Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of collection of absorbent article package. BACKGROUND

[0002] In patent document 1, a decoration sheet in which a mark layer (letters, figures, etc.) formed of a foil having a metal component is formed on a material sheet is manufactured. Specifically, it is a manufacturing method in which a transfer film having a foil and a material sheet are overlapped and conveyed between a pattern roller and a support roller, and the foil corresponding to the pattern of the outer peripheral surface of the pattern roller is pressure-bonded to the material sheet, thereby forming a mark layer.

[0003] PRIOR ART DOCUMENTS

[0004] PATENT DOCUMENTS

[0005] Patent document 1: Japanese Patent Application Publication No. 2022-12041 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] In the decoration sheet of patent document 1, the mark layer is formed by pressure-bonding the foil. Therefore, the mark layer becomes a concave shape with respect to the surroundings, and is smooth. Thus, if the collection of absorbent article packages is formed using the decoration sheet of patent document 1, the user easily has an impression that the absorbent article is also a flat product like the mark layer, and there is a possibility that the user worries whether the absorbent article is deformed three-dimensionally to fit 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 and stored by the user in a bathroom or the like. In the decoration sheet of patent document 1, the foil is pressure-bonded using the pattern roller, and thus the mark layer is easily formed to be the same. However, when the user visually recognizes a plurality of packages, monotony is easily felt. Therefore, there is a possibility that not only the degree of interest in the usual ink-based printing is reduced, but also the degree of interest in the decoration using the foil is reduced.

[0009] The utility model is completed in view of the above-mentioned problems, and aims to: in the collection of absorbent article packages using a decorative layer with a relatively thin thickness, give the user an impression that the absorbed absorbent article is a product that is easily deformed three-dimensionally to fit, and further improve the degree of interest in decoration.

DETAILED DESCRIPTION

[0063] According to the description and the drawings of the present specification, at least the following matters are clarified.

[0064] (way 1) An aggregate of absorbent article packages characterized by comprising: a plurality of absorbent article packages; and a bundle bundling the plurality of absorbent article packages, the absorbent article package having a storage body and a plurality of individual packages stored in the storage body, the storage body having a decorative sheet to which a decoration is applied, the decorative sheet having: a sheet; an adhesive layer provided on a 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 being provided at a position that can be visually recognized by a user, protruding in a thickness direction of the sheet from the surface of the sheet, the plurality of absorbent article packages having a first absorbent article package and a second absorbent article package, the first absorbent article package having, in the storage body, a first decorative layer presence region in which the decorative layer is present, the second absorbent article package having, in the storage body, a corresponding region corresponding to the first decorative layer presence region, the corresponding region having a second decorative layer presence region in which the decorative layer is present and a non-presence region in which the decorative layer is not present.

[0065] According to Mode 1, even a decorative layer having a maximum thickness that is thin can be projected in the thickness direction of the sheet by overlapping with the adhesive layer. The user who sees the decorative layer that is projected and becomes three-dimensional can be given the impression that the absorbent article also deforms three-dimensionally and fits. In addition, the first absorbent article package and the second absorbent article package produce a sense of unity while producing a difference in design depending on the presence or absence of the non-existing area. Thus, the user can recognize that the packages have the same absorbent article accommodated therein and appreciate the difference in design, and the fun of the three-dimensional decoration is further increased.

[0066] (Mode 2) On the basis of the collection of the absorbent article packages described in Mode 1, for each of the plurality of individual packages possessed by the second absorbent article package, a first length obtained by subtracting the maximum length of the absorbent article in the transverse direction of the individual package from the maximum length of the individual package in the transverse direction of the opening end is found, and the difference between the maximum value of the first length and the minimum value of the first length is set as a first deviation amount, and at this time, the diameter of the circumscribed circle circumscribing the non-existing area is smaller than the first deviation amount.

[0067] According to Mode 2, the first deviation amount of the individual package accommodated in the package is small to the extent that the user does not feel a sense of discord. The length of the non-existing area is smaller than the first deviation amount, so the user does not easily feel a sense of discord about the presence or absence of the non-existing area, and can appreciate the small difference in design of the absorbent article package.

[0068] (Mode 3) On the basis of the collection of the absorbent article packages described in Mode 1 or 2, 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 possessed by the second absorbent article package, a second length of the length of the longitudinal direction of the absorbent article from the opening end to the central position of the transverse direction is found, and the difference between the maximum value of the second length and the minimum value of the second length is set as a second deviation amount, and at this time, the diameter of the circumscribed circle circumscribing the non-existing area is smaller than the second deviation amount.

[0069] According to Mode 3, the second deviation amount of the individual package accommodated in the package is small to the extent that the user does not feel a sense of discord. The length of the non-existing area is smaller than the second deviation amount, so the user does not easily feel a sense of discord about the presence or absence of the non-existing area, and can appreciate the small difference in design of the absorbent article package.

[0070] (Mode 4)

[0071] On the basis of the collection of the absorbent article packages described in Mode 1, the individual package has a wrapping sheet, at both end portions of the individual package in the lateral direction along the opening end, the folded wrapping sheets are joined to each other by a plurality of fusion portions, and the area ratio of the non-existing region is smaller than the minimum value of the area of the fusion portion provided in the individual package of the second absorbent article package.

[0072] According to Mode 4, the user is less likely to feel a sense of discordance about the presence or absence of the non-existing region, and can appreciate small differences in the design of the absorbent article package.

[0073] (Mode 5) On the basis of the collection of the absorbent article packages described in Mode 1 or 4, for each of the plurality of individual packages possessed by the second absorbent article package, a first length obtained by subtracting the maximum length of the lateral direction of the inner absorbent article from the maximum length of the lateral direction of the individual package along the opening end is found, the difference between the maximum value of the first length and the minimum value of the first length is set as a first deviation amount, and at this time, the diameter of a circumscribed circle circumscribing the non-existing region is equal to or greater than the first deviation amount.

[0074] According to Mode 5, the user is likely to recognize the non-existing region, and can appreciate differences in the design of the absorbent article package. In addition, it is also possible to appreciate the design of a portion (for example, an adhesive layer) that is visually recognized as having a different texture from the decorative layer.

[0075] (Mode 6) On the basis of the collection of the absorbent article packages described in Mode 1 or 5, 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 possessed by the second absorbent article package, a second length of the longitudinal direction from the opening end to the inner absorbent article at the central position of the lateral direction is found, the difference between the maximum value of the second length and the minimum value of the second length is set as a second deviation amount, and at this time, the diameter of a circumscribed circle circumscribing the non-existing region is equal to or greater than the second deviation amount.

[0076] According to Mode 6, the user is likely to recognize the non-existing region, and can appreciate differences in the design of the absorbent article package. In addition, it is also possible to appreciate the design of a portion (for example, an adhesive layer) that is visually recognized as having a different texture from the decorative layer.

[0077] (way 7) On the basis of the collection of the absorbent article packages described in ways 1, 5, and 6, the individual package has a wrapping sheet, at both end portions of the individual package in the lateral direction along the opening end, the folded wrapping sheets are joined to each other by a plurality of fusion portions, and the area of the non-existing region is equal to or greater than the minimum value of the areas of the fusion portions provided in the certain individual package of the second absorbent article package.

[0078] According to way 7, the user easily recognizes the non-existing region and can appreciate the difference in the design of the absorbent article package. In addition, the design of the portion (e.g., the adhesive layer) having a different texture visually recognized between the decorative layers can also be appreciated.

[0079] (way 8) On the basis of the collection of the absorbent article packages described in ways 2 to 4, the individual package has a wrapping sheet, at both end portions of the individual package in the lateral direction, the folded wrapping sheets are joined to each other by a plurality of fusion portions, in the certain individual package of the second absorbent article package, the maximum value and the minimum value of the intervals of the fusion portions adjacent to each other in the lateral direction are found, the difference between the maximum value and the minimum value of the intervals is set as a third deviation amount, and at this time, the diameter of the circumscribed circle circumscribing the non-existing region is greater than the third deviation amount.

[0080] According to way 8, the third deviation amount of the fusion portions having a pattern of a concave-convex shape on the surface is small to the extent that the user does not notice. Therefore, by making the length of the non-existing region greater than the third deviation amount, the user can recognize the non-existing region and can appreciate the small difference in the design of the absorbent article package.

[0081] (way 9) On the basis of the collection of the absorbent article packages described in any one of ways 1 to 8, the storage body has a stacking direction in which the plurality of individual packages are stacked in the thickness direction thereof, in the second absorbent article package, the non-existing region is located on a face of the storage body orthogonal to the stacking direction, the individual package has an article existing portion in which the absorbent article exists and a non-article existing portion in which the absorbent article does not exist, and the non-existing region overlaps the article existing portion of at least one of the plurality of individual packages in the stacking direction.

[0082] According to way 9, the article existing portion has a thickness compared to the non-article existing portion, and in the portion of the storage body where the article existing portion is located, the sheet is stretched. The non-existing region located at this portion protrudes outward and is easily recognized by the user.

[0101] == Mode for Invention ==

[0102] Hereinafter, as the absorbent article, a sanitary napkin for physiological use is exemplified, and a collection of absorbent article packages each of which accommodates a plurality of absorbent articles is described. The absorbent article is not limited to the sanitary napkin for physiological use, and includes a disposable diaper of a panty type or a belt type, a sanitary pad, a panty-type sanitary napkin, a light incontinence pad, a urine absorption pad, a breast pad, an axillary sweat pad, a disposable diaper for pets, and other absorbent articles.

[0103] << Basic Structure of Sanitary Napkin 1 >>

[0104] Figure 1 is a plan view of the sanitary napkin 1 in a developed state as viewed from the skin side. Figure 2 is a schematic cross-sectional view of the sanitary napkin 1. The sanitary napkin 1 in the developed state has a length direction, a width direction, and a thickness direction that are orthogonal to each other. In the length direction, one side that abuts against the lower abdominal portion of the wearer is referred to as the "front side", and one side that abuts against the buttocks of the wearer is referred to as the "rear side". In addition, in the thickness direction of the sanitary napkin 1, one side that abuts against the skin of the wearer is referred to as the "skin side", and the opposite side thereof is referred to as the "non-skin side".

[0105] As Figure 2As shown, the sanitary napkin 1 has a surface sheet 2, an intermediate sheet 3, an absorbent body 10, a back sheet 4, a wing sheet 5, and a side sheet 6. Adjacent materials in the thickness direction are joined and fixed using an adhesive (not shown) such as a hot melt adhesive. The surface sheet 2 and the intermediate sheet 3 are liquid-permeable sheet members, and can be exemplified by nonwoven fabric or the like. The back sheet 4 is a liquid-impermeable sheet member, and can be exemplified by a resin film or the like. The side sheet 6 is folded back from the width direction end of the non-skin side of the absorbent body 10 to the inside in the width direction to the width direction end of the skin side of the surface sheet 2. The back sheet 4 and the wing sheet 5 project to the outside in the width direction with respect to the side sheet 6, and form a wing portion 1w in the central portion in the length direction of the sanitary napkin 1.

[0106] In addition, the surface sheet 2 that contacts the skin of the wearer can also be a sheet that uses cotton as a natural fiber (for example, a sheet member formed of 100% cotton, a mixed sheet of cotton and a hot air nonwoven fabric, or the like). In this way, irritation to the skin of the wearer can be reduced. In this case, as shown in the drawing described later, by providing a pattern that indicates cotton on the sanitary napkin 1, the individual packaging body 30, and the packaging body 40, the user can be shown the use of cotton. However, the surface sheet 2 can also not be a cotton sheet.

[0107] The absorbent body 10 is a member that absorbs and retains excretions inside. Figure 2 The absorbent body 10 of the sanitary napkin 1 has an absorbent core 11 and a core wrap sheet 12 that covers the absorbent core 11. The absorbent core 11 is formed by shaping pulp fibers that are liquid-absorbent fibers, cellulose-based absorbent fibers, or the like into a predetermined shape. The core wrap sheet 12 is a liquid-permeable sheet member, and can be exemplified by tissue paper or the like. However, the structure of the absorbent body 10 is not limited to the above-described structure, and can be, for example, an SAP sheet in which an SAP layer is attached to a hydrophilic sheet, an air-laid sheet in which liquid-absorbent fibers are formed into a sheet shape by an air-laying method, or the like. In addition, the sanitary napkin 1 has a compressed portion 20 in which the absorbent body 10 is compressed in the thickness direction from the skin side of the surface sheet 2.

[0108] The above describes the basic structure of the sanitary napkin 1, but the structure of the sanitary napkin is not limited to the above-described structure. For example, it can be a sanitary napkin or the like that does not have a wing portion 1w.

[0109] <<Individual packaging body 30 of sanitary napkin>>

[0110] Figure 3 is a plan view of the individual packaging body 30 of the sanitary napkin as viewed from the expanded state of the sanitary napkin from the non-skin side. Figure 4 is a plan view of the individual packaging body 30 of the sanitary napkin as viewed from the expanded state of the sanitary napkin from the skin side. Figure 5 is a plan view of the individual packaging body 30 of the sanitary napkin.

[0111] The individual packaging unit 30 (hereinafter also referred to as "individual packaging unit 30") of the sanitary napkin 1 is formed by independently packaging the sanitary napkin 1 with a packaging sheet 31, and includes the sanitary napkin 1, the packaging sheet 31, the fixing strap 32, and the release tabs 33 and 34. The packaging sheet 31 is a rectangular sheet component, and examples include resin film, non-woven fabric, paper, and sheets formed by laminating 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 of the packaging sheet 31, which is the short side, corresponds to the width direction of the sanitary napkin 1. The fixing strap 32 is provided at the end of the packaging sheet 31 in the length direction.

[0112] like Figure 3 As shown, multiple adhesive portions 8 and 9 coated with adhesive or the like are provided on the non-skin side of the sanitary napkin 1 (i.e., the non-skin side of the backing 4). Multiple rectangular adhesive portions 8 extending along the length direction are arranged in the width direction of the main body of the sanitary napkin 1. These adhesive portions 8 of the main body are used to fix the main body of the sanitary napkin 1 to the inner side of the wearer's underwear. Additionally, multiple rectangular adhesive portions 9 extending along the length direction are also arranged in the width direction of the wing portion 1w. When the sanitary napkin 1 is worn, the wing portion 1w is bent and fixed to the outer side of the underwear using the adhesive portions 9. Furthermore, the shape, number, and arrangement of the adhesive portions 8 and 9 are not limited to... Figure 3 The example is shown.

[0113] In the individual packaging 30, the non-skin side of the sanitary napkin 1 is secured to the packaging sheet 31 via a release liner 33. The release liner 33 covers the adhesive portion 8 of the main body of the sanitary napkin 1, allowing the sanitary napkin 1 to be easily peeled off when the individual packaging 30 is opened. Additionally, as... Figure 4 As shown, the wing 1w is folded inward in the width direction on the skin side of the sanitary napkin 1. The adhesive portion 9 of the wing 1w is covered by the release tab 34. In addition, the sanitary napkin 1 can be directly and peelably fixed to the packaging sheet 31 without being secured to the packaging sheet 31 through the release tab 33.

[0114] Packaging sheet 31 and sanitary napkin 1 Figure 4 The state begins with folding at two folds F1 and F2 along the transverse direction. The two ends of the packaging sheet 31, folded together with the sanitary napkin 1, are joined together, as shown... Figure 5 The joint 35 is formed as shown. Examples of joint methods at the joint 35 include known methods such as heat sealing, ultrasonic sealing, adhesives, and combinations thereof. Additionally, a retaining strap 32 is provided across the opening end of the packaging sheet 31. The user holds the retaining strap 32 and unfolds the folds F1 and F2 to open the individual packaging unit 30.

[0115] The independent packaging body 30 of the sanitary napkin has been described above, but the structure of the independent packaging body 30 is not limited to the above-described structure. For example, the number of the folded portions F1, F2 of the packaging sheet 31 is not limited to two, but can be one or more than three. Also, the packaging sheet 31 and the sanitary napkin 1 can be folded at the folded portions F1, F2 along the lateral direction as well as at the folded portions along the longitudinal direction. Also, the packaging sheet 31 and the sanitary napkin 1 can be folded independently. That is, the packaging sheet 31 can be folded with the sanitary napkin 1 preliminarily folded.

[0116] < sanitary napkin packaging body 40 >

[0117] Figure 6A is a perspective view of a sanitary napkin packaging body 40, Figure 6B is a view showing a state in which the housing body 41 is opened. The sanitary napkin packaging body 40 (absorbent article packaging body, hereinafter also referred to as "packaging body 40") has a housing body 41 and a plurality of independent packaging bodies 30 of sanitary napkins housed in the housing body 41.

[0118] Figure 6A The illustrated housing body 41 has an upper-lower direction, a left-right direction, and a front-rear direction, and has a main body portion 42 of a rectangular parallelepiped shape and a sealing member 43. The sealing member 43 is provided to the back surface 41B of the packaging body 40 (housing body 41). In detail, the sealing member 43 is provided to the upper portion of the rear side of the housing body 41. A pinch portion 431 is provided to the central portion in the left-right direction of the sealing member 43. In addition, a cut line 44 (for example, a tearable line) is formed at the 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, whereby as shown in Figure 6B the main body portion 42 is opened at the portion adhered to the sealing member 43 along the cut line 44, and an opening portion 45 which becomes an exit for the sanitary napkin 1 is formed.

[0119] In addition, Figure 6A The shape and structure of the illustrated housing body 41 are an example, and are not limited thereto. For example, the housing body can be a rectangular parallelepiped shape without the sealing member 43, a self-standing bag type, a flat bag, or the like.

[0120] < collection 100 of absorbent article packaging bodies >

[0121] Figure 7 is a schematic perspective view of a collection 100 of absorbent article packaging bodies.

[0122] The collection 100 of packaging bodies of absorbent articles has a plurality of packaging bodies 40 and a bundling member 101 which bundles the plurality of packaging bodies 40. As the bundling member 101, a corrugated box is illustrated here, but is not limited thereto. In Figure 7In the present embodiment, the packages 40 are bundled by the bundle 101 in a state of being arranged in 4 rows by 8 columns, but the number of the packages 40 bundled by the bundle 101 is not particularly limited as long as it is plural. Figure 7 The corrugated box shown is in an opened state, but in fact, the aggregate of the absorbent article packages is shipped from a factory to a store or the like in a state of being closed in the corrugated box. In the following description, the aggregate of the absorbent article packages is also referred to as a package group 100.

[0123] == First Embodiment ==

[0124] 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.

[0125] The housing 41 (specifically, the main body portion 42) of the package 40 of the sanitary napkin of the present embodiment has the decorative sheet 50 to which a decoration is applied. As shown in Figure 9A , the decorative sheet 50 has a sheet 51, an adhesive layer 52 provided on a 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, a metal foil, a holographic foil, a pigment foil, or the like (details will be described later) can be exemplified.

[0126] The decorative layer 53 is provided at a portion that can be visually recognized by a user and protrudes in a thickness direction of the sheet 51 from a surface of the sheet 51. That is, the decorative layer 53 protrudes from the surface of the sheet 51 around by the adhesive layer 52 formed in a manner of rising 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 the adhesive layer 52 is also referred to as a "three-dimensional decoration portion 54". As a cross-sectional shape of the three-dimensional decoration portion 54, the shapes shown in Figure 9A , Figure 9B , Figure 10A and Figure 10B can be exemplified. As shown in Figure 9A , Figure 9B , Figure 10A , the portion (52E) of the adhesive layer 52 that does not overlap the decorative layer 53 is not included in the three-dimensional decoration portion 54.

[0127] In the present embodiment, the three-dimensional decoration portion 54 (adhesive layer 52 + decorative layer 53) is provided at an outer side of the housing 41 of the package 40 and protrudes to an outside of the housing 41. In Figure 8A and Figure 8BIn the present embodiment, a case where the three-dimensional decorative portion 54 is provided on the front face 41F of the housing 41 is exemplified, and the three-dimensional decorative portion 54 is represented by blackish filling. The outline of the flower and the pattern of the petals are exhibited by the three-dimensional decorative portion 54.

[0128] Thus, even in a case where the sheet 51 is decorated with a decorative layer 53 (metal foil, hologram foil, pigment foil, etc.) having a thickness of 10 μm or less, a three-dimensional decoration (three-dimensional decorative portion 54) can be formed by providing the decorative layer 53 on the adhesive layer 52. A user who visually recognizes the three-dimensional decorative portion 54 provided on the housing 41 of the package 40 is likely to receive an impression that the product is three-dimensional. Therefore, the user is also likely to have an impression that the sanitary napkin 1 housed in the housing 41 is a product that is three-dimensionally deformed to conform to the body and thus is less likely to leak.

[0129] The kind of decoration exhibited by the three-dimensional decorative portion 54 is not particularly limited, and can be exemplified by a character, a number, a symbol (e.g., a musical note symbol, a mark, etc.), a figure (e.g., a circle, a polygon, a heart, a star, etc.), a pattern (e.g., a picture representing a shape of an article, an animal, a plant, a person, etc.), a geometric pattern, a color (a portion having a predetermined color difference with respect to the color of the sheet 51), or a decoration combining the above decorations. Figure 8A and Figure 8B The three-dimensional decorative portion 54 shown in the drawing is an example, and the shape, number, size, and arrangement of the three-dimensional decorative portion 54 are not particularly limited.

[0130] The adhesive layer 52 is a layer formed of a raw material that is maintained in a state of being raised 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, a colorless and transparent ultraviolet-curable adhesive is exemplified. The adhesive layer 52 as the ultraviolet-curable adhesive is irradiated with ultraviolet rays, and the decorative layer 53 is bonded to the adhesive layer 52 by the adhesiveness of the adhesive layer 52 that is locally cured. However, the present embodiment is not limited thereto, and other photocurable adhesives and the like can be used, for example. The viscosity and the like of the adhesive layer 52 are preferably adjusted in such a manner that the adhesive layer 52 is less likely to penetrate into the sheet 51 and is raised on the sheet 51. In addition, as the sheet 51 constituting the decorative sheet 50, a resin film, a nonwoven fabric, paper, and a sheet formed by laminating and combining the above materials can be exemplified.

[0131] The thickness of the decorative layer 53 is a length in a direction orthogonal to the surface of the decorative layer 53 (e.g., a length in a direction orthogonal to the surface of the sheet 51 when the decorative layer 53 is provided on the sheet 51). Figure 9ARegarding the maximum thickness (less than 10 μm) of the decorative layer 53 (in this case, the housing 41), it can be confirmed using known methods. For example, the portion of the decorative piece 50 (in this case, the housing 41) where the three-dimensional decorative portion 54 is formed is identified, and multiple samples are formed by cutting this portion at any number of points. Then, the cut surface of each sample is magnified and photographed using an optical microscope (e.g., a VHX-900F manufactured by Keyence Corporation). For each photographed cut surface, the maximum thickness of the decorative layer 53 is measured. The maximum value of the maximum thickness of each sample is set as the maximum thickness of the decorative layer 53, and it is confirmed to be less than 10 μm.

[0132] Package assembly 100 ( Figure 7 The multiple packages 40 possess Figure 8A The first package 401 (first absorbent article package) shown and Figure 8B The second package 402 (second absorbent article package) is shown. The first package 401 has a "first decorative layer presence area R1" in the housing 41 where the decorative layer 53 exists. On the other hand, the second package 402 has a "corresponding area Rc" in the housing 41 that corresponds to the first decorative layer presence area R1.

[0133] Furthermore, the same position of the housing 41 of each package 40 is set as the "reference position O". For example, the lower end of the front surface 41F of the housing 41 with the three-dimensional decorative part 54 in the vertical direction and the left end in the horizontal direction are set as the reference position O. The "corresponding area Rc" is the area that has the same positional relationship with the reference point O of the second package 402 when the positional relationship of the decorative layer 53 of the housing 41 of the first package 401 with respect to the reference point O is applied to the housing 41 of the second package 402.

[0134] Furthermore, the corresponding region Rc of the second package 402 has a "second decorative layer presence region R2" where the decorative layer 53 is present, just like the first package 401, and a "non-present region RN" where the decorative layer 53 is not present. That is, in the first package 401 and the second package 402, the configuration of the decorative layer 53 is only locally different in terms of the non-present region RN.

[0135] Specifically, in the first package 401, when a decorative layer 53 exists in a region offset by a certain length from the reference point O (e.g., offset by a length X to the right and offset by a length Y to the upward), this region is the first decorative layer presence region R1. In the second package 402, when a decorative layer 53 exists in the region Rc, which is the corresponding region offset by the same length from the reference point O (e.g., offset by a length X to the right and offset by a length Y to the upward), this region is the second decorative layer presence region R2. When no decorative layer 53 exists, this region is the non-existent region RN.

[0136] Thus, it is preferable that the package set 100 include the first package 401 and the second package 402 that are different in the arrangement of the decorative layer 53. In this way, the design of the plurality of packages 40 included in the package set 100 is partially different, and monotony of the decoration can be prevented. Thus, when the user visually recognizes the first package 401 and the second package 402 in a store, a bathroom at home, or the like, the user can enjoy the difference in the design. Therefore, not only can the interestingness of the ordinary flat printing based on ink be further improved, but also the interestingness of the three-dimensional decoration using the thin decorative layer 53 can be further improved. In addition, the user can identify the first package 401 and the second package 402 depending on the presence or absence of the non-existing area RN. For example, the user can quickly identify the package 40 being used.

[0137] In addition, it is assumed that if the corresponding area Rc of the second package 402 does not have the second decorative layer existing area R2, the arrangement of the decorative layer 53 is greatly different. In this way, there is a possibility that the user doubts whether the same product is accommodated in the two packages. In contrast, the corresponding area Rc of the second package 402 of the present embodiment has the second decorative layer existing area R2. Thus, a sense of unity is generated between the first package 401 and the second package 402, and the user can easily identify the case where the same product is accommodated in the two packages (401, 402).

[0138] Figure 9A 、 Figure 10A and Figure 10B is a cross-sectional view of the three-dimensional decorative portion 54 that is not adjacent to the non-existing area RN. Figure 9B is a cross-sectional view of the three-dimensional decorative portion 54 that is adjacent to the non-existing area RN. In Figure 9B , the adhesive layer 52 is present in the non-existing area RN, and the decorative layer 52 and the adhesive layer 52 that are different in texture can be visually recognized on the surface of the three-dimensional decoration. Thus, the user receives different impressions in the three-dimensional decorative portion 54 adjacent to the non-existing area RN and the three-dimensional decorative portion 54 that is not adjacent to the non-existing area RN. For example, in the case where the decorative layer 53 having a metallic luster is used, the manner of reflection of light is different depending on the presence or absence of the non-existing area RN, and the impression changes. Therefore, the user can further enjoy the difference in the three-dimensional decoration. However, the structure is not limited to the above, and the adhesive layer 52 can not be present in the non-existing area RN.

[0139] In addition, the non-existing area RN is adjacent to the three-dimensional decorative portion 54, and thus a concave-convex is formed on the surface, and the three-dimensional decorative portion 54 is visually recognized more three-dimensionally. Therefore, the user can further receive an impression that the sanitary napkin 1 accommodated in the package 40 is a product that is easily deformed three-dimensionally and fits.

[0140] Alternatively, it could be, such as Figure 9A and Figure 10A As shown, the decorative layer 53 is absent at the outer edge of the adhesive layer 52. That is, the adhesive layer 52 may have a protrusion 52E extending in a predetermined direction relative to the decorative layer 53. The adhesive layer 52 may extend in both directions in the predetermined direction as shown, or it may extend only in one direction. The region in the adhesive layer 52 of the second package 402 where the decorative layer 53 is absent corresponds to the protrusion 52E or the non-existent region RN. That is, when the decorative layer 53 is present in the corresponding region of the first package 401, it corresponds to the non-existent region RN; when the decorative layer 53 is absent in the corresponding region of the first package 401, it corresponds to the protrusion 52E. Furthermore, the non-existent region RN may be entirely surrounded by the decorative layer 53, or a portion of the outer periphery of the non-existent region RN may be adjacent to the adhesive layer 52 (protrusion 52E).

[0141] Furthermore, when an external force is applied to the decorative piece 50 (in this case, the housing 41), the force is easily applied to the protrusion 52E, which serves as the end of the adhesive layer 52. However, the adhesive layer 52 is formed from an adhesive material and is elastic, so it easily deforms along with the piece 51. Therefore, it is possible to suppress the adhesive layer 52 from peeling off from the piece 51. In particular, the maximum thickness t1 of the protrusion 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 the protrusion 52 deforms more easily along with the piece 51. In addition, the decorative layer 53 is not located at the end where force is easily applied, thereby suppressing the peeling of the adhesive layer 52 and the decorative layer 53, and the cracking of the decorative layer 53. The user, visually recognizing the three-dimensional decorative part 54 that maintains quality, is likely to have the impression that the sanitary napkin 1 is also a high-quality product.

[0142] Furthermore, it is preferable that the length L1 of the protrusion 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 preventing the protrusion 52E from becoming unnecessarily longer, it is possible to prevent a decrease in the aesthetic appeal (such as metallic luster) produced by the decorative layer 53. However, this is not limited to the above situation; other possibilities may also exist, such as... Figure 10B As shown, the adhesive layer 52 does not have a protrusion 52E.

[0143] Further, it is preferable that 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, according to the three-dimensional decorative portion 54 formed of a metal foil or a holographic foil, a color having a metallic luster such as gold or silver is exhibited, and thus the three-dimensional decorative portion 54 is easily noticeable. Thus, a user who visually recognizes the storage body 41 of the package 40 is likely to pay attention to the three-dimensional decorative portion 54 that shines, and is likely to have an impression that the sanitary napkin 1 is also three-dimensionally deformed. Further, the user is also likely to receive an impression that the product is high-class through the three-dimensional decorative portion 54 having the metallic luster. Thus, the user is likely to have an impression that the sanitary napkin 1 stored in the storage body 41 is a product of high quality (e.g., less likely to leak, comfortable to wear, etc.), and is likely to use the sanitary napkin 1 with peace of mind. On the other hand, the three-dimensional decorative portion 54 formed of a pigment foil becomes a matte decoration that is matting, and is likely to give the user an impression that the product is one that has a stable sense of security. Further, 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 sanitary napkin 1 that is stored.

[0144] As the metal foil, a metal foil obtained by beating a metal to make the metal thin and flat, a thin and flat sheet containing a metal (a coated film of a metal powder pigment, a metal vapor deposition film), and a sheet obtained by laminating the above member on a synthetic resin layer can be exemplified. As the metal contained in the metal foil, gold, silver, copper, tin, brass, aluminum, and the like can be exemplified.

[0145] The holographic foil refers to a thin and flat sheet having a property of reflecting incident light as a color using a prism effect. By providing a fine concave-convex pattern on the surface, a person who sees the reflected light is visually recognized a specific pattern.

[0146] As the pigment foil, a sheet obtained by laminating a coated film of a pigment on a synthetic resin layer can be exemplified. The color of the pigment can be exemplified as red, blue, yellow, black, white, and the like, and is not particularly limited. Further, the decorative layer 53 can be a foil material other than the metal foil, the holographic foil, and the pigment foil.

[0147] Figure 11A is an enlarged view of a portion of the first package 401, Figure 11B is an enlarged view of a portion of the second package 402. Figure 12 is an explanatory view of the amount of deviation of the individual package 30. Figure 13A-C is an explanatory view of the folding method of the panty-type sanitary napkin 80. Figure 14 is a plan view of the individual package 30 of the panty-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.

[0148] As Figure 12As shown in FIG. 1, in the individual package 30, a length obtained by subtracting a maximum length W2 in the transverse direction of the sanitary napkin 1 inside from a maximum length Wl in the transverse direction is set as a "first length" (= Wl - W2). Also, the first length is found for each of the individual packages 30 among a plurality of individual packages 30 (10 individual packages 30 in this case) housed in the second package 402 provided with the non-existing area RN. Among the first lengths of the plurality of individual packages 30, a difference between a maximum value of the first lengths and a minimum value of the first lengths is set as a "first deviation amount" (= Max (Wl - W2) - Min (Wl - W2)). At this time, it is preferable that a diameter Dl of a circumscribed circle 81 circumscribing the non-existing area RN (refer to FIG. 1) be smaller than the first deviation amount. Figure 11B ) than the first deviation amount.

[0149] The first length corresponds to a margin in the transverse direction of the wrapping sheet 31 of the individual package 30. In the plurality of individual packages 30 housed in the package 40, the margin of the wrapping sheet 31 is uneven due to manufacturing errors, thereby generating the first deviation amount. However, the deviation is small and can be suppressed to a degree that a user does not feel incongruity that the plurality of individual packages 30 are the same product. Therefore, by making the length of the non-existing area RN smaller than the first deviation amount, the user does not easily feel incongruity with the non-existing area RN. Thus, the user can enjoy a small difference in design while feeling unity from the first package 401 and the second package 402. In addition, by moderately suppressing the length of the non-existing area RN, an area of the decorative layer 53 can be ensured. Thus, a case where the aesthetic property (metallic luster, etc.) generated by the decorative layer 53 is reduced can be prevented.

[0150] In the present embodiment, as the absorbent article, the sanitary napkin 1 of the type attached to an undergarment is exemplified, but the absorbent article can be a panty-type sanitary napkin 80. At the time of packaging, portions of the panty-type sanitary napkin 80 on both outer sides in the lateral direction than the absorbent main body 81 are mostly folded at the folding portions Fl (refer to FIG. 1) after being folded in the lateral direction (refer to FIG. 1), and then folded in the vertical direction (refer to FIG. 1). Figure 13A Figure 13B In the present embodiment, as the absorbent article, the sanitary napkin 1 of the type attached to an undergarment is exemplified, but the absorbent article can be a panty-type sanitary napkin 80. At the time of packaging, portions of the panty-type sanitary napkin 80 on both outer sides in the lateral direction than the absorbent main body 81 are mostly folded at the folding portions Fl (refer to FIG. 1) after being folded in the lateral direction (refer to FIG. 1), and then folded in the vertical direction (refer to FIG. 1). Figure 14

[0151] In the above-described individual package 30 of the panty-type sanitary napkin 80, also, a length obtained by subtracting a maximum length W2 in the transverse direction of the panty-type sanitary napkin 80 inside from a maximum length Wl in the transverse direction is set as a "first length" (= Wl - W2). In addition, the above-described folding manner of the panty-type sanitary napkin 80 and the manner of packaging are one example and are not limited thereto.

[0152] In addition, the size of the non-existing area RN is more preferable as follows. As shown in FIG. 1, the non-existing area RN is preferably a circular shape.​​Figure 12 In the individual package 30, the length L2 in the longitudinal direction of the sanitary napkin 1 from the opening end 30O (the end of the wrapping sheet 31) to the central position CL in the lateral direction is set to "the first length Ll". The sanitary napkin 1 from the opening end 30O is the end la of the sanitary napkin 1 located on the opening end 30O side in the thickness direction of the individual package 30, that is, the end la of the sanitary napkin 1 folded at the folding portion Fl. In the first length Ll of each of the plurality of individual packages 30 housed in the first package 401, the difference between the maximum value of the first length Ll and the minimum value of the first length Ll is set to "the first deviation amount" (= Max(Ll) - Min(Ll)). At this time, it is preferable that the diameter Dl of the circumscribed circle 81 circumscribing the non-existing region RN be smaller than the first deviation amount.

[0153] The first length Ll corresponds to the margin in the longitudinal direction of the wrapping sheet 31 from the opening end 30O of the individual package 30 to the sanitary napkin 1. In the plurality of individual packages 30 housed in the first package 401, the margin of the wrapping sheet 31 is uneven due to manufacturing errors, thereby generating the first deviation amount. However, the deviation is small and can be suppressed to a degree that the user does not feel incongruity that the plurality of individual packages 30 are the same product. Therefore, by making the length of the non-existing region RN smaller than the first deviation amount, the user is less likely to feel incongruity with the non-existing region RN. Thus, the user can enjoy the small difference in design while feeling the unity from the first package 401 and the second package 402. In addition, it is possible to secure the area of the decorative layer 53 and prevent the decrease in aesthetics due to the decorative layer 53.

[0154] At both ends (the joint portions 35) of the individual package 30 in the lateral direction along the opening end 30O, the folded wrapping sheets 31 are joined to each other by a plurality of fusion portions 36. It is preferable that the area of the non-existing region RN be smaller than the minimum value among the areas a36 of the plurality of fusion portions 36 provided in a certain individual package 30 possessed by the second package 402. The certain individual package 30 is any one of the plurality of individual packages 30 possessed by the second package 402.

[0155] The area a36 of the welded portion 36 is large enough for the user to perceive, but since the sanitary napkin 1 occupies most of the individual packaging 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, the user is less likely to feel a sense of disharmony with the non-existent region RN. As a result, the user can appreciate the subtle differences in design while experiencing a sense of unity between the first packaging 401 and the second packaging 402. In addition, the area of ​​the decorative layer 53 can be secured to prevent a decrease in aesthetic appeal caused by the decorative layer 53. The area of ​​each region can be calculated using common image analysis software and area calculation software.

[0156] Furthermore, within a single package 30 of the second package 402, the maximum and minimum values ​​of the spacing W3 between adjacent welded portions 36 in the lateral direction are determined. For example... Figure 12 As shown, the interval W3 is the length between the side ends of adjacent welded portions 36 in the lateral direction. The difference between the maximum and minimum values ​​of the interval W3 among the plurality of welded portions 36 provided in a certain independent packaging body 30 is defined as the third deviation (=Max(W3)-Min(W3)). In this case, it is preferable that the diameter D1 of the circumcircle 81 circumscribed in the non-existent region RN is larger than the third deviation.

[0157] The welded portions 36 are formed using rollers or the like with raised and recessed patterns on their surfaces. Therefore, the deviation (third deviation) of the spacing W3 between the welded portions 36 is so small that the user will not notice it. Therefore, it is preferable that the length of the non-welded area RN is as small as described above, so that the user will not feel any disharmony, and is larger than the deviation of the spacing W3 between the welded portions 36 so that the user will notice it. In this way, the user can appreciate the subtle differences in the design of the first package 401 and the second package 402, and the difference in the impression of three-dimensional decoration created by the presence or absence of the non-existent area RN.

[0158] Figure 15 This is a cross-sectional schematic diagram of the storage unit 41. Figure 16 This is a top view of the individual package 30. (Example) Figure 15 As shown, the housing 41 has a plurality of individual packaging bodies 30 stacked along their thickness direction. In the packaging body 40 of this embodiment, the front-back direction of the housing 41 (the direction from the front side 41F through the back side 41B of the housing 41) is the stacking direction. In the second packaging body 402, when the non-existent region RN is located on the surface of the housing 41 orthogonal to the stacking direction (in this case, the front side 41F), the following is preferred.

[0159] like Figure 16As shown, the individual packages 30 have an article present portion R30 in which the sanitary napkins 1 are present and a non-article present portion R30n in which the sanitary napkins 1 are not present. The non-present region RN of the second package 402 preferably overlaps the article present portion R30 of at least one of the individual packages 30 in the stacking direction within the housing 41. It is preferable that the non-present region RN overlaps a plurality of the article present portions R30, and it is further preferable that the non-present region RN overlaps all of the article present portions R30.

[0160] The article present portion R30 of the individual package 30 has a greater thickness than the non-article present portion R30n. Therefore, in the central portion of the housing 41 in the left-right direction, the article present portions R30 are stacked and the thickness is increased, and the sheet 51 forming the housing 41 becomes in a stretched state. If the non-present region RN is located at this portion, the non-present region RN protrudes to the outside of the housing 41 and is easily recognized by the user. Thus, the user can appreciate the small difference in the design of the first package 401 and the second package 402, and the difference in the impression of the three-dimensional decoration produced by the presence or absence of the non-present region RN.

[0161] Further, the individual package 30 contains the sanitary napkin 1 folded in a Z-fold, and has a maximum stacking portion 11A in which the number of stacked absorbent cores 11 is the greatest. The sanitary napkin 1 of the present embodiment is folded at two folding portions F1, F2 as shown, and the central portion of the length direction of the absorbent core 11 overlaps the upper end portion of the absorbent core 11 folded at the folding portion F1 and the lower end portion of the absorbent core 11 folded at the folding portion F2, and is stacked in three layers. This portion stacked in three layers becomes the maximum stacking portion 11A. The maximum stacking portion 11A has the greatest thickness in the individual package 30. Therefore, the non-present region RN of the second package 402 preferably overlaps the maximum stacking portion 11A of all of the individual packages 30 in the stacking direction. Figure 4

[0162] Thus, the non-present region RN is located at a portion in which the thickness in the stacking direction of the housing 41 is the greatest and the sheet 51 forming the housing 41 is stretched to the greatest extent. Therefore, the non-present region RN further protrudes to the outside of the housing 41 and is easily recognized by the user.

[0163] However, the structure is not limited to the above. The individual package 30 has a minimum stacking portion 11B in which the number of stacked absorbent cores 11 is the smallest. In the sanitary napkin 1 of the present embodiment, the absorbent cores 11 do not overlap each other at the narrowed portion of the absorbent core 11 and become one layer, and become the minimum stacking portion 11B. The minimum stacking portion 11B has a smaller thickness than the maximum stacking portion 11A. It is also possible that the non-present region RN of the second package 402 overlaps the minimum stacking portion 11B of all of the individual packages 30 in the stacking direction.

[0164] ​Inside the housing 41, the sheet 51 extends less than the sheet 11A when the smallest stacked portion 11B of the absorbent core 11 is stacked, but extends more than the non-object-containing portion R30n. That is, the non-object-containing area RN is located where the sheet 51 extends moderately. In this case, the non-object-containing area RN is easily identifiable by the user, and the opening of the non-object-containing area RN due to outward bending caused by the extension of the sheet 51 can be suppressed. Therefore, the unevenness of the surface created by the decorative layer 53 and the non-object-containing area RN is easily maintained.

[0165] Alternatively, not limited to the above structure, the non-existent region RN of the second packaging body 402 may overlap with the non-item-existing portions R30n of all the individual packaging bodies 30 in the stacking direction. Inside the storage body 41, the non-item-existing portions R30n are stacked at the ends in the left and right directions, where the sanitary napkin 1 is not present, and the thickness is thinner compared to the central portion in the left and right directions. Thus, as Figure 15 As shown, the front surface 41F of the storage body 41 slopes downwards from the center towards the ends in the left-right direction. The non-existent area RN is located at the sloping part of the sheet 51, so that when the user visually identifies the front surface 41F of the storage body 41 along the stacking direction, the recess of the non-existent area RN is easily noticed. Thus, the user can appreciate the difference in the impression of three-dimensional decoration created by the presence or absence of the non-existent area RN.

[0166] In addition, such as Figure 8B As shown, the decorative layer 53 of the second package 402 has a first decorative layer portion 531 and a second decorative layer portion 532. The area of ​​the decorative layer 53 per unit area of ​​the sheet 51 is larger in the second decorative layer portion 532 than in the first decorative layer portion 531. Furthermore, the first decorative layer portion 531 and the second decorative layer portion 532 can be either portions of a continuous decorative layer 53 (e.g., decorative layers 53 forming the same pattern) or portions of a separate decorative layer 53 (e.g., decorative layers 53 forming individual patterns). Preferably, the non-existent region RN is located adjacent to the second decorative layer portion 532, which has a higher area ratio of decorative layer 53.

[0167] exist Figure 8B In the decorative layer 53, a non-existent region RN is provided in the area where the flower outline and petal pattern are continuous (second decorative layer portion 532). This area of ​​the decorative layer 53 has a larger area per unit area of ​​the decorative layer 53 compared to, for example, an area with only petal patterns (first decorative layer portion 531). Therefore, it is preferable that the non-existent region RN is located adjacent to the area of ​​the decorative layer 53 with the larger area. This way, even if the decorative layer 53 is absent in the non-existent region RN, the user is less likely to experience a sense of disharmony, and it also prevents the aesthetic appeal from being diminished by the decorative layer 53.

[0168] Figure 17A and Figure 17B is a front view of the package 40. In Figure 7 In the package set 100 shown in FIG. 10, the plurality of packages 40 bundled by the bundle 101 has a third package 403 (a third absorbent article package) in addition to the first package 401 and the second package 402. The housing 41 of the third package 403 also has, like the second package 402, a "further corresponding region Rc3" corresponding to the region of the first package 401 where the decorative layer 53 is present (the first decorative layer present region Rl). Also, the further corresponding region Rc3 has a third decorative layer present region R3 where the decorative layer 53 is present and a further non-present region RN3 where the decorative layer is not present. In a certain positional relationship with respect to the reference position O, the region where the decorative layer 53 is present in the first package 401 and also present in the third package 403 becomes the third decorative layer present region R3. In a certain positional relationship with respect to the reference position O, the region where the decorative layer 53 is present in the first package 401 but not present in the third package 403 becomes the further non-present region RN3. The third package 403 is unified with the first package 401 and the second package 402 by the third decorative layer present region R3.

[0169] Also, it is preferable that, as shown in Figure 17A and Figure 17B the relative position of the non-present region RN of the second package 402 with respect to the housing 41 is different from the relative position of the further non-present region RN3 of the third package 403 with respect to the housing 41. That is, it is preferable that the position of the non-present region RN with respect to the reference position O of the housing 41 is different from the position of the further non-present region RN3 with respect to the reference position O.

[0170] Thus, when the user visually recognizes the first package 401 to the third package 403, the arrangement of the decorative layer 53 is slightly different, and the user can enjoy the small difference in design. Also, in the third package 403, the three-dimensional decorative portion 54 adjacent to the further non-present region RN3 can be visually recognized more three-dimensionally, or the impression of the three-dimensional decoration can be changed depending on the presence or absence of the further non-present region RN3.

[0171] Also, it is preferable that the number of the non-present regions RN of the second package 402 is different from the number of the further non-present regions RN3 of the third package 403. For example, in Figure 17A and Figure 17BIn this case, the second package 402 has one non-existing region RN, and the third package 403 has three other non-existing regions RN3. In this way, a plurality of portions having different configurations of the decorative layer 53 exist, so that the user can easily recognize the difference in the design of the three-dimensional decoration, and can enjoy the small difference in the design.

[0172] Further, it is preferable that the area of the non-existing region RN of the second package 402 be different from the area of the other non-existing regions RN3 of the third package 403. For example, Figure 17B The illustrated third package 403 has other non-existing regions RN3 having an area larger than that of the non-existing region RN of the second package 402 and other non-existing regions RN3 having an area smaller than that of the non-existing region RN of the second package 402.

[0173] In this way, the user can easily recognize the difference in the design of the three-dimensional decoration, and can enjoy the small difference in the design. Further, the area of the non-existing region RN is different from the area of the other non-existing regions RN3, so that the impression of the three-dimensional decoration also changes, and the user can further enjoy the difference in the design.

[0174] Further, it is preferable that the weight per unit area of the adhesive layer 502 of the non-existing region RN of the second package 402 be different from the weight per unit area of the adhesive layer 52 of the other non-existing regions RN3 of the third package 403.

[0175] In this way, in the non-existing region RN and the other non-existing regions RN3, it is possible to make the recessed state of the adhesive layer 52 with respect to the adjacent decorative layer 53 different. Due to this, the impression of the three-dimensional decoration changes, and the user can further enjoy the difference in the design.

[0176] Further, the three-dimensional decorative portion 54 can be provided at an arbitrary position of the outer side surface of the housing 41 of the package 40. It is preferable that the three-dimensional decorative portion 54 be provided at the front surface (front surface) 41F of the housing 41 of the package 40. In this way, the three-dimensional decorative portion 54 is easily visually recognized by the user in a store or the like. Further, as the front surface of the housing 41, it is possible to exemplify the largest surface of a plurality of surfaces possessed by the housing 41, a surface on which a sales name (brand name), a storage number, or the like is largely written.

[0177] Furthermore, in the case of a package 40 having a sealing member 43, it is preferable that the sealing member 43 is provided on the back side 41B of the storage body 41 of the package 40, and that the three-dimensional decorative part 54 is not provided on the back side 41B of the storage body 41. When the sealing member 43 is opened, the user holds the back side 41B of the storage body 41, or the pulling force of the sealing member 43 is applied to the back side 41B of the storage body 41. Therefore, by not providing the three-dimensional decorative part 54 on the back side 41B (opening cover) of the storage body 41, it is possible to prevent the three-dimensional decorative part 54 from falling off and adhering to the user or the sanitary napkin 1 when opening the package.

[0178] Furthermore, it is preferable that the maximum thickness of the adhesive layer 52 is greater 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. This allows the thinner decorative layer 53 to protrude further from the surface of the surrounding sheet 51. Therefore, the three-dimensional decorative portion 54 becomes more three-dimensional, and the user can easily identify the presence of a three-dimensional decoration. In addition, as mentioned above, the thickness of the decorative layer 53 (e.g., Figure 9A 53t) is set as the length in a direction orthogonal to the surface of the decorative layer 53. The thickness of the adhesive layer 52 (e.g.) Figure 9A The thickness t2) is set as the length in the thickness direction of sheet 51.

[0179] Furthermore, it is preferable that the three-dimensional decorative portion 54 (the portion where the decorative layer 53 overlaps with the adhesive layer 52) has portions with varying thicknesses. For example, in Figure 9A In the three-dimensional decorative part 54, the central part in the predetermined direction is recessed and thinned. Figure 10A In the three-dimensional decorative part 54, the thickness of the end in the predetermined direction is thinner than the thickness of the adjacent part. In this way, the three-dimensional decorative part 54 is easier to visually identify in three dimensions, and the user is more likely to have the impression that the sanitary napkin 1 is also deformed in three dimensions and fits the body.

[0180] In addition, preferably, such as Figure 9A , Figure 10A as well as Figure 10B As shown, in the three-dimensional decorative portion 54, the thickness of the end portion 54E in the predetermined direction is smaller than the thickness of the portion 54I adjacent to the end portion 54E in the predetermined direction. In this way, the three-dimensional decorative portion 54 protrudes from the end portion 54E toward the portion 54I in the predetermined direction and is visually recognizable, making it easier to visually identify the three-dimensional decorative portion 54 in three dimensions.

[0181] In addition, such as Figure 9A and Figure 10BIn the three-dimensional decorative portion 54, the central portion in the predetermined direction (the sheet 51 side in the thickness direction) is preferably recessed. In this way, the surface of the three-dimensional decorative portion 54 becomes a concave-convex shape, and the three-dimensional decorative portion 54 is more easily visually recognized in three dimensions. However, the structure is not limited to the above-described structure, and, for example, the thickness of the three-dimensional decorative portion 54 can be constant except for the end portions in the predetermined direction, or the central portion in the predetermined direction of the three-dimensional decorative portion 54 can be convexly bulged and have a large thickness. Figure 10A As shown, the thickness of the three-dimensional decorative portion 54 is constant except for the end portions in the predetermined direction, and the central portion in the predetermined direction of the three-dimensional decorative portion 54 can be convexly bulged and have a large thickness.

[0182] Thus far, the relationship between the thickness and the length of each portion has been described, and the comparison of the above-described thickness and length can be performed by a publicly known method. For example, the comparison can be performed by visually observing the object portion, or the comparison can be performed based on an image captured by enlarging the object portion using an optical microscope. Alternatively, the comparison can be performed based on a cross-sectional image obtained by cutting the object portion.

[0183] Alternatively, the decorative sheet 50 can have not only the three-dimensional decorative portion 54 but also a flat printed layer 60 provided on the surface of the sheet 51, that is, a general printed layer 60 printed with ink. In this case, the three-dimensional decorative portion 54 (the adhesive layer 52 and the decorative layer 53) is preferably provided on the printed layer 60 in a partial region. For example, in the case of the package 40 of Figure 8A and Figure 8B the package 40, the three-dimensional decorative portion 54 of the petal pattern is overlaid on the printed layer 60 of the color representing the flower.

[0184] In this way, the partial protrusion of the decoration exhibited by the printed layer 60 is visually recognized, and the user can further enjoy the decoration. In addition, in the case where the partial decoration is the three-dimensional decorative portion 54, the three-dimensional decorative portion 54 is more easily noticeable than in the case where all of the decoration is the three-dimensional decorative portion 54. Thus, the user easily focuses on the three-dimensional decorative portion 54, and is easily impressed that the sanitary napkin 1 also has a three-dimensionally deformed appearance. In addition, the printed layer 60 is covered with the three-dimensional decorative portion 54, and thus the printed layer 60 becomes less likely to be peeled off. Conversely, even if the three-dimensional decorative portion 54 is peeled off from the sheet 51, the printed layer 60 is visually recognized. Thus, it is possible to suppress a decrease in the appearance quality of the decorative sheet 50 and to ensure a high-quality impression of the sanitary napkin 1 by the user.

[0185] === Second Embodiment ===

[0186] In the second embodiment, only the portions different from the first embodiment will be described. As in the Figure 12As explained, in the individual packaging 30, the length obtained by subtracting the maximum horizontal length W2 of the sanitary napkin 1 from the maximum horizontal length W1 is defined as the "first length" (=W1-W2). Furthermore, for each of the multiple individual packaging 30 housed in the second packaging 402 having a non-existent region RN, the first length is calculated, and the difference between the maximum and minimum values ​​of the first length is defined as the "first deviation" (=Max(W1-W2)-Min(W1-W2)). In the second packaging 402 of the packaging group 100 in the second embodiment, the diameter D1 of the circumscribed circle 81 circumscribed in the non-existent region RN is... Figure 11B () is above the first deviation amount.

[0187] Therefore, compared to the case where the diameter D1 of the circumcircle 81 of the non-existent region RN is smaller than the first deviation, the user can more easily identify the non-existent region RN. Furthermore, the unevenness formed by the non-existent region RN and the adjacent three-dimensional decorative part 54 becomes clearer, making it easier to visually identify the three-dimensional decorative part 54 in three dimensions. Additionally, in the non-existent region RN, such as... Figure 9B The adhesive layer 52 is exposed, or the sheet 51 is exposed, or the flat printed layer 60 printed on the sheet 51 is exposed. The non-existent area RN is longer, so that the user can also appreciate the design of the different textures that can be visually identified between the decorative layers 53. In particular, in the UV-curable adhesive that forms the adhesive layer 52, wrinkles and ripple-like patterns are exposed due to curing, which the user can appreciate.

[0188] In addition, such as Figure 12 As shown, in the individual packaging 30, the longitudinal length from the opening end 30O to the sanitary napkin 1 at the transverse central position CL is defined as the "second length L2". Furthermore, for each of the multiple individual packaging 30 housed in the second packaging 402, the second length L2 is calculated, and the difference between the maximum and minimum values ​​of the second length L2 is defined as the "second deviation" (=Max(L2)-Min(L2)). In the second packaging 402 of the packaging assembly 100 in the second embodiment, the diameter D1 of the circumscribed circle 81 circumscribed in the non-existent region RN is greater than or equal to the second deviation.

[0189] In this case, the user can easily identify the non-existent area RN. Furthermore, the unevenness formed by the non-existent area RN and the adjacent three-dimensional decorative part 54 becomes clearer, making it easier to visually identify the three-dimensional decorative part 54 in three dimensions. Additionally, the user can appreciate the design of the different textures visible between the decorative layers 53 (such as the wavy pattern formed by the curing of the adhesive layer 52).

[0190] Further, in the package group 100 of the second embodiment, the area of the non-existing region RN possessed by the second package 402 is equal to or greater than the minimum value of the area a36 of the fusion portion 36 provided in the individual package 30 possessed by the second package 402.

[0191] In this case, the user also easily recognizes the non-existing region RN. Further, the concave-convex formed by the non-existing region RN and the three-dimensional decorative portion 54 adjacent thereto becomes clear, and the three-dimensional decorative portion 54 is more easily visually recognized in three dimensions. Further, the user can enjoy the design of the portions of different textures visually recognized between the decorative layers 53 (the corrugation pattern formed by the curing of the adhesive layer 52, etc.).

[0192] == Manufacturing method of decorative sheet 50 ==

[0193] Figure 18 is a view for explaining the manufacturing method of the decorative sheet 50. The aforementioned decorative sheet 50 can be manufactured by the manufacturing apparatus 70 exemplified in Figure 18 . The manufacturing apparatus 70 has a conveyance mechanism 71, an ink ejection apparatus 72, an adhesive ejection apparatus 73, a first irradiation apparatus 74, a decorative layer conveyance mechanism 75, and a second irradiation apparatus 76.

[0194] The conveyance mechanism 71 is a mechanism for conveying the continuous body 51c of the sheet 51 in the conveyance direction. As the conveyance mechanism 71, the conveyance roll shown in Figure 18 , a conveyance belt, etc. not shown can be exemplified. The ink ejection apparatus 72 ejects ink to the continuous body 51c of the sheet 51 conveyed in the conveyance direction by the conveyance mechanism 71 to form the flat normal printed layer 60.

[0195] On the downstream side thereof, the adhesive ejection apparatus 73 directly ejects the adhesive forming the adhesive layer 52 to the continuous body 51c of the sheet 51 or to the printed layer 60. In the present embodiment, colorless transparent ultraviolet-curable adhesive is ejected. Thereafter, the first irradiation apparatus 74 irradiates light (ultraviolet rays in this case) that cures the adhesive layer 52, thereby curing the adhesive layer 52. However, the first irradiation apparatus 74 irradiates ultraviolet rays to the extent that the adhesive layer 52 is not completely cured. In this way, the shape of the adhesive layer 52 is fixed while adhesiveness is ensured. For this reason, the intensity of the ultraviolet rays and the irradiation time are adjusted.

[0196] In the present embodiment, as the ink ejection apparatus 72 and the adhesive ejection apparatus 73, an inkjet apparatus is exemplified. However, the present application is not limited thereto, and various printing methods (liquid coating methods) such as gravure printing, offset printing, etc. can be used to form the printed layer 60 and the adhesive layer 52.

[0197] Subsequently, the decorative layer conveying mechanism 75 feeds the continuous body 53c of the decorative layer 53 onto the adhesive layer 52. As the decorative layer conveying mechanism 75, a device having a non-illustrated feed roller that feeds the continuous body 53c of the decorative layer 53, a conveying roller 751, and a non-illustrated winding roller that winds the remaining portion of the continuous body 53c of the decorative layer 53 can be exemplified.

[0198] In a direction orthogonal to the conveying direction, the length of the continuous body 53c of the decorative layer 53 is set to be equal to or greater than the length of the region in which the adhesive layer 52 is formed. That is, the one or more adhesive layers 52 formed in the continuous body 51c of the sheet 51 are all covered with the continuous body 53c of the decorative layer 53. In addition, the continuous body 53c of the decorative layer 53 is fed so as to be in contact with the surface of the adhesive layer 52. The adhesive layer 52 has adhesiveness, and thus the continuous body 53c of the decorative layer 53 is attached to the adhesive layer 52. Meanwhile, the continuous body 53c of the decorative layer 53 and the adhesive layer 52 are conveyed, and the decorative layer 53 that is attached to the adhesive layer 52 and the decorative layer 53 that is 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 around the winding roller and is recovered.

[0199] Finally, the second irradiation device 76 irradiates light (in this case, ultraviolet rays) that causes the adhesive layer 52 to cure, and causes the adhesive layer 52 to be completely cured through the decorative layer 53. Thus, the adhesive layer 52 and the decorative layer 53 are firmly attached and integrated, and the three-dimensional decorative portion 54 is formed.

[0200] According to the manufacturing method described above, the decorative layer 53 can be provided on the adhesive layer 52, and the three-dimensional decorative portion 54 in which the decorative layer 53 protrudes from the surface of the sheet 51 in the thickness direction of the sheet 51 is formed. In addition, when manufacturing the second package 402 and the third package 403, it is more preferable to partially change the position at which the non-existing region RN is formed, compared to when manufacturing the first package 401. For example, it is more preferable to partially change the state of the decorative layer 53 and the adhesive layer 52, or to change the curing condition of the adhesive layer 52. However, the manufacturing method described above is an example, and the manufacturing method of the decorative sheet 50 is not particularly limited.

[0201] The above-described embodiments are used for easy understanding of the present application, and are not used for limiting explanation of the present application. The present application can be changed and improved without departing from the gist thereof, and the present application includes equivalents thereof, which is self-evident.
