Description

Individual packaging of absorbent articles

The present invention relates to an individual package of an absorbent article having a structure in which an absorbent article and a packaging material for packaging the same are integrally folded.

In the past, absorbent articles such as menstrual napkins have been folded into individual packages together with packaging materials, and are commercially available. A typical form of the individual package of the absorbent article includes an absorbent article having a shape that is long in the upward direction and a rectangular shape packaging material that is individually packaged, and the packaging material and the absorbent article. The configuration is also performed by folding three times in the longitudinal direction thereof (see Patent Documents 1 to 3). Moreover, in the individual package body of this structure, as a fixing method for sealing individual packages, it is known that the one end portion of the package material forming the upper surface of the individual package body is also referred to as a joint tape (tab). A method of fixing a tape for individual package sealing such as tape, or a method of arranging an adhesive for sealing individual packages between packaging materials (see Patent Documents 1 and 2).

In the fixing method for sealing individual packages, the method of using the fixing tape is to fix the absorbent article three times in the longitudinal direction to form an individual package, and then fix it to the packaging material. Further, in the above method of using the adhesive for sealing individual packages, when the absorbent article is folded three times in the longitudinal direction to form an individual package, the adhesive portion is formed, and the adhesive portion is placed in the layer which is folded in the first time. Between the upper surface of the packaging material and the lower surface of the packaging material in the second and finally folded layer, the two sides of the packaging material are peeled off from each other. In the form of the end portion formed by the adhesive for sealing the individual package body, the last package is formed. The end portion of the folded packaging material itself becomes the sealing portion of the individual package. According to the individual package sealing method, the opening of the individual package is in a capped state, and it is easy to maintain the sanitary state of the inner absorbent article.

Further, in the absorbent article such as menstrual napkins, the absorbent body in the absorbent article is disposed opposite to the excretory portion such as the vaginal opening of the wearer in terms of ensuring the absorption capacity and improving the conformability. The portion having a larger thickness than the peripheral portion is referred to (see Patent Document 4).

As shown in FIGS. 4 and 5, the absorbent core 4 has a standard absorbent portion 40 and a protruding portion 41 having a larger thickness than the standard absorbent portion 40. In the first embodiment, the standard absorbing portion 40 is in a region where the thickness and the basis weight of the absorbent core 4 are relatively small, and the protruding portion 41 is tied to the thickness and the basis weight of the absorbent core 4. In the relatively large area, the front side and the rear side of the longitudinal direction X of the absorbent core 4 are respectively the standard absorbing portions 40, and the central portion of the longitudinal direction X sandwiched by the pair of front and rear standard absorbing portions 40, 40 is the protruding portion 41. . As shown in Fig. 4, the protruding portion 41 in the first embodiment extends from the front side A of the tampon 1 to the rear portion C via the crotch portion B, and has a hexagonal shape in plan view.

In the first embodiment, as shown in FIGS. 4 and 5, the protruding portion 41 has a maximum width portion 42 extending over the entire length of the lateral direction Y of the absorbent core 4, that is, the full width; the front side convex portion 43, The maximum width portion 42 is formed in front of the longitudinal direction X; and the rear side convex portion 44 is formed from the maximum width portion 42 in the longitudinal direction X. The portions marked with oblique lines in the figure are the two convex portions 43, 44. The absorbent core 4 is formed symmetrically with respect to the imaginary longitudinal center line CLx which bisects the absorbent core 4 in the longitudinal direction X and extends in the lateral direction Y.

As shown in FIG. 4, the maximum width portion 42 is disposed on the entire lower portion B and has a quadrangular shape (rectangular shape) in plan view. One of the pair of side edges 420, 420 of the maximum width portion 42 extending in the longitudinal direction X forms a portion (the lower portion B) where the largest width portion 42 of the absorbent core 4 exists. Both sides. In this way, the protruding portion 41 (the maximum width portion 42) that plays an important role in the performance of the characteristics such as the conformability and the leakproof property exists over the entire width of the absorbent core 4 in the crotch portion B, thereby, for example, When the wearing position of the sanitary napkin 1 is slightly shifted from the proper position in the lateral direction Y due to the activity of the wearer, the protruding portion 41 (the maximum width portion 42) can still abut against the intercondylar portion of the wearer. Therefore, the sanitary napkin 1 is excellent in the followability, the conformability, and the leakproofness of the wearer's activities.

On the other hand, as shown in FIG. 4, the front side convex portion 43 is disposed so that the longitudinal direction X crosses the second bending line 22 which constitutes the boundary between the front portion A and the lower portion B, and the rear side convex portion 44 is The longitudinal direction X is disposed so as to straddle the first bending line 21 that forms the boundary between the rear portion C and the lower portion B. As shown in FIG. 4, the front side convex portion 43 has an isosceles triangular shape in plan view, is connected to both side edges 420 and 420 of the maximum width portion 42, and has a plan view V constituting both sides of the equal waist triangle. The longitudinal end 430 of the font. Similarly, the rear side convex portion 44 is also in the shape of an isosceles triangle, is connected to the both side edges 420 and 420 of the maximum width portion 42, and has a longitudinal V-shaped longitudinal end constituting both sides of the equal waist triangle having the same length. 440. The longitudinal end 430 of the front side convex portion 43 and the longitudinal end 440 of the rear side convex portion 44 are respectively disposed such that the V-shaped top portions 431 and 441 protrude toward the outer side of the longitudinal direction X.

The maximum width portion 42 is integrally formed with the two convex portions 43, 44. In the present specification, the term “integral molding” means that a plurality of portions, for example, the front side convex portion 43 and the maximum width portion 42 are integrated without being bonded by a bonding method such as an adhesive or hot melt, and are integrally formed of the same material. When a plurality of parts of the absorbent core 4 are integrally molded, the continuity of the excretion liquid such as menstrual blood can be smoothly moved.

In the first embodiment, as shown in FIG. 5, the protruding portion 41 of the absorbent core 4 protrudes from the non-skin opposing surface 40b of the standard absorbent portion 40 toward the non-skin side sheet 3. So, as an absorbent core The protruding portion 41 of one of the bodies 4 protrudes further toward the non-skin side sheet 3 than the standard absorbent portion 40 as the peripheral portion thereof, whereby the standard absorption of the absorbent core 4 is as shown in FIGS. 2 and 5. A space portion 47 is formed between the non-skin opposing surface 40b of the portion 40 and the non-skin side sheet 3.

In the first embodiment, as shown in FIG. 4, a groove 45 is formed in the standard absorption portion 40 along the longitudinal end 430 of the front side convex portion 43 and the longitudinal end 440 of the rear side convex portion 44. Further, on the outer side of the longitudinal direction X of the groove 45, a plurality of linear grooves 46 extend in the longitudinal direction X, and a plurality of linear grooves 46 are also extended in the lateral direction Y, and may be arranged in a lattice by orthogonal to each other. A plurality of linear grooves 46 divide the standard absorbing portion 40 into a plurality of small regions, and in the first embodiment, grooves 46 are formed. The groove 45 is connected to the groove 46. In the standard absorption portion 40, the small region is a relatively high basis weight with a relatively large basis weight, and the formation portions of the grooves 45, 46 are low basis weight portions having a relatively small basis weight. Further, in the first embodiment, as shown in FIG. 5, the groove 45 has an opening on the non-skin opposing surface 40b of the standard absorbent portion 40, and the bottom of the groove 45 is formed on the skin facing surface 40a side of the standard absorbent portion 40. Although not shown, the groove 46 also has an opening in the non-skin opposing surface 40b of the standard absorbent portion 40. Furthermore, the grooves 45, 46 may have openings opposite to the skin facing surface 40a of the standard absorbent portion 40.

The grooves 45 and 46 of the standard absorbing portion 40 are intentionally made by the fiber forming amount of the core forming material containing the absorbent material in a manufacturing method of a known absorbent core using a fiber stacking device. The concave portion formed by the reduction is not a so-called embossed groove, that is, a concave portion formed by embossing (pressing treatment) of a flat plate-shaped absorbent core having a uniform basis weight and no unevenness on the surface. Therefore, in general, the embossing groove is formed by embossing the core forming material, so that it is denser than the peripheral portion, but the grooves 45 and 46 are not densified during the formation thereof, so There is no substantial difference in density between the peripheral portions (non-groove forming portions). Further, in general, the embossed groove has no substantial difference in basis weight as compared with the peripheral portion thereof, but the grooves 45 and 46 have a lower basis weight than the peripheral portion thereof.

A known method for producing an absorbent core which can be used for the formation of the grooves 45, 46 has a step of suction-stacking the core forming material supplied, for example, by the air flow, to be formed outside the fiber stacking device (drum, etc.) The bottom of the concave portion for accumulating the surface, in this step, by using the concave portion for the accumulation which is partially different in the opening ratio of the bottom portion, specifically, the opening ratio corresponding to the bottom portion of the predetermined portion of the grooves 45, 46 is used. By adjusting to a relatively low accumulation recess, it is possible to form the absorbent core 4 having a portion in which the thin walls of the grooves 45 and 46 are formed and a low basis weight and a portion having a thick wall and a high basis weight in which no grooves (recesses) are formed. .

The absorptive core 4 in the first embodiment is formed by partially varying the amount of fibers deposited in the core forming material, and the portion in which the amount of fibers deposited in the core forming material is relatively small is the standard absorbent portion 40, and the core The portion where the fiber accumulation amount of the bulk forming material is relatively large includes the maximum width portion 42, the front side convex portion 43, and the protruding portion 41 of the rear side convex portion 44. Therefore, the protruding portion 41 is formed not only in thickness but also in basis weight, and the basis weight is formed larger than the standard absorbing portion 40.

The standard absorbent portion 40 of the menstrual sanitary napkin 1 can also be configured as a block structure having a plurality of relatively small basis weights, i.e., the small regions surrounded by the grooves 45, 46 and a relatively low line surrounding the small regions. In the first embodiment, as shown in Fig. 4, the base portion of each of the base portions 45 and 46 is formed as the above-described structure. Since the standard absorbent portion 40 has a block structure, the absorbent core 4 is soft in both the longitudinal direction X and the lateral direction Y. Therefore, the absorbent core 4 is easily conformed to the shape of the wearer's body. Further, since the excrement such as menstrual blood can be guided to the portion where the grooves 45 and 46 having a relatively small thickness are formed and flow therethrough, the liquid diffusion property of the longitudinal direction X and the lateral direction Y of the absorbent core 4 is excellent.

The individual package 20 of the first embodiment is manufactured by laminating the first folded region 12 to the central region by the first bending line 21 in the laminated body 10 in the unfolded state as shown in FIG. 11 , and then, the second folding region 13 is superposed on the first bending line 22 to the first On the folded region 12, the extension portion of the packaging material 9 from the side edges along the longitudinal direction X of the sanitary napkin 1 is joined to each other by a known joining method such as an adhesive or a heat seal to form a sealing portion 23 ( Referring to Fig. 1(a)), the fixing tape 30 is placed at the above specific position.

Here, when the configuration in which the main features of the individual packages 20 of the first embodiment are particularly closely related, the protruding portion 41 of the absorbent core 4 is extended from the central region 11 across one bending line 21. The first folded region exposed portion 122 (see FIGS. 2 to 4) is formed as an isosceles triangle shape in plan view as shown in FIG. 4 as the extended portion, and is away from the central region 11 as shown in FIG. The length of the lateral direction Y, that is, the width, gradually decreases as it goes toward the outer side of the longitudinal direction X. Further, as shown in FIG. 1, the rear side convex portion 44 does not reach the boundary 91 between the first folded region exposed portion 122 and the second folded region 13, and there is a standard absorption between the rear side convex portion 44 and the boundary 91. Department 40.

Further, as one of the main features of the individual package 20 of the first embodiment, as shown in FIG. 1, the orientation of the fixing tape 30 and the protruding portion 41 in the plan view of the first folding region exposed portion 122 is as follows. The rear side convex portion 44, which is an extension of the first folded region exposed portion 122, overlaps. In other words, the fixing tape 30 overlaps the longitudinal end 440 of the rear side convex portion 44 at the boundary between the rear side convex portion 44 and the standard absorbing portion 40 in the first folded region exposed portion 122.

When the unopened individual package 20 shown in Figs. 1(a) and 2 is unsealed, the following operation is generally performed: the free end portion 32 of the fixing tape 30 is pinched by fingers, and exposed from the first folded region. The upper surface of the portion 122 is peeled off, and the fixing tape 30 is directly pulled, and the packaging materials 9 joined by the sealing portion 23 are peeled off from each other.

However, in the individual package 20 of the first embodiment, the position at which the longitudinal end 440 of the side convex portion 44 is formed after the boundary between the rear side convex portion 44 and the standard absorption portion 40 is formed is caused by the difference in thickness between the two. The resulting difference (see Figures 2 and 5). Further, in the individual package 20 of the first embodiment, as described above, the fixing tape 30 overlaps with the longitudinal end 440 of the rear side convex portion 44, That is, when the step is overlapped with the above-described step, when the free end portion 32 of the fixing tape 30 in the unpackaged individual package 20 is to be pinched by a finger, the fingertip of the finger (for example, the index finger) is used from above. When the pressure of the fixing tape 30 is pressed, the individual packages 20 are compressed in the thickness direction around the lower portion of the fixing tape 30. At this time, the members facing each other, for example, the non-skin side sheets 3, are interposed by the above-described step. The standard absorbing portion 40 is in close contact. As a result, in the individual package 20, as shown in Fig. 6, the thickness of the fixed end portion 31 of the fixing tape 30 and the lower portion thereof is smaller than the thickness of the lower end portion of the free end portion 32 and its vicinity, and the free end Since the portion 32 is easily lifted from the upper surface of the first folding region exposed portion 122, the free end portion 32 can be easily pinched by the fingers, even if the overlapping portion of the thick-walled protruding portion 41 is bulged. In the case of fluffy, the subsequent unsealing operation can be carried out smoothly and quickly. Moreover, this operation can be easily performed without being greatly affected by the ease of pinching of the free end portion 32 of the fixing tape 30.

Further, in the first embodiment, the protruding portion 41 of the absorbent core 4 is extended from the central region 11 by one bending line 22 to the second folding region 13 (see Figs. 2 to 4), as shown in Fig. 1. It is to be noted that the front side convex portion 43 as the extension portion does not reach the front side longitudinal end 40E of the standard absorption portion 40, and there is a cause between the front side convex portion 43 and the fixing tape 30 (fixed end portion 31). The difference in thickness between the front side convex portion 43 and the standard absorption portion 40 is a step difference. Therefore, in the first embodiment, the individual package 20 when the fixing tape 30 is pressed from above due to the presence of the step on the side of the rear side convex portion 44 and the step on the side of the front side convex portion 43 The degree of compression becomes relatively large, and therefore, the free end portion 32 of the fixing tape 30 is more easily lifted from the upper surface of the first folded region exposed portion 122.

Further, in the first embodiment, as shown in FIGS. 2 and 5, the protruding portion 41 including the maximum width portion 42, the front side convex portion 43, and the rear side convex portion 44 is not the skin of the standard absorbent portion 40 of the peripheral portion. The position of the facing surface 40b protrudes toward the non-skin side sheet 3 side, whereby the standard absorbing portion 40 and the non- Since the space portion 47 is formed between the skin side sheets 3, the degree of compression of the individual packages 20 when the fixing tape 30 is pressed from above is further increased, and the ease of pinching of the free end portions 32 is further improved. Further, the viewpoint of the effect of the formation of the space portion 47 is further exerted, and the height of the space portion 47, that is, the protruding height of the protruding portion 41P, from the viewpoints of the conformability and the leakproofness of the sanitary napkin 1 and the like. H (see Fig. 5) is preferably 0.5 mm or more, more preferably 1.0 mm or more, further preferably 15 mm or less, and further preferably 10 mm or less.

Further, in the first embodiment, as shown in Fig. 1(b), in the opposing surface of the fixing tape 30 opposed to the first folded region exposed portion 122, the free end portion 32 side is opposite to the first folding. The region exposed portion 122 does not have the adhesive non-adjacent portion 33, and when the remaining portion is the rear portion 34, the fixing tape 30 is next in a plan view of the first folded region exposed portion 122 as shown in FIG. 1(b). The portion 34 of the protruding portion 41 that faces the extending portion of the first folded region exposed portion 122, that is, the length of the lateral direction Y in the rear side convex portion 44, that is, the portion (the minimum width portion) having the shortest width overlaps. In the embodiment shown in Fig. 1(b), the minimum width portion is the front end portion 441 and the vicinity of the front end portion of the longitudinal end 440 of the rear side convex portion 44. In general, the portion where the adhesive portion 34 is present is a portion that is easily pressed by a finger such as the index finger when the free end portion 32 of the fixing tape 30 is to be pinched by a finger, and the portion which is easily compressed in the thickness direction is the end portion. 34. The minimum width portion of the rear side convex portion 44 is overlapped with a portion due to the difference in thickness between the rear side convex portion 44 and the standard absorption portion 40, whereby the free end of the fixing tape 30 can be further improved. The pinching of the part 32 is easy.

Further, in the first embodiment, as shown in Fig. 1(a), the fixing tape 30 is disposed at the center of the lateral direction Y of the individual package 20, whereby the free end portion of the fixing tape 30 is pinched and pulled by fingers. At 32 o'clock, the degree of freedom in the stretching direction is high, and not only the longitudinal direction X can be pulled in parallel, but also the direction in which the longitudinal direction X intersects can be pulled, so that the opening workability of the individual packages 20 is improved.

Further, in the first embodiment, as shown in Fig. 1, the rear side convex portion 44 and the standard suction The intersection of the receiving portion 40, that is, the portion of the longitudinal end 440 of the rear side convex portion 44 that overlaps with the fixing tape 30 in plan view has a V-shape having a top portion 441 that protrudes toward the fixed end portion 31 side of the fixing tape 30, and thus The direction of stretching when the finger is gripped and pulled by the free end portion 32 of the fixing tape 30 can be selected to be present in the left and right longitudinal ends 440, 440 with respect to the left and right sides 441 in addition to the longitudinal direction X. The direction of the orthogonality. On the other hand, for example, in the individual package of the prior absorbent article having the high portion (projecting portion) of the typical quadrangular shape, the longitudinal end of the middle and high portions overlapping the fixing tape is a linear line extending in the lateral direction. Therefore, as the stretching direction when the finger is used to pinch and pull the free end of the fixing tape, there is only one choice in the longitudinal direction. As described above, the individual package 20 of the first embodiment, in addition to the fixing tape 30, is disposed at the center of the lateral direction Y of the individual package 20, and can cope with various opening methods.

From the viewpoint of more effectively exhibiting the above-described effects, it is preferable that the first folding region exposed portion 122 and the central portion of the lateral direction Y on the side of the first bending line 21 (more specifically, the rear convex portion 44) The rigidity of the arrangement portion is the highest, and the rigidity of the both ends of the lateral direction Y on the side of the first bending line 21 (more specifically, the non-arrangement portion of the side convex portion 44 on the side of the first bending line 21) is the lowest. The other parts have rigidity in the middle of the two parts. Here, the "part of the first folding region exposed portion 122 on the first bending line 21 side" means the first folding line 21 from the first bending line 21 to the first folding region exposed portion 122 in the unopened state. The side of the boundary 91 with the second folded region is an area within 5 mm. By the rigidity of each portion of the first folded region exposed portion 122, such a large-scale relationship is established, and the individual packages 20 as a whole are easily bent at the boundary between the portions where the rigidity is different, for example, in the individual package 20 When the free end portion 32 of the fixing tape 30 is to be pinched by a finger at the time of opening, the ease of pinching the free end portion 32 can be further improved by performing the opening operation of the entire package body 20 as a whole. In general, the rigidity of each portion of the individual package 20 is proportional to the basis weight, so that the first folded region exposed portion 122 is provided as described above. The rigidity is poor, as long as the portion having a relatively high rigidity is a high basis weight, the portion having a relatively low rigidity is a low basis weight, and the portion having a rigidity in the middle thereof is a basis weight in the middle thereof. can. In the first embodiment, the protruding portion 41 has the maximum width portion 42 extending over the entire length of the lateral direction Y of the absorbent core 4, and the rear protruding portion 44 is bent by the first bending line 21, so that the first portion In the vicinity of the center portion of the lateral direction Y on the side of the bending line 21, the protruding portions 41 are arranged to overlap each other, and the standard absorption portion 40 is overlapped at both end portions of the lateral direction Y on the side of the first bending line 21, so that the first folded region exposed portion 122 is given The rigidity as described above is poor.

From the viewpoint of further exerting the above-described effects, the size and the like of each of the protruding portions 41 including the maximum width portion 42, the front side convex portion 43, and the rear side convex portion 44 are preferably set as follows.

The basis weight of the protruding portion 41 is preferably 100 g/m ² or more, more preferably 200 g/m ² or more, further preferably 1,500 g/m ² or less, and further preferably 1200 g/m ² or less.

The length of the longitudinal direction X of the maximum width portion 42 (the length of the side edge 420) is preferably 20% or more, more preferably 25% or more, and more preferably 90% of the total length of the longitudinal direction X of the absorbent core 4. % or less, further preferably 75% or less.

The length of the longitudinal direction X of the maximum width portion 42 (the length of the side edge 420) is preferably 20 mm or more, more preferably 25 mm or more, and is preferably 360 mm or less, and more preferably 300 mm or less.

The length L1 (see FIG. 4) of the longitudinal direction X of the front side convex portion 43 and the rear side convex portion 44 is preferably 5% or more, and more preferably 10% or more with respect to the entire length of the longitudinal direction X of the absorbent core 4, respectively. Further, it is preferably 50% or less, and more preferably 30% or less.

The length L1 is preferably 5 mm or more, more preferably 10 mm or more, and is preferably 200 mm or less, and more preferably 120 mm or less.

Another embodiment of the individual package of the absorbent article of the present invention is shown in Figs. 7 to 9 . In the other embodiment, the components that are different from the individual packages 20 of the first embodiment will be mainly described, and the same components will be denoted by the same reference numerals and will not be described. The individual package 20 of the first embodiment will be appropriately applied to the components that are not particularly described.

In the individual package 20, the protruding portion 41 protrudes from the surface position (non-skin opposing surface 40b) of the standard absorbing portion 40 toward the non-skin side sheet 3 (refer to FIG. 5), but the individual packaging shown in FIG. In the body 20A, the protruding portion 41 is opposite to the surface position (the skin facing surface 40a) of the standard absorbent portion 40 and protrudes toward the skin-side sheet 2 side. In other words, in the individual package 20A, the protruding portion 41 has a protruding portion 41P that protrudes from the skin facing surface 40a of the standard absorbent portion 40 toward the skin-side sheet 2 side. Therefore, in the individual package 20A, between the skin facing surface 40a of the standard absorbent portion 40 of the absorbent core 4 and the skin side sheet 2, the non-skin opposing surface 40b of the standard absorbent portion 40 is formed. The space portion of the space portion 47 (see FIG. 5) between the skin side sheets 3 is the same as the space portion. Therefore, the free end portion 32 of the individual package body 20A is excellent in pinching ease.

In the individual packages 20 and 20A according to the first embodiment of the present invention, the fixing tape 30 separated from the individual packages 20 and 20A is provided as a sealing portion and a sealing portion for opening the individual packages in an unused state. The individual package 20B which is the second embodiment of the present invention is not provided with such a fixing tape, and the packaging material 9 which is a constituent member of the individual package 20B (which is folded together with the menstrual napkin 1) is replaced by The one end portion of the packaging material 9 in the longitudinal direction functions as a sealing portion of the individual package in an unused state and a sealing portion for opening the package.

In the individual package 20B of the second embodiment, as shown in FIG. 8, the first folded region covering portion 121 is covered on the upper surface of the first folded region covering portion 121 or in the unused state of the individual package 20B. The fixing adhesive 35 is disposed on the lower surface of the second folding region 13 on the upper surface, and the second folding region 13 is covered with the first folding region coating portion 121 via the fixing adhesive 35. It is freely peeled off. The fixing adhesive 35 in the second embodiment has a continuous linear shape in plan view, and the second folding region 13 of the packaging material 9 among the overlapping portions of the first folding region covering portion 121 and the second folding region 13 The longitudinal X-ends 91 of the sides extend at a predetermined distance in the longitudinal direction X and extend over substantially the entire length of the lateral direction Y of the overlapping portions. The width of the fixing adhesive 35 (the length of the longitudinal direction X) is preferably 0.5 to 5 mm. In the packaging material 9, the longitudinal end portion 92 sandwiched by the longitudinal X-end 91 of the packaging material 9 and the fixing adhesive 35 is not adjacent to the first folding region covering portion 121 located directly below the packaging member 9, and When the individual package 20B is opened, the pinch-out portion for pinching is pinched by a finger to function.

Further, in the individual package 20B of the second embodiment, as shown in FIG. 8, the rear side convex portion 44 which is the extended portion of the protruding portion 41 facing the first folded region exposed portion 122 is away from the first bending line. 21, the width gradually decreases, and reaches the boundary between the first folded region exposed portion 122 and the second folded region 13, that is, the longitudinal X end 91 of the packaging material 9. More specifically, the rear side projection 44 spans the longitudinal X-end 91 of the packaging material 9 in the longitudinal direction X, with its top 441 overlapping the longitudinal end region 92 of the packaging material 9. Further, in the individual package 20B of the second embodiment, as shown in FIG. 8, the fixing adhesive 35 does not extend toward the extending portion of the protruding portion 41 toward the first folded region exposed portion 122. The side convex portions 44 are overlapped, and a standard absorption portion 40 is present between the rear side convex portion 44 and the fixing adhesive 35.

In the individual package 20B of the second embodiment, which is configured as described above, similarly to the individual packages 20 and 20A of the first embodiment, the side convex portion after the boundary between the rear side convex portion 44 and the standard absorption portion 40 is formed. The formation position of the longitudinal end 440 of 44 produces a step difference due to the difference in thickness between the two. Further, in the individual package 20B, as described above, the longitudinal end portion 92 of the packaging member 9 overlaps with the longitudinal end 440 of the rear side convex portion 44, that is, overlaps with the above-described step difference, so that it is intended to be pinched by fingers as usual. The longitudinal end region 92 in the individual package 20B in an unopened state At the time of pressing the longitudinal end portion 92 from above by the fingertip of the finger (for example, the index finger), the individual package 20B is compressed in the thickness direction around the lower portion of the longitudinal end portion 92. At this time, the opposing members, for example, the non-skin side sheet 3 and the standard absorbing portion 40 are in close contact with each other via the above-described step. As a result, in the individual package 20B, as shown in FIG. 9, the thickness of the fixing adhesive 35 and the lower portion in the vicinity thereof is smaller than the thickness of the longitudinal end portion 92 of the packaging material 9 and the lower portion thereof. The longitudinal end portion 92 is easily lifted from the upper surface of the first folded region exposed portion 122, so that the longitudinal end portion 92 can be easily pinched by fingers, so that the subsequent opening can be smoothly and quickly performed. operating.

The planar shape of the fixing adhesive 35 is not limited to a continuous linear shape parallel to the lateral direction Y as shown in FIG. 8, and may be a shape extending in the lateral direction Y, and may be, for example, a curved line, a wavy line, a zigzag line, or the like. Further, it may be a discontinuous line in which the adhesive attaching portion and the adhesive non-adhering portion are alternately arranged in the lateral direction Y and integrally extend in the lateral direction Y. When the fixing adhesive 35 is not continuously attached, the imaginary line connecting the plurality of adhesive adhering portions is satisfied with the extending portion of the protruding portion 41 facing the first folded region exposed portion 122 (rear The positional relationship of the side convex portions 44) and the like may be sufficient. Further, a plurality of fixing adhesives 35 extending in the lateral direction Y may be present. In this case, the boundary between the exposed portion 122 and the second folded region 13 closest to the first folding region (the longitudinal X end of the packaging material 9) may be used. The fixing adhesive 35 of 91) may satisfy the positional relationship with the extending portion (the rear side convex portion 44) of the protruding portion 41 facing the first folding region exposed portion 122. As the fixing adhesive 35, the same material (adhesive) as the above-mentioned forming portion of the fixing tape 30 of the individual package 20 described above can be used.

The present invention has been described above based on the embodiments thereof, but the present invention is not limited to the above embodiments, and can be appropriately modified.

For example, it may be bent in the protruding portion 41 (the front side convex portion 43 and the rear side convex portion 44) A groove (not shown) is formed in a portion where the wires 21 and 22 overlap, and the groove of the protruding portion 41 can have an opening on the skin facing surface of the protruding portion 41 (opposite to the skin side sheet 2), and can also protrude The non-skin opposing surface of the portion 41 (opposite the non-skin side sheet 3) has an opening. As described above, if the projections 41 are formed with the grooves along the bending lines 21 and 22, the projections 41 are easily bent along the grooves, so that when the individual packages 20 are unsealed, the individual packages 20 are moved along The opening operation of the groove is curved, and the ease of pinching of the free end portion 32 can be further improved. Moreover, from the viewpoint of improving absorption or leakproofness, the skin side sheet 2 and the absorbent core 4 (the above-mentioned coated core material covering the skin facing surface of the absorbent core 4) may be used. The intervening arrangement comprises a variety of non-woven liquid permeable sheets.

Only parts of the above-described one embodiment may be used as appropriate. For example, in an individual package of an absorbent article in which a part of the packaging material which is folded together with the absorbent article as in the case of the individual package 20B is used as a sealing portion of the individual package and a sealing portion for opening the sealing member, A fixing tape may be disposed on the upper surface of the individual package in the same manner as the fixing tape 30 in the individual package 20.
