2. Description of the Related Art Conventionally, techniques for providing elastic elastic members around the legs and the waist to improve the fit of disposable diapers are well known. Further, a technique of providing a tape-shaped fastener on the side edge of the back body to connect the front body and the back body is also well known. The fastener is usually sized so that it can be picked with one hand for the purpose of enabling one-handed operation and minimizing the cost of the diaper. As a means for connecting the fastener to the front body side, a sticking mechanism using an adhesive or a locking mechanism known by the trade name Velcro is used.

[0003]

[Problem to be solved by the invention] In this kind of diaper,
There is an advantage that the fastener operation is extremely easy.
However, on the other hand, the area of attachment or locking of the fastener to the front body is small, and the interval between the waist and leg elastic elastic members arranged vertically at the back body side edge is large, and Since the longitudinal directions of these members are different, even when the zipper is pulled in the waist direction when the diaper is worn, it often happens that the elastic members do not become equally moderately stretched. In such a case, there is a problem that the fit around the torso or around the legs is deteriorated, which sometimes causes body fluid leakage. In addition, after wearing, there is a problem that the superimposed front and rear bodies move and, for example, the leg circumferences tend to open, which also causes body fluid leakage.

In this invention, a wing portion having elastic means in the waist direction and elastic means in the leg direction is provided on the side edge of the back of the diaper. Can be in a moderately stretched state,
It is an object to solve the conventional problem.

[0005]

The gist of the present invention to solve the above problems is as follows.

[0006] In this invention, the liquid-permeable surface sheet - and DOO, liquid-impermeable back sheet - and DOO, these two sheets - and a absorbent body interposed between the bets, the front and rear ends of the absorber On both sides,
And a first elastic elastic member extending from at least one of the abdominal and dorsal flaps to a waist direction of the dorsal flap, and A left and right leg flap is provided outside both side edges of the crotch portion of the absorber, and a left and right wing portion is provided outside the both side edges of the back body to cover the waist side. The first elastic elastic member is provided on the leg flap. a second elastically stretchable members extending your <br/> diaper leg-surrounding direction be separate from the,
In addition, the vicinity of the outer edge of the wing portion is connected to the front body.
It is assumed that disposable diapers are provided with means .

This invention is based on the premise that the wing portion is formed separately from the first elastic member and extends in parallel with an extension line of the elastic member. 3 elastic elastic members, and the first, second and third elastic elastic portions
Separate from the material, and inclined from the outer edge of the wing portion toward the diaper crotch portion to extend in the vicinity of the second elastically expandable member.
And a fourth resilient and elastic members for standing, and said third contact
And the connecting means is positioned on the long axis of the fourth elastic member.
It is characterized by having been done.

[0008]

In the diaper according to the invention, when the diaper is worn, the diaper is mainly pulled by the third elastic expansion and contraction member .
The same time as it is possible to moderately stretch the first elastic stretchable member
By pulling the fourth elastic member, the second elastic member can be extended moderately, and each elastic member is connected to the front body via each connecting means provided on its long axis. In addition, the diaper hardly slips around the waist and legs in the worn state.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of this invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a disposable diaper 1 according to the present invention.
FIG. 2 is a perspective view showing the assembled state in a worn state. Diaper 1
Has a front body 2, a back body 3, and a crotch portion 4 interposed between the both bodies 2, 3, and wing portions 5 on the left and right sides of the back body 3 are detachably attached to the front body 2. , Opening around the waist 6
And an opening 7 around the leg.

FIG. 2 is a plan view showing the diaper 1 shown in FIG. The diaper 1 has a water-permeable top sheet 10, a water-impermeable back sheet 11, and a rectangular absorber 12 interposed between these two sheets 10, 11, and outside the front and rear edges 13, 14 of the absorber 12. The front and back sheets 10 and 11 are joined to form an abdominal flap 15 and a back flap 16, and the front and back sheets 10 and 11 also extend outside the left and right side edges 17 of the absorber 12. Are joined to form a flap 8 around the leg. The rear body 3 is provided with a wing 5 to which front and back sheets 10 and 11 extending from the side edge of the absorber 12 are joined. The back side flap 16 is provided with a ribbon-like elastic elastic member 21 interposed between the front and back sheets 10 and 11 and attached to at least one of the sheets under extension in the waist direction. An elastic elastic member 22 extending in the front-rear direction of the diaper 1 is similarly attached to the leg-around flap 18. Although this member 22 can be arranged linearly in the front-rear direction, it is preferable that at least both ends be bent outward as shown in the figure, so that the member 22 can be easily fitted around the legs.

The wing portion 5 includes a ribbon-like elastic elastic member 24 extending on the extension line of the elastic elastic member 21 in the waist direction (horizontal direction in the figure) and extending to the vicinity of the outer edge 23 of the wing portion. An elastic elastic member 25 in the form of a ribbon, which is arranged to be inclined in the direction of the crotch portion 4, is attached under extension. Preferably, the direction of the inner end of the inclined elastic elastic member 25 is made substantially the same as the direction of the end of the curved leg elastic member. On the front side near the outer edge 23, an adhesive 26 is applied on the long axis of the elastic member 24, 25 including the respective extension lines, and the back sheet 11 of the front body 2 is applied.
It is designed to be removably attached to.

[0013] When wearing the diaper 1 and bonded to the outer edge 23 near the member 24 by first stretching the resilient and elastic members 24 in the waist direction in the wing portions 5 on the front body 2, co
Then, the elastic elastic member 25 is extended diagonally upward, and the vicinity of the outer edge 23 is attached to the front body 2. By doing so, the waist elastic elastic member 21 and the leg elastic elastic member 22
Can be extended to a moderately stretched state individually,
Diaper 1 fits the body well. During the wearing, since these elastic members 21 and 22 are separately attached to the front body 2 on the extension lines, so to speak, the expansion and contraction of each of the elastic members rarely directly interfere with each other, and the exercises are performed intensely. The diaper 1 is hard to come off.

The wing portion 5 may be formed by extending the front and back sheets 10 and 11 from the side edge 17 of the absorbent body 12 and joining them together. However, separate members prepared in the form of wings may be used. It can also be formed by bonding to back sheet 11. In the latter case, it is not always important to configure the wing section with two sheets,
It can be done with one sheet. When the wing portion 5 is a laminated two sheets, the elastic elastic member 2
Preferably, 4, 25 are interposed between the two sheets. Each of the elastic elastic members 24 and 25 can be an appropriate number of elastic ribbons. Also, the elastic elastic member 25
Can give a difference between the plurality of elastic ribbons in the inclination in the crotch 4 direction. Each of the elastic members 24 and 25 can have an appropriate length, and it does not matter whether the elastic members extend to the outer edge 23 or not. Therefore, the length is long, and the adhesive 26 may be applied on the elastic members 24 and 25 in the vicinity of the outer edge 23;
The adhesive 26 may be applied on the extension line of 4,25. The adhesive 26 can also be applied continuously between the members 24 and 25 in the front-back direction of the diaper.

A conventional material may be used for the diaper 1. For example, a nonwoven fabric or an open plastic sheet is used for the top sheet 10, a plastic sheet such as polyethylene is used for the back sheet 11, and pulverized pulp is used for the absorber 12. And a mixture thereof with a superabsorbent polymer. The material of the wing portion 5 may be appropriately selected from materials usable for the top sheet 10 and the back sheet 11.

[Effect of the invention] The diaper according to the invention is attached to the wing section.
A third telescopic cooperating with the first elastic telescopic member in the waist direction;
Elastic telescoping member and legs around the legs inclining in the crotch direction
Fourth elastic extension cooperating with the second elastic extension member in the direction.
The caregiver pulls the wing
Only around the torso and legs of a wearer such as an infant.
The diaper can be worn as if it were fitted. I
The first and third elastic members and the second and third elastic members
The fourth elastic member is disposed separately from the
Because they do not directly interfere with
Even if you exercise hard, the diapers are less likely to shift.

[0017] Also, first, second, third and fourth elasticities
Since each member is separate, efficient
Can be placed and save on those materials.
