Description

吸收性物品Absorbent articles

本發明是關於吸收性物品。The present invention relates to absorbent articles.

就吸收性物品的一例可舉用後即棄式紙尿布。在專利文獻1揭示有用後即棄式紙尿布，其在吸收體的寬邊方向中央部具有口袋，該口袋是由比起周圍吸收素材基重低的低基重部及不具吸收素材的無基重部的至少一方形成，在吸收體與液不透過性薄片之間，將藉由與***液成分的接觸而變色的***顯示部以與非口袋部重疊的方式作設置。又，在專利文獻2揭示有吸收性物品，其是在吸收性芯與裏面薄片之間的預定部位配置與水分接觸就產生視覺變化的親水性的組成物，對應配置有組成物的部位，在吸收性芯設置比其他的部位更吸收容量小的部位。 [先前技術文獻] [專利文獻]An example of an absorbent article can be disposable paper diapers. Patent Document 1 discloses a disposable disposable diaper, which has a pocket in the center of the widthwise direction of the absorbent body. The pocket is composed of a low basis weight portion with a lower basis weight than the surrounding absorbent material and a non-basis weight portion without absorbent material. At least one of the parts is formed, and between the absorbent body and the liquid-impermeable sheet, the excretion display part that changes color by contact with the excretion liquid component is provided so as to overlap the non-pocket part. In addition, Patent Document 2 discloses an absorbent article in which a hydrophilic composition that changes visually upon contact with moisture is arranged at a predetermined position between the absorbent core and the back sheet, and corresponds to the position where the composition is arranged. The absorbent core is provided with a portion having a smaller absorption capacity than other portions. [Prior Technical Literature] [Patent Literature]

[專利文獻1]日本特開2010-75464號公報 [專利文獻2]日本特開2005-21390號公報[Patent Document 1] JP 2010-75464 A [Patent Document 2] JP 2005-21390 A

[發明所欲解決之課題][The problem to be solved by the invention]

可是，在專利文獻1的用後即棄式紙尿布，因為***顯示部被配置在由位於吸收體的低基重部或無基重部形成的口袋部的側部的非口袋部，所以，排尿時，雖然尿透過吸收體可到達***顯示部，可是，排便時，由於糞便的黏性高，所以，要透過吸收體的高基重部有困難，會有無法到達***顯示部的顧慮。However, in the disposable paper diaper of Patent Document 1, the excretion display portion is arranged in a non-pocket portion located on the side of the pocket portion formed by the low basis weight portion or the non-basis weight portion of the absorbent body, so, During urination, although the urine can pass through the absorber to reach the excretion display part, during defecation, because of the high viscosity of stool, it is difficult to pass through the high basis weight part of the absorber, and there is a concern that it cannot reach the excretion display part.

又，在專利文獻2的吸收性物品，對應比其他部位更吸收容量小的低吸收部被配置的組成物因為是親水性的組成物，所以，既會對尿中的水分，又會對糞便中的水分產生反應，而無法從吸收性物品的外面區別***了尿或糞便的哪一種。又，先進行排尿而使組成物產生了反應時，對於之後的排便，反應就變的困難，會有不能偵測排便的可能性。In addition, in the absorbent article of Patent Document 2, the composition arranged corresponding to the low-absorbent portion having a lower absorption capacity than other parts is a hydrophilic composition, so it will affect both the moisture in the urine and the feces. The moisture in the absorbent product reacts, and it is impossible to distinguish which of urine or feces is excreted from the outside of the absorbent article. In addition, when the composition reacts by urinating first, the reaction becomes difficult for subsequent defecation, and there is a possibility that defecation cannot be detected.

本發明，是有鑑於上述這樣的以往的問題所研發者，其目的在提供，可使糞便的水分順暢地透過吸收體，讓糞便的水分到達糞便顯示部的吸收性物品。 [解決課題用的手段]The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to provide an absorbent article that allows the moisture of feces to smoothly permeate the absorber and allows the moisture of feces to reach the feces display portion.

The target belt piece 29 is a member that can be engaged with the buckle 30, and is formed of, for example, a non-woven fabric. The target belt piece 29 constitutes a target area where the buckle belt 30 is engaged. In addition, instead of arranging the target tape 29 on the non-skin side of the back sheet 23, the target area may be directly formed on the nonwoven fabric constituting the outermost layer of the back sheet 23. Furthermore, by engaging the buckle 30 with the target belt piece 29, the paper diaper 1 is formed.

本實施形態的紙尿布1，是在紙尿布1的寬邊方向的中央部具有糞便顯示部40，又相對於糞便顯示部40遠離寬邊方向外側設有一對的尿顯示部50(參照圖1)。糞便顯示部40及尿顯示部50在厚度方向分別被配置在吸收體21的非肌膚側。尿顯示部50作為含有被以往一般的紙尿布所採用的pH指示藥的顯示部被構成。例如，尿顯示部50是以尿的pH作為反應因子(尿顯示反應因子)，藉由與尿接觸而呈現預定的反應(例如顯色反應)來偵測被排出尿的情況。關於糞便顯示部40的詳細容後敘述。The paper diaper 1 of this embodiment has a stool display portion 40 at the center of the width direction of the paper diaper 1, and a pair of urine display portions 50 are provided on the outer side away from the stool display portion 40 in the width direction (see FIG. 1 ). The stool display section 40 and the urine display section 50 are respectively arranged on the non-skin side of the absorber 21 in the thickness direction. The urine display unit 50 is configured as a display unit containing a pH indicator drug used in conventional general paper diapers. For example, the urine display unit 50 uses the pH of urine as a response factor (urinary display response factor), and presents a predetermined response (such as a color reaction) by contacting the urine to detect the state of being excreted. The details of the stool display section 40 will be described later.

＜糞便顯示部40的原理＞ 糞便顯示部40為紙尿布1等的吸收性物品用的糞便顯示部，藉由與糞便中所含的預定的反應因子(糞便顯示反應因子)接觸而呈現預定的反應(例如顯色反應)來偵測被排出糞便的情況。在本實施形態，糞便顯示部40包含偵測糞便中的生物物質的化學成分，藉由該化學成分對糞便的反應、與對尿的反應的不同，可以只檢測出糞便的排出。<Principle of the stool display unit 40> The stool display portion 40 is a stool display portion for absorbent articles such as a diaper 1, and exhibits a predetermined reaction (for example, a color reaction) by contacting a predetermined response factor (feces display reaction factor) contained in stool. Detect the condition of feces being discharged. In the present embodiment, the stool display unit 40 includes a chemical component for detecting biological substances in the stool, and the reaction of the chemical component to the stool is different from the reaction to the urine, so that only the discharge of the stool can be detected.

例如，偵測糞便顯示部40所含的化學成分的生物物質為蛋白質時，就該化學成分來說，使用pH指示藥為理想。一般，蛋白質具有胺基酸聚合的構造，因為在蛋白質的主鏈的兩末端、側鏈具有酸性及鹼性的官能基，所以，有一定以上的蛋白質存在時，可使pH指示藥變色(蛋白質誤差法)。在本實施形態，藉由偵測糞便中的來自食物的未消化的蛋白質、從腸內細菌所分泌的蛋白質等，使pH指示藥與糞便反應。就具體的pH指示藥來說，例如可使用四酚藍、溴酚藍、溴甲酚綠、百里酚酞等。再者，pH指示藥對肌膚安全，且是對濕氣、日光的保管性優者為期望。For example, when detecting that the biological substance of the chemical component contained in the stool display portion 40 is protein, it is ideal to use a pH indicator drug for the chemical component. Generally, a protein has a structure of amino acid polymerization. Because the protein has acidic and basic functional groups at both ends and side chains of the main chain, the presence of more than a certain amount of protein can cause the pH indicator to change color (protein Error method). In this embodiment, by detecting undigested protein from food, protein secreted from intestinal bacteria, etc. in feces, the pH indicator drug reacts with feces. For specific pH indicator drugs, for example, tetraphenol blue, bromophenol blue, bromocresol green, thymolphthalein, etc. can be used. Furthermore, it is desirable that the pH indicator drug is safe for the skin and has good storage properties against moisture and sunlight.

又，在糞便顯示部40為了不要對***物是糞便還是尿做出錯誤的檢測，而使糞便顯示部40所含的化學成分對糞便作反應，對尿不作反應為期望。於此，本實施形態中的糞便顯示部40是對預定濃度以上的糞便顯示反應因子(蛋白質等)作反應而顯示顯色反應等的反應，糞便顯示反應因子比預定濃度更小時，不易產生反應。In addition, in order not to erroneously detect whether the excrement is stool or urine, it is desirable that the chemical components contained in the stool display section 40 react to the stool and not to the urine. Here, the stool display unit 40 in this embodiment reacts to stool display response factors (proteins, etc.) with a predetermined concentration or higher to display a color reaction or the like. The stool display response factors are smaller than the predetermined concentration, and the reaction is not easy to occur. .

一般，在健全者的尿液中不含蛋白質，且即使不健全者，尿中的蛋白質低於10,000mg/L。因此，在本實施形態，根據使用pH指示藥的蛋白質誤差法，糞便顯示部50對150mg/L以上的蛋白質作反應為理想，對5,000mg/L以上的蛋白質作反應更為理想，對10,000mg/L以上的蛋白質作反應又更理想。例如，使用溴酚藍作為化學成分的條件下，糞便顯示部50對150mg/L以上的蛋白質作反應時，將糞便顯示部50中每1cm2 的pH指示藥的適用量設為16.3μg為理想，糞便顯示部50對5,000mg/L以上的蛋白質作反應時，將糞便顯示部50中每1cm2 的pH指示藥的適用量設為0.5μg為理想，糞便顯示部50對10,000mg/L以上的蛋白質作反應時，將糞便顯示部50中每1cm2 的pH指示藥的適用量設為0.25μg為理想。此外，藉由將pH指示藥的適用量設為17.0μg以下，而使糞便顯示部40對於吸收性物品的穿用者的安全性提高。Generally, there is no protein in the urine of a sound person, and even if the person is not sound, the protein in the urine is less than 10,000 mg/L. Therefore, in this embodiment, according to the protein error method using a pH indicator drug, the stool display unit 50 is ideal to respond to proteins of 150 mg/L or more, and it is more ideal to respond to proteins of 5,000 mg/L or more, and to 10,000 mg. Proteins above /L are more ideal for reaction. For example, when bromophenol blue is used as the chemical component, when the stool display unit 50 reacts to 150 mg/L or more of protein, it is ideal to set the applicable amount of pH indicator drug per 1 cm 2 of the stool display unit 50 to 16.3 μg When the stool display unit 50 reacts to a protein above 5,000 mg/L, it is ideal to set the applicable amount of pH indicator drug per 1 cm 2 of the stool display unit 50 to 0.5 μg, and the stool display unit 50 responds to 10,000 mg/L or more When reacting with the protein of, it is ideal to set the applicable amount of the pH indicator drug per 1 cm 2 in the stool display part 50 to 0.25 μg. In addition, by setting the applied amount of the pH indicator drug to 17.0 μg or less, the safety of the stool display section 40 for the wearer of the absorbent article is improved.

在本實施形態，如此藉由調整pH指示藥的塗布量，與糞便顯示部40對糞便可反應的範圍比較，可相對縮小對尿可反應的範圍。換言之，可使糞便顯示部40對糞便的反應、與糞便顯示部40對尿的反應不同。藉此，可使糞便顯示部40對尿不易作反應。In this embodiment, by adjusting the application amount of the pH indicator drug in this way, the range that the stool display unit 40 can respond to feces can relatively narrow the range that can respond to urine. In other words, the response of the stool display unit 40 to stool can be made different from the response of the stool display unit 40 to urine. Thereby, the stool display part 40 can be made difficult to react to urine.

又，糞便顯示部40並不限定以上述的蛋白質作為反應因子者。例如，亦可與糞便中所含的腸內細菌、與糞便的比重有相關關係的糞便的離子強度、膽汁色素的膽紅素等來自於糞便的物質作反應。該等的成分是一般不含於尿、或是與糞便比較尿所含有的量、比重非常小。因此，與以蛋白質作為反應因子時同樣，糞便顯示部40成為對尿不易反應，對糞便容易反應。因此，可精度佳地檢測出在紙尿布1被***出的糞便。In addition, the stool display unit 40 is not limited to those using the aforementioned protein as a response factor. For example, it may also react with stool-derived substances such as intestinal bacteria contained in stool, the ionic strength of stool related to the specific gravity of stool, and bilirubin of bile pigment. These ingredients are generally not contained in urine, or the amount and specific gravity contained in urine are very small compared with feces. Therefore, similarly to the case where protein is used as a response factor, the stool display part 40 becomes less responsive to urine and easily responsive to stool. Therefore, the feces excreted in the diaper 1 can be detected accurately.

＜糞便顯示部40的具體的構成＞ 糞便顯示部40，是藉由將含有上述這樣的化學成分(例如pH指示藥)的接著劑(例如熱熔接著劑HMA)塗布在紙尿布1的背面薄片23的肌膚側面而被形成。在本實施形態，是如圖1所示，在寬邊方向的中央藉由使用塗抹將熱熔接著劑(HMA)從***部5跨到後部7塗布在沿著長邊方向的帶狀(或是線狀)的區域而形成糞便顯示部40。根據這樣的塗抹塗布，可以均等的膜厚形成不均勻少的糞便顯示部40，可提高糞便檢測精度。又，可抑制製造成本。此外，關於尿顯示部50也可以同樣的方式形成。<Specific structure of stool display section 40> The stool display portion 40 is formed by applying an adhesive (for example, a hot melt adhesive HMA) containing the above-mentioned chemical components (for example, a pH indicator) on the skin side of the back sheet 23 of the diaper 1. In this embodiment, as shown in Fig. 1, the hot melt adhesive (HMA) is applied in the center of the width direction from the lower part of the crotch 5 to the rear part 7 in a strip (or It is a linear region) and forms the stool display section 40. According to such smearing, the stool display portion 40 with less unevenness can be formed with a uniform film thickness, and stool detection accuracy can be improved. In addition, manufacturing costs can be suppressed. In addition, the urine display unit 50 can also be formed in the same manner.

又，也可藉由將化學成分與油墨混合，印刷塗布在背面薄片23、芯包層薄片12而形成糞便顯示部40。又，也可藉由將浸透了化學成分的濾紙、不織布利用熱熔接著劑(HMA)、超音波熔接接合固定在背面薄片23、芯包層薄片12而形成糞便顯示部40。In addition, it is also possible to form the stool display portion 40 by mixing chemical components and ink, and printing and coating the back sheet 23 and the core-cladding sheet 12. In addition, the stool display section 40 may be formed by fixing filter paper or non-woven fabric impregnated with chemical components to the back sheet 23 and the core cladding sheet 12 by hot melt adhesive (HMA) or ultrasonic welding.

＜關於低基重部21A＞ 如上述，在本實施形態，雖是以在吸收體21的非肌膚側配置糞便顯示部40來檢測糞便，可是，通常因為糞便高黏性且流動性低，所以在厚度方向不易透過吸收體。因此，將糞便顯示部40設在吸收體21的非肌膚側時，會有糞便不易到達該糞便顯示部40的顧慮。＜About the low basis weight 21A＞ As described above, in the present embodiment, the stool display section 40 is arranged on the non-skin side of the absorber 21 to detect stool. However, since stool is generally highly viscous and has low fluidity, it does not easily penetrate the absorber in the thickness direction. Therefore, when the stool display section 40 is provided on the non-skin side of the absorber 21, there is a concern that stool may not easily reach the stool display section 40.

而相對於此，在本實施形態，吸收體21在寬邊方向的中央部具有低基重部21A(參照圖2)。在低基重部，基重形成的比從寬邊方向的外側和低基重部21A相鄰的區域21B、21B的基重更低。於此，基重是指每單位面積的質量。本實施形態的低基重部21A的基重在0～200g/m2 左右為理想，在100g/m2 左右更為理想。相鄰的區域21的各個的基重是370g/m2 左右為理想。此外，若低基重部21A的基重超過200g/m2 ，則基重太高，使得糞便透過低基重部21A的情況變困難。On the other hand, in this embodiment, the absorber 21 has a low basis weight 21A (refer to FIG. 2) in the center part of the width direction. In the low basis weight portion, the basis weight is formed to be lower than the basis weight of the regions 21B and 21B adjacent to the low basis weight portion 21A from the outside in the widthwise direction. Here, the basis weight refers to the mass per unit area. The present embodiment of the low basis weight portion 21A basis weight 0 ~ 200g / m 2 over about, more preferably about 100g / m 2. It is desirable that the basis weight of each adjacent region 21 is about 370 g/m 2 . In addition, if the basis weight of the low basis weight portion 21A exceeds 200 g/m 2 , the basis weight is too high, making it difficult for feces to penetrate the low basis weight portion 21A.

於此，前述的糞便顯示部40，是如圖2被設在吸收體21的厚度方向的非肌膚側。又，糞便顯示部40與低基重部21A如圖1所示，在長邊方向及寬邊方向具有重複的部分。如本實施形態，在厚度方向將糞便顯示部40配置在低基重部21A的非肌膚側(參照圖2)，而形成糞便的水分通過低基重部21A可順暢地透過吸收體21。藉此，使得來到糞便顯示部40的糞便的水分的到達提升，而可使糞便顯示部40有效地反應。Here, the aforementioned stool display portion 40 is provided on the non-skin side in the thickness direction of the absorber 21 as shown in FIG. 2. In addition, as shown in FIG. 1, the stool display section 40 and the low basis weight section 21A have overlapping portions in the longitudinal direction and the width direction. As in this embodiment, the stool display portion 40 is arranged on the non-skin side of the low basis weight portion 21A in the thickness direction (see FIG. 2), and the moisture forming stool can smoothly permeate the absorber 21 through the low basis weight portion 21A. Thereby, the arrival of the moisture of the feces that has reached the stool display portion 40 is increased, and the stool display portion 40 can be effectively reacted.

又，前述低基重部21A至少在一部分具有比從寬邊方向的外側和低基重部21A相鄰的區域21B、21B的密度更密度高的高密度部區域21A’為期望(參照圖3)。密度的測量方法，是算出對吸收體21所含的紙漿纖維及SAP等進行合計的基重(g/m2 )，來測量該部分的吸收體21的厚度(mm)。然後從上述基重與厚度的數值算出密度。本實施形態的低基重部21A’的密度理想是200～900kg/m3 ，更理想是333kg/m3 左右。區域21B、21B的密度理想是185kg/m3 左右。在低基重部21A設置高密度區域21A’，藉由其他的吸收體21的部分(區域21B、21B)與低基重部21A形成疏密構造，而形成容易將糞便的水分吸入密度高的低基重部21A側。因此，即使少量的糞便也可使糞便顯示部40有效地反應。In addition, it is desirable that the low basis weight portion 21A has at least a portion of the high density portion region 21A' that is denser than the regions 21B and 21B adjacent to the low basis weight portion 21A from the outside in the widthwise direction (see FIG. 3 ). The density measurement method is to calculate the total basis weight (g/m 2 ) of the pulp fiber, SAP, etc. contained in the absorber 21, and measure the thickness (mm) of the absorber 21 in this part. Then calculate the density from the above-mentioned basis weight and thickness. The density of the low basis weight portion 21A' of the present embodiment is desirably 200 to 900 kg/m 3 , and more desirably about 333 kg/m 3 . The density of the regions 21B and 21B is preferably about 185 kg/m 3 . A high-density area 21A' is provided in the low-basis-weight portion 21A, and the other parts of the absorbent body 21 (area 21B, 21B) and the low-basis-weight portion 21A form a dense and dense structure, thereby forming a dense structure that easily absorbs fecal moisture. The low basis weight 21A side. Therefore, even a small amount of stool can make the stool display section 40 effectively react.

再者，糞便顯示部40在厚度方向位在上述的高密度區域21A’的非肌膚側，且在長邊方向及寬邊方向配置成具有高密度區域21A’與重複的部分。如上述，藉由低基重部21A的高密度區域21A’與區域21B、21B所致的疏密構造在高密度區域21A’容易吸入糞便，再者，將糞便顯示部40配置成在厚度方向與高密度區域21A’對應，使得往糞便顯示部40的糞便的吸入性提升，可使糞便顯示部40更有效地反應。In addition, the stool display section 40 is located on the non-skin side of the above-mentioned high-density area 21A' in the thickness direction, and is arranged to have the high-density area 21A' and overlapping portions in the longitudinal direction and the width direction. As described above, the high density region 21A' and the regions 21B, 21B of the low basis weight portion 21A have a dense structure resulting in easy inhalation of stool in the high density region 21A'. Furthermore, the stool display portion 40 is arranged in the thickness direction Corresponding to the high-density area 21A', the inhalation of stool to the stool display section 40 is improved, and the stool display section 40 can be more effectively reacted.

接著，針對在低基重部21A具有基重為零的部分的情況進行說明。圖3表示低基重部21A(吸收性芯24)的其他的結構的部分放大剖視圖。如圖3所示，低基重部21A至少在寬邊方向的中央部也可具有基重為零的區域21C(以下也稱為「細縫21C」)。此時，高密度區域21A’在低基重部21A位在較細縫21C更靠寬邊方向的外側且沿著長邊方向被設成一對。不僅在低基重部21A設置高密度區域21A’而形成疏密構造，如圖3因為具有各高密度區域21A’朝向寬邊方向中央部慢慢減低基重的梯度，所以形成進一步朝向寬邊方向中央部容易吸入糞便的水分。再者，在低基重部21A的寬邊方向中央部設置基重為零的區域21C(細縫21C)，而形成藉由糞便的水分透過區域21C，而進一步被吸入到厚度方向的下層。藉由往下層的吸入性的提升，結果來說使糞便顯示部40的反應提升。此外，圖3的高密度區域21A’雖朝向寬邊方向中央基重變低地具有梯度，可是不是被這個所限定者。在各高密度區域21A’只要是比從寬邊方向的外側相鄰的區域21B、21B的基重更低的基重，則亦可具有預定的均一的基重、或使部分基重進行變化。Next, a case where the low basis weight portion 21A has a portion with a basis weight of zero will be described. Fig. 3 shows a partially enlarged cross-sectional view of another structure of the low basis weight portion 21A (absorbent core 24). As shown in FIG. 3, the low basis weight 21A may have a region 21C (hereinafter also referred to as "slit 21C") where the basis weight is zero at least in the center portion in the widthwise direction. At this time, the high-density regions 21A' are positioned on the outer side of the narrower slit 21C in the widthwise direction in the low basis weight portion 21A, and are provided as a pair along the lengthwise direction. Not only is the high-density region 21A' provided in the low-basis-weight portion 21A to form a dense structure, as shown in Figure 3, because each high-density region 21A' gradually decreases the gradient of the basis weight toward the center of the broadside direction, it is formed further toward the broadside The central part of the direction is easy to inhale the moisture of feces. Furthermore, a region 21C (slit 21C) with a basis weight of zero is provided in the center of the widthwise direction of the low basis weight portion 21A, and the fecal moisture permeable region 21C is formed to be further sucked into the lower layer in the thickness direction. As a result of the improvement of the inhalation to the lower layer, the response of the stool display section 40 is improved as a result. In addition, although the high-density region 21A' of FIG. 3 has a gradient such that the central basis weight decreases toward the widthwise direction, it is not limited by this. In each high-density region 21A', as long as the basis weight is lower than the basis weight of the regions 21B and 21B adjacent from the outside in the widthwise direction, it may have a predetermined uniform basis weight, or a partial basis weight may be changed. .

又，在本實施形態，上述的細縫21C與糞便顯示部40在長邊方向及寬邊方向具有重複的部分。藉此，糞便的水分可透過低基重部21A中基重為零的區域(細縫21C)，而可使吸收體21順暢地透過。又，如圖3所示，在吸收體21(吸收性芯24)的厚度方向的非肌膚側，相對於糞便顯示部40在寬邊方向外側分離設有一對的尿顯示部50。然後，作為吸收體21中低基重部21A以外的部分的非低基重部(21B)、與一對的尿顯示部50在長邊方向及寬邊方向具有重複的部分。使各尿顯示部50對應與低基重部21A不同的非低基重部進行配置，可防止各尿顯示部50因糞便而被汙染的情況。又，也可防止因糞便的油膜使尿顯示部50的反應降低的情況，而不會阻礙尿顯示部50對尿的反應。In addition, in this embodiment, the aforementioned slit 21C and the stool display portion 40 have overlapping portions in the longitudinal direction and the width direction. Thereby, the moisture of feces can permeate the area (slit 21C) in which the basis weight is zero in the low basis weight part 21A, and the absorber 21 can be permeated smoothly. In addition, as shown in FIG. 3, on the non-skin side in the thickness direction of the absorber 21 (absorbent core 24), a pair of urine display portions 50 are provided separately from the stool display portion 40 on the outside in the widthwise direction. Then, the non-low basis weight portion (21B), which is a portion other than the low basis weight portion 21A in the absorber 21, and the pair of urine display portions 50 have overlapping portions in the longitudinal direction and the width direction. By disposing each urine display part 50 corresponding to a non-low basis weight part different from the low basis weight part 21A, it is possible to prevent each urine display part 50 from being contaminated by feces. In addition, it is also possible to prevent a decrease in the response of the urine display unit 50 due to the oil film of feces, without hindering the response of the urine display unit 50 to urine.

又，在本實施形態，低基重部21A，是長邊方向中的低基重部21A的中心位在比表示紙尿褲1的長邊方向的中心的圖1的線B-B更靠後側為理想。紙尿布1的長邊方向的後方區域為穿用者的肛門對置的區域，在該區域設置低基重部21A，而可有效率地吸入糞便。In addition, in this embodiment, the low basis weight portion 21A is ideally located on the rear side of the line BB in FIG. 1 indicating the center of the long side direction of the low basis weight portion 21A in the longitudinal direction. . The rear area in the longitudinal direction of the paper diaper 1 is an area facing the anus of the wearer, and the low basis weight 21A is provided in this area, so that stool can be inhaled efficiently.

又，低基重部21A的長邊方向中的前側端為在比紙尿布1的長邊方向的中心(圖1的線B-B)更靠後側亦可。藉此，低基重部21A僅被配置在紙尿褲1的長邊方向的後側，在排便及排尿時，在糞便及尿容易流入的長邊方向的中心可保持高的吸收性。In addition, the front end in the longitudinal direction of the low basis weight portion 21A may be located on the rear side than the center of the paper diaper 1 in the longitudinal direction (line B-B in FIG. 1). Thereby, the low basis weight 21A is arranged only on the rear side in the longitudinal direction of the diaper 1, and during defecation and urination, high absorbency can be maintained at the center in the longitudinal direction where stool and urine easily flow in.

再者，低基重部21A在長邊方向，被配置在較作為紙尿布1的中心的圖1的線B-B更靠後側的面積比被配置在較線B-B更靠前側的面積更大為理想。亦即，在紙尿布1的長邊方向存在比後側更多的低基重部21A為理想。藉此，在對應穿用者的肛門位置的紙尿布1的後側區域，更多的糞便及糞便的水分可透過低基重部21A，而使糞便的吸入性提升。In addition, the low basis weight 21A has a larger area in the longitudinal direction than the line BB in FIG. 1 which is the center of the diaper 1 and is arranged in the front side of the line BB. As ideal. That is, it is desirable that there are more low basis weight portions 21A in the longitudinal direction of the diaper 1 than on the rear side. Thereby, in the rear area of the diaper 1 corresponding to the position of the wearer's anus, more feces and fecal moisture can penetrate the low basis weight portion 21A, thereby improving the inhalation of feces.

同樣，糞便顯示部40也在長邊方向，被配置在較作為紙尿布1的中心的圖1的線B-B更靠後側的面積比被配置在較線B-B更靠前側的面積更大為理想。糞便顯示部40在接近排便位置的紙尿布1的後側區域配置更多，所以，糞便顯示部40在寬廣範圍可有效地反應。Similarly, the stool display section 40 is also in the longitudinal direction, and the area arranged on the back side of the line BB of FIG. 1 as the center of the diaper 1 is larger than the area arranged on the front side of the line BB. ideal. Since the stool display part 40 is more arrange|positioned in the back side area of the diaper 1 which is close to a defecation position, the stool display part 40 can respond effectively in a wide range.

＜關於第二薄片35＞ 在本實施形態，第二薄片35在厚度方向被配置在較頂面薄片22更靠非肌膚側，且被配置成與吸收體21的芯包層薄片25接觸(參照圖2)。再者，第二薄片35與低基重部21A在長邊方向及寬邊方向具有重複的部分(參照圖1)。就第二薄片35的一例來說可舉嫘縈與紙漿的混棉纖維薄片。該薄片的基重(g/m2 )是35g/m2 左右為理想，而形成第1層為嫘縈100%，第2層為紙漿纖維100%，第3層為嫘縈100%的3層構造。第二薄片35由親水素材所構成為理想，藉由親水素材的效果使得與糞便中的水分的親和性提高，而更容易吸收糞便。在本實施形態的第二薄片35並不是嫘縈單體，而是藉由將紙漿纖維配置在嫘縈間，而使紙漿纖維填補嫘縈纖維彼此的間隙作為連繫纖維彼此的作用，提高密度可進一步容易吸入糞便中的水分。<Regarding the second sheet 35> In the present embodiment, the second sheet 35 is arranged on the non-skin side of the top sheet 22 in the thickness direction, and is arranged so as to be in contact with the core covering sheet 25 of the absorbent body 21 (see figure 2). Furthermore, the second sheet 35 and the low basis weight portion 21A have overlapping portions in the longitudinal direction and the width direction (see FIG. 1). As an example of the second sheet 35, a cotton fiber sheet of rayon and pulp can be cited. The basis weight (g/m 2 ) of the sheet is ideally about 35 g/m 2 , and the first layer is 100% rayon, the second layer is 100% pulp fiber, and the third layer is 100% rayon 3 Layer structure. The second sheet 35 is ideally composed of a hydrophilic material. The effect of the hydrophilic material increases the affinity with the moisture in the feces and makes it easier to absorb the feces. The second sheet 35 in this embodiment is not a single rayon, but by arranging pulp fibers between the rayon, the pulp fiber fills the gaps between the rayon fibers as a function of connecting fibers to improve the density. It is easier to inhale the moisture in the stool.

如此，因為第二薄片35的糞便的水分的拉起性高，所以可使粒子與水分混合的狀態的頂面薄片22上的糞便中，僅使水分從頂面薄片22滲透到第二薄片35。滲透到第二薄片35的糞便去除了粒子因為水分多，所以，藉由低基重部21A的高密度區域21A’的疏密構造，容易使糞便從第二薄片35滲透、透過到密度高的低基重部21A。就結果來說，使得往糞便顯示部40的糞便的到達提升。In this way, since the second sheet 35 has high pullability of moisture in the stool, it is possible to allow only the moisture to penetrate from the top sheet 22 to the second sheet 35 in the stool on the top sheet 22 in a state where the particles and moisture are mixed. . The stool that has penetrated into the second sheet 35 removes particles. Because there is a lot of water, the dense structure of the high-density area 21A' of the low basis weight portion 21A makes it easy for the stool to penetrate from the second sheet 35 and penetrate to the denser Low basis weight 21A. As a result, the arrival of feces to the feces display portion 40 is improved.

＜關於糞便顯示部40及尿顯示部50的一例＞ 本實施形態的糞便顯示部40及尿顯示部50並不是圖1所示這樣的帶狀的圖形，也可由各自不同的圖案的圖形所形成。圖4表示尿顯示部40及糞便顯示部50的圖案的一例的圖。糞便顯示部40在厚度方向位在低基重部21A、與被設在較吸收體21更靠厚度方向的非肌膚側的背面薄片23之間(參照圖2)，當與糞便接觸時進行視覺性的變化。例如，糞便顯示部40及尿顯示部50也可由圖4所示這樣的圖案所構成。在圖4，臉的印記為尿顯示部50，星型印記為糞便顯示部40。各糞便顯示部40及尿顯示部50具有相同或不同的預定的顏色，而構成在排尿後獲排便後呈現與當初的預定的顏色不同的其他的顏色。藉由與穿用者的糞便反應而使糞便顯示部40及尿顯示部50在視覺上進行變化，而可從紙尿布1的外面迅速且容易認出排便、排尿的有無，而可減低糞便或尿的漏出。又，關於糞便，可抑制長時間糞便附著於肌膚所致的肌膚問題。再者，為了從紙尿布外面分辨排便或排尿的區別，當排便時，紙尿布更換者伴隨著排便時的更換進行準備而可應付更換作業。<About an example of the stool display part 40 and the urine display part 50> The stool display section 40 and the urine display section 50 of the present embodiment are not belt-shaped patterns as shown in FIG. 1, and may be formed of patterns with different patterns. FIG. 4 is a diagram showing an example of patterns of the urine display section 40 and the stool display section 50. The stool display portion 40 is located between the low basis weight portion 21A in the thickness direction and the back sheet 23 provided on the non-skin side in the thickness direction than the absorber 21 (see FIG. 2), and visualizes when it comes into contact with stool Sexual changes. For example, the stool display section 40 and the urine display section 50 may also be composed of a pattern as shown in FIG. 4. In FIG. 4, the mark of the face is the urine display part 50 and the star mark is the stool display part 40. The stool display section 40 and the urine display section 50 have the same or different predetermined colors, and are configured to show a different color from the original predetermined color after urination is obtained. The stool display section 40 and the urine display section 50 are visually changed by reacting with the feces of the wearer, and the presence or absence of defecation and urination can be quickly and easily recognized from the outside of the diaper 1, thereby reducing stool or urination. Leaking of urine. In addition, with regard to feces, it is possible to suppress skin problems caused by long-term attachment of feces to skin. Furthermore, in order to distinguish the difference between defecation and urination from the outside of the paper diaper, when defecation, the paper diaper changer prepares for the change during defecation and can cope with the replacement work.

又，如圖1所示，糞便顯示部40長邊方向的長度比低基重部21A的長邊方向的長度更長為理想。將糞便顯示部40的長度設長，而容易各個角度確認排便後視覺變化後的糞便顯示部，可早期注意到排便。Moreover, as shown in FIG. 1, it is desirable that the length of the long side direction of the stool display part 40 is longer than the length of the long side direction of 21 A of low basis weight parts. By setting the length of the stool display portion 40 to be long, the stool display portion after the visual change after defecation can be easily recognized from various angles, and the stool can be noticed early.

然而，糞便顯示部40的長邊方向的長度沒有必要一定要設定的比低基重部21A的長邊方向的長度更長，在長邊方向及寬邊方向，也可將糞便顯示部40設在位於較低基重部21A的兩端部更靠內側。在長邊方向及寬邊方向的兩方向以包含在低基重部21A的方式配置糞便顯示部40，藉此使糞便的水分也容易到達糞便顯示部的任一部分。However, the length of the stool display portion 40 in the longitudinal direction does not necessarily have to be set to be longer than the length of the low basis weight portion 21A in the longitudinal direction. In the longitudinal direction and the width direction, the stool display portion 40 may be provided. The two ends of the lower base weight 21A are located more inside. The stool display section 40 is arranged in both the longitudinal direction and the width direction so as to be included in the low basis weight 21A, thereby making it easy for the moisture of the stool to reach any part of the stool display section.

在本實施形態，糞便顯示部40在厚度方向被配置在吸收體21的低基重部21A與背面薄片23之間。而且，於寬邊方向在與低基重部21A對應的區域，將頂面薄片22與第二薄片35、第二薄片35與芯包層薄片25、及芯包層薄片25與背面薄片23分別接合在厚度方向。In the present embodiment, the stool display portion 40 is arranged between the low basis weight portion 21A of the absorber 21 and the back sheet 23 in the thickness direction. In the widthwise direction, in the region corresponding to the low basis weight portion 21A, the top sheet 22 and the second sheet 35, the second sheet 35 and the core-cladding sheet 25, and the core-cladding sheet 25 and the back sheet 23 are respectively separated Join in the thickness direction.

又，如圖3所示，低基重部21A至少在寬邊方向的中央部具有細縫21C時，也可將頂面薄片22、第二薄片35、芯包層薄片25、及背面薄片23接合在厚度方向。此時，在芯包層薄片25，覆蓋吸收性芯24的肌膚側面的肌膚側部25a、以及覆蓋非肌膚側面的非肌膚側部25b於寬邊方向在與細縫21C對應的區域被接合在厚度方向為理想。In addition, as shown in FIG. 3, when the low basis weight portion 21A has a slit 21C at least in the center of the widthwise direction, the top sheet 22, the second sheet 35, the core clad sheet 25, and the back sheet 23 Join in the thickness direction. At this time, in the core cladding sheet 25, the skin side portion 25a covering the skin side of the absorbent core 24 and the non-skin side portion 25b covering the non-skin side surface are joined in the widthwise direction in the region corresponding to the slit 21C The thickness direction is ideal.

各薄片的接合方法可舉：將熱熔接著劑等用噴塗法、螺旋噴灑法、亞米茄噴灑法、幕式噴灑法等周知的塗布方法進行塗布加以固定的方法；超音波熔接(超音波密封)法等。The joining method of each sheet includes: a method of applying and fixing hot melt adhesive etc. by spraying method, spiral spraying method, Omega spraying method, curtain spraying method and other well-known coating methods; ultrasonic welding (ultrasonic Seal) method and so on.

如此，與低基重部21A或細縫C在寬邊方向對應的區域，將在厚度方向相鄰的上述各薄片分別接合，在各薄片間與厚度方向部會產生空間，可使得往厚度方向非肌膚側的糞便的水分的吸入性提升。In this way, in the region corresponding to the low basis weight portion 21A or the slit C in the width direction, each of the above-mentioned sheets adjacent in the thickness direction are respectively joined, and a space is created between the sheets and the thickness direction portion, which can make the thickness direction The moisture inhalation of feces on the non-skin side is improved.

又，各上述薄片間的低基重部21中的接合強度，是第二薄片35與芯包層薄片25的接合強度比頂面薄片22與第二薄片35的接合強度更高為理想。在糞便中，雖然通常粒徑大的粒子與水分混合在一起，可是，在其粒子與水分混著的狀態的糞便最不易透過的頂面薄片22，藉由降低熱熔接著劑等的接著劑的密度，而不易阻礙糞便透過頂面薄片22的情況。另一方面，在第二薄片35因為透過從頂面薄片22被過濾的糞便的水分，所以，即使提高接合第二薄片35與芯包層薄片25的熱熔接著劑等的接著劑的密度，也不會阻礙滲透。In addition, the bonding strength in the low basis weight portion 21 between the respective sheets is preferably that the bonding strength between the second sheet 35 and the core clad sheet 25 is higher than the bonding strength between the top sheet 22 and the second sheet 35. In feces, although particles with a large particle size are usually mixed with water, the top sheet 22, which is the least permeable feces in a state where the particles and water are mixed, is reduced by reducing adhesives such as hot melt adhesives. It is difficult to hinder the passage of feces through the top sheet 22. On the other hand, because the second sheet 35 penetrates the moisture of the feces filtered from the top sheet 22, even if the density of the adhesive such as the hot melt adhesive that joins the second sheet 35 and the core cladding sheet 25 is increased, It will not hinder penetration.

圖5表示紙尿布1的變形例的圖。在圖5中的吸收體21的***部5，在靠近寬邊方向的兩端部的後部7形成有一對的缺口部60、60，同樣在靠近寬邊方向的兩端部的前部3形成有一對的缺口部60、60。缺口部60不是二對亦可，也可為一對。一對的缺口部60，是吸收體21的寬邊方向的兩端部朝向寬邊方向內側形成山形形狀。此外，缺口部60的形狀不限於圖5所示的形狀。又，於本變形例，在各缺口部60雖將吸收體21(吸收性芯24)形成凹口，可是，也可藉由比吸收體21的其他的部分更減少液體吸收性素材的基重量而被形成。FIG. 5 shows a diagram of a modified example of the paper diaper 1. In the lower part 5 of the crotch of the absorber 21 in FIG. 5, a pair of notches 60, 60 are formed in the rear part 7 close to both ends in the width direction, and similarly formed in the front part 3 close to both ends in the width direction. There are a pair of notches 60 and 60. The notch 60 may not be two pairs, but may be a pair. The pair of notch portions 60 are formed in a chevron shape at both ends in the width direction of the absorber 21 toward the inner side in the width direction. In addition, the shape of the notch 60 is not limited to the shape shown in FIG. 5. In addition, in this modification, although the absorbent body 21 (absorbent core 24) is formed as a notch in each notch portion 60, the basis weight of the liquid-absorbent material may be reduced compared to other parts of the absorbent body 21. Is formed.

而且，在圖5所示的紙尿布1，在靠近後部7的一對的缺口部60、60於寬邊方向被夾著的吸收體21(吸收性芯24)的部位、與糞便顯示部40在長邊方向及寬邊方向具有重複的部分。藉由一對的各缺口部60抑制吸收性芯24的偏移、在紙尿布1與穿用者之間產生間隙的情況，而可抑制***物的洩漏。再者，因為被一對的缺口部60夾著的吸收性芯24的部位可牢牢地確保糞便，所以，在對應其被夾著的部位的位置配置糞便顯示部40，則往糞便顯示部40的糞便的到達也提升。Furthermore, in the paper diaper 1 shown in FIG. 5, the part of the absorbent body 21 (absorbent core 24) sandwiched in the widthwise direction between the pair of notch parts 60, 60 near the rear part 7 and the stool display part 40 There are overlapping parts in the long side direction and the wide side direction. The pair of each notch 60 suppresses the deviation of the absorbent core 24 and creates a gap between the paper diaper 1 and the wearer, thereby suppressing the leakage of excrement. Furthermore, because the part of the absorbent core 24 sandwiched by the pair of notches 60 can securely secure stool, the stool display part 40 is arranged at a position corresponding to the sandwiched part, and the stool display part The arrival of 40's feces is also improved.

＝＝＝其他的實施形態＝＝＝ 以上，雖針對本發明的實施形態進行說明，可是，上述的實施形態是為了容易本發明的理解者，而不是用來限定本發明進行解釋者。又，本發明只要不脫離其宗旨，得以變更、改良，且不用說本發明當然也含有其等價物。===Other embodiments === Although the embodiments of the present invention have been described above, the above-mentioned embodiments are intended to facilitate the understanding of the present invention, and are not intended to limit the explanation of the present invention. In addition, the present invention can be modified and improved as long as it does not deviate from its spirit, and it goes without saying that the present invention also includes equivalents.

於上述的實施形態，雖在厚度方向將第二薄片35配置在頂面薄片22與芯包層薄片25之間，可是，也可作為使液體擴散的擴散薄片配置在吸收體21與糞便顯示部40之間。這樣一來，可使透過低基重部21A的糞便的水分在吸收體21的下層擴散，可使糞便顯示部40在更寬廣的範圍反應。藉此，可提高來自紙尿布1外面的視認性。In the above-mentioned embodiment, although the second sheet 35 is arranged between the top sheet 22 and the core cladding sheet 25 in the thickness direction, it may be arranged on the absorber 21 and the stool display portion as a diffusion sheet for diffusing liquid. Between 40. In this way, the moisture of the stool that has passed through the low basis weight portion 21A can be diffused in the lower layer of the absorber 21, and the stool display portion 40 can be allowed to react in a wider range. Thereby, the visibility from the outside of the diaper 1 can be improved.

又，頂面薄片22具有開口亦可。藉由具有開口，增加第二薄片35與糞便接地面積，而可使往第二薄片35的糞便的透過性提升。In addition, the top sheet 22 may have openings. By having the opening, the grounding area between the second sheet 35 and the feces is increased, and the permeability of the feces to the second sheet 35 can be improved.

又於上述的實施形態，低基重部21A的形狀在圖1所示的俯視觀看雖為長邊方向長的長方形狀，可是形狀不限於此。例如，亦可為正方形、寬邊方向長的長方形狀、心型等的圖形形狀等。In the above-described embodiment, the shape of the low basis weight portion 21A is a rectangular shape with a long side in the plan view shown in FIG. 1, but the shape is not limited to this. For example, it may be a square shape, a rectangular shape long in the width direction, a heart shape, or other graphic shapes.

又於圖2及圖3所示的低基重部21A，在從寬邊方向的外側相鄰的區域21B、21B不限於基重為一定，例如也可形成在寬邊方向從兩端部朝向中央部使基重階段性的減低。In the low basis weight 21A shown in FIGS. 2 and 3, the regions 21B and 21B adjacent to the outside in the widthwise direction are not limited to a constant basis weight. For example, they may be formed in the widthwise direction from both ends toward The central part gradually reduces the basis weight.

又，上述的實施形態中的低基重部21A，其基重與在低基重部21A從寬邊方向的外側相鄰的區域21B、21B的基重比較雖變低，可是不限於此，例如也可為具有較吸收體的寬幅方向兩端的基重更低的基重的低基重部21A。In addition, the low basis weight portion 21A in the above-described embodiment has a basis weight lower than the basis weight of the regions 21B and 21B adjacent to the low basis weight portion 21A from the outside in the widthwise direction, but it is not limited to this. For example, it may be the low basis weight part 21A which has a basis weight lower than the basis weight of the both ends of the width direction of an absorber.

又於上述的實施形態，低基重部21A的數量雖在紙尿布1的寬邊方向的中央部為1個，可是，低基重部21A設置複數個亦可。此時，相對於各低基重部21A以在長邊方向及寬邊方向具有重複的部分的方式配置複數個糞便顯示部40，而可使排便的偵測更提升。In the above-described embodiment, the number of the low basis weight portion 21A is one in the center portion of the widthwise direction of the diaper 1, but the low basis weight portion 21A may be provided in plural. At this time, with respect to each low basis weight portion 21A, a plurality of stool display portions 40 are arranged to have overlapping portions in the longitudinal direction and the width direction, so that the detection of defecation can be improved.
