  Each panel portion 27 has a substantially rectangular panel body 31 having a longitudinal direction along the longitudinal direction of the absorbent article body 2 and a pair of fastening portions 32 protruding outward from the panel body 31. is doing.

  Each panel body 31 has one side joined to the top sheet 7, the back sheet 8, or between the top sheet 7 and the back sheet 8. Moreover, the edge part of the longitudinal direction of each panel main body 31 is located inward rather than the edge part by the side of the back side part 11 of the absorbent article main body 2. FIG.

  In addition, the fastening portion 32 is provided inward of both side portions of the panel body 31 on the side opposite to the absorbent article body 2 in the longitudinal direction, and is separated from each other in the longitudinal direction of the panel body 31. ing. Furthermore, each fastening part 32 is attached with a hook fastener 33 as a surface fastener, and the hook fastener 33 is a surface disposed on the back surface side of the back sheet 8, that is, on the surface opposite to the absorber 9. The back side portion 11 and the abdominal side portion 13 are locked by being fastened to a horizontally long loop fastener 34 as a fastener.

  The absorbent article body 2 has a pair of color mark portions 36a, 36a, 36b, 36b, 36c, 36c corresponding to the absorbent pads 1a, 1b, 1c (FIG. 2), respectively, on the surface sheet 7 side. It is arrange | positioned so that visual recognition is possible. In addition, these color mark parts 36a-36c represent the difference in coloring by the difference in hatching in drawing for convenience.

  The color mark portions 36a and 36a are formed in, for example, a quadrangular shape, and are colored with a color corresponding to the pad back surface sheet 4a of the absorbent pad 1a (FIG. 2 (a)). It is arranged corresponding to the position where the both side edges in the direction intersect with the both edges in the longitudinal direction, in other words, at least two corners of one end in the longitudinal direction of the absorbent pad 1a. Further, the color mark portions 36 a and 36 a are provided at positions symmetrical with respect to the center line L in the width direction of the absorbent article body 2.

  Similar to the color mark portions 36a and 36a, the color mark portions 36b and 36b are formed, for example, in a quadrangular shape, and are colored and absorbed by a color corresponding to the pad back surface sheet 4b of the absorbent pad 1b (FIG. 2 (b)). Disposed to correspond to the edge of the absorbent pad 1b, that is, the position where the widthwise side edges and the longitudinal edges of the pad intersect, in other words, at least one corner of the absorbent pad 1b in the longitudinal direction. Has been. The color mark portions 36b and 36b are provided at positions symmetrical with respect to the center line L in the width direction of the absorbent article body 2.

  The color mark portions 36c and 36c are formed in, for example, a rectangular shape, like the color mark portions 36a and 36a and the color mark portions 36b and 36b, and correspond to the pad back sheet 4c of the absorbent pad 1c (FIG. 2 (c)). The two edges of the absorbent pad 1c, that is, the positions where the side edges of the absorbent pad 1c cross each other and the both ends of the longitudinal direction, in other words, at least one corner of the absorbent pad 1c in the longitudinal direction. It is arranged corresponding to the part. The color mark portions 36c and 36c are provided at positions symmetrical with respect to the center line L in the width direction of the absorbent article body 2.

  Therefore, the color mark portions 36a to 36c are disposed in the absorbent article main body 2 along the width direction because the longitudinal dimensions of the absorbent pads 1a to 1c (FIG. 2) are the same and the width dimensions are different from each other. . Note that the color mark portions 36a and 36b and the color mark portions 36b and 36c adjacent to each other may be adjacent to each other without a gap as shown in FIG. 1, may overlap each other, or may be separated from each other. .

  Moreover, since the color mark parts 36a-36c are arrange | positioned in the position corresponding to the edge part of the absorbent pads 1a-1c (FIG. 2), the back side part 11, the ventral side part 13, or both However, in the absorbent article main body 2 that is a tape-type outer that is worn by engagement between the hook fastener 33 and the loop fastener 34, it is possible to wear the wearer in the state where the wearer is sleeping. In this case, the absorbent pad 1a to 1c (FIG. 2) which is the inner is first applied to the dorsal side portion 11, and leakage from the dorsal side is generally more frequent than the ventral side. In consideration of the above, it is preferable that the color mark portions 36a to 36c are disposed at least on the back side portion 11.

  Further, as the color mark portions 36a to 36c, a method of directly applying to the surface sheet 7 by printing or hot melt adhesive, or a sheet body such as a colored film or a colored nonwoven fabric is applied to the surface sheet 7 as an adhesive, There are methods such as heat sealing and fixing by ultrasonic waves. For example, in the case where the color mark portions 36a to 36c are formed by fixing the sheet body, rather than fixing the color mark portions 36a to 36c to each, a plurality of color mark portions are formed in advance to form a sheet body, The sheet body is preferably formed by being fixed to the top sheet 7 or the like.

  And, if the color mark portions 36a to 36c are visible from the surface sheet 7 side, the position of the color mark portions 36a to 36c is not particularly limited, but when located on the surface side of the surface sheet 7, There is a possibility that the touch at the time of wearing may be deteriorated, and if the color mark portions 36a to 36c are less conspicuous when located on the back sheet 8 side than the absorbent body 9, for example, the top sheet 7 and the absorbent body 9 It is preferable to dispose at a position other than the surface side of the top sheet 7 such as the back surface of the top sheet 7 or the surface on the absorber 9 side.

  The color mark portions 36a to 36c are preferably the same color as the corresponding pad backsheets 4a to 4c (FIG. 2). However, for example, when the materials and coloring methods are different, the color mark portions 36a to 36c should be exactly the same color. Since it may not be easy, the colors may not necessarily be exactly the same as long as they have substantially the same color, that is, similar colors to the extent that they can be distinguished from combinations of other color mark portions and the back sheet.

Next, the operation of the first related technique will be described.

  In use, in the unfolded state shown in FIG. 1, any one of the absorbent pads 1a to 1c shown in FIGS. 2 (a) to 2 (b) is placed in any of the corresponding color mark portions 36a to 36c. The absorbent article main body 2 is aligned and placed, and the absorbent article main body 2 is appropriately folded and worn on the wearer's crotch, and the hook fastener 33 is pulled on the fastening portion 32 while the hook fastener 33 on the ventral side portion 13 is loop fastener 34. The absorbent article main body 2 is attached by being fastened to.

As described above, according to the first related technique , a pair of color marks that are visible from the surface sheet 7 side corresponding to the edge portions of the plurality of types of absorbent pads 1a to 1c having different sizes. By arranging the portions 36a, 36a, the color mark portions 36b, 36b, and the color mark portions 36c, 36c in different colors, the types of the corresponding absorbent pads 1a to 1c can be easily identified by color. The absorbent pads 1a to 1c can be easily aligned with the mounting positions simply by aligning the corners of the absorbent pads 1a to 1c having different sizes with the corresponding pair of color mark portions 36a to 36c.

  Moreover, compared with the conventional case which provides a mark part in the absorbent pad 1a-1c side, while being able to suppress manufacturing cost, the appearance of the absorbent pads 1a-1c etc. is not deteriorated.

  Furthermore, the absorbent pad can be easily mounted just by aligning the edge of the absorbent pad 1a-1c with the color mark portions 36a-36c of the same color as the pad back sheet 4a-4c of each absorbent pad 1a-1c. Alignment is facilitated, and it is possible to prevent erroneous attachment of different absorbent pads 1a to 1c.

  And since the absorbent pads 1a to 1c are different only in the colors of the pad back sheets 4a to 4c, no special equipment is required at the time of manufacture, and the pad back sheets 4a to 4c that are colored in advance may be used. It doesn't cost more than necessary.

In the first related technique , the width dimensions are equal to each other and the longitudinal dimensions are the same as in the second related technique shown in FIGS. 3, 4 (a), 4 (b), and 4 (c). When different absorbent pads 1a, 1b, and 1c are used, for example, when the longitudinal dimension of the absorbent pad 1a is the shortest and the longitudinal dimension of the absorbent pad 1c is the longest, the color mark portions 36a to 36c are placed on the absorbent article main body. By arranging along the longitudinal direction of 2, it is possible to achieve the same effects as the first related art .

Further, as in the third related art shown in FIGS. 5, 6 (a), 6 (b) and 6 (c), absorbent pads 1a, 1b and 1c having different width dimensions and longitudinal dimensions are provided. When used, for example, when the width dimension and the longitudinal dimension of the absorbent pad 1a are the shortest and the width dimension and the longitudinal dimension of the absorbent pad 1c are the longest, the color mark portions 36a, 36b, 36c are formed on the absorbent article body 2. Inclined with respect to the longitudinal direction and the width direction, respectively, and from the absorbent pad 1a to the absorbent pad 1c, from the center side in the longitudinal direction and the width direction of the absorbent article body 2 to the edge side of the absorbent article body 2 With the arrangement, it is possible to achieve the same operational effects as the above-described related technologies .

Further, in each of the related techniques , as in the first embodiment shown in FIG. 7, the color mark portions 36a to 36c are formed in an area corresponding to the allowable displacement range of the absorbent pads 1a to 1c. It is also possible. That is, although it is desirable that the mounting positions of the absorbent pads 1a to 1c are substantially determined, the ideal mounting positions of the absorbent pads 1a to 1c are not necessarily one point so that the gender and body shape of the wearer vary. Therefore, even if the mounting position is shifted in the longitudinal direction and the width direction, the color mark portions 36a to 36c are set as areas representing the aggregate of the end edge portions within the allowable range. In this case, it is possible to achieve the same effects as the above-mentioned related technologies, and easily attach the edge portions of the absorbent pads 1a to 1c so as to be within the area of the color mark portions 36a to 36c. The mounting position of the absorbent pads 1a to 1c can be prevented from being displaced, and leakage due to this displacement can also be prevented.

And in the said 1st Embodiment, as the 2nd Embodiment shown in FIG. 8, each color mark part 36a-36c is the structure from which the tolerance | permissible_range of the mounting position shift | offset | difference of the absorbent pads 1a-1c differs, That is, a configuration in which the areas of the color mark portions 36a to 36c are different, for example, a configuration in which the area of the color mark portion 36a is the largest and the area of the color mark portion 36c is the smallest is possible.

  In each of the above embodiments, the absorbent pads 1a to 1c are provided with a general anti-slipping means such as an adhesive or a hook fastener for preventing the absorbent pads 1a to 1c from being displaced from the absorbent article main body 2. You may arrange | position in any part of 4a-4c. Preferably, by disposing the displacement prevention means in the vicinity of the edge portion, the edge portions of the absorbent pads 1a to 1c are aligned with the color mark portions 36a to 36c, and the displacement prevention means is adhered, Or since it can be made to engage, position alignment at the time of mounting becomes more reliable and easy.

  Furthermore, the color of the pad back sheets 4a to 4c of the absorbent pads 1a to 1c can be any color as long as they can be distinguished from each other, and the color mark portions 36a to 36c correspond to the respective absorbent pads 1a to 1c. It is appropriately set according to the color of the pad back sheets 4a to 4c of 1c.

  In each of the above embodiments, there are three types of absorbent pads. However, by making the type of the color mark part correspond to the type of the absorbent pad, it is possible to handle two or more types of absorbent pads. Needless to say.
