Description
本發明係關於一種丟棄式尿褲，尤其關於一種具有腿箍部之丟棄式尿褲。The present invention relates to a disposable diaper, and more particularly to a disposable diaper having a leg cuff.
先前具有腿箍部之丟棄式尿褲已廣為人知。此種尿褲係沿尿褲之長度方向之兩側部設有一對腿箍部，且亦有於腿箍部之寬度方向外側形成有腿皺褶之褶皺者。Discarded diapers that previously had leg cuffs are well known. Such a diaper is provided with a pair of leg cuff portions on both sides in the longitudinal direction of the diaper, and also has wrinkles for forming leg gathers on the outer side in the width direction of the leg cuff portion.
於此種丟棄式尿褲中存有如下情形：給嬰幼兒穿著尿褲時，尿褲之腿箍部之腿皺褶之褶皺會進入尿褲內側，若任由如此情形，則於穿著尿褲之過程中，會由腿箍部產生滲漏。因此，監護人等給嬰幼兒穿著尿褲時，必須將腿皺褶之褶皺拉出到尿褲之外側而進行整理，增加穿著尿褲時之時間及工夫。In such a disposable diaper, there is a case in which, when wearing a diaper for an infant, the wrinkles of the leg folds of the leg cuff of the diaper enter the inside of the diaper, and if so, the diaper is worn. During the process, leakage will occur from the leg cuffs. Therefore, when the guardian or the like wears the diaper to the infant, the pleats of the leg folds must be pulled out to the outside of the diaper for finishing, and the time and effort for wearing the diaper are increased.
又，於日本特表2002－522117號公報以及日本特表2003－513708號公報中揭示有一種丟棄式尿褲，其係位於尿褲寬度方向最外側之腿彈性構件配置於腿箍部寬度方向外側之端部附近者。如此構成之尿褲，因腿彈性構件配置於腿箍部之寬度方向外側之端部附近，故於腿箍部之外側無褶皺或幾乎未形成褶皺。因此，給嬰幼兒穿著尿褲時，不會有尿褲之腿箍部之腿皺褶之褶皺進入尿褲內側之事，且穿著尿褲時無須整理腿部周圍就可完成穿著，故可快速穿著。又，其於外觀上亦細長，提高了美觀性。Further, a disposable diaper in which the leg elastic members located at the outermost side in the width direction of the diaper are disposed on the outer side in the width direction of the leg cuff portion is disclosed in Japanese Laid-Open Patent Publication No. 2002-522117 and Japanese Patent Publication No. 2003-513708. Near the end. Since the leg elastic member is disposed in the vicinity of the end portion in the width direction outer side of the leg cuff portion, the diaper thus constituted has no wrinkles or almost no wrinkles on the outer side of the leg cuff portion. Therefore, when wearing a diaper for an infant, there is no crease of the leg folds of the leg of the diaper into the inside of the diaper, and the diaper can be worn without having to organize the circumference of the leg, so that it can be quickly Dressed. Moreover, it is also slender in appearance, which improves the appearance.
又，於日本特表2002－522117號公報以及日本特表2003－513708號公報中所揭示之丟棄式尿褲，因於腿皺褶之上表面(皮膚接觸面側)接合有其他片體，腿皺褶並不直接接觸穿著者之皮膚，故可消除因腿皺褶直接接觸皮膚所引起之皮膚觸感不良。Further, the disposable diaper disclosed in Japanese Laid-Open Patent Publication No. 2002-522117 and Japanese Laid-Open Patent Publication No. 2003-513708 has other sheets joined to the upper surface (skin contact surface side) of the leg gathers. The wrinkles do not directly contact the wearer's skin, so the skin feels poor due to direct contact with the skin due to leg wrinkles can be eliminated.
然而，業者期望對於如此構成之丟棄式尿褲，可進一步提高腿箍部之皮膚觸感。However, it is expected that the disposable diaper thus constructed can further improve the skin feel of the leg cuffs.
因此，本發明之目的在於提供一種丟棄式尿褲，其係於具有以被覆片體被覆腿皺褶之上表面而構成之腿箍部的丟棄式尿褲中，可進一步提高腿箍部之皮膚觸感。SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a disposable diaper which is capable of further improving the skin of the leg cuff portion in a disposable diaper having a leg cuff portion which is formed by covering the upper surface of the leg wrinkle with the covered sheet body.

腿箍部5至少於胯下部A中，包括腿皺褶51、及以被覆腿皺褶51上表面之方式藉由上部接合部71接合於該上表面之被覆片體62。The leg cuff portion 5 includes at least the leg gathers 51 and the cover sheet body 62 joined to the upper surface by the upper joint portion 71 so as to cover the upper surface of the leg gathers 51 at least in the crotch portion A.
所謂腿箍部5，係指於製品之長度方向中央部，自製品之寬度方向外側之端部至吸收體4之寬度方向外側之端部4A之間的前後方向之區域。所謂胯下部A，係穿著時配置於穿著者(被穿著者)之胯下部(股間部)之區域，而於本實施形態中，係指背側之側翼部(side flap)91、91(下述)與腹側之側翼部91、91(下述)之間的區域。所謂背側部B以及腹側部C，係指分別相較於胯下部A之背側以及腹側之區域。The leg cuff portion 5 is a region in the front-rear direction between the end portion in the width direction of the product and the end portion 4A on the outer side in the width direction of the absorbent body 4 in the center portion in the longitudinal direction of the product. The lower part A of the crotch is placed in the lower part (the inter-femoral part) of the wearer (the wearer) when worn, and in the present embodiment, the side flaps 91 and 91 of the back side are referred to. The area between the side flap portions 91 and 91 (described below). The back side B and the ventral part C refer to the areas on the back side and the ventral side of the lower part A, respectively.
腿皺褶51係藉由腿皺褶形成片體8自上下夾持並列於寬度方向的複數個腿彈性構件52、52、52而形成。本實施形態中之腿彈性構件52具有線狀形態，並以與腿箍部5之寬度方向外側之端部(自由端)5A呈大致平行之方式配置有3條。並列於寬度方向之複數個腿彈性構件52、52、52中，配置於寬度方向最外側之腿彈性構件52A，係配置於一對腿箍部5各自之寬度方向外側之端部5A或其附近。因此，於配置於寬度方向之最外側之腿彈性構件52A之外側，無或幾乎未形成腿皺褶51之褶皺。The leg gathers 51 are formed by the leg gathers forming sheet 8 being sandwiched by a plurality of leg elastic members 52, 52, 52 which are arranged in the width direction from above and below. In the present embodiment, the leg elastic members 52 have a linear shape, and are arranged in a substantially parallel manner with the end portions (free ends) 5A of the leg cuff portions 5 in the width direction. In the plurality of leg elastic members 52, 52, and 52 which are arranged in the width direction, the leg elastic members 52A disposed on the outermost side in the width direction are disposed at or near the end portion 5A of the outer side in the width direction of each of the pair of leg cuff portions 5 . Therefore, the wrinkles of the leg gathers 51 are not formed or hardly formed on the outer side of the leg elastic members 52A disposed on the outermost side in the width direction.
所謂「配置於腿箍部之寬度方向外側之端部」，係指配置於自腿箍部5之寬度方向外側之端部5A至2 mm之內的區域。所謂「配置於腿箍部之寬度方向外側之端部附近」，係指配置於自腿箍部5之寬度方向外側之端部5A起超過2 mm至5 mm內的區域。於本實施形態中，配置於寬度方向最外側之腿彈性構件52A，係配置於腿箍部5之寬度方向外側之端部5A。The term "arranged on the outer side in the width direction of the leg cuff portion" means an area disposed within the outer end portion 5A to 2 mm from the leg cuff portion 5 in the width direction. The term "disposed in the vicinity of the end portion in the width direction of the leg cuff portion" means an area which is disposed within the outer end portion 5A of the leg cuff portion 5 in the width direction and which is more than 2 mm to 5 mm. In the present embodiment, the leg elastic members 52A disposed on the outermost side in the width direction are disposed at the end portions 5A on the outer side in the width direction of the leg cuff portions 5.
腿皺褶形成片體係由自上述外層片體8，詳細而言，自外層片體8中之吸收體4之寬度方向外側之端部4A向寬度方向外側延伸出之區域所形成。The leg gathers forming sheet system is formed from the outer layer sheet 8 and, in detail, from the outer peripheral end portion 4A of the outer layer body 8 in the width direction outer side extending outward in the width direction.
腿皺褶形成片體8係自寬度方向外側之上表面側折返至寬度方向內側而形成2層區域82，於2層區域82中夾持有腿彈性構件52。2層區域82之寬度為例如15~50 mm。再者，將腿皺褶形成片體8中之1層區域稱為「1層區域81」。The leg gather forming sheet 8 is folded back to the inner side in the width direction from the outer surface on the outer side in the width direction to form a two-layered region 82, and the leg elastic member 52 is sandwiched in the two-layered region 82. The width of the two-layered region 82 is, for example, 15~50 mm. Further, the one-layer region in the leg gathers forming sheet 8 is referred to as "1 layer region 81".
於腿皺褶51中，背面片體3介於腿皺褶形成片體8中之2層區域82之下層82A、與腿彈性構件52之間。背面片體3之寬度方向外側之端部3A位於配置於寬度方向最外側之腿彈性構件52A之寬度方向的外側，較好的是位於寬度方向外側1~5 mm處。如此，可藉由使背面片體3介於腿皺褶51之間而提高腿箍部5之防漏性。In the leg gathers 51, the back sheet 3 is interposed between the lower layer 82A of the two-layered region 82 in the leg gather forming sheet 8 and the leg elastic member 52. The end portion 3A on the outer side in the width direction of the back sheet 3 is located on the outer side in the width direction of the leg elastic member 52A disposed on the outermost side in the width direction, and is preferably located 1 to 5 mm on the outer side in the width direction. Thus, the leakage preventing property of the leg cuff portion 5 can be improved by interposing the back sheet body 3 between the leg gathers 51.
於腿皺褶形成片體8之2層區域82的內部，腿皺褶形成片體8與背面片體3並未實質性接合，但腿彈性構件52、腿皺褶形成片體8以及背面片體3可以黏接劑等周知之接合方法相接合。In the inside of the two-layered region 82 of the leg gathers forming sheet 8, the leg gathers forming sheet 8 and the back sheet 3 are not substantially joined, but the leg elastic members 52, the leg gathers form the sheet 8 and the back sheet The body 3 can be joined by a known bonding method such as an adhesive.
於腿皺褶51之上表面，以被覆該上表面之方式接合有被覆片體62。腿皺褶51與被覆片體62係藉由上部接合部71而接合。The covering sheet 62 is joined to the upper surface of the leg gather 51 so as to cover the upper surface. The leg gathers 51 and the covering sheets 62 are joined by the upper joint portion 71.
上部接合部71之寬度方向外側之端部71A位於配置於寬度方向最外側之腿彈性構件52A之寬度方向的內側。上部接合部71之寬度方向外側之端部71A與配置於寬度方向最外側之腿彈性構件52A之寬度方向的間隔W1[參照圖3(b)]，較好的是1~20 mm，進而較好的是1~10 mm。The end portion 71A on the outer side in the width direction of the upper joint portion 71 is located on the inner side in the width direction of the leg elastic member 52A disposed on the outermost side in the width direction. The distance W1 between the end portions 71A on the outer side in the width direction of the upper joint portion 71 and the leg elastic members 52A disposed on the outermost side in the width direction (see FIG. 3(b)) is preferably 1 to 20 mm, and further Good is 1~10 mm.
於藉由上部接合部71而接合之腿皺褶51以及被覆片體62中，腿皺褶51之寬度方向外側之端部51A，與被覆片體62之寬度方向外側之端部62A大約一致。所謂「大約一致」，係指腿皺褶51之寬度方向外側之端部51A，與被覆片體62之寬度方向外側之端部62A之寬度方向之位置偏差為10 mm以內。In the leg gathers 51 and the cover sheet body 62 joined by the upper joint portion 71, the end portion 51A on the outer side in the width direction of the leg gathers 51 substantially coincides with the end portion 62A on the outer side in the width direction of the cover sheet 62. The term "approximately" means that the end portion 51A of the outer side in the width direction of the leg gather 51 is displaced within 10 mm from the width direction of the outer end portion 62A of the covering sheet 62 in the width direction.
上部接合部71既可於面方向上連續形成，亦可於面方向上非連續形成，但，考慮到塗布步驟之簡便性及乾燥後腿皺褶51之柔軟性方面，較好的是於面方向上非連續地形成。至於面方向上之非連續的塗布形狀，例如可列舉：螺旋(spiral)形狀、條紋(stripe)形狀、波紋(wave)形狀、點(dot)狀。面方向上連續的塗布形狀(所謂全面塗抹)，可藉由如塗布機(coater)方式之接觸式塗布而形成，又，亦可藉由實質上無間隙地進行如狹縫(slot)方式之噴霧式塗布而形成。再者，若藉由噴霧式塗布，根據噴霧條件的不同，可於面方向上形成非連續的塗布形狀(點狀)，又，亦可於面方向上形成連續的塗布形狀(全面塗抹)。The upper joint portion 71 may be formed continuously in the surface direction or may be discontinuously formed in the surface direction. However, in view of the simplicity of the coating step and the softness of the leg gathers 51 after drying, it is preferred to face. The direction is discontinuously formed. As for the discontinuous coating shape in the plane direction, for example, a spiral shape, a stripe shape, a wave shape, and a dot shape may be mentioned. The continuous coating shape in the surface direction (so-called full application) can be formed by contact coating such as a coater method, or by a substantially slot-free method. It is formed by spray coating. Further, by spray coating, a discontinuous coating shape (dot shape) can be formed in the surface direction depending on the spray conditions, and a continuous coating shape (full application) can be formed in the surface direction.
於正面片體2之上表面，沿吸收體4之長度方向兩側部4A設置有一對立體皺褶6、6。被覆片體62係由自該立體皺褶形成用片體，詳細而言，自立體皺褶形成用片體中之吸收體4之寬度方向外側之端部4A向寬度方向外側延伸出的區域所形成。On the upper surface of the front sheet 2, a pair of three-dimensional wrinkles 6, 6 are provided along both longitudinal direction portions 4A of the absorbent body 4. The cover sheet 62 is formed from the sheet for forming a three-dimensional gather, and in detail, an area extending outward in the width direction from the outer end portion 4A of the absorbent body 4 in the sheet for forming a three-dimensional gather is formed. form.
於本實施形態中，立體皺褶6藉由如下方式而形成：將2條線狀之立體皺褶形成用之彈性構件61與立體皺褶6之自由端大致平行配置，該彈性構件61夾持於被覆片體62中之寬度方向內側之端部或其附近。In the present embodiment, the three-dimensional gathers 6 are formed by arranging the two elastic members 61 for forming the three-dimensional gathers in a line substantially parallel to the free ends of the three-dimensional gathers 6, and the elastic members 61 are sandwiched. The end portion of the covering sheet 62 in the width direction inner side or its vicinity.
再者，各立體皺褶6係於拉伸狀態平放於正面片體2上，但，於圖3(a)中，為方便起見，顯示以相對於正面片體2豎起之狀態。Further, each of the three-dimensional wrinkles 6 is placed on the front sheet 2 in a stretched state. However, in FIG. 3(a), for the sake of convenience, the state is erected with respect to the front sheet 2.
被覆片體62係藉由基端接合部73，跨越長度方向而以直線狀接合於正面片體2之寬度方向外側之端部2A之上表面。因此，腿皺褶51係經由立體皺褶6而接合於正面片體2。The coated sheet body 62 is linearly joined to the upper surface of the end portion 2A on the outer side in the width direction of the front sheet body 2 in the longitudinal direction by the base end joint portion 73. Therefore, the leg gathers 51 are joined to the front sheet body 2 via the three-dimensional gathers 6.
立體皺褶6，其於背側部B以及腹側部C中，位於基端接合部73之尿褲寬度方向內側的區域係接合於正面片體2上。The three-dimensional gathers 6 are joined to the front sheet body 2 in the back side portion B and the front side portion C in a region on the inner side in the diaper width direction of the base end joint portion 73.
再者，使用圖3(a)以及圖3(b)，就丟棄式尿褲1之右側構成加以說明，但，丟棄式尿褲1之左側亦為同樣構成。Further, the configuration of the right side of the disposable diaper 1 will be described with reference to Figs. 3(a) and 3(b), but the left side of the disposable diaper 1 has the same configuration.
如圖1以及圖2中所示，一對立體皺褶6、6，分別於背側部B中接合其長度方向一端部，於腹側部C中接合其長度方向另一端部。As shown in FIGS. 1 and 2, the pair of three-dimensional gathers 6, 6 are joined to the one end portion in the longitudinal direction of the back side portion B, and the other end portion in the longitudinal direction is joined to the front side portion C.
又，背側部B以及腹側部C中之腰部D，分別設置有片狀之腰彈性構件(未圖示)，且藉由該腰彈性構件而形成有腰皺褶(waist gather)。Further, a waist elastic member (not shown) is provided in each of the back side portion B and the waist portion D in the front side portion C, and a waist gather is formed by the waist elastic member.
於背側部B之寬度方向外側之兩端部，分別形成有向寬度方向外側延伸出之側翼部91、91。於各側翼部91中，向寬度方向外側延伸設置有黏扣帶(fastening tape)92。於黏扣帶92中，設置有機械扣件(mechanical fastener)之鉤構件93。至於鉤構件93，可使用於該技術領域中眾所周知者，並無特別限制。Side portions 91 and 91 extending outward in the width direction are formed at both end portions of the back side portion B on the outer side in the width direction. In each of the side flap portions 91, a fastening tape 92 is extended outward in the width direction. In the fastening tape 92, a hook member 93 of a mechanical fastener is provided. As for the hook member 93, it can be used for those well known in the art, and is not particularly limited.
於腹側部C之兩側部，亦形成有各自向寬度方向外側延伸出之側翼部91、91。於腹側部C中之背面片體3之外表面(非皮膚接觸面側)，設置有可自由黏止黏扣帶92之鉤構件93的著落帶(Landing tape)(未圖示)。Side portions 91 and 91 each extending outward in the width direction are formed on both side portions of the front side portion C. A landing tape (not shown) that can freely adhere the hook member 93 of the fastening tape 92 is provided on the outer surface (non-skin contact surface side) of the back sheet 3 in the front side portion C.
丟棄式尿褲1於自然狀態下，藉由一對腿箍部5、5中之腿皺褶51、51以及一對立體皺褶6、6之收縮力，如圖1所示，向皮膚接觸面側彎曲。所謂「自然狀態」，係指無重力以外的外力實質上作用於丟棄式尿褲之狀態。In the natural state, the disposable diaper 1 is brought into contact with the skin by the contraction force of the leg gathers 51, 51 and the pair of three-dimensional gathers 6, 6 in the pair of leg cuffs 5, 5, as shown in FIG. The side is curved. The "natural state" refers to a state in which an external force other than gravity acts substantially on a disposable diaper.
又，丟棄式尿褲1於拉伸狀態下，從巨觀來看，具有長度方向中央部內縮之砂漏狀形狀。所謂「拉伸狀態」，係指解除藉由伸長固定於尿褲的各彈性構件的收縮而收縮之尿褲的收縮的狀態，換而言之，係指各皺褶(彈性構件)於尿褲之長度方向以及寬度方向同時伸長為尿褲之最大尺寸的狀態。Further, in the stretched state, the disposable diaper 1 has an hourglass shape in which the central portion in the longitudinal direction is contracted from the macroscopic view. The "stretched state" refers to a state in which the contraction of the diaper which is contracted by the expansion of the elastic members fixed to the diaper is released, in other words, the pleats (elastic members) in the diaper The length direction and the width direction simultaneously elongate to the state of the largest size of the diaper.
較好的是，於尿褲拉伸狀態下，腿箍部5之寬度於長度方向之任一位置均相同，具體而言，較好的是10~70 mm，尤其好的是20~50 mm。於尿褲之拉伸狀態下，胯下部A之長度較好的是50~350 mm，進而較好的是100~250 mm。Preferably, in the stretched state of the diaper, the width of the leg cuff portion 5 is the same at any position in the longitudinal direction, and specifically, it is preferably 10 to 70 mm, particularly preferably 20 to 50 mm. . In the stretched state of the diaper, the length of the lower part A is preferably from 50 to 350 mm, and more preferably from 100 to 250 mm.
根據如此而構成之第1實施形態之丟棄式尿褲1，因於腿箍部5之皮膚接觸面側配置有被覆片體62，故腿皺褶51難以直接接觸穿著者之皮膚。又，於腿箍部5之腿皺褶51與被覆片體62之間，因於寬度方向外側之端部5A以及其附近無存在上部接合部71，可形成空氣層，故腿箍部5之寬度方向外側之端部5A附近較柔軟。According to the disposable diaper 1 of the first embodiment configured as described above, since the covering sheet 62 is disposed on the skin contacting surface side of the leg cuff portion 5, it is difficult for the leg gathers 51 to directly contact the wearer's skin. Further, between the leg gathers 51 of the leg cuff portions 5 and the covering sheet body 62, since the upper end portion 5A in the width direction and the vicinity of the vicinity thereof are not present, an air layer can be formed, so that the leg cuff portion 5 The vicinity of the end portion 5A on the outer side in the width direction is soft.
進而，於腿皺褶51中，因配置於寬度方向最外側之腿彈性構件52A，受到上部接合部71之剛性的影響較少，故與藉由上部接合部71而抑制其追從性的寬度方向內側之腿彈性構件52相比，伸縮反應性優良，追從性較好。藉由該等之協同效果，腿箍部5輕柔接觸穿著者之皮膚，皮膚觸感良好，且緊貼皮膚而防漏性亦較高。Further, in the leg gathers 51, since the leg elastic members 52A disposed on the outermost side in the width direction are less affected by the rigidity of the upper joint portion 71, the width of the leg joints 71 is suppressed by the upper joint portion 71. The leg elastic member 52 on the inner side has superior stretchability and good followability. With these synergistic effects, the leg cuffs 5 gently touch the skin of the wearer, the skin feels good, and the skin is tightly attached to the skin and the leakage resistance is also high.
又，因腿彈性構件52係夾持於腿皺褶形成片體8中之折返的2層區域82中，故腿彈性構件52不會自腿皺褶51之寬度方向外側之端部51A脫落。又，因於腿皺褶51之寬度方向外側之端部51A中無須設置接合部，故腿皺褶51之寬度方向外側之端部51A柔軟且有彈性。Further, since the leg elastic members 52 are sandwiched between the folded two-layer regions 82 in the leg gathers forming sheet 8, the leg elastic members 52 do not fall off from the outer end portions 51A of the leg gathers 51 in the width direction. Further, since the joint portion is not required to be provided in the outer end portion 51A of the leg gathers 51 in the width direction, the outer end portion 51A of the leg gather 51 in the width direction is soft and elastic.
其次，就本發明之丟棄式尿褲之其他實施形態，一面參照圖式一面加以說明。關於其他實施形態，重點說明與第1實施形態之不同點。關於未特別說明之方面，可適宜適用第1實施形態之說明。相同構件附有相同符號。Next, another embodiment of the disposable diaper according to the present invention will be described with reference to the drawings. Other embodiments will be described with a focus on differences from the first embodiment. The description of the first embodiment can be suitably applied to the aspects which are not particularly described. The same components are attached with the same symbols.
第2實施形態之丟棄式尿褲1中，如圖4所示，與第1實施形態相比，配置於寬度方向之最外側之腿彈性構件52A未配置於腿箍部5之寬度方向外側之端部5A(腿皺褶51之寬度方向外側之端部51A)處，而係配置於其附近(自端部5A起超過2 mm處至5 mm處以內之區域)。其他之構成則與第1實施形態之丟棄式尿褲1相同。In the disposable diaper 1 of the second embodiment, as shown in FIG. 4, the leg elastic members 52A disposed on the outermost side in the width direction are not disposed outside the width direction of the leg cuffs 5 as compared with the first embodiment. The end portion 5A (the end portion 51A on the outer side in the width direction of the leg gather 51) is disposed in the vicinity thereof (the region from the end portion 5A beyond 2 mm to within 5 mm). The other configuration is the same as that of the disposable diaper 1 of the first embodiment.
根據如此而構成之第2實施形態之丟棄式尿褲1，可發揮與第1實施形態之丟棄式尿褲1同樣之效果。進而，因於腿皺褶51中，其寬度方向外側之端部51A與配置於寬度方向最外側之腿彈性構件52A之間形成有空氣層，故腿皺褶51之寬度方向外側之端部51A未形成一體，於端部51A上排泄物難以一下滲出，從而防漏性較高。According to the disposable diaper 1 of the second embodiment configured as described above, the same effects as those of the disposable diaper 1 of the first embodiment can be obtained. Further, in the leg gathers 51, an air layer is formed between the outer end portion 51A in the width direction and the leg elastic member 52A disposed on the outermost side in the width direction. Therefore, the end portion 51A on the outer side in the width direction of the leg gather 51 is formed. The integral is not formed, and it is difficult for the excretion to ooze out at the end portion 51A, so that the leakage prevention property is high.
又，最容易接觸穿著者之皮膚之部分即寬度方向外側之端部5A難以變硬，端部5A與皮膚輕柔接觸，可消除端部5A之硬度所造成之疼痛等不愉快感及不適感。Further, the end portion 5A which is the outermost portion which is most likely to contact the skin of the wearer, that is, the outer side in the width direction, is hard to be hardened, and the end portion 5A is in gentle contact with the skin, and the unpleasant feeling and discomfort such as pain caused by the hardness of the end portion 5A can be eliminated.
進而，藉由腿皺褶51之寬度方向內側之區域的收縮，腿皺褶51之寬度方向外側之區域成為較大之碎褶(Shirring)，可良好地包裹穿著者之皮膚。Further, by the contraction of the region on the inner side in the width direction of the leg gathers 51, the region on the outer side in the width direction of the leg gathers 51 becomes a large shirring, and the wearer's skin can be satisfactorily wrapped.
於第3實施形態之丟棄式尿褲1中，如圖5(a)及圖5(b)所示，背面片體3之下表面、與外層片體8之上表面中之與背面片體3之下表面所相對之區域(除外層片體8中之2層區域82之上層82B以外之區域)，大致跨越全部區域地藉由下部接合部72而接合。又，於胯下部A中，下部接合部72之寬度方向外側之端部72A，相較腿皺褶51之寬度方向外側之端部51A，位於1~20 mm，較好的是1~10 mm之寬度方向內側。所謂「大致跨越全部區域」，意指從巨觀來看跨越全部區域，例如，即使為如螺旋狀及條紋狀塗布之非連續性塗布，若跨越塗布區域整體而塗布有黏接劑，則符合「大致跨越全部區域」。其他之構成與第1實施形態之丟棄式尿褲1相同。In the disposable diaper 1 of the third embodiment, as shown in Figs. 5(a) and 5(b), the lower surface of the back sheet 3 and the upper surface of the outer sheet 8 are opposite to the back sheet. The region where the lower surface is opposed to each other (excluding the region other than the layer 82B above the two-layer region 82 in the layer body 8) is joined by the lower joint portion 72 substantially across the entire region. Further, in the lower portion A of the crotch, the end portion 72A on the outer side in the width direction of the lower joint portion 72 is located at 1 to 20 mm, preferably 1 to 10 mm, from the end portion 51A on the outer side in the width direction of the leg gather 51. The inside of the width direction. The term "substantially spans the entire area" means that the entire area is spanned from a giant point of view. For example, even if it is a discontinuous coating such as a spiral or a stripe coating, if the adhesive is applied across the entire coating area, it conforms. "About the entire area." The other configuration is the same as that of the disposable diaper 1 of the first embodiment.
根據如此構成之第3實施形態之丟棄式尿褲1，可發揮與第1實施形態之丟棄式尿褲1同樣之效果。進而，藉由下部接合部72將背面片體3與外層片體(腿皺褶形成之片體)8一體化，藉由下部接合部72之剛性，丟棄式尿褲之非皮膚接觸面側易於變硬。但，因至少於腿皺褶51中，其寬度方向外側之端部51A與下部接合部72之寬度方向外側之端部72A之間形成有空氣層，故可對腿皺褶51之寬度方向外側之端部51A確保良好的皮膚觸感。According to the disposable diaper 1 of the third embodiment configured as described above, the same effects as those of the disposable diaper 1 of the first embodiment can be obtained. Further, the back sheet body 3 and the outer layer sheet (sheet formed by the leg gathers) 8 are integrated by the lower joint portion 72, and the non-skin contact surface side of the disposable diaper is easy by the rigidity of the lower joint portion 72. Harden. However, at least the leg gathers 51 have an air layer formed between the outer end portion 51A of the width direction and the outer end portion 72A of the lower joint portion 72 in the width direction, so that the width of the leg gather 51 can be outward. The end portion 51A ensures a good skin feel.
又，配置於寬度方向最外側之腿彈性構件52A，因受到下部接合部72之剛性之影響較少，故與其他腿彈性構件52相比，伸縮反應性優良，追從性較好。Further, since the leg elastic members 52A disposed on the outermost side in the width direction are less affected by the rigidity of the lower joint portion 72, the stretch reactivity is superior to that of the other leg elastic members 52, and the followability is good.
第4實施形態之丟棄式尿褲1，如圖6所示，背面片體3之寬度方向外側之端部3A係由腿皺褶51之寬度方向外側之端部51A遠離，而與下部接合部72之寬度方向外側之端部72A大約一致。其他構成與如圖5(a)所示之第3實施形態之丟棄式尿褲1相同。As shown in FIG. 6, the disposable diaper 1 of the fourth embodiment has the end portion 3A on the outer side in the width direction of the back sheet 3 away from the outer end portion 51A of the leg gather 51 in the width direction, and the lower joint portion. The end portions 72A on the outer side in the width direction of 72 are approximately coincident. The other configuration is the same as that of the disposable diaper 1 of the third embodiment shown in Fig. 5(a).
根據如此而構成之第4實施形態之丟棄式尿褲1，可發揮與第3實施形態之丟棄式尿褲1同樣之效果。進而，於將腿皺褶形成片體8之特定區域(形成2層區域82之上層82B之區域)折返到上表面側，而形成腿皺褶51時，不會將背面片體3之寬度方向外側之端部3A一起捲起，因此，腿皺褶51之寬度方向外側之端部51A不會變硬。According to the disposable diaper 1 of the fourth embodiment configured as described above, the same effects as those of the disposable diaper 1 of the third embodiment can be obtained. Further, when a certain region of the leg gathers forming sheet 8 (a region where the layer 82B is formed on the upper layer 82 side) is folded back to the upper surface side, when the leg gathers 51 are formed, the width direction of the back sheet 3 is not caused. Since the outer end portions 3A are rolled up together, the end portion 51A on the outer side in the width direction of the leg gathers 51 does not become hard.
第5實施形態之丟棄式尿褲1，如圖7所示，與圖4所示之第2實施形態同樣，配置於寬度方向之最外側之腿彈性構件52A，係配設於腿箍部5之寬度方向外側之端部5(腿皺褶51之寬度方向外側之端部51A)之附近(自端部5A起超過2 mm處至5 mm處以內之區域)。其他構成與如圖5(a)所示之第3實施形態之丟棄式尿褲1相同。As shown in FIG. 7, the disposable diaper 1 of the fifth embodiment is disposed on the leg cuff portion 5 in the outermost leg elastic member 52A in the width direction as in the second embodiment shown in FIG. The vicinity of the end portion 5 on the outer side in the width direction (the end portion 51A on the outer side in the width direction of the leg gather 51) (the region from the end portion 5A beyond 2 mm to within 5 mm). The other configuration is the same as that of the disposable diaper 1 of the third embodiment shown in Fig. 5(a).
根據如此而構成之第5實施形態之丟棄式尿褲1，可發揮於第3實施形態之丟棄式尿褲1同樣之效果。進而，與第2實施形態同樣，因於腿皺褶51中，於其寬度方向外側之端部51A與配置於寬度方向最外側之腿彈性構件52A之間形成有空氣層，故可發揮與第2實施形態同樣之效果。According to the disposable diaper 1 of the fifth embodiment configured as described above, the same effect as that of the disposable diaper 1 of the third embodiment can be exhibited. Further, in the leg gathers 51, an air layer is formed between the end portion 51A on the outer side in the width direction and the leg elastic member 52A on the outermost side in the width direction. 2 The same effect as the embodiment.
第6實施形態之丟棄式尿褲1，如圖8所示，與如圖6所示之第4實施形態同樣，其背面片體3之寬度方向外側之端部3A係由腿皺褶51之寬度方向外側之端部51A遠離。其他構成與圖7中所示之第5實施形態之丟棄式尿褲1相同。As shown in Fig. 8, the disposable diaper 1 of the sixth embodiment is similar to the fourth embodiment shown in Fig. 6, and the outer end portion 3A of the back sheet 3 in the width direction is formed by the leg gathers 51. The end portion 51A on the outer side in the width direction is away. The other configuration is the same as that of the disposable diaper 1 of the fifth embodiment shown in Fig. 7 .
根據如此而構成之第6實施形態之丟棄式尿褲1，可發揮與第5實施形態之丟棄式尿褲1同樣之效果。進而，與第4實施形態同樣，因背面片體3之寬度方向外側之端部3A係由腿皺褶51之寬度方向外側之端部51A遠離，故不會將背面片體3之寬度方向外側之端部3A一起捲起，因此，可發揮與第4實施形態同樣之效果。According to the disposable diaper 1 of the sixth embodiment configured as described above, the same effects as those of the disposable diaper 1 of the fifth embodiment can be obtained. Further, in the same manner as the fourth embodiment, the end portion 3A on the outer side in the width direction of the back sheet 3 is separated from the outer end portion 51A of the leg gather 51 in the width direction, so that the outer side of the back sheet 3 is not widened. Since the end portions 3A are rolled up together, the same effects as those of the fourth embodiment can be obtained.
第7實施形態之丟棄式尿褲1，如圖10(a)所示，與第1實施形態相比，上部接合部71包括帶形狀之內側接合部71B、及珠粒(bead)形狀(於長度方向之連續性線狀)之外側接合部71C。外側接合部71C係於內側接合部71B之寬度方向外側留有特定間隔而相隔。內側接合部71B之寬度較好的是10~30 mm。外側接合部71C之寬度較好的是0.5~3 mm。即，第7實施形態中之上部接合部71，其就於內側接合部71B與外側接合部71C之間存在帶狀之非接合區域之方面，全體於面方向上具有非連續性的塗布形狀。再者，於圖10(a)及圖10(b)中，係模式地圖示被覆片體62、上部接合部71以及腿皺褶51分別於厚度方向上相隔之狀態。As shown in FIG. 10(a), the disposable diaper 1 of the seventh embodiment includes a belt-shaped inner joint portion 71B and a bead shape as compared with the first embodiment. The continuity direction in the longitudinal direction is the outer side joint portion 71C. The outer joint portion 71C is spaced apart from the outer side in the width direction of the inner joint portion 71B by a predetermined interval. The width of the inner joint portion 71B is preferably 10 to 30 mm. The width of the outer joint portion 71C is preferably 0.5 to 3 mm. In other words, in the seventh embodiment, the upper joint portion 71 has a strip-shaped non-joining region between the inner joint portion 71B and the outer joint portion 71C, and has a discontinuous coating shape in the entire surface direction. In addition, in FIGS. 10(a) and 10(b), the covered sheet body 62, the upper joint portion 71, and the leg gathers 51 are respectively separated from each other in the thickness direction.
內側接合部71B於僅著眼於其之情形時，既可具有於面方向上連續的塗布形狀，亦可具有於面方向上非連續的塗布形狀。內側接合部71B之塗布形狀可適宜採用上述上部接合部71之塗布形狀(例如全面塗抹、點形狀、螺旋形狀)。The inner joint portion 71B may have a coating shape that is continuous in the plane direction or a coating shape that is discontinuous in the plane direction, when only the case is focused on. The coating shape of the inner joint portion 71B can be suitably selected from the coating shape of the upper joint portion 71 (for example, a full-coating, a dot shape, or a spiral shape).
又，於背側部B之寬度方向外側，如圖10(b)所示，側翼部91之形成原材料中之寬度方向內側區域係以如下方式配置：自寬度方向外側向寬度方向內側，以S形插入到被覆片體62與外側接合部71C之間，及內側接合部71B與腿皺褶51之間。Further, in the outer side in the width direction of the back side portion B, as shown in FIG. 10(b), the inner side in the width direction of the material forming the side flap portion 91 is disposed as follows from the outer side in the width direction to the inner side in the width direction. The shape is inserted between the covering sheet body 62 and the outer joint portion 71C, and between the inner joint portion 71B and the leg gather 51.
其他構成與第1實施形態之丟棄式尿褲1相同。The other configuration is the same as that of the disposable diaper 1 of the first embodiment.
根據如此而構成之第7實施形態之丟棄式尿褲1，可發揮與第1實施形態之丟棄式尿褲1同樣之效果。又，因上部接合部71係包括帶狀之內側接合部71B與珠粒形狀之外側接合部71C，故可藉由寬度方向內側之內側接合部71B而以較強接合力進行接合，同時，可藉由寬度方向外側之外側接合部71C而以較少黏接劑輕柔地接合。According to the disposable diaper 1 of the seventh embodiment configured as described above, the same effects as those of the disposable diaper 1 of the first embodiment can be obtained. Further, since the upper joint portion 71 includes the strip-shaped inner joint portion 71B and the bead-shaped outer joint portion 71C, the inner joint portion 71B on the inner side in the width direction can be joined by a strong joining force, and at the same time, The outer side outer joint portion 71C in the width direction is gently joined with less adhesive.
本發明之丟棄式尿褲，並非限定於上述各實施形態，只要不脫離本發明之宗旨，可進行適宜變更。The disposable diaper of the present invention is not limited to the above embodiments, and can be appropriately modified without departing from the gist of the present invention.
例如，可適宜組合上述各實施形態中之構成。For example, the configuration in each of the above embodiments can be combined as appropriate.
腿皺褶只要藉由腿皺褶形成片體上下挾持並列於寬度方向之複數個腿彈性構件而形成即可，則其構成並無限制。The leg gathers may be formed by forming a plurality of leg elastic members that are vertically and vertically held by the leg gathers and arranged in the width direction, and the configuration is not limited.
例如，亦可將腿皺褶形成片體於寬度方向外側自下表面側向寬度方向內側折返而形成2層區域，於如此而形成之2層區域內夾持腿彈性構件，而形成腿皺褶。For example, the leg gathers sheet may be folded back from the lower surface side toward the inner side in the width direction on the outer side in the width direction to form a two-layered region, and the leg elastic members are sandwiched in the two-layered region thus formed to form the leg gathers. .
又，腿皺褶形成片體8，如圖9所示，可將2片片體於其等之寬度方向外側之端部8A處藉由端部接合部74接合，而形成2層區域82，且可於如此而形成之2層區域82中夾持腿彈性構件52而構成腿皺褶51。Further, the leg gathers form the sheet body 8, and as shown in Fig. 9, the two sheets can be joined by the end joint portion 74 at the end portion 8A on the outer side in the width direction thereof to form a two-layered region 82. The leg elastic members 52 can be sandwiched in the two-layer region 82 thus formed to constitute the leg gathers 51.
腿皺褶形成片體亦可不由外層片體形成，例如，可由背面片體形成。The leg gathers may not be formed from the outer sheet, for example, may be formed from the back sheet.
被覆片體亦可不由立體皺褶形成用之片體形成，例如，可由正面片體形成，又，立體皺褶形成用之片體或正面片體等可由其他片體形成。The coated sheet may not be formed of a sheet for forming a three-dimensional gather, and may be formed, for example, by a front sheet, and a sheet for forming a three-dimensional gather or a front sheet may be formed of another sheet.
腿彈性構件、立體皺褶形成用彈性構件、腰彈性構件之條數、形狀等可適宜變更。The number of the leg elastic members, the elastic members for forming the three-dimensional gathers, the number of the waist elastic members, the shape, and the like can be appropriately changed.
本發明並非限制於嬰幼兒用丟棄式尿褲，亦可適用於成人用丟棄式尿褲。又，本發明並非限制於展開型之丟棄式尿褲，亦可適用於短褲型丟棄式尿褲。The present invention is not limited to disposable diapers for infants and children, and can also be applied to disposable diapers for adults. Further, the present invention is not limited to the unfolded disposable diaper, and can also be applied to a pants-type disposable diaper.
