Description

Technical Field

[0001] The present disclosure relates to an adherend transfer unit and an adherend transfer tool.

Background Art

[0002] Adhesive sheets for the skin are widely used for the purpose of protecting a diseased part of the skin from the outside or hiding a part of the skin from the outside. The adhesive sheet includes an adhesive tape sandwiched between a carrier sheet and a release sheet. The adhesive tape includes a base material in contact with the carrier sheet and an adhesive layer in contact with the release sheet. When the adherend is used, first, the release sheet is peeled off from the adhesive layer. Then, the laminate of the adhesive tape and the carrier sheet is attached to the skin by the adhesive layer. Subsequently, the carrier sheet is peeled off from the base material (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the length of the area that can be covered by one adhesive tape on the skin is limited to the length of the adhesive sheet. Therefore, on the skin, when the length of the area where the user wants to apply the adhesive tape is shorter than the length of the adhesive tape, a part of the adhesive tape will remain. On the other hand, when the length of the area where the user wants to apply the adhesive tape is longer than the length of the adhesive tape, or when the user wants to wrap the adhesive tape around a finger or the like, the length of the adhesive tape will be insufficient for the area to be applied.

Means for Solving the Problems

[0005] The sticker transfer unit for solving the above problems is a sticker in the form of a roll, comprising a carrier sheet, a release sheet, and a sticker tape positioned between the carrier sheet and the release sheet. The sticker tape includes a base material that contacts the carrier sheet and has a higher tensile elongation at break than the carrier sheet and the release sheet, and an adhesive layer that contacts the release sheet and is adhered to the skin after the release sheet is peeled off from the adhesive layer. The sticker transfer unit further includes the sticker with the carrier sheet positioned on the outer surface, a case that defines a space for accommodating the sticker, a supply reel around which the sticker is wound, a first take-up reel configured to wind up the portion of the release sheet peeled off from the adhesive layer, a transfer portion configured to transfer the adhesive layer to the skin while peeling the carrier sheet from the base material, and a second take-up reel configured to wind up the portion of the carrier sheet peeled off from the base material.

[0006] According to the above sticker transfer unit, by sequentially unwinding a part of the roll-shaped sticker from the supply reel, it is possible to attach a sticker tape of any length to the skin. Therefore, according to the sticker transfer tool, it is possible to increase the degree of freedom in the length of the area to which the sticker tape is applied.

[0007] In the above sticker transfer unit, it may further include a switch exposed on the outer surface of the case, a storage portion configured to store a coating agent containing at least one active ingredient for the skin, and a coating portion configured to apply the coating agent to a portion of the adhesive layer where the release sheet is peeled off and before being attached to the skin by operating the switch.

[0008] According to the above sticker transfer unit, by attaching the sticker tape to the skin using the sticker transfer tool, it is possible to position the coating agent between the adhesive layer and the skin.

[0009] In the above-described adherend transfer unit, at least one of the base material and the adhesive layer may contain at least one active ingredient for the skin.

[0010] According to the above-described adherend transfer unit, by attaching the adhesive tape to the skin, it is possible to make the active ingredient contained in at least one of the base material and the adhesive layer act on the skin.

[0011] In the above-described adherend transfer unit, between the carrier sheet and the base material, the 180° peel strength conforming to JIS Z 0237:2009 may be 550 mN / 25 mm or less, and in the adhesive layer, the 180° peel strength conforming to JIS Z 0237:2009 may be 1 N / 25 mm or more.

[0012] According to the above-described adherend transfer unit, since the carrier sheet is easily peeled from the base material and the adhesive layer is easily attached to the skin, only the adhesive tape among the adherends is easily transferred to the skin.

[0013] The above-described adherend transfer unit may further include a cutting portion that cuts the adhesive tape after the carrier sheet is peeled off by the transfer portion. According to the above-described adherend transfer unit, since the adherend transfer tool includes a cutting portion capable of cutting the adhesive tape, even if the adhesive tape contains a base material having a high tensile fracture elongation, it is easy to make the length of the adhesive tape attached to the skin an arbitrary length.

[0014] The applicator body transfer tool for solving the above problems includes a case that defines a space for accommodating a roll-shaped applicator body, a supply reel around which the applicator body is wound, a first take-up reel configured to take up a portion of the release sheet peeled from the adhesive layer, a transfer portion configured to transfer the adhesive layer to the skin while peeling the carrier sheet from the base material of the applicator body, a second take-up reel configured to take up a portion of the carrier sheet peeled from the base material, a switch exposed on the outer surface of the case, a storage portion configured to store a coating agent containing at least one active ingredient for the skin, and a coating portion configured to apply the coating agent to a portion of the adhesive layer before the release sheet is peeled off and the adhesive layer is attached to the skin when the switch is operated.

[0015] According to the above applicator body transfer tool, an applicator tape having an arbitrary length can be attached to the skin by sequentially unwinding a part of the roll-shaped applicator body from the supply reel. Therefore, according to the applicator body transfer tool, it is possible to increase the degree of freedom in the length of the area to which the applicator tape is applied. In addition, by attaching the applicator tape to the skin using the applicator body transfer tool, it is possible to position the coating agent between the adhesive layer and the skin.

Effect of the Invention

[0016] According to the applicator body transfer unit and the applicator body transfer tool of the present disclosure, the degree of freedom in the length of the area to which the applicator tape is applied can be increased.

BEST MODE FOR CARRYING OUT THE INVENTION

[0018] [First Embodiment] With reference to FIGS. 1 to 3, the first embodiment of the adherend transfer unit and the adherend transfer tool will be described.

[0019] [Adherend] FIG. 1 shows the structure of the adherend included in the adherend transfer unit. As shown in FIG. 1, the adherend 11 has a roll shape. The adherend 11 includes a carrier sheet 21, a release sheet 22, and an adhesive tape 23. The adhesive tape 23 is located between the carrier sheet 21 and the release sheet 22.

[0020] The adhesive tape 23 includes a base material 23A and an adhesive layer 23B. The base material 23A is in contact with the carrier sheet 21 and has a higher tensile break elongation than the carrier sheet 21 and the release sheet 22. The adhesive layer 23B is in contact with the release sheet 22 and is attached to the skin after the release sheet 22 is peeled off from the adhesive layer 23B. The adhesive tape 23 of the present embodiment is composed of the base material 23A and the adhesive layer 23B. The adherend 11 may include layers other than the base material 23A and the adhesive layer 23B. The adherend 11 may include, for example, a printing layer. When the adherend 11 includes a printing layer, the printing layer is located between the base material 23A and the adhesive layer 23B.

[0021] In the adherend 11, the carrier sheet 21 is located on the outer surface of the adherend 11. The carrier sheet 21, the release sheet 22, and the adhesive tape 23 each have a strip shape. The adherend 11 is wound in a roll shape such that the carrier sheet 21 is located outside with respect to the release sheet 22, whereby the carrier sheet 21 is located on the outer surface of the adherend 11.

[0022] The adherend 11 may satisfy the following Condition 1 and Condition 2. Note that the adherend 11 may satisfy only one of Condition 1 and Condition 2. That is, the adherend 11 may satisfy only Condition 1, or may satisfy only Condition 2.

[0023] (Condition 1) Between the carrier sheet 21 and the base material 23A, the 180° peel strength conforming to JIS Z 0237:2009 is 550 mN / 25 mm or less. (Condition 2) In the adhesive layer 23B, the 180° peel strength conforming to JIS Z 0237:2009 is 1 N / 25 mm or more.

[0024] When the adherend 11 satisfies Condition 1, the carrier sheet 21 is easily peeled from the base material 23A. Also, when the adherend 11 satisfies Condition 2, the adhesive layer 23B is easily attached to the skin. Therefore, when the adherend 11 satisfies both Condition 1 and Condition 2, only the adhesive tape 23 of the adherend 11 is easily transferred to the skin.

[0025] At least one of the base material 23A and the adhesive layer 23B may contain at least one active ingredient for the skin. By attaching the adhesive tape 23 to the skin, it is possible to cause the active ingredient contained in at least one of the base material 23A and the adhesive layer 23B to act on the skin.

[0026] In the adherend 11, both the base material 23A and the adhesive layer 23B may contain an active ingredient, or only the base material 23A may contain an active ingredient, or only the adhesive layer 23B may contain an active ingredient. When the base material 23A and the adhesive layer 23B contain an active ingredient, the active ingredient contained in the base material 23A and the active ingredient contained in the adhesive layer 23B may be the same as each other or different from each other.

[0027] When the base material 23A contains an active ingredient, the base material 23A and the adhesive layer 23B are configured such that the active ingredient contained in the base material 23A penetrates therethrough, whereby the active ingredient reaches the skin. When another layer is located between the base material 23A and the adhesive layer 23B, the other layer is also configured such that the active ingredient contained in the base material 23A penetrates therethrough. When the adhesive layer 23B contains an active ingredient, at least the adhesive layer 23B of the adhesive tape 23 is configured such that the active ingredient contained in the adhesive layer 23B penetrates therethrough, whereby the active ingredient reaches the skin.

[0028] The active ingredient may be, for example, a cosmetic ingredient, a beauty ingredient, and a medicinal ingredient. The active ingredient may be, for example, chitosan, glycerin, or the like.

[0029] The carrier sheet 21 is formed of a synthetic resin. The carrier sheet 21 is formed of, for example, a base material sheet and a release layer. The release layer is laminated on the base material sheet. When the carrier sheet 21 includes the base material sheet and the release layer, the release layer is in contact with the base material 23A of the adhesive tape 23. The base material sheet may be formed of, for example, a polypropylene (PP) resin, a polyethylene terephthalate (PET) resin, or the like. The base material sheet may be any one of a uniaxially stretched sheet, a biaxially stretched sheet, and an unstretched sheet. The release layer may be formed of, for example, a silicone resin.

[0030] The carrier sheet 21 may be composed only of the above-described base material sheet. In this case, among the base material sheets, a process for facilitating the peeling of the base material 23A from the base material sheet may be applied to the contact surface that contacts the base material 23A. The process for the contact surface of the base material sheet may be, for example, embossing. The thickness of the carrier sheet 21 may be, for example, 10 μm or more and 400 μm or less.

[0031] The release sheet 22 is configured such that the release strength between the release sheet 22 and the adhesive layer 23B is smaller than the release strength between the carrier sheet 21 and the base material 23A. The release sheet 22 is formed from a synthetic resin. The release sheet 22 is formed, for example, from a base material sheet and a release layer. The release layer is laminated on the base material sheet. When the release sheet 22 includes a base material sheet and a release layer, the release layer is in contact with the adhesive layer 23B of the sticking tape 23. The base material sheet may be formed from, for example, polyethylene terephthalate (PET) resin or the like. The base material sheet may be any one of a uniaxially stretched sheet, a biaxially stretched sheet, and a non-stretched sheet. The release layer may be formed from, for example, a silicone resin.

[0032] The release sheet 22 may be composed only of the above-described base material sheet. In this case, among the base material sheets, a process for facilitating the peeling of the adhesive layer 23B from the base material sheet may be applied to the contact surface that contacts the adhesive layer 23B. The process for the contact surface of the base material sheet may be, for example, embossing. The thickness of the release sheet 22 may be, for example, 12 μm or more and 350 μm or less.

[0033] The base material 23A is formed of a synthetic resin. The synthetic resin for forming the base material 23A may be, for example, a polyurethane resin. Thereby, it is possible to obtain the base material 23A with high sticking suitability. The thickness of the base material 23A may be, for example, 5 μm or more and 30 μm or less. The thin base material 23A made of a polyurethane resin can be easily extended even when the external force applied to the base material 23A for extending the base material 23A is small. Therefore, the base material 23A can have high followability with respect to the shape of the object to which the sticking tape 23 is stuck and high adhesiveness with respect to the object to be stuck.

[0034] On the other hand, the base material 23A having high followability with respect to the shape of the object to be stuck also has high followability with respect to the carrier sheet 21 covering the base material 23A. Therefore, when a force for peeling the carrier sheet 21 from the base material 23A acts on the carrier sheet 21, the base material 23A is likely to deform following the deformation of the carrier sheet 21.

[0035] The tensile breaking elongation of the base material 23A may be, for example, 130% or more. The tensile breaking elongation can be determined in accordance with JIS K 7161-1:2014 (ISO 527-1) "Plastics - Methods for determining tensile properties - Part 1: General principles" and JIS K 7127:1999 (ISO 527-3) "Plastics - Test methods for tensile properties - Part 3: Test conditions for films and sheets". When the measurement object does not have a yield point, the tensile fracture strain is measured, and when it has a yield point, the nominal strain at tensile fracture is measured, and the tensile breaking elongation can be determined using these measured values.

[0036] The 100% elongation tensile strength of the base material 23A may be, for example, 4 N / cm or less. The 100% elongation tensile strength is a value obtained by dividing the magnitude of the force measured when the strain defined in JIS K 7161-1:2014 (ISO 527-1) "Plastics - Methods for determining tensile properties - Part 1: General principles" reaches a specified value (100%) by the width of the test piece. The 100% elongation tensile strength (T) (N / cm) can be determined by the following formula.

[0037] T = F / W In the above formula, F is the magnitude of the measured force (N), and W is the width (cm) of the test piece.

[0038] Note that the base material 23A may be formed from a synthetic resin other than the polyurethane resin. Examples of the synthetic resin other than the polyurethane resin may include polyvinylidene fluoride resin, ethylene-vinyl acetate copolymer resin, polypropylene resin, and polyethylene terephthalate resin.

[0039] The adhesive layer 23B is formed from a synthetic resin, similar to the base material 23A. The synthetic resin for forming the adhesive layer 23B may be, for example, a polyurethane resin. The thickness of the adhesive layer 23B may be, for example, 5 μm or more and 25 μm or less.

[0040] [Attachment Transfer Unit] Figure 2 shows the structure of the attachment transfer unit. Note that in Figure 2, for convenience of explanation, a part of the case included in the attachment transfer tool is broken.

[0041] As shown in Figure 2, the attachment transfer unit 10 includes an attachment transfer tool 12 and an attachment 11. The attachment transfer tool 12 includes a case 31, a supply reel 32, a take-up reel 33, and a transfer part 34. The case 31, the supply reel 32, the take-up reel 33, and the transfer part 34 are formed from, for example, a synthetic resin.

[0042] Case 31 defines a space 31S for accommodating the adherend 11. The supply reel 32 has a roll-shaped adherend 11 wound thereon. The take-up reel 33 is configured to take up the portion of the release sheet 22 peeled off from the adhesive layer 23B. The transfer unit 34 is configured to transfer the adhesive layer 23B onto the skin while peeling the carrier sheet 21 from the base material 23A. In the example shown in FIG. 2, the above-described take-up reel 33 is configured to further take up the portion of the carrier sheet 21 peeled off from the base material 23A. That is, in the example shown in FIG. 2, one take-up reel 33 provided in the adherend transfer tool 12 functions as a first take-up reel for taking up a part of the release sheet 22 and a second take-up reel for taking up a part of the carrier sheet 21.

[0043] By sequentially unwinding a part of the roll-shaped adherend 11 from the supply reel 32, it is possible to attach an adhesive tape 23 having an arbitrary length to the skin. Therefore, according to the adherend transfer unit 10, it is possible to increase the degree of freedom in the length of the area to which the adhesive tape 23 is applied.

[0044] The plane orthogonal to the rotation axis of the supply reel 32 can be defined by the X direction and the Y direction which is orthogonal to the X direction. The normal direction of the XY plane defined by the X direction and the Y direction, that is, the depth direction of the paper surface is the Z direction. The rotation axes of the respective reels 32, 33 extend along the Z direction.

[0045] The adherend transfer tool 12 further includes a supply gear 35, a take-up gear 36, a first conveyance reel 37, and a second conveyance reel 38. The supply gear 35, the take-up gear 36, the first conveyance reel 37, and the second conveyance reel 38 are formed of, for example, synthetic resin.

[0046] Case 31 includes a main body 31A and a transfer port 31B. The main body 31A has a substantially elliptical shape when viewed from a perspective facing the XY plane. The main body 31A defines a space 31S for accommodating the adherend 11. Inside the space 31S, a supply reel 32, a take-up reel 33, a supply gear 35, a take-up gear 36, a first conveyance reel 37, and a second conveyance reel 38 are accommodated. The transfer port 31B protrudes from a part of the outer edge of the main body 31A. The transfer unit 34 is located within the transfer port 31B. The transfer unit 34 is configured to be supported by the main body 31A. The transfer port 31B has an opening that exposes the transfer unit 34 to the outside when viewed from the back to the front of the paper surface.

[0047] The supply reel 32 and the take-up reel 33 are each supported by the case 31 in a rotatable state about a rotation axis extending along the Z direction. The rotation direction of the supply reel 32 is opposite to the rotation direction of the take-up reel 33. In the example shown in FIG. 2, the supply reel 32 rotates counterclockwise, while the take-up reel 33 rotates clockwise.

[0048] The supply gear 35 is configured to rotate together with the supply reel 32. The supply gear 35 has a disk shape along the XY plane. As the supply reel 32 rotates counterclockwise, the supply gear 35 also rotates counterclockwise. The take-up gear 36 is configured to rotate together with the take-up reel 33. The take-up gear 36 has a disk shape along the XY plane. As the take-up reel 33 rotates clockwise, the take-up gear 36 also rotates clockwise. The supply gear 35 and the take-up gear 36 mesh with each other, whereby the supply gear 35 and the take-up gear 36 are configured such that the take-up gear 36 also rotates as the supply gear 35 rotates. Note that a third gear may be located between the supply gear 35 and the take-up gear 36. Thereby, the take-up gear 36 may be configured to rotate via the third gear as the supply gear 35 rotates.

[0049] In the example shown in FIG. 2, when the adherend 11 is attached to the adherend transfer tool 12, in the Z direction, the adherend 11 is positioned in front of the supply gear 35. The take-up reel 33 takes up the carrier sheet 21 and the release sheet 22 in front of the take-up gear 36 in the Z direction.

[0050] The first conveyance reel 37 and the second conveyance reel 38 are each supported by the case 31 in a rotatable state about a rotation axis extending along the Z direction. The rotation axes of the respective conveyance reels 37, 38 are parallel to the rotation axis of the supply reel 32 and the rotation axis of the take-up reel 33. The first conveyance reel 37 is positioned between the supply reel 32 and the transfer unit 34 in the conveyance path of the carrier sheet 21. The second conveyance reel 38 is positioned between the transfer unit 34 and the take-up reel 33 in the conveyance path of the carrier sheet 21.

[0051] FIG. 3 shows a cross-sectional shape of the transfer unit 34 along the ZY plane. As shown in FIG. 3, in the cross section, the transfer unit 34 has a substantially triangular shape. Among the three corner portions of the transfer unit 34, the corner portion with the largest protruding amount from the main body portion 31A of the case 31 has a curvature such that the center of curvature is located within the transfer unit 34. In the transfer unit 34, substantially triangular cross sections are continuous along the X direction.

[0052] The adherend transfer tool 12 may further include a cutting portion 39. The cutting portion 39 is configured to be able to cut the adhesive tape 23 from which the carrier sheet 21 has been peeled off by the transfer unit 34. The cutting portion 39 is formed of, for example, a synthetic resin. In FIG. 2, the illustration of the cutting portion 39 is omitted. Since the adherend transfer tool 12 includes the cutting portion 39 capable of cutting the adhesive tape 23, even if the adhesive tape 23 includes a base material 23A having a high tensile breaking elongation, it is easy to make the length of the adhesive tape 23 attached to the skin an arbitrary length.

[0053] In the example shown in FIG. 3, the cutting portion 39 is configured to be able to sandwich a laminate of the carrier sheet 21 and the adhesive tape 23 between the transfer portion 34 and the cutting portion 39. The cutting portion 39 has flexibility that allows it to bend in both the direction approaching the transfer portion 34 and the direction moving away from the transfer portion 34.

[0054] When viewed from a perspective facing the XY plane, the cutting portion 39 has, for example, a U shape. The cutting portion 39 is attached to the case 31 so as to surround the transfer portion 34 when viewed from a perspective facing the XY plane. The cutting portion 39 includes a cutting blade 39A and a pair of arm portions 39B. The cutting blade 39A extends along the X direction. Each arm portion 39B extends along the Y direction.

[0055] When the adhesive tape 23 is transferred to the skin by the transfer portion 34, first, the cutting blade 39A of the cutting portion 39 is pressed against the skin, and thereby each arm portion 39B bends with the corner of the cutting blade 39A as a fulcrum. As a result, since the cutting portion 39 deforms in the direction moving away from the transfer portion 34, the adhesive tape 23 is not cut by the cutting edge of the cutting blade 39A, and the transfer portion 34 presses the adhesive tape 23 against the skin.

[0056] When the force pressing the cutting blade 39A against the skin is released, the deformation of the cutting portion 39 is released, and thereby the cutting portion 39 approaches the transfer portion 34. Further, an external force acts such that the cutting edge of the cutting blade 39A approaches the transfer portion 34 with the corner of the cutting blade 39A as a fulcrum, and the cutting blade 39A cuts the adhesive tape 23.

[0057] Note that the cutting portion 39 may have an L shape when viewed from a perspective facing a plane orthogonal to the rotation axis of the supply reel 32. In this case, the cutting portion 39 may include a cutting blade 39A and one arm portion 39B.

[0058] In addition, when the sticking body transfer tool 12 does not include the cutting portion 39, the sticking body 11 may have a plurality of cuts. The plurality of cuts may be arranged in the direction in which the strip-shaped sticking body 11 extends. Further, each cut extends from one end portion in the width direction of the sticking body 11 toward the other end portion and has a length that does not reach the other end portion.

[0059] When assembling the sticking body transfer unit 10 having the structure described with reference to FIGS. 2 and 3, first, an operator attaches the roll-shaped sticking body 11 to the supply reel 32. Next, the operator peels off a part of the release sheet 22 from the sticking tape 23 at the tip of the sticking body 11. Subsequently, the part of the release sheet 22 peeled off from the sticking tape 23 is wound around the take-up reel 33.

[0060] On the other hand, the operator aligns the laminate of the carrier sheet 21 and the sticking tape 23 in the sticking body 11 along the first conveyance reel 37. At this time, the operator changes the orientation of the laminate so that, after the first conveyance reel 37, the laminate is along the XY plane and the carrier sheet 21 is positioned on the front side of the paper surface with respect to the sticking tape 23.

[0061] Then, the operator aligns the laminate along the transfer portion 34 so that the transfer portion 34 is positioned on the front side of the paper surface with respect to the laminate. Subsequently, at the tip of the laminate, after peeling off a part of the carrier sheet 21 from the sticking tape 23, the operator aligns the carrier sheet 21 along the transfer portion 34 so that the carrier sheet 21 is positioned on the front side of the paper surface with respect to the transfer portion 34.

[0062] The operator further peels off the carrier sheet 21 from the sticking tape 23 and then aligns the carrier sheet 21 along the second conveyance reel 38. At this time, the operator changes the orientation of the carrier sheet 21 so that, after the second conveyance reel 38, the carrier sheet 21 is along a plane intersecting the YZ plane. Then, the operator winds the tip of the carrier sheet 21 around the take-up reel 33. Thereby, the sticking body transfer unit 10 is obtained.

[0063] According to such an adherend transfer unit 10, in conjunction with the user transferring the adhesive tape 23 to the skin at the transfer portion 34, a part of the carrier sheet 21 and a part of the release sheet 22 are wound around the take-up reel 33. Also, in conjunction with a part of the carrier sheet 21 and a part of the release sheet 22 being wound up, the laminate of the carrier sheet 21 and the adhesive tape 23 is newly supplied from the supply reel 32 toward the transfer portion 34.

[0064] As described above, according to the first embodiment of the adherend transfer unit and the adherend transfer tool, the following effects can be obtained. (1-1) It is possible to increase the degree of freedom in the length of the area to which the adhesive tape 23 is applied.

[0065] (1-2) When the adherend transfer tool 12 includes a cutting portion 39 capable of cutting the adhesive tape 23, even if the adhesive tape 23 includes a base material 23A having a high tensile breaking elongation, it is easy to make the length of the adhesive tape 23 attached to the skin an arbitrary length.

[0066] (1-3) By the adherend 11 satisfying both condition 1 and condition 2, only the adhesive tape 23 among the adherends 11 is likely to be transferred to the skin.

[0067] (1-4) When at least one of the base material 23A and the adhesive layer 23B contains an active ingredient, by attaching the adhesive tape 23 to the skin, it is possible to cause the active ingredient contained in at least one of the base material 23A and the adhesive layer 23B to act on the skin.

[0068] [Second Embodiment] Referring to FIG. 4, a second embodiment of the adherend transfer unit and the adherend transfer tool will be described. In the second embodiment, the difference from the first embodiment is that the adherend transfer tool is configured to be able to apply an active ingredient to the adhesive tape 23. Therefore, hereinafter, while explaining in detail the differences between the second embodiment and the first embodiment, for the configurations common to the first embodiment in the second embodiment, the same reference numerals as those used in the first embodiment will be used, and the description of the configuration will be omitted.

[0069] [Adherend Transfer Unit] Referring to FIG. 4, the adherend transfer unit will be described. As shown in FIG. 4, the adherend transfer tool 42 of the adherend transfer unit 40 further includes a switch 51, a storage portion 52, and an application portion 53 with respect to the adherend transfer tool 12 of the first embodiment. The switch 51 is exposed on the outer surface of the case 31. The storage portion 52 is configured to store a coating agent containing at least one active ingredient for the skin. The application portion 53 is configured to apply the coating agent to a portion of the adhesive layer 23B before the release sheet 22 is peeled off and before it is attached to the skin by operating the switch 51. According to the adherend transfer tool 42, by attaching the adhesive tape 23 to the skin using the adherend transfer tool 42, it is possible to position the coating agent between the adhesive layer 23B and the skin.

[0070] The switch 51 is attached to the main body portion 31A of the case 31 so as to be exposed from the main body portion 31A. Thereby, the user of the adherend transfer unit 40 can operate the switch 51. The switch 51 may be configured such that, for example, the user can press down the switch 51 and return to the state before being pressed down when the pressing force is released. Alternatively, the switch 51 may be configured such that, for example, the user can rotate it only in one direction around a rotation axis extending along the Z direction and return to the state before being rotated when the rotating force is released.

[0071] The coating agent contains the above-described active ingredient(s). The coating agent may contain only one kind of active ingredient or two or more kinds of active ingredients. The coating agent may be, for example, any one of a gel agent, an ointment agent, and a cream agent. The coating agent may contain a base in addition to the active ingredient. When the coating agent is a gel agent, the base may be a hydrogel. When the coating agent is an ointment agent, the base may be either an oily base or a water-soluble base. The oily base may be, for example, petrolatum. The water-soluble base may be, for example, macrogol. When the coating agent is a cream agent, the type of the base may be, for example, an oil-in-water type or a water-in-oil type.

[0072] The accommodating portion 52 is located within the main body portion 31A of the case 31. The accommodating portion 52 defines an accommodating space capable of accommodating the coating agent, thereby separating the accommodating space from the space 31S defined by the main body portion 31A. The accommodating portion 52 may be configured such that, for example, the inside of the accommodating space is pressurized by operating the switch 51, and thereby a predetermined amount of the coating agent is supplied to the applying portion 53. In this case, the accommodating portion 52 may have flexibility such that it is recessed by a predetermined amount, for example, by operating the switch 51.

[0073] The applying portion 53 applies the coating agent supplied from the accommodating portion 52 to the adhesive layer 23B of the sticking tape 23. In the path along which the laminate of the carrier sheet 21 and the sticking tape 23 is conveyed, the applying portion 53 is located between the first conveying reel 37 and the transfer portion 34. When viewed from a viewpoint facing the XY plane, the applying portion 53 is configured to be able to apply the coating agent within a range not exceeding the width of the adhesive layer 23B. For example, the applying portion 53 may have an opening on the surface facing the adhesive layer 23B and configured to discharge the coating agent within a range not exceeding the width of the adhesive layer 23B.

[0074] According to the applicator transfer tool 42 of the present embodiment, before the laminate of the carrier sheet 21 and the adhesive tape 23 is conveyed from the first conveyance reel 37 to the transfer unit 34, the application unit 53 applies an application agent to the adhesive layer 23B of the adhesive tape 23. Thereby, when the adhesive tape 23 is attached to the skin by the transfer unit 34, it is possible to position the application agent between the adhesive tape 23 and the skin.

[0075] In addition, as described above, in the adhesive tape 23 of the applicator 11, at least one of the base material 23A and the adhesive layer 23B may contain an active ingredient. When the adhesive tape 23 contains an active ingredient, the active ingredient contained in the adhesive tape 23 and the active ingredient contained in the application agent may be the same as each other or different from each other. When the active ingredient contained in the adhesive tape 23 and the active ingredient contained in the application agent are the same as each other, it is possible to apply an amount of the active ingredient that exceeds the amount that can be contained in the adhesive tape 23 and the application agent, respectively, to the skin. When the active ingredient contained in the adhesive tape 23 and the active ingredient contained in the application agent are different from each other, it is possible to obtain a synergistic effect between the active ingredient contained in the adhesive tape 23 and the active ingredient contained in the application agent.

[0076] As described above, according to the second embodiment of the applicator transfer unit and the applicator transfer tool, in addition to the effects (1-1) to (1-4) described above, the following effects can be obtained.

[0077] (2-1) By attaching the adhesive tape 23 to the skin using the applicator transfer tool 42, it is possible to position the application agent between the adhesive layer 23B and the skin.

[0078] [Test Example] With reference to FIG. 5, a test example will be described. [Test Example 1] Among a pair of mutually facing surfaces, a biaxially stretched polypropylene (OPP) film (manufactured by Futamura Chemical Co., Ltd., FOR-MP, thickness 40 μm) with one surface being a matte surface was prepared as a carrier sheet. Then, an aqueous polyurethane (manufactured by Mitsui Chemicals, Inc., Takelac WS-6021) (Takelac is a registered trademark) containing an ether-based polyol was coated on the matte surface of the OPP film, and then the aqueous polyurethane was dried to form a precursor layer. Next, the precursor layer was aged at room temperature to obtain a substrate having a thickness of 15 μm.

[0079] A release film (manufactured by Toray Film Processing Co., Ltd., Serapil WZ, thickness 75 μm) (Serapil is a registered trademark) composed of a PET film and a release layer formed from a silicone resin was prepared as a release sheet. Next, a urethane-based adhesive (manufactured by Toyochem Co., Ltd., SP-205) as the main agent and a curing agent (manufactured by Toyochem Co., Ltd., T-501B) were prepared. The curing agent was added to the main agent so that the ratio of the number of moles of isocyanate groups contained in the curing agent to the number of moles of hydroxyl groups contained in the main agent (number of moles of isocyanate groups / number of moles of hydroxyl groups) was 0.13. Then, a coating liquid for forming an adhesive layer was obtained by stirring the mixture of the main agent and the curing agent. The coating liquid was coated on the release film, and then the coating liquid was dried to obtain an adhesive layer having a thickness of 15 μm.

[0080] Then, by laminating the substrate and the adhesive layer, a laminate in which the OPP film, the adhesive tape, and the release film were laminated in the described order was obtained. Thus, the adherend of Test Example 1 was obtained.

[0081] [Test Example 2] In the adherend of Test Example 1, an adherend of Test Example 2 was obtained in the same manner as in Test Example 1, except that the OPP film was changed to a polyethylene terephthalate (PET) film (manufactured by Lintec Corporation, 6501 formulation, thickness 50 μm) subjected to a release treatment.

[0082] [Test Example 3] In the adherend of Test Example 1, an adherend of Test Example 3 was obtained in the same manner as in Test Example 1, except that the OPP film was changed to a polyethylene terephthalate (PET) film (manufactured by Toray Industries, Inc., S10, thickness 50 μm).

[0083] [Test Example 4] In the adherend of Test Example 1, an adherend of Test Example 4 was obtained in the same manner as in Test Example 1, except that the OPP film was changed to a polyethylene terephthalate (PET) film (manufactured by Lintec Corporation, 6050 formulation, thickness 50 μm) subjected to a release treatment.

[0084] [Test Example 5] In the adherend of Test Example 1, a PVDF film having a thickness of 50 μm was formed by extrusion molding using polyvinylidene fluoride resin (PVDF) (manufactured by Arkema Inc., Kynar FLEX2500) (Kynar is a registered trademark) instead of the OPP film. Otherwise, an adherend of Test Example 5 was obtained in the same manner as in Test Example 1.

[0085] [Test Example 6] In the adherend of Test Example 1, an adherend of Test Example 6 was obtained in the same manner as in Test Example 1, except that the ratio of the number of moles of isocyanate groups contained in the curing agent to the number of moles of hydroxyl groups contained in the main agent was changed to 0.25.

[0086] [Test Example 7] In the adherend of Test Example 1, petrolatum (manufactured by Daiyo Pharmaceutical Co., Ltd., Petrolatum HG) was further added to the coating liquid for forming the adhesive. At this time, the weight of the petrolatum was set to 40% with respect to the solid content of the main agent. Otherwise, an adherend of Test Example 7 was obtained in the same manner as in Test Example 1.

[0087] [Evaluation Method] [Peel Strength between Carrier Sheet and Substrate] The peel strength of the base material with respect to the carrier sheet was measured by a method conforming to JIS Z 0237:2009 "Test Methods for Adhesive Tapes and Adhesive Sheets". A universal testing machine (Autograph AGS-X load cell 5 kN, manufactured by Shimadzu Corporation) was used for the measurement of the peel strength. When measuring the peel strength, test pieces having a width of 25 mm were prepared from each adherend. Then, the base material was fixed to the universal testing machine, and subsequently, the strength when the carrier sheet was peeled from the base material at 180° was calculated. At this time, the test speed of the universal testing machine was set to 300 mm / min.

[0088] In addition, five test pieces were prepared for each test example, and the 180° peel strength was measured for each test piece. Then, the average value of the peel strengths of the five test pieces was calculated, and the average value was set as the 180° peel strength of each test example.

[0089] [Peel Strength of Adhesive Layer] The peel strength of the adhesive layer was measured by a method conforming to JIS Z 0237:2009 "Test Methods for Adhesive Tapes and Adhesive Sheets". A universal testing machine (the same as above) was used for the measurement of the peel strength. When measuring the peel strength, an SUS plate formed from SUS304 with a BA surface finish was prepared. Also, test pieces having a width of 25 mm were prepared from the adhesive layer of each test example. Then, after bringing the adhesive layer into contact with the SUS plate, the adhesive layer was pressure-bonded to the SUS plate using a 2 kg rubber roller. Next, using the universal testing machine, the strength when the test piece was peeled from the SUS plate at 180° was calculated. At this time, the test speed of the universal testing machine was set to 300 mm / min.

[0090] In addition, five test pieces were prepared for each test example, and the peel strength was measured for each test piece. Then, the average value of the peel strengths of the five test pieces was calculated, and the average value was set as the peel strength of each test example.

[0091] [Attachment to Skin] After processing the adherend into a strip shape having a width of 10 mm, a roll-shaped adherend was obtained by winding the adherend so that the carrier sheet was positioned on the outer surface of the adherend. Next, an adherend transfer tool having the structure described in the first embodiment was prepared. Then, the adherend was attached to the adherend transfer tool.

[0092] When the adhesive tape was wound around a finger using the adherend transfer tool, the state of the adhesive tape was evaluated at the following two levels. ○: The adhesive tape can be attached to the finger without causing wrinkles in the adhesive tape. △: It is possible to attach the adhesive tape to the finger, but wrinkles occur in the adhesive tape.

[0093] [Evaluation Results] The evaluation results for the adherends of each test example were as shown in FIG. 5. As shown in FIG. 5, it was confirmed that the 180° peel strength between the carrier sheet and the base material was 85.1 mN / 25 mm in Test Example 1, 81.0 mN / 25 mm in Test Example 2, and 492.0 mN / 25 mm in Test Example 3. The 180° peel strength between the carrier sheet and the base material was 579.0 mN / 25 mm in Test Example 4, 716.9 mN / 25 mm in Test Example 5, 78.2 mN / 25 mm in Test Example 6, and 98.1 mN / 25 mm in Test Example 7.

[0094] The 180° peel strength of the adhesive layer was found to be 3.2 N / 25 mm in Test Examples 1 and 3, 3.3 N / 25 mm in Test Examples 2 and 5, and 3.4 N in Test Example 4. The 180° peel strength of the adhesive layer was found to be 0.8 N / 25 mm in Test Example 6 and 4.0 N / 25 mm in Test Example 7.

[0095] Skin adhesion was found to be "○" in Test Examples 1 to 37 and "△" in Test Examples 4 to 6. From these results, when transferring the adherend to the skin using the adherend transfer tool, from the perspective of suppressing wrinkles generated in the adhesive tape, it is preferable that the 180° peel strength between the carrier sheet and the base material is less than the value in Test Example 4. Also, if it is 492.0 mN / 25 mm or less, it can be said that the certainty of suppressing wrinkles is enhanced.

[0096] Also, when transferring the adherend to the skin using the adherend transfer tool, from the perspective of suppressing wrinkles generated in the adhesive tape, it is preferable that the 180° peel strength of the adhesive layer exceeds the value in Comparative Example 6. If it is 3.2 N / 25 mm or more, it can be said that the certainty of suppressing wrinkles is enhanced.

[0097] In Test Examples 4 and 5, since the 180° peel strength between the carrier sheet and the base material is large, it is difficult for the carrier sheet to peel off from the base material during the transfer of the adhesive tape, and thus it can be said that wrinkles are generated in the adhesive tape. On the other hand, in Test Example 6, since the 180° peel strength of the adhesive layer is small, when the adhesive tape is transferred to the skin, the adhesive tape is likely to shift on the skin, and thus it can be said that wrinkles are generated in the adhesive tape.

[0098] In addition, each of the above-described embodiments can be implemented with the following modifications. [Take-up roller] · As shown in FIG. 6, the adherend transfer tool 12 of the first embodiment may separately include a first take-up reel 33A for winding the release sheet 22 and a second take-up reel 33B for winding the carrier sheet 21. In this case, the adherend transfer tool 12 further includes a first take-up gear 36A and a second take-up gear 36B. The first take-up gear 36A is configured to rotate together with the first take-up reel 33A. The second take-up gear 36B is configured to rotate together with the second take-up reel 33B.

[0099] In the example shown in FIG. 6, when viewed from a perspective facing the XY plane, a second take-up reel 33B is positioned between the supply reel 32 and the first take-up reel 33A. The second take-up gear 36B is configured to mesh with the supply gear 35 and the first take-up gear 36A. The second take-up reel 33B rotates clockwise, causing the second take-up gear 36B to rotate clockwise. The supply reel 32 and the first take-up reel 33A each rotate counterclockwise, causing the supply gear 35 and the first take-up gear 36A to each rotate counterclockwise.

[0100] When the adherend 11 is attached to the adherend transfer device 12, in the Z direction, the adherend 11 is positioned in front of the supply gear 35. The first take-up reel 33A takes up the release sheet 22 in front of the first take-up gear 36A in the Z direction. The second take-up reel 33B takes up the carrier sheet 21 in front of the second take-up gear 36B in the Z direction.

[0101] In this modified example, the second conveyance reel 38 is positioned between the transfer unit 34 and the second take-up reel 33B in the conveyance path of the carrier sheet 21. When assembling the adherend transfer unit 10, first, an operator attaches the roll-shaped adherend 11 to the supply reel 32. Next, the operator peels a part of the release sheet 22 from the adhesive tape 23 at the tip of the roll-shaped adherend 11. Subsequently, the part of the release sheet 22 peeled from the adhesive tape 23 is wound around the first take-up reel 33A.

[0102] On the other hand, the operator aligns the laminate of the carrier sheet 21 and the adhesive tape 23 of the adherend 11 along the first conveyance reel 37. Subsequently, the operator aligns the laminate along the transfer unit 34 such that the transfer unit 34 is positioned in front of the laminate on the paper surface. Then, at the tip of the laminate, after peeling the carrier sheet 21 from the adhesive tape 23, the operator aligns the carrier sheet 21 along the transfer unit 34 such that the carrier sheet 21 is positioned in front of the transfer unit 34 on the paper surface.

[0103] The operator further peels the carrier sheet 21 from the adhesive tape 23, and then guides the carrier sheet 21 along the second conveyance reel 38. Then, the operator winds the leading end of the carrier sheet 21 around the second take-up reel 33B. Thereby, the adherend transfer unit 10 is obtained.

[0104] According to such an adherend transfer unit 10, in conjunction with the user transferring the adhesive tape 23 onto the skin at the transfer portion 34, a part of the release sheet 22 is wound around the first take-up reel 33A, and a part of the carrier sheet 21 is wound around the second take-up reel 33B. Further, in conjunction with a part of the carrier sheet 21 and a part of the release sheet 22 being wound up, the laminate of the carrier sheet 21 and the adhesive tape 23 is newly supplied from the supply reel 32 toward the transfer portion 34.

[0105] Note that, when viewed from a viewpoint facing the XY plane, the first take-up reel 33A may be positioned between the supply reel 32 and the second take-up reel 33B. In this case, the first take-up gear 36A is configured to mesh with the supply gear 35 and the second take-up gear 36B. The first take-up reel 33A rotates clockwise, whereby the first take-up gear 36A rotates clockwise. The supply reel 32 and the second take-up reel 33B each rotate counterclockwise, whereby the supply gear 35 and the second take-up gear 36B each rotate counterclockwise.

[0106] Further, the configuration of the modification shown in FIG. 6 may be combined with the adherend transfer tool 42 of the second embodiment. That is, the adherend transfer tool 42 of the second embodiment may include two take-up reels 33A and 33B and two take-up gears 36A and 36B.

[0107] [Adherend transfer tool] · The sticking body transfer tools 12 and 42 of each embodiment may be configured to draw out the sticking tape 23 along the ZY plane. In this case, for example, the transfer part 34 may be configured to have a substantially triangular shape along the XY plane and the cross section to be continuous along the Z direction. Also, the first conveyance reel 37 may be configured to convey the laminate of the carrier sheet 21 and the sticking tape 23 along the ZY plane, and the second conveyance reel 38 may be configured to convey the carrier sheet 21 along the ZY plane.
