Description

吸收性物品Absorbent article

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

作為吸收***物之吸收性物品已知有用後即棄式紙尿褲。就這樣的用後即棄式紙尿褲的一形態來說，已知有在吸收***物的吸收性本體的非肌膚側面標示人物角色、花紋等的圖案，來提高設計性的紙尿褲。例如，在專利文獻1揭示有：構成紙尿褲的構件中，在形成背面薄片的不織布、及形成伸縮構件的絲線橡膠，藉由將氧化鈦的含有量設在5重量%以下，提高透過絲線橡膠、不織布之標示在背面薄片的內側的圖案的視認性之用後即棄式紙尿褲。 [先前技術文獻] [專利文獻]A disposable diaper is known as an absorbent article that absorbs excrement. In one aspect of the disposable diaper, it is known that a pattern of a person character, a pattern, or the like is marked on the non-skin side of the absorbent main body that absorbs excrement, and the design diaper is improved. For example, in the member constituting the diaper, the nonwoven fabric forming the back sheet and the thread rubber forming the stretchable member are provided with the content of the titanium oxide being 5% by weight or less, thereby improving the transmission of the threaded rubber. A disposable diaper is used after the visibility of the pattern of the inside of the back sheet is indicated by the non-woven fabric. [Prior Technical Literature] [Patent Literature]

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

可是，專利文獻1的用後即棄式紙尿褲，因為材料的成分(氧化鈦的含有量)有所限制，所以會有不織布的白色度看起來低、或不織布本身看起來薄的情況。這樣的紙尿褲，會有讓使用者(讓穿用對象者穿用紙尿褲者，例如嬰幼兒的照護者)抱持使用中不織布是不是會撕破、或破損的不安的顧慮。尤其，在吸收性本體的前側接合前側帶構件，在吸收性本體的後側接合後側帶構件的所謂的3構件式的用後即棄式紙尿布，覆蓋穿用者的腰圍的帶構件若看起來薄，對於強度的不安變大，而會有不能安心使用紙尿布的顧慮。However, in the disposable diaper of Patent Document 1, since the composition of the material (the content of titanium oxide) is limited, the whiteness of the non-woven fabric may appear to be low, or the non-woven fabric itself may be thin. In such a diaper, there is a concern that the user (who wears a diaper, such as a caregiver of an infant) to hold the non-woven fabric in use, whether it is torn or broken. In particular, a front side belt member is joined to the front side of the absorbent body, a so-called three-piece disposable disposable diaper for joining the rear side belt member to the rear side of the absorbent body, and a belt member covering the wearer's waist circumference. It seems to be thin, and the uneasiness of strength becomes large, and there is a concern that the disposable diaper cannot be used with peace of mind.

本發明，是有鑑於上述這樣的問題所研發者，其目的之處，是在具有圖形的吸收性物品，不易讓使用者對帶構件的強度產生不安。 [解決課題用的手段]The present invention has been made in view of the above problems, and an object thereof is that it is difficult for the user to feel uncomfortable with the strength of the belt member in the absorbent article having a pattern.

關於本發明的其他的特徵，是由本說明書及添附圖面的記載可明白。 [發明的效果]Other features of the present invention will become apparent from the description of the specification and appended drawings. [Effects of the Invention]

根據本發明，在具有圖形的吸收性物品，不易讓使用者對帶構件的強度產生不安。According to the present invention, in the case of the absorbent article having a pattern, it is difficult for the user to feel uncomfortable with the strength of the belt member.

根據本說明書及添附圖面的記載，至少明白以下的事項。At least the following matters will be understood from the description of the specification and the accompanying drawings.

一種吸收性物品，係具有互相交叉的上下方向與左右方向及前後方向，吸收性本體，其是沿著前述上下方向被設置，在***部朝前後被折疊；前側帶構件，其是沿著前述左右方向被設置，在前側被接合在前述吸收性本體的前述上下方向的前側上端部；以及後側帶構件，其是與前述前側帶構件作成不同體，並沿著前述左右方向被設置，而在後側被接合在前述吸收性本體的前述上下方向的後側上端部，在前述左右方向，將前述前側帶構件的兩端部與前述後側帶構件的兩端部互相接合之吸收性物品，其特徵為：前述吸收性本體具備：液吸收性的吸收性芯、以及比前述吸收性芯更被配置在非肌膚側的液不透過性的防漏薄片，在前側及後側的至少一方側，在前述防漏薄片的非肌膚側面設有主要圖形，前述吸收性本體朝前述上下方向及前述左右方向被伸長的狀態，前述主要圖形的面積，是前述一方側的前述非肌膚側面的面積的40%以上，且，前述一方側的帶構件與前述主要圖形重複的部分的面積，是前述主要圖形的面積的50%以上。An absorbent article having an up-and-down direction and a left-right direction and a front-rear direction intersecting each other, an absorbent body disposed along the up-and-down direction and folded forward and backward in a crotch portion; a front side belt member along the aforementioned The left side direction is provided, the front side is joined to the front upper end portion of the absorbent body in the up-and-down direction; and the rear side belt member is formed differently from the front side belt member and is disposed along the left-right direction. The rear side is joined to the rear upper end portion of the absorbent body in the vertical direction, and the absorbent article of the both end portions of the front side belt member and the both end portions of the rear side belt member are joined to each other in the left-right direction. The absorptive body includes a liquid-absorbent absorbent core and a liquid-impermeable leakage preventing sheet disposed on the non-skin side than the absorbent core, and at least one of the front side and the rear side. a side surface having a main pattern on a non-skin side surface of the leakage preventing sheet, wherein the absorbent body is elongated in the vertical direction and the horizontal direction The area of the main pattern is 40% or more of the area of the non-skin side surface on the one side, and the area of the portion of the belt member that overlaps with the main pattern is 50% of the area of the main pattern. the above.

根據這樣的吸收性物品，在主要圖形與帶構件重複的區域，主要圖形的視認性下降，而使顏色看起來淡、或輪廓看起來模糊。藉此，使用者容易認識帶構件的厚度(厚度)，而可抑制使用者對帶構件的強度感到不安的情況。According to such an absorbent article, in a region where the main pattern and the belt member are repeated, the visibility of the main pattern is lowered, and the color is made pale or the outline is blurred. Thereby, the user can easily recognize the thickness (thickness) of the belt member, and it is possible to suppress the user from feeling uncomfortable with the strength of the belt member.

在這樣的吸收性物品，前述主要圖形，是跨前述吸收性本體與前述一方側的帶構件重複的區域、以及前述吸收性本體與前述一方側的帶構件沒有重複的區域的邊界被配置為期望。In such an absorbent article, the main pattern is such that a region overlapping the absorbent member and the one-side belt member and a region where the absorbent body and the one-side belt member are not overlapped are disposed in a desired state. .

根據這樣的吸收性物品，在沒有與帶構件重複的區域，主要圖形看起來鮮明，而相對於此，在與帶構件重複的區域，主要圖形的視認性看起來下降。因此，在主要圖形中與帶構件重複的部分、和沒有重複的部分視認性的差明確，可更容易認識帶構件的厚度。藉此，容易抑制使用者的不安。According to such an absorbent article, the main figure looks sharp in a region where there is no overlap with the belt member, whereas the visibility of the main pattern seems to decrease in a region overlapping the belt member. Therefore, the difference in the visibility of the portion overlapping with the belt member and the portion having no repetition in the main pattern is clear, and the thickness of the belt member can be more easily recognized. Thereby, it is easy to suppress the uneasiness of the user.

在這樣的吸收性物品，前述前側帶構件及前述後側帶構件分別具有肌膚側不織布與非肌膚側不織布，前述肌膚側不織布與前述非肌膚側不織布，是經由帶構件接合部在厚度方向重疊被接合，前述主要圖形的至少一部分與設有前述帶構件接合部的區域沒有重複為期望。In the absorbent article, the front side belt member and the rear side belt member each have a skin side non-woven fabric and a non-skin side non-woven fabric, and the skin side non-woven fabric and the non-skin side non-woven fabric are overlapped in the thickness direction via the belt member joint portion. Engaging, it is not necessary to repeat at least a part of the above-mentioned main pattern and a region in which the above-mentioned belt member joint portion is provided.

根據這樣的吸收性物品，在吸收性物品的穿用時，帶構件朝左右方向收縮時，在沒有設置帶構件接合部的區域會有肌膚側不織布與非肌膚側不織布朝厚度方向浮起的情況。如此藉由不織布浮起的部分與主要圖形重複被配置(亦即，主要圖形具有沒有與帶構件接合部重複的部分)，因此進一步降低該主要圖形的視認性，所以讓使用者更容易認識帶構件的厚度。According to such an absorbent article, when the tape member is shrunk in the left-right direction when the absorbent article is worn, the skin-side non-woven fabric and the non-skin-side non-woven fabric are floated in the thickness direction in a region where the tape member joint portion is not provided. . The portion that is floated by the non-woven fabric is repeatedly arranged with the main pattern (that is, the main pattern has a portion that is not overlapped with the belt member joint portion), thereby further reducing the visibility of the main pattern, so that the user can more easily recognize the belt. The thickness of the component.

在這樣的吸收性物品，前述吸收性本體在前述防漏薄片的非肌膚側具有外裝薄片，形成前述前側帶構件及前述後側帶構件的不織布的基重比形成前述外裝薄片的不織布的基重更大為期望。In such an absorbent article, the absorbent body has an exterior sheet on the non-skin side of the leakage preventing sheet, and the basis weight of the nonwoven fabric forming the front side belt member and the rear side belt member is smaller than the nonwoven fabric forming the exterior sheet. The basis weight is greater than expected.

根據這樣的吸收性物品，外裝薄片的不織布因為縮小基重，所以光透過性高，因為帶構件的不織布的基重大，所以光透過性變低。藉此，在吸收性本體與帶構件不重複的區域，主要圖形容易穿透看見，在吸收性本體與帶構件重複的區域主要圖形不易看見。因此，可讓使用者更容易認識帶構件的厚度。According to such an absorbent article, since the nonwoven fabric of the exterior sheet has a reduced basis weight, the light transmittance is high, and since the base of the nonwoven fabric of the belt member is large, the light transmittance is lowered. Thereby, in a region where the absorptive body and the belt member are not overlapped, the main pattern is easily penetrated and seen, and the main pattern is hard to see in the region where the absorptive body and the belt member are repeated. Therefore, it is easier for the user to recognize the thickness of the belt member.

在這樣的吸收性物品，前述前側帶構件及前述後側帶構件分別具有在前述左右方向伸縮的腰圍彈性構件，前述主要圖形的至少一部分，是與前述腰圍彈性構件所致的張力作用的區域重複為期望。In the absorbent article, the front side belt member and the rear side belt member each have a waist elastic member that expands and contracts in the left-right direction, and at least a part of the main pattern is overlapped with a region of tension caused by the waist elastic member. For the expectation.

根據這樣的吸收性物品，在吸收性物品的穿用時，藉由腰圍彈性構件的伸縮在帶構件的表面變形成形成有複數個皺紋的蛇腹狀。因此，在與形成有皺紋的區域重複的部分，主要圖形的視認性降低，而可讓使用者容易認識帶構件的厚度、柔軟度。According to such an absorbent article, when the absorbent article is worn, a bellows shape in which a plurality of wrinkles are formed is formed on the surface of the belt member by the expansion and contraction of the waist elastic member. Therefore, in the portion overlapping with the wrinkle-forming region, the visibility of the main pattern is lowered, and the thickness and softness of the tape member can be easily recognized by the user.

在這樣的吸收性物品，前述前側帶構件及前述後側帶構件，是經由沿著前述上下方向的複數個帶狀接合部在前述左右方向以預定的間隔被配置的本體接合部分別與前述吸收性本體接合，前述主要圖形的至少一部分與設有前述本體接合部的區域重複為期望。In the absorbent article, the front side belt member and the rear side belt member are respectively absorbed by the body joint portion which is disposed at a predetermined interval in the left-right direction via a plurality of belt-shaped joint portions along the vertical direction. The physical body is joined, and at least a portion of the aforementioned main pattern is repeated as desired with the region in which the body joint portion is provided.

根據這樣的吸收性物品，在吸收性物品的穿用時，在左右方向相鄰的2個帶狀接合部之間，帶構件與吸收性本體互相剝離地容易朝厚度方向浮起。在該浮起的區域，因為主要圖形的視認性大幅下降，所以，更容易認識帶構件的厚度、柔軟度。According to such an absorbent article, when the absorbent article is worn, the belt member and the absorbent body are easily peeled off from each other in the thickness direction between the two belt-shaped joint portions adjacent in the left-right direction. In the floating area, since the visibility of the main pattern is largely lowered, it is easier to recognize the thickness and softness of the belt member.

在這樣的吸收性物品，在前述吸收性本體的後側設有後側主要圖形為期望。In such an absorbent article, it is desirable to provide a rear main pattern on the rear side of the absorbent body.

根據這樣的吸收性物品，穿用者(嬰幼兒等)穿用吸收性物品的狀態下進行爬行時，在覆蓋嬰幼兒的臀部的吸收性本體的後側面，使用者(照護者等)的眼睛容易注意到後側主要圖形。因此，也容易認識在該後側主要圖形中與後側帶構件重複的部分、和不重複的部分視認性的差產生的情況。According to such an absorbent article, when the wearer (infant or the like) wears the absorbent article, the eye of the user (the caregiver or the like) is placed on the rear side of the absorbent body covering the buttocks of the infant. It is easy to notice the main graphics on the back side. Therefore, it is also easy to recognize that a difference between a portion overlapping with the rear side belt member in the rear main pattern and a portion of the non-repeating portion visibility is generated.

在這樣的吸收性物品，在前述吸收性本體的前側設有前側主要圖形，在前述吸收性本體的後側設有後側主要圖形，在前述上下方向，前述前側主要圖形的中央位置比前述後側主要圖形的中央位置更高為期望。In such an absorbent article, a front main pattern is provided on the front side of the absorbent body, and a rear main pattern is provided on the rear side of the absorbent body, and the center position of the front main pattern is higher than the rear in the vertical direction. The central position of the main graphic on the side is higher as desired.

根據這樣的吸收性物品，藉由在高的位置設置前側主要圖形，在穿用時，容易抑制前側主要圖形被穿用者的兩腿夾著而收縮的情況。另一方面，藉由在低的位置設置後側主要圖形，在穿用者的臀部的廣大的範圍容易視認後側主要圖形。因此，容易在各個最適合的狀態下視認前後的主要圖形。According to such an absorbent article, by providing the front main pattern at a high position, it is easy to suppress the front main pattern being contracted by the wearer's legs and contracting when worn. On the other hand, by providing the rear main pattern at a low position, it is easy to visualize the rear main pattern in a wide range of the wearer's buttocks. Therefore, it is easy to visualize the main graphics before and after in each of the most suitable states.

在這樣的吸收性物品，前述前側主要圖形的面積比前述後側主要圖形的面積更小為期望。In such an absorbent article, it is desirable that the area of the front side main pattern is smaller than the area of the rear side main pattern.

根據這樣的吸收性物品，藉由將後側主要圖形盡量形成的大，邊提高作為後側主要圖形整體的視認性，邊讓使用者容易認識在與後側帶構件重複的部分和不重複的部分，在視認性產生差的情況。According to such an absorbent article, by making the rear main pattern as large as possible, the visibility of the entire rear main pattern is improved, and the user can easily recognize the portion overlapping with the rear side member and the non-repeating In part, the situation is poor in visibility.

在這樣的吸收性物品，前述前側主要圖形與前述前側帶構件重複的部分的面積比前述後側主要圖形與前述後側帶構件重複的部分的面積更小為期望。In such an absorbent article, the area of the portion where the front side main pattern overlaps with the front side belt member is smaller than the area of the portion where the rear side main pattern and the rear side belt member overlap.

根據這樣的吸收性物品，由於後側主要圖形，是穿用者進行爬行時容易引起使用者的眼睛的注意，所以，藉由盡可能加大與後側帶構件的重複部分，該重複部分中的後側主要圖形的視認性的降低程度容易變的顯眼。因此，使用者容易認識帶構件的厚度。According to such an absorbent article, since the rear main pattern is likely to attract the attention of the user's eyes when the wearer is crawling, by repeating the overlap with the rear side belt member as much as possible, the repeating portion is The degree of reduction in the visibility of the main pattern on the back side is likely to become conspicuous. Therefore, the thickness of the belt member is easily recognized by the user.

在這樣的吸收性物品，前述主要圖形與前述吸收性本體的前述一方側的面重複的部分中的前述主要圖形的印刷色調值的平均、和前述主要圖形與前述吸收性本體的前述一方側的面不重複的部分中的前述主要圖形的前述印刷色調值的平均相等為期望。In the absorbent article, the average of the printing tone values of the main pattern in the portion where the main pattern overlaps with the one surface of the absorbent body, and the main pattern and the one side of the absorbent body The average of the aforementioned printing tone values of the aforementioned main patterns in the non-repeating portion is equal.

根據這樣的吸收性物品，被印刷的主要圖形的濃度在與帶構件重複的部分和不重複的部分成為同程度。從外側觀看這樣的吸收性物品時，在與帶構件重複的部分，主要圖形濃度比實際被印刷的圖像看起來淡。另一方面，在沒有與帶構件重複的部分，主要圖形與實際被印刷的圖像看起來同等的濃度。因此，在與帶構件重複的部分，主要圖形的視認性降低的情況變的明確，使用者容易認識帶構件的厚度。According to such an absorbent article, the concentration of the main pattern to be printed is the same as the portion overlapping with the belt member and the portion not overlapping. When such an absorbent article is viewed from the outside, the main pattern density is lighter than the actually printed image in the portion overlapping the belt member. On the other hand, in the portion where there is no overlap with the belt member, the main pattern looks like the same concentration as the actually printed image. Therefore, in the portion overlapping with the belt member, the visibility of the main pattern is lowered, and the thickness of the belt member is easily recognized by the user.

在這樣的吸收性物品，形成前述主要圖形的外形的輪廓線的粗細在3mm以上為期望。In such an absorbent article, it is desirable that the thickness of the outline of the outer shape of the main pattern is 3 mm or more.

根據這樣的吸收性物品，在主要圖形之上層積有複數個不織布的區域(與帶構件重複的區域)，透過該等的不織布邊可認識主要圖形的形狀，邊容易知道視認性降低的情況。According to such an absorbent article, a plurality of non-woven fabric regions (regions overlapping with the tape members) are stacked on the main pattern, and the shape of the main pattern can be recognized by the non-woven fabric edges, and it is easy to know that the visibility is lowered.

在這樣的吸收性物品，前述主要圖形，是與前述吸收性物品的製品包裝袋所表示的人物角色相同圖案為期望。In such an absorbent article, the main pattern is a pattern similar to the persona represented by the product packaging bag of the absorbent article.

根據這樣的吸收性物品，嬰幼兒、其照護者容易認識主要圖形，又，容易理解吸收性物品與主要圖形的關連性。According to such an absorbent article, the infant and the caregiver can easily recognize the main figure, and it is easy to understand the correlation between the absorbent article and the main figure.

在這樣的吸收性物品，在前述上下方向，前述吸收性本體的後側上端的位置比前述吸收性本體的前側上端的位置更高為期望。In such an absorbent article, the position of the upper end of the rear side of the absorbent body is higher than the position of the upper end of the front side of the absorbent body in the vertical direction.

根據這樣的吸收性物品，因為吸收性本體的後側面的面積比前側面的面積更大，在後側面使可印刷主要圖形的區域變大。因此，可更自由地設計後側主要圖形。藉此，可調高吸收性物品的設計性。According to such an absorbent article, since the area of the rear side surface of the absorbent body is larger than the area of the front side surface, the area where the main pattern can be printed is made larger on the rear side. Therefore, the rear main pattern can be designed more freely. Thereby, the design of the highly absorbent article can be adjusted.

在這樣的吸收性物品，在前述吸收性本體，沿著前述上下方向設有因與水分接觸使顏色進行變化的指示部，在前述上下方向，配置在前述吸收性本體的前側的前述指示部的長度比被配置在前述吸收性本體的後側的前述指示部的長度更長為理想。In the absorbent article, the indicator body is provided with an instruction portion that changes color in contact with the water in the vertical direction along the vertical direction, and is disposed on the front side of the absorbent body in the vertical direction. The length is preferably longer than the length of the aforementioned indication portion disposed on the rear side of the absorbent body.

根據這樣的吸收性物品，因為後側主要圖形與指示部不易重複，所以，可抑制後側主要圖形的視認性因指示部造成不必要的惡化情況。According to such an absorbent article, since the rear main pattern and the indication portion are not easily overlapped, it is possible to suppress unnecessary deterioration of the visibility of the rear main pattern due to the instruction portion.

在這樣的吸收性物品，在前述吸收性本體的前側設有前側主要圖形，在前述吸收性本體的後側設有後側主要圖形，前述前側主要圖形與前述指示部重複的部分的面積比前述後側主要圖形與前述指示部重複的部分的面積更大為期望。In such an absorbent article, a front main pattern is provided on a front side of the absorbent body, and a rear main pattern is provided on a rear side of the absorbent body, and an area of a portion of the front main pattern overlapping the indicator portion is larger than the aforementioned It is desirable that the area of the rear main pattern and the portion where the above-mentioned indication portion overlap is larger.

根據這樣的吸收性物品，因為後側主要圖形與指示部重複部分的面積小，所以，即使指示部的顏色變化的時候，後側主要圖形的視認性不易惡化。另一方面，前側主要圖形與指示部的重複部分的面積雖變大，可是，因為前側主要圖形與後側主要圖形比較不易被視認，所以，吸收性物品整體來說，視認性的惡化不易變顯眼。因此，使用者容易認識與帶構件重複的區域和不重複的區域中的主要圖形的視認性的差。According to such an absorbent article, since the area of the rear main pattern and the overlapping portion of the indicator portion is small, the visibility of the rear main pattern is less likely to deteriorate even when the color of the indicator portion changes. On the other hand, although the area of the front main pattern and the overlapping portion of the indicator portion is increased, the front main pattern and the rear main pattern are less likely to be viewed, so that the deterioration of visibility is not easily changed as a whole for the absorbent article. Conspicuous. Therefore, it is easy for the user to recognize the difference in visibility of the main pattern in the area overlapping with the belt member and the area in the non-overlapping area.

在這樣的吸收性物品，在前述吸收性本體的後側沒有配置前述指示部為期望。In such an absorbent article, it is desirable that the indicator portion is not disposed on the rear side of the absorbent body.

根據這樣的吸收性物品，因為可將指示部與後側主要圖形重複部分的面積作成最小，所以，即使指示部的顏色變化的時候，容易抑制後側主要圖形的不要的視認性的惡化。According to such an absorbent article, since the area of the indication portion and the rear main pattern overlapping portion can be minimized, even when the color of the indication portion changes, it is easy to suppress deterioration of unnecessary visibility of the rear main pattern.

在這樣的吸收性物品，前述後側主要圖形與前述指示部沒有重複為期望。In such an absorbent article, it is desirable that the rear main pattern and the indicator portion are not overlapped.

根據這樣的吸收性物品，即使指示部的顏色變化的時候，因為在後側主要圖形的視認性不易產生影響，所以，進一步容易抑制後側主要圖形的不要的視認性的惡化。According to such an absorbent article, even when the color of the indicator portion is changed, the visibility of the main pattern on the rear side is less likely to be affected, so that it is easier to suppress the deterioration of the visibility of the rear main pattern.

該紙尿褲1在圖1的褲型狀態具有上下方向與左右方向及前後方向作為互相正交的三方向。而且，在以下也將該褲型狀態中的上下方向的上側稱為「腰圍開口側」，也將上下方向的下側稱為「***側」。又，也將前後方向的前側稱為「腹側」，也將後側稱為「背側」。In the pants-type state of FIG. 1, the diaper 1 has three directions orthogonal to each other in the up-down direction, the left-right direction, and the front-back direction. In the following, the upper side in the up-and-down direction in the pants-type state is also referred to as the "waist opening side", and the lower side in the up-and-down direction is also referred to as the "underarm side". Further, the front side in the front-rear direction is also referred to as "ventral side", and the rear side is also referred to as "back side".

另一方面，在圖2的展開狀態，紙尿褲1具有長邊方向與寬邊方向作為互相正交的三方向。而且，在以下也將該展開狀態中的長邊方向的一方側及另一方側分別稱為「腹側」及「背側」。此外，展開狀態中的上述的寬邊方向，是與褲型狀態中的上述的左右方向同樣的方向。因此，在以下也將寬邊方向稱為「左右方向」。又，展開狀態的長邊方向，是沿著褲型狀態的上下方向的方向。又，如圖3所示，將與上下方向(長邊方向)及左右方向(寬邊方向)正交的方向作為「厚度方向」，將與穿用對象者的肌膚抵接之側作為「肌膚側」，將其相反側作為「非肌膚側」。On the other hand, in the unfolded state of Fig. 2, the diaper 1 has a longitudinal direction and a broad side direction as three directions orthogonal to each other. In addition, one side and the other side in the longitudinal direction in the developed state are also referred to as "ventral side" and "back side", respectively. Further, the above-described wide side direction in the unfolded state is the same direction as the above-described left and right direction in the pant type state. Therefore, the broad side direction is also referred to as "left and right direction" below. Further, the longitudinal direction of the unfolded state is the direction along the vertical direction of the pants-type state. In addition, as shown in FIG. 3, the direction orthogonal to the vertical direction (longitudinal direction) and the left-right direction (wide side direction) is referred to as "thickness direction", and the side that is in contact with the skin of the wearer is referred to as "skin Side", the opposite side is referred to as "non-skin side".

如圖1所示，紙尿褲1是所謂3構件式，並具有3個零件10、30、40。亦即，該紙尿褲1，是具有抵接在穿用者的胯間部吸收殘留的尿等的***物的吸收性本體10作為第1零件，具有從該穿用者的前側覆蓋腹側部的前側帶構件30作為第2零件，具有從該穿用者的後側覆蓋背側部的後側帶構件40作為第3零件。As shown in Fig. 1, the diaper 1 is a so-called three-member type and has three parts 10, 30, and 40. In other words, the diaper 1 is an absorbent main body 10 having an excrement such as urine that is absorbed by the wearer's crotch portion as a first component, and has a front side covering the ventral portion from the front side of the wearer. The front side belt member 30 is a second component, and has a rear side belt member 40 that covers the back side portion from the rear side of the wearer as a third component.

如圖2所示，在紙尿褲1的展開狀態，前側帶構件30與後側帶構件40互相在吸收性本體10的長邊方向(上下方向)分開間隔平行排列的狀態下，將吸收性本體10鋪設在該等之間。而且，包含吸收性本體10的前側上端10ea的前側上端部與前側帶構件30接合，包含吸收性本體10的後側上端10eb的後側上端部與後側帶構件40被接合固定，使其外觀形狀形成俯視觀看大致H形狀。As shown in Fig. 2, in the unfolded state of the diaper 1, the front side belt member 30 and the rear side belt member 40 are arranged in parallel with each other in the longitudinal direction (up-and-down direction) of the absorbent body 10, and the absorbent body 10 is placed in parallel. Laid between these. Further, the front upper end portion including the front upper end 10ea of the absorbent body 10 is joined to the front side belt member 30, and the rear side upper end portion including the rear side upper end 10eb of the absorbent body 10 is joined and fixed to the rear side belt member 40 to have an appearance thereof. The shape is formed to look at a substantially H shape in plan view.

而且，從該狀態，在長邊方向的折疊位置C10對折吸收性本體10。亦即，在***部朝前後被折疊。在該對折的狀態，互相對置的前側帶構件30與後側帶構件40，若在必須抵接在穿用者的側腹的部分的側緣接合部30ew、與側緣接合部40ew(亦即、左右方向的兩端部)被接合・連結，該等帶構件30、40彼此能成形成環狀。藉此，成為形成有圖1所示這樣的腰圍開口1HB及一對的腿圍開口1HL的穿用狀態的紙尿褲1。Further, from this state, the absorbent body 10 is folded in half at the folding position C10 in the longitudinal direction. That is, it is folded back and forth in the lower part of the crotch. In the folded state, the front side belt member 30 and the rear side belt member 40 which are opposed to each other are joined to the side edge joint portion 30ew and the side edge joint portion 40ew of the portion of the wearer's flank. In other words, both end portions in the left-right direction are joined and connected, and the belt members 30 and 40 can be formed in a ring shape. Thereby, the diaper 1 in which the waist opening 1HB and the pair of leg-openings 1HL shown in FIG. 1 are formed is formed.

(吸收性本體10) 　　吸收性本體10具有吸收尿等的***物的功能，如圖2及圖4所示形成俯視觀看大致長方形，邊讓其長邊方向沿著紙尿褲1的上下方向邊配置在左右方向的中央。吸收性本體10具備：吸收性芯11、從肌膚側包住吸收性芯11地加以覆蓋的表面薄片構件13、以及從非肌膚側覆蓋吸收性芯11，而形成吸收性本體10的外裝的裏面薄片部材15。(Absorbing body 10) The absorbent body 10 has a function of absorbing excrement such as urine, and is formed in a rectangular shape in plan view as shown in Figs. 2 and 4, and is disposed along the longitudinal direction of the diaper 1 in the longitudinal direction. The center in the left and right direction. The absorbent main body 10 includes an absorbent core 11 , a surface sheet member 13 that covers the absorbent core 11 from the skin side, and an absorbent core 11 that covers the non-skin side to form an exterior of the absorbent body 10 . Inside sheet member 15.

吸收性芯11，層積液吸收性素材而成的構件，可吸收尿等的***物。就液體吸收性素材來說，例如可使用紙漿纖維等的液體吸收性纖維。此外，吸收性芯11，以液體吸收性粒狀物來說也可例如含有高吸收性聚合物，或是也可包含液體吸收性纖維及液體吸收性粒狀物以外的液體吸收性素材。又，吸收性芯11也可用薄紙等的液體透過性薄片(不圖示)被覆。The absorbent core 11 is a member obtained by laminating a liquid absorbing material, and can absorb excrement such as urine. As the liquid absorbing material, for example, a liquid absorbing fiber such as pulp fiber can be used. Further, the absorbent core 11 may contain, for example, a highly absorbent polymer as the liquid absorbing granular material, or may contain a liquid absorbing material other than the liquid absorbing fibrous material and the liquid absorbing granular material. Further, the absorbent core 11 can also be coated with a liquid permeable sheet (not shown) such as tissue paper.

本實施形態的吸收性芯11具有圖2及圖4中作為上下方向的上側端部的前側端部11a、與圖3中作為上下方向的下側端部的後側端部11b。而且，在前側端部11a與後側端部11b之間，具有左右方向的寬度比前側端部11a及後側端部11b更窄的縮窄部11c。藉此，吸收性芯11是構成為圖2及圖4所示這樣的俯視觀看大致砂漏形狀。The absorbent core 11 of the present embodiment has a front end portion 11a as an upper end portion in the vertical direction in FIGS. 2 and 4 and a rear end portion 11b as a lower end portion in the vertical direction in FIG. Further, between the front end portion 11a and the rear end portion 11b, there is a narrowed portion 11c having a width in the left-right direction that is narrower than the front end portion 11a and the rear end portion 11b. Thereby, the absorptive core 11 is configured in a plan view substantially hourglass shape as shown in FIGS. 2 and 4 .

表面薄片構件13，是從肌膚側覆蓋吸收性芯11的薄片狀的構件，例如比吸收性芯11更大的平面尺寸的液透過性的不織布。又，裏面薄片構件15，是從非肌膚側覆蓋吸收性芯11的薄片狀的構件，且比吸收性芯11大的平面尺寸的薄片，就其一例來說，可舉貼合聚乙烯或聚丙烯等的液不透過性的防漏薄片15a、與不織布等的外裝薄片15b的二層構造的薄片。The surface sheet member 13 is a sheet-like member that covers the absorbent core 11 from the skin side, and is, for example, a liquid-permeable nonwoven fabric having a larger planar size than the absorbent core 11. Further, the inner sheet member 15 is a sheet-like member that covers the absorbent core 11 from the non-skin side, and has a larger planar size than the absorbent core 11, and an example thereof may be a polyethylene or a poly A liquid-impermeable leakage preventing sheet 15a such as propylene or a sheet having a two-layer structure of an exterior sheet 15b such as a nonwoven fabric.

又，在紙尿褲1，是如圖4所示，藉由外裝薄片15b形成所謂立體褶邊LSG及腿圍褶邊LG。立體褶邊LSG，是在表面薄片構件13的左右方向的各端部各自立起而設的防漏壁部，另一方面，腿圍褶邊LG，是被形成在紙尿褲1的各腿圍開口1HL、1HL的腿圍伸縮部。外裝薄片15b具有從防漏薄片15a的左右方向的兩側朝左右方向延伸出的部分15bf，該部分15bf以吸收性本體10的左右方向的端部作為折疊位置朝左右方向的中央側被折疊，且絲線橡膠等的腿圍彈性構件17及腿圍補助彈性構件19在該折疊位置的附近沿著上下方向朝上下方向被伸長的狀態下被固定，藉此，形成上述的腿圍褶邊LG。此外，腿圍補助彈性構件19並不是一定必要，僅藉由腿圍彈性構件17形成腿圍褶邊LG亦可。Moreover, in the diaper 1, as shown in FIG. 4, the so-called three-dimensional hem LSG and the leg-surround hem LG are formed by the exterior sheet 15b. The three-dimensional hem LSG is a leakage preventing wall portion that is provided at each end portion of the surface sheet member 13 in the left-right direction. On the other hand, the leg hem LG is formed in each leg opening of the diaper 1 . 1HL, 1HL leg circumference expansion and contraction. The exterior sheet 15b has a portion 15bf extending in the left-right direction from both sides in the left-right direction of the leakage preventing sheet 15a, and the portion 15bf is folded in the left-right direction at the end portion of the absorbent body 10 in the left-right direction as a folding position. The leg-hole elastic member 17 and the leg-hole reinforcing elastic member 19 such as the thread rubber are fixed in a state in which the vertical direction is elongated in the vertical direction in the vicinity of the folding position, whereby the leg-surrounding LG is formed. . Further, the leg-surrounding elastic member 19 is not necessarily required, and the leg-surrounding LG may be formed only by the leg-surrounding elastic members 17.

被折疊的部分15bf進一步延伸到左右方向的中央側，而覆蓋表面薄片構件13的左右方向的端部，在上下方向的兩端部與表面薄片構件13接合。再者，部分15bf朝左右方向的兩外側被折疊，在其前端部，絲線橡膠等的LSG彈性構件18沿著上下方向朝上下方向被伸長的狀態下被固定。藉由該LSG彈性構件18在上下方向收縮，以表面薄片構件13側成為內周側地使吸收性本體10朝上下方向彎曲。而且，吸收性本體10的彎曲時，藉由從該LSG彈性構件18所賦予的收縮力，使部分15bf的前端部在上下方向收縮而從表面薄片構件13立起作為立體褶邊LSG發揮功能。The folded portion 15bf is further extended to the center side in the left-right direction, and the end portion covering the left and right direction of the surface sheet member 13 is joined to the surface sheet member 13 at both end portions in the up and down direction. Further, the portion 15bf is folded to the both outer sides in the left-right direction, and the LSG elastic member 18 such as the thread rubber is fixed in the vertical direction in the vertical direction at the tip end portion thereof. By contracting the LSG elastic member 18 in the vertical direction, the absorbent body 10 is bent in the vertical direction so that the surface sheet member 13 side becomes the inner peripheral side. When the absorbent body 10 is bent, the front end portion of the portion 15bf is contracted in the vertical direction by the contraction force applied from the LSG elastic member 18, and the front sheet member 13 rises up to function as a three-dimensional hem LSG.

此外，在某些情況下，也可在表面薄片構件13與吸收性芯11之間，或裏面薄片構件15與吸收性芯11之間(參照圖3）***設置薄紙等的液透過性薄片作為第二薄片。Further, in some cases, a liquid permeable sheet such as a thin paper may be inserted between the surface sheet member 13 and the absorbent core 11 or between the back sheet member 15 and the absorbent core 11 (see Fig. 3). The second sheet.

在吸收性本體10的防漏薄片15a的非肌膚側面設有預定的圖案。在圖4的例子，印刷有熊貓的人物角色(後述的主要圖形101、102)作為圖案的一例。該圖案，是設成透過外裝薄片15b從非肌膚側(亦即，紙尿褲1的外側)可視認。此外，在圖4的俯視圖，為了說明畫成從吸收性本體10的肌膚側(紙尿褲1的內側)也可視認該圖案(主要圖形101、102)。以下，也將被印刷的圖案稱呼為「圖形」。關於圖形的大小、配置的詳細在之後進行說明。A predetermined pattern is provided on the non-skin side of the leakage preventing sheet 15a of the absorbent body 10. In the example of FIG. 4, a character of a panda (main patterns 101 and 102 which will be described later) is printed as an example of a pattern. This pattern is visually recognized from the non-skin side (that is, the outer side of the diaper 1) through the exterior sheet 15b. In addition, in the top view of FIG. 4, the pattern (main pattern 101, 102) is also visible from the skin side of the absorbent body 10 (inside of the diaper 1). Hereinafter, the printed pattern is also referred to as "graphics". The details of the size and arrangement of the graphics will be described later.

另一方面，在吸收性本體10的防漏薄片15a的肌膚側面，設有成為告知紙尿褲1的使用者(例如嬰幼兒的照護者)尿等的液體的吸收量的指標的指示部60。指示部60，是由圖4的虛線所圍起來的區域所表示，在左右方向的中央部沿著上下方向(吸收性本體的長邊方向)形成帶狀。該指示部60，是由藉由與水分接觸而使顏色進行變化的物質(墨水)所形成，嬰幼兒等的穿用對象者穿用紙尿褲1的狀態下進行排尿的話，藉由吸收性芯11所吸收的尿與指示部60接觸使顏色進行變化。因此，使用者(嬰幼兒的照護者)藉由從紙尿褲1的外側視認指示部60的顏色的變化，容易掌握紙尿褲1的更換時間。On the other hand, on the skin side surface of the leakage preventing sheet 15a of the absorbent body 10, an instruction unit 60 that is an indicator for informing the user of the diaper 1 (for example, a caregiver of an infant) of the amount of absorption of liquid such as urine is provided. The indication portion 60 is indicated by a region surrounded by a broken line in FIG. 4, and is formed in a strip shape in the vertical direction (longitudinal direction of the absorbent body) in the center portion in the left-right direction. The indicator unit 60 is formed of a substance (ink) that changes its color by contact with water. When the wearer of the infant or the like wears the diaper 1 and urinates, the absorbent core 11 is used. The absorbed urine contacts the indicator portion 60 to change the color. Therefore, the user (the caregiver of the infant) can easily grasp the replacement time of the diaper 1 by visually recognizing the change in the color of the indication portion 60 from the outside of the diaper 1.

(帶構件30、40) 　　前側帶構件30及後側帶構件40皆例如以不織布等的柔軟的薄片作為素材的俯視觀看大致矩形形狀的薄片構件(參照圖2)。(Band members 30 and 40) Each of the front side belt member 30 and the rear side belt member 40 is a sheet member having a substantially rectangular shape as viewed from a soft sheet such as a non-woven fabric (see FIG. 2).

前側帶構件30，是如圖3所示，將不織布31、32兩片重疊在厚度方向加以接合而可形成。而且，在2片的不織布31、32彼此之間，沿著左右方向配置有絲線橡膠等的複數個腰圍彈性構件35、35…。腰圍彈性構件35、35…，是邊介插排列在上下方向分開間隔邊在上下方向，邊朝左右方向被伸長的狀態下被接合固定在該不織布31、32。藉此，在前側帶構件30成為在左右方向可伸縮性。此外，不織布31與32，是隔著由熱熔式接著劑等的接著劑所形成的帶構件接合部37互相被接合。帶構件接合部37例如被形成在由圖2的網點部所示的帶構件接合部37a及37b的範圍，藉由該帶構件接合部37a及37b接合固定腰圍彈性構件35，對前側帶構件30賦予左右方向的伸縮性。可是，形成帶構件接合部37的範圍、大小不限於此。As shown in FIG. 3, the front side belt member 30 can be formed by laminating two sheets of non-woven fabrics 31 and 32 in the thickness direction. Further, a plurality of waist elastic members 35, 35, ... such as a thread rubber are disposed between the two nonwoven fabrics 31 and 32 in the left-right direction. The waist elastic members 35, 35, ... are joined and fixed to the nonwoven fabrics 31 and 32 in a state in which they are stretched in the vertical direction in the vertical direction while being spaced apart in the vertical direction. Thereby, the front side belt member 30 is stretchable in the left-right direction. Further, the nonwoven fabrics 31 and 32 are joined to each other via a belt member joint portion 37 formed of an adhesive such as a hot melt adhesive. The belt member joint portion 37 is formed, for example, in the range of the belt member joint portions 37a and 37b shown by the halftone dot portion of Fig. 2, and the belt member joint portions 37a and 37b are joined to fix the waist elastic member 35, and the front side belt member 30 is attached. Provides flexibility in the right and left direction. However, the range and size of the belt member joint portion 37 are not limited thereto.

在本實施形態，腰圍彈性構件35的至少一部分具有在左右方向的中央部成為不連續的部分。腰圍彈性構件35的不連續部，是藉由在紙尿褲1的製造過程在左右方向的中央部的預定之處切斷腰圍彈性構件35而被形成。具體而言，在左右方向在對被形成在兩側一對帶構件接合部37b、37b之間的區域，切斷腰圍彈性構件35。於是，腰圍彈性構件35，是從被切斷之處(切斷端)朝向左右方向兩側的帶構件接合部37b開始收縮，在帶構件接合部37b的左右方向內側端的位置停止收縮。也將該動作稱為彈性構件的「反向動作」。在本實施形態，在左右方向在帶構件接合部37b、37b之間的區域，沒有接著腰圍彈性構件35(或是，用伸縮力不作用的程度的弱的接著力被接合亦可)。因此，腰圍彈性構件35進行反向動作時，構成前側帶構件30的不織布31、32不收縮，僅腰圍彈性構件35朝向左右方向的兩側收縮。換言之，腰圍彈性構件35相對於前側帶構件30相對進行位移。藉此，紙尿褲1的前側(腹側)，在左右方向中央部形成有腰圍彈性構件35的不連續部。在該不連續部，相對於吸收性本體10(吸收性芯11)，左右方向中的收縮力不易作用，吸收性本體10(吸收性芯11)容易朝向左右方向擴寬，所以可有效果地抑制***物的側漏等。In the present embodiment, at least a part of the waist elastic member 35 has a discontinuous portion in the center portion in the left-right direction. The discontinuous portion of the waist elastic member 35 is formed by cutting the waist elastic member 35 at a predetermined portion in the center portion in the left-right direction during the manufacturing process of the diaper 1. Specifically, the waist elastic member 35 is cut in the right and left direction in a region formed between the pair of belt member joint portions 37b and 37b on both sides. Then, the waist elastic member 35 starts to shrink from the cut position (cut end) toward the belt member joint portion 37b on both sides in the left-right direction, and stops contracting at the position of the inner side end of the belt member joint portion 37b in the left-right direction. This action is also referred to as the "reverse action" of the elastic member. In the present embodiment, the waist elastic member 35 is not attached to the region between the belt member joint portions 37b and 37b in the left-right direction (or a weak adhesive force to which the expansion and contraction force does not act may be joined). Therefore, when the waist elastic member 35 performs the reverse operation, the nonwoven fabrics 31 and 32 constituting the front side belt member 30 do not contract, and only the waist elastic member 35 contracts toward both sides in the left-right direction. In other words, the waist elastic member 35 is relatively displaced with respect to the front side belt member 30. Thereby, the front side (ventral side) of the diaper 1 is formed with the discontinuous part of the waist elastic member 35 in the center part of the left-right direction. In the discontinuous portion, the contraction force in the left-right direction does not easily act on the absorbent main body 10 (absorbent core 11), and the absorbent main body 10 (absorbent core 11) is easily widened in the left-right direction, so that it is effective. Suppress side leakage of excreta, etc.

又，在前側帶構件30的上下方向的上側(腰圍開口側)，非肌膚側的不織布32比肌膚側的不織布31的縱向上端更朝上側突出，朝肌膚側折疊突出的部分形成前側翻折部32f，該前側翻折部32f被接合固定在不織布31的肌膚側(參照圖3)。藉此，藉由前側翻折部32f覆蓋前側帶構件30的上端30ea，在紙尿褲1的穿用時，上端30ea的邊緣不易陷入穿用者的肌膚(腹側腰圍部)，可不易產生穿用時的不舒適感。In the upper side (waist opening side) of the front side belt member 30 in the vertical direction, the non-skin-side non-woven fabric 32 protrudes upward from the longitudinal upper end of the skin-side non-woven fabric 31, and the portion that folds toward the skin side forms the front side folding portion. 32f, the front side folded portion 32f is joined and fixed to the skin side of the nonwoven fabric 31 (see Fig. 3). Thereby, the upper end 30ea of the front side belt member 30 is covered by the front side folding portion 32f, and the edge of the upper end 30ea is less likely to fall into the wearer's skin (ventral waist portion) when the diaper 1 is worn, which is less likely to be worn. The sense of discomfort.

前側帶構件30經由前側本體接合部51被接合在吸收性本體10的前側上端部(圖3中的非肌膚側且為腰圍開口側的端部)。前側本體接合部51，是使用熔著、接著等的接合手段所形成，在本實施形態，是使用例如熱熔接著劑等的接著劑形成前側本體接合部51。The front side belt member 30 is joined to the front upper end portion of the absorbent body 10 via the front side body joint portion 51 (the non-skin side in FIG. 3 and is the end portion on the waist opening side). The front body joint portion 51 is formed by a bonding means such as welding or the like. In the present embodiment, the front body joint portion 51 is formed using an adhesive such as a hot melt adhesive.

後側帶構件40具有與前側帶構件30大致同樣的構造。亦即，後側帶構件40，是將不織布41、42兩片重疊在厚度方向加以接合而被形成，在不織布41、42的厚度方向之間經由帶構件接合部47(圖2中的帶構件接合部47a及47b)朝左右方向伸長絲線橡膠等的複數個腰圍彈性構件45、45的狀態下被接合固定。藉此，在後側帶構件40賦予左右方向的伸縮性。又，腰圍彈性構件45的至少一部分，是與腰圍彈性構件35同樣在左右方向的中央部被切斷而進行反向動作，藉此形成不連續部。因此，即使在後側(背側)的不連續部，因為相對於吸收性本體10(吸收性芯11)朝左右方向的收縮力不易作用，吸收性本體10(吸收性芯11)容易朝向左右方向被擴寬，所以可有效果地抑制***物的側漏等。The rear side belt member 40 has substantially the same configuration as the front side belt member 30. In other words, the rear side belt member 40 is formed by laminating two sheets of the nonwoven fabrics 41 and 42 in the thickness direction, and passes between the non-woven fabrics 41 and 42 in the thickness direction via the belt member joint portion 47 (the belt member in Fig. 2). The joint portions 47a and 47b) are joined and fixed in a state in which a plurality of waist elastic members 45 and 45 such as a thread rubber are elongated in the left-right direction. Thereby, the rear side belt member 40 is provided with the stretchability in the left-right direction. In addition, at least a part of the waist elastic member 45 is cut in the center portion in the left-right direction similarly to the waist elastic member 35, and reverse operation is performed, thereby forming a discontinuous portion. Therefore, even in the discontinuous portion on the rear side (back side), since the contraction force in the left-right direction with respect to the absorbent body 10 (absorbent core 11) does not easily act, the absorbent body 10 (absorbent core 11) tends to face left and right. Since the direction is widened, side leakage of the excrement or the like can be effectively suppressed.

又，在後側帶構件40的上下方向的上側(腰圍開口側)，非肌膚側的不織布42比肌膚側的不織布41的上下方向上端更朝上側突出，朝肌膚側折疊突出的部分而形成後側翻折部42f。In the upper side (waist opening side) of the rear side belt member 40, the nonwoven fabric 42 on the non-skin side protrudes upward from the upper end in the up-and-down direction of the non-woven fabric 41 on the skin side, and is formed by folding the protruding portion toward the skin side. Side folded portion 42f.

後側帶構件40經由後側本體接合部52被接合在吸收性本體10的後側上端部(圖3中的非肌膚側且為腰圍開口側的端部)。The rear side belt member 40 is joined to the rear upper end portion of the absorbent body 10 via the rear side body joint portion 52 (the non-skin side in FIG. 3 and the end portion on the waist opening side).

此外，在圖3設有從肌膚側覆蓋吸收性本體10的前側上端10ea、及前側翻折部32f的下端32feb的薄片構件38。藉由該薄片構件38，在紙尿褲1的穿用時，前側上端10ea及下端32feb的邊緣不易陷入穿用者的肌膚，可不易產生穿用時的不舒適感。同樣，設有從肌膚側覆蓋吸收性本體10的後側上端10eb、及後側翻折部42f的下端42feb的薄片構件48。藉由該薄片構件48，在紙尿褲1的穿用時，後側上端10eb及下端42feb的邊緣不易陷入穿用者的肌膚，可不易產生穿用時的不舒適感。可是，在紙尿褲1，薄片構件38、48也沒有一定要設置。Further, in Fig. 3, a sheet member 38 that covers the front upper end 10ea of the absorbent body 10 and the lower end 32feb of the front folded portion 32f from the skin side is provided. By the sheet member 38, when the diaper 1 is worn, the edges of the front upper end 10ea and the lower end 32feb are less likely to fall into the wearer's skin, and the discomfort during wearing is less likely to occur. Similarly, a sheet member 48 that covers the rear upper end 10eb of the absorbent body 10 and the lower end 42feb of the rear folded portion 42f from the skin side is provided. By the sheet member 48, when the diaper 1 is worn, the edges of the rear upper end 10eb and the lower end 42feb are less likely to fall into the wearer's skin, and the discomfort during wearing is less likely to occur. However, in the diaper 1, the sheet members 38, 48 are not necessarily provided.

＜圖形的說明＞ 　　針對設在吸收性本體10的防漏薄片15a的非肌膚側面的圖形進行說明。圖形，是在紙尿褲1的製造工程，例如藉由使用噴墨印刷機等的一般的印刷裝置對防漏薄片15a進行印刷而被形成。<Description of Pattern> A pattern of the non-skin side surface of the leakage preventing sheet 15a provided in the absorbent body 10 will be described. The figure is formed in the manufacturing process of the diaper 1, for example, by printing the leakage preventing sheet 15a by using a general printing apparatus such as an inkjet printer.

在防漏薄片15a的非肌膚側面，可形成插圖、照片；花紋；文字等各種的圖形。亦即，針對形狀、色彩、大小、配置等可印刷各式各樣的設計的圖案。在圖4的例子，雖印刷有熊貓的人物角色，可是除了該人物角色以外，也可印刷其他的圖形(例如花紋等)。On the non-skin side of the leakage preventing sheet 15a, various patterns such as illustrations, photographs, patterns, and characters can be formed. That is, a variety of designs can be printed for shapes, colors, sizes, configurations, and the like. In the example of FIG. 4, although a character of a panda is printed, other figures (for example, a pattern, etc.) may be printed in addition to the character.

在本實施形態，將被印刷在防漏薄片15a的非肌膚側面的圖形中滿足所定的條件圖形稱呼為「主要圖形」。具體而言，「主要圖形」，是表示被印刷在防漏薄片15a的非肌膚側面的圖形中，針對將吸收性本體10朝上下方向及左右方向伸長的狀態中的前側面、或是後側面的至少一方側的面，顯示被印刷在面積的40%以上的區域的圖形。此外，「前側面」，是指在折疊位置C10對折吸收性本體10時，位在前側的面，在圖4，是在吸收性本體10的長邊方向比折疊位置C10更靠腹側的面。同樣，「後側面」，是指在折疊位置C10對折吸收性本體10時，位在後側的面，在圖4，是在吸收性本體10的長邊方向比折疊位置C10更靠背側的面。In the present embodiment, the pattern that is printed on the non-skin side surface of the leakage preventing sheet 15a satisfies the predetermined condition pattern as the "main pattern". Specifically, the "main pattern" is a front side or a rear side in a state in which the absorbent body 10 is stretched in the up-down direction and the left-right direction in the pattern of the non-skin side surface of the leakage preventing sheet 15a. The surface on at least one side shows a pattern printed in an area of 40% or more of the area. In addition, the "front side" refers to the surface on the front side when the absorbent body 10 is folded in the folded position C10, and the front side of the absorbent body 10 in the longitudinal direction of the absorbent body 10 is closer to the front side than the folded position C10. . Similarly, the "rear side surface" refers to the surface on the rear side when the absorbent body 10 is folded in the folded position C10, and the back side of the absorbent body 10 in the longitudinal direction of the absorbent body 10 is more than the folded position C10. .

在圖4的例子，是在吸收性本體10(防漏薄片15a)的前側面形成有由拿著氣球的熊貓的人物角色形成的前側主要圖形101。另一方面，在吸收性本體10(防漏薄片15a)的後側面形成有由親子熊貓的人物角色形成的後側主要圖形102。可是，主要圖形沒有必要一定被形成在前側面與後側面的兩面，由於僅在任一一方側的面(期望是後側面)形成有主要圖形亦可。In the example of Fig. 4, a front main pattern 101 formed of a person character of a panda holding a balloon is formed on the front side surface of the absorbent body 10 (leak-proof sheet 15a). On the other hand, a rear main pattern 102 formed by a persona of a parent-child panda is formed on the rear side surface of the absorbent body 10 (leak-proof sheet 15a). However, the main pattern does not necessarily have to be formed on both sides of the front side and the rear side, and the main pattern may be formed only on the surface of one of the sides (desired to be the rear side).

這樣的主要圖形，是佔吸收性本體10的前側面或後側面的40%以上的面積，由於在紙尿褲1穿用時為最容易引人注意的圖形，所以，為嬰幼兒、其照護者容易認識這樣的人物角色的圖案為期望。而且，因為更容易認識與紙尿褲1的關連性，所以，主要圖形，是與讓紙尿褲1在市場流通時畫在包裝袋的人物角色同樣的人物角色的圖案更為期望。Such a main pattern is an area of 40% or more of the front side or the rear side of the absorbent body 10, and is the most easily noticeable figure when the diaper 1 is worn, so it is easy for infants and their caregivers. It is expected to recognize the pattern of such personas. Moreover, since it is easier to recognize the connection with the diaper 1, the main figure is more desirable than the pattern of the persona who draws the character of the bag when the diaper 1 is distributed in the market.

又，主要圖形，是複數個圖案聚集而形成聚在一起的圖案者亦可。例如，圖4所示的前側主要圖形101雖是乘著雲的小熊貓拿著2個氣球的圖案，可是，「雲」與「小熊貓」和「氣球」，是由連續的線形成圍起來的閉鎖區域。這樣的時候，不僅作為人物角色的「小熊貓」，就連「雲」、「氣球」也成為主要圖形的構成要素，全部的構成要素加起來的面積只要是吸收性本體10的前側面的40%以上的大小即可。例如，與某人物角色重疊形成背景、文字等的時候，該等的要素聚在一起而構成主要圖形。此外，主要圖形的輪廓也可不必一定為閉鎖區域，輪廓線的一部分也可中途斷掉。例如，在圖4的前側主要圖形101，「雲」一部分的輪廓中途斷掉這樣的時候，只要使用者一看就可認識是聚在一起的圖案，該「雲」也成為主要圖形的構成要素。Moreover, the main figure is a pattern in which a plurality of patterns are gathered to form a gathered pattern. For example, the front main pattern 101 shown in FIG. 4 is a pattern of two balloons held by a little panda riding a cloud, but "cloud" and "little panda" and "balloon" are surrounded by continuous lines. The locked area. In this case, not only the "little panda" as a character, but also "cloud" and "balloon" are constituent elements of the main figure. The area in which all the components are added is only 40 of the front side of the absorbent body 10. More than % of the size can be. For example, when a person character is superimposed to form a background, a character, or the like, the elements are grouped together to form a main figure. In addition, the outline of the main figure does not have to be a locked area, and a part of the outline can also be cut off halfway. For example, in the front main pattern 101 of FIG. 4, when the outline of a part of the "cloud" is broken in the middle, the user can recognize the pattern that is gathered together as soon as the user sees it, and the "cloud" also becomes a constituent element of the main figure. .

又，圖4所示的後側主要圖形102，是大熊貓與小熊貓排列被配置的圖案。此時，藉由「大熊貓」與「小熊貓」的連續線形成圍起來的閉鎖區域，藉由2個人物角色構成主要圖形。而且，該2個人物角色合起來的面積只要是吸收性本體10的後側面的40%以上的大小即可。此外，如後側主要圖形102，含有複數個人物角色(在圖4，是熊貓)作為主要圖形的構成要素時，在左右方向(吸收性本體10的寬邊方向)排列配置有該複數個人物角色為期望。又，即使複數個人物角色彼此被配置在互相分開的位置時，該複數個人物角色為聚在一起的圖案時，該等複數個人物角色構成主要圖形。例如，在後側主要圖形102，可明白是「大熊貓」與「小熊貓」排列的一系列的「親子熊貓」。因此，假使「大熊貓」與「小熊貓」互相分開被配置，該2個人物角色構成後側主要圖形102。Moreover, the rear main pattern 102 shown in FIG. 4 is a pattern in which a giant panda and a red panda are arranged. At this time, the enclosed area of the "Giant Panda" and the "Little Panda" forms a closed area, and the main characters are composed of two personal characters. Further, the area in which the two personal characters are combined may be a size of 40% or more of the rear side surface of the absorbent main body 10. Further, when the rear main pattern 102 includes a plurality of personal characters (a panda in FIG. 4) as a constituent element of the main pattern, the plurality of personal objects are arranged side by side in the left-right direction (the broad side direction of the absorptive main body 10). The role is expected. Further, even when the plurality of personal character roles are arranged at positions separated from each other, when the plurality of personal character characters are gathered together, the plurality of personal character characters constitute a main figure. For example, in the rear main graphic 102, it can be understood that a series of "family pandas" arranged by "Giant Panda" and "Little Panda". Therefore, if the "Giant Panda" and the "Little Panda" are arranged separately from each other, the two personal characters constitute the rear main pattern 102.

於此，針對算出主要圖形的面積相對於吸收性本體10的前側面(或是後側面)的面積的比例(%)的方法的一例進行說明。首先，將成為面積的算出對象的紙尿褲朝上下方向及左右方向伸長，使用市售的攝相機拍攝吸收性本體10的前側面及後側面。然後，讓掃描器讀取所拍攝的影像，取得讀取的數據。該讀取的數據，是依照掃描器讀取的解析度的畫素數據排列成2次元的數據，各畫素數據，是針對吸收性本體10及主要圖形的各部位以多階段的色調值(以下，讀取的色調值)表示濃度(印刷濃度)者。該畫素數據所示的讀取的色調值愈大，印刷濃度濃，讀取的色調值愈小，印刷濃度淡。此外，畫素數據所示的讀取色調值，例如也可藉由亮度、L＊值(明度)表示。Here, an example of a method of calculating the ratio (%) of the area of the main pattern to the area of the front side surface (or the rear side surface) of the absorptive main body 10 will be described. First, the diaper which is the object of calculation of the area is extended in the up-down direction and the left-right direction, and the front side surface and the rear side surface of the absorptive main body 10 are image|photographed using the camera. Then, let the scanner read the captured image and obtain the read data. The read data is data arranged in two dimensions in accordance with the pixel data of the resolution read by the scanner, and each pixel data is a multi-stage tone value for each part of the absorptive body 10 and the main pattern ( Hereinafter, the read tone value) indicates the density (printing density). The pixel value indicated by the pixel data is larger, the printing density is rich, and the read tone value is smaller, and the printing density is light. Further, the read tone value indicated by the pixel data may be expressed by, for example, luminance and L* value (lightness).

接著，針對讀取的數據進行主要圖形的邊緣抽取處理。在邊緣抽取處理，是適用例如拉普拉斯濾波器、sobel濾波器等的周知的濾波器，抽取形成主要圖形的輪廓的畫素予以2值化。其結果，用最大色調(255)表示形成主要圖形的輪廓的畫素的色調值，用最低色調(0)表示這以外的畫素的色調值。如上述，主要圖形由於是由基本上連續的線所圍起來的閉鎖區域，所以，藉由算出在讀取的數據中所抽取的輪廓畫素所圍起來的區域的面積，可正確測量主要圖形的面積。此外，主要圖形的輪廓線中途斷掉的情況，藉由在讀取的數據上形成・追加假想輪廓線，算出主要圖形的面積即可。同樣，吸收性本體10的前側面(後側面)的面積也從讀取的數據進行測量，藉此可算出主要圖形的面積佔前側面(後側面)的比例(%)。當然，可藉由這以外的方法算出主要圖形的面積的比例(%)。Next, edge extraction processing of the main graphics is performed on the read data. In the edge extraction processing, a well-known filter such as a Laplacian filter or a sobel filter is applied, and a pixel forming a contour of a main pattern is extracted and binarized. As a result, the tone value of the pixel forming the outline of the main pattern is represented by the maximum color tone (255), and the tone value of the other pixels is represented by the lowest color tone (0). As described above, since the main pattern is a closed area surrounded by substantially continuous lines, the main figure can be correctly measured by calculating the area of the area enclosed by the outline pixels extracted in the read data. Area. In addition, when the outline of the main figure is broken in the middle, the area of the main figure can be calculated by forming and adding a virtual outline to the read data. Similarly, the area of the front side (rear side) of the absorbent body 10 is also measured from the read data, whereby the ratio (%) of the area of the main pattern to the front side (rear side) can be calculated. Of course, the ratio (%) of the area of the main pattern can be calculated by other methods.

＜關於主要圖形的配置＞ 　　紙尿褲1，是藉由調整設在吸收性本體10的非肌膚側的主要圖形101、102的視認性，可讓使用者容易理解構成紙尿褲1的各構件，尤其，前側帶構件30及後側帶構件40具有充分的強度。以下，針對主要圖形的具體的配置進行說明。圖5A，是針對紙尿褲1的前側面中的前側主要圖形101的配置進行說明的圖。圖5B，是針對紙尿褲1的後側面中的後側主要圖形102的配置進行說明的圖。在該圖5A及圖5B，是針對將形成短褲型的紙尿褲1朝上下方向及左右方向伸長後的狀態(伸長狀態)進行表示。圖6，是表示穿用紙尿褲1的嬰幼兒進行爬行的樣子的圖。圖7，是針對短褲型形態的紙尿褲1的剖面狀態進行說明的圖。<Arrangement of Main Patterns> The diaper 1 allows the user to easily understand the members constituting the diaper 1 by adjusting the visibility of the main patterns 101 and 102 provided on the non-skin side of the absorbent body 10, in particular, the front side. The belt member 30 and the rear side belt member 40 have sufficient strength. Hereinafter, a specific configuration of the main figure will be described. FIG. 5A is a view for explaining the arrangement of the front main pattern 101 in the front side surface of the diaper 1. FIG. 5B is a view for explaining the arrangement of the rear main pattern 102 in the rear side surface of the diaper 1. 5A and FIG. 5B show the state (elongation state) in which the pants-type diaper 1 which formed the pants type is extended in the up-down direction and the left-right direction. Fig. 6 is a view showing a state in which an infant wearing the diaper 1 crawls. FIG. 7 is a view for explaining a cross-sectional state of the diaper 1 of the pants type.

如圖5A所示，吸收性本體10的前側面在上下方向的上側(腰圍開口側)，一部分的區域與前側帶構件30重複。在吸收性本體10的前側面，將與前側帶構件30重複的部分作為前側重複部10fu，將不重複的部分作為前側不重複部10fd。又，如圖5B所示，吸收性本體10的後側面在上下方向的上側(腰圍開口側)，一部分的區域與後側帶構件40重複。在吸收性本體10的後側面，將與後側帶構件40重複的部分作為後側重複部10bu，將不重複的部分作為後側不重複部10bd。As shown in FIG. 5A, the front side surface of the absorbent body 10 is on the upper side in the up-and-down direction (side of the waist opening side), and a part of the area is overlapped with the front side belt member 30. On the front side surface of the absorbent body 10, a portion overlapping the front side belt member 30 is referred to as a front side repeating portion 10fu, and a portion not overlapping is referred to as a front side non-repetitive portion 10fd. Further, as shown in FIG. 5B, the rear side surface of the absorbent body 10 is on the upper side in the vertical direction (side of the waist opening side), and a part of the area is overlapped with the rear side belt member 40. On the rear side surface of the absorbent body 10, a portion overlapping the rear side belt member 40 is referred to as a rear side repeating portion 10bu, and a non-overlapping portion is referred to as a rear side non-repetitive portion 10bd.

在本實施形態，配置前側主要圖形101，使前側主要圖形101與前側帶構件30重複的部分的面積成為前側主要圖形101的面積的50%以上。換言之，前側主要圖形101中，50%以上的區域被配置在前側重複部10fu。同樣，後側主要圖形102與後側帶構件40重複的部分的面積，是後側主要圖形102的面積的50%以上，後側主要圖形102中50%以上的區域被配置在後側重複部10bu。In the present embodiment, the front main pattern 101 is disposed such that the area of the portion where the front main pattern 101 and the front side belt member 30 overlap is 50% or more of the area of the front main pattern 101. In other words, in the front main pattern 101, 50% or more of the area is disposed in the front side repeating portion 10fu. Similarly, the area of the portion where the rear side main pattern 102 and the rear side belt member 40 overlap is 50% or more of the area of the rear side main pattern 102, and the area of the rear side main pattern 102 of 50% or more is disposed in the rear side repeating portion. 10bu.

在該前側重複部10fu、後側重複部10bu，帶構件30、40重疊在主要圖形101、102的非肌膚側被配置。亦即，在該區域，在主要圖形101、102的厚度方向的非肌膚側層積有複數個不織布(15b；31、32；41、42等)被配置。從外側觀看這樣的紙尿褲1的時候，在主要圖形101、102與帶構件30、40重複的區域，形成透過該帶構件30、40能視認主要圖形101、102。因此，在帶構件30、40重複的區域，主要圖形101、102的視認性降低。In the front side overlapping portion 10fu and the rear side overlapping portion 10bu, the belt members 30 and 40 are placed on the non-skin side of the main patterns 101 and 102. In other words, in this region, a plurality of non-woven fabrics (15b; 31, 32; 41, 42, etc.) are stacked on the non-skin side in the thickness direction of the main patterns 101 and 102. When such a diaper 1 is viewed from the outside, the main patterns 101 and 102 can be visually recognized through the belt members 30 and 40 in a region where the main patterns 101 and 102 overlap with the belt members 30 and 40. Therefore, in the region where the belt members 30, 40 are repeated, the visibility of the main patterns 101, 102 is lowered.

具體而言，在主要圖形101、102與帶構件30、40重複的區域，形成主要圖形101、102的顏色看起來淡、或輪廓看起來模糊。如此，與帶構件30、40重複，而刻意讓主要圖形101、102的視認性降低，藉此，可讓使用者(嬰幼兒的照護者等)確實認識帶構件30、40的存在。而且，與帶構件30、40重複的區域中的主要圖形101、102的視認性愈降低，成為容易認識帶構件30、40的厚度，可抑制使用者對帶構件30、40的強度感到不安的情況。Specifically, in a region where the main patterns 101, 102 overlap with the belt members 30, 40, the colors forming the main patterns 101, 102 appear pale, or the outlines appear blurred. As described above, the tape members 30 and 40 are repeatedly arranged to deliberately reduce the visibility of the main patterns 101 and 102, whereby the user (the caregiver of the infant or the like) can surely recognize the presence of the belt members 30 and 40. Further, the visibility of the main patterns 101 and 102 in the region overlapping the belt members 30 and 40 is lowered, and the thickness of the belt members 30 and 40 is easily recognized, and the user is prevented from feeling uncomfortable with the strength of the belt members 30 and 40. Happening.

此外，為了使主要圖形101、102的視認性的降低程度明確，主要圖形101、102分別被形成在與帶構件30、40重複的區域、以及不重複的區域的兩方的區域為期望。亦即，前側主要圖形101，是跨前側重複部10fu與前側不重複部10fd的邊界被形成為期望(參照圖5A)。同樣，後側主要圖形102，是跨後側重複部10bu與後側不重複部10bd的邊界被形成為期望(參照圖5B)。Further, in order to clarify the degree of visibility of the main patterns 101 and 102, it is desirable that the main patterns 101 and 102 are formed in a region overlapping each of the belt members 30 and 40 and a region not overlapping. That is, the front main pattern 101 is formed to be desired along the boundary between the front side overlapping portion 10fu and the front side non-repeat portion 10fd (see FIG. 5A). Similarly, the rear main pattern 102 is formed to be desired across the boundary between the rear side repeating portion 10bu and the rear side non-repeatd portion 10bd (see FIG. 5B).

根據這樣的結構，在沒有與帶構件30、40重複的區域，主要圖形101、102看起來鮮明，而相對於此，在與帶構件30、40重複的區域，主要圖形101、102的視認性看起來下降的情況變的明確。亦即，如圖1、圖5所示，在前側主要圖形101中與前側帶構件30重複的部分、和不重複的部分視認性的差明確，可更容易認識前側帶構件30的厚度。According to such a configuration, the main patterns 101 and 102 appear sharp in a region where the belt members 30 and 40 are not overlapped, whereas the visibility of the main patterns 101 and 102 in the region overlapping with the belt members 30 and 40 is opposite. It seems that the situation of decline has become clear. That is, as shown in FIG. 1 and FIG. 5, the difference between the portion overlapping the front side belt member 30 in the front main pattern 101 and the portion of the front side belt member 30 is clear, and the thickness of the front side belt member 30 can be more easily recognized.

又，在紙尿褲1，主要圖形101、102的至少一部分與帶構件接合部37、47沒有重複。例如，在圖5A，前側主要圖形101具有與帶構件接合部37a及37b皆不重複的部分。在紙尿褲1的穿用時，前側帶構件30因腰圍彈性構件35的伸縮力而朝左右方向收縮時，在沒有形成帶構件接合部37的區域，因為肌膚側的不織布31與非肌膚側的不織布32沒有互相被接合，所以，各個不織布個別收縮，容易朝厚度方向浮起。如此，在不織布31、32朝厚度方向浮起的部分，前側主要圖形101的視認性進一步降低，所以，使用者容易認識前側帶構件30的厚度。又，藉由不織布31、32朝厚度方向浮起，強調前側帶構件30的立體感，可讓使用者想起鬆軟的觸感的感覺。關於圖5B的後側主要圖形102也同樣。因此，藉由主要圖形101、102的至少一部分與帶構件接合部37、47沒有重複，可讓使用者感到帶構件30、40既具有充分的強度，又具有柔軟的肌膚觸感。Further, in the diaper 1, at least a part of the main patterns 101, 102 and the belt member joint portions 37, 47 are not overlapped. For example, in Fig. 5A, the front side main pattern 101 has a portion that does not overlap with the belt member joint portions 37a and 37b. When the diaper 1 is worn, when the front side belt member 30 is contracted in the left-right direction by the stretching force of the waist elastic member 35, the area where the belt member joint portion 37 is not formed, because the non-woven fabric 31 on the skin side and the non-woven side on the non-skin side Since 32 is not joined to each other, each of the non-woven fabrics shrinks individually and easily floats in the thickness direction. As described above, in the portion where the nonwoven fabrics 31 and 32 are floated in the thickness direction, the visibility of the front main pattern 101 is further lowered, so that the user can easily recognize the thickness of the front side belt member 30. Moreover, the non-woven fabrics 31 and 32 float in the thickness direction, and the three-dimensional feeling of the front side belt member 30 is emphasized, and the user can feel the feeling of a soft touch. The same applies to the rear main pattern 102 of Fig. 5B. Therefore, by not overlapping at least a part of the main patterns 101 and 102 with the belt member joints 37 and 47, the user can feel that the belt members 30 and 40 have both sufficient strength and a soft skin feel.

又，在紙尿褲1，形成帶構件30、40的不織布的基重比形成吸收性本體10的外裝薄片15b的不織布的基重更大。於此，「基重」，是每單位面積的質量，一般，不織布的面積相同時，愈是基重大的不織布，光透過性愈容易變小。於此，藉由盡量增大帶構件30、40的基重(縮小光透過性)，可讓主要圖形101、102中與帶構件30、40重複的部分的視認性更降低。Further, in the diaper 1, the basis weight of the nonwoven fabric forming the belt members 30, 40 is larger than the basis weight of the nonwoven fabric forming the exterior sheet 15b of the absorbent body 10. Here, the "basis weight" is the mass per unit area. Generally, when the area of the non-woven fabric is the same, the more the non-woven fabric is, the more the light transmittance is reduced. Here, by making the basis weight (reducing light transmittance) of the belt members 30 and 40 as large as possible, the visibility of the portions of the main patterns 101 and 102 that overlap with the belt members 30 and 40 can be made lower.

例如，在吸收性本體10的前側面，在前側不重複部10fd層積在主要圖形101的非肌膚側的薄片構件只有外裝薄片15b。另一方面，在前側重複部10fu，是在前側主要圖形101的非肌膚側層積有外裝薄片15b、不織布31、不織布32的3片的薄片構件(參照圖7)。這樣的結構中，藉由縮小外裝薄片15b的基重，增大不織布31、32的基重，在前側不重複部10fd透過外裝薄片15b容易看到前側主要圖形101，在前側重複部10fu因為前側帶構件30不易透過，所以，前側主要圖形101不易看見。因此，可讓使用者更容易認識前側帶構件30的厚度。關於後側帶構件40也同樣。For example, on the front side surface of the absorbent body 10, the sheet member which is laminated on the non-skin side of the main pattern 101 on the front side non-repeating portion 10fd has only the exterior sheet 15b. On the other hand, in the front side repeating portion 10fu, three sheet members of the outer sheet 15b, the nonwoven fabric 31, and the non-woven fabric 32 are laminated on the non-skin side of the front main pattern 101 (see FIG. 7). In such a configuration, by reducing the basis weight of the exterior sheet 15b, the basis weight of the nonwoven fabrics 31 and 32 is increased, and the front side main pattern 101 is easily seen through the front side non-repeating portion 10fd through the exterior sheet 15b, and the front side repeating portion 10fu is easily seen. Since the front side belt member 30 is not easily transmitted, the front side main pattern 101 is not easily seen. Therefore, the thickness of the front side belt member 30 can be more easily recognized by the user. The same applies to the rear side belt member 40.

又，主要圖形101、102，是以與進行反向動作後的腰圍彈性構件35、45的連續部分(亦即，腰圍彈性構件35、45所致的張力作用的部分)與至少一部分重複地被配置。在該連續部分，藉由腰圍彈性構件35、45進行收縮，而使帶構件35、45邊朝左右方向收縮邊在厚度方向形成具有凹凸的複數個皺紋。亦即、帶構件30、40的表面變形成蛇腹狀。因此，主要圖形101、102中與形成有皺紋的區域重複的部分的視認性降低，而可讓使用者容易認識帶構件30、40。又，藉由形成複數個皺紋，使帶構件30、40看起來更厚，並且，可讓使用者感覺到柔軟性。Further, the main patterns 101 and 102 are repeatedly and at least partially overlapped with the continuous portions of the waist elastic members 35 and 45 (that is, the portions of the waist elastic members 35 and 45) subjected to the reverse operation. Configuration. In the continuous portion, the waist elastic members 35 and 45 are contracted, and the belt members 35 and 45 are contracted in the left-right direction to form a plurality of wrinkles having irregularities in the thickness direction. That is, the surfaces of the belt members 30, 40 are deformed into a bellows shape. Therefore, the visibility of the portion of the main patterns 101 and 102 that overlaps with the wrinkle-forming region is lowered, and the tape members 30 and 40 can be easily recognized by the user. Further, by forming a plurality of wrinkles, the belt members 30, 40 are made thicker, and the user can feel softness.

又，在紙尿褲1，接合吸收性本體10與前側帶構件30的前側本體接合部51，是在由圖5A的斜線部所示的位置，沿著上下方向的帶狀的帶狀接合部51a藉由在左右方向分開預定的間隔複數排列而被形成。而且，該前側本體接合部51與前側主要圖形101在至少一部分的區域重複。在紙尿褲1穿用時，若前側帶構件30(腰圍彈性構件35)在左右方向收縮，吸收性本體10中形成有帶狀接合部51a的部分與前側帶構件30一起朝左右方向收縮。另一方面，在左右方向相鄰的2個帶狀接合部51a之間，吸收性本體10在左右方向不會收縮，前側帶構件30與吸收性本體10互相剝離地容易朝厚度方向浮起。而且，在該浮起的區域，前側主要圖形101的視認性大幅下降。藉此，更容易認識前側帶構件30的厚度。Further, in the diaper 1, the front side main body joint portion 51 that joins the absorbent main body 10 and the front side belt member 30 is borrowed from the strip-shaped joint portion 51a in the vertical direction at a position indicated by a hatched portion in Fig. 5A. It is formed by a plurality of predetermined intervals spaced apart in the left-right direction. Moreover, the front side body joint portion 51 overlaps with the front side main pattern 101 in at least a portion of the area. When the diaper 1 is worn, if the front side belt member 30 (waist elastic member 35) is contracted in the left-right direction, the portion in which the belt-shaped joint portion 51a is formed in the absorbent body 10 is contracted in the left-right direction together with the front side belt member 30. On the other hand, between the two belt-shaped joint portions 51a adjacent in the left-right direction, the absorbent body 10 does not shrink in the left-right direction, and the front side belt member 30 and the absorbent body 10 are easily separated from each other in the thickness direction. Further, in the floating region, the visibility of the front main pattern 101 is greatly lowered. Thereby, it is easier to recognize the thickness of the front side belt member 30.

同樣，接合吸收性本體10與後側帶構件40的後側本體接合部52，是如由圖5B的斜線部所示，沿著上下方向的帶狀的帶狀接合部52a藉由在左右方向分開預定的間隔複數個排列而被形成。而且，後側本體接合部52與後側主要圖形102在至少一部分的區域重複。因此，在左右方向相鄰的2個帶狀接合部52a之間，藉由後側帶構件40與吸收性本體10浮起，更容易認識後側帶構件40的厚度。Similarly, the rear side body joint portion 52 that joins the absorbent body 10 and the rear side belt member 40 is a strip-shaped joint portion 52a along the vertical direction as shown by the oblique line portion of FIG. 5B in the left-right direction. Formed by a plurality of arrangements separated by a predetermined interval. Moreover, the rear side body engaging portion 52 and the rear side main pattern 102 are repeated in at least a portion of the area. Therefore, the thickness of the rear side belt member 40 is more easily recognized by the rear side belt member 40 and the absorbent main body 10 floating between the two belt-shaped joint portions 52a adjacent in the left-right direction.

此外，在紙尿褲1，雖只要在吸收性本體10的前側面(腹側)及後側面(背側)中的至少一方側設有主要圖形即可，尤其，在後側面設有後側主要圖形102為期望。這是讓嬰幼兒穿用紙尿褲1的狀態下，由於視認後側主要圖形102的機會多，後側主要圖形102會對於紙尿褲1的設計性造成很大的影響。例如如圖6，穿用紙尿褲1的嬰幼兒進行爬行時，在覆蓋嬰幼兒的臀部的後側面，後側主要圖形102容易讓使用者(照護者)的眼睛注意，並與所畫的人物角色一起作用產生可愛的印象。Further, in the diaper 1, as long as the main pattern is provided on at least one of the front side (ventral side) and the rear side (back side) of the absorbent body 10, in particular, the back side main pattern is provided on the rear side. 102 is the expectation. In the state in which the infant wears the diaper 1, the rear main pattern 102 greatly affects the design of the diaper 1 because there are many chances of visually recognizing the rear main pattern 102. For example, as shown in Fig. 6, when an infant wearing the diaper 1 is crawling, on the rear side of the buttocks covering the infant, the rear main pattern 102 is easily noticed by the eyes of the user (caregiver) and the personas drawn. A function produces a lovely impression.

而且，如上述，在後側主要圖形102中與後側帶構件40重複的部分(被配置在後側重複部10bu的部分)，和沒有與後側帶構件40重複的部分(被配置在後側不重複部10bd的部分)比較視認性降低。因此，後側帶構件40的厚度一看容易認識，即使穿用者(嬰幼兒)進行爬行這樣的運動時，使用者(照護者)不會對該後側帶構件40的強度感覺到不安，而可安心地觀看。Further, as described above, the portion overlapping the rear side belt member 40 in the rear side main pattern 102 (the portion disposed on the rear side overlapping portion 10bu) and the portion not overlapping the rear side belt member 40 (disposed in the rear) The portion of the side non-repeating portion 10bd has a lower visibility. Therefore, the thickness of the rear side belt member 40 is easy to recognize at a glance, and the user (caregiver) does not feel uncomfortable with the strength of the rear side belt member 40 even when the wearer (infant child) performs the movement such as crawling. And you can watch it with peace of mind.

本實施形態的紙尿褲1，是如圖5A及圖5B所示，設有前側主要圖形101及後側主要圖形102的兩方。而且，在前側主要圖形101與後側主要圖形102，大小、配置不同。首先，若關於前後的主要圖形101、102的配置來說，是以前側主要圖形101的上下方向中的中央位置C101比後側主要圖形102的上下方向中的中央位置C102更高地配置兩者。亦即，在圖5A及圖5B，前側主要圖形101的中央位置C101與折疊位置C10之間的上下方向的距離LC101比後側主要圖形102的中央位置C102與折疊位置C10之間的上下方向的距離LC102更大(LC101＞LC102)。The diaper 1 of the present embodiment is provided with both the front main pattern 101 and the rear main pattern 102 as shown in FIGS. 5A and 5B. Moreover, the size and configuration of the front main pattern 101 and the rear main pattern 102 are different. First, the arrangement of the main patterns 101 and 102 in the front and rear is such that the center position C101 in the vertical direction of the front main pattern 101 is higher than the center position C102 in the vertical direction of the rear main pattern 102. That is, in FIGS. 5A and 5B, the distance LC101 between the center position C101 and the folding position C10 of the front main pattern 101 is higher than the vertical direction between the center position C102 and the folding position C10 of the rear main pattern 102. Larger than LC102 (LC101>LC102).

嬰幼兒穿用紙尿褲1的時候，吸收性本體10的前側的***部(上下方向的下部)因為被兩腿夾著而容易朝寬邊方向(左右方向)收縮。因此，在跨下部附近配置有前側主要圖形101時，因吸收性本體10收縮，前側主要圖形101也朝寬邊方向收縮會有變的不易被視認的顧慮。另一方面，在吸收性本體10的後側這樣的問題不易產生，又，藉由在低的位置設置後側主要圖形102，而在穿用者的臀部的廣大的範圍容易視認。因此，紙尿褲1，是在上下方向將前側主要圖形101配置在比後側主要圖形102更高的位置，藉此，在穿用時，在最適當的狀態視認各個的主要圖形101、102。When the diaper 1 is worn by the infant, the crotch portion (the lower portion in the up-and-down direction) of the front side of the absorbent main body 10 is easily contracted in the widthwise direction (left-right direction) by being sandwiched between the legs. Therefore, when the front main pattern 101 is disposed in the vicinity of the lower portion, the contraction of the absorbent main body 10 causes the front main pattern 101 to contract in the widthwise direction, which may become difficult to be visually recognized. On the other hand, such a problem as the rear side of the absorbent body 10 is less likely to occur, and the rear main pattern 102 is provided at a low position, so that it is easily visible in a wide range of the wearer's buttocks. Therefore, in the diaper 1, the front main pattern 101 is disposed at a position higher than the rear main pattern 102 in the vertical direction, whereby the main patterns 101 and 102 are visually recognized in the most appropriate state when worn.

接著，關於前後的主要圖形101、102的大小，在紙尿褲1以前側主要圖形101的大小(面積)比後側主要圖形102的大小(面積)更小地形成前側主要圖形101。如上述，後側主要圖形102，是配置在嬰幼兒進行爬行的時候容易進到使用者的眼睛的位置。而且，讓與後側帶構件40重複的區域中的視認性降低，而具有讓使用者容易認識後側帶構件40的厚度的機能。因此，藉由盡量大地形成後側主要圖形102，邊提高作為後側主要圖形102整體的視認性，可容易認識在與後側帶構件40重複的部分和沒有重複的部分，在視認性產生差的情況。Next, regarding the sizes of the front and rear main patterns 101 and 102, the front main pattern 101 is formed smaller than the size (area) of the main pattern 101 on the front side of the diaper 1 smaller than the size (area) of the rear main pattern 102. As described above, the rear main pattern 102 is disposed at a position where the infant easily enters the eyes of the user when crawling. Further, the visibility in the region overlapping the rear side belt member 40 is lowered, and the function of allowing the user to easily recognize the thickness of the rear side belt member 40 is provided. Therefore, by forming the rear main pattern 102 as much as possible, the visibility as the entire back main pattern 102 is improved, and the portion overlapping with the rear side belt member 40 and the portion not overlapping can be easily recognized, and the visibility is poor. Case.

又，在本實施形態的紙尿褲1，前側主要圖形101與前側帶構件30重複的部分的面積比後側主要圖形102與後側帶構件40重複的部分的面積更小(參照圖5A、圖5B)。前側主要圖形101由於被配置在嬰幼兒進行爬行時，使用者不易視認的位置，所以，與後側主要圖形102比較，不易知道與前側帶構件30重複所致的視認性的降低。另一方面，後側主要圖形102，是如上述由於是嬰幼兒進行爬行時使用者眼睛容易看到的，所以，與後側帶構件40的重複部分愈大，該重複部分中的後側主要圖形102的視認性的降低程度容易變的顯眼。Further, in the diaper 1 of the present embodiment, the area of the portion where the front side main pattern 101 and the front side belt member 30 overlap is smaller than the area of the portion where the rear side main pattern 102 and the rear side belt member 40 overlap (see FIGS. 5A and 5B). ). Since the front main pattern 101 is disposed at a position that is difficult for the user to visually recognize when the infant is crawling, it is difficult to know the deterioration of the visibility due to the repetition of the front side belt member 30 as compared with the rear main pattern 102. On the other hand, the rear main pattern 102 is as easily seen by the user's eyes when the infant is crawling as described above, so that the larger the overlapping portion with the rear side belt member 40, the rear side of the repeating portion is mainly The degree of reduction in the visibility of the graphic 102 is apt to become conspicuous.

又，在紙尿褲1，主要圖形101、102的輪廓線的粗度(寬度)在預定值(例如3mm)以上為期望。在本實施形態，讓主要圖形101、102的一部分的區域與帶構件30、40重複，藉此，讓該區域中的視認性刻意降低。因此，若輪廓線太細，會有不能認識主要圖形的圖案的形狀的顧慮。而相對於此，輪廓線若由3mm以上的粗度所形成，則透過被層積在主要圖形101、102之上的複數個不織布(15b；31、32；41、42等)，邊認識主要圖形101、102的形狀，邊容易知道視認性降低的情況。此外，「輪廓線」，是指相對於背景(於此作為被印刷媒體的防漏薄片15a)形成圖形的外形的線的情況。圖形由全面塗抹所形成時(例如，圖5A的熊貓的耳朵的部分等)，可考慮包含該圖形的外緣的全面塗抹部分整體為輪廓線即可。Further, in the diaper 1, it is desirable that the outline (width) of the outlines of the main patterns 101 and 102 is equal to or greater than a predetermined value (for example, 3 mm). In the present embodiment, the area of a part of the main patterns 101 and 102 is overlapped with the belt members 30 and 40, whereby the visibility in the area is intentionally lowered. Therefore, if the outline is too thin, there is a concern that the shape of the pattern of the main pattern cannot be recognized. On the other hand, if the outline is formed by a thickness of 3 mm or more, a plurality of non-woven fabrics (15b; 31, 32; 41, 42, etc.) stacked on the main patterns 101 and 102 are transmitted through the main body. It is easy to know that the visibility of the patterns 101 and 102 is lowered. In addition, the "contour line" refers to a line of a shape in which a figure is formed with respect to a background (here, a leakage preventing sheet 15a as a medium to be printed). When the pattern is formed by the full application (for example, the portion of the panda's ear of Fig. 5A, etc.), it is conceivable that the entire application portion including the outer edge of the pattern is an outline.

又，在紙尿褲1，在吸收性本體10形成主要圖形101、102時，藉由依據吸收性本體10(防漏薄片15a)的區域變更印刷條件，使該主要圖形101、102的一部分的區域中的視認性降低的程度變明確。Further, in the diaper 1, when the main patterns 101 and 102 are formed in the absorbent main body 10, the printing conditions are changed in accordance with the area of the absorbent main body 10 (the leakage preventing sheet 15a) so that a part of the main patterns 101 and 102 are in the area. The degree of reduction in visibility is clear.

例如，形成後側主要圖形102時，在後側重複部10bu與後側不重複部10bd將印刷色調值調整成同等的大小，而可進行印刷。具體而言，被形成在與後側帶構件40重複的區域(後側重複部10bu)的後側主要圖形102的印刷色調值的平均、與被形成在與後側帶構件40不重複的區域(後側不重複部10bd)的後側主要圖形102的印刷色調值的平均，是以大致成為同等地進行印刷。其結果，後側主要圖形102中，與後側帶構件40重複的部分中的濃度、和不重複的部分的濃度被印刷成幾乎同等的圖像。從外側觀看這樣的紙尿褲1時，在與後側帶構件40重複的部分(後側重複部10bu)，藉由在後側主要圖形102之上層積複數個不織布(15b、41、42)，使該後側主要圖形102的濃度比實際被印刷的圖像看起來淡。另一方面，在與後側帶構件40沒有重複的部分(後側不重複部10bd)，因為被從層積在後側主要圖形102之上的不織布的片數少，所以，後側主要圖形102看來且與實際被印刷的圖像同等的濃度。因此，使用者從外側視認紙尿褲1時，在後側重複部10bu與後側不重複部10bd，圖像的濃度的差變的顯著，在後側重複部10bu，後側主要圖形102的視認性降低的情況變的明確。關於前側主要圖形101也同樣。For example, when the rear main pattern 102 is formed, the printing color value can be adjusted to the same size in the rear side repeating portion 10bu and the rear side non-repeat portion 10bd, and printing can be performed. Specifically, the average of the printed tone values of the rear main pattern 102 formed in the region overlapping with the rear side belt member 40 (the rear side overlapping portion 10bu) and the region formed in the rear side belt member 40 are not overlapped. The average of the printed tone values of the rear main pattern 102 (the rear side non-repeating portion 10bd) is printed substantially equally. As a result, in the rear main pattern 102, the density in the portion overlapping the rear side belt member 40 and the density of the non-overlapping portion are printed in almost the same image. When such a diaper 1 is viewed from the outside, a plurality of non-woven fabrics (15b, 41, 42) are laminated on the rear main pattern 102 at a portion overlapping with the rear side belt member 40 (back side repeating portion 10bu). The concentration of the rear side main pattern 102 is lighter than the image actually printed. On the other hand, in the portion which is not overlapped with the rear side belt member 40 (the rear side non-repeating portion 10bd), since the number of non-woven fabrics which are laminated from the rear side main pattern 102 is small, the rear main pattern is 102 appears to be the same concentration as the actual printed image. Therefore, when the user views the diaper 1 from the outside, the difference between the density of the image becomes remarkable in the rear side overlapping portion 10bu and the rear side non-repeat portion 10bd, and the rear side main portion 102 is visible in the rear side overlapping portion 10bu. The situation of reduction becomes clear. The same applies to the front main pattern 101.

同樣，形成後側主要圖形102時，也可在後側重複部10bu與後側不重複部10bd使亮度幾乎成為同等。例如，關於印刷後側主要圖形102用的印刷數據，是使被形成在後側重複部10bu的部分的亮度、與被形成在後側不重複部10bd的部分的亮度成為同等地進行調整，來執行印刷。若如此，在後側主要圖形102中與後側帶構件40重複的部分(後側重複部10bu)、以及不重複的部分(後側不重複部10bd)印刷具有同程度的亮度的圖像。此時，在後側重複部10bu藉由透過複數個不織布看見，而使後側主要圖形102比實際被印刷的圖像看起來更暗，在後側不重複部10bd，使後側主要圖形102看起來與實際被印刷的圖像同等的亮度。因此，使用者從外側視認紙尿褲1時，在後側重複部10bu與後側不重複部10bd，圖像的亮度的差變的顯著，在後側重複部10bu，後側主要圖形102的視認性降低的情況變的明確。關於前側主要圖形101也同樣。Similarly, when the rear main pattern 102 is formed, the brightness of the rear side repeating portion 10bu and the rear side non-repeat portion 10bd can be made almost equal. For example, the print data for the post-printing main pattern 102 is adjusted such that the brightness of the portion formed on the rear side repeating portion 10bu is equal to the brightness of the portion formed on the rear side non-overlapping portion 10bd. Perform printing. In this manner, an image having the same degree of brightness is printed on the portion of the rear main pattern 102 that overlaps with the rear side belt member 40 (the rear side repeating portion 10bu) and the non-overlapping portion (the rear side non-repeating portion 10bd). At this time, the rear side main portion 102 is seen to be darker than the actually printed image by the plurality of non-woven fabrics, and the rear side main pattern 102 is not overlapped on the rear side. It looks the same brightness as the actual printed image. Therefore, when the user views the diaper 1 from the outside, the difference between the brightness of the image becomes remarkable in the rear side overlapping portion 10bu and the rear side non-repeat portion 10bd, and the rear side main portion 102 is visible in the rear side overlapping portion 10bu. The situation of reduction becomes clear. The same applies to the front main pattern 101.

又，在紙尿褲1，藉由調整吸收性本體10中與前側帶構件30及後側帶構件40分別重複的部分的大小，提高設計性。圖7的例子，是將吸收性本體10的後側上端10eb的上下方向中的高度配置在比前側上端10ea的上下方向中的高度更高的位置。亦即，在上下方向，藉由吸收性本體10的前側上端10ea與折疊位置C10之間的距離比後側上端10eb與折疊位置C10之間的距離更大，使吸收性本體10的後側面的面積比前側面的面積更大。若如此，在後側面可取得大的可印刷的區域，而可更自由地容易形成後側主要圖形102。藉此，可提高作為紙尿褲1整體的設計性。Moreover, in the diaper 1, the designability is improved by adjusting the size of the portion of the absorbent body 10 that overlaps with the front side belt member 30 and the rear side belt member 40, respectively. In the example of FIG. 7 , the height in the up-and-down direction of the rear upper end 10eb of the absorbent body 10 is disposed at a position higher than the height in the vertical direction of the front upper end 10ea. That is, in the up and down direction, the distance between the front upper end 10ea of the absorbent body 10 and the folded position C10 is larger than the distance between the rear upper end 10eb and the folded position C10, so that the rear side of the absorbent body 10 is The area is larger than the area on the front side. If so, a large printable area can be obtained on the rear side, and the rear side main pattern 102 can be formed more freely. Thereby, the design as the entire diaper 1 can be improved.

又，與圖7的情況相反，吸收性本體10的後側上端10eb的上下方向中的高度與前側上端10ea的上下方向中的高度相同、或也可配置在與前側上端10ea的上下方向中的高度配置在更低的位置。此時，吸收性本體10的前側面的面積變大，前側面中的可印刷區域變大。前側面的胯間側(上下方向的下側)的區域，是紙尿褲1的穿用時被戴用者的兩腿夾者，而使圖形變得不易視認。因此，在吸收性本體10的前側面，在腰圍開口側(上下方向的上側)寬廣設置可形成前側主要圖形101的區域，在紙尿褲1的穿用時抑制前側主要圖形101的視認性惡化的情況，可提高紙尿褲1的設計性。Further, contrary to the case of FIG. 7, the height in the up-and-down direction of the rear upper end 10eb of the absorbent body 10 is the same as the height in the up-and-down direction of the front upper end 10ea, or may be disposed in the up-and-down direction with the front upper end 10ea. The height is configured at a lower position. At this time, the area of the front side surface of the absorbent body 10 becomes large, and the printable area in the front side surface becomes large. The area of the crotch side (the lower side in the up-and-down direction) of the front side is the leg of the wearer when the diaper 1 is worn, and the figure is difficult to visualize. Therefore, on the front side surface of the absorbent body 10, a region where the front main pattern 101 can be formed is widely provided on the waist opening side (upper side in the vertical direction), and the visibility of the front main pattern 101 is suppressed from being deteriorated when the diaper 1 is worn. The design of the diaper 1 can be improved.

又，如圖7所示，被設在吸收性本體10的前側面的指示部60的長度比被設在吸收性本體10的後側面的指示部60的長度更長。在紙尿褲1，因為後側主要圖形102容易比前側主要圖形101被形成的更大，所以，在後側面若長長地配置指示部60，則後側主要圖形102與指示部60的重複部分容易變大。此時，在紙尿褲1的穿用時進行排尿，若指示部60的顏色進行變化，則在與該指示部60重複的部分，會有後側主要圖形102的視認性惡化的顧慮。尤其，如圖6，穿用者(嬰幼兒)進行爬行的時候，因指示部60的原因的視認性惡化容易變的顯眼，會有所謂損毀讓使用者認識後側帶構件40的厚度的後側主要圖形102的機能的顧慮。亦即，會有後側主要圖形102的視認性不必要地惡化的情況。於此，在紙尿褲1，是吸收性本體10的後側面中的指示部60的長度變的比後側面中的指示部60的長度更短。藉此，後側主要圖形102與指示部60不易重複，所以，可抑制後側主要圖形102的視認性不必要的惡化情況。Further, as shown in FIG. 7, the length of the indication portion 60 provided on the front side surface of the absorbent body 10 is longer than the length of the indication portion 60 provided on the rear side surface of the absorbent body 10. In the diaper 1, since the rear main pattern 102 is more likely to be formed than the front main pattern 101, if the indication portion 60 is disposed long on the rear side, the rear main pattern 102 and the overlapping portion of the indication portion 60 are easy. Become bigger. At this time, urination is performed when the diaper 1 is worn, and when the color of the indication portion 60 is changed, the visibility of the rear main pattern 102 may be deteriorated in the portion overlapping the instruction portion 60. In particular, as shown in Fig. 6, when the wearer (infant child) is crawling, the deterioration of the visibility due to the instruction unit 60 is likely to become conspicuous, and the user may recognize the thickness of the rear side belt member 40. The function of the side main graphic 102 is a concern. That is, there is a case where the visibility of the rear main pattern 102 is unnecessarily deteriorated. Here, in the diaper 1, the length of the indication portion 60 in the rear side surface of the absorbent body 10 becomes shorter than the length of the indication portion 60 in the rear side surface. Thereby, since the rear main pattern 102 and the indication portion 60 are not easily overlapped, it is possible to suppress unnecessary deterioration of the visibility of the rear main pattern 102.

而且，在紙尿褲1，前側主要圖形101與指示部60的重複部分的面積比後側主要圖形102與指示部60的重複部分的面積更大。如上述，若後側主要圖形102與指示部60的重複區域變大，則不需要的視認性的惡化變的容易顯眼。另一方面，前側主要圖形101在紙尿褲1的穿用時，藉由被穿用者的兩腿夾入而容易朝左右方向收縮，又，前側主要圖形101，是被配置在嬰幼兒進行爬行時，使用者不易視認的位置。因此，與後側主要圖形102比較，視認性的惡化造成的影響小。亦即，即使前側主要圖形101與指示部60的重複區域變大，問題也不易產生。根據這樣的結構，使用者在與帶構件30、40重複的區域和不重複的區域可容易認識主要圖形101、102的視認性的差。因此，依據該主要圖形101、102的視認性的差，可讓使用者認識帶構件30、40的厚度。Further, in the diaper 1, the area of the overlapping portion of the front side main pattern 101 and the indication portion 60 is larger than the area of the rear side main pattern 102 and the overlapping portion of the indication portion 60. As described above, when the overlapping area of the rear main pattern 102 and the indication portion 60 is increased, the deterioration of unnecessary visibility becomes conspicuous. On the other hand, when the diaper 1 is worn, the front main pattern 101 is easily folded in the left-right direction by being sandwiched by the wearer's legs, and the front main pattern 101 is disposed when the infant is crawling. , the location that the user is not easy to see. Therefore, compared with the rear main pattern 102, the influence of the deterioration of visibility is small. That is, even if the overlapping area of the front main pattern 101 and the indication portion 60 becomes large, the problem is less likely to occur. According to such a configuration, the user can easily recognize the difference in visibility of the main patterns 101 and 102 in the area overlapping the belt members 30 and 40 and the non-overlapping area. Therefore, the thickness of the belt members 30 and 40 can be recognized by the user based on the difference in visibility of the main patterns 101 and 102.

此外，僅在吸收性本體10的前側面設置指示部60，而在後側面不設置亦可。若如此，可將指示部60與後側主要圖形102的重複部分的面積做成最小，因排尿使指示部60的顏色產生變化時，容易抑制後側主要圖形102的不要的視認性的惡化。Further, the indication portion 60 may be provided only on the front side surface of the absorbent body 10, and may not be provided on the rear side surface. In this manner, the area of the overlapping portion of the indication portion 60 and the rear main pattern 102 can be minimized, and when the color of the indication portion 60 is changed by urination, it is easy to suppress the deterioration of the unnecessary visibility of the rear main pattern 102.

再者，也可以後側主要圖形102與指示部60不重複地配置指示部60。若後側主要圖形102與指示部60沒有重複，即使因排尿使指示部60的顏色產生變化時，因為對後側主要圖形102的視認性不易產生影響，所以，進一步容易抑制後側主要圖形102的不要的視認性的惡化。Furthermore, the indication unit 60 may be disposed without repeating the rear main pattern 102 and the indication unit 60. When the rear main pattern 102 and the indication portion 60 are not overlapped, even if the color of the indication portion 60 is changed due to urination, since the visibility of the rear main pattern 102 is less likely to be affected, it is easier to suppress the rear main pattern 102. Do not deteriorate the visibility.
