The three-dimensional hemming part 8 is a part of the side sheet 6 standing up to the skin side by the three-dimensional hemming part elastic member 9 which expands and contracts in the longitudinal direction. Excretion is blocked by the three-dimensional hem portion 8.
腿圍彈性構件10,是較寬邊方向的立體摺邊部8的立起起點(將側薄片6接著在頂面薄片3的接著劑(不圖示)的寬邊方向內側端)更被配置在寬邊方向的外側。藉由腿圍彈性構件10,紙尿布1貼合在穿用者的腿圍,而抑制排泄物的漏出。The leg circumference elastic member 10 is a starting point for setting up the three-dimensional hemming portion 8 in the wider side direction (the side sheet 6 is attached to the inner side end in the width side direction of the adhesive (not shown) of the top sheet 3). Outside on the wide side. With the leg circumference elastic member 10, the paper diaper 1 is fitted to the leg circumference of the wearer, and leakage of excretion is suppressed.
作為立體摺邊部用彈性構件9、及腿圍彈性構件10可例示絲線橡膠等的絲狀彈性構件。可是,不限於此,也可為伸縮性薄膜等的薄片狀彈性構件。Examples of the elastic member 9 for the three-dimensional hemming portion and the elastic elastic member 10 for the legs include a thread-like elastic member such as a silk rubber. However, it is not limited to this, and it may be a sheet-like elastic member such as a stretchable film.
又,立體摺邊部用彈性構件9、及腿圍彈性構件10分別具有能在長邊方向產生伸縮性的伸縮部(有效長部分)。立體摺邊部用彈性構件9、及腿圍彈性構件10中,朝長邊方向伸長的狀態下被固定在薄片的部位成為伸縮部。在圖面僅伸縮部表示。In addition, the elastic member 9 for three-dimensional hemming portions and the leg elastic member 10 each have a stretchable portion (effectively long portion) capable of generating stretchability in the longitudinal direction. The elastic member 9 for the three-dimensional hemming part and the leg elastic member 10 are fixed to the sheet in a state of being extended in the longitudinal direction, and become a stretchable part. Only the telescopic part is shown in the drawing.
又,紙尿布1具有從第1腰圍部1A(長邊方向的一方側的腰圍部)朝寬邊方向的兩外側延伸出的一對的黏扣帶7。黏扣帶7具有:帶片基材7A、和鉤材7B。帶片基材7A,是形成寬邊方向長的大致長方形狀。鉤材7B,是例如平面扣具的公構件,並被設在帶片基材7A的肌膚側面。The paper diaper 1 includes a pair of hook-and-loop fasteners 7 extending from the first waistline portion 1A (the waistline portion on one side in the longitudinal direction) to both outer sides in the widthwise direction. The hook and loop tape 7 includes a tape base material 7A and a hook material 7B. The strip base material 7A is formed in a substantially rectangular shape that is long in the width direction. The hook material 7B is a male member of a flat fastener, for example, and is provided on the skin side of the belt base material 7A.
紙尿布1的裝設時、展開狀態的紙尿布1,是邊貼於穿用者邊在長邊方向的大致中央被對折。接著,朝內側翻折第1腰圍部1A的寬邊方向的兩側部。最後,將黏扣帶7的鉤材7B卡止在第2腰圍部1C的非肌膚側面。When the paper diaper 1 is installed, the paper diaper 1 in the unfolded state is folded in half in the approximate center of the longitudinal direction while being attached to the wearer. Next, the both sides of the width direction of the 1st waistline part 1A are turned inward. Finally, the hook material 7B of the hook-and-loop fastener 7 is locked on the non-skin side of the second waistline portion 1C.
又,紙尿布1,是低體重兒用。因此,將紙尿布1朝長邊方向展開且伸長的狀態的紙尿布1的長邊方向的長度(產品長L1)設在175mm~330mm左右即可。詳而言之,是將體重未滿2500g用的產品長L1設在310mm,將體重未滿1500g用的產品長L1設在270mm,將體重未滿1000g用的產品長L1設在230mm左右。The diaper 1 is intended for low-weight children. Therefore, the length (product length L1) of the paper diaper 1 in a state where the paper diaper 1 is stretched and extended in the longitudinal direction (product length L1) may be set to about 175 mm to 330 mm. Specifically, the product length L1 for a person weighing less than 2500 g is set to 310 mm, the product length L1 for a person weighing less than 1500 g is set to 270 mm, and the product length L1 for a person weighing less than 1000 g is set to about 230 mm.
又,紙尿布1的腰的尺寸設在160~295mm左右即可。詳而言之,是將體重未滿2500g用的腰的尺寸設在273.5mm,將體重未滿1500g用的腰的尺寸設在220mm左右即可。腰的尺寸,是將一方的黏扣帶7的寬邊方向的前端對齊另一方的黏扣帶7具有的鉤材7B的寬邊方向的根部側的端部的狀態下,將製品朝寬邊方向伸長到沒有皺紋的狀態的尺寸。The waist size of the paper diaper 1 may be set to about 160 to 295 mm. Specifically, the size of the waist for a person weighing less than 2500 g may be set to about 273.5 mm, and the size of the waist for a person weighing less than 1500 g may be set to about 220 mm. The size of the waist is a state in which the front end of the one side of the hook-and-loop fastener 7 is aligned with the end on the root side of the hook-side member 7B of the other hook-and-loop fastener 7 in the width-wise direction, and the product is directed toward the broad side. The direction is extended to a size without wrinkles.
<<紙尿布1前後倒著裝設>> 圖3A至圖3C,是紙尿布1的裝設狀態的說明圖。低體重兒之中,尤其未滿2500公克被生出的低體重兒,會有希望以在胎內時的姿勢趴著渡過的想法。在胎內時的姿勢,是指如圖3A所示使背部捲成C字狀的同時,如圖3C所示邊使腳成M字開腳,邊將兩膝拉到靠近腹部的位置的狀態。以下,也將這樣的姿勢稱為「彎曲的趴著姿勢」。<<< Paper diaper 1 is installed upside down >> FIGS. 3A to 3C are explanatory diagrams of the installation state of the paper diaper 1. Among the low-weight babies, especially those born under 2,500 grams, there is a desire to spend time lying on their stomachs. The posture in the fetus refers to a state in which the back is rolled into a C shape as shown in FIG. 3A, while the feet are opened in an M shape as shown in FIG. 3C, and both knees are pulled close to the abdomen. . Hereinafter, such a posture is also referred to as a "curved lying posture".
又,會有希望儘量不要碰觸到低體重兒的身體的減少觸碰的想法。In addition, there is a desire to reduce the number of touches as much as possible without touching the body of a low-weight child.
因此,在紙尿布1的更換時,會有不讓低體重兒仰躺,而是使紙尿布1通過趴著的低體重兒的腳之間,對趴著的狀態的低體重兒進行紙尿布1更換的情況。因此,不僅如圖3A所示,以設有黏扣帶7的第1腰圍部1A覆蓋背側的方式被裝設的通常的裝設,有如圖3B所示,以第1腰圍部1A覆蓋腹側方式進行裝設的前後倒著裝設。前後倒著裝設的時候,不需要將手伸入趴著的低體重兒的腹部,進行黏扣帶7的卡止、卸下。Therefore, during the replacement of the diaper 1, the low-weight child is not allowed to lie on his back, but the diaper 1 is passed between the feet of the low-weight child who is lying down, and the low-weight child who is lying down performs the diaper. 1 Replacement case. Therefore, as shown in FIG. 3A, the usual installation is not only installed so that the 1st waistline part 1A provided with the hook-and-loop fastener 7 covers the back side, but as shown in FIG. 3B, the 1st waistline part 1A covers the abdomen Side-by-side installation. When installed backwards and forwards, there is no need to put a hand into the belly of a lying low-weight child to engage and remove the hook-and-loop fastener 7.
又,在紙尿布1設置切開固定有黏扣帶7的第1腰圍部1A的一部分用的切開線11即可。這麼以來,自低體重兒卸下紙尿布1變的容易。Further, the paper diaper 1 may be provided with a cutting line 11 for cutting a part of the first waistline portion 1A to which the hook and loop fastener 7 is fixed. In this way, it is easy to remove the diaper 1 from a low-weight child.
<<低體重兒用的紙尿布1的特徵>> 圖4A及圖4B,是紙尿布1的包裝方法的說明圖。圖4C,是比較例的紙尿布1’的裝設狀態的說明圖。圖5,是吸收性芯2的俯視圖。圖6A及圖6B,是產品長L1的說明圖。圖7A及圖7B,是觀看產品長L2及觀看高度H2的說明圖。圖6A及圖7A,是測量時的紙尿布1的概略立體圖,圖6B及圖7B,是測量時的紙尿布1的概略剖視圖。<<< Characteristics of the paper diaper 1 for low-weight children >> FIG. 4A and FIG. 4B are explanatory diagrams of the packaging method of the paper diaper 1. FIG. Fig. 4C is an explanatory view of an installed state of the paper diaper 1 'of the comparative example. FIG. 5 is a plan view of the absorbent core 2. 6A and 6B are explanatory diagrams of the product length L1. 7A and 7B are explanatory diagrams of the viewing product length L2 and the viewing height H2. 6A and 7A are schematic perspective views of the paper diaper 1 during measurement, and FIGS. 6B and 7B are schematic cross-sectional views of the paper diaper 1 during measurement.
紙尿布1在包裝狀態下藉由沿著寬邊方向的折線FL被對折。具體而言,如圖4A所示,將紙尿布1的寬邊方向的兩側部朝寬邊方向的內側折了之後,如圖4B所示,在藉由紙尿布1的長邊方向中央的折線FL被對折的狀態下被包裝。The paper diaper 1 is folded in half in the packed state by the fold line FL along the wide side direction. Specifically, as shown in FIG. 4A, after both sides of the wide diaper direction of the paper diaper 1 are folded inward in the wide wise direction, as shown in FIG. 4B, The folding line FL is packed in a state of being folded in half.
於此,定義紙尿布1的「產品長L1」、「觀看產品長L2」、「觀看高度H2」。 「產品長L1」,是指將被對折的紙尿布1朝長邊方向展開且伸長的狀態的紙尿布1的長邊方向的長度L1(參照圖1、圖6A、圖6B)。 「觀看產品長L2」,是指將紙尿布1朝長邊方向展開且伸長之後,將紙尿布1的肌膚側面朝下,放置在台的上面的自然狀態下的紙尿布1的長邊方向的長度L2(參照圖7A、圖7B)。 「觀看高度H2」,是指在上述的自然狀態(圖7A、圖7B)下和台的上面垂直的方向的紙尿布1的高度。Here, "product length L1", "view product length L2", and "view height H2" of the diaper 1 are defined. "Product length L1" refers to the length L1 of the longitudinal direction of the paper diaper 1 in a state where the folded paper diaper 1 is extended in the longitudinal direction (see Figs. 1, 6A, and 6B). "Looking product length L2" refers to the long side direction of the natural diaper 1 after the paper diaper 1 is unfolded and stretched in the long side direction, and the skin side of the paper diaper 1 is placed downward on the table. Length L2 (see FIGS. 7A and 7B). "Viewing height H2" refers to the height of the paper diaper 1 in a direction perpendicular to the upper surface of the table under the above-mentioned natural state (Figs. 7A and 7B).
將紙尿布1朝長邊方向展開後的狀態,是指包裝時的對折打開的狀態。將紙尿布1朝長邊方向伸長的狀態,是指將紙尿布1朝長邊方向伸長到紙尿布1所產生的皺紋實質上不能視認的程度的狀態。詳而言之,是將構成紙尿布1的各構件(例如,側薄片6等)的長邊方向的尺寸伸長到與其構件單體的長邊方向的尺寸一致或接近這個尺寸為止的長度,將紙尿布1伸長的狀態。The state in which the paper diaper 1 is unfolded in the longitudinal direction refers to a state in which the paper diaper 1 is folded open at the time of packaging. The state in which the paper diaper 1 is extended in the longitudinal direction means a state in which the paper diaper 1 is extended in the longitudinal direction to such an extent that the wrinkles generated by the paper diaper 1 are substantially invisible. Specifically, the length of each member (for example, the side sheet 6 and the like) constituting the paper diaper 1 is extended to a length that is equal to or close to the size of the longitudinal direction of the member alone, and The diaper 1 is in an extended state.
就產品長L1、觀看產品長L2、觀看高度H2的測量方法來說,可例示以下的方法。首先,從包裝袋取出被對折的紙尿布1。然後,在紙尿布1的長邊方向的兩端1a、1b的寬邊方向的中心分別標示印記M1、M2。As a measurement method of the product length L1, the viewing product length L2, and the viewing height H2, the following methods can be exemplified. First, the folded paper diaper 1 is taken out from the packaging bag. And the center of the width direction of the both ends 1a and 1b of the longitudinal direction of the paper diaper 1 is marked with the marks M1 and M2, respectively.
接著,將紙尿布1朝長邊方向展開且伸長後的狀態下,固定在試驗台30的上面30a(水平面)(參照圖6A)。此時,將紙尿布1的非肌膚側面1c朝上,將紙尿布1的肌膚側面1d朝下(和試驗台30對置)。又,讓紙尿布1的長邊方向和試驗台30的上面30a的X方向一致。在此狀態下,測量紙尿布1的長邊方向的一端1a(印記M1)到另一端1b(印記M2)的X方向的長度(紙尿布1的長邊方向的長度)。將所測量的長度作為「產品長L1」。Next, the paper diaper 1 is extended and extended in the longitudinal direction, and is fixed to the upper surface 30a (horizontal surface) of the test stand 30 (see FIG. 6A). At this time, the non-skin side surface 1c of the paper diaper 1 faces upward, and the skin side 1d of the paper diaper 1 faces downward (opposing the test stand 30). The longitudinal direction of the paper diaper 1 is aligned with the X direction of the upper surface 30 a of the test stand 30. In this state, the length in the X direction (the length in the longitudinal direction of the paper diaper 1) of the one end 1a (imprint M1) to the other end 1b (imprint M2) in the longitudinal direction of the paper diaper 1 is measured. Let the measured length be "product length L1".
接著,從上述的狀態解放長邊方向的伸長狀態,使紙尿布1成為自然狀態(參照圖7A)。紙尿布1具有立體摺邊部用彈性構件9、及腿圍彈性構件10。又,紙尿布1具有包裝時的折線FL。因此,紙尿布1的自然狀態下,兩彈性構件9、10收縮,紙尿布1的長邊方向的中央部像山一樣地隆起。在此狀態下,測量紙尿布1的長邊方向的一端1a(印記M1)到另一端1b(印記M2)的X方向的長度(紙尿布1的長邊方向的長度)。將所測量的長度作為「觀看產品長L2」。又,在和試驗台30的上面30a垂直的方向,將上面30a到紙尿布1的頂點1e的長度設為「觀看高度H2」。Next, the state of elongation in the longitudinal direction is released from the state described above, and the paper diaper 1 is brought into a natural state (see FIG. 7A). The paper diaper 1 has the elastic member 9 for three-dimensional hems, and the leg periphery elastic member 10. Moreover, the paper diaper 1 has the folding line FL at the time of packaging. Therefore, in the natural state of the paper diaper 1, the two elastic members 9, 10 are contracted, and the central portion in the longitudinal direction of the paper diaper 1 is raised like a mountain. In this state, the length in the X direction (the length in the longitudinal direction of the paper diaper 1) of the one end 1a (imprint M1) to the other end 1b (imprint M2) in the longitudinal direction of the paper diaper 1 is measured. The measured length is referred to as "view product length L2". Moreover, the length from the upper surface 30a to the vertex 1e of the paper diaper 1 in the direction orthogonal to the upper surface 30a of the test stand 30 was set as "viewing height H2."
和產品長L1相比觀看產品長L2小,所謂觀看產品長L2除以產品長L1的值(L2/L1)變小,是指紙尿布1的長邊方向的中央部的山的高度(觀看高度H2)變高。亦即,指紙尿布1在自然狀態容易對折的情況。The product length L2 is smaller than the product length L1. The value of the product length L2 divided by the product length L1 (L2 / L1) becomes smaller, which refers to the height of the mountain in the center of the long side of the diaper 1 (viewing). The height H2) becomes higher. That is, it refers to a case where the diaper 1 is easily folded in half in a natural state.
相反的,所謂觀看產品長L2除以產品長L1的值(L2/L1)變大,是指紙尿布1的長邊方向的中央部的山的高度(觀看高度H2)變低,而容易維持將紙尿布1朝長邊方向展開的狀態。On the contrary, the value of the product length L2 divided by the product length L1 (L2 / L1) becomes larger, which means that the height of the mountain (viewing height H2) in the central part of the longitudinal direction of the paper diaper 1 becomes low, and it is easy to maintain A state where the paper diaper 1 is extended in the longitudinal direction.
於此,針對本實施形態的紙尿布1的吸收性芯2的形狀進行說明。如圖5所示,吸收性芯2在長邊方向的中央部具有較端部更寬度窄的狹窄部2A。再者,長邊方向的吸收性芯2的中央CL(在長邊方向將吸收性芯2對分的中央CL)的寬度W1,是15mm以上45mm以下。Here, the shape of the absorbent core 2 of the paper diaper 1 of this embodiment is demonstrated. As shown in FIG. 5, the absorptive core 2 has the narrow part 2A narrower than the end part in the center part of a longitudinal direction. The width W1 of the center CL of the absorptive core 2 in the longitudinal direction (the center CL that bisects the absorptive core 2 in the longitudinal direction) is 15 mm or more and 45 mm or less.
此外,本實施形態的吸收性芯2的情況,在長邊方向的中央CL配置有一對的缺口部22b(詳細為後述)。因此,一對的缺口部22b的頂點間的寬邊方向的長度W1成為15mm以上45mm以下。再者,缺口部22b附近的吸收性芯2的寬度W2也成為15mm以上45mm以下。In the case of the absorptive core 2 of the present embodiment, a pair of cutout portions 22b are arranged at the center CL in the longitudinal direction (the details will be described later). Therefore, the length W1 in the width direction between the vertexes of the pair of notches 22b is 15 mm or more and 45 mm or less. In addition, the width W2 of the absorptive core 2 near the notch portion 22b is also 15 mm or more and 45 mm or less.
將吸收性芯2的長邊方向的中央CL的寬度W1(W2)設在15mm以上,可確保吸收性芯2的吸收能力,並可防止漏尿。另一方面,在吸收性芯2設置狹窄部2A,將吸收性芯2的長邊方向的中央CL的寬度W1(W2)設在45mm以下,而使抵接在低體重兒的胯間部的吸收性芯2的寬度變窄。因此,低體重兒容易活動腳。又,當低體重兒闔著腳的時候,可抑制剛性高的吸收性芯2壓迫低體重兒的肌膚的情況。Setting the width W1 (W2) of the center CL of the absorptive core 2 in the longitudinal direction to 15 mm or more can ensure the absorptive capacity of the absorptive core 2 and prevent urine leakage. On the other hand, a narrow portion 2A is provided on the absorbent core 2 and the width W1 (W2) of the center CL in the longitudinal direction of the absorbent core 2 is set to 45 mm or less so as to be in contact with the intercondylar portion of a low-weight child. The width of the absorbent core 2 is narrowed. Therefore, low-weight children tend to move their feet. In addition, when the low-weight child stands on his or her feet, it is possible to suppress the skin of the low-weight child from being pressed by the highly rigid absorbent core 2.
可是,若在吸收性芯2設置狹窄部2A,如圖1所示,使寬邊方向中的吸收性芯2的側端到紙尿布1的側端的腿圍的薄片部分(背面薄片5、側薄片6等)的長度W3變長。因為腿圍的薄片部分的長度W3長,而可確保立體摺邊部8的高度。可是,若以腿圍的薄片部分接觸低體重兒的腳的程度寬鬆裝設紙尿布1,則用低體重兒的腳夾著腿圍的薄片部分時,會有吸收性芯2從低體重兒的胯間部、臀部浮起的顧慮。However, if a narrow portion 2A is provided in the absorbent core 2, as shown in FIG. 1, the sheet portion (back sheet 5, side) of the leg periphery of the absorbent core 2 in the wide side direction to the side end of the paper diaper 1 The length W3 of the sheet 6 and the like becomes longer. Since the length W3 of the sheet portion around the legs is long, the height of the three-dimensional folded portion 8 can be secured. However, if the paper diaper 1 is loosely installed so that the thin portion of the leg circumference touches the foot of the low-weight child, the absorbent core 2 will move from the low-weight child when the thin portion of the leg circumference is sandwiched between the low-weight foot Concerns floating around the hips and hips.
因此,增大前述的觀看產品長L2除以產品長L1的值(L2/L1)即可。假使,縮小觀看產品長L2除以產品長L1的值(L2/L1),倘若容易在包裝時的折線FL將紙尿布1對折,則容易在吸收性芯2從低體重兒浮起的狀態裝設紙尿布。Therefore, it is sufficient to increase the value (L2 / L1) of the aforementioned product length L2 divided by the product length L1. If the value of the product length L2 divided by the product length L1 (L2 / L1) is reduced, if it is easy to fold the paper diaper 1 in half at the folding line FL at the time of packaging, it is easy to install the absorbent core 2 in a state where it is floating from a low birth weight Set up paper diapers.
因為,將紙尿布裝設在低體重兒的護士等,將紙尿布鋪設在低體重兒的下面、或使紙尿布通過趴著的低體重兒的腳之間,放開手之後,會有紙尿布瞬間被對折起來的情況。這麼一來,不易讓吸收性芯2順著低體重兒的胯間部、臀部,而如圖4C所示以包裝時的折線FL對折紙尿布1’的狀態下被裝設。亦即,吸收性芯2從低體重兒浮起的狀態下被裝設。This is because nurses who place paper diapers on low-weight infants lay paper diapers under the low-weight babies or pass the paper diapers between the feet of the low-weight babies lying on their backs. The case where the diaper is momentarily folded in half. As a result, the absorbent core 2 cannot easily be installed along the intercondylar portion and hips of a low-weight child, as shown in FIG. 4C, with the folding line FL folded toward the paper diaper 1 'during packaging. That is, the absorptive core 2 is installed in the state which floated from a low-weight child.
表1,是使觀看產品長L2除以產品長L1的値(L2/L1)變化,評價吸收性芯2對低體重兒的貼合性的結果。Table 1 shows the results of evaluating the fit of the absorbent core 2 to low-weight children by changing the product length L2 divided by the product length L1 (L2 / L1).
試作5種類的樣本1~5。測量各樣本1~5的產品長L1及觀看產品長L2,算出觀看產品長L2除以產品長L1的値(L2/L1)。又,被試驗者對於模仿低體重兒的人偶實際安裝各樣本1~5,進行貼合性的評價。Try 5 types of samples 1-5. The product length L1 and the viewing product length L2 of each of the samples 1 to 5 were measured, and 値 (L2 / L1) of the viewing product length L2 divided by the product length L1 was calculated. In addition, the subjects actually mounted each of the samples 1 to 5 on a puppet imitating a low-weight child and evaluated the fit.
樣本1~5的規格,是接下來所述。立體摺邊部用彈性構件9的伸長倍率,是樣本1為1.99倍,樣本2為1.85倍,樣本3為1.55倍,樣本4為1.46倍,將樣本5作成不具立體摺邊部用彈性構件9者。此外,伸長倍率,是將彈性構件的自然長設為1時的伸長幅度,來顯示彈性構件的伸縮的強度。又,長邊方向的吸收性芯的剛性,是樣本1~3高(硬),樣本4~5低(柔軟)者。又,作成樣本1~4具有腿圍彈性構件10者,樣本5不具腿圍彈性構件10者。產品長L1,是樣本1~3為240mm,樣本4~5為230mm。The specifications of samples 1 to 5 are described below. The elongation magnification of the elastic member 9 for the three-dimensional hemming part is 1.99 times that of the sample 1, 1.85 times for the sample 2, 1.55 times for the sample 3, and 1.46 times for the sample 4. By. In addition, the elongation factor is the elongation width when the natural length of the elastic member is set to 1, and the strength of expansion and contraction of the elastic member is displayed. The rigidity of the absorptive core in the long-side direction is one in which samples 1 to 3 are high (hard) and samples 4 to 5 are low (soft). In addition, samples 1 to 4 were prepared with leg circumference elastic members 10, and samples 5 were not provided with leg circumference elastic members 10. The product length L1 is 240mm for samples 1 to 3 and 230mm for samples 4 to 5.
貼合性的評價,是被試驗者利用目視觀察裝設各樣本1~5的人偶,或從樣本上碰觸人偶的臀部來進行。被試驗者,是將感覺到「吸收性芯2從人偶浮起小,且貼合性佳」的樣本評價為「○」,將感覺到「吸收性芯2從人偶浮起大,且貼合性不佳」的樣本評價為「×」。The applicability was evaluated by visually observing the puppets installed with each of the samples 1 to 5, or touching the puppet's hips from the samples. The test subject evaluated the sample that felt "the absorptive core 2 floated from the puppet small and had good fit" as "○", and felt that "the absorptive core 2 floated large from the puppet, and The sample with poor adhesion was evaluated as "×".
從表1的結果可知,在觀看產品長L2除以產品長L1的値為0.52及0.69的樣本1~2,其吸收性芯2對低體重兒的貼合性不佳。另一方面,可知在觀看產品長L2除以產品長L1的値為0.72、0.79及1的樣本3~5,其吸收性芯2對低體重兒的貼合性佳。From the results in Table 1, it can be seen that when samples 1 and 2 whose product length L2 divided by product length L1 is 0.52 and 0.69 are observed, the absorptive core 2 has poor adhesion to low-weight children. On the other hand, it can be seen that when samples 3 to 5 whose product length L2 divided by product length L1 is 0.72, 0.79, and 1 are observed, the absorptive core 2 has good adhesion to low-weight children.
於此,在低體重兒用的本實施形態的紙尿布1,將觀看產品長L2除以產品長L1的值設在0.7以上1以下(0.7≦L2/L1≦1)。Here, in the paper diaper 1 of this embodiment for low-weight children, the value of the product length L2 divided by the product length L1 is set to 0.7 or more and 1 or less (0.7 ≦ L2 / L1 ≦ 1).
這樣一來,不易以包裝時的折線FL將紙尿布1對折,而容易維持將紙尿布1朝長邊方向展開的狀態。因此,紙尿布1的裝設時,護理師等將紙尿布1鋪設在低體重兒之下,使紙尿布1通過趴著的低體重兒的腳之間,放開手之後,容易成為紙尿布1朝長邊方向展開的狀態。因此,邊讓吸收性芯2沿著低體重兒的胯間部、臀部,而容易裝設紙尿布1。因此,即使腿圍的薄片部分的長度W3(參照圖1)長,也可抑制吸收性芯2從低體重兒的胯間部、臀部的浮起,可讓吸收性芯2對低體重兒的貼合性提升。This makes it difficult to fold the paper diaper 1 in half with the fold line FL at the time of packaging, and it is easy to maintain the state where the paper diaper 1 is unfolded in the longitudinal direction. Therefore, when the paper diaper 1 is installed, a caregiver or the like lays the paper diaper 1 under a low-weight child, passes the paper diaper 1 between the feet of a lying low-weight child, and releases the hand, which is likely to become a paper diaper. 1The state of spreading toward the long side. Therefore, it is easy to install the paper diaper 1 with the absorptive core 2 along the intercondylar part and the buttocks of a low-weight child. Therefore, even if the length W3 (refer to FIG. 1) of the sheet portion of the leg circumference is long, it is possible to suppress the absorptive core 2 from floating from the intercondylar portion and the buttocks of a low-weight child, and to allow the absorbent core 2 to prevent Improved fit.
如此抑制吸收性芯2的浮起,排泄尿不會傳到低體重兒的肌膚可在吸收性芯2被吸收。因此,可抑制因排泄尿刺激低體重兒的肌膚的情況。In this way, the floating of the absorbent core 2 is suppressed, and the skin which does not pass urine to a low-weight child can be absorbed in the absorbent core 2. Therefore, it is possible to suppress the irritation of the skin of low-weight children due to excretion of urine.
又,低體重兒特有的彎曲的趴著姿勢,是在從紙尿布1的外面所推測的低體重兒的臀部的位置,對齊低體重兒的腳的腳根的位置。因此,如圖4C所示,吸收性芯2從低體重兒的臀部浮起的話,低體重兒的腳的拉起變的不足。因此,可抑制吸收性芯2的浮起,可將低體重兒的腳拉起到適當的位置。In addition, the curved lying position peculiar to the low-weight child is aligned with the position of the base of the foot of the low-weight child at the position of the buttocks of the low-weight child estimated from the outside of the diaper 1. Therefore, as shown in FIG. 4C, when the absorptive core 2 floats from the buttocks of the low-weight child, the lifting of the foot of the low-weight child becomes insufficient. Therefore, the lifting of the absorbent core 2 can be suppressed, and the feet of a low-weight child can be pulled up to a proper position.
又,因為容易維持紙尿布1朝長邊方向展開的狀態,在紙尿布1的裝設時,在趴著的低體重兒的腳之間,也可順暢地通過紙尿布1,而裝設性佳。又,護理師等將紙尿布1鋪設在低體重兒之下、或使紙尿布1通過趴著的低體重兒的腳之間,放開手之後,紙尿布1不易瞬間被對折。因此,可防止對折的紙尿布1刺激低體重兒的肌膚的情況。In addition, because it is easy to maintain the state of the diaper 1 deployed in the longitudinal direction, the diaper 1 can be smoothly passed through the diaper 1 between the feet of a low-lying child who is lying down during the installation of the diaper 1. good. In addition, a nurse or the like lays the diaper 1 under a low-weight child, or passes the diaper 1 between the feet of a lying low-weight child. After releasing the hand, the diaper 1 is not easily folded in half instantly. Therefore, it is possible to prevent the folded paper diaper 1 from irritating the skin of a low-weight child.
表2,是讓觀看高度H2變化,評價吸收性芯2對低體重兒的貼合性的結果。試作4種類的樣本6~9,測量觀看高度H2。然後,被試驗者對於模仿低體重兒的人偶實際安裝各樣本6~9,進行貼合性的評價。Table 2 shows the results of evaluating the fit of the absorbent core 2 to low-weight infants by changing the viewing height H2. Four types of samples 6 to 9 were made, and the viewing height H2 was measured. Then, the subjects actually mounted each sample 6 to 9 on a puppet imitating a low-weight child, and evaluated the fit.
樣本6~9的規格,是接下來所述。立體摺邊部用彈性構件9的伸長倍率,是樣本6為1.99倍,樣本7為2.17倍,樣本8為2.10倍,樣本9為1.46倍。又,長邊方向的吸收性芯2的剛性,是樣本6~7高(硬),樣本8~9低(柔軟)者。產品長L1,是樣本6、8為240mm,樣本7為175mm,樣本9為230mm。又,作成全樣本6~9具有腿圍彈性構件10者。The specifications of samples 6 to 9 are described below. The elongation ratio of the elastic member 9 for the three-dimensional hemming part is 1.99 times that of the sample 6, 2.17 times that of the sample 7, 2.10 times that of the sample 8, and 1.46 times that of the sample 9. In addition, the rigidity of the absorbent core 2 in the long-side direction is one in which samples 6 to 7 are high (hard) and samples 8 to 9 are low (soft). The product length L1 is 240mm for samples 6, 8, 175mm for sample 7, and 230mm for sample 9. In addition, all the samples 6 to 9 were prepared with leg circumference elastic members 10.
貼合性的評價,是與表1的評價方法相同。亦即,被試驗者利用目視觀察裝設各樣本6~9的人偶,或從樣本上碰觸人偶的臀部來進行二階段的評價。The evaluation of the adhesiveness was the same as the evaluation method of Table 1. That is, the subject performs two-stage evaluation by visually observing the puppets equipped with the samples 6 to 9 or touching the puppet's hips from the samples.
從表2的結果可知,在觀看高度H2為81.7mm及70mm的樣本6~7,其吸收性芯2對低體重兒的貼合性不佳。另一方面,可知在觀看高度H2為51mm及45mm的樣本8~9,其吸收性芯2對低體重兒的貼合性佳。From the results in Table 2, it can be seen that in the samples 6 to 7 with viewing heights H2 of 81.7 mm and 70 mm, the adherence of the absorbent core 2 to low-weight children is not good. On the other hand, it can be seen that the samples 8 to 9 having a viewing height H2 of 51 mm and 45 mm have good adhesion of the absorptive core 2 to low-weight infants.
於此,在低體重兒用的紙尿布1,是將觀看高度H2設成未滿70mm即可(H2<70mm)。觀看高度H2低,是指不易用包裝時的折線FL將紙尿布1對折,紙尿布1的裝設時,吸收性芯2邊沿著低體重兒的胯間部、臀部,邊容易裝設紙尿布1。因此,可讓吸收性芯2對低體重兒的貼合性提升。Here, in the paper diaper 1 for low-weight children, it is sufficient to set the viewing height H2 to less than 70 mm (H2 <70 mm). The low viewing height H2 means that it is not easy to fold the paper diaper 1 in half with the fold line FL during packaging. When the paper diaper 1 is installed, the absorbent core 2 is easy to install the paper diaper along the intercondylar portion and hip of the low-weight child 1. Therefore, the fit of the absorbent core 2 to a low-weight child can be improved.
又,在低體重兒用的紙尿布1,可使立體摺邊部用彈性構件9的伸長倍率小於腿圍彈性構件10的伸長倍率。Further, in the paper diaper 1 for a low-weight child, the expansion ratio of the elastic member 9 for the three-dimensional hem portion can be made smaller than the expansion ratio of the leg circumference elastic member 10.
紙尿布1在自然狀態,藉由兩彈性構件9、10的收縮,使肌膚側面朝內側彎曲。和腿圍彈性構件10相比,位在寬邊方向的內側的立體摺邊部用彈性構件9對於紙尿布1彎曲的變形的影響大。因此,設成上述的伸長倍率,能抑制紙尿布1的彎曲,且在包裝時的折線FL紙尿布1不易對折。The paper diaper 1 is in a natural state, and the side of the skin is bent inward by the contraction of the two elastic members 9 and 10. Compared with the leg circumference elastic member 10, the elastic member 9 for a three-dimensional hemming part located in the widthwise direction has a greater influence on the bending deformation of the paper diaper 1. Therefore, by setting the above-mentioned elongation ratio, the bending of the paper diaper 1 can be suppressed, and the folding line FL paper diaper 1 during packaging is not easily folded in half.
又,若吸收性芯2的長邊方向的剛性高,立體摺邊部用彈性構件9的伸長倍率高,則作成圖7A的狀態,紙尿布1以包裝時的折線FL折成銳角而立起,使得觀看高度H2變高。因此,也如表1及表2的結果所示,降低吸收性芯2的長邊方向的剛性,邊使吸收性芯2柔軟,邊降低立體摺邊部用彈性構件9的伸長倍率即可。這樣一來,增大觀看產品長L2除以產品長L1的值(L2/L1),可縮小觀看高度H2,而使紙尿布1不易對折。In addition, if the longitudinal rigidity of the absorbent core 2 is high, and the elongation ratio of the elastic member 9 for the three-dimensional hemming portion is high, the state shown in FIG. 7A is adopted. This makes the viewing height H2 higher. Therefore, as shown in the results of Tables 1 and 2, the rigidity of the absorptive core 2 in the longitudinal direction can be reduced, the absorptive core 2 can be made soft, and the elongation ratio of the elastic member 9 for the three-dimensional hemming portion can be reduced. In this way, increasing the value of the product length L2 divided by the product length L1 (L2 / L1) can reduce the viewing height H2 and make the diaper 1 difficult to fold in half.
具體而言,將立體摺邊部用彈性構件9的伸長倍率設定在1.3倍以上2.1倍以下即可。將伸長倍率降到2.1倍以下,紙尿布1變的不易對折。另一方面,將伸長倍率設在1.3倍以上,可讓立體摺邊部8立起,並抑制排泄物的漏出。Specifically, the expansion ratio of the elastic member 9 for a three-dimensional hemming portion may be set to 1.3 times or more and 2.1 times or less. When the elongation ratio is reduced to less than 2.1 times, the paper diaper 1 becomes difficult to fold in half. On the other hand, setting the elongation ratio to 1.3 times or more allows the three-dimensional hemming portion 8 to stand up and suppresses leakage of excrement.
又,將伸長倍率設在2.1倍以下,能適度抑制立體摺邊部8的立起。這樣一來,即使以立體摺邊部8接觸低體重兒的程度舒適地裝設紙尿布1,也可抑制吸收性芯2從低體重兒浮起的情況。Moreover, by setting the elongation ratio to 2.1 times or less, the standing of the three-dimensional hemming portion 8 can be appropriately suppressed. In this way, even if the paper diaper 1 is comfortably installed to such an extent that the three-dimensional hem portion 8 contacts the low-weight child, it is possible to prevent the absorbent core 2 from rising from the low-weight child.
彈性構件9、10的伸長倍率的測量,是用周知的方法進行即可。例如,在自然狀態的紙尿布1,測量測量對象的彈性構件的伸縮部(伸長狀態下固定在薄片的部位)的長邊方向的長度H0。接著,將紙尿布1朝長邊方向伸長到在紙尿布1產生的皺紋不能視認的程度的狀態,測量彈性構件的伸縮部的長邊方向的長度H1。而且,將長度H1除以長度H0的直設為伸長倍率(伸長倍率=H1/H0)。The measurement of the elongation ratios of the elastic members 9 and 10 may be performed by a known method. For example, in the paper diaper 1 in the natural state, the length H0 in the long-side direction of the stretchable portion (the portion fixed to the sheet in the stretched state) of the elastic member to be measured is measured. Next, the paper diaper 1 was extended to the state of the longitudinal direction so that the wrinkle which generate | occur | produced in the paper diaper 1 could not be recognized visually, and the length H1 of the longitudinal direction of the expansion-contraction part of the elastic member was measured. Then, the length H1 divided by the length H0 is taken as the elongation ratio (elongation ratio = H1 / H0).
<<包裝時的折線FL的緩和>> 圖8A及圖8C,是模仿護理師等的行為的行為與之後的紙尿布1的說明圖。圖8A及圖8B,是紙尿布1的概略立體圖,圖8C,是紙尿布1的概略剖視圖。圖9A及圖9B,是形成在紙尿布1的其他的折線FLa的說明圖,且為紙尿布1的概略剖視圖。<<< Easing the fold line FL at the time of packaging >> FIG. 8A and FIG. 8C are explanatory drawings which imitate the behavior of a caregiver etc. and the following diaper 1. FIG. 8A and 8B are schematic perspective views of the paper diaper 1, and FIG. 8C is a schematic cross-sectional view of the paper diaper 1. FIGS. 9A and 9B are explanatory diagrams of other fold lines FLa formed on the paper diaper 1, and are schematic cross-sectional views of the paper diaper 1.
如前述,容易用包裝時的折線FL將紙尿布1對折時,吸收性芯2容易從低體重兒浮起。其他,即使包裝時的折線FL的折疊習性強的情況,吸收性芯2也容易從低體重兒浮起。若折疊習性強,如圖4C的比較例的紙尿布1’,紙尿布1的折線FL部分折成銳角,而朝外側突出。因此,吸收性芯2不易沿著有曲線的臀部而浮起。As described above, when the diaper 1 is easily folded in half with the folding line FL at the time of packaging, the absorbent core 2 easily rises from a low-weight child. In addition, even if the folding habit of the fold line FL at the time of packaging is strong, the absorbent core 2 easily rises from a low-weight child. If the folding habit is strong, as shown in the paper diaper 1 'of the comparative example of Fig. 4C, the fold line FL of the paper diaper 1 is folded at an acute angle and protrudes outward. Therefore, the absorbent core 2 does not easily float along the curved hips.
可是,在醫院等,護理師等從包裝袋取出低體重兒用的紙尿布1之後,將紙尿布1朝長邊方向展開,確認垃圾的附著。又,護理師等用手搓揉裝設前的紙尿布1,使紙尿布1變的柔軟。此時,緩和包裝時的折線FL的折疊習性。However, in a hospital or the like, a caregiver or the like takes out the paper diaper 1 for a low-weight child from a packaging bag, and then unfolds the paper diaper 1 in a long direction to confirm adhesion of garbage. In addition, the nurse or the like rubs the paper diaper 1 before the installation with hands to make the paper diaper 1 soft. At this time, the folding habit of the fold line FL at the time of packaging is eased.
再者,本實施形態的紙尿布1,當護理師等進行搓揉紙尿布1等的行為時,會在紙尿布1形成包裝時的折線FL以外的其他的折線FLa。In the paper diaper 1 according to the present embodiment, when a caregiver or the like rubs the paper diaper 1 or the like, the paper diaper 1 forms a fold line FLa other than the fold line FL at the time of packaging.
模仿護理師等的行為,對紙尿布1進行以下行為。首先,將從包裝袋取出的被對折的紙尿布1如圖8A所示,朝長邊方向展開且伸長的狀態下,按壓在試驗台30的上面30a。此時,將紙尿布1的非肌膚側面1c朝上,將肌膚側面1d朝下。然後,將覆蓋紙尿布1的平面全面的大小的板子31放置在紙尿布1之上,將1kg的砝碼32放置在板子31之上,放置2分鐘。之後,取下砝碼32及板子31,使紙尿布1在試驗台30的上面30a之上成為自然狀態(圖8B及圖8C)。The following actions are performed on the diaper 1 by imitating the actions of a nurse or the like. First, as shown in FIG. 8A, the folded paper diaper 1 taken out of the packaging bag is extended in the longitudinal direction and stretched, and is pressed against the upper surface 30 a of the test stand 30. At this time, the non-skin side surface 1c of the diaper 1 is directed upward, and the skin side surface 1d is directed downward. Then, a board 31 covering the entire surface of the paper diaper 1 is placed on the paper diaper 1, and a weight 32 of 1 kg is placed on the board 31 and left for 2 minutes. Then, the weight 32 and the board 31 are removed, and the paper diaper 1 is brought into a natural state on the upper surface 30a of the test stand 30 (FIG. 8B and FIG. 8C).
在其自然狀態,吸收性芯2,是如圖9A所示成為具有:沿著試驗台30的上面30a的第1區域S1、以及從試驗台30的上面30a朝上方遠離的第2區域S2者。而且,在紙尿布1,是作成形成有成為第1區域S1與第2區域S2的邊界的其他的折線FLa。其他的折線FLa,是與包裝時的折線FL同樣,沿著寬邊方向折疊吸收性芯2的折線。In its natural state, as shown in FIG. 9A, the absorbent core 2 has a first region S1 along the upper surface 30 a of the test bed 30 and a second region S2 that is spaced upward from the upper surface 30 a of the test bed 30. . Further, in the paper diaper 1, another polyline FLa is formed so as to form a boundary between the first region S1 and the second region S2. The other folding line FLa is a folding line that folds the absorbent core 2 in the wide-side direction in the same manner as the folding line FL during packaging.
此外,吸收性芯2沿著試驗台30的上面30a,是指所謂吸收性芯2隔著頂面薄片3等接觸試驗台30的上面30a的情況。因此,紙尿布以包裝時的折線FL折成銳角而立起時,亦即,僅在吸收性芯2存在的區域、以及較這個更靠長邊方向外側的薄片部分3、4、5的邊界形成有其他的折線時為不包含者。In addition, the absorptive core 2 is along the upper surface 30a of the test stand 30, and refers to the case where the so-called absorptive core 2 contacts the upper surface 30a of the test stand 30 via the top sheet 3 or the like. Therefore, when the paper diaper stands up at an acute angle by folding the folding line FL at the time of packaging, that is, only in the area where the absorbent core 2 exists, and the borders of the sheet portions 3, 4, and 5 further outside in the long side direction are formed. Not included if there are other polylines.
將形成有包裝時的折線FL及其他的折線FLa的紙尿布1裝設在低體重兒,而以複數個折線FL、FLa沿著寬邊方向彎折吸收性芯2。亦即,吸收性芯2在長邊方向的不同的複數個位置被彎折。因此,如圖4C的比較例的紙尿布1’可防止僅包裝時的折線FL部分突出的情況,而使吸收性芯2沿著具有曲線的臀部彎曲。因此,可讓吸收性芯2對低體重兒的貼合性提升。The paper diaper 1 on which the fold line FL and other fold lines FLa at the time of packaging are formed is mounted on a low-weight child, and the absorbent core 2 is folded along the broad side direction with a plurality of fold lines FL and FLa. In other words, the absorptive core 2 is bent at a plurality of different positions in the longitudinal direction. Therefore, the paper diaper 1 'of the comparative example as shown in FIG. 4C can prevent the fold line FL from protruding only when it is packed, and the absorbent core 2 can be bent along the curved hips. Therefore, the fit of the absorbent core 2 to a low-weight child can be improved.
讓吸收性芯2的貼合性提升,使排泄尿不會傳到低體重兒的肌膚,而可抑制刺激低體重兒的肌膚的情況。又,進行低體重兒特有的姿勢時,在低體重兒的正確的臀部的位置,對齊腳的根部的位置,將腳拉起到適當的位置。By improving the conformability of the absorbent core 2, the excretion of urine does not reach the skin of the low-weight child, and the irritation of the skin of the low-weight child can be suppressed. In addition, when performing a posture specific to a low-weight child, align the position of the root of the foot with the correct hip position of the low-weight child and pull the foot to an appropriate position.
彙整以上,本實施形態的紙尿布1,是吸收性芯2具有狹窄部2A,腿圍的薄片部分的長度W3(參照圖1)長,低體重兒闔著腳的時會有吸收性芯2浮起的顧慮。可是,因為在紙尿布1形成有其他的折線FLa,所以,吸收性芯2容易沿著低體重兒的臀部,而可抑制吸收性芯2從低體重兒浮起。Taken together, the paper diaper 1 of this embodiment has an absorptive core 2 having a narrow portion 2A, and the length W3 (see FIG. 1) of the sheet portion around the legs is long. When a low-weight child is stomping, the absorptive core 2 is formed. Floating concerns. However, since the other fold line FLa is formed in the paper diaper 1, the absorptive core 2 can easily follow the buttocks of a low-weight child, and the absorptive core 2 can be suppressed from floating from a low-weight child.
在模仿護士等的行為的行為(圖8A)之後的紙尿布1,如圖9A所示,在以包裝時的折線FL彎折的山的兩側分別形成其他的折線FLa亦可。其他,如圖9B所示,以包裝時的折線FL彎折的山朝單側傾斜,與山傾斜之側相反側的吸收性芯2從試驗台30的上面30a朝上方遠離,也可僅在山傾斜之側形成有其他的折線FLa。As shown in FIG. 9A, after the diaper 1 after imitating the behavior of a nurse or the like (FIG. 8A), other fold lines FLa may be formed on both sides of the mountain folded by the fold line FL during packaging. In addition, as shown in FIG. 9B, the mountain bent by the folding line FL at the time of packaging is inclined toward one side, and the absorptive core 2 on the side opposite to the side inclined by the mountain is moved away from the upper surface 30a of the test stand 30, or may On the side of the mountain slope, another polyline FLa is formed.
可是,如圖9A所示,其他的折線FLa被形成在2處為理想。吸收性芯2的彎折起點多,所以吸收性芯2更容易沿著具有曲線的臀部,而使吸收性芯2對低體重兒的貼合性提升。However, as shown in FIG. 9A, it is preferable that other polylines FLa are formed at two places. The absorptive core 2 has a lot of bending starting points, so the absorptive core 2 is easier to follow the hip with a curve, and the fit of the absorptive core 2 to a low-weight child is improved.
又,在紙尿布1形成其他的折線FLa的方式,降低吸收性芯2的剛性,使吸收性芯2成為柔軟者即可。具體而言,將吸收性芯2的長邊方向、寬邊方向的剛性設在1.1N以下即可。這樣的方式,容易在紙尿布1形成其他的折線FLa。Further, another method of forming the folded line FLa in the paper diaper 1 may reduce the rigidity of the absorbent core 2 and make the absorbent core 2 soft. Specifically, the rigidity in the long-side direction and the wide-side direction of the absorbent core 2 may be set to 1.1 N or less. In this way, it is easy to form another fold line FLa in the paper diaper 1.
表3,是讓紙尿布1的寬邊方向的剛性變化,來評價低體重兒的腳的容易闔起性的結果。試作4種類的樣本10~13,測量紙尿布1的長邊方向的中央部,亦即,測量跨包裝時的折線FL的區域的寬邊方向的剛性。而且,被試驗者對於模仿低體重兒的人偶實際安裝各樣本10~13,評價闔起人偶的腳的時候的闔起容易性。Table 3 shows the change in the rigidity of the wide diaper 1 of the paper diaper 1 to evaluate the ease of lifting of the feet of a low-weight child. Four types of samples 10 to 13 were made, and the central portion in the longitudinal direction of the paper diaper 1 was measured, that is, the rigidity in the widthwise direction of the region across the fold line FL at the time of packaging was measured. In addition, the subjects actually mounted each of the samples 10 to 13 on a puppet imitating a low-weight child, and evaluated the ease of lifting when lifting the puppet's feet.
樣本10~13的規格,是接下來所述。樣本10的吸收性芯,是將氣流成型薄片2層重疊者,寬度為25mm。樣本11的吸收性芯,是將氣流成型薄片2層重疊者,寬度為40mm。樣本12的吸收性芯,是1層氣流成型薄片,寬度為35mm。樣本13的吸收性芯,是層積了紙漿纖維者,寬度為35mm。The specifications of samples 10 to 13 are described below. The absorptive core of Sample 10 is a laminate of two layers of air-formed sheets, and has a width of 25 mm. The absorptive core of Sample 11 is a laminate of two layers of air-formed sheets, and has a width of 40 mm. The absorptive core of Sample 12 was a single layer of air-formed sheet, and the width was 35 mm. The absorptive core of Sample 13 was a laminate of pulp fibers and had a width of 35 mm.
被試驗者對於腳的闔起容易性以3階段進行評價。具體而言,將感覺到「不易闔起人偶的腳,從紙尿布對人偶施加很強的力」的樣本評價為「×」,將感覺到「容易闔起人偶的腳,沒有從紙尿布對人偶施加很強的力」的樣本評價為「○」,將感覺到「容易闔起人偶的腳,從紙尿布幾乎沒有對人偶施力」的樣本評價為「◎」。The testees evaluated the ease of lifting the feet in three stages. Specifically, the sample that felt "the feet of the doll are not easy to lift and exert a strong force on the doll from the paper diaper" was evaluated as "×", and the feeling of "easy to lift the feet of the doll was not found. The sample of the diaper which exerts a strong force on the puppet was evaluated as "○", and the sample that felt "easy to lift the feet of the puppet and hardly exerted force on the puppet from the diaper" was evaluated as "◎".
從表3的結果,可知在寬邊方向的剛性為1.145N及1.103的樣本10~11為不易闔起人偶的腳。另一方面,可知寬邊方向的剛性為0.861N的樣本12為容易闔起人偶的腳。又,可知在寬邊方向的剛性為0.298N的樣本13為非常容易闔起人偶的腳。From the results in Table 3, it can be seen that samples 10 to 11 having a rigidity of 1.145N and 1.103 in the broad side direction are difficult to lift the feet of the doll. On the other hand, it can be seen that the sample 12 having a rigidity of 0.861N in the wide side direction is prone to lift the feet of the doll. In addition, it can be seen that the sample 13 having a rigidity of 0.298N in the wide side direction is very easy to lift the feet of the doll.
於此,將包含包裝時的折線FL的區域的吸收性芯2的寬邊方向的剛性設在1.1N以下即可。這樣一來,闔起裝設了紙尿布1的低體重兒的腳的時候,可抑制剛性高的吸收性芯2壓迫低體重兒的肌膚的情況。與此同時,在具備剛性低的吸收性芯2的紙尿布1容易形成有包裝時的折線以外的其他的折線FLa。因此,吸收性芯2更容易沿著具有曲線的臀部,而使吸收性芯2對低體重兒的貼合性提升。Here, the rigidity of the width direction of the absorptive core 2 in the area including the folding line FL at the time of packaging may be set to 1.1 N or less. In this way, when the feet of the low-weight child with the paper diaper 1 installed are lifted, it is possible to suppress the situation where the absorbent core 2 with high rigidity presses the skin of the low-weight child. At the same time, in the paper diaper 1 provided with the absorbent core 2 having low rigidity, it is easy to form a fold line FLa other than the fold line at the time of packaging. Therefore, it is easier for the absorptive core 2 to follow the curved hips, and the fit of the absorptive core 2 to a low-weight child is improved.
吸收性芯2的剛性的測量只要用周知的方法進行即可,並可例示以下的方法。首先,在寬邊方向的吸收性芯2的側端折朝長邊方向展開且伸長的狀態的紙尿布1。而且,讓吸收性芯2的側端部從試驗台延伸出。又,將數位側力計的端子以接觸吸收性芯2的側端的長邊方向的中央部(亦即,跨包裝時的折線FL的區域)的方式進行設置。然後,將數位側力計的端子朝紙尿布1的寬邊方向內側移動5mm左右。將端子推入吸收性芯2時的最大值(壓縮力)設為吸收性芯2的寬邊方向的剛性值。The rigidity of the absorbent core 2 may be measured by a known method, and the following methods can be exemplified. First, the side of the absorptive core 2 in the wide-side direction is folded in a state in which the paper diaper 1 is expanded and extended in the long-side direction. Furthermore, the side end part of the absorptive core 2 was extended from the test stand. Moreover, the terminal of the digital lateral force meter is provided so that it may contact the center part of the longitudinal direction of the side end of the absorptive core 2 (namely, the area | region which crosses the folding line FL at the time of packaging). Then, the terminal of the digital lateral force meter was moved toward the inside of the widthwise direction of the paper diaper 1 by about 5 mm. The maximum value (compressive force) when the terminal is pushed into the absorbent core 2 is set as the rigidity value of the absorbent core 2 in the width direction.
又,將吸收性芯2的密度設為未滿0.0155 g/cm3 即可。這麼一來,吸收性芯2變軟。因此,護理師等搓揉紙尿布1,而容易在紙尿布1(吸收性芯2)形成其他的折線FLa,而使吸收性芯2容易沿著具有曲線的臀部。The density of the absorbent core 2 may be less than 0.0155 g / cm 3 . As a result, the absorbent core 2 becomes soft. Therefore, the nurse or the like rubs the paper diaper 1 to easily form another fold line FLa on the paper diaper 1 (absorptive core 2), so that the absorbent core 2 can easily follow the curved hips.
尤其,將吸收性芯2的長邊方向的中央CL的密度,亦即,將形成有包裝時的折線FL的吸收性芯2的部位的密度設成未滿0.0155g/cm3 即可。這麼一來,包裝時的折線FL的折疊習性不易附著在吸收性芯2。又,護理師等搓揉紙尿布1,而容易緩和折疊習性。因此,可防止圖4C的比較例的紙尿布1’這樣的包裝時的折線FL部分的突出,而使吸收性芯2容易沿著具有曲線的臀部。In particular, the density of the center CL in the longitudinal direction of the absorptive core 2, that is, the density of the portion of the absorptive core 2 where the fold line FL at the time of packaging is formed may be less than 0.0155 g / cm 3 . As a result, the folding habit of the fold line FL at the time of packaging cannot easily adhere to the absorbent core 2. In addition, a nurse or the like rubs the paper diaper 1 to ease the folding habit. Therefore, the fold line FL at the time of packaging such as the paper diaper 1 'of the comparative example of FIG. 4C can be prevented from protruding, and the absorptive core 2 can be made to follow the hip which has a curve easily.
吸收性芯2的密度的測量只要用周知的方法進行即可。例如,從吸收性芯2切出測量對象部位,測量基重(g/cm2 )、及厚度(cm)。基重(g/cm2 )除以厚度(cm)算出密度(g/cm3 )。厚度的測量,是可例示例如使用三豐(股)製的針盤式厚度規ID-C1012C或與這個同等者,將接觸壓設定為3gf/cm2 對對象部位進行加壓來進行測量的方法。The measurement of the density of the absorptive core 2 should just be performed by a well-known method. For example, the measurement target portion is cut out from the absorbent core 2 and the basis weight (g / cm 2 ) and the thickness (cm) are measured. The basis weight (g / cm 2 ) is divided by the thickness (cm) to calculate the density (g / cm 3 ). The thickness measurement is an example. For example, a method such as using a dial thickness gauge ID-C1012C made by Mitutoyo Corporation or the equivalent, and setting the contact pressure to 3gf / cm 2 to pressurize the target part to measure is performed. .
又,詳細雖後述,可是在吸收性芯2,是在長邊方向的不同位置設有,將吸收性芯2沿著寬邊方向彎折地加以誘導的複數個彎折誘導部21a~21c(一對的缺口部2a~22c)。Although described in detail later, the absorptive core 2 is provided with a plurality of bending induction portions 21a to 21c at different positions in the longitudinal direction, and the absorptive core 2 is induced to bend in the wide-side direction. A pair of notches 2a to 22c).
因此,護理師等搓揉紙尿布1等,而容易在彎折誘導部21a~21c彎折吸收性芯2,且容易在紙尿布1形成包裝時的折線FL以外的其他的折線FLa。因此,吸收性芯2容易沿著具有曲線的臀部。Therefore, the nurse or the like rubs the paper diaper 1 or the like, easily bends the absorbent core 2 at the bending induction portions 21a to 21c, and easily forms the fold line FLa other than the fold line FL when the paper diaper 1 is packed. Therefore, the absorptive core 2 is easy to follow a hip which has a curve.
再者,假設護理師等進行搓揉紙尿布1等的行為時,對於前述表2的樣本6~9與上述同樣將砝碼32放置在紙尿布1之上,測量之後的觀看高度H3。然後,被試驗者對於模仿低體重兒的人偶實際安裝各樣本6~9,進行貼合性的評價。Furthermore, suppose that when a nurse or the like rubs the paper diaper 1 or the like, the samples 6 to 9 of Table 2 are placed on the paper diaper 1 in the same manner as described above, and the viewing height H3 after the measurement is measured. Then, the subjects actually mounted each sample 6 to 9 on a puppet imitating a low-weight child, and evaluated the fit.
貼合性的評價,是被試驗者利用目視觀察裝設各樣本6~9的人偶,或從樣本上碰觸人偶的臀部來進行二階段的評價。可是,將砝碼32放置之後的觀看高度H3的評價(表2的貼合性評價2),假設搓揉紙尿布1之後進行裝設,則被實驗者更嚴格進行觀看高度H2的評價(表2的貼合性評價1)。The evaluation of the fit is a two-stage evaluation performed by the test subject by visually observing the puppets installed with each of the samples 6-9, or touching the hips of the puppets from the samples. However, the evaluation of the viewing height H3 after placing the weight 32 (adhesion evaluation 2 in Table 2), if the paper diaper 1 is kneaded and installed, the tester will perform the evaluation of the viewing height H2 more strictly (Table Evaluation of adhesion of 2) 1).
從表2的結果,在全部的樣本6~9,相較於觀看高度H2,放置砝碼32之後的觀看高度H3變小。亦即,若緩和包裝時的折線FL的折疊習性,可知紙尿布1變的不易對折。From the results in Table 2, in all the samples 6 to 9, the viewing height H3 after placing the weight 32 was smaller than the viewing height H2. That is, if the folding habit of the fold line FL at the time of packaging is relaxed, it can be seen that the diaper 1 becomes difficult to fold in half.
而且,從表2的結果可知,在觀看高度H3為73mm及62mm的樣本6~7,吸收性芯2對低體重兒的貼合性不佳。另一方面,可知在觀看高度H3為48mm及25mm的樣本8~9,吸收性芯2對低體重兒的貼合性佳。In addition, from the results in Table 2, it can be seen that in samples 6 to 7 with viewing heights H3 of 73 mm and 62 mm, the absorptive core 2 has poor adhesion to low-weight children. On the other hand, it can be seen that the samples 8 to 9 having a height H3 of 48 mm and 25 mm have a good adhesion of the absorbent core 2 to low-weight infants.
於此,在低體重兒用的紙尿布1,將對折的紙尿布1朝長邊方向展開且伸長的狀態下,將肌膚側面朝下按壓在台的上面,將板子31及砝碼32放置在紙尿布1之上放置2分鐘之後,使自然狀態時的觀看高度H3成為60mm以下即可(H3≦60mm)。Here, in the paper diaper 1 for a low-weight child, the folded paper diaper 1 is extended and extended in a long side direction, and the skin side is pressed down on the upper surface of the table, and the board 31 and the weight 32 are placed on After being left on the diaper 1 for 2 minutes, the viewing height H3 in the natural state may be 60 mm or less (H3 ≦ 60 mm).
這麼一來,即使在裝設前進行搓揉紙尿布1等的對策的護理師等,也可認識吸收性芯2對低體重兒的貼合性良好的情況,而對紙尿布1的貼合性滿足並加以使用。In this way, even a nurse or the like who takes measures to knead the paper diaper 1 before installation can recognize that the absorptive core 2 has good adhesion to low-weight children, and can attach the paper diaper 1 Sexual satisfaction and use.
<<吸收性芯2的形狀>> 低體重兒用的紙尿布1具有以下的特徵為理想。可是,吸收性芯2只要具備狹窄部2A即可,而不限於以下所示者。<<< Shape of Absorptive Core 2 >> The paper diaper 1 for low birth weight children has the following characteristics. However, the absorptive core 2 is not limited to the one described below as long as it includes the narrow portion 2A.
如圖5所示,在長邊方向從吸收性芯2的中央CL到狹窄部2A的一端2A1(與黏扣帶7側相反側的非帶片側之端2A1)的長度L5,是吸收性芯2的長邊方向的長度L4的22%以上的長度即可(L5≧L4×0.22)。As shown in FIG. 5, the length L5 from the center CL of the absorbent core 2 to one end 2A1 of the narrow portion 2A (the end 2A1 on the non-belt side opposite to the hook-and-loop tape 7 side) in the longitudinal direction is the absorbent core A length of 22% or more of the length L4 in the longitudinal direction of 2 is sufficient (L5 ≧ L4 × 0.22).
再者,在長邊方向,狹窄部2A較吸收性芯2的中央CL、與吸收性芯2的非帶片側的一端2b的中央CL2更延伸到長邊方向的外側即可。In the longitudinal direction, the narrowed portion 2A may extend to the outside in the longitudinal direction from the center CL of the absorptive core 2 and the center CL2 of one end 2b of the non-strip side of the absorptive core 2.
這麼一來,如圖3A所示,非帶片側的第2腰圍部1C以覆蓋腹側的方式被裝設的通常裝設時,藉由朝非帶片側延伸的狹窄部2A容易拉起低體重兒的腳。換言之,形成狹窄部2A位在朝非帶片側拉起腳的低體重兒的胯間部。因此,闔起低體重兒的腳的時候,可抑制用剛性高的吸收性芯2壓迫低體重兒的肌膚的情況。假設,長度L5未滿長度L4的22%的長度的話,狹窄部2A不易位在拉起腳的低體重兒的胯間部。In this way, as shown in FIG. 3A, when the second waistline portion 1C on the non-belt side is installed so as to cover the ventral side, the low weight is easily pulled up by the narrow portion 2A extending toward the non-belt side. Children's feet. In other words, the narrowed portion 2A is formed in the intercondylar portion of a low-weight child whose foot is pulled toward the non-belt side. Therefore, when the feet of the low-weight child are lifted, it is possible to suppress the skin of the low-weight child from being pressed by the rigid absorbent core 2. Assuming that the length L5 is less than 22% of the length L4, the narrow part 2A cannot be translocated in the intercondylar part of a low-weight child who has raised his or her feet.
同樣,在長邊方向從吸收性芯2的中央CL到狹窄部2A的另一端2A2(作為黏扣帶7側的帶片側之端2A2)的長度L6,是吸收性芯2的長邊方向的長度L4的22%以上的長度即可(L6≧L4×0.22)。Similarly, the length L6 from the center CL of the absorptive core 2 to the other end 2A2 of the narrow portion 2A (which is the end 2A2 on the side of the strap on the side of the hook-and-loop fastener 7) is the lengthwise direction of the absorptive core 2. A length of 22% or more of the length L4 is sufficient (L6 ≧ L4 × 0.22).
再者,在長邊方向,狹窄部2A較吸收性芯2的中央CL、與吸收性芯2的帶片側的另一端2c的中央CL3更延伸到長邊方向的外側即可。In the longitudinal direction, the narrowed portion 2A may extend to the outside in the longitudinal direction from the center CL of the absorptive core 2 and the center CL3 of the other end 2c on the strip side of the absorptive core 2.
這麼一來,如圖3B所示,即使帶片側的第1腰圍部1A以覆蓋腹側的方式被裝設的前後倒著裝設的情況時,藉由朝帶片側延伸的狹窄部2A容易拉起低體重兒的腳。換言之,形成狹窄部2A位在朝帶片側拉起腳的低體重兒的胯間部。因此,闔起低體重兒的腳的時候,可抑制用剛性高的吸收性芯2壓迫低體重兒的肌膚的情況。假設,長度L6未滿長度L4的22%的長度的話,狹窄部2A不易位在拉起腳的低體重兒的胯間部。In this way, as shown in FIG. 3B, even if the first waistline portion 1A on the belt side is installed upside down to cover the ventral side, the narrow portion 2A extending toward the belt side is easily pulled up. Feet of low birth weight infants. In other words, the narrow part 2A is formed in the intercondylar part of a low-weight child who pulls his foot toward the belt side. Therefore, when the feet of the low-weight child are lifted, it is possible to suppress the skin of the low-weight child from being pressed by the rigid absorbent core 2. Assuming that the length L6 is less than 22% of the length L4, the narrow part 2A cannot be translocated in the intercondylar part of a low-weight child who has raised his or her feet.
又,如圖5所示,狹窄部2A的寬邊方向的兩側端2a具有沿著長邊方向的直線部2A3即可。此時,例如比起吸收性芯2的側端成為朝寬邊方向的內側凸的圓弧形狀時,在長邊方向的更廣大的範圍,可縮窄吸收性芯2的寬度。具體而言,不僅吸收性芯2的長邊方向的中央CL,即使在直線部2A3,也可將吸收性芯2的寬度設在15mm以上45mm以下。因此,容易拉起低體重兒的腳。又,闔起低體重兒的腳的時候,可抑制用吸收性芯2壓迫低體重兒的肌膚的情況。Further, as shown in FIG. 5, both side ends 2 a in the wide-side direction of the narrow portion 2A may have a straight portion 2A 3 along the long-side direction. At this time, for example, the width of the absorptive core 2 can be narrowed over a wider range in the long-side direction than when the side ends of the absorptive core 2 have an arc shape convex toward the inside in the wide-side direction. Specifically, the width of the absorptive core 2 can be set to 15 mm or more and 45 mm or less, not only at the center CL in the longitudinal direction of the absorptive core 2 but also at the straight portion 2A3. Therefore, it is easy to pull up the feet of a low-weight child. In addition, when the feet of a low-weight child are lifted, it is possible to suppress the pressure on the skin of the low-weight child with the absorbent core 2.
再者,本實施形態的吸收性芯2,是相對於長邊方向的中央CL在長邊方向的兩側設有直線部2A3。因此,即使在通常裝設紙尿布1時,在前後倒著裝設時,也容易拉起低體重兒的腳。The absorptive core 2 of this embodiment is provided with straight portions 2A3 on both sides in the longitudinal direction with respect to the center CL in the longitudinal direction. Therefore, even when the paper diaper 1 is usually installed, it is easy to pull up the feet of a low-weight child when installed backwards.
又,增長狹窄部2A,也可將因排尿使顏色變化的指示劑12收在狹窄部2A。在狹窄部2A,指示部12容易反應。因此,即使低體重兒的少的尿量也可讓指示部12反應,而容易知道紙尿布1的更換時間。In addition, by growing the narrowed portion 2A, the indicator 12 that changes color due to urination may be collected in the narrowed portion 2A. In the narrow portion 2A, the indicator portion 12 easily reacts. Therefore, even if the low-weight child has a small amount of urine, the indicator portion 12 can be made to react, and it is easy to know the replacement time of the paper diaper 1.
又,在狹窄部2A,從寬邊方向中的吸收性芯2的側端到紙尿布1的側端的腿圍的薄片部分的長度W3長(參照圖1),可確保立體摺邊部8的立起高度。於此,如圖1及圖5所示,相較將紙尿布1朝長邊方向展開且伸長的狀態中的立體摺邊部用彈性構件9的伸縮部的長度L9更增長狹窄部2A的長邊方向的長度L10即可(L9<L10)。Further, in the narrow portion 2A, the length W3 of the sheet portion from the side end of the absorbent core 2 in the wide side direction to the side end of the paper diaper 1 is long (see FIG. 1), and the three-dimensional hem portion 8 can be secured. Standing height. Here, as shown in FIGS. 1 and 5, the length L9 of the expansion and contraction portion of the elastic member 9 for the three-dimensional hem portion in a state where the diaper 1 is extended and extended in the longitudinal direction is longer than the length of the narrow portion 2A. The length L10 in the lateral direction is sufficient (L9 <L10).
這麼一來,跨立體摺邊部用彈性構件9的伸縮部的長的範圍,可配置狹窄部2A,而更確實可讓立體摺邊部8立起。因此,在立體摺邊部8能攔阻排泄液。In this way, the narrow part 2A can be arranged across the long range of the expansion and contraction part of the elastic member 9 for the three-dimensional hemming part, and the three-dimensional hemming part 8 can be surely stood up. Therefore, excretory fluid can be blocked in the three-dimensional hemming portion 8.
可是,狹窄部2A的長度,將紙尿布1朝長邊方向展開且伸長的狀態圖狀態(圖1)下,設成以下即可。在長邊方向,從紙尿布1的非帶片側(另一方側)之端1a到狹窄部2A的非帶片側之端2A1的長度L7,是從紙尿布1的帶片側(一方側)之端1b到黏扣帶7的非帶片側之端7a的長度L8以上即可(L7≧L8)。However, the length of the narrowed portion 2A can be set to the following in a state diagram state (FIG. 1) in which the paper diaper 1 is stretched and extended in the longitudinal direction. In the longitudinal direction, the length L7 from the end 1a on the non-strip side (the other side) of the diaper 1 to the end 2A1 on the non-strip side of the narrow portion 2A is the end from the strip side (one side) of the diaper 1 The length from 1b to the non-belt-side end 7a of the hook-and-loop fastener 7 is greater than or equal to L8 (L7 ≧ L8).
通常裝設紙尿布1時,第2腰圍部1C中的黏扣帶7之端7a的大概其卡止位置,在紙尿布1的非帶片側之端1a到長邊方向的中央CL側,成為遠離上述長度L8的位置p1(參照圖1及圖3C)。沒有將低體重兒的腳拉起到較黏扣帶7的卡止位置p1位於長邊方向的外側。因此,將狹窄部2A之端2A1配置在較位置p1更靠長邊方向的中央CL側即可。這樣,不會將狹窄部2A不需要地增長,可確保吸收性芯2的吸收能力。Generally, when the paper diaper 1 is installed, the approximate locking position of the end 7a of the hook and loop tape 7 in the second waistline portion 1C is from the end 1a on the non-tape side of the paper diaper 1 to the center CL side in the longitudinal direction. A position p1 away from the length L8 (see FIGS. 1 and 3C). The foot of the low-weight child is not pulled up to the locking position p1 of the hook and loop fastener 7 and is located outside in the longitudinal direction. Therefore, the end 2A1 of the narrow portion 2A may be disposed on the center CL side in the longitudinal direction more than the position p1. In this way, the narrow portion 2A is not increased unnecessarily, and the absorption capacity of the absorbent core 2 can be secured.
又,如圖5所示,在狹窄部2A,是在長邊方向排列配置有將吸收性芯2沿著寬邊方向彎曲地加以誘導的第1彎折誘導部21a、第2彎折誘導部21b、及第3彎折誘導部21c。As shown in FIG. 5, in the narrow portion 2A, the first bend inducing portion 21 a and the second bend inducing portion are arranged in a line in the longitudinal direction to align the absorptive core 2 in a curved direction. 21b and the third bending induction portion 21c.
詳細是在狹窄部2A的長邊方向的中央部配置有第2彎折誘導部21b。第1彎折誘導部21a較第2彎折誘導部21b更被配置在長邊方向的帶片側(一方側)。第3彎折誘導部21c較第2彎折誘導部21b更被配置在長邊方向的非帶片側(另一方側)。In detail, the 2nd bending induction part 21b is arrange | positioned in the center part of the narrow part 2A in the longitudinal direction. The 1st bending induction part 21a is arrange | positioned on the strip side (one side) of a longitudinal direction rather than the 2nd bending induction part 21b. The 3rd bending induction part 21c is arrange | positioned on the non-belt side (the other side) of a longitudinal direction rather than the 2nd bending induction part 21b.
在本實施形態的吸收性芯2,就第1~第3彎折誘導部21a~21c來說,在狹窄部2A的寬邊方向的兩側部設有朝寬邊方向的內側形成凸的一對的缺口部22a~22c。一對的缺口部22a~22c,是相對於在寬邊方向對分吸收性芯2的不圖示的中心線形成對稱,而對稱被配置。此外,缺口部22a~22c不限於圖5所示的山形狀,例如也可為長方形狀,也可為切線等。In the absorptive core 2 of this embodiment, in the first to third bending induction portions 21a to 21c, one of the two sides of the narrow portion 2A in the wide-side direction is provided with a convex portion formed inward in the wide-side direction. The pair of notches 22a to 22c. The pair of cutout portions 22a to 22c are symmetrically arranged with respect to a center line (not shown) that divides the absorbent core 2 in the broad side direction, and are arranged symmetrically. In addition, the cutout portions 22a to 22c are not limited to the mountain shape shown in FIG. 5, and may be, for example, rectangular or tangent.
在缺口部22a~22c,和周圍的區域相比構成吸收性芯2的構件(液體吸收性纖維等)的基重(g/cm2 )變低、或構成吸收性芯2的構件不存在。因此,在設有一對的缺口部22a~22c的吸收性芯2的部位,藉由與周圍的區域的剛性差,容易沿著寬邊方向彎曲吸收性芯2。In the cutout portions 22 a to 22 c, the basis weight (g / cm 2 ) of a member (liquid-absorbent fiber or the like) constituting the absorbent core 2 is lower than that of the surrounding area, or a member constituting the absorbent core 2 does not exist. Therefore, at the portion where the absorptive core 2 of the pair of notches 22a to 22c is provided, the absorptive core 2 is easily bent in the broad direction due to the poor rigidity with the surrounding area.
如圖3C所示,拉起腳的低體重兒的胯間部抵接在較紙尿布1的長邊方向的中央部偏置到一方側的部位。因此,相對於仰躺拉起腳的低體重兒,從接觸地板的臀部開始舉起腳的位置(F1)有紙尿布1的彎折起點即可。又,在拉起腳的腹側的根部的位置(F2),有紙尿布1的彎折起點亦可。這麼一來,抵接在低體重兒的胯間部的紙尿布1的部位(F1~F2)成為底,紙尿布1容易立體地變形。因此,紙尿布1容易沿著拉起腳的低體重兒,而使貼合性提升。As shown in FIG. 3C, the intercondylar portion of the low-weight child with the raised leg abuts on a portion offset to one side from the central portion in the longitudinal direction of the paper diaper 1. Therefore, with respect to a low-weight child who lays on his back with his feet raised, the starting point (F1) of the diaper 1 can be raised from the position where the buttocks touch the floor. Further, at the position (F2) at which the root on the ventral side of the foot is pulled up, there may be a bending start point of the diaper 1. In this way, the portion (F1 to F2) of the paper diaper 1 that abuts the intersacral part of a low-weight child becomes the bottom, and the paper diaper 1 is easily three-dimensionally deformed. Therefore, the paper diaper 1 is easy to follow the low-weight child who pulls up a leg, and it improves adhesiveness.
在通常裝設紙尿布1的低體重兒的胯間部,第2彎折誘導部21b及第3彎折誘導部21c間的部位貼合。而且,第2彎折誘導部21b及第3彎折誘導部21c沿著朝非帶片側拉起腳的低體重兒彎折,而使紙尿布1立體變形,並貼合在低體重兒的身體。A portion between the second bend induction portion 21b and the third bend induction portion 21c is adhered to the intercondylar portion of a low-weight child in which the diaper 1 is usually installed. In addition, the second bending inducing portion 21b and the third bending inducing portion 21c are bent along the low-weight child who pulls the foot toward the non-belt side to deform the diaper 1 three-dimensionally and fit the body of the low-weight child. .
同樣,在前後倒著裝設紙尿布1的低體重兒的胯間部,第1彎折誘導部21a及第2彎折誘導部21b間的部位貼合。而且,第1彎折誘導部21a及第2彎折誘導部21b沿著朝帶片側拉起腳的低體重兒彎折,而使紙尿布1立體變形,並貼合在低體重兒的身體。Similarly, the inter-condylar portion of a low-weight child with the paper diaper 1 installed on the front and back, and the portions between the first bend induction portion 21a and the second bend induction portion 21b are bonded together. In addition, the first bending inducing portion 21a and the second bending inducing portion 21b are bent along the low-weight child who pulls up the foot toward the belt side, so that the diaper 1 is three-dimensionally deformed and fits the body of the low-weight child.
如此,在吸收性芯2的長邊方向的3處設置彎折誘導部21a~21c,在通常裝設紙尿布1時,前後倒著裝設時,也貼合在採取低體重兒特有的姿勢的低體重兒的身體。In this manner, the bending induction portions 21a to 21c are provided at three places in the longitudinal direction of the absorbent core 2. When the paper diaper 1 is normally installed, and when it is installed upside down, it is also suitable for taking a posture unique to a low-weight child. The body of a low birth weight infant.
又,吸收性芯2具有複數個彎折誘導部21a~21c,並具有複數個彎折起點,可緩和紙尿布1在包裝時的折線FL對折。因此,如圖4C的比較例的紙尿布1’,可防止紙尿布1的包裝時的折線FL部分朝外側突出的情況,使紙尿布1容易沿著低體重兒的胯間部、臀部彎曲。因此,可進一步抑制吸收性芯從低體重兒的胯間部、臀部浮起。In addition, the absorbent core 2 has a plurality of bend inducing portions 21a to 21c and a plurality of bend starting points, and can ease the folding of the fold line FL of the paper diaper 1 during packaging. Therefore, as shown in the paper diaper 1 'of the comparative example of FIG. 4C, the fold line FL at the time of packaging of the paper diaper 1 can be prevented from protruding to the outside, and the paper diaper 1 can be easily bent along the intercondylar portion and the buttocks of a low-weight child. Therefore, it is possible to further suppress the absorptive core from floating from the intercondylar part and the buttocks of a low-weight child.
再者,本實施形態的吸收性芯2,是在狹窄部2A的長邊方向之端配置有第1彎折誘導部21a及第3彎折誘導部21c,亦即,被配置在吸收性芯2的寬度開始變窄的部位。因此,第1彎折誘導部21a的缺口部22a及第3彎折誘導部21c的缺口部22c的一部分,是藉由朝狹窄部2A的寬邊方向的內側傾斜的外形線2A4所形成。The absorptive core 2 according to the present embodiment has the first bend induction portion 21a and the third bend induction portion 21c at the ends in the longitudinal direction of the narrow portion 2A, that is, is disposed on the absorbent core. 2 where the width starts to narrow. Therefore, the notch portion 22a of the first bend induction portion 21a and a part of the notch portion 22c of the third bend induction portion 21c are formed by the outline line 2A4 inclined toward the inner side in the width direction of the narrow portion 2A.
因此,在拉起腳的腹側的腳的根部(圖3C的F2)可彎折紙尿布1,而使紙尿布1貼合在低體重兒的身體。又,可使朝狹窄部2A的寬邊方向的內側傾斜的外形線2A4的傾斜變陡。又,在長邊方向更寬廣的範圍,可縮窄吸收性芯2的寬度,而容易拉起低體重兒的腳。又,闔起低體重兒的腳的時候,可抑制用吸收性芯2壓迫低體重兒的肌膚的情況。Therefore, the paper diaper 1 can be bent at the root of the foot (F2 in FIG. 3C) on the ventral side of the pulled up foot, and the paper diaper 1 can be fitted to the body of a low-weight child. In addition, the inclination of the outline line 2A4 inclined toward the inner side in the width direction of the narrow portion 2A can be made steeper. In addition, in a wider range in the longitudinal direction, the width of the absorbent core 2 can be narrowed, and the feet of a low-weight child can be easily pulled up. In addition, when the feet of a low-weight child are lifted, it is possible to suppress the pressure on the skin of the low-weight child with the absorbent core 2.
此外,不限於用缺口部22a~22c形成第1~第3彎折誘導部21a~21c。例如,也可在製造工程,施予沿著寬邊方向彎曲吸收性芯2的彎曲加工、或使構成吸收性芯2的構件的基重沿著寬邊方向降低、或在吸收性芯2的寬邊方向的中央部形成沿著寬邊方向的細縫的方式形成第1~第3彎折誘導部21a~21c。The first to third bending induction portions 21a to 21c are not limited to the cutout portions 22a to 22c. For example, in the manufacturing process, a bending process of bending the absorptive core 2 in the broad side direction may be applied, or the basis weight of the members constituting the absorptive core 2 may be reduced in the broad side direction, or The first to third bending induction portions 21a to 21c are formed so that a slit in the wide side direction is formed in the central portion in the wide side direction.
如以上,本實施形態的吸收性芯2,是相對於長邊方向的中央CL形成對稱形狀。因此,相對於吸收性芯2的長邊方向的中央CL在長邊方向的兩側設置彎折誘導部(21a、21c)、或設置吸收性芯2的直線部2A3。因此,也可通常裝設紙尿布1,也可前後倒著裝設,在哪種裝設時也能獲得同樣的效果。As described above, the absorptive core 2 of this embodiment has a symmetrical shape with respect to the center CL in the longitudinal direction. Therefore, a bending induction portion (21a, 21c) or a straight portion 2A3 of the absorptive core 2 is provided on both sides in the longitudinal direction with respect to the center CL of the absorptive core 2 in the long-side direction. Therefore, the paper diaper 1 can be installed normally, and it can also be installed upside down, and the same effect can be acquired in any installation.
以上,雖針對本發明的實施形態進行說明,可是,上述的實施形態是為了容易本發明的理解者,而不是用來限定本發明進行解釋者。又,本發明只要不偏離其宗旨,得以變更、改良,且不用說本發明當然也含有其等價物。Although the embodiments of the present invention have been described above, the embodiments described above are intended to facilitate the understanding of the present invention, and are not intended to limit the interpretation of the present invention. In addition, the present invention can be changed and improved as long as it does not deviate from the gist thereof, and it goes without saying that the present invention also includes equivalents thereof.
