Description

  The present invention relates to a deployable wearing article including a fastening tape and a target tape such as a deployable disposable diaper.

  The unfoldable disposable diaper usually has an abdominal side portion arranged on the wearer's ventral side, a dorsal side portion arranged on the dorsal side, and a crotch portion positioned therebetween, and when wearing this The side flap of the back side is extended to the wearer's ventral side, and the fastening tape provided on the side flap is fastened to the outer surface of the ventral side. Accordingly, the diaper can be appropriately tightened around the waist and fixed so as not to slip off. As this fastening tape, the fastening tape which enables the mechanical joining which can be fixed and peeled freely is widely used. The fastening tape generally has a planar mechanical fastener, for example, a structure in which this is attached to a diaper flap together with a base sheet. As this mechanical fastener, a so-called male material, which is a planar fastener having a number of engagement hooks having a shape capable of engaging with a fiber or the like, for example, a hook shape or a mushroom shape, is used. On the other hand, the part that receives this planar mechanical fastener on the outer surface of the ventral side of the diaper may be left as it is when the outer surface is formed of a non-woven fabric. In order to realize the hooking, for example, a target tape having a loop-like or fluffy surface fiber structure, so-called female material is used.

  For example, Patent Document 1 discloses a fastening tape and a deployable disposable diaper having a target tape to which the fastening tape is fastened. In order to be able to express a sufficient fastening force each time, a non-woven fabric composed of a specific composite fiber is used as a target tape, and the target tape is embossed in a zigzag shape in the width direction of the diaper. Forming the part. Further, Patent Document 2 discloses an adhesive formed by printing a design on the outer surface of a target tape made of a nonwoven fabric and bonding the constituent fibers of the nonwoven fabric to the outer surface for the purpose of improving the visibility of the design. It is described that the line is formed in a wave shape extending in the width direction of the diaper. Further, in Patent Document 3, there is a problem that fuzzing is large when an air-through nonwoven fabric is used as a target tape having a high engagement force with a fastening tape provided with a mechanical fastener. To solve this problem, an air-through nonwoven fabric is used. It is described that an embossed portion having a predetermined pattern such as a lattice shape or a wave shape or a straight shape extending in the diaper width direction is formed on the outer surface of the target tape.

  The diaper 1 has both side edges along the vertical direction X curved in an inward arc shape in the central portion of the vertical direction X including the crotch portion 1M, and in the plan view as shown in FIG. The section is in the shape of an hourglass with an inner part. The crotch part 1M includes an excretion part facing part (not shown) that is disposed to face the excretion part of the wearer when worn. The excretory part opposing part is normally in a position biased slightly closer to the back side part 1R than the central part in the longitudinal direction X of the diaper 1.

  The diaper 1 is a liquid-retaining absorbent body 4, a liquid-permeable surface sheet 2 that is disposed on the skin-facing surface side of the absorbent body 4 and that can contact the skin of the wearer when worn, and the absorbent body 4. And a liquid-impermeable or water-repellent back sheet 3 disposed on the non-skin facing surface side. The diaper 1 has a vertically long shape in the longitudinal direction X in plan view as shown in FIG. 1, the longitudinal direction thereof coincides with the longitudinal direction X, and the width direction thereof coincides with the lateral direction Y.

  In the present specification, the “skin-facing surface” is a surface of the wearing article or its constituent member (for example, the absorbent body 4) that is directed toward the wearer's skin when the wearing article is worn, that is, relative to the wearer's skin. The side close to the skin, and the “non-skin facing surface” is the surface of the worn article or its component that is directed to the side opposite to the skin side when the worn article is worn, that is, the side that is relatively far from the wearer's skin. It is. In addition, "at the time of wearing" here means the state in which the normal proper wearing position is maintained, and does not include the case where the worn article is in a state deviated from the proper wearing position.

  Each of the top sheet 2 and the back sheet 3 has a size larger than that of the absorber 4, extends outward from the peripheral edge of the absorber 4, and is joined to each other at the extending portion. Each of the top sheet 2 and the back sheet 3 forms the outer shape of the diaper 1 in the unfolded and stretched state as shown in FIG. As the top sheet 2 and the back sheet 3, various types conventionally used for this type of absorbent article can be used without particular limitation. For example, various nonwoven fabrics or apertured films can be used as the top sheet 2, and a resin film, a laminate of a resin film and a nonwoven fabric, or the like can be used as the back sheet 3. The back sheet 3 includes, for example, a form in which a liquid-impermeable film sheet alone and a form in which nonwoven fabrics as exterior sheets are laminated and disposed on the non-skin facing surface side of the film sheet. In the plan view as shown in FIG. 1, the absorbent body 4 has an hourglass shape in which a central portion in the longitudinal direction X located at the crotch portion 1M is inwardly bound, and has a vertically long shape that is long in the longitudinal direction X. . As the absorbent body 4, for example, an absorbent core containing particles of water-absorbing polymer and at least one fiber material such as pulp fiber can be used, and the absorbent core has a core made of paper, nonwoven fabric or the like on the surface. It may be covered with a wrap sheet.

  A waist gather forming elastic member 5 for fitting the waist portion 11 to the wearer's body is provided on the waist portion 11 which is an end portion in the longitudinal direction X of each of the ventral side portion 1F and the back side portion 1R. It is fixed between the top sheet 2 and the back sheet 3 in a stretched state in Y, whereby a waist gather is formed in the waist portion 11 by contraction of the elastic member 5 when the diaper 1 is worn. In addition, leg gathers for fitting the leg portions 12 to the wearer's body are provided on the left and right leg portions 12 including side edges along the longitudinal direction X of the crotch 1M. The forming elastic member 6 is fixed between the top sheet 2 and the back sheet 3 in a stretched state in the longitudinal direction X, whereby the leg member 12 is contracted by the elastic member 6 when the diaper 1 is worn. Leg gathers are thus formed. The top sheet 2, the back sheet 3, the absorber 4, and the elastic members 5 and 6 are joined to each other by a known joining means such as a hot-melt adhesive.

  As shown in FIG.1 and FIG.2, a pair of fastening tapes 7 and 7 are provided on both side edges along the longitudinal direction X of the back side 1R. Moreover, the target tape 8 to which the fastening area | region 72 mentioned later of a fastening tape is fastened is provided in the outer surface, ie, non-skin opposing surface, of the belly side part 1F of the diaper 1. FIG.

  In FIG. 3, only one of the pair of fastening tapes 7 and 7 is shown enlarged, but unless otherwise specified, the other fastening tape 7 not shown in FIG. 3 is also shown in FIG. It is configured in the same way. As shown in FIG. 3, the fastening tape 7 includes a fixing region 70 fixed to the back side portion 1 </ b> R, and other members that are adjacent to the fixing region 70 and extend outward in the lateral direction Y from the fixing region 70. And a non-fixed free region 71. The fixing region 70 is fixed to a side flap portion that is an extended portion from a side edge along the longitudinal direction X of the absorbent body 4 of each of the top sheet 2 and the back sheet 3, and more specifically, the side flap. It is interposed between both sheets 2 and 3 constituting the part. The fixing region 70 is fixed to the side flap portion by a known joining means such as an adhesive or heat seal.

  One surface on the outer side in the lateral direction Y of the free region 71 of the fastening tape 7, more specifically, the to-be-bonded surface overlapped with the target tape 8 when the diaper 1 is worn is a fastening region having a fastening member. 72. As shown in FIG. 3, the fastening region 72 has a quadrangular shape in plan view and extends in the horizontal direction Y, and is connected to each of the pair of horizontal sides 7 y and 7 y in the vertical direction X. And a vertical side 7x. The vertical side 7x is a front end of the fastening tape 7 (free region 71) on the outer side in the horizontal direction Y. In the present invention, the quadrangular shape is a concept including not only a square in a strict sense such as a square or a rectangle, but also a shape with rounded corners, a trapezoid, a rhombus, and the like.

  In the present embodiment, the fastening region 72 has a trapezoidal shape in plan view, more specifically, an isosceles trapezoidal shape, and has a relatively long length among two bottom sides having different lengths in the isosceles trapezoid. The short base is the vertical side 7x. The pair of horizontal sides 7y, 7y of the fastening region 72 extends in a direction intersecting both the vertical direction X and the horizontal direction Y. The fastening region 72 gradually decreases in length or width in the lateral direction as it goes outward in the lateral direction Y.

  At least a peripheral portion of the fastening region 72, more specifically, a region within 5 mm from each of the vertical side 7x and the pair of horizontal sides 7y, 7y of the fastening region 72 is a fastening portion 73 in which a fastening member is disposed. It has become. In the present embodiment, as shown in FIG. 3, the fastening members are arranged over the entire fastening region 72, and the whole fastening region 72 is a fastening portion 73. In the present embodiment, a male member of a planar mechanical fastener having a large number of engaging hooks is employed as the fastening member disposed in the fastening portion 73. The fastening member typically includes a sheet-like support and a plurality of engagement hooks provided on the surface of the support. The shape of the engagement hook is not particularly limited, and for example, various types of engagement hooks such as a pin type, a saddle type, a hook type, and a mushroom type can be used.

The length of the fastening region 72 of the fastening tape 7 in the lateral direction Y, that is, the farthest from the vertical side 7x (the front end of the fastening tape 7 in the lateral direction Y) and the vertical side 7x of the fastening part 73. The separation distance from the portion is preferably 10 mm or more, more preferably 20 mm or more, and preferably 150 mm or less, more preferably 100 mm or less, more specifically, preferably 10 mm or more and 150 mm or less, more preferably 20 mm or more. 100 mm or less.
Further, the length or width of the fastening region 72 in the longitudinal direction X is preferably 10 mm or more, more preferably 20 mm or more, and preferably 100 mm or less, more preferably 70 mm or less, more specifically preferably 10 mm. It is 100 mm or less, more preferably 20 mm or more and 70 mm or less. When the width | variety of the fixation area | region 72 is not constant like this embodiment, it is preferable that both the maximum value and the minimum value of the width exist in the said range.

  The target tape 8 has a rectangular shape in plan view as shown in FIG. 1, and the non-skin facing surface of the back sheet 3 that forms the non-skin facing surface of the abdominal side portion 1F with its longitudinal direction aligned with the lateral direction Y. Further, it is fixed by a known joining means such as an adhesive or heat seal. As shown in FIGS. 2 and 3, the surface of the target tape 8, that is, the surface to which the fastening region 72 of the fastening tape 7 is fastened, is a plan view in which the fastening portion 73 of the fastening region 72 can be fastened. The linear to-be-attached part 83 is formed so as to extend in the lateral direction Y, and the non-to-be-attached part 84 in a straight line in plan view in which the attaching part 73 cannot be attached is a to-be-attached part. It is formed to extend in the same direction as 83, that is, in the lateral direction Y. That is, the longitudinal direction of the to-be-attached part 83 and the non-to-be-attached part 84 corresponds to the horizontal direction Y, and the width direction corresponds to the longitudinal direction X.

  The to-be-attached part 83 of the target tape 8 is provided with a loop material that can be engaged with an engaging hook as a fastening member of the fastening part 73 in the fastening region 72 of the fastening tape 7. The to-be-fixed part 83 is configured to be able to detachably attach the attaching region 72 (attaching part 73). On the other hand, such a loop material is not arranged on the non-fixed portion 84 of the target tape 8, and therefore, the non-bonded portion 84 has a fixed region 72 (fixed portion 73) stopped. It cannot be worn. As the to-be-fixed part 83, the well-known female material which has a loop-shaped or fluffy surface fiber structure can be used, For example, various nonwoven fabrics, such as a spun bond nonwoven fabric, can be used. As the non-fixed part 84, for example, a female material that can be used as the fixed part 83 is subjected to a heat and pressure process such as heat embossing. When heat embossing is applied to a non-woven fabric as a female material, the processed fiber of the non-woven fabric functioning as a loop material melts into a film, and the fastening portion 73 of the fastening tape 7 cannot be fastened. It becomes a non-fixed part 84. Accordingly, as the target tape 8, a sheet material that can be used as a female material such as a spunbond nonwoven fabric can be used which is partially heated and pressurized. In this case, the heated and pressurized treatment is applied. The part which is not attached becomes the part to be secured 83, and the part which has been subjected to the heating and pressurizing process becomes the non-part to be secured 84.

  As shown in FIGS. 3 and 4, the target tape 8 has a plurality of to-be-attached portions 83 and a plurality of non-to-be-attached portions 84 alternately in the width direction, that is, the longitudinal direction X perpendicular to the longitudinal direction. It is arranged. That is, in the target tape 8, a plurality of to-be-attached portions 83 and a plurality of non-to-be-attached portions 84 extend alternately in the vertical direction X in the horizontal direction Y in a stripe shape. Further, as described above, the plurality of to-be-attached portions 83 and the plurality of to-be-attached portions 84 alternately extend in a stripe shape, so that the target tape 8 has the to-be-attached portions 83 and the sandwiched portions 83 sandwiched therebetween. A knob forming portion 85 is formed which includes non-sticking portions 84 and 84 positioned on both sides in the lateral direction Y (the width direction of the sticking portion 83 and the non-sticking portion 83). Thus, since the knob | pick part formation part 85 is comprised from the two non-adhering parts 84 and 84 and the one to-be-adhered part 83 interposed between them, it shows in FIG. Thus, in the form including four to-be-attached parts 83 and three to-be-attached parts 84, two knob part forming parts 85 are formed.

  In the present embodiment, as described above, the fastening is performed on the assumption that the longitudinal direction of the to-be-attached portion 83 and the non-to-be-attached portion 84 of the target tape 8 in a straight line in plan view coincides with the lateral direction Y. The vertical side 7x of the fastening region 72 of the tape 7 (the front end on the outer side in the horizontal direction Y of the fastening tape 7) is longer in the vertical direction X than the knob portion forming portion 85. That is, as shown in FIG. 4, the vertical length 7xL of the vertical side 7x of the fastening region 72 is longer than the vertical length 85L of the knob portion forming portion 85. In the present embodiment, the fastening tape 7 and the target tape 8 are particularly employed to remove the fastening tape 7 from the target tape 8 due to a wearer's misoperation or mischief as described below. It is hard to produce.

  That is, if at least the peripheral edge of the fastening region 72 is the fastening portion 73, the entire surface of the target tape 8 is a fastened portion 83 that can fasten the fastening portion 73. In the state where the fastening region 72 is fastened to the target tape 8, it is difficult for the peripheral portion of the fastening region 72 to float or turn over from the surface of the target tape 8. Since it becomes difficult to insert a finger between the two, it is possible to effectively prevent peeling of the fastening region 72 due to a wearer's erroneous operation or mischief.

  However, if the entire peripheral edge of the fastening region 72 is fastened to the target tape 8 in this way, the fastening region 72 (free region 71) is picked up by fingers from the fastened state and peeled off from the target tape 8. It becomes difficult to do so, and the operability when attaching and detaching the diaper 1 may be reduced.

  Therefore, in the present embodiment, in addition to the peripheral portion of the fastening region 72 as the fastening portion 73, the fastening portion 73 can be fastened to the target tape 8 to which the fastening region 72 is fastened. By disposing the fixed part 83 and the non-fixed part 84 in which the fixing part 73 cannot be fixed in a specific pattern, the fixing region 72 can be easily peeled off from the target tape 8. . More specifically, as shown in FIGS. 3 and 4, a plurality of to-be-attached portions 83 and a plurality of to-be-attached portions 84 are alternately formed in a stripe shape in the horizontal direction Y in the vertical direction X. The target tape 8 is formed with a knob portion forming portion 85 including two non-sticking portions 84 and 84 and a single sticking portion 83 interposed between them. Between the portion forming portion 85 and the vertical side 7x of the fastening region 72 that can function as a pick portion, a size relationship of “the vertical length 7xL of the vertical side 7x> the vertical length 85L of the pick portion forming portion 85”. By establishing this, the peelability of the fastening region 72 (free region 71) from the target tape 8 is improved.

  That is, between the vertical side 7x of the fastening region 72 of the fastening tape 7 and the knob forming part 85 of the target tape 8, the vertical length 7xL of the vertical side 7x> the vertical length of the knob forming part 85. Since the size relationship of 85L is established, in the state where the fastening region 72 is fastened to the target tape 8, the tip portion along the vertical side 7x of the fastening region 72 is always non-sticky. Since the portion 84 and the to-be-attached portions 83 and 83 located on both sides in the width direction, that is, the longitudinal direction X are fastened so as to straddle the longitudinal direction X, the leading end portion of the fastening region 72 and the target tape 8 As shown in FIG. 4, a single non-adhering portion 84 defined by the tip portion and a pair of adhering portions 83 and 83 spaced apart in the longitudinal direction X is provided. A space portion is formed.

  Therefore, when peeling the fastening region 72 (free region 71) from the target tape 8, first, fingers are inserted into the space portion formed in the vicinity of the tip portion along the vertical side 7x of the fastening region 72, The tip of the fastening region 72 including the vertical side 7x is peeled off from the target tape 8, and then the peeled portion is picked up with fingers and peeled in earnest. The fastening is performed by such a two-step peeling operation. The entire region 72 can be easily peeled off from the target tape 8. As described above, the non-fixed portion 84 of the target tape 8 is a knob portion (a tip along the vertical side 7x of the fixed region 72) used when peeling the fixed region 72 (free region 71) from the target tape 8. Part) to form a “temporary picking part”.

  As shown in FIG. 5, between the vertical side 7x of the fastening region 72 of the fastening tape 7 and the knob portion forming portion 85 of the target tape 8, the magnitude relationship opposite to that described above, that is, the knob portion forming portion. When the size relationship of 85 vertical length 85L> longitudinal length 7x vertical length 7xL is established, the fixing region 72 is fixed in the state where the fixing region 72 is fixed to the target tape 8. The front end portion along the vertical side 7x is necessarily fixed so as to straddle the non-fixed portion 84 and the fixed portions 83, 83 located on both sides in the width direction, that is, the vertical direction X, in the vertical direction X. Therefore, the temporary picking part (a space part composed of one non-stick part 84) is not necessarily formed, and therefore, the fastening area 72 (free area 71) is peeled off from the target tape 8. May decrease.

  The width of the non-sticking portion 84, that is, the length in the width direction orthogonal to the longitudinal direction of the non-sticking portion 84 is preferably 5 mm or more, more preferably 10 mm or more, and preferably 30 mm or less, more preferably 20 mm or less, more specifically, preferably 5 mm or more and 30 mm or less, more preferably 10 mm or more and 20 mm or less. If the width of the non-adhered portion 84 is too short, the function as the temporary picking portion described above may be deteriorated. If the width of the non-adhered portion 84 is too long, the fixing region 72 with respect to the target tape 8 may be reduced. There is a possibility that the fastening force is reduced and the fastening region 72 (free region 71) is turned over during fastening.

  In the target tape 8, the to-be-attached portion 83 and the non-to-be-attached portion 84 have a width (the longitudinal direction X in the present embodiment in which the longitudinal direction of the to-be-attached portion 83 and the non-to-be-attached portion 84 is the lateral direction Y). Are preferably the same, or the secured portion 83 is longer than the unsecured portion 84.

  If the widths of the secured portion 83 and the unsecured portion 84 are different from each other, the secured region 72 is secured to the target tape 8 depending on the width of the secured portion 83 and the unsecured portion 84. Since the case where the temporary picking part which consists of the part 84 may not be formed may arise, from the viewpoint of making the formation of the temporary picking part more reliable, the width of each of the attached part 83 and the non-attached part 84 is Preferably they are the same.

  In addition, if the secured portion 83 is wider than the unsecured portion 84, the secured region 83 is fixed to the vertical side 7 x of the secured region 72 when the secured region 72 is secured to the target tape 8. When the end in the length direction of the leading end (corner of the fastening region 72) corresponds to the non-sticking portion 84 of the target tape 8, the fastening region 72 (free) starts from the corner of the fastening region 72. The inconvenience that the area 71) is turned over can be effectively prevented. When making the width of the to-be-attached part 83 longer than that of the non-to-be-attached part 84, the ratio between the width of the to-be-attached part 83 and the width of the non-to-be-attached part 84 is preferably the former / the latter. 1.1, more preferably 1.5 or more, and preferably 3 or less, more preferably 2 or less, more specifically preferably 1.1 or more and 3 or less, more preferably 1.5 or more and 2 or less. It is.

  In order to improve the peelability of the fastening region 72 from the target tape 8, the setting of the extending direction, that is, the longitudinal direction of the secured portion 83 and the non-secured portion 84 of the target tape 8 is also an important factor. Temporarily, in the target tape 8, when the to-be-attached part 83 and the non-to-be-attached part 84 extend in a direction intersecting both the longitudinal direction X and the transverse direction Y as shown in FIG. The depth D2 in the insertion direction of the fingers, that is, the lateral direction Y, is adjacent to the space portion formed of the non-fixed portion 84 that functions as the temporary picking portion in the state where the fixing region 72 is fixed to the target tape 8. Then, due to the influence of the to-be-fixed portion 83 that is inclined in the direction intersecting both the vertical direction X and the horizontal direction Y, there is a possibility that the fingers cannot be inserted sufficiently. On the other hand, when the to-be-attached part 83 and the non-to-be-attached part 84 are extended in the horizontal direction Y like this embodiment, as shown to Fig.6 (a), it functions as the said temporary picking part. Since the depth D1 in the lateral direction Y of the space portion composed of the non-fixed portion 84 is not limited by the fixed portion 83 adjacent thereto, the two-stage peeling operation of the above-described fixed region 72 is performed. It can be done smoothly.

  Further, the fastening strength of the fastening portion 73 in the fastening region 72 with respect to the target tape 8 is such that the outer edge portion of the fastening region 72 along the vertical side 7x or the horizontal side 7y is positioned more inward than the outer edge portion. It is preferable that it is smaller than the inner edge portion of the fastening region 72 to be fixed. Since the outer edge portion of the fastening region 72 is a portion to be peeled first when the fastening region 72 is peeled off from the state where the fastening region 72 is fastened to the target tape 8, the peeling of the fastening region 72 is achieved by such a configuration. Becomes easier. In addition, from the viewpoint of preventing the peeling of the fastening tape due to a wearer's misoperation or mischief, it is preferable that the width of the non-sticking portion 84 of the target tape 8 functioning as the temporary picking portion is as short as possible. Since the fastening force of the fastening part 73 at the outer edge part of the fastening area 72 is weaker than that of the inner edge part as described above, the peeling of the fastening area 72 using this temporary picking part becomes easier. It becomes possible to set the width | variety of the non-sticking part 84 short. In the present embodiment, as described above, since the temporary picking portion is formed at the tip portion along the vertical side 7x of the fastening region 72, at least at the tip portion along the vertical side 7x of the fastening region 72, It is only necessary that the fastening strength of the fastening portion 73 to the target tape 8 is smaller at the inner edge portion than at the outer edge portion. As described above, as a method of making the fastening strength of the fastening portion 73 to the target tape 8 different between the outer edge portion and the inner edge portion of the fastening region 72, two kinds of fastening members (for example, engagement members having different fastening strengths) are used. A male member of a planar mechanical fastener having a number of joint hooks), and of the two types of fastening members, a fastening member having a relatively high fastening strength is disposed on the outer edge of the fastening region 72, and In particular, there is a method in which a fastening member having a low fastening strength is disposed on the inner edge of the fastening region 72.

  In the target tape 8 </ b> A shown in FIG. 7, the longitudinal direction of the to-be-attached portion 83 and the non-to-be-attached portion 84 matches the longitudinal direction X, and the width direction matches the transverse direction Y. Thus, when the longitudinal direction of the to-be-fixed part 83 and the non-to-be-attached part 84 corresponds to the vertical direction X, the horizontal side 7y of the fastening area | region 72 in the fastening tape 7 is compared with the knob | pick part formation part 85. And the length of the horizontal direction Y is long. That is, as shown in FIG. 7, the lateral length (projection length) 7yL of the lateral side 7y of the fastening region 72 is larger than the lateral length (projection length) 85L of the knob forming portion 85. long. With such a configuration, in the state where the fastening region 72 is fastened to the target tape 8A, the edge portion along the horizontal side 7y of the fastening region 72 is always the non-sticking portion 84 and its width direction, that is, the lateral direction. Since the fixing portions 83 and 83 located on both sides of the direction Y are fixed so as to straddle the horizontal direction Y, between the edge portion along the horizontal side 7 y of the fixing region 72 and the target tape 8. Is formed of a single non-fixed portion 84 defined by the edge and a pair of fixed portions 83 and 83 spaced apart in the lateral direction Y. Functions as the temporary picking portion. As described above, in the embodiment shown in FIG. 7, the longitudinal direction of the fastening part 83 and the non-sticking part 84 coincides with the vertical direction X, and thus the temporary picking part (one non-sticking part) 7) is formed in the vicinity of the edge portion along the lateral side 7y of the fastening region 72. The effect produced by the embodiment shown in FIG. 7 is the effect of the diaper 1 described above. The same.

  Although the present invention has been described above, the present invention is not limited to the above-described embodiments and can be modified as appropriate.
