===關於紙尿褲1的穿著方法===
紙尿褲1,可用複數種方法來穿著。
例如,作為一般的內褲型紙尿褲(參照圖1),是讓穿著者的腳從腰部周邊開口部BH進入腿部周邊開口部LH,以將腰部周邊部20、30包圍穿著者之腰部周邊的方式拉起藉此可成為穿著狀態。
===About how to wear
且,如上述般穿著成內褲型的拋棄式紙尿褲之後,以切斷引導部(後述)來切斷腹側腰部周邊部20,將結合部5的卡合部51卡合於腹側腰部周邊部20,形成腰部周邊開口藉此可成為穿著狀態。藉此,可調整卡合部51的卡合位置,容易密貼於穿著者的腰部周邊。Furthermore, after wearing the panty-type disposable diaper as described above, the abdominal waist
此外,事先以切斷引導部來切斷腹側腰部周邊部20,使左右方向的一方側為所謂黏貼型紙尿褲的形態(沒有形成腿部周邊開口部LH的狀態),使左右方向的另一方側為內褲型紙尿褲的形態(形成有腿部周邊開口部LH的狀態)亦可穿著。In addition, the abdominal waist
首先,以切斷引導部來切斷腹側腰部周邊部20,讓穿著者之另一方側的腳(在紙尿褲1是穿著者的右腳)通過左右方向的另一方側(內褲型紙尿褲的形態)的腿部周邊開口部LH,之後將紙尿褲1拉起到穿著者的股間部,之後,以密貼於穿著者之腰部周邊的方式,使結合部5的卡合部51卡合於腹側腰部周邊部20,而形成腰部周邊開口,藉此成為穿著狀態。First, the abdominal waist
藉由如此地穿著,即使對於例如腳會亂動而難以讓雙腳通過內褲型之拋棄式紙尿褲之兩側之腿部周邊開口部LH的乳幼兒,只要可讓穿著者的單腳通過腿部周邊開口部LH的話,之後以結合部5(卡合部51)來卡合,藉此可容易成為穿著狀態。且,穿著者本身,在進行穿著紙尿褲1的情況,會有難以在廁所等穿著一般的黏貼型紙尿褲(在左右方向的兩側具備膠帶的紙尿褲)的情況,但使左右方向的一方側為內褲型的形態,使另一方側為具備結合部5(黏貼型)的形態,藉此容易穿著,且容易調整腰部周邊的密貼性。By wearing it in this way, for example, even for infants whose feet move around and it is difficult to pass the legs through the leg peripheral openings LH on both sides of the panty-type disposable diaper, as long as the wearer can pass one leg through the legs. The peripheral opening LH is then engaged with the coupling portion 5 (engagement portion 51), thereby making it easy to put it into a wearing state. Moreover, when the wearer himself wears the
又,將使用後的紙尿褲1從身體卸下之際,以切斷引導部來分離腹側腰部周邊部20,從穿著者的身體卸下紙尿褲1之左右方向的一方側,將另一方側的腳從左右方向之另一方側的腿部周邊開口部LH抽出,藉此可將紙尿褲1從穿著者的身體卸下。Furthermore, when the used
===關於腹側腰部周邊部20的切斷===
針對腹側腰部周邊部20的切斷,使用圖5及圖6來說明。圖5,是針對腹側腰部周邊部20的分離及腰部周邊開口的形成來說明的圖。圖6,是針對腹側腰部周邊部20的切斷動作來說明的圖。圖5,是說明圖4中的A-A箭頭視角之剖面之構造的圖。又,圖5及圖6是示意圖,尺寸等並不一定正確。

圖5A,是圖1等所示之內褲型之狀態的紙尿褲1。也就是說,腹側腰部周邊部20並未切斷,而是形成使腹側腰部周邊部20與背側腰部周邊部30透過接合部2a、2b來連接的腰部周邊開口。從圖5A所示之狀態,將抓住結合部5的前端部並朝向非肌膚側拉起的狀態,示於圖5B及圖6A。Fig. 5A shows the
然後,如圖6A所示般,以單手抓住腰部周邊部20,以另一隻手抓住結合部5,分別朝向左右方向的外側拉開,藉此如圖5C及圖6B所示般,腹側腰部周邊部20會沿著切斷引導部被切斷,使左右方向的一方側與另一方側分離。「切斷引導部」,是指在切斷腹側腰部周邊部20之至少一部分之際的引導部。紙尿褲1中,將腹側腰部周邊部20與結合部5予以固定的固定部F1,是作為切斷引導部來發揮功能。具體來說,如圖6A所示般,在分別抓著腹側腰部周邊部20與結合部5的狀態往左右方向拉開的話,首先,拉動的力會集中在切斷引導部(固定部F1)之中位於最前端部側的前端部側之端部亦即切斷引導起點K,之後,沿著從切斷引導部的切斷引導起點K朝向上側且基端部側來傾斜的傾斜部與從切斷引導起點K朝向下側且基端部側來傾斜的傾斜部來傳遞力。然後,以固定部F1之左右方向之另一方側的端部CE為邊界,使腹側腰部周邊部20被切斷,腹側腰部周邊部20,被分離成不具備結合部5的一方側之部分與具備結合部5的另一方側之部分。Then, as shown in FIG. 6A , grasp the waist
之後,因應必要,如圖5D所示般,將結合部5的卡合部51卡合於腹側腰部周邊部20的被卡合部25,藉此形成紙尿褲1的腰部周邊開口。在將卡合部51卡合於被卡合部25的狀態下,使分離之腹側腰部周邊部之左右方向的一方側部分與另一方側部分,在前後方向(厚度方向)重疊地將卡合部51卡合於被卡合部25亦可,使分離之腹側腰部周邊部之左右方向的一方側部分與另一方側部分,在前後方向(厚度方向)不重疊地將卡合部51卡合於被卡合部25亦可。藉由調整卡合部51的卡合位置,而可調整紙尿褲1之腰部周邊開口的大小。Thereafter, if necessary, as shown in FIG. 5D , the engaging
===關於切斷引導部===
紙尿褲1,其腹側腰部周邊部20與背側腰部周邊部30之左右方向之一方側的端部是以接合部2a來接合,結合部5的基端部是以固定部F1來固定於腹側腰部周邊部20。結合部5的前端部,具有可分離地卡合於腹側腰部周邊部20之非肌膚側面的卡合部51,將結合部5與腹側腰部周邊部20予以固定的固定部F1之至少一部分,是切斷引導部。具體來說,在紙尿褲1,若將腹側腰部周邊部20與結合部5分別往左右方向的外側拉開的話,會以固定部F1(切斷引導部)之左右方向之另一方側的端部CE為邊界使腹側腰部周邊部20被切斷。

以往,已知為了切斷拋棄式紙尿褲的腰部周邊部20、30而設有撕裂線等。對此,紙尿褲1,是將用來將結合部5固定於腹側腰部周邊部20的固定部F1亦作為切斷引導部來發揮功能,故不必另外設置撕裂線等之切斷引導部。藉此,可進行腹側腰部周邊部20的切斷,並且在紙尿褲1的製造過程中,不需要形成撕裂線的工程等之形成切斷引導部用的製造工程,可提供以簡略化的製造工程來製造的紙尿褲1。Conventionally, it has been known to provide tear lines and the like in order to cut the waist
固定部F1之腹側腰部周邊部20與結合部5的固定,可使用常見的固定方法。例如,可用熱或超音波的溶接、接著劑等來固定。又,本實施形態之紙尿褲1的固定部F1是溶接部。如上述般,紙尿褲1的切斷引導部,是將腹側腰部周邊部20與結合部5予以溶接來接合固定的溶接部為佳。Common fixing methods can be used to fix the abdominal waist
圖9A,是針對紙尿褲1的切斷引導部來說明的圖。圖9B,是針對撕裂線之切斷引導部來說明的圖。圖9A,是圖5A之部分Y的擴大圖,圖9B,是一般的拋棄式紙尿褲的腹側腰部周邊部之設有撕裂線之部分的擴大圖。紙尿褲1的切斷引導部,是藉由溶接來固定。如上述般,作為以往的切斷引導部,已知有撕裂線等。如圖9B所示般,關於撕裂線M所成的切斷引導部,在設有撕裂線M之部分的肌膚側腰部周邊部20,會開有孔,或是纖維變得較少,故為容易破損的部分。因此,在紙尿褲1的製造過程或搬運時、穿著者等使用紙尿褲1時,會有違反穿著者等的意圖而不小心以切斷引導部撕破腹側腰部周邊部20之虞。對此,如圖9A所示般,溶接部,是將纖維予以融化來固定的部分,纖維的總量沒有減少。因此,溶接部所成的固定部F1作為切斷引導部來發揮功能,藉此在進行以切斷為目的之操作之際,可以進行切斷,並且在沒有切斷之意圖的情況,可減輕違反意圖而不小心以切斷引導部撕破腹側腰部周邊部20之虞。Fig. 9A is a diagram explaining the cutting guide portion of the
如圖5等所示般,在從腹側腰部周邊部20側觀看紙尿褲1時與固定部F1重疊的部分,在前後方向(厚度方向),腹側腰部周邊部20之中,最靠結合部5側之構件的融點,是比結合部5之中,最靠腹側腰部周邊部20側之構件的融點還低為佳。在紙尿褲1,腹側腰部周邊部20之中,最靠結合部5側的構件,是非肌膚側薄片22,結合部5之中,最靠腹側腰部周邊部20側的構件,是三層之中最靠肌膚側的不織布薄片。在藉由溶接來固定的固定部F1,由於是融點較低的材料比較容易融化,故融化的材料比較容易被切斷。因此,使腹側腰部周邊部20之最靠結合部5側之構件(非肌膚側薄片22)的融點,比結合部5之最靠腹側腰部周邊部20側之構件的融點還低,而更容易融化,藉此促進切斷引導部(固定部F1)之腹側腰部周邊部20側之構件(非肌膚側薄片22)的融化,可容易切斷腹側腰部周邊部20。As shown in FIG. 5 and others, when the
此外,不只是腹側腰部周邊部20之最靠結合部5側的構件(非肌膚側薄片22),還使構成腹側腰部周邊部20之其他構件(在本實施形態為肌膚側薄片21)的融點,比結合部5之最靠腹側腰部周邊部20側的融點還低較佳。比起結合部5的構件,容易促進腹側腰部周邊部20全體的融化,故更容易切斷腹側腰部周邊部20。In addition, not only the member (non-skin-side sheet 22) of the abdominal waist
又,作為以固定部F1來溶接(融化)之腹側腰部周邊部20的肌膚側薄片21、非肌膚側薄片22等之構件、結合部5之構件,可使用由聚酯、聚乙烯、聚丙烯、聚對苯二甲酸乙二醇酯等所成的不織布薄片或薄膜薄片。In addition, as the members of the skin-
作為以固定部F1為切斷引導部來切斷腹側腰部周邊部20的方法,例如上述般,有著將結合部5與腹側腰部周邊部20分別往左右方向的外側拉開藉此使腹側腰部周邊部20分離的方法、將結合部5與腹側腰部周邊部20分別往相反方向扭扯來撕開的方法等。As a method of cutting the abdominal waist
在以切斷引導部來切斷腹側腰部周邊部20之際,從前後方向的腹側腰部周邊部20側來觀看紙尿褲1時,從結合部5的前端部側鄰接於固定部F1的鄰接區域中,在比較結合部5之中每單位面積之重量最小的部分與腹側腰部周邊部20之中每單位面積之重量最大的部分時,結合部5之中每單位面積之重量最小的部分比較大為佳。圖10A及圖10B,是針對切斷引導部的切斷來說明的圖。圖10A,是圖5A之部分Y的擴大圖。圖10A及圖10B,是用來說明切斷引導部的示意圖,並不一定具有與其他圖或實際的產品之尺寸等的整合性。在圖10A及圖10B,將每單位面積之重量較大之結合部5的厚度予以表示成較厚,將每單位面積之重量較小之腹側腰部周邊部20的厚度表示成較薄。When the abdominal waist
在紙尿褲1,如圖10A所示般,從以固定部F1來固定每單位面積之重量較大的結合部5與每單位面積之重量較小的腹側腰部周邊部20的狀態,來如圖10B所示般,將結合部5與腹側腰部周邊部20分別朝向左右方向的外側拉開的話,撕開的力會集中在固定部F1,而在固定部F1之左右方向之另一方側的端部CE使腹側腰部周邊部20如被撕開地切斷。此時,從腹側腰部周邊部20側觀看時,在從結合部5的前端部側鄰接於固定部F1的鄰接區域,使結合部5之每單位面積的重量比腹側腰部周邊部20之每單位面積的重量還大,藉此比起結合部5之每單位面積的重量比腹側腰部周邊部20之每單位面積的重量還小的情況,容易使腹側腰部周邊部20如被撕開地切斷,每單位面積之重量較大的結合部5,容易維持固定於固定部F1的狀態。如上述般,容易切斷的不是結合部5而是腹側腰部周邊部20,藉此使結合部5卡合於被切斷及分離的腹側腰部周邊部20,藉此可形成腰部周邊開口,可成為紙尿褲1。In the
腹側腰部周邊部20與結合部5之每單位面積的重量,例如,是分別從各構件將單位面積(例如10mm×10mm的正方形)作為鄰接區域來切出樣本,測量各樣本的重量藉此可進行比較。又,本實施形態的紙尿褲1,在腹側腰部周邊部20的上端部,是使肌膚側薄片21等之構件折返,故折返之構件最多重疊的部分會是腹側腰部周邊部20之每單位面積之重量最大的部分,將該部分切出作為樣本。同樣地,在結合部5,在每單位面積之重量有部分地不同的情況,是將每單位面積之重量最大的部分切出作為樣本,並比較兩樣本的重量。又,作為鄰接區域,是指從固定部F1之左右方向之另一方側的端部CE往結合部5之前端部側的既定區域,在本實施形態為10mm×10mm的正方形,但只要是從固定部F1之左右方向之另一方側的端部CE鄰接於結合部5之前端部側的區域與腹側腰部周邊部20及結合部5的疊層等之構造為相同的話,該長度可任意設定。且,在從固定部F1之左右方向之另一方側的端部CE鄰接於結合部5之前端部側的區域與腹側腰部周邊部20及結合部5的疊層等之構造為相同的情況時,每單位面積之重量的比較,是將任意部分切出作為樣本亦可。The weight per unit area of the abdominal waist
此外,從前後方向的腹側腰部周邊部20側來觀看紙尿褲1時,從結合部5的前端部側鄰接於固定部F1的鄰接區域中,在比較結合部5之中每單位面積之重量最小的部分與腹側腰部周邊部20之中每單位面積之重量最大的部分時,結合部5之中每單位面積之重量最小的部分比較大為佳。In addition, when the
本實施形態之紙尿褲1的腹側腰部周邊部20,是使肌膚側薄片21與非肌膚側薄片22的薄片構件(腰部周邊薄片構件)重疊來形成,結合部5,是使不織布薄片、薄膜薄片、不織布薄片的三個薄片構件(結合部薄片構件)重疊來形成。紙尿褲1,如圖10A所示般,結合部5之結合部薄片構件(三層的薄片構件)之每單位面積的重量較大,腹側腰部周邊部20之腰部周邊薄片構件(肌膚側薄片21與非肌膚側薄片22)之每單位面積的重量較小。從以固定部F1來固定該結合部5與腹側腰部周邊部20的狀態,來如圖10B所示般,將結合部5與腹側腰部周邊部20分別朝向左右方向的外側拉開的話,撕開的力會集中在固定部F1,而在固定部F1之左右方向之另一方側的端部CE使腹側腰部周邊部20如被撕開地切斷。此時,從腹側腰部周邊部20側觀看時,在從結合部5的前端部側鄰接於固定部F1的鄰接區域,使結合部5之結合部薄片構件(三層的薄片構件)之每單位面積的重量,比腹側腰部周邊部20之腰部周邊薄片構件(肌膚側薄片21與非肌膚側薄片22)之每單位面積的重量還大,藉此比起結合部5之結合部薄片構件(三層的薄片構件)之每單位面積的重量比腹側腰部周邊部20之腰部周邊薄片構件(肌膚側薄片21與非肌膚側薄片22)之每單位面積的重量還小的情況,容易使腹側腰部周邊部20如被撕開地切斷,結合部5,容易維持固定於固定部F1的狀態。如上述般,容易切斷的不是結合部5而是腹側腰部周邊部20,藉此使結合部5卡合於被切斷及分離的腹側腰部周邊部20,藉此可形成腰部周邊開口,可成為紙尿褲1。The abdominal waist
腹側腰部周邊部20與結合部5之每單位面積的重量,例如,是分別從各構件將單位面積(例如10mm×10mm的正方形)作為鄰接區域來切出樣本,浸泡於甲苯等來分離疊層的各薄片構件,分別採取成為對象的腰部周邊薄片構件(肌膚側薄片21、非肌膚側薄片22)、及結合部薄片構件(三層的薄片)。又,在各薄片構件殘留接著劑等的情況時,是以甲苯等全部去除。之後,使各薄片構件在常溫乾燥24小時之後,測量各薄片構件的重量,算出各樣本之分離後的薄片構件之和,藉此可進行比較。也就是說,在腹側腰部周邊部20與結合部5,測量將接合各薄片構件的接著劑(熱熔膠接著劑)予以去除的重量來進行比較。又,本實施形態的紙尿褲1,在腹側腰部周邊部20的上端部,是使肌膚側薄片21等之構件折返,故折返之構件最多重疊的部分會是腹側腰部周邊部20之腰部周邊薄片構件之每單位面積之重量最大的部分,將該部分切出作為樣本。同樣地,在結合部5,在每單位面積之重量有部分地不同的情況,是將結合部薄片構件之每單位面積之重量最大的部分切出作為樣本,並比較從兩樣本去除接著劑的重量。又,作為鄰接區域,是指從固定部F1之左右方向之另一方側的端部CE往結合部5之前端部側的既定區域,在本實施形態為10mm×10mm的正方形,但只要是從固定部F1之左右方向之另一方側的端部CE鄰接於結合部5之前端部側的區域與腹側腰部周邊部20及結合部5的疊層等之構造為相同的話,該長度可任意設定。且,在從固定部F1之左右方向之另一方側的端部CE鄰接於結合部5之前端部側的區域與腹側腰部周邊部20及結合部5的疊層等之構造為相同的情況時,每單位面積之重量的比較,是將任意部分切出作為樣本亦可。The weight per unit area of the abdominal waist
且,固定部F1全部為切斷引導部為佳。比起固定部F1的一部分為切斷引導部的情況,容易沿著固定部F1進行腹側腰部周邊部20的切斷。Furthermore, it is preferable that the entire fixed portion F1 is a cutting guide portion. Compared with a case where a part of the fixed portion F1 is a cutting guide portion, it is easier to cut the abdominal waist
本實施形態的紙尿褲1,在腹側腰部周邊部20設有切斷引導部(固定部F1)。設在腹側腰部周邊部20的切斷引導部,是在上下方向從腹側腰部周邊部20的上端連續到下端為佳。也就是說,切斷引導部亦即固定部F1,是從腹側腰部周邊部20的上端連續到下端為佳。使切斷引導部從腹側腰部周邊部20的上端連續到下端,藉此比起切斷引導部不連接的情況,能沿著切斷引導部來切斷腹側腰部周邊部20,容易完全分離。The
如圖8所示般,切斷引導部(固定部F1)之中,最前端部側的端部K,是切斷引導起點K。切斷引導起點K,在為了以切斷引導部來切斷腹側腰部周邊部20,而對腹側腰部周邊部20與結合部5施加力時,是力最容易集中的部分,也是切斷最容易先開始的部分。而且,如圖8所示般,切斷引導部,具有:從最前端部側的端部K,朝向基端部側,且於上下方向傾斜的傾斜部fa1、fb1為佳。藉此,穿著者等將腹側腰部周邊部20與結合部5分別拉開時的力,首先,可容易集中在切斷引導起點K,且容易將該力從切斷引導起點K傳到傾斜部fa1、fb1,而容易將腹側腰部周邊部20切斷成沿著切斷引導部的形狀。As shown in FIG. 8 , the end K on the frontmost side of the cutting guide portion (fixed portion F1 ) is the cutting guide starting point K. The cutting guide starting point K is the part where the force is most likely to concentrate when a force is applied to the abdominal waist
又,傾斜部fa1、fb1的「傾斜」,是指對於上下方向及左右方向具有傾斜,不限於紙尿褲1那般直線狀的傾斜部fa1、fb1,具備彎曲的部分亦可。In addition, the "incline" of the inclined portions fa1 and fb1 means having an inclination in the up-down direction and the left-right direction, and is not limited to the linear inclined portions fa1 and fb1 like the
且,如圖8所示般,切斷引導部,具有上側傾斜部fa1與下側傾斜部fb1為佳。上側傾斜部fa1,是從最前端部側的端部K(切斷引導起點)朝向上側且基端部側來傾斜的傾斜部,下側傾斜部fb1,是從最前端部側的端部K(切斷引導起點)朝向下側且基端部側來傾斜的傾斜部。藉此,為了以切斷引導部來切斷腹側腰部周邊部20,而施加於腹側腰部周邊部20與結合部5的力,首先,會容易集中在切斷引導起點K,且容易將集中在切斷引導起點K的力傳到上側傾斜部fa1與下側傾斜部fb1,藉此容易進行腹側腰部周邊部20的切斷。Moreover, as shown in FIG. 8 , the cutting guide portion preferably has an upper inclined portion fa1 and a lower inclined portion fb1 . The upper inclined portion fa1 is an inclined portion inclined from the end K on the frontmost end side (cutting guide starting point) toward the upper side and the base end side, and the lower inclined portion fb1 is an inclined portion inclined from the end K on the frontmost end side (Cutting guide starting point) An inclined portion inclined toward the lower side and the base end side. Thereby, in order to cut the abdominal waist
此外,上側傾斜部fa1與下側傾斜部fb1所夾的角度之中,左右方向之基端部側的角度θ為鈍角(比90度還大,比180度還小的角度)較佳。藉此,從切斷引導起點K對上側傾斜部fa1與下側傾斜部fb1施加的力容易傳遞,容易使腹側腰部周邊部20切斷,且比起θ為銳角的情況,可使切斷引導部(固定部F1)之左右方向的長度變短。In addition, among the angles between the upper inclined portion fa1 and the lower inclined portion fb1, it is preferable that the angle θ on the base end side in the left-right direction is an obtuse angle (an angle larger than 90 degrees and smaller than 180 degrees). Thereby, the force applied to the upper slope part fa1 and the lower slope part fb1 from the cutting guide starting point K is easily transmitted, and the abdominal waist
如圖7所示般,在左右方向,切斷引導起點K,設在比吸收性芯11A還靠一方側為佳。吸收性芯11A,是紙尿褲1之中具有厚度的部分,為剛度較高的部分,故為不易切斷腹側腰部周邊部20的部分。因此,在左右方向,在比吸收性芯11A還靠一方側設置切斷引導起點K,藉此可提升腹側腰部周邊部20的切斷容易度。As shown in FIG. 7 , the cutting guide starting point K is preferably located on one side of the absorptive core 11A in the left-right direction. The absorptive core 11A is a thick portion of the
關於在腹側腰部周邊部20以固定部F1來固定的結合部5,是在左右方向,使切斷引導部,設在接合部2a與吸收性芯11A之間為佳。也就是說,在左右方向,固定部F1,設在接合部2a與吸收性芯11A之間為佳。吸收性芯11A具有厚度,剛度較高,為不易切斷腹側腰部周邊部20的部分,故在左右方向,將切斷引導部設在接合部2a與吸收性芯11A之間,藉此可提升腹側腰部周邊部20的切斷容易度。Regarding the joining
且,如圖4等所示般,在上下方向,使切斷引導起點K與卡合部51重疊為佳。如圖6A及圖6B所示般,在沿著切斷引導部來切斷腹側腰部周邊部20的情況時,較多把持結合部5的卡合部51。於是,在上下方向,使切斷引導起點K與卡合部51重疊,藉此在切斷之際,容易將施加於結合部5的力傳到切斷引導起點K,容易進行沿著切斷引導部之腹側腰部周邊部20的切斷。Moreover, as shown in FIG. 4 etc., it is preferable that the cutting guide starting point K overlaps with the engaging
又,如圖4所示般,在左右方向,從切斷引導起點K到結合部5之前端部側之端部(另一方側之端部)為止的長度H,為50mm以上為佳。如圖6A及圖6B所示般,在抓住腹側腰部周邊部20與結合部5來分別朝向左右方向的外側拉開藉此切斷腹側腰部周邊部20之際,在左右方向之切斷引導起點K到結合部5之前端部側的端部為止的長度未達50mm的情況,會難以用手抓住結合部5,或在拉開之際難以施加力。於是,使左右方向之切斷引導起點K到結合部5之前端部側的端部為止的長度H為50mm以上,藉此使穿著者等容易進行腹側腰部周邊部20的切斷。In addition, as shown in FIG. 4 , the length H in the left-right direction from the cutting guide starting point K to the end on the front end side of the coupling portion 5 (the other end) is preferably 50 mm or more. As shown in FIGS. 6A and 6B , when the abdominal waist
具有用來輔助結合部5與腹側腰部周邊部20之固定的輔助固定部F2為佳。該輔助固定部F2,是在比切斷引導部(固定部F1)還靠結合部5的基端部側(左右方向的一方側),於上下方向間隔地配置較佳。如圖8等所示般,在比切斷引導部還基端部側,具有使複數個大致橢圓形狀沿著切斷引導部來間隔配置的輔助固定部F2。輔助固定部F2,與固定部F1同樣地,是將結合部與腹側腰部周邊部20予以溶接的部分。藉由具備輔助固定部F2,來強化固定部F1所致之結合部5與腹側腰部周邊部20的固定,並可藉由間隔地配置的輔助固定部F2,來減輕以輔助固定部F2為起點切斷腹側腰部周邊部20之虞。特別是,藉由間隔地配置輔助固定部F2,在結合部5從基端部側的端部朝向前端部側施加有力的情況,可減輕以輔助固定部F2之基端部側的端部為邊界來切斷腹側腰部周邊部20之虞。It is preferable to have an auxiliary fixing part F2 for assisting in fixing the
此外,紙尿褲1,在固定部F1與輔助固定部F2之間,具備從固定部F1往基端部側突出的複數個突出固定部。複數個突出固定部,是於上下方向間隔地配置。該突出固定部,與輔助固定部F2同樣地,強化固定部F1所致之結合部5與腹側腰部周邊部20的固定,並可藉由間隔地配置的突出固定部,來減輕以突出固定部為起點切斷腹側腰部周邊部20之虞。Furthermore, the
且,在設有固定部F1的腹側腰部周邊部20,從切斷引導部朝向結合部5之前端部側既定距離的部分,是腹側腰部周邊部20不會往左右方向伸縮的非伸縮區域為佳。在穿著者等為了切斷腹側腰部周邊部20而抓住結合部5來拉開時,能夠減輕因腹側腰部周邊部20本身的伸長而緩衝所施加之力之虞,使拉開結合部5時的力容易施加於切斷引導部(固定部F1),藉此容易進行拉開結合部5所致之腹側腰部周邊部20的切斷。Furthermore, in the abdominal waist
紙尿褲1的腹側腰部周邊部20,如圖4及圖7所示般,具備往左右方向伸縮的伸縮構件23,且具備往左右方向伸縮的伸縮區域S與不往左右方向伸縮的非伸縮區域N。腹側腰部周邊部20的伸縮區域S,是指伸縮構件23可伸縮的區域。具體來說,在左右方向,中央部及從中央部到結合部5之一方側的側端為止之間的區域為非伸縮區域N。伸縮區域S,在左右方向具有:設在一方側的一方側伸縮區域Sa、設在另一方側的另一方側伸縮區域Sb,從一方側的接合部2a到結合部5之一方側的側端為止的區域為一方側伸縮區域Sa,從另一方側的接合部2b到中央部為止的區域為另一方側伸縮區域Sb。也就是說,從腹側腰部周邊部20觀看時,與結合部5重疊之腹側腰部周邊部20的部分為非伸縮區域N。因此,藉由從切斷引導部(固定部F1)朝向結合部5之前端部側來設置的非伸縮區域N,容易將施加於結合部5的力予以施加於切斷引導部。As shown in FIGS. 4 and 7 , the abdominal waist
又,「從切斷引導部朝向結合部5之前端部側既定距離的部分」之既定距離,可設定成任意長度。但是,在左右方向,從前端部側(另一方側)鄰接於切斷引導部(固定部F1)的非伸縮區域N之長度越長,則越能減輕施加於結合部5的力因伸縮而被緩衝的情況,容易施加於切斷引導部,故本實施形態之紙尿褲1之非伸縮區域N的「既定距離」,是比從切斷引導部到結合部5之前端部為止的距離還長者。In addition, the predetermined distance of "the portion from the cutting guide portion to the front end side of the
作為腹側腰部周邊部20的非伸縮區域N,例如藉由不配置伸縮構件23而可實現。且,在腹側腰部周邊部20之全域配置伸縮構件23或伸縮薄片等之伸縮構件的情況也是,在相當於非伸縮區域N的位置,設置複數個溶接部,藉此使腹側腰部周邊部20之所期望的位置成為非伸縮亦可。The non-elastic region N of the abdominal waist
且,腹側腰部周邊部20不只是具備非伸縮區域N,而是使結合部5本身成為不伸縮較佳。藉此,可以減輕將結合部5與腹側腰部周邊部20予以互相往外側拉開的力被結合部5的伸縮給緩衝的情況,而容易對切斷引導部施加力,故容易進行腹側腰部周邊部20的切斷。Furthermore, it is preferable that the abdominal waist
此外,關於腹側腰部周邊部20,左右方向之切斷引導部到吸收性芯11A之一方側(結合部5的基端部側)的側端為止的區域,是不往左右方向伸縮(非伸縮區域N)較佳。藉此,可以減輕對結合部5施加的力因伸縮而緩衝的情況,容易施加於切斷引導部,故容易以結合部5的操作來進行腹側腰部周邊部20的切斷。In addition, regarding the abdominal waist
關於設有固定部F1的腹側腰部周邊部20,是在從切斷引導部朝向結合部5之前端部側既定距離的部分,塗布有接著劑為佳。一般來說,在腹側腰部周邊部20塗布有接著劑的部分,比沒有塗布接著劑的部分還高剛度。因此,腹側腰部周邊部20之中,在從切斷引導部朝向結合部5之前端部側既定距離的部分塗布接著劑,藉此提高既定距離之部分的剛度,在穿著者等為了切斷腹側腰部周邊部20而抓住結合部5來拉開時的力,容易施加於切斷引導部(固定部F1),藉此容易進行拉開結合部5所致之腹側腰部周邊部20的切斷。The abdominal waist
在腹側腰部周邊部20塗布的接著劑,是將肌膚側薄片21或非肌膚側薄片22等之各構件予以固定的熱熔膠接著劑等之接著劑亦可,不是以互相接著構件為目的來塗布的接著劑亦可。且,塗布接著劑的「既定距離」,可設定成任意長度。但是,從左右方向之前端部側(另一方側)鄰接於切斷引導部(固定部F1)之有塗布接著部的區域越長(廣),則越容易將施加於結合部5的力予以施加於切斷引導部,故本實施形態之紙尿褲1之塗布接著部的「既定距離」,是比從切斷引導部到結合部5之前端部為止的距離還長者。The adhesive applied to the abdominal waist

===關於紙尿褲1的穿著方法===
紙尿褲1,可用複數種方法來穿著。
例如,作為一般的內褲型紙尿褲(參照圖14),是讓穿著者的腳從腰部周邊開口部BH進入腿部周邊開口部LH,以將腰部周邊部20、30包圍穿著者之腰部周邊的方式拉起藉此可成為穿著狀態。
===About how to wear
且,如上述般穿著成內褲型的拋棄式紙尿褲之後,以切斷引導部(後述)來切斷腹側腰部周邊部20,將結合部5的卡合部51卡合於腹側腰部周邊部20,形成腰部周邊開口藉此可成為穿著狀態。藉此,可調整卡合部51的卡合位置,容易密貼於穿著者的腰部周邊。Furthermore, after wearing the panty-type disposable diaper as described above, the abdominal waist
此外,事先以切斷引導部來切斷腹側腰部周邊部20,使左右方向的一方側為所謂黏貼型紙尿褲的形態(沒有形成腿部周邊開口部LH的狀態),使左右方向的另一方側為內褲型紙尿褲的形態(形成有腿部周邊開口部LH的狀態)亦可穿著。In addition, the abdominal waist
首先,以切斷引導部來切斷腹側腰部周邊部20,讓穿著者之另一方側的腳(在紙尿褲1是穿著者的右腳)通過左右方向的另一方側(內褲型紙尿褲的形態)的腿部周邊開口部LH,之後將紙尿褲1拉起到穿著者的股間部,之後,以密貼於穿著者之腰部周邊的方式,使結合部5的卡合部51卡合於腹側腰部周邊部20,而形成腰部周邊開口,藉此成為穿著狀態。First, the abdominal waist
藉由如此地穿著,即使對於例如腳會亂動而難以讓雙腳通過內褲型之拋棄式紙尿褲之兩側之腿部周邊開口部LH的乳幼兒,只要可讓穿著者的單腳通過腿部周邊開口部LH的話,之後以結合部5(卡合部51)來卡合,藉此可容易成為穿著狀態。且,穿著者本身,在進行穿著紙尿褲1的情況,會有難以在廁所等穿著一般的黏貼型紙尿褲(在左右方向的兩側具備膠帶的紙尿褲)的情況,但使左右方向的一方側為內褲型的形態,使另一方側為具備結合部5(黏貼型)的形態,藉此容易穿著,且容易調整腰部周邊的密貼性。By wearing it in this way, for example, even for infants whose feet move around and it is difficult to pass the legs through the leg peripheral openings LH on both sides of the panty-type disposable diaper, as long as the wearer can pass one leg through the legs. The peripheral opening LH is then engaged with the coupling portion 5 (engagement portion 51), thereby making it easy to put it into a wearing state. Moreover, when the wearer himself wears the
又,將使用後的紙尿褲1從身體卸下之際,以切斷引導部來分離腹側腰部周邊部20,從穿著者的身體卸下紙尿褲1之左右方向的一方側,將另一方側的腳從左右方向之另一方側的腿部周邊開口部LH抽出,藉此可將紙尿褲1從穿著者的身體卸下。Furthermore, when the used
===關於腹側腰部周邊部20的切斷===
針對腹側腰部周邊部20的切斷,使用圖18及圖19來說明。圖18,是針對腹側腰部周邊部20的分離及腰部周邊開口的形成來說明的圖。圖19,是針對腹側腰部周邊部20的切斷動作來說明的圖。圖18,是說明圖17中的A-A箭頭視角之剖面之構造的圖。又,圖18及圖19是示意圖,尺寸等並不一定正確。
===About cutting off the abdominal waist
圖18A,是圖14等所示之內褲型之狀態的紙尿褲1。也就是說,腹側腰部周邊部20並未切斷,而是形成使腹側腰部周邊部20與背側腰部周邊部30透過接合部2a、2b來連接的腰部周邊開口。從圖18A所示之狀態,將抓住結合部5的前端部並朝向非肌膚側拉起的狀態,示於圖18B及圖19A。Fig. 18A shows the
然後,如圖19A所示般,以單手抓住腰部周邊部20,以另一隻手抓住結合部5,分別朝向左右方向的外側拉開,藉此如圖18C及圖19B所示般,腹側腰部周邊部20會沿著切斷引導部被切斷,使左右方向的一方側與另一方側分離。「切斷引導部」,是指在切斷腹側腰部周邊部20之至少一部分之際的引導部。紙尿褲1中,將腹側腰部周邊部20與結合部5予以固定的固定部F1,是作為切斷引導部來發揮功能。具體來說,如圖19A所示般,在分別抓著腹側腰部周邊部20與結合部5的狀態往左右方向拉開的話,首先,拉動的力會集中在切斷引導部(固定部F1)之中位於最前端部側的前端部側之端部亦即切斷引導起點K,之後,沿著從切斷引導部的切斷引導起點K朝向上側且基端部側來傾斜的傾斜部與從切斷引導起點K朝向下側且基端部側來傾斜的傾斜部來傳遞力。然後,以固定部F1之左右方向之另一方側的端部CE為邊界,使腹側腰部周邊部20被切斷,腹側腰部周邊部20,被分離成不具備結合部5的一方側之部分與具備結合部5的另一方側之部分。Then, as shown in FIG. 19A , grasp the waist
之後,因應必要,如圖18D所示般,將結合部5的卡合部51卡合於腹側腰部周邊部20的被卡合部25,藉此形成紙尿褲1的腰部周邊開口。在將卡合部51卡合於被卡合部25的狀態下,使分離之腹側腰部周邊部之左右方向的一方側部分與另一方側部分,在前後方向(厚度方向)重疊地將卡合部51卡合於被卡合部25亦可,使分離之腹側腰部周邊部之左右方向的一方側部分與另一方側部分,在前後方向(厚度方向)不重疊地將卡合部51卡合於被卡合部25亦可。藉由調整卡合部51的卡合位置,而可調整紙尿褲1之腰部周邊開口的大小。Thereafter, if necessary, as shown in FIG. 18D , the engaging
===關於切斷引導部===
如上述般,紙尿褲1,是使腹側腰部周邊部20與背側腰部周邊部30之左右方向的兩側端部,分別以接合部2a、2b來接合。且,結合部5的基端部,連接於腹側腰部周邊部20,在結合部5的前端部,具有可分離地卡合於腹側腰部周邊部20之非肌膚側面的卡合部51。而且,腹側腰部周邊部20,具有切斷引導部。切斷引導部,設在與設在左右方向之兩側端部的接合部2a、2b不同的位置,且腹側腰部周邊部20之至少一部分為被融化的融化部F1。
