Description

  The present invention relates to a pants-type disposable diaper.

  In recent years, exterior materials used on the outermost side of pants-type disposable diapers have been improved to be thinner and softer in order to achieve a feeling of wearing close to ordinary underwear. However, as the exterior material becomes softer, the exterior material may not be able to withstand the tension applied to the exterior material when the diaper is mounted, and the exterior material may be damaged. In this specification, when “wearing” or “when wearing” is used, both when the wearer wears a pants-type disposable diaper and when the caregiver wears the pants-type disposable diaper. Shall be included.

  In addition, because the strength of the pants-type disposable diaper may differ depending on the part due to the difference in the number of laminated sheet materials or the like, it is preferable that the part with higher strength is gripped when worn. . However, the appearance color of diapers often has the same color (for example, white) as a whole, and for the wearer or caregiver (hereinafter referred to as “wearer etc.”), which part has the strength. In many cases, it is difficult to understand whether it is expensive and convenient to hold.

  Patent Document 1 discloses a configuration in which a pressing sheet (27) for pressing front and rear ends of an interior material from the skin surface side is provided in a pants-type disposable diaper (paragraph [0017], FIG. 3 and the like). reference). In this configuration, it is considered that the strength of the portion to which the pressing sheet of the exterior material is applied is stronger than the other portions. However, since a sheet having the same color as that of the base material sheet of the exterior material is used as the presser sheet in a normal case, it is difficult to distinguish the portion provided with the presser sheet from the appearance of the exterior material.

  Moreover, in patent document 2, the structure which strengthened the intensity | strength of a part of exterior material by the inner-layer sheet | seat and outer-layer sheet | seat which comprise the exterior material of an underpants type disposable diaper being partially melted and solidified and integrated. It is disclosed (see summary etc.). However, even in this configuration, there is a problem that it is difficult for a wearer or the like to distinguish a portion (melt-bonded portion) in which the inner layer sheet and the outer layer sheet of the exterior material are melted and solidified.

  The front pressing sheet 25 and the rear pressing sheet 26 are formed of a nonwoven fabric or the like. The front pressing sheet 25 is a base sheet positioned on the front abdominal part 21 such that the rear side part in the center part in the horizontal direction X covers the front side end part in the vertical direction Y of the interior material 3 from the skin surface side. It joins to the part of 24 from the skin surface side. The rear pressing sheet 26 is a base material positioned on the rear portion 22 so that the front portion in the center portion in the lateral direction X covers the rear end portion in the longitudinal direction Y of the interior material 3 from the skin surface side. The sheet 24 is joined from the skin surface side. An adhesive (for example, hot melt adhesive) or welding (for example, heat welding or ultrasonic welding) or the like is used for joining the front pressing sheet 25 and the rear pressing sheet 26 and the base sheet 24.

  The width in the lateral direction X of the front pressing sheet 25 and the rear pressing sheet 26 is the same as the width in the lateral direction X of the front abdomen 21 and the rear portion 22 of the exterior material 2, and the front pressing sheet 25 and the rear pressing sheet 26 are The entire region in the lateral direction X of the front abdomen 21 and the back part 22 is covered. Further, the width in the vertical direction Y of the front pressing sheet 25 and the rear pressing sheet 26 is smaller than the width in the vertical direction Y of the front part 21 and the back part 22 of the exterior material 2. For this reason, the front pressing sheet 25 is disposed so as to cover the area closer to the front side in the longitudinal direction Y of the front abdomen 21. Further, the rear pressing sheet 26 is disposed so as to cover a region closer to the rear side in the longitudinal direction Y of the back portion 22.

  The front pressing sheet 25 and the rear pressing sheet 26 are different in color (for example, red) from colors (for example, white) of the skin surface side base sheet 241 and the outer surface side base sheet 242 constituting the base sheet 24. have. Since thin sheets, such as a nonwoven fabric, are used for the skin surface side base sheet 241 and the outer surface side base sheet 242, the colors of the front pressing sheet 25 and the rear pressing sheet 26 are transparent from the outer surface side through the base sheet 24. Looks. Thereby, the color of the external appearance of the part in which the front side pressing sheet 25 and the rear side pressing sheet 26 in the front abdomen 21 and the back part 22 of the exterior material 2 are provided is visually recognized in a color different from the other parts. Further, the strength of the portion of the exterior material 2 provided with the front pressure sheet 25 and the rear pressure sheet 26 is higher than that of the other portions of the exterior material 2 by the amount of the sheet materials 25 and 26 applied thereto. Thereby, in this embodiment, the reinforcement parts 5 and 6 are comprised by the part in which the front side pressing sheet 25 and the rear side pressing sheet 26 of the exterior material 2 were provided.
