Description

Absorbent packaging

The present invention relates to an absorbent article package.

There is an absorbent article package (hereinafter also referred to as a sanitary napkin package) in which an absorbent article such as a sanitary napkin is folded and individually wrapped with a packaging sheet. There is known a method of giving a user a feeling of relaxation or changing a mood by adding a scent to a predetermined part of such a sanitary napkin package. For example, Patent Document 1 discloses a technique for perfume a sanitary napkin package by applying a fragrance to a release sheet (separator) provided between a sanitary napkin and a packaging sheet.

JP 2007-252886 A

As a method of perfume the sanitary napkin package, for example, when a separator is not provided, it is conceivable to apply a perfume to the packaging sheet. At this time, if the fragrance is applied to the outer surface side of the packaging sheet, the scent may be easily transferred to the outside. For example, when a user puts a sanitary napkin package in a bag or the like and conveys it, the scent may move to the bag. Therefore, when scenting a packaging sheet, it is desirable to apply a fragrance | flavor to the inner surface side of a packaging sheet.

However, in such absorbent articles (for example, sanitary napkins), there are many cases where an adhesive portion is formed so that the napkin is affixed to the user's underwear when the napkin is used so that positional displacement is less likely to occur. When the adhesive part of such a sanitary napkin comes into contact with the fragrance applied to the inner surface of the packaging sheet, due to the influence of the oil content of the fragrance, the adhesive part of the adhesive part is lowered and easily peeled off from the underwear. There is a risk that the agent may adhere to the underwear side.

The present invention has been made in view of the above problems, and the object of the present invention is to reduce the adhesiveness of the adhesive portion and to prevent the fragrance from being transferred to the outside. The object is to provide a scented absorbent article package.

The main invention for achieving the above object includes an absorber that absorbs liquid, a surface layer that covers the absorber from the user's skin side, and a back layer that covers the absorber from the non-skin side of the user. An absorbent article having an adhesive part on the back layer for attaching the absorbent article to underwear during use, and a packaging sheet for packaging the absorbent article, the absorbent article comprising: A wrapping sheet having a scented portion with a fragrance attached to the surface to be packaged, and in a state where the absorbent article is packaged by the wrapping sheet, the adhesive portion is not in contact with the scented portion. It is an absorbent article packaging body characterized by having.
Other features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

According to the present invention, it is possible to provide an absorbent article package in which a packaging sheet is scented so that the fragrance is not easily transferred to the outside without reducing the adhesiveness of the adhesive part.

At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
An absorbent article having an absorbent body that absorbs liquid, a surface layer that covers the absorbent body from the user's skin side, and a back surface layer that covers the absorbent body from the non-skin side of the user, An absorbent article having an adhesive portion on the back layer for attaching the absorbent article to an undergarment, and a packaging sheet for packaging the absorbent article, wherein the perfume is attached to the surface on the side of packaging the absorbent article. An absorbent article comprising: a packaging sheet having an incense part, wherein the adhesive part has a region not in contact with the aromatizing part in a state where the absorbent article is packaged by the packaging sheet. Packaging body.

According to such an absorbent article packaging body, a scent can be imparted to the packaging sheet portion so that the scent is not easily transferred to the outside without reducing the adhesiveness of the adhesive part of the absorbent article. .

The absorbent article packaging body has a lateral direction and a longitudinal direction intersecting the lateral direction, and the packaging sheet is a side on which the absorbent article is packaged based on a crease along the lateral direction. Folded in the vertical direction so that the surface of the packaging sheet is on the inside, a seal region for sealing the folded packaging sheets along the vertical direction is formed at both lateral ends of the packaging sheet, It is desirable that the perfume portion is formed between a region facing the adhesive portion and a region where the seal region is formed in the packaging sheet.

According to such an absorbent article packaging body, the perfume portion is less likely to come into contact with the adhesive portion and the seal region, and it is possible to suppress a decrease in adhesiveness of the adhesive portion and insufficient seal strength of the seal region. Moreover, it becomes easy to suppress that a fragrance transfers outside by a fragrance | flavor part being folded inside a packaging sheet.

In such an absorbent article package, it is desirable that the perfume portion is formed between the lateral end of the absorbent article and a region where the seal region is formed.

¡According to such an absorbent article packaging body, a lateral clearance can be provided between the perfume portion and the adhesive portion. The presence of the clearance makes it difficult for the scented portion and the adhesive portion to come into contact with each other even when the scented portion is formed slightly deviated laterally.

In such an absorbent article package, it is desirable that the perfume portion is formed along the vertical direction while having a predetermined length in the horizontal direction.

According to such an absorbent article packaging body, in the manufacturing process of the absorbent article packaging body, the fragrance ink is ejected to the packaging sheet conveyed along the longitudinal direction (conveying direction) using an inkjet nozzle or the like. Thereby, it becomes easy to attach a fragrance | flavor and can form a fragrance | flavor part efficiently.

In such an absorbent article package, the perfume portion is formed in a region sandwiched between the opposed packaging sheets in a state where the packaging sheet is folded with the fold as a base point. desirable.

According to such an absorbent article package, since the scented part is covered with the packaging sheet, the fragrance component adhering to the scented part leaks out of the absorbent article package. It becomes easy to suppress.

Such an absorbent article packaging body has a thickness direction intersecting with the longitudinal direction and the lateral direction, and in a state where the absorbent article packaging body is folded, the thickness is greater than the outside in the thickness direction. It is desirable that the amount of perfume adhering per unit area of the packaging sheet is larger on the inner side in the vertical direction.

According to such an absorbent article packaging body, the concentration of the fragrance becomes thinner as the position is closer to the outside of the absorbent article packaging body, and the fragrance is located at a position farther from the outside of the absorbent article packaging body (that is, the inner side in the thickness direction). Since the density | concentration of becomes high, it becomes difficult for a fragrance to leak to the exterior of an absorbent article packaging body, and it becomes easy to suppress that a fragrance transfers to a wrinkle.

In such an absorbent article package, a separator that is releasably attached to the adhesive portion is provided between the perfume portion and the adhesive portion, and between the separator and the packaging sheet. It is desirable that an adhesive part for adhering the separator and the packaging sheet is provided.

</ RTI> According to such an absorbent article package, the separator suppresses direct contact between the perfume portion and the adhesive portion. In addition, since the separator is bonded to the packaging sheet, when the napkin is used, the separator can be removed together simply by peeling the packaging sheet from the napkin.

In such an absorbent article package, it is desirable that the perfume portion has a region not in contact with the adhesive portion in a state where the absorbent article is packaged by the packaging sheet.

According to such an absorbent article packaging body, it is suppressed that the adhesive strength of the said adhesion part weakens resulting from the oil part of the fragrance | flavor which forms a scent part, and the adhesive agent of an adhesion part contacting. The Thereby, it becomes easy to suppress that problems, such as a separator peeling from a packaging sheet, arise.

In such an absorbent article package, it is desirable that the packaging sheet is formed of a film or an SMS nonwoven fabric.

According to such an absorbent article packaging body, it is suppressed that the fragrance | flavor adhering to the inner side of a packaging sheet moves outside by the film which has the property which does not permeate | transmit the particle | grains of a fragrance | flavor, and the melt blown layer of SMS nonwoven fabric. Is done. Therefore, it becomes easy to suppress that a fragrance transfers from an aroma part to the exterior of an absorbent article packaging body.

=== Embodiment ===
<Configuration of sanitary napkin package>
A sanitary napkin package 1 will be described as an example of an individual package in which absorbent articles are individually packaged. In the following description, a sanitary napkin will be described as an example of the absorbent article. However, the absorbent article of the present embodiment also includes a so-called cage sheet (for example, a panty liner) and the like. It is not limited. FIG. 1 is an exploded perspective view illustrating the configuration of the sanitary napkin package 1. FIG. 2 is a schematic sectional view showing the AA section of FIG. FIG. 3 is a diagram illustrating the sanitary napkin package 1 in a folded state.

The sanitary napkin package 1 includes a sanitary napkin 10, a packaging sheet 20, and a separator 30. In the following description, each direction is defined as shown in FIG. That is, the direction along the product longitudinal direction of the sanitary napkin 10 is defined as “vertical direction”. The vertical direction has a “front side” and a “rear side”. The “front side” is a direction that becomes the stomach side of the user when the sanitary napkin 10 is used, and the “rear side” is a direction that becomes the back side of the user when the sanitary napkin 10 is used. In addition, a direction orthogonal to the vertical direction, that is, a direction along the product width direction is referred to as a “lateral direction”. The direction perpendicular to the vertical direction and the horizontal direction is the “thickness direction”, and the side that contacts the wearer's skin when the sanitary napkin 10 is worn (the upper side in FIG. 1) is the “skin side” and the opposite side ( The lower side in FIG. 1 is defined as “non-skin side”.

As shown in FIG. 1, the sanitary napkin package 1 has a packaging sheet 20, a separator 30, and a sanitary napkin 10 stacked in order from the non-skin side in the thickness direction. In this state, the sanitary napkin 10 is folded with the sanitary napkin 10 inside, whereby the sanitary napkin package 1 is formed in a state where the sanitary napkin 10 is folded and individually wrapped as shown in FIG. . The separator 30 is not an essential component, and the sanitary napkin package 1 may be configured by the sanitary napkin 10 and the packaging sheet 20.

(Sanitary napkin 10)
A sanitary napkin 10 (hereinafter also simply referred to as “napkin 10”) absorbs liquid 11, a surface layer 12 covering the absorber 11 from the user's skin side, and absorbs from the user's non-skin side. And a back surface layer 13 covering the body 11 (see FIG. 2).

The absorbent body 11 is a vertically long member extending in the vertical direction, and includes hydrophilic fibers, pulp, and the like, and can efficiently absorb and retain a liquid such as a body fluid. The absorbent body 11 may be formed by laminating hydrophilic fibers or powders by the airlaid method, or may be an airlaid sheet obtained by forming hydrophilic fibers or powders into a sheet shape by the airlaid method.

The surface layer 12 is a liquid-permeable sheet member that allows liquid such as body fluid to pass through, and is formed of, for example, a nonwoven fabric. However, the material is not particularly limited as long as it is a sheet member having a structure that allows liquid to pass therethrough and is a safe member when coming into contact with the user's skin when the napkin 10 is used. For example, a woven fabric or a mesh sheet may be used. The surface layer 12 is larger than the absorber 11 in the vertical direction and the horizontal direction, and can cover the entire region of the absorber 11.

The back layer 13 is a non-liquid permeable sheet member, for example, a breathable resin film bonded to a non-woven fabric such as a film mainly made of polyethylene or propylene, a breathable resin film, spunbond, or spunlace. Formed by a sheet. Since the back surface layer 13 is non-liquid permeable, the liquid absorbed through the surface layer 12 and absorbed by the absorbent body 11 when the napkin 10 is used oozes out to the clothing side (non-skin side) such as underwear. It is suppressed. The back surface layer 13 has substantially the same shape as the surface layer 12 and desirably has such flexibility that does not cause the user to feel uncomfortable when using the napkin 10.

Further, an adhesive portion 131 is formed on the non-skin side of the back surface layer 13 in the thickness direction. The adhesive part 131 is a part having a function of sticking the napkin 10 to the user's underwear when the napkin 10 is used so that the position does not shift. The adhesive portion 131 is formed by applying an adhesive such as a hot melt adhesive (hereinafter also referred to as HMA) to a predetermined region of the back surface layer 13. The HMA that forms the adhesive portion 131 is such that when the napkin 10 is used, the affixed portion is not easily peeled off or displaced, and after the napkin 10 is used, the underwear is removed when the napkin 10 is removed from the underwear. The HMA is applied with a basis weight that does not leave HMA on the side (that is, no adhesive residue is generated). In the present embodiment, the adhesive portion 131 has a substantially rectangular shape that is vertically long along the vertical direction while having a predetermined width in the horizontal direction according to the shape of the absorbent body 11 (see FIG. 4 described later). ), The shape of the adhesive portion 131 is not limited to this. For example, the adhesive portion 131 may be formed by arranging a plurality of HMAs applied in a thin strip along the vertical direction in the horizontal direction.

The napkin 10 is formed by joining the peripheral edges of the surface layer 12 and the back surface layer 13 with the absorber 11 sandwiched in the thickness direction.

(Packaging sheet 20)
The packaging sheet 20 is a sheet-like packaging member for individually packaging the napkin 10 and is a member that is removed when the napkin 10 is used. The packaging sheet 20 includes a surface on which the napkin 10 is packaged, that is, a packaging surface 21 which is a surface facing the napkin 10 during packaging, and an outer surface 22 which is a surface opposite to the packaging surface 21 (see FIG. 2). Examples of the material of the packaging sheet 20 include various films such as a plastic film and a nylon film, a nonwoven fabric, a film obtained by laminating a nonwoven fabric, and the like.

The packaging sheet 20 of the present embodiment has a rectangular shape, and has a size that can cover the entire napkin 10 when the napkin 10 is folded (see FIG. 2). In addition, in a predetermined region of the packaging surface 21, an aroma unit 25 to which a fragrance is attached is provided. Details of the perfume unit 25 will be described later.

(Separator 30)
The separator 30 is a sheet member disposed between the adhesive portion 131 formed on the back layer 13 of the sanitary napkin 10 and the packaging surface 21 of the packaging sheet 20 (see FIG. 2). The separator 30 is a surface that contacts the back surface layer 13 of the napkin 10, a surface that is opposite to the surface 31, and a surface that contacts the packaging surface 21 of the packaging sheet 20 via the adhesive portion 41. A bonding surface 32.

The peeling surface 31 is peeled using silicon resin or the like, and is attached to the adhesive portion 131 of the napkin 10 so as to be peelable. Since the peeling process is known, a description thereof will be omitted. On the other hand, the bonding surface 32 is bonded to the packaging surface 21 of the packaging sheet 20 via the bonding portion 41. The adhesive portion 41 is formed by applying an adhesive such as a hot melt adhesive (HMA) to at least one predetermined region of the separator 30 and the packaging sheet 20. The bonding portion 41 is applied with a basis weight that does not easily peel off the separator 30 and the packaging sheet 20.

By arranging the separator 30 between the adhesive part 131 of the napkin 10 and the packaging surface 21 of the packaging sheet 20, an adhesive (for example, HMA) that forms the adhesive part 131 before the napkin 10 is used is applied to the packaging sheet 20. Adhesion and weakening of the adhesiveness of the adhesive part 131 are suppressed, and the adhesive part 131 is protected. And when using the napkin 10, by peeling off the packaging sheet 20 from the napkin 10, the separator 30 adhere | attached on the packaging sheet 20 can be removed with the packaging sheet 20, and the adhesive part 131 can be exposed easily. it can.

In addition, when the packaging surface 21 of the packaging sheet 20 can be affixed to the adhesive part 131 of the napkin 10 such that the packaging surface 21 of the packaging sheet 20 is peeled, the separator 30 is not necessarily provided. It does not have to be provided.

As shown in FIG. 1, the sanitary napkin package 1 is provided with a first fold F1 and a second fold F2 along the lateral direction. The first fold F1 is disposed on the rear side of the center in the longitudinal direction of the napkin 10, and the packaging sheet 20, the separator 30, and the sanitary napkin 10 are bent together with the first fold F1 as a base point. The 2nd fold F2 is arrange | positioned ahead rather than the center of the vertical direction of the napkin 10, and the packaging sheet 20, the separator 30, and the sanitary napkin 10 are bend | folded together by using the said 2nd fold F2 as a base point. Moreover, about the edge part of the vertical direction of the packaging sheet 20, let the vertical direction front side edge part be 20ea, and let the vertical direction rear side edge part be 20eb.

FIG. 3 is a diagram showing the sanitary napkin package 1 in a folded state. The sanitary napkin packaging body 1 is folded in the longitudinal direction so that the surface layer 12 is on the inside in the order of the first fold line F1 and the second fold line F2, so that the napkin 10 is formed by the packaging sheet 20 as shown in FIG. It will be covered. In this state, both end portions in the horizontal direction of the packaging sheet 20 are sealed along the vertical direction, and a seal region 27 is formed. The seal region 27 is formed using a known sealing means such as ultrasonic welding or heat welding. Thereby, the folded packaging sheets 20 are joined at both lateral ends, and the sanitary napkin package 1 is maintained in a folded state as shown in FIG. Moreover, the fixing tape 28 is stuck to the horizontal direction center part of the packaging sheet 20 so that the vertical direction front side edge part 20ea may be straddled. The fixing tape 28 is affixed to the outer surface 22 of the packaging sheet 20 so as to be peelable, whereby the packaging sheet 20 is peeled off before the napkin 10 is used or the sanitary napkin package 1 is unfolded. It is suppressed.

When the user uses the napkin 10, first, the fixing tape 28 is peeled off, and the sanitary napkin package 1 is developed so as to peel off the portion sealed by the seal region 27. Thereafter, the packaging sheet 20 and the separator 30 are separated from the napkin 10 by pulling the packaging sheet 20 to the opposite side in the thickness direction with respect to the napkin body 10. Thereby, the back surface layer 13 and the adhesion part 131 of the napkin 10 are exposed, and the napkin 10 is in a usable state.

<About the perfume unit 25>
In this embodiment, the fragrance | flavor part 25 to which the fragrance | flavor was made to adhere to the predetermined area | region of the packaging sheet 20 was provided, and the napkin 10 is packaged by the package sheet 20 by which the fragrance | flavor was carried out. A fragrance can be added. That is, a safe scented napkin in which no fragrance is directly attached to the napkin 10 can be provided.

In the sanitary napkin package 1, if the flavoring portion 25 is provided on the outer surface 22 side of the packaging sheet 20, the fragrance is attached to the outer surface of the sanitary napkin package 1 in the folded state. . In this case, when the sanitary napkin package 1 is transported in a bag or the like, the scent of the surface is easily transferred to the bag or when the user uses the sanitary napkin package 1, the scent is transferred to the hand. May be easier. Moreover, there exists a possibility that the component of a fragrance | flavor may become easy to volatilize.

Therefore, in the present embodiment, an aroma unit 25 is provided on the packaging surface 21 side of the packaging sheet 20. In the state (state of FIG. 3) where the sanitary napkin packaging body 1 is folded, the fragrance portion 25 is provided on the inner surface side (packaging surface 21 side) of the packaging sheet 20, thereby making it difficult for the scent to move to the outside. Moreover, it becomes easy to suppress volatilization of a fragrance | flavor component. In addition, as a method of attaching a fragrance (attaching a fragrance | flavor) to the packaging sheet 20, the method of apply | coating the liquid (for example, fragrance | flavor ink) containing a fragrance | flavor to the surface of the packaging sheet 20 using liquid discharge apparatuses, such as an inkjet printer, for example. Is mentioned.

On the other hand, when providing the fragrance | flavor part 25 in the packaging surface 21 side of the packaging sheet 20, attention is required about the area | region where a fragrance | flavor is actually attached among the packaging surfaces 21. As described above, the packaging surface 21 of the packaging sheet 20 is in contact with the adhesive part 131 formed on the back surface layer 13 of the napkin 10 and the adhesive part 41 provided between the separator 30 in at least a part of the area. there's a possibility that. An adhesive such as HMA is applied to the adhesive portion 131 and the adhesive portion 41. When this HMA comes into contact with the fragrance of the scented portion 25, the resin constituting the HMA reacts with the oil component contained in the fragrance. As a result, the adhesive strength of the HMA may be reduced, and the napkin 10 may not be firmly attached to the undergarment, or the separator 30 may be peeled off from the adhesive portion 41 before the napkin 10 is used. In addition, there is a possibility that “glue residue” that the HMA is detached from the adhesive portion 131 and adheres to the underwear, and the underwear is soiled.

Moreover, when the fragrance | flavor of the fragrance | flavoring part 25 has adhered to the seal | sticker area | region 27 (refer FIG. 3) formed in the horizontal direction both ends of the packaging sheet 20 when folding the sanitary napkin packaging body 1, ultrasonic welding etc. There is a possibility that sufficient welding strength cannot be obtained when performing the above.

Therefore, in the present embodiment, the fragrance portion 25 is formed in a region that is difficult to contact the adhesive portion 131, the adhesive portion 41, and the seal region 27 on the packaging surface 21 of the packaging sheet 20.

FIG. 4 is a plan view for explaining a region where the perfume portion 25 is formed when the separator 30 is not provided. When the separator 30 is not provided in the sanitary napkin package 1, the adhesive portion 131 of the napkin 10 is in direct contact with the packaging surface 21 of the packaging sheet 20. In this case, on the packaging surface 21 of the packaging sheet 20, the perfume portion 25 needs to be formed so as to have a region that does not contact the adhesive portion 131. In other words, the adhesion part 131 needs to have an area | region which does not contact the perfume part 25. FIG. Further, since both end portions in the lateral direction of the packaging sheet 20 are portions where the seal region 27 is formed, the perfume portion 25 is formed so as to have a region that does not contact the seal region 27. In the example of FIG. 4, in the sanitary napkin package 1 in the unfolded state, an adhesive portion 131 is formed in a rectangular region indicated by a hatched portion near the center portion, and the hatched portions at both lateral ends of the packaging sheet 20 A seal region 27 is formed in the region indicated by. Therefore, the scented portion 25 is formed so as to have a region that does not overlap at least the region indicated by the hatched portion and the shaded portion in FIG.

FIG. 5A is a diagram illustrating a specific example of the aroma portion 25 actually formed. In FIG. 5A, on the packaging surface 21 of the packaging sheet 20, the scented portion 25 indicated by the hatched portion is formed between the region facing the adhesive portion 131 and the region where the seal region 27 is formed. As shown in FIG. 5A, the scented portion 25 is a vertically long belt-like region having a width H1 in the horizontal direction and extending in the vertical direction. The reason why the fragrance portion 25 is formed in a vertically long band shape is to efficiently attach the fragrance to the packaging sheet 20 in the manufacturing process of the sanitary napkin package 1. In the manufacturing process of the sanitary napkin package 1, the sheet member such as a nonwoven fabric which is a raw material of the packaging sheet 20 is conveyed in the conveying direction (direction along the vertical direction) on the conveying line in a state where the sheet members are continuously connected in the vertical direction. Is done. A fragrance | flavor is discharged with respect to this conveyed sheet | seat member from the some inkjet nozzle arrange | positioned along the crossing direction which cross | intersects a conveyance direction. The fragrance discharged from each nozzle lands on the sheet member to be conveyed, and forms a belt-like fragrance 25 having a predetermined width (here, H1) in the intersecting direction and along the conveying direction (vertical direction). To do.

FIG. 5B is a diagram illustrating an example in which FIG. 5A is modified. In FIG. 5B, the fragrance | flavor part 25 is an area | region displayed with the oblique line part which has the width | variety H2 in the horizontal direction. H2 is narrower than H1 (H1> H2), and in FIG. 5B, is a region sandwiched between the position of the lateral end of the napkin 10 and the seal region 27. As described above, the perfume portion 25 of the present embodiment is formed by applying a perfume to the packaging sheet 20 (sheet member) conveyed in the manufacturing process of the sanitary napkin package 1 by a method such as inkjet. . If meandering occurs in the process of transporting the packaging sheet 20 and the position in the cross direction (lateral direction) is shifted, the position in the horizontal direction of the scented portion 25 is shifted and the scented portion 25 and the adhesive portion 131 are formed. There is a risk of duplication. It is also conceivable that the position in the lateral direction is shifted in the process of overlaying the packaging sheet 20 on the adhesive portion 131 of the napkin 10. Therefore, in FIG. 5B, a lateral clearance is provided between the scented portion 25 and the adhesive portion 131 so that even if the position where the scented portion 25 is formed is slightly shifted, it is difficult to contact the adhesive portion 131. ing.

It should be noted that the scented portion 25 does not necessarily have a vertically long strip shape. For example, in FIG. 4, the scented portion 25 may be formed in all regions other than the adhesive portion 131 and the seal region 27, or the scented portion 25 may be formed in a horizontally long strip shape. good. Further, the fragrance forming the fragrance portion 25 does not have to be in a so-called “solid” state. The incense part 25 may be formed. In this case, since it becomes easy to adjust the quantity of the fragrance | flavor made to adhere per unit area, it becomes possible to adjust the intensity | strength of fragrance for every area | region in the sanitary napkin package 1.

Next, FIG. 6 is a plan view for explaining a region where the perfume portion 25 is formed when the separator 30 is provided. When the separator 30 is provided in the sanitary napkin package 1, the separator 30 is interposed between the adhesive portion 131 of the napkin 10 and the packaging surface 21 of the packaging sheet 20. Is unlikely to come into direct contact. On the other hand, since the adhesion part 41 is provided between the separator 30 and the packaging surface 21 of the packaging sheet 20, the perfume part 25 needs to be formed so as to have a region that does not contact the adhesion part 41. In the example of FIG. 6, the adhesive portion 41 is formed by a plurality of rectangular regions indicated by hatched portions in the sanitary napkin package 1 in the unfolded state, and the hatched portions at both lateral ends of the packaging sheet 20. A seal area 27 is formed in the area shown. Therefore, the scented portion 25 is formed so as to have at least a region that does not overlap with the region indicated by the hatched portion and the shaded portion in FIG.

FIG. 7A is a diagram illustrating a specific example of the scented portion 25 that is actually formed when the separator 30 is provided. In FIG. 7A, the scented portion 25 is formed in the region indicated by the hatched portion between the adhesive portion 41 and the seal region 27 on the packaging surface 21 of the packaging sheet 20. As shown in FIG. 7A, the perfume portion 25 is a vertically long strip-like region having a width H3 in the horizontal direction and extending along the vertical direction. The length of H3 is determined according to the lateral length of the bonding portion 41. The size of the adhesive portion 41 can be formed smaller than the adhesive portion 131 by increasing the basis weight when applying the adhesive. Therefore, as shown in FIG. 7A, the lateral length of the bonding portion 41 can be made narrower than the lateral length of the adhesive portion 131. In this case, since H3> H1, the scent portion 25 can be made larger than in the case of FIG. 5A (see FIGS. 5A and 7A). That is, by providing the separator 30, the range in which the scented portion 25 can be formed can be widened.

FIG. 7B is a diagram illustrating an example in which FIG. 7A is modified. Similarly to the case of FIG. 5B, the scented portion 25 is formed in a region sandwiched between the position of the lateral end of the napkin 10 and the seal region 27. In FIG. 7B, the scented portion 25 is a vertically long strip-like region having a lateral width H2 and extending along the longitudinal direction. H2 is narrower than H3 (H3> H2), and since the lateral clearance between the scented portion 25 and the bonded portion 41 is increased, even if the formation position of the scented portion 25 is slightly shifted, It becomes difficult for the scenting part 25 to contact.

By forming the scented part 25 in this way, the adhesive part 131 or the adhesive part 41 and the scented part 25 are less likely to come into contact with each other, and the adhesiveness of the adhesive part 131 (adhesive part 41) is prevented from decreasing. The Moreover, since the perfume part 25 is formed in the packaging surface 21 side of the packaging sheet 20, in the state which folded the sanitary napkin packaging body 1 like FIG. Since it is folded, the scent becomes difficult to transfer to the outside. In particular, when a film or an SMS nonwoven fabric (spunbond-meltblown-spunbond nonwoven fabric) is used as the material of the packaging sheet 20, a remarkable effect can be obtained. Since the surface of the film and the melt-blown layer of the SMS nonwoven fabric have the property of not allowing perfume particles to permeate, the perfume adhering to the inner side (packaging surface 21 side) of the packaging sheet 20 is easily suppressed from moving outward. Because it becomes.

<Modified example of napkin 10>
Although the sanitary napkin having the shape shown in FIG. 1 has been described as an example of the napkin 10 constituting the sanitary napkin package 1, the sanitary napkin may have various shapes depending on the application. Below, the case where the form of the napkin 10 differs as a modification of the sanitary napkin package 1 is demonstrated.

FIG. 8A and FIG. 8B are diagrams for explaining a modification of the sanitary napkin 10. In FIG. 8A, in the vicinity of the central portion in the vertical direction of the sanitary napkin 10, a wing portion 15 is provided in which the front surface layer 12 and the back surface layer 13 extend outward from both lateral ends. On the back layer 13 side of the wing part 15, a wing part adhesive part 151 to which an adhesive such as HMA is applied is provided in the same manner as the adhesive part 131. When using the napkin 10, after sticking the adhesive part 131 of the napkin 10 to the inside of the crotch part of the underwear, the wing part 15 is bent to the back layer 13 side and the wing part adhesive part 151 is attached to the outside of the crotch part of the underwear. To do. Thereby, the napkin 10 is fixed so that the crotch part of the underwear is sandwiched between the adhesive part 131 and the wing part adhesive part 151, and it becomes easy to suppress misalignment during use. Further, in FIG. 8B, in addition to having the wings 15, in the region on the rear side in the vertical direction of the napkin 10, a buttock cover 16 in which the front surface layer 12 and the back surface layer 13 spread in the horizontal direction and the vertical direction is provided. ing. The buttock cover 16 covers the user's buttock widely when the napkin 10 is used, so that liquids such as body fluids are prevented from leaking to the outside of the napkin 10 at the buttock and the underwear is soiled. It can be made difficult to occur.

9A to 9D are diagrams illustrating an example of how to fold the sanitary napkin package 1 in the case of a modification. 9A to 9D, the napkin having the form shown in FIG. 8A will be described as an example of the napkin 10 having the wings 15. However, the napkin having the form having the collar cover 16 shown in FIG. This modification can also be applied to napkins.

When the napkin 10 has the wings 15, the release sheet 50 is used when the sanitary napkin package 1 is folded. The release sheet 50 is a sheet member that is detachably attached to the wing adhesive section 151 and has the same function as the separator 30 for the adhesive section 131. That is, the adhesive (HMA or the like) of the wing adhesive part 151 is prevented from adhering to other parts, and the surface of the wing adhesive part 151 is protected.

FIG. 9A is a diagram showing the sanitary napkin package 1 in the unfolded state. In the sanitary napkin package 1 of the modified example, in addition to the first fold line F1 and the second fold line F2, a third fold line F3 along the lateral direction is provided. The third fold line F3 is arranged on the rear side in the vertical direction with respect to the first fold line F1, and at the third fold line F3, similarly to the first fold line F1 and the second fold line F2, the packaging sheet 20, the separator 30, And the sanitary napkin 10 is folded together. Further, a release sheet 50 is provided in a region on the rear side in the longitudinal direction from the third fold line F3 of the packaging sheet 20. Part of the release sheet 50 is bonded to the outer surface 22 side of the packaging sheet 20 and is disposed so as to protrude from the longitudinal rear end 20eb of the packaging sheet 20. Since the release sheet 50 is adhered to the packaging sheet 20, when the napkin 10 is used, the release sheet 50 is peeled off from the napkin 10 at the same time by peeling the packaging sheet 20 from the unfolded sanitary napkin package 1. It can be easily detached.

FIG. 9B is a diagram illustrating a state in which the sanitary napkin package 1 in the unfolded state is folded at the third fold F3. As shown in FIG. 9B, the napkin 10 is folded so that the surface layer 12 is on the inner side with the third fold F3 as a base point, and the release sheet 50 protruding from the longitudinal rear end 20eb of the packaging sheet 20 is The positional relationship is such that it overlaps the surface layer 12 of the napkin 10. At this time, the wing part 15 is also folded inward (surface layer 12 side), and the wing part adhesive part 151 is exposed to the skin side in the thickness direction.

Subsequently, FIG. 9C is a diagram illustrating a state in which the sanitary napkin package 1 is folded from the state of FIG. 9B at the first fold F1. The napkin 10 folded at the third fold F3 is further folded with the first fold F1 as a starting point, and a region of the release sheet 50 that protrudes from the longitudinal rear end 20eb of the packaging sheet 20 is a wing portion of the napkin 10. It will be in the state where it overlaps with 15 wing part adhesion parts 151. That is, a part of the release sheet 50 is affixed to the wing adhesive portion 151 and the wing adhesive portion 151 is protected. Finally, the sanitary napkin package 1 is folded with the second fold F2 as a base point so that the surface layer 12 of the napkin 10 is on the inside.

FIG. 9D is a diagram illustrating the sanitary napkin package 1 in a folded state according to a modification. In the folded sanitary napkin package 1, the sealing region 27 is formed by sealing both ends of the packaging sheet 20 in the vertical direction. And the fixing tape 28 is affixed on the center part of the packaging sheet 20 in the horizontal direction.

In the above-described embodiment, the sanitary napkin packaging body 1 is folded at two locations of the first fold line F1 and the second fold line F2 (see FIG. 2). The body 1 is folded at three places, the first fold line F1 to the third fold line F3. Such a folding method is an example, and the sanitary napkin package 1 may be folded so as to have four or more folds.

FIG. 10 is a diagram for explaining a specific example of the scented portion 25 actually formed when the separator 30 is not provided in the modification. Even in the case where the napkin 10 has the wings 15, the horizontal surface H1 is displayed in a hatched portion in a region between the region facing the adhesive portion 131 and the seal region 27 on the packaging surface 21 of the packaging sheet 20. A perfume portion 25 having a width is formed. Moreover, FIG. 11 is a figure explaining the specific example of the aroma part 25 actually formed when the separator 30 is provided in the modification. Since the adhesive part 131 is covered by the separator 30, the width of H3 is set in the lateral direction as indicated by the hatched part in the area between the adhesive part 41 and the seal area 27 on the packaging surface 21 of the packaging sheet 20. The fragrance | flavor part 25 which has is formed.

If the fragrance portion 25 is formed in such a region, the fragrance portion 25 and the adhesive portion 131 (or the adhesive portion 41) do not come into contact with each other when the sanitary napkin package 1 is folded, and the adhesive portion 131 ( It is suppressed that the adhesive force of the adhesive part 41) is reduced. Moreover, since the perfume part 25 is provided inside the folded packaging sheet 20, it is suppressed that a fragrance transfers to the exterior of the sanitary napkin package 1. FIG.

In the case of the modified example, as described with reference to FIG. 5B, the aroma portion 25 is formed in the region sandwiched between the position of the lateral end of the napkin 10 and the seal region 27. Also good. That is, a lateral clearance may be provided between the scented portion 25 and the adhesive portion 131 or the adhesive portion 41.

Further, as shown in FIG. 11, in the modified example, the fragrance portion 25E is formed in a range having a length of 2L in the vertical direction across the third fold line F3. FIG. 12 is a schematic cross-sectional view showing the BB cross section of FIG. 9D. FIG. 12 shows a state in which the sanitary napkin package 1 is folded. At this time, the sanitary napkin package 1 is shown in a black portion between the third fold F3 and the longitudinal rear end 20eb of the packaging sheet 20. A scent portion 25E is formed. The perfume portion 25E is formed so as not to contact the adhesive portion 131 (or the adhesive portion 41) and to be inside the folded packaging sheet 20. That is, the scent portion 25E is formed in a region sandwiched between the packaging sheets 20 facing each other by being folded. Thus, by forming the fragrance | flavor part 25E inside the packaging sheet 20, since the said fragrance | flavor part 25E will be in the state covered with the packaging sheet 20, a fragrance is hard to leak to the outer side of the sanitary napkin package 1. Become. Furthermore, in the region between the third fold line F3 and the longitudinal rear end 20eb, both sides in the thickness direction of the scented portion 25E are covered with the napkin 10, the separator 30, and the packaging sheet 20, respectively. In other words, the scent portion 25E is covered with a plurality of members in the thickness direction. Therefore, the scent of the scented portion 25E is difficult to leak to the outside.

=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof. For example, the following modifications are possible.

<About the formation of the scented part>
In the above-described embodiment, when forming the perfume portion 25 on the packaging surface 21 side of the packaging sheet 20, the fragrance is discharged to a predetermined region of the packaging surface 21 by discharging the fragrance using a liquid discharge device such as an ink jet printer. However, the method of forming the scented portion 25 is not limited to this. For example, the method of applying a fragrance | flavor directly to the packaging surface 21 using a brush etc. may be used. Alternatively, a method in which a fragrance is attached to a thin sheet member in advance and the sheet member to which the fragrance is attached is attached to a predetermined region of the packaging surface 21 may be used. In any case, the perfume part 25 is formed by attaching a fragrance | flavor to the predetermined area | region by the side of the packaging surface 21 of the packaging sheet 20, and hold | maintaining stably.

<About folding method of sanitary napkin packaging body 1>
In the above-described embodiment, the example in which the sanitary napkin packaging body 1 is folded in the vertical direction using a plurality of folds along the lateral direction as the starting point has been described. Absent. For example, the sanitary napkin packaging body 1 may be folded in the horizontal direction with a fold along the vertical direction as a base point, or may be folded in both the vertical direction and the horizontal direction.

<About release sheet 50>
In the above-described embodiment, when the napkin 10 has the wing part 15, the release sheet 50 is provided to protect the wing part adhesive part 151 formed on the back surface layer 13 side of the wing part 15. The shape of the sheet 50 is not limited to the example described in the above embodiment. For example, in the sanitary napkin package 1 in the unfolded state, the release sheet 50 is disposed on the back layer 13 side of the napkin 10 so as to cover the wing adhesive portion 151 in a state where the release sheet 50 and the separator 30 are adhered. In addition, when the sanitary napkin package 1 is folded, the release sheet 50 may be folded inside the napkin 10 integrally with the wings 15.

Alternatively, the release sheet 50 and the separator 30 may be formed as one component, and the adhesive part 131 and the wing part adhesive part 151 may be protected together by the separator 30.

<About the concentration of perfume>
In the above-described embodiment, the fragrance portion 25 is formed by attaching a fragrance to a predetermined region on the packaging surface 21 side of the packaging sheet 20, but the amount of the fragrance attached per unit area of the packaging surface 21 is determined. You may change for every area | region. That is, the fragrance | flavor density | concentration may differ so that it may differ for every area | region in the scent part 25. For example, in the packaging sheet 20, the amount of perfume attached per unit area increases in the inner side in the horizontal direction (that is, the concentration increases), and the amount of perfume adheres per unit area decreases in the outer side in the horizontal direction (ie, the concentration decreases). The perfume part 25 is formed so that it may become low. In this way, in a state where the sanitary napkin package 1 is folded, the position of the fragrance becomes lower as the position is closer to the outside of the sanitary napkin package 1, and the position far from the outside of the sanitary napkin package 1 ( That is, since the concentration of the fragrance increases toward the inside), the fragrance is less likely to leak to the outside, and it is easy to suppress the fragrance from moving to the candy.

Further, in the state in which the sanitary napkin package 1 is folded, the concentration of the fragrance may be set higher in the region on the inner side in the thickness direction. In other words, the amount of perfume per unit area that adheres to the packaging sheet 20 may be greater on the inner side in the thickness direction than on the outer side in the thickness direction. For example, as described in FIG. 12, in the region between F3 and 20eb, a large number of members (napkin 10, separator 30, and packaging sheet 20) overlap in the thickness direction. There is a low possibility that the scent leaks to the outside in the scented portion 25E. Therefore, it is preferable to form the scented portion 25 so that the concentration of the fragrance increases in the inner region in the thickness direction.

In particular, if the method of ejecting perfume ink using an ink jet printer as in the present embodiment, it is possible to change the density for each nozzle that ejects perfume ink when the perfume portion 25 is formed. Therefore, a fragrance | flavor can be made to adhere by the predetermined density | concentration to the packaging sheet 20 predetermined area | region. Therefore, it is possible to easily adjust the concentration of the fragrance when the fragrance portion 25 is formed.
