[0005] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2022-12041 Summary of the Invention

[0006] Problems to be Solved by the Invention

[0007] In the decorated sheet of Patent Document 1, an identification layer is formed by pressing a foil. Therefore, the identification layer is concave with respect to the surroundings and smooth. Thus, when using the decorated sheet of Patent Document 1 to form a storage body for absorbent article packages, the user is likely to have an impression that the absorbent article is also a flat product like the identification layer, and there may be a concern about whether the absorbent article is three-dimensionally deformed and conforms to the body.

[0008] In addition, a plurality of absorbent article packages are arranged and displayed in a store, or a plurality of absorbent article packages are purchased by a user together and stored in a bathroom or the like. In the decorated sheet of Patent Document 1, since the foil is pressed using a pattern roll, the identification layer is likely to be formed uniformly. However, when the user visually recognizes a plurality of packages, it is easy to feel monotonous. Therefore, there is a possibility that not only the interestingness of using ordinary ink-based printing is reduced, but also the interestingness of using foil decoration is reduced.

[0009] The present invention has been completed in view of the above problems, and an object thereof is to give the user an impression that the absorbent article stored is a product that is easily three-dimensionally deformed and conforms, and to further improve the interestingness of the decoration in an aggregate of absorbent article packages using a thin decorative layer.

Detailed Description of the Invention

[0046] According to the description in this specification and the drawings, at least the following matters are clarified.

[0047] (Aspect 1) An aggregate of packages of absorbent articles, characterized in that the aggregate of packages of absorbent articles includes: a plurality of packages of absorbent articles; and a bundle that bundles the plurality of packages of absorbent articles. The package of absorbent article has a storage body and a plurality of individual packages stored in the storage body. The storage body has a decorative sheet with decoration applied thereto. The decorative sheet has: a sheet; an adhesive layer provided on the surface of the sheet; and a decorative layer provided on the adhesive layer and having a maximum thickness of 10 μm or less. The decorative layer is provided at a position visually recognizable by the user and protrudes from the surface of the sheet in the thickness direction of the sheet. The plurality of packages of absorbent articles include a first package of absorbent article and a second package of absorbent article. The first package of absorbent article has a first decorative layer existing area where the decorative layer exists in the storage body, and the second package of absorbent article has a corresponding area corresponding to the first decorative layer existing area in the storage body. The corresponding area has a second decorative layer existing area where the decorative layer exists and a non-existing area where the decorative layer does not exist.

[0048] According to Method 1, even for a decorative layer with a relatively thin maximum thickness, it can protrude in the thickness direction of the sheet by overlapping with the adhesive layer. It can give the user who sees the protruding and three-dimensional decorative layer the impression that the absorbent article also deforms three-dimensionally and fits closely. In addition, while the first absorbent article package and the second absorbent article package create a sense of unity, there are design differences based on the presence or absence of the non-existent area. Thus, the user can identify the packages containing the same absorbent article and appreciate the design differences, further enhancing the interestingness of the three-dimensional decoration.

[0049] (Method 2) Based on the aggregate of the absorbent article packages described in Method 1, for each of the plurality of individual packages of the second absorbent article package, find the first length obtained by subtracting the maximum length in the lateral direction of the internal absorbent article from the maximum length in the lateral direction along the opening end of the individual package. Set the difference between the maximum value and the minimum value of the first length as the first deviation amount. At this time, the diameter of the circumscribed circle circumscribing the non-existent area is smaller than the first deviation amount.

[0050] According to Method 2, the first deviation amount of the individual packages contained in the package is small enough that the user does not have a sense of disharmony. The length of the non-existent area is smaller than the first deviation amount, so that the user is less likely to have a sense of disharmony about the presence or absence of the non-existent area and can appreciate the small design differences of the absorbent article package.

[0051] (Method 3) Based on the aggregate of the absorbent article packages described in Method 1 or 2, the individual package has a lateral direction along the opening end and a longitudinal direction orthogonal to the lateral direction. For each of the plurality of individual packages of the second absorbent article package, find the second length, which is the length in the longitudinal direction from the opening end to the internal absorbent article at the central position in the lateral direction. Set the difference between the maximum value and the minimum value of the second length as the second deviation amount. At this time, the diameter of the circumscribed circle circumscribing the non-existent area is smaller than the second deviation amount.

[0052] According to Method 3, the second deviation amount of the individual packages contained in the package is small enough that the user does not have a sense of disharmony. The length of the non-existent area is smaller than the second deviation amount, so that the user is less likely to have a sense of disharmony about the presence or absence of the non-existent area and can appreciate the small design differences of the absorbent article package.

[0053] (Method 4)

[0054] Based on the aggregate of absorbent article packages described in Mode 1, the individual package has a packaging sheet. At both ends of the individual package along the transverse direction of the opening end, the folded packaging sheets are joined to each other by a plurality of welding portions, and the area ratio of the non - existent region is smaller than the minimum value of the area of the welding portions provided in a certain individual package of the second absorbent article package.

[0055] According to Mode 4, it is not easy for the user to have a sense of disharmony about the presence or absence of the non - existent region, and small differences in the design of the absorbent article package can be appreciated.

[0056] (Mode 5) Based on the aggregate of absorbent article packages described in Mode 1 or 4, for each of the plurality of individual packages of the second absorbent article package, a first length is obtained by subtracting the maximum length in the transverse direction of the internal absorbent article from the maximum length in the transverse direction of the individual package along the opening end. The difference between the maximum value and the minimum value of the first length is set as the first deviation amount. At this time, the diameter of the circumscribed circle circumscribing the non - existent region is equal to or greater than the first deviation amount.

[0057] According to Mode 5, it is easy for the user to identify the non - existent region, and the differences in the design of the absorbent article package can be appreciated. In addition, the design of the portions with different textures (such as the adhesive layer) visually recognizable between the decorative layers can also be appreciated.

[0058] (Mode 6) Based on the aggregate of absorbent article packages described in Mode 1 or 5, the individual package has a transverse direction along the opening end and a longitudinal direction orthogonal to the transverse direction. For each of the plurality of individual packages of the second absorbent article package, a second length is obtained, which is the length in the longitudinal direction from the opening end to the internal absorbent article at the central position in the transverse direction. The difference between the maximum value and the minimum value of the second length is set as the second deviation amount. At this time, the diameter of the circumscribed circle circumscribing the non - existent region is equal to or greater than the second deviation amount.

[0059] According to Mode 6, it is easy for the user to identify the non - existent region, and the differences in the design of the absorbent article package can be appreciated. In addition, the design of the portions with different textures (such as the adhesive layer) visually recognizable between the decorative layers can also be appreciated.

[0060] (Mode 7) Based on the aggregate of absorbent article packages described in Modes 1, 5, and 6, the individual package has a packaging sheet. At both ends of the individual package along the transverse direction of the opening end, the folded packaging sheets are joined to each other by a plurality of welding portions, and the area of the non - existent region is equal to or greater than the minimum value of the area of the welding portions provided in a certain individual package of the second absorbent article package.

[0061] According to Mode 7, it is easy for the user to identify the non - existent region, and the user can appreciate the design differences of the absorbent article packages. In addition, the user can also appreciate the design of the portions (such as the adhesive layer) with different textures visually recognizable between the decorative layers.

[0062] (Mode 8) Based on the aggregate of absorbent article packages described in Modes 2 - 4, the individual package has a packaging sheet. At both ends of the individual package in the transverse direction, the folded packaging sheets are joined to each other by a plurality of welding portions. In a certain individual package of the second absorbent article package, the maximum value and the minimum value of the intervals between the adjacent welding portions in the transverse direction are obtained, and the difference between the maximum value and the minimum value of the intervals is defined as the third deviation amount. At this time, the diameter of the circumscribed circle circumscribing the non - existent region is larger than the third deviation amount.

[0063] According to Mode 8, the third deviation amount of the welding portions whose surfaces are formed with concave - convex shaped patterns is so small that the user will not notice it. Therefore, by making the length of the non - existent region larger than the third deviation amount, the user can identify the non - existent region and can appreciate the small design differences of the absorbent article packages.

[0064] (Mode 9) Based on the aggregate of absorbent article packages described in any one of Modes 1 - 8, the storage body has a stacking direction in which the plurality of individual packages are stacked along their thickness direction. In the second absorbent article package, the non - existent region is located on the surface of the storage body orthogonal to the stacking direction. The individual package has an article - existent portion where the absorbent article exists and a non - article - existent portion where the absorbent article does not exist. The non - existent region overlaps with the article - existent portion of at least one of the plurality of individual packages in the stacking direction.

[0065] According to Mode 9, the article - existent portion has a thickness compared to the non - article - existent portion. At the portion where the article - existent portion is located in the storage body, the sheet is stretched. The non - existent region located at this portion extends outward and is easily recognizable by the user.

[0066] (Aspect 10) Based on the aggregate of absorbent article packages described in Aspect 9, the absorbent article has an absorbent core. The absorbent article folded is contained in the individual package, and has a maximum stacking portion with the largest number of stacked layers of the folded absorbent core. The non - existent region overlaps with the maximum stacking portions of all the individual packages in the stacking direction.

[0067] According to Aspect 10, the portion where the maximum stacking portion of the absorbent core overlaps causes the sheet to stretch to the greatest extent. The non - existent region located at this portion extends further outward and is easily recognizable by the user.

[0068] (Aspect 11) Based on the aggregate of absorbent article packages described in Aspect 9, the absorbent article has an absorbent core. The absorbent article folded is contained in the individual package, and has a minimum stacking portion with the smallest number of stacked layers of the folded absorbent core. The non - existent region overlaps with the minimum stacking portions of all the individual packages in the stacking direction.

[0069] According to Aspect 11, the portion where the minimum stacking portion of the absorbent core overlaps causes the sheet to stretch moderately. The non - existent region located at this portion is not likely to open due to the sheet bending convexly outward, and can maintain the unevenness of the surface formed by the non - existent region and the decorative layer.

[0070] (Aspect 12) Based on the aggregate of absorbent article packages described in any one of Aspects 1 - 8, the storage body has a stacking direction in which the plurality of individual packages are stacked along its thickness direction. In the second absorbent article package, a non - existent region is provided on the surface of the storage body orthogonal to the stacking direction. The individual package has an article - existent portion where the absorbent article exists and a non - article - existent portion where the absorbent article does not exist. The non - existent region overlaps with the non - article - existent portions of all the individual packages in the stacking direction.

[0071] According to Aspect 12, the non - existent region is located at the portion where the storage body is inclined from the portion overlapping with the article - existent portion to the portion overlapping with the non - article - existent portion. A user visually recognizing the storage body in the stacking direction can easily notice the depression of the non - existent region. Thus, the user can appreciate the difference in the impression of the three - dimensional decoration caused by the presence or absence of the non - existent region.

[0072] (Aspect 13) Based on the aggregate of absorbent article packages described in any one of Aspects 1 - 12, the decorative layer of the second absorbent article package has: a first decorative layer portion; and a second decorative layer portion, which has a larger area of the decorative layer per unit area of the sheet compared to the first decorative layer portion. The non - existent region is located adjacent to the second decorative layer portion.

[0073] According to Mode 13, the non-existent region is located in the part of the decorative layer with a larger area, thereby being able to suppress the reduction in aesthetics caused by the decorative layer.

[0074] (Mode 14) Based on the aggregate of absorbent article packages described in any one of Modes 1 to 13, the plurality of absorbent article packages have a third absorbent article package. The third absorbent article package has other corresponding regions in the storage body corresponding to the first decorative layer existent regions. The other corresponding regions have a third decorative layer existent region where the decorative layer exists and other non-existent regions where the decorative layer does not exist. The relative position of the non-existent region of the second absorbent article package with respect to the storage body is different from the relative position of the other non-existent region of the third absorbent article package with respect to the storage body.

[0075] According to Mode 14, while a sense of unity is created among the three absorbent article packages, the user can appreciate the differences in the designs of the three absorbent article packages.

[0076] (Mode 15) Based on the aggregate of absorbent article packages described in Mode 14, the number of the non-existent regions is different from the number of the other non-existent regions.

[0077] According to Mode 15, while a sense of unity is created among the three absorbent article packages, the user can appreciate the differences in the designs of the three absorbent article packages.

[0078] (Mode 16) Based on the aggregate of absorbent article packages described in Mode 14 or 15, the area of the non-existent regions is different from the area of the other non-existent regions.

[0079] According to Mode 16, while a sense of unity is created among the three absorbent article packages, the user can appreciate the differences in the designs of the three absorbent article packages.

[0080] (Mode 17) Based on the aggregate of absorbent article packages described in any one of Modes 1 to 16, the plurality of absorbent article packages have a third absorbent article package. The third absorbent article package has other corresponding regions in the storage body corresponding to the first decorative layer existent regions. The other corresponding regions have a third decorative layer existent region where the decorative layer exists and other non-existent regions where the decorative layer does not exist. The weight of the adhesive layer per unit area of the non-existent regions is different from the weight of the adhesive layer per unit area of the other non-existent regions.

[0081] According to Mode 17, the depression condition with respect to the decorative layer varies in the non - existent area and other non - existent areas. Thus, the impression of the three - dimensional decoration is different, and the user can appreciate the difference in the design of the absorbent article package.

[0082] (Mode 18) Based on the aggregate of the absorbent article packages described in any one of Modes 1 to 17, the decorative layer is a layer formed of any one of a metal foil, a holographic foil, and a pigment foil.

[0083] According to Mode 18, the aesthetic property of the three - dimensional decorative layer can be improved. It can give the user who visually recognizes the decorative layer formed of a metal foil or a holographic foil the impression that the absorbent article is a high - quality product. On the other hand, the decorative layer formed of a pigment foil becomes a matte decoration with a dull finish, which can give the user the impression that the product has a stable sense of security.

[0084] === Embodiment ===

[0085] Hereinafter, taking a sanitary napkin as an example of the absorbent article, an aggregate of absorbent article packages of an individual package containing a plurality of absorbent articles will be described. The absorbent article is not limited to a sanitary napkin, and also includes disposable diapers of the underwear type or belt type, sanitary pads, panty liners, light incontinence pads, urine absorbent pads, breast pads, underarm sweat pads, disposable diapers for pets, and other absorbent articles.

[0086] << Basic Structure of Sanitary Napkin 1 >>

[0087] Figure 1 It is a top view obtained by observing Sanitary Napkin 1 in the unfolded state from the skin side. Figure 2 It is a schematic cross - sectional view of Sanitary Napkin 1. The unfolded Sanitary Napkin 1 has a length direction, a width direction, and a thickness direction that are orthogonal to each other. In the length direction, the side that abuts against the lower abdomen of the wearer is called the "front side", and the side that abuts against the buttocks of the wearer is called the "rear side". In addition, in the thickness direction of Sanitary Napkin 1, the side that abuts against the skin of the wearer is called the "skin side", and the opposite side is called the "non - skin side".

[0088] As Figure 2As shown, the sanitary napkin 1 has a topsheet 2, a middle sheet 3, an absorber 10, a backsheet 4, wing flaps 5, and side flaps 6. Adjacent materials in the thickness direction are joined and fixed using an adhesive such as a hot melt adhesive (not shown). The topsheet 2 and the middle sheet 3 are liquid-permeable sheet members, and examples thereof include non-woven fabric. The backsheet 4 is a liquid-impermeable sheet member, and examples thereof include a resin film. The side flaps 6 are folded back from the end portions in the width direction on the non-skin side of the absorber 10 toward the inside in the width direction so as to be located at the end portions in the width direction on the skin side of the topsheet 2. The backsheet 4 and the wing flaps 5 project outward in the width direction with respect to the side flaps 6, and a wing portion 1w is formed at the central portion in the length direction of the sanitary napkin 1.

[0089] In addition, the topsheet 2 that comes into contact with the skin of the wearer may also be a sheet made of cotton, which is a natural fiber (for example, a sheet member formed of 100% cotton, a mixed sheet of cotton and air-through non-woven fabric, etc.). In this way, irritation to the skin of the wearer can be reduced. In this case, as shown in the drawings described later, by providing a pattern indicating cotton on the sanitary napkin 1, the individual package 30, and the package body 40, the use of cotton can be shown to the user. However, the topsheet 2 may not be a cotton sheet.

[0090] The absorber 10 is a member that absorbs and holds excrement inside. Figure 2 The absorber 10 has an absorbent core 11 and a core wrap sheet 12 that covers the absorbent core 11. The absorbent core 11 is formed into a predetermined shape from pulp fibers, which are liquid-absorbent fibers, cellulose-based absorbent fibers, etc. The core wrap sheet 12 is a liquid-permeable sheet member, and examples thereof include cotton paper. However, the structure of the absorber 10 is not limited to the above structure. For example, it may also be a SAP sheet in which a SAP layer is attached to a hydrophilic sheet, an air-laid sheet in which liquid-absorbent fibers are formed into a sheet shape by the air-laying method, etc. In addition, the sanitary napkin 1 has a compression portion 20 formed by compressing the absorber 10 along the thickness direction from the skin side of the topsheet 2.

[0091] The basic structure of the sanitary napkin 1 has been described above, but the structure of the sanitary napkin is not limited to the above structure. For example, it may also be a sanitary napkin that does not have a wing portion 1w.

[0092] <<Individual Package 30 of Sanitary Napkin>>

[0093] Figure 3 is a top view obtained by observing the individual package 30 of the sanitary napkin in the unfolded state from the non-skin side. Figure 4 is a top view obtained by observing the individual package 30 of the sanitary napkin during the unfolding process from the skin side. Figure 5 is a top view of the individual package 30 of the sanitary napkin.

[0094] The individual package 30 of the sanitary napkin 1 (hereinafter also referred to as "individual package 30") is formed by individually packaging the sanitary napkin 1 with a packaging sheet 31, and includes the sanitary napkin 1, the packaging sheet 31, the fixing band 32, and the release sheets 33 and 34. The packaging sheet 31 is a rectangular sheet member, and examples thereof include a resin film, a non-woven fabric, paper, and a sheet formed by laminating and combining the above materials. The length direction of the packaging sheet 31 corresponds to the length direction of the sanitary napkin 1, and the transverse direction as the short side direction of the packaging sheet 31 corresponds to the width direction of the sanitary napkin 1. The fixing band 32 is provided at the end in the length direction of the packaging sheet 31.

[0095] As Figure 3 shown, on the non-skin side of the sanitary napkin 1 (i.e., the non-skin side of the bottom sheet 4), a plurality of adhesive portions 8 and 9 formed by coating an adhesive or the like are provided. In the main body portion of the sanitary napkin 1, a plurality of rectangular adhesive portions 8 extending in the length direction are arranged in the width direction. The adhesive portions 8 in the main body portion are used to fix the main body portion of the sanitary napkin 1 to the inner side of the underwear of the wearer. In addition, in the wing portion 1w, a plurality of rectangular adhesive portions 9 extending in the length direction are also arranged in the width direction. When the sanitary napkin 1 is worn, the wing portion 1w is bent and fixed to the outer side of the underwear by the adhesive portion 9. In addition, the shape, number, and arrangement of the adhesive portions 8 and 9 are not limited to Figure 3 the case exemplified.

[0096] In the individual package 30, the non-skin side of the sanitary napkin 1 is fixed to the packaging sheet 31 via the release sheet 33. The release sheet 33 covers the adhesive portion 8 of the main body portion of the sanitary napkin 1 and enables the sanitary napkin 1 to be easily peeled off when the individual package 30 is opened. In addition, as Figure 4 shown, the wing portion 1w is folded inward in the width direction on the skin side of the sanitary napkin 1. The adhesive portion 9 of the wing portion 1w is covered by the release sheet 34. In addition, the sanitary napkin 1 may be directly fixed to the packaging sheet 31 in a peelable manner instead of being fixed to the packaging sheet 31 via the release sheet 33.

[0097] The packaging sheet 31 and the sanitary napkin 1 are folded at two folding portions F1 and F2 along the transverse direction from Figure 4 the state. The transverse end portions of the packaging sheet 31 folded together with the sanitary napkin 1 are joined to form a joint portion 35 as Figure 5 shown. As the joining method at the joint portion 35, known joining methods such as heat sealing, ultrasonic sealing, an adhesive, and a combination of the above methods can be exemplified. In addition, the fixing band 32 is provided across the opening end of the packaging sheet 31. The user holds the fixing band 32 and unfolds the folding portions F1 and F2 to open the individual package 30.

[0098] As described above, the independent package 30 of the sanitary napkin has been described, but the structure of the independent package 30 is not limited to the above structure. For example, the number of the folding parts F1 and F2 of the packaging sheet 31 is not limited to two, and may be one, or may be three or more. In addition, it may be that the packaging sheet 31 and the sanitary napkin 1 are folded not only at the folding parts F1 and F2 along the transverse direction, but also at the folding parts along the longitudinal direction. In addition, the packaging sheet 31 and the sanitary napkin 1 may be folded independently. That is, the packaging sheet 31 may be folded so as to internally package the pre-folded sanitary napkin 1.

[0099] <<Encapsulation 40 of Sanitary Napkin>>

[0100] Figure 6A is a perspective view of the encapsulation 40 of the sanitary napkin, Figure 6B is a view showing a state where the storage body 41 is opened. The encapsulation 40 of the sanitary napkin (the absorbent article encapsulation, hereinafter also referred to as "encapsulation 40") has a storage body 41 and the independent packages 30 of a plurality of sanitary napkins stored in the storage body 41.

[0101] Figure 6A The illustrated storage body 41 has an up-down direction, a left-right direction, and a front-back direction, and has a rectangular parallelepiped-shaped main body portion 42 and a sealing member 43. The sealing member 43 is provided on the back surface 41B of the encapsulation 40 (storage body 41). Specifically, the sealing member 43 is provided at the upper part of the rear side of the storage body 41. A pinch portion 431 is provided at the center in the left-right direction of the sealing member 43. In addition, a cut line 44 (for example, a tear line) is formed at a portion of the main body portion 42 covered by the sealing member 43. The user pinches the pinch portion 431 and pulls the sealing member 43, so that as Figure 6B shown, a part of the main body portion 42 is adhered to the sealing member 43 along the cut line 44 to open, and an opening portion 45 serving as an outlet for the sanitary napkin 1 is formed.

[0102] In addition, Figure 6A the shape and structure of the illustrated storage body 41 are an example and are not limited thereto. For example, it may be a rectangular parallelepiped-shaped storage body without a sealing member 43, a self-standing bag type, a flat bag, or the like.

[0103] <<Aggregate 100 of Absorbent Article Encapsulations>>

[0104] Figure 7 is a schematic perspective view of the aggregate 100 of the absorbent article encapsulations.

[0105] The aggregate 100 of the absorbent article encapsulations includes a plurality of encapsulations 40 and a bundling member 101 for bundling the plurality of encapsulations 40. As the bundling member 101, a corrugated cardboard box is illustrated here, but it is not limited thereto. In Figure 7In this case, the packages 40 are bundled by the bundling package 101 in a state of being arranged in 4 rows × 8 columns, but the number of the packages 40 bundled by the bundling package 101 is not particularly limited as long as it is plural. Figure 7 The corrugated cardboard box shown is in an open state, but actually, the aggregate of the absorbent article packages is shipped from the factory to stores and the like in a state where the corrugated cardboard box is sealed. In the following description, the aggregate of the absorbent article packages is also referred to as the package group 100.

[0106] ===First Embodiment===

[0107] Figure 8A and Figure 8B are front views of the first package 401 and the second package 402. Figure 9A , Figure 9B , Figure 10A and Figure 10B are diagrams for explaining the decorative sheet 50.

[0108] The storage body 41 (specifically, the main body portion 42) of the sanitary napkin package 40 of the present embodiment has a decorative sheet 50 to which decoration is applied. As Figure 9A shown, the decorative sheet 50 has: a sheet 51; an adhesive layer 52 provided on the surface of the sheet 51; and a decorative layer 53 provided on the adhesive layer 52 and having a maximum thickness of 10 μm or less. As the decorative layer 53, metal foil, holographic foil, pigment foil, etc. can be exemplified (details will be described later).

[0109] The decorative layer 53 is provided at a position visually recognizable by the user and protrudes from the surface of the sheet 51 in the thickness direction of the sheet 51. That is, the decorative layer 53 protrudes from the surface of the surrounding sheet 51 by the adhesive layer 52 formed so as to bulge on the surface of the sheet 51. Therefore, the decoration exhibited by the decorative layer 53 is visually recognized by the user as a three-dimensional decoration. In the following description, the portion where the decorative layer 53 overlaps with the adhesive layer 52 is also referred to as the "three-dimensional decoration portion 54". As the cross-sectional shape of the three-dimensional decoration portion 54, Figure 9A , Figure 9B , Figure 10A and Figure 10B shown shapes can be exemplified. As Figure 9A , Figure 9B , Figure 10A shown, the portion (52E) of the adhesive layer 52 that does not overlap with the decorative layer 53 is not included in the three-dimensional decoration portion 54.

[0110] In the present embodiment, a three-dimensional decoration portion 54 (adhesive layer 52 + decorative layer 53) is provided on the outer side surface of the storage body 41 of the package 40, and the three-dimensional decoration portion 54 protrudes toward the outside of the storage body 41. In Figure 8A and Figure 8BIn the example where the three-dimensional decoration part 54 is provided on the front surface 41F of the storage body 41, the three-dimensional decoration part 54 is represented by black filling. The outline of the flower and the pattern of the petals are presented through the three-dimensional decoration part 54.

[0111] In this way, even when the sheet 51 is decorated with a relatively thin decorative layer 53 (such as a metal foil, a holographic foil, a pigment foil, etc.) with a maximum thickness of 10 μm or less, by providing the decorative layer 53 on the adhesive layer 52, a three-dimensional decoration (three-dimensional decoration part 54) can be formed. A user who visually recognizes the three-dimensional decoration part 54 provided on the storage body 41 of the package 40 is likely to receive the impression of a three-dimensional product. Therefore, the user is also likely to have the impression that the sanitary napkin 1 stored in the storage body 41 is a product that is three-dimensionally deformed and conforms to the body to prevent leakage.

[0112] The type of decoration presented by the three-dimensional decoration part 54 is not particularly limited, and examples include characters, numbers, marks (such as musical note marks, signs, etc.), graphics (such as circles, polygons, hearts, stars, etc.), patterns (such as pictures representing the shapes of objects, animals, plants, people, etc.), geometric patterns, colors (parts having a predetermined color difference from the color of the sheet 51), or decorations formed by combining the above decorations. Figure 8A and Figure 8B The three-dimensional decoration part 54 shown is an example, and the shape, number, size, and arrangement of the three-dimensional decoration part 54 are not particularly limited.

[0113] The adhesive layer 52 is a layer formed of a raw material that maintains a raised state on the surface of the sheet 51 and has adhesiveness for bonding the sheet 51 and the decorative layer 53. As the raw material for forming the adhesive layer 52, an example is a colorless and transparent ultraviolet curable adhesive. Ultraviolet rays are irradiated on the adhesive layer 52, which is an ultraviolet curable adhesive, and the adhesiveness of the partially cured adhesive layer 52 is used to bond the decorative layer 53 to the adhesive layer 52. However, it is not limited thereto. For example, other photo-curable adhesives, etc. may also be used. It is preferable to adjust the viscosity, etc. of the adhesive layer 52 so that the adhesive layer 52 does not easily penetrate into the sheet 51 and remains raised on the sheet 51. In addition, as the sheet 51 constituting the decorative sheet 50, examples include resin films, non-woven fabrics, papers, and sheets formed by laminating and combining the above materials.

[0114] The thickness of the decorative layer 53 is the length in the direction orthogonal to the surface of the decorative layer 53 (for example Figure 9ARegarding its maximum thickness (less than 10 μm), it can be confirmed by a known method. For example, determine the part of the decorative sheet 50 (here, the storage body 41) where the three-dimensional decorative part 54 is formed, and cut this part at multiple arbitrary places to form multiple samples. Then, use an optical microscope (such as VHX-900F manufactured by Keyence Corporation, etc.) to magnify and photograph the cut surface of each sample. For each photographed cut surface image, measure the maximum thickness of the decorative layer 53. Set the maximum value of the maximum thickness of each sample as the maximum thickness of the decorative layer 53, and confirm that it is less than 10 μm.

[0115] The encapsulation body group 100 ( Figure 7 ) includes multiple encapsulation bodies 40 having Figure 8A the first encapsulation body 401 (the first absorbent article encapsulation body) shown in Figure 8B and the second encapsulation body 402 (the second absorbent article encapsulation body) shown in. The first encapsulation body 401 has a "first decorative layer existing area R1" where the decorative layer 53 exists in the storage body 41. On the other hand, the second encapsulation body 402 has a "corresponding area Rc" corresponding to the first decorative layer existing area R1 in the storage body 41.

[0116] In addition, set the same position of the storage body 41 of each encapsulation body 40 as the "reference position O". For example, set the position at the lower end in the vertical direction and the left end in the horizontal direction of the front surface 41F where the three-dimensional decorative part 54 is provided in the storage body 41 as the reference position O. The "corresponding area Rc" is an area where, when applying the positional relationship of the decorative layer 53 of the storage body 41 of the first encapsulation body 401 with respect to the reference point O to the storage body 41 of the second encapsulation body 402, the same positional relationship is obtained with respect to the reference point O of the second encapsulation body 402.

[0117] Moreover, the corresponding area Rc of the second encapsulation body 402 has a "second decorative layer existing area R2" where the decorative layer 53 exists in the same manner as the first encapsulation body 401 and a "non-existing area RN" where the decorative layer 53 does not exist. That is, in the first encapsulation body 401 and the second encapsulation body 402, the configuration of the decorative layer 53 is locally different only in terms of the non-existing area RN.

[0118] Specifically, in the first encapsulation body 401, when the decorative layer 53 exists in an area offset by a certain length (example: offset by length X to the right and length Y upward) from the reference point O, this area is the first decorative layer existing area R1. In the second encapsulation body 402, when the decorative layer 53 exists in the corresponding area Rc, which is the area offset by the same length (example: offset by length X to the right and length Y upward) from the reference point O, this area is the second decorative layer existing area R2, and when the decorative layer 53 does not exist, this area is the non-existing area RN.

[0119] Thus, preferably, the package group 100 includes the first package 401 and the second package 402 with locally different configurations of the decorative layer 53. In this way, the locally different designs of the multiple packages 40 included in the package group 100 can prevent monotonous decoration. Thereby, when a user visually recognizes the first package 401 and the second package 402 in a store, their own bathroom, etc., they can appreciate the design differences. Therefore, not only can the interest level of ordinary flat printing based on ink be further improved, but also the interest level of three-dimensional decoration using a relatively thin decorative layer 53 can be further enhanced. In addition, the user can identify the first package 401 and the second package 402 based on the presence or absence of the non-existence region RN. For example, the package 40 being used can be quickly identified.

[0120] In addition, assuming that the corresponding region Rc of the second package 402 does not have the second decorative layer presence region R2, the configuration of the decorative layer 53 is very different. In this case, there is a possibility that the user may wonder whether the same product is stored in the two packages. In contrast, the corresponding region Rc of the second package 402 in the present embodiment has the second decorative layer presence region R2. Thereby, a sense of unity is created between the first package 401 and the second package 402, and the user can unhesitatingly identify the situation where the same product is stored in the two packages (401, 402).

[0121] Figure 9A , Figure 10A and Figure 10B are cross-sectional views of the three-dimensional decorative portion 54 that is not adjacent to the non-existence region RN. Figure 9B is a cross-sectional view of the three-dimensional decorative portion 54 that is adjacent to the non-existence region RN. In Figure 9B , there is an adhesive layer 52 in the non-existence region RN, and the decorative layer 52 and the adhesive layer 52 with different textures can be visually recognized on the surface of the three-dimensional decoration. Thereby, the user receives different impressions from the three-dimensional decorative portion 54 adjacent to the non-existence region RN and the three-dimensional decorative portion 54 not adjacent to the non-existence region RN. For example, when using a decorative layer 53 with a metallic luster, the way of light reflection is different depending on the presence or absence of the non-existence region RN, and the impression changes. Therefore, the user can further appreciate the differences in the three-dimensional decoration. However, it is not limited to the above structure, and it may be that there is no adhesive layer 52 in the non-existence region RN.

[0122] In addition, the non-existence region RN is adjacent to the three-dimensional decorative portion 54, thereby forming unevenness on the surface, and the three-dimensional decorative portion 54 is visually recognized more three-dimensionally. Therefore, it is possible to further give the user the impression that the sanitary napkin 1 stored in the package 40 is also a product that is easily three-dimensionally deformable and conformable.

[0123] Alternatively, it may be that, as Figure 9A and Figure 10A shown, there is no decorative layer 53 at the outer edge portion of the adhesive layer 52. That is, it may also be that the adhesive layer 52 has a protruding portion 52E that protrudes to one side in a predetermined direction with respect to the decorative layer 53. The adhesive layer 52 may protrude to both sides in the predetermined direction as shown in the figure, or may protrude only to one side in the predetermined direction. The region where the decorative layer 53 does not exist in the adhesive layer 52 of the second package 402 corresponds to the protruding portion 52E or the non-existence region RN. That is, when the decorative layer 53 exists in the corresponding region of the first package 401, it corresponds to the non-existence region RN, and when the decorative layer 53 does not exist in the corresponding region of the first package 401, it corresponds to the protruding portion 52E. In addition, for the non-existence region RN, all of its outer periphery may be surrounded by the decorative layer 53, or a part of the outer periphery of the non-existence region RN may be adjacent to the adhesive layer 52 (protruding portion 52E).

[0124] In addition, when an external force acts on the decorative sheet 50 (here, the storage body 41), the force is easily applied to the protruding portion 52E which is the end portion of the adhesive layer 52. However, since the adhesive layer 52 is formed of an adhesive raw material and has elasticity, it is easily deformed following the sheet 51. Therefore, the situation where the adhesive layer 52 peels off from the sheet 51 can be suppressed. In particular, the maximum thickness t1 of the protruding portion 52E of the adhesive layer 52 is smaller than the maximum thickness t2 of the portion of the adhesive layer 52 that overlaps with the decorative layer 53 (t1 < t2), so that the protruding portion 52 is more easily deformed following the sheet 51. In addition, the decorative layer 53 is not located at the end portion where the force is easily applied, so that the peeling between the adhesive layer 52 and the decorative layer 53 and the cracking of the decorative layer 53 can be suppressed. A user who visually recognizes the three-dimensional decorative portion 54 with maintained quality is likely to have the impression that the sanitary napkin 1 is also a high-quality product.

[0125] In addition, preferably, the length L1 of the protruding portion 52E in the predetermined direction is shorter than the length L2 of the portion of the adhesive layer 52 that overlaps with the decorative layer 53 in the predetermined direction (L1 < L2). By not making the protruding portion 52E unnecessarily long, the situation where the aesthetic property (such as metallic luster) generated by the decorative layer 53 is reduced can be prevented. However, it is not limited to the above situation, and it may also be that, as Figure 10B shown, the adhesive layer 52 does not have the protruding portion 52E.

[0126] In addition, preferably, the decorative layer 53 is a layer formed of any one of a metal foil, a holographic foil, and a pigment foil. In this way, the aesthetic property of the three-dimensional decorative portion 54 can be improved. Specifically, the three-dimensional decorative portion 54 formed of a metal foil or a holographic foil is presented in a color with a metallic luster such as gold or silver, and is easily noticeable. As a result, a user who visually recognizes the storage body 41 of the package 40 is likely to focus on the glittering three-dimensional decorative portion 54, and is also likely to have an impression that the sanitary napkin 1 is three-dimensionally deformed. In addition, due to the three-dimensional decorative portion 54 having a metallic luster, the user is also likely to receive an impression that the product is high-class. Therefore, the user is likely to have an impression that the sanitary napkin 1 stored in the storage body 41 is also a high-quality product (for example, less likely to leak and comfortable to wear), and can use the sanitary napkin 1 with confidence. On the other hand, the three-dimensional decorative portion 54 formed of a pigment foil becomes a dull matte decoration, and can give the user an impression that the product has a stable sense of security. In addition, since there is no metallic luster, the user is likely to have a sense of security that no foreign matter such as metal is mixed in the stored sanitary napkin 1.

[0127] Examples of the metal foil include a metal foil obtained by beating a metal to thinly and flatly extend it, a thin and flat sheet containing a metal (a coating film of a metal powder pigment, a metal evaporation film), and a sheet obtained by laminating a synthetic resin layer on the above member. Examples of the metal contained in the metal foil include gold, silver, copper, tin, brass, aluminum, and the like.

[0128] The holographic foil is a thin and flat sheet having a property of reflecting incident light as a color by using a prism effect. By providing a fine concavo-convex pattern on the surface, a person who sees the reflected light can visually recognize a specific pattern.

[0129] Examples of the pigment foil include a sheet formed by laminating a coating film of a pigment on a synthetic resin layer. Examples of the color of the pigment include red, blue, yellow, black, white, etc., and there is no particular limitation. In addition, the decorative layer 53 may also be a foil material other than a metal foil, a holographic foil, and a pigment foil.

[0130] Figure 11A is an enlarged view of a part of the first package 401, Figure 11B is an enlarged view of a part of the second package 402. Figure 12 is an explanatory diagram of the deviation amount of the individual package 30. Figure 13A - Figure 13C is an explanatory diagram of the folding method of the short-pant type sanitary napkin 80. Figure 14 is a top view of the individual package 30 of the short-pant type sanitary napkin 80. The individual package 30 has a lateral direction along the opening end 30O and a longitudinal direction orthogonal to the lateral direction.

[0131] As Figure 12As shown, in the individual package 30, the length obtained by subtracting the maximum lateral length W2 of the internal sanitary napkin 1 from the maximum lateral length W1 in the lateral direction is defined as the "first length" (= W1 - W2). And for each of the multiple individual packages 30 (here, 10 individual packages 30) stored in the second package 402 having the non - existent region RN, the first length is obtained. Among the first lengths of the multiple individual packages 30, the difference between the maximum value and the minimum value of the first length is defined as the "first deviation amount" (= Max(W1 - W2) - Min(W1 - W2)). At this time, preferably, the diameter D1 of the circumscribed circle 81 circumscribing the non - existent region RN (refer to Figure 11B ) is smaller than the first deviation amount.

[0132] The first length corresponds to the lateral blank space of the packaging sheet 31 of the individual package 30. Among the multiple individual packages 30 stored in the package 40, the blank spaces of the packaging sheets 31 are uneven due to manufacturing errors, resulting in the first deviation amount. However, this deviation is small and can be suppressed to such a small extent that the user does not feel a sense of disharmony that the multiple individual packages 30 are the same product. Therefore, by making the length of the non - existent region RN smaller than the first deviation amount, the user is less likely to feel a sense of disharmony with the non - existent region RN. Thus, the user can feel a sense of unity from the first package 401 and the second package 402 while appreciating the small differences in design. In addition, by moderately suppressing the length of the non - existent region RN, the area of the decorative layer 53 can be ensured. Thus, it is possible to prevent a decrease in aesthetics (such as a metallic luster) caused by the decorative layer 53.

[0133] In the present embodiment, as the absorbent article, a sanitary napkin 1 of the type adhered to underwear is exemplified, but the absorbent article may also be a short - type sanitary napkin 80. When packaging, the parts on both outer sides in the left - right direction of the short - type sanitary napkin 80 relative to the absorbent main body 81 are mostly folded at the folding part F1 ( Figure 13A ) and then folded in half in the up - down direction ( Figure 13B ). In Figure 14 , the folded short - type sanitary napkin 80 is wrapped in the packaging sheet 31 with the longitudinal direction of the individual package 30 along the left - right direction of the short - type sanitary napkin 80.

[0134] Also in the individual package 30 of the above - mentioned short - type sanitary napkin 80, the length obtained by subtracting the maximum lateral length W2 of the internal short - type sanitary napkin 80 from the maximum lateral length W1 in the lateral direction is defined as the "first length" (= W1 - W2). In addition, the folding method and packaging method of the above - mentioned short - type sanitary napkin 80 are just examples and are not limited thereto.

[0135] In addition, the size of the non - existent region RN is preferably as follows. AsFigure 12 As shown, in the individual package 30, the longitudinal length L2 from the opening end 30O (the end of the packaging sheet 31) at the central position CL in the transverse direction to the inner sanitary napkin 1 is defined as the "second length L2". The inner sanitary napkin 1 refers to the end 1a of the sanitary napkin 1 located on the side of the opening end 30O in the thickness direction of the individual package 30, that is, the end 1a of the sanitary napkin 1 folded at the folding portion F1. And, among the second lengths L2 of the individual packages 30 stored in the second package 402, the difference between the maximum value and the minimum value of the second length L2 is defined as the "second deviation amount" (= Max(L2) - Min(L2)). At this time, preferably, the diameter D1 of the circumscribed circle 81 circumscribing the non - existent region RN is smaller than the second deviation amount.

[0136] The second length L2 corresponds to the longitudinal blank space of the packaging sheet 31 from the opening end 30O of the individual package 30 to the sanitary napkin 1. Among the individual packages 30 stored in the package 40, the blank spaces of the packaging sheets 31 have unevenness due to manufacturing errors, resulting in the second deviation amount. However, this deviation is small and can be suppressed to such an extent that the user does not feel a sense of disharmony that the individual packages 30 are the same product. Therefore, by making the length of the non - existent region RN smaller than the second deviation amount, the user is less likely to feel a sense of disharmony with the non - existent region RN. Thus, the user can feel a sense of unity from the first package 401 and the second package 402 while appreciating the small differences in design. In addition, the area of the decorative layer 53 can be ensured, preventing the aesthetic reduction caused by the decorative layer 53.

[0137] At both transverse ends (joint portions 35) along the opening end 30O of the individual package 30, the folded packaging sheets 31 are joined to each other by a plurality of welding portions 36. Preferably, the area of the non - existent region RN is smaller than the minimum value of the areas a36 of the plurality of welding portions 36 provided in a certain individual package 30 included in the second package 402. A certain individual package 30 is any one of the plurality of individual packages 30 included in the second package 402.

[0138] The area a36 of the welded portion 36 is large enough for the user to recognize, but since the sanitary napkin 1 occupies most of the independent package 30, the area of the welded portion 36 is relatively small. Therefore, by making the area of the non - existent region RN smaller than the area of the welded portion 36, it is less likely for the user to have a sense of disharmony with the non - existent region RN. Thus, the user can feel a sense of unity from the first package 401 and the second package 402 while appreciating the small differences in design. In addition, the area of the decorative layer 53 can be ensured, preventing a reduction in aesthetics caused by the decorative layer 53. The area of each region can be calculated using ordinary image analysis software and area calculation software.

[0139] In addition, in a certain independent package 30 included in the second package 402, the maximum value and the minimum value of the interval W3 between the welded portions 36 adjacent in the horizontal direction are obtained. As Figure 12 shown, the interval W3 is the length between the side ends of the welded portions 36 adjacent in the horizontal direction. The difference between the maximum value and the minimum value of the intervals W3 of the multiple welded portions 36 provided in a certain independent package 30 is defined as the third deviation amount ( = Max(W3)-Min(W3)). At this time, preferably, the diameter D1 of the circumscribed circle 81 circumscribing the non - existent region RN is larger than the third deviation amount.

[0140] The welded portion 36 is formed using a roller or the like having an uneven pattern on its surface. Thus, the deviation (the third deviation amount) of the intervals W3 between the welded portions 36 is small enough that the user will not notice. Therefore, preferably, the length of the non - welded region RN is small enough that the user will not have a sense of disharmony as described above, and is larger than the deviation of the intervals W3 between the welded portions 36 to make the user notice. In this way, the user can appreciate the small differences in the designs of the first package 401 and the second package 402 and the difference in the impression of three - dimensional decoration caused by the presence or absence of the non - existent region RN.

[0141] Figure 15 is a schematic cross - sectional view of the storage body 41. Figure 16 is a top view of the independent package 30. As Figure 15 shown, the storage body 41 has a stacking direction in which a plurality of independent packages 30 are stacked along its thickness direction. In the package 40 of the present embodiment, the front - to - back direction (the direction passing through the front surface 41F and the back surface 41B of the storage body 41) of the storage body 41 becomes the stacking direction. In the second package 402, when the non - existent region RN is located on the surface (here, the front surface 41F) of the storage body 41 orthogonal to the stacking direction, the following is preferable.

[0142] As Figure 16As shown, the individual package 30 has an article presence portion R30 where the sanitary napkin 1 is present and a non-article presence portion R30n where the sanitary napkin 1 is not present. The non-article presence region RN of the second packaging body 402 preferably overlaps with the article presence portion R30 of at least one of the plurality of individual packages 30 in the storage body 41 in the stacking direction. Preferably, it preferably overlaps with the plurality of article presence portions R30, and more preferably, it preferably overlaps with all of the article presence portions R30.

[0143] The thickness of the article presence portion R30 of the independent package body 30 is greater than the thickness of the non-article presence portion R30n. Therefore, in the central portion of the left-right direction of the storage body 41, the article presence portion R30 is stacked and the thickness becomes larger, and the sheet 51 forming the storage body 41 is in an extended state. If the non-existence area RN is located at this position, the non-existence area RN extends to the outside of the storage body 41 and is easily recognized by the user. As a result, the user can appreciate the small difference in the design of the first package body 401 and the second package body 402, and the difference in the impression of the three-dimensional decoration caused by the presence or absence of the non-existence area RN.

[0144] The individual package 30 contains the folded sanitary napkin 1 and has a maximum stacking portion 11A where the number of stacked folded absorbent cores 11 is the largest. Figure 4 The absorbent core 11 is folded at the two folded portions F1 and F2 shown, and the central portion in the longitudinal direction of the absorbent core 11 overlaps with the upper end portion folded at the folded portion F1 of the absorbent core 11 and the lower end portion folded at the folded portion F2 of the absorbent core 11, and is stacked in three layers. The portion stacked in three layers becomes the maximum stacking portion 11A. The maximum stacking portion 11A has the largest thickness in the independent package 30. Therefore, it is preferable that the non-existence area RN of the second package 402 overlaps with the maximum stacking portion 11A of all the independent packages 30 in the stacking direction.

[0145] Thus, the non-existence region RN is located at a portion where the thickness of the storage body 41 in the stacking direction is the largest and the sheet 51 forming the storage body 41 is most extended. Therefore, the non-existence region RN further extends outside the storage body 41 and is easily recognized by the user.

[0146] However, it is not limited to the above structure. The independent package 30 has a minimum stacking part 11B with the smallest number of stacking of the folded absorbent core 11. In the sanitary napkin 1 of the present embodiment, the absorbent cores 11 are not stacked on each other at the narrowed part of the absorbent core 11 but form a layer, which becomes the minimum stacking part 11B. The thickness of the minimum stacking part 11B is smaller than the thickness of the maximum stacking part 11A. It can also be that the non-existence area RN of the second package 402 overlaps with the minimum stacking part 11B of all the independent packages 30 in the stacking direction.

[0147] Inside the storage body 41, for the part where the minimum stacked part 11B of the absorbent core 11 is stacked, the sheet 51 has less stretching compared to the part where the maximum stacked part 11A is stacked, but has stretching compared to the part where the non-item presence part R30n is stacked. That is, the non-presence area RN is located at the part where the sheet 51 stretches moderately. In this case, the non-presence area RN is easily recognizable by the user, and it is possible to suppress the opening of the non-presence area RN due to the sheet 51 stretching and bulging outwardly. Therefore, it is easy to maintain the unevenness of the surface generated by the decorative layer 53 and the non-presence area RN.

[0148] In addition, not limited to the above structure, it may be that the non-presence area RN of the second package body 402 overlaps with the non-item presence parts R30n of all the individual packages 30 in the stacking direction. Inside the storage body 41, the non-item presence parts R30n are stacked at the end portions in the left-right direction, and the sanitary napkin 1 does not exist, and the thickness is thinner compared to the central portion in the left-right direction. Thus, as Figure 15 shown, the front surface 41F of the storage body 41 inclines downward from the central portion in the left-right direction toward the end portions. The non-presence area RN is located at the inclined part of the sheet 51, so that when the user visually recognizes the front surface 41F of the storage body 41 along the stacking direction, it is easy to notice the depression of the non-presence area RN. Thus, the user can appreciate the difference in the impression of the three-dimensional decoration generated by the presence or absence of the non-presence area RN.

[0149] In addition, as Figure 8B shown, the decorative layer 53 of the second package body 402 has a first decorative layer part 531 and a second decorative layer part 532. The second decorative layer part 532 has a larger area of the decorative layer 53 per unit area of the sheet 51 compared to the first decorative layer part 531. In addition, the first decorative layer part 531 and the second decorative layer part 532 may be parts of a continuous decorative layer 53 (for example, a decorative layer 53 forming the same pattern) or parts of a separated decorative layer 53 (for example, a decorative layer 53 forming a separate pattern). And preferably, the non-presence area RN is located at a position adjacent to the second decorative layer part 532 having a higher area ratio of the decorative layer 53.

[0150] In Figure 8B there is a non-presence area RN at the part where the outline of the flower and the pattern of the petals of the decorative layer 53 are continuous (the second decorative layer part 532). The part of this decorative layer 53 has a larger area of the decorative layer 53 per unit area of the sheet 51 compared to, for example, the part where only the pattern of the petals is present (the first decorative layer part 531). In this way, it is preferable that the non-presence area RN is located at a position adjacent to the part having a larger area of the decorative layer 53. In this way, even if there is no decorative layer 53 in the non-presence area RN, the user is less likely to have a sense of incongruity, and in addition, it is possible to prevent the aesthetic property from being reduced due to the decorative layer 53.

[0151] Figure 17A and Figure 17B is the front view of the package body 40. In the package body group 100 shown in Figure 7 In the package body group 100 shown in

[0152] And preferably, as shown in Figure 17A and Figure 17B shown, the relative position of the non - existent region RN of the second package body 402 with respect to the storage body 41 is different from the relative position of the other non - existent region RN3 of the third package body 403 with respect to the storage body 41. That is, it is preferable that the position of the non - existent region RN with respect to the reference position O of the storage body 41 is different from the position of the other non - existent region RN3 with respect to the reference position O.

[0153] In this way, when the user visually recognizes the first package body 401 to the third package body 403, the configuration of the decorative layer 53 is slightly different, and small differences in the design can be appreciated. Also, in the third package body 403, the three - dimensional decorative part 54 adjacent to the other non - existent region RN3 can be more three - dimensionally visually recognized, or the impression of the three - dimensional decoration can be changed according to the presence or absence of the other non - existent region RN3.

[0154] Moreover, it is preferable that the number of non - existent regions RN of the second package body 402 is different from the number of other non - existent regions RN3 of the third package body 403. For example, in Figure 17A and Figure 17BIn this case, the second package 402 has a non-existent region RN, and the third package 403 has three other non-existent regions RN3. In this way, there are multiple parts with different configurations of the decorative layer 53, so that the user can easily recognize the differences in the three-dimensional decorative designs and appreciate the small differences in the designs.

[0155] In addition, preferably, the area of the non-existent region RN of the second package 402 is different from the area of the other non-existent regions RN3 of the third package 403. For example, Figure 17B as shown, the third package 403 has other non-existent regions RN3 with an area larger than the area of the non-existent region RN of the second package 402 and other non-existent regions RN3 with an area smaller than the area of the non-existent region RN of the second package 402.

[0156] In this way, the user can easily recognize the differences in the three-dimensional decorative designs and appreciate the small differences in the designs. In addition, since the area of the non-existent region RN is different from the area of the other non-existent regions RN3, the impression of the three-dimensional decoration also changes, and the user can further appreciate the design differences.

[0157] In addition, preferably, the weight of the adhesive layer 502 per unit area of the non-existent region RN of the second package 402 is different from the weight of the adhesive layer 52 per unit area of the other non-existent regions RN3 of the third package 403.

[0158] In this way, in the non-existent region RN and the other non-existent regions RN3, the depression of the adhesive layer 52 with respect to the adjacent decorative layer 53 can be made different. As a result, the impression of the three-dimensional decoration changes, and the user can further appreciate the design differences.

[0159] In addition, the three-dimensional decoration part 54 can be provided at any position on the outer side surface of the housing 41 of the package 40. Preferably, the three-dimensional decoration part 54 is provided on the front surface (front face) 41F of the housing 41 of the package 40. In this way, the three-dimensional decoration part 54 is easily visually recognized by the user in a store or the like. In addition, as the front surface of the housing 41, the largest surface among the multiple surfaces of the housing 41, the surface on which the sales name (brand name), the storage quantity, etc. are largely recorded can be exemplified.

[0160] In addition, in the case of the package body 40 having the sealing member 43, it is preferable that the sealing member 43 is provided on the back surface 41B of the housing body 41 of the package body 40, and the three-dimensional decoration portion 54 is not provided on the back surface 41B of the housing body 41. When opening the sealing member 43, the user holds the back surface 41B of the housing body 41, or the pulling force of the sealing member 43 acts on the back surface 41B of the housing body 41. Therefore, by not providing the three-dimensional decoration portion 54 on the back surface 41B (the opening surface) of the housing body 41, it is possible to prevent the three-dimensional decoration portion 54 from falling off and adhering to the user or the sanitary napkin 1 during opening.

[0161] In addition, it is preferable that the maximum thickness of the adhesive layer 52 is larger than the maximum thickness of the decorative layer 53. For example, it is preferable that the thickness of the adhesive layer 52 is in the range of about 10 to 80 μm and the thickness of the decorative layer 53 is in the range of about 4 to 6 μm. In this way, the decorative layer 53 with a thinner thickness can protrude further from the surface of the surrounding sheet 51. Therefore, the three-dimensional decoration portion 54 becomes more three-dimensional, and it is easier for the user to recognize the case where a three-dimensional decoration is provided. In addition, as described above, the thickness of the decorative layer 53 (for example Figure 9A of 53t) is set to the length in the direction orthogonal to the surface of the decorative layer 53. The thickness of the adhesive layer 52 (for example Figure 9A the thickness t2) is set to the length in the thickness direction of the sheet 51.

[0162] In addition, it is preferable that the three-dimensional decoration portion 54 (the portion where the decorative layer 53 and the adhesive layer 52 overlap) has portions with different thicknesses. For example, in Figure 9A the three-dimensional decoration portion 54, the central portion in a predetermined direction is recessed and the thickness becomes thinner. In Figure 10A the three-dimensional decoration portion 54, the thickness of the end portion in a predetermined direction is thinner than the thickness of the adjacent portion. In this way, it is easier to visually recognize the three-dimensional decoration portion 54 three-dimensionally, and it is easier for the user to have the impression that the sanitary napkin 1 is also three-dimensionally deformed and fitted.

[0163] In addition, it is preferable that, as Figure 9A , Figure 10A and Figure 10B shown, in the three-dimensional decoration portion 54, the thickness of the end portion 54E in a predetermined direction is smaller than the thickness of the portion 54I adjacent to the end portion 54E and closer to the inside in the predetermined direction. In this way, the three-dimensional decoration portion 54 bulges from the end portion 54E toward the portion 54I on the inside in the predetermined direction and is visually recognized, and it is easier to visually recognize the three-dimensional decoration portion 54 three-dimensionally.

[0164] In addition, as Figure 9A and Figure 10BAs shown, in the three-dimensional decorative portion 54, it is preferable that the central portion in a predetermined direction (on the side of the sheet 51 in the thickness direction) is recessed. In this way, the surface of the three-dimensional decorative portion 54 becomes an uneven shape, and it is easier to visually recognize the three-dimensional decorative portion 54 three-dimensionally. However, it is not limited to the above structure, and it may be, as Figure 10A shown, the thickness of the portion of the three-dimensional decorative portion 54 other than the end portions in the predetermined direction is constant, or it may be that the central portion in the predetermined direction of the three-dimensional decorative portion 54 bulges convexly and has a larger thickness.

[0165] So far, the relationships between the thicknesses and lengths of the respective parts have been described, and the above comparisons of thickness and length can be carried out by known methods. For example, comparison can be made by visually observing the target part, or comparison can be made based on an image obtained by magnifying the target part using an optical microscope and taking a picture. In addition, comparison can also be made according to a cross-sectional image obtained by cutting the target part.

[0166] In addition, it may be that the decorative sheet 50 not only has the three-dimensional decorative portion 54, but also has a flat printing layer 60 provided on the surface of the sheet 51, that is, an ordinary printing layer 60 formed by printing with ink. In this case, it is preferable that the three-dimensional decorative portion 54 (the adhesive layer 52 and the decorative layer 53) is provided on the local printing layer 60. For example, in Figure 8A and Figure 8B for the package 40, the three-dimensional decorative portion 54 in the pattern of petals is provided overlappingly on the printing layer 60 representing the color of the flower.

[0167] In this way, the local decoration presented by the printing layer 60 bulges and is visually recognized, and the user can further appreciate the decoration. In addition, when the local part of the decoration is the three-dimensional decorative portion 54, compared with the case where all the decorations are the three-dimensional decorative portion 54, the three-dimensional decorative portion 54 is more likely to be conspicuous. Therefore, it is easy for the user to focus on the three-dimensional decorative portion 54 and is likely to have an impression that the sanitary napkin 1 is also three-dimensionally deformed. In addition, the printing layer 60 is covered by the three-dimensional decorative portion 54, so that the printing layer 60 becomes less likely to peel off. On the contrary, even if the three-dimensional decorative portion 54 peels off from the sheet 51, the printing layer 60 can still be visually recognized. Thereby, a reduction in the appearance quality of the decorative sheet 50 can be suppressed, and a high-quality impression of the sanitary napkin 1 on the user can also be ensured.

[0168] ===Second Embodiment===

[0169] In the second embodiment, mainly the parts different from the first embodiment will be described. As in Figure 12As described above, in the individual package 30, the length obtained by subtracting the maximum lateral length W2 of the internal sanitary napkin 1 from the maximum lateral length W1 is defined as the "first length" (= W1 - W2). Further, for each of the plurality of individual packages 30 accommodated in the second package 402 having the non - existent region RN, the first length is obtained, and the difference between the maximum value and the minimum value of the first length is defined as the "first deviation amount" (= Max (W1 - W2) - Min (W1 - W2)). In the second package 402 included in the package group 100 of the second embodiment, the diameter D1 ( Figure 11B ) of the circumscribed circle 81 circumscribing the non - existent region RN is equal to or greater than the first deviation amount.

[0170] Therefore, compared with the case where the diameter D1 of the circumscribed circle 81 of the non - existent region RN is smaller than the first deviation amount, it is easier for the user to recognize the non - existent region RN. In addition, the unevenness formed by the non - existent region RN and the adjacent three - dimensional decorative portion 54 becomes distinct, and it is easier to visually recognize the three - dimensional decorative portion 54 three - dimensionally. Further, in the non - existent region RN, as Figure 9B shown, the adhesive layer 52 is exposed, or the sheet 51 is exposed, or the flat printing layer 60 printed on the sheet 51 is exposed. Since the length of the non - existent region RN is long, the user can also appreciate the design of the portions with different textures visually recognized between the decorative layers 53. In particular, in the ultraviolet - curable adhesive forming the adhesive layer 52, wrinkles are generated due to curing, and a pattern like a ripple is exposed, and the user can appreciate this pattern.

[0171] Further, as Figure 12 shown, in the individual package 30, the length from the opening end 30O to the longitudinal direction of the internal sanitary napkin 1 at the lateral center position CL is defined as the "second length L2". Further, for each of the plurality of individual packages 30 accommodated in the second package 402, the second length L2 is obtained respectively, and the difference between the maximum value and the minimum value of the second length L2 is defined as the "second deviation amount" (= Max (L2) - Min (L2)). In the second package 402 included in the package group 100 of the second embodiment, the diameter D1 of the circumscribed circle 81 circumscribing the non - existent region RN is equal to or greater than the second deviation amount.

[0172] In this case, it is also easy for the user to recognize the non - existent region RN. In addition, the unevenness formed by the non - existent region RN and the adjacent three - dimensional decorative portion 54 becomes distinct, and it is easier to visually recognize the three - dimensional decorative portion 54 three - dimensionally. Further, the user can appreciate the design of the portions with different textures (such as the ripple pattern formed by the curing of the adhesive layer 52) visually recognized between the decorative layers 53.

[0173] In addition, in the package group 100 of the second embodiment, the area of the non-existent region RN of the second package 402 is equal to or greater than the minimum value of the area a36 of the welding portion 36 provided in a certain independent package 30 of the second package 402.

[0174] In this case, it is also easy for the user to recognize the non-existent region RN. In addition, the unevenness formed by the non-existent region RN and the three-dimensional decorative portion 54 adjacent thereto becomes clear, and it is easier to visually recognize the three-dimensional decorative portion 54 three-dimensionally. In addition, the user can appreciate the design of the portions with different textures visually recognized from between the decorative layers 53 (such as the corrugated pattern formed by the curing of the adhesive layer 52).

[0175] === Manufacturing method of the decorative sheet 50 ===

[0176] Figure 18 This is a diagram for explaining the manufacturing method of the decorative sheet 50. The aforementioned decorative sheet 50 can be manufactured using Figure 18 the manufacturing apparatus 70 illustrated. The manufacturing apparatus 70 includes a conveying mechanism 71, an ink ejection device 72, an adhesive ejection device 73, a first irradiation device 74, a decorative layer conveying mechanism 75, and a second irradiation device 76.

[0177] The conveying mechanism 71 is a mechanism for conveying the continuous body 51c of the sheet 51 along the conveying direction. As the conveying mechanism 71, the conveying rollers shown in Figure 18 or a conveyor belt (not shown) can be exemplified. The ink ejection device 72 ejects ink onto the continuous body 51c of the sheet 51 conveyed by the conveying mechanism 71 along the conveying direction to form a flat normal printed layer 60.

[0178] On its downstream side, the adhesive ejection device 73 directly ejects the adhesive for forming the adhesive layer 52 onto the continuous body 51c of the sheet 51, or ejects the adhesive for forming the adhesive layer 52 onto the printed layer 60. In the present embodiment, a colorless and transparent ultraviolet curable adhesive is ejected. Thereafter, the first irradiation device 74 irradiates light (here, ultraviolet rays) that cures the adhesive layer 52, thereby curing the adhesive layer 52. However, the first irradiation device 74 irradiates ultraviolet rays to such an extent that the adhesive layer 52 is not completely cured. In this way, while fixing the shape of the adhesive layer 52, the adhesiveness is ensured. For this purpose, the intensity and irradiation time of the ultraviolet rays are adjusted.

[0179] In the present embodiment, an inkjet device is exemplified as the ink ejection device 72 and the adhesive ejection device 73. However, it is not limited thereto. For example, various printing methods (liquid coating methods) such as gravure printing and offset printing can also be used to form the printed layer 60 and the adhesive layer 52.

[0180] Thereafter, the decoration layer conveying mechanism 75 supplies the continuum 53c of the decoration layer 53 onto the adhesive layer 52. The decoration layer conveying mechanism 75 may include a device including a delivery roller (not shown) for delivering the continuum 53c of the decoration layer 53, a conveying roller 751, and a winding roller (not shown) for winding up the remaining portion of the continuum 53c of the decoration layer 53.

[0181] The length of the continuous body 53c of the decorative layer 53 in the direction perpendicular to the conveying direction is set to be greater than the length of the region where the adhesive layer 52 is formed. That is, it is set that the one or more adhesive layers 52 formed on the continuous body 51c of the sheet 51 are all covered by the continuous body 53c of the decorative layer 53. In addition, the continuous body 53c of the decorative layer 53 is supplied in a manner in contact with the surface of the adhesive layer 52. The adhesive layer 52 has adhesiveness, so the continuous body 53c of the decorative layer 53 is attached to the adhesive layer 52. During this time, the continuous body 53c of the decorative layer 53 and the adhesive layer 52 are also conveyed, and the decorative layer 53 attached to the adhesive layer 52 and the decorative layer 53 not in contact with the adhesive layer 52 are separated. The remaining portion of the continuous body 53c of the decorative layer 53 that is not attached to the adhesive layer 52 is wound on a winding roller and recovered.

[0182] Finally, the second irradiation device 76 irradiates light (ultraviolet rays in this case) for curing the adhesive layer 52, and completely cures the adhesive layer 52 via the decorative layer 53. Thus, the adhesive layer 52 and the decorative layer 53 are firmly bonded and integrated, and the three-dimensional decorative portion 54 is formed.

[0183] According to the above manufacturing method, the decorative layer 53 can be provided on the adhesive layer 52, and a three-dimensional decorative portion 54 can be formed in which the decorative layer 53 protrudes from the surface of the sheet 51 in the thickness direction of the sheet 51. In addition, when manufacturing the second package 402 and the third package 403, it is preferable to make the part where the non-existence area RN is formed different from that when manufacturing the first package 401. For example, it is preferable to make the state of the decorative layer 53 and the adhesive layer 52 different locally, or to make the curing state of the adhesive layer 52 different. However, the above manufacturing method is an example, and the manufacturing method of the decorative sheet 50 is not particularly limited.

[0184] The above embodiments are for easy understanding of the present invention and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
