Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to absorbent pants such as disposable diapers.

[0002]

[Prior art]

 JP-A-57-77204 and 57-117602 disclose brief-type disposable diapers. In this diaper, a liquid-absorbent panel is interposed between a liquid-permeable inner sheet and a liquid-impermeable outer sheet, which are cut in a longitudinal direction, and the inner and outer sheet portions extending from both edges of the panel are provided on both sides. A laminated body in which leg elastic concave members are formed and waist elastic members are attached to both ends in the vertical direction and leg elastic members are attached to the edges of the concave members is folded in two in the vertical direction to form the concave optical member. It is constructed by joining the both side edges except the part.

Japanese Patent Publication No. 4-42017 discloses a pants-type disposable diaper. The diapers shown in FIG. 10 and FIG. 11 of this publication have a liquid-absorbent panel interposed between a liquid-permeable inner sheet and a liquid-impermeable outer sheet, which are cut in a lateral direction, respectively, and extend along the length direction. A laminated body in which a waist elastic member is attached to one side edge portion and a leg elastic member is attached to the other side edge portion along the length direction is folded in two in the lateral direction, and an edge portion opposite to the fold is formed, The laminated body is formed by joining with the edge of the crotch recess formed in the center of the lower end of the laminated body.

[Problems to be solved by the device]

 In the diapers disclosed in JP-A-57-77204 and 57-117602, a crotch recess is formed in order to improve suitability of the diaper to the body. However, the width of the crotch region due to the recess. Becomes narrow and barely covers the thighs of the body. This is because, when the diaper is worn, the leg insertion portion formed by the crotch concave cutout portion does not extend downward from the crotch base bottom surface. Moreover, the liquid-absorbent panel is provided only in the longitudinal central region of the diaper, and is not located along the crotch recess. Therefore, the urine absorption capacity in the crotch region is low, the stool receiving area is small, and the excrement easily leaks from both side edges of the crotch region.

The diaper disclosed in Japanese Examined Patent Publication No. 4-42017 has a crotch recess notch, so that the leg insertion portion is always located below the crotch base, but along the periphery of the recess. The absorbent panel is not in place. Therefore, although the stool receiving area is larger than that of the diaper, the urine absorbing capacity is substantially the same as that of the diaper, and the urine easily leaks from both side edges of the crotch region.

An object of the present invention is to construct a diaper in a pants type in which a leg insertion portion extends downward from a crotch basal plane, and at least the inner surface of the basal plane and the leg insertion section is liquid absorbent. The configuration is to position the panel.

[0007]

[Means for Solving the Problems]

 An article according to the present invention comprises pants having front and rear body parts, a waistline opening and a pair of leg openings, in which a liquid-absorbent panel is interposed between a liquid-permeable inner sheet and a liquid-impermeable outer sheet. In addition, on the premise of disposable absorbent pants in which elastic members that contract in their peripheral directions are attached to their openings, the following characteristics are provided.

That is, the front and rear bodies are formed separately, and a crotch recess is formed in the center of the lower end of the bodies, and the panel is substantially the same in contour shape as the inner and outer surface sheets. The outer peripheral edge portion of the inner and outer surface sheets is formed so as to extend from the outer peripheral edge portion of the panel in the size of the contour so as to join the outer peripheral edge portions of the inner and outer surface sheets, and the crotch notch portion of the body is The pant type has a leg insertion portion that extends downward from the crotch base bottom surface that is the top of the crotch recess notch by joining the edge portions of the crotch and both side edges of the body, respectively. .

[0009]

[Action]

 According to the present invention having the above-mentioned configuration, when the diaper is worn, the entire crotch region including the crotch basal plane is accurately positioned between the crotch of the body, and at least the inner side surface of the leg insertion portion covers the inside of the thigh of the body. To do. Since the liquid-absorbent panel is located also on the groin base and the leg insertion part, urine can be sufficiently absorbed even in these areas.

[0010]

【Example】

 This idea will be described below with reference to the drawings, taking a disposable diaper according to an embodiment of the present invention as an example.

1 to 3, the diaper 1 is configured as a pants type having front and rear bodies 2, 3 to a waist opening 4 and a pair of leg insertion portions (leg openings) 5. The front and rear bodies 2, 3 are composed of a liquid-permeable inner sheet 6, a liquid-impermeable outer sheet 7, and a liquid-absorbent panel 8 interposed between the inner and outer sheets 6, 7. The panel 8 is formed so that the contour shape is substantially the same as the inner and outer surface sheets 6 and 7, and the outer peripheral edge portions of the inner and outer surface sheets 6 and 7 extend from the outer peripheral edge of the panel in the size of the contour. There is.

A crotch recess 9 is formed at the center of the lower ends of the front and rear bodies 2, 3. The front and rear bodies 2, 3 are provided with the crotch recess 9 and the side edge portions 10 and the joining lines 11 and 12 by a fusion bonding means under heating or under the action of ultrasonic waves while leaving the edges slightly. They are joined together. In the diaper 1 configured in this manner, the leg insertion portion extends downward from the crotch base bottom surface 9a that is the top surface of the recessed portion 9. The joining line 11 may be a curve as shown in A, B and C of FIG. The size, shape and radius of curvature of this curve can be appropriately determined depending on whether the diaper is for adults or infants.

The elastic members 13 and 14 contracting in the circumferential direction are interposed between the edges extending from the panel 8 around the waist and legs of the inner and outer sheets 6 and 7, and the edges are hot-melt adhesive. Alternatively, it is closed by the fusion means.

Both the side edges of the front and rear bodies 2, 3 and the lower edges around both legs are inclined with respect to the axis 15, but the both side edges are vertical lines parallel to the axis 15, and the lower edges around both legs are horizontal to the axis 15. It may be formed on each line.

As a constituent material of the diaper 1, a material generally known as that of a known diaper can be used. For example, the inner sheet 6 is a nonwoven fabric, preferably a stretchable nonwoven fabric, the outer sheet 7 is a plastic film, preferably a stretchable nonwoven fabric laminated with a stretchable elastomer film on the inner surface, and the panel 8 is a fluff pulp with a super absorbent polymer. Natural or synthetic rubber can be used for the mixed material and the elastic members 13 and 14, respectively.

[Effect of device]

 According to the article of the present invention configured as described above, the width of the crotch region can be widened even when the leg notch recesses are formed on both sides of the crotch region, and at least the inner thigh of the body is formed. Since the urine can be absorbed by the liquid-absorbent panel in the crotch region, it is possible to eliminate the above-mentioned drawbacks of the conventional diaper.
