Description

  The present invention relates to a disposable diaper.

  Some absorbent articles are colored in order to achieve a predetermined purpose. For example, there is a panty liner colored in a certain hue (in the range of 5.7 to 8.7 in the Munsell color system) in order to conceal the color of excrement (see Patent Document 1). Alternatively, there is a disposable diaper in which the color of the pattern and the color before or after the hydrophilic agent is visually changed and the color of the pattern are similar in order to improve the visibility such as discoloration caused by urination (see Patent Document 2). ).

  As an absorbent article, there is a disposable diaper used for low-weight infants whose birth weight is 3000 g or less. Underweight children often spend their lives in incubators in the neonatal intensive care unit (NICU) and recovery unit (GCU) immediately after birth. In the incubator, since only diapers are often worn, the appearance is more important than normal diapers.

  A low-weight child is a child whose childbirth was accelerated due to some kind of influence when it grew up in the mother's womb. In low-weight infants, the skin color tends to be darker than normal newborns due to the effects of metabolism and blood flow.

  In addition, in the case of a low-weight child in an incubator, the priority is given to absolute rest, so the opportunity for the mother to contact is not free. Therefore, in order to promote the motherhood of mothers, it is necessary to make the child feel more cute. Also, some mothers with low-weight children may feel sorry for having a baby earlier than planned, blame themselves, or be depressed. Therefore, disposable diapers for low-weight infants are also required to have an effect of relieving the feelings of such a mentally unstable mother (or a family member who has visited) and giving a sense of security.

  Furthermore, since an environment is created in the incubator to reproduce the mother body (intrauterine), the illuminance is often set to be dark as in the uterus. Therefore, even if the appearance of the disposable diaper is devised, the effect may not be obtained when viewed from outside the incubator. That is, even when a child is in a dim incubator, it is important that the diaper worn when the child is viewed from outside the incubator is easily understood.

  In addition, low-weight children may have unstable body functions and life support functions, and may have bloody stool or hematuria. Therefore, when a strong red or orange color similar to the color of blood is used for a disposable diaper, there is a problem that nurses and the like are likely to misidentify bloody stool or hematuria.

  The present invention has been made in order to solve the above-mentioned problems. The skin color of a low-weight child is shown well, the mother and the like have a sense of security, the visibility is high from outside the incubator, and bloody stool An object of the present invention is to provide a disposable diaper that can reduce the possibility of misperception such as hematuria.

An example of the invention for achieving the above object has a front waistline portion, a rear waistline portion, a crotch portion positioned between the front waistline portion and the rear waistline portion,

The elastic member 27 is formed into a sheet shape by, for example, a stretchable nonwoven fabric, but may be configured by arranging a plurality of rubber threads along the product longitudinal direction L.

  The leg side gathers 16 are three-dimensional gathers for preventing liquid leakage from the gaps in the footsteps. A pair of leg side gathers 16 is formed along the product longitudinal direction L over the front waistline part 3, the crotch part 5, and the back waistline part 7 (refer FIG. 1). The leg side gathers 16 are formed so as to cover both edges of the central strip region 12 inside the side flaps 14.

  The leg side gathers 16 are mainly configured from a portion inside the front seat 26 (see FIGS. 2A to 2C). The inner edge of the front seat 26 of the crotch part 5 is stretchable by thread rubber or the like. The front seat 26 is joined along the product longitudinal direction L at a joining portion 26A between the central strip region 12 and the side flap 14 (thick dotted line in FIG. 1). A region inside the joint portion 26A of the front seat 26 constitutes the leg side gather 16 (three-dimensional gather) with the joint portion 26A as a fulcrum.

  The waist gathers 18 are waistline elastic parts arranged along the product width direction W in the rear waistline part 7 (see FIG. 1). In the back waistline part 7, the waist gather film 28 is arrange | positioned between the absorber 21 and the back seat | sheet 24 (refer FIG. 2C). The waist gather film 28 is a belt-like stretchable member that stretches along the product width direction W. The waist gathers 18 are configured by the waist gather film 28 imparting stretchability to the back sheet 24 and the like. The length of the waist gather film 28 in the width direction W is longer than that of the absorber 21. For this reason, the waist gathers 18 are formed so as to protrude from the absorber 21 to the outside in the product width direction W.

  The fastening tape 30 is attached to the end of the rear waistline portion 7 (side flap 14) in the product width direction W (see FIG. 1). The fastening tape 30 is attached by a part of the fastening tape 30 being sandwiched between the front sheet 26 and the back sheet 24 constituting the side flap 14 (see FIG. 2C).

  As shown in FIG. 3A, the fastening tape 30 can be divided into a proximal end region A, an intermediate region B, a hook sheet region C, and a distal end region D. As shown in FIG. 3B, the fastening tape 30 includes a base sheet 32, a hook sheet 34, and a target sheet 36.

  The proximal end region A is a region joined to the side flap 14. The base end region A is sandwiched between two sheets (a front seat 26 and a back sheet 24) constituting the side flap 14, and both surfaces of the base end region A are joined to the side flap 14. Note that the base end region A may be bonded to the surface on the back side of the side flap 14, and only one surface of the base end region A may be bonded to the side flap 14. Regions other than the base end region A (intermediate region B, hook sheet region C, tip region D) are arranged so as to protrude outward from the side flap 14 of the rear waistline portion 7 in the product width direction W.

  The intermediate region B is a region between the base end region A and the hook sheet region C. The hook sheet area C is an area where the hook sheet 34 is provided, and is an area (engagement area) engaged with the target tape 29. Since there is no hook sheet 34 in the intermediate region B, the bending rigidity of the intermediate region B is smaller than that of the hook region, and the intermediate region B is easy to bend. The tip region D is a region outside the hook sheet 34. The tip region D functions as a “knob” that is picked up with a finger when the fastening tape 30 is attached or detached. In addition, the area | region X of FIG. 3A is an area | region of the side flap 14. FIG. In this embodiment, the length of the fastening tape 30 in the tape width direction (the length of the hook sheet region C in the tape width direction) is longer than the length of the target tape 29 (colored region CE described later) in the product longitudinal direction L. Is also formed short.

  The base sheet 32 is a sheet that becomes a base of the fastening tape 30. The base material sheet 32 is comprised from the sheet | seat which laminated the film on the nonwoven fabric or the nonwoven fabric. Moreover, the base material sheet 32 is comprised by the sheet | seat (sheet which laminated | stacked the film on the nonwoven fabric or the nonwoven fabric) of 1 sheet or multiple sheets. The base sheet 32 is disposed in the entire region from the proximal end region A to the distal end region D of the fastening tape 30.

  The hook sheet 34 is a sheet that engages with the target tape 29. The hook sheet 34 can also be engaged with the other fastening tape 30. A number of engagement hooks (not shown) are provided on the surface of the hook sheet 34 (the surface opposite to the base material sheet 32 side). Is engaged with the target tape 29. The hook sheet 34 is joined to the base sheet 32.

  The target sheet 36 is a sheet that can engage the hook sheet 34 of the other fastening tape 30. The target sheet 36 is composed of a sheet in which one or a plurality of nonwoven fabrics are stacked. The target sheet 36 is bonded to the base sheet 32 on the side opposite to the hook sheet 34.

  The target sheet 36 is disposed at least in the hook sheet region C and the tip region D. The target sheet 36 in the drawing is arranged in a part of the base end area A (part of the base end area A on the intermediate area B side), the intermediate area B, the hook sheet area C, and the front end area D. As described above, when the target sheet 36 is provided from the proximal end region A to the distal end region D and the target sheet 36 is joined to the side flap 14 together with the base sheet 32 in the proximal end region A, the other fastening tape 30 is provided. This is desirable because the target sheet 36 is less likely to be peeled off from the base material sheet 32 at the time of attachment / detachment.

  The target sheet 36 is not provided in a part of the base end area A (a part on the side opposite to the intermediate area B side). A waist gather film 28 (see FIG. 2C) is disposed in an area where the target sheet 36 is not provided. That is, the end portion of the target sheet 36 and the end portion of the waist gather film 28 are sandwiched between the base end region A and the back sheet 24 without overlapping. Thereby, a level | step difference is reduced between the base end area | region A of the base material sheet | seat 32, and the back sheet | seat 24, and it becomes easy to pinch both the target sheet | seat 36 and the waist gather film 28. FIG.

  A target tape 29 is provided on the front waistline portion 3 (see FIG. 1). The target tape 29 is disposed on the back side of the back sheet 24 of the front waistline portion 3 (see FIG. 2A). The target tape 29 is a member that can be engaged with the fastening tape 30 and is formed of a nonwoven fabric. By engaging the fastening tape 30 with the target tape 29 (or a target region E3 described later), the child is allowed to wear the disposable diaper 1.

<Regarding the area of the disposable diaper 1>
4A to 4C and FIG. 5 are developed plan views (views seen from the back side in the thickness direction) of the back surface of the disposable diaper 1. Drawing 6 is a figure which looked at disposable diaper 1 used as a form at the time of wearing from the front (front waist part 3 side). From the back side of the disposable diaper 1, a predetermined pattern printed on the leak-proof sheet 23 or the base sheet 32 can be visually recognized through the back sheet 24 or the target sheet 36. The pattern may be printed directly on the back sheet 24 or the target sheet 36.

  The disposable diaper 1 includes a front region E1, a rear region E2, a target region E3, an underbody region E4, and a fastening tape 30 (region E5. The bold line in FIG. 6 indicates the region E5). Can be divided into Even when the disposable diaper is worn on the child, the front side region E1 is a region that is easy to get into the eyes when the child wearing the disposable diaper 1 is lying on his back because the area hidden by the fastening tape or the like is small. The rear region E2 is the most visible region when looking at a child lying on his / her face down. Moreover, the target area | region E3 is an area | region to watch in order to engage the fastening tape 30, when wearing the disposable diaper 1. FIG. The suspension region E4 is a region that easily enters the eyes because the child moves with the foot when the child moves the foot. Since the fastening tape 30 is a part that is gripped when the disposable diaper 1 is worn on a child, the fastening tape 30 is a part that is easy to watch.

  The front region E1 is on the front waistline 3 side with respect to the center in the product longitudinal direction L, and is closer to the center in the product longitudinal direction L than the target region E3 (see FIG. 4A. The inside of the thick line in FIG. 4A is The front area E1 is shown).

  The rear region E2 is a region on the rear waistline portion 7 side with respect to the center in the product longitudinal direction L, and on the center side in the product longitudinal direction L with respect to the white region WE2 (described later), and does not include the fastening tape 30. (See FIG. 4B. The thick line in FIG. 4B shows the rear region E2.)

  The target area E <b> 3 is provided in the front waistline portion 3 and can engage the fastening tape 30. When the target tape 29 is present as in the present embodiment, the target area E3 is an area corresponding to the target tape 29 (see FIG. 4C. The thick line in FIG. 4C indicates the target area E3). When there is no target tape 29, the target area E3 is a rectangular area including a mark (pattern) for engaging the fastening tape 30 drawn on the disposable diaper 1.

  The suspension region E4 corresponds to a region occupied by the elastic member 27 in the disposable diaper 1 (see FIG. 5, the thick line in FIG. 5 indicates the suspension region E4). When the elastic member 27 has a sheet shape, the underbody region E4 corresponds to a region surrounded by the outer periphery of the sheet. When the elastic member 27 is a plurality of thread rubbers, the underbody region E4 corresponds to a region sandwiched between the innermost thread rubber and the outermost thread rubber. In the present embodiment, the front region E1 and the rear region E2 partially overlap with the underbody region E4.

<About coloring area>
A visible colored region CE is provided in at least one of the front region E1, the rear region E2, the target region E3, the fastening tape 30, and the underbody region E4. The colored region CE is a region colored in a color other than white in a certain region (for example, in the front region E1). The colored region CE forms a pattern of the disposable diaper 1. In the present embodiment, the colored regions CE of the front region E1, the rear region E2, the target region E3, and the underbody region E4 are printed on the leakproof sheet 23. The colored region CE of the fastening tape 30 is printed on the base material sheet 32.

  The front region E1, the rear region E2, and the undercarriage region E4 are mainly provided with a dot-pattern coloring region CE (see FIGS. 4A, 4B, and 5), and the target region E3 has a rectangular coloring region CE. Provided (see FIG. 4C). Further, the fastening tape 30 is provided with a colored region CE along the shape (see FIG. 6).

  4A to 4C are partially different from the pattern in FIG. 5 (arrangement of the colored region CE) and the pattern in FIG. 6 (arrangement of the colored region CE). . For example, in FIG. 5, more colored regions CE in the underbody region E4 are provided than the colored regions CE in the underbody region E4 in FIG. 4A and the like. Moreover, the fastening tape 30 of FIG. 4A-FIG. 4C and FIG. 5 has shown the example in which the coloring area | region CE is not provided. On the other hand, the fastening tape 30 of FIG. 6 is provided with a colored region CE. Further, the coloring region CE is not provided in the target region E3 of FIG.

  The colored region CE includes a first region CE1 colored with a predetermined color and a second region CE2 colored with a color not corresponding to the predetermined color. 4A to 4C, FIG. 5 and FIG. 6, the first region CE1 in each region (the front region E1, the rear region E2, the target region E3, the fastening tape 30, and the underbody region E4). Is indicated by hatching, and the second area CE2 is indicated by dot hatching.

  In the front region E1, the rear region E2, and the underbody region E4, a plurality of dot-patterned first regions CE1 and second regions CE2 are provided (see FIGS. 4A, 4B, 5, etc.). In the target area E3, a rectangular first area CE1 along the product width direction W and a heart-shaped part formed on the center side of the target area E3 with respect to the first area CE1 in the product longitudinal direction L and the product width direction W. A second region CE2 is provided (see FIG. 4C). In the fastening tape 30, a first region CE1 is provided in a region other than the base region A (intermediate region B, hook sheet region C, tip region D), and a second region CE2 is provided in the base region A. (See FIG. 6).

  The predetermined colors are 196U, 217U, 250U, 496U, 502U, 503U, 510U, 517U, 670U, 671U, 677U, 678U, 684U, 685U, 691U, 692U, 698U in the color sample book of PANTONE (registered trademark), The color corresponds to any one of 699U, 705U, 706U, 2635U, 7422U, 7429U, 7430U, and 7436U. These colors in the PANTONE® color sample book are visible as light pink.

  The determination as to whether or not the color is a predetermined color shown in the PANTONE (registered trademark) color sample book is performed by, for example, comparing the color of the visually observed colored region CE (first region CE1) with the color sample book. Do. Specifically, each of a plurality of people (for example, 10 people) visually observes the color of the colored region CE (first region CE1) and determines which color corresponds to the color sample book. Then, it is determined that the color selected by most people is the color of the area. In the present embodiment, the predetermined color is a color when viewed through the back sheet 24 and the target sheet 36. On the other hand, when the back sheet 24 or the target sheet 36 is colored, it is desirable that the color itself is a predetermined color.

  Further, the colored region CE in each region (in the front region E1, the rear region E2, the target region E3, the fastening tape 30, and the underbody region E4) is the area of the first region CE1 in the region. Is larger than the area of the second region CE2 (see FIGS. 4A to 4C, FIG. 5 and FIG. 6).

  When there are a plurality of first regions CE1 and a plurality of second regions CE2 in a certain region, such as the front region E1, the rear region E2, and the undercarriage region E4, the sum of the areas of the first regions CE1 Is larger than the sum of the areas of the second regions CE2. When there is no second region CE2, the area of the second region CE2 is assumed to be zero.

  As a specific example, the colored region CE in a certain region (for example, the front region E1) may be formed so that the area ratio indicating the area of the first region CE1 with respect to the area of the colored region CE occupies 50% or more. For example, the colored region CE of the front region E1 includes a plurality of first regions CE1 and a plurality of second regions CE2 (see FIG. 4A). In this case, the area ratio is a percentage obtained by dividing the total area of the first region CE1 by the total area of the first region CE1 and the second region CE2. If the area ratio is 50% or more, it can be said that the area of the first region CE1 is larger than the area of the second region CE2 in the front region E1.

  By forming the colored region CE in this way, a person (nurse, mother, etc.) who has seen a certain region (for example, the front region E1) having the colored region CE recognizes the predetermined color (light pink) most strongly. (Recognize that the front area E1 is a light pinkish color). Light pink generally has an image of energy and youth, so it has the effect of making a low-weight infant look healthy. In color psychology, pink is a color that symbolizes pacifism and happiness, and acts to give people a sense of happiness. From a medical point of view, pink is a color that acts on ovarian hormones to secrete hormones and stimulate the brain. Therefore, activation of female hormones also has the effect of promoting maternal formation. In other words, by adopting the pink color as the main color of disposable diapers 1 that low-weight children can only wear, they can lighten and heal the hearts of parents who feel strong anxiety about having low-weight children It can be expected to have a calming effect, relieve stress even temporarily, and give a sense of security. Moreover, since the low weight child is put into NICU and GCU after birth, the effect which promotes the motherhood formation of the mother with respect to the low weight child who cannot share a normal life can be expected.

  As long as the predetermined color (light pink) defined by the PANTONE (registered trademark) color sample book is used, the colored regions of the front region E1, the rear region E2, the target region E3, the fastening tape 30, and the undercarriage region E4 The main colors in CE may be different. For example, 196U can be used as the main color in the front area E1, and 7436U can be used as the main color in the rear area E2. Further, there may be a case where one colored region CE extends over a plurality of regions. For example, as shown in FIG. 4A (or FIG. 5), there is a colored region CE that straddles both the front region E1 and the underbody region E4. Even in this case, it is only necessary that the total area of the first regions CE1 in each region is larger than the total area of the second regions CE2. In addition, for a portion composed of a plurality of regions such as the suspension region E4, the area (total area) of the first region CE1 is larger than the area (total area) of the second region CE2 for each region. Is desirable. For example, in the case of the underbody region E4 shown in FIG. 5, it is desirable that the total area of the first region CE1 is larger than the total area of the second region CE2 only on the right side (left side).

  It is also possible to represent the above-mentioned colors defined in the PANTONE (registered trademark) color sample book in the RGB color system. In this case, a color in which the R value based on the RGB color system is 255 to 232, the G value is 190 to 245, and the B value is in the range of 185 to 245 is colored in the first region CE1 (predetermined) Color). The RGB value can be measured, for example, by using a commercially available colorimeter.

  In addition, it is not preferable to use a red color for the colored region CE because a nurse or the like may mistake the wearer's hematuria or bloody stool. That is, it is desirable that the colored region CE does not include a red color darker than 197U and 707U in the color sample book of PANTONE (registered trademark). The red color that is darker than 197U and 707U in the color sample book of PANTONE (registered trademark) has an R value based on the RGB color system of 239 or more, a G value of 173 or less, and a B value of 175 or less. Corresponds to the color.

  In addition, in the front area E1 and the rear area E2 according to the present embodiment, an information display area IE (area indicated by vertical hatching in FIGS. 4A and 4B) is provided. The information display area IE is an area colored in the same color as the first area CE1. The information display area IE shows information for determining at least one of the front and rear of the disposable diaper 1, the size of the disposable diaper 1, and the type of the disposable diaper 1 (product name, name of company to be sold, etc.). The information display area IE may also be provided in the target area E3, the fastening tape 30, and the underbody area E4. The information display area IE is a portion that a user (nurse or mother) watches when the disposable diaper 1 is worn by a child. Therefore, by coloring this area with light pink, it is possible to give a sense of security when a mother or the like gazes at the area.

<About the white area>
In the skin side direction of the wearer (low weight child) rather than each region (front region E1, rear region E2, target region E3, fastening tape 30, and underbody region E4) where the colored region CE is provided, White areas WE1 to WE5 are provided. A wearer's skin side direction says the direction where a wearer's skin is located, when the disposable diaper 1 is worn.

  The white area WE1 corresponding to the front area E1 is located closer to the wearer's skin side than the front area E1 (area hatched with a diagonal dotted line in FIG. 4A). In the present embodiment, the white region WE1 is formed at the end of the front waistline portion 3 in the product longitudinal direction L with the target region E3 (target tape 29) sandwiched between the white region WE1 and the front region E1. The length of the white area WE1 in the product width direction W is substantially equal to the length of the front area E1 in the product width direction W.

  The white region WE2 corresponding to the rear region E2 is provided at an end of the rear waistline portion 7 in the product longitudinal direction L (a region hatched by a diagonal dotted line in FIG. 4B). In the present embodiment, the white region WE <b> 2 is formed over the entire length of the end portion of the rear waistline portion 7 in the product longitudinal direction L. The length of the white region WE2 in the product width direction W is substantially equal to the length of the rear region E2 in the product width direction W.

  The white region WE3 corresponding to the target region E3 is located closer to the wearer's skin side than the target region E3 (a region hatched with an oblique dotted line in FIG. 4C). In the present embodiment, the white region WE3 is formed at the end of the front waistline portion 3 in the product longitudinal direction L. The length of the white region WE3 in the product width direction W is substantially equal to the length of the target region E3 in the product width direction W. The white region WE3 partially overlaps with the white region WE1.

  The white area WE4 corresponding to the underbody area E4 is located closer to the wearer's skin side than the underbody area E4 (area hatched with a diagonal dotted line in FIG. 5). The white region WE4 is formed outside the underbody region E4 (elastic member 27) in the product width direction W. The length in the product longitudinal direction L of the white region WE4 is substantially equal to the length in the product longitudinal direction L of the undercarriage region E4.

  The white region WE5 corresponding to the fastening tape 30 (region E5) is the skin side of the wearer than the fastening tape 30 when the child wears the disposable diaper 1 by engaging the fastening tape 30 with the target region E3. It is located in the direction (the area hatched by the oblique dotted line in FIG. 6). The white region WE5 in the present embodiment is formed at the end of the front waistline portion 3 in the product longitudinal direction L. The white region WE5 partially overlaps with the white region WE1 and the white region WE3. The length of the white region WE5 in the product width direction W is such that the base region A of the other fastening tape 30 extends from the end on the base region A side of the one fastening tape 30 in a state where the pair of fastening tapes 30 are engaged. It is almost equal to the length to the end of the side.

  The white areas WE1 to WE5 transmit the color of the wearer's skin at a predetermined ratio. As a specific ratio, the light transmittance of the white regions WE1 to WE5 is set to 25% to less than 80%. If the light transmittance is higher than 80%, the skin color is almost transparent, the contrast between the colored region CE and the skin and the white regions WE1 to WE5 is weak, and the effect of providing the white region is reduced. On the contrary, if the light transmittance is less than 25%, the sense of transparency in the white region is weakened, and the gradation effect is reduced. The light transmittance is more preferably 35% to 80%. The light transmittance is measured based on the method A of JISK7105. As the measuring device, for example, an A300 / ZE-2000 type crossing side light type color difference meter (manufactured by Nippon Denshoku Industries Co., Ltd.) is used.

  Further, the white areas WE1 to WE5 are formed so that the light transmittance thereof is higher than the light transmittance of the colored area CE. By increasing the light transmittance in this way, the skin color can be seen through in the white regions WE1 to WE5. Therefore, when the disposable diaper 1 is worn, from the center of the disposable diaper 1 toward the wearer's skin side, the colored region CE (first region CE1), the white region (WE1 to WE5), the order of the skin Become. That is, a gradation of light pink to a color through which the skin is transparent (a color obtained by mixing white and white in the white region) to a skin color is formed. Therefore, the skin color can be shown brightly.

  In the present embodiment, the end portion on the front waistline portion 3 side of the leak-proof sheet 23 in the product longitudinal direction L is disposed so as to cover only a part of the white region WE3 (white regions WE1, WE5) (see FIG. 4C and the like). ). In addition, the end of the leakproof sheet 23 on the rear waistline portion 7 side in the product longitudinal direction L is disposed so as to cover only a part of the white region WE2 (see FIG. 4B).

  Here, in FIG. 4C, the white area WE3A is an area where the leak-proof sheet 23 is applied (area consisting of the leak-proof sheet 23 and the back sheet 24). The white region WE3B is a region where the leak-proof sheet 23 is not applied (a region composed of only the back sheet 24). The light transmittance is higher in the white region WE3B than in the white region WE3A.

  When the disposable diaper 1 having such a configuration is worn, the coloring region CE, the white region WE3A, the white region WE3B, and the skin are arranged in this order from the center of the disposable diaper 1 toward the wearer's skin side. Becomes clearer, and the effect of making the skin color appear brighter is obtained. In this case, for example, the light transmittance is set so that the colored region CE is 15 to 25%, the white region WE3A is 25 to 35%, and the white region WE3B is 39 to 80%.

  Moreover, as for white area | region WE1-WE5, the part with a high light transmittance and the low part may be arrange | positioned by the predetermined pattern. As a result, the light transmittance in each white region is increased or decreased, and the gradation becomes clearer. As the predetermined pattern, for example, a striped pattern composed of unevenness is applied to a white region. This unevenness can be formed by alternately forming ridges having a large amount of fibers and grooves having a small amount of fibers on the outermost nonwoven fabric of two or more nonwoven fabrics constituting the white region.

<Other configurations of disposable diapers>
In the present embodiment, a recess 40 that is recessed in the product longitudinal direction L is formed at an end of the front waistline portion 3 (a part of the white region). The recess 40 is located on the wearer's navel when the disposable diaper 1 is worn. The length α from the bottom surface of the recess 40 in the product longitudinal direction L to the colored region CE is shorter than the length β of the white region WE3 in the product longitudinal direction L (see FIG. 4C). Therefore, in the recessed part 40, since the coloring area | region CE and a wearer's skin approach, the color of the coloring area | region CE can be shown better. Furthermore, compared to the case where the end of the front waistline portion 3 is linear, the range in which the white region WE3 is in contact with the skin increases, so that a gradation effect can be further obtained.

  Further, the position of the center line (the one-dot chain line in FIG. 4C) in the product longitudinal direction L of the target region E3 is 30 mm or more from the end of the front waistline portion 3 (the front end of the back sheet 24) in the product longitudinal direction L. It is desirable that the position be 60 mm or less. If the distance between the target region E3 and the end of the front waistline portion 3 is longer than 60 mm, the area covering the skin increases (the white region WE3 becomes too long) and the skin of the wearer is excessively covered. On the other hand, if the distance between the target region E3 and the front waistline portion 3 is shorter than 30 mm, the area covering the skin is reduced (the white region WE3 is small). Therefore, in any case, the gradation effect is reduced. On the other hand, when the distance between the target region E3 and the front waistline 3 is 30 mm or more and 60 mm or less, the color is light pink (the first region CE1 of the target region E3) to the color through which the skin is transparent (white region WE3). The skin color gradation of the abdomen can make the skin color look better.

  Similarly, when the colored region CE is provided in the fastening tape 30, the position of the center line in the product width direction W (the center position in the tape width direction, see FIG. 3A) in the fastening tape 30 is the product longitudinal direction. It is desirable that it is 30 mm or more and 60 mm or less from the end of the rear waistline portion 7 at L (the rear end of the back sheet 24). In this case, when the disposable diaper 1 is worn (that is, the state in which the fastening tape 30 is engaged with the target area E3; see FIG. 6 and the like), the light pink (first area CE1 of the fastening tape 30) to the transparent color ( The skin color can be shown better by the gradation of the skin color of the white region WE5) to the abdomen.

<About wearing disposable diapers>
Here, when the disposable diaper 1 is actually worn, the fastening tape 30 is engaged with the target tape 29 (target region E3). At this time, there are cases where the pair of fastening tapes 30 are overlapped and stopped (when the fastening tapes 30 are engaged with each other). In this case, first, the lower fastening tape 30 is engaged with the center portion of the target tape 29 in the front waistline portion 3, and the other fastening tape 30 is engaged on the fastening tape 30. For this reason, a pair of fastening tape 30 will be naturally located in the center part of a wearer's front waistline part 3. FIG. As a result, the part where the fastening tape 30 extends from the main body of the disposable diaper 1 is located away from the groin of the wearer. Thereby, even if the foot moves in a positioning posture in which the foot is bent into an M shape, the fastening tape 30 is less likely to receive a force of turning up from the groin.

  7A to 7C are enlarged views of the vicinity of the target region E3. FIG. 7A is a diagram showing the target region E3. FIG. 7B is a view when the fastening tape 30 on the lower side is engaged with the target tape 29. FIG. 7C is a view when the other fastening tape 30 is engaged with the fastening tape 30 of FIG. 7B. In this example, it is assumed that the fastening tape 30 is not provided with the colored region CE.

  The colored region CE in the target region E3 is a first region CE1 along the product width direction W and a second region formed on the center side of the target region E3 with respect to the first region CE1 in the product longitudinal direction L and the product width direction W. Region CE2 (see FIG. 7A). The second region CE2 is provided at a position where at least a part of the second region CE2 is covered by the fastening tape when the fastening tape 30 is engaged with the target region E3 (part of the second region CE2 is covered in FIG. 6). 7B and 7C are all covered).

  Here, as shown in FIG. 7C, when the pair of fastening tapes 30 is overlapped with the center of the fastening tape 30 in the tape width direction being aligned, the upper fastening tape 30 is moved to the end of the lower fastening tape 30. The part is straddled in the tape width direction, and is engaged with the target tape 29 on both sides of the straddle. In the figure, the area where the upper fastening tape 30 (hook sheet 34) is engaged with the target tape 29 is hatched rightward.

  The engagement force P1 with the target tape 29 is larger than the engagement force P2 with the other fastening tape 30 (P1> P2, which will be described later). Under such circumstances, the upper fastening tape 30 of the present embodiment engages with the target tape 29 in the hatched area on the right in FIG. 7C, and therefore, only when the lower fastening tape 30 is engaged. In comparison, the engaging force is increased. In addition, since the base side (side flap 14 side) of the fastening tape 30 is located closer to the inguinal part than the end part, the base side of the fastening tape 30 receives a greater force of turning up than the end part. become. However, in the present embodiment, the upper fastening tape 30 is engaged with the target tape 29 across the lower fastening tape 30 on the base side of the fastening tape 30 (the portion that receives a large turning force) ( Since the engaging force on the base side of the fastening tape 30 is high, the fastening tape 30 is unlikely to come off.

  On the other hand, the upper fastening tape 30 straddles the end of the lower fastening tape 30 in the tape width direction. Conversely, the end of the upper fastening tape 30 is positioned only on the lower fastening tape 30. It becomes the structure to do. The end of the upper fastening tape 30 has a lower engagement force than the base side engaged with the target tape 29. For this reason, it is easy to remove the fastening tape 30 by pinching the end of the fastening tape 30.

  Thus, since the fastening tape 30 can be easily removed and the fastening tape 30 can be removed without applying stress to the child, the disposable diaper 1 according to the present embodiment has a minimum handling (not touching the child as much as possible). Suitable for low-weight infants who are required. On the other hand, since the fastening tape 30 is unlikely to come off even when the leg bent in an M shape moves, the disposable diaper 1 of the present embodiment is suitable for a low-weight child requiring a positioning posture.

  In the present embodiment, as shown in FIG. 7C, the end portion of the upper fastening tape 30 is aligned with the position of the end portion on the side flap 14 side of the hook sheet region C of the lower fastening tape 30, and The pair of fastening tapes 30 are stacked with the center of the fastening tape 30 in the tape width direction being aligned. Then, when the pair of fastening tapes 30 are overlapped in this way, in this embodiment, the upper fastening tape 30 is attached to the target tape 29 on both sides of the end of the lower fastening tape 30 across the tape width direction. Is engaged. In addition, in this embodiment, the state which match | combined the waist dimension on the design of the disposable diaper 1 with the edge part of one fastening tape 30 in the edge part by the side flap 14 side of the hook sheet area | region C of the other fastening tape 30. Therefore, the upper fastening tape 30 can be engaged with the target tape 29 on both sides of the end of the lower fastening tape 30 in the tape width direction. However, the position of the upper fastening tape 30 with respect to the lower fastening tape 30 is not limited to the position shown in FIG. 7C. Even if the upper fastening tape 30 is shifted to the left or right from the position shown in FIG. 7C, it is engaged with the target tape 29 on both sides of the end of the lower fastening tape 30 in the tape width direction. If so, the engagement force on the base side of the fastening tape 30 is increased, and the fastening tape 30 is unlikely to come off.

  In the present embodiment, the width of the end of the hook sheet region C on the side flap 14 side (the dimension in the tape width direction) is larger than the width of the end of the fastening tape 30. By forming the fastening tape 30 in such a shape, when the pair of fastening tapes 30 are stacked with the center of the fastening tape 30 in the tape width direction being aligned, the upper fastening tape 30 becomes the lower fastening tape. It becomes possible to engage with the target tape 29 on both sides of the end of 30 across the tape width direction.

  And in this embodiment, the length of the tape width direction of the fastening tape 30 is formed shorter than the length of the product longitudinal direction L of the colored region CE in the target region E3. Therefore, even when the second region CE2 is covered with the fastening tape 30, a part of the colored region CE (first region CE1) colored with a predetermined color appears above and below the fastening tape 30 (FIG. 7C). That is, even when the second region CE2 is entirely covered with the fastening tape 30, the first region CE1 colored in a predetermined color appears on the wearer's skin side in a band shape. Accordingly, even when the disposable diaper 1 is worn, a light pink color (the first region CE1 of the target region E3), a transparent color (white region WE3), and a gradation of the skin color can be obtained, so that the skin can appear brighter. .

<Engagement force of fastening tape 30>
In order to engage the fastening tape 30 (specifically, the hook sheet 34 of the fastening tape 30), the engaging force of the fastening tape 30 needs to be 0.1 N / 10 mm or more. If the engaging force of the fastening tape 30 is smaller than 0.1 N / 10 mm, even if the fastening tape 30 can be engaged, the fastening tape 30 is disengaged when receiving the force, and the fastening tape 30 is engaged. The match is insufficient.

  The fastening tape 30 is engaged with the target tape 29 (target region E3) of the front waistline portion 3. Therefore, when the engagement force between the fastening tape 30 (hook sheet 34) and the target tape 29 of the front waistline portion 3 is P1 (unit: N / 10 mm), P1 is required to be 0.1 N / 10 mm or more. Is done.

  Furthermore, the fastening tape 30 of this embodiment is also engaged with the target sheet 36 of the other fastening tape 30. Therefore, when the engagement force between the fastening tape 30 (hook sheet 34) and the target sheet 36 of the other fastening tape 30 is P2 (unit: N / 10 mm), P2 may be 0.1 N / 10 mm or more. Required.

  On the other hand, in order to make it easy to remove the fastening tape 30, the engaging force of the fastening tape 30 is preferably 0.5 N / 10 mm or less. If the engaging force of the fastening tape 30 exceeds 0.5 N / 10 mm, it becomes difficult to remove the fastening tape 30, and the force to remove the fastening tape 30 places a burden on the child, which is contrary to the minimum handling for low-weight children. For this reason, it is desirable that the engaging force of the fastening tape 30 be in the range of 0.1 to 0.5 N / 10 mm.

  Further, in this embodiment, when the engagement force between the fastening tape 30 and the target tape 29 of the front waistline portion 3 is P1, and the engagement force between the fastening tape 30 and the target sheet 36 of the other fastening tape 30 is P2, P1> P2. The reason for this relationship is that it is necessary to suppress the rigidity of the fastening tape 30 so that the stress applied to the wearer can be suppressed even if the fastening tape touches the wearer, and the material and thickness of the target sheet 36 of the fastening tape. This is because there are restrictions. Here, P1 is 0.5 to 0.7 N / 30 mm (a numerical value of 1/3 when the unit is N / 10 mm), and P2 is 0.8 to 1.1 N / 30 mm.

  The engaging force of the fastening tape 30 is measured using an autograph tester (AG-X10plus) manufactured by Shimadzu Corporation. Specifically, a sample is prepared by cutting the hook sheet region C into a rectangular shape with the widest possible width from the fastening tape 30 to be measured. Similarly, a sample in which a target (target tape 29 or target sheet 36) with which the fastening tape 30 is engaged is cut out in a size larger than that of the hook sheet 34 is prepared. Next, a 700 g roller (diameter: 85 mm, width: 45 mm) is moved at a speed of 5 mm / min along the attaching / detaching direction of the main fastening tape 30 to press both samples. Both the crimped samples are set in the above-mentioned ophograph testing machine, the engaging force of both samples at a pulling speed of 300 mm / min is measured, and the value converted into the engaging force per unit width of 10 mm based on the width dimension of the sample. The engagement force (unit: N / 10 mm) is used. At this time, the pulling direction is set so that the hook sheet surface has an angle of 135 degrees with respect to the target surface (the jig surface on which the target sample is placed). The peel direction of the hook sheet is the main attaching / detaching direction when the fastening tape 30 is operated (detached).

=== Examples and Comparative Examples ===
The following experiment was conducted in order to compare the comfort of the child's skin due to the difference in color (the skin looks bright) and the visibility from outside the incubator.

  For a disposable diaper in which a colored region CE (the area of the first region CE1 is larger than the area of the second region CE2) is provided only in the rear region E2, 670U in a color sample book of PANTONE (registered trademark) as a predetermined color. (Example 1), 698U (Example 2), 496U (Example 3), 707U (Comparative Example 1), 197U (Comparative Example 2), 710U (Comparative Example 3), 178U (Comparative Example 4), 292U ( Each of those given the color of Comparative Example 5) was prepared. The colors of Examples 1 to 3 correspond to light pink, the colors of Comparative Examples 1 and 2 correspond to dark pink, the colors of Comparative Examples 3 and 4 correspond to red, and the color of Comparative Example 5 corresponds to blue.

  The evaluation method was performed by a nurse (or mother) visually recognizing the child wearing the disposable diapers colored in the above colors from outside the incubator and comprehensively judging the personal impression. Specifically, 10 nurses (or mothers) visually observed each disposable diaper, and more than 6 nurses judged that the skin of the child was good and that visibility was high from outside the incubator. ○, other than that was marked with ×.

  Similarly, the following table summarizes the results of evaluating the target region E3, the fastening tape 30, and the underbody region E4 by performing the same coloring as described above. In the table, (1) is an example in which only the rear region E2 is colored, (2) is an example in which only the target region E3 is colored, and (3) is an example in which only the fastening tape 30 is colored. Yes, (4) is an example in which only the underbody region E4 is colored.

  As is clear from the above table, the disposable diapers (Examples 1 to 3) using light pink have a better skin appearance than the disposable diapers with other colors (Comparative Examples 1 to 5), and outside the incubator The result that the visibility from was also high was obtained. When dark peach color was used as in Comparative Examples 1 and 2, the colored portion became dark inside the incubator, and it was difficult to see from outside the incubator. Moreover, when using red type | system | group and blue type | system | group like Comparative Examples 3-5, the result that a skin image and the visibility from the outside of an incubator were low, and a red type | system | group was easy to be mistaken for blood was obtained.

  The above embodiment is presented as an example and does not limit the scope of the invention. For example, in the said embodiment, although the disposable diaper 1 described the example used in an incubator, it is not restricted to this. Even outside the incubator, the illuminance may be dark depending on the situation of the room (natural environment and lighting brightness).
