Definitions
- the present invention relates to a disposable diaper that absorbs and holds excrement.
- a pair of tape fasteners are attached to the wings around the rear waist region, and the tape tape is detachably secured to the outer surface around the front waist region. Is attached.
- the second wing portion around the rear waist is formed of an inner layer sheet and an outer layer sheet having elastic elasticity.
- stretchable fiber nonwoven fabric, elastomer film, and rubber film are used for the inner and outer layer sheets.
- the inner layer sheet and the outer layer sheet are joined via an elastic material having a rubber-like elasticity having a higher elongation stress than the sheets in a state where the sheets overlap each other.
- the tape fastener has a fixed portion fixed to the outer end portion of the second wing portion and a free portion extending laterally outward from the fixed portion.
- the hook of the mechanical fastener is attached to the free part of the tape fastener.
- a loop of mechanical fastener is attached to the outer surface of the target tape.
- the second wing part in the rear waist area is overlapped with the outside of the front waist area, and the free part of the tape fastener is fastened to the outer surface of the target tape to surround the front and rear waists.
- a diaper in which the front and rear waistline areas are connected is formed with a waistline opening and a pair of leg openings.
- the inner and outer layer sheets forming the second wing part are joined in an unstretched state via an elastic material, so that no gathers are formed on the inner and outer layer sheets. A decrease in wearing feeling due to gathers can be prevented.
- Patent Document 1 Japanese Patent Laid-Open No. 10-328237
- the diaper disclosed in Patent Document 1 uses an elastic fiber nonwoven fabric, an elastomeric film, or a rubber film for the inner and outer layer sheets forming the second wing portion in the region around the rear trunk.
- the elastic fiber nonwoven fabric contains an elastomer material as well as the film
- the inner and outer layer sheets that come in contact with the wearer's skin have a sticky feeling that is characteristic of rubber, and the inner and outer layers have a high frictional force.
- the layer sheet sticks to the wearer's skin, giving the wearer an unpleasant feel, and the moisture permeability of the second wing around the rear waist is significantly reduced, resulting in the second generation of water vapor generated when sweat evaporates. It cannot be released from the wings to the outside of the diaper, and the mud inside the diaper cannot be eliminated.
- An object of the present invention is to provide a disposable diaper capable of releasing water vapor generated when sweat evaporates without giving an unpleasant feel to the wearer from the wing part.
- the premise of the present invention to solve the above-mentioned problems is that the front waistline region and the back waistline region, and a crotch region positioned between these waistline regions, A disposable diaper having a pair of first wings extending laterally outward from both sides and a pair of second wings extending laterally outward from both sides of the rear waist region.
- the feature of the present invention based on the premise is that at least the second wing portion of the first and second wing portions is formed of an elastic composite sheet that is elastically expandable and contraction, and the composite sheet A breathable stretchable plastic film having a first opening on the contact side and a second opening on the non-skin contact side and formed with a plurality of ventilation pipes extending in the thickness direction of the composite sheet; and It is made of a ventilated heat-fusible fiber non-woven fabric in which a plurality of gathers that are partially bonded to both surfaces via a heat-sealing portion and undulate in the thickness direction of the composite sheet are formed.
- the fiber nonwoven fabric that forms the wing is in contact with the skin of the wearer.
- the stickiness and sliminess are not felt, and the water vapor generated when the sweat evaporates can be discharged from the vent pipe to the outside of the diaper.
- the vent pipe whose area of the second opening is smaller than that of the first opening is the first opening force toward the second opening.
- the surface tension in the vent pipe acts more strongly in the vicinity of the second opening than in the vicinity of the first opening.
- the vent pipe is formed in the plastic film in a range of 1080 80 cm 3 , and the total area of the first openings is that of the plastic film. It is in the range of 10-20% of the area.
- the joint between the fiber nonwoven fabrics is located inside a part of the vent pipe, and the joint between the fiber nonwoven fabrics is located inside.
- the number of the vent pipes in the range of 1.5 to 10% of the total number of the vent pipes.
- the fiber form of the fiber nonwoven fabric is maintained, and the fiber density of the fiber nonwoven fabric excludes the heat fusion part. Higher than that of the remaining part of the nonwoven fabric.
- the capillary phenomenon in the heat-sealed portion acts more strongly than that in the remaining portion, and sweat that has permeated into the remaining portion of the fiber nonwoven fabric moves toward the heat-welded portion.
- the length dimension of the wing part formed from the stretchable composite sheet when not stretched is 100%, and the length dimension is 120%.
- the wings were stretched so that the extensional stress in the transverse direction when the wings were stretched to 1.5% was 1.5%.
- the lateral stress of the wing is in the range of 3.0 to 10. ON.
- the thickness of the plastic film is in the range of 0.3 mm
- the basis weight of each of the fiber nonwoven fabrics is in the range of 20-60 g / m 2
- the thickness of each of the fiber nonwoven fabrics is 0. 1—in the range of 0.5 mm
- the density of each of the fiber nonwoven fabrics is in the range of 0.04-0. 6 g / cm 3 .
- the second wing portion of the first and second wing portions is formed of an elastic composite sheet that can elastically expand and contract, and the composite sheet is a breathable elastic plastic. It is made of a breathable heat-fusible fiber nonwoven fabric that is partially bonded to both sides of the film and plastic film, and when the diaper is worn, the fiber nonwoven fabric located on the skin contact side comes into contact with the wearer's skin. Even though the wings are elastic and stretchable, the wings will not stick to the skin, and the wearer will not feel uncomfortable.
- the wing part touches the skin and the wing part has a sticky feeling and a slimy feeling peculiar to rubber. Sometimes the wearer does not feel uncomfortable.
- the surface tension in the vent pipe is closer to the second opening than to the first opening. Because it works strongly, sweat that has entered the first opening can easily be directed to the second opening from the wings to the outside of the diaper, and the wet state on the skin contact side of the wings Can be quickly resolved.

Because it is difficult to do.
- FIG. 7 is a perspective view of the diaper 1A shown in the mounted state.
- An example of the procedure for parents and caregivers to wear the diaper 1A to the wearer is as follows. Unfolded diaper 1A put the wearer's buttocks on his back on 1A, hold the front waist area 8 and bend the crotch area 9 of the diaper 1A, and put the front waist area 8 on the wearer's abdomen. Put on the top. Next, the wing part 14 is bent while holding the tape fastener 19 with a finger so that the second wing part 14 is positioned on the wearer's abdomen.
