Further, each of the pair of side sheets 5, 5 has an outer end in the width direction _DW joined to the skin-facing surface of the back sheet 3 to form a fixed end, and a fixed end in the width direction _DW . The center side end portion is not joined to any component such as the top sheet 2 and forms a free end portion. As a result, when the sanitary napkin 1 is worn, the center side end (free end) of the pair of side sheets 5, 5 in the width direction _DW stands up to prevent leakage of liquid excrement discharged from the wearer. A leak-proof wall part can be formed to prevent leakage.

The band-shaped sheet-like member used for the side sheet may be one that has various properties (for example, liquid impermeability (leakproofness), texture, flexibility, strength, etc.) that can be used as the side sheet of an absorbent article. There is no particular restriction, and for example, a liquid-impermeable sheet-like member similar to the above-mentioned back sheet (i.e., a sheet-like member such as a hydrophobic nonwoven fabric or a hydrophobic resin film) cut into strips may be used. can.

Further, in the present invention, the side sheet preferably has a light transmittance of 45% or more, more preferably 50% or more, and even more preferably 55% or more. If the side sheet has a light transmittance of 45% or more, even if the coloring source of the color corresponding to the function of the functional agent is located on the non-skin-facing side of the side sheet, the above color can be easily seen through the side seats. That is, when the folded absorbent article is unfolded, it is confirmed that the skin facing surface of the first surface corresponding portion corresponding to the first surface of the individual package exhibits a color corresponding to the function of the above-mentioned functional agent. , which can be more easily recognized.

In the present invention, the outer shape, various dimensions, basis weight, etc. of the side sheet can be any arbitrary outer shape, various dimensions, basis weight, etc. depending on the desired leakproofness, texture, flexibility, etc.

In addition, in the present invention, since it is not an essential component to include the pair of side sheets, the absorbent article may not necessarily have such side sheets depending on the form of the absorbent article.

The sheet-like member forming the functional member 21 includes a warming agent as a functional agent, a base material capable of holding the warming agent, and a color corresponding to the function (warming function) of the warming agent (i.e., Warm color) colorant.
In the present invention, the sheet-like member forming the functional member includes a liquid or solid (including paste, powder, etc.) functional agent and a structure capable of holding the functional agent. As long as it contains at least a base material, it does not need to contain a coloring agent of a color corresponding to the function of the functional agent. In that case, a coloring source of a color corresponding to the function of the functional agent is provided in another component (eg, back sheet, etc.).

The base material capable of retaining the above-mentioned functional agent is not particularly limited as long as it can retain a liquid or solid functional agent, such as fabric (e.g., non-woven fabric, woven fabric, knitted fabric, etc.) Examples include quality resin sheets (for example, sponge sheets, etc.). Such a base material does not need to be used alone as a base material for a functional component, but may also be used in combination with other constituent members (for example, a top sheet, a back sheet, an intermediate sheet, a core wrap sheet, etc.). Good too.
In addition, in the case where the functional agent itself has a predetermined shape retention property, etc., and can be placed at a predetermined position of an absorbent article by itself and exhibit a predetermined function, the functional member is It does not need to have a base material.

In addition, in the above-mentioned sanitary napkin 1, the warming agent used as the functional agent stimulates the thermal receptors of the wearer's skin without generating heat itself, and causes the wearer to perceive a warm sensation. It contains a sensitive ingredient.
In the above-mentioned sanitary napkin 1, the warming agent is contained in almost the entire functional member 21 in plan view, but if it can exhibit a predetermined warming function, the warming agent may be contained in a portion (for example, , only in the center, etc.).

In the sanitary napkin 1 described above, even if the functional member 21 is disposed on the side of the non-skin facing surface than the top sheet 2, the warming agent of the functional member 21 may be eluted or dissolved when the sanitary napkin 1 is worn. Because it can permeate the top sheet 2 due to volatilization and come into contact with the skin of the wearer's lower abdomen, the warming component of the warming agent stimulates the thermal receptors of the skin and can give a sense of warmth.
In this way, the wearer's lower abdomen, that is, the area close to the wearer's uterus, is heated, which alleviates the wearer's menstrual pain and symptoms such as premenstrual syndrome, sensitivity to cold, and menopausal symptoms. It is expected.

Note that the position in the thickness direction _DT at which the functional member 21 is arranged is not particularly limited as long as the warming agent can come into contact with the wearer's skin when wearing the sanitary napkin 1; In terms of ease of contact with the skin, the position is preferably close to the skin-facing surface _SF .

In the present invention, the content (basis weight) of the functional agent in the functional member can be a predetermined content depending on the type of the functional agent, the arrangement position of the functional member, and the like. For example, when a warming agent or a cooling agent is used as the functional agent and the functional member is arranged in the same form as the above-mentioned sanitary napkin 1, the functional agent may be a warming agent or a cooling agent. ^The basis weight of ^the warming-sensing ^component or cooling-sensing component contained in It can be contained in the functional member with such a basis weight.

In the sanitary napkin 1 described above, the functional member 21 is colored with a color corresponding to the warming function of the warming agent as a functional agent, that is, a warm coloring agent. As a result, the individual packaging body 10 formed by folding the sanitary napkin 1 has a warm color corresponding to the warming function of the warming agent, using the functional member 21 colored in a warm color as a coloring source. Since the color can be visually recognized by the user through the first surface _S1 of the individual packaging body 10, the user can easily recognize the thermal function of the sanitary napkin 1 even in the state of the individual packaging body. I can do it.
Further, the functional member 21 is formed by sandwiching air-laid pulp (white) between colored tissues in the thickness direction. In this way, the sheets forming the skin-facing surface side and the non-skin-facing surface side of the functional member 21 have a higher fiber density than airlaid, and pigments and the like can be easily diffused (that is, colors can be easily expressed). ) By using tissue, the color can be more easily recognized from both the top sheet and the back sheet than by simply coloring airlaid pulp (a material with low fiber density and excellent heat retention).
Alternatively, colored tissue may be sandwiched between sheets of air-laid pulp, nonwoven fabric, or the like to develop color. Thereby, the above color can be expressed without interfering with the placement of the functional agent or the absorption of liquid excreta.

Here, in this specification, "a color corresponding to the function of the functional agent" means a color that evokes the function of the functional agent. For example, if the functional agent is a warming agent or exothermic agent, a warm impression is given. Warm colors such as red, orange, and yellow that give a cold impression are applicable, and if the functional agent is a cooling agent, cool colors such as blue, blue-green, and blue-purple that give a cold impression are applicable. When the functional agent is a drug, neutral green colors such as green and yellow-green that give a good health or natural impression are applicable. Furthermore, if the functional agent is a deodorant or the like, black or gray, which is reminiscent of activated carbon or silver ions, corresponds to the color.

In addition, in the above-mentioned sanitary napkin 1, as shown in FIGS. 2 and 3, the warm color of the colored functional member 21 is not only visible from the non-skin facing side through the back sheet 3, but also The skin-facing surface S _F is visible from the skin-facing surface side through the top sheet 2 and corresponds to the first surface S ₁ of the individual package 10 formed by folding the sanitary napkin 1 (i.e., the first surface-corresponding portion). and the non-skin facing surface _SB each exhibit a warm color corresponding to the function of the warming agent. As a result, the individual packaging body 10 formed by folding the sanitary napkin 1 can be used not only in the state of the individual packaging body before use, but also when the user opens the individual packaging body 10 (i.e., the state of the folded sanitary napkin). When the napkin 1 is unfolded), the warming function of the sanitary napkin 1 can be easily recognized by visually recognizing the warm color.

In the present invention, the external shape, various dimensions, basis weight, etc. of the functional member may be any arbitrary external shape, various dimensions, basis weight, etc. depending on the type and arrangement form of the functional agent.

Further, the coloring agent used for coloring the functional member is not particularly limited, and any coloring agent (for example, pigment, dye, etc.) known in the art can be employed. Furthermore, the method of coloring with this colorant is not particularly limited, and the functional member may be colored by, for example, coating or printing the colorant, or the functional member may be colored by incorporating the colorant into the constituent components of the functional member. It may also be colored. The same applies when the coloring source of the color corresponding to the function of the functional agent is formed by a method other than coloring the functional member (for example, when directly coloring the first surface of the individual package).

[Adhesive part]
As shown in FIG. 3, the above-mentioned sanitary napkin 1 has a plurality of adhesive parts on the non-skin facing surface _SB of the back sheet 3, namely, the clothing fixing adhesive part 7 and the pair of flap part fixing adhesive parts 71, 71. , a pair of front-side first adhesive parts 72, 72 and a front-side second adhesive part 73, each of which is formed of an adhesive arranged in the above-described predetermined form.

As the adhesive used for such an adhesive part, any adhesive known in the art can be adopted, such as styrene-ethylene-butadiene-styrene (SEBS), styrene-butadiene-styrene (SBS), etc. and pressure-sensitive adhesives mainly based on styrene copolymers such as styrene-isoprene-styrene (SIS).

In the present invention, the arrangement, external shape, various dimensions, etc. of the various adhesive parts may be any arbitrary arrangement, external shape, various dimensions, etc. that take into account ease of fixing to clothing.

In addition, in the present invention, since it is not an essential component to include the adhesive portion, such an adhesive portion may not necessarily be provided depending on the form of the absorbent article.

In the individual package 10 described above, the packaging material 11 has a light transmittance of 45% or more and has a release-treated region on the surface facing the sanitary napkin 1. As a result, the individual packaging body 10 can easily see through the opposite side of the packaging material 11, and there is no need to separately provide a release sheet to protect the adhesive part of the sanitary napkin 1, so the configuration of the individual packaging body The number of members can be reduced, and the color corresponding to the function of the functional agent in the individual packaging body 10 can be more easily recognized through the packaging material 11.

In addition, in the present invention, when a coloring source of a color corresponding to the function of the functional agent is also arranged on the non-skin facing surface of the packaging material (for example, when the non-skin facing surface of the packaging material is colored), , the packaging material does not have to meet the above light transmittance requirements.
However, as in the above-mentioned embodiment, when the part exhibiting a color corresponding to the function of the functional agent is covered by the packaging material, it is preferable that the packaging material has a light transmittance of 45% or more, and 50% or more. % or more, and even more preferably 55% or more. When the light transmittance of the packaging material is 45% or more, the color corresponding to the function of the functional agent in the individual packaging becomes easier to recognize through the packaging material.

The sheet-like member that can be used as the packaging material is not particularly limited, and for example, a resin sheet, a nonwoven fabric, or the like can be used. Among these, from the viewpoint of airtightness of the individual package, it is preferable to use a resin sheet, and it is more preferable to use a resin sheet made of a polyolefin resin such as polyethylene or polypropylene. Such a resin sheet may have a single layer structure or a laminated structure of multiple layers, and may further have a barrier layer formed of ethylene vinyl alcohol copolymer (EVOH) resin or the like. .

In the present invention, the external shape, various dimensions, basis weight, etc. of the packaging material may be any arbitrary external shape, various dimensions, basis weight, etc. that take into account ease of packaging, airtightness, etc.

In addition, in the present invention, since it is not an essential component to include such a packaging material, when forming an individual package only with absorbent articles, the individual package may not include such a packaging material. You don't have to.

A lead tape 12 is provided. The lead tape 12 seals the open end of the packaging material 11 folded together with the sanitary napkin 1 to maintain the individually wrapped state of the folded sanitary napkin 1, and is formed of a band-shaped tape member. has been done.

The tape member used as the lead tape can be any tape member known in the art. For example, a strip-shaped tape base material (e.g., film, nonwoven fabric, paper, etc.) and a surface of the tape base material can be used as the lead tape. Examples include those configured with an adhesive (for example, a rubber adhesive, an acrylic adhesive, etc.) disposed on the surface of the adhesive. Furthermore, the constituent materials of the film or nonwoven fabric that can be used as the tape base material are not particularly limited, and include, for example, polyolefin resins such as polyethylene and polypropylene; polyester resins such as polyethylene terephthalate; polyamide resins; polyurethane resins, etc. Can be mentioned. Such tape base material may have elasticity.

In the above embodiment, the lead tape 12 of the individual package 10 corresponds in the thickness direction to the first surface _S1 of the outer surface of the packaging material 11, as shown in FIG. 1(a). placed in the parts. In this way, if the lead tape 12 that is easily noticed by the user is placed on the part of the outer surface of the packaging material 11 that corresponds to the first surface _S1 in the thickness direction, the user can easily see the lead tape 12. When peeling off the tape 12 and opening the individual package 10, the color of the first surface S1 under the lead tape ₁₂ (i.e., the color corresponding to the function of the functional agent) can be recognized more reliably. can.

In the present invention, the arrangement form, external shape, various dimensions, etc. of the lead tape may be any arrangement form, external shape, various dimensions, etc. that take into consideration the strength required for the lead tape, ease of opening, etc. can.

In addition, in the present invention, it is not an essential component to have such a lead tape, so if the individual packaging state can be maintained by means other than the lead tape (for example, heat-sealing means, etc.), individual packaging may be used. The body does not have to be equipped with such lead tape.

[Method for forming individual packages]
Hereinafter, a method for folding an absorbent article (ie, a method for forming an individual package) for forming an individual package of the present invention will be described in detail with reference to the drawings.

The individual packaging body 10 of the above-described embodiment stores the sanitary napkin 1 in the unfolded state as shown in _FIG . After folding into three in the width direction _DW so that the skin-facing surface S _F is on the inside on each of the fold line LW ₁ and the second longitudinal fold line LW ₂ , As shown, in each of the first widthwise folding line _LL1 and the second widthwise folding line _LL2 extending in the widthwise direction _DW , it is folded into three in the longitudinal direction _DL so that the skin-facing surface _SF is on the inside. Can be formed by folding.

In addition, when folding the sanitary napkin 1, the sanitary napkin 1 is folded together with the packaging material 11 attached to the non-skin facing surface _SB , and further, after folding, the packaging material 11 is folded on the outer surface of the packaging material 11. The open end of the folded packaging material 11 is sealed by the lead tape 12 placed at the end of the packaging material 11 to maintain the packaged state.

In the present invention, the method for folding the absorbent article to form individual packages is not limited to the above-described embodiments, but may be any method that takes into consideration the compactness of the individual packages, ease of opening, etc. folding method can be adopted.
(Another embodiment)

Furthermore, in the present invention, the absorbent article that can be used as an individual package is not limited to the aspects of the above-described embodiments, and in particular, the arrangement form of the functional agent (that is, the arrangement form of the functional member) can be changed as appropriate. It is possible.
Hereinafter, with reference to the drawings, an absorbent article (sanitary napkin 1A) according to another embodiment of the present invention, which differs from the sanitary napkin 1 according to the above-described embodiment only in the arrangement of functional members and absorbent bodies, will be described. Explain in detail. In addition, since the structure other than the structure different from the above-mentioned sanitary napkin 1 is basically the same as that of the above-mentioned sanitary napkin 1, the description is omitted.

As shown in FIGS. 6 and 7, a sanitary napkin 1A according to another embodiment of the present invention has a functional member 21A and an absorbent body 4A each having a short length in the longitudinal direction D _L. 21A and the absorber 4A are arranged so as not to overlap in the thickness direction _DT . That is, the sanitary napkin 1A does not have the overlapping part 40 like the sanitary napkin 1 described above.

The sanitary napkin 1A has folds formed when the sanitary napkin 1A is folded (particularly along the first fold line LL ₁ in the width direction in FIG. 6) on the skin-facing surface _SF in the unfolded state. Furthermore, on both sides of the crease, there is a region exhibiting a warm color corresponding to the function of the warming agent (i.e., in FIG. 6, a first fold line LL in the width direction). A functional area 20A which is located on the front side D _F with ₁ as a boundary and where the warm color of the functional member 21A can be visually recognized, and an area exhibiting other colors (i.e., in FIG. 6, the first fold in the width direction). The absorbent region 30A) is located on the rear side _DB with the line _LL1 as a boundary. Note that this "area exhibiting other colors" is not particularly colored and usually exhibits a white color.
As a result, in the individual package formed by folding the sanitary napkin 1A, the boundaries between the above-mentioned regions are easily recognized by the folds, so when the user unfolds the folded sanitary napkin 1A, the above-mentioned Warm colors corresponding to the function of the warming agent can be more clearly recognized.
Furthermore, this individual package has a warm color area corresponding to the function of the warming agent, which has a larger area in plan view than areas showing other colors, so it cannot be used. When a person unfolds the folded sanitary napkin 1A, the person can more clearly and reliably recognize the warm color corresponding to the function of the warming agent.

Furthermore, in the sanitary napkin 1A, the functional member 21A has a smaller thickness than the absorbent body 4A of the absorbent region 30A, as shown in FIG. Therefore, in the unfolded state of the sanitary napkin 1A, the thickness of the portion including the functional member 21A (i.e., the first surface corresponding portion) is different from the thickness of the portion adjacent to the portion (more Specifically, the thickness of the portion including the functional member 21A is smaller than the thickness of the portion adjacent to the portion).
In this way, if the thickness of the first surface corresponding part of the sanitary napkin 1A is different from the thickness of the part adjacent to the first surface corresponding part, the boundary between these parts will be different from the three-dimensional visual perception based on the thickness difference. The differences in texture and texture make it easier to see, so when the user unfolds the folded sanitary napkin 1A, the user can more clearly recognize the warm color corresponding to the function of the warming agent. can. In addition, when the sanitary napkin 1A has such a difference in thickness, there is an advantage that the folded sanitary napkin 1A can be easily unfolded due to the difference in rigidity.

The absorbent article in the individual package of the present invention is not limited to the sanitary napkins of the above-mentioned embodiments, but can be applied to various absorbent articles such as panty liners, incontinence pads, breast pads, and disposable diapers. .
Furthermore, the individual packages of the present invention are not limited to the above-described embodiments, and can be combined, substituted, and changed as appropriate within the scope of the purpose and gist of the present invention. In addition, in this specification, ordinal numbers such as "first" and "second" are used to distinguish the items to which the ordinal numbers are attached, and do not mean the order, priority, importance, etc. of each item. It's not something you do.
