Definitions

  • the present invention relates to a pants-type disposable diaper.
  • both sides of the abdominal exterior body and both sides of the back exterior body are joined to form a cylindrical shape, and the center in the width direction of the inner surface of the abdominal exterior body To the central portion in the width direction of the inner surface of the back side exterior body, and an interior body that absorbs excrement, and the abdominal side exterior body and the back side exterior body are separated from each other without being continuous on the crotch side (For example, see Patent Documents 1 to 4).
  • Such an exterior two-part type has the advantage that it is not necessary to punch out a leg opening for passing a leg, or even if it is punched out, a small area is required. That is, since the separation piece (hereinafter also referred to as trim) is disposed of, the waste of the material (hereinafter also referred to as trim loss) can be suppressed.
  • the exterior body is configured to be able to extend to the crotch side, and the widthwise central part of the exterior body is extended to the crotch side with respect to both sides at the time of manufacture. It has been proposed that the edge of the leg opening located on the side of the interior body is obliquely upward toward the side edge, and the edge of the leg opening is shaped around the wearer's buttocks and the buttocks (See Patent Documents 3 and 4).
  • the main problem of the present invention is to provide a pants-type disposable diaper of an exterior two-split type that can be manufactured without requiring an extension process of the exterior body, while being excellent in the fit of the edge around the leg. There is to do.
  • the present invention that has solved the above problems is as follows.
  • ⁇ Invention of Claim 1> An exterior having a ventral exterior body and a back exterior body, wherein a side edge of the abdominal exterior body and a side edge of the backside exterior body are joined on both sides in the width direction to form a waist opening.
  • Body In a pants-type disposable diaper comprising: an interior body that extends from the center region in the width direction of the abdominal exterior body to the center region in the width direction of the back exterior body;
  • the exterior body on at least one side of the abdominal exterior body and the back exterior body has an inner body joint portion formed by joining an edge on the crotch side of the central portion in the width direction to the interior body.
  • the length in the front-rear direction on the waist side of the joint can be extended to the crotch side, With respect to the exterior body on the at least one side, a portion on the waist side from the interior body joint portion in the interior body is movable to the crotch side.
  • a pants-type disposable diaper characterized by that.
  • the front-rear direction length on the waist side of the exterior body joint portion of the exterior body is extended to the crotch side.
  • the edge of the leg opening located on the side of the body is obliquely upward toward the side edge, and the edge of the leg opening is shaped along the circumference of the wearer's buttocks and the buttocks.
  • Such deformation can be done by hand when using the product, or can be naturally performed as the diaper is pulled up to the waist and attached, or the force applied to the diaper after manufacture (for example, an elastic elastic member to improve fit) Can be carried out by the contraction force or the gravity applied to the interior body). Therefore, at least in the mounted state, the fit of the edge around the leg is excellent. Moreover, it becomes possible to manufacture without requiring an extension process of the outer package.
  • the crotch side portion of the exterior body on at least one side is bent back and forth once or plural times in a zigzag manner, and both side edges thereof are fixed in a folded state, and the non-deployed portion is not
  • a folded portion is formed as a fixed development part
  • the inner body is joined to a portion on the tip side from the fold on the most tip side in the folded portion, and the inner body joint portion is formed,
  • the folded portion is provided with an elongated oblique elastic elastic member that is fixed in an expanded state along the width direction in a state in which the entire width direction is folded, and becomes an oblique direction at the time of mounting.
  • the extension structure of the exterior body is constituted by such a folded portion
  • the edge of the leg opening located on the side of the exterior body in the exterior body when mounted is of course inclined upward toward the side edge. Since the contraction force of the oblique elastic elastic member acts along the edge, the edge of the leg opening fits well around the wearer's buttocks and along the buttocks without looseness.
  • a separation portion including a slit or an elongated opening extending in the width direction from one side of the width direction center to the other side is provided,
  • an elongated slanted elastic elastic member that is fixed in an expanded state along the width direction and that is slanted when mounted is provided. Due to the deformation that the crotch side portion of the spacing portion is separated to the crotch side with respect to the waist side portion, the length in the front-rear direction on the waist side relative to the interior body joint portion can be extended to the crotch side.
  • the extension structure of the exterior body is constituted by such a separation portion
  • the edge of the leg opening located on the side of the exterior body in the exterior body when mounted is of course inclined upward toward the side edge portion. Since the contraction force of the oblique elastic elastic member acts along the edge, the edge of the leg opening fits well around the wearer's buttocks and along the buttocks without looseness. Moreover, it is a very simple structure in which only a slit or the like is provided, there is no increase in material cost, and manufacturing is easy.
  • the at least one side exterior body has at least a stretchability in the front-rear direction, so that the front-rear direction length on the waist side is extendable to the crotch side from the interior body joint portion.
  • the extension structure of the exterior body is thus realized by the extensibility of the exterior body itself, the edge of the leg opening located on the side of the exterior body on the side of the exterior body at the time of wearing becomes obliquely upward toward the side edge.
  • the edge of the leg opening fits well around the wearer's buttocks and along the buttocks. Moreover, it is realizable only by changing a sheet material.
  • the structure with a short length on the back exterior body side of the interior body is suitable for products that do not require much back side absorption performance, such as toilet training pants for infants and incontinence pants for men.
