FIG. 3B is a cross-sectional structure of a portion A in FIG. 3A, and shows a cross-sectional structure of a portion of the diaper 10 including the back sheet 12. As shown in FIG. 3 (b), from the outer surface to the inner side of the diaper 10, in part A, the first exterior sheet 11A, the second exterior sheet 11B, the back sheet 12, the absorber 13, and the top sheet 14 overlap in order.

FIG. 3C is a cross-sectional structure of a portion B in FIG. 3A, and shows a cross-sectional structure of a portion of the diaper 10 that does not include the back sheet 12. As shown in FIG. 3C, the first exterior sheet 11 A, the second exterior sheet 11 B, and the side sheet 18 overlap in order from the outer surface of the diaper 10 toward the inside.

As shown in FIG. 3B, the first exterior sheet 11 A includes an outermost surface 21 that is an outermost surface of the diaper 10, and includes a back surface 22 as a surface other than the outermost surface 21. On the back surface 22, a handling information display unit 23 for displaying handling information that is information relating to handling of the diaper 10 is located. The handling information includes, for example, the size of the diaper 10, the front and back of the diaper 10, the name of the manufacturer of the diaper 10, the brand name of the diaper 10, the type such as a thick type and a thin type, and is required for handling the diaper 10. Information.

The handling information display unit 23 displays handling information about the diaper 10 using characters, symbols, simple figures, and the like. For example, when the handling information display unit 23 is solidified ink positioned on the back surface 22, the left and right sides are mirrored so that the back surface 22 is a mirror surface so that characters or the like as handling information can be correctly viewed when viewed from the outside of the diaper 10. Inverted characters and the like are printed on the back surface 22. In the present embodiment, as the handling information display unit 23, a character string “back” that is an index indicating the front and back of the diaper 10 and a character “M” that is an index indicating the size of the diaper 10 are printed on the back side. 22 is formed. In addition, the parameter | index which shows the back and front of the diaper 10 may be symbols, such as an arrow and a triangle, besides a character string.

The portion of the first exterior sheet 11A located outside the handling information display unit 23 and overlapping the handling information display unit 23 is light transmissive. The light transmittance of the first exterior sheet 11 A allows the handling information display unit 23 located on the back surface 22 to transmit external light and reflects the reflected light reflected by the handling information display unit 23 to a visible level. It is a function.

Specifically, the total light transmittance of the first exterior sheet 11A is 65% or more and 99% or less, so that the first exterior sheet 11A can protect the back sheet 12, the handling information display unit 23, and the like. However, the characters and figures constituting the handling information are made visible through the outermost surface 21. Here, “total light transmittance” is a value measured by a measurement method in accordance with JIS K 7361-1 (Plastic—Testing method for total light transmittance of transparent materials—Part 1: Single beam method). is there. When the total light transmittance is 99% or less, the back sheet 12 and the handling information display unit 23 are protected from rubbing with other members. Further, when the total light transmittance is 65% or more, the handling information displayed on the handling information display unit 23 can be visually recognized from the outermost surface 21.

In addition, the diaper 10 often has a large pattern of characters or the like printed on the back body 10R. The handling information display unit 23 is composed of characters, symbols, and the like with respect to the character design, and needs to be visible to the extent that the user can grasp the meaning. For this reason, in the present embodiment, the total light transmittance of the first exterior sheet 11A is set to be higher than that in the case of only a pattern such as a character.

Here, FIG. 4 shows the relationship between the fiber diameter [denier] and the total light transmittance of various nonwoven fabrics used for the first exterior sheet 11A. In addition, in FIG. 4, the average value which measured 10 points | pieces with the haze meter about each nonwoven fabric is plotted.

As shown in FIG. 4, the total light transmittance in the nonwoven fabric is 65% or more and 99% or less by selecting the fiber diameter [denier] of the nonwoven fabric in an appropriate range. In addition, the total light transmittance of the nonwoven fabric becomes 65% or more and 99% or less even when a filler such as basis weight or titanium oxide is added to the nonwoven fabric.

Note that the exterior sheet 11, particularly the first exterior sheet 11 A, is a member that a handler handling the diaper 10 contacts from the outside of the diaper 10. The touch with respect to 11 A of 1st exterior sheets is so favorable that a fiber diameter [denier] is small. On the other hand, the first exterior sheet 11A is also a member through which handling information is visually recognized. The total light transmittance in the first exterior sheet 11A is higher as the fiber diameter is larger. Thus, when the touch is improved, the visibility of the handling information is lowered, and conversely, from the trade-off relationship that the visibility of the handling information is increased when the touch is lowered, both the touch and the visibility are The fiber diameter [denier], basis weight, amount of filler, and the like are appropriately set so as to be better than those required for each.

The fiber diameter is preferably 0.5 or more and 1.2 or less. The basis weight is preferably 16 g / m ² or less.
As shown in FIG. 5A, the diaper 10 includes a first crease line 26 and a second crease line 27, which are crease lines substantially parallel to the joint 10J. The first crease line 26 and the second crease line 27 are located between the two joint portions 10J and sandwich the handling information display portion 23. The handling information display unit 23 is located between the first crease line 26 and the second crease line 27 and is substantially in the middle of the rear body 10R. The diaper 10 is arranged so that the two joints 10J come close to each other along the first crease line 26 and the second crease line 27, and the handling information display part 23 and the joint 10J do not overlap. Folded.

The diaper 10 has a third crease line 28. The third crease line 28 extends in a direction orthogonal to the length direction of the first exterior sheet 11A, and connects substantially upper ends of the two leg-opening end portions 10L. The handling information display unit 23 is positioned on the waist opening end 10 W side with respect to the third crease line 28. The diaper 10 is folded by, for example, two folds along the third fold line 28 so that the handling information display unit 23 is positioned in the vicinity of the bent portion.

As shown in FIG.5 (b), the diaper 10 folded along the 1st crease line 26, the 2nd crease line 27, and the 3rd crease line 28 is piled up in this state, and the package at the time of shipment It is stored in. Moreover, the diaper 10 is accommodated in the storage body at the time of storage after it is taken out from the package, and the diaper 10 is stored in a folded state even at the time of such storage. In the state stored in the package or the storage body, the position of the handling information display unit 23 is in the vicinity of the bent portion along the third fold line 28, and the folded diapers 10 are stacked. Even if it exists, the handling information is visible from the outside.

In addition, the folding style in the diaper 10 is appropriately set depending on the size of the package in which the diaper 10 is accommodated. The positions of the first fold line 26, the second crease line 27, and the position of the third crease line 28 are set according to the folding mode. The position of the handling information display unit 23 is set to a part where handling information can be visually recognized in the folded diaper 10. Moreover, the position of the handling information display part 23 is determined in the site | part from which handling information can be visually recognized in the state which the several diaper 10 of the folded state was piled up.

[Test example]
The total light transmittance of various nonwoven fabrics that can be used for each of the first exterior sheet 11A and the second exterior sheet 11B is shown for each type of nonwoven fabric. Each nonwoven fabric from Test Example 1 to Test Example 4 is formed by the spunbond method. Each fiber of Test Examples 1 and 2 is a flexible resin, and each fiber of Test Examples 3 and 4 is a PP (polypropylene) resin. Further, Test Example 1 has a basis weight of 16 g / m ² , and Test Examples 2 to 4 have a basis weight of 17 g / m ² .

As shown in Table 1, the total light transmittance of Test Example 1 to Test Example 4 is 65% or more as a single nonwoven fabric. From the result of the total light transmittance, for example, the handling information display unit 23 is formed as a printed matter on the film of the absorber 13, and any one nonwoven fabric of Test Example 1 to Test Example 4 is formed on the handling information display unit 23. The handling information can be made sufficiently visible even if it is disposed on the screen.

Next, Table 2 shows the total light transmittance of a laminate composed of two nonwoven fabrics obtained by superimposing each nonwoven fabric of Test Examples 3 and 4 on each nonwoven fabric of Test Examples 1 and 2.

As shown in Table 2, the total light transmittance of the laminates of Test Example 1 and Test Example 4 is less than 65%. In the display of the handling information through this laminate, the handling information is visually recognized. It was confirmed that it was difficult. In contrast, the total light transmittance of the laminate of Test Example 1 and Test Example 3, the total light transmittance of the laminate of Test Example 2 and Test Example 3, and Test Example 2 and Test Example 4 The total light transmittance of each of the laminates was 65% or more, and it was confirmed that the handling information was sufficiently visually recognized in the display of handling information through these laminates.

From the result of the total light transmittance in these laminates, for example, even if the handling information is printed on the surface facing the back sheet 12 in the second exterior sheet 11B, the total light transmittance of the laminate is If it is 65% or more, the handling information can be made sufficiently visible.

The handling information display part 23 is printed using the inkjet printer with respect to the back surface 22 of 11 A of 1st exterior sheets unwound from the original fabric, for example. By using an inkjet printer for printing, the contents of the handling information display unit 23 can be easily changed. The diaper 10 bonds the first exterior sheet 11A, the second exterior sheet 11B, and the back sheet 12 with an adhesive such as a hot melt adhesive. Further, the back sheet 12 is joined via an absorber 13 wrapped with a core wrap 15 via a top sheet 14.

And since the total light transmittance of the 1st exterior sheet 11A which covers the outside of handling information display part 23 is 65% or more and 99% or less, it is possible to make handling information visible through outermost surface 21. Such visibility is protected by the first exterior sheet 11A from the state in which the diaper 10 is accommodated in the package until the use of the diaper 10 is started.

As mentioned above, according to the said embodiment, the effect enumerated below can be acquired.
(1) Since the handling information display unit 23 is visible through the first exterior sheet 11A and the outside of the handling information display unit 23 is physically protected by the first exterior sheet 11A, the diaper 10 is used. It is possible to prevent the handling information display unit 23 included in the front from being easily viewed.

(2) Since there is one sheet element located outside the handling information display unit 23, the visibility of the handling information can be improved compared to a configuration in which there are two or more such sheet elements.
(3) Since the handling information display unit 23 is located between the first exterior sheet 11A and the back sheet 12, the handling information display unit 23 does not directly touch the wearer's skin. Therefore, for example, the color of the handling information can be darkened, and the handling information display unit 23 can be visually recognized more clearly.

(4) The handling information display unit 23 is printed using an ink jet printer. Therefore, characters, symbols, and the like of the handling information display unit 23 can be formed simply by creating them with an information processing apparatus and outputting them to an ink jet printer, and the contents can be easily changed.

(5) The handling information display unit 23 is disposed at a position where the diaper 10 is folded, and further, the folded diaper 10 is overlaid and visible from the outside. Therefore, even when the diaper 10 is stored in the package at the time of shipment or the storage at the time of storage, the handling information display unit 23 can be visually recognized.

In addition, the said embodiment can also be suitably changed and implemented as follows.
[Variation 1: Position of handling information display section]
As shown in FIG. 6A, the position of the handling information display unit 23 may be arranged along the bent portion of the crotch 10C instead of the back body 10R.
