present embodiment, the ornament J is made of metal after, for example, an accessory 11 such as a pseudo jewel is attached to the surface of a thin metal plate 12 having a diameter of about 3 mm to 6 mm. A swing accessory 14 is attached to the plate 12 via a chain 13. In the following description, the case where the accessories 11, the metal plate 12, the chain 13, and the swinging accessory 14 are shown as a whole is collectively referred to as “decoration J”. It should be noted that the ornament J itself is simply provided when the accessory 11 such as a pseudo jewel is provided on the metal plate 12 and the chain 13 and the swinging accessory 14 are not provided, or when a plurality of large and small accessories 11 are provided on the metal plate 12. Is not limited.

As shown in FIG. 2B, the decorative fixing tape 1 is formed by laminating the first tape 20 and the second tape 30 having different characteristics on one side thereof, and when not in use, other than the first tape 20. Release papers 2 and 3 are provided on the surface and the other surface of the second tape 30.

As shown in FIG. 2C, the release paper 2 that protects the other surface of the first tape 20 is peeled off when the metal plate 12 of the ornament J is attached, and as shown in FIG. 2D, the release paper 2 is peeled off. The metal plate 12 is attached to the other surface of the first tape 20 so as to coincide with each other. Then, if the release paper 3 of the second tape 30 is peeled off, the ornament J can be fixed to the earlobe by attaching the other surface of the second tape 30 to the earlobe.

As shown in FIG. 3A, a double-sided adhesive tape having adhesive layers 22 and 23 on both sides of the tape base material layer 21 is used for the first tape 20. Specifically, a double-sided adhesive tape manufactured by 3M Japan Ltd. is used.

The double-sided adhesive tape as the first tape 20 is a double-sided adhesive tape in which a non-woven base material is used for the tape base material layer 21, and a low VOC acrylic pressure-sensitive adhesive is used on both sides, and the total tape thickness is 150 μm. A release paper having a thickness of 110 μm, an adhesive strength of 8.2 N / cm (against a stainless steel plate), and a tape color colorless and translucent can be used.

As a result, the surface 22a of one of the adhesive layers 22 of the tape base material layer 21 is an adhesive surface located on one surface of the first tape 20. Similarly, the surface 23a of the other adhesive layer 23 of the tape base material layer 21 is an adhesive surface located on the other surface of the first tape 20.

By using a high-strength special non-woven fabric base material, the first tape 20 is hard to be torn when peeled from the first tape 20 in order to reuse the ornament J, and the ornament J is cleanly peeled from the first tape 20. The ornament J can be reused without the metal plate 12 being deformed. Further, if a PET separator such as a silicone-treated flat paper is applied to the release paper 2 and temporarily attached to the adhesive layer 23, the release paper 2 can be easily peeled off, and the release strength of the release paper 3 of the second tape 30 can be easily peeled off. By setting the peeling strength (adhesive strength) to be lower than (adhesive strength), the release paper 2 can be peeled off first in order to bond the decorative item J.

As shown in FIG. 3A, the medical single-sided adhesive tape provided with the adhesive layer 32 on one side of the tape base material layer 31 which is the second tape 30 conforms to ISO10993 for biocompatibility evaluation of medical devices. Is used. Specifically, an adhesive tape for skin application manufactured by 3M Japan Ltd. is used.

This adhesive tape for skin application is a highly waterproof single-sided adhesive tape based on a polyethylene film, and uses an acrylic adhesive for skin application, with an adhesive layer thickness of 40 μm, a tape base material thickness of 90 μm, and a total tape thickness of 130 μm. A release paper having a thickness of 120 μm, an adhesive strength of 4.0 N / cm, and a tape base color of colorless can be used.

As a result, the surface 31a of the tape base material layer 31 is a non-adhesive surface located on one surface of the second tape 30. Similarly, the surface 31a of the other adhesive layer 32 of the tape base material layer 31 is an adhesive surface located on the other surface of the second tape 30.

Then, as shown in FIG. 3B, one surface (22a) of the first tape 20 and one surface (31a) of the second tape 30 are bonded to each other, and the other surfaces (23a, 32a) are respectively bonded to the adhesive surface. The outer shape of the first tape 20 and the outer shape of the second tape 30 are the same shape (for example, substantially a perfect circle), and the size of the first tape 20 is larger than the size of the first tape 20. The size of the two tapes 30 is formed to be large, and the outer peripheral edge portion 33 of the second tape 30 protrudes from the outer peripheral edge 24 of the first tape 20 by a uniform predetermined width W. In the following description, the state in which the outer peripheral edge portion 33 of the second tape 30 protrudes from the outer peripheral edge 24 of the first tape 20 is also referred to as an “offset structure”.

On the other hand, as shown in FIG. 4A, a plurality of decorative fixing tapes 1 including the first tape 20 and the second tape 30 are provided, for example, in the vertical and horizontal directions with respect to the rectangular release paper 3.

Then, as shown in FIG. 4B, the release paper 3 is formed with a perforation C so as to be separable in the row or column direction, and the center of the second tape 30 is formed inside the perforation paper 3. A slit S extending in the vicinity is formed. The slit S is for facilitating the peeling of one decorative fixing tape 1 from the release paper 3.

Therefore, as shown in FIG. 4C, after the release paper 2 is peeled off from the first tape 20, the ornament J is fingered together with the accessory 11 so that the metal plate 12 coincides with the first tape 20. By pressing the release paper 3 with the like (see the thick arrow) and then spreading the release paper 3 so as to tear the slit S, the one piece of the accessory fixing tape 1 to which the ornament J is attached is the release paper 3. Can be peeled off from.

At this time, since the release paper 2 and the release paper 3 need to be peeled off from the first tape 20 first as described above, the adhesive force of the release paper 2 to the first tape 20 is the second. It is preferably weaker than the adhesive force of the release paper 3 to the tape 30.

Next, the conventional accessory fixing tape is used as the adherend of the comparative example, the ornament fixing tape 1 shown in the above embodiment is used as the adherend of the example, and the ornament J is adhered to the vibration test apparatus. An acceleration test was conducted by attaching and fixing the accessory J through a rest <* 1>, and a measurement experiment was conducted on the time until the accessory J attached and fixed to each adherend fell off.

In this measurement test, each measurement with the set parameters (* 2> is completed in 600 seconds, and the limit test is to keep swinging the parameters in the high load direction until the ornaments fall off.

When the result that the performance difference of each adherend can be clearly judged, that is, the state where one of them remains to the end is obtained, that parameter is set as the limit point, and the same parameter is used for four test data. I got it.

Further, in the above * 1, a release liner having a silicone treatment on the surface was used for the adherend in order to reproduce the condition that the tape is more easily peeled off. Further, in the above * 2, the frequency <Hz> and the acceleration <G> are set as parameters, and if no result is obtained, the weight shown in the list of various conditions in FIG. 5 is added.

As a result of conducting this test, as shown in FIG. 6, it was found that there was a clear difference in the sticking holding time between the example and the comparative example. In addition, in this test, even if a weight is added as a pseudo ornament J and the weight is 10.8 g over the normal ornament J weight of 0.8 g, the average value of the number of steps changes annually (gender). (By age group) It was found that it can withstand 5500 vibrations set with reference to the average value of 6231 steps for all women in the 2016 results. From the viewpoint of the safety factor, it was found that this result has a clear advantage between the examples and the comparative examples. As a result of the evaluation, as a result of calculating the P value (P-Value) regarding the statistical reliability based on the result shown in FIG. 6, the comparison reference value is 0.05, and the example is 0.014. It was far below the limit, and we were able to obtain results that could be judged as "statistically significant differences" in the test data.

As described above, the decorative fixing tape 1 is a decorative fixing tape 1 for attaching the decorative J to the user's earlobe, and is attached to the first tape 20 to which the decorative J is attached and the earlobe. The first tape 20 is provided with a second tape 30, and one surface of the first tape 20 and one surface of the second tape 30 are bonded to each other to form a double-sided tape structure in which each other surface is an adhesive surface. The outer shape and the outer shape of the second tape 30 are made the same shape, and the size of the second tape 30 is formed larger than the size of the first tape 20, so that the outer circumference 24 to the second tape of the first tape 20 is formed. An offset structure is adopted in which the outer peripheral edge portion 33 of 30 is projected.

That is, in the decorative fixing tape 1, the decorative J is bonded to the adhesive surface of the other surface of the first tape 20 by bonding one side of the first tape 20 and one side of the second tape 30 of two different types. By attaching the adhesive surface of the other surface of the second tape 30 to the earlobe in this state, the ornament J can be fixed to the earlobe. Further, the outer shape of the first tape 20 and the outer shape of the second tape 30 are the same shape. At this time, although the outer shape itself is the same, the size of the first tape 20 and the size of the second tape 30 are formed to be larger than the size of the first tape 20. As a result, the outer peripheral edge portion 33 of the second tape 30 protrudes from the outer peripheral edge 24 of the first tape 20.

Therefore, the outer shape of the first tape 20 and the outer shape of the second tape 30 are made the same shape, and the size of the second tape 30 is formed larger than the size of the first tape 20, so that the first tape 20 is formed. Since the outer peripheral edge 33 of the second tape 30 protrudes from the outer peripheral edge 24 of the tape, the soft earlobe sways and the swaying accessory 14 applied to the hard metal plate 12 that occurs when the user walks or the like. It is possible to absorb the moment of force against the pressure on the adhesive surface of the second tape 30 having a large area and prevent the ornament J from falling off from the ornament fixing tape 1.

Further, the second tape 30 is formed larger than the first tape 20 in the radial direction in the range of 1 mm to 5 mm, and is bonded to each other so that the entire outer peripheral edge portion 33 protrudes.

Therefore, the outer peripheral edge 33 of the second tape 30 protrudes from the outer peripheral 24 of the first tape 20 so that the entire surface protrudes in the radial direction in the range of 1 mm to 5 mm.

In this way, the entire outer peripheral edge 24 of the first tape 20 protrudes in the radial direction in the range of 1 mm to 5 mm, and in particular, the outer peripheral edge 33 of the second tape 30 protrudes uniformly so as to protrude entirely. As a result, the absorption of the moment of force on the adhesive surface on the earlobe side with respect to the accessory J can be made uniform, and the accessory J can be efficiently prevented from falling off from the accessory fixing tape 1.

Further, the first tape 20 uses a double-sided adhesive tape having adhesive layers 22 and 23 on both sides of the tape base material layer 21, and the second tape 30 uses an adhesive layer on one side of the tape base material layer 31. A single-sided adhesive tape for medical use including 32 is used, and the non-adhesive surface of the tape base material layer 21 of the second tape 30 is bonded to the adhesive layer 22 on one side of the first tape 20 to other than the first tape 20. The adhesive layer 23 on the surface and the adhesive layer 32 on the other surface of the second tape 30 are the adhesive surfaces, respectively.

Therefore, when the first tape 20 and the second tape 30 are bonded together, the adhesive surface provided on one surface of the first tape 20, which is a double-sided adhesive tape having adhesive layers 22 and 23 on both sides of the tape base material layer 21. The non-adhesive surface of one side of the second tape 30, which is a medical single-sided adhesive tape having an adhesive layer 32 on one side of the tape base material layer 31, is attached to the adhesive layer 22 made of (22a). That is, the outer peripheral edge portion 33 on one surface of the second tape 30 protruding from the outer peripheral 24 of the first tape 20 is a non-adhesive surface.

Therefore, by making the outer peripheral edge portion 33 of one surface of the second tape 30 protruding from the outer peripheral edge 24 of the first tape 20 a non-adhesive surface, the outer peripheral edge portion 33 of the second tape 30 is attached to the first tape 20. It is possible to prevent the user's hair from sticking to the outer peripheral edge portion 33 of the second tape 30.

The first tape 20 is made of a sheet material containing at least one of a non-woven fabric, a vinyl-based resin, a polysterene-based resin, an olefin-based resin, a polyester-based resin, a nylon-based resin, a polyurecun-based resin, and an acrylic-based resin as main components. A pressure-sensitive adhesive layer 22 made of an acrylic, urethane-based, silicon-based, or synthetic rubber-based adhesive on both one side and the other side of the tape base material layer 21. A double-sided adhesive tape comprising 23 is used, and the second tape 30 is a non-woven fabric, a vinyl-based resin, a polystyrene-based resin, an olefin-based resin, a polyester-based resin, a nylon-based resin, a polyurethane-based resin, an acrylic-based resin, and the like. A tape base layer 31 made of a sheet material containing at least one of the above and the other surface of the tape base layer 31 are made of any of acrylic, urethane, silicon, and rubber. A single-sided adhesive tape for medical use conforming to ISO10993 for evaluating the biocompatibility of a medical device including an adhesive layer 32 made of an adhesive is used, and a second tape 30 is attached to an adhesive layer 22 on one side of the first tape 20. The adhesive layer 23 on the other surface of the first tape 20 and the adhesive layer 32 on the other surface of the second tape 30 are bonded to each other as adhesive surfaces.

Therefore, when the first tape 20 and the second tape 30 are bonded together, the adhesive surface provided on one surface of the first tape 20, which is a double-sided adhesive tape having adhesive layers 22 and 23 on both sides of the tape base material layer 21. A non-adhesive surface of one side of the second tape 30, which is a medical single-sided adhesive tape having an adhesive layer 32 on one side of the tape base material layer 31, is attached to the adhesive layer 22 made of the adhesive layer 22. That is, the outer peripheral edge portion 33 on one surface of the second tape 30 protruding from the outer peripheral 24 of the first tape 20 is a non-adhesive surface. Therefore, as the tape base material layers 21, 31 and the adhesive layers 22, 23, 31 of the first tape 20 and the second tape 30, materials suitable for the intended use are selected.

In this way, versatility can be improved by selecting materials suitable for the intended use as the tape base material layers 21, 31 and the adhesive layers 22, 23, 32 of the first tape 20 and the second tape 30. can.

Further, the adhesive strength of the adhesive layer 23 of the first tape 20 is higher than the adhesive strength of the adhesive layer 32 of the second tape 30.

Therefore, the adhesive strength of the adhesive layer 23 of the first tape 20 to which the ornament J is attached is higher than the adhesive strength of the adhesive layer 32 of the second tape 30 to be attached to the earlobe.

As described above, the adhesive strength of the adhesive layer 23 of the first tape 20 to which the ornament J is attached is higher than the adhesive strength of the adhesive layer 32 of the second tape 30 to be attached to the earlobe. It is possible to prevent the ornament J from falling off from the first tape 20 when the second tape 30 is peeled off from the earlobe.

The adhesive strength of the adhesive layer of the first tape 20 is 8.2 N / cm or more, and the adhesive strength of the adhesive layer of the second tape 30 is in the range of 4.0 to 4.5 N / cm. be.

Therefore, the adhesive strength of the adhesive layer 23 of the first tape 20 to which the ornament J is attached is more than double the adhesive strength of the adhesive layer 32 of the second tape 30 attached to the earlobe. There is.

In this way, the adhesive strength of the adhesive layer 23 of the first tape 20 to which the ornament J is attached is more than double the adhesive strength of the adhesive layer 32 of the second tape 30 attached to the earlobe. By doing so, it is possible to easily secure the effect of suppressing the decoration J from falling off from the first tape 20 when the second tape 30 is peeled off from the earlobe.

The decorative fixing tape 1 according to the present embodiment adopts an offset structure between the first tape 20 and the second tape 30, and in particular, by setting the difference in diameter to 1 mm or less, the decorative J is an earlobe. When fixed to the earlobe, the hard metal plate 12 is attached to the earlobe without the outer peripheral edge 33 of the second tape 30 protruding from the outer periphery 24 of the first tape 20 being conspicuous in combination with the fact that the tape color is transparent. Even in the fixed state, it is possible to prevent the metal plate 12 from easily falling off from the second tape 30.

[Acrylic adhesive]
Acrylic adhesives are adhesives made of acrylic polymers. The adhesive physical characteristics can be controlled by setting conditions such as selection of the type of monomer, molecular weight of the polymer, and cross-linking density. In addition, it has excellent transparency, heat resistance, and weather resistance, has a wide range of adhesive strength, and has a high degree of freedom from weak adhesive type to strong adhesive type. Therefore, it is possible to ensure high convenience as the decorative fixing tape 1 that requires removability.

[Urethane adhesive]
The urethane-based pressure-sensitive adhesive is a pressure-sensitive adhesive made of polyurethane obtained by condensing compounds having an isocyanate group and a hydroxy group. It has excellent air bleeding property from the surface to be adhered at the time of sticking, and can be peeled off without adhesive residue on the surface to be adhered, so that it is highly convenient as a decorative fixing tape 1 that requires re-peelability. Can be secured.

[Silicon adhesive]
The silicon-based pressure-sensitive adhesive is a pressure-sensitive adhesive composed of a polymer having a siloxane bond as a main skeleton. It has a wide range of usable temperatures and is excellent in chemical resistance and water resistance. In particular, in the case of the slightly adhesive type, it has excellent air bleeding property with the surface to be adhered at the time of sticking, and it can be pasted without air bubbles, so that it adheres to a flexible surface to be adhered such as an earlobe. High sex can be secured.

[Rubber adhesive]
The fluidity of the pressure-sensitive adhesive derived from natural rubber has a characteristic that it is not easily lost even at a low temperature where other substances harden and become brittle. Natural rubber is made up of very long polymer chains, which become viscous when mixed with resin, making it a very flexible adhesive due to the length and fluidity of the chain molecules. Therefore, it is possible to secure high adhesiveness to a flexible surface to be adhered such as an ear canal. As the rubber-based pressure-sensitive adhesive, nitrile rubber-based rubber or synthetic rubber may be used in addition to silicon rubber or the like as long as it has elasticity and flexibility.

Therefore, the adhesive layer of these various second tapes 30 has various tape bases so as to correspond to, for example, the size and number of accessories to be applied, or the purpose of use such as the user's residential area or season. When the size and shape of the material layer are determined, an adhesive can be appropriately used according to the purpose of use.

In the above embodiment, the front view shape of the second tape 30 is shown in the same circular shape (perfect circle) as the front view shape of the first tape 20, but it is larger than the size of the first tape 20. If the size of the second tape 30 is formed to be large and the entire outer peripheral edge portion 33 of the second tape 30 protrudes from the outer periphery of the first tape 20, for example, as shown in FIG. 7, the second tape 30 It does not have to be the same shape as in the case where the front shape of the second tape 30 is a square (diamond) or, as shown in FIG. 8, the front shape of the second tape 30 is a regular octagon (regular polygon). ..

At this time, as in the square (diamond shape) shown in FIG. 7 or the regular octagon shown in FIG. 8, the vicinity of the corner portion where the outer peripheral edge portion 33 of the second tape 30 has a large amount of protrusion from the outer circumference of the first tape 20.
