Description

201023839 VI. Description of the Invention: [Technical Field] The present invention relates to a single package of an absorbent article in which an absorbent article such as menstrual napkin is individually packaged. [Prior Art] Absorbent articles such as menstrual sanitary napkins or incontinence guards, as a general constitution thereof, have a structure in which an absorbent body is provided between the front sheet and the back sheet. In recent years, I have improved the adhesion of the absorbent articles to the body or the leakage prevention, etc., and the development of a volume in the central portion in the width direction of the article from the lower abdomen side to the buttocks increases the volume of the absorbent body, and makes the portion facing Absorbent articles that are raised from the side of the user's skin. For example, Japanese Laid-Open Patent Publication No. 2000-189456 discloses that the middle-high ridge portion is formed in two places corresponding to the user's excretory portion and the user's buttocks, and the ridge portion is formed. The part is used as a menstrual sanitary napkin that bends the flexible region with lower rigidity. Further, Japanese Laid-Open Patent Publication No. 2006-239162 discloses an absorbent article having a middle portion of an absorbent body which is divided into two portions of a front ventral side and a rear dorso side. The absorbent article can be protruded toward the skin by the absorbent body to improve the conformability, suppress the leakage of the discharged liquid, and the like, and the middle and high ridges are divided into two, so that the deformation of one of the middle and the high portions is hard to affect the other.鬲 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 【 And become a single package of individual packaging. In the article including the absorbent body having the middle-high portion as described above, if the ridge portion is formed, for example, over the entire length direction, when the single-pack product is folded in the surface direction in the longitudinal direction, the deformation is concentrated at the crease position. The situation that leads to strong deformation. When the individual packaged product is stretched by opening at the time of use, there is a crease which may cause a feeling of discomfort during wearing, or the part may not be adhered to the skin and may cause a liquid leakage. In the case where the pleats are provided on both sides of the absorbent article, the pleated portion is also deformed by the folding, and as a result, the leakproof property is impaired. Further, when the individual packaging of the absorbent article having the upper portion of the absorbent body as described above is performed, for example, in a state of being three-folded, the portions protruding in the center of the absorbent body collide with each other. overlapping. As a result, a single package which becomes a part of the overlap becomes thicker and the volume of the central expansion increases. Therefore, it is inconvenient to carry out when carrying out, or when the y is carried, the docking state is broken and becomes a deformed absorbent article, which makes the absorption and wearing feeling worse, or the packaging is deformed during sales and it is difficult to carry out the single packaging. Secondary packaging of the body. The present invention has been made in view of the above aspects, and a first object thereof is to provide a single package of an absorbent article which is tightly folded and which suppresses creases remaining when it is opened for stretching, and is also difficult to form a pleat shape on the side portions. Damaged, the three-dimensional shape of the absorber and its peripheral members can be well maintained. Further, a second object of the present invention is to provide a single package of an absorbent article which enhances adhesion to the body or leaks by forming a protrusion 144019.doc 201023839 which constitutes a mid-high portion on the absorbent body. Sexuality, and a case where a part of the absorbent article is excessively thick when the absorbent article is folded is suppressed. [Technical means for solving the problem] The above first object is achieved by a single package of the absorbent article, which comprises a front sheet on the skin contact side and a non-skin contact side. The back sheet and the absorbent body sandwiched between the two sheets are folded together with the packaging material in the longitudinal direction of the user, and the absorbent body is embossed toward the skin contacting side. The front side high-absorbent portion and the rear middle-high-absorbent portion are formed with a rigid region in the absorber portion between the two high-absorbent portions, and the rigid region is configured to include a concave portion formed by compressing and joining the front sheet and the absorber. In the case where a line extending through the rigid region in the width direction is drawn, a certain portion of the concave portion is present on the line, and the absorbent article is folded at a position where the rigid region is bent. (Hereinafter, the individual package of the absorbent article is referred to as the first embodiment of the present invention). The above first object is achieved by a single package of absorbent articles comprising a topsheet, a backsheet and an absorbent body sandwiched between the two sheets. When the article is folded together with the packaging material, the upper absorbent portion and the rear middle high-absorbing portion are raised toward the skin side of the user, and the two high-absorbent portions are disposed apart from each other by the separation region. In the front side of the front side and the back side of the back side, the absorbent article is folded toward the bulging direction of the two middle and high absorption portions at a bending position of the separation area, and the rear middle and high absorption is in the state of the folded 144019.doc 201023839 At least a portion of the portion is located in the above-described separation region (hereinafter, a single package of the absorbent article is referred to as a second embodiment of the present invention). [Effects of the Invention] In the single package of the absorbent article according to the first embodiment of the present invention, it is difficult to leave the crease when the absorbent article packaged in the above-mentioned tightly folded state is opened, and it is difficult to break the crease shape. And better maintain the three-dimensional shape of the peripheral members in the bent position.

A further, the individual package of the absorbent article according to the second embodiment of the present invention has a higher conformability, absorbs excretion liquid, and the like, and absorbs the liquid once it absorbs the upper part of the absorbent body. It is difficult to leak, and it can achieve a comfortable wearing feeling. Further, it is possible to suppress folding and to increase the thickness of the individual when it is individually packaged, and it is excellent in storage property and portability.

Further, in the rigid region 9, the menstrual napkin 1 is folded with the intermediate position in the longitudinal direction as the bending position k1. Further, in the rear side of the article, the position of the groove 12 surrounding the rear end τ of the rear middle high-absorbing portion 1b is folded at the rear side. Thus, the menstrual sanitary napkin of the first embodiment 1-1 is folded at the position of the three crease lines to form a single package, and more details about the folding order and the like will be described later. Fig. 3 is a cross-sectional view showing the ΠI_ΠI line section shown in Fig. 1 in a schematic manner. In the menstrual sanitary napkin 10 of the first embodiment, the upright pleat portion 4 k including the side sheets 4 and bulging and having the side sheets 4 is provided on the surface thereof. As shown in Fig. 3, the side sheet 4 has a double structure in which the outer side sheet 14 and the inner side sheet 15 are adhered to each other. The side sheet 4 is provided with a slack portion in a state in which the menstrual sanitary napkin main body (the front sheet, the back sheet, and the absorbent body) is stretched, and is disposed on the side portion thereof, and the other inner elastic member is disposed in an extended state. . The menstrual sanitary napkin thus constituted is in a state of being bent in a concave shape toward the side of the front sheet when worn, thereby erecting the pleated makeup 144019.doc -11 · 201023839 to the absorbent body 1 The surface of the surface is raised in an ancient ridge, and is formed in an arc shape in a cross-sectional view in the width direction. In the ridge of the uplift, the pleats 4k are sandwiched between the outer sheet 14 and the inner sheet 15 and extend along the length direction of the worms + / . ], and the plurality of strips are thin and tight (four). From the contraction force, it is ensured that the pleated erecting state is 'up' and a cylindrical shape indicating good cushioning property is maintained in a duct shape along the longitudinal direction of the article. Along the county of the side sheet 4, the base portion 17 of the long and direction-side is disposed on the side sheet 2 on the side of the side of the side of the absorbent body 1, and the base end portion 18 of the other side is fixed away from the absorption. The flap portion 3a that protrudes to the side of the back sheet #3 on the side edge of i. According to this configuration, the first cavity portion Q that extends toward the surface of the absorber 1 is formed inside the side sheet 4, and communicates with the first cavity portion Q1 to the absorber. The second hole portion Q2 extending laterally. It is preferable that the unique cylindrical pleat structure can improve the wearing feeling at the time of wearing and exhibit a high leakage preventing function on the side. Next, referring to Fig. 4 and Figs. 5(a) to 5(c) in which the menstrual sanitary napkin of the present embodiment M is further patterned, reference is made to Figs. 6 and 7(a) and (for comparison of the embodiments for comparison). b) A description will be given of the irregularity of the rigid region portion in the present invention. First, as shown in FIG. 4 and FIG. 5( a ), in the present embodiment, the front middle middle high absorption portion 1a and the rear middle high absorption portion 1b are formed to have an overall width along the longitudinal direction (X direction). The recessed portion 19 of the crescent shape (chord shape) is formed with a rigid region 9 having a lower flexibility than the other portions of the absorbent body. In the present invention, the "rigid region" refers not only to the embossed portion where the bending rigidity is improved, but also to the shape of the plane as a function of the shape, and the crease adhesion which can be obtained with high rigidity can be obtained by folding the surface with respect to I440I9.doc • 12· 201023839 The range of suppression effects. At this time, when the width direction penetrates the line h of the rigid region 9, the portion of the recess 19 is necessarily present on the coil. Specifically, it is approximated that the area projected by the projection image at the time of projection through the rigid portion of the ridge is observed from the direction of the width direction of the article and the direction of the longitudinal direction. As described in the first embodiment, the region (rectangular region) which is separated from the embossed portion of the crescent moon by a point line in the center of the object W is the rigid region 9 (see Fig. 4). The method of forming the concave portion (embossed portion) 19 constituting the rigid region 9 is not particularly limited, and can be formed, for example, by a heat embossing method as follows. That is, the following heat embossing apparatus ′ is used, and includes an embossing roll having a ridge portion having a shape corresponding to the indented portion on the circumferential surface, and a receiving roller disposed opposite to the circumferential surface of the embossing roll. The absorbent body and the front sheet were inserted between the two rolls in such a manner that the side of the front sheet was on the side of the embossing roll. Further, by integrally heating and pressurizing these, an indentation portion having a concave shape in a concave shape is formed. Further, in addition to the thermal embossing method, it may be formed by an ultrasonic embossing method or the like. The embossed portion may be formed into various shapes in addition to these, but this portion will be further described below. When the absorbent article 10 is partially folded in such a rigid region 9 having a certain lengthwise width w, the portion of the rigid region 9 is not bent into a line shape, but is a rigid region 9 as shown in Fig. 5(b). It is bent into a bent portion in a planar shape or a gently curved shape, and it is difficult to form an acute angle crease. Thereby, it is possible to make it difficult to concentrate the strain ε inside the absorber at the time of bending at the bending position. Therefore, when opened during use, irregular or deep creases will not adhere to the 144019.doc •13- 201023839 absorber l, so it is better. x, the lateral cylindrical pleats 4k also have a cylindrical shape as shown in Fig. 5(c), and the hollow shape is ensured. In contrast, when a rigid region is not formed between the front high-absorption portion 1a and the rear middle-high-absorption portion 1b as a form to be compared, as shown in FIG. 7(a), the bending position is easy when bent. It is bent in a linear shape to an acute angle or is easily formed into a crease-like crease at its periphery. Therefore, the strain ε is concentrated from the both sides to the curved portion, and a wrinkled or concave ice-like crease is likely to remain in the central portion 21 (see Fig. 6) of the bending position of the absorbent body at the time of opening. Further, the tubular pleats 4k are also deformed at the bent position in the side, and the hollow portion is partially broken as shown in Fig. 7(b), and it is difficult to secure the original shape. Next, a pre-package state of a single package (embodiment 丨_2) of an absorbent article which is another preferred embodiment of the first embodiment of the present invention will be described with reference to Figs. 8 to 10 . The menstrual sanitary napkin 20 of the present embodiment 1-2 is described with respect to the menstrual period of the above-described embodiment. The same points are omitted, and the point which is not specifically described is appropriately applied. Description of the above menstrual sanitary napkins. The menstrual sanitary napkin 20 includes, along the longitudinal direction thereof, a discharge portion opposing portion A that is disposed at a portion of the liquid discharge portion that is disposed opposite to the wearer when worn, and is disposed on the wearer's portion when the wearing portion is worn. The back side (rear) rear side portion B' and the front end portion c and the rear end portion D of the front end portion and the rear end portion of the sanitary napkin 20, respectively. In the present embodiment, the boundary between the opposing portion a and the rear portion 6 of the excretory portion is present at a substantially central portion in the longitudinal direction of the sanitary napkin 20. Sanitary cotton 2〇144019.doc • 14· 201023839 After the middle part B is separated from the base end portion 81 of the wing end of the sanitary napkin (see Fig. 8) by more than 2 Cm, preferably more than 3 cm apart . In the present embodiment, the rising pleats (leakage preventing walls) 4k extend along both sides in the width direction of the sanitary napkin 2, and the exuding portion opposing portion A includes the inner protruding portion as shown in Fig. 9(a). 42a and the elastically stretchable portion of the outer protruding portion 42b.

At this time, it is integral in the recess 19. Depression, or only indentation depression Alternatively, as in the second embodiment (Fig. 19), irregularities may be formed in the concave portion from the shallower portion and the deeper portion of the concave portion. - Here, the length of the rigid region 9 is the width of your size. Preferably, the thickness of the absorber having no embossing formed around the rigid region, that is, the thickness d (see Fig. 2) of the lower absorbent body lc in the first embodiment of the first embodiment and the first embodiment is 144019. .doc •18- 201023839 ❹

Upper (wherein, in Fig. 2, the lower layer absorber lc is patterned in a thicker manner in consideration of the visibility of the structure of the member structure). Further, the width is preferably 2 to 5 to 9 times the thickness d, and particularly preferably 3 to 6 times. Further, it is preferable that the width 1 of the rigid region is equal to or larger than the width of the front or rear absorbent portion la, and the lateral width (r of Fig. 4). Further, it is preferable to make the lengthwise width b of each indentation larger than the lateral width a (b > a) to ensure effective rigidity. Each of the indentations 19a to 19e is discontinuous when viewed from a projection image when projected in the longitudinal direction (乂 direction) of the menstrual napkin, but as a projection image when projected in the lateral width direction (Y direction), The neighbors are formed in such a way that they are coincident and continuous. Thereby, the whole becomes a crescent moon in a plane view. The rigid region 9 is formed in a region including such a crescent-shaped embossed pattern, whereby when the position of the rigid region 9 is bent, the crease is not made linear, and the pressure of the absorber is not concentrated to the bend. It is preferable that the folded position portion, in particular, does not leave an entangled or concave crease when opened. Fig. 12 is a view showing the shapes of various embossing patterns formed in a rigid region. Further, in the figure, a portion surrounded by a solid line generally indicates a concave portion or an indentation, and a horizontal line or a diagonal line indicates an area thereof. Further, the evaluation result of the actual (four) is shown in the figure. This aspect will be described below. The patterns 8 and 8 shown in the figure are examples of recesses formed by continuous embossing. For such a continuous, the recess and the pressure The pattern has the same meaning. The pattern (10) is an example of a concave portion formed by a discontinuous linear embossing (indentation), that is, a plurality of indentations are collectively formed as a unified concave portion. The lengthwise ratio of each embossed portion The length in the lateral direction is long, and when the ridge is viewed from the lateral direction, the adjacent sides of the linear embossing are overlapped with each other. In the patterns A to G, the bending form is a form in which the surface is 144019.doc -19·201023839. On the other hand, the widths of the respective indentations of the embossed patterns of the patterns 11 and 1 are the lengths in the longitudinal direction, and the bent form is likely to be bent. In this respect, it is difficult for the patterns A to G to be opened. The crease of the residual absorber and the shape of the side member are also stabilized, so it is ideal. Although not shown in the figure, it can also be embossed by combining the embossed patterns. Form a rigid area. For example, Preferably, the pattern 8 to be combined with the reverse pattern "is formed such that the arcuate projecting portions abut against each other, the shape of the embossed portion of" χ "planar view. The individual package of the absorbent article according to the first embodiment is folded and packaged at the three positions of the bending positions ki, k2 and one of the absorbent articles as described above. Fig. 13 is a perspective view showing a single package of the state of the folded package in the order of folding and the state in which it is folded. Further, in Fig. 13, the packaging sheet 34 is indicated by a two-dot chain line, and is partially cut away in Fig. 14 to show it. A packaging sheet 34 including the entire length of the back sheet 3 is attached to the outer surface of the back sheet 3 of the menstrual sanitary napkin 10, and the packaging sheet 34 can be easily removed in use, and after the packaging sheet is removed, the sheet is removed. The adhesive of the material remains on the outer surface of the back sheet 3. Therefore, ©, the back sheet 3 is attached to the undergarment at the time of use. As shown in the figure, the back side contains the absorbent article of the package sheet (4), and the side of the square is shown in the figure! The position of the crease center shown is folded toward the front sheet 2 J, and the side portion 8 is folded toward the front sheet 2 side, and the portion where the crease 2 is folded is at the center of the rigid region 9 The crease line ^ is folded in the same direction to become the state of Fig. 13 (8). At this time, when there is an adhesive surface on the back surface of the side flap portion 8, it may be covered with another packaging sheet. Further, the crease line of 144019.doc •20-201023839 =!== Fig. 1 is folded over the front sheet 2 of the front side f-knife. In a = 'the folded packaging sheet 34 from the sealing portion" is two:::=:: _, can be - raw cotton; = text in the implementation of the form w as an example and the individual packaging shape was thought Second, the case where the kernel is folded into a single package form is the same in the menstrual sanitary napkin of the embodiment 1-2. Furthermore, in this embodiment, a single package folded into four folds is formed, but it is not limited to the above-mentioned folded four folds, and for example, it may be folded in an absorbent article of a type which is longer along the long-term direction and longer. Wrap it up and fold it.

Further, the f-folded position k2 of the shape shown in Fig. U (4) is set to the unfolded rear middle-high absorption portion ib, and the position adjacent to the rear middle-high absorption portion is thereby curved so as to absorb *Mb along the rear middle. Therefore, in the bending position h, there is no crease or deep crease which gives an uncomfortable feeling when the folded absorbent article 1 is opened. Further, a dot-shaped embossed continuous groove 12' is formed. The height of the rear middle-high absorption portion lb is lowered obliquely from the front portion to the rear portion, whereby wrinkles or creases are difficult to form. In the lateral cylindrical pleats 4k, the formation of the rigid region is utilized. In addition to the above-described effects of the strong bending prevention function for preventing the crease formation between the front and rear middle high absorption portions, the effect is also obtained by the cylindrical structure including the standing positions of the inner and outer portions. It is difficult to form wrinkles or creases, and it is difficult to form wrinkles or creases. Further, although the effect is weaker than the creases which are formed by the tubular structure, the elastic portion of the 144019.doc •21 - 201023839 is folded.

Next, a preferred embodiment of the second embodiment of the present invention will be described. Fig. 1 is a schematic view showing a second embodiment of the present invention. A partially broken perspective view of a single package of the menstrual sanitary napkin of the embodiment (Embodiment 21). Fig. 16 is a view schematically showing an absorbent article when the package of the individual package shown in Fig. 15 is taken apart and stretched ( Partially broken perspective view of the menstrual period) (However, the sheet and label for packaging are not shown). The menstrual period cotton of the embodiment 2-1 is on the liquid-impermeable back sheet 3 and the liquid-permeable front side. The sheet 2 has an absorbent body 丨. When the front sheet 2 is brought into contact with the skin of the wearer and the excretion liquid such as menstrual blood is taken, the absorbent body 1 absorbs the excretion liquid or the like that has passed through the front sheet 2 and Keep it. And, in this In the embodiment 2-1, the circumferential embossing 26 and the side embossing 27 are formed so as to integrate the front sheet 2 and the absorbent body 1. Thereby, the front sheet 2 and the absorbent body 1 are not displaced. The method is fixed, and the liquid that escapes to the side and the front-rear direction is blocked, and the liquid is prevented from leaking out. The method of forming the circumferential embossing and the side embossing is not particularly limited, and the method used in such an article can usually be used. Further, in the menstrual sanitary napkin 3 according to the embodiment 2-1, the top sheet 3 and the top sheet 2 are joined by the peripheral seal portion 5 and sealed. In the first embodiment, 'the peripheral seal portion is formed. The method may, for example, be heat-sealed. 144019.doc -22· 201023839 The menstrual period of the 22·1 period of sanitary napkin 3G is in the longitudinal direction of the article=the micro-front ventral side and the sides of the width direction of the article With direction

^Bei ^ Shen out of the wing part 8. When the flap portion 8 is folded into use on the opposite side of the skin side, it is placed on the back side of the panty portion of the undergarment to prevent a movement X, which prevents the stain on the undergarment caused by the side leakage. Although not shown, it is also possible to prevent the side from being erected by the side of the front sheet which is erected so as to be in contact with the skin surface, and the side sheet for forming the raised pleats. Leakage, this aspect is ideal. Further, in the absorbent article 3, an adhesive (not shown) for preventing migration is provided on the inner side of the back surface of the back sheet 3, and is fixedly attached to the position of the abutting state as described above. The absorbent body 1 according to the 2-1st embodiment is disposed such that the peripheral edge of the absorbent article remains in a plane view as substantially the entire surface of the article. The absorbent body 1 includes an inner lower absorbent body lc throughout the circumferential embossing 26 and an upper absorbent body (1&, lb) provided on the lower absorbent body. Here, the lower absorbent body lc is a long strip, and is disposed so as to extend wider from the vicinity of the front end portion l〇c of the article to the vicinity of the rear end portion l〇d. In contrast, the upper layer absorber is included in the front side of the front side of the user, and the high-absorption part (front absorption convex part) la and the back side of the skin side are protruded. Rear absorption convex part) 1 b. In the second embodiment, the upper layer absorber is joined to the lower layer absorber, and the joining method is not particularly limited, but it is preferably joined by a hot melt adhesive or a dot-like unevenness (embossing) treatment. In the 2-1st embodiment, the excretion point G is opposed to the vaginal opening of the 144019.doc • 23-201023839 user in the front middle high-absorbance unit 1a, and the portion is firmly adhered thereto. The skin of the user is in contact. Therefore, when there is excretion liquid (menstrual blood or the like), the liquid discharge liquid is directly absorbed into the front middle high absorption portion 1a via the front sheet 2 and absorbed. Further, since the front middle-high absorption portion 1 & is bulged, the amount of liquid that can be absorbed by the portion is relatively large with respect to the absorber in which the above-mentioned raised portion is not present. Thereby, it can prevent absorption and retention by unintentional diffusion of menstrual blood or the like. In addition, the high-absorption part 1a of the bloodstream and the like are integrated with the lower layer absorption 韹lc, so that the menstrual blood rapidly transitions to the lower layer, for example, even if there is a motion of the user as if it is pressed, the menstrual blood once absorbed may not be absorbed. Waiting for the flow. On the other hand, in the second embodiment, the high-absorption portion 1b is in contact with the buttocks when worn, and particularly in contact with the deeper portion near the anus of the groin. In addition, the rear middle-high-absorption portion 1b is a "barrier wall" that absorbs the liquid which is not absorbed by the front middle-high absorption portion la or which is slightly reversed and turns to the rear side (hip side) to prevent back leakage. In other words, even if there is a liquid flowing out from the front, the front side (barrier surface) H (see FIGS. 17-1 and 18) of the rear middle high absorption portion lb can capture the liquid or the like without causing the liquid flow. To the outside of the article, the rear middle high absorption portion lb or the lower layer absorbent body lc can be quickly introduced. From this point of view, it is preferable that the barrier surface of the rear middle and high absorption portion is a rising surface with respect to the upper surface of the lower absorbent body, and it is preferable that the inclined surface may be inclined or curved. Preferably, a flat surface or a curved surface opposite the front side of the article. For example, there is a situation in which the adhesion between the skin surface of the user in the excretion point G and the surface of the article is damaged or generated due to the movement of the body or the like in the posture of the user lying on his or her side when sleeping. Deviation, or menstrual blood, etc. 144019.doc -24- 201023839 I is more than able to be completely absorbed by the front side of the absorber. At this time, after the sputum is applied, the high-absorption section 1b also exerts the effect of preventing D from leaking blood. When the packaging state of the individual package of the embodiment 2_i is described with reference to Figs. 15 and 16 , the packaging sheet 34 will be on the side of the back sheet 3 of the menstrual napkin 30 and the menstrual napkin 3 〇. Overlap and fold. First, the shoulder sanitary napkin 30 is in the separation zone r, and the rear middle and high absorption section

The baseline 附近 near lb or in contact with the rear middle high absorption portion 1b is bent and folded with the packaging sheet. Further, the curve shown by the baseline 匕 near the front middle high absorption portion 或者 or the vicinity of the front portion 1 〇 c is folded and folded together with the packaging sheet 34 to be folded three times. Further, the edge of the packaging sheet 34 is sealed by the sealing portion 35 to form a single package 100 contained in the menstrual sanitary napkin 30 which is folded three-folded. In the curved packaging sheet 34, the label 33 is attached to the end of the side on which the surface of the individual package 100 is protruded and sealed. When it is opened, the label ^ is pulled in the direction, whereby the packaging sheet 34 of the sealing line 35 is subsequently released, and the label sheet 34 is joined without being peeled off! And the second release paper (not shown) is peeled off together with the packaging sheet 34, so that the sanitary napkin 30 is discharged in a state in which the release paper is peeled off. Figure π-ι shows a cross-sectional view of the 1¥_1¥ line in Figure 16. As shown in the figure, the menstrual sanitary napkin of the present embodiment is provided with a front middle-high absorption portion lb and a rear middle-high absorption portion lb, two convex portions on the entire surface of the layer absorber lc over a substantially uniform thickness. It is set in a separated state across the separation area. Figure 17-2 shows the (4) form W sanitary napkins individually by the surface of the 144019.doc •25-201023839 shown in Figure 17_丨. In the second embodiment, the length of the separation region r in the longitudinal direction is not particularly limited, and the back sheet 3 and the front sheet 2 are omitted. Preferably, it is determined in consideration of the relationship with the length Wb in the longitudinal direction of the rear middle-high absorption portion (see Fig....). For example, it is preferable that the length in the longitudinal direction of the separation region is the length of the rear middle-high absorption portion. 60% or more of the length of the direction ^, more preferably the length Wb or more in the longitudinal direction of the rear middle-high absorption portion lb (w^Wb). When the temperature of the menstrual sanitary napkin of the type of the embodiment 2-1 is Length of the length of the separation zone Read 岐15~5G _, more preferably 2〇~4〇mm. By setting this way, the menstrual napkin 3 will be placed first in the direction of the first tortuous direction Ul (refer to Figure 17_2). The rear middle high absorption portion is located at least in part in the separation region Γ, and the area overlapping with the front middle high absorption portion becomes smaller. Further, 'they are further folded in the second bending direction by the baseline ,, and the space is accommodated in the rear middle and high absorption. The part lb is a single package 1 〇〇' (see Fig. 15) which suppresses a part of the thickened portion. In the menstrual sanitary napkin of the embodiment 2-1, the length of the front middle and high absorption portion ia is Wa in the longitudinal direction. The relationship between the length Wb in the longitudinal direction of the rear middle-high absorption portion 1 b is preferably greater than Wb (Wb < Wa). The length % of the longitudinal direction of the front high-absorbing portion 1a is In view of the function of the liquid or the like in the discharge point G of the convex portion, it is preferably 60 to 120 mm as the sufficient length, and more preferably 70 to 11 inches. For the length of the length direction, consider 144019.doc -26 - 201023839 The function of the barrier wall described above is preferably 2〇~75 mm, more preferably 25~50 mm. By setting the front middle high absorption part la and the rear middle high absorption part lb, it is easy to absorb the excreted menstrual blood, etc. Moreover, it is possible to achieve a conformity and a tight individual package corresponding to the undulation of the user's body. Moreover, the length in the longitudinal direction of the separation region is more than 6 〇% of the rear middle and high absorption portion 丨b. Further, in a preferred form in which the length in the longitudinal direction of the front middle-high absorption portion 1a is longer than the length in the longitudinal direction of the rear middle-high absorption portion 1b, the front middle-high absorption portion 1a is overlapped with the front middle-high absorption portion la of the menstrual period. However, it does not overlap the single package form of the rear middle high absorption portion lb accurately, so that a single package body which is compact and has a more stable package shape can be formed. In the menstrual napkin of the second embodiment, the front middle-high absorption portion u is raised toward the front sheet side at the maximum value and at the height ha (see FIG. 171). On the other hand, the rear middle high absorption portion lb is raised to the front sheet side with a maximum value and a height. The relationship between the above is not particularly limited, but as a method of controlling the bulging, it is preferable that the height of the rear middle and high absorption portion hb < the height of the front middle and high suction φ is 1 ^. By further increasing the height ha of the front middle and high absorption portion, even if the front middle high absorption portion 1a is directly absorbed from the discharge point, it can preferably correspond to the excretion liquid, and when the individual packaging is performed, the folding is performed. After that, the high-intake portion ib is easily located in the space of the separation area! As shown in Fig. 15, the front portion and the rear portion are folded to create an overlapping portion, but in view of portability, it is desirable to form a thin individual package. In order to obtain a thin individual package, the absorbing convex portion may be made thinner, but it is preferable to make the rear convex portion thinner in consideration of the absorption of the front absorbing convex portion corresponding to the excretory portion. 144019.doc •27· 201023839 As described above, first, the excretion fluid absorbed by the front middle-high absorption portion 1a is transferred to the lower layer absorbent body lc and held, and even if there is a liquid which flows into the rear portion, etc., it can be accurately determined by the rear middle-high absorption portion lb. Capture and be absorbed. Further, it is preferable that the two convex portions are applied along the undulation of the body. That's the point. In the sanitary napkin of Yujingtong period, specifically, the height of the front middle and high absorption part is preferably 2.5 to 1 〇 _, more preferably 3 to 8 _. In terms of the height of the rear middle Φ absorbing portion hb, it is preferably 2 to 9 mm, more preferably 2 5 to 7 mm, and the difference between the height of the absorbing portion of the rigid square and the height of the rear middle and high absorbing portion is better. It is 0.5~5 mm, and better is Bu 4 _. At this time, the thickness of the lower absorbent body is preferably from 55 to 6, and more preferably from 2 to 5 Å. Further, in the present invention, the thickness of the absorbent body and the thickness of each of the portions (including the height of the middle and high portions) are determined according to the measurement methods shown in the following examples, unless otherwise specified.

In the second embodiment, in the case of the folding Japanese temple, the rear portion 4 of the rear middle-high absorption portion is overlapped with the rear portion of the front middle-high absorption portion la. In the fourth embodiment, the protrusion height of the rear middle middle high absorption portion ia rear portion t2 is inclined obliquely lower than the front portion k protrusion height in order to suppress the thickness of the overlapping portion as much as possible (see FIG. 17_2). On the other hand, about the rear: High absorption (4) also lowers the height from the front part to the rear part & That is, in the case of folding, the slanted portions are mutually opposed at the time of folding: the square: the upper middle and the high absorbing (four) overlap with the front high absorbing portion a, so that a part of the thickening can be suppressed even if there is an overlapping portion, and If you look at the rear high-absorption section, then the front part is not particularly low 144019.doc -28- 201023839 and can ensure sufficient height, so it constitutes a good barrier. As a method of controlling (lowering) the height of the ridge, a method of controlling the maximum height and a method of controlling the inclination of the overlapping portion have been described, but the method may be used alone or in combination, and the tilt may be only for the rear middle height. The absorbing portion performs processing, and the rear middle-high absorption portion can be enlarged with respect to the inclination angle or the length of the inclination.

In the menstrual sanitary napkin of the second embodiment, a concave portion 19 constituting the hollow portion I9 of the mortar shape is formed in the separation region r. The concave portion 19 has a circular arc shape in plan view, in other words, has a crescent shape or a parabolic shape so as to face the protruding portion toward the front side of the article and the inner side thereof toward the rear of the article. Further, the curved inner side of the arc-shaped recess is placed in contact with the front end of the rear middle-high suction portion lb. Thereby, since the bending rigidity of the portion in which the concave portion 19 is provided is different from that in the periphery thereof, it is easy to be the starting point of the bending, and the rear middle absorbing portion 丨b is not bent, so that it is more accurate to approach the rear middle high absorption portion lb. The position of the square end is folded in such a manner as to be the f curve base ki. In this way, the recess is formed in advance so that the desired portion becomes a curved base line, whereby the high absorption portion is well positioned in the space due to the folding, for example, in the rear of the size, that is, the bending base can be rectified as designed. It is ideal because the position is folded. Further, it is desirable to form the f-curvature base line in the separation region r, whereby the menstrual sanitary napkin 30 does not fold over the high-absorption portion ia^b in the front and rear, and therefore it is difficult to impart the front middle-high absorption portion 13 and the rear middle-high absorption portion. The influence of the crease in the 'is the destruction of the convex part or the residual of the bending when wearing. Further, in the present invention, the "middle-high absorption portion is located in (specific space)", 144019.doc -29-201023839 means that the convex portion does not overlap with other convex portions in a state where the absorbent article is folded. Or the overlap is only a part, so that the main portion of the middle-high absorption portion (preferably, half of it) enters the separation region in which the high-absorption portions are separated from each other in the front and rear sides, and the one surface overlaps with the convex portions. , more inhibit the thickness of this part of the article. It is preferable that the shape of the concave portion 19 is an arc shape as viewed in plan as described above. The arc shape is formed, whereby it is easy to form a bending line which is at least a part of the rear high-absorption portion 1b as the above-mentioned separation region r is accommodated as a base line along the shape of the concave portion 19. Further, as described above, the concave portion 19 is formed along the front end of the rear middle-high absorption portion, thereby enhancing the action of introducing the liquid captured by the barrier surface of the wall portion of the convex portion disposed therein to the lower absorbent body. 'This aspect is ideal. The depth of the recess 19 is preferably such that a sufficient flexibility of the lower layer absorber 1c is obtained. The recess 19 can be formed by a thermal crepe method, for example, as described below. That is, the following heat embossing apparatus is used, i.e., an embossing roll including a ridge portion having a shape corresponding to the concave portion on the circumferential surface, and a nip roller disposed opposite to the circumferential surface of the embossing roll. The photographic and photographic sheets are inserted between the two rolls in such a manner that the side of the front sheet is on the side of the embossing roll. Further, the one body is heated and pressurized to form a recess. Further, it may be formed by an ultrasonic embossing method, a high frequency embossing method or the like in addition to the heat embossing method. Fig. 18 is a cross-sectional view showing the periphery of the recess shown in Fig. 17-1 in an enlarged manner and in a pattern. The absorbent body 1 () having a thickness is disposed on the back sheet 3, and a rear middle high absorption portion lb is formed thereon, and is covered by the front sheet 2. As described above, the concave portion 19 is provided with a curved base line h formed in the width Wd in such a manner as to be close to the rear middle-high absorption portion. 144019.doc • 30· 201023839. The length direction of the recess]9 is preferably 3 to 25 _, more preferably Μ. The length 1d (in Fig. 19) of the width direction of the concave portion is preferably 20 to 5 mm, more preferably 25 to 40 mm. Fig. 19 is a schematic diagram for understanding the arrangement relationship between the planar view shape of the concave portion of the embodiment 2-1 and the lower layer absorbent body 1 c, the medium-high absorption portion 1 a , and the rear middle high absorption portion. The floor plan shown. As described above, the concave portion 19 is curved in an arc shape and includes the protruding portion 19f and the inner portion 19r. The protruding portion 19f is oriented in the forward 1〇c direction, and the curved inner portion 191• is adjacent to the rear middle-high absorption portion 沁. The inside of the recessed portion 19 is formed in a state of being recessed toward the entire periphery thereof, and is formed into a surface shape which is embossed by the embossing process in the region, and is regularly formed at a substantially equal interval in the recess. The (deep) portion l9m (corresponding to the indentations 19a to 19e of the first embodiment) and the higher (lighter) portion 19n. Further, the apex of the embossed convex portion is made lower than the surface of the lower absorbent body. Herein, the folding form of the menstrual sanitary napkin in the individual package of the embodiment 2-1 will be described in more detail. In the menstrual sanitary napkin which is bent at the curved base line in the second embodiment, the rear middle-high absorption portion is in contact with the surface opposite to the front middle-high absorption portion u and is located in the separation region (see Fig. 7.2). On the other hand, in the case where the separation region is not present and the middle and high absorption portions are integrally formed one after the other, the high absorption portions overlap each other in the front and rear at the time of folding, and the thickness of the high absorption portion among the individual packages becomes the middle of the high absorption portion. The thickness ha of the square is approximately ha + hb added to the thickness hb of the rear. Further, for example, 144019.doc -31· 201023839, in a single package of menstrual sanitary napkins in which the middle-high absorption portion is formed from the front ventral side to the rear dorso side, the bending line is disposed on the convex portion anyway, so the middle absorption is high. A bent line is attached to the part to cause deformation, which also adversely affects wearing feeling or absorption. On the other hand, in the second embodiment of the present invention, as will be understood with reference to Fig. 17-2, the thickness of the absorbing convex portion at the time of folding can be made substantially. Further, in the implementation of the state 2-1, the portion which is not on the convex portion is folded, so that the influence of the bend is small. As a result, the wearing feeling when taken out from a single bag body is good, and the absorption and leakage due to the destruction of the absorber can be suppressed. In particular, the front middle-high absorption portion that directly absorbs the menstrual absorption near the excretion point and the barrier portion or the stop portion that leaks as the absorption rear portion are required to function, and then the high-absorption portion is functionally divided. Moreover, each of the convex portions in the front and the rear is disposed separately from the concave portion of the body of the user, and the separated regions in the middle are in a manner of undulating portions along the body of the user. And the configuration, as a whole, can achieve extremely high adhesion to the skin. That is, it is firmly adhered to the desired portion, whereby the desired absorbability can be obtained, and the skin of the user can be softly applied by the cushioning property of the convex portion, and a good wearing feeling can be obtained. . Next, as another preferred embodiment of the second embodiment of the present invention (Embodiment 2-2), there is no single menstrual sanitary napkin having an upper slanting and including a high absorption portion among two substantially rectangular parallelepiped shapes. The package is described. Figure 20-1 is a cross-sectional view of the menstrual sanitary napkin 4 in Embodiment 2-2, and Figure 20-2 is a schematic view showing the menstrual sanitary napkin shown in Figure 20-1. 144019.doc •32· 201023839 A cross-sectional view of the state at the time of packaging. In Figure 20 2, the two mid-high absorption portions la, lb are completely non-coincident, and lb is completely located in the separation region. Thereby, the thickness of the convex portion of the absorbent body at the time of folding can be set to substantially ha even if the shape of the upper side is not present. In Figs. 20-1 and 20-2, the embodiment in which the absorbing portions do not overlap each other during folding is shown. However, the following configuration may be appropriately employed. That is, at least a part of the rear middle high absorbing portion 1 b is located in the separated region. It is sufficient in r, and 'one of the middle and high absorption parts overlaps when it is folded as needed in consideration of absorption performance and the like. 0, ^ The individual package of the absorbent article according to the second embodiment of the present invention is not limited to the above embodiments, and may be a suitable combination of the structures, or may be a constructor different therefrom. . For example, it is also possible to change the front middle high absorption portion and the rear middle high absorption portion in consideration of the susceptibility to the skin and the leakage prevention. For example, in the above-described embodiment 2-1, the front middle high absorption portion is formed into a rectangular shape, and the rear middle high absorption portion is formed. The rear portion 1〇d of the article is formed into a trapezoid having a narrow tip end (see FIGS. 16 and 19), and is easily attached to the human body, and the square φ surface is preferable. In this case, it is preferred that the width of the bottom side of the high absorption portion in the trapezoidal rear side is wider than the front middle high absorption portion. Further, it is also possible to adopt a triangular or rectangular shape in which the rear middle and south absorbing portions are triangular. Furthermore, it is preferable to select a shape in which the front middle high-absorbent portion and the rear middle-high-absorbent portion are viewed in a plan view, and to form an embodiment in which the two are fitted in the plane direction when folded in a single package.
