[專利文獻1]日本特開2004-65929號公報 [Patent Document 1] Japanese Patent Laid-Open Publication No. 2004-65929
因為專利文獻1所揭示之吸收性物品係為具備：在厚壁部中局部性具有高吸收容量的吸收構造體者，因此藉由將該厚壁部配置在體液***比較多的區域，可以充分發揮其吸收性能。又，在該吸收構造體中，因為在體液***比較少量的區域形成薄壁部，因此可以說是吸收效率優。 The absorbent article disclosed in Patent Document 1 is provided with an absorbent structure having a high absorption capacity locally in the thick portion. Therefore, the thick portion can be sufficiently disposed in a region where the body fluid is discharged more frequently. Play its absorption performance. Further, in the absorbent structure, since the thin portion is formed in a relatively small amount of body fluid excretion, it can be said that the absorption efficiency is excellent.
但是，因為在厚壁部與薄壁部的邊界中形成有段差，而有對於穿著用者造成不舒服感之虞，同時在穿著用時由於吸收構造體順著穿著用者的身體而彎曲，在段差部份中會局部性產生裂痕等，而有發生體液外漏之虞。又，即使在該段差為比較小的情況下，當位於***區域並被挾壓在穿著用者的大腿間的部份之剛性為比較低時，會使該部份變形而在吸收構造體整體產生裂痕，有發生體液外漏之虞。 However, since a step is formed in the boundary between the thick portion and the thin portion, the wearer feels uncomfortable, and at the same time, the wear structure bends along the wearer's body during wearing. In the step portion, cracks and the like are locally generated, and there is a flaw in the leakage of body fluid. Moreover, even in the case where the step is relatively small, when the rigidity of the portion located between the armpit region and being pressed between the wearer's thighs is relatively low, the portion is deformed to be in the absorbent structure. There is a crack in the whole, and there is a flaw in the leakage of body fluid.
本發明之課題係為提供一種藉由具有厚度不均的形狀而使吸收效率為優，而且，藉由局部性設置高剛性區域而不怕會產生在穿著用中誘發體液外漏之虞的彎折等之吸收構造體及使用該吸收構造體的吸收性穿著用物品。 An object of the present invention is to provide an absorption efficiency which is excellent by a shape having a thickness unevenness, and it is possible to provide a high-rigidity region locally without fear of causing a flaw in which a body fluid is leaked during wearing.

根據關於本案之1個以上的發明之吸收構造體，因為使厚度傾斜部位於厚壁部與薄壁部之間，不會產生根據急遽的厚度尺寸變化之段差。又，因為藉由進行薄壁部與厚度傾斜部的凹印加工而在與厚壁部之間沒有產生大的剛性差，因此不怕根據由於剛性變化或段差發生之部份性裂痕等而發生體液外漏乙事。再者，因為使施予形成有多數壓縮凹部之凹印加工的高剛性區域位於厚壁部之與厚度傾斜 部相鄰的部位，因此即使作用有挾壓該部位而使其變形的力量，也不怕會發生部份性的裂痕或撕裂。 According to the absorbent structure of one or more of the inventions of the present invention, since the thickness inclined portion is located between the thick portion and the thin portion, the step of changing the thickness dimension according to the rapid thickness does not occur. Further, since the rough processing is performed between the thin portion and the thickness inclined portion, a large rigidity difference does not occur between the thick portion and the thick portion, so that the body fluid does not occur due to a partial crack due to a change in rigidity or a step. Leaking a baffle. Furthermore, since the high-rigidity region to which the gravure process for forming the plurality of compression concave portions is applied is located at the thick portion and the thickness is inclined The adjacent part, so even if it exerts the force of deforming the part to deform it, it is not afraid of partial cracks or tears.
在具備該吸收構造體之吸收性穿著用物品中，藉由將吸收構造體的厚壁部位於***尿的前腰部區域及***區域而可以充分發揮其之吸收性能，同時因為薄壁部位於後腰部區域，提升對於穿著用者臀部的合身性，而且使吸收構造體整體的吸收效率為優。又，因為將形成在厚壁部之與厚度傾斜部相鄰的部位之高剛性區域位於***區域，因此即使該部份被挾壓在穿著用者的大腿間，也不怕會發生部份性的裂痕或撕裂。 In the absorbent article for wearing the absorbent structure, the absorbent portion can be sufficiently absorbed by the thick portion of the absorbent structure in the front waist region and the underarm region of the urine, and the thin portion is located at the same time. In the back waist region, the fit to the wearer's buttocks is improved, and the absorption efficiency of the entire absorbent structure is excellent.

當參照圖3~圖5時，在圖4中，以Z表示吸收構造體17的厚度方向，吸收構造體17係具有：位於前腰部區域11側的前方域(第1區域)51、位於後腰部區域12側的後方域(第2區域)52、及在前方域51及後方域52之間位於朝兩側緣17c、17d的內方之凹曲部22間的中央部53。吸收構造體17係使前方域51比後方域52更為厚壁，具體而言，具有：從前方域51延伸到後方域52的一部份之比較厚壁的厚壁部55、從厚壁部55朝向後方逐漸向吸收構造體17的底面側傾斜延伸之厚度傾斜部56、及從厚度傾斜部56延伸到後端緣17b之比厚壁部55的厚度尺寸更小的薄壁部57。又，在本實施形態中，吸收構造體17雖然是由朝縱方向Y連續延伸的一層加以形成的，但是以厚壁部55比薄壁部57更為厚壁的方式，將該區域形成為2層亦可，以多層形成包含薄壁部57之吸收構造 體17整體亦可。 3 to 5, in FIG. 4, the thickness direction of the absorbent structure 17 is indicated by Z, and the absorbent structure 17 has a front region (first region) 51 located on the front waist region 11 side, and is located rearward. The rear region (second region) 52 on the side of the waist region 12 and the central portion 53 between the front region 51 and the rear region 52 are located between the concave portions 22 on the inner side of the side edges 17c and 17d. The absorbing structure 17 is such that the front domain 51 is thicker than the rear domain 52, and specifically has a relatively thick thick portion 55 extending from the front domain 51 to the rear domain 52, and is thicker. The thickness portion 56 that gradually extends toward the bottom surface side of the absorbent structure 17 toward the rear side and the thin portion 57 that extends from the thickness inclined portion 56 to the rear end edge 17b are smaller than the thickness of the thick portion 55. Further, in the present embodiment, the absorbent structure 17 is formed by a layer extending continuously in the longitudinal direction Y. However, the thick portion 55 is thicker than the thin portion 57, and the region is formed as The two layers may also form an absorption structure including the thin portion 57 in multiple layers. The body 17 as a whole can also be used.
但是，在吸收構造體17整體為如本實施形態所示以單層加以形成的情況下，與以多層加以形成的情況相比，在吸收構造體17整體中，因為將被包含在其中之紙漿纖維與作為選項予以追加的熱可塑性纖維進行混纖，因此難以崩垮而保形性優。 However, when the entire absorbent structure 17 is formed as a single layer as in the present embodiment, the entire absorbent structure 17 is pulped to be contained therein as compared with the case where it is formed of a plurality of layers. Since the fiber is blended with the thermoplastic fiber added as an option, it is difficult to collapse and has excellent shape retention.
在以單層形成吸收構造體17的情況下，雖然可以使用既知的製造方法、製造裝置形成該形狀，但是例如可以利用以下的方法加以形成。 When the absorbing structure 17 is formed in a single layer, the shape can be formed by a known manufacturing method or manufacturing apparatus, but it can be formed, for example, by the following method.
在具有：由短纖木材紙漿及/或超吸收聚合物粒子形成之吸收材料的供給手段、及具有複數個凹狀模型之旋轉吸引滾筒之製造裝置中，透過移送管從供給手段將吸收材料收集在凹狀模型而形成堆疊體(吸收性芯片)。滾筒的凹狀模型係使其底部為具有複數個開孔的網狀，透過開孔而在凹狀模型內吸引收集吸收材料，凹狀模型的底部係以在堆疊體形成相當於厚壁部55、厚度傾斜部56、及薄壁部57的部份之方式，使深度尺寸(從板材表面到凹狀模型底部的分離尺寸)有所不同者。具體而言，在該深度尺寸之比較大的部份形成具有需要的厚度之吸收構造體17的厚壁部55，在深度尺寸之比較小的部位形成薄壁部57，再者，在位於兩者之間的傾斜部位形成厚度傾斜部56。 In a manufacturing apparatus having an absorbent material formed of short-fiber wood pulp and/or superabsorbent polymer particles and a rotary suction drum having a plurality of concave molds, the absorbent material is collected from the supply means through the transfer pipe A stacked body (absorbent chip) is formed in a concave shape. The concave shape of the drum is such that the bottom is a mesh having a plurality of openings, and the absorbing material is attracted and collected in the concave mold through the opening, and the bottom of the concave model is formed to form a thick portion 55 in the stacked body. The thickness of the inclined portion 56 and the portion of the thin portion 57 are such that the depth dimension (the separation dimension from the surface of the sheet to the bottom of the concave mold) is different. Specifically, the thick portion 55 having the absorbent structure 17 having a desired thickness is formed in a portion having a relatively large depth dimension, and the thin portion 57 is formed at a portion having a relatively small depth dimension, and further, located at two The inclined portion between the persons forms a thickness inclined portion 56.
吸收構造體17係作為整體具有厚度不均的特異形狀 者，在前腰部區域11及***區域13中，可以利用具有需要的吸收容量之厚壁部55，確實吸收需要量的體液，主要是被***的尿液。又，因為在與前腰部區域11及***區域13相比在體液的***量為少的後腰部區域12側中使薄壁部57位於此處，在吸收構造體17整體中幾乎沒有不用於體液吸收的部位，並與習知之具有吸收容量一定的形狀、構造之吸收構造體相比，可以說是吸收效率優。再者，藉由將用於吸收構造體17之吸液性芯片的分量構成為必要最低限，可以抑制生產成本。 The absorbent structure 17 as a whole has a specific shape with uneven thickness In the front waist region 11 and the underarm region 13, the thick portion 55 having the required absorption capacity can be used to surely absorb the required amount of body fluid, mainly the excreted urine. In addition, since the thin portion 57 is located on the side of the rear waist region 12 where the amount of exudation of the body fluid is smaller than that of the front waist region 11 and the crotch region 13, there is almost no use in the entire absorbent structure 17 The site where the body fluid is absorbed is superior to the conventional absorbent structure having a shape and structure having a constant absorption capacity. Furthermore, by making the component of the liquid-absorbent chip for absorbing the structure 17 a necessary minimum, the production cost can be suppressed.
藉由形成厚度傾斜部56、及薄壁部57，在後方域52中因為朝向後方構成為比較薄壁，因此後腰部區域12係順著穿用者的身體形狀而易於變形合身，可以提升穿著感。再者，藉由使尿布10整體的厚度變小，在以前後腰部區域11、12相互重疊的方式將尿布10折成2折進行收納時不會變得龐大，在收納於包裝封包等時提升收納性。 By forming the thickness inclined portion 56 and the thin portion 57, since the rear region 52 is formed to be relatively thin toward the rear, the rear waist region 12 is easily deformed and fitted along the shape of the wearer's body, and can be worn up. sense. Further, by reducing the thickness of the entire diaper 10, the diaper 10 is folded into two folds so that the diaper 10 is folded into two folds when the front and rear waist regions 11 and 12 overlap each other, and does not become bulky, and is lifted when stored in a package or the like. Storage.
在吸收構造體17中，將厚壁部55與薄壁部57直接連續鄰接的情況下，不只是根據該急遽的厚度尺寸變化之剛性差、及根據厚壁部55與薄壁部57之間的段差形成造成穿著用者的不舒服感之虞，也會有在該邊界附近造成吸收構造體17的一部份彎折、扭歪而誘發體液的外漏之虞。但是，在本實施形態中，藉由在厚壁部55與薄壁部57之間形成厚度傾斜部56，可以使厚度尺寸平緩變化，因為沒有形成根據急遽的厚度尺寸變化之剛性差及段差，因此不怕對於穿著用者造成該不舒服感，又，在各部 55、56、57的邊界附近中也不怕會發生誘發體液外漏之彎折、扭歪。 In the absorbent structure 17, when the thick portion 55 and the thin portion 57 are directly adjacent to each other, not only the difference in rigidity depending on the thickness of the sudden thickness but also between the thick portion 55 and the thin portion 57 The formation of the step is caused by the uncomfortable feeling of the wearer, and there is also a possibility that a part of the absorbing structure 17 is bent and twisted in the vicinity of the boundary to induce leakage of the body fluid. However, in the present embodiment, by forming the thickness inclined portion 56 between the thick portion 55 and the thin portion 57, the thickness dimension can be changed gently, because the rigidity difference and the step difference due to the rapid thickness dimension are not formed. Therefore, I am not afraid of causing this discomfort to the wearer, and In the vicinity of the boundary of 55, 56, and 57, it is not afraid that bending and twisting of the leakage of body fluid will occur.
當參照圖5時，薄壁部57係形成在不會阻礙吸收構造體17的吸收性能之區域，即，不太***體液的區域為佳。具體而言，薄壁部57係以位於後腰部區域12側，並對於吸收構造體17整體的面積而言具有大約40%程度的大小為佳。又，厚度傾斜部56係為了達到根據急遽的厚度梯度變化產生剛性差及段差而對於穿著用者不會造成不舒服感，在吸收構造體17的縱方向Y的長度尺寸L1為約320~450mm的情況中，其縱方向Y的長度尺寸L2以約25~70mm為佳，以約35~60mm為更佳。在厚度傾斜部56之縱方向Y的長度尺寸L2為約25mm以下的情況下，對於厚壁部55與薄壁部57之厚度尺寸差的緩和高度梯度之長度為不夠，而在薄壁部57與厚度傾斜部56之邊界附近會形成段差，而有對於穿著用者造成不舒服感之虞。又，在厚度傾斜部56之縱方向Y的長度尺寸L2為70mm以上的情況下，使對於吸收構造體17整體之厚壁部55的形成區域變小，而有損害所謂根據設置厚壁部55之體液吸收容量的確保之本實施形態的效果之虞。 When referring to Fig. 5, the thin portion 57 is formed in a region where the absorption performance of the absorbent structure 17 is not hindered, that is, a region where the body fluid is not excreted is preferable. Specifically, the thin portion 57 is located on the side of the rear waist region 12, and preferably has a size of about 40% with respect to the entire area of the absorbent structure 17. Further, the thickness inclined portion 56 does not cause an uncomfortable feeling to the wearer in order to cause a difference in rigidity and a step due to a sudden change in the thickness gradient, and the length L1 in the longitudinal direction Y of the absorbent structure 17 is about 320 to 450 mm. In the case of the longitudinal direction, the length L2 of the longitudinal direction Y is preferably about 25 to 70 mm, more preferably about 35 to 60 mm. When the length dimension L2 of the thicknesswise inclined portion 56 in the longitudinal direction Y is about 25 mm or less, the length of the relaxation height gradient of the difference in thickness between the thick portion 55 and the thin portion 57 is insufficient, and in the thin portion 57. A step is formed in the vicinity of the boundary of the thickness inclined portion 56, and there is a feeling of discomfort to the wearer. In the case where the length L2 of the thicknesswise inclined portion 56 in the longitudinal direction Y is 70 mm or more, the formation region of the thick portion 55 of the entire absorbent structure 17 is made small, and the thick portion 55 is provided in accordance with the thickness. The effect of the present embodiment is ensured by the body fluid absorption capacity.
針對吸收構造體17的各區域55、56、57的形成而言，可以分別由厚壁部55之厚度尺寸為約2.7~3.3mm，吸液性芯片為質量約220~260g/m2的紙漿纖維及質量約180~220g/m2的SAP之混合物，就薄壁部56而言，厚度尺寸為約2.2~2.8mm，吸液性芯片為質量約180~ 220g/m2的紙漿纖維及質量約140~180g/m2的SAP之混合物等加以形成。換言之，與厚壁部55相比薄壁部57的每單位面積質的質量為低，具體而言，為了達到本發明之前述效果，薄壁部57之吸液性芯片的每單位面積的質量為厚壁部55的每單位面積的質量之約50~85%的範圍內為佳。 For the formation of the respective regions 55, 56, 57 of the absorbent structure 17, the thickness of the thick portion 55 may be about 2.7 to 3.3 mm, and the liquid-absorbent chip may be a pulp having a mass of about 220 to 260 g/m 2 . A mixture of fibers and SAP having a mass of about 180 to 220 g/m 2 has a thickness of about 2.2 to 2.8 mm for the thin portion 56 and a pulp fiber of about 180 to 220 g/m 2 for the liquid-absorbent chip. A mixture of SAP of about 140 to 180 g/m 2 or the like is formed. In other words, the mass per unit area of the thin portion 57 is lower than that of the thick portion 55. Specifically, in order to achieve the aforementioned effects of the present invention, the mass per unit area of the liquid-absorbent chip of the thin portion 57 is obtained. It is preferably in the range of about 50 to 85% of the mass per unit area of the thick portion 55.
吸收構造體17之各區域的厚度尺寸係可以使用厚度測量器(PEACOCK公司製、測量壓：12.5g/cm2)進行測量。具體而言，厚壁部55及薄壁部57之厚度係從尿布10取出吸收構造體17，並在相當於該厚壁部55與薄壁部57的部份中分別裁切出縱方向Y的長度尺寸約50mm×橫方向X的長度尺寸約50mm的大小作為試料，利用厚度測量器測量該試料中央部的厚度。 The thickness dimension of each region of the absorbent structure 17 can be measured using a thickness measuring device (manufactured by PEACOCK Co., Ltd., measuring pressure: 12.5 g/cm 2 ). Specifically, the thickness of the thick portion 55 and the thin portion 57 is taken out from the diaper 10, and the longitudinal direction Y is cut out in the portion corresponding to the thick portion 55 and the thin portion 57, respectively. The length dimension of the specimen was about 50 mm × the length dimension of the transverse direction X was about 50 mm, and the thickness of the center portion of the sample was measured by a thickness gauge.
當參照圖4時，在吸收構造體17的後方域52中，設置：在薄壁部57中使複數個壓縮凹部60向吸收構造體17的縱方向Y觀看配置為約略鋸齒狀之第1凹印加工部61、及在厚度傾斜部56及與厚度傾斜部56相鄰之厚壁部55中使複數個壓縮凹部60向吸收構造體17的縱方向Y觀看配置為約略鋸齒狀之第2凹印加工部63。藉由設置第1及第2凹印加工部61、63，薄壁部57、厚度傾斜部56及該相鄰部位係在與沒有施予凹印加工的情況相比，使剛性變高。在厚壁部55之形成有第2凹印加工部63之該相鄰部位與厚壁部55之其他部份相比剛性為高，在吸收構造體17中形成剛性最高的高剛性區域64。 Referring to Fig. 4, in the rear region 52 of the absorbent structure 17, a plurality of compressed concave portions 60 are disposed in the thin portion 57 so as to be arranged in the longitudinal direction Y of the absorbent structure 17 in a first jagged shape. In the printed portion 61 and the thick portion 55 adjacent to the thickness inclined portion 56 and the thick portion 55 adjacent to the thickness inclined portion 56, the plurality of compressed concave portions 60 are arranged in the longitudinal direction Y of the absorbent structure 17 so as to be arranged in a substantially zigzag-shaped second concave shape. Print processing unit 63. By providing the first and second gravure processing portions 61 and 63, the thin portion 57, the thickness inclined portion 56, and the adjacent portion are made higher in rigidity than in the case where the gravure processing is not performed. The adjacent portion of the thick portion 55 in which the second gravured portion 63 is formed is higher in rigidity than the other portion of the thick portion 55, and the highly rigid region 64 having the highest rigidity is formed in the absorbent structure 17.
如前述所示，在本實施形態中，雖然藉由調整吸收構造體17的厚度而形成吸收容量不同的區域，但是在厚度有所變化的部位中恐怕會產生剛性差。為了將該剛性差變小，雖然在厚壁部55及薄壁部57之間形成有厚度傾斜部56，但是藉由形成第1及第2凹印加工部61、63而提高薄壁部57及厚度傾斜部56的剛性，可以進一步縮小其等與厚壁部55之剛性差，並且可以進一步防止吸收構造體17之根據部份性的裂痕之變形或型崩垮。 As described above, in the present embodiment, the regions having different absorption capacities are formed by adjusting the thickness of the absorbent structure 17, but there is a fear that a difference in rigidity occurs in a portion where the thickness is changed. In order to reduce the rigidity difference, the thickness inclined portion 56 is formed between the thick portion 55 and the thin portion 57. However, the thin portion 57 is formed by forming the first and second gravure portions 61 and 63. Further, the rigidity of the thickness inclined portion 56 can further reduce the rigidity difference between the thick portion 55 and the thick portion 55, and the deformation or the type collapse of the partial deformation of the absorbent structure 17 can be further prevented.
當參照圖4及圖5時，高剛性區域64係位於兩側緣17c、17d的屈曲部位24及其附近之間。屈曲部位24及其附近係為直狀部21及曲狀部22的交叉部分，在吸收構造體17中，其係為根據該形狀的變化或穿著用者的襠下動作而最容易產生裂痕或皺折、扭歪彎曲之處，即使是厚壁部55在與厚度傾斜部56及薄壁部57相比為具有高剛性，但是該區域的扭歪彎曲係波及到厚度傾斜部56及薄壁部57而使後方域52整體與穿著用者的身體分離，有誘發體液外漏之虞。又，吸收構造體17的曲狀部22雖然是以在穿著用狀態中順著穿著用者的大腿而合身的方式具有曲狀者，但是在穿著用者為比較高月齡的幼兒之情況下，屈曲部位24及比其更後方的部位係被挾壓在大腿間，而作用有使其變形的力量。在本實施形態中，藉由在該區域設置在吸收構造體17中具有最高剛性的高剛性區域64，防止以屈曲部位24為起點之扭歪彎曲，而可以防止後方域52整體與穿著用者的身體分離。 Referring to Figures 4 and 5, the high stiffness region 64 is located between the flexure 24 of the side edges 17c, 17d and its vicinity. The flexure portion 24 and its vicinity are the intersections of the straight portion 21 and the curved portion 22, and in the absorbent structure 17, the crack is most likely to occur depending on the shape change or the wearer's underarm motion. In the case of wrinkles and twists and turns, even if the thick portion 55 has high rigidity as compared with the thickness inclined portion 56 and the thin portion 57, the torsional bending of the region spreads to the thickness inclined portion 56 and the thin wall. The portion 57 separates the entire rear region 52 from the wearer's body, and causes a leakage of body fluid. In addition, the curved portion 22 of the absorbent structure 17 has a curved shape so as to fit along the wearer's thigh in the wearing state, but in the case where the wearer is a child of a relatively high age, the buckling is performed. The portion 24 and the portion behind it are pressed between the thighs and exert a force to deform it. In the present embodiment, by providing the high-rigidity region 64 having the highest rigidity in the absorbent structure 17 in this region, the torsion bending starting from the flexion portion 24 is prevented, and the rear region 52 as a whole can be prevented from being worn by the wearer. The body is separated.
作為形成高剛性區域64的方法，例如可以設計為局部性提高吸液性芯片的每單位面積的質量而使該區域成為最厚壁，但是在該情況下，使該區域像是肋骨般作用而使吸收構造體17整體難以順著穿著用者的身體形狀彎曲，有合身感降低之虞。在本實施形態的情況下，因為利用施予凹印加工之第2凹印加工部63而畫出高剛性區域64，可以抑制以該區域附近為起點之裂痕或變形，另一方面可以使吸收構造體17順著穿著用者的身體形狀彎曲，而可以實現根據變形等之體液外漏的防止、及對於穿著用者的身體之合身性的確保。 As a method of forming the high-rigidity region 64, for example, it is possible to locally increase the mass per unit area of the liquid-absorbent chip to make the region the thickest wall, but in this case, the region acts like a rib. It is difficult for the entire absorbent structure 17 to be bent along the body shape of the wearer, and the fit is lowered. In the case of the present embodiment, since the high-rigidity region 64 is drawn by the second gravure processing portion 63 to which the gravure processing is applied, cracks or deformations starting from the vicinity of the region can be suppressed, and absorption can be suppressed on the other hand. The structure 17 is bent along the body shape of the wearer, and it is possible to prevent the leakage of the body fluid due to deformation or the like and to ensure the fit of the wearer's body.
形成第1及第2凹印加工部61、63的複數個壓縮凹部60係具有大約相同尺寸的約圓形狀，在第1凹印加工部61中配置為比較緊密，在第2凹印加工部63中配置為比較稀疏。因此，以第1凹印加工部61作為整體之壓縮凹部60的總面積率係比以第2凹印加工部63作為整體之壓縮凹部60的總面積率更高。具體而言，對於前者的壓縮凹部60之總面積率為約12~18%而言，後者的壓縮凹部60之總面積率為約5.0~9.0%。又，壓縮凹部60之厚度方向Z中的長度尺寸(深度)係為約0.2~0.5mm。 The plurality of compression recesses 60 forming the first and second gravure processing portions 61 and 63 have approximately circular shapes of approximately the same size, and are disposed relatively tightly in the first gravure processing portion 61, and are disposed in the second gravure processing portion. 63 is configured to be sparse. Therefore, the total area ratio of the compressed concave portion 60 as a whole of the first gravure processed portion 61 is higher than the total area ratio of the compressed concave portion 60 as a whole of the second gravure processed portion 63. Specifically, the total area ratio of the compressed recess 60 of the former is about 12 to 18%, and the total area ratio of the compressed recess 60 of the latter is about 5.0 to 9.0%. Further, the length dimension (depth) in the thickness direction Z of the compression concave portion 60 is about 0.2 to 0.5 mm.
藉由使第1凹印加工部61之壓縮凹部60的總面積率比第2凹印加工部63之其更大，減低薄壁部57與厚度傾斜部56的剛性差，可以防止以其等邊界為起點之吸收構造體17的變形。又，在厚度梯度部56中，因為在薄壁部57側的部位設置第1凹印加工部61，在比該部位更厚的 厚壁部55側的部位設置第2凹印加工部63，因此即使在厚度傾斜部56內也不會使剛性急遽變化，可以防止以厚度傾斜部56為起點之吸收構造體17的變形或彎折。 By making the total area ratio of the compressed concave portion 60 of the first gravure processing portion 61 larger than that of the second gravure processing portion 63, the rigidity difference between the thin portion 57 and the thickness inclined portion 56 can be reduced, thereby preventing the like. The deformation of the absorbent structure 17 starting from the boundary. Further, in the thickness gradient portion 56, since the first gravure processing portion 61 is provided on the portion on the thin portion 57 side, it is thicker than the portion. Since the second gravured portion 63 is provided in the portion on the side of the thick portion 55, the rigidity does not change sharply in the thickness inclined portion 56, and deformation or bending of the absorbent structure 17 starting from the thickness inclined portion 56 can be prevented. fold.
當參照圖4時，在第1及第2凹印加工部61、63中係形成在橫方向X連續延伸之没有設置壓縮凹部60的非壓縮部。藉由形成非壓縮部而使吸收構造體17具有需要的柔軟性，藉由至少在第2凹印加工部63形成非壓縮部，使厚度傾斜部56及高剛性區域64易於順著穿著用者的身體彎曲。只要達成前述效果的情形下，第1及第2凹印加工部61、63之壓縮凹部60的總面積率之值係可以適當變更，作為凹印圖案除了千鳥格狀之外採用各種既知的圖案亦可，針對壓縮凹部60的形狀也是，圓形以外也可以是具有橢圓形、菱形、長方形等各種既知的形狀者。 Referring to Fig. 4, in the first and second gravure processing portions 61, 63, an uncompressed portion in which the compression concave portion 60 is not continuously provided in the lateral direction X is formed. By forming the non-compressed portion, the absorbent structure 17 has the required flexibility, and the non-compressed portion is formed at least in the second gravure-processed portion 63, so that the thickness-inclined portion 56 and the high-rigidity region 64 are easily worn by the wearer. The body is bent. When the effect is achieved, the value of the total area ratio of the compressed concave portions 60 of the first and second gravure-processed portions 61 and 63 can be appropriately changed, and various known patterns can be used as the gravure pattern in addition to the houndstooth shape. The shape of the compression concave portion 60 may be any shape other than a circular shape such as an elliptical shape, a rhombus shape, or a rectangular shape.
當參照圖6時，透過搬送滾輪(未圖示)將與複數個吸收構造體17對應的部分而連續形成之連續吸收構造體71搬送到機械方向MD。連續吸收構造體71係為利用液芯搭接薄片封裝由單層或多層構成的吸液性芯片而被形成者，並使相當於各吸收構造體17的厚度傾斜部56及薄壁部57的部份71a朝下方凹陷而成為薄壁。 Referring to Fig. 6, the continuous absorbent structure 71 continuously formed in a portion corresponding to the plurality of absorbent structures 17 is conveyed to the machine direction MD by a conveyance roller (not shown). The continuous absorbent structure 71 is formed by encapsulating a liquid-absorbent chip composed of a single layer or a plurality of layers by a wicking sheet, and the thickness inclined portion 56 and the thin portion 57 corresponding to each of the absorbent structures 17 are formed. The portion 71a is recessed downward to become a thin wall.
當參照圖6及圖7時，為了在吸收構造體17賦予第1及第2凹印加工部61、63之凹印工程係由：位於連續吸收構造體71的上方之朝一方向旋轉之凹印滾筒72、及 與其對向配置之朝向與凹印滾筒72的反方向旋轉之外周面為平滑的砧滾筒73加以構成。在凹印滾筒72之外周面的一部份中係具有第1端緣74a及第2端緣74b，並設置從第1端緣74a朝向第2端緣74b隨著朝周方向延伸逐漸變厚的***部74。***部74係進一步具有位於第1端緣74a側的薄壁部位75及位於第2端緣74b的厚壁部位76。在***部74表面及其第1端緣74a側的凹印滾筒72之外周面的一部份係突出有複數個輪轂77。輪轂77係區分為：形成在***部74的厚壁部位76之與各吸收構造體17的第1凹印加工部61對應之第1凹印群組78；及形成在薄壁部位75之與各吸收構造體17的第2凹印加工部63對應之比第1凹印群組78使輪轂77的分開尺寸更大，並配置為比較疏之第2凹印群組80。又，輪轂77係為了在連續吸收構造體71穩定形成壓縮凹部60，將構成其之薄片構件加熱到不會熔接的程度亦可。 Referring to Fig. 6 and Fig. 7, the gravure printing system for applying the first and second gravure-finished portions 61 and 63 to the absorbing structure 17 is a gravure that is rotated in one direction above the continuous absorbing structure 71. Roller 72, and The anvil cylinder 73 whose circumference is smooth and whose outer surface is rotated in the opposite direction to the gravure cylinder 72 is configured. A portion of the outer peripheral surface of the gravure cylinder 72 has a first end edge 74a and a second end edge 74b, and is provided to gradually thicken from the first end edge 74a toward the second end edge 74b as it extends in the circumferential direction. The ridge 74. The raised portion 74 further has a thin portion 75 on the side of the first end edge 74a and a thick portion 76 on the second end edge 74b. A plurality of hubs 77 are protruded from a portion of the outer peripheral surface of the embossing cylinder 72 on the surface of the ridge portion 74 and the first end edge 74a side thereof. The hub 77 is divided into a first gravure group 78 formed in the thick portion 76 of the raised portion 74 corresponding to the first gravured portion 61 of each of the absorbent structures 17, and a thin portion 75 formed in the thin portion 75. The second gravure processing portion 63 of each of the absorbing structures 17 corresponds to the first gravure group 78 to make the separation size of the hub 77 larger, and is arranged to be relatively thinner than the second gravure group 80. Further, the hub 77 is configured such that the compressed concave portion 60 is stably formed in the continuous absorbent structure 71, and the sheet member constituting the same is heated to such an extent that it is not welded.
凹印滾筒72係以將形成在其外周面的***部74與連續吸收構造體71之相當於厚度傾斜部56及薄壁部57的部份71a對向位置的方式，將其旋轉速度與連續吸收構造體71的搬送速度調整為同步，藉由使***部74之厚壁部位76的第1凹印群組78沖壓相當於薄壁部57的部位而形成第1凹印加工部61，藉由使***部74之薄壁部位75的第2凹印群組80沖壓相當於厚度傾斜部56及厚壁部55之高剛性區域64的部位而形成第2凹印加工部63。 The gravure cylinder 72 rotates the rotation speed and the continuous portion so that the raised portion 74 formed on the outer peripheral surface thereof faces the portion 71a of the continuous absorbent structure 71 corresponding to the thickness inclined portion 56 and the thin portion 57. The conveyance speed of the absorbing structure 71 is adjusted to be synchronized, and the first gravure group 78 of the thick portion 76 of the swelled portion 74 is pressed into a portion corresponding to the thin portion 57 to form the first embossed portion 61. The second gravure processing portion 63 is formed by pressing the second concave printing group 80 of the thin portion 75 of the raised portion 74 into a portion corresponding to the high-rigidity region 64 of the thickness inclined portion 56 and the thick portion 55.
根據該凹印工程，因為可以在一個凹印滾筒72形成 ***部74，同時將圖案不同之第1及第2凹印加工部61、63進行賦型。與對於各凹印加工部61、63使用不同的凹印滾筒的情況相比，有所謂製造工程簡易化。又，***部74係為因應連續吸收構造體71之被沖壓部份的形狀而具有不同厚度者，因此不必將厚度傾斜部56進行比較強的沖壓而使其剛性變高到必要以上，又，因為利用***部74的厚壁部位76沖壓薄壁部57，因此可以使薄壁部57具有需要的剛性，同時形成為薄壁。 According to the gravure process, it can be formed in a gravure cylinder 72 The raised portion 74 simultaneously shapes the first and second gravure processed portions 61 and 63 having different patterns. Compared with the case where a different gravure cylinder is used for each of the gravure processing portions 61 and 63, there is a so-called manufacturing process. Further, since the raised portion 74 has a different thickness depending on the shape of the portion to be pressed of the continuous absorbent structure 71, it is not necessary to press the thick inclined portion 56 relatively strongly to increase the rigidity to a level higher than necessary. Since the thin portion 57 is pressed by the thick portion 76 of the ridge portion 74, the thin portion 57 can have the required rigidity and be formed into a thin wall.
凹印工程係除了上述構成之外，在第1及第2凹印群組78、80中輪轂77的總面積率為相同，並使輪轂77的長度尺寸有所不同，換言之，與薄壁部57對應之第1凹印群組78之輪轂77的長度尺寸係比形成第2凹印群組80之輪轂77之長度尺寸更大，而可以附予更高剛性者亦可。又，使用具有不同凹印圖案之2個凹印滾筒，利用一方的凹印滾筒在相當於第1及第2凹印加工部61、63的範圍施予凹印加工，並利用另一方的凹印滾筒只在相當於第1凹印加工部61的部份再次施予凹印加工者亦可。 In addition to the above configuration, the gravure printing system has the same total area ratio of the hub 77 in the first and second gravure groups 78 and 80, and the length of the hub 77 is different, in other words, the thin portion. The length of the hub 77 of the first gravure group 78 corresponding to 57 is larger than the length of the hub 77 forming the second gravure group 80, and may be attached with higher rigidity. Further, two gravure cylinders having different gravure patterns are used, and one of the gravure cylinders is used for gravure processing in the range corresponding to the first and second gravure processing portions 61 and 63, and the other concave portion is used. The printing cylinder may be applied to the gravure processor only at the portion corresponding to the first gravure processing portion 61.
若是針對吸收構造體17的厚壁部55、薄壁部57之各彎曲剛性而言，厚壁部55之中的高剛性區域64以外的區域中之彎曲剛性約為0.07~0.14N，高剛性區域64的彎曲剛性約為0.09~0.2N，薄壁部57的彎曲剛性約為0.04~0.07N。厚壁部55與薄壁部57之剛性值差為約0.04N 以下為佳。在剛性值為0.04N以上的情況，即使設置了用以緩和剛性的急遽變化之厚度傾斜部56，根據該剛性值之大差異，會使吸收構造體17變形而有部份性產生裂痕之虞。又，在高剛性區域64的剛性值為0.2N以上的情況，使吸收構造體17整體中之該區域的剛性值比其他區域更高，而有以其處為起點在吸收構造體17產生裂痕、變形之虞。 In the bending rigidity of the thick portion 55 and the thin portion 57 of the absorbent structure 17, the bending rigidity in the region other than the high rigidity region 64 among the thick portions 55 is about 0.07 to 0.14 N, and the rigidity is high. The bending rigidity of the region 64 is about 0.09 to 0.2 N, and the bending rigidity of the thin portion 57 is about 0.04 to 0.07 N. The difference in rigidity between the thick portion 55 and the thin portion 57 is about 0.04N. The following is better. In the case where the rigidity value is 0.04 N or more, even if the thickness inclined portion 56 for mitigating the rapid change in rigidity is provided, the absorption structure 17 is deformed and the crack is partially generated depending on the difference in the rigidity value. . Further, when the rigidity value of the high-rigidity region 64 is 0.2 N or more, the rigidity value of the region in the entire absorbent structure 17 is higher than that of the other regions, and cracks are generated in the absorbent structure 17 at the starting point. The deformation of the shackles.
吸收構造體17的厚壁部55與薄壁部57之各彎曲剛性係可以使用塔柏式挺度測試機進行測量。具體而言，從尿布10取出吸收構造體17，在厚壁部55及薄壁部57中作出切斷為縱方向Y的長度尺寸約70mm×橫方向X的長度尺寸約38.1mm的大約矩形的試料，並使用前述測試機以橫方向X彎曲的方式測量各部的塔柏彎曲剛性值。但是，針對厚壁部55的高剛性區域64係因為不具有前述測量尺寸的大小，因此使用具有比其等測量尺寸更小之需要的大小的試料，測量彎曲剛性。 The bending rigidity of the thick portion 55 and the thin portion 57 of the absorbent structure 17 can be measured using a Taber stiffness tester. Specifically, the absorbent structure 17 is taken out from the diaper 10, and the thick portion 55 and the thin portion 57 are formed into an approximately rectangular shape having a length dimension of about 70 mm in the longitudinal direction Y and a length dimension of about 38.1 mm in the lateral direction X. The sample was measured, and the Tabel bending rigidity value of each portion was measured by bending in the lateral direction X using the aforementioned tester. However, since the high-rigidity region 64 of the thick portion 55 does not have the above-described measurement size, a sample having a size smaller than the measurement size is measured, and the bending rigidity is measured.
吸收構造體17之厚壁部、厚度傾斜部、及薄壁部55、56、57各部的區分係例如可以利用以下的方法加以實施。又，以下的方法係為在吸收構造體17上施予凹印 加工前，而且不是根據各部的厚度尺寸而是根據每單位面積的質量算出的結果者。此係因為在施予凹印加工的前後中各部55、56、57的每單位面積的質量不會有所變化，又，如前述所示因應厚度尺寸也會使每單位面積的質量有所不同者，因此其係意指藉由單一的該方法就可以進行各部55、56、57的區分。 The thick portion of the absorbent structure 17, the inclined portion of the thickness, and the division of each of the thin portions 55, 56, and 57 can be carried out, for example, by the following method. Further, the following method is to apply gravure printing on the absorbent structure 17. Before the processing, it is not based on the thickness of each part but the result calculated based on the mass per unit area. This is because the mass per unit area of each of the portions 55, 56, 57 does not change before and after the application of the gravure processing, and the quality per unit area is also different depending on the thickness dimension as described above. Therefore, it means that the distinction between the parts 55, 56, 57 can be performed by a single method.
首先，將縱方向Y的長度尺寸約為360mm的吸收構造體17依照每個縱方向Y的長度尺寸約為20mm分割為18。其次測量被分割之每個各區段之每單位面積的質量(g/m2)。在各區段之中，將每單位面積的質量最高的區段之質量值成為1，並對於每個其他區段算出對於最大質量值的比例，對於1~18各區段在依序並列的表畫出曲線。在畫出曲線的各點之中，將連結兩側相鄰的點之線為都成為向下傾斜的2點作為邊界點，在厚壁側(對於最大質量值為比例值為高側)的邊界點為厚壁部55與厚度傾斜部56之邊界的第1邊界點，在薄壁側(對於最大質量值為比例值為低側)的邊界點為厚度傾斜部56與薄壁部57之邊界的第2邊界點。藉此，在吸收構造體17中，可以將表示各邊界點之各區段間的長度尺寸之區域作為厚度傾斜部56，比第1邊界點的區段更向厚壁側作為厚壁部55，比第2邊界點的區段更向薄壁部57側作為薄壁部57進行區分。 First, the absorbing structure 17 having a length dimension of about 360 mm in the longitudinal direction Y is divided into 18 in accordance with the length dimension of each longitudinal direction Y of about 20 mm. Next, the mass per unit area (g/m 2 ) of each of the divided sections is measured. Among the segments, the mass value of the segment with the highest quality per unit area is set to 1, and the ratio for the maximum mass value is calculated for each of the other segments, and the segments of 1 to 18 are sequentially juxtaposed. The table draws the curve. Among the points in which the curve is drawn, the line connecting the adjacent points on both sides is defined as two points which are downwardly inclined as the boundary point, and on the thick wall side (for the maximum quality value, the ratio is the high side) The boundary point is the first boundary point between the thick portion 55 and the thickness inclined portion 56, and the boundary point on the thin side (the lower side of the maximum mass value) is the thickness inclined portion 56 and the thin portion 57. The second boundary point of the boundary. Thereby, in the absorbent structure 17, the region indicating the length dimension between the respective segments of each boundary point can be regarded as the thickness inclined portion 56, and the thicker portion is thicker than the segment of the first boundary point. The section of the second boundary point is distinguished from the section of the second boundary point as the thin portion 57 as the thin portion 57.
當參照圖8，針對與第1實施形態不同之點進行闡述時，在本實施形態中，其係為使第1凹印加工部61之壓縮凹部的配置圖案與第2凹印加工部63之其有所不同者，在第1凹印加工部61中，使壓縮凹部60不存在之非壓縮部沒有在縱方向Y及橫方向X連續形成。為此，在第1凹印加工部61中，可以提高薄壁部57之全方向的剛性。如壓縮凹部60的配置圖案的一部份擴大圖所示，在第1凹印加工部61中，畫定複數個被6個壓縮凹部60所包圍的非壓縮部82。非壓縮部82係藉由被壓縮凹部60包圍而具有比較柔軟性，在與如實施形態1所示將壓縮凹部60配置為緊密的情況相比，可以提升對於穿著用者的身體之緩衝性。 Referring to Fig. 8, when the difference from the first embodiment is described, in the present embodiment, the arrangement pattern of the compressed concave portion of the first gravure processing portion 61 and the second concave printed portion 63 are used. In the first gravure processing portion 61, the non-compressed portion in which the compression concave portion 60 does not exist is not continuously formed in the longitudinal direction Y and the lateral direction X. Therefore, in the first gravure processing portion 61, the rigidity of the thin portion 57 in all directions can be improved. As shown in a partially enlarged view of the arrangement pattern of the compressed concave portion 60, in the first gravure processing portion 61, a plurality of uncompressed portions 82 surrounded by the six compressed concave portions 60 are drawn. The non-compressed portion 82 is relatively flexible by being surrounded by the compressed concave portion 60, and the cushioning property to the wearer's body can be improved as compared with the case where the compressed concave portion 60 is placed tight as in the first embodiment.
當參照圖9、圖10，針對與第1實施形態不同之點進行闡述時，在本實施形態中，吸收構造體17係具有：從前方域51延伸到中央部53的後方之第1厚壁部55A；形成在後方域52之薄壁部57；位於第1厚壁部55A與薄壁部57之間之厚度傾斜部56；位於薄壁部57與吸收構造體17的後端緣17b之間的第2厚壁部55B。 Referring to Fig. 9 and Fig. 10, when the point is different from the first embodiment, in the present embodiment, the absorbent structure 17 has a first thick wall extending from the front field 51 to the rear of the center portion 53. a portion 55A; a thin portion 57 formed in the rear region 52; a thickness inclined portion 56 located between the first thick portion 55A and the thin portion 57; and a thin portion 57 and a rear end edge 17b of the absorbent structure 17 The second thick portion 55B between.
第2厚壁部55B係為具有與第1厚壁部55A大約相等的厚度尺寸、或是至少是薄壁部57的1.1倍以上的厚度尺寸者，並且沒有形成第1凹印加工部61。如此一來，藉由在後方域52的後端緣17b側形成具有與第1厚 壁部55A大約相等的厚度尺寸之第2厚壁部55B，在第2厚壁部55B中可以吸收、保持無法利用薄壁部57充分吸收的體液，而可以確實防止從後端緣17b之體液外漏。 The second thick portion 55B has a thickness dimension approximately equal to that of the first thick portion 55A or a thickness of at least 1.1 times the thickness of the thin portion 57, and the first gravure processed portion 61 is not formed. In this way, the first thick layer is formed on the side of the rear end edge 17b of the rear domain 52. The second thick portion 55B having the thickness portion of the wall portion 55A is approximately equal in thickness, and the second thick portion 55B can absorb and hold the body fluid that cannot be sufficiently absorbed by the thin portion 57, and can reliably prevent the body fluid from the rear end edge 17b. External leakage.
