Description

  The present invention relates to a disposable diaper including a fastening tape on one of a front waistline portion and a rear waistline portion.

  2. Description of the Related Art Conventionally, as disposable diapers mainly used for infants and the like, so-called open-type disposable diapers in which fastening tapes for fastening are provided on side flaps at the rear waistline portion are widely provided. An open-type disposable diaper having a fastening tape as described above is widely used particularly for newborns and infants because of its ease of attachment and detachment.

  In such an open-type disposable diaper, a structure in which the base end portion on the skin contact surface side of the fastening tape is covered with a side flap (nonwoven fabric) that is more flexible than the fastening tape is known (for example, Patent Document 1). ). According to such a disposable diaper, since the fastening tape is prevented from stimulating the skin of an infant or the like, the infant is less likely to feel discomfort or pain.

Japanese Patent Laying-Open No. 2003-70840 (FIG. 1)

  According to the above-described conventional disposable diaper, since the base end portion on the skin contact surface side of the fastening tape is covered with a flexible nonwoven fabric, the fastening tape is suppressed from stimulating the skin of an infant or the like, but the disposable diaper There was still room for improvement in the irritation and discomfort caused by touching the fastening tape when attaching and detaching.

  Specifically, the fastening tape is always touched when the disposable diaper is attached and detached, and when the fastening tape is spread, when it is fastened to the target tape, when it is peeled off from the target tape, and after use, the disposable diaper is rolled up. It can be touched many times (a total of 8 or more times with a pair of left and right fastening tapes).

  However, since the fastening tape has the only protrusion in the disposable diaper and is the most rigid member, it is easy to feel irritation and discomfort by touching the fastening tape. In particular, it is known that mothers whose maternal hormone secretion is increased after childbirth are likely to feel a strong sense of discomfort or disgust with hard or pointed items.

  In recent disposable diapers, the hardness of the fastening tape has become more conspicuous due to the adoption of a thin absorbent body and the improvement of the texture of the top sheet.

  Then, this invention is made | formed in view of such a condition, and it aims at provision of the disposable diaper which can reduce the irritation | stimulation and discomfort at the time of touching a fastening tape.

  Accordingly, specific dimensions and the like should be determined in consideration of the following description. Moreover, the part from which the relationship and ratio of a mutual dimension differ also in between drawings may be contained.

(1) Schematic shape of disposable diaper FIG. 1 is a plan view of a disposable diaper 10 according to the present embodiment. As shown in FIG. 1, the disposable diaper 10 is an open type having a front waistline portion 20, a crotch portion 30, and a rear waistline portion 40. The disposable diaper 10 can be suitably used particularly for infants.

The front waistline portion 20, the crotch portion 30, and the rear waistline portion 40 constitute an absorbent main body 15. The absorbent main body 15 has a vertically long shape including the liquid retaining absorbent body 35. In the present embodiment, the absorber 35 is provided across the front waistline portion 20, the crotch portion 30, and the rear waistline portion 40. Absorber 35 has a shape such that the width at the central portion is narrowed in the product longitudinal direction D _L of the absorbent body 15. The shape of the absorber 35 is not limited to the shape shown in FIG. 1 and may be a simple rectangle. Further, the absorber 35 may be provided at least in the crotch part 30.

The absorbent main body 15 is the same as a conventional open-type disposable diaper, and can be appropriately configured using a known member or material. Moreover, the absorbent body 15, a liquid permeable topsheet which is not shown, the rear along standing gathers are provided on the side edges of the absorbent body 15 along the product longitudinal direction D _L, and the product width direction D _W girth A waist gather provided in the portion 40 may be provided.

Side flaps 50 are provided on the side edges of the absorbent main body 15 in the product width direction _DW . The side flap 50 is configured by one or two or more non-woven fabrics that are stacked.

In this embodiment, side flaps 50 are provided over the entire product longitudinal direction D _L of the absorbent body 15. That is, the side flap 50 is provided from the front waistline portion 20 to the rear waistline portion 40. The width of the side flap 50 corresponding to the crotch portion 30 is narrower than the width of the side flap 50 corresponding to the front waistline portion 20 and the rear waistline portion 40. Incidentally, the side flaps 50 may not be necessarily provided over the entire product longitudinal direction D _L of the absorbent body 15, for example, may be provided only in a region corresponding to the back waistline portion 40.

Further, a leg elastic member 55 that can be expanded and contracted along the product longitudinal direction D _L of the absorbent main body 15 is provided at the side edge portion in the product width direction D _W of the absorbent main body 15, specifically, the side flap 50. . The leg elastic members 55, the absorbent body 15 is shrunk in the product longitudinal direction D _L. Thus contracted absorbent body 15 may be extended to product longitudinal direction D _L.

A fastening tape 100 is attached to the side flap 50. Specifically, the fastening tape 100 extends from the rear waistline portion 40 to the outside of the absorbent main body 15 in the product width direction _DW . The fastening tape 100 is configured to be fixed to the front waistline portion 20. A hook sheet 110 (not shown in FIG. 1, see FIG. 2) of the fastening tape 100 is engaged with a target tape 60 provided on the back sheet 70 (not shown in FIG. 1, see FIG. 3) side of the front waistline portion 20. To do.

The fastening tape 100 may be attached to the side flap 50 so as to extend from the front waistline portion 20 to the outside of the product width direction _DW of the absorbent main body 15 instead of the rear waistline portion 40, but lay on its back. In the case of infants who often change disposable diapers in a state of being worn, it is preferable that the fastening tape 100 is attached to the rear waistline portion 40.

(2) Shape of Fastening Tape Next, the shape of the fastening tape 100 will be described with reference to FIGS. FIG. 2 is an enlarged view of the fastening tape 100 portion (side flap 50 side) of the disposable diaper 10. FIG. 3 is a sectional view of the fastening tape 100 taken along line F3-F3 in FIG. FIG. 4 is a schematic diagram of a cross-sectional shape of the fastening tape 100 shown in FIG.

  As shown in FIGS. 2 to 4, the fastening tape 100 is attached to a region of the side flap 50 corresponding to the rear waistline portion 40 (see FIG. 1). The fastening tape 100 includes a hook sheet 110 provided with a plurality of engagement hooks 111 and a base sheet 105 formed of a nonwoven fabric. The hook sheet 110 is fixed to the base sheet 105.

  The hook sheet 110 is fixed to the base sheet 105, specifically, bonded. The hook sheet 110 and the base sheet 105 are preferably joined so that the rigidity of the fastening tape 100 does not become higher than necessary. Specifically, it is preferable that the hook sheet 110 and the base sheet 105 are joined by a hot melt adhesive applied intermittently such as a dot shape, a line shape, or a spiral shape. The hook sheet 110 and the base sheet 105 may be joined by heat sealing or the like.

  In order to reduce the rigidity of the hook sheet 110, various known methods such as reducing the thickness of the base material portion of the hook sheet 110 or increasing the gap of the base material portion can be used.

The base sheet 105 is composed of one or two or more non-woven fabrics stacked. As the base sheet 105, a non-woven fabric manufactured by a manufacturing method such as spunbond (SB) or spunbond-meltblown-spunbond (SMS) can be used. The basis weight of the nonwoven fabric constituting the base sheet 105 (total basis weight in the case of a plurality of sheets) is 30 to 120 g / m ² , preferably 40 to 90 g / m ² . When the weight per unit area is less than 30 g / m ^2, it is difficult to maintain the strength for holding the disposable diaper 10, and when the fastening tape 100 is used, the frequency of breaking in the region where the hook sheet 110 does not exist increases. On the other hand, when the weight per unit area exceeds 120 g / m ² , the bending rigidity of the fastening tape 100 becomes too high.

In the present embodiment, a material of 80 g / m ² of SB nonwoven fabric is used for the base sheet 105. The hook sheet 110 was made of SB non-woven fabric 100 g / m ² .

The fastening tape 100 also includes a raised portion 130 adjacent to the hook sheet 110 on the outer side in the product width direction _DW of the hook sheet 110. Further, in the present embodiment, the fastening tape 100 includes a raised portion 120 adjacent to the hook sheet 110 inside the product width direction _DW of the hook sheet 110. That is, in the present embodiment, the raised portions 120 and 130 are provided on the outer side of the product width direction _{DW and the} inner side of the product width direction _DW of the hook sheet 110, respectively.

  The hook sheet 110, the raised portion 120, and the raised portion 130 are provided on the flat surface of the base sheet 105 on the skin contact side. The raised portion 120 and the raised portion 130 have a thickness that is flush with the hook sheet 110.

  Specifically, the raised portion 120 and the raised portion 130 have substantially the same thickness as the hook sheet 110. More specifically, the level difference between the fastening tape 100 in the region where the raised portion 120 and the raised portion 130 are present and the fastening tape 100 in the region where the hook sheet 110 is present is −0.28 to 0.46 mm or less.

  As a result, the step at the front end (free end) of the fastening tape 100 is eliminated, and it is difficult to feel a sense of incongruity of the hook sheet 110 when the fastening tape 100 is touched.

  The step is a distance (d in the drawing) between the position of the surface of the hook sheet 110 where the engagement hook 111 is formed and the position of the surface of the raised portion 130. On the basis of the surface of the hook sheet 110, plus (not shown) means that the raised portion (the raised portions 120, 130) is thick, and minus means that the raised portion is thin.

  The difference in thickness means that the thickness of the fastening tape 100 including the base sheet 105 in the region where the hook sheet 110 exists and the fastening tape including the base sheet 105 in the region where the raised portion 130 (the raised portion 120) exists. It is the difference from 100 thickness. That is, as in the present embodiment, when the raised portion does not have a hook seat cover as described later, the step is equal to the difference in thickness.

The difference in level difference and thickness was measured using a PEACOCK dial thickness gauge manufactured by Ozaki Mfg. Co., Ltd. In the measurement, a circular measuring terminal having a diameter of 10 mm was used so that a load of 4.5 gf / cm ² was applied to the fastening tape 100 (the raised portion 130). In this state, the center of the measuring terminal to the center in the product longitudinal direction D _L of the site to be measured so as to be positioned, to measure the difference between the level difference and thickness.

In the present embodiment, the width in the product longitudinal direction D _L of the base sheet 105 and the raised part 130 is substantially the same as the width of the hook sheet 110. Incidentally, if the width of definitive product longitudinal direction D _L of the hook sheet 110 is narrower than the width in the product longitudinal direction D _L of the base sheet 105, the width of the raised part 130 may be wider than the width of the hook sheet 110 Absent. In this case, the width of the raised part 130 is preferably not wide or less in the product longitudinal direction D _L of the base sheet 105.

In the present embodiment, the KES bending stiffness value in the product width direction _DW of the fastening tape 100 in the region where the hook sheet 110 is provided is preferably 1.64 gf · cm ² / cm or less. Exceeding such a KES bending stiffness value is not preferable because it increases irritation and discomfort when touching the fastening tape 100.

The KES bending stiffness value was measured using a KES bending measuring machine manufactured by Kato Tech Co., Ltd. Specifically, B value (bending rigidity) was measured. In the case of using a KES bending measuring machine, respectively was measured along the product width direction D _W and the product longitudinal direction D _L, it is preferable that the value or less in both directions.

  A means for reducing the bending rigidity of the hook sheet 110 can be realized by reducing the thickness of the base sheet 105 to which the hook sheet 110 is bonded or by reducing the thickness of the hook sheet 110.

(3) Modification Example Next, a modification example of the fastening tape will be described with reference to FIGS. In the following, the parts different from the above-described fastening tape 100 will be mainly described.

(3.1) Modification Example 1
FIGS. 5A and 5B are an enlarged view of the fastening tape 100A according to this modification and a schematic view of the cross-sectional shape of the fastening tape 100A, respectively.

  As shown in FIGS. 5A and 5B, the fastening tape 100A includes a raised portion 120A and a raised portion 130A. The raised portion 120A and the raised portion 130A have a hook seat cover portion 141 and a hook seat cover portion 142, respectively.

The hook sheet cover portion 141 extends from the raised portion 120A to the hook sheet 110 side, and covers one end portion of the hook sheet 110 in the product width direction _DW . Similarly, the hook sheet cover portion 142 extends from the raised portion 130A to the hook sheet 110 side, and covers the other end portion of the hook sheet 110 in the product width direction _DW .

The thicknesses of the hook seat cover portion 141 and the hook seat cover portion 142 are preferably thinner than the thicknesses of the raised portion 120A and the raised portion 130A. The hook seat cover portion 141 and the hook seat cover portion 142 can be configured using, for example, SB nonwoven fabric 27 g / m ² . The hook seat cover portion 141 and the hook seat cover portion 142 are in a state of biting into the engagement hook 111, and the thickness in the region where the hook seat cover portion 141 and the hook seat cover portion 142 exist, the raised portion 120A, and the raised portion The thickness in the region where 130A exists is substantially the same.

In the case of the fastening tape 100A, the level difference between the fastening tape 100A in the region where the base sheet 105 and the raised portion 120A or the raised portion 130A exist and the fastening tape 100A in the region where only the hook sheet 110 exists is shown in FIG. It may be larger than the step in the portion of the fastening tape 100 shown in FIG. This is because the raised portion made of a soft nonwoven fabric compared to the hook sheet 110 covers the end of the hook sheet 110 in the product width direction _DW , and it is difficult to feel uncomfortable.

  In the case of this modified example, the step is the distance (d ′ in the drawing) between the position of the surface of the hook sheet 110 and the surface position of the hook sheet cover part 142 (hook sheet cover part 141). Further, the difference between the thickness of the base sheet 105 and the raised portion 130 and the thickness of the hook sheet 110 is preferably 1.08 mm or less as shown in the examples described later. If the thickness difference exceeds 1.08 mm, it is not preferable because the possibility of hindering the engagement of the disposable diaper of the fastening tape 100A increases.

(3.2) Modification 2
FIGS. 6A and 6B are an enlarged view of the fastening tape 100B according to this modification and a schematic view of the cross-sectional shape of the fastening tape 100B, respectively.

  As shown in FIGS. 6A and 6B, the fastening tape 100B has a hook seat cover portion 141A and a hook seat cover portion 142A, respectively, similarly to the fastening tape 100A, the raised portion 120B and the raised portion 130B. In the fastening tape 100B, the engagement hook 111 is not provided in the area of the hook sheet 110B covered with the hook sheet cover part 141A and the hook sheet cover part 142A.

  With such a configuration, the level difference between the fastening tape 100 in the region where the base sheet 105 and the raised portion 120B or the raised portion 130B exist and the fastening tape 100 in the region where the hook sheet 110B exists is compared with the fastening tape 100A. Can be made smaller.

(3.3) Other Modification Examples FIGS. 7A to 7D show other modification examples of the fastening tape. The fastening tape 100C shown in FIG. 7A includes a raised portion 120C and a raised portion 130C, and a hook seat cover 141C and a hook seat cover 142C that are separate from the raised portion 120C. As the raised portion 120C and the raised portion 130C, 35 g / m ² of air-through nonwoven fabric (AT) that can also be expected to have an effect as a cushioning material was used. Further, as the hook sheet cover 141C and the hook sheet cover 142C, SMS nonwoven fabric 15 g / m ² was used in order to suppress the thickness.

  In the fastening tape 100D shown in FIG. 7B, the base sheet 105A and the raised portion 130D are integrally formed.

  The fastening tape 100E shown in FIG. 7C has a configuration similar to that of the fastening tape 100D, but the raised portion 130E is wound around to the flat surface of the base sheet 105 on the non-skin contact side.

The fastening tape 100F shown in FIG. 7D has a similar configuration to the fastening tape 100D, but the base material sheet 105F and the raised portion 130F are made of the same material (for example, ^two SB nonwoven fabrics 30 g / m ² are stacked). The base material sheet 105F and the raised portion 130F are joined together.

(4) Action / Effect Table 1 shows the comparative evaluation results of the fastening tape. As shown in Table 1, tests were conducted on the fastening tapes according to Examples 1 to 5 and Comparative Examples 1 to 3.

  As shown in Table 1, comparative evaluation was performed about the fastening tape which concerns on Examples 1-6 and Comparative Examples 1-4. In the comparative evaluation test, a disposable diaper “Mooney Nene Tailoring S size” manufactured by Unicharm Co., Ltd. was used, and the fastening tape according to Examples 1 to 6 and the fastening tape according to Comparative Examples 1 to 4 were sequentially disposed. A sample for an evaluation test was prepared by changing to.

  In the evaluation test, since the fastening tape is intended for people who “feel the object (foreign matter) with different hardness from the diaper body”, the test subject is screened in advance, and the disposable diaper that is usually used is fastened. The subjects were those who had the above impression on the tape. Specifically, 30 mothers who answered yes to the question “Do you feel that the fastening tape is different from the diaper body (foreign matter)?” For mothers raising 2-6 months infants The mother was selected and asked, “Did you feel a foreign object or discomfort in the fastening tape?”

  In response to the question, a sample in which the ratio of the number of persons in the following (1) or (2) exceeds 60% has a good sensory evaluation (tactile feeling) and was evaluated as OK.

(1) Feel no foreign object / discomfort at all (2) Feel almost no foreign object / discomfort (3) Not say either (4) Feel a little foreign object / discomfort (5) Feel a sense of foreign object / discomfort According to the result of such an evaluation test, the step is preferably in the range of −0.28 to 0.46 mm. The thickness difference is preferably in the range of −0.28 mm to 1.08 mm. The thickness difference was measured at the tip (“A” portion shown in the schematic diagram of Table 1) and the fastening portion (“B” portion shown in the schematic diagram of Table 1).

  That is, according to the fastening tape 100, 100A to 100F provided in the disposable diaper 10 described above, a raised portion adjacent to the hook sheet is provided, and the raised portion has a thickness that is flush with the hook sheet. That is, since the surface of the raised portion and the surface of the hook sheet are substantially flush with each other, it is difficult to feel irritation or discomfort due to the engagement hook 111 provided on the hook sheet even if the fastening tape is touched. That is, the thickness at which the raised portion is flush with the hook sheet is not necessarily limited to the above-described stepped range, and many users do not feel a foreign object or discomfort in the fastening tape portion. Any level difference is acceptable.

  When touching the surface of the fastening tape on the hook sheet side so that the finger slides from the main body side of the disposable diaper toward the tip, it is effective to set the above-mentioned “step” within a predetermined range. Further, when touching the fastening tape and the hook sheet so as to sandwich the fastening tape in the thickness direction, it is effective to set the above-described “thickness difference” within a predetermined range. In particular, when touching the surface of the hook sheet side from the body side of the disposable diaper toward the tip, the fastening tape is engaged with the disposable diaper while preventing the body of the infant from being excessively pressed. This is particularly true when the mother wishing to engage the fastening tape with the target tape 60 after aligning the fastening tape with the desired position of the target tape 60 of the disposable diaper.

Further, in the present embodiment, the raised portion is provided on both the outer side and the inner side of the product width direction D _W of the hook sheet, so when picking the fastening tape, the hook sheet and the inner side of the product width direction D _W than the hook sheet Even when touching this part, it is difficult to feel irritation or discomfort due to the engagement hook 111.

Furthermore, when a hook sheet cover portion that covers the end portion of the hook sheet in the product width direction _DW is provided, even when the end portion of the hook sheet is touched, a difference in level between the hook sheet and the raised portion is felt. It is difficult to feel the irritation and discomfort caused by the engagement hook 111. Further, since the end portion of the hook sheet in the product width direction _DW is covered with the hook sheet cover portion, the end portion can be prevented from being turned over. Thereby, the irritation | stimulation and discomfort at the time of touching a fastening tape can further be reduced.
