Description

  The present invention relates to an absorbent pad for men.

  2. Description of the Related Art Conventionally, a male absorbent pad including a pad body having a longitudinal direction and a transverse direction intersecting the same, a skin facing surface and a non-skin facing surface on the opposite side, and having a liquid-absorbing core is known. For example, Patent Literature 1 discloses an absorbent pad including a pad body having a first end region and a second end region that are spaced apart from each other in the vertical direction, and an intermediate region located between the first and second end regions. Has been.

  The absorbent pad includes a bending guide groove having a first groove that intersects with the longitudinal axis and extends obliquely and a second axis that intersects with the longitudinal axis and extends in a direction intersecting the first groove. .

Japanese Patent No. 5433815

  In the absorbent pad disclosed in Patent Document 1, the absorbent pad is deformed along the first and second grooves extending obliquely across the vertical axis. Therefore, since this absorbent pad is deformed into a certain cup shape, even when the wearer's posture changes, the cup shape is maintained, and the wearer feels uncomfortable when wearing and during wearing. There was a possibility that it would be recognized from the outside that the absorbent pad was worn during wearing. Moreover, in the state which shifted clothes, such as underwear, the subject that a wrinkle is easy to be formed in underwear with the absorption pad occurred. Furthermore, since the absorbent pad for men is not attached to the crotch portion of the underwear like that for women, it is attached to the front side of the body, so that there is a problem that positioning is not easy.

  The present invention is an improvement of a conventional absorbent pad, and provides an absorbent pad that is not easily wrinkled on clothing, easy to align, deforms according to the posture of the wearer, and is inconspicuous from the outside. It is an issue.

  The present invention is based on a male absorbent pad including a pad body having a longitudinal direction and a transverse direction intersecting the same, a skin facing surface and a non-skin facing surface opposite thereto, and having a liquid-absorbing core. .

The absorbent pad according to the present invention is characterized in that the pad main body has a first end region and a first end region covered with a pair of cover sheets facing each other in the longitudinal direction on the skin facing surface side. An intermediate region located between the region and the second end region, both side regions covered with a pair of barrier cuff sheets facing each other in the lateral direction, and the cover sheet and the barrier cuff sheet in the intermediate region A plurality of deformation guide portions that are recessed from the skin facing surface side to the non-skin facing surface side only in the exposed region of the pad body. An arranged deformation induction area is formed, and the vertical dimension of the deformation induction area is 10.0 to 60.0% of the vertical dimension of the pad body, and the horizontal dimension of the deformation induction area. The dimension of the direction is the above The first deformation guiding portion arbitrarily selected from the plurality of deformation guiding portions is a size of 15.0 to 45.0% of the horizontal dimension of the head body. Are arranged side by side in the vertical direction with respect to the third deformation guiding part, arranged side by side in the lateral direction with respect to the fourth and fifth deformation guiding parts, and with respect to the sixth and seventh deformation guiding parts. The deformation guiding portions are arranged side by side in an inclination direction intersecting the vertical direction and the horizontal direction, and the deformation guiding portion has a shape that can be deformed in a plurality of different directions .

The pad body of the absorbent pad according to claim 2 , wherein the pad body is a liquid-permeable body-side liner located on the skin-facing surface side and a liquid-impermeable back sheet located on the non-skin-facing surface side. If, before Symbol barrier cuff sheet has the longitudinally contractible mounted further a cuff elastic member, and said body-side liner, said backsheet, said barrier cuff sheet outside the pad body Joined by a seal line along the periphery, and a non-joined portion that is not joined by the seal line is located in a region where at least one end of the cuff elastic body is present. According to the above absorbent pad, since the rigidity is increased at both ends of the cuff elastic body, in this part, it is difficult to form a curved shape along the body. The entire pad can be deformed into a curved shape along the body, and even when worn on clothes such as briefs that are in close contact with the body, unnatural deformation and wrinkles are hardly noticeable from the outside.

The pad body of the absorbent pad according to claim 3 has a dimension in the thickness direction of 3.0 mm or less. According to the above absorbent pad, since it is relatively thin, it becomes more compact when bent. Moreover, it is not conspicuous from the outside even while wearing.

The said deformation | transformation induction | guidance | derivation part of the absorption pad which concerns on Claim 4 is a cross shape which the 1st line extended in the said vertical direction and the 2nd line extended in the said horizontal direction cross | intersect. According to the absorbent pad, force is concentrated and applied to the peripheral part between the deformation guiding portions in each of the vertical direction and the horizontal direction, whereby the deformation induction area is easily deformed along the vertical direction and the horizontal direction. To do.

In the absorption pad according to a fifth aspect , in the deformation induction region , the number of the deformation induction portions per unit area is sparse outside the vertical direction. According to the above-mentioned absorption pad, the absorption pad is gently curved without suddenly bending at the boundary between the existence area where the deformation induction part exists and the non-existence area where the deformation induction part does not exist.

The said pad main body of the absorption pad which concerns on Claim 6 further has the adhesive fastening part located in the said non-skin opposing surface side, and the said fastening part is an outer side of the said vertical direction rather than the said deformation | transformation induction area. Extend to. According to the above-mentioned absorption pad, since the fastening part sticks to the clothes on the outer side in the vertical direction of the deformation induction area, it is integrated with the clothes up to the outer side of the deformation induction part. Therefore, it is possible to suppress the absorption pad from being suddenly bent at the boundary between the existence area where the deformation induction part exists and the non-existence area where the deformation induction part does not exist.

  According to the absorbent pad according to the present invention, only in the middle region, the plurality of deformation guide portions are arranged at intervals in the vertical direction and the horizontal direction, so when wearing the absorbent pad and during wearing The intermediate region is deformed according to the posture of the wearer. For this reason, there is no fear that the wearer may feel uncomfortable when wearing and during wearing, and there is no possibility that the outside will know that the absorbent pad is worn during wearing. Further, even when the clothes such as underwear are shifted, the absorbent pad is deformed by the deformation guiding portion, so that it is difficult to form wrinkles on the clothes. In addition, since the deformation guiding portion is disposed only in the intermediate region, the deformation guiding portion serves as a mark when worn and positioning is easy.

The second end edge 10 b is more gently curved than the first end edge 10 a, has a larger dimension in the lateral direction X, and the second end area 12 is wider than the first end area 11. The absorbent pad 10 has a substantially triangular shape in a plan view in which the distance between the side edges 10c and 10d gradually increases from the first edge 10a side to the second edge 10b side. In addition to the planar view shape, the absorbent pad 10 may have various known planar shapes such as a circular shape and a rectangular shape as long as the effects of the present invention described later can be obtained. Referring to FIG. 6, the first end region 11 of the absorbent pad 10 is against the wearer's crotch (below the scrotum 49), the intermediate region 13 is against the penis 48, and the second end region 12 is against the lower abdomen 47.

Side flaps extending in the vertical direction Y outside the lateral direction X of both side edges 23c of the liquid core 23, and end flaps extending in the horizontal direction X outside the vertical direction Y of both end edges 23a, 23b of the liquid absorbent core 23 Have

<Pad body>
As shown in FIG. 2, the pad main body 20 includes a body side liner 21 positioned on the skin facing surface side, a back sheet 22 positioned on the non-skin facing surface side, and the body side liner 21 and the back sheet 22. And a liquid-absorbent core 23 positioned therein. Further, as an option, a cushion sheet 24 is disposed between the body side liner 21 and the liquid absorbent core 23.

  The body side liner 21 and the cushion sheet 24 are formed from a fiber nonwoven fabric having liquid permeability. The back sheet 22 is formed from a hardly liquid-permeable or liquid-impervious fiber nonwoven fabric, a breathable plastic film, or a laminate sheet thereof.

  The absorbent core 23 is shaped substantially the same as the pad body 20 and is made of absorbent material formed from a mixture comprising wood fluff pulp, absorbent polymer particles (SAP), and optionally thermoplastic fibers. It includes a core material and a liquid diffusive sheet such as tissue paper covering the core material. As the liquid diffusive sheet, a sheet coated with a water-soluble antibacterial agent soluble in water can be used. When such a liquid diffusable sheet is used, an antibacterial effect can be obtained by contacting a body fluid such as urine with the liquid diffusible sheet, and if the antibacterial agent is colored, the body side liner 21 is colored. The formed liquid diffusion sheet is clearly visually recognized, and the portion where the deformation guiding portion 40 is formed looks darker than the portion where the deformation guiding portion 40 is not formed, and thus can be used as a mark for alignment. Examples of the antibacterial agent include cetylpyridinium chloride (CPC) and benzalkonium chloride.

  The dimension L1 in the vertical direction Y of the pad main body 20 is about 160 to 300 mm, and the dimension W1 in the horizontal direction X is about 120 to 300 mm. The thickness of the peripheral portion 46 that is out of the deformation guiding portion 40 shown in FIG. The dimension R1 in the direction Z is about 3.0 mm or less, and the dimension R2 in the thickness direction Z of the deformation guiding part 40 is about 0.3 mm or less. When the difference between the dimensions R1 and R2 is given, the cup shape with the deformation induction region 43 as the bottom and the peripheral portion 46 as the side wall becomes clear due to the difference in rigidity between the two.

  Referring to FIG. 3, on the back surface side of the absorbent pad 10, that is, on the non-skin facing surface side of the back sheet 22, a vertical length formed from a pressure-sensitive adhesive for attaching the absorbent pad 10 to clothing such as underwear.

Side fixing portions 32 located on both sides of the main body. The center fastening part 31 and the side fastening part 32 are covered with a separator 33 made of plastic or non-woven fabric.

<Deformation induction part>
Referring to FIGS. 2 and 7, in the pad main body 20, in the vertical direction Y, a plurality of deformation guiding portions 40 are arranged at intervals in the vertical direction Y and the horizontal direction X only in the intermediate region 13. . In other words, the pad main body 20 has a plurality of deformation guiding portions 40 arranged only in the central region 15 in the lateral direction X. A plurality of deformation guiding portions 40 define a deformation guiding area 43 in which the pad main body 20 is easily deformed. In this embodiment, the deformation guide area 43 is arranged at a location where the barrier cuff sheet 50 and the cover sheet 60 are not present, and the deformation guide portion 40 is not present where the barrier cuff sheet 50 and the cover sheet 60 are present. A region 44 is arranged. That is, the pad body 20 has a non-existing area 44 outside the deformation induction area 43 in the vertical direction Y and the horizontal direction X.

  In this embodiment, five deformation guide portions 40 are arranged at intervals in the horizontal direction X on the outermost side in the vertical direction Y of the deformation guide region 43, and four deformation guide portions 40 are arranged on the inner side thereof. Are arranged in the transverse direction X with an interval. Inside these, five deformation guide portions 40 and four deformation guide portions 40 are alternately arranged in the vertical direction Y in the horizontal direction. In addition, in the proximal portion 39 of the center O where the vertical center line P and the horizontal center line Q intersect, one deformation guiding portion 40a arbitrarily selected from the plurality of deformation guiding portions 40 includes two other deformation guiding portions. 40b and 40c are arranged side by side in the vertical direction Y, and are arranged side by side in the horizontal direction X with respect to the other two deformation induction parts 40d and 40e, and another two deformation induction parts 40f and 40g (40h, 40i) are arranged side by side in a direction inclined with respect to the vertical direction Y and the horizontal direction X (hereinafter simply referred to as “inclined direction”). The separation dimension of the deformation guide portions 40 arranged in the vertical direction Y is preferably about 5 to 50 mm, and the separation size of the deformation guide portions 40 arranged in the horizontal direction X is preferably about 5 to 30 mm. The distance between the guide portions 40 is preferably about 7 to 60 mm. The ratio of the dimension L2 in the longitudinal direction Y of the deformation induction area 43 to the dimension L1 in the longitudinal direction Y of the absorbent pad 10 is about 20.0 to 60.0%, and the dimension in the lateral direction X of the absorbent pad 10 The ratio of the dimension W2 in the lateral direction X of the deformation induction area 43 to W1 is about 15.0 to 45.0%.

  As shown in FIG. 8, each deformation guiding portion 40 has a cross shape in which a first line 41 extending in the vertical direction Y and a second line 42 extending in the horizontal direction X intersect. Further, as shown in FIG. 5, the deformation guiding area 43 has a dimension L3 in the longitudinal direction Y of the center fastening portion 31 larger than a dimension L2 in the longitudinal direction Y.

  The deformation guide portion 40 is formed by, for example, pin embossing (or pin debossing) processing. More specifically, the body side liner 21 is pressed by pressing from the body side liner 21 toward the back sheet 22 with a boss (pin). The back sheet 22, the liquid absorbent core 23, and the cushion sheet 24 are formed. Therefore, each deformation guide part 40 has a small dimension R2 in the thickness direction Z and high rigidity compared to the dimension R1 in the thickness direction Z of the peripheral portion 46 that is removed from the deformation guide part 40.

<Barrier cuff sheet>
As shown in FIGS. 1 and 2, the barrier cuff sheet 50 has a shape that extends in the longitudinal direction Y and gradually tapers from the second edge 10b toward the first edge 10a. It can be formed from a liquid-impervious fiber nonwoven fabric. The barrier cuff sheet 50 is fixed to the pad main body 20 and extends along the side edges 10c and 10d, and both fixed end portions fixed to the pad main body 20 in the first and second end regions 11 and 12. 58 and a sleeve-like free edge 52 (distal edge) formed by folding the inner edges 10c, 10d of the barrier cuff sheet 50 inwardly, extending in the longitudinal direction Y between the fixed ends 58. Have. The proximal edge portion 57 is a part of the seal portion 18, and the fixed both end portions 58 excluding the both end portions 53 a of the cuff elastic element 53 are also a part of the seal portion 18. In other words, the barrier cuff sheet 50 is fixed to the pad main body 20 through the seal portion 18 except for the free edge portion 52 and both end portions 53 a of the cuff elastic element 53.

  A string-like or strand-like cuff elastic element 53 extending in the longitudinal direction Y is fixed to the free edge portion 52 of the barrier cuff sheet 50 so as to be contracted in an expanded state. A contraction region (side elastic portion) 54 that can be expanded and contracted is formed. Two cuff elastic elements 53 are arranged on one side in the lateral direction X at intervals of 3.0 to 15.0 mm. The free edge 52 is separated from the skin-facing surface of the body side liner 21 by the contracting action of the cuff elastic element 53 in the wearing state, and a pair of barrier cuffs (three-dimensional cuffs) for preventing side leakage of excrement such as urine. It is formed. The cuff elastic element 53 is, for example, an elastic material having a thickness (diameter) of about 310 to 1240 dtex and fixed in a state of being stretched about 1.2 to 2.0 times from a contracted or relaxed state. Can be used.

  The barrier cuff sheet 50 has a contracted region 54 in which the cuff elastic element 53 is disposed in an expanded state, and a non-contracted region 55 in which the cuff elastic element 53 is disposed in a substantially inelastic state (FIG. 2). FIG. 9 and FIG. 10). The barrier cuff sheet 50 overlaps a part of the first and second cover sheets 61 and 62 and is fixed to the cover sheet 60 at the overlapped part. When the absorbent pad 10 is worn, the barrier cuff substantially rises as the contraction area 54 of the free edge 52 contracts. Here, “substantially inelastic” with respect to the non-shrinkable region 55 means that the cuff elastic element 53 is present in the region but does not exhibit any contractility, and a state that slightly develops contractility. Including.

  As shown in FIGS. 9 and 10, the both end portions 53 a of the cuff elastic element 53 are located at the non-joined portions 53 b that are not joined by the seal portion 18 in the region where the both end portions 53 a of the cuff elastic element 53 exist. The dimension W3 of the non-joining part 53b in the horizontal direction X is 1.0 to 10.0 mm.

<Cover sheet>
The first and second cover sheets 62 are formed from an inelastic sheet material, and are formed from, for example, a hardly liquid-permeable or liquid-impervious fiber nonwoven fabric, a breathable plastic film, or a laminate sheet thereof. Can do. The first and second cover sheets 62 have inner edge portions 61 a and 62 a extending in the lateral direction X between the inner edge portions 50 a of the barrier cuff sheet 50.

  Each of the first and second cover sheets 61 and 62 is fixed to the body side liner 21 at both ends in the vertical direction Y and in the center in the horizontal direction X as shown in FIGS. 9 and 10. Parts 68 and 69, and non-fixed parts 68a and 69a not fixed to the body side liner 21 located inside the central fixed parts 68 and 69 in the vertical direction Y. The non-fixed portions 68a and 69a overlap the liquid absorbent core 23 in plan view.

  Referring to FIG. 11, in a state where the absorbent pad 10 is placed on a flat floor, desk, or the like, the contraction area 54 is contracted to extend straight in the longitudinal direction Y, and the barrier cuff sheet 50 stands up to raise the first and second. The non-fixed portions 68 a and 69 a of the cover sheets 61 and 62 are separated from the body side liner 21, and the first and second cover sheets 61 and 62 and the body side liner 21 are provided with a first for storing excrement. A space portion 72 and a second space portion 73 are formed. In this state, in the vertical direction Y, the pad main body 20 is formed by a flat plate-shaped deformation induction area 43, a non-existing area 44 extending straight, and a deformation area 45 between the deformation induction area 43 and the non-existing area. The cup has a cup shape with the deformation induction area 43 as the bottom and the non-existence area 44 as the side. When the pad main body 20 takes such a form, the first space portion 72 and the second space portion 73 gradually increase in the thickness direction Z from the inner edge portions 61a and 62a toward the first and second end edges 10a and 10b. The dimensions are small.

  Referring to FIG. 2, the inner edge 50a of the barrier cuff sheet 50 and the inner edges 50a of the first and second cover sheets 61 and 62 define an insertion port 63 into which the wearer's penis 48 is inserted. .

  Referring to FIG. 6, when the wearer wears the absorbent pad 10, the penis 48 is inserted into the insertion opening 63. The scrotum 49 is located in contact with or away from the upper surface of the first end region 11. The pad main body 20 has a bottom formed from the deformation induction region 43 in the intermediate region 13 and the central region 15, and both the non-conductive regions 14 and the first and second end regions 11 and 12 when worn and in the worn state. An accommodation space S defined by the side portion formed from the existence area 44 and accommodating the penis 48 so as to wrap is formed.

  The excrement excreted during wearing is mainly absorbed and held in the peripheral portion 46 between the deformation induction portion 40 and the deformation induction portion 40 in the liquid absorbent core 23, and in the entire liquid absorbent core 23. Diffused. Further, when the wearer's posture changes, the rigidity of the deformation guiding part 40 is high and the rigidity of the peripheral portion 46 that is removed from the deformation guiding part 40 is low. The peripheral portion 46 between the deformation guiding portion 40 and the deformation guiding portion 40 is bent.

  According to this absorbent pad 10, the deformation guiding portion 40 is disposed in the intermediate region 13 and the central region 15 with an interval in the vertical direction Y and the horizontal direction X, so that the rigidity of the deformation guiding region 43 is a non-existing region. It is higher than the rigidity of 44, and it is easy for the deformation induction area 43 to maintain the surface shape (plate shape) before wearing. Therefore, it is easy to assign the intermediate area 13 and the central area 15 to clothes such as underwear. In addition, when the absorbent pad 10 is worn, the deformation guide portions 40 of the central region 13 and the central region 15 can be used as marks, so that the portion where the penis 48 abuts can be easily understood and aligned. Moreover, when wearing and after wearing, the intermediate | middle area | region 13 and the center area | region 15 deform | transform by the deformation | transformation induction | guidance | derivation part 40 according to a wearer's attitude | position. For this reason, even if a wearer's attitude | position changes, a strange feeling is not memorized. In addition, the pad main body 20 is easily deformed into a curved shape along the wearer's body by positioning the plurality of deformation guide portions 40 between the contraction regions 54. In addition, when excrement is excreted in the absorbent pad 10, the excrement is held by the peripheral portion 46 between the deformation induction part 40 and the deformation induction part 40 in the liquid absorbent core 23, and the thickness direction of the part Although the dimension of Z becomes large, since the deformation | transformation induction | guidance | derivation part 40 is arrange | positioned around the said part, it can suppress that the dimension of the thickness direction Z becomes larger than needed, and it is not conspicuous from the outside. Moreover, when the groove | channel part extended continuously like the absorption pad 10 disclosed by patent document 1 is formed in the pad main body 20, a big gather can be made into the pad main body 20, and there exists a possibility that excrement may leak by this big gather. However, in this absorbent pad 10, since the plurality of deformation guide portions 40 are arranged in the vertical direction Y and the horizontal direction X with a space between each other, the occurrence of a large gather is suppressed and excrement leaks. In addition to being able to prevent this, it is not conspicuous from the outside, and the formation of wrinkles on the clothes can be suppressed.

  Moreover, in this absorption pad 10, in the proximal part 39 of the center O, one deformation | transformation induction | guidance | derivation part 40a selected from the some deformation | transformation induction | guidance | derivation part 40 is each in the vertical direction Y, the horizontal direction X, and the inclination direction. These are arranged in another two deformation guiding portions 40. More specifically, when a force is applied to the pad main body 20 so that the end edges 10a and 10b approach each other by the deformation guide portions 40a, 40b, and 40c aligned in the vertical direction Y, the deformation induction aligned in the vertical direction Y. The pad body 20 is deformed and deformed at a peripheral portion 46 between the deformation guide portions 40 arranged in the longitudinal direction Y, such as a peripheral portion 46 between the portions 40a and 40b or a peripheral portion 46 between the deformation guide portions 40a and 40c. The guiding area 43 is easily deformed along the lateral direction X.

  When force is applied to the pad main body 20 by the deformation guiding portions 40a, 40d, 40e arranged in the lateral direction X so that the side edges 10c approach each other, the space between the deformation guiding portions 40a, 40d arranged in the horizontal direction X is between. The pad main body 20 is deformed at the peripheral portion 46 between the deformation guiding portions 40 arranged in the horizontal direction X, such as the peripheral portion 46 of the pad, or the peripheral portion 46 between the deformation guiding portions 40a and 40d, and the deformation guiding region 43 is in the vertical direction. It easily deforms along Y.

  Further, when force is applied to the pad body 20 from the tilt direction by the deformation guide portions 40a, 40f, 40g (40a, 40h, 40i) arranged in the tilt direction, the deformation guide portions 40a, 40f (40a) arranged in the tilt direction. , 40h) or the peripheral portion 46 between the deformation guide portions 40 arranged in the inclined direction, such as the peripheral portion 46 between the deformation guide portions 40a, 40g (40a, 40i), or the like. And the deformation | transformation induction | guidance | derivation area | region 43 deform | transforms easily along an inclination direction. Moreover, since the intermediate region 13 and the central region 15 are easily deformed in four different directions (vertical direction Y, horizontal direction X, and inclined directions perpendicular to each other), even if the posture of the wearer is changed, the change occurs. Accordingly, the intermediate region 13 and the central region 15 are easily deformed.

  Further, according to the absorbent pad 10, each deformation guiding portion 40 has a cross shape in which the first line 41 extending in the vertical direction Y and the second line 42 extending in the horizontal direction X intersect each other. In each of the direction Y and the horizontal direction X, force concentrates on the peripheral portion 46 between the deformation guide portions 40, whereby the deformation guide region 43 is easily deformed along the vertical direction Y and the horizontal direction X. . On the other hand, when the plurality of deformation guide portions are circular, the force is distributed and applied to the peripheral portions 46 between the deformation guide portions, so that the deformation guide portions do not deform so much as compared to the cross-shaped deformation guide portion 40.

  Furthermore, according to this absorbent pad 10, since the dimension in the thickness direction Z is 3.0 mm or less, it is relatively thin and more compact when bent. Moreover, it is not conspicuous from the outside even while wearing. Moreover, it integrates with the clothes and the absorbent pad 10 is deformed along with the deformation of the clothes.

  Moreover, according to this absorbent pad 10, since the deformation | transformation induction | guidance | derivation part 40 is arrange | positioned in the whole area of the intermediate | middle area | region 13 and the center area | region 15, the whole area | region of the intermediate | middle area 13 and the center area | region 15 which demarcates the accommodation space S is deformable. is there.

  Furthermore, according to the absorbent pad 10, the center fastening portion 31 extends outward in the longitudinal direction Y from the deformation induction region 43, and therefore the pad body 20 outside the deformation induction region 43 is bent integrally with the clothing. For this reason, the pad main body 20 does not suddenly bend at the boundary between the deformation induction region 43 where the deformation induction portion 40 exists and the non-existence region 44 where the deformation induction portion 40 does not exist, while the absorbent pad 10 is familiar with the underwear, Can be gently curved.

  Further, when the seal portions 18 are positioned at both ends of the cuff elastic element 53, the rigidity of both ends is increased. Therefore, in this portion, it is difficult to form a curved shape along the body. 10 makes it possible to reduce the rigidity by making both end portions 53a of the cuff elastic element 53 non-joining portions 53b, and to deform the entire pad into a curved shape along the body.

  According to this absorbent pad 10, the deformation guiding portion 40 is arranged so as to be sparse at the proximal portion 39 of the central deformation guiding portion 40, so that it is difficult to deform, while the central deformation guiding portion 40 Since the deformation inducing portion 40 is densely arranged at the distal portion, it is easily deformed. For this reason, the proximal part 39 centering on the deformation | transformation induction | guidance | derivation part 40s becomes a bottom part, and it deform | transforms easily in the cup shape by which the distal part 38 becomes a side part. Further, in the deformation guiding portions 40m and 40n arranged in the direction inclined with respect to the deformation guiding portion 40s, since the first and second lines 41 and 42 are arranged along the inclination direction, the deformation induction region 43 is inclined.
