In order to solve this problem, the shorts-type disposable wearing article of the present invention has a front body and a back body, and has holes formed on the center side in the width direction of the side sealing portion 21 from the waist opening to the leg opening. 21 is formed by joining the two side parts of the front body and the two side parts of the rear body respectively, and the aforementioned eyelets are formed by repeating units having the first eyelets 61 and the second eyelets 62 in the longitudinal direction. The first eyelet 61 extends in the longitudinal direction, and the second eyelet 62 extends obliquely from the end of the first eyelet toward the side sealing portion.
Description
本發明關於一種短褲型(褲型)拋棄式穿著用物品。The present invention relates to a shorts-type (trouser-type) disposable wearing article.
短褲型拋棄式尿布、短褲型拋棄式生理用衛生棉、短褲型拋棄式尿布兜(diaper cover)等短褲型拋棄式穿著用物品，具有將前身的兩側部和後身的兩側部分別地接合而形成的側封部，且藉由此側封部的形成而事先地形成腰開口和腿開口。Shorts-type disposable diapers, shorts-type disposable sanitary napkins, shorts-type disposable diaper covers, and other shorts-type disposable wearing articles have the function of separately separating the two sides of the front body and the two sides of the back body. The side sealing parts are formed by joining, and the waist opening and the leg opening are formed in advance by the formation of the side sealing parts.
在這種短褲型拋棄式尿布中，當***後等要脫去尿布時，能夠在側封部將前身和後身加以拉扯並剝開，以實行將尿布自身體脫除。因此，在側封部中，不僅要謀求穿著中不會破裂的剝離強度，也要謀求使用後容易剝開。In this pants-type disposable diaper, when the diaper needs to be taken off after excretion, etc., the front body and back body can be pulled and peeled off at the side seals to remove the diaper from the body. Therefore, the side seals must not only have a peeling strength that does not break during wearing, but also must be easy to peel off after use.
用於容易在側封部將前身和後身加以拉扯並剝開的一種手法，是對於側封部的接合圖案的改良，但是在僅藉由對於側封部的接合圖案的改良就要改良成容易拉扯並剝開的情況下，仍有許多困難。特別是，要確保對於側封部要求的剝離強度，同時使即便是力量弱的高齡者等也可容易進行剝離是困難的。One method for making it easier to pull and peel the front and back parts at the side seal is to improve the joint pattern of the side seal, but there are still many difficulties in improving the joint pattern of the side seal to make it easier to pull and peel. In particular, it is difficult to ensure the required peeling strength for the side seal while making it easy for even the elderly with weak strength to peel.
作為解決此問題之一種手法(例如，參照專利文獻1、2)，提案有一種不是對於側封部的接合圖案進行改良，而是在前身或後身中的比側封部更靠寬度方向的中央側，自腰開口朝向腿開口地形成孔眼(perforation)的手法。此時，不會影響側封部的剝離強度且使前身與後身的分離變得容易。As a method to solve this problem (for example, refer to Patent Documents 1 and 2), it is proposed that instead of improving the joint pattern of the side seals, the joint pattern of the front body or the rear body is further in the width direction than the side seals. On the center side, perforations are made from the waist opening to the leg opening. In this case, the peeling strength of the side seal portion is not affected and the separation of the front body and the back body becomes easy.
然而，僅單純地在前身或後身中設置孔眼，在切離孔眼的途中，可能會發生朝向寬度方向的中央側撕開之「橫裂」。However, if the eyelets are simply provided in the front body or the back body, a "transverse tear" that tears toward the center side in the width direction may occur on the way to remove the eyelets.
[先前技術文獻] (專利文獻) 專利文獻1：日本特開2018-139718號公報 專利文獻2：日本特開2018-187217號公報[Prior technical literature] (patent document) Patent Document 1: Japanese Patent Application Publication No. 2018-139718 Patent Document 2: Japanese Patent Application Publication No. 2018-187217
[發明所欲解決的問題] 於是，本發明主要所欲解決的問題，在於能夠藉由孔眼以比較弱的力量實行前身與後身的分離，並且不易發生橫裂。[Problem to be solved by the invention] Therefore, the main problem to be solved by the present invention is to be able to separate the front body and the rear body with a relatively weak force through the holes, and it is less likely to cause transverse cracks.
[解決問題的技術手段] 解決了上述問題之短褲型拋棄式穿著用物品如下述。 ＜第一形態＞ 一種短褲型拋棄式穿著用物品，其特徵在於，具備： 前身和後身； 側封部，其將前述前身的兩側部和前述後身的兩側部加以分別地接合而形成； 腰圍部，其藉由前述側封部而連續成筒狀； 腰開口，其是前述腰圍部的腰側的開口；及， 左右一對的腿開口，其被形成在比前述腰圍部更靠腿側； 其中，在前述前身和前述後身的至少一方中的比前述側封部更靠寬度方向的中央側，自前述腰開口朝向前述腿開口地形成孔眼， 前述孔眼是將具有第一孔眼和第二孔眼之單元在縱方向上反復地設置而成，該第一孔眼在縱方向上延伸，該第二孔眼自此第一孔眼的端部往前述側封部側斜向地延伸， 前述第二孔眼，具有上方向第二孔眼和下方向第二孔眼的至少一方，該上方向第二孔眼往斜上方向延伸，該下方向第二孔眼往斜下方向延伸。[Technical means to solve problems] The shorts-type disposable wearing articles that solve the above problems are as follows. ＜First form＞ A shorts-type disposable wearing article is characterized by: Antecedent and posterior body; Side sealing parts formed by separately joining the two side parts of the front body and the two side parts of the rear body; The waist part is continuously formed into a tubular shape by the aforementioned side sealing parts; Waist opening, which is the opening on the waist side of the aforementioned girdle portion; and, A pair of left and right leg openings formed closer to the leg side than the aforementioned waistline; Wherein, at least one of the front body and the back body has an eyelet formed on the center side in the width direction of the side sealing portion from the waist opening toward the leg opening, The aforementioned eyelets are formed by repeatedly arranging units with first eyelets and second eyelets in the longitudinal direction. The first eyelet extends in the longitudinal direction, and the second eyelet is sealed from the end of the first eyelet to the aforementioned side. extends diagonally from side to side, The second eyelet has at least one of an upward second eyelet extending obliquely upward and a downward second eyelet extending obliquely downward.
(作用效果) 自前述腰開口朝向前述腿開口，自上往下、或自下往上，使前述孔眼連續而容易切離，能夠在切離的途中使前身和後身的橫裂不易發生，且容易自穿著者脫下前述短褲型拋棄式穿著用物品。 因為具有沿著前身、後身的側封部之前述孔眼，所以即便是任意處都可以進行切離，也可以一處接著一處地切離。 較佳為前述第一孔眼的端部，與往前述側封部側斜向延伸的第二孔眼的起始點連在一起。前述第一孔眼與前述第二孔眼連成一串，藉此切離可自前述第一孔眼往前述第二孔眼連續地發生。 又，前述側封部在前述第二孔眼的延長線上，所以即便在萬一前述第二孔眼的端部中的切離沒有回到前述第一孔眼的情況，也可以沿著前述側封部使往腿開口的切離繼續前進。 本形態是不易發生橫裂的最起碼的形態。(Effect) From the aforementioned waist opening to the aforementioned leg opening, from top to bottom or from bottom to top, the aforementioned eyelets are continuous and easy to cut apart, which can prevent the transverse cracks of the front body and the back body from easily occurring during the cutting process, and make it easy to wear by oneself. The person takes off the aforementioned shorts-type disposable clothing item. Since it has the aforementioned holes along the side seals of the front body and rear body, it can be cut off at any point, or one place after another. Preferably, the end of the first eyelet is connected to the starting point of the second eyelet that extends obliquely toward the side sealing portion. The aforementioned first eyelet and the aforementioned second eyelet are connected in a series, whereby the cutting can occur continuously from the aforementioned first eyelet to the aforementioned second eyelet. Furthermore, the side sealing portion is on the extension line of the second eyelet, so even if the end portion of the second eyelet is not cut back to the first eyelet, it can be made along the side sealing portion. Continue cutting toward the leg opening. This form is the minimum form that is less likely to cause transverse cracks.
＜第二形態＞ 如前述第一形態記載之短褲型穿著用物品，其中，在縱方向反復地排列的前述孔眼的單元之間，具有前述第二孔眼，該第二孔眼是端部往反向下側折返並延伸的前述下方向第二孔眼。＜Second form＞ The shorts-type wearing article according to the first aspect, wherein the second eyelet is provided between the units of the eyelets that are repeatedly arranged in the longitudinal direction, and the second eyelet has an end portion that is folded back and extended toward the opposite lower side. of the aforementioned lower part toward the second eyelet.
(作用效果) 分離的力量藉由前述折返而從前述單元中存在的孔眼的前述第二孔眼往在縱方向連續的下個單元的孔眼的起始點被誘導，所以可進行連續的孔眼的切離，藉此能夠使切離途中不易發生前身和後身的橫裂，且容易自穿著者脫下前述短褲型拋棄式穿著用物品。 藉由前述折返，使在前述第二孔眼產生的力量，半強制地回到往前述第一孔眼的縱方向，所以相較於前述第一形態可以通過前述第二孔眼使往縱方向的切離更順利地繼續前進。(Effect) The force of separation is induced by the aforementioned folding from the second eyelet of the eyelet existing in the aforementioned unit to the starting point of the eyelet of the next unit that is continuous in the longitudinal direction, so that continuous eyelet cutting can be performed. It is possible to prevent transverse tearing of the front body and the back body during the cutting process, and the shorts-type disposable wearing article can be easily taken off by the wearer. By the aforementioned turning back, the force generated in the aforementioned second eyelet is semi-forcibly returned to the longitudinal direction of the aforementioned first eyelet. Therefore, compared with the aforementioned first form, the longitudinal direction can be cut through the aforementioned second eyelet. Move on more smoothly.
＜第三形態＞ 如前述第一形態記載之短褲型穿著用物品，其中，在縱方向反復地排列的前述孔眼的單元之間，具有前述第二孔眼，該第二孔眼是端部往反向上側折返並延伸的前述上方向第二孔眼。＜Third form＞ The shorts-type wearing article according to the first aspect, wherein the second eyelet is provided between the units of the eyelets that are repeatedly arranged in the longitudinal direction, and the end of the second eyelet is folded back and extended to the opposite upper side. The aforementioned upward direction is the second eyelet.
(作用效果) 分離的力量藉由前述折返而從前述單元中存在的孔眼的前述第二孔眼往在縱方向連續的下個單元的孔眼的起始點被誘導，所以可進行連續的孔眼的切離，藉此能夠使切離途中不易發生前身和後身的橫裂，且容易自穿著者脫下前述短褲型拋棄式穿著用物品。 藉由前述折返，使在前述第二孔眼產生的力量，半強制地回到往前述第一孔眼的縱方向，所以相較於前述第一形態可以通過前述第二孔眼使往縱方向的切離更順利地繼續前進。 在前述第二形態中，切離是在縱方向自上往下繼續前進，但是在本形態中，切離是自下往上繼續前進。(Effect) The force of separation is induced by the aforementioned folding from the second eyelet of the eyelet existing in the aforementioned unit to the starting point of the eyelet of the next unit that is continuous in the longitudinal direction, so that continuous eyelet cutting can be performed. It is possible to prevent transverse tearing of the front body and the back body during the cutting process, and the shorts-type disposable wearing article can be easily taken off by the wearer. By the aforementioned turning back, the force generated in the aforementioned second eyelet is semi-forcibly returned to the longitudinal direction of the aforementioned first eyelet. Therefore, compared with the aforementioned first form, the longitudinal direction can be cut through the aforementioned second eyelet. Move on more smoothly. In the aforementioned second form, the separation proceeds from top to bottom in the longitudinal direction, but in this form, the separation proceeds from bottom to top.
＜第四形態＞ 如前述第一形態或第二形態記載之短褲型穿著用物品，其中，在縱方向反復排列的前述孔眼的單元之間，在前述下方向第二孔眼的端部往反向下側折返的延長線上具有前述第一孔眼， 在前述上方向第二孔眼的延長線上具有前述下方向第二孔眼。＜Fourth Form＞ The pants-type wearing article according to the first aspect or the second aspect, wherein between the units of the eyelets repeatedly arranged in the longitudinal direction, an extension of the end of the second eyelet in the lower direction is folded back toward the opposite lower side. The line has the aforementioned first eyelet, The second downward hole is provided on an extension line of the second upward hole.
(作用效果) 在前述下方向第二孔眼的折返的延長線上存在有下個前述單元的前述第一孔眼，且在前述上方向第二孔眼的延長線上配置有上個前述單元的前述下方向第二孔眼。本形態是第一形態和第二形態的組合，因為前述單元之間距離窄且前述單元的起始點與終點靠近，所以容易產生在單元的孔眼間的誘導，使得切離容易沿著孔眼發生。 又，切離的方向，可以在自前述腰開口往前述腿開口之自上往下、或反向地自下往上的任一方進行切離。(Effect) The first eyelet of the next unit is located on the folded extension line of the second downward eyelet, and the second downward eyelet of the previous unit is arranged on the extension line of the second upper eyelet. This form is a combination of the first form and the second form. Because the distance between the aforementioned units is narrow and the starting point and end point of the aforementioned units are close, induction is easily generated between the holes of the units, making it easy for shearing to occur along the holes. . Moreover, the cutting direction may be from top to bottom from the waist opening to the leg opening, or vice versa, from bottom to top.
＜第五形態＞ 如前述第一形態至第四形態的任一形態記載之短褲型穿著用物品，其中，在自前述腰開口朝向前述腿開口的沒有前述第一孔眼的孔之處所，在前述第一孔眼的寬度方向的中央側的附近具有孔。＜Fifth Form＞ The shorts-type wearing article according to any one of the first to fourth aspects, wherein the width of the first eyelet is at a place where there is no hole of the first eyelet from the waist opening to the leg opening. There is a hole near the center side of the direction.

以下，一邊參照附圖一邊詳細地說明作為吸收性物品的一例之短褲型拋棄式尿布。Hereinafter, a pants-type disposable diaper as an example of the absorbent article will be described in detail with reference to the drawings.
圖1～圖6表示短褲型拋棄式尿布的一例。此短褲型拋棄式尿布(以下也簡稱為尿布)，具有：自前身F遍及至後身B之外裝體20；及，以自前身F遍及至後身B的方式被固定於外裝體20的內面之內裝體10；內裝體10，是由在透液性的頂片11與不透液性片12之間存在有吸收體13而構成。作成一種短褲型拋棄式尿布，當製造時，藉由熱熔黏接劑等接合手段來將內裝體10的背面接合於(圖2的點紋部分)外裝體20的內面(頂面)之後，將內裝體10和外裝體20在前身F與後身B的界線之前後方向(縱方向)的中央折疊，並藉由熱熔接或熱熔黏接劑等來將該兩側部彼此接合並形成側封部21，以形成腰開口和左右一對的腿開口。Figures 1 to 6 show an example of a pants-type disposable diaper. This pants-type disposable diaper (hereinafter also simply referred to as a diaper) has an outer body 20 extending from the front body F to the back body B; and is fixed to the outer body 20 in a manner extending from the front body F to the back body B. The inner surface of the inner body 10; the inner body 10 is composed of an absorbent body 13 between a liquid-permeable top sheet 11 and a liquid-impermeable sheet 12. To create a pants-type disposable diaper, during production, the back surface of the inner body 10 is joined (the dotted portion in Figure 2) to the inner surface (top surface) of the outer body 20 by joining means such as hot melt adhesive. ), the inner body 10 and the outer body 20 are folded in the center of the front-rear direction (longitudinal direction) of the boundary line between the front body F and the rear body B, and the two sides are joined by heat welding or hot-melt adhesive. The parts are joined to each other and form side sealing parts 21 to form a waist opening and a pair of left and right leg openings.
(內裝體的構造例) 內裝體10，如圖3所示，具有在頂片11與不透液性片12之間存在有吸收體13的構造，且藉由吸收體13來吸收保持透過了頂片11之***液。內裝體10的平面形狀沒有特別限定，一般會作成如圖示形態般的大致的長方形。(Structure example of interior body) As shown in FIG. 3 , the inner body 10 has a structure in which an absorbent body 13 is interposed between the top sheet 11 and the liquid-impermeable sheet 12 , and the absorbent body 13 absorbs and holds the excretion liquid that has passed through the top sheet 11 . . The planar shape of the inner body 10 is not particularly limited, but is generally formed into a roughly rectangular shape as shown in the figure.
作為覆蓋吸收體13的表面側(肌膚抵接面側)之頂片11，可適當地使用有孔或無孔的不織布、或者多孔性塑膠片。作為構成不織布的原材料纖維，除了設為聚乙烯或聚丙烯等烯烴系、聚酯系、以及聚醯胺系等合成纖維之外，還能夠設為人造絲或銅銨纖維等再生纖維、以及棉等天然纖維，能夠使用藉由水刺法、紡黏法、熱黏法、熔噴法、針刺法等適當的加工法所得到的不織布。這些加工法內，水刺法在富有柔軟性、懸垂性之點上優異，熱黏法在蓬鬆性、柔性之點上優異。當在頂片11上形成有多數個透孔時，成為可迅速地吸收尿等。圖示形態中，頂片11被捲入吸收體13的側緣部且延伸直到吸收體13的背面側。As the topsheet 11 covering the surface side (skin-contacting side) of the absorber 13, a porous or non-porous nonwoven fabric or a porous plastic sheet can be appropriately used. As raw material fibers constituting the nonwoven fabric, in addition to synthetic fibers such as olefin-based fibers such as polyethylene or polypropylene, polyester-based fibers, and polyamide-based fibers, they may also be recycled fibers such as rayon or cupro ammonium fibers, and cotton. Nonwoven fabrics obtained by appropriate processing methods such as spunlace, spunbonding, thermal bonding, meltblown, and needle punching can be used. Among these processing methods, the spunlace method is excellent in softness and drapeability, and the hot bonding method is excellent in bulkiness and flexibility. When a plurality of through holes are formed in the top sheet 11, urine and the like can be absorbed quickly. In the illustrated form, the top sheet 11 is wrapped around the side edge portion of the absorbent body 13 and extends to the back side of the absorbent body 13 .
作為覆蓋吸收體13的背面側(肌膚非抵接面側)之不透液性片12，可使用聚乙烯或聚丙烯等不透液性塑膠片，但是近年來從防止悶濕的點而適合使用具有透濕性的片材。此遮水和透濕性片，例如是在聚乙烯或聚丙烯等烯烴系樹脂中熔融混合碳酸鈣等無機微粒子並成型出片後、沿一個軸或兩個軸方向延伸所得到的多微孔性片。圖示形態中，不透液性片12，與頂片11一起在吸收體13的寬度方向的兩側折返到背面側，但是不限定於這種構造，也能夠採用習知的其他構造。As the liquid-impermeable sheet 12 covering the back side (non-skin contact side) of the absorber 13, a liquid-impermeable plastic sheet such as polyethylene or polypropylene can be used, but in recent years, it is suitable from the viewpoint of preventing stuffiness. Use moisture-permeable sheets. This water-shielding and moisture-permeable sheet is, for example, a microporous product obtained by melting and mixing inorganic fine particles such as calcium carbonate into an olefin resin such as polyethylene or polypropylene, molding the sheet, and extending it along one or both axes. Sex movies. In the illustrated form, the liquid-impermeable sheet 12 is folded back to the back side on both sides in the width direction of the absorbent body 13 together with the top sheet 11. However, the structure is not limited to this and other conventional structures may be adopted.
在內裝體10的兩側部，形成有主要是合身於腿圍之立體皺褶BS。此立體皺褶BS，是藉由折返而成為二層片之皺褶片15，以該皺褶片15來形成固定部、本體部、倒伏部分、及自由部分，該固定部，被固定於內裝體10的背面的側部；該本體部，自此固定部經過內裝體的側方延伸直到內裝體的表面的側部；該倒伏部分，是本體部的前後端部以倒伏狀態被固定於內裝體的表面的側部而形成；該自由部分，是將此倒伏部分之間作成非固定的而形成；在此二層片之間，在自由部分的前端部等配設有細長狀的皺褶彈性構件16。再者藉由這種構造，立體皺褶BS，其藉由皺褶彈性構件16的收縮而比吸收體的側緣部更突出的自由部分，成為在產品狀態下的立起。作為皺褶片15，可適當地使用具有撥水性之不織布。Three-dimensional pleats BS are formed on both sides of the inner body 10 to fit mainly around the legs. This three-dimensional pleat BS is formed by folding the pleated sheet 15 into a two-layer sheet. The pleated sheet 15 forms a fixed part, a main part, a lying part, and a free part. The fixed part is fixed inside. The side portion of the back of the inner body 10; the main body portion extends from the fixed portion through the side of the inner body to the side portion of the surface of the inner body; the lodging portion is the front and rear ends of the main body that are in a lodging state. It is fixed to the side part of the surface of the inner body; the free part is formed by making it non-fixed between the lying parts; between the two layers, a slender piece is arranged at the front end of the free part, etc. -shaped pleated elastic member 16. Furthermore, with this structure, the free portions of the three-dimensional gathers BS that protrude further than the side edge portions of the absorber due to contraction of the gather elastic members 16 become erected in the product state. As the wrinkle sheet 15, a water-repellent nonwoven fabric can be suitably used.
作為皺褶彈性構件16，能夠使用通常使用的苯乙烯系橡膠、烯烴系橡膠、氨酯系橡膠、酯系橡膠、聚氨酯、聚乙烯、聚苯乙烯、苯乙烯丁二烯、矽氧、聚酯等原材料。又，為了不易自外側看見，也可以配設成粗度為925dtex以下、張緊度(tension)為150～350%、間隔為7.0mm以下。另外，作為皺褶彈性構件16，除了圖示形態般的絲狀之外，也能夠使用具有某種程度的寬度之帶狀的構件。As the pleated elastic member 16, commonly used styrene-based rubber, olefin-based rubber, urethane-based rubber, ester-based rubber, polyurethane, polyethylene, polystyrene, styrene-butadiene, silicone, and polyester can be used. and other raw materials. In addition, in order to make it difficult to see from the outside, the thickness may be 925 dtex or less, the tension may be 150 to 350%, and the spacing may be 7.0 mm or less. In addition, as the pleated elastic member 16, in addition to the filament-like shape shown in the figure, a strip-shaped member having a certain width can also be used.
構成前述皺褶片15之原材料纖維也與頂片11同樣，除了設為聚乙烯或聚丙烯等烯烴系、聚酯系、以及聚醯胺系等合成纖維之外，還能夠設為人造絲或銅銨纖維等再生纖維、以及棉等天然纖維，能夠使用藉由紡黏法、熱黏法、熔噴法、針刺法等適當的加工法所得到的不織布，但是特別為了防止悶濕，也可以使用抑制單位面積的質量之透氣性優異的不織布。進一步，為了防止尿等的透過，並且防止皮膚發炎且提高肌膚的感觸性(乾爽感)，所以期望使用一種塗布有矽氧系、石蠟金屬系、烷基氯化鉻系撥水劑等之撥水處理不織布，來作為皺褶片15。The raw material fibers constituting the pleated sheet 15 are also similar to the top sheet 11. In addition to being olefin-based fibers such as polyethylene or polypropylene, polyester-based fibers, and polyamide-based synthetic fibers, they can also be rayon or fiber. Regenerated fibers such as cupro ammonium fiber and natural fibers such as cotton can be used. Nonwoven fabrics obtained by appropriate processing methods such as spun bonding, thermal bonding, melt blowing, and needle punching can be used. However, especially to prevent stuffiness, nonwoven fabrics are also used. A nonwoven fabric with excellent air permeability that reduces mass per unit area can be used. Furthermore, in order to prevent the penetration of urine, etc., prevent skin inflammation, and improve the skin's touch (dry feeling), it is desirable to use a water-repellent agent coated with a silicone-based, paraffin metal-based, alkyl chromium chloride-based water repellent, etc. Water-treated nonwoven fabric is used as the pleated sheet 15.
(外裝體的構造例) 外裝體20，也如圖3～圖5所示，被作成分別由推壓片20A和背片20B所構成的2層構造，該推壓片20A和該背片20B由不織布等所構成，在推壓片20A與背片20B之間、及使該背片20B在腰開口的邊緣往內面側折返而成的折返部分20C之間，配設有彈性構件24～26、28，並在自然長度狀態下藉由彈性構件的收縮力使外裝體20收縮，以將伸縮性賦予到外裝體20。平面形狀，藉由用以在中間的兩側部分別地形成腿開口而形成的凹狀的腿圍線29，使得整體被作成大致的沙漏形狀。(Structure example of exterior body) As shown in FIGS. 3 to 5 , the exterior body 20 has a two-layer structure composed of a pressing sheet 20A and a back sheet 20B, respectively. The pressing sheet 20A and the back sheet 20B are made of nonwoven fabric or the like. Elastic members 24 to 26 and 28 are arranged between the pressing sheet 20A and the back sheet 20B, and between the folded portion 20C formed by folding the back sheet 20B inward at the edge of the waist opening. In the natural length state, the exterior body 20 is contracted by the contraction force of the elastic member, thereby imparting stretchability to the exterior body 20 . The planar shape is made into a rough hourglass shape by the concave leg circumference lines 29 formed to respectively form leg openings on both sides of the center.
在圖示形態的外裝體20，作為彈性構件，在如圖1～圖2所示的展開形狀中，具有被配置在腰開口附近23之腰部彈性構件24、及在前身F和後身B中在縱方向上隔開間隔且沿著寬度方向配置的複數條腰下方部彈性構件25，並且在前身F和後身B的各者中具備與腰下方部彈性構件25的群組不同的複數條彎曲彈性構件26、28；該彎曲彈性構件26、28，彎曲成自一方的側封部21沿著一方的腿開口朝向胯部延伸，橫越胯部且沿著另一方的腿開口延伸直到另一方的側封部21的圖案，彼此沒有交叉而隔開間隔地配置。這些彈性構件24~26、28，被固定為在沿著各自的延伸方向被伸長成規定的伸長率的狀態。另外，在本外裝體20中，也可以不設置沿著腿圍線29自前身F的側封部連續直到後身B的側封部之彈性構件。 The exterior body 20 in the illustrated form has, as elastic members, a waist elastic member 24 arranged near the waist opening 23 in the expanded shape shown in FIGS. 1 and 2 , and a front body F and a back body B. A plurality of lower waist elastic members 25 are spaced apart in the longitudinal direction and arranged along the width direction, and each of the front body F and the back body B is provided with a plurality different from the group of lower waist elastic members 25 . The curved elastic members 26 and 28 are bent to extend from one side sealing portion 21 along one leg opening toward the crotch, cross the crotch, and extend along the other leg opening until The patterns of the other side sealing portion 21 do not intersect with each other but are arranged at intervals. These elastic members 24 to 26 and 28 are fixed in a state of being stretched to a predetermined elongation rate along their respective extending directions. In addition, in the present exterior body 20 , the elastic member extending from the side sealing portion of the front body F to the side sealing portion of the back body B along the leg circumference line 29 does not need to be provided.
腰部彈性構件24，是在前身F與後身B接合而成的側封部21的範圍內，縱方向隔開間隔地被配置在腰開口的邊緣附近之複數條的橡膠絲等細長狀的彈性構件，其以緊固身體的腰周圍的方式賦予伸縮力來將尿布穿著在身體上。此腰部彈性構件24，在圖示例中使用橡膠絲，但是例如也可以使用帶狀的伸縮構件。又，圖示形態的腰部彈性構件24，被夾持在腰部中的背片20B的折返部分20C的不織布之間，但是也可以被夾持在推壓片20A與背片20B之間。 The waist elastic member 24 is an elongated elastic member such as a plurality of rubber threads arranged at intervals in the longitudinal direction near the edge of the waist opening within the range of the side seal portion 21 where the front body F and the back body B are joined. A member that imparts a stretch force to fasten the waist circumference of the body so that the diaper can be worn on the body. This waist elastic member 24 uses rubber yarn in the illustrated example, but for example, a belt-shaped elastic member may also be used. Furthermore, the waist elastic member 24 in the illustrated form is sandwiched between the nonwoven fabrics in the folded portion 20C of the back sheet 20B in the waist region, but it may be sandwiched between the pressing sheet 20A and the back sheet 20B.
腰下方部彈性構件25，是在具有側封部21的前後方向的範圍中，縱方向隔開間隔地配置的橡膠絲等細長狀的彈性構件，其各自地對於前身F和後身B的腰圍部分賦予伸縮力來使尿布密合於身體。另外，腰部彈性構件24與腰下方部彈性構件25的界線也可以不必明確。例如，在前身F和後身B中，縱方向隔開間隔地配置在寬度方向上的彈性構件之中，即便不能夠特定其數目，只要在上部側的幾條作為腰部彈性構件而發揮機能，剩下的彈性構件作為腰下方部彈性構件而發揮機能即可。The lower waist elastic member 25 is an elongated elastic member such as rubber threads arranged at intervals in the longitudinal direction in the front-rear direction range having the side sealing portion 21, and each of them is adapted to the waist circumference of the front body F and the back body B. The stretchable part makes the diaper fit tightly to the body. In addition, the boundary between the waist elastic member 24 and the lower waist elastic member 25 does not need to be clear. For example, in the front body F and the back body B, elastic members are arranged at intervals in the longitudinal direction among the elastic members in the width direction. Even if the number cannot be specified, as long as a few pieces on the upper side function as waist elastic members, The remaining elastic members may function as lower waist elastic members.
在後身B中，與腰下方部彈性構件25個別地設置的背側彎曲彈性構件26，是橡膠絲等細長狀的彈性構件，其沿著規定的曲線配置。背側彎曲彈性構件26，也可以是一條但是較佳為複數條，圖示例中是4條橡膠絲等細長狀的彈性構件，這些背側彎曲彈性構件26彼此沒有交叉而隔開間隔地配置。此背側彎曲彈性構件26，不是將2、3條的程度的彈性構件以緊密的間隔配置成一束，而是以形成規定的伸縮區域的方式隔開3～20mm的程度的間隔，較佳為6～16mm的程度的間隔，配置3條以上，較佳為4條以上。In the back body B, the back side bending elastic member 26 provided separately from the lower waist elastic member 25 is an elongated elastic member such as rubber thread, and is arranged along a predetermined curve. The back-side bending elastic member 26 may be one but is preferably a plurality of elongated elastic members such as four rubber threads in the illustrated example. These back-side bending elastic members 26 are arranged at intervals without crossing each other. . This back-side curved elastic member 26 is not a bundle of about 2 or 3 elastic members arranged at close intervals, but is spaced apart at intervals of about 3 to 20 mm to form a predetermined expansion and contraction area. Preferably, At intervals of approximately 6 to 16 mm, 3 or more, preferably 4 or more, are arranged.
在外裝體20的前身F中，與腰下方部彈性構件25個別地設置的腹側彎曲彈性構件28，是橡膠絲等細長狀的彈性構件，其沿著規定的曲線配置。腹側彎曲彈性構件28，也可以是一條但是較佳為複數條，圖示例中是4條絲狀的彈性構件，這些腹側彎曲彈性構件28彼此沒有交叉而隔開間隔地配置。此腹側彎曲彈性構件28，不是將2、3條的程度的彈性構件以緊密的間隔配置成一束，而是以形成規定的伸縮區域的方式隔開3～20mm的程度的間隔，較佳為6～16mm的程度的間隔，配置3條以上，較佳為4條以上。In the front body F of the outer body 20, the ventral curved elastic member 28 provided separately from the lower waist elastic member 25 is an elongated elastic member such as rubber thread, and is arranged along a predetermined curve. The ventral bending elastic member 28 may be one but is preferably a plurality of filamentous elastic members. In the illustrated example, there are four filamentous elastic members. These ventral bending elastic members 28 are arranged at intervals without intersecting each other. This ventral curved elastic member 28 is not a bundle of about 2 or 3 elastic members arranged at close intervals, but is spaced apart at intervals of about 3 to 20 mm to form a predetermined expansion and contraction area. Preferably, At intervals of approximately 6 to 16 mm, 3 or more, preferably 4 or more, are arranged.
另外，如圖2所示，被配置在前身F和後身B中的腰下方部彈性構件25及彎曲彈性構件26、28，在製造時連續地被固定於外裝體20之後，能夠以規定的切斷圖案細緻地切斷與吸收體13重疊的部分的寬度方向的中間部(圖中的二點鏈線包圍的部分)而作成收縮力沒有作用之非收縮部分，且比此非收縮部分更往側方延伸的部分作成收縮力發揮作用之收縮部分(也就是，腰下方部彈性構件25及彎曲彈性構件26、28的剩下的連續部分)。藉此，能夠防止內裝體(特別是吸收體13)的寬度方向的不必要的收縮。當然，如圖8所示，也能夠將腰下方部彈性構件25及彎曲彈性構件26、28，橫跨內裝體10而連續地配置。In addition, as shown in FIG. 2 , the lower waist elastic members 25 and the bending elastic members 26 and 28 arranged in the front body F and the back body B can be fixed to the exterior body 20 in a predetermined manner during manufacturing. The cutting pattern carefully cuts the middle portion in the width direction of the portion overlapping the absorber 13 (the portion surrounded by the two-dot chain line in the figure) to form a non-shrunk portion in which shrinkage force does not act, and compared with this non-shrunk portion The portion extending further laterally serves as the contracted portion where the contractile force acts (that is, the remaining continuous portions of the lower waist elastic member 25 and the curved elastic members 26 and 28). This can prevent unnecessary shrinkage of the inner body (especially the absorbent body 13) in the width direction. Of course, as shown in FIG. 8 , the lower waist elastic member 25 and the curved elastic members 26 and 28 can also be continuously arranged across the interior body 10 .
上述外裝體20，能夠藉由例如日本特開平4-28363號公報、及日本特開平11-332913號公報記載的技術來製造。又，在內裝體10上切斷彎曲彈性構件26、28以使該彈性構件26、28不連續化，能夠適當地採用日本特開2002-35029號公報、日本特開2002-178428號公報、及日本特開2002-273808號公報記載的切斷方法。The outer casing 20 can be manufactured by the technology described in Japanese Patent Application Laid-Open Nos. 11-332913 and 11-332913, for example. In addition, the curved elastic members 26 and 28 are cut in the inner body 10 to make the elastic members 26 and 28 discontinuous. Japanese Patent Application Laid-Open Nos. 2002-35029, 2002-178428, and and the cutting method described in Japanese Patent Application Laid-Open No. 2002-273808.
與圖示例不同，也可以將彎曲彈性構件26、28僅設置在前身F和後身B的任一方上。又，當將彎曲彈性構件26、28設置在前身F和後身B的兩方上時，也能夠採用被配置在前身F之彎曲彈性構件28的群組的一部分或全部，與被配置在後身B之彎曲彈性構件26的群組的一部分或全部呈交叉的形態(未圖示)，但是適合為如圖示例般的被配置在前身F之彎曲彈性構件28的群組，與被配置在後身B之彎曲彈性構件26的群組彼此呈不交叉，且在前後方向的中央部，特別是在稍為偏向前身F的位置，在縱方向上分離的形態。Unlike the illustrated example, the bending elastic members 26 and 28 may be provided only on either the front body F or the rear body B. Furthermore, when the bending elastic members 26 and 28 are provided on both the front body F and the rear body B, it is also possible to use part or all of the group of the bending elastic members 28 arranged in the front body F and the group arranged in the rear body B. Part or all of the group of the bending elastic members 26 of the body B is in a cross shape (not shown), but it is suitable for the group of the bending elastic members 28 of the front body F to be arranged as shown in the figure. The groups of the curved elastic members 26 in the rear body B do not intersect with each other and are separated in the longitudinal direction at the central portion in the front-rear direction, particularly at a position slightly biased toward the front body F.
彈性構件24～26、28在固定時的伸長率能夠適當地規定：當通常的成人用時，能夠設為腰部彈性構件24是160～320%的程度，腰下方部彈性構件25是160～320%的程度，彎曲彈性構件26、28是230～320%的程度。The elongation of the elastic members 24 to 26 and 28 when fixed can be appropriately determined: for normal adult use, it can be about 160 to 320% for the waist elastic member 24 and 160 to 320 for the lower waist elastic member 25 %, the bending elastic members 26 and 28 are 230 to 320%.
(遮罩片) 也如圖1和圖3所示，為了對於被安裝在外裝體20的內面上之內裝體10的前端部和後端部加以遮罩，且防止自內裝體10的前緣和後緣的漏出，也可以設置遮罩片50、60。若進一步詳細說明圖示形態，則前遮罩片50，自前身F的內面之中的腰側端部的折返部分20C的內面遍及整個寬度方向地延伸直到與內裝體10的前端部重疊的位置；後遮罩片60，自後身B的內面之中的腰側端部的折返部分20C的內面遍及整個寬度方向地延伸直到與內裝體10的後端部重疊的位置。使折返部分20C延伸直到與內裝體10重疊的部分，該折返部分20C是使外裝體20在內面折返而構成，也能夠形成與圖示例的遮罩片50、60同等的部分。(mask film) As also shown in FIGS. 1 and 3 , in order to cover the front and rear ends of the inner body 10 mounted on the inner surface of the outer body 20 and to prevent the front and rear edges of the inner body 10 from being To prevent edge leakage, masking pieces 50 and 60 can also be provided. If the illustrated form is further described in detail, the front cover sheet 50 extends from the inner surface of the folded portion 20C at the waist side end among the inner surfaces of the front body F to the entire width direction until it is in contact with the front end of the interior body 10 Overlapping position; the rear cover sheet 60 extends from the inner surface of the folded portion 20C at the waist side end among the inner surfaces of the rear body B to a position overlapping with the rear end of the interior body 10 throughout the entire width direction. . The folded portion 20C, which is formed by folding the outer body 20 on the inner surface, extends to a portion that overlaps the inner body 10. The folded portion 20C can also be formed as a portion equivalent to the mask sheets 50 and 60 in the illustrated example.
(針對吸收體的構造) 吸收體13也可以是如圖3～圖5所示的單層構造，也可以是複數層構成的構造。 作為吸收體13，能夠使用習知的吸收體，例如以紙漿纖維的積纖體、醋酸纖維素等的長絲(filament)集合體、或不織布作為基本，並對應於需要混合、黏固有高吸收性聚合物等而構成的吸收體。 此吸收體13，為了保持形狀和聚合物等，對應於需要而能夠藉由皺紙等具有透液性和保液性之包裝片14來包裝。 吸收體13的整體形狀，被形成為在胯部具有寬度比前後兩側窄的收攏部分的沙漏形狀，但是也能夠作成長方形狀等適當的形狀。(For the structure of the absorber) The absorber 13 may have a single-layer structure as shown in FIGS. 3 to 5 , or may have a plurality of layers. As the absorbent body 13, a conventional absorbent body can be used, for example, based on fiber accumulation of pulp fibers, filament aggregates such as cellulose acetate, or nonwoven fabric, and can be mixed and adhered according to the needs to achieve high absorption. Absorbent body made of polymers.

The overall shape of the absorbent body 13 is an hourglass shape having a gathered portion in the crotch that is narrower in width than the front and rear sides, but it can also be formed into an appropriate shape such as a rectangular shape.
(針對孔眼的構造) 圖7～圖16是放大地表示短褲型拋棄式穿著用物品之在短褲型拋棄式尿布中的孔眼61、62附近之圖。 以下，一邊參照圖7一邊說明孔眼。孔眼61、62，是位於側封部21的寬度方向的中央側，且沿著側封部延伸的部位。孔眼，是外裝體可沿著孔眼切離的部位。(For the structure of the eyelet) 7 to 16 are enlarged views showing the vicinity of the holes 61 and 62 in the pants-type disposable diaper of the pants-type disposable wearing article. Hereinafter, the eyelet will be described with reference to FIG. 7 . The holes 61 and 62 are located at the center side in the width direction of the side sealing portion 21 and extend along the side sealing portion. The eyelet is the part of the exterior body that can be cut away along the eyelet.
第一形態的孔眼之圖7中的孔眼，具有第一孔眼61和第二孔眼62，該第一孔眼61在縱方向延伸，該第二孔眼62自此第一孔眼的下端或上端，往側封部朝向斜下或朝向斜上延伸。再者，以第一孔眼和第二孔眼之2種孔眼作為1個單元，此孔眼單元在縱方向上，以10mm以下的間隔反復地設置有10個～25個。孔眼單元之間的間隔窄的情況，不易產生橫裂，使縱方向的切離可順利地繼續前進。若孔眼單元之間的間隔超過10mm，則縱方向的切離可能會停止而產生橫裂。The eyelet in Figure 7 of the first form of eyelet has a first eyelet 61 and a second eyelet 62. The first eyelet 61 extends in the longitudinal direction, and the second eyelet 62 extends from the lower end or the upper end of the first eyelet to the side. The sealing portion extends obliquely downward or obliquely upward. Furthermore, two types of eyelets, the first eyelet and the second eyelet, are used as one unit, and 10 to 25 eyelet units are repeatedly provided in the longitudinal direction at intervals of 10 mm or less. When the intervals between the perforated units are narrow, transverse cracks are less likely to occur, allowing the longitudinal cutting to proceed smoothly. If the distance between the eyelet units exceeds 10mm, the longitudinal cutting may stop and transverse cracks may occur.
孔眼的孔，較佳為貫穿外裝體20，且第二孔眼62與第一孔眼61的延長線63的夾角α沒有特別限定，較佳為20∘～70∘，更佳為45∘；側封部21與第二孔眼的端部的寬度方向的距離62W較佳為1mm～15mm；第一孔眼61的長度61L是10mm，較佳為5mm～15mm；第二孔眼62的長度62L是7mm，較佳為3mm～10mm；較佳為第一孔眼比第二孔眼的長度更長(61L＞62L)；孔眼的孔是1mm～4mm。 第一孔眼、第二孔眼的長度、角度、及孔的切割尺寸能夠適當地決定，但是較佳為在本形態的範圍內。The hole of the eyelet preferably penetrates the exterior body 20, and the angle α between the second eyelet 62 and the extension line 63 of the first eyelet 61 is not particularly limited, but is preferably 20∘˜70∘, and more preferably 45∘; side The distance 62W in the width direction between the sealing portion 21 and the end of the second eyelet is preferably 1 mm to 15 mm; the length 61L of the first eyelet 61 is 10 mm, preferably 5 mm to 15 mm; the length 62L of the second eyelet 62 is 7 mm. Preferably, it is 3mm~10mm; preferably, the length of the first eyelet is longer than that of the second eyelet (61L>62L); and the hole of the eyelet is 1mm~4mm. The length and angle of the first eyelet and the second eyelet, and the cutting size of the hole can be appropriately determined, but are preferably within the range of this form.
依據短褲型拋棄式尿布，分別在前身F和後身B中設置一對的孔眼。因此，例如在穿著者穿著短褲型拋棄式尿布的狀態下，也可以一次一個孔眼地依序切離，也可以將一對的孔眼同時地切離，也可以自腹側或自背側開始切離。 又，也可以僅在前身設置孔眼、僅在後身設置孔眼、也可以在前身和後身的任一側都設置孔眼。 孔眼，設為被設置在自側封部21直到寬度方向的中央側的內裝體10之間。According to the shorts-type disposable diaper, a pair of eyelets are provided in the front body F and the back body B respectively. Therefore, for example, when the wearer is wearing a shorts-type disposable diaper, the holes may be cut sequentially one at a time, a pair of eyelets may be cut simultaneously, or the cutting may be started from the ventral side or the dorsal side. . Furthermore, the eyelets may be provided only on the front body, the eyelets may be provided only on the rear body, or the eyelets may be provided on either side of the front body and the rear body. The holes are provided between the inner body 10 from the side sealing portion 21 to the center side in the width direction.
在上述實施形態中可以適用於以下形態。各形態，也可以各自變化並適當地組合。The above-mentioned embodiment can be applied to the following aspects. Each form can also be changed individually and combined appropriately.
圖7是放大地表示第一形態中的短褲型拋棄式尿布的孔眼附近之圖。在放大圖中，省略彈性構件24、25。可以自腰開口往腿開口在縱方向往下切離。下方向第二孔眼62自第一孔眼的下端斜向地往下側延伸。施加於下方向第二孔眼62的下端之切離的力量，朝向下個單元的第一孔眼61，所以可以進行縱方向的連續的切離。 較佳為前述第一孔眼的端部，與往前述側封部側斜向延伸的第二孔眼的起始點連在一起。前述第一孔眼與前述第二孔眼連成一串，藉此切離自前述第一孔眼往前述第二孔眼連續地發生。 較佳為此第一孔眼的端部往第二孔眼的起始點的連續性，設置在全部的實施形態中。 又，側封部21在第二孔眼62的延長線上，所以即便在萬一第二孔眼的端部中的切離沒有回到第一孔眼61的情況下，也可以沿著側封部21使往腿開口的切離繼續前進。側封部21本身的強度足夠，所以在途中不易發生橫裂。FIG. 7 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in the first form. In the enlarged view, the elastic members 24, 25 are omitted. It can be cut longitudinally downward from the waist opening to the leg opening. The downward second eyelet 62 extends diagonally downward from the lower end of the first eyelet. The force exerted to cut off the lower end of the second hole 62 is directed toward the first hole 61 of the next unit, so continuous cutting in the longitudinal direction can be performed. Preferably, the end of the first eyelet is connected to the starting point of the second eyelet that extends obliquely toward the side sealing portion. The aforementioned first eyelet and the aforementioned second eyelet are connected in a series, whereby the cutting occurs continuously from the aforementioned first eyelet to the aforementioned second eyelet. Preferably, continuity from the end of the first eyelet to the starting point of the second eyelet is provided in all embodiments. In addition, the side sealing portion 21 is on the extension line of the second eyelet 62, so even if the end portion of the second eyelet is not cut back to the first eyelet 61, it can be made along the side sealing portion 21. Continue cutting toward the leg opening. The side sealing portion 21 itself has sufficient strength, so it is unlikely to be transversely cracked along the way.
圖8是放大地表示第一形態的變化例中的短褲型拋棄式尿布的孔眼附近之圖。相較於第一孔眼61的長度，第二孔眼62的長度更短。藉此，相較於橫向，切離在縱向上繼續前進的勁勢更強，所以即便是力量不強的利用者也能夠容易地切離尿布。FIG. 8 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in a variation of the first aspect. Compared with the length of the first eyelet 61, the length of the second eyelet 62 is shorter. As a result, the cutting force is stronger in the longitudinal direction than in the horizontal direction, so even a user with weak strength can easily cut off the diaper.
圖9是放大地表示第一形態的變化例中的短褲型拋棄式尿布的孔眼附近之圖。在放大圖中，省略彈性構件24、25。如放大圖所示，第一孔眼61的孔部分，位於自第二孔眼62的終點往寬度方向的中央側的延長線上。即便在產生橫裂的情況，在橫裂的去處配置有第一孔眼，使得在第一孔眼承受橫裂，所以往縱方向的切離可以連續。FIG. 9 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in a variation of the first aspect. In the enlarged view, the elastic members 24, 25 are omitted. As shown in the enlarged view, the hole portion of the first eyelet 61 is located on an extension line from the end point of the second eyelet 62 toward the center side in the width direction. Even if a transverse crack occurs, a first hole is arranged at the place where the transverse crack occurs, so that the first hole can bear the transverse crack, so the cutting in the longitudinal direction can be continuous.
圖10是放大地表示第一形態中的短褲型拋棄式尿布的孔眼附近之圖。第二孔眼62的朝向，被設置成相當於與圖7所示的第一形態相反之上方向第二孔眼，可以自腿開口往腰開口，進行在縱方向進行往上的切離。 與圖7同樣，側封部21在上方向第二孔眼62的延長線上，所以即便在萬一第二孔眼的端部中的切離沒有回到第一孔眼61的情況，也可以沿著側封部21使往腿開口的切離繼續前進。側封部21本身的強度足夠，所以在途中不易發生橫裂。 當交換時，看顧者容易使用能夠自下往上的切離的形態，以切離尿布。又，自下往上拉扯的力量，比自上往下拉下的力量更強，所以力量較弱的利用者能夠容易地切離尿布。FIG. 10 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in the first form. The direction of the second eyelet 62 is set to correspond to the second eyelet in the upper direction opposite to the first form shown in FIG. 7, so that upward cutting can be performed in the longitudinal direction from the leg opening to the waist opening. 7, the side sealing portion 21 is on the extension line of the second eyelet 62 upward, so even if the end of the second eyelet is not cut back to the first eyelet 61, it can be sealed along the side. The sealing portion 21 continues the cutting to the leg opening. The side sealing portion 21 itself has sufficient strength, so it is unlikely to be transversely cracked along the way. When changing, the caregiver can easily use the form of cutting from bottom to top to cut off the diaper. In addition, the force of pulling from bottom to top is stronger than the force of pulling from top to bottom, so users with weak strength can easily cut off the diaper.
圖11是放大地表示第一形態中的短褲型拋棄式尿布的孔眼附近之圖。本形態合併地具有圖7和圖10所示的形態，分別地自第一孔眼的上端和下端，具有上方向第二孔眼62A和下方向第二孔眼62B。因此，切離可以是縱方向往下，也可以是縱方向往上，力量較弱的被看顧者自己進行的切離或由他人來交換尿布時進行的切離，都能夠在兩方向上容易地進行。FIG. 11 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in the first form. This form has the form shown in FIG. 7 and FIG. 10 together, and has the upward second eyelet 62A and the downward second eyelet 62B respectively from the upper end and the lower end of the first eyelet. Therefore, the incision can be made in the longitudinal direction downward or in the longitudinal direction upward. The incision performed by the weak caregiver by himself or by others when changing diapers can be easily performed in both directions. carried out.
圖12是放大地表示第二形態中的短褲型拋棄式尿布的孔眼附近之圖。在本形態中，下方向第二孔眼62，朝向下個單元孔眼的第一孔眼61，往反向下側折返。第二孔眼62的終點朝向下個單元的第一孔眼61的起始點，藉此將切離的朝向往下個孔眼單元誘導，而不易產生在孔眼間的橫裂，相較於自圖7直到圖11的第一形態，使得切離更順利地繼續前進。FIG. 12 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in the second form. In this form, the downward direction is folded back toward the second eyelet 62 and toward the first eyelet 61 of the next unit eyelet in the opposite downward direction. The end point of the second eyelet 62 faces the starting point of the first eyelet 61 of the next unit, thereby inducing the cutting direction toward the next eyelet unit, making it less likely to produce transverse cracks between the holes, compared to Figure 7 Until the first form in Figure 11, the cut-off can continue to move forward more smoothly.
圖13是放大地表示第三形態中的短褲型拋棄式尿布的孔眼附近之圖。在本形態中，圖12的形態的孔眼在縱方向自下往上。上方向第二孔眼62，朝向下個單元孔眼的第一孔眼61，往反向上側折返。將切離的朝向往下個孔眼單元誘導，而不易產生在孔眼間的橫裂，相較於自圖7直到圖11的第一形態，使得切離更順利地連串。 當交換時，看顧者容易使用能夠自下往上的切離的形態，以切離尿布。又，自下往上拉扯的力量，比自上往下拉下的力量更強，所以力量較弱的利用者能夠容易地切離尿布。FIG. 13 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in the third aspect. In this form, the holes in the form of Figure 12 are vertically oriented from bottom to top. The second eyelet 62 is directed upward, toward the first eyelet 61 of the next unit eyelet, and is folded back to the opposite upper side. The cutting direction is directed toward the next perforation unit, so that transverse cracks between the perforations are less likely to occur. Compared with the first form from Figure 7 to Figure 11, the cut-offs can be continued more smoothly. When changing, the caregiver can easily use the form of cutting from bottom to top to cut off the diaper. In addition, the force of pulling from bottom to top is stronger than the force of pulling from top to bottom, so users with weak strength can easily cut off the diaper.
圖14是放大地表示第四形態中的短褲型拋棄式尿布的孔眼附近之圖。本形態，是由圖10和圖12所示的第一形態和第二形態組合而成。在放大圖中省略彈性構件24、25。 如放大圖所示，在下方向第二孔眼62B的往反向下側折返62C的延長線62Q上，具有下個單元的第一孔眼61，在上方向第二孔眼62A的延長線62P上，配置有上個單元的下方向第二孔眼62B。 下方向第二孔眼62B的長度，較佳為以不過度靠近側封部21的方式取適當的長度。上方向第二孔眼的延長線62P，及下方向第二孔眼的折返的延長線62Q的長度沒有特別規定。也包含下方向第二孔眼62B的往反向下側折返62C接觸第一孔眼61、及上方向第二孔眼62A接觸下方向第二孔眼62B的至少一方的形態。 本形態，孔眼間的距離窄，切離的力量不易在孔眼間喪失，所以容易產生在單元的孔眼間的誘導，使得撕裂容易沿著孔眼發生。FIG. 14 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in the fourth aspect. This form is a combination of the first form and the second form shown in Figures 10 and 12. The elastic members 24, 25 are omitted in the enlarged view. As shown in the enlarged view, the first eyelet 61 of the next unit is arranged on the extension line 62Q of the downward second eyelet 62B that is folded back to the opposite lower side 62C, and is arranged on the extension line 62P of the upper second eyelet 62A. There is a second hole 62B directed downward from the previous unit. The length of the second downward hole 62B is preferably an appropriate length so as not to be too close to the side sealing portion 21 . The lengths of the upward extension line 62P of the second eyelet and the downward folded extension line 62Q of the second eyelet are not particularly defined. It also includes the form in which the reverse downward folding 62C of the downward second eyelet 62B contacts the first eyelet 61 and the upward second eyelet 62A contacts at least one of the downward second eyelet 62B. In this form, the distance between the holes is narrow, and the cutting force is not easily lost between the holes, so it is easy to be induced between the holes of the unit, making it easy for tears to occur along the holes.
圖15是放大地表示第五形態中的短褲型拋棄式尿布的孔眼附近之圖。在本形態中，在尿布的寬度方向的中央側的自腰開口直到腿開口，沿著第一孔眼61配置有輔助孔眼64。此輔助孔眼64，用以使彈性構件24、25造成的切離的中斷不易發生。 在彈性構件24、25上沒有第一孔眼61的孔之部分，配置有輔助孔眼64的孔，所以即便縱方向的切離因為彈性構件而停止並往橫方向裂開時因為在橫裂的去處具有輔助孔眼64的孔，所以切離會再次往縱方向繼續前進。既便在彈性構件24、25上沒有輔助孔眼64的孔的情況，也能夠藉由橫裂附近的輔助孔眼64而再次開始往縱方向的切離。 輔助並誘導切離之縱方向輔助孔眼64的配置，可設置在全部的實施例中。Fig. 15 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in the fifth aspect. In this form, auxiliary eyelets 64 are arranged along the first eyelets 61 from the waist opening to the leg opening on the central side in the width direction of the diaper. This auxiliary eyelet 64 is used to make the interruption of cutting caused by the elastic members 24 and 25 less likely to occur. The holes of the auxiliary holes 64 are arranged in the portions of the elastic members 24 and 25 that do not have the holes of the first holes 61. Therefore, even if the cutting in the longitudinal direction is stopped by the elastic members and the rupture occurs in the transverse direction, because the transverse rupture occurs at the place where the lateral rupture occurs. There are holes with auxiliary holes 64, so the cutting will continue to advance in the longitudinal direction again. Even if there is no hole for the auxiliary eyelet 64 in the elastic members 24 and 25, the cutting in the longitudinal direction can be started again by the auxiliary eyelet 64 near the transverse tear. The arrangement of longitudinal auxiliary holes 64 to assist and induce shearing can be provided in all embodiments.
圖16是放大地表示第六形態中的短褲型拋棄式尿布的孔眼附近之圖。在本形態中，在自第二孔眼62的終點之第二孔眼的延長線上具有U字型的孔之輔助孔65，藉此使切離不易朝向往側封部21，而往下個第一孔眼誘導。 輔助並誘導切離之縱方向輔助孔65的配置，可設置在全部的實施例中。FIG. 16 is an enlarged view showing the vicinity of the eyelets of the pants-type disposable diaper in the sixth aspect. In this form, there is an auxiliary hole 65 of a U-shaped hole on the extension line of the second hole from the end point of the second hole 62, thereby making it difficult to cut off toward the side sealing portion 21 and toward the next first hole. Hole induction. The arrangement of longitudinal auxiliary holes 65 to assist and induce cutting can be provided in all embodiments.
