[0005] Patent Document 1: Japanese Patent Application Publication No. 2023-20427 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] From the perspectives of reducing logistics costs for packaging materials, minimizing display and storage space, and alleviating discomfort when wearing diapers, it is preferable to make diapers thinner, especially to reduce the thickness of the crotch area where the absorbent core is located. However, there is a concern that diaper wearers, or those attempting to put diapers on them, may not be able to perceive the thinner thickness of the crotch area.

[0008] The present invention was made in view of the above-mentioned problems, and its purpose is to make it easy for users to actually feel that the crotch of the shorts-type absorbent item is thinner.

[0009] Solution for solving the problem

[0010] The main invention for achieving the above-mentioned objective is a packaging body for a shorts-type absorbent article, comprising three or more shorts-type absorbent articles adjacent to each other, and a storage member for storing the shorts-type absorbent articles. The invention is characterized in that the central shorts-type absorbent article among the three or more shorts-type absorbent articles has vertical, horizontal, and front-back directions, and has a crotch portion and a pair of waist portions. The crotch portion has an absorbent core comprising pulp fibers and a highly absorbent polymer. The two sides of each pair of waist portions in the horizontal direction are joined by a pair of joints, allowing storage in a folded state where the waist portions are folded back at the left-right folds along the horizontal direction and at the vertical folds along the vertical direction. In the folded state, the pair of waist portions have a folded-back portion on one side in the left-right direction that is folded back at the upper-lower fold, a folded-back portion on the other side in the left-right direction that is folded back at the upper-lower fold, and a non-folded-back portion that is not folded back at the upper-lower fold. When the central shorts-type absorbent item is removed from the packaging of the shorts-type absorbent item and the left-right fold is unfolded after 30 seconds, the average thickness of the center of the crotch portion in the left-right direction is less than the average of the sum of the thickness of the folded-back portion and the thickness of the non-folded-back portion along a straight line along the left-right direction passing through the center of the upper-lower direction of the joint. The average thickness of the center of the crotch portion in the left-right direction is less than 8 mm.

[0011] Additionally, a packaging assembly for a shorts-type absorbent item is characterized in that the packaging assembly comprises a first shorts-type absorbent item packaging body and a second shorts-type absorbent item packaging body. The first shorts-type absorbent item packaging body includes a first shorts-type absorbent item and a first storage member that stores three or more of the first shorts-type absorbent items adjacent to each other and displays a predetermined brand name. The second shorts-type absorbent item packaging body includes a second shorts-type absorbent item and a second shorts-type absorbent item that stores three or more of the second shorts-type absorbent items adjacent to each other. The second storage component displaying the predetermined brand name, for the central first shorts-type absorbent item among the three or more first shorts-type absorbent items, and the central second shorts-type absorbent item among the three or more second shorts-type absorbent items, respectively, has a crotch portion and a pair of waist portions in the up-down, left-right, and front-back directions. The crotch portion has an absorbent core composed of pulp fiber and a highly absorbent polymer. The left-right sides of each of the pair of waist portions are joined by a pair of joints to extend along the left-right direction. The right fold is folded back, and the pair of waist sections are folded back along the vertical direction at the vertical fold. In this folded state, the pair of waist sections have a folded-back portion on one side of the left and right direction that is folded back at the vertical fold, a folded-back portion on the other side of the left and right direction that is folded back at the vertical fold, and a non-folded-back portion that is not folded back at the vertical fold. After the first shorts-type absorbent item is removed from its packaging and 30 seconds have elapsed, the left and right folds are unfolded. Below, the average thickness of the center of the crotch portion in the left-right direction is less than the average of the sum of the thickness of the folded portion and the thickness of the non-folded portion along the straight line along the left-right direction passing through the center of the joint portion in the up-down direction, and the average thickness of the center of the crotch portion in the left-right direction is less than 8mm. When the second shorts-type absorbent item is taken out of the packaging and the left and right folded portions are folded back and unfolded after 30 seconds, the average thickness of the center of the crotch portion in the left-right direction is greater than 8mm.

[0032] Based on the description in this specification and the accompanying drawings, at least the following matters become clear.

[0033] (Method 1)

[0034] A packaging body for a shorts-type absorbent item comprises three or more shorts-type absorbent items adjacent to each other, and a storage member for storing the shorts-type absorbent items. The shorts-type absorbent item, being the central one among the three or more shorts-type absorbent items, has a crotch portion and a pair of waist portions in the vertical, horizontal, and front-back directions. The crotch portion has an absorbent core composed of pulp fibers and a highly absorbent polymer. The two sides of each pair of waist portions in the horizontal direction are joined by a pair of joints to store the item in a folded state where they are folded back at left-right folds along the horizontal direction and at vertical folds along the vertical direction. The pair of waist portions have a folded-back portion on one side in the left-right direction that is folded back at the up-down fold, a folded-back portion on the other side in the left-right direction that is folded back at the up-down fold, and a non-folded-back portion that is not folded back at the up-down fold. When the central shorts-type absorbent item is removed from the packaging of the shorts-type absorbent item and the left-right fold is unfolded after 30 seconds, the average thickness of the center of the crotch portion in the left-right direction is less than the average of the sum of the thickness of the folded-back portion and the thickness of the non-folded-back portion along a straight line along the left-right direction passing through the center of the up-down direction of the joint. The average thickness of the center of the crotch portion in the left-right direction is less than 8 mm.

[0035] According to Method 1, regarding the shorts-type absorbent item taken out of the packaging, the average thickness of the crotch portion at the center in the left-right direction is less than 8mm, and is less than the average of the sum of the thickness of the folded portion and the non-folded portion along the straight line in the left-right direction passing through the center of the joint. Therefore, compared to the case where the average thickness of the crotch portion at the center in the left-right direction is greater than 8mm, and greater than the average of the sum of the thickness of the folded portion and the non-folded portion along the straight line in the left-right direction passing through the center of the joint, it is easier for users of the shorts-type absorbent item to actually feel that the crotch portion of the shorts-type absorbent item is thinner when taking it out of the packaging.

[0036] (Method 2)

[0037] In the packaging of the shorts-type absorbent article described in Method 1, for at least one of the pair of waist portions, the pair of sheet portions are bonded together by an adhesive, and there is a non-bonded area without the adhesive for a predetermined length from the upper end of the waist portion in the vertical direction.

[0038] According to the packaging of the shorts-type absorbent item of method 2, the non-adhesive area in the waist is softer and more prone to thickening than the area with adhesive. Therefore, it is easy to make the difference between the thickness of the folded part and the thickness of the non-folded part relative to the thickness of the crotch part larger, which makes it easy for users to feel that the thickness of the crotch part is thinner.

[0039] (Method 3)

[0040] In the packaging of the shorts-type absorbent article described in Method 2, when the shorts-type absorbent article in the folded state is unfolded with the folded portion on one side and the folded portion on the other side unfolded, when viewed along the front-back direction, the folded portion has a portion that overlaps with the non-adhesive area.

[0041] According to the packaging of the shorts-type absorbent item of method 3, it is easy to make the difference between the sum of the thickness of the folded part and the thickness of the non-folded part and the thickness of the crotch part larger, which makes it easy for users to feel that the thickness of the crotch part is thinner.

[0042] (Method 4)

[0043] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 3, for at least one of the pair of waist portions, there is an upper region that is above the center in the vertical direction of the joint and a lower region that is below the center in the vertical direction of the joint, wherein the force per unit length in the vertical direction for extending the upper region by a predetermined length in the horizontal direction is greater than the force per unit length in the vertical direction for extending the lower region by a predetermined length in the horizontal direction.

[0044] According to the packaging of the shorts-type absorbent item of method 4, the upper area is more prone to shrinkage than the lower area. As a result, the upper part of the waist section is more prone to thickening, which makes it easier to increase the difference between the thickness of the folded-back part and the thickness of the non-folded-back part relative to the thickness of the crotch section. This makes it easier for users to feel that the thickness of the crotch section is thinner.

[0045] (Method 5)

[0046] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 4, for at least one of the pair of waist portions, there are a pair of sheet portions and a plurality of elastic bands fixed between the pair of sheet portions. The plurality of elastic bands extend and contract in the left-right direction and have an upper region that is above the center of the vertical direction of the joint and a lower region that is below the center of the vertical direction of the joint. The spacing between adjacent elastic bands in the vertical direction in the upper region is shorter than the spacing between adjacent elastic bands in the vertical direction in the lower region.

[0047] According to the packaging of the shorts-type absorbent item of method 5, the upper area is more prone to shrinkage than the lower area. As a result, the upper part of the waist section is more prone to thickening, which makes it easier to increase the difference between the thickness of the folded-back section and the thickness of the non-folded-back section relative to the thickness of the crotch section. This makes it easier for users to feel that the thickness of the crotch section is thinner.

[0048] (Method 6)

[0049] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 5, the folded state is such that the shorts-type absorbent article is folded back in one direction in the front-back direction at the left and right folds, and the pair of waist sections are folded back in the other direction in the front-back direction at the up and down folds.

[0050] According to the packaging of the shorts-type absorbent item of method 6, when viewed from the side opposite to the left and right folds in the vertical direction of the folded state, it is easy to identify the boundary between the absorbent item and the waist. Therefore, it is easy to make the difference between the thickness of the folded part and the thickness of the non-folded part on one side greater than the thickness of the crotch part, which makes it easy for users to feel that the thickness of the crotch part is thinner.

[0051] (Method 7)

[0052] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 6, in the folded state, the one-sided fold-back portion and the other-sided fold-back portion are separated in the left-right direction.

[0053] According to the packaging of the shorts-type absorbent item according to method 7, when the packaging is in a folded state and the folded-back portion on one side is separated in the left and right direction, when the shorts-type absorbent item is taken out of the packaging, it is easy for the user to actually feel that the crotch area of ​​the shorts-type absorbent item is thinner.

[0054] (Method 8)

[0055] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 6, in the folded state, the folded portion on one side and the folded portion on the other side have overlapping portions in the left-right direction.

[0056] According to the packaging of the shorts-type absorbent item of method 8, in the folded state, one side fold and the other side fold have overlapping portions in the left and right directions. In this case, when the shorts-type absorbent item is taken out of the packaging, it is easy for the user to actually feel that the crotch of the shorts-type absorbent item is thinner.

[0057] (Method 9)

[0058] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 3, the pair of waist sections are composed of one waist section and another waist section, and each has a telescopic member that can extend and retract in the left and right directions, and the color of the telescopic member of the one waist section is different from the color of the telescopic member of the other waist section.

[0059] The packaging of the shorts-type absorbent item according to method 9 makes it easy for users to identify the front and back orientation of the shorts-type absorbent item.

[0060] (Method 10)

[0061] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 9, when the central shorts-type absorbent article is removed from the packaging of the shorts-type absorbent article and the left and right folds are folded back after 30 seconds, the average thickness of the center of the crotch portion in the left and right direction is less than the average thickness of the non-folded portion along the straight line in the left and right direction passing through the center of the joint portion in the up and down direction.

[0062] According to the packaging of the shorts-type absorbent item of method 10, when the shorts-type absorbent item is taken out of the packaging, compared to the case where the average thickness of the center of the crotch in the left-right direction is greater than the average thickness of the non-folded portion along the straight line in the left-right direction passing through the center of the joint, it is easier for the user of the shorts-type absorbent item to actually feel that the thickness of the crotch of the shorts-type absorbent item is thinner.

[0063] (Method 11)

[0064] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 10, in the folded state after the central shorts-type absorbent article is removed from the packaging of the shorts-type absorbent article and 30 seconds have passed, the length in the vertical direction from the outer end of the left and right folds to the upper end of the waist portion is longer than the length in the vertical direction from the outer end of the left and right folds to the lower end of the crotch portion.

[0065] According to the packaging of the shorts-type absorbent item of method 11, when the shorts-type absorbent item is taken out of the packaging, it is easy for the user to actually feel that the crotch area of ​​the shorts-type absorbent item is thinner.

[0066] (Method 12)

[0067] In the packaging of the shorts-type absorbent article described in any of the methods 1 to 11, the crotch portion has an absorbent body having the absorbent core. In the folded state after the central shorts-type absorbent article is removed from the packaging of the shorts-type absorbent article and 30 seconds have passed, when viewed from one side in the front-back direction, the absolute value of the difference between the average thickness of the crotch portion where the absorbent body and the pair of waist portions overlap and the average thickness of the crotch portion where the absorbent body and the pair of waist portions do not overlap is greater than the thickness of the non-folded portion along the straight line in the left-right direction at the center in the vertical direction passing through the joint.

[0068] According to the packaging of the shorts-type absorbent item of method 12, when the shorts-type absorbent item is taken out of the packaging, it is easy for the user to actually feel that the crotch area of ​​the shorts-type absorbent item is thinner.

The second storage component, representing the predetermined brand name, for the central first shorts-type absorbent item among the three or more first shorts-type absorbent items, and the central second shorts-type absorbent item among the three or more second shorts-type absorbent items, respectively, has a crotch portion and a pair of waist portions in the up-down, left-right, and front-back directions. The crotch portion has an absorbent core composed of pulp fibers and a highly absorbent polymer. The two sides of each pair of waist portions in the left-right direction are joined by a pair of joints to ensure that the left and right sides are aligned along the left-right direction. The folded portion is folded back, and the pair of waist sections are folded back at the vertical folded portion along the vertical direction for storage. In this folded state, the pair of waist sections have a folded-back portion on one side of the left and right direction that is folded back at the vertical folded portion, a folded-back portion on the other side of the left and right direction that is folded back at the vertical folded portion, and a non-folded-back portion that is not folded back at the vertical folded portion. After the first shorts-type absorbent item is removed from the packaging and the left and right folded portions are unfolded after 30 seconds, the folded-back portion is returned to its original position. Below, the average thickness of the center of the crotch portion in the left-right direction is less than the average of the sum of the thickness of the folded portion and the thickness of the non-folded portion along the straight line along the left-right direction passing through the center of the joint portion in the up-down direction, and the average thickness of the center of the crotch portion in the left-right direction is less than 8mm.

[0089] ===Implementation Methods===

[0090] <<Packaging for shorts-type absorbent items 100>>

[0091] Hereinafter, as an example of the packaging of the shorts-type absorbent article of this embodiment, the packaging 100 of the shorts-type disposable diaper (hereinafter also referred to as "packaging 100") will be described.

[0092] Figure 1 This is a perspective view of the packaging body 100. The packaging body 100 includes a short-length disposable diaper 1 (hereinafter also referred to as "diaper 1") that serves as three or more short-length absorbent items, and a storage member 101 for storing multiple (three or more) diapers 1. The diapers 1 are circulated in a state where they are stored in the storage member 101 (hereinafter also referred to as "the stored state"), thus ensuring hygiene. Hereinafter, the wearer of the diaper 1, the person who puts the diaper 1 on the wearer, or the person who handles the packaging body 100 will be referred to as "user, etc."

[0093] <<Basic Structure of Shorts-Type Disposable Diapers 1>>

[0094] Figure 2 This is a rough 3D diagram of Diaper 1. Figure 3 This is a rough top view of the diaper 1 as it is unfolded and stretched, viewed from the side of the wearer's skin. Figure 4 yes Figure 3 A schematic cross-sectional view at point AA. In this embodiment, an adult shorts-type disposable diaper 1 is exemplified as the shorts-type absorbent article housed in the storage member 101, but it is not limited thereto. For example, the shorts-type absorbent article may also be a children's shorts-type disposable diaper, a shorts-type sanitary napkin, etc.

[0095] Diaper 1 is a product for single excretion or a product suitable for use in combination with absorbent pads. In addition, diaper 1 is not limited to a product for single excretion or a product for use in combination with absorbent pads, etc., but can also be a product for multiple excretions (2 to 3 times, etc.), or an absorbent item that can be used alone without being used in combination with absorbent pads, etc.

[0096] The unfolded state of diaper 1 refers to a state in which the pair of joints SS on both sides of the diaper 1 in its shorts-type state are separated, allowing the diaper 1 to be opened and unfolded flat. The stretched state of diaper 1 refers to a state in which the elastic members of the diaper 1 are stretched to the point that the folds of the diaper 1 are no longer visually discernible. Specifically, it refers to a state in which the dimensions of each component constituting the diaper 1 are consistent with or close to the dimensions of the individual component (i.e., the dimensions in a state where the elasticity of the elastic member is not apparent).

[0097] like Figure 2As shown, diaper 1, in its shorts-style configuration, has vertical, horizontal, and front-back directions, and features a waist opening BH and a pair of leg openings LH. Additionally, as... Figure 3 , Figure 4 As shown, diaper 1 has a length direction, a left-right direction, and a thickness direction when unfolded. In the shorts-style configuration, the up-down direction corresponds to the length direction when unfolded. In the thickness direction, the side that contacts the wearer's skin when worn is called the skin side, and the opposite side is called the non-skin side. Furthermore, in the front-back direction and the length direction, the side that becomes the wearer's abdomen is called the front side / abdominal side, and the side that becomes the wearer's back is called the back side / back side. Additionally, in the up-down direction and the length direction, the side with the waist opening (BH) is called the upper side, and the opposite side is called the lower side.

[0098] The diaper 1 has an absorbent body 10 and an outer body 18. The outer body 18 has a pair of waist sections 20 and 30 and a crotch section 35 located under the wearer's crotch. The outer body 18 is attached to the non-skin-facing side of the absorbent body 10 by an adhesive or the like. The front waist section of the pair of waist sections 20 and 30 is referred to as the ventral waist section 20, and the rear waist section of the pair of waist sections 20 and 30 is referred to as the dorsal waist section 30. Figure 3 The diaper 1 in its unfolded state has its ventral waist section 20 and dorsal waist section 30 folded together, and the left and right sides of the ventral waist section 20 and the dorsal waist section 30 joined together to form a pair of side joints SS. Thus, the diaper 1 becomes Figure 2 The shorts type is shown. Examples of joining methods for the side joints SS include heat fusion, ultrasonic welding, and adhesive-based joining methods.

[0099] like Figure 4 As shown, the absorbent body 10 has an absorbent core 11, a liquid-permeable top sheet 12 disposed on the skin side of the absorbent core 11, a liquid-impermeable back sheet 13 disposed on the non-skin side of the absorbent core 11, and an outer cover sheet 14.

[0100] The absorbent core 11 is an absorbent core that absorbs and retains excreted liquid, formed by shaping liquid-absorbing raw materials such as pulp fiber and superabsorbent polymer (SAP) into a predetermined shape. Alternatively, the absorbent core 11 may also be covered by a liquid-permeable sheet (not shown) such as thin cotton paper or non-woven fabric.

[0101] The absorbent core 11 of diaper 1 is thinner than the absorbent core of conventional shorts-type disposable diapers (such as shorts-type disposable diaper 5 described later). The area weight of pulp fibers in the absorbent core 11 of diaper 1 is about half that of pulp fibers in conventional shorts-type disposable diapers, and the area weight of superabsorbent polymer (SAP) in the absorbent core 11 of diaper 1 is about one-third that of superabsorbent polymer (SAP) in conventional shorts-type disposable diapers.

[0102] Preferably, the absorbent core 11 has a pulp fiber weight per unit area of ​​150 g / m². 2 Preferably, the superabsorbent polymer (SAP) has a surface weight of 100 g / m². 2 Furthermore, it is preferable that the area weight of the pulp fiber in the absorbent core 11 is greater than that of the superabsorbent polymer (SAP), and more preferably, the area weight of the pulp fiber is twice that of the superabsorbent polymer (SAP). This reduces the possibility of excessive thickness in the absorbent core 11, provides sufficient absorption for excrement from a single excretion, and mitigates the increased stiffness and decreased skin feel caused by the superabsorbent polymer (SAP), thus maintaining the skin feel of the pulp fiber.

[0103] It could also be, such as Figure 3 As shown, elastic leg members 15 (e.g., elastic bands) that stretch and contract along the length of the absorbent body 10 are provided on both sides of the absorbent body 10 in the left-right direction. Alternatively, an elastic member that stretches and contracts along the length direction may be provided on the inner side of the elastic leg members 15 in the left-right direction, thereby providing a leak-proof wall that can stand upright towards the skin.

[0104] like Figure 3 and Figure 4 As shown, the outer body 18 has an outer top piece 21, a ventral outer back piece 22, and a dorsal outer back piece 32.

[0105] The outer top plate 21 is positioned from the abdominal side waist 20, passing through the crotch 35, to the back side waist 30. Figure 4 The width (length in the left-right direction) of the outer top plate 21 in the ventral waist section 20 and the dorsal waist section 30 is greater than the width (length in the left-right direction) of the outer top plate 21 in the crotch section 35. Figure 3 The outer top sheet 21 can be formed from hot-air nonwoven fabric, spunbond nonwoven fabric, SMS nonwoven fabric (spunbond / meltblown / spunbond nonwoven fabric), waterproof membrane, etc.

[0106] like Figure 3 and Figure 4As shown, the ventral outer back panel 22 is located on the non-skin side of the outer top panel 21, and the ventral waist portion 20 is formed by the ventral outer back panel 22 and the outer top panel 21. The outermost (upper) end of the ventral outer back panel 22 in the longitudinal direction is folded back towards the skin to form a folded portion 22r. The folded portion 22r covers one end (outer end) of the outer top panel 21 in the longitudinal direction. Alternatively, the outermost (upper) end of the ventral outer back panel 22 in the longitudinal direction may not be folded back.

[0107] Similarly, as Figure 3 and Figure 4 As shown, the back cover panel 32 is located on the non-skin side of the outer cover top panel 21, and the back waist section 30 is formed by the back cover panel 32 and the outer cover top panel 21. The outermost (upper) end of the back cover panel 32 in the longitudinal direction is folded back towards the skin to form a folded portion 32r. The folded portion 32r covers the other end (outer end) of the outer cover top panel 21 in the longitudinal direction. Alternatively, the outermost (upper) end of the back cover panel 32 in the longitudinal direction may not be folded back.

[0108] The ventral outer back panel 22 and the dorsal outer back panel 32 can be formed from hot-air nonwoven fabric, spunbond nonwoven fabric, SMS nonwoven fabric (spunbond / meltblown / spunbond nonwoven fabric), etc.

[0109] The ventral waist section 20 and the dorsal waist section 30 each have waist elastic members 23 and 33 (e.g., elastic bands) capable of stretching and contracting in the left-right direction. Multiple waist elastic members 23 are arranged with vertical spacing between the outer top panel 21 and the ventral outer back panel 22, and multiple waist elastic members 33 are arranged with vertical spacing between the outer top panel 21 and the dorsal outer back panel 32. Figure 3 and Figure 4 Additionally, in the back waist section 30, the rear leg elastic member 34 is provided between the outer top plate 21 and the back outer back plate 32. As an example, the waist elastic members 23 and 33, and the rear leg elastic member 34 can also be elastic members such as multiple elastic bands or elastic strips with elasticity. The waist elastic members 23 and 33, and the rear leg elastic member 34 are joined and fixed in their extended state by an adhesive such as a hot-melt adhesive. Furthermore, the adhesive used to join and fix the waist elastic member 23 is used to join and fix the outer top plate 21 and the ventral outer back plate 22, and the adhesive used to join and fix the waist elastic member 33 is used to join and fix the outer top plate 21 and the back outer back plate 32.

[0110] The basic structure of diaper 1 has been described above, but the structure of diaper 1 described above is an example and is not limited thereto. For example, in the diaper 1 of this embodiment, the structure is as follows: it has an outer body 18, which has three parts: a ventral waist portion 20, a dorsal waist portion 30, and a crotch portion 35 that connects the ventral waist portion 20 and the dorsal waist portion 30. However, it is not limited thereto. For example, it can be a diaper with a structure in which the ventral waist portion 20 and the dorsal waist portion 30 are composed of different components and the non-skin side of the absorbent body 10 is exposed at the crotch portion (so-called a three-piece diaper), or it can be a diaper with an outer body component composed of a single component that runs continuously from the ventral waist portion 20 to the dorsal waist portion 30 (so-called a two-piece diaper).

[0111] <<Packaged Diapers 1>>

[0112] like Figure 5 As shown, the packaging body 100, which stores multiple diapers 1, stores the multiple diapers 1 in a folded state with the diapers 1 adjacent to each other in the thickness direction. Preferably, 10 or more diapers 1 are stored in the storage member 101 in an adjacent state, and more preferably, 15 or more diapers 1 are stored in the storage member 101 in an adjacent state. Figure 5 This is a diagram illustrating the three diapers 1A, 1B, and 1C inside package 100. For example, in... Figure 5 Of the diapers 1A, 1B, and 1C shown that are adjacent to each other in the thickness direction, a central diaper 1A is arranged, along with diapers 1B and 1C on either side (in the thickness direction) of the central diaper 1A. Furthermore, the three adjacent diapers 1 within the packaging body 100 can be any three diapers 1. Diapers 1A, 1B, and 1C are each formed with the same structure, but their thickness may vary slightly depending on their position within the packaging body 100 in the stored state.

[0113] The folded diaper 1 is formed by folding a pair of vertical folds FL1 along the vertical direction and a pair of horizontal folds FL2 along the horizontal direction. As with diaper 1, it is preferable to fold the diaper 1 back in the forward and backward direction at the horizontal folds FL2, and fold the pair of waist parts 20, 30 back in the forward and backward direction at the vertical folds FL1.

[0114] Figure 6 This is a diagram illustrating how to fold diaper 1. Figure 6 A is a top view of diaper 1 taken from the back. First, as... Figure 6 As shown in Figure A, at a pair of upper and lower folds FL1, FL1, the two ends of the diaper 1 are folded back towards the back in the front-to-back direction, and set as follows: Figure 6The state shown in B. A pair of vertically folded portions FL1, FL1 are respectively provided along the vertical direction at a location further outward than the absorbent core 11. Alternatively, at the vertically folded portions FL1, FL1, at least the side ends of a pair of waist portions 20, 30 may be folded, and in addition to the side ends of the pair of waist portions 20, 30, the side ends of the crotch portion 35 may also be folded. Next, as shown in Figure B. Figure 6 As shown in Figure B, at the left-right fold FL2 along the left-right direction, fold the diaper 1 towards the ventral side in the front-back direction, thus forming... Figure 7 The folding state shown is 1 (1A). Figure 7 This diagram shows the diaper 1A in its folded state as viewed from the waist section 20 and 30 side. In addition, at the left and right folds FL2, the pair of waist sections 20 and 30 can also be folded back, and the crotch section 35 (absorbent body 10) can also be folded back.

[0115] <<Regarding the Central Diapers 1A>>

[0116] The following describes the central diaper 1A (hereinafter also referred to as "diaper 1A"). Figure 7 As shown, the diaper 1A in the folded state has a pair of waist sections 20 and 30, one side of which is folded back at the upper and lower fold section FL1 in the left and right direction, and the other side of which is folded back at the upper and lower fold section FL1 in the left and right direction, and has a non-folded back section N that is not folded back at the upper and lower fold sections FL1.

[0117] Figure 8 This indicates that diaper 1A has been removed from packaging 100 and 30 seconds have passed since then. Figure 7 The cross-section at the center line sc. Figure 8 The center line sc is the center of the side joint SS in the vertical direction, and is "a straight line passing through the center of the side joint SS in the vertical direction along the left and right direction". For convenience, in Figure 8 In the diagram, the fold-back section Ha on one side and the fold-back section Hb on the other side are represented by diagonal lines sloping downwards to the left, while the non-fold-back section N is represented by diagonal lines sloping downwards to the right.

[0118] Regarding diaper 1A, after removing diaper 1A from packaging 100 and unfolding the left and right folds FL2 after 30 seconds, in the aforementioned state, the average thickness T35 of the center CC in the left-right direction of the crotch portion 35 is less than the average value of the sum of the thickness Tha of the one-sided folded portion Ha and the thickness Tn of the non-folded portion N along the straight line in the left-right direction passing through the center sc in the vertical direction of the side joint SS (T35 < Tha + Tn). Furthermore, the average thickness T35 at the center CC in the left-right direction of the crotch portion 35 is 8 mm or less. In fact, the thicknesses of each diaper 1A after being removed from packaging 100 and unfolded at the left and right folds FL2 after 30 seconds are measured, but for convenience, [the following is omitted]. Figure 8 The description is based on the state where the diaper is not unfolded at the left and right folds FL2. The center CC in the left and right direction of the crotch 35 is the center CC in the left and right direction of the diaper 1A.

[0119] Each thickness can be measured using known methods. For example, it can be measured using a PEACOCK precision measuring device (such as the dial thickness gauge from Ozaki Seisakusho, or the spring-loaded type from the large JB model) or an equivalent device.

[0120] In this embodiment, the measurement was performed using the aforementioned equipment. Specifically, a probe with a diameter of 50 mm was used, and a measuring pressure of approximately 2 N was applied. The thickness at each location was measured three times, and the average value was calculated and designated as the "average thickness." The same method can be used for the thickness measurement described later.

[0121] In this embodiment, the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 of the diaper 1A is 7.1 mm, and the average value of the sum of the thickness Tha of the folded-back portion Ha and the thickness Tn of the non-folded-back portion N (T20) is 14.7 mm.

[0122] Furthermore, it is also possible to overlap the folded-back portion Ha on one side and the non-folded-back portion N (e.g. Figure 8 The thickness of the folded-back portion Ha and the thickness of the non-folded-back portion N can be measured in one measurement (total value). Alternatively, the thickness of the folded-back portion Ha and the thickness of the non-folded-back portion N can be measured separately and the measured values ​​of the thickness of the folded-back portion Ha and the non-folded-back portion N can be added together.

[0123] When removing diaper 1A from packaging 100, users typically apply pressure to remove diaper 1A in the thickness direction. Therefore, regarding diaper 1A removed from packaging 100, the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is 8 mm or less, and is less than the average value T20 of the sum of the thickness Tha of the side folded portion Ha and the thickness Tn of the non-folded portion N along the straight line in the left-right direction passing through the central sc in the up-down direction of the side joint SS. Thus, compared to the case where the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is greater than 8 mm, or compared to the case where the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is greater than the average value T20 of the sum of the thickness Tha of the side folded portion Ha and the thickness Tn of the non-folded portion N along the straight line of the central sc, when grasping and removing diaper 1A from packaging 100, it is easier for users of diaper 1A to actually feel that the thickness of the crotch portion 35 of diaper 1A is thinner. In particular, since the diaper 1 is stored in a folded state, when the diaper 1A is taken out of the packaging body 100 and one hand (e.g., the right hand) grasps the center sc of the waist part 20, 30 in the vertical direction passing through the side joint SS along the straight line in the horizontal direction or near it, and the other hand (e.g., the left hand) grasps the center of the crotch part 35 in the horizontal direction or near it and unfolds it at the left and right folds FL2, the user can actually feel that the thickness brought by grasping with one hand is different from the thickness brought by grasping with the other hand. Therefore, the user can easily feel that the thickness of the crotch part 35 is thinner.

[0124] Furthermore, for typical disposable diapers, the crotch portion with the absorbent core (absorbent body) is relatively thick, thus reducing the number of disposable diapers that can be stored in the storage member. In contrast, for diaper 1A, the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is less than 8 mm. Therefore, compared to cases where the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is greater than 8 mm, the overall thickness of diaper 1A can be reduced. Consequently, in the packaged state, it is easier to compress diaper 1 in the thickness direction, increasing the number of diapers 1A (diaper 1) stored in the storage member 101. As described above, in the packaging body 100, it is preferable that 10 or more diapers 1 are stored adjacent to each other in the thickness direction within the storage member 101, and more preferably, 15 or more diapers 1 are stored adjacent to each other in the thickness direction within the storage member 101. In this way, by forming a packaging body 100 that can hold more diapers 1 within the storage member 101, logistics costs, display space, and storage space can be reduced without decreasing the number of diapers 1 within the packaging body 100. Furthermore, by setting the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 of the diaper 1A to 8mm or less, the overall thickness of the diaper 1A can be reduced compared to the case where the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is greater than 8mm. Therefore, the necessity of excessively compressing the diaper 1A (diaper 1) within the storage member 101 is reduced, and the diaper 1A can be easily removed from the packaging body 100 compared to the case of excessively compressing the diaper 1.

[0125] Furthermore, regarding diaper 1A, various methods can be employed to ensure that the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is 8 mm or less, and is less than the average value of the sum T20 of the thickness Tha of the side fold-back portion Ha and the thickness Tn of the non-fold-back portion N along a straight line in the left-right direction passing through the central sc in the up-down direction of the side joint portion SS. For example, the thickness of the absorbent core 11 can be adjusted according to the shape of the absorbent core 11, the unit area weight of the pulp fibers constituting the absorbent core 11, and the unit area weight of the superabsorbent polymer (SAP), and the thickness of the pair of waist portions 20 and 30 can be adjusted according to the type of fiber, basis weight, adhesive, etc., of the sheet members 21, 22, 32, etc. constituting the pair of waist portions 20 and 30. Furthermore, the thickness of the crotch portion 35 and the pair of waist portions 20 and 30 can be adjusted by changing the folding method when stored in the packaging body 100 or by compressing it with a predetermined pressure in the stored state of the packaging body 100.

[0126] Furthermore, regarding diaper 1A, it is preferable that, when diaper 1A is removed from packaging 100 and the left and right folds FL2 are unfolded after 30 seconds, the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is less than the average thickness Tn of the non-folded portion N along the straight line in the left-right direction passing through the central sc in the up-down direction of the side joint SS (T35 < Tn). Therefore, compared to the case where the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 is greater than the average thickness Tn of the non-folded portion N along the straight line of the central sc, when diaper 1A is grasped and removed from packaging 100, the user of diaper 1A is more likely to perceive that the crotch portion 35 of diaper 1A is thinner.

[0127] Additionally, in the ventral waist portion 20, a pair of sheet portions (outer top sheet 21 and ventral outer back sheet 22) are bonded together with adhesive. Preferably, the ventral waist portion 20 has a non-adhesive area without adhesive along a predetermined length from the top end in the vertical direction. Specifically, as... Figure 9 As shown, in diaper 1A, there is a folded portion 22r at the upper end of the abdominal waist section 20. Figure 9 This diagram illustrates the adhesive and non-adhesive areas of diaper 1A. Figure 9 The non-adhesive regions n22, n32 and adhesive regions a22, a32 of the diaper 1A in its unfolded and extended state are shown. The elastic waist members 23, 33, etc., are omitted from the diagram. Figure 9 In the diagram, the adhesive areas a22 and a32 are indicated by diagonal lines sloping downwards to the right. The folded-back portion 22r has an adhesive area a22, in which the outer top piece 21, folded back from the non-skin side towards the skin side, is adhesively bonded to the skin side of the abdominal outer back piece 22. In this folded-back portion 22r, a non-adhesive area n22, without adhesive, is provided along a predetermined length in the vertical direction from the top of the abdominal waist portion 20.

[0128] Generally, the portion between a pair of sheet sections where no adhesive is applied (non-adhesive area) tends to be thicker and softer than the portion where adhesive is applied (adhesive area). In other words, the portion of the ventral waist section 20 with the non-adhesive area n22 can be made thicker and softer than the portion with the adhesive area a22. This makes it easier to increase the difference between the thickness T20 of the folded-back portion Ha and the thickness Tn of the non-folded-back portion N relative to the thickness T35 of the crotch section 35. Furthermore, as... Figure 1As shown, when the diaper 1A is stored with the upper part of its abdominal waist section 20 located above the packaging body 100, the part that the user touches first is the upper part of the abdominal waist section 20, making it easy for the user to feel the softness and thickness of this part. This, in turn, gives the user the feeling that the crotch area 35 of the diaper 1A is relatively thin.

[0129] Similarly, in the back side waist portion 30, a pair of sheet portions (outer top sheet 21 and back side outer back sheet 32) are bonded together with adhesive. Preferably, the back side waist portion 30 has a non-adhesive area without adhesive along a predetermined length from the top end in the vertical direction. Specifically, as Figure 9 As shown, in diaper 1A, a folded-back portion 32r is provided at the upper end of the back waist section 30. The folded-back portion 32r has an adhesive area a32 in which the outer top piece 21, which is folded back from the non-skin side to the skin side, is adhesively bonded to the skin side of the back outer back piece 32. In the folded-back portion 32r, a non-adhesive area n32 without adhesive is provided at a predetermined length in the vertical direction from the upper end of the back waist section 30.

[0130] This allows the portion of the back waist section 30 with the non-adhesive region n32 to be thicker and more flexible than the portion with the adhesive region a32. Consequently, the difference T20 between the sum of the thickness Tha of the folded-back portion Ha and the thickness Tn of the non-folded-back portion N, which is easily enlarged, and the thickness T35 of the crotch section 35, is reduced. Furthermore, as... Figure 1 As shown, when the diaper 1A is stored with the upper part of the back waist section 30 located above the packaging body 100, the part that the user touches first is the upper part of the back waist section 30, making it easy for the user to feel the softness and thickness of the upper part of the back waist section 30. This makes it easier for the user to perceive that the crotch area 35 of the diaper 1A is relatively thin.

[0131] In diaper 1A, a non-adhesive area n22 is provided on the abdominal waist portion 20, and a non-adhesive area n32 is provided on the back waist portion 30, but it is not limited to this. It is also possible that either the abdominal waist portion 20 or the back waist portion 30 has a non-adhesive area. However, by having non-adhesive areas n22 and n32 on both the abdominal waist portion 20 and the back waist portion 30, it is easier for users to perceive that the crotch area 35 of diaper 1A is thinner.

[0132] Additionally, preferably, for the folded state ( Figure 7When the diaper 1A (etc.) is unfolded with the folded-back portion Ha on one side and the folded-back portion Hb on the other side folded back at the upper and lower folds FL1 and FL1 respectively unfolded, when viewed in the front and back direction, the upper and lower folds FL1 have a portion that overlaps with the non-adhesive areas n22 and n32.

[0133] exist Figure 9 The diagram shows the upper and lower folded portions FL1 and FL2 in their unfolded and extended states. The positions of the upper and lower folded portions FL1 and FL2 differ from their folded state due to the contraction of the waist elastic members 23 and 33, but the relative positional relationship between the non-adhesive regions n22 and n32 and the upper and lower folded portions FL1 and FL2 remains the same in both the unfolded and extended and folded states. Therefore, the method of using... Figure 9 Let me explain.

[0134] like Figure 9 As shown, for diaper 1A, when viewed along the front-to-back direction (thickness direction), the upper and lower folds FL1 overlap with the non-adhesive area n22 of the abdominal waist portion 20. Furthermore, when viewed along the front-to-back direction (thickness direction), the upper and lower folds FL1 overlap with the non-adhesive area m32 of the back waist portion 30. This easily increases the difference between the thickness T20 of the sum of the thickness Tha of the lateral fold Ha and the thickness Tn of the non-fold N and the thickness T35 of the crotch portion 35. Additionally, as... Figure 1 As shown, when the upper ends of the waist sections 20 and 30 of the diaper 1A are located above the packaging body 100, the part that the user first touches is the upper end of the waist sections 20 and 30, making it easy for the user to feel the softness and thickness of the upper ends of the waist sections 20 and 30. This makes it easier for the user to perceive that the crotch area 35 of the diaper 1A is relatively thin.

[0135] In addition, such as Figure 9 As shown, the absorbent body 10 of the diaper 1 is bonded to the outer top piece 21 in the bonding area a10 using an adhesive such as a hot melt adhesive. On the other hand, in the pair of waist sections 20 and 30, the outer top piece 21 and the outer back pieces 22 and 32 are joined mainly using adhesives attached to the waist elastic members 23 and 33. In this case, it is preferable to set the total area of ​​the bonding area a where the absorbent body 10 and the outer top piece 21 are joined to be larger than the total area of ​​the bonding area where the outer top piece 21 and the outer back pieces 22 and 32 are joined in the pair of waist sections 20 and 30. This makes it easier to increase the difference between the thickness T20 of the folded-back portion Ha and the thickness Tn of the non-folded-back portion N and the thickness T35 of the crotch portion 35, making it easier for users to feel that the crotch portion 35 of the diaper 1A is thinner.

[0136] Preferably, at least one of the waist sections 20 and 30 has an upper region sa that is above the center sc in the vertical direction of the side joint SS, and a lower region sb that is below the center sc in the vertical direction of the side joint SS. The force per unit length in the vertical direction for extending the upper region sa by a predetermined length in the horizontal direction is greater than the force per unit length in the vertical direction for extending the lower region sb by a predetermined length in the horizontal direction. The greater the force per unit length in the vertical direction for extending the predetermined length in the horizontal direction, the easier it is to contract. Therefore, the upper region sa is easier to contract than the lower region sb, thereby making it easier for the thickness of the upper end sa of the waist sections 20 and 30 to become thicker. As a result, it is easier to increase the difference between the sum T20 of the thickness Tha of the folded-back portion Ha and the thickness Tn of the non-folded-back portion N and the thickness T35 of the crotch portion 35, making it easier for users to feel that the thickness of the crotch portion 35 is thinner. In addition, as Figure 1 As shown, when the diaper 1A is stored with the upper ends of the waist sections 20 and 30 located above the packaging body 100, the part that the user touches first is the upper end of the waist sections 20 and 30, and the user can easily feel the softness and thickness of the upper end of the waist sections 20 and 30.

[0137] In a pair of waist sections 20 and 30, the force per unit length in the vertical direction for extending the upper region sa by a unit length in the lateral direction and the force per unit length in the vertical direction for extending the lower region sb by a unit length in the lateral direction can be compared using a known method. For example, all or part of the upper region sa and the lower region sb are cut from the ventral waist section 20 (dorsal waist section 30) to obtain samples. Then, the average vertical length of each sample is calculated. Furthermore, the two ends of the sample are clamped in the chucks of a tensile testing machine. The load obtained when the sample is elongated by separating the chucks by a unit length is measured. Then, the values ​​obtained by dividing the load of each sample by the average vertical length of each sample are compared.

[0138] Preferably, at least one of the pair of waist sections 20, 30 has a plurality of elastic bands 23, 33 that are fixed between the pair of sheet sections (outer top sheet 21 and ventral outer back sheet 22, outer top sheet 21 and back outer back sheet 32) and extend and retract in the left-right direction. Preferably, regarding these elastic bands 23, 33, the interval Pa between adjacent elastic bands 23, 33 in the upper region sa in the vertical direction is shorter than the interval Pb between adjacent elastic bands 23, 33 in the vertical direction in the lower region sb. Furthermore, if the intervals between adjacent elastic bands 23, 33 in the vertical direction in the upper region sa or the lower region sb are unequal, the length of the shortest interval between adjacent elastic bands 23, 33 in the vertical direction is used for comparison.

[0139] The shorter the interval between adjacent elastic bands 23 and 33 in the vertical direction, the easier it is to contract. Therefore, by making the upper region sa more easily contractible than the lower region sb, the thickness of the upper end sa of the waist section 20 and 30 can be easily increased. This makes it easier to increase the difference between the sum T20 of the thickness Tha of the folded-back section Ha and the thickness Tn of the non-folded-back section N and the thickness T35 of the crotch section 35, easily giving the user the actual feeling that the crotch section 35 is thinner. Furthermore, as... Figure 1 As shown, when the diaper 1A is stored with the upper ends of the waist sections 20 and 30 located above the packaging body 100, the part that the user touches first is the upper end of the waist sections 20 and 30, and the user can easily feel the softness and thickness of the upper end of the waist sections 20 and 30.

[0140] Preferably, in diaper 1A, in the folded state, the folded portion Ha on one side and the folded portion Hb on the other side are separated in the left-right direction. That is, as... Figure 7 As shown, it can also be in the following state: when viewing the folded diaper 1A along the thickness direction, a non-folded portion N is provided between the folded portion Ha on one side and the folded portion Hb on the other side in the left-right direction. Even when the folded portion Ha on one side and the folded portion Hb on the other side are separated in the left-right direction, the diaper 1A easily gives the user the actual feeling that the crotch area 35 is thinner.

[0141] Preferably, when the folded-back portion Ha on one side and the folded-back portion Hb on the other side are separated in the left-right direction in the folded state, the length Ha of the folded-back portion Ha in the left-right direction is longer than the distance N1 from the side end of the folded-back portion Ha on one side to the side end of the folded-back portion Hb on the other side in the left-right direction (Ha > N1).

[0142] Alternatively, for diaper 1A, in the folded state, one side fold-back portion Ha and the other side fold-back portion Hb may overlap in the left-right direction (not shown). Even when one side fold-back portion Ha and the other side fold-back portion Hb overlap in the left-right direction in the folded state, it is easy for users to perceive that the crotch area 35 is thinner.

[0143] Furthermore, preferably, the pair of waist sections 20 and 30 are respectively the ventral waist section 20 and the dorsal waist section 30, which are equipped with waist elastic members (elastic members) 23 and 33 that can stretch in the left and right directions. The color of the waist elastic member 23 of the ventral waist section 20 is different from the color of the waist elastic member 33 of the dorsal waist section 30. In diaper 1A, the waist elastic member 23 of the ventral waist section 20 is a white elastic band, and the waist elastic member 33 of the dorsal waist section 30 is a blue elastic band. This makes it easy for users to identify the front and back directions of diaper 1.

[0144] Preferably, such as Figure 7 As shown, in the folded state of diaper 1A after being removed from packaging 100 for 30 seconds, the vertical length Lea from the outer end ec of the left and right folding portions FL2 to the upper end ea of ​​the waist portions 20 and 30 is longer than the vertical length Leb from the outer end ec of the left and right folding portions FL2 to the lower end eb of the crotch portion 35 (Lea > Leb). In other words, for diaper 1A, the upper ends ea of ​​the waist portions 20 and 30 are positioned beyond the lower end eb of the crotch portion 35 and away from the left and right folding portions FL2 in the folded state. Therefore, compared to the case where the vertical length Lea from the outer end ec to the upper end ea is shorter than the vertical length Leb from the outer end ec to the lower end eb, the crotch portion 35 is less likely to appear bulging due to its thickness, making it easier for users to perceive that the crotch portion 35 is thinner.

[0145] As described above, the diaper 1A has an absorbent body 10 with an absorbent core 11 in the crotch portion 35. Regarding the diaper 1A in its folded state after being removed from the packaging 100 and after 30 seconds, it is preferable that, when viewed from the front-to-back direction (thickness direction), the absolute value of the difference between the average thickness T35 of the crotch portion 35 where the absorbent body 10 overlaps with the portion where the absorbent body 10 does not overlap with the portion where the crotch portion 35 does not overlap with the portion where the absorbent body 10 overlaps with the portion where the crotch portion 35 does not overlap with the portion where the crotch portion 35 overlaps with the portion where the absorbent body 10 overlaps with the portion where the crotch portion 35 overlaps with the portion where the crotch portion 35 overlaps with the portion where the crotch portion 35 overlaps with the portion where the crotch portion 35 overlaps with the portion where the crotch portion 35 overlaps with the portion where the crotch portion 35 overlaps with the portion where the crotch portion 30 ... Figure 7 and Figure 8As shown, for diaper 1, in the folded state, the absorbent body 10 overlaps with a pair of waist sections 20 and 30 throughout the entire area in the front-to-back direction (thickness direction). Therefore, the average thickness of the crotch portion 35 of the part of the absorbent body 10 that does not overlap with the pair of waist sections 20 and 30 is 0 (zero), and the absolute value of the average thickness T35 of the crotch portion 35 of the part of the absorbent body 10 that overlaps with the pair of waist sections 20 and 30 is greater than the thickness Tn of the non-folded portion N along the straight line in the left-right direction at the center sc in the up-down direction passing through the side joint SS (T35-0>Tn). Therefore, when observing the diaper 1A in its folded state after being removed from the packaging body 100 for 30 seconds, from the front-to-back direction, the absolute value of the difference between the average thickness T35 of the crotch portion 35 where the absorbent body 10 and the pair of waist portions 20, 30 overlap and the average thickness of the crotch portion 35 where the absorbent body 10 and the pair of waist portions 20, 30 do not overlap is less than the thickness Tn of the non-folded portion N along the straight line in the left-right direction at the center sc in the vertical direction passing through the side joint SS, it is easier for users to perceive that the crotch portion 35 is thinner.

[0146] <<Packaging Group 900>>

[0147] The packaging assembly 900 for shorts-type absorbent items comprises multiple packaging units 100 and 500 for shorts-type absorbent items. Figure 10 This is a diagram illustrating package 900. Figure 10 A is a perspective view of the packaging body of the first type of absorbent article (hereinafter also referred to as "the first packaging body") 100. Figure 10 B is a perspective view of the packaging of the second type of absorbent article (hereinafter also referred to as the "second packaging").

[0148] Figure 10 The first packaging body 100 shown in Figure A has a plurality of first shorts-type disposable diapers 1 (hereinafter also referred to as "first diapers 1") and a first storage member 101. The first storage member 101 stores three or more first diapers 1 that are adjacent to each other and displays a predetermined brand name 103. Furthermore, the first packaging body 100, the first diapers 1, and the first storage member 101 have substantially the same structure as the packaging body 100, diapers 1, and storage member 101 described above, so detailed descriptions are omitted.

[0149] Figure 10 The second package 500 shown in B has multiple second shorts-type disposable diapers 5 (hereinafter also referred to as "second diapers 5") and a second storage member 501. The second storage member 501 stores three or more second diapers 5 adjacent to each other and displays a predetermined brand name 503.

[0150] "Brand name" refers to the name used by a manufacturer or seller of various absorbent articles to distinguish a particular group of absorbent articles from other groups of absorbent articles. In the packaging group 900 of this embodiment, such as... Figure 10 As shown, each package 100, 500 (storage components 101, 501) is labeled with the brand name "ABC pants" 103, 503 for diapers 1 and 5 respectively. This allows the manufacturer or seller of diapers 1 and 5 to identify them as belonging to a specific package group 900. Furthermore, the first diaper 1 of the first package 100 and the second diaper 5 of the second package 500 are related products.

[0151] Similar to the first diaper 1, the second diaper 5 is a disposable shorts-type diaper for adults. However, the first diaper 1 (first packaging 100) is a single-use product, while the second diaper 5 (second packaging 500) is a product capable of absorbing excrement from multiple excretions. The first packaging 100 (first storage member 101) and the second packaging 500 (second storage member 501) are marked with the same brand names 103 and 503, but in the first storage member 101 (first packaging 100), as... Figure 10 As shown in Figure A, a label 105 indicating that the product is for single excretion is provided in the second storage component 501 (second packaging body 500), as follows: Figure 10 As shown in Figure B, there is no marking indicating that the product is for single-use. However, the second storage member 501 (second packaging 500) has a marking 505 indicating that the product is for multiple-use. Therefore, when comparing packaging groups 900 with the same brand name (103, 503), it is easy for users to identify that the first packaging 100 is for single-use. On the other hand, it is easy for users to identify that the second packaging 500 is for multiple-use.

[0152] Furthermore, in this embodiment, the first diaper 1 of the first packaging body 100 is designed for single-use, and the second diaper 5 of the second packaging body 500 is designed for multiple-use, but is not limited thereto. The first diaper 1 of the first packaging body 100 and the second diaper 5 of the second packaging body 500 may also be designed for multiple-use. However, when the first diaper 1 and the second diaper 5 are both designed for multiple-use, it is preferable that the number of times the first diaper 1 is intended to be used is less than the number of times the second diaper 5 is intended to be used.

[0153] Figure 11 This is a rough 3D diagram of diaper #2. Figure 12 This is a rough top view of the second diaper 5, viewed from the wearer's skin side, showing it in its unfolded and elongated state. Figure 13 yes Figure 12 A rough cross-sectional view at point AA.

[0154] For the parts of the second package 500 and the second diaper 5 that share the same structure as the first package and the first diaper 1, the reference numerals and other designations are made the same, and detailed descriptions of their basic structures are omitted. Figures 11-13 As shown, the basic structure of the second diaper 5 is the same as that of the first diaper 1, but the structure of the absorbent core 11 of the second diaper 5 and the first diaper 1 is different.

[0155] The absorbent core 11 of the second diaper 5 is thicker than the absorbent core 11 of the first diaper 1 (see reference). Figure 4 and Figure 13 The area weight of the pulp fiber in the absorbent core 11 of the second diaper 5 is approximately twice that of the pulp fiber in the first diaper 1, and the area weight of the superabsorbent polymer (SAP) in the absorbent core 11 of the second diaper 5 is approximately three times that of the superabsorbent polymer (SAP) in the absorbent core 11 of the first diaper 1. Therefore, the second diaper 5 can absorb excrement even after multiple bowel movements.

[0156] Similar to the first packaging body 100, the second packaging body 500 also houses multiple second diapers 5 in a folded state. Among the second diapers 5 in the folded state, a central second diaper 5A is positioned among the second diapers 5A, 5B, and 5C adjacent to each other along the thickness direction, and second diapers 5B and 5C are positioned on either side of the central second diaper 5A (on either side of the thickness direction). Furthermore, any three adjacent second diapers 5 within the packaging body 500 can be arranged. The second diapers 5A, 5B, and 5C are each formed with the same structure, but their thickness may vary slightly depending on their position within the packaging body 500 in the folded state.

[0157] Similar to the first diaper 1, the second diaper 5 in its folded state is formed by folding at a pair of vertical folds FL1 along the vertical direction and at a pair of horizontal folds FL2 along the horizontal direction. Preferably, similar to the first diaper 1, the second diaper 5 is folded back at the horizontal folds FL2 to one side (back side) in the forward and backward direction, and the pair of waist sections 20, 30 are folded back at the vertical folds FL1 to the other side (abdominal side) in the forward and backward direction.

[0158] <<Regarding Central Diaper No. 1A and Central Diaper No. 2A>>

[0159] The following describes the central diaper 1A (hereinafter also referred to as "diaper 1A") and the central diaper 5A (hereinafter also referred to as "diaper 2A"). Figure 14As shown, the second diaper 5A in the folded state has a pair of waist sections 20 and 30, one side of which is folded back at the upper and lower fold section FL1 in the left and right direction, and the other side of which is folded back at the upper and lower fold section FL1 in the left and right direction, and has a non-folded back section N that is not folded back at the upper and lower fold sections FL1. Figure 14 This is a diagram of the second diaper 5A in its folded state, viewed from the waist 20 and 30 sides.

[0160] Figure 15 This indicates that the second diaper 5A was removed from the packaging 500 and 30 seconds have passed since then. Figure 14 The cross-section at the center line sc. Figure 14 The center line sc is the center of the side joint SS in the vertical direction, and is "a straight line passing through the center of the side joint SS in the vertical direction along the left and right direction". For convenience, in Figure 15 In the diagram, the fold-back section Ha on one side and the fold-back section Hb on the other side are represented by diagonal lines sloping downwards to the left, while the non-fold-back section N is represented by diagonal lines sloping downwards to the right.

[0161] Regarding package group 900, such as Figures 1 to 8 As shown, when the first diaper 1A is removed from the first packaging body 100 and the left and right folds FL2 are unfolded after 30 seconds, the average thickness T35 of the center CC in the left and right direction of the crotch portion 35 is less than the average value of the sum of the thickness Tha of the one-sided folded portion Ha and the thickness Tn of the non-folded portion N (T20) along the straight line in the left and right direction through the center sc in the up and down direction of the side joint SS (T35 < Tha + Tn). In addition, the average thickness T35 at the center CC in the left and right direction of the crotch portion 35 is 8 mm or less.

[0162] On the other hand, with the second diaper 5A removed from the second packaging unit 500 and the left and right folds FL2 unfolded after 30 seconds, the average thickness T35 at the center CC in the left-right direction of the crotch portion 35 is greater than 8 mm. Furthermore, in practice, the thicknesses of each diaper 5A with the left and right folds FL2 unfolded after 30 seconds from being removed from the second packaging unit 500 were measured, but for convenience, [the following is omitted]. Figure 15 The description is based on the state where the diaper is not unfolded at the left and right folds FL2. The center CC in the left and right direction of the crotch 35 is the center CC in the left and right direction of the second diaper 5A.

[0163] As described above, the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 of the first diaper 1A is 7.1 mm, and the average value of the sum of the thickness Tha of the folded-back portion Ha and the thickness Tn of the non-folded-back portion N (T20) is 14.7 mm. Furthermore, the average thickness T35 of the central CC in the left-right direction of the crotch portion 35 of the second diaper 5A is 12.7 mm.

[0164] When comparing the first package 100 and the second package 500 of the packaging group 900 which have the same brand names 103 and 503, it is easy for users to identify that the crotch portion 35 of the first diaper 1 in the first package 100 is thinner than that of the second diaper 5 in the second package. Furthermore, even when the first diaper 1A and the second diaper 5A are removed from the first storage member 101 and the second storage member 501 respectively, users can easily distinguish between the first diaper 1A and the second diaper 5A based on the thinness of the crotch portion 35. In particular, since the first diaper 1A and the second diaper 5A are stored in a folded state, when diapers 1A and 5A are taken out from the packaging bodies 100 and 500, and one hand (e.g., the right hand) grasps the center sc of the waist part 20 and 30 in the vertical direction passing through the side joint SS along the straight line in the horizontal direction or near it, and the other hand (e.g., the left hand) grasps the center of the crotch part 35 in the horizontal direction or near it, and unfolds it at the left and right folding parts FL2, one can actually feel that the tactile sensation brought by grasping with one hand is different from that brought by grasping with the other hand in the first diaper 1A and the second diaper 5A. Therefore, users can actually feel that the crotch part 35 of the first diaper 1A is thinner than the crotch part 35 of the second diaper 5A, making it easy to distinguish the two diapers 1A and 5A, which are related products and similar in appearance.

[0165] Furthermore, preferably, when the second diaper 5A is removed from the second packaging body 500 and the left and right folds FL2 are unfolded after 30 seconds, the average thickness T35 of the center CC in the left and right direction of the crotch portion 35 is greater than the average value of the sum of the thickness Tha of the one-sided folded portion Ha and the thickness Tn of the non-folded portion N (T20) along the straight line in the left and right direction through the center sc in the up and down direction of the side joint SS (T35 > Tha + Tn). Therefore, when comparing the first packaging body 100 and the second packaging body 500 of the packaging body group 900 having the same brand names 103 and 503, it is easy for users to identify that the crotch portion 35 is thinner for the first diaper 1 of the first packaging body 100 compared to the second diaper 5 of the second packaging body. Furthermore, even when the first diaper 1A and the second diaper 5A are removed from the first storage member 101 and the second storage member 501 respectively, users can easily distinguish between the first diaper 1A and the second diaper 5A based on the thinness of the crotch area 35.

[0166] Furthermore, preferably, for the first diaper 1A in its folded state 30 seconds after being removed from the first package 100, such as... Figure 7 The difference (Lea-Leb) between the vertical length Lea from the outer end ec of the left and right folding sections FL2 to the upper end ea of ​​the waist section 20, 30 and the vertical length Leb from the outer end ec of the left and right folding sections FL2 to the lower end eb of the crotch section 35 is different from the folded state of the second diaper 5A after it has been removed from the second packaging body 500 and 30 seconds have passed. Figure 14 The difference between Lea (Lea-Leb) and Leb (Lea-Leb) is the vertical length Lea from the outer end ec of the left and right folding section FL2 in the vertical direction to the upper end ea of ​​the waist section 20, 30.

[0167] Furthermore, more preferably, in the folded state of the first diaper 1A after 30 seconds of being removed from the first packaging 100, such as... Figure 7 As shown, the vertical length Lea from the outer end ec of the left and right folding section FL2 to the upper end ea of ​​the waist section 20, 30 is longer than the vertical length Leb from the outer end ec of the left and right folding section FL2 to the lower end eb of the crotch section 35 (Lea > Leb). In the folded state of the second diaper 5A after 30 seconds of being removed from the second packaging body 500, as... Figure 14As shown, the length Leb in the vertical direction from the outer end ec of the left and right folding part FL2 to the lower end eb of the crotch part 35 is longer than the length Lea in the vertical direction from the outer end ec of the left and right folding part FL2 to the upper end ea of ​​the waist part 20, 30 (Lea < Leb).

[0168] By using diapers 1A and 5A in this way, when comparing the first package 100 and the second package 500 of the packaging assembly 900 which have the same brand names 103 and 503, it is easy for users to identify that the crotch portion 35 of the first diaper 1 in the first package 100 is thinner than that of the second diaper 5 in the second package. Furthermore, even when the first diaper 1A and the second diaper 5A are removed from the first storage member 101 and the second storage member 501 respectively, users can easily distinguish between the first diaper 1A and the second diaper 5A based on the thinness of the crotch portion 35.

[0169] Figure 16 and Figure 17 This is a schematic diagram illustrating the action of unfolding the left and right folds FL2 of the first diaper 1A and the second diaper 5A until the angle formed by the side joint SS and the crotch 35 becomes 100 degrees.

[0170] After removing the first diaper 1A from the first package 100 and placing the first diaper 1A with the pair of waist sections 20 and 30 folded back at the upper and lower folds FL1 facing upwards for 100 seconds, unfold one folded section Ha and the other folded section Hb, as follows. Figure 16 As shown in Figure A, the left and right folds FL2 are unfolded until the angle between the side joint SS and the crotch portion 35 reaches 100 degrees. At this point, to ensure the left and right folds FL2 are unfolded until the angle between the side joint SS and the crotch portion 35 reaches 100 degrees, the pair of waist sections 20 and 30 can be unfolded by applying force generated by a person's hand, or a predetermined machine or device can be used. The first diaper 1A is generally soft, therefore, by applying external force, it is possible to maintain the angle between the side joint SS and the crotch portion 35 at 100 degrees.

[0171] Regarding the first diaper 1A, where the angle between the side joint SS and the crotch 35 is 100 degrees, when the force applied to the first diaper 1A is released, as... Figure 16 As shown in B, the angle between the side joint SS and the crotch portion 35 becomes greater than 100 degrees. That is, the pair of waist parts 20 and 30 tilt to the side opposite to the crotch portion 35.

[0172] On the other hand, after removing the second diaper 5A from the second package 500 and placing the second diaper 5A with the pair of waist sections 20 and 30 folded back at the upper and lower folds FL1 facing upwards for 100 seconds, the folded-back section Ha on one side and the folded-back section Hb on the other side are unfolded, as follows: Figure 17 As shown in Figure A, the left and right folds FL2 are unfolded until the angle between the side joint SS and the crotch portion 35 reaches 100 degrees. At this point, to ensure the left and right folds FL2 are unfolded until the angle between the side joint SS and the crotch portion 35 reaches 100 degrees, the pair of waist sections 20 and 30 can be unfolded by applying force generated by a person's hand, or a predetermined machine or device can be used. The second diaper 5A is generally soft, therefore, by applying external force, it is possible to maintain the angle between the side joint SS and the crotch portion 35 at 100 degrees.

[0173] Regarding the second diaper 5A, where the angle between the side joint SS and the crotch 35 is 100 degrees, when the force applied to the second diaper 5A is released, as... Figure 17 As shown in B, the angle between the side joint SS and the lower crotch 35 becomes smaller than 100 degrees. That is, the pair of waist parts 20 and 30 tilt towards the lower crotch 35.

[0174] Based on this packaging assembly 900 having a first diaper 1A and a second diaper 5A, when comparing the first packaging assembly 100 and the second packaging assembly 500 of the packaging assembly 900 having the same brand names 103 and 503, it is easy for users to identify that the crotch portion 35 of the first diaper 1 in the first packaging assembly 100 is thinner than that of the second diaper 5 in the second packaging assembly. Furthermore, even when the first diaper 1A and the second diaper 5A are removed from the first storage member 101 and the second storage member 501 respectively, users can easily distinguish between the first diaper 1A and the second diaper 5A based on the thinness of the crotch portion 35.

[0175] The embodiments of this patent have been described above. However, the above embodiments are intended to facilitate the understanding of this patent and are not intended to limit the interpretation of this patent. Furthermore, it is self-evident that this patent can be modified and improved without departing from its spirit, and equivalents are included in this patent.
