Description

  The present invention relates to absorbent articles such as disposable diapers and absorbent pads for the purpose of preventing pressure sores (bed slip).

Pressure ulcers tend to occur in people who are bedridden, those who cannot use their wheelchairs, or who cannot change their body orientation or position, especially in areas where bones are raised and subject to pressure, such as the waist and hips. This is likely to occur. Here, the direct cause of pressure ulcers is the cessation of blood flow due to local pressure, but if the skin is left exposed to moisture such as urine and stool for a long time, the surface of the skin becomes weak and damaged. As a result, the pressure ulcer is likely to occur.
Japanese Patent No. 3764010 Japanese Patent No. 3685874

  However, in the conventional absorbent article, at the time of urination, the sacral region and the coccyx region where the coccyx portion where the pressure ulcer easily occurs are wet with the urine, and the pressure ulcer is easily generated. More specifically, in the conventional absorbent article, a gap is easily created between the body and the article in the crotch region. In particular, since an absorbent article that has absorbed urine is pulled downward under its own weight, such a gap is inevitable. In addition, such a gap is rather preferable from the viewpoint of using up the entire absorbent body by spreading urine over all of the absorbent body existing in substantially the whole from the ventral side to the back side.

  However, the design philosophy of liquid diffusion in such a normal absorbent article may be revealed. In other words, the conventional absorbent article has a structure in which the body's urination opening and the crotch part of the absorbent article are separated from each other. There was a risk of causing skin troubles.

  On the other hand, in some cases, absorbent articles are generally affixed and fixed to the inside of a paper diaper with a fastener, an adhesive portion, or the like. Specifically, in Patent Document 1, a male fastener is provided on the back surface of an inner panel, which is an absorbent article, and the inner panel is fixed by the male fastener in a state where the inner panel is covered with a paper diaper. Moreover, in the said patent document 2, it has an adhesion part in the flap edge part which the absorber does not exist in the auxiliary pad used as an absorbent article, and the auxiliary pad is fixed to the paper diaper by this adhesion part. However, none of the fasteners or adhesive parts were used for other purposes.

  Then, the main subject of this invention is providing the absorbent article which is excellent in the prevention of the pressure ulcer by the urine contamination of the buttocks made into the body back side.

In the absorbent article according to claim 1, an absorbent body composed of a fiber assembly formed at least so as to extend between a crotch portion applied to the crotch and a ventral portion extending to the front side thereof is a transparent material that allows liquid to permeate. In an absorbent article that is interposed between a liquid top sheet and a liquid-impermeable back sheet that does not allow liquid to permeate, and an exterior sheet made of a nonwoven fabric is laminated on the other surface side of the liquid-impermeable back sheet,
In the portion along the crotch portion of the absorbent body, a pair of slit portions that are respectively cut are extended along the direction in which the crotch portion extends linearly,
A temporary fixing portion that can be joined to other portions of the exterior sheet is provided on the outer portion of the exterior sheet with respect to the pair of slit portions.

The operation of the absorbent article according to claim 1 will be described below.
According to the absorbent article of the present claim, between the liquid-permeable top sheet and the liquid-impermeable back sheet, the crotch part applied to the crotch and the ventral part extending to the front side thereof are spanned. An absorbent body made of the formed fiber assembly is interposed. Moreover, the exterior sheet | seat which consists of a nonwoven fabric is laminated | stacked on the other surface side of this liquid-impermeable back sheet.

  On the other hand, a pair of slit portions that are cut into the absorber along the crotch portion respectively extend along the direction in which the crotch portion extends linearly, and the exterior sheet for the pair of slit portions A temporary fixing portion is provided on the outer portion of the. And when an absorber is each bent by these pair of slit parts, a temporary fix | stop part can join now with the other part of an exterior sheet | seat.

  That is, as a result of providing a pair of slit portions on the absorbent body and providing a temporary fixing portion on the outer portion of the exterior sheet rather than the pair of slit portions as the exterior sheet is laminated on the liquid-impermeable back sheet. When the absorbent article is applied to the crotch of the body, the absorbent article includes the absorbent body in the crotch part by bending the absorbent body with a pair of slit parts and temporarily fastening the outer parts of the exterior sheet with the temporary fastening parts. This part can always be kept in a mountain fold shape. Therefore, as the result that the absorbent article can always be closely adhered to the body's urination opening portion while maintaining the mountain fold shape of the absorbent article, local absorption is promoted in the ventral part and the buttock is not wetted with urine. As a result, skin troubles such as pressure ulcers on the buttocks can be reduced.

The operation of the absorbent article according to claim 2 will be described below.
The absorbent article which concerns on this claim has the same effect as claim 1. However, in the present claim, the temporary fixing portions are disposed on different sides of the outer sheet when the absorbent body is bent by the pair of slit portions on different sides of the pair of slit portions. In this form, a plurality of units are provided.

  That is, according to the present claim, the presence of the plurality of temporary fixing portions not only allows the portion of the absorbent article including the absorbent body to be more reliably folded in the crotch portion, but also, for example, a paper diaper When puncturing, the non-woven fabric affixed to the inner surface of the paper diaper is joined with multiple temporary fixing parts that are widely arranged on different parts of the outer sheet, so that the absorbent article can be reliably displaced with respect to the paper diaper. Will be able to prevent.

The operation of the absorbent article according to claim 3 will be described below.
The absorbent article which concerns on this claim has the same effect as claim 1. However, in the present claim, a configuration in which a diffusion preventing portion that forms a cut from one side edge of the absorber to the other side edge is formed in the rear portion of the absorber rather than the pair of slit portions. have.
In other words, according to the present invention, the diffusion prevention unit can not only always adhere the absorbent article to the body urination port in a planar manner, but also more reliably prevent urine from going to the buttocks side. Can be stopped by. Accordingly, the absorption of local urine in the abdominal part can be promoted and the buttock can be reliably prevented from getting wet with urine, so that skin troubles such as pressure ulcers on the buttock can be further reduced.

The operation of the absorbent article according to claim 4 will be described below.
The absorbent article which concerns on this claim has the same effect as claim 1. However, in this claim, it has the structure that the temporary fixing part is a mechanical tape. In other words, according to the present invention, when the temporary fixing portion is a mechanical tape, when the outer portions of the exterior sheet with respect to the pair of slit portions are temporarily fixed by joining with the temporary fixing portion, the absorbent body is in the crotch portion. It becomes possible to keep the folded shape more reliably.

  As described above, according to the present invention, there are advantages such as an absorbent article excellent in prevention of pressure ulcer due to urine contamination of the buttocks on the back side of the body.

  Hereinafter, the first embodiment of the absorbent article according to the present invention will be described with reference to an example of an absorbent pad, but the present invention can also be applied to various paper diapers such as a stationary type or a pants type. Is.

  FIGS. 1-6 has shown the absorption pad of 1st Embodiment used as the specific example of the absorbent article which concerns on this invention. This absorbent pad is assumed to be used alone or laid on the inner surface of a paper diaper, and extends between the crotch portion M applied to the crotch in the front-rear direction intermediate portion and both the front and rear sides thereof. It has a ventral part F and a dorsal part B.

  The dimensions of each part can be determined as appropriate, the total length (length in the front-rear direction) L1 can be about 490 to 630 mm, and the total width can be about 280 to 320 mm. In this case, the length in the front-rear direction of the crotch M is 150. About 190mm, width is about 280-320mm, length in the front-rear direction of the ventral part F3 is about 110-150mm, width is about 150-320mm, and length in the front-rear direction of the back part B is about 110-150mm, width Can be about 110 to 320 mm. In particular, as shown in the figure, the width of the ventral part F is wider than the width of the dorsal part B (for example, about 50 to 100 mm), the ventral side of the crotch M is the same width as the ventral part F, and the dorsal side is the back. It is preferable that the width of the crotch portion M is changed in the middle portion in the front-rear direction so as to have the same width as the side portion B.

  This absorption pad is a position between the inner surface of the liquid-impervious backsheet 2 that does not allow liquid permeation and the liquid-permeable top sheet 1 that allows liquid to permeate, and is a portion that extends from the crotch portion M to the ventral portion F. Further, it has a basic structure in which an absorbent body 3 made of a fiber assembly is interposed. And the exterior sheet 12 which consists of a nonwoven fabric is laminated | stacked on the outer surface side used as the other surface side of this liquid-impermeable back sheet 2. FIG.

As the absorbent body 3, a laminate of pulp fibers, an aggregate of filaments such as cellulose acetate, or a non-woven fabric can be used, and an absorbent polymer mixed or fixed as necessary can be used. If necessary, the absorbent body 3 can be wrapped with crepe paper (not shown). Moreover, the shape of the absorber 3 can be made into an appropriate shape such as a strip shape in which the front side portion is wider than the rear side portion, a rectangular shape, or a trapezoidal shape as shown in the figure.
The fiber basis weight and the basis weight of the absorbent polymer in the absorbent body 3 can be determined as appropriate, but the fiber basis weight is preferably about 150 to 400 g / m ^2, and the basis weight of the absorbent polymer is about 150 to 420 g / m ^2. Is preferable.

  On the back side of the absorbent body 3, the liquid-impermeable back sheet 2 is provided so as to protrude slightly from the peripheral edge of the absorbent body 3. As the liquid-impermeable back sheet 2, a sheet having moisture permeability can be used without impairing the water barrier from the viewpoint of stuffiness prevention in addition to a polyethylene film or the like. This water-impervious / breathable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. Can be used.

  Further, the outer surface side of the liquid-impermeable back sheet 2 is covered with the exterior sheet 12 made of a non-woven fabric as described above, and the exterior sheet 12 is outside the periphery of the back sheet 2 with a predetermined protrusion width. I'm sticking out. Various nonwoven fabrics can be used as the exterior sheet 12. As the material fiber constituting the nonwoven fabric, synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and amide, recycled fibers such as rayon and cupra, and natural fibers such as cotton can be used.

  The surface side of the absorber 3 is covered with a liquid-permeable top sheet 1. Although the absorber 3 partially protrudes from the side edge of the top sheet 1 in the illustrated form, the width of the top sheet 1 can be widened so that the side edge of the absorber 3 does not protrude. As the top sheet 1, a perforated or non-porous nonwoven fabric or a perforated plastic sheet is used. As the material fiber constituting the nonwoven fabric, synthetic fibers such as polyethylene or polypropylene, synthetic fibers such as polyester and amide, recycled fibers such as rayon and cupra, and natural fibers such as cotton can be used.

  At both ends in the front-rear direction of the absorbent pad, the exterior sheet 12 and the liquid-permeable top sheet 1 are respectively attached to the front and rear ends of the absorbent body 3 so as to extend to the front and rear sides. Is formed. On both sides of the absorbent pad, the exterior sheet 12 extends outward from the side edge of the absorbent body 3, and the width direction of the barrier sheet 4 is formed on the inner surface of the portion from the extended part to the side part of the top sheet 1. The outer portion 4x is affixed over the entire front-rear direction and constitutes a side flap portion SF where the absorber 3 does not exist. These pasted portions are shown as dotted patterns in FIG. 3, and can be formed by hot melt adhesive, heat sealing, or ultrasonic sealing. When the exterior sheet 12 is not provided, the liquid-impermeable back sheet 2 can be extended to the side flap portion SF instead of the exterior sheet 12 to form the outer surface side of the side flap portion SF.

As the material for the barrier sheet 4, a plastic sheet or a melt blown nonwoven fabric can be used. However, in terms of touch to the skin, a nonwoven fabric that is water-repellent treated with silicon or the like is preferably used.
A portion 4c on the center side in the width direction of the barrier seat 4 extends to the top sheet 1, and an elongated elastic member 4G is stretched along the front-rear direction at the end on the center side in the width direction. It is fixed with a melt adhesive or the like. As this elongated elastic member 4G, styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicon, polyester, etc., which are formed in a thread shape, a string shape, a belt shape, etc. Ordinarily used materials can be used.

  The barrier sheets 4 and 4 are fixed by being bonded to the inner surface of the article (in the illustrated form, the top sheet 1 surface and the exterior sheet 12 inner surface) over the entire front and rear direction, and the width direction center side. 4c is bonded and fixed to the inner surface of the article (top sheet 1 surface in the illustrated embodiment) at both ends in the front-rear direction, and is fixed to the inner surface of the article (top sheet 1 surface in the illustrated embodiment) between both ends in the front-rear direction. It has not been. As shown in FIG. 3, the non-fixed portion is a portion that becomes a barrier portion that can stand up with respect to the inner surface of the article (the surface of the top sheet 1 in the illustrated embodiment). It is located at the boundary between the outer fixed portion 4x and the inner portion 4c.

  As shown also in FIG. 6, the left and right side portions of the central portion in the width direction of the crotch portion M in the absorbent body 3 are a pair of slit portions that are cut from the boundary with the abdominal side portion F to the rear side of the article. The first easy-bending portion 3y extends linearly along the direction in which the crotch portion M extends. Further, from the front end portion of the left first easy-bend portion 3y in the absorbent body 3 to the left edge in the width direction and from the front end portion of the right first easy-fold portion 3y in the absorber 3 to the right edge in the width direction Each of the second easy-bend portions 3x extends linearly.

  It is preferable that the left and right first easy-bend portions 3y have a width direction interval D1 of 60 to 150 mm and a front-rear direction length L2 of 50 to 100 mm. If the width direction interval D1 is too narrow, it is difficult to maintain the bulge of the crotch portion M, and if it is too wide, the bulge in the crotch portion M becomes too large, resulting in a feeling of wearing. The first easy-bend portion 3y preferably has an angle θ1 with respect to the front-rear direction within a range of ± 30 degrees, more preferably within a range of ± 10 degrees, and particularly 0 degrees as shown in the figure. Is preferred. Moreover, the 1st easy bending part 3y can also be made into the curved shape where the front-back direction intermediate | middle part bulges in the width direction center side other than linear form like the example of illustration, for example along a leg periphery. Moreover, it is also preferable that the leading edge 4f of the barrier sheet 4 is positioned on or near the first easy-bend portion 3x in the unfolded state shown in FIG.

  The second easy-bending portion 3x is provided in the range where the angle θ2 with respect to the width direction is −60 degrees to +60 degrees (the state along the width direction is 0 degrees as shown). This angle range is preferably ± 45 degrees, more preferably 0 to +60 degrees (+ is an oblique front side), and particularly preferably 0 to +45 degrees. Further, the second easy-bending portion 3x has a linear shape as in the illustrated example, and also has a curved shape in which the middle portion in the front-rear direction bulges to the front side of the pad and to the center side in the width direction along the flange portion, for example. You can also. Here, the easily bent portions 3y and 3x of the present invention can be formed by slits that are more easily bent, and the width is preferably about 5 to 20 mm.

  As shown in FIG. 2 and FIG. 4, the back surfaces of the mechanical tapes 14 a and 14 b which are temporary fixing portions formed in a quadrangular shape are attached to the outer portion of the exterior sheet 12 with respect to the pair of first easy-bend portions 3 y. By being pasted by 15a, the two mechanical tapes 14a and 14b having hooks 15b on the respective surface sides are fixed to the outer portions of the exterior sheet 12, respectively. Specifically, as shown in FIG. 2, the absorbent body 3 is folded into a mountain fold at a pair of first easy-to-fold portions 3y on different sides with the pair of first easy-to-bend portions 3y sandwiched therebetween. In this case, two mechanical tapes 14a and 14b each having a male shape are provided in such a manner that they are arranged at different positions on the exterior sheet 12, respectively.

  In other words, in the present embodiment, one mechanical tape 14a is disposed at the position on the upper left side in FIG. 2 that is the outer portion of the pair of first easy-bend portions 3y, and the other mechanical tape 14b is a pair of mechanical tapes 14b. It is arrange | positioned in the position near the lower right side of FIG. 2 made into the outer part of the 1st easy bending part 3y. When the absorbent body 3 is bent by the pair of first easy-bending portions 3y, the mechanical tape 14a closer to the upper left side is the other outer portion of the exterior sheet 12 with respect to the pair of first easy-folding portions 3y. Is temporarily joined to the upper right side portion of the exterior sheet 12. Similarly, when the absorbent body 3 is bent, the mechanical tape 14b near the lower right side is temporarily placed on the lower left side portion of the exterior sheet 12 that is the other outer portion of the exterior sheet 12 with respect to the pair of first easy-bend portions 3y. Be joined.

  At this time, the male mechanical tapes 14a and 14b are temporarily joined to each other without any problem while having a necessary adhesive force to the exterior sheet 12 which is a non-woven fabric, and can be easily removed when necessary. For this reason, as shown in FIG. 5, when at least the crotch portion M of the absorbent pad is folded in a mountain and applied to the body, for example, when pants-type paper diapers are to be worn, between the mechanical tapes 14a, 14b and the outer sheet 12. Is removed, and the two mechanical tapes 14a and 14b are joined to the nonwoven fabric stuck on the inner surface side of the paper diaper, respectively, so that the absorption pad can be prevented from shifting with respect to the paper diaper.

  In a more preferable form, as shown in the drawing, a slit is continuously formed from the side edge on the one side in the width direction of the absorbent body 3 to the side edge on the other side behind the first easily bent portion 3y in the crotch portion M. A diffusion preventing portion 3z formed of a compression processing portion by slit or embossing is formed in a V shape. When the diffusion preventing unit 3z is provided as described above, the osmotic diffusion of urine absorbed at the front side is blocked or blocked by the diffusion preventing unit 3z. Therefore, since the diffusion of urine to the back side is prevented, the pressure ulcer prevention effect is further enhanced. The width of the diffusion preventing part 3z is preferably about 5 to 20 mm. Further, as the diffusion preventing unit 3z, a slit is preferable because it has a higher effect of blocking urine diffusion.

The diffusion preventing portion 3z is preferably provided within a range of the crotch portion M in a range from the rear end of the first easily bent portion 3y to a position of 10 mm on the front side and a position of 30 mm on the rear side. Further, the shape of the diffusion preventing portion 3z can be determined as appropriate, but a V-shaped shape in which the intermediate portion in the width direction bulges forward is preferable as shown in FIG.
As such a bulging shape, a chevron that is bent at the center in the width direction as shown in the drawing is preferable to a curved shape, and inflection points are used to make the shape gradually along the width direction as shown in the drawing. It is preferable to provide it. When the diffusion preventing part 3z has such a bulging shape, the urine that permeates and diffuses toward the rear side changes its direction obliquely along the diffusion preventing part 3z, making it difficult to exceed the diffusion preventing part 3z. .

Furthermore, in order to prevent the spread of urine to the back side and further enhance the pressure ulcer prevention effect, it is preferable that the absorber 3 has a structure that does not extend to the back side portion B as shown in FIG. In the absorbent pad thus configured, the first easy-bend portion 3y is mountain-folded when viewed from the body side (inner surface side), and the second easy-bend portion 3x is valley-folded when viewed from the body side (inner surface side). As a result, the central part in the width direction of the crotch part M bulges to the body side with respect to both the left and right sides, and the bulging part is elastically adhered to the crotch part while being supported on both the left and right sides. It can withstand the weight and maintain close contact. And the ventral part F stands on the body side with respect to the crotch part M in the part located in front of the second easy-bend part 3x, and fits well to the lower abdomen. Since it is difficult to apply unnecessary force, a situation in which a gap is generated in the crotch portion due to the displacement of the ventral portion F is also unlikely to occur.
Further, in the illustrated form, the rear end of the absorbent body 3 is located at the boundary between the crotch M and the back part B, so that the back part B also stands on the body side with respect to the crotch M, and the body buttock It fits well.

Next, the operation of the absorption pad according to the present embodiment configured as described above will be described.
According to the absorbent pad of the present embodiment, between the liquid-permeable top sheet 1 and the liquid-impervious back sheet 2, the crotch part M applied to the crotch of the body and the ventral part extending to the front side thereof An absorbent body 3 made of a fiber assembly formed so as to extend over F is interposed. An exterior sheet 12 made of a nonwoven fabric is laminated on the other surface side of the liquid-impermeable back sheet 2.

  On the other hand, a pair of first easy-to-bend portions 3y that are respectively cut into the both sides of the crotch portion M in the absorbent body 3 are linearly extended along the direction in which the crotch portion M extends. Mechanical tapes 14a and 14b, which are two temporary fixing portions, are provided on the outer portion of the exterior sheet 12 with respect to the pair of first easily bent portions 3y. The mechanical tapes 14a and 14b can be joined to the other portions of the exterior sheet 12 when the absorber 3 is bent by the pair of first easy-bending portions 3y.

  Specifically, the outer sheets 12 are different from each other when the absorbent body 3 is bent by the pair of first easy-bending portions 3y on the different sides between the pair of first easy-bending portions 3y. These two mechanical tapes 14a and 14b are provided on the exterior sheet 12 in such a manner that they are respectively disposed in the portions.

  In other words, the absorbent body 3 is provided with a pair of first easily bent portions 3y, and the exterior sheet is more than the pair of first easily bent portions 3y as the exterior sheet 12 is laminated on the liquid-impermeable back sheet 2. As a result of providing the mechanical tapes 14a and 14b on the outer portion of the body 12, when the absorbent pad is applied between the crotch of the body, the absorbent body 3 is folded by the pair of first easy-folding portions 3y to By temporarily fastening the parts with the mechanical tapes 14a and 14b, the part of the absorbent pad including the absorbent body 3 can always be kept in a mountain fold shape in the crotch part M. Accordingly, as the absorption pad can be kept in the mountain fold shape, the absorption pad can always be closely adhered to the body's urination opening so as to promote local absorption at the ventral portion F so as not to wet the buttocks with urine. With this, skin troubles such as pressure ulcers on the buttocks can be reduced.

  According to the present embodiment, the presence of the two mechanical tapes 14a and 14b not only allows the crotch portion M to more reliably maintain the portion of the absorbent pad including the absorbent body 3 in the folded shape. When puncturing a paper diaper, the non-woven fabric stuck on the inner surface side of the paper diaper is bonded to the paper diaper by joining with two mechanical tapes 14a and 14b widely arranged in different parts of the exterior sheet 12. It is possible to reliably prevent the shift of the property article.

  In addition, since the temporary fixing portions are the mechanical tapes 14a and 14b, when the outer portions of the exterior sheet 12 with respect to the pair of first easily bent portions 3y are temporarily bonded by mechanical tapes 14a and 14b, the absorber 3 can be kept in the folded shape in the crotch portion M more reliably.

  On the other hand, in the present embodiment, diffusion that is a cut from one side edge of the absorbent body 3 to the other side edge in the rear side portion of the absorbent body 3 rather than the pair of first easily bent portions 3y. Since the prevention part 3z is formed, not only can the absorption pad be in close contact with the urination port of the body at all times, but also the diffusion of the urine to the buttocks side more reliably due to the presence of the diffusion prevention part 3z. It can be blocked by the prevention unit 3z. As a result, local urine absorption at the ventral portion F can be promoted and the buttock can be reliably prevented from getting wet with urine, so that skin troubles such as pressure ulcers on the buttock can be further reduced. .

Next, a second embodiment of an absorbent article according to the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the member same as the member demonstrated in 1st Embodiment, and the duplicate description is abbreviate | omitted.
In the first embodiment, the mechanical tape 14a, 14b is attached to the exterior sheet 12 with an adhesive or the like, and the mechanical tape 14a, 14b is joined to the other part of the exterior sheet 12 as a mechanical tape. 14a and 14b are temporarily fixed to the portion of the exterior sheet 12 joined, but in the present embodiment, as shown in FIG. The mechanical tape 14 and the female mechanical tape 16 were used, and these were each attached to the exterior sheet 12 with an adhesive or the like.

  That is, in the present embodiment, the male mechanical tape 14 is disposed at a position on the left side in FIG. 7 which is the outer portion of the pair of first easy-bend portions 3y, and the female mechanical tape 16 is It arrange | positions in the position near the right side of FIG. 7 used as the outer part of a pair of 1st easy bending part 3y.

  For this reason, the male mechanical tape 14 and the female mechanical tape 16 are disposed at the same position with the pair of first easy-bending portions 3y interposed therebetween, and the pair of first tapes. When the absorbent body 3 is bent at the easy bending portion 3y, the male mechanical tape 14 is temporarily joined to the female mechanical tape 16. As a result, as in the first embodiment, as the absorbent pad is kept in the mountain fold shape, the buttock can be prevented from getting wet with urine, and skin troubles such as a pressure ulcer on the buttock can be reduced.

  In the first embodiment, the temporary fixing portion is two male mechanical tapes 14a and 14b. In the second embodiment, the temporary fixing portion is a male mechanical tape 14 and a female mechanical tape. Although the tape 16 is used, the temporary fixing portions are not limited to these mechanical tapes, and the number of temporary fixing portions is not limited to the number of the above-described embodiments, and may be further increased.
