Description

  The present invention relates to an absorbent article such as a disposable diaper.

  Absorbent articles such as disposable diapers and sanitary napkins are generally packaged and sold after being folded and compressed in a folded state. When a user takes out an absorbent article from the packaging structure packaged in this way, it is difficult to take out one by one.

  For example, Patent Document 1 describes a disposable diaper in which different colors, prints, graphics, and the like are applied to the abdomen side portion located on the abdomen side of the wearer and the dorsal side portion located on the dorsal side at the time of wearing. Has been. Moreover, for example, Patent Document 2 describes a disposable diaper in which different figure prints are formed in a front body region and a back body region. According to the disposable diapers described in Patent Documents 1 and 2, the abdominal side (front body) and the back side (rear body) can be easily distinguished.

  However, in a packaging structure in which disposable diapers are packaged, in general, a plurality of sheets are stacked in a folded state so that the crotch part of the folded disposable diaper can be seen at the outlet. Therefore, even if colors, printing, graphics, etc. are applied to the abdominal side (front body) and back side (rear body), it is not related to the take-out property and it is difficult to take out one by one.

  For example, Patent Document 3 describes a disposable diaper in which a display unit in which characters, graphic prints, and the like are formed is formed on the outer surface of a folded diaper main body. According to the disposable diaper described in Patent Document 3, in the packaged packaging structure, the display unit can be recognized from the outlet.

The print 8a is printed, and the print 8b is printed in a region closer to the back side B than the center line extending in the lateral direction (X direction) of the diaper 1A. In the diaper 1 </ b> A, the print 8 a and the print 8 b can be visually recognized from the back sheet 3 side through the nonwoven fabric 32 of the back sheet 3 as shown in FIG. 1.

  The print 8a and the print 8b are different from each other as shown in FIG. Here, printing means including a pattern and a design image. A pattern is a pattern formed from a plurality of regularly printed figures and the color of the figure. When each minute figure is printed regularly and viewed macroscopically, It also includes the pattern that is. The different printing means that when one of the printing 8a and printing 8b is a pattern and the other is a design image, when one design image of the printing 8a and printing 8b is different from the other design image, the printing 8a and printing. It means that one pattern of 8b is different from the other pattern. Here, “the pattern is different” means that (a) the shape (shape / size) of each figure forming the print is different, (b) the shape of each figure forming the print is Even if they are the same, the arrangement positions are different, and (c) even if the shapes of the individual figures forming the print are the same, including the case where the colors are different. is there. Hereinafter, these will be specifically described with examples.

(A) When the shapes (shape / size) of the individual figures forming the print are different For example, the print 8a shown in FIG. 1 has a blue star-shaped figure in the vertical direction (Y direction) and In the horizontal direction (X direction), they are uniformly distributed at equal intervals. The star-shaped print 8a shown in FIG. 1 has an area of about 5 cm ² and is arranged in 4 rows and 4 columns in each of the vertical direction (Y direction) and the horizontal direction (X direction).
On the other hand, the print 8b shown in FIG. 1 is arranged in such a manner that blue perfect circles are uniformly distributed in the vertical direction (Y direction) and the horizontal direction (X direction) at equal intervals. Is formed. 1 has an area of about 5 cm ² and is arranged in 4 rows and 4 columns in each of the vertical direction (Y direction) and the horizontal direction (X direction).
In this way, the print 8a and the print 8b shown in FIG. 1 are different in the shape of the star-shaped figure forming the print 8a and the shape of the perfect circle-shaped figure forming the print 8b. It is an example.

In addition, for example, in the printing 8a shown in FIG. 4A, a blue perfect circle shape is uniformly distributed in the vertical direction (Y direction) and the horizontal direction (X direction) at equal intervals. Are arranged and formed. The perfect circle-shaped print 8a shown in FIG. 4A has an area of about 0.05 cm ² .
On the other hand, in the print 8b shown in FIG. 4A, blue perfect circle shapes are uniformly distributed in a staggered manner in the vertical direction (Y direction) and the horizontal direction (X direction). Is formed. The perfect circular print 8b shown in FIG. 4A has an area of about 0.3 cm ² .
In this way, the printing 8a and the printing 8b shown in FIG. 4A are different from each other in the size of the perfect circle shape forming the printing 8a and the size of the perfect circle shape forming the printing 8b. This is an example of a different pattern.

(B) Even if the shapes of the individual figures forming the print are the same, the arrangement positions thereof are different. For example, the print 8a shown in FIG. In the vertical direction (Y direction) and the horizontal direction (X direction), they are formed in a staggered manner and uniformly distributed. The perfect circular print 8a shown in FIG. 4B has an area of about 5 cm ² .
On the other hand, the print 8b shown in FIG. 4 (b) is a blue circular figure in 4 rows and 4 columns at equal intervals in the vertical direction (Y direction) and the horizontal direction (X direction). It is uniformly distributed and formed. The area of the perfect circular print 8b shown in FIG. 4B is the same as the area of the print 8a.
As described above, the print 8a and the print 8b shown in FIG. 4B have the shape and size of the perfect circle figure forming the print 8a and the perfect circle figure forming the print 8b. Although it is the same, the arrangement position is different and the pattern is different.

(C) Even if the shapes of the individual figures forming the print are the same, the colors are different. For example, the print 8a shown in FIG. It is densely arranged in the (Y direction) and the horizontal direction (X direction), and is formed in a solid coating shape.
On the other hand, the print 8b shown in FIG. 4C has a solid red pattern in which small red figures are densely arranged in the vertical direction (Y direction) and the horizontal direction (X direction). .
In this way, the print 8a and the print 8b shown in FIG. 4C are the same in the figure that forms the print 8a and the figure that forms the print 8b, but the solid paint color is different and the pattern is different. This is a different example.

Here, “the colors are different” means a color difference that a person can sufficiently recognize visually.
When calculating the color difference, the ΔE ^* value in the “L * a * b * color system” defined in JIS-Z-8729 is used. Here, ΔE ^* is a value obtained by the following formula (1).

ΔE ^* = [(ΔL ^* ) ² + (Δa ^* ) ² + (Δb ^* ) ² ] ^1/2 (1)
(ΔL ^* , Δa ^* , Δb ^* are differences between L ^* value, a ^* value, and b ^* value between two colors. For example, ΔL
^* Is calculated by ΔL ^* = L ^* ₂₋ L ^* ₁ . )

Therefore, it is preferable that the ΔE ^* value is 8 or more for a color difference that can be sufficiently visually recognized by a person, that is, a different color.
In the “L ^* a ^* b ^* color system”, L ^* indicates brightness, a ^* and b ^* indicate color directions, a ^* is approximately red, −a ^* is approximately green, and b ^{* Indicates} a substantially yellow direction, and -b ^* indicates a substantially blue direction. These values can be obtained by using a simple spectral color difference meter NF333 (trade name) manufactured by Nippon Denshoku Industries Co., Ltd.
In the measurement method using the simple spectral color difference meter NF333, a ND120 sensor having a diameter of 8 mm is attached and measured by a stapler type.
The different colors are preferably complementary colors from the viewpoint of visibility.

Further, as shown in FIG. 1, the diaper 1A has both side edges along the longitudinal direction (Y direction) in the crotch part C of the absorbent main body 5 when the developed absorbent main body 5 is viewed from the back sheet 3 side. A mark print 9 is arranged in each of the parts 5s1. The unfolded state refers to a state in which the diaper 1A is stretched in the longitudinal direction and the width direction, and an elastic member disposed on the diaper is stretched. The side edge portion 5s1 means a portion located at an outer edge portion in the lateral direction (X direction) in the side portion 5s of the absorbent main body 5. In the diaper 1A, the mark print 9 is a rectangular figure that is long in the horizontal direction (X direction) as shown in FIG. In the diaper 1A, the mark printing 9 is printed on the non-skin facing surface of the resin film 31 of the back sheet 3 as shown in FIG. And can be seen. Mark printing 9, from the viewpoint of visibility, the size is preferably at 0.3 cm ² or more 5 cm ² or less, and more preferably 1.0 cm ² or more 3.0 cm ² or less. When the diaper 1A is in a natural state (a state in which the elastic member is contracted and a ridge is formed), the elastic member of the crotch portion C arranged to cut the mark print 9 is contracted together with the fixed sheet. Thus, since the wrinkles are formed, the mark print 9 is not visible at all or partially visible when viewed from the back side in this state.

As shown in FIG. 3, the diaper 1 </ b> A is visually recognized from the back sheet 3 side when the crotch C is folded at the crotch C so that the abdomen A and the back B overlap. The folding region 10 is formed with a folded portion ventral region 10a near the abdominal side A and a folded portion back side region 10b near the back side B. The folding region 10 in the present invention refers to the crotch part C of an absorbent article (disposable diaper) in a folded state that can be seen from the opening when the package is opened with the disposable diaper stored in the package. The length in the lateral direction is 0.5 to 2 cm, and the length in the longitudinal direction is equal to the width of the crotch part of the absorbent article. These dimensions are based on the assumption that they are packaged, and they are sandwiched from the abdomen and the dorsal side with acrylic plates (15 x 30 cm) in a folded diaper of a single absorbent article. It is obtained by measuring the folded area when a compressive load (package state) of 5 kPa is applied.
Specifically, using a diaper 1A, as shown in FIG. 3, the diaper 1A is an imaginary line IL that connects mark prints 9 arranged on both side edges 5s1, 5s1 of the diaper 1A (see FIG. 1). Is folded in a so-called fold so that the abdominal side A and the back side B of the diaper 1A overlap. Further, in the crotch part C, the outer portion in the width direction (X direction) of the absorbent core 41 whose both side portions are confined inward is skin facing from the non-skin facing surface side with reference to the mark print 9. The diaper 1A is folded inward on the surface side. The folded region 10 means a region where the state of the diaper 1A folded in this way can be visually recognized from the back sheet 3 side of the crotch C. The folded portion ventral region 10 a means a region closer to the ventral portion A than the virtual line IL in the folded region 10, and the folded portion back side region 10 b means the back of the virtual line IL in the folded region 10. It means the area near the side B. The imaginary line IL (see FIG. 1) is formed at the same position as the center line extending in the lateral direction (X direction) in the diaper 1A.

  Since the diaper 1A is folded as described above, the mark printing 9 cannot be visually recognized from the back sheet 3 side when the diaper 1A is folded, as shown in FIG. . Moreover, it is preferable that the mark printing 9 cannot be visually recognized from the back sheet 3 side even when the diaper 1A is worn by the wearer.

  In addition, as shown in FIG. 3, different prints 8 a 1 and 8 b 1 are arranged in the folded portion abdominal region 10 a and the folded portion back region 10 b in the folded portion abdominal region 10 a and the folded portion back region 10 b, respectively. The prints 8a1 and 8b1 are divided at the outer peripheral edge of at least one of the regions 10a and 10b. Here, the outer peripheral edge of the folded portion abdominal region 10a or the folded portion back side region 10b is the crotch so that the skin contact surface side of the back side portion B and the abdominal side portion A of the absorbent article (diaper 1A) face each other. With the portion C folded in two, the portion of the crotch C folded back from the back sheet 3 is viewed externally (back view), and the horizontally long surface (that is, the folding region) is widened in the width direction (X direction). The abdominal side when a vertical bisector extending in the direction is drawn is a folded portion abdominal region 10a, and the back side is a folded portion dorsal region 10b. Contour. More specifically, as described above, the prints 8a and 8b are patterns, and the print 8a arranged on the ventral side A of the diaper 1A is a color other than the white color of the background color of the constituent material described later, for example, It is a pattern formed by uniformly distributing blue star-shaped figures, and the print 8b arranged on the back side B of the diaper 1A is also a color other than white, for example, a blue circular shape This pattern is formed by uniformly dispersing and arranging the figure. Accordingly, when the diaper 1A is folded, as shown in FIG. 3, when viewed from the back sheet 3 side of the crotch C, a part of the print 8a1 of the print 8a is folded in the folded portion abdominal region 10a. It is divided at the outer peripheral edge of the part stomach side region 10a, and in the folded back side region 10b, a part of the print 8b print 8b1 is divided at the outer peripheral edge of the folded part back side region 10b, and is printed differently. . In other words, the print 8a1 in which a plurality of star-shaped figures are arranged in the horizontal direction (X direction) is divided and divided at the outer peripheral edge of the folded portion ventral region 10a in the folded portion ventral region 10a. A portion of the print 8a1 in which a plurality of star shapes are arranged in the horizontal direction (X direction) is arranged, and a plurality of perfect circular figures are arranged in the horizontal direction (X direction) in the folded portion back side region 10b. The print 8b1 formed side by side is divided at the outer peripheral edge of the folded back side region 10b, and a part of the print 8a1 in which a plurality of semicircular shapes are arranged in the horizontal direction (X direction) is arranged. A part of 8a1 and a part of printing 8b1 are different from each other.

  Based on the other examples shown in FIG. 4A to FIG. 4C, it is specifically described that different prints 8a1 and 8b1 are arranged in the folded portion ventral region 10a and the folded portion back region 10b. Specifically, the print 8a shown in FIG. 4 (a) is a pattern formed by uniformly distributing blue circular figures, and the print 8b shown in FIG. 4 (a) is blue. It is a pattern formed by arranging perfectly circular figures uniformly staggered. Therefore, when the diaper is folded, as shown in FIG. 5A, when viewed from the back sheet 3 side of the crotch C, the printed portion 8a1 of the print 8a is printed on the folded stomach side region 10a. In other words, a print 8a1 in which a plurality of perfect circle figures are arranged in the horizontal direction (X direction) is arranged, and a print 8b1 that is a part of the print 8b, that is, a print 8b1 of the print 8b, that is, A print 8b1 in which a plurality of perfect circular figures are arranged in the horizontal direction (X direction) is arranged, and the portions located at both ends in the X direction of the print 8b1 are the outer peripheral edges of the folded back side region 10b. The printing 8a1 and a part of the printing 8b1 are different from each other.

  Further, the print 8a shown in FIG. 4B is a pattern formed by uniformly dispersing blue circular figures in a staggered pattern, and the print 8b shown in FIG. It is a pattern formed by arranging perfectly circular figures uniformly dispersed. Accordingly, when the diaper is folded, as shown in FIG. 5 (b), when viewed from the back sheet 3 side of the crotch C, a perfect circle shape is laterally displayed in the folded portion ventral region 10a. The two prints 8a1 formed side by side in the (X direction) are divided at the outer peripheral edge of the folded ventral region 10a, and a part of the print 8a1 in which two semicircular shapes are arranged in the horizontal direction (X direction) is arranged. In the folded portion back side region 10b, a print 8b1 formed by arranging a plurality of perfect circular figures in the horizontal direction (X direction) is divided at the outer peripheral edge of the folded portion back side region 10b. A part of the print 8b1 in which a plurality of circular shapes are arranged in the horizontal direction (X direction) is arranged, and a part of the print 8a1 and a part of the print 8b1 are different from each other.

  Also, the print 8a shown in FIG. 4C is a pattern in which small blue figures are densely arranged and formed in a solid coating shape, and the print 8b shown in FIG. It is a pattern that is densely arranged and formed in a solid paint shape. Therefore, when the diaper is folded, as shown in FIG. 5 (c), when viewed from the back sheet 3 side of the crotch C, the printed portion 8a is printed on the folded portion ventral region 10a. A print 8a1 divided by the outer peripheral edge of 10a, that is, a blue solid print 8a1 is arranged, and the print 8b is divided by the outer peripheral edge of the folded back side area 10b in the folded back side area 10b. A print 8b1, that is, a red solid-colored print 8b1, is arranged, and the print 8a1 and the print 8b1 are colored in mutually different colors to be different prints.

  Further, when the diaper 1A is folded, as shown in FIG. 3, when viewed from the back sheet 3 side of the crotch C, the print 8a1 of the folded stomach side region 10a and the print 8b1 of the folded back side region 10b. Is divided by a plain region 10c that communicates horizontally in the width direction (X direction). Examples of the plain region 10c include a ground color region of the constituent material of the diaper 1A and a region where printing is not performed. It is divided that the plain region 10c has a certain width or more from one end in the width direction of the absorbent article (diaper 1A), and is straight or meandering without being blocked by printing. It means a state in which it is continuously formed without interruption. The certain width or more is 1 mm or more, preferably 3 mm or more from the viewpoint of visibility. The background color of the constituent material will be described. In the diaper 1A, the color of the back sheet 3 that constitutes the diaper 1A, specifically, the color composed of the color of the resin film 31 and the color of the nonwoven fabric 32 is meant. There are many colors of the system, but it is not limited to the white system. In the diaper 1A, the plain region 10c (ground color region) is an imaginary line IL (a center line extending in the horizontal direction (X direction) in the diaper 1A) as shown in FIGS. ) And is formed in a continuous line shape along the virtual line IL. The same applies to the diapers shown in FIGS. 5 (a) to 5 (c). In general, an indicator that informs the presence or absence of urination is arranged in the crotch part of the diaper along a center line CL extending in the vertical direction (Y direction). However, this indicator is not formed by printing. In addition, since it is a linear line having a narrow width, even if an indicator is provided, it is not considered that the continuous line of the plain area 10c (ground color area) is hindered. The background color region 10c formed in a continuous line shape in the horizontal direction (X direction) has a width (length in the Y direction) of 0.5 mm or more and 10 mm from the viewpoint of distinguishability between the print 8a1 and the print 8b1. Or less, more preferably 1.0 mm or more and 3.0 mm or less.

Next, the preferable manufacturing method of diaper 1A is demonstrated, referring FIG.
