前述立壁狀摺邊雖有提高往肌膚側之立起高度的優點，但存在容易倒向寬度方向，於倒塌狀態裝著之情形會發生體液外漏或產生不適感的缺點。
Although the aforementioned standing wall-shaped hem has the advantage of increasing the standing height toward the skin side, it has the disadvantage that it tends to fall in the width direction, and when it is mounted in a collapsed state, body fluid leakage or discomfort may occur.
另一方面，如上述專利文獻1、2所記載之前述環狀立體摺邊，其雖不易發生寬度方向之倒塌，但由於往肌膚側之突出高度不足，裝著時肌膚面與環狀立體摺邊間會產生縫隙，而有體液可能會由此縫隙漏出之虞。
On the other hand, the annular three-dimensional hemming described in the above-mentioned Patent Documents 1 and 2, although it is not easy to collapse in the width direction, the skin surface and the annular three-dimensional fold are folded due to the insufficient protrusion height to the skin side. There will be gaps between the sides, and there is a risk that body fluids may leak from this gap.
此外，上述專利文獻1、2所記載之環狀立體摺邊中，主要係藉由配置於環部上部之線狀彈性部材的收縮力，使形成環狀立體摺邊的片材部材朝穿用者的肌膚側被拉起，從而形成中空環部，但如此之環部，係一種僅會在穿用者股下部的吸收性物品於前後方向上大幅彎曲變形之區間形成，於較之前側及後側之區間，環部上部的線狀彈性部材的收縮力並不怎麼發揮作用，難以形成環部的構造。此外，若為了提高環部的突出高度而提高線狀彈性部材的張力，則有肌膚觸感變差，並產生不適感之虞。
In addition, in the ring-shaped three-dimensional hemming described in Patent Documents 1 and 2 above, the sheet member forming the ring-shaped three-dimensional hemming is mainly worn by the shrinking force of the linear elastic member disposed on the upper part of the ring. The skin side of the wearer is pulled up to form a hollow ring, but such a ring is formed in a section where the absorbent article that is only on the lower part of the wearer’s thighs bends and deforms significantly in the front and rear direction, and is formed on the front side and In the section on the rear side, the shrinking force of the linear elastic member on the upper part of the ring part does not exert much effect, and it is difficult to form the structure of the ring part. In addition, if the tension of the linear elastic member is increased in order to increase the protrusion height of the ring portion, the touch of the skin may be deteriorated and there is a possibility that a feeling of discomfort may occur.
有鑑於此，本發明的主要課題在於提供一種吸收性物品，其係於具備中空的環狀立體摺邊之吸收性物品中，提高立體摺邊的突出高度從而防止外漏，同時減輕不適感。
In view of this, the main subject of the present invention is to provide an absorbent article, which is an absorbent article provided with a hollow ring-shaped three-dimensional hem, which increases the protrusion height of the three-dimensional hem to prevent leakage and reduce discomfort.

In addition, in the example shown in the figure, in order to maintain the shape of the absorbent body 4 and improve the diffusibility, the absorbent body 4 is surrounded by a wrapping sheet 5 made of crepe paper or non-woven fabric, but even if there is no such wrapping sheet Material 5 is also possible. In addition, although not shown in the figure, it may be adjacent to the non-skin side of the liquid-permeable surface sheet 3, and a hydrophilic nonwoven fabric having almost the same shape as the liquid-permeable surface sheet 3 may be arranged. Two sheets.
以下進一步對前述生理用衛生棉1的構造進行詳細說明：
The structure of the aforementioned sanitary napkin 1 will be further described in detail below:
前述不透液性背面片材2，雖係使用聚乙烯等至少具有阻水性的片
材，但從防止悶熱的觀點而言，理想係使用具有透濕性者。此阻水、透濕性片材，理想係使用微多孔性片材，該微多孔性片材係於聚乙烯或聚丙烯等烯烴系樹脂中熔融混練無機填充劑，使片材成形後，藉由向一軸或二軸方向延伸而獲得。前述不透液性背面片材2的非肌膚側面(外面)沿衛生棉長邊方向形成有一或複數條黏著劑層(未圖示)，使生理用衛生棉1於裝著於身體時會固定於內褲。前述不透液性背面片材2，亦可使用塑膠膜與不織布積層而成的聚乙烯積層不織布。
The aforementioned liquid-impermeable back sheet 2, although it is a sheet with at least water resistance such as polyethylene
However, from the viewpoint of preventing stuffiness, it is ideal to use those with moisture permeability. This water-blocking and moisture-permeable sheet is ideally a microporous sheet, which is melted and kneaded with an olefin resin such as polyethylene or polypropylene, and an inorganic filler is formed after the sheet is formed. Obtained by extending to one axis or two axes. The non-skin side (outer surface) of the aforementioned liquid-impermeable back sheet 2 is formed with one or more adhesive layers (not shown) along the long side of the sanitary napkin, so that the sanitary napkin 1 is fixed when it is installed on the body In underwear. The aforementioned liquid-impermeable back sheet 2 may also be a polyethylene laminated non-woven fabric formed by laminating a plastic film and a non-woven fabric.
接著，前述透液性表面片材3，理想係使用有孔或無孔的不織布或多孔性塑膠片材等。構成不織布的素材纖維，除了聚乙烯或聚丙烯等之烯烴系、聚酯系、聚醯胺系等之合成纖維以外，亦可為嫘縈或銅銨等之再生纖維、棉等之天然纖維，且可使用由水針法、紡黏法、熱熔黏合法、熔噴法、針軋法等適當之加工法所獲得之不織布。此等之加工法中，水針法之優點在於富有柔軟性、懸垂性，熱熔黏合法之優點在於蓬鬆而壓縮復原性高。於前述透液性表面片材3形成多數透孔之情形，體液會被迅速吸收，乾爽性優異。不織布的纖維，可為長纖維或短纖維任一者，但理想係以使用短纖維以呈現毛巾質地的質感為佳。此外，為了便於壓紋處理，以使用熔點較低的聚乙烯或聚丙烯等之烯烴系纖維者為佳。此外，亦可理想地使用將熔點高的纖維作為芯而熔點低的纖維作為鞘的芯鞘型纖維、或並列型纖維、分割型纖維之複合纖維。
Next, for the aforementioned liquid-permeable surface sheet 3, it is desirable to use a porous or non-porous non-woven fabric, a porous plastic sheet, or the like. In addition to synthetic fibers such as polyethylene or polypropylene, such as olefin, polyester, and polyamide, the material fibers constituting the non-woven fabric may also be recycled fibers such as rayon or cupra, and natural fibers such as cotton. And can use non-woven fabrics obtained by appropriate processing methods such as water needle method, spun bonding method, hot melt bonding method, melt blown method, and needle rolling method. Among these processing methods, the advantages of the water jet method are flexibility and drape, and the advantages of the hot melt bonding method are that it is fluffy and has high compression recovery. In the case where a large number of through holes are formed in the aforementioned liquid-permeable surface sheet 3, body fluids are quickly absorbed, and the dryness is excellent. The fibers of the non-woven fabric can be either long fibers or short fibers, but it is ideal to use short fibers to present a towel-like texture. In addition, in order to facilitate the embossing process, it is better to use olefin fibers such as polyethylene or polypropylene with a lower melting point. In addition, it is also desirable to use a core-sheath type fiber having a fiber with a high melting point as a core and a fiber with a low melting point as a sheath, or a composite fiber of a side-by-side type fiber and a split type fiber.
介於前述不透液性背面片材2與透液性表面片材3之間的吸收體4，例如係由棉狀紙漿與吸水性聚合物所構成。前述吸水性聚合物係例如作為粒狀粉，混入構成吸收體的紙漿中。前述紙漿，可列舉：由從
木材所獲得之化學紙漿、溶解紙漿等之纖維素纖維、或嫘縈、醋酸酯等之人工纖維素纖維所成者，相較於闊葉樹紙漿，就功能及價格面而言，更理想為使用纖維長度較長的針葉樹紙漿。前述吸收體4的基重為300~750g/m2，理想係以設為300~400g/m2為佳。
The absorbent body 4 interposed between the aforementioned liquid-impermeable back sheet 2 and the liquid-permeable surface sheet 3 is composed of, for example, cotton-like pulp and a water-absorbing polymer. The aforementioned water-absorbing polymer system is, for example, as a granular powder, mixed in the pulp constituting the absorbent body. The aforementioned pulps include: chemical pulp obtained from wood, cellulose fibers such as dissolving pulp, or artificial cellulose fibers such as rayon and acetate.

5, 6 (C) and 7 of the embodiment, the third joining part 27 is to join the third sheet part 24 and the second sheet part 23 almost across the entire width, but at least It is provided at a position close to the first reverse-folded portion 20 that overlaps with the aforementioned elastic sheet 13 for free end portions, and it is not necessary to provide it on the side closer to the second reverse-folded portion 21.
處於前述彈性部材13、14的收縮力作用之自然狀態中的前述托起用立體摺邊11的自由端部12，如圖2所示，理想係至少在對應於穿用者股下之長邊區間中，位於前述環狀立體摺邊10朝穿用者肌膚側突出得最高的部分。對應於穿用者股下部之長邊區間，係生理用衛生棉1於長邊方向上彎曲變形得最大，且藉由沿長邊方向配置之彈性部材的收縮
力，使立體摺邊BS被朝肌膚側拉起得最高的部分。於此，前述托起用立體摺邊11的自由端部12，由於被配置為於環狀立體摺邊10的中空內部中可自由地改變位置，因此於環狀立體摺邊10的中空內部中，容易移動至朝穿用者肌膚側突出得最高的部分，藉由托起用立體摺邊11使其自內側托起以輔助環狀立體摺邊10往肌膚側之突出，從而使環狀立體摺邊10更加地朝肌膚側高度突出，並使與穿用者肌膚面密著的狀態得以維持。藉此，增進體液外漏防止效果。
The free end 12 of the supporting three-dimensional hemming 11 in the natural state where the contraction force of the elastic members 13 and 14 acts, as shown in FIG. 2, is ideally at least in the long side section corresponding to the wearer's thigh , Located at the part where the aforementioned ring-shaped three-dimensional hem 10 protrudes highest toward the wearer's skin. Corresponding to the long side section of the lower part of the wearer’s thigh, the sanitary napkin 1 has the largest bending deformation in the long side direction, and is contracted by the elastic members arranged in the long side direction
Force, so that the three-dimensional hem BS is pulled up the highest part to the skin side. Here, since the free end 12 of the three-dimensional hemming 11 for holding up is arranged to be freely changeable in the hollow interior of the ring-shaped three-dimensional hemming 10, in the hollow interior of the ring-shaped three-dimensional hemming 10, It is easy to move to the most protruding part toward the skin side of the wearer, and the three-dimensional hem 11 is lifted up from the inside to assist the protruding of the ring-shaped three-dimensional hem 10 to the skin side, thereby making the ring-shaped three-dimensional hem 10 is more highly protruding toward the skin side, and maintains the state of being close to the wearer's skin. In this way, the effect of preventing body fluid leakage is improved.
從更加顯著地發揮如此效果的觀點而言，亦可將配置於托起用立體摺邊11之自由端部12的自由端部用彈性部材13的伸長率，設為較配置於環狀立體摺邊10的環部之環部用彈性部材14的伸長率大。藉此，可進一步提高以托起用立體摺邊11托起環狀立體摺邊10的效果，並使環狀立體摺邊10變得更朝肌膚側突出。此外，配置於環狀立體摺邊10的環部用彈性部材14，由於係與肌膚面直接接觸，故若提高伸長率，會使其對肌膚面的肌膚觸感惡化，裝著感降低，但配置於托起用立體摺邊11之自由端部12的自由端部用彈性部材13，係介由環狀立體摺邊10與肌膚面接觸，因此即使提高伸長率，亦不會發生裝著感大幅降低之情形。前述自由端部用彈性部材13的伸長率，相對於環部用彈性部材14的伸長率，為1~3倍，理想係以設為1.2~2倍為佳。
From the viewpoint of more remarkably exerting such an effect, the elongation rate of the free end elastic member 13 arranged at the free end 12 of the lifting three-dimensional hemming 11 may be set to be higher than that of the free end elastic member 13 arranged in the ring three-dimensional hemming The elastic member 14 for the ring portion of the ring portion 10 has a large elongation. Thereby, the effect of holding up the ring-shaped three-dimensional hem 10 with the holding-up three-dimensional hem 11 can be further improved, and the ring-shaped three-dimensional hem 10 can become more protruding toward the skin side. In addition, the elastic member 14 for the ring portion arranged in the ring-shaped three-dimensional hem 10 is in direct contact with the skin surface. Therefore, if the elongation is increased, the skin touch on the skin surface will be deteriorated and the wearing feeling will be reduced. The free end elastic member 13 arranged at the free end 12 of the lifting three-dimensional hem 11 is in contact with the skin surface through the ring-shaped three-dimensional hem 10, so even if the elongation is increased, the wearing feeling will not be large. Reduced situation. The elongation rate of the elastic member 13 for the free end portion is 1 to 3 times the elongation rate of the elastic member 14 for the ring portion, and preferably 1.2 to 2 times.
圖8為表示變形例之摺邊片材7的寬度方向內方側部分之折疊狀態的斷面圖，圖9為表示其立起狀態的生理用衛生棉1之橫斷面圖。此變形例中，係使配置於環狀立體摺邊10之環部的環部用彈性部材14，於環狀立體摺邊10的環部中，不配置於生理用衛生棉1的寬度方向
內方側。配置於環狀立體摺邊10之環部的環部用彈性部材14中，配置於環狀立體摺邊10之寬度方向中央部的環部用彈性部材14以外的環部用彈性部材14，亦即各自配置於生理用衛生棉1之寬度方向內方側及寬度方向外方側的環部用彈性部材14，由於在將環狀立體摺邊10往肌膚側拉起的力作用的同時，將中空之環部拓寬的方向的力亦作用，因此存在藉由此將中空之環部拓寬方向之力的成分使環狀立體摺邊10往肌膚側之突出高度降低的作用。因此，如上所述，藉由不將環部用彈性部材14於環狀立體摺邊10的環部中配置在生理用衛生棉1的寬度方向內方側，使寬度方向內方側之環狀立體摺邊10的突出高度不降低。
8 is a cross-sectional view showing the folded state of the inner side portion in the width direction of the hemmed sheet 7 of the modified example, and FIG. 9 is a cross-sectional view of the sanitary napkin 1 showing the erected state. In this modification, the ring elastic member 14 arranged on the ring portion of the ring-shaped three-dimensional hemming 10 is not arranged in the width direction of the sanitary napkin 1 in the ring portion of the ring-shaped three-dimensional hemming 10
Inner side. Among the elastic members 14 for the ring portion arranged at the ring portion of the ring-shaped three-dimensional hemming 10, the elastic members 14 for the ring portion other than the elastic member 14 for the ring portion arranged at the center of the width direction of the ring-shaped three-dimensional hemming 10 are also That is, the elastic members 14 for the loops respectively arranged on the inner side in the width direction and the outer side in the width direction of the sanitary napkin 1 are exerted by the force that pulls the ring-shaped three-dimensional hemming 10 to the skin side and simultaneously The force in the direction in which the hollow ring portion is widened also acts, so there is an effect of reducing the protrusion height of the ring-shaped three-dimensional hem 10 toward the skin side by the component of the force in the direction in which the hollow ring portion is widened. Therefore, as described above, by not arranging the ring portion elastic member 14 in the ring portion of the ring-shaped three-dimensional hemming 10 on the inner side in the width direction of the sanitary napkin 1, the ring on the inner side in the width direction The protrusion height of the three-dimensional folded edge 10 does not decrease.
另一方面，作為其他變形例，如圖10及圖11所示，亦可於前述環狀立體摺邊10設置有使沿環部相鄰之環部用彈性部材14的配置間隔較其他區間相對狹窄的區間。藉由設置使環部用彈性部材14的配置間隔變狹窄的區間，此部分變得容易朝肌膚側突出，可更加提高體液外漏防止效果。環部用彈性部材14的配置間隔變狹窄的區間，只要沿環部之環設置於任一部分之區間皆可，理想係如圖示例般，設置於生理用衛生棉1的寬度方向內方側。藉此，於環狀立體摺邊10的寬度方向內方側，會形成朝向肌膚側幾乎垂直立起的壁面，使流向寬度方向外方側的體液可藉由環狀立體摺邊10確實地被堵住。
On the other hand, as another modified example, as shown in FIGS. 10 and 11, the annular three-dimensional hemming 10 may be provided with the elastic member 14 for the ring portion adjacent to the ring portion at an interval relative to other sections. Narrow interval. By providing a section that narrows the arrangement interval of the elastic member 14 for the ring section, this section becomes easy to protrude toward the skin side, and the effect of preventing body fluid leakage can be further improved. The section where the arrangement interval of the elastic member 14 for the ring portion is narrowed can be provided in any part of the section along the ring of the ring portion. Ideally, it is installed on the inner side in the width direction of the sanitary napkin 1 as shown in the example. . Thereby, on the inner side in the width direction of the ring-shaped three-dimensional hem 10, a wall surface that rises almost perpendicular to the skin side is formed, so that the body fluid flowing to the outer side in the width direction can be reliably absorbed by the ring-shaped three-dimensional hem 10 Blocked.
