[0003] [Patent Document 1] JP 2019-180486 A Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, light incontinence pants and shorts-type napkins have been attracting attention as pants-type absorbent articles that can be worn like underwear. Of these, light incontinence pants are "urinary care products," and therefore tend to cause psychological resistance in users compared to shorts-type napkins, which are "sanitary products" used by users of a wide range of ages. For example, if a third party sees that a user is using light incontinence pants while traveling or going out, this may hurt the user's self-esteem or cause embarrassment. For these reasons, there is an increasing demand to not let others know the type of pants-type absorbent article (light incontinence pants, etc.) that the user is using.

[0005] The present invention aims to make it difficult to tell the type of each product from the outside in pants-type (shorts-type) absorbent articles. [Means for solving the problem]

[0006] The main idea for achieving the above object is light incontinence pants having a first waistline member having a top-bottom direction, a left-right direction, and a front-rear direction that intersect with each other, the first absorbent body, and a first front waistline portion and a first rear waistline portion joined to each other by a pair of first side joints provided at both ends in the left-right direction, the length of the first waistline member in the left-right direction in a stretched state, the length of the first side joints in the up-down direction in a stretched state, and the manner in which the light incontinence pants are folded in a packaged state are determined by a second absorbent body, and a second front waistline portion and a second rear waistline portion are joined to each other by a pair of first side joints provided at both ends in the left-right direction. The light incontinence pants are characterized in that a shorts-type napkin has a second waist member joined to each other by a pair of second side joints, the left-right length of the second waist member in an extended state, the up-down length of the second side joints in an extended state, and the way in which the shorts-type napkin is folded in a packaged state are all the same, and the package of the light incontinence pants is marked with the same sales company name as the sales company name marked on the package of the shorts-type napkin, and is marked with a product name different from the product name marked on the package of the shorts-type napkin. Other features of the present invention will become apparent from the following detailed description and accompanying drawings. Effect of the Invention

[0009] At least the following points will become apparent from the description of this specification and the accompanying drawings. Light incontinence pants comprising a first waist member having a top-bottom direction, a left-right direction, and a front-rear direction that intersect with each other, and a first absorbent main body, and a first waist member in which a first front waist portion and a first rear waist portion are joined to each other by a pair of first side joints provided at both ends in the left-right direction, wherein the length in the left-right direction of the first waist member in an extended state, the length in the up-down direction of the first side joints in an extended state, and the manner in which the light incontinence pants are folded in a packaged state are determined by a second absorbent main body, and a pair of second side joints in which a second front waist portion and a second rear waist portion are joined to each other by a pair of second side joints provided at both ends in the left-right direction. Light incontinence pants characterized in that a shorts-type napkin has a second waist member joined to each other by a joint, the left-right length of the second waist member in an extended state, the up-down length of the second side joint in an extended state, and the way in which the shorts-type napkin is folded in a packaged state are all the same, and the package of the light incontinence pants is marked with the same sales company name as the sales company name marked on the package of the shorts-type napkin, and is marked with a product name different from the product name marked on the package of the shorts-type napkin.

[0010] With such light incontinence pants, the light incontinence pants and the shorts-type napkin have almost the same external appearance, making it difficult for third parties to notice the type of pants-type absorbent article being used. Also, by checking the product name on the package, users can purchase and use the correct type of pants-type absorbent article. This can reduce the psychological resistance of users who want to use a urinary care product but do not want third parties to know about it.

[0011] In the light incontinence pants, the design of the individual packaging of the light incontinence pants in which the light incontinence pants in a folded state are individually packaged in a first packaging material is as follows: It is desirable that the shorts-type napkins in the folded state have a design similar to that of the individual packages of shorts-type napkins individually wrapped in a second wrapping material.

[0012] With such light incontinence pants, when individually packaged, the individual packaging of the light incontinence pants and the individual packaging of the shorts-type napkin have the same design, making it difficult for a third party to distinguish between the two in appearance, thereby making it difficult for a third party to know the type of pants-type absorbent article that the user is using.

[0013] In such light incontinence pants, it is desirable that the design of the package for the light incontinence pants is different from the design of the package for the shorts-type napkin.

[0014] With such light incontinence pants, even if the individual packaging of the light incontinence pants and the individual packaging of the shorts-type napkin have the same design, the user can distinguish between them by checking the package design (marking). Therefore, the user can use the individually packaged pants-type absorbent article without making a mistake in the type.

[0015] In such light incontinence pants, it is desirable that the design of the individual package of the light incontinence pants in which the light incontinence pants in a folded state are individually packaged in a first packaging material is different from the design of the individual package of the shorts-type napkin in which the shorts-type napkin in a folded state is individually packaged in a second packaging material.

[0016] With such light incontinence pants, in cases where the individually packaged pants-type absorbent article is unlikely to be seen by a third party, the different designs of the individual packages of the light incontinence pants and the individual packages of the shorts-type napkin allow the user to use the pants-type absorbent article without making a mistake.

[0017] In such light incontinence pants, it is desirable that the design of the package for the light incontinence pants is different from the design of the package for the shorts-type napkin.

[0018] With such light incontinence pants, the individual packaging of the light incontinence pants and the individual packaging of the shorts-type napkin have different designs, and the user can easily distinguish between the two by checking the package design (marking). Therefore, the user is less likely to mistake the type of individually packaged pants-type absorbent article.

[0019] In such light incontinence pants, in an individual package of light incontinence pants in which the light incontinence pants in a folded state are individually packaged in a first packaging material, it is desirable that the design of the light incontinence pants visible when viewed through the outside of the first packaging material is similar to the design of the shorts-type napkin visible when viewed through the outside of the second packaging material in an individual package of shorts-type napkin in which the shorts-type napkin in a folded state is individually packaged in a second packaging material.

[0020] According to such light incontinence pants, when a user takes out the individual package from a bag or the like to use the light incontinence pants while out and about, the first package may be exposed to light from the outside to the inside depending on the amount of light, etc. Even if your body (light incontinence pants) are visible to third parties, If the design is the same as when seen through the individual packaging of the sanitary napkin, it will not be visible to a third party. Even if the type of pants-type absorbent article is changed, it is difficult to tell from the outside what type the pants-type absorbent article is.

[0021] In the light incontinence pants, the light incontinence pants in a folded state are wrapped in a first packaging material. In the individual package of the light incontinence pants individually packaged by the first packaging material, The design of the light incontinence pants that is visible when viewed through the side is folded The short-type napkin in the state is individually wrapped in a second wrapping material. In the individual packaging of the kin, the above-mentioned is visible when seen through the outside of the second packaging material. It is desirable that the design be different from that of shorts-type napkins.

[0022] According to such light incontinence pants, the user can see through the individual package from the outside and into the light. This makes it easier to identify the type of pants-type absorbent product inside. With just a quick glance, the type of panty-type absorbent article inside the package can be accurately identified. Therefore, it is difficult for a third party to know the type of pants-type absorbent article. This makes it easier for users to identify them themselves.

[0023] In such light incontinence pants, the first waistband member is provided with a surface closest to the skin. The sheet member is the same as the sheet member constituting the surface closest to the skin of the second waistband member. It is desirable for the sheet member to be a sheet member.

[0024] According to such light incontinence pants, the light incontinence pants and the shorts-type napkin are By using similar sheet members to configure the respective exteriors, it becomes difficult to distinguish between the first waistline member and the second waistline member, and it becomes difficult for a third party to visually identify each of the pants-type absorbent articles. Therefore, it is possible to make it difficult to distinguish the types of pants-type absorbent articles from the outside.

[0025] In such light incontinence pants, it is desirable that the sheet material constituting the surface of the first waist member closest to the skin be a different sheet material from the sheet material constituting the surface of the second waist member closest to the skin.

[0026] With such light incontinence pants, the user can easily distinguish between the two due to the difference in texture, such as the feel of the waistband member. On the other hand, it is difficult for a third party to recognize the difference in the materials between the two just by looking. Therefore, it is possible to make it difficult for a third party to tell the type of pants-type absorbent article, while making it easy for the user to distinguish them.

[0027] In such light incontinence pants, it is desirable that the design of the surface of the first waistband member closest to the skin is different from the design of the surface of the second waistband member closest to the skin.

[0028] According to such light incontinence pants, in normal use, the skin side of the waist member is a part that is visible only to the user (user) and is difficult to be seen by third parties. Therefore, by making the design of the skin side of the waist member different between the light incontinence pants and the shorts-type napkin, it is possible to make it easy for the user to distinguish between the types of pants-type absorbent articles and difficult for third parties to distinguish between the two.

[0029] In such light incontinence pants, it is desirable that the design of the surface of the first absorbent main body closest to the skin is different from the design of the surface of the second absorbent main body closest to the skin.

[0030] According to such light incontinence pants, in normal use, the skin side of the absorbent main body is the part that is visible only to the user (user) and is difficult to be seen by third parties. Therefore, by making the design of the skin side of the absorbent main body different between the light incontinence pants and the shorts-type napkin, it is possible to make it easy for the user to distinguish between the types of pants-type absorbent articles and difficult for third parties to distinguish between the two.

[0031] In such light incontinence pants, it is desirable that the thickness of the first absorbent main body in its natural state is different from the thickness of the second absorbent main body in its natural state.

[0032] With such light incontinence pants, the difference in thickness of the absorbent main body is difficult for a third party to see from the outside, whereas the user can easily recognize the difference between the two by touch. Therefore, by making the thickness of the absorbent main body different between the light incontinence pants and the shorts-type napkin, it is possible for the user to easily distinguish between the types of pants-type absorbent articles, while making it difficult for a third party to distinguish between the two.

[0033] In such light incontinence pants, it is desirable that the number of the light incontinence pants contained in the package of the light incontinence pants in an unopened state is different from the number of the shorts-type napkins contained in the package of the unopened shorts-type napkins.

[0034] With such light incontinence pants, if the number of light incontinence pants and shorts-type napkins contained in a package differs, it is difficult for a third party who does not intend to purchase the product at a store or the like to distinguish the type of pant-type absorbent article just by visually inspecting them. On the other hand, a user who intends to purchase the product can easily distinguish between the two based on the difference in the number of items contained. Therefore, it is easy for the user to distinguish between the types of pant-type absorbent articles, and it is possible to make it difficult for a third party to distinguish between the two.

[0035] In such light incontinence pants, it is desirable that the light incontinence pants and the shorts-type napkin each have leg openings, and that the shape of the outer edge of the leg openings of the light incontinence pants in a stretched state and the length along the outer edge of the leg openings of the light incontinence pants in a stretched state are different from the shape of the outer edge of the leg openings of the shorts-type napkin in a stretched state and the length along the outer edge of the leg openings.

[0036] According to such light incontinence pants, if the length or shape of the outer edges of the leg openings of the light incontinence pants and the shorts-type napkin are different, it is difficult for a third party to tell the difference between the two just by looking, whereas a user can easily tell that the size and shape of the leg openings are different when the user opens them during the putting on action. Therefore, it is easy for the user to distinguish between the types of pants-type absorbent articles, while making it difficult for a third party to distinguish between the two.

[0037] In such light incontinence pants, it is desirable that the second absorbent body is provided with a second linear compression portion in which compression portions that compress the second absorbent body in the thickness direction are arranged in a line, and that the first absorbent body is not provided with a first linear compression portion corresponding to the second linear compression portion, the first linear compression portion being a first linear compression portion in which compression portions that compress the first absorbent body in the thickness direction are arranged in a line.

[0038] According to such light incontinence pants, the shorts-type napkin, which is a sanitary product, is provided with a second linear compressed portion, which allows the second absorbent body to bend and deform easily, making it easier to fit to the user's crotch when worn. On the other hand, light incontinence pants, which are urinary care products, desirably have some gap between them and the user's body, and there is no need to provide linear compressed portions to make them easier to deform. Furthermore, the linear compressed portions provided on the absorbent body are visible only to the user, and are difficult to see by third parties. This improves the functionality of each pant-type absorbent article, while making it easier for the user to distinguish between the types of pant-type absorbent article, and making it easier for third parties to distinguish between the two. This makes it difficult for the user to identify the person.

[0039] In the light incontinence pants, the second absorbent body is provided with the shorts-type The second absorbent body elastic member is provided to stretch along the longitudinal direction of the napkin, and the first absorbent body elastic member is provided to stretch along the longitudinal direction of the napkin. The elastic body includes a first absorbent body elastic member corresponding to the second absorbent body elastic member in a deployed state. The light incontinence pants are not provided with a first absorbent body elastic member that stretches along the longitudinal direction of the pants. , it is desirable.

[0040] According to such light incontinence pants, the shorts-type sanitary napkin is a secondary absorbent. The second absorbent body is pressed against the crotch area of ​​the user by the elasticity of the body elastic member. On the other hand, incontinence pants, which are urinary care products, do not have the elasticity of the absorbent elastic material. Therefore, gaps are easily formed between the first absorbent body and the user's skin. The absorbent body elastic member provided on the absorbent body is easily visible to the user, but is not visible to third parties. This improves the functionality of each pants-type absorbent article while allowing the user to This makes it easy to distinguish the type of absorbent article, while making it difficult for a third party to distinguish between the two.

[0041] In the light incontinence pants, the first absorbent body is provided with the light incontinence pants in an expanded state. The first absorbent body elastic member is provided to stretch along the longitudinal direction of the absorbent body. The body is provided with a second absorbent elastic portion that stretches along the longitudinal direction of the shorts-type napkin in the developed state. The elastic member of the first absorbent body is stretched by a unit length along the longitudinal direction. The magnitude of the force acting when the second absorbent body elastic member is moved in the longitudinal direction is It is preferable that the magnitude of the force acting when the member is elongated by the same amount is different from that of the force acting when the member is elongated by the same amount.

[0042] According to such light incontinence pants, by adjusting the stress of the absorbent elastic member, when worn, the first absorbent main body of the light incontinence pants is more likely to form a gap between the user's skin and the second absorbent main body of the shorts-type napkin, making it easier to fit around the user's crotch area. Furthermore, such a difference in the stress of the absorbent elastic member is noticeable by the user who actually wears the pants, but not noticeable to third parties. Therefore, it is easy for the user to distinguish between the types of pants-type absorbent articles, and it is difficult for third parties to distinguish between the two.

[0043] In such light incontinence pants, it is desirable that the joining pattern of the first side joining portion is different from the joining pattern of the second side joining portion.

[0044] According to such light incontinence pants, the difference in the joining patterns of the side joint parts is easy for a user who can see it from close up to distinguish, but difficult for a third party to distinguish. Therefore, the difference in the joining patterns of the side joint parts makes it easy for a user to distinguish between the types of pants-type absorbent articles, while making it difficult for a third party to distinguish between the two.

[0045] In such light incontinence pants, it is desirable that the joining pattern of the first side joining portion is the same as the joining pattern of the second side joining portion.

[0046] With such light incontinence pants, the external shapes of the light incontinence pants and the shorts-type napkin become more similar, making it more difficult for a third party to tell the difference between the two.

[0047] In such light incontinence pants, it is desirable that the first rear waist portion is provided with a post-processing tape for maintaining the light incontinence pants in a compact form when the light incontinence pants are disposed of after use, and that when the light incontinence pants are folded, the post-processing tape is not visible from the outside.

[0048] According to such light incontinence pants, the post-cleaning tape is provided, which is used when disposing of the light incontinence pants after use, and can prevent excrement adhering to the absorbent body from leaking out. In addition, since the post-cleaning tape cannot be seen from the outside when the pants are folded, it is difficult for a third party to distinguish between the light incontinence pants and the shorts-type napkin.

[0049] In such light incontinence pants, it is desirable that the brand name displayed on the package of the light incontinence pants is the same as the brand name displayed on the package of the shorts-type napkin.

[0050] According to such light incontinence pants, the same brand name is attached to the packages of the light incontinence pants, which are a urinary care product, and the shorts-type napkin, which is a sanitary product, so it is difficult for a third party to know the type of pants-type absorbent article that the user is about to purchase at a store, etc. This reduces the psychological burden on the user.

[0051] Also, there is a shorts-type napkin having a top-bottom direction, a left-right direction, and a front-rear direction that intersect with each other, and comprising a second absorbent main body and a second waistline member in which a second front waistline portion and a second rear waistline portion are joined to each other by a pair of second side joining portions provided at both ends in the left-right direction, wherein the left-right length of the second waistline member in an extended state, the up-down length of the second side joining portion in an extended state, and the manner in which the shorts-type napkin is folded in a packaged state are determined by determining whether the first front waistline portion and the first rear waistline portion are joined to each other by a pair of first side joining portions provided at both ends in the left-right direction. A shorts-type napkin is disclosed, characterized in that the left-right length of the first waist member in a stretched state, the up-down length of the first side joint portion in a stretched state, and the way the light incontinence pants are folded in a packaged state are all the same as those of light incontinence pants having a first waist member joined to each other by a portion, and the package of the shorts-type napkin is marked with the same sales company name as the sales company name on the package of the light incontinence pants and is marked with a product name different from the product name on the package of the light incontinence pants.

[0052] According to such a shorts-type napkin, the appearance of each product is almost the same for the shorts-type napkin and the light incontinence pants, so that it is difficult for a third party to notice the type of pants-type absorbent article being used. Also, by checking the product name on the package, the user can purchase and use the correct type of pants-type absorbent article. Therefore, it is possible to reduce the psychological resistance of the user in cases where the user wants to use a sanitary product but does not want a third party to know about it.

[0053] Also, a pants-type absorbent article is provided, comprising: a light incontinence pants manufacturing process for manufacturing, by a specified manufacturing line, light incontinence pants comprising a first absorbent main body and a first waistline member in which a first front waistline portion and a first rear waistline portion are joined to each other by a pair of first side joining portions provided at both ends in the left-right direction; a setup change process for changing the setup of the manufacturing line; and a shorts-type napkin manufacturing process for manufacturing, by the specified manufacturing line, shorts-type napkins comprising a second absorbent main body and a second waistline member in which a second front waistline portion and a second rear waistline portion are joined to each other by a pair of second side joining portions provided at both ends in the left-right direction. A method for manufacturing an article, comprising: in the setup change step, the setup is changed so that the left-right length of the first waistline member in an extended state, the up-down length of the first side joint portion in an extended state, and the folding manner of the light incontinence pants in a packaged state are the same as the left-right length of the second waistline member in an extended state, the up-down length of the second side joint portion in an extended state, and the folding manner of the shorts-type napkin in a packaged state, and the basis weight of the superabsorbent polymer in the first absorbent main body is different from the basis weight of the superabsorbent polymer in the second absorbent main body. Thus, a method for manufacturing pants-type absorbent articles, characterized in that the pants-type absorbent articles are replaced with new ones, is disclosed.

[0054] According to this method for manufacturing pants-type absorbent articles, shorts-type napkins and pants for light incontinence are manufactured. By using the same material, it is possible to manufacture pants-type absorbent articles in which the appearance of each product is almost the same. Therefore, it is not possible for a third party to determine the type of napkin, whether it is a shorts-type napkin or light incontinence pants. It is possible to provide a pants-type absorbent article in which the presence or absence of the absorbent material is difficult to discern.

[0055] === Implementation form === As an example of a pants-type (shorts-type) absorbent article according to an embodiment of the present invention, a "urinary care product" is "Minor incontinence pants 1 (hereinafter also referred to as "incontinence pants 1") and "sanitary products" The following describes a shorts-type napkin 2 (hereinafter, simply referred to as "napkin 2") as a do.

[0056] <Basic structure of light incontinence pants 1> FIG. 1 is a schematic perspective view of light incontinence pants 1 according to the present embodiment. FIG. 3 is a plan view of the light incontinence pants 1 in the long state as viewed from the skin side in the thickness direction. FIG.

[0057] The "stretched state" of the light incontinence pants 1 (incontinence pants 1) refers to the state in which the incontinence pants 1 are stretched. Each elastic member (for example, the absorbent body elastic member 50 described later and the skin side sheets 22, 23, etc.) is stretched. By doing so, the entire incontinence pants 1 (the entire product) is stretched without wrinkles. Specifically, The dimensions of each member constituting the incontinence pants 1 (for example, the waistband member 20 described later, etc.) are This refers to the state in which the material has been stretched to the point where it matches or is close to the dimensions of the material itself.

[0058] In the pants-type state shown in FIG. 1, the incontinence pants 1 have a "vertical direction", a "lateral direction", and a "front-rear direction" that are mutually perpendicular. Also, as shown in FIG. 3, the incontinence pants 1 have a "thickness direction" in which each member is layered. In the vertical direction, the side that is the wearer's torso side when the wearer wears the incontinence pants 1 is the "upper side", and the side that is the wearer's crotch side is the "lower side". In the front-rear direction, the side that is the wearer's stomach side when the pants are worn is the "front side", and the side that is the wearer's back side is the "rear side". In the thickness direction, the side that comes into contact with the wearer's skin when the wearer wears the incontinence pants 1 is the "skin side", and the opposite side is the "non-skin side".

[0059] Furthermore, the incontinence pants 1 have a "vertical direction" and a "horizontal direction" that are perpendicular to each other when in the unfolded state shown in Fig. 2. The "vertical direction" is the direction along the up-down direction in a pants-type garment, and the "horizontal direction" is the direction along the left-right direction in a shorts-type garment.

[0060] The incontinence pants 1 of this embodiment comprise a liquid-absorbent main body 10 (corresponding to the "first absorbent main body") that absorbs liquids such as urine, and a waistline member 20 (corresponding to the "first waistline member") that is arranged on the non-skin side of the absorbent main body 10 and is placed around the wearer's waist when the incontinence pants 1 are worn.

[0061] (Absorbent body 10) Fig. 4 shows a plan view and a cross-sectional view of the absorbent main body 10. As shown in Fig. 2, the absorbent main body 10 (first absorbent main body) of this embodiment has a generally rectangular shape in plan view with the vertical direction (i.e., the long side direction of the absorbent main body 10) aligned along the up-down direction of the incontinence pants 1. As shown in Fig. 3 and Fig. 4, the absorbent main body 10 has an absorbent core 11 aligned along the vertical direction (up-down direction), a top sheet 12 arranged closer to the skin than the absorbent core 11, a second sheet 13 arranged between the top sheet 12 and the absorbent core 11, a back sheet 14 arranged closer to the skin than the absorbent core 11, and a side sheet 15 arranged on the non-skin side of the back sheet 14.

[0062] The absorbent core 11 is a member that absorbs and retains liquids such as urine, and is formed of liquid-absorbent fibers such as pulp fibers mixed with superabsorbent polymer (SAP). The absorbent core 11 may be covered with a liquid-permeable sheet member (core wrap sheet 11b) such as tissue paper or nonwoven fabric. The absorbent core 11 may be formed of a sheet in which superabsorbent polymer (SAP) is sandwiched between two sheet members.

[0063] The top sheet 12 is a liquid-permeable sheet member that can come into contact with the wearer's skin when worn, and is formed, for example, from a hydrophilic air-through nonwoven fabric or a spunbond nonwoven fabric.

[0064] The second sheet 13 is a sheet member having substantially the same function and structure as the top sheet 12, and is laminated on the non-skin side of the top sheet 12. It is not essential that the second sheet 13 is provided in the absorbent body 10.

[0065] The back sheet 14 is a breathable and liquid-impermeable sheet member for preventing liquid such as menstrual blood absorbed in the absorbent core 11 from leaking out to the outside, and is formed of, for example, a resin film.

[0066] The side sheet 15 is a sheet member laminated on the non-skin side of the back sheet 14, and is made of a hydrophobic nonwoven fabric such as an SMS (spunbond-meltblown-spunbond) nonwoven fabric. In this embodiment, the side sheet 15 forms a pair of leak-proof walls 30, 30.

[0067] The leakage preventing walls 30 are provided in pairs on both left and right sides of the absorbent main body 10, and are portions that correspond to so-called three-dimensional gathers. When the incontinence pants 1 are worn, the leakage preventing walls 30 stand up toward the wearer's skin from both left and right sides of the absorbent main body 10, thereby preventing liquids such as urine from leaking outward in the left and right directions (horizontal direction) of the absorbent main body 10.

[0068] In this embodiment, as shown in the cross-sectional view of Fig. 4, the side sheets 15 extend outwardly on both sides of the absorbent core 11 in the left-right direction (horizontal direction), while being folded in the thickness direction at both left-right end portions of the absorbent main body 10, and the end portions 15t are disposed closer to the skin than the absorbent core 11. Also, at the end portions 15t, as shown in Fig. 4, the side sheets 15 are folded back to be stacked in the thickness direction, and the leak-proof wall elastic members 31 are provided between the stacked side sheets 15, 15 in a state of stretching along the vertical direction. When the incontinence pants 1 are worn, the end portions 15t of the leak-proof wall portions 30 contract in the vertical direction (up-down direction) based on the stretchability exhibited by the leak-proof wall elastic members 31, so that the free end side of the end portions 15t stands up against the skin of the wearer.

[0069] The absorbent body 10 is provided with a high density portion 40 in which the density of the absorbent core 11 is higher than that of the surrounding area. The high density portion 40 is formed by compressing each member constituting the absorbent body 10 in the thickness direction. In the incontinence pants 1, the high density portion 40 is a linear compressed portion formed by arranging a plurality of dot-shaped compressed portions, each of which is linear, as shown in FIG. 4. By providing such linear compressed portions (high density portions 40), the liquid absorbent fibers of the absorbent core 11 are prevented from becoming loose and losing their shape. When the incontinence pants 1 are worn, the linear compressed portions (high density portions 40) become the starting points for bending, so that the absorbent core 11 is easily deformed three-dimensionally in accordance with the wearer's body shape, and easily fits the wearer's body. However, the incontinence pants 1 do not necessarily need to be provided with such linear compressed portions (high density portions 40).

[0070] The absorbent body 10 also includes an absorbent body elastic member 50 that stretches in the vertical direction (up-down direction). The absorbent body elastic member 50 is formed of, for example, rubber thread and has absorbent properties. On the non-skin side of the core 11 (specifically, between the back sheet 14 and the side sheet 15), The film is arranged in a state in which it is stretched in the vertical direction (up and down direction) at a predetermined stretch ratio. In the kinky pants 1, as shown in FIG. 4, five absorbent bodies are arranged at a predetermined interval in the left-right direction. Here, the "stretching ratio" of the elastic member is the elastic member in a stretched state. The length of the elastic member 50 in the absorber is divided by the length of the elastic member in the natural state. The shrinkability allows the absorbent body 10 to stretch along the vertical direction, and when the incontinence pants 1 are worn, In this case, the absorbent body 10 fits easily in the crotch area of ​​the wearer, and the absorbency of urine, etc. is improved. The arrangement, number, and elongation ratio of the absorbent body elastic members 50 can be set as appropriate. However, the absorbent elastic member 50 is not necessarily provided in the incontinence pants 1. It doesn't have to be.

[0071] (Waist member 20)

[0072] The waistband member 20 (first waistband member) is composed of one or more sheet members. The incontinence pants 1 are provided with a non-skin side sheet 21 and skin side sheets 22 and 23 (see FIG. In the following description, the waistband member 20 is arranged so that the width of the waistband member 20 is smaller than the center position CL in the vertical direction. The front (ventral) portion is a front waist portion 20f (corresponding to the first front waist portion), and the central position CL The portion on the rear side (back side) of the rear waistline portion 20a is also referred to as a rear waistline portion 20b (corresponding to a first rear waistline portion).

[0073] The non-skin side sheet 21 is a non-elastic sheet member that is placed closest to the skin side of the incontinence pants 1. For example, the nonwoven fabric is made of a spunbond nonwoven fabric or an SMS nonwoven fabric. As shown in the plan view of FIG. 2, the skin side sheet 21 has a shape that is narrowed toward the inside in the left-right direction at a central portion in the longitudinal direction (a portion including a central position CL).

[0074] The skin side sheet 22 is a stretchable sheet member (stretch sheet) laminated on the skin side of the non-skin side sheet 21 at the front side (ventral side) in the longitudinal direction. The skin side sheet 22 (stretch sheet) is formed of, for example, stretchable nonwoven fabric. The "stretchable nonwoven fabric" refers to a nonwoven fabric that contains stretchable fibers having stretchability and extensible fibers having lower shrinkage than the stretchable fibers, and that has been subjected to an appropriate stretching process such as gear stretching. The skin side sheet 22 of this embodiment can use, as the stretchable fibers, fibers of polyurethane-based elastomer, which is a type of thermoplastic elastomer having elasticity, and can use, as the extensible fibers, fibers of polypropylene (PP), which is a type of thermoplastic resin having inelasticity.

[0075] The skin side sheet 22 is joined to the non-skin side sheet 21 by a plurality of welds (not shown) arranged based on a predetermined pattern, thereby imparting stretchability at least along the left-right direction to the front waistline portion 20f. In this embodiment, the welds are formed using a known joining means such as ultrasonic welding.

[0076] The skin side sheet 23 is a stretchable sheet member laminated on the skin side of the non-skin side sheet 21 at the rear side (back side) in the longitudinal direction. The skin side sheet 23 has a structure similar to that of the skin side sheet 22. That is, the skin side sheet 23 is formed of a stretchable nonwoven fabric, and is joined to the non-skin side sheet 21 by a plurality of scattered welded parts (not shown). This provides the rear waist portion 20b with stretchability at least in the left-right direction.

[0077] In addition, waist elastic members 25 such as rubber threads are provided at the upper ends of the front waist portion 20f and the rear waist portion 20b so as to be stretchable in the left-right direction. By providing such waist elastic members 25, the fit at the waist opening 1a is improved, and the waist member 20 can be prevented from shifting position when the incontinence pants 1 are worn. It is desirable that at least a part of the waist elastic members 25 is arranged so as to overlap with the skin side sheets 22, 23 when viewed in the thickness direction (see Figs. 2 and 3). In this way, the left-right stretchability exhibited by the waist elastic members 25 and the left-right stretchability exhibited by the skin side sheets 22, 23 work together to further improve the fit of the incontinence pants 1 around the wearer's waist.

[0078] In addition, a post-treatment tape 70 is provided on the non-skin side of the rear waistband portion 20b, which is used when disposing of the incontinence pants 1 after use (see Figs. 2 and 3). The post-treatment tape 70 is made of a long strip-shaped tape member along the vertical direction (up and down direction), one vertical side of which is fixed to the non-skin side of the non-skin side sheet 21 of the rear waistband portion 20b, and has an adhesive part on the other vertical side. An adhesive is applied to the adhesive part, and before using the incontinence pants 1, a part of the post-treatment tape 70 is folded with the adhesive part facing inward, protecting the adhesive surface by preventing the adhesive part from being exposed to the outside (see Fig. 3).

[0079] When discarding the incontinence pants 1 after use, the incontinence pants 1 are rolled up so that the absorbent body 10 is on the inside, the folded post-treatment tape 70 is stretched and pulled to expose the adhesive part, and the adhesive part side is wrapped around the incontinence pants 1. This makes it possible to maintain the incontinence pants 1 in a rolled up state, and the incontinence pants 1 can be discarded without causing urine and other excrement adhering to the inside of the incontinence pants 1 (the absorbent body 10) to leak out to the outside.

[0080] The incontinence pants 1 are folded in half in the vertical direction (front-rear direction) of the absorbent body 10 and the waistline member 20 from the unfolded state shown in Fig. 2, with the vertical center position CL (shown by a dashed line in Fig. 2) as the folding position. In this folded state, both lateral (left-right) ends 20fe, 20fe of the front waistline portion 20f and both lateral (left-right) ends 20be, 20be of the rear waistline portion 20b overlapping in the front-rear direction are joined by a known joining method such as seal welding to form a pair of side joining portions 20we, 20we (corresponding to first side joining portions). As a result, the waistline member 20 (20f and 20b) folded in half is connected in a ring shape at the front side (ventral side) and the rear side (dorsal side), forming one waistline opening 1a and a pair of leg openings 1b as shown in Fig. 1, forming pants-type light incontinence pants 1.

[0081] <Basic structure of shorts-type sanitary napkin 2> Next, the basic structure of the shorts-type napkin 2 (napkin 2) will be described. Fig. 5 is a schematic perspective view of the shorts-type napkin 2 according to this embodiment. Fig. 6 is a plan view of the shorts-type napkin 2 in an expanded and stretched state, as viewed from the skin side in the thickness direction.

[0082] The "stretched state" in Fig. 6 is substantially the same as the "stretched state" described in Fig. 2. In other words, it refers to a state in which the dimensions of each component constituting the napkin 2 are stretched until they match or are close to the dimensions of that component alone. Similarly to the incontinence pants 1, the napkin 2 has a "vertical direction", a "lateral direction", and a "front-rear direction" that intersect with one another (see Figs. 5 and 6), and also has a "thickness direction" in which the components are layered (see Fig. 7 described below).

[0083] The napkin 2 comprises a liquid-absorbent main body 110 (corresponding to the "second absorbent main body") that absorbs excretory liquids such as menstrual blood, and a waistline member 120 (corresponding to the "second waistline member") that is arranged on the non-skin side of the absorbent main body 110 and is placed around the wearer's waist when the napkin 2 is worn.

[0084] (Absorbent body 110) 7 is a plan view and a cross-sectional view of the absorbent body 110. The absorbent body 110 (second absorbent body) of the napkin 2 has a structure substantially similar to that of the absorbent body 10 of the incontinence pants 1. That is, the absorbent body 110 of the napkin 2 comprises an absorbent core 111 and a A top sheet 112 is placed on the skin side of the absorbent core 111. A second sheet 113 is disposed between the absorbent core 111 and a back sheet 114 is disposed on the non-skin side of the absorbent core 111. A back sheet 114 and a side sheet 115 arranged on the non-skin side of the back sheet 114 are However, in the absorbent body 110 (second absorbent body) of the napkin 2, the absorbent core The configuration of 111 is the absorbent core 11 of the absorbent body 10 (first absorbent body) of the incontinence pants 1 are different.

[0085] The absorbent core 111 provided in the absorbent body 110 (second absorbent body) is configured to absorb excretion of menstrual blood and the like. It is a material that absorbs and retains liquid, and is made of liquid-absorbent fibers such as pulp fibers. The absorbent core 111 also contains superabsorbent polymer (SAP) just like the incontinence pants 1. However, the SAP content is lower than that of pulp fibers. The menstrual blood that is absorbed by the napkin 2 has a high viscosity and low fluidity compared to urine. It is difficult to be absorbed by the absorbent polymer (SAP). Therefore, the absorbent core 11 of the second absorbent body In 1, the amount of superabsorbent polymer (SAP) contained per unit volume is It is smaller than the amount of pulp fiber it contains.

[0086] For example, in the incontinence pants 1, the pulp contained in the absorbent core 11 (first absorbent body) If the amount of fiber is 1, the amount of superabsorbent polymer (SAP) is about 0.5 to 1.2. That is, in the incontinence pants 1, the pulp contained in the absorbent core 11 (first absorbent body) The ratio of superabsorbent polymer to fiber is 50% or more. In some cases, the sheets may not contain pulp fibers. 2, the amount of pulp fiber contained in the absorbent core 111 (second absorbent body) was set to 1. In this case, the amount of superabsorbent polymer (SAP) is about 0 to 0.3. That is, in the napkin 2, the ratio of superabsorbent polymer to pulp fiber contained in the absorbent core 111 (second absorbent main body) is 30% or less.

[0087] With this configuration, the absorbent body 110 (second absorbent body) of the napkin 2 is structured so that highly viscous excretory fluid such as menstrual blood is easily retained between multiple pulp fibers, rather than being absorbed by superabsorbent polymer (SAP). Also, by reducing the content of superabsorbent polymer (SAP), the rigidity of the absorbent body 110 becomes relatively low, so that when the napkin 2 is worn, it is unlikely to cause discomfort in sensitive areas such as the vaginal opening, and therefore it is unlikely to cause discomfort to the wearer.

[0088] In the absorbent body 110 (second absorbent body) of the napkin 2, the configuration other than the absorbent core 111 (top sheet 112 to side sheet 115) is basically the same as the corresponding configurations (top sheet 12 to side sheet 15) of the absorbent body 10 (first absorbent body) of the incontinence pants 1.

[0089] The absorbent main body 110 (second absorbent main body) of the napkin 2 is provided with a high density portion 140 in which the density of the absorbent core 111 is higher than that of the surrounding portion. The high density portion 140, like the high density portion 40 of the incontinence pants 1, is a linear compressed portion formed by arranging a plurality of dot-shaped compressed portions that compress each member constituting the absorbent main body 110 in the thickness direction. The absorbent main body 110 is also provided with an absorbent body elastic member 150 that stretches along the vertical direction (up and down direction). Like the absorbent body elastic member 50 of the incontinence pants 1, the absorbent body elastic member 150 is disposed on the non-skin side of the absorbent core 111 in a state of being stretched in the vertical direction at a predetermined stretch ratio, and provides the absorbent main body 110 with vertical stretchability.

[0090] (Waist member 120)

[0091] The configuration of the waistline member 120 (second waistline member) of the napkin 2 is basically the same as the configuration of the waistline member 20 (first waistline member) of the incontinence pants 1. That is, the waistline member 120 (second waistline member) has a non-skin-side sheet 121 which is a non-stretchable sheet member arranged closest to the skin, a skin-side sheet 122 having stretchability laminated on the skin side of the non-skin-side sheet 121 on the front side (ventral side) in the longitudinal direction, and a skin-side sheet 123 having stretchability laminated on the skin side of the non-skin-side sheet 121 on the rear side (dorsal side) in the longitudinal direction.

[0092] When forming a pants-type (shorts-type) shorts-type napkin 2, the absorbent body 110 and the waistline member 120 are folded in half in the vertical direction (front-rear direction) from the developed state shown in Fig. 6, with the center position CL in the vertical direction as the folding position. Then, in this folded state, the lateral (left-right) end portions 120fe, 120fe of the front waistline portion 120f (corresponding to the second front waistline portion) and the lateral (left-right) end portions 120be, 120be of the rear waistline portion 120b (corresponding to the second rear waistline portion) overlapping in the front-rear direction are joined by a known joining means such as seal welding, forming a pair of side joining portions 120we, 120we (corresponding to the second side joining portion). As a result, the waistline member 20 (20f and 20b) folded in half is connected in a ring shape at the front side (ventral side) and the rear side (back side), forming one waistline opening 2a and a pair of leg openings 2b as shown in Fig. 5.

[0093] <Condition of pants-type absorbent products during distribution> The light incontinence pants 1 and the shorts-type napkin 2 are folded compactly and individually wrapped in a specific packaging material (also called "individually wrapped"), and are distributed on the market in a packaged state of one or more individual wrappers. The state of the light incontinence pants 1 and the shorts-type napkin 2 during distribution will be described below.

[0094] Fig. 8 is a diagram illustrating a folding method for packaging the light incontinence underwear 1. Fig. 9 is a diagram illustrating a method for individually packaging the light incontinence underwear 1 in a folded state. Fig. 10 is a diagram illustrating a method for packaging an individually wrapped package of a plurality of light incontinence underwear 1. Note that, since the folding method, individual packaging method, and packaging method for distribution to the market are the same for the incontinence underwear 1 and the napkin 2, the following description will mainly take the incontinence underwear 1 as an example.

[0095] When folding the incontinence pants 1 for individual packaging, first, as shown in Fig. 8A, the pants-shaped incontinence pants 1 are placed on a plane so that the rear side in the front-to-rear direction (the rear waist portion 20b) faces vertically upward. Then, both left and right sides of the waist member 20 are folded from the outside to the inside at a pair of first folding lines F11, F12 along the up-down direction (vertical direction). At this time, as shown by the arrows in Fig. 9A, the waist member 20 is folded so that the rear waist portion 20b is on the inside in the thickness direction. Note that the first folding lines F11, F12 do not need to be parallel to the up-down direction and may be inclined to some extent.

[0096] Next, as shown in Fig. 8B, the waist member 20 and the absorbent main body 10 are folded in half in the top-bottom direction at a second folding line F2 along the left-right direction. The incontinence pants 1 folded in this way are in a compact folded state having a substantially rectangular shape as shown in Fig. 8C. In the folded state of the incontinence pants 1, the rear waist portion 20b is folded inward, the front waist portion 20f is exposed to the outside (atmosphere side), and the rear waist portion 20b and the post-treatment tape 70 are hidden inside.

[0097] The folded incontinence pants 1 are individually wrapped in a wrapping material 81 (corresponding to a first wrapping material) made of a predetermined sheet material such as nonwoven fabric or film. When wrapping the incontinence pants 1, the folded incontinence pants 1 are placed near the center of the wrapping material 81, as shown in Fig. 9A. Then, both left and right sides of the first wrapping material 81 are folded from outside to inside at a pair of wrapping material folding lines FS1 and FS2 along the up-down direction (vertical direction) to wrap the incontinence pants 1 inward. Packaging to encase.

[0098] Next, the left and right side portions of the folded first packaging material 81 are overlapped in the thickness direction. The parts are joined at first joining parts 811 along the up-down direction as shown in FIG. 9B. The first packaging material 81 is attached to both ends in the up-down direction by a pair of second joint portions 812 extending in the left-right direction. , 812. As a result, the folded incontinence pants 1 are wrapped in the first packaging material 81. The individually packaged incontinence pants 1 are packaged together (individually packaged 1ip). The contents 1 (individually wrapped body 1ip) are protected from foreign objects by the first wrapping material 81. Therefore, the incontinence pants 1 are less likely to be damaged during distribution, and the absorption performance is less likely to deteriorate. By carrying such an individually wrapped package 1ip, the user can easily use the product when out and about. It is possible to replace used incontinence pants 1 with new incontinence pants 1, etc.

[0099] The napkin 2 is also folded in the same manner as in FIGS. 8A to 8C, and is the same as the first packaging material 81. Using the same second packaging material 82, individual packaging is performed in the same manner as in Figs. 9A and 9B. The folded napkin 2 is wrapped in the second packaging material 82 to form an individual package 2ip. become.

[0100] The individually packaged incontinence pants 1 (individually packaged body 1ip) are usually packed in a predetermined container member in multiple pieces. The packaged absorbent articles are distributed to the market as containers (packages). When packaging, first, the container member 200 formed in a bag shape as shown in FIG. 10A is The storage member 200 is made by attaching a leak-proof resin film sheet to the upper side in the vertical direction. In FIG. 10A, the container is formed in a bag shape having an opening 201. The container member 200 is formed in a substantially rectangular parallelepiped shape, and has a first direction and a second direction that are perpendicular to each other on a horizontal plane.

[0101] A plurality of individual packages 1ip are arranged in parallel in such a bag-shaped containing member 200 from the vertically upper opening 201. Fig. 10A shows an example in which six individual packages 1ip are arranged in the thickness direction along the first direction of the containing member 200. However, the orientation and number of the individual packages 1ip when being contained in the containing member 200 are not limited to the example of Fig. 10A. Also, incontinence pants 1 in a folded state (not individually packaged state) as shown in Fig. 8C may be directly contained in the containing member 200.

[0102] After a predetermined number of incontinence pants 1 are accommodated in the accommodation member 200, the opening 201 of the accommodation member 200 is folded in a so-called gusset manner, and opposing surfaces at the upper end are joined along a first direction to form a sealed portion 205. As a result, a plurality of individually packaged incontinence pants 1 (individually packaged bodies 1ip) are packaged in the accommodation member 200 to form a accommodation body 1pkg of incontinence pants 1. Similarly, napkins 2 (individually packaged bodies 2ip) are packaged to form a accommodation body 2pkg. Then, the incontinence pants 1 and napkins 2 are displayed as such accommodation bodies on the shelves of sales stores or displayed on web screens on the Internet.

[0103] Fig. 11 is a diagram showing an example of a package of incontinence pants 1 and napkin 2. Fig. 11A shows an external view of an incontinence pants 1 container 1pkg containing an individual package 1ip of incontinence pants 1, and Fig. 11B shows an external view of a napkin 2 container 2pkg containing an individual package 2ip of napkin 2.

[0104] Various information is displayed on the surface of the container 1pkg of the incontinence pants 1. In FIG. 11A, a brand name 211, a product name 212, a sales company name 213, and a size indication 214 are displayed. The brand name 211 is information indicating the brand of the absorbent article group including the incontinence pants 1, and for example, a mark such as "Sofi" or a brand logo is displayed. The product name 212 is information indicating the type of absorbent article contained therein, and in the case of the incontinence pants 1, information such as "urinary care pants" is displayed so that the user can understand at a glance that it is an incontinence care product. The sales company name 213 is information indicating the company that sells the product, and for example, "Unicharm". In addition to the sales company, information such as the manufacturing company may be displayed. The size indication 214 is information indicating the size of the incontinence pants 1, and for example, sizes such as S, M, L, and XL are displayed.

[0105] Also, the surface of the napkin 2 container 2 pkg displays information similar to that of the incontinence pants 1 container 1 pkg. In Fig. 11B, a brand name 221, a product name 222, a sales company name 223, and a size indication 224 are displayed. Among these, the brand name 221, the sales company name 223, and the size indication 224 are the same as the brand name 211, the sales company name 213, and the size indication 214 of the incontinence pants 1 container 1 pkg, respectively. For example, the brand name 221 displays the same "Sofi" mark as the incontinence pants 1 container 1 pkg. Therefore, the user can easily recognize that the napkin 2 is part of a series of absorbent articles bearing the "Sofi" brand, and can make a purchase with confidence.

[0106] On the other hand, the napkin 2 container 2 pkg displays "sanitary napkin" as the product name 222. In other words, a different product name is displayed from the product name 212 "urinary care pants" of the incontinence pants 1 container 1 pkg. This makes it clear that the napkin 2 is a sanitary product, even if urinary care products and sanitary products are available under the same brand (Sofi), and the user can purchase the product without making a mistake.

[0107] <Manufacturing method of pants-type absorbent article> The pants-type absorbent article, the incontinence pants 1 and the napkin 2, according to this embodiment, can be manufactured on a common manufacturing line. Below, an overview of a method for manufacturing the incontinence pants 1 and the napkin 2 using a manufacturing device 500 (manufacturing line) for pants-type absorbent articles will be described.

[0108] (Manufacture of incontinence pants 1) First, a method for manufacturing the incontinence pants 1 will be described. Fig. 12 is a flow diagram showing the manufacturing process for the incontinence pants 1 according to this embodiment. Fig. 13 is a schematic diagram for explaining a manufacturing device 500 for manufacturing the incontinence pants 1. Note that Figs. 12 and 13 explain typical steps involved in the manufacturing of pants-type absorbent articles, and do not show all of the manufacturing steps.

[0109] The manufacturing apparatus 500 shown in Fig. 13 intermittently manufactures incontinence pants 1 as pants-type absorbent articles by sequentially performing the steps shown in Fig. 12. The manufacturing apparatus 500 includes an absorbent core forming mechanism 511, a skin side material joining mechanism 512, a squeezing mechanism 513, a non-skin side material joining mechanism 514, an absorbent main body cutting mechanism 515, an absorbent main body transfer mechanism 520, a waist member forming mechanism 531, a leg opening forming mechanism 532, a pants-type forming mechanism 533, an absorbent article cutting mechanism 534, a folding mechanism 541, and an individual packaging mechanism 542.

[0110] In the manufacturing apparatus 500, the absorbent body 10 is first manufactured by steps S101 to S105. First, an absorbent core forming step is performed to form the absorbent core 11 (S101). In the absorbent core forming step, a continuous body of carrier sheets (for example, the above-mentioned continuous body of core wrap sheet 11b) that is continuous in the conveying direction is continuously conveyed at a predetermined speed along the conveying direction. The "conveying direction" is the direction in which the pants-type absorbent article is conveyed from the upstream side to the downstream side of the manufacturing apparatus 500, and is also referred to as the "MD direction" hereinafter. As shown in FIG. 13, depending on the layout of the manufacturing apparatus 500, the conveying direction (MD direction) may change to a different direction during the conveying process.

[0111] In the absorbent core forming process, vertically above the transported carrier sheet (11b), The absorbent core forming mechanism 511 is provided with a pattern drum 511d. The ram 511d is arranged to move in a direction perpendicular to the conveying direction (also called the "CD direction" in FIG. 13). The rotation axis is aligned along the depth direction of the surface, and the outer periphery of the rotation axis has a predetermined shape. A plurality of recesses are provided along the circumferential direction. Each recess is provided with an absorbent material supply device 511m. The absorbent material, such as superabsorbent polymer (SAP) or pulp fiber, is supplied to the recess. By laminating absorbent material in the recess, the shape of the recess (e.g. rectangular or hourglass shape) can be adjusted. The absorbent core 11 formed in the recess is When the turn drum 511d rotates and the carrier sheet faces the recessed portion, The image is transferred onto the carrier sheet.

[0112] Next, the top sheet 12 and the second sheet 13 are joined to the skin side of the absorbent core 11. In the skin-side material joining process, the skin-side material is joined by bonding the skin-side material (S102). As a material, a continuous top sheet 12 in a state of being connected in the vertical direction is arranged in a predetermined direction along the MD direction. Similarly, the continuous second sheet 13 connected in the vertical direction is conveyed at a speed of The absorbent core is transported at a predetermined speed along the MD direction. The second sheet 13 and the toe sheet 11 are connected to each other by the skin side material joining mechanism 512. The continuous pieces of the cap sheet 12 are joined together, and the absorbent core is attached to the cap sheet 12 by a joining means such as a hot melt adhesive. It is joined to the skin side of A11 in the thickness direction (the vertically upward side in Figure 13).

[0113] Next, a compression step is carried out to form linear compressed portions (high density portions 40) in the absorbent core 11. In the compression step, a compression mechanism 513 compresses predetermined locations of the laminate of the top sheet 12, the second sheet 13, and the absorbent core 11 from the skin side in the thickness direction, thereby forming compressed lines (high density portions 40) as shown in Fig. 4. Note that if there is no need to provide compressed lines (high density portions 40) in the absorbent main body 10 of the incontinence pants 1, this step (S103) may be omitted.

[0114] Next, a non-skin side material joining step is performed in which the back sheet 14 and the side sheet 15 are joined to the non-skin side of the absorbent core 11 (S104). In the non-skin side material joining step, a continuous body of the back sheet 14 connected in the vertical direction is transported at a predetermined speed along the MD direction as the non-skin side material. Similarly, a continuous body of the side sheets 15 connected in the vertical direction is transported at a predetermined speed along the MD direction. In addition, when the absorbent body 10 is provided with the absorbent elastic member 50, the continuous body of the absorbent elastic member 50 in a state of being stretched in the longitudinal direction is attached so as to be sandwiched between the back sheet 14 and the side sheet 15. Then, the continuous back sheet 14 and the continuous side sheet 15 are joined by a non-skin side material joining mechanism 514 to the absorbent core 11 being transported in the MD direction, and joined to the non-skin side in the thickness direction of the absorbent core 11 (vertically downward in Fig. 13) using a joining means such as a hot melt adhesive. After the side sheets 15 are attached to the non-skin side of the absorbent core 11, both ends in the lateral direction (CD direction) are folded inward to form the leakage prevention walls 30 (see Fig. 4).

[0115] Next, an absorbent body cutting step is performed in which the continuous body of the vertically continuous top sheet 12, etc. is cut into individual pieces (S105). In the absorbent body cutting step, a pair of cutter rolls 515c provided in the absorbent body cutting mechanism 515 cuts the continuous body into pieces of a predetermined length in the vertical direction, thereby forming individual absorbent bodies 10. The formed absorbent bodies 10 are transported as they are downstream in the MD direction and supplied to an absorbent body transfer drum 520d, which will be described later.

[0116] Next, a waistband member forming process is performed in which the non-skin side sheet 21 and the skin side sheets 22, 23 are joined together to form the waistband member 20 (S106). In the waistband member forming process, the continuous non-skin side sheet 21 in a state of being connected in the horizontal direction is transported at a predetermined speed along the transport direction (MD direction). Similarly, the continuous skin side sheets 22, 23 in a state of being connected in the horizontal direction are transported at a predetermined speed in a state of being stretched along the MD direction. In addition, in FIG. 13, in the process of transporting the base material sheet (nonwoven fabric) constituting the skin side sheets 22, 23, a stretching process such as gear stretching is performed, so that the base material sheet is given elasticity along the MD direction (the horizontal direction of the skin side sheets 22, 23). Then, the continuous non-skin side sheet 21 transported in the MD direction and the continuous skin side sheets 22, 23 are joined by a waistband member forming mechanism 531 using a joining means such as ultrasonic welding in a state in which they are stacked in the thickness direction, and the continuous waistband member 20 is formed.

[0117] Next, an absorbent body transfer step is performed in which the absorbent body 10 formed in S101 to S105 is transferred to the continuous body of the waistline member 20 (S107). In the absorbent body transfer step, the absorbent body 10 is transferred to the continuous body of the waistline member 20 using an absorbent body transfer drum 520d provided in the absorbent body transfer mechanism 520. The absorbent body transfer drum 520d is a drum that is rotated about a rotation axis along a direction perpendicular to the MD direction (CD direction), and can rotate while holding the absorbent bodies 10 one by one along the circumferential direction. In this embodiment, the absorbent body transfer drum 520d receives each absorbent body 10 formed in the process of S105 with the vertical direction of the absorbent body 10 aligned with the MD direction, and holds it on the outer circumferential surface. Then, while rotating while holding the absorbent main body 10, the orientation of the absorbent main body 10 is changed so that the lateral direction of the absorbent main body 10 is aligned with the MD direction, and the absorbent main body 10 is transferred to the continuous body of waistline members 20 transported in the MD direction. After the absorbent main body 10 is transferred, waistline elastic members 25 are attached to the waistline members 20.

[0118] Next, a leg opening forming step is performed (S108) in which portions that become the leg openings 1b are cut out from the continuous waistline member 20. In the leg opening forming step, a leg opening forming mechanism 532 cuts out curved portions along the outer edge 1be of the leg openings shown in Fig. 2 from the continuous belt-like (rectangular) waistline member 20. The cut-out portions become a pair of leg openings 1b, 1b in the pants-type shape.

[0119] Next, a pants-shaped forming process is performed in which the various base materials being transported in the MD direction are formed into a pants-shaped shape (S109). In the pants-shaped forming process, the pants-shaped forming mechanism 533 folds the waist member 20 and the absorbent main body 10 in half at a center position CL (see FIG. 2) in the vertical direction (CD direction) to form side joining portions 20We, 20We..., so that a plurality of incontinence pants 1, 1... are continuous in the transport direction (MD direction).

[0120] Next, an absorbent article cutting step is performed in which the continuous incontinence pants 1, 1 in the MD direction are cut into individual incontinence pants 1 (S110). In the absorbent article cutting step, the incontinence pants 1, 1 conveyed in a continuous state in the MD direction are cut into a predetermined length in the MD direction (length W1 in FIG. 2) by a cutter roll 534c provided in the absorbent article cutting mechanism 534. In this way, individual incontinence pants 1 are manufactured.

[0121] Next, a folding step is performed in which the manufactured incontinence pants 1 are folded for packaging (S111). In the folding step, the incontinence pants 1 are folded using an impeller folding device or the like (not shown) provided in the folding mechanism 541 in the procedure described in FIG.

[0122] Next, an individual packaging process is performed in which the folded incontinence pants 1 are individually packaged (S112). In the individual packaging process, the incontinence pants 1 are individually packaged using an individual packaging sail and an individual packaging sealing device (not shown) provided in the individual packaging mechanism 542 according to the procedure described in Fig. 9, to become individually packaged incontinence pants 1 (individually packaged body 1ip).

[0123] The incontinence pants 1 in an individually packaged state (individually packaged body 1ip) are downstream in the MD direction of the individual packaging mechanism 542. A predetermined number of packages are packed into the container 200 using a container device (not shown) provided on the side of the container. The incontinence pants are packaged in a package of one package per kg as shown in FIG. 11A and are then shipped to the market. To circulate.

[0124] (Manufacture of Napkin 2) Next, a method for manufacturing the napkin 2 will be described. The method for manufacturing the napkin 2 is the same as that for manufacturing the incontinence pants 1. For example, the same manufacturing line as the manufacturing line can be used. In the case where the incontinence pants 1 are manufactured by the above-mentioned method, a setup for changing a part of the mechanism of the manufacturing apparatus 500 is required. By replacing the napkin 2, the napkin 2 can be manufactured. 1 is a flow diagram for explaining a method for manufacturing incontinence pants 1 and napkins 2 using the method of manufacturing the ... do.

[0125] First, the incontinence pants 1 are manufactured using the manufacturing apparatus 500 according to the process described with reference to FIG. Assume that a manufacturing process for the incontinence pants 1 is being carried out (S201). Next, The production is stopped, and a changeover step is performed to produce napkins 2 using the production apparatus 500. The changeover process is described later (S202). Next, the manufacturing equipment 500 is A napkin 2 manufacturing process is carried out by using the napkin 2 (S203). The steps performed in the manufacturing process are substantially the same as those in the manufacturing process of the incontinence pants 1 shown in FIG. When the napkin 2 manufacturing process is being carried out using the manufacturing device 500, a changeover is performed. By doing so, it is possible to carry out the manufacturing process of the incontinence pants 1 again. In the manufacturing apparatus 500, by changing the setup of some of the mechanisms (S202), it is possible to appropriately manufacture both the incontinence pants 1 and the napkins 2.

[0126] As described above, the basic configuration of the napkin 2 is substantially the same as that of the incontinence pants 1, and the external shape and dimensions of the waist member 120(20) and the like can be the same. On the other hand, the napkin 2 and the incontinence pants 1 differ in part in the composition of the absorbent core 111(11) of the absorbent main body 110(10). Specifically, the incontinence pants 1 are a urine care product and need to efficiently absorb and retain liquids such as urine, so the absorbent core 11 contains a large amount of superabsorbent polymer (SAP). On the other hand, the napkin 2 is a sanitary product and is intended to absorb menstrual blood and the like, so the absorbent core 111 contains a smaller amount of superabsorbent polymer (SAP) than the incontinence pants 1, or does not contain any superabsorbent polymer (SAP).

[0127] Therefore, in the changeover step (S202), the configuration of the absorbent core forming mechanism 511 in the manufacturing apparatus 500 is changed, and the content ratio of the absorbent material (SAP, pulp fiber, etc.) supplied from the absorbent material supply device 511m to the pattern drum 511d is changed, thereby making it possible to form the absorbent main body 110 (absorbent core 111) of the napkin 2. In other words, by changing the basis weight of the superabsorbent polymer (SAP) when manufacturing the absorbent main body 10 (absorbent core 11) of the incontinence pants 1 and the basis weight of the superabsorbent polymer (SAP) when manufacturing the absorbent main body 110 (absorbent core 111) of the napkin 2, the manufacturing apparatus 500 can interchangeably carry out the incontinence pants 1 manufacturing step (S201) and the napkin 2 manufacturing step (S203).

[0128] Furthermore, if the incontinence pants 1 and the napkin 2 have different configurations other than the absorbent main body 10 (110), the mechanisms related to those configurations are also changed. For example, if the linear compressed parts (high density parts 40) are not provided and the compressing step (S103) is omitted in the manufacture of the incontinence pants 1, the compressing step (S103) must be performed in the manufacture of the napkin 2, so the compressing mechanism 513 is operated to form linear compressed parts (high density parts 140) in the absorbent main body 110. Furthermore, if the shape of the leg openings 1b of the incontinence pants 1 differs from the shape of the leg openings 2b of the napkin 2, the configuration of the pants-shaped forming mechanism 533 is changed, and adjustments are made to change the cutouts of the outer edges 1be of the leg openings in the incontinence pants 1 and the cutouts of the outer edges 2be of the leg openings in the napkin 2.

[0129] On the other hand, if the first waist member 20 of the incontinence pants 1 and the second waist member 120 of the napkin 2 are similar in components and dimensions, the steps from S106 onwards (including S111: folding step and S112: packaging step) described in Fig. 12 can be made common to the incontinence pants 1 and the napkin 2. In other words, it is possible to manufacture the waist member without changing the setup of the manufacturing apparatus 500. In this way, it becomes possible to efficiently manufacture the incontinence pants 1 and the napkin 2 using a common manufacturing line (manufacturing apparatus 500).

[0130] <About the external appearance of incontinence pants 1 and napkin 2> In this embodiment, by making the incontinence pants 1 and the napkin 2 have a common external shape, it is possible to make it difficult for a third party other than the user to distinguish the types of absorbent articles used from the external shape. In other words, it is possible to make it difficult for a third party other than the user to distinguish the types of the incontinence pants 1 and the napkin 2. Note that the incontinence pants 1 and the napkin 2 are usually sold in multiple sizes (S size, M size, L size, etc.), but regardless of the size of each product, the external shape of the product itself (horizontal lengths W1, W2 and vertical lengths L20we, L120we, etc. described later) will be compared. For example, when comparing an M-size product of incontinence pants 1 with an L-size product of napkin 2, if the horizontal lengths W1, W2 and vertical lengths L20we, L120we are the same, they are considered to have a common external shape.

[0131] The incontinence pants 1 and the napkin 2 have at least the following commonalities in their external shapes: the horizontal length W1 of the first waist member 20 of the incontinence pants 1 in the stretched state is equal to the horizontal length W2 of the second waist member 120 of the napkin 2 in the stretched state, and the vertical length L20we of the first side joint portion 20we of the incontinence pants 1 in the stretched state is equal to the vertical length L120we of the second side joint portion 120we of the napkin 2 in the stretched state. With this configuration, the first waist member 20 of the incontinence pants 1 and the second waist member 120 of the napkin 2 look the same in appearance, so that the external appearance of each product has approximately the same shape even in the pants-type state of Fig. 1 or Fig. 5. Therefore, even if a third party sees a user of the incontinence pants 1 using (wearing) the pants-type absorbent article while traveling or otherwise out, it is difficult for the third party to know whether the pants-type absorbent article is a "urinary care product" or a "sanitary product."

[0132] Due to manufacturing errors that occur when manufacturing the incontinence pants 1 and the napkin 2 using a manufacturing apparatus 500 as shown in Fig. 13, for example, the horizontal length W1 of the first waistline member 20 and the horizontal length W2 of the second waistline member 120 may not be strictly equal. However, even if a difference occurs in the dimensions of the incontinence pants 1 and the napkin 2 within the range of normally occurring manufacturing errors, the dimensions of both are considered to be equal. For example, if the difference in dimensions between the incontinence pants 1 and the napkin 2 is within 5%, the dimensions of both are considered to be equal.

[0133] Furthermore, because the way in which the incontinence pants 1 are folded when packaged is the same as the way in which the napkin 2 is folded when packaged, the external shape of the individual package 1ip of the incontinence pants 1 and the individual package 2i of the napkin 2 are substantially the same. Therefore, even if a friend or the like sees the user carrying the individual package 1ip of the incontinence pants 1 in a bag or the like, it is difficult for the friend or the like to know whether the pants-type absorbent article is a "urinary care product" or a "sanitary product."

[0134] As shown in FIG. 11, the container 1pkg of the incontinence pants 1 and the container 2 of the napkin The only difference between the 2pkg and 2pkg is the product name displayed on the package. For example, in Figures 11A and 11B, the information on the incontinence pants is the same for both. The product name 212 of the 1st package 1pkg is displayed as "urinary care pants" and the 2nd package The product name 222 of the 2-pkg item is displayed as "sanitary napkins." On the other hand, the sales company name 21 The indications 3,223 and brand names 211,221 are common to each other.

[0135] Therefore, when viewed from a distance at a storefront, the container of one incontinence panty is 1 pack. It is difficult to distinguish between the 2 pack of 2 napkins and the 2 pack of 2 g. When viewing the product, the user can easily identify the product by checking the product name 212, 222 displayed on the package. Therefore, the customer (purchaser) can purchase the correct type of pants-type absorbent article. The user (purchaser) can purchase the pants-type absorbent article without letting others know the type of the pants-type absorbent article. You can purchase the correct type without any worries.

[0136] In this manner, in this embodiment, the user himself / herself is not required to recognize the type of pants-type absorbent article. However, it is possible to make it difficult for a third party to identify the product, so it is recommended to use pants-type absorbent articles. This can reduce the psychological resistance of users when using or purchasing the product.

[0137] In addition, 1 individually packaged incontinence pants (1 individually packaged body) and 2 individually packaged napkins ( It is advisable to use the same design for the individual package (package 2ip). Here, the "design" of the individual package means For example, the letters, designs, patterns, etc. on the surface of the individual package 1ip and the individual package 2ip This refers to the arrangement of the first packaging material 81 and the second packaging material 82, and the colors of the first packaging material 81 and the second packaging material 82. In the individually packaged state as shown in Fig. 9B, if the individual packaging body 1ip of the incontinence pants 1 and the individual packaging body 2ip of the napkin 2 have the same design, it will be difficult for a third party to distinguish between them in appearance, and therefore the user can make it difficult for a third party to know the type of pants-type absorbent article (individually packaged body) that he or she is using (possessing).

[0138] As described in Fig. 11A and Fig. 11B, in this embodiment, the design of the container 1pkg (package) in which the individual package 1ip of the incontinence pants 1 is contained is different from the design of the container 2pkg (package) in which the individual package 2ip of the napkin 2 is contained, in which the product names 212, 222 are displayed. Therefore, even if the design of the individual package 1ip of the incontinence pants 1 and the individual package 2ip of the napkin 2 are the same, the user himself can distinguish between them. For example, when the user uses the incontinence pants 1, the user takes out the individual package 1ip from the container 1pk (package) of the incontinence pants 1 and uses (carries) it, so that the user himself can know that the type of the pants-type absorbent article is the incontinence pants 1. In this way, since the designs of the packages of the pants-type absorbent articles are different, the user can use the individually packaged pants-type absorbent articles without making a mistake in the type.

[0139] On the other hand, the individually packaged incontinence pants 1 (individually packaged body 1ip) and the individually packaged napkin 2 (individually packaged body 2ip) may have different designs. For example, the color of the individual package 1ip of the incontinence pants 1 may be white, and the color of the individual package 2ip of the napkin 2 may be light blue. In this case, since it is unlikely that a third party would know in advance which of the white individual package and the light blue individual package is the incontinence pants 1 and which is the napkin 2, only the user can distinguish the types of the two. Also, in cases where it is unlikely that the individually packaged pants-type absorbent article is visible to a third party, the different designs of the individual package 1ip and the individual package 2ip can prevent the user from mistaking the type of pants-type absorbent article.

[0140] Incidentally, even if the incontinence pants single package 1ip and the individual package 2ip of the napkin 2 have different designs, it is desirable that the design of the container 1pkg (package) of the incontinence pants 1 differs from the design of the container 2pkg (package) of the napkin 2. In this way, it becomes more difficult for the user to mistake the type of individually packaged pant-type absorbent article, and it is also possible to prevent the user from purchasing the wrong type of pant-type absorbent article at a store or the like.

[0141] In addition, it is preferable that the design of the incontinence pants 1 visible when viewed through the outside of the first packaging material 81 in the individually packaged incontinence pants 1 (individually packaged body 1ip) and the design of the napkin 2 visible when viewed through the outside of the second packaging material 82 in the individually packaged napkin 2 (individually packaged body 2ip) are similar. For example, when a user takes out the individual package 1ip from a bag or the like to use the incontinence pants 1 while out and about, the contents (incontinence pants 1) may be visible from the outside of the first packaging material 81 to a third party due to the amount of light, etc. In such a case, if the designs of the individual package 1ip and the individual package 2ip are similar when viewed through the eyes, it is possible to make it difficult to tell the type of pants-type absorbent article from the outside even if a third party can see it.

[0142] On the other hand, the design of the incontinence pants 1 visible when viewed through the first packaging material 81 from the outside in the individually packaged incontinence pants 1 (individually packaged body 1ip) may be different from the design of the napkin 2 visible when viewed through the second packaging material 82 from the outside in the individually packaged napkin 2 (individually packaged body 2ip). For example, if a third party only glances at an individual package of pant-type absorbent articles held by a user from the outside for a moment, the third party is unlikely to correctly identify the type of pant-type absorbent article inside the packaging material. In contrast, a user can carefully view the individual package through light from the outside, and therefore can correctly identify the type of pant-type absorbent article inside. Therefore, by making the designs of the two different, it is possible to make it difficult for a third party to tell the type of pant-type absorbent article, while making it easy for the user to identify it.

[0143] The visibility of the individual packages 1ip, 2ip when viewed through the packaging material from the outside can be evaluated as follows. First, a 3199 lumen LED light bulb is placed 3 m from the floor in a space of 1 tatami mat size. Next, the individually packaged packages (samples) of the incontinence pants 1 and napkin 2 are placed on the floor and light is irradiated from the LED light bulb. In this state, five random evaluators visually inspect the samples, and a sensory evaluation test is conducted. If, as a result of the sensory evaluation test, three or more of the five evaluators evaluate the designs to be the same, it is determined that the designs visually recognized when viewed through the incontinence pants 1 and napkin 2 from the outside are similar.

[0144] In addition, it is preferable that the non-skin-side sheet 21 constituting the most non-skin-side surface of the first waistline member 20 in the incontinence pants 1 and the non-skin-side sheet 121 constituting the most non-skin-side surface of the second waistline member 120 in the napkin 2 are made of the same material. As described above, in this embodiment, the first waistline member 20 of the incontinence pants 1 and the second waistline member 120 of the napkin 2 have the same external shape (horizontal lengths W1, W2, and vertical lengths L20we, L120we). In addition, by making the sheet members (21, 121) constituting the exteriors of the incontinence pants 1 and the napkin 2 the same material, it becomes difficult to distinguish the waistline members 20, 120, and it becomes difficult for a third party to distinguish between the pants-type absorbent articles when visually inspecting them. Therefore, it is possible to make it difficult to distinguish the types of pants-type absorbent articles from the outside.

[0145] On the other hand, the non-skin side sheet 21 constituting the most non-skin side surface of the first waistline member 20 in the incontinence pants 1 and the non-skin side sheet 121 constituting the most non-skin side surface of the second waistline member 120 in the napkin 2 may be made of different materials. For example, the non-skin side sheet 21 of the incontinence pants 1 may be made of a spunbond nonwoven fabric, and the non-skin side sheet 121 of the napkin 2 may be made of a spunbond nonwoven fabric. Even if the product is made of SMS nonwoven fabric, a third party cannot tell the difference between the two materials at a glance. In contrast, users can distinguish between the two by the difference in texture, such as touch. Therefore, by using different materials for both, the pants-type absorbent article The type can be made difficult for third parties to understand, but easy for the user to identify.

[0146] In addition, the design of the surface of the first waistband member 20 closest to the skin of the incontinence pants 1 and the napkin In the second waistband member 120, the design of the surface closest to the skin may be different from that of the second waistband member 120. For example, the color of the skin side sheets 22, 23 of the first waistband member 20 and the color of the skin side sheets 22, 23 of the second waistband member 120 may be different. It is preferable that the sheets 122 and 123 are different in color. The skin side of the material 20, 120 is visible only to the user in normal use. This is the part that is difficult for a third party to see. Therefore, it is important to make the design of the two different. This makes it easy for users to distinguish between the types of pants-type absorbent articles, and makes it difficult for third parties to distinguish between the two. This can make it more difficult to do so.

[0147] Similarly, in the incontinence pants 1, the design of the surface closest to the skin of the first absorbent body 10 and the napkin In the kin 2, the design of the surface of the second absorbent body 110 closest to the skin may be made different. For example, the color of the top sheet 12 of the first absorbent body 10 and the color of the top sheet 130 of the second absorbent body 110 may be different. It is preferable that the color of the sheet 112 is different from that of the absorbent body 10 of the pants-type absorbent article. The skin side of 110 is the part that is only visible to the user in normal use. Therefore, by making the design of both the logo and the logo different, Therefore, it is easy for users to distinguish the types of pants-type absorbent articles, and it is difficult for third parties to distinguish between the two. It is possible.

[0148] Furthermore, the first absorbent body 10 of the incontinence pants 1 and the second absorbent body 110 of the napkin 2 may be made to have different thicknesses in their natural state. The difference in thickness between the absorbent bodies 10, 110 is difficult for a third party to notice when visually inspecting from the outside, whereas a user (user) can easily recognize the difference between the two by touch, etc. Therefore, by making the thicknesses of the absorbent bodies 10, 110 different, it is possible for a user to easily distinguish between the types of pants-type absorbent articles, while making it difficult for a third party to distinguish between the two.

[0149] Here, the "natural state" refers to the state when pants-type absorbent articles (incontinence pants 1 or napkin 2) are left for a predetermined time. For example, after the finished incontinence pants 1 are taken out of the package, the first waist member 20 is pulled outward in both left and right directions (horizontal direction) to put the first waist member 20 in an "extended state." After this extended state is continued for 15 seconds, the incontinence pants 1 are released and placed on a flat surface such as a desk. The state after 5 minutes of being placed flat in this manner is regarded as the natural state.

[0150] The thickness of the absorbent main body 10, 110 can be compared by visual comparison, or by using a dial thickness gauge ID-C1012C manufactured by Mitutoyo Corporation or an equivalent device to obtain and compare values ​​measured by applying pressure to the target area at, for example, 3.0 gf / cm2. In this case, the side joint portions 20we, 120we may be peeled off to lay the pants-type absorbent article out, and then the thickness may be measured.

[0151] Also, the thickness of the individually packaged incontinence pants 1 (individually packaged body 1ip) and the thickness of the individually packaged napkin 2 (individually packaged body 2ip) may be different. The difference in thickness between the individual packages 1ip, 2ip is difficult for a third party to notice just by looking, whereas a user (user) can easily recognize the difference between the two by the feel when actually holding them. Therefore, by making the thicknesses of the individual packages 1ip, 2ip different, it is possible for the user to easily distinguish the types of pants-type absorbent articles, while making it difficult for a third party to distinguish between the two. The thickness of the individual packages can be measured by the same means as that used to measure the thickness of the absorbent main body 10 described above.

[0152] In addition, the weight of the first absorbent body 10 of the incontinence pants 1 in an unused state may be different from the weight of the second absorbent body 110 of the napkin 2 in an unused state. The difference in weight between the absorbent bodies 10, 110 is difficult for a third party to notice just by looking at them, whereas a user (user) can easily recognize the difference between the two by the difference in weight when holding them during use. Therefore, by making the weights of the absorbent bodies 10, 110 different, it is possible for a user to easily distinguish the types of pants-type absorbent articles, while making it difficult for a third party to distinguish between the two. The weights of the absorbent bodies 10, 110 can be measured using an electronic balance or the like after separating the absorbent bodies 10, 110 in an unused state from the waistline members 20, 120.

[0153] Furthermore, the rigidity of the first absorbent body 10 of the incontinence pants 1 and the rigidity of the second absorbent body 110 of the napkin 2 may be different. The difference in rigidity between the absorbent bodies 10, 110 is difficult for a third party to notice just by looking, whereas a user (user) can easily recognize the difference between the two by the feel when holding them during use. Therefore, by making the rigidities of the individual absorbent bodies 10, 110 different, it is possible for a user to easily distinguish between the types of pants-type absorbent articles, while making it difficult for a third party to distinguish between the two.

[0154] The rigidity of the absorbent body 10, 110 can be measured as a bending rigidity value based on, for example, "Standardization and Analysis of Texture Evaluation," 2nd Edition (published by the Texture Measurement and Standardization Research Committee of the Textile Machinery Society of Japan, July 10, 1980). Regarding the measurement method for each mechanical property, only the measurement conditions related to this measurement are described below. The bending properties were measured using a KES-FB2 manufactured by Kato Tech Co., Ltd., by fixing a 1 cm width of a specified area of ​​each sample (absorbent body) between chucks spaced 1 cm apart as a sample, bending it to a maximum curvature of +2.5 cm-1 on the front side, then bending it to a maximum curvature of -2.5 cm-1 on the back side, and then returning it to its original state. The sample was measured in a vertical position to reduce the effect of gravity, and the bending rigidity B [gf·cm2 / cm] was calculated from the slope when the slope of the bending moment with respect to the curvature became almost constant after starting to bend it to the front side. The bending stiffness B was measured in the longitudinal direction at a portion of the absorbent body where the absorbent body was thickest (in this product, the transverse center portion of the longitudinal center position CL).

[0155] Furthermore, the number of pants-type absorbent articles contained in the unopened container 1pkg of incontinence pants 1 and the number of pants-type absorbent articles contained in the unopened container 2pkg of napkins 2 may be different. If the number of incontinence pants 1 and napkins 2 contained in a package differs, it is difficult for a third party who is not planning to purchase the product to visually distinguish whether the package contains incontinence pants 1 or napkins 2 at a store or the like. On the other hand, a user who is planning to purchase the product can easily distinguish between the two based on the difference in the number of products contained. Therefore, it is easy for the user to distinguish between the types of pants-type absorbent articles, and it is difficult for a third party to distinguish between the two.

[0156] Also, the shape of the leg openings 1b in the incontinence pants 1 in the stretched state may be different from the shape of the leg openings 2b in the napkin 2 in the stretched state. Specifically, the shape of the outer edge 1be of the leg openings in the incontinence pants 1 in the stretched state and the length along the outer edge 1be of the leg openings (see FIG. 2) may be different from the shape of the outer edge 2be of the leg openings in the napkin 2 in the stretched state and the length along the outer edge 2be of the leg openings (see FIG. 6). Even if the outer edges of the leg openings of the incontinence pants 1 and the napkin 2 are different in length and shape, it is difficult for a third party to tell the difference between them just by visually checking, whereas a user (user) can easily recognize that the sizes and shapes of the leg openings 1b, 2b are different when the leg openings are opened during the action of putting on the pants-type absorbent article, etc. Therefore, it is easy for a user to distinguish the types of pants-type absorbent articles, and it is difficult for a third party to distinguish between the two.

[0157] In addition, the second absorbent body 110 of the napkin 2 has a high density portion 140 (second linear compressed portion). The first absorbent body 10 of the incontinence pants 1 is provided with a high compression line corresponding to the second compression line. The density portion 40 (first compressed line portion) may not be provided. A certain napkin 2 is designed to prevent menstrual blood from leaking through the skin by attaching it to the crotch area ( Since it is necessary to make close contact with the vagina or other excretory opening, a high density portion 140 (linear compression portion) is provided. This allows the material to bend and deform, making it easier to fit to the user's body shape. On the other hand, incontinence pants1, which are urine care products, are used to prevent rewetting, etc. Therefore, it is desirable to form a small gap (space) between the user (wearer) and the body. Therefore, compared with the napkin 2, the crotch area is not necessarily required to be tightly fitted. It is not necessary to provide a high density portion 40 (linear compressed portion) to make the structure easily deformable. The linear compression portions provided on the main body 10, 110 are, when viewed from the outside of the pants-type absorbent article, This is visible only to the user and is difficult for third parties to see. The function of the pants-type absorbent article is improved while the user can easily identify the type of pants-type absorbent article. This makes it difficult for a third party to distinguish between the two.

[0158] In addition, the first absorbent body 10 of the incontinence pants 1 is provided with a high density portion 40 (first linear compressed portion). In this case, the depth of the high density portion 40 (the amount of compression in the thickness direction) and the 2. The depth (in the thickness direction) of the high density portion 140 (linear compressed portion) provided in the absorbent body 110 For example, in the incontinence pants 1, the first compressed line portion is shallow. In the napkin 2, the second compressed line portion is formed deeper. The first absorbent body 10 of the napkin 1 is prevented from being excessively deformed, and the second absorbent body 10 of the napkin 2 is prevented from being excessively deformed. The absorbent body 110 is easily bent and deformed, and does not fit the crotch area of ​​the user. And the difference in the depth of the linear compression part is determined by the user. Therefore, depending on the presence or absence of compressed lines, it is easy for the user to distinguish between the types of pants-type absorbent articles, while making it difficult for third parties to distinguish between the two.

[0159] Also, the second absorbent body 110 of the napkin 2 may be provided with an absorbent body elastic member 150 (hereinafter referred to as the second absorbent body elastic member), and the first absorbent body 10 of the incontinence pants 1 may not be provided with an absorbent body elastic member 50 (hereinafter referred to as the first absorbent body elastic member) corresponding to the second absorbent body elastic member. As described above, the napkin 2, which is a sanitary product, needs to be tightly fitted to the crotch area of ​​the user. For this reason, it is desirable to provide the absorbent body elastic member 150 (second absorbent body elastic member) so that the second absorbent body 110 is pressed against the crotch area of ​​the user by the elasticity exhibited by the second absorbent body elastic member 150 when the napkin 2 is worn. On the other hand, in the incontinence pants 1, which are a urine care product, the first absorbent body elastic member 50 is not provided, so that a gap can be easily formed between the first absorbent body 10 and the skin of the user. The absorbent body elastic member provided in the absorbent bodies 10, 110 is easily visible to the user, but is difficult to be seen by a third party. This improves the functionality of the pants-type absorbent article, while making it easier for the user to distinguish between the types of pants-type absorbent article and making it difficult for third parties to distinguish between the two.

[0160] In addition, when the first absorbent body 10 of the incontinence pants 1 is provided with an absorber elastic member 50 (first absorber elastic member), the stress of the absorber elastic member 50 and the stress of the absorber elastic member 150 provided on the second absorbent body 110 of the napkin 2 may be made different from each other. In other words, the magnitude of the force acting when the absorber elastic members 50, 150 are stretched by a unit length (the force required to stretch by a unit length) may be made different. For example, the stress of the second absorber elastic member 150 provided on the napkin 2 may be made larger than the stress of the first absorber elastic member 50 provided on the incontinence pants 1. In this way, when worn, the first absorbent body 10 of the incontinence pants 1 is likely to form a gap between itself and the skin of the user, and the second absorbent body 110 of the napkin 2 is likely to be pressed against the crotch portion of the user and fit easily to the crotch portion. Such a difference in stress between the absorbent body elastic members 50, 150 can be recognized by a user who actually wears the absorbent body, but cannot be recognized by third parties. Therefore, the difference in stress between the absorbent body elastic members 50, 150 makes it easy for a user to distinguish between the types of pants-type absorbent articles, while making it difficult for third parties to distinguish between the two.

[0161] In addition, it is preferable that the joining pattern of the pair of first side joining portions 20we, 20we provided at both ends in the left-right direction of the first waistband member 20 of the incontinence pants 1 is different from the joining pattern of the pair of second side joining portions 120we, 120we provided at both ends in the left-right direction of the second waistband member 120 of the napkin 2. For example, when the side joining portions are formed by a known welding means, one side joining portion has a pattern in which dot-shaped welding portions are arranged in a lattice pattern, and the other side joining portion has a pattern in which linear welding portions along the left-right direction are arranged intermittently at intervals in the up-down direction (both are not shown). Such a difference in the joining patterns of the side joining portions can be identified by a user (user) who can see it from close up, but is difficult to identify by a third party. Therefore, the difference in the joining patterns of the side joining portions makes it easy for the user to identify the type of pants-type absorbent article, and makes it difficult for a third party to distinguish between the two.

[0162] On the other hand, the joining pattern of the pair of first side joining parts 20we, 20we provided at both left and right ends of the first waistline member 20 of the incontinence pants 1 may be the same as the joining pattern of the pair of second side joining parts 120we, 120we provided at both left and right ends of the second waistline member 120 of the napkin 2. In this case, the external shapes of the incontinence pants 1 and the napkin 2 become closer, making it more difficult for a third party to distinguish between them. However, since the user (user) himself / herself will not be able to distinguish between them based on the joining patterns of the side joining parts 20we, 20we, it is necessary to make it possible to distinguish between the incontinence pants 1 and the napkin 2 in advance by checking the difference in the product names 212, 222 displayed on the product packages (containers 1pkg, 2pkg) and other differences in configuration.

[0163] Also, the incontinence pants 1 may have a post-treatment tape 70 on the non-skin side of the first rear waistband portion 20b, and the napkin 2 may have no post-treatment tape 170 on the non-skin side of the second rear waistband portion 120b. As described above, the post-treatment tape is used when the pants-type absorbent article is rolled up and disposed of after use, and is provided to prevent excrement adhering to the absorbent body from leaking outward. Therefore, it is desirable that the incontinence pants 1, which need to prevent leakage of urine, etc., have the post-treatment tape 70. On the other hand, the napkin 2 does not necessarily have to have the post-treatment tape 170, since menstrual blood has a high viscosity and is unlikely to leak. In this embodiment, both the incontinence pants 1 and the napkin 2 are folded as described in FIG. 8 and distributed to the market as individual packages 1ip, 2ip packaged in packaging materials 81, 82. In addition, in the folded and individually packaged state, the post-processing tapes 70, 170 cannot be seen from the outside (see Figs. 8A and 8B). Therefore, depending on the presence or absence of the post-processing tapes 70, 170, the user can easily distinguish the type of pants-type absorbent article, while making it difficult for a third party to distinguish between the two.

[0164] Furthermore, in this embodiment, the brand name 211 displayed on the package of the incontinence pants 1 (container 1 pkg) and the brand name 221 displayed on the package of the napkin 2 (container 2 pkg) are the same brand name. Since the same brand name is attached to the packages of the urinary care product and the sanitary product, it becomes difficult for a third party to know the type of pants-type absorbent article that a user (purchaser) is about to purchase at a store, etc. This reduces the psychological burden on the user.

[0165] In addition, it is desirable that the size of the first packaging material 81 for packaging the folded incontinence pants 1 and the size of the second packaging material 82 for packaging the folded napkin 2 are the same. In this embodiment, the outer dimensions (W1 and W2, and L20 and L21) of the incontinence pants 1 and the napkin 2 are the same. The dimensions are the same (120we) and the way they are folded and wrapped is also the same (see Figures 8 and 9). Therefore, by making the size of the first packaging material 81 and the size of the second packaging material 82 equal, 1 individually packaged incontinence pants (individually packaged 1ip) and 2 individually packaged napkins (individually packaged 2ip) ip) will be the same size. Therefore, it will be difficult for a third party to distinguish between the two. Cut.

[0166] <Modification> The waist member 20 (first waist member) of the incontinence pants 1 can be deformed as follows. FIG. 15 is a schematic perspective view of the light incontinence pants 1 according to the modified example. FIG. 2 is a schematic cross-sectional view showing a cross-sectional state of the light incontinence pants 1 in a stretched state in the thickness direction. This is a figure corresponding to 3.

[0167] As shown in FIG. 16, the front waistline portion 20f of the first waistline member 20 of the modified example has At the top end 20ef in the vertical direction (the front end in the longitudinal direction), the non-skin side sheet 21 is A folded-back portion 60 is formed by folding back the garment from the side toward the non-skin side. Between the non-skin side sheet 21 and the non-skin side sheet 21 in the thickness direction, a waist circumference elastic member 25 such as rubber thread is provided in the left and right direction. The folded-back portion 60 is formed by applying a coating to the outer peripheral surface of the waist elastic member 25. The area is bonded to the non-skin side sheet 21 via an adhesive such as a hot melt adhesive applied thereto. and a folded non-joined portion 62 that is not joined to the non-skin side sheet 21. It has.

[0168] The folded-back non-joined portion 62 of the folded-back portion 60 is connected to the first waistband member 20 (the front waistband 15, the fold-back non-jointed portion 62 is deformed to form large pleats. This allows the incontinence pants 1 to have an appearance as if they are provided with frills around the waist opening 1a. For example, when the first waist member 20 contracts in the left-right direction while the fold-back joint portion 61 contracts in the left-right direction, the fold-back non-jointed portion 62 does not contract easily in the left-right direction, so that the fold-back non-jointed portion 62 deforms to form large pleats. This gives the incontinence pants 1 an appearance as if they are provided with frills around the waist opening 1a, as shown in FIG.

[0169] By forming beautiful frills in a conspicuous location at the upper end of the front waistband portion 20f, a third party who sees the frills will assume that the incontinence pants 1 are not a urine care product but rather a napkin, underwear, or the like. Therefore, it is possible to make it difficult to tell the type of incontinence pants 1.

[0170] Such frills may be provided on the rear waistline portion 20b of the first waistline member 20. Moreover, the second waistline member 120 of the napkin 2 may also be provided with similar frills.

[0171] ===Other=== The above embodiment is for the purpose of facilitating understanding of the present invention, and is not intended to limit the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit of the present invention, and that the present invention includes equivalents thereof.

[0172] In the above embodiment, the skin side sheets 22, 23 of the first waistline member 20 are made of stretch sheets (stretch nonwoven fabrics) to impart stretchability in the left-right direction to the first waistline member 20, but stretchability may be imparted to the first waistline member 20 by using an elastic member other than a stretch sheet. For example, stretchability may be imparted to the waistline member 20 by providing a plurality of linear elastic members 26 such as rubber thread as described below.

[0173] Fig. 17 is a plan view of incontinence pants 1 equipped with linear elastic members 26 in an unfolded and stretched state, and corresponds to Fig. 2. The first waistband member 20 shown in Fig. 17 is provided with skin-side sheets 27, 28 on the skin side in the thickness direction of the non-skin-side sheet 21. The skin-side sheets 27, 28 are members corresponding to the skin-side sheets 22, 23, respectively, but unlike the skin-side sheets 22, 23, they are formed of nonwoven fabric that does not have elasticity (or has extremely low elasticity). Specifically, they are nonwoven fabrics composed of components such as PP (polypropylene), PE (polyethylene), and PET (polyethylene terephthalate), and do not contain elastic components such as urethane.

[0174] The linear elastic members 26 are joined between the non-skin side sheet 21 and the skin side sheets 27, 28 in a state stretched in the left-right direction, and a plurality of them are provided at predetermined intervals in the up-down direction. The stretchability exhibited by the linear elastic members 26 imparts stretchability in the left-right direction to the first waistline member 20. The configuration other than the linear elastic members 26 and the skin side sheets 27, 28 is the same as the configuration of the incontinence pants 1 described with reference to Fig. 1 etc.

[0175] A similar linear elastic member may also be provided in the second waist member 120 of the napkin 2. Alternatively, one of the first waist member 20 of the incontinence pants 1 and the second waist member 120 of the napkin 2 may be provided with a linear elastic member and the other may not be provided with a linear elastic member.
