[0002]
Problems to be solved by the prior art and the invention
Conventionally, as a disposable disposable diaper, a liquid-permeable top sheet, a liquid-impermeable back sheet, and a liquid-retentive absorber interposed between these two sheets are provided. Diapers having an abdominal part located on the back side and a dorsal part located on the dorsal side are widely used. A waist band portion is provided in series, a band fastening portion is provided at a tip portion of at least one of the left and right waist band portions, and a diaper fastening portion is provided on both sides of the abdominal side. After the left and right waistband portions are fastened to the wearer's abdomen by the band fastening portion, the abdomen is fastened to the waistband portion by the diaper fastening portion and worn. I will do it Which are without the is known (see Patent Documents 1 and 2).
[0003]
Such a waistband type disposable diaper has an advantage that a wearer can wear it in a standing position by himself, and also peels off the abdominal part from the waistband part, and the left and right waistband parts It is also possible to urinate or defecate while keeping the affixed to the wearer's abdomen.
However, in conventional diapers, when urination or defecation is attempted with the left and right waistbands fastened to the abdomen, the abdomen peeled off from the waistbands comes into contact with the urinal, which is very difficult. It is unsanitary and may have to change diapers due to contact with water or waste in the toilet bowl.
[0004]
By the way, especially in a nursing care site such as a nursing care facility, a diaper is often worn by a caregiver instead of a wearer. In such a case, the care receiver often replaces the diaper while holding the hand on the wall or the handrail, and it is not easy to mount the diaper particularly on an elderly man with a bent back. In addition, some people find it difficult for the caregiver to see the pubic area when worn.
In view of such circumstances, the inventors of the present invention have considered that the diaper should be worn in the opposite direction to the conventional one.When the diaper is worn in the opposite direction, the left and right waistbands are fastened. When urination or defecation is performed in a state where the diaper is kept, the possibility of bringing a part of the diaper into contact with the toilet or the water in the toilet further increases.
[0005]
Patent Document 3 describes a disposable diaper in which two tape-shaped members having a fastening portion are provided on both sides in the diaper longitudinal direction. However, the tape-shaped member itself requires rigidity or bending resistance, and it is not easy to fold a portion extending from the diaper body toward the back sheet. In addition, since a tape-shaped member different from the diaper body is used, it cannot be manufactured at low cost. Further, Patent Literature 3 does not disclose anything about temporarily disposing a disposable diaper in a state in which the disposable diaper is folded in the longitudinal direction such that the surfaces on the back sheet side overlap each other.

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described based on preferred embodiments with reference to the drawings.
A disposable diaper 1 as one embodiment of the present invention is an adult diaper that can be worn while standing, and as shown in FIG. 1, a liquid-permeable top sheet 2 and a liquid-impermeable back sheet. 3, and a liquid-retentive absorber 4 interposed between the sheets 2 and 3 and is formed substantially vertically. The term “substantially vertically long” means that a portion other than the waistband portion is vertically long. The longitudinal direction of the diaper is the same direction as the longitudinal direction of the portion excluding the waistband portion.
[0011]
The absorbent body 4 is sandwiched and fixed between the top sheet 2 and the back sheet 3, and the waist part 5 and the leg part 6 in the peripheral part of the absorbent body 4 have waist parts for fitting each part to a diaper wearer. An elastic member 51 and a leg elastic member 61 are provided.
A three-dimensional guard 7 is formed on each of the left and right sides in the longitudinal direction of the disposable diaper 1. A three-dimensional guard elastic member 71 is disposed at a free end of the three-dimensional guard 7 to form a gather.
[0012]
The topsheet 2 has a rectangular shape slightly wider than the entire width of the absorber 4, and is disposed on the center in the width direction of the backsheet 3 formed in an hourglass shape. A portion of the back sheet 3 extending outward from both left and right edges of the top sheet 2 is covered with a sheet material 72 for forming the three-dimensional guard 7.
The sheet material 72 for forming the top sheet 2, the back sheet 3, the absorber 4, and the three-dimensional guard 7 constitutes the diaper main body portion 8.
[0013]
One side in the longitudinal direction of the disposable diaper 1 (a side having a waistband portion on the left and right sides, hereinafter referred to as abdomen for convenience) A left and right side edge portions (more specifically, the diaper body portion 8 Waist bands 10, 10 are respectively provided continuously on both side edges), and a band fastening portion 11 is provided at a distal end of at least one of the left and right waist bands 10, 10. . In addition, diaper fastening portions 21 and 22 are provided on both side portions of the other portion in the longitudinal direction (hereinafter referred to as a back side portion for convenience) B, respectively.
Then, as shown in FIG. 2, the left and right waistband portions 10 a and 10 b are fastened on the back side of the wearer by the band fastening portion 11, and then the diaper fastening portions 21 and 22 are used to secure the back side portion B. Can be fastened to the mutually connected waistband portion 10 to be worn.
The one part and the other part in the longitudinal direction of the diaper are generally a region from each edge in the diaper longitudinal direction to about 1/3 of the entire length of the diaper, and a region between these is a crotch part.
[0014]
The disposable diaper 1 has flap portions 20 on both sides of the back side portion B.
As shown in FIG. 3, the flap portion 20 is a portion of the back side portion B that is located outside of the position of each of the left and right side edges 41 of the absorber 4 in the diaper width direction. The portion 20 is mainly composed of a sheet material 72 for forming a three-dimensional guard and a top sheet 3 extending outward from the side edge 41 of the absorber 4, and both sheets near the base end (the position of the side edge 41). A topsheet 2 is further interposed between 72 and 3.
[0015]
Each of the flap portions 20 includes a first fastening portion 21 as a diaper fastening portion, which is located near a waist edge (one end on the back side B side in the diaper longitudinal direction) 9 of the back portion B, A second fastening portion 22 is provided on the diaper crotch portion C side of the first fastening portion 21, and is provided between the first fastening portion 21 and the second fastening portion 22 in each flap portion 20. A recess 25 is formed.
[0016]
The flap portion 20 needs to be made of a flexible material so as to be easily bent at least in the width direction of the diaper in the longitudinal direction and the width direction.
The flap portion 20 in the present embodiment is made of a laminated sheet of a water-repellent nonwoven fabric forming the sheet material 71 and a resin film forming the back sheet 3, and is easily bent and has a very small repulsion force after bending.
[0017]
The sheet material forming the flap portion 20 is flexible because the flap portion 20 is bent so that the first fastening portion 21 can be easily turned in the direction opposite to the direction in which the second fastening portion 22 faces. It is preferable that the bending rigidity as an index of the property is 10 to 80 g, particularly 15 to 60 g. If the resistance value is less than 10 g, the strength of the fluff 20 decreases, and there is an inconvenience such as tearing.
[0018]
(Method of measuring bending stiffness)
The measurement was performed in accordance with JIS L1096-1990 E method (handle ometer method). However, when measuring the bending stiffness, the flap 20 starts from a portion as close as possible to both the end (inner end) 23 of the first fastening portion 21 on the center side in the diaper width direction and the deepest portion 25a of the concave notch 25. A 4.5 cm long by 4.5 cm wide test piece was cut out, and the flexural rigidity of the test piece in the direction corresponding to the diaper (product) width direction (the transverse direction of the sample) was measured. In addition, the slot width was measured as 2 cm.
[0019]
Further, the first fastening portion 21 is provided closer to the waist edge 9 than the position of the edge 42 of the absorber 4 in the diaper longitudinal direction, so that the flap portion 20 is not only in the diaper width direction but also in the diaper longitudinal direction. This is preferable because it becomes easier to bend in the direction, and it becomes easier to direct the first fastening portion 21 to the side opposite to the second fastening portion 22.
[0020]
As shown in FIG. 3, the concave notch 25 in the present embodiment is located closer to the center in the diaper width direction than the end (inner end) 23 of the first fastening portion 21 on the center side in the diaper width direction. Further, in the diaper longitudinal direction, it is formed at substantially the same position as the position of the end portion 42 of the absorber 4 in the longitudinal direction.
The depth D of the concave notch portion 25 (the linear distance in the diaper width direction from the outer edge portion 20a of the flap portion to the deepest portion 25a of the concave notch portion 25, see FIG. 3) is such that the first fastening portion 21 is secondly fastened. From the point that it is easier to direct the part to the opposite side to the part 22, the linear distance L1 in the diaper width direction from the outer edge part 20a to the position of the end part 23 of the first fastening part 21 on the center side in the diaper width direction ( It is preferable that the depth D of the concave notch portion 25 is 0.1 cm or more, especially 0.5 cm or more deeper than that of the outer edge portion 20a (see FIG. 3). Is preferably 15 to 85%, more preferably 25 to 75% of the linear distance in the diaper width direction from the position to the side edge 41 of the absorber (see FIG. 3).
[0021]
However, it is sufficient that the depth D of the recessed portion 25 is deeper than the end of each of the first and second fastening portions on the outer side in the diaper width direction. If such a condition is satisfied, there is a temporary fixing effect because a turning base point is formed. However, it is preferable to be deeper than the center in the width direction of each of the first and second fastening portions.
FIG. 6 shows another preferred example of the concave notch 25 provided between the first and second fastening portions. The depth D of the concave notch 25 shown in FIG. 6 is less than the depth L1, and the depth D is 30 times the opening length L3 of the concave notch at the flap outer edge 25a (see FIG. 6). About 100%.
The radius of curvature at the deepest portion 25a of the concave notch 25 is preferably 1 cm, particularly 2 cm or more, from the viewpoint of preventing breakage of the flap due to concentration of stress.
[0022]
The first and second fastening portions 21 and 22 each constitute a flap 20 of a convex member of a mechanical fastener in which a large number of anchor-shaped or hook-shaped male engaging members are arranged on the surface of the base sheet. It can be formed by bonding to a sheet material to be formed. Examples of the convex member of the mechanical fastener include “Magic Tape (registered trademark)” (manufactured by Kuraray), “Quicklon (registered trademark)” (manufactured by YKK), and “Majicross (registered trademark)” (Kanebo Bell Touch) Commercially available products such as a product manufactured by Toshiba Corporation can be used. Similarly, the band fastening portion 11 can be formed by joining the convex member of the mechanical fastener to the sheet material forming the waistband portion.
