A diagram of the state of the member's elongation.
用後即棄式紙尿布10具有前腰圍區域20、***區域25及後腰圍區域30。前腰圍區域20係與穿用者的前腰圍部(腹部分)相接的部分。且,後腰圍區域30係與穿用者的後腰圍部(背部分)相接的部分。***區域25位於前腰圍區域20和後腰圍區域30之間。 The disposable disposable diaper 10 has a front waistline region 20, a crotch region 25 and a rear waistline region 30. The front waistline region 20 is a portion that is in contact with the front waistline (abdominal portion) of the wearer. Further, the rear waistline region 30 is a portion that is in contact with the wearer's rear waistline portion (back portion). The crotch region 25 is located between the front waistline region 20 and the rear waistline region 30.
在用後即棄式紙尿布10形成一對腿部開口部35。腿部開口部35係設置在用後即棄式紙尿布的寬度方向的側端部,於用後即棄式紙尿布穿著在穿用者的狀態,沿著穿用者的腿圍配置的部分。 The disposable disposable diaper 10 forms a pair of leg openings 35. The leg opening portion 35 is provided at the side end portion in the width direction of the disposable disposable diaper, and the disposable diaper is worn in the state of the wearer after use, and is disposed along the leg circumference of the wearer. .
此外,本實施形態中,從前腰圍區域20朝向後腰圍區域30的方向稱為長度方向L,與長度方向L正 交的方向稱為寬度方向W。 Further, in the present embodiment, the direction from the front waistline region 20 toward the rear waistline region 30 is referred to as the longitudinal direction L, and the longitudinal direction is positive. The direction of intersection is called the width direction W.
用後即棄式紙尿布10具有吸收體40。吸收體40具有吸收芯40a和芯包層40b。吸收芯40a橫跨***區域25,且從***區域25朝向前腰圍區域20及後腰圍區域30當中至少一方延伸。 The disposable disposable diaper 10 has an absorbent body 40. The absorber 40 has an absorbent core 40a and a core cladding 40b. The absorbent core 40a extends across the crotch region 25 and extends from the crotch region 25 toward at least one of the front waistline region 20 and the rear waistline region 30.
吸收芯40a與現有的用後即棄式紙尿布同樣,可使用粉碎紙漿或高吸收聚合物等眾所周知的構件或材料適當構成。吸收芯40a係由薄片狀的芯包層40b包覆。芯包層40b係被覆吸收芯40a的薄片。吸收芯40a的後端緣和芯包層40b的後端緣大致一致,且吸收芯40a的前端緣和芯包層40b的前端緣大致一致。更詳細地說,吸收芯40a的後端緣和芯包層40b的後端緣的距離為5mm以下,吸收芯40a的前端緣和芯包層40b的前端緣的距離為5mm以下。 The absorbent core 40a can be suitably formed using a well-known member or material such as pulverized pulp or a superabsorbent polymer, similarly to the conventional disposable diaper. The absorbent core 40a is covered by a sheet-like core cladding 40b. The core cladding 40b is a sheet covering the absorbent core 40a. The rear end edge of the absorbent core 40a and the rear end edge of the core clad 40b substantially coincide, and the front end edge of the absorbent core 40a and the front end edge of the core clad 40b substantially coincide. More specifically, the distance between the rear end edge of the absorbent core 40a and the rear end edge of the core clad layer 40b is 5 mm or less, and the distance between the front end edge of the absorbent core 40a and the front end edge of the core clad layer 40b is 5 mm or less.
如圖4所示,在吸收芯40a形成有吸收材料的基重比吸收芯40a的其他部位更低的低基重區域110。低基重區域110位於吸收芯40a後端緣的寬度方向的中央。寬度方向W的低基重區域110的寬度隨著朝向吸收芯40a的後端緣而變寬。更具體而言,於俯視用後即棄式紙尿布10時,低基重區域110為楔子狀。藉由後述的腰圍伸縮部85而沿寬度方向收縮時,低基重區域110比周圍更容易收縮,吸收芯40a的後端部形成沿著穿用者的臀部的杯狀。 As shown in FIG. 4, the absorbent core 40a is formed with a low basis weight region 110 having a lower basis weight of the absorbent material than other portions of the absorbent core 40a. The low basis weight region 110 is located at the center in the width direction of the rear end edge of the absorbent core 40a. The width of the low basis weight region 110 in the width direction W is widened toward the rear end edge of the absorbent core 40a. More specifically, when the disposable diaper 10 is used in a plan view, the low basis weight region 110 has a wedge shape. When contracting in the width direction by the waist elastic portion 85 to be described later, the low basis weight region 110 is more easily contracted than the circumference, and the rear end portion of the absorbent core 40a is formed in a cup shape along the buttocks of the wearer.
在吸收體40的表面側(肌膚對向面側)具備 液透過性的頂部薄片50。且,在吸收體40的裏面側(非肌膚對向面側)具備不透液性的背部薄片60a。在背部薄片60a的裏面側具備外裝薄片60。背部薄片的前端緣位於比用後即棄式紙尿布的前端緣更後方,背部薄片的後端緣位於比用後即棄式紙尿布的後端緣更前方。 It is provided on the surface side (the opposite side of the skin) of the absorber 40 Liquid permeable top sheet 50. Further, a back sheet 60a which is liquid-impermeable is provided on the back side (non-skin facing side) of the absorber 40. An exterior sheet 60 is provided on the back side of the back sheet 60a. The front end edge of the back sheet is located further rearward than the front end edge of the disposable disposable diaper, and the rear end edge of the back sheet is located further forward than the trailing edge of the disposable disposable diaper.
在吸收體40的外側緣(寬度方向的外側端)分別具備側翼70。側翼70橫跨前腰圍區域20、***區域25、以及後腰圍區域30,且配置在比吸收體40更靠寬度方向的外側。側翼70係藉由1片或2片以上的複數片重疊的不織布而構成。側翼70位於比吸收芯40a更靠肌膚對向面側,朝比吸收芯40a更靠寬度方向的外側延伸。 The side edges 70 are provided in the outer edge (outer end in the width direction) of the absorber 40, respectively. The side flaps 70 straddle the front waistline region 20, the crotch region 25, and the rear waistline region 30, and are disposed outside the absorbent body 40 in the width direction. The side flaps 70 are constituted by one or two or more sheets of non-woven fabrics that are overlapped. The side flap 70 is located on the skin facing surface side of the absorbent core 40a, and extends outward in the width direction from the absorbent core 40a.

且,用後即棄式紙尿布10具備配置在與***區域25的吸收體重疊的區域的褲襠伸縮部200。褲襠伸縮部200構成為,相較於吸收體40的其他部分,在用後即棄式紙尿布的穿用時更能在***區域25的一部分維持平坦的形狀。褲襠伸縮部200構成為至少能在長度方向L或寬度方向W伸縮。 Further, the disposable disposable diaper 10 includes a crotch elasticized portion 200 disposed in a region overlapping the absorbent body of the crotch region 25. The crotch stretchable portion 200 is configured to maintain a flat shape in a portion of the crotch region 25 when worn, as compared with other portions of the absorbent body 40. The crotch stretch unit 200 is configured to be expandable and contractable at least in the longitudinal direction L or the width direction W.
在***區域25的吸收芯40a形成第1缺口115及第2缺口125。第1缺口115及第2缺口125係形成在吸收芯40a的縫隙。縫隙為吸收材料不存在的部分。第1缺口115及第2缺口125係分別從吸收芯40a的外側緣朝向寬度方向的內側延伸的缺口形狀。 The first notch 115 and the second notch 125 are formed in the absorbent core 40a of the crotch region 25. The first notch 115 and the second notch 125 are formed in the gap of the absorbent core 40a. The gap is the portion where the absorbing material does not exist. The first notch 115 and the second notch 125 are each formed in a notch shape extending from the outer edge of the absorbent core 40a toward the inner side in the width direction.
黏扣帶90為一對,在後腰圍區域30沿著寬度方向W延伸,固定於前腰圍區域20的非肌膚對向面,藉此將用後即棄式紙尿布10保持於穿用者的身體。黏扣帶90裝設在與後腰圍區域30對應的側翼70的區域。黏扣帶90具備:連結於側翼70的基材薄片91、及設置有複數個卡合鈎(不圖示)而固定於基材薄片91的鈎薄片92。鈎薄片92係設有卡合鈎的區域。 The fastening tape 90 is a pair and extends in the width direction W in the rear waistline region 30 and is fixed to the non-skin opposing surface of the front waistline region 20, thereby holding the disposable disposable diaper 10 to the wearer's body. The fastening strip 90 is mounted in the region of the side flaps 70 corresponding to the rear waistline region 30. The fastening tape 90 includes a base sheet 91 that is coupled to the side flaps 70, and a hook sheet 92 that is fixed to the base sheet 91 by a plurality of engagement hooks (not shown). The hook sheet 92 is provided with a region in which the hook is engaged.
目標部95設置在前腰圍區域20的外裝薄片60的非肌膚對向側的面。目標部95構成為讓黏扣帶90的卡合鈎卡住,作為鈎和迴圈的卡止系統的迴圈之功能。目標部95例如可使用熱風不織布。此外,用後即棄式紙尿布亦可構成為將黏扣帶90固定於前腰圍區域20的外裝薄片60,而不具有目標部。 The target portion 95 is provided on the non-skin opposing side surface of the exterior sheet 60 of the front waistline region 20. The target portion 95 is configured to engage the engagement hook of the fastening tape 90 as a function of the loop of the hook and loop locking system. The target portion 95 can use, for example, a hot air non-woven fabric. Further, the disposable disposable diaper may be configured to fix the fastening tape 90 to the exterior sheet 60 of the front waistline region 20 without having a target portion.
用後即棄式紙尿布10具有能沿寬度方向伸縮的腰圍伸縮部。腰圍伸縮部85配置在後腰圍區域。腰圍伸縮部85配置在寬度方向的一對黏扣帶90間,在黏扣帶90間沿寬度方向收縮。腰圍伸縮部85的前端緣係寬度方向中心朝向後方凹陷的曲線形狀。 The disposable disposable diaper 10 has a waist elasticized portion that can expand and contract in the width direction. The waist elasticized portion 85 is disposed in the rear waist region. The waist elastic-contraction portion 85 is disposed between the pair of fastening tapes 90 in the width direction, and is contracted in the width direction between the fastening tapes 90. The front end edge of the waist elasticized portion 85 has a curved shape in which the center in the width direction is recessed toward the rear.
本實施形態中,腰圍伸縮部係藉由伸縮性薄片構成,例如可使用伸縮薄膜、伸縮不織布及胺基甲酸酯。腰圍伸縮部85亦可藉由伸縮不織布構成。由伸縮不織布構成的腰圍伸縮部85相較於由伸縮薄膜構成的腰圍伸縮部,容易維持嬰幼兒的腰部周圍的通氣性。此外,腰圍伸縮部係實質上沿寬度方向伸縮的部分,於未發揮伸縮力的狀態下去除配置有伸縮性薄片的部分之概念。因此,後述腰圍伸縮部的外側緣並非伸縮薄片的外側緣,而是進行伸縮的部分的外側緣。本實施形態中,腰圍伸縮部係使用基重為20~45g/m2的伸縮性薄膜。但是,腰圍伸縮部85亦可藉由複數條橡膠線等其他構造來構成。腰圍伸縮部係於被拉伸到相對於非伸展狀態(自然狀態)的長度之既定倍率後,藉由熱熔接著劑或加熱處理等而接著於背部 薄片60a。關於腰圍伸縮部,於後述詳細地說明。 In the present embodiment, the waist elasticized portion is formed of a stretchable sheet, and for example, a stretch film, a stretchable nonwoven fabric, and a urethane can be used. The waist elasticized portion 85 can also be constituted by a stretchable nonwoven fabric. The waist elastic portion 85 composed of the stretchable nonwoven fabric is more likely to maintain the air permeability around the waist of the infant than the waist stretchable portion formed of the stretch film. Further, the waist elastic-contracting portion is a portion that substantially expands and contracts in the width direction, and removes the concept of the portion in which the stretchable sheet is disposed without exhibiting the expansion and contraction force. Therefore, the outer edge of the waist stretchable portion to be described later is not the outer edge of the stretch sheet, but the outer edge of the portion that expands and contracts. In the present embodiment, a stretchable film having a basis weight of 20 to 45 g/m 2 is used for the waist stretchable portion. However, the waist elastic-contraction portion 85 may be configured by other structures such as a plurality of rubber threads. The waist stretchable portion is attached to the back sheet 60a by a hot melt adhesive or heat treatment after being stretched to a predetermined magnification with respect to the length of the non-stretched state (natural state). The waist expansion and contraction portion will be described in detail later.
且,在用後即棄式紙尿布,設置有複數個接合腰圍伸縮部和薄片材的接合部。接合部87係接合腰圍伸縮部85及與腰圍伸縮部85重疊的薄片材。關於接合部,於後述詳細地說明。 Further, in the disposable disposable diaper, a plurality of joint portions for joining the waist elasticized portion and the sheet member are provided. The joint portion 87 joins the waist stretchable portion 85 and the sheet material that overlaps the waist stretchable portion 85. The joint portion will be described in detail later.
外裝薄片的後腰圍區域的外側緣位於比外裝薄片的前腰圍區域的外側緣更靠寬度方向的外側。外裝薄片的外側緣係在用後即棄式紙尿布去除黏扣帶後的區域的外側緣。外裝薄片的後腰圍區域的寬度方向的長度比外裝薄片的前腰圍區域的寬度方向的長度更長。因此,將黏扣帶固定於前腰圍區域時,容易將後腰圍區域的外側緣拉近穿用者的身體的前側。藉由將後腰圍區域的外側緣拉近穿用者的身體的前側,腰圍伸縮部伸長而能將用後即棄式紙尿布的後端緣貼合於穿用者的身體。 The outer edge of the rear waistline region of the outer sheet is located outside the outer edge of the front waistline region of the outer sheet in the width direction. The outer edge of the outer sheet is the outer edge of the area after the disposable diaper is removed to remove the adhesive strip. The length of the rear waistline region of the outer sheet in the width direction is longer than the length of the front waistline region of the outer sheet in the width direction. Therefore, when the fastening tape is fixed to the front waistline region, the outer edge of the rear waistline region is easily pulled closer to the front side of the wearer's body. By pulling the outer edge of the rear waist region to the front side of the wearer's body, the waist stretchable portion is extended, and the rear end edge of the disposable disposable diaper can be attached to the wearer's body.
外裝薄片的寬度方向的長度係從***區域朝向用後即棄式紙尿布的後端緣變長。更詳細地說,配置有一對黏扣帶的區域的外裝薄片寬度方向的長度,相較於比吸收芯的低基重區域更靠前方的區域的外裝薄片寬度方向的長度更長。由於配置有黏扣帶的區域係寬度方向的長度較長,即使因為腰圍伸縮部收縮,黏扣帶仍容易位於比吸收芯更靠寬度方向外側。吸收芯為裝設時放置穿用者的區域。藉由將黏扣帶配置在比吸收芯更靠寬度方向的外側,防止黏扣帶被配置在穿用者的身體和吸收芯之間,而能抑制黏扣帶造成對肌膚的刺激。 The length of the outer sheet in the width direction is lengthened from the crotch region toward the rear end edge of the disposable disposable diaper. More specifically, the length of the outer sheet in the region in which the pair of fastening tapes are disposed is longer in the width direction of the outer sheet than in the region lower than the low basis weight region of the absorbent core. Since the length of the region in which the fastening tape is disposed is long in the width direction, even if the waist elastic portion contracts, the fastening tape is likely to be located outside the width direction of the absorbent core. The absorbent core is the area where the wearer is placed when installed. By arranging the adhesive tape on the outer side in the width direction of the absorbent core, the adhesive tape is prevented from being disposed between the wearer's body and the absorbent core, and the adhesive tape is prevented from causing irritation to the skin.
腰圍伸縮部85係從用後即棄式紙尿布的寬度方向的中心朝向寬度方向的兩外側延伸,藉由朝寬度方向延伸的伸縮性薄片構成。本實施形態之腰圍伸縮部係構成為沿寬度方向伸縮,但腰圍伸縮部亦可構成為沿寬度方向和長度方向伸縮。 The waist stretchable portion 85 extends from the center in the width direction of the disposable disposable diaper toward both outer sides in the width direction, and is formed of a stretchable sheet extending in the width direction. The waist elasticized portion of the present embodiment is configured to expand and contract in the width direction, but the waist elasticized portion may be configured to expand and contract in the width direction and the longitudinal direction.
腰圍伸縮部85的後端緣與用後即棄式紙尿布的後端緣一致。腰圍伸縮部85的前端緣位於比吸收芯40a的後端緣更靠前側,且位於比芯包層40b的後端緣更靠前側。於用後即棄式紙尿布的俯視觀察,腰圍伸縮部85的至少一部分係與吸收芯40a重疊。且,腰圍伸縮部85橫跨吸收芯40a的後端緣及芯包層40b的後端緣,比吸收芯40a的後端緣及芯包層40b的後端緣更朝前側延伸。腰圍伸縮部85的外側緣位於比黏扣帶的內側緣(寬度方向的內側端)更靠寬度方向的內側。腰圍伸縮部85和黏扣帶90在寬度方向分開。藉由腰圍伸縮部85和黏扣帶90在寬度方向分開,穿用者較容易掌握腰圍伸縮部可伸縮的餘地,而較容易操作黏扣帶。 The rear end edge of the waist elastic portion 85 coincides with the rear end edge of the disposable disposable diaper. The front end edge of the waist stretchable portion 85 is located on the front side of the rear end edge of the absorbent core 40a, and is located on the front side of the rear end edge of the core wrap 40b. At least a portion of the waist stretchable portion 85 overlaps the absorbent core 40a in a plan view of the disposable disposable diaper. Further, the waist stretchable portion 85 extends across the rear end edge of the absorbent core 40a and the rear end edge of the core wrap 40b, and extends further toward the front side than the rear end edge of the absorbent core 40a and the rear end edge of the core clad 40b. The outer edge of the waist elasticized portion 85 is located on the inner side in the width direction of the inner edge (the inner end in the width direction) of the fastening tape. The waist elastic portion 85 and the fastening tape 90 are separated in the width direction. By separating the waist elastic-contraction portion 85 and the fastening tape 90 in the width direction, it is easier for the wearer to grasp the room for the waist-contracting portion to expand and contract, and it is easier to operate the fastening tape.
腰圍伸縮部位於比吸收芯40a更靠非肌膚對向面側。本實施形態中,腰圍伸縮部配置在外裝薄片60和背部薄片60a之間。腰圍伸縮部的位置未有特別限定。且,在未配置吸收體的區域,亦可配置在側翼70、及背部薄片60a或外裝薄片60之間。本實施形態中,位於腰 圍伸縮部的肌膚對向面側的肌膚面薄片包含頂部薄片50、側翼70及背部薄片60a。位於腰圍伸縮部的非肌膚對向面側的非肌膚面薄片包含外裝薄片60。 The waist elasticized portion is located on the non-skin opposing side of the absorbent core 40a. In the present embodiment, the waist stretchable portion is disposed between the exterior sheet 60 and the back sheet 60a. The position of the waist elasticized portion is not particularly limited. Further, the region where the absorber is not disposed may be disposed between the side flaps 70 and the back sheet 60a or the exterior sheet 60. In this embodiment, it is located at the waist The skin surface sheet on the skin facing side of the surrounding stretchable portion includes a top sheet 50, side flaps 70, and a back sheet 60a. The non-skin surface sheet on the non-skin facing surface side of the waist elasticized portion includes the exterior sheet 60.
在配置有腰圍伸縮部的區域形成有接合部。接合部形成在配置有腰圍伸縮部85的區域。接合部87係藉由熱密封接合腰圍伸縮部85、及與腰圍伸縮部85重疊的薄片材。此外,接合部不僅是藉由熱密封接合的部分,也可以是藉由超音波熔接等其他熔接方法或接著劑所接合的部分。 A joint portion is formed in a region where the waist elasticized portion is disposed. The joint portion is formed in a region where the waist elastic portion 85 is disposed. The joint portion 87 is a heat-sealed joint of the waist stretchable portion 85 and the sheet material that overlaps the waist stretchable portion 85. Further, the joint portion is not only a portion joined by heat sealing, but may be a portion joined by another welding method such as ultrasonic welding or an adhesive.
所謂薄片材,具體而言是頂部薄片50、側翼70、背部薄片60a、以及外裝薄片60。在頂部薄片50和腰圍伸縮部重疊的區域,接合部接合頂部薄片50、腰圍伸縮部、背部薄片60a、以及外裝薄片60。在側翼70和腰圍伸縮部重疊的區域,接合部接合側翼70、腰圍伸縮部、背部薄片60a、以及外裝薄片60。 The sheet material is specifically a top sheet 50, a side flap 70, a back sheet 60a, and an exterior sheet 60. In the region where the top sheet 50 and the waist stretch unit overlap, the joint portion joins the top sheet 50, the waist stretch unit, the back sheet 60a, and the exterior sheet 60. The joint portion joins the side flap 70, the waist stretchable portion, the back sheet 60a, and the exterior sheet 60 in a region where the side flap 70 and the waist stretchable portion overlap.
於用後即棄式紙尿布的俯視觀察,接合部87為點狀。藉由熱密封形成的接合部由於薄膜化,使得該部分的通氣性降低。藉由將接合部配置成點狀,能夠在接合部的周圍區域確保通氣性,抑制腰圍的通氣性降低。接合部87係沿著長度方向L並排。接合部具有:配置在後述第4區域R4的中央接合部871、及配置在後述第3區域R3的側接合部872。中央接合部871相對於與寬度方向相鄰的中央接合部871,係長度方向的位置偏離。即,中央接合部871被配置成格子狀。設置有接合部的部分相較於 未設有接合部的部分,其剛性較高,腰圍伸縮部的伸縮性降低。由於中央接合部871被配置成格子狀,相較於中央接合部871被連續配置的構成,能抑制寬度方向的應力降低並且提升沿著長度方向的剛性。 The joint portion 87 has a dot shape in a plan view of the disposable paper diaper after use. The joint formed by heat sealing is thinned, so that the air permeability of the portion is lowered. By arranging the joint portion in a dot shape, it is possible to ensure air permeability in the peripheral region of the joint portion and to suppress a decrease in the air permeability of the waist circumference. The joint portions 87 are arranged side by side in the longitudinal direction L. The joint portion has a center joint portion 871 disposed in a fourth region R4 to be described later, and a side joint portion 872 disposed in a third region R3 to be described later. The central joint portion 871 is displaced from the center joint portion 871 adjacent to the width direction in the longitudinal direction. That is, the center joint portion 871 is arranged in a lattice shape. Compared with the part provided with the joint The portion where the joint portion is not provided has high rigidity and the stretchability of the waist stretchable portion is lowered. Since the center joint portion 871 is arranged in a lattice shape, compared with the configuration in which the center joint portion 871 is continuously disposed, the stress reduction in the width direction can be suppressed and the rigidity in the longitudinal direction can be improved.
側接合部872與在寬度方向相鄰的側接合部872,係長度方向的位置一致。中央接合部871及側接合部872係沿著長度方向L及寬度方向W隔著間隔配置。中央接合部871的長度方向的間隔D1比側接合部872的長度方向的間隔D2更大。中央接合部871的寬度方向的間隔D3比側接合部872的寬度方向的間隔D4更大。中央接合部871的長度方向的間隔D1與中央接合部的寬度方向的間隔D3一致。且,側接合部的長度方向的間隔D2與側接合部的寬度方向的間隔D4一致。 The side joint portion 872 is aligned with the side joint portion 872 adjacent to the width direction in the longitudinal direction. The center joint portion 871 and the side joint portion 872 are disposed at intervals along the longitudinal direction L and the width direction W. The interval D1 in the longitudinal direction of the center joint portion 871 is larger than the interval D2 in the longitudinal direction of the side joint portion 872. The interval D3 in the width direction of the center joint portion 871 is larger than the interval D4 in the width direction of the side joint portion 872. The interval D1 in the longitudinal direction of the center joint portion 871 coincides with the interval D3 in the width direction of the center joint portion. Further, the interval D2 in the longitudinal direction of the side joint portion coincides with the interval D4 in the width direction of the side joint portion.
接合部列87L係沿長度方向L隔著間隔配置的複數個接合部之列。接合部列87L係沿寬度方向隔著間隔設置有複數個。接合部列87L的前端緣與第2區域R2的後端緣一致。接合部列87L的後端緣配置在用後即棄式紙尿布的後端緣。接合部列87L具有:隔著間隔配置有中央接合部871的中央接合部列871L、及隔著間隔配置有側接合部872的側接合部列872L。中央接合部列871L係沿寬度方向隔著間隔配列複數個。中央接合部列871L的寬度方向的間隔比側接合部列872L的寬度方向的間隔更大。 The joint portion row 87L is a plurality of joint portions arranged at intervals in the longitudinal direction L. The joint portion row 87L is provided in plural at intervals in the width direction. The front end edge of the joint portion row 87L coincides with the rear end edge of the second region R2. The rear end edge of the joint portion row 87L is disposed at the rear end edge of the disposable disposable diaper. The joint portion row 87L has a center joint portion row 871L in which the center joint portion 871 is disposed with an interval therebetween, and a side joint portion row 872L in which the side joint portion 872 is disposed with a gap therebetween. The central joint portion row 871L is arranged in plural at intervals in the width direction. The interval in the width direction of the center joint portion row 871L is larger than the interval in the width direction of the side joint portion row 872L.
用後即棄式紙尿布具有:一對第1區域R1, 從腰圍伸縮部85的兩外側緣朝向寬度方向的內側延伸;第2區域R2,從腰圍伸縮部85的前端緣朝向後方延伸;複數個第3區域R3,位於比第1區域R1更靠寬度方向的內側並且位於比第2區域R2更後方;第4區域R4,在比第3區域R3更靠寬度方向的內側,從用後即棄式紙尿布的寬度方向的中心朝寬度方向外側延伸;以及複數個第5區域R5,位於第3區域R3和第4區域R4之間。圖4中,對第1區域R1、第2區域R2、第3區域R3、第4區域R4以及第5區域R5分別賦予不同的斜線。此外,本實施形態體的用後即棄式紙尿布係至少具有第1區域R1、第2區域R2、及第3區域R3為佳。 The disposable disposable diaper has a pair of first region R1, The two outer edges of the waist elastic-contraction portion 85 extend toward the inner side in the width direction; the second region R2 extends rearward from the front end edge of the waist elastic-contraction portion 85; and the plurality of third regions R3 are located wider than the first region R1.

第1區域R1配置在腰圍伸縮部85的外側緣的長度方向全區域,從該外側緣朝寬度方向的內側延伸。第1區域R1的內側緣與第2區域R2的外側緣一致,且與第3區域R3的外側緣(於配置有複數個第3區域R3的構成中,位於寬度方向最外側的第3區域R3的外側緣)一致。第1區域R1位於比吸收芯40a的外側緣更靠寬度方向的外側。第1區域R1的後端緣與腰圍伸縮部85的後端緣一致。第1區域R1的前端緣與腰圍伸縮部85的前端緣一致。第1區域R1位於比吸收芯40a更靠寬度方向的外側。且,在第1區域R1未設有接合部87。由於在第1區域R1未設有接合部87,因此能維持第1區域R1的腰圍伸縮部85的伸縮性。 The first region R1 is disposed in the entire lengthwise direction of the outer edge of the waist elasticized portion 85, and extends from the outer edge toward the inner side in the width direction. The inner edge of the first region R1 coincides with the outer edge of the second region R2, and the outer edge of the third region R3 (the third region R3 located at the outermost side in the width direction in the configuration in which the plurality of third regions R3 are disposed) The outer edge of the outer edge is consistent. The first region R1 is located outside the outer edge of the absorbent core 40a in the width direction. The rear end edge of the first region R1 coincides with the rear end edge of the waist elasticized portion 85. The front end edge of the first region R1 coincides with the front end edge of the waist elasticized portion 85. The first region R1 is located outside the absorbent core 40a in the width direction. Further, the joint portion 87 is not provided in the first region R1. Since the joint portion 87 is not provided in the first region R1, the stretchability of the waist stretchable portion 85 of the first region R1 can be maintained.
第1區域R1的至少一部分配置在從腿部伸縮 部75朝長度方向延伸的區域。從腿部伸縮部75朝長度方向延伸的區域,係藉由從3條橡膠線當中位於寬度方向的兩外側的橡膠線,分別朝長度方向延伸的2條延長線挾持的區域。 At least a portion of the first region R1 is disposed to be stretched from the leg The portion of the portion 75 that extends in the longitudinal direction.

The front end edge of the second region R2 coincides with the front end edge of the waist elasticized portion 85. At least a part of the second region R2 overlaps with a region having a higher basis weight of the absorbent core 40a (a region other than the low basis weight region) and a low basis weight region 110 of the absorbent core 40a. At least a portion of the second region R2 including the rear end edge of the second region R2 is located rearward of the absorbent core 40a. The outer edge of the second region R2 is located outside the absorbent core 40a in the width direction. The joint portion 87 is not provided in the second region R2. Since the joint portion 87 is not provided in the second region R2, the stretchability of the waist stretchable portion 85 of the second region R2 can be maintained.
第3區域R3係從第1區域R1的內側緣朝寬度方向內側延伸。第3區域R3的內側緣與第5區域R5的外側緣一致。第3區域R3係於寬度方向橫跨吸收芯40a的外側緣。第3區域R3的後端緣與腰圍伸縮部85的後端緣一致。第3區域R3的前端緣與第2區域R2的後端緣一致。第3區域R3位於比吸收芯40a更後方。在第 3區域R3設置有側接合部列872L。腰圍伸縮部85係隔著側接合部872與薄片材接合,在側接合部872的伸縮性降低。因此,第3區域R3的腰圍伸縮部85的伸縮性比未設有接合部的區域(第1區域R1、第2區域R2、以及第5區域R5)更低。 The third region R3 extends inward in the width direction from the inner edge of the first region R1. The inner edge of the third region R3 coincides with the outer edge of the fifth region R5. The third region R3 spans the outer edge of the absorbent core 40a in the width direction.

The waist elastic-contraction portion 85 is joined to the sheet material via the side joint portion 872, and the stretchability at the side joint portion 872 is lowered. Therefore, the stretchability of the waist stretchable portion 85 of the third region R3 is lower than the region where the joint portion is not provided (the first region R1, the second region R2, and the fifth region R5).
第4區域R4配置在一對第5區域R5之間。第4區域R4的外側緣與第5區域R5的內側緣一致。第4區域R4的後端緣與腰圍伸縮部85的後端緣一致。第4區域R4的前端緣與第2區域R2的後端緣一致。第4區域R4位於比吸收芯40a更後方。在第4區域R4設置有中央接合部列871L。第4區域R4的腰圍伸縮部85的伸縮性比未設有接合部的區域(第1區域R1、第2區域R2、以及第5區域R5)更低。 The fourth region R4 is disposed between the pair of fifth regions R5. The outer edge of the fourth region R4 coincides with the inner edge of the fifth region R5. The rear end edge of the fourth region R4 coincides with the rear end edge of the waist elastic portion 85. The front end edge of the fourth region R4 coincides with the rear end edge of the second region R2. The fourth region R4 is located rearward of the absorbent core 40a. A central joint portion row 871L is provided in the fourth region R4. The stretchable portion 85 of the waist region expansion portion 85 of the fourth region R4 is lower than the region (the first region R1, the second region R2, and the fifth region R5) where the joint portion is not provided.
中央接合部871的面積比側接合部872的面積更大。在第3區域R3設置有側接合部872,在第4區域R4設置有中央接合部871。第3區域R3中的每單位面積的接合部的面積,比第4區域R4中的每單位面積的接合部的面積更高。即,第3區域R3的接合部的面密度比第4區域R4的接合部的面密度更高。 The area of the central joint portion 871 is larger than the area of the side joint portion 872. A side joint portion 872 is provided in the third region R3, and a center joint portion 871 is provided in the fourth region R4. The area of the joint portion per unit area in the third region R3 is higher than the area of the joint portion per unit area in the fourth region R4. That is, the areal density of the joint portion of the third region R3 is higher than the surface density of the joint portion of the fourth region R4.
第5區域R5配置在一對第3區域R3之間。第5區域R5的後端緣與腰圍伸縮部85的後端緣一致。第5區域R5的前端緣與第2區域R2的後端緣一致。第5區域R5位於比吸收芯40a更後方。第4區域R4及第5區域R5位於比吸收芯40a的外側緣更靠寬度方向的內側。 在第5區域R5未設有接合部87。由於在第5區域R5未設有接合部87,因此能維持第5區域R5的腰圍伸縮部85的伸縮性。 The fifth region R5 is disposed between the pair of third regions R3. The rear end edge of the fifth region R5 coincides with the rear end edge of the waist elasticized portion 85. The front end edge of the fifth region R5 coincides with the rear end edge of the second region R2. The fifth region R5 is located rearward of the absorbent core 40a. The fourth region R4 and the fifth region R5 are located on the inner side in the width direction of the outer edge of the absorbent core 40a. The joint portion 87 is not provided in the fifth region R5. Since the joint portion 87 is not provided in the fifth region R5, the stretchability of the waist stretchable portion 85 of the fifth region R5 can be maintained.
且,腰圍伸縮部85具有伸長率高的區域和伸長率低的區域。具體地說,在腰圍伸縮部85的寬度方向中央配置伸長率較高的高伸展區域,在高伸展區域的寬度方向外側配置伸長率較低的低伸展區域,在低伸展區域的寬度方向外側配置高伸展區域。寬度方向中央的高伸展區域的外端緣為第5區域的外端緣。即,第4區域及第5區域為高伸展區域。低伸展區域的外端緣為第3區域的外端緣。即,第3區域為低伸展區域。且,第1區域為高伸展區域。 Further, the waist elastic-contraction portion 85 has a region having a high elongation and a region having a low elongation. Specifically, a high stretch region having a high elongation is disposed in the center in the width direction of the waist stretchable portion 85, and a low stretch region having a low elongation is disposed on the outer side in the width direction of the high stretch region, and is disposed outside the width direction of the low stretch region. High stretch area. The outer edge of the high stretch region in the center in the width direction is the outer edge of the fifth region. That is, the fourth region and the fifth region are high stretch regions. The outer edge of the low stretch region is the outer edge of the third region. That is, the third region is a low stretch region. Moreover, the first area is a high stretch area.
由於腰圍伸縮部的伸長率不同及接合部87的有無,使得腰圍伸縮部85的伸縮率改變。第1區域和第5區域為高伸展區域,由於未設有接合部,因此腰圍伸縮部85的伸縮率最高。第4區域為高伸展區域,但設置有接合部,由於接合部使得伸縮率降低,因此腰圍伸縮部85的伸縮率比第1區域及第5區域更低。且,第3區域為低伸展區域,設置有接合部,由於接合部使得伸縮率降低,因此伸縮率比第4區域更低。 The expansion ratio of the waist elasticized portion 85 is changed by the difference in the elongation of the waist elasticized portion and the presence or absence of the joint portion 87. The first region and the fifth region are high stretch regions, and since the joint portion is not provided, the waist stretchable portion 85 has the highest expansion ratio. The fourth region is a high stretch region, but the joint portion is provided, and the expansion ratio is lowered by the joint portion. Therefore, the stretch ratio of the waist stretch portion 85 is lower than that of the first region and the fifth region. Further, the third region is a low stretch region, and the joint portion is provided, and the expansion ratio is lowered by the joint portion, so that the expansion ratio is lower than that of the fourth region.
且,由於第2區域未設有接合部,僅因為腰圍伸縮部的伸長率不同就使得伸縮率改變。具體地說,寬度方向中央(第4區域的寬度方向的範圍)為高伸展區域,伸縮率高。另一方面,寬度方向外側(第3區域和第 5區域的寬度方向的範圍)為低伸展區域,伸縮率低。 Further, since the joint portion is not provided in the second region, the expansion ratio is changed only because the elongation of the waist stretch portion is different. Specifically, the center in the width direction (the range in the width direction of the fourth region) is a high stretch region, and the stretch ratio is high. On the other hand, the width direction outer side (the third area and the The range of the width direction of the 5 region is a low stretch region, and the stretch ratio is low.
接著,說明關於本實施形態的吸收性物品之製造方法的一例。此外,關於本實施形態中未說明的方法,可使用既存的方法。且,以下說明的製造方法為一例,亦可藉由其他製造方法製造。吸收性物品的製造方法至少包含:構成構件形成步驟、構成構件載置步驟、接合部形成步驟、腿圍形成步驟、以及裁切步驟。 Next, an example of a method of producing an absorbent article according to the present embodiment will be described. Further, regarding the method not described in the embodiment, an existing method can be used. Further, the production method described below is an example, and it can also be manufactured by another manufacturing method. The method for producing an absorbent article includes at least a constituent member forming step, a constituent member placing step, a joint portion forming step, a leg circumference forming step, and a cutting step.
構成構件形成步驟中,形成構成吸收性物品的構成構件。具體地說,例如將吸收材料積層而成型為吸收體40或形成黏扣帶90。 In the constituent member forming step, constituent members constituting the absorbent article are formed. Specifically, for example, the absorbent material is laminated to form the absorbent body 40 or to form the fastening tape 90.
構成構件載置步驟係於構成背部薄片的纖維網上,載置:構成腰圍伸縮部85的伸縮性薄片、或構成頂部薄片的纖維網等其他纖維網、防漏薄片、吸收體、腿部伸縮部75等構成用後即棄式紙尿布10的構成構件。構成構件載置步驟係配置構成腰圍伸縮部85的伸縮薄片。利用構成構件載置步驟將構成構件載置,藉此形成用後即棄式紙尿布朝長度方向連續的連續體。 The constituent member placing step is performed on a fiber web constituting the back sheet, and a stretchable sheet constituting the waist elasticized portion 85 or another web such as a web constituting the top sheet, a leak preventing sheet, an absorbent body, and a leg stretch The portion 75 or the like constitutes a constituent member of the disposable disposable diaper 10. In the component mounting step, the stretch sheets constituting the waist stretchable portion 85 are disposed. The constituent members are placed by the constituent member placing step, thereby forming a continuous body in which the disposable disposable diapers are continuous in the longitudinal direction.
此外,作為使腰圍伸縮部85的伸長率改變的方法,例如可舉出以下方法。在將腰圍伸縮部85貼合於背部薄片60a等之前,藉由齒輪使腰圍伸縮部85朝寬度方向延伸。藉由該齒輪延伸時,將欲使伸長率變低的區域(例如,第2區域)的齒輪延伸減弱。將欲使伸長率變高 的區域(例如,第1區域及第3區域)的齒輪延伸加強。齒輪延伸的強弱係藉由變更齒輪的凸部的深度、齒輪的凸部的間距、齒輪延伸的次數,即能調整。加強延伸的區域的伸長率變成較高,減弱延伸的區域的伸長率變成較低。 Moreover, as a method of changing the elongation of the waist elastic-contraction part 85, the following method is mentioned, for example. Before the waist elastic-contraction portion 85 is bonded to the back sheet 60a or the like, the waist elastic-contraction portion 85 is extended in the width direction by the gear. When the gear is extended, the gear extension of the region where the elongation is to be lowered (for example, the second region) is weakened. Will want to make the elongation higher The gear extension of the area (for example, the first area and the third area) is strengthened. The strength of the gear extension can be adjusted by changing the depth of the convex portion of the gear, the pitch of the convex portion of the gear, and the number of times the gear is extended. The elongation of the region where the reinforcement is extended becomes higher, and the elongation of the region where the elongation is weakened becomes lower.
接合部形成步驟係藉由熱密封形成接合部。 The joint forming step forms the joint by heat sealing.
腿圍形成步驟係裁切頂部薄片50、外裝薄片60、以及背部薄片60a。藉此,形成配置在穿用者的腿圍的腿部開口部35。此外,亦可在腿圍形成步驟之後進行接合部形成步驟。 The leg circumference forming step cuts the top sheet 50, the outer sheet 60, and the back sheet 60a. Thereby, the leg opening portion 35 disposed in the leg circumference of the wearer is formed. Further, the joint forming step may be performed after the leg circumference forming step.
裁切步驟係將配置有頂部薄片50、背部薄片60a、吸收體40等的連續體,沿著寬度方向W裁切成一製品的大小。藉此,在前腰圍區域20配置前腰圍伸縮部,並且在後腰圍區域30配置腰圍伸縮部,以製造用後即棄式紙尿布10。 The cutting step is a continuous body in which the top sheet 50, the back sheet 60a, the absorber 40, and the like are disposed, and is cut into a size of the product in the width direction W. Thereby, the front waist elasticized portion is disposed in the front waistline region 20, and the waist elasticized portion is disposed in the rear waistline region 30 to manufacture the disposable disposable diaper 10.
由於藉由第3區域R3的接合部列,將剛性較高的部分沿著長度方向形成,且藉由腰圍伸縮部85使配置有接合部列的區域沿寬度方向收縮,因此沿寬度方向隔著間隔設置有複數個朝長度方向延伸的皺摺。由於形成朝長度方向延伸的皺摺,因此不易形成朝寬度方向延伸的皺摺。若形成朝寬度方向延伸的皺摺,則會形成朝寬度方向延伸的彎曲起點,因此有產生紙尿布的後端緣浮起而造成***物漏出之虞。但是,由於不易形成朝寬度方向延伸的皺摺, 而能抑制紙尿布的後端緣浮起。 Since the portion having the high rigidity is formed along the longitudinal direction by the joint portion row of the third region R3, and the region in which the joint portion row is disposed is contracted in the width direction by the waist elastic portion 85, the width direction is interposed therebetween. The space is provided with a plurality of wrinkles extending in the longitudinal direction. Since the wrinkles extending in the longitudinal direction are formed, it is difficult to form wrinkles extending in the width direction. When the wrinkles extending in the width direction are formed, a bending starting point extending in the width direction is formed, so that the rear end edge of the disposable diaper floats to cause leakage of excrement. However, since it is difficult to form wrinkles extending in the width direction, The back edge of the disposable diaper can be suppressed from floating.
且,由於形成朝長度方向延伸的皺摺,因此沿寬度方向隔著間隔形成複數個彎曲起點,而容易沿著腰圍的圓弧配置。且,雖然因為朝長度方向延伸的皺摺形成凹凸,但可藉由腰圍伸縮部85使凹凸貼合於身體,因此未形成凹凸造成的間隙,而能抑制穿用者背側的漏出。且,由於在用後即棄式紙尿布的後端緣配置有腰圍伸縮部,能提升用後即棄式紙尿布的後端緣的剛性,而能防止用後即棄式紙尿布的後端緣意外地捲起。 Further, since the wrinkles extending in the longitudinal direction are formed, a plurality of bending starting points are formed at intervals in the width direction, and are easily arranged along the circular arc of the waist circumference. Further, since the unevenness is formed by the wrinkles extending in the longitudinal direction, the waist-concave expansion-contraction portion 85 can be attached to the body by the waist-contracting portion 85. Therefore, a gap due to the unevenness is not formed, and leakage of the wearer's back side can be suppressed. Moreover, since the waist elasticized portion is disposed at the rear end edge of the disposable disposable diaper, the rigidity of the rear end edge of the disposable disposable diaper can be improved, and the rear end of the disposable disposable diaper can be prevented. The edge rolled up unexpectedly.
位於吸收芯40a的寬度方向外側的第1區域R1,係配置在接觸於穿用者的脇部的腰骨之位置。由於第1區域R1未設置接合部列而能維持腰圍伸縮部的伸縮力,相較於設置有接合部列的第3區域R3,其伸縮力高。利用第1區域R1強力地貼合於穿用者的協部的腰骨,藉此提升腰圍的貼合性。能減少身體和用後即棄式紙尿布之間的縫隙,抑制***物的漏出。 The first region R1 located on the outer side in the width direction of the absorbent core 40a is disposed at a position contacting the waist bone of the wearer's flank. Since the first region R1 is not provided with the joint portion row, the expansion and contraction force of the waist stretchable portion can be maintained, and the stretchability is higher than that of the third region R3 in which the joint portion row is provided. The first region R1 is strongly bonded to the waist bone of the wearer's co-part, thereby improving the fit of the waist. It can reduce the gap between the body and the disposable disposable diaper, and suppress the leakage of excrement.
由於第2區域R2未設置接合部87而能維持腰圍伸縮部85的伸縮力,其伸縮力比設置有接合部列的第3區域R3更高。第2區域R2較容易伸縮,以第2區域R2吸收來自吸收芯40a側的變形,能抑制吸收芯40a的變形傳遞至第3區域R3或用後即棄式紙尿布的後端緣。因此,能維持用後即棄式紙尿布的後端緣的貼合性。 Since the joint portion 87 is not provided in the second region R2, the expansion and contraction force of the waist stretchable portion 85 can be maintained, and the expansion and contraction force is higher than the third region R3 in which the joint portion row is provided. The second region R2 is more easily stretched and contracted, and the deformation from the side of the absorbent core 40a is absorbed by the second region R2, and the deformation of the absorbent core 40a can be suppressed from being transmitted to the third region R3 or the trailing edge of the disposable disposable diaper. Therefore, the adhesion of the trailing edge of the disposable disposable diaper can be maintained.
接合部列87L的後端緣配置在用後即棄式紙尿布的後端緣為佳。由於朝長度方向延伸的皺摺到達用後 即棄式紙尿布的後端緣,使得用後即棄式紙尿布的後端緣或其附近不易形成朝寬度方向延伸的折曲起點。因此,能防止因為朝寬度方向延伸的折曲起點使得用後即棄式紙尿布的後端緣浮起。 It is preferable that the rear end edge of the joint portion row 87L is disposed at the rear end edge of the disposable disposable diaper. Since the wrinkles extending in the length direction reach after use The rear end edge of the disposable diaper makes it difficult to form a bending starting point extending in the width direction at or near the rear end edge of the disposable disposable diaper. Therefore, it is possible to prevent the rear end edge of the disposable disposable diaper from floating due to the origin of the bending extending in the width direction.
第2區域R2的至少一部分配置在比吸收芯40a更後方為佳。第2區域R2的至少一部分配置在第3區域R3和吸收體之間。位於吸收芯40a後方的區域不會和吸收體一起變形,因而難以直接傳遞吸收體的變形。藉由第2區域R2吸收來自吸收芯40a側的變形,能有效地抑制吸收芯40a的變形傳遞至第3區域R3。 It is preferable that at least a part of the second region R2 is disposed later than the absorbent core 40a. At least a part of the second region R2 is disposed between the third region R3 and the absorber. The region located behind the absorbent core 40a is not deformed together with the absorbent body, so that it is difficult to directly transmit the deformation of the absorbent body. The deformation from the side of the absorbent core 40a is absorbed by the second region R2, and the deformation of the absorbent core 40a can be effectively suppressed from being transmitted to the third region R3.
藉由接合部而與腰圍伸縮部接合的薄片材,較佳為包含:位於腰圍伸縮部的肌膚對向面側的肌膚面薄片(頂部薄片50、側翼70、以及背部薄片60a)、及位於腰圍伸縮部的非肌膚對向面側的非肌膚面薄片(外裝薄片60)。肌膚面薄片、腰圍伸縮部、以及非肌膚面薄片,係透過接合部接合。能抑制在肌膚面薄片和非肌膚面薄片的兩方形成接合部列造成的皺摺使得肌膚面薄片在紙尿布的後端緣浮起,或非肌膚面薄片在紙尿布的後端緣浮起。且,藉由具有肌膚面薄片,能提升與嬰幼兒的肌膚接觸的面之肌膚觸感。 The sheet material joined to the waist stretchable portion by the joint portion preferably includes a skin sheet (the top sheet 50, the side flaps 70, and the back sheet 60a) on the skin facing surface side of the waist stretch unit, and is located at the waist circumference. The non-skin surface sheet (outer sheet 60) on the non-skin facing side of the stretchable portion. The skin surface sheet, the waist stretch portion, and the non-skin sheet are joined through the joint portion. It is possible to suppress the wrinkles caused by the formation of the joint portion on both the skin surface sheet and the non-skin sheet, so that the skin sheet flakes on the rear end edge of the disposable diaper, or the non-skin sheet flakes on the rear end edge of the disposable diaper. . Moreover, by having a thin surface of the skin, it is possible to enhance the touch of the skin in contact with the skin of the infant.
第1區域R1配置在從腿部伸縮部朝長度方向延伸的區域為佳。製造用後即棄式紙尿布時,使構成腿部伸縮部的彈性構件以連續狀態朝製品長度方向伸展,將伸展狀態的彈性構件接合於纖維網(背部薄片、外裝薄片 等),於製造用後即棄式紙尿布沿長度方向連續的連續體之後,按照每個製品長度將連續體沿著製品寬度方向進行裁切。根據該製法,藉由裁切連續體,使處於伸展狀態的彈性構件沿製品長度方向收縮,只留下接合在腿圍開口部附近的部分。這種製造方法中,在從腿部伸縮部朝長度方向延伸的區域,製造時配置腿部伸縮部,但製品狀態時未配置腿部伸縮部,挾持腿部伸縮部的纖維網彼此未被接合。 It is preferable that the first region R1 is disposed in a region extending from the leg expansion and contraction portion in the longitudinal direction. When the disposable diaper is manufactured, the elastic member constituting the leg stretch portion is stretched in the continuous state toward the longitudinal direction of the product, and the stretched elastic member is joined to the web (back sheet, outer sheet) Then, after the disposable diapers of the disposable paper diapers are successively continuous in the longitudinal direction, the continuum is cut along the width direction of the product for each product length. According to this manufacturing method, by cutting the continuous body, the elastic member in the stretched state is contracted in the longitudinal direction of the product, leaving only the portion joined to the vicinity of the leg opening portion. In the manufacturing method, the leg stretchable portion is disposed in the region extending from the leg stretch portion in the longitudinal direction, but the leg stretch portion is not disposed in the product state, and the webs holding the leg stretch portion are not joined to each other. .
由於在從腿部伸縮部朝長度方向延伸的區域配置有伸縮性較高的第1區域R1(由於不具有接合部),因此肌膚面薄片和非肌膚面薄片未接合的區域貼合於身體,而能抑制該區域的漏出或來自吸收芯的SAP溢出。 Since the first region R1 having high stretchability is disposed in the region extending from the leg stretch portion in the longitudinal direction (the joint portion is not provided), the skin sheet and the non-skin sheet are not joined to the body. It is possible to suppress leakage of the area or SAP overflow from the absorbent core.
第5區域R5及第4區域R4位於比吸收芯40a的外側緣更靠寬度方向的內側為佳。從腰圍伸縮部85的外側緣朝向寬度方向內側,配置:不具有接合部列的第1區域R1、具有接合部列的第3區域R3、不具有接合部列的第5區域R5、以及具有接合部列的第4區域R4。由於交替地配置有伸縮率高的區域和伸縮率低的區域,因此能抑制過於束縛穿用者並提升貼合性。 The fifth region R5 and the fourth region R4 are preferably located on the inner side in the width direction of the outer edge of the absorbent core 40a. The first region R1 having no joint portion, the third region R3 having the joint portion row, the fifth region R5 having no joint portion row, and the joint are disposed from the outer edge of the waist stretchable portion 85 toward the inner side in the width direction. The fourth region R4 of the column. Since the region having a high expansion ratio and the region having a low expansion ratio are alternately arranged, it is possible to suppress the wearer who is too restrained and improve the fit.
更詳細地說,在用後即棄式紙尿布裝設時能提升貼合性。裝設用後即棄式紙尿布時,於用後即棄式紙尿布展開的狀態,將穿用者的身體放置在用後即棄式紙尿布的後腰圍區域。此時,穿用者的身體被放置成覆蓋吸收 芯40a的全寬度。裝設者係於穿用者的身體放置在吸收芯40a的全寬度之狀態,拉開黏扣帶且固定於前腰圍區域。此時,位於比吸收芯40a更靠寬度方向的外側的第1區域R1被朝寬度方向的外側拉開、伸展。另一方面,位於比第1區域R1更靠寬度方向的內側的第4區域R4及第5區域R5係位於比吸收芯40a的外側緣更靠寬度方向內側,由於被施加穿用者的體壓,故幾乎不朝寬度方向伸展。第3區域R3的比吸收芯40a的外側緣更靠寬度方向內側的部分不伸展,而是比吸收芯40a的外側緣更靠寬度方向外側的部分伸展。因此,裝設用後即棄式紙尿布且拉起穿用者之前的狀態的腰圍伸縮部,係第1區域R1及第3區域R3的一部分伸展,第3區域R3的其他部分、第4區域R4及第5區域R5幾乎不伸展。 In more detail, the fit can be improved when the disposable diaper is installed. When the disposable diaper is installed, the wearer's body is placed in the rear waist region of the disposable diaper in a state where the disposable diaper is unfolded after use. At this point, the wearer's body is placed to cover the absorption The full width of the core 40a. The installer attaches the wearer's body to the full width of the absorbent core 40a, pulls the adhesive strip and fixes it to the front waistline area. At this time, the first region R1 located on the outer side in the width direction of the absorbent core 40a is pulled outward and extended in the width direction. On the other hand, the fourth region R4 and the fifth region R5 located on the inner side in the width direction of the first region R1 are located on the inner side in the width direction of the outer edge of the absorbent core 40a, and the body pressure of the wearer is applied. Therefore, it hardly stretches in the width direction. The portion of the third region R3 that is wider than the outer edge of the absorbent core 40a does not extend, but extends beyond the outer edge of the absorbent core 40a in the width direction. Therefore, the waist-contracting portion of the disposable diaper and the state before the wearer is attached, and the first region R1 and the third region R3 are partially extended, and the other portion of the third region R3 and the fourth region are stretched. R4 and the fifth region R5 hardly stretch.
若裝設用後即棄式紙尿布後拉起穿用者,則被施加在吸收芯40a的體壓減少。因此,第3區域R3的其他部分、第4區域R4及第5區域R5相較於拉起穿用者前的狀態,變得容易伸縮。此時,由於腰圍伸縮部的第1區域R1已經伸展,且第4區域R4比第5區域R5更容易伸展,因此第4區域R4被第5區域R5拉伸而伸展。其結果,拉起穿用者後的狀態的腰圍伸縮部的第4區域R4係以弱的力貼合於穿用者的身體。且,同樣地第3區域R3也以弱的力貼合於穿用者的身體。由於設置有伸縮率較高的區域和伸縮率較低的區域,而能抑制過於束縛穿用者並且提升貼合性。 If the disposable diaper is used after the disposable diaper is installed, the body pressure applied to the absorbent core 40a is reduced. Therefore, the other portion of the third region R3, the fourth region R4, and the fifth region R5 are easily stretched and contracted compared to the state before the wearer is pulled up. At this time, since the first region R1 of the waist elasticized portion has been stretched and the fourth region R4 is more easily stretched than the fifth region R5, the fourth region R4 is stretched and stretched by the fifth region R5. As a result, the fourth region R4 of the waist elasticized portion in a state in which the wearer is pulled up is attached to the wearer's body with a weak force. Further, similarly, the third region R3 is also attached to the wearer's body with a weak force. Since the region having a high stretch ratio and the region having a low stretch ratio are provided, it is possible to suppress the wearer who is too restrained and improve the fit.
第2區域R2係橫跨用後即棄式紙尿布的寬度方向的中心而配置為佳。穿用者的背脊的中心配置有背骨,比左右的部位更朝腹側凹陷。該凹陷部位(Michael菱形)為薦骨部分的凹陷,在該凹陷部位配置第2區域R2。在穿用者的凹陷部位配置藉由第2區域R2收縮的部分。因此,能抑制穿用者的背脊的中心和用後即棄式紙尿布之間產生間隙,更確實地防止來自背側的凹陷部位的漏出。 It is preferable that the second region R2 is disposed across the center of the disposable diaper in the width direction. The center of the wearer's back is provided with a back bone, which is more concave toward the ventral side than the left and right parts. The recessed portion (Michael diamond shape) is a recess of the sacral portion, and the second region R2 is disposed at the recessed portion. A portion that is contracted by the second region R2 is disposed in the recessed portion of the wearer. Therefore, it is possible to suppress the occurrence of a gap between the center of the wearer's ridge and the disposable disposable diaper, and more reliably prevent leakage from the recessed portion on the back side.
第3區域R3的接合部的面密度高於第4區域R4的接合部的面密度為佳。由於第3區域R3的每單位面積的接合部的面積高於第4區域R4的每單位面積的接合部的面積,因此第3區域R3的接合部比第4區域R4被配置的更密。但是,由於第4區域的腰圍伸縮部的伸長率比第3區域的腰圍伸縮部的伸長率更高,因此第4區域R4的腰圍伸縮部的伸縮率比第3區域R3的腰圍伸縮部的伸縮率變得更高。穿用者的薦骨部分在凹陷配置由第4區域收縮的部位。因此,能抑制穿用者的背脊的中心和用後即棄式紙尿布之間產生間隙,確實地防止來自背側的凹陷部位的漏出。 The areal density of the joint portion of the third region R3 is higher than the surface density of the joint portion of the fourth region R4. Since the area of the joint portion per unit area of the third region R3 is higher than the area of the joint portion per unit area of the fourth region R4, the joint portion of the third region R3 is disposed more densely than the fourth region R4. However, since the elongation of the waist elasticized portion of the fourth region is higher than the elongation of the waist elasticized portion of the third region, the expansion ratio of the waist elasticized portion of the fourth region R4 is larger than that of the waist elasticized portion of the third region R3. The rate has become higher. The sacral portion of the wearer is placed in the recessed portion where the fourth region is contracted. Therefore, it is possible to suppress a gap between the center of the wearer's ridge and the disposable disposable diaper, and to reliably prevent leakage from the recessed portion on the back side.
接著,根據圖5說明關於變形例之用後即棄式紙尿布。 Next, a disposable diaper for use in a modification will be described based on Fig. 5 .
圖5係變形例之用後即棄式紙尿布10A的後端緣的放 大俯視圖。此外,在變形例之用後即棄式紙尿布,針對與實施形態的用後即棄式紙尿布同樣的構成,使用相同符號而省略說明。變形例之用後即棄式紙尿布10A具有複數個第3區域R3和複數個第5區域R5。因此,在用後即棄式紙尿布的後端緣,從用後即棄式紙尿布的寬度方向中央朝向外側依序配置:腰圍伸縮部85的伸縮率較低的第4區域R4、伸縮率較高的第5區域R5、伸縮率較低的第3區域R3、伸縮率較高的第5區域R5、伸縮率較低的第3區域R3、以及伸縮率較高的第1區域R1。 Figure 5 is a rear view of the disposable diaper 10A of the modified embodiment. Large top view. In addition, the disposable diaper after the modification is the same as that of the disposable diaper of the embodiment, and the description is omitted. The disposable diaper 10A after the modification has a plurality of third regions R3 and a plurality of fifth regions R5. Therefore, the rear end edge of the disposable disposable diaper is disposed in order from the center in the width direction of the disposable disposable diaper to the outer side: the fourth region R4 in which the stretch ratio of the waist elasticized portion 85 is low, and the expansion ratio The fifth region R5 is high, the third region R3 having a low expansion ratio, the fifth region R5 having a high expansion ratio, the third region R3 having a low expansion ratio, and the first region R1 having a high expansion ratio.
藉由該變形例之用後即棄式紙尿布,亦能在用後即棄式紙尿布的後端緣形成朝長度方向延伸的皺摺,抑制用後即棄式紙尿布的後端緣浮起,維持背側的貼合性。且,由於能藉由腰圍伸縮部使凹凸貼合於身體,因此不形成凹凸造成的間隙,能抑制穿用者的背側的漏出。且,變形例之用後即棄式紙尿布在腿側伸縮部80的彈性構件81的長度方向的延長線上配置有第5區域R5。由於在從彈性構件81朝長度方向延伸的延長線上未配置接合部,因此製造時彈性構件81未被接合部固定,而能於使彈性構件81朝長度方向收縮的狀態配置。 According to the disposable disposable diaper of the modified example, the wrinkle extending in the longitudinal direction can be formed at the rear end edge of the disposable disposable diaper, and the rear end edge of the disposable disposable diaper can be suppressed from floating. From the beginning, maintain the fit on the back side. Further, since the unevenness can be attached to the body by the waist-contracting portion, the gap caused by the unevenness is not formed, and leakage of the back side of the wearer can be suppressed. In the disposable diaper after the modification, the fifth region R5 is disposed on the extension line of the elastic member 81 of the leg side expansion-contraction portion 80 in the longitudinal direction. Since the joint portion is not disposed on the extension line extending from the elastic member 81 in the longitudinal direction, the elastic member 81 is not fixed to the joint portion at the time of manufacture, and can be disposed in a state in which the elastic member 81 is contracted in the longitudinal direction.
