Description

This invention relates to an absorbent article container in which perfumed absorbent articles are individually wrapped in a packaging sheet and the packages are contained within a container sheet.

There are known absorbent article packages in which absorbent articles having a fragrance are individually packaged in a packaging sheet (see, for example, Patent Documents 1 and 2). The packaging sheet of Patent Document 1 is configured to have a permeability of 25% or less according to the permeability test for menthyl lactate described in that document. The packaging sheet of Patent Document 2 is configured to have an oxygen transmission rate of 100 cc/ ^m2 /day/atm or less at 23°C. That is, the packages of Patent Documents 1 and 2 are configured to reduce the gas permeability of the packaging sheet and prevent the evaporation of the fragrance.

JP 2007-525245 A JP 2021-159410 A

According to the packages of Patent Documents 1 and 2, the evaporation of the fragrance before the package is opened can be suppressed. However, before the package is opened, for example, when a container that contains multiple packages is opened or when the package is carried, the fragrance is unlikely to evaporate outside the package, and the user may not notice the presence of the fragrance or may not be able to enjoy the fragrance before opening the package. Also, in order for the user to enjoy the fragrance before using the absorbent article, it is conceivable that the user may open part of the package. However, if part of the package is opened before use, the hygienic state of the absorbent article may not be maintained.

This invention was made in consideration of these problems, and aims to provide a container for absorbent articles that maintains the hygiene of the absorbent article before use and allows the user to apply a fragrance before opening the package.

In one embodiment, the absorbent article container contains a laminate in which absorbent article packages are stacked, in a container sheet. The absorbent article package individually packages absorbent articles containing a fragrance in a packaging sheet. When placed in a front view, the container has a vertical direction extending in the up-down direction, a horizontal direction perpendicular to the vertical direction, and a depth direction perpendicular to the vertical direction and the horizontal direction. When placed in the placed state, the horizontal length of the laminate is C, the depth length of the laminate is D, and the horizontal length of a storage space in the container that stores the laminate is F, the container satisfies ( ^C2 + ^D2 ) ^1/2 >F. The oxygen permeability of the container sheet is lower than that of the packaging sheet, and is 200cc/ ^m2 /day/atm or less at 23°C.

In another embodiment, the absorbent article container contains a laminate in which absorbent article packages are stacked, in a container sheet. The absorbent article package individually packages absorbent articles containing fragrances in a packaging sheet. When placed in a front view, the container has a vertical direction extending in the up-down direction, a horizontal direction perpendicular to the vertical direction, and a depth direction perpendicular to the vertical and horizontal directions. In the placed state, the difference between the horizontal length of the storage space in the container that contains the laminate and the horizontal length of the laminate is constant over the entire vertical area of the laminate. The oxygen permeability of the container sheet is lower than that of the packaging sheet, and is 200 cc/ ^m2 /day/atm or less at 23°C.

FIG. 1 is a perspective view of a container of an absorbent article according to an embodiment, as viewed from the front side. FIG. 2 is a cross-sectional view of a cross section extending in the lateral and depth directions of a container of an absorbent article according to an embodiment. FIG. 3 is a cross-sectional view of a cross section extending in the vertical direction and the depth direction of a container of an absorbent article according to an embodiment. FIG. 4 is a plan view of a package for absorbent articles.

(1) Overview of the embodiment At least the following points will become apparent from the description of this specification and the accompanying drawings.
The absorbent article container according to the first aspect contains a laminate in which absorbent article packages are stacked, in a container sheet. The absorbent article package contains absorbent articles having fragrance individually wrapped in a packaging sheet. The container, in a state in which the container is placed as viewed from the front, has a vertical direction extending in the up-down direction, a horizontal direction perpendicular to the vertical direction, and a depth direction perpendicular to the vertical direction and the horizontal direction. In the placed state, the horizontal length of the laminate is C, the depth length of the laminate is D, and the horizontal length of the storage space in the container that contains the laminate is F, so that (C ² +D ² ) ^1/2 >F is satisfied. The oxygen permeability of the container sheet is lower than that of the packaging sheet, and is 200 cc/m ² /day/atm or less at 23°C. The oxygen permeability of the container sheet has a predetermined oxygen permeability, i.e., it is airtight. Therefore, the fragrance can be suppressed from volatilizing from the container during storage of the absorbent article. In addition, since the oxygen permeability of the packaging sheet is higher than that of the storage sheet, the fragrance volatilizes through the packaging sheet, but is difficult to volatilize through the storage sheet. Therefore, when the container is opened and before the packaging is opened, a part of the fragrance volatilizes outside the packaging and is given to the user. The user can enjoy the fragrance component of the fragrance in a state in which the absorbent article is maintained in a hygienic state by the packaging. In addition, if the horizontal length of the storage space that stores the laminate in the container is longer than the diagonal length of the laminate, the volume of the storage space becomes too large compared to the volume of the laminate, and the fragrance volatilizes too much in the container, and there is a risk that the fragrance cannot be sufficiently given to the user when the absorbent article is used. However, since the volume of the storage space is not too large compared to the volume of the laminate, excessive volatilization of the fragrance in the container can be suppressed, and it is possible to store the absorbent article for a long period of time. Therefore, the fragrance can be given to the user before the packaging is opened while maintaining the hygienic state of the absorbent article before use.

The absorbent article container according to the second aspect contains a laminate in which absorbent article packages are stacked, in a container sheet. The absorbent article package contains absorbent articles having a fragrance individually wrapped in a packaging sheet. The container, in a state in which the container is placed in a front view, has a vertical direction extending in the up-down direction, a horizontal direction perpendicular to the vertical direction, and a depth direction perpendicular to the vertical direction and the horizontal direction. In the placed state, the difference between the horizontal length of the storage space in the container that contains the laminate and the horizontal length of the laminate is constant over the entire vertical area of the laminate. The oxygen permeability of the container sheet is lower than that of the packaging sheet, and is 200 cc/m ² /day/atm or less at 23° C. The oxygen permeability of the container sheet has a predetermined oxygen permeability, i.e., it has airtightness. Therefore, it is possible to suppress the fragrance from volatilizing from the container during storage of the absorbent article. In addition, since the oxygen permeability of the packaging sheet is higher than that of the storage sheet, the fragrance volatilizes through the packaging sheet, but is difficult to volatilize through the storage sheet. Therefore, when the storage body is opened and before the packaging body is opened, a part of the fragrance volatilizes outside the packaging body and is given to the user. The user can enjoy the fragrance component of the fragrance in a state where the absorbent article is kept hygienic by the packaging body. In addition, since the difference between the lateral length of the storage space that stores the laminate in the storage body and the lateral length of the laminate is constant, the volume of the storage space is not too large compared to the volume of the laminate, so that excessive volatilization of the fragrance in the storage body can be suppressed and it can be stored for a long period of time. Therefore, the fragrance can be given to the user before the packaging body is opened while maintaining the hygienic state of the absorbent article before use.

According to a preferred embodiment, the device according to embodiment 3 may have the following features in the device according to embodiment 1 or 2: The oxygen permeability of the storage sheet is 100 cc/ ^m2 /day/atm or less at 23° C. The oxygen permeability of the packaging sheet is higher than 200 cc/ ^m2 /day/atm at 23° C. According to this embodiment, since there is a large difference between the oxygen permeability of the packaging sheet and the oxygen permeability of the storage sheet, it is easy for the fragrance to volatilize through the packaging sheet but remain in the storage sheet.

According to a preferred embodiment, the device according to embodiment 4 may have the following features in the device according to any one of embodiments 1 to 3. The storage sheet includes a low-oxygen-permeable layer made of alumina-based vapor deposition or EVOH resin (ethylene-vinyl alcohol copolymer). The packaging sheet is a resin layer that does not include the low-oxygen-permeable layer. According to this embodiment, the difference between the oxygen permeability of the packaging sheet and the oxygen permeability of the storage sheet becomes large, and it becomes easier for the fragrance to volatilize through the packaging sheet but remain in the storage sheet.

According to a preferred embodiment, the device according to embodiment 5 may have the following features in the device according to any one of embodiments 1 to 4. The packaging body contains the absorbent article by joining the packaging sheet with a packaging joint. The container seals the packaging body by joining the container sheet with a container joint. At least a portion of the packaging joint is discontinuous. The container joint is continuous. According to this embodiment, it is possible to increase the sealing property of the container while decreasing the sealing property of the packaging body, and to volatilize the fragrance through the packaging body while retaining the fragrance within the container without volatilizing the fragrance through the container sheet.

According to a preferred embodiment, the device according to embodiment 6 may have the following features in the device according to any one of embodiments 1 to 5. The packaging body has a first direction and a second direction perpendicular to the thickness direction. The packaging joint has a first packaging joint that joins the packaging sheets at both ends in the first direction of the packaging body when the packaging sheet and the absorbent article are folded multiple times around a fold extending in the first direction, and a second packaging joint that stops the end of the packaging sheet in the second direction. One of the first packaging joint and the second packaging joint is provided continuously. The other of the first packaging joint and the second packaging joint is provided discontinuously. According to this embodiment, it is possible to volatilize the fragrance in the packaging body through the discontinuous packaging joint, while suppressing excessive volatilization of the fragrance through the continuous packaging joint.

According to a preferred embodiment, the device according to embodiment 7 may have the following features in the device according to any one of embodiments 1 to 6. The packaging body contains the absorbent article by joining the packaging sheet with a packaging joint. The container seals the packaging body by joining the container sheet with a container joint. The length in the orthogonal direction perpendicular to the extension direction of the packaging joint is shorter than the length in the orthogonal direction perpendicular to the extension direction of the container joint. According to this embodiment, it is possible to increase the sealing property of the container while decreasing the sealing property of the packaging body, and to volatilize the fragrance through the packaging body while retaining the fragrance within the container without volatilizing the fragrance through the container sheet.

According to a preferred embodiment, the device according to embodiment 8 may have the following features in the device according to any one of embodiments 1 to 7. The packaging body has a first direction and a second direction perpendicular to the thickness direction. The packaging joint has a pair of first packaging joints that join the packaging sheets arranged at both ends of the packaging body in the first direction when the packaging sheet and the absorbent article are folded multiple times around a fold extending in the first direction. In the extended state of the packaging body, the distance between the outer edges of the pair of first packaging joints in the first direction is longer than the length of the storage space of the container in the first direction. The distance between the inner edges of the pair of first packaging joints in the first direction is shorter than the length of the storage space of the container in the first direction. According to this embodiment, since the length between the outer edges of the first packaging joints in the first direction is longer than the length of the storage space of the container in the first direction, at least one of the pair of first packaging joints is folded inside the container. Therefore, by folding the packaging joint, it is possible to suppress the volatilization of the fragrance from the end of the packaging body in the first direction, and it is possible to store it suitably for a long period of time. In addition, because the length between the inner edges of the first packaging joint in the first direction is shorter than the length of the storage space of the container in the first direction, the packaging space of the packaging body sandwiched between the first packaging joint is less likely to be pressed by external forces inside the container, suppressing deformation of the absorbent article inside and suppressing the evaporation of fragrance due to deformation of the absorbent article due to external forces.

According to a preferred embodiment, the device according to embodiment 9 may have the following features in the device according to any one of embodiments 1 to 8. The fragrance includes a cooling or warming agent that acts on receptor-activated channels (TRPs) and has a vapor pressure of 0.01 mbar or less at 20°C. By using a fragrance that is a cooling or warming agent with low volatility, the user can enjoy the scent and feel the effect of a cooling or warming sensation.

According to a preferred embodiment, the device according to embodiment 10 may have the following features in the device according to any one of embodiments 1 to 9. The repulsive force in the thickness direction of the absorbent article is 0.0539 N ^cm2 or less. According to this embodiment, the repulsive force of the absorbent article is low, and the absorbent article is easily deformed when a force is applied from the outside of the package. Therefore, when the package is carried, for example, the absorbent article inside the package is deformed in a state where the package is alone, and the deformation causes the fragrance of the absorbent article to volatilize, and the fragrance component can be imparted to the user.

According to a preferred embodiment, the device according to embodiment 11 may have the following features in the device according to any one of embodiments 1 to 10. The value of the bending stiffness B of the storage sheet is 0.25 g·cm ² /cm or less. According to this embodiment, the bending stiffness of the storage sheet is relatively low, and it is easy to flexibly deform when an external force is applied. If the storage sheet is in a form that is difficult to flexibly deform, the storage sheet is easily torn by external pressure, and the internal scent components may escape, making it impossible to store for a long period of time. However, the storage sheet is flexibly deformed to suppress unintended breakage, and can be stored for a long period of time while retaining the fragrance.

(2) Configuration of the absorbent article container Hereinafter, the absorbent article container 1 according to the embodiment (hereinafter referred to as container 1) will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are given the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of the dimensions are different from the actual ones. Therefore, the specific dimensions should be determined with reference to the following description. In addition, the drawings may include parts with different dimensional relationships and ratios.

1 is a perspective view of the container 1. FIG. 2 is a cross-sectional view of the container 1 in the horizontal direction Y and the depth direction Z. FIG. 3 is a cross-sectional view of the container 1 in the vertical direction X and the depth direction Z. The container 1 contains a stack 50 in which absorbent article packages (hereinafter referred to as packages) 10 are stacked, by a storage sheet 2. FIG. 4 is a plan view of the absorbent article package 10. The container 1 has a storage space 7 in which the stack 50 is contained by folding the storage sheet 2 and joining the storage sheet 2 via a storage joint 5. The stack 50 is contained in the storage space 7. The stack 50 is formed by stacking the packages 10 in at least the thickness direction T of the absorbent article 20 (see FIG. 4). There are multiple packages 10 contained in the storage space 7. The laminate 50 may be an assembly in which the packaging bodies 10 are stacked in the thickness direction T, and the assembly may be arranged in the width direction W or the front-to-back direction L of the absorbent article 20. That is, the laminate 50 may have the packaging bodies 10 stacked in the thickness direction T and the width direction W, or may have the packaging bodies 10 stacked in the thickness direction T and the front-to-back direction L, or may have the packaging bodies 10 stacked only in the thickness direction T. In the laminate 50 of this embodiment, the packaging bodies 10 are stacked only in the thickness direction T.

The packaging body 10 individually packages the absorbent article 20 containing the fragrance with a packaging sheet 12. As shown in FIG. 4, the packaging sheet 12 may be folded together with the absorbent article 20 to individually package the absorbent article 20. Alternatively, the packaging sheet 12 may be formed in advance into a bag shape and configured to accommodate the absorbent article 20 in a folded state. Examples of the absorbent article 20 include disposable diapers, sanitary napkins, incontinence pads, and panty liners. The absorbent article 20 contains a fragrance and is configured to impart a fragrance component to the user at least during use. The fragrance may be attached to the absorbent article 20, and may be attached to any of the top sheet, back sheet, and absorbent core, or may be attached to an adhesive that bonds the members together.

The container 1 may have a vertical direction X extending in the up-down direction, a horizontal direction Y perpendicular to the vertical direction X, and a depth direction Z perpendicular to the vertical direction X and the horizontal direction Y in a placed state when viewed from the front. The placed state is a state in which the front 101 is selected from the design of the container 1 with the orientation of the characters 8 of the container 1 aligned in the up-down direction, and the container 1 is placed with the front side facing forward. FIG. 1 is a perspective view of the container 1 in a placed state from the front side. The design of the front side has a design for the user, and generally includes information such as the name of the product, its purpose (for night use, for day use), and its structure (with wings, without wings). Usually, the surface that faces forward when displayed is the front side. In addition, if the bottom surface 104 of the container 1 in the above-mentioned placed state (with the front sides arranged up and down) does not have a certain length, another state may be used as the placed state. Specifically, when the length of the short side among the sides constituting the lower surface 104 is within 30 mm, or when the length of the short side is shorter than the thickness of two packages 10, it is difficult to stand the container 1 with the lower surface as the bottom surface, so the state in which the front surface selected from the design is the top surface may be set as the placed state. In that case, the front surface selected from the design is set as the top surface 103. Also, when the container 1 does not have a gusset (not a so-called gusset fold) and the container joint 5 is formed on the surface (lower surface) below the front surface selected from the design, it is difficult to stand the container 1 with the lower surface on which the container joint 5 is located as the bottom surface, so the state in which the front surface selected from the design is the top surface may be set as the placed state. In that case, the front surface selected from the design is set as the top surface 103. In addition, if a gusset is formed on the lower surface (bottom surface) facing the front surface selected from the design, and a gusset is not formed on the upper surface (top surface) facing the front surface selected from the design, the container 1 is easily stood upright with the bottom surface as the bottom surface, so the placement state is defined with the front surface selected from the design as the front surface 101.

The container 1 may be a substantially rectangular parallelepiped as in this embodiment. In the placed state, the container 1 may have a front surface 101 and a back surface 102 that face each other, a top surface 103 located on the upper side, a bottom surface 104 located on the lower side, a left side surface 105 located on the left side, and a right side surface 106 located on the right side. The front surface 101 and the back surface 102 are surfaces that extend in the vertical direction X and the horizontal direction Y. The top surface 103 and the bottom surface 104 are surfaces that extend in the depth direction Z and the horizontal direction Y, and face each other. The left side surface 105 and the right side surface 106 are surfaces that extend in the vertical direction X and the depth direction Z, and face each other. The packaging body 10 in this embodiment is stacked in the thickness direction T, and the thickness direction T is along the horizontal direction Y. However, in a modified example, the thickness direction T may be along the depth direction Z.

The container 1 has a container joint 5 that joins the container sheets 2 together. The container joint 5 may be formed, for example, by heat welding. The container 1 may seal the package 10 by joining the container sheets 2 with the container joint 5. Here, the sealed state refers to a state in which the container is placed on a table or the like without any particular load and there is almost no change after 14 days. The container sheet 2 of this embodiment is formed into a cylindrical shape extending in the horizontal direction Y and contains the laminate 50, and the container sheets 2 are gusset-folded on the left side 105 and the right side 106 to join the container sheets 2 together. The container joint 5 is provided on the left side 105 and the right side 106, respectively, and extends in the vertical direction X. In a modified example, the container joint 5 may be provided on the upper surface 103 and the lower surface 104, respectively, and extend in the horizontal direction Y.

The container 1 may have an opening 9 for inserting and removing the package 10 during use. In this embodiment, the opening 9 is formed by a perforation. When in use, the user cuts the perforation to form an opening for inserting and removing the package 10. The openings 9 extend along the vertical direction X on the left side surface 105, and are arranged in a pair on either side of the container joint 5.

The packaging body 10 may contain the absorbent article 20 by joining the packaging sheet 12 with the packaging joint 15. The packaging state may be such that the entire absorbent article 20 is wrapped. With this configuration, the sanitary state of the absorbent article 20 can be maintained by the packaging sheet 12. Preferably, the packaging body 10 may seal the absorbent article 20 by joining the packaging sheet 12 with the packaging joint 15. With this configuration, the volatilization of the fragrance of the absorbent article 20 can be suppressed by the packaging sheet 12. The packaging body 10 shown in FIG. 4 is in an elongated state in which the packaging body 10 is taken out of the container 1 and elongated in a plan view. Generally, the packaging sheet 12 of the packaging body 10 is folded in the container 1 and covers the thickness portion of the packaging body 10. In the elongated state, the packaging body 10 is in a state in which the packaging sheet 12, which was folded in the container state, is stretched as much as possible.

The packaging body 10 has a first direction D1 and a second direction D2 perpendicular to the thickness direction T. In this embodiment, the first direction is along the width direction W of the absorbent article 20, and the second direction D2 is along the front-rear direction L of the absorbent article 20. In a modified example, the first direction D1 may be along the front-rear direction L, and the second direction D2 may be along the width direction W. In the packaging body 10, the packaging sheet 12 and the absorbent article 20 are folded multiple times from a fold FL extending in the first direction D1. The packaging joint 15 may have a pair of first packaging joints 151 that join the packaging sheets 12 arranged at both ends of the packaging body 10 in the first direction D1 in the folded state. The first packaging joints 151 may be formed, for example, by heat welding. In the second direction D2 perpendicular to the first direction D1, one end of the packaging sheet 12 is located inside the packaging body 10 in the folded state, and the other end is located on the outer surface of the packaging body 10. The packaging joint 15 may have a second packaging joint 152 that fastens the other end of the packaging sheet 12 (the edge located on the outer surface of the packaging body 10). In this embodiment, the second packaging joint 152 is a tape member, and only the center of the end of the packaging sheet 12 in the second direction D2 is joined. However, in a modified example, the second packaging joint 152 may be provided continuously in the second direction D2 by an adhesive such as an HMA type adhesive, heat welding, or the like.

The container 1 of the present embodiment is configured to provide the user with a fragrance before opening the package 10 while maintaining the hygienic state of the absorbent article 20 before use. In the placed state of the container 1, if the length of the stack 50 in the horizontal direction Y is C, the length of the stack 50 in the depth direction Z is D, and the horizontal length of the storage space in the container 1 that stores the stack 50 is F, (C ² +D ² ) ^1/2 >F may be satisfied. (C ² +D ² ) ^1/2 is the length Q of the diagonal of the stack 50. The thickness direction T of the absorbent article 20 is along either the horizontal direction Y or the depth direction Z of the stack 50. Therefore, the length Q of the diagonal of the stack 50 is the length of the diagonal on the surface where the multiple packages 10 are stacked. F is the length in the horizontal direction Y of the storage space 7. The size of the storage space 7 is defined by the inner surface of the storage sheet 2. Therefore, the length F of the storage space 7 in the horizontal direction Y is the distance in the horizontal direction Y between the inner surface of the storage sheet 2 on the left side surface 105 and the inner surface of the storage sheet 2 on the right side surface 106. In the embodiment in which the dimension F of the storage space 7 in the horizontal direction Y changes depending on the position in the depth direction Z, the length F may be the dimension at the center of the depth direction Z. In the embodiment in which the dimension F of the storage space 7 in the horizontal direction Y changes depending on the position in the vertical direction X, the length F may be the dimension at the center of the vertical direction X. For example, if the length F of the storage space 7 in the horizontal direction Y in the storage body 1 is longer than the length Q of the diagonal line of the laminate 50, the volume of the storage space 7 becomes too large compared to the volume of the laminate 50, and the fragrance volatilizes too much in the storage body 1, which may cause the user to be unable to fully apply the fragrance when using the absorbent article 20. However, since the volume of the storage space 7 is not too large compared to the volume of the laminate 50, excessive volatilization of the fragrance in the storage body 1 can be suppressed, and the absorbent article 20 can be stored for a long period of time.

In addition, even if (C ² +D ² ) ^1/2 > F is not satisfied, the difference (F-C) between the horizontal length F of the storage space 7 of the storage body 1 and the length C of the horizontal direction Y of the stack 50 in the placed state may be constant over the entire vertical direction X of the stack 50. When the difference (F-C) in the position of the lower surface side of the stack in the placed state, the difference (F-C) in the position of the upper surface side of the stack 50 in the placed state, and the difference (F-C) in the position of the center in the vertical direction X of the stack 50 in the placed state are constant, they may be considered to be constant over the entire vertical direction X. Here, in the present invention, the range in which the difference is constant includes not only a difference of 0 mm but also a predetermined range due to manufacturing errors. For example, a difference within a range of 5% (5% x F or 5% x C) with respect to one length, or a difference of 5 mm or less, is considered to be within the range in which the difference is constant. For example, if the difference between the length F of the storage space 7 in the horizontal direction Y and the length C of the laminate 50 in the horizontal direction Y changes significantly, a portion of the storage space 7 that is too long relative to the laminate 50 will be formed, causing too much volatilization of the fragrance in the storage body 1, and there is a risk that the fragrance will not be sufficiently applied to the user when using the absorbent article 20. In particular, when the length of the horizontal direction Y of the storage body 1 is longer than the length in the vertical direction X and the length in the depth direction Z, volatilization of the fragrance is more likely to occur. However, since the difference (F-C) is constant, the volume of the storage space 7 does not become too large compared to the volume of the laminate 50, so excessive volatilization of the fragrance in the storage body 1 can be suppressed, and the absorbent article 20 can be stored for a long period of time.

Furthermore, in the placed state, the difference (G-D) between the length G in the depth direction Z of the storage space 7 of the container 1 and the length D in the depth direction Z of the laminate 50 may be constant over the entire area in the vertical direction X of the laminate 50. With this configuration, the volume of the storage space does not become too large compared to the volume of the laminate 50, so excessive volatilization of the fragrance in the container 1 can be suppressed and long-term storage is also possible. More preferably, the container 1 satisfies ( ^C2 + ^D2 ) ^1/2 >F, and the difference (F-C) and the difference (G-D) may be constant.

The oxygen permeability of the storage sheet 2 is lower than that of the packaging sheet 12, and is 200 cc/m ² /day/atm or less at 23° C. The oxygen permeability of the storage sheet 2 has a predetermined oxygen permeability (200 cc/m ² /day/atm or less at 23° C.), that is, it has airtightness. Therefore, it is possible to suppress the volatilization of the fragrance from the storage body 1 during storage of the absorbent article 20. In addition, since the oxygen permeability of the packaging sheet 12 is higher than that of the storage sheet 2, the fragrance volatilizes through the packaging sheet 12, but is difficult to volatilize through the storage sheet 2. Therefore, when the storage body 1 is opened and before the packaging body 10 is opened, a part of the fragrance volatilizes outside the packaging body 10 and is given to the user. The user can enjoy the fragrance component of the fragrance in a state where the absorbent article is hygienically maintained by the packaging body 10. Thus, the fragrance can be applied to the user before opening the package 10 while maintaining the sanitary condition of the absorbent article prior to use.

The oxygen permeability of the receiving sheet 2 may be 100 cc/ ^m2 /day/atm or less, preferably 50 cc/ ^m2 /day/atm or less, and more preferably 25 cc/ ^m2 /day/atm or less at 23° C. The oxygen permeability of the packaging sheet 12 may be higher than 200 cc/ ^m2 /day/atm at 23° C. According to this configuration, since there is a large difference between the oxygen permeability of the packaging sheet 12 and the oxygen permeability of the receiving sheet 2, it becomes easier for the fragrance to remain in the receiving sheet 2 while volatilizing through the packaging sheet 12. The oxygen permeability is measured according to the coulometric method under conditions of 23° C. and 0% RH.

The storage sheet 2 may include a low oxygen permeability layer made of alumina-based vapor deposition or EVOH resin (ethylene-vinyl alcohol copolymer). The low oxygen permeability layer is configured to have a relatively low oxygen permeability. Specifically, for example, the storage sheet 2 may have a three-layer structure of a polyethylene layer, an EVOH layer, and a polyethylene layer, a three-layer structure of a polyethylene terephthalate layer, an aluminum foil layer, and a polyethylene layer, or a two-layer structure of an aluminum-like vapor deposition polyethylene layer and a polyethylene layer. Each layer may be bonded with an adhesive. On the other hand, the packaging sheet 12 may be a resin layer that does not include a low oxygen permeability layer. The packaging sheet 12 may be a film made of polyethylene or polyethylene terephthalate, or may be a nonwoven fabric. With this configuration, the difference between the oxygen permeability of the packaging sheet 12 and the oxygen permeability of the storage sheet 2 becomes larger, and it becomes easier for the fragrance to exist that volatilizes through the packaging sheet 12 but remains in the storage sheet 2.

At least a part of the packaging joint may be provided discontinuously. In a form having the first packaging joint 151 and the second packaging joint 152, at least one of them may be discontinuous. The first packaging joint 151 in this embodiment is formed by intermittent heat welding and is discontinuous. In addition, the second packaging joint 152 joins only a part of the end of the packaging sheet 12 in the second direction, and is not provided over the entire area of the packaging sheet 12 in the second direction. Therefore, the second packaging joint 152 is also discontinuous. According to this configuration, it is possible to maintain the hygienic state of the absorbent article 20 contained therein while partially volatilizing the fragrance in the contained state. In a modified example, the storage joint 5 may be provided continuously. According to this configuration, it is possible to increase the sealing property of the storage body 1 while decreasing the sealing property of the packaging body 10, and to volatilize the fragrance through the packaging body 10 while retaining the fragrance in the storage body 1 without volatilizing the fragrance through the storage sheet 2. In addition, when the packaging joint is discontinuous, the length of the discontinuous portion (the distance between the continuous portions) may be shorter than the length of the continuous portion, and from the viewpoint of suppressing the evaporation of the fragrance, may be less than 5 mm, and more preferably, may be less than 3 mm.

In a modified example, one of the first packaging joint 151 and the second packaging joint 152 may be provided continuously, and the other of the first packaging joint 151 and the second packaging joint 152 may be provided discontinuously. According to this embodiment, the fragrance in the packaging body 10 can be evaporated through the discontinuous packaging joint 15, while excessive evaporation of the fragrance can be suppressed through the continuous packaging joint 15. The amount of fragrance that is evaporated can be controlled, and the fragrance to be applied to the user when the container 1 is opened and the fragrance to be applied to the user when the packaging body 10 is opened can be appropriately provided.

The packaging joint 15 and the storage joint 5 extend in the extension direction and have a predetermined width in the orthogonal direction perpendicular to the extension direction. Specifically, the extension direction of the first packaging joint 151 is the second direction D2, and the orthogonal direction is the first direction D1. The extension direction of the storage joint 5 is the vertical direction X, and the orthogonal direction is the horizontal direction Y. The orthogonal length J15 of the packaging joint 15 may be shorter than the orthogonal length J5 of the storage joint 5. Since the orthogonal length J5 of the storage joint 5 is relatively long, the storage joint 5 is difficult to release, and the sealing property of the storage body 1 can be improved. On the other hand, since the orthogonal length J15 of the packaging joint 15 is relatively short, the sealing property of the packaging body 10 can be reduced while protecting the absorbent article from dust and dirt, and maintaining a hygienic state. In other words, the sealing property of the container 1 can be increased while the sealing property of the packaging body 10 can be decreased, and the fragrance can be vaporized through the packaging body 10 while remaining within the container 1 without vaporizing through the storage sheet 2.

In the expanded state of the packaging body 10, the distance H (see FIG. 4) between the outer edges of the pair of first packaging joints 151 in the first direction D1 may be longer than the length of the storage space 7 of the container 1 in the first direction D1. Also, the distance K between the inner edges of the pair of first packaging joints 151 in the first direction D1 may be shorter than the length of the storage space 7 in the first direction. The first direction of the storage space is determined along the fold direction of the packaging body 10, and in this embodiment, it is the depth direction. Therefore, the length of the first direction D1 of the storage space 7 is the depth direction length G of the storage space 7. Since the distance H between the outer edges of the first direction of the first packaging joints is longer than the length G of the storage space of the container 1 in the first direction, at least one of the pair of first packaging joints 151 is folded within the container 1. Therefore, by folding the packaging joint, the volatilization of the fragrance from the end of the first direction of the packaging body 10 can be suppressed, and it can be stored suitably for a long period of time. In addition, because the length between the inner edges of the first packaging joint in the first direction is shorter than the length of the storage space of the container 1 in the first direction, the packaging space of the package 10 sandwiched between the first packaging joint is less likely to be pressed by external forces within the container 1, suppressing deformation of the absorbent article inside and suppressing the evaporation of fragrance due to deformation of the absorbent article due to external forces.

The fragrance of the absorbent article is not particularly limited as long as it has a fragrance component and is volatile. However, preferably, the fragrance may be a cooling or warming agent that acts on the receptor-activated receptor (TRP) and contains a substance that has a vapor pressure of 0.01 mbar or less at 20°C. According to this aspect, by using a cooling or warming agent with low volatility, the user can enjoy the fragrance and feel the effect of a cooling or warming sensation. Examples of cooling agents acting on receptor-activated channels include menthone glycerin acetal (MGA), menthyl ethylamino oxalic acid, menthyl succinate, 3-(menthyloxy)propane-1,2-diol, 3-l-menthoxy-2-methylpropane-1,2-diol, N-ethyl-p-menthane-3-carboxamide, menthol (e.g., l-menthol (molecular formula: CHO)), its derivatives (e.g., menthyl lactate), eucalyptol, camphor, isopulegol, eucalyptus oil, peppermint oil, methyl salicylate, and p-menthane-3,8-diol. Examples of thermosensing agents that act on receptor-activated channels include psicoside, capsaicin, capsaicinoids (dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, homocapsaicin, nonivamide, etc.), capsanthin, benzyl nicotinate, β-butoxyethyl nicotinate, N-acyl vanillamide, nonanoic acid vanillylamide, polyhydric alcohols, chili pepper powder, chili pepper tincture, chili pepper extract, nonanoic acid vanillyl ether, vanillyl alcohol alkyl ether derivatives (e.g., vanillyl ethyl ether, vanillyl butyl ether, vanillyl pentyl ether, vanillyl hexyl ether), isovanillyl alcohol alkyl ether, ethyl vanillyl alcohol alkyl ether, veratorial alcohol derivatives, substituted benzyl alcohol derivatives, substituted benzyl alcohol alkyl ether, vanillin propylene glycol acetal, ethyl vanillin propylene glycol acetal, ginger extract, ginger oil, gingerol, and zingerone.

The absorbent article 20 may be a known absorbent article 20 as appropriate. However, it is preferable to use an absorbent article 20 having a relatively soft absorbent core. Specifically, the repulsive force in the thickness direction of the absorbent article may be 0.0539 N·cm ² or less. Here, the repulsive force is measured in a KES compression property test, and a compression tester, for example, KES (handy compression tester, model: KES-G5) manufactured by Kato Tech Co., Ltd., may be used, and the repulsive force can be measured by the following method. (1) The package 10 (one piece) is placed on the measurement table of the handy compression tester KES-G5. (2) The measurement parameters (DEF2mm/V, SENS200g, stroke50% (compressor area 2cm ² ), speed1mm/sec, range1) are set so that the measurement load is 50fg/cm ² . (3) The package 10 is pressurized with the above load for 3 cycles, and N=3 is measured. (4) The average energy when the package 10 is depressed by 1 mm during pressurization in the final cycle of the 3 cycles is taken as the repulsive force. According to this embodiment, the repulsive force of the absorbent article is low, and the absorbent article 20 is easily deformed when a force is applied from the outside of the package 10. Therefore, when the package 10 is carried, for example, the absorbent article inside the package 10 alone is deformed, and the deformation causes the fragrance of the absorbent article to volatilize, and the fragrance component can be imparted to the user.

The value of the bending stiffness B of the storage sheet 2 may be 0.25 g·cm ² /cm or less. The bending stiffness of the storage sheet 2 is relatively low, and it is easy to deform flexibly when an external force is applied. If the storage sheet 2 is in a form that is difficult to deform flexibly, the storage sheet 2 is easily broken by external pressure, and the internal scent components may escape, making it impossible to store for a long period of time. However, the storage sheet 2 is flexibly deformed to suppress unintended breakage, and it is possible to store the storage sheet for a long period of time while retaining the fragrance. The bending stiffness B can be measured by the following method. (1) The sheet to be measured (one sheet) is cut to 100 mm x 70 mm. (2) The sheet is placed on the measurement table of the pure bending tester KES-FB2-A and the sheet is clamped and fixed. (3) Measurement parameters are set (maximum bending rate 2.5, SENS 20). (4) The MD and CD of the sheet are measured, and the measured values of the MD and CD are averaged to obtain the bending stiffness B. The flexural rigidity B of the storage sheet 2 may be higher than the flexural rigidity B of the packaging sheet 12. The value of the flexural rigidity B of the packaging sheet 12 may be 0.001 g·cm ² /cm or more.

The thickness of the storage sheet 2 may be thicker than the thickness of the packaging sheet 12. This configuration also makes it possible to increase the sealing property of the storage body 1 while decreasing the sealing property of the packaging body 10, and to retain the fragrance in the storage body 1 without volatilizing the fragrance through the storage sheet 2 while volatilizing the fragrance through the packaging body 10. The thickness of the liquid-impermeable back sheet of the absorbent article may be thicker than the thickness of the packaging sheet 12. In the state of the packaging body 10, the back sheet inside the packaging sheet 12 can prevent the fragrance from volatilizing. In a modified example, the thickness of the liquid-impermeable back sheet of the absorbent article may be thinner than the thickness of the packaging sheet 12. When folding the packaging sheet 12 and the absorbent article together, the back sheet located inside the packaging body 10 is soft, making it easier to fold the packaging body 10. Therefore, in the state of the packaging body 10 after folding, the airtightness of the packaging body 10 is increased, and the volatilization of the fragrance can be suppressed.

The opening 9 of the container 1 may be arranged to face the plane extending in the front-rear direction L and the width direction W, rather than facing the thickness direction T. In the present embodiment, when the packages 10 of the stack 50 are stacked only in the thickness direction, multiple packages 10 are not arranged to face the opening 9 before the container 1 is opened, and only one package 10 is arranged to face the opening 9. Therefore, even if a small amount of air is let in or out through the opening 9, it is possible to prevent the fragrance in absorbent articles other than the absorbent article adjacent to the opening 9 from leaking out of the container 1.

When measuring the dimensions of the container 1, the stack 50, and the packaging body 10 in the placed state, the measurements are made as follows.
(1) When measuring the length F of the housing 1 in the horizontal direction Y and the length C of the stack 50 in the horizontal direction (thickness direction) Y, the housing 1 is placed on a flat surface with the lower surface 104 of the housing as the bottom surface. At this time, the stack 50 is placed so that it is located approximately in the center between the front surface 101 and the back surface 102 of the housing, and the stack 50 is located approximately in the center between the left side surface 105 and the right side surface 106 of the housing.
(2) When the storage joint 5 is not formed on the left side surface 105 and the right side surface 106 of the storage body 1, the length in the horizontal direction Y is measured from the outside of the storage body 1. When the thickness of the storage sheet 2 is less than 1 mm, the distance between the left side surface 105 and the right side surface 106 of the storage body 1 (the length in the horizontal direction Y of the storage body 1) is taken as the length in the horizontal direction Y of the storage space 7. At this time, the distance between the left side surface 105 and the right side surface 106 of the storage body 1 (the length in the horizontal direction Y of the storage body 1) is taken as the distance in the area overlapping with the laminate 50. When the thickness of the storage sheet 2 is 1 mm or more, the distance between the left side surface and the right side surface of the storage body 1 (the length in the horizontal direction Y of the storage body) is measured, and the length obtained by subtracting twice the thickness of the storage sheet 2 from the measured length is taken as the length in the horizontal direction Y of the storage space 7. When the storage joint 5 is formed on at least one of the left side surface 105 and the right side surface 106 of the storage body 1, the length excluding the storage joint 5 is taken as the length of the part.
(3) When the outer shape of the laminate 50 can be seen from outside the container 1, the length of the laminate 50 is measured from the outside of the container 1. When it is difficult to see the laminate 50 from the outside of the container 1, a light source such as an LED is applied from the outside of the container 1 to measure it. When the outer shape of the laminate 50 cannot be seen from the outside of the container 1, the position where the laminate 50 comes into contact with the packaging material when pressed from the outside of the container 1 with a hand or the like is regarded as the outer surface of the laminate. At this time, the thickness of the storage sheet 2 is taken into consideration, as in the measurement of the length of the storage space.
(4) The length Q of the diagonal of the stack 50 may be calculated by measuring the length C of the stack 50 in the horizontal direction Y and the length D of the stack 50 in the depth direction Z, and using the following formula: ( ^C2 + ^D2 ) ^1/2 = Q. Alternatively, if the outer shape of the stack 50 can be seen from outside the container 1, the length Q of the diagonal of the stack 50 may be measured directly.
(5) When measuring the package 10, the package is placed on a flat surface with the widest surface of the package (e.g., the surface extending in the front-to-back and width directions) as the bottom surface.
(6) The lengths of the container 1, the stack 50, and the packaging body 10 may be measured using a measuring instrument such as a long caliper or a ruler, or may be calculated based on an image taken.
