Detailed Description of the Invention

TECHNICAL FIELD The present invention relates to an individual package of an absorbent article having a mechanism for suppressing the rupture of a packaging material, even when volatile components volatilize from the absorbent article.

In the individual packages of the conventional absorbent articles, volatile components are more easily volatilized at room temperature as fragrant substances are present, and may become less effective before use, or may transfer odors to adjacent materials. From the viewpoint of preventing such loss of the active ingredient and maintaining hygiene, as described in Patent Documents 1 to 3, packaging materials having high gas barrier properties may be used.
However, if a packaging material having high gas barrier properties is used, the individual packaging may be expanded by the volatilization of the active ingredient, and the packaging material may be ruptured, in which case the active ingredient disappears and the hygiene condition is maintained. It disappears. In particular, when carrying an individual package, it may be difficult to maintain the active ingredient and the hygienic condition by the above-mentioned mechanism because pressure is applied by putting it in a pouch or the like. Since individual packaging is premised on such a use form, prevention of rupture of the packaging material is strongly desired.

In the individual package of the absorbent article of the present invention, even if the volatile component volatilizes from the absorbent article, it can be gradually removed from the individual package, and the burst of the packaging material can be suppressed.

A preferred embodiment of an individual wrapping of an absorbent article according to the present invention will be described below with reference to the drawings.

In the present invention, the absorbent article refers to an article fixed to clothing such as underwear and worn on the body of a wearer to absorb and hold excrement and the like. For example, a sanitary napkin, a panty liner (cradle sheet) and the like can be mentioned.
The absorbent article has a side facing the wearer (skin) and a side facing the garment. The side facing the wearer is also referred to as the skin surface side, the skin contact surface side or the front surface side, and the side facing the clothing on the opposite side is the non-skin surface side, the non-skin contact surface side or the back surface side Say. In addition, the absorbent article has a longitudinal shape in a state in which the individual package is unfolded and deployed, and has a front part, a middle part and a rear part corresponding to the abdomen, crotch and back of the wearer. In this shape, it has a longitudinal direction corresponding to a direction connecting the belly side, the crotch and the dorsal side of the wearer, and a width direction perpendicular to the longitudinal direction. Similarly, the packaging material has a longitudinal direction and a width direction in a state where the individual packaging is unfolded and developed.
In an individual package, the longitudinal direction in the absorbent article and the packaging material corresponds to the direction in which the absorbent article and the packaging material are folded. Therefore, in the individual package, the longitudinal direction means the longitudinal direction of the absorbent article and the packaging material, and also means the direction in which the absorbent article and the packaging material are folded.

Hereinafter, the individual wrapping body of the present embodiment will be described as the individual wrapping body 30 of the sanitary napkin 10 (hereinafter, also simply referred to as the napkin 10). In the embodiment, the front part, the middle part and the rear part described above are denoted by the symbols F, C and R, and the longitudinal direction and the width direction are also referred to as the Y direction and the X direction.

As shown in FIGS. 1 and 2, in the individual wrapping body 30 of the present embodiment, both of the sanitary napkin 10 and the wrapping material 20 are two or more fold lines in the longitudinal direction (Y direction) of the sanitary napkin 10. Will be folded along. Specifically, in the sanitary napkin 10 and the packaging material 20, the portion including the middle portion C in the longitudinal direction of the sanitary napkin 10 is used as the folding central portion 31 and is folded along the folding lines L1 and L2 before and after that. There is.

In the present embodiment, the portions of the sanitary napkin 10 and the packaging material 20 before and after the folding central portion 31 are referred to as a first folding end 32 and a second folding end 33, respectively. Further, the continuous packaging material 20 is aligned with the division of the folding center portion 31, the first folding end portion 32, and the second folding end portion 33, and the central packaging portion 21, the first folding packaging portion 22, the second folding packaging portion 23 It is said.

The individual wrapping body 30 has a folding structure that wraps the skin contact surface 10A of the napkin 10. Specifically, with the packaging material 20 covering the surface 10B of the napkin 10 facing the garment, the first fold end 32 is folded with the skin contact surface 10A of the napkin 10 facing inward, and then the upper side 2Folding end 33 is folded up. The skin contact surface 10A of the napkin 10 is wrapped without being exposed. Here, in the thickness direction (Z direction) of the individual package 30, the side to be opened is referred to as the upper side Z1 and the side opposite to the side to be opened is referred to as the lower side Z2 in consideration of the state at the time of opening. The upper side Z1 and the lower side Z2 show the relative positional relationship in the thickness direction of the folded structure of the individual package 30.

The length in the longitudinal direction (Y direction) of the napkin 10 in the central folding portion 31 is longer than the length in the longitudinal direction of the napkin 10 in the first and

second folding portions

32 and 33. The individual wrapping body 30 in this case has a portion where the first folding end 32 and the second folding end 33 overlap and a portion which does not overlap on the upper side Z1 of the folding central portion 31. That is, it has a folded three-layer structure and a two-layer structure. The outer surface of the individual package 30 corresponds to the outer surface 51 corresponding to the folding center portion 31, the outer surface 52 corresponding to the portion where the first folding end 32 does not overlap the second folding end 33, and the second folding end 33 It has an outer surface 53. However, in the individual wrapping body 30, the length by which the napkin 10 is folded is not limited to this, and can be set variously.

The number of times of folding (the number of folding lines) and the position of the folding lines in the individual wrapping body 30 are not limited to the above embodiment, and can be set as appropriate. For example, depending on the length of the napkin 10, the number of times of folding and the position of the folding line are set so as to be a folding structure that wraps the skin contact surface 10A. Basically, for the laminate of the napkin 10 and the packaging material 20, it is preferable to set the number of times of folding and the position of the folding line so that the middle part C of the napkin 10 becomes the folding center part 31. For example, in the case where the back portion R is elongated, such as a night napkin, the back portion R can be folded in two and folded in four in total.

Moreover, although the packaging material 20 is shown as a thing longer than the napkin 10 in this embodiment, not only this but a thing shorter than the napkin 10 may be used. It is preferable that the wrapping material 20 be disposed beyond the end of the napkin 10 at the upper second folded end 33 to be finally folded, even if it is short. In this case, at the lower first folding end 32, the packaging material 20 is insufficient for the length of the napkin 10, and a partially uncovered part is generated. Therefore, "covering" the surface 10B of the packaging material 20 facing the garment 10 of the napkin 10 is not limited to covering the entire surface 10B of the napkin 10 facing the garment, but includes covering a part of the surface 10B. .

Here, the outline of the packaging material 20 and the pumpkin 10 will be described.

As shown in FIG. 3, the packaging material 20 is a member having a fusion layer 24 and an airtight layer 25 and having high airtightness. The fusion layer 24 is made of a fusion resin component and has a melting point lower than that of the hermetic layer 25. The adhesive layer 24 and the airtight layer 25 can prevent interface peeling of each other by arranging an adhesive layer therebetween. The hermetic layer 25 has high gas barrier properties, and the oxygen permeability is suppressed lower than that of the fusion layer 24. The oxygen permeability can be measured based on the coulomethylic method or the differential pressure method. The oxygen permeability as measured by the differential pressure method is preferably 900 mL / m ² · day atm or less, more preferably 100 mL / m ² · day atm or less, and 50 mL / m ² · day · atm under a 23 ° C. environment. The following is more preferable.
In the present embodiment, the packaging material 20 is composed of three layers in which both sides of the airtight layer 25 are covered with the fusion layer 24. However, the present invention is not limited to this, and two layers of the fusion layer 24 and the airtight layer 25 may be used, and another lamination mode may be provided. In any case, the fusion layer 24 of the packaging material 20 is disposed corresponding to the surface 10B of the napkin 10 facing the garment.

As shown in FIG. 4, the napkin 10 has a top sheet 1 on the skin contact surface side facing the wearer, a back sheet 2 on the non-skin contact surface side facing the clothing, and liquid retention between the two sheets. The absorber 3 is provided. The top sheet 1 has a liquid-permeability that sends the excrement fluid to the absorber 3, and the back sheet 2 has a leakproof property to the excrement fluid. The top sheet 1 and the back sheet 2 have a size that extends outward of the outer edge of the absorber 3 while covering both surfaces of the absorber 3. Furthermore, on both sides of the skin contact surface side of the top sheet 1, side sheets 5 for preventing lateral leakage of the excrement fluid are laminated.

The napkin 10 shown in FIG. 4 has a shape in which the front part F, the middle part C and the rear part R are divided into three equal parts and set for daytime and the like. The individual wrapping body 30 is not limited to this. For example, for night use, it may have a wide rear flap covering the buttocks, and the rear part R may be longer than the front part F and the middle part C.

The napkin 10 may have other members in addition to the above configuration. For example, a liquid diffusive intermediate sheet may be disposed between the top sheet 1 and the absorber 3. In addition, at the position of the middle portion C, a pair of wing portions may be provided as one of fixing means to the clothes or the like. The wing may be formed by the side sheet. Furthermore, it may have a leak-proof groove squeezed from the top sheet 1 to the absorber 3, a plurality of embossments on the top sheet 1, and the like.

The napkin 10 contains volatile components such as a fragrance and a cooling agent. The position to contain can be suitably set by the use etc. However, it is preferable that the volatile component is contained in the absorber 3 from the viewpoint of sufficiently exerting the effect at the time of use without diffusing to the outside as much as possible before the use. It is preferable that at least the application part of liquid volatile component or volatile component-containing liquid (sometimes simply referred to as “application part of volatile component”) be in the absorber. Moreover, it is more preferable that the application part of a volatile component is in the position which does not overlap with the below-mentioned mutually separable fastening parts 8 in the thickness direction of the napkin 10.

The volatile component-containing liquid is a coating liquid in which a volatile component and a solvent are mixed. As the solvent, various ones commonly used can be adopted. For example, dipropylene glycol, polypropylene glycol, triethyl citrate, benzyl benzoate and the like can be mentioned. The application part of the volatile component is a part initially contained in the manufacturing process of the napkin 10. Therefore, the application part of the volatile component is a part where the volatile component is the largest in the napkin 10 (a part where the contained basis weight is the largest).

The napkin 10 has a plurality of fastening portions 8 for fixing the napkin 10 to clothes, on the non-skin surface side of the back sheet 2 and on the surface 10B side facing the clothing. The fastening portion 8 is a means for securing to a garment when using the napkin 10, and is peelable and has an adhesive force to prevent the napkin 10 and the garment from shifting.
A plurality of fastening portions 8 are arranged apart from each other on the non-skin surface side of the back sheet 2. In the surface 10B facing the clothing, a plurality of portions where the fastening portion 8 is not disposed are disposed as a plurality of fastening portion non-arranged portions 9. The preferable arrangement of the fastening portion 8 and the fastening portion non-arranged portion 9 will be described later.

The napkin 10 and the packaging material 20 are folded along the folding lines L1 and L2 with the top sheet 1 side inside (folded in the order of arrows S1 and S2 shown in FIG. 4), and the individual packaging described above It is a body 30.

Next, the fused and sealed area 34 in the individual package 30 and the sealed and fixed area 36 in the opening 35 will be described with reference to FIGS. 1 and 2.

The individual wrapping body 30 has a pair of fusion sealing regions 34 formed by joining the folded wrapping material 20 on both sides outward (in the width direction (X direction) end portion outward) of the napkin 10 in the longitudinal direction. . The fusion seal area 34 is a part in which two sheets of the packaging material 20 are laminated and a part in which the three sheets are laminated, in accordance with the number of overlapping of the folding central portion 31, the first folding end 32 and the second folding end 33. And.
In the fusion seal area 34, the fusion layers 24 of the folded packaging material 20 face each other and are fusion-bonded regardless of the number of overlapping of the packaging materials 20. Thereby, the bonding strength of the welded portion is enhanced as compared with the case of bonding by the adhesive. However, the bonding strength of the fusion seal area 34 is such that it can be peeled off by the force applied when the individual package 30 is opened.

The fusion bonding of the fusion layers 24 of the packaging material 20 in the fusion seal area 34 can be performed by various methods commonly used. For example, a heat embossing process, an ultrasonic embossing process, a corona treatment, a plasma process etc. are mentioned. Above all, when fusion bonding is performed by heat embossing, the peel strength and air tightness can be adjusted to the desired range by adjusting the emboss shape and size, and further by performing corona treatment or plasma treatment Adhesiveness of the bonding joint can be enhanced, which is preferable.

The individual package 30 has an opening 35 at the overlapping portion of the first and second

folding end portions

32 and 33. The opening portion 35 has an extension portion 23A of the second fold packaging portion 23 which is longer than the napkin 10 at the second fold end portion 33 located on the upper side, and a first fold packaging portion of the lower first fold end portion 32. 22 is a portion to be stacked.
In the opening port 35, the sealing and fixing area 36 is disposed along the width direction (X direction) of the packaging material 20. The sealing and fixing area 36 overlaps the pair of

fusion sealing areas

34 and 34 located on the opposite side edges of the individual package 30 in a plan view, and extends inward in the width direction. In the sealing and fixing area 36, in the thickness direction of the individual wrapping body 30, the extending portion 23A of the second folding and wrapping portion 23 and the lower first folding and wrapping portion 22 can be peeled off by the force at the time of opening. It is joined. This bonding can be performed by various methods. As in the fusion seal area 34, bonding may be by heat melting or bonding by an adhesive.

An opening tab tape 37 is disposed in the packaging material 20 near the opening 35. The opening tab tape 37 may be optionally disposed, or may be absent. From the viewpoint of enhancing the openability, it is preferable to have the opening tab tape 37. Further, instead of the opening tab tape 37, a projection (picking portion) may be provided on a part of the packaging material 20 corresponding to the opening 35.

In the individual package 30, the volatile components contained in the napkin 10 are prevented from leaking out by the

fusion seal areas

34, 34 and the seal fixing area 36 of the packaging material 20. Further, the airtightness is enhanced by the airtight layer 25 of the packaging material 20.

On the other hand, the individual wrapping body 30 of the present embodiment is provided with a mechanism in which even if the volatile component contained in the napkin 10 volatilizes, it is gradually removed and the wrapping material does not burst. This mechanism is realized by the following structure.

The individual package 30 has a structure for exhausting volatile gas of volatile components generated inside. The said structure is provided between the packaging material 20 and the back surface sheet 2 (surface 10B facing clothing) side of the napkin 10 in the

outer surface

outer surfaces

52 and 53, and the fastening portion A non-arranged portion 91 and a fastening portion non-arranged portion 92 are arranged. The fastening portion 8, the fastening portion non-arranged portion 91 and the fastening portion non-arranged portion 92 are covered with the packaging material 20 in any of the

outer surfaces

51, 52 and 53.
The fastening portion 8 is releasably joined to the packaging material 20, and the fastening portion non-arranged portion 91 and the fastening portion non-arranged portion 92 are not joined to the packaging material 20, and a space is formed between both members. ing. That is, in the region 85 in which the fastening portion 8 is disposed, the ventilation path 911 extending in the width direction along the fastening portion non-arranging portion 91 extending in the width direction of the fastening portion non-arranging portion 9 in the longitudinal direction It occurs intermittently. Also, a longitudinally extending air passage 921 is connected to the fusion seal area 34 corresponding to the portion of the fastening portion non-arranged portion 92 outward in the width direction of the region 85 where the fastening portion 8 is disposed, A pair 921 is generated.

The

air passages

911 and 921 are located in the region where the volatile gas of the volatile component is easily collected in the individual package 30, and serve as a passage for the volatile gas.

In the first embodiment, the individual package 30 has the following structure (A1) of exhausting volatile gas of volatile component using the air passage 911 of the fastening portion non-arranged portion 91 extending in the width direction.
A fusion seal area 34 is present at the end passing through the air passage 911 generated in the fastening portion non-arranged portion 91 and reaching the width direction end, and the fusion seal area 34 has a gas release part 341. The fastening portion non-arranged portion 91 and the degassing portion 341 are covered by the highly airtight packaging material 20 to form a continuous space, and a structure for guiding the volatile gas of the volatile component outward in the width direction The
Thus, a structure (A1) is formed in which the fastening portion non-arranged portion 91 extending in the width direction and the degassing portion 341 of the fusion seal region 34 communicate with each other in the width direction. The structure (A1) is disposed on the

In this structure (A1), the exhaust of the volatile component volatile gas outward in the width direction can generate, for example, a pressing force on the packaging material 20 as a driving force.
For example, the volatile component volatile gas that collects on the surface 10B of the napkin 10 facing the garment when a force that squeezes inward from the

outer surfaces

51, 52 and 53 of the individual package 30 is applied is not a fastening portion non-arrangement portion It is induced in the width direction along 91. The degassing portion 341 of the fusion seal region 34 is opened by the pressure of the volatilized gas to be induced, and the volatilized gas gradually escapes (arrows shown in FIGS. 5B and 5C). As a result, it is possible to suppress the burst without the volatilization gas of the volatile component being accumulated in the individual package 30 too much.

From the viewpoint of gradually improving the exhaustability, it is preferable that a plurality of rows of fused portions 342 aligned in the longitudinal direction of the napkin 10 be arranged in the width direction. The degassing part 341 has a predetermined length along the line of the fusion part 342 aligned in the width direction, and the discharge amount of the volatile gas can be suitably controlled. In this case, in each row of fused portions 342 aligned in the longitudinal direction, the rows of fused portions 342 may be arranged at the same pitch (FIG. 6A) or may be arrayed at a different pitch ((6) FIG. 6 (B). In the case of different pitches, the pitch is appropriately set so that the gas removal amount can be suitably controlled while holding the communication mechanism.

Is preferred. As a result, while temporarily storing volatile gas from the ventilation passage 911 extending in the width direction in the fastening portion non-arranged portion 91, it is possible to disperse it in the longitudinal direction and exhaust it evenly in the entire fusion seal area 34. . As a result, the fusion seal area 34 is less likely to be subjected to excessive pressure, and more efficiently, it is possible to suppress bursting and gradually exhaust the volatile gas.

Furthermore, from the viewpoint of more suitably controlling the gas escape amount, the interval (H1) of the gas venting portion 341 disposed in the fusion seal area 34 is smaller than the distance (H2) between the

It is arranged. Thus, the volatile gas can be moved along the folding direction of the individual package 30 (FIGS. 7B and 7C).

In the second embodiment, the individual package 30 has the following structure (A2) for exhausting volatile gas of volatile component by utilizing the air passage 931 of the non-arranged portion 93 extending in the longitudinal direction.
That is, there is a sealing and fixing area 36 at the end which passes through the air passage 931 generated in the fastening part non-arranged part 93 and reaches the opening port 35 of the second folding end 33 in the longitudinal direction. 36 has the degassing part 361 (FIG. 7 (C)). The fastening portion non-placement portion 93 and the degassing portion 361 are covered by the highly airtight packaging material 20 to form a continuous space, and a structure for guiding the volatile gas from the sealing and fixing area 36 in the longitudinal direction outward. The
Thus, a structure (A2) is formed in which the fastening portion non-arranged portion 93 extending in the longitudinal direction and the degassing portion 361 of the sealing and fixing area 36 communicate in the longitudinal direction. The structure (A2) is disposed from the outer surface 52 of the first folding end 32 through the outer surface 51 of the folding center 31 to the outer surface 53 of the second folding end 33.

In the structure (A2), the degassing portion 361 in the sealing and fixing area 36 is a portion where the sealing and fixing area 36 extending in the width direction is not joined as shown in FIG. 7C. In more detail, it is a part by which the extension part 23A of the 2nd folding packaging part 23 and the lower 1st folding packaging part 22 are not joined.

In the structure (A2), the direction of flow of the volatile gas along the fastening portion non-arranged portion 93 and the direction of flow of the volatile gas along the degassing portion 361 from the viewpoint of better expressing the exhaust of the volatile gas by communication It is preferable that it is the same. Further, it is more preferable that the degassing portion 361 be present in the vicinity of the extension of the fastening portion non-arranged portion 93, and it is further preferable that the at least one degassing portion 361 be present on the extension of the fastening portion non-arrangement portion 93. . Specifically, as shown in FIG. 7C, it is preferable that the degassing portion 361 be present in the width direction of the fastening portion non-arranged portion 93 extending in the longitudinal direction. Further, from the viewpoint of gradually discharging the volatile component volatile gas, the length (H3) in the width direction of one degassing portion 361 is the length in the width direction of one fastening portion non-placement portion 93 (H3) More preferably it is smaller than H4).

The ratio (H3 / H4) of the length (H3) in the width direction of one degassing portion 361 in the sealing and fixing area 36 to the length (H4) in the width direction of one fixing portion non-arrangement portion 93 is From the viewpoint of enhancing the exhaustability of volatile gas, 1/10 or more is preferable, and 1/5 or more is more preferable. Further, the ratio (H3 / H4) is preferably 4/5 or less, more preferably 7/10 or less, from the viewpoint of suitably suppressing the outgas amount.

The length (H3) of the degassing portion 361 in the width direction is preferably 1.5 mm or more, and more preferably 3.0 mm or more, from the viewpoint of enhancing the exhaust of the volatile gas for avoiding the burst. Further, the length (H3) in the width direction of the degassing portion 361 is preferably 10 mm or less, more preferably 7.5 mm or less, from the viewpoint of gradually exhausting the gas so that the effect of the volatile component is maintained. .
The length (H4) in the width direction of the fastening portion non-arranged portion 93 is preferably 10 mm or more, and more preferably 15 mm or more, from the viewpoint of enhancing exhaust of volatile gas for avoiding breakage. Further, the length (H4) in the width direction of the fastening portion non-arranged portion 93 is the viewpoint of suppressing the rupture of the fusion seal area due to the increase of the movement amount of volatile gas. From the viewpoint of maintaining the fixability, 30 mm or less is preferable, and 25 mm or less is more preferable.

The width (W2) of the sealing fixing area 36 having the degassing part 361 in the longitudinal direction is preferably 0.5 mm or more from the viewpoint of gradually exhausting the gas so that the effect of the volatile component is maintained. .0 mm or more is more preferable. Further, the width (W2) of the sealing and fixing area 36 in the longitudinal direction is preferably 3.0 mm or less, more preferably 2.5 mm or less, from the viewpoint of enhancing the exhaust of the volatile gas for avoiding bursting.

In this structure (A2), the longitudinal outward discharge of the volatile component volatile gas can generate, for example, a pressing force on the individual package 30 as a driving force, as in the first embodiment.
For example, the volatile component volatile gas that collects on the surface 10B of the napkin 10 facing the garment when a force that squeezes inward from the outer surface 53 of the second folding end 33 is applied to the fastening portion non-arranged portion 93 Induced longitudinally along the The degassing portion 361 of the sealed and fixed area 36 is opened by the pressure of the volatilized gas to be induced, and the volatilized gas gradually escapes (arrow shown in FIG. 7C). In conjunction with this, the volatile gas on the outer surface 51 side of the folding central portion 31 gradually passes over the folding line L2 and can be exhausted from the degassing portion 361 of the sealing and fixing area 36 (arrow shown in FIG. 7 (B) ). Furthermore, the volatilized gas on the outer surface 52 side of the first folding end 32 may gradually be discharged from the degassing portion 361 of the sealing and fixing area 36, gradually crossing the folding lines L1 and L2. As a result, the volatilized gas of the volatile component is gradually accumulated in the individual package 30 without accumulating too much, and the burst of the individual package 30 is suppressed.

In the embodiment shown in FIG. 7C, the degassing portions 361 in the sealing and fixing area 36 are disposed on both sides of the opening tab tape 37. Thereby, the tab tape 37 for opening can suppress a burst of parts other than the gas release part 361, and is preferable. However, the degassing part 361 in the sealing and fixing area 36 is not limited to this aspect, and may take various forms that can communicate with the fastening part non-arranged part 93. In addition, the embodiment may not have the opening tab tape 37. It is preferable that the degassing portion 361 in the sealing and fixing area 36 be at least near the center in the width direction. For example, as shown in FIG. 8, a plurality of degassing portions 361 may be disposed along the sealing and fixing area 36 in addition to the vicinity of the center in the width direction as long as the sealing function is not inhibited.
Further, the fastening portion 8 may be divided into a plurality of stripes in the width direction so that the fastening portion non-arranged portions 93 in the longitudinal direction are arranged in a plurality of stripes in the width direction. In accordance with this, the degassing portion 361 in the sealing and fixing area 36 can be appropriately set in a range that does not impair the sealing function.

The arrangement of the opening tab tape 37 is preferably as follows. That is, when the volatile component is contained in the absorber 3 of the napkin 10, it is preferable that the fixed end 371 of the opening tab tape 37 be disposed at a position not overlapping the absorber 3 of the napkin 10. In this case, the absorbent body 3 is the absorbent body 3 at the second folding end 33 where the fixed end 371 of the opening tab tape 37 is directly disposed. Thereby, the fixing force of the opening tab tape 37 can be held without being affected by the action of the volatile gas of the volatile component in the absorber 3. In addition, it is preferable that the free end 372 of the opening tab tape 37 be disposed at a position overlapping the absorbent body 3 of the napkin 10. In this case, the absorbent body 3 is the absorbent body 3 at the first folded end 32 where the free end 372 of the opening tab tape 37 is directly disposed. Thereby, the free end 372 of the opening tab tape 37 is affected by the action of the volatile gas of the volatile component in the absorber 3, and the opening operability due to the decrease in the fixing force may be good.

Next, with reference to FIGS. 9A to 9C, the structure of the third embodiment for realizing the exhaust of the volatile gas will be described.

The third embodiment has the structure (A1) of the first embodiment and the structure (A2) of the second embodiment.
That is, on the surface 10B of the napkin 10 facing the garment, the fastening portions 8 extending in the width direction are arranged in a plurality of divisions and spaces in the width direction. A plurality of the arrays are arranged at regular intervals in the longitudinal direction. As a result, in the region 85 in which the plurality of fastening portions 8 are disposed, a fastening portion non-arranged portion 91 extending in the width direction and a fastening portion non-arranging portion 93 extending in the longitudinal direction are disposed. In addition, it has a non-arranged portion 92 having a predetermined width and extending in the longitudinal direction outward in the width direction of the region 85 where the anchoring portion 8 is disposed.

Thus, the structure (A1) communicating with the fastening part non-placement part 91 extending in the width direction and the gas vent part 341 in the fusion seal area 34, and the sealing fastening with the fastening part non-position part 93 extending in the longitudinal direction Both of the structure (A2) in communication with the degassing portion 361 in the region 36 are present in combination. Moreover, the structure (A1) and the structure (A2) cross each other and communicate with each other.
Therefore, in the third embodiment, the structure (A1) and the structure (A2) can be linked to each other to exhaust the volatile gas of the volatile component more efficiently. Thereby, rupture of the individual package 30 can be suppressed more suitably. Further, as described above, the fastening portion non-arranged portion 92 can disperse the volatile gas in the longitudinal direction while storing it once and exhaust the gas uniformly in the entire fusion seal area 34, which contributes to gradual exhaustion.

In the third embodiment, the number and arrangement of the fastening portion non-placement portion 91 and the fastening portion non-placement portion 93 are not limited to those shown in FIG. 9 and can be set variously.

The individual package 30 of the present embodiment gradually exhausts the volatile gas of the volatile component to prevent the packaging material from bursting even if any of the first to third embodiments described above is included. it can.
In addition, with the individual package 30 itself being less likely to expand, the loss of volatile components can be suppressed, and the sanitary condition of the packaging material can be maintained.

In the individual packaging body 30 of the present embodiment, the packaging material 20 is preferably one in which the surface of the fusion layer 24 is subjected to a peeling treatment (a material having a peeling treated layer). Thereby, the packaging material 20 causes the surface of the fusion layer 24 to directly contact the fastening portion 8 of the surface 10B of the napkin 10 facing the garment without interposing the release paper (the fastening portion 8 is It can be disposed opposite to the peeling treatment layer). Volatile components become volatile gas and volatilize toward the atmosphere from the inner side of the package where the gas concentration tends to be high, and the gas formed in the space formed between the napkin 10 of the individual package 30 and the packaging material 20 Is more likely to be stored. By bringing the packaging material 20 into direct contact with the fastening portion 8 of the napkin 10 without interposing the release paper, gas accumulation between the packaging material 20 and the release paper can be avoided. Thereby, the swelling of the individual package 30 due to the volatile gas can be further suppressed. Furthermore, the degassing part 361 of the sealing and fixing area 36, the fastening part

non-arranged parts

91, 92 and 93 formed between the napkin 10 and the packaging material 20, and the degassing part 341 of the fusion sealing area 34 Consecutive on the same plane is preferable because it leads to better communication. Moreover, in the degassing part 341 of the fusion | melting seal | sticker area | region 34, and the degassing part 361 of the sealing fixed area | region 36, since fusion | melting layer 24 comrades of the packaging material 20 comrades does not stick, smooth opening and closing may arise, and it is preferable.

In the individual package 30, the bulk softness of the packaging material 20 is preferably 13 cN or more. Thereby, the packaging material 20 is provided with the rigidity which suppresses the expansion by the pressure of volatile gas. In this respect, the bulk softness of the packaging material 20 is more preferably 20 cN or more, and still more preferably 40 cN or more. Moreover, from the viewpoint of the ease of taking out the napkin 10 from the individual package 30, the bulk softness of the packaging material 20 is preferably 75 cN or less, more preferably 65 cN or less, and still more preferably 60 cN or less. When the bulk softness differs between the machine flow direction (MD, Machine Direcion) and the cross direction (CD, Cross Direction) of the packaging material 20, the bulk softness in at least one of the directions should satisfy the above range preferable.

(Method of measuring bulk softness of packaging material 20)
The measurement method of bulk softness in the machine flow direction is as follows. The packaging material 20 is cut into a size of 30 mm along the machine flow direction and 150 mm along the width direction to obtain a rectangular test piece. From this test piece, a cylinder with a diameter of 45 mm is formed with the height in the direction of the short side (direction of 30 mm). The overlapping width of the cylinders in the circumferential direction is about 10 mm. The upper end and the lower end of the overlapped portion are the stapler HD-10D made of MAX, needle No. Fix with 10-1M. The maximum load when the cylindrical measurement sample obtained in this manner is compressed in the height direction of the cylinder is measured by a compression tester, and the value is taken as the value of bulk softness. As a compression tester, RTA-100 (trade name) manufactured by Orientec Co., Ltd. is used. The compression speed is 10 mm / min.
On the other hand, bulk softness in the width direction is obtained by cutting the packaging material 20 to a size of 30 mm along the width direction and 150 mm along the machine flow direction, collecting a rectangular test piece, and measuring it in the same manner as described above .

In the individual package 30, it is preferable that the application part of the volatile component mentioned above does not overlap with the fastening part 8 in the thickness direction of the napkin 10. When the application part of the volatile component does not overlap with the fastening part 8, the volatile gas of the volatile component is easily diffused from the back sheet 2 side to the fastening part non-arranged part 9 between the fastening parts 8. As a result, gradual exhaustion by the structures (A1) and (A2) described above is more likely to occur more effectively. Moreover, the diffusion of the volatile gas to the top sheet 1 side can be suppressed. Thereby, it is possible to suppress the decrease in the absorbability of the surface sheet 1 and the stimulation on the skin.
Furthermore, in the napkin 10 as a product, the liquid volatile component or volatile component-containing liquid may exude and spread even in the portion overlapping the fastening portion 8. In this case, the balance between the diffusion suppression of the volatile gas by the fastening portion 8 and the diffusion from the back sheet 2 side by the fastening portion non-arranged portion 9 may be controlled by the positional relationship between the fastening portion 8 and the application portion. it can. That is, the rupture of the individual package 30 can be suppressed while suitably retaining the effect of the volatile component.

In addition, it is preferable that the individual package 30 have the following structure from the viewpoint of more effectively avoiding breakage. The individual package 30 preferably has at least any one of the following, more preferably has two or more in combination, and still more preferably has all.

First, in each of the first and second

folding end portions

32 and 33, it is preferable that the napkin 10 has a shape in which the width narrows toward the front and rear end portions in the longitudinal direction (FIG. 10). Thereby, it is possible to widen the area 27 where the packaging materials 20 (the first fold packaging part 22 and the second fold packaging part 23) facing each other in which the napkin 10 is not disposed in the vicinity of the opening 35 are opposed. The area 27 where the packaging materials 20 face each other has low rigidity, and is an area where volatile gas can be temporarily stored. By this, even if the degassing rate may be lower than the volatilization rate, it is possible to suppress the burst of the individual package 30.

Second, at the second folding end 33 located on the upper side Z1 of the individual package 30, the distance between the longitudinal end edge of the napkin 10 and the opening end edge of the packaging material 20 corresponds to the longest position. It is preferable that the degassing part 361 does not exist in the portion 351 of the opening 35 (FIG. 10). The portion 351 of the opening 35 described above, in other words, the distance to the point at which the outer edge of the second folding end 33 of the napkin 10 intersects with the perpendicular when the perpendicular is extended from the opening end of the packaging material 20 Is the portion of the opening 35 corresponding to the longest position.
In this portion, the opening port 35 is preferably sealed to be a bag-like portion capable of temporarily storing volatile gas. As a result, the accumulated gas is prevented from escaping from the inside of the individual package 30 into the atmosphere, and the volatile gas can be accumulated to a predetermined concentration in the low rigidity area 27 where the napkin 10 is not disposed. Is maintained at a predetermined concentration and is in an equilibrium state in the region 27, the volatilization of the volatile component can be suppressed.

Third, in the overlapping portion between the first folding end 32 and the second folding end 33, a region where the napkin 10 does not exist inside the imaginary lines K1 and K2 drawn along the side edges of the napkin 10 It is preferred to have 27 (Figure 10). As described above, the area 27 has a low rigidity and can temporarily store volatile gas, so that expansion and rupture of the individual package 30 can be suppressed.

Fourth, in each of the first folding end 32 and the second folding end 33, the fastening portion 8 is preferably not disposed at the longitudinal end of the napkin 10 (FIG. 10). The term "longitudinal end of the napkin 10" as used herein refers to the longitudinal front and rear end regions of the front portion F and the rear portion R of the napkin 10. Since there is no fastening portion in this portion, a space is formed between the packaging material 20 (the second fold packaging portion 23) and the napkin 10, the volatile gas is stored to a predetermined concentration, and the equilibrium state is established. Can be suppressed. Not only that, in the vicinity of the space in the longitudinal direction end region of the napkin 10, since the napkin 10 and the packaging material 20 are in close contact with the fastening portion 8, the space is very small and the expansion is suppressed. Therefore, while the gas concentration in the space of the longitudinal end area of the napkin 10 tends to be denser, adjacent space areas (for example, the area 27 in FIG. 10) in which the packaging materials 20 overlap with each other without intervening napkins. On the other hand, a large space is formed, the gas concentration is diluted, and the gas concentration difference is generated. Thereby, it becomes easy to exhaust air from the

degassing part

341 and 361 from the longitudinal direction end part area | region of the napkin 10 through the space area | region where the surrounding packaging material 20 comrades overlap.

In relation to the above, the fastening portion 8 is preferably in a region corresponding to the arrangement of the absorber 3 in the surface 10B facing the garment. Thereby, at the time of use of the napkin 10, the fixation property to clothing can be improved in the part by which the rigidity of the napkin 10 was raised by the thickness of the absorber 3. FIG. Further, in the individual wrapping body 30, a relatively soft portion other than the portion where the rigidity of the napkin 10 is enhanced becomes the fastening portion non-arranged portion 94 (FIG. 10). Thereby, when the volatile component volatile gas is temporarily stored in the space with the packaging material 20, the fastening portion non-placement portion 94 enables appropriate swelling with the influence of the rigidity of the absorber 3 suppressed. , Bursting is more likely to be avoided.

Fifth, in the napkin 10, in the structure of the top sheet 1, the back sheet 2 and the absorber 3 described above, it is preferable that a volatile component is disposed in the absorber 3. Thereby, in the folded individual package 30, excessive diffusion of volatile gas can be suppressed. In addition, the volatility of volatile components can be suppressed. In addition, since the volatile component is at the middle position of the thickness of the napkin 10, movement of the volatile gas to the back sheet 2 side is likely to occur.

From the viewpoint of further enhancing the above-mentioned effects, as shown in FIG. 11, it is preferable that the absorbent 3 containing a volatile component is composed of a central absorbent sheet 3A and a main absorbent sheet 3B which wraps the central absorbent sheet 3A. The central absorbent sheet 3A is folded in three at both ends in the width direction, and the main absorbent sheet 3B is folded in three at both ends in the width direction so as to be further wrapped around it. Thus, in the folded structure of the individual package 30, the volatility of the volatile component is more effectively suppressed in the structure in which the absorbers 3 are stacked in layers. In particular, in such a laminated structure of the absorbent body 3, it is preferable that the central absorbent sheet 3A has a volatile component. It is preferable that at least the application part of the volatile component described above be in the central absorbent sheet 3A.

Sixth, in each of the first and second

folding end portions

32 and 33, it is preferable that the absorbent body 3 has a shape in which the width is narrowed toward the distal end portion in the longitudinal direction of the napkin (FIG. 10). By this, it is possible to widen the region 28 where the absorber 3 is not disposed near the opening 35, and it is possible to temporarily store the volatile gas and to suppress expansion and rupture of the individual package 30.

Seventh, in each of the first and second

folding end portions

32 and 33, preferably, the fastening portion 8 is not disposed in the region 28 where the above-described absorber 3 is not disposed (FIG. 10). Thereby, the volatile gas mentioned above can be stored temporarily, and the effect which suppresses expansion and rupture of the individual packaging body 30 can be heightened further.

In the absorbent article (napkin 10), when the volatile component is disposed in the central region in the width direction X, the volatile component should be set so as to relieve the stimulation of sensitive parts such as the buttocks. Becomes easy. Moreover, arrangement | positioning of the said volatile component is preferable from a viewpoint of suppressing the excessive transpiration | evaporation of a volatile component, when an individual package has a structure (A1), and when having a structure (A2), a degassing part It is preferable from the point of view of the communication. In particular, when the volatile component is a cooling agent, it is preferable because it is possible to selectively exert a cooling sensation effect by avoiding a part sensitive to irritation such as a buttock in the absorbent article. In the individual package, the volatile component is disposed so as to overlap the fastening portion non-arranged portion 9 in plan view in the central region in the width direction of the absorbent article (napkin 10). Is preferable because it is easy to move to the degassing part. In addition, the center area | region of the width direction is an area | region located in the center at the time of dividing the absorber of an absorbent article into three equally in the width direction.

On the other hand, the volatile component may be disposed along the longitudinal direction Y in order to exert the effect of the volatile component in a wide range in the absorbent article, but excessive transpiration of the volatile component is suppressed. From the viewpoint, it is preferable to dispose at least in the middle.
