However, the absorbent article of Patent Document 1 can increase the aroma emitted from the absorber, but tends to weaken the aroma emitted from other than the absorber. Further, in the absorbent article of Patent Document 2, in the state in which the release sheet is peeled off, the aroma emitted from the area facing the release sheet can be increased, but the aroma emitted from areas other than the area tends to be weakened. Similarly, in the absorbent article of Patent Document 3, in the state where the individual wrapping sheet is peeled off, the fragrance emitted from the area facing the individual wrapping sheet can be increased, but the fragrance emitted from other areas is likely to be weakened. That is, in the absorbent articles of Patent Documents 1 to 3, there were regions where the fragrance was strongly emitted and regions where the fragrance was weakly emitted, and there was unevenness in the fragrance.

Therefore, the package of the absorptive article which suppresses the unevenness of the aroma in the absorptive article and can release the aroma uniformly as the whole absorptive article is provided.

An absorbent article package according to one aspect includes an absorbent article having an absorbent core, a packaging bag that houses the absorbent article, and a scent member that has a fragrance and emits a fragrance. The absorbent article is housed in the packaging bag together with the scent member, and is arranged so as to be movable relative to the scent member.

It is a perspective view of the package of the absorptive article concerning an embodiment. It is sectional drawing along the AA cross section of the package of an absorbent article. It is a development top view of an absorptive article. It is sectional drawing which followed the BB cross section of an absorbent article. It is the figure which showed the scent member which concerns on embodiment.

(1) Outline of Embodiments At least the following matters will be made clear by the present specification and the description of the accompanying drawings.
An absorbent article package according to one aspect includes an absorbent article having an absorbent core, a packaging bag that houses the absorbent article, and a scent member that has a fragrance and emits a fragrance. The absorbent article is housed in the packaging bag together with the scent member, and is arranged so as to be movable relative to the scent member.

The scent member and the absorbent article are arranged in the packaging bag, and the aroma emitted from the scent member perfumes the absorbent article. The absorbent article is configured to be relatively movable with respect to the scent member, and is unlikely to be locally scented by the scent member as compared with a form in which the absorbent article and the scent member are integrated. The same degree of perfume can be easily applied to the entire absorbent article, and unevenness in aroma can be suppressed.

According to a preferred aspect, the scent member may be arranged so as to be movable relative to the inner surface of the packaging bag.

According to this aspect, the scent member is movable in the packaging bag, and when the package vibrates during distribution of the absorbent article, the scent member moves in the packaging bag and spreads over the entire absorbent article. The same level of fragrance can be applied and unevenness in aroma can be suppressed.

According to a preferred embodiment, the scent member has a fragrance main body having the fragrance, and a covering member for accommodating the fragrance main body, and the covering member has a hole for releasing the fragrance of the fragrance. It is formed, and the weight of the fragrance body may be 50% or less with respect to the weight of the entire scent member.

According to this aspect, since the fragrance of the fragrance main body is released through the covering member, the area for releasing the fragrance becomes wider and the absorbent article is locally scented as compared with the configuration including only the fragrance main body. It is difficult to be affected and unevenness of aroma can be suppressed. Further, since the weight of the fragrance body is 50% or less, it is possible to prevent the absorbent article from being overly fragrant.

According to a preferred embodiment, the scent member has a fragrance body containing the fragrance, the absorbent core has a superabsorbent polymer containing silver ions, the weight of the fragrance body is the high absorption. May be up to 5% by weight of the organic polymer.

According to this aspect, since the weight of the fragrance body is 5% or less of the weight of the superabsorbent polymer, it is difficult to inhibit the deodorizing function. Therefore, the aroma can be imparted while exhibiting the deodorizing function of the silver ion of the superabsorbent polymer.

According to a preferred aspect, the scent member has a fragrance body having the fragrance, and the absorbent article has a hot-melt adhesive that bonds the constituent members of the absorbent article. The weight of the fragrance body may be 50% or less with respect to the weight of the hot melt adhesive.

According to this aspect, the components of the hot melt adhesive may be modified depending on the components of the fragrance. However, since the weight of the fragrance is 50% or less of the weight of the superabsorbent polymer, it is possible to prevent the fragrance from modifying the components of the hot melt adhesive and protect the hot melt adhesive.

According to a preferred embodiment, the absorbent article has a non-skin surface sheet that constitutes a non-skin surface of the absorbent article, and the non-skin surface sheet has a nonwoven fabric having a basis weight of 8 g or more. Good.

According to this aspect, the non-skin surface sheet made of the non-woven fabric having a basis weight of 8 g or more is less likely to cause uneven texture and is easily perfume over the whole. In addition, the non-skin surface sheet made of a non-woven fabric is more fragrant than the non-skin surface sheet made of a film. Therefore, even if a scent member separate from the absorbent article is used, the aroma can be retained by the absorbent article.

According to a preferred aspect, a second non-skin sheet made of a film is provided on the skin side of the non-skin surface sheet and on the non-skin surface side of the absorbent core, and the absorbent article has a skin The non-skin surface sheet may be placed on the outer surface of the absorbent article in a folded state with the surface side facing inward, and in the folded state.

According to this aspect, the absorbent article is accommodated in the packaging bag in a folded state, and the non-skin surface sheet that constitutes the outer surface of the absorbent article is easily scented. At this time, the second non-skin surface sheet having the film is arranged between the non-skin surface sheet and the absorbent core, and since it is difficult for the fragrance to pass through the second non-skin surface sheet, the second non-skin surface sheet is placed outside the second non-skin surface sheet. The non-skin surface sheet located is easily fragrant. Since the non-skin surface sheet generally has a lower basis weight than the absorbent core, it is difficult to locally retain the aroma, and the aroma is easily retained as a whole.

According to a preferred aspect, the coefficient of friction of the outer surface of the scent member may be lower than the coefficient of friction of the non-skin surface sheet.

According to this aspect, the scent member is more likely to move in the packaging bag than the absorbent article, and the entire absorbent article contained in the packaging bag is easily scented by the scent member.

The absorbent article 10 has a front-back direction L and a width direction W that are orthogonal to each other. The front-rear direction L is defined by the direction extending to the front side of the body and the back side of the body. In other words, the front-back direction L is a direction extending in the front-back direction in the expanded absorbent article 10. Further, the absorbent article 10 has a thickness direction T orthogonal to both the front-rear direction L and the width direction W.

The absorbent article 10 has a front waistline region S1, a back waistline region S2, and a crotch region S3. The front waistline region S1 is a region facing the front waistline (abdomen) of the wearer. The rear waistline region S2 is a region facing the rear waistline (back part) of the wearer. The crotch region S3 is a region located at the crotch of the wearer and arranged between the front waistline region S1 and the rear waistline region S2. The crotch region S3 is a region in which the leg openings 18 are formed. The boundary of the front waistline region S1 on the crotch region side is the front end edge of the leg waist opening portion 18, and the boundary of the rear waistline region S2 on the crotch region side is the rear end edge of the leg waist opening portion 18.

In the present embodiment, the absorbent article 10 may include the exterior body 15 and the absorbent main body 11. The absorbent main body 11 and the outer package 15 may be joined by a hot melt adhesive. The exterior body 15 may overlap the absorbent main body 11 in the thickness direction and may be arranged on the non-skin surface side T2 of the absorbent main body 11.

The exterior body 15 may be formed of a sheet such as a non-woven fabric. A plurality of exterior sheets may be provided, and the exterior sheets may be joined together by a hot melt adhesive 30 (see FIG. 4). Among the exterior sheets, the exterior sheet located closest to the non-skin surface side T2 constitutes the non-skin surface sheet 16 that constitutes the non-skin surface of the absorbent article. The non-skin surface sheet 16 may be made of a nonwoven fabric having a basis weight of 8 g/m ³ or more. The absorbent article 10 is provided with a side joint portion 60 that joins an outer side portion of the front waistline region S1 in the width direction W of the exterior body 15 and an outer side portion of the rear waistline region S2 in the width direction W, and is a pant type. May be molded into. FIG. 3 shows a state in which the joining at the side joining portion 60 is released and the absorbent article 10 is expanded.

The inner portion in the present invention is a portion that occupies a certain range in the width direction W including the inner edge in the width direction W, and the inner edge is the inner edge in the width direction W. Further, the front end portion and the rear end portion in the present invention are portions that occupy a certain range in the front-rear direction L including the edges in the front-rear direction L, and the front end edge and the rear end edge are edges in the front-rear direction L. The outer end portion includes a front end portion and a rear end portion, and the outer end edge includes a front end edge and a rear end edge.

The absorbent main body 11 extends over the front waistline region S1, the rear waistline region S2, and the crotch region S3. The absorbent main body 11 may include the absorbent core 12 and the backsheet 14 located on the non-skin surface side T2 of the absorbent core 12. The absorbent core 12, the topsheet 13 and the backsheet 14 may be joined together by a hot melt adhesive 30. All the members constituting the absorbent article, such as the exterior sheet of the exterior body 15, the topsheet 13, the backsheet 14, and the absorbent core 12, which form the absorbent body 11, are the "components of the absorbent article" in the present invention. Make up.

The topsheet 13 is a liquid-permeable sheet and may be made of, for example, a nonwoven fabric. The back sheet 14 is a liquid-impermeable sheet, and may include, for example, a film. The back sheet 14 may be composed of only a film, or may be composed of a laminated sheet containing the film. The back sheet 14 is arranged on the skin surface side T1 of the non-skin surface sheet 16 and the non-skin surface side T2 of the absorbent core 12, and constitutes the “second non-skin surface sheet” of the present invention.

The absorbent core 12 may include, for example, ground pulp 12A or superabsorbent polymer (SAP) 12B, or a mixture thereof. The absorbent core 12 is arranged at least in the crotch region S3. Preferably, the absorbent core 12 may extend in the front-rear direction L from the front waistline region S1 to the rear waistline region S2. The absorbent core 12 may be covered by a core wrap. The superabsorbent polymer 12B may contain silver ions. Silver ions exert a deodorizing function.

FIG. 5 is a diagram showing the scent member 70. FIG. 5A is a plan view, and FIG. 5B is a C-C cross section shown in FIG. 5A. The scent member 70 has a fragrance and emits a fragrance. The scent member 70 only needs to be capable of releasing the scent, and its shape is not limited. Examples of fragrances include bergamot, orange, rosemary, lavender, basil, jasmine, tea, moss, musk, apple, blackcurrant, berry, rose, muguet, geranium, tuberose, leaf green, apricot seed, Cedar wood, vanilla, sandalwood may be exemplified.

The absorbent article 10 is housed in the packaging bag 20 together with the scent member 70, and is arranged so as to be movable relative to the scent member 70. Specifically, the absorbent article 10 and the scent member 70 may be configured to be movable in the packaging bag 20 without the absorbent article 10 and the scent member 70 being fixed to the inner surface 21 of the packaging bag 20. Moreover, in another embodiment, one of the absorbent article 10 and the scent member 70 may be fixed to the inner surface 21 of the packaging bag 20, and the other may not be fixed. According to another form, the absorbent article 10 or the scent member 70 moves in the packaging bag 20 so that the absorbent article can move with respect to the scent member.

The scent member 70 and the absorbent article 10 are arranged in the packaging bag 20, and the aroma emitted from the scent member 70 perfumes the absorbent article 10. The absorptive article 10 is configured to be movable relative to the scent member 70, and compared with the form in which the absorptive article 10 and the scent member 70 are integrated, the scent member 70 locally perfumes. Hard to be done. It becomes easy to perfume to the same degree all over the absorbent article 10, and unevenness in aroma can be suppressed.

Preferably, the scent member 70 may be arranged so as to be movable relative to the inner surface 21 of the packaging bag 20. The scent member 70 is movable in the packaging bag 20, and when the package 1 vibrates during distribution of the absorbent article 10, the scent member 70 moves in the packaging bag 20 to cover the entire absorbent article 10. Aroma can be imparted over the same range and unevenness in aroma can be suppressed. More preferably, the absorbent article 10 as well as the scent member 70 may be arranged so as to be movable relative to the inner surface 21 of the packaging bag 20. Since the scent member 70 and the absorbent article 10 move in the packaging bag 20, the positional relationship between the absorbent article 10 and the scent member 70 is likely to change, and the unevenness of aroma can be further suppressed.

The scent member 70 may include a fragrance body 71 having a fragrance and a covering member 72 that houses the fragrance body 71. The fragrance body 71 may be produced by mixing acrylic as a solvent and a fragrance. The fragrance body 71 may be in the form of particles such as spheres, and a plurality of the fragrance bodies 71 may be arranged in the covering member 72. The covering member 72 is made of, for example, a film, and may have a bag shape for accommodating the fragrance body, and may have a hole 73 for releasing the fragrance of the fragrance. A plurality of holes 73 may be arranged at intervals in a plan view. Since the fragrance of the fragrance main body 71 is released through the covering member 72, the area for releasing the fragrance is larger than that of the structure including only the fragrance main body 71, and the absorbent article 10 is less likely to be locally perfumed. The unevenness of aroma can be suppressed. The configuration of the scent member is not limited, and in another form, the scent member may be configured only by the fragrance body such as a sheet impregnated with the fragrance without a covering member.

The weight of the fragrance body 71 may be 50% or less of the weight of the scent member 70 as a whole. Since the weight of the fragrance body 71 is 50% or less, it is possible to prevent the absorbent article 10 from being overly fragrant. The weight of the fragrance body 71 may be 10% or more of the weight of the scent member 70 as a whole. Since the weight of the fragrance body 71 is 10% or more of the total weight of the scent member 70, even if the fragrance body 71 is covered with the covering member 72, the fragrance is easily released.

The weight of the fragrance body 71 may be 5% or less with respect to the weight of the superabsorbent polymer 12B. According to such a configuration, since the weight of the fragrance body 71 is 5% or less of the weight of the superabsorbent polymer 12B, it is difficult to inhibit the deodorizing function. Therefore, the aroma can be imparted while exhibiting the deodorizing function of the superabsorbent polymer 12B by the silver ions. Moreover, the weight of the fragrance|flavor main body 71 may be 0.1% or more with respect to the weight of the superabsorbent polymer 12B. When the weight of the fragrance main body 71 is 0.1% or more with respect to the weight of the superabsorbent polymer 12B, the scent can be sufficiently imparted to the absorbent article.

The weight of the fragrance body 71 may be 50% or less based on the weight of the hot melt adhesive 30. Depending on the components of the fragrance, the components of the hot melt adhesive 30 may be modified. However, since the weight of the fragrance is 50% or less of the weight of the superabsorbent polymer, it is possible to prevent the components of the hot melt adhesive 30 from being modified by the fragrance and protect the hot melt adhesive 30. The weight of the fragrance body 71 may be 10% or more of the weight of the hot melt adhesive 30. When the weight of the fragrance main body 71 is 10% or more with respect to the weight of the hot melt adhesive 30, sufficient fragrance can be imparted to the absorbent article.

The weight of the present invention can be measured in a natural state. Here, in the natural state, in the case of an absorbent article housed in a package, the absorbent article is taken out of the package and left in an atmosphere of 20° C.±2° C. and a relative humidity of 60%±5% RH for 24 hours. It has been left alone. Specifically, after measuring the weight of the fragrance member in a natural state, the covering member is opened, the fragrance body is taken out, and the weight of the fragrance body is measured. In addition, the weight of the superabsorbent polymer is determined by separating the superabsorbent polymer and the other portion (pulp) after removing the members (surface sheet, etc.) other than the absorbent core after developing the absorbent article. The absorbent polymer is measured. The hot melt adhesive measures the basis weight and area of the hot melt adhesive, and calculates based on the basis weight and area.

The non-skin surface sheet 16 of the absorbent article 10 may have a nonwoven fabric having a basis weight of 8 g or more. The non-skin surface sheet 16 made of a non-woven fabric having a basis weight of 8 g or more is less likely to cause unevenness in the formation, and is easily perfumed throughout. Further, the non-skin surface sheet 16 made of a non-woven fabric is more fragrant than the non-skin surface sheet made of a film. Therefore, even if the scent member 70 separate from the absorbent article 10 is used, the aroma can be retained by the absorbent article 10.

The absorbent article 10 may be stored in the packaging bag 20 in a folded state with the skin surface side T1 inside. The non-skin surface sheet 16 is disposed on the outer surface of the absorbent article in the folded state, and the back surface sheet that constitutes the second non-skin surface sheet is provided inside the non-skin surface sheet 16 (skin surface side). 14 may be arranged. The absorbent article 10 is accommodated in the packaging bag 20 in a folded state, and the non-skin surface sheet 16 forming the outer surface thereof is easily scented. At this time, the backsheet 14 having a film is disposed between the non-skin sheet 16 and the absorbent core 12, and since it is difficult for aroma to pass through the backsheet 14, the nonskin sheet 16 positioned outside the backsheet 14 Will be easily scented. Since the non-skin surface sheet 16 generally has a lower basis weight than the absorbent core 12, it is difficult to locally retain the aroma, and the aroma is easily retained as a whole.

The coefficient of friction of the outer surface of the scent member 70 may be lower than the coefficient of friction of the non-skin surface sheet 16. The scent member 70 is more likely to move than the absorbent article 10 in the packaging bag 20, and the entire scent member 70 contained in the packaging bag 20 is easily scented by the scent member 70. Preferably, the coefficient of friction of the inner surface 21 of the packaging bag 20 may be lower than the coefficient of friction of the outer surface of the scent member 70 and lower than the coefficient of friction of the non-skin surface sheet 16. The absorbent article 10 and the scent member 70 are more easily moved in the packaging bag 20, and the entire absorbent article 10 is easily aromatized.

The friction coefficient is measured by KES manufactured by Kato Tech Co., Ltd., which is generally known as a characteristic value representing the feel of the surface of a sheet (reference: standardization and analysis of texture evaluation (second edition)). , Author K. Kawabata, published on July 10, 1980). Specifically, KES-FB4 manufactured by Kato Tech Co., Ltd. was used as a sample in a range of 1.0×1.0 cm in each sample, and the sample was placed on a test bench having a smooth metal plane. The friction coefficient was measured by applying a force of 50 gf by a weight to a contact in which ten piano wires having a diameter of 0.5 mm were arranged, and the contact surface of the contact was pressed against the sample. The sample was moved horizontally by 2 cm at a speed of 0.1 cm/sec, and a uniaxial tension of 20 gf/cm was applied to the sample. Characteristic values were measured in each of two orthogonal directions in each sample, and the average thereof was obtained.

Although the present invention has been described in detail above using the above-described embodiments, it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented as modified and changed modes without departing from the spirit and scope of the present invention defined by the description of the claims. Therefore, the description of the present specification is for the purpose of exemplifying explanation, and does not have any restrictive meaning to the present invention.

It is possible to provide a package of absorbent articles capable of suppressing the unevenness of the aroma in the absorbent article and uniformly releasing the aroma as the entire absorbent article.
