Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pants-type diaper,
More specifically, the present invention relates to a pants-type disposable disposable diaper having a waist opening and a pair of left and right leg openings formed by joining both side edges of a front body and a rear body.

[0002]

2. Description of the Related Art The standard form of a pants-type disposable paper diaper of this kind is to join both side edges of a front body and a back body,
It has a waist opening and a pair of left and right leg openings.

[0003] In recent years, many disposable disposable diapers are provided with a so-called post-processing tape so that the disposable diaper can be easily disposed of.

[0004] This post-processing tape is generally provided on the back body, and the free end of the tape fastener is not used as an outerwear portion used when disposing the diaper. The put tape fastener is extended, and the outer part of the tape fastener is positioned over the waist opening so as to be put on the front body so that the rolled state is not released.

[0005] A typical example of this is disclosed in Japanese Utility Model Publication No. 8-10305 having a post-processing tape having a three-layer structure.

[0006]

However, this kind of post-treatment tape does not have a negligible percentage of the cost of the product, and the material of the diaper body is effectively used as much as possible due to the increase in environmental protection. There is a request to use it.

Further, when using a post-treatment tape, since the post-treatment tape is located at one position on the rear body of the disposable diaper body, the direction in which the post-treatment tape is rolled is restricted, so that it may be inconvenient to start over.

Further, if the adhesive at the tip end of the tape fastener comes off, or if an attempt is made to fix the adhesive again after that, the adhesive strength of the adhesive may be reduced and the adhesive may not be fixed.

On the other hand, since excrement easily leaks from the pair of left and right leg openings during the post-processing, there is a post-processing form in which both sides are folded inward and then rounded in the front-rear direction. In this case, since the tightening force cannot be increased, such a post-processing form cannot be taken.

[0010] Accordingly, a main object of the present invention is to provide a structure capable of reducing costs, effectively utilizing the material of the diaper main body, and a structure capable of simplifying post-processing operations.

[0011]

The torso region T can be conceptually divided into a “waist” W and a “lower waist” U. The length in the vertical direction varies depending on the size of the product, but the waist portion W is 15 to 40 mm and the lower waist portion U
Is 45 to 220 mm. The “crotch region” L refers to the entire region of the range in which the leg opening is formed, that is, the entire length range from the beginning of the leg opening on the front body side to the beginning of the leg opening on the back body side. The “central portion” means an intermediate region excluding a side portion including the center line of the product. The “side portions” mean both side portions in the waistline region T.

Between the nonwoven fabrics of the outer sheet 5, a plurality of waist elastic members 7 for improving the fit of the waist opening edge to the waist portion W enhance the fit around the waist to the lower waist U, and before and after urine. A plurality of lower back elastic members 8 for preventing leakage are fixed respectively. As the elastic members 7 and 8, for example, a natural rubber thread or a synthetic rubber thread having an appropriate thickness and cross-sectional shape can be used.

As shown in FIG. 2, the absorbent element AB is made of, for example, a non-woven fabric or the like, and is made of a liquid-permeable top sheet 1 that directly touches the wearer's skin, a plastic film such as polyethylene, or a water-repellent treatment. If necessary, an absorbent core 3 mainly composed of cotton pulp is interposed between the liquid-impervious back sheet 2 made of non-woven fabric and absorbent papers 3A and 3B.
, And the peripheral portion is bonded and integrated with, for example, a hot melt adhesive. In the illustrated example, a second sheet 6 made of a nonwoven fabric or the like is provided below the liquid-permeable top sheet 1.

On the other hand, on both sides of the absorber element AB, barrier cuffs 20 around the legs are provided. This barrier cuff 20 is folded back into a doubled barrier sheet 21.
The base end of the inner surface of the barrier sheet 21 is fixed to the back sheet 2 with a hot melt adhesive, and the extending portion of the outer surface of the barrier sheet 21 is It is fixed with an adhesive or the like.

In the vicinity of the free edge of the barrier sheet 21, one or a plurality of tip-end elastic members 22 made of a band-like rubber or a thread-like rubber are fixed with a hot melt adhesive or the like under elongation. Further, as shown in the figure, the barrier cuff 20 has an outward portion formed by turning the distal end outward at substantially the center of the free portion that stands up, and an inward base end side (root side) where this return is not made.
One or more base end elastic members 22A are fixed with a hot melt adhesive or the like under elongation.

In accordance with the present invention, as shown in FIGS.
Is folded back to the outside of the diaper beyond the waist opening WO of the outer sheet 5 to form a storage bag portion 40 having an opening 42 outside the diaper. The shape of the storage bag portion 40 and the direction of the opening portion 42 are not particularly limited, but preferably, as shown in the drawing, the inner surface sheet 9 of the back body B is placed outside the diaper outside the waist opening WO of the outer surface sheet 5. It is folded down, and the tip of the folded portion 41 is extended to the portion corresponding to the lower waist in the range from the lower end of the waist portion W to the start end of the leg opening, particularly preferably 60 to 120 mm in length.
Preferably, both sides of the folded portion 41 in the diaper width direction are fixed to the outer surface of the diaper, and the storage bag portion 40 having the downward opening portion 41 is preferably formed.

As shown in the figure, both side portions of the folded portion 41 are joined to the joint portions 30 by joining both side edges of the front body F and the back body B.
When performing heat seal bonding, it is desirable to perform heat seal bonding simultaneously with these.

When the disposable diaper is disposed of, as shown in FIGS. 6 and 7, the crotch portion L on the side having the storage bag portion 40 is rolled up to the vicinity of the storage bag portion 40 while being rolled toward the waist opening WO. By pushing the winding part RL into the storage bag part 40, the diaper can be held in a rolled state. Thereby, the disposable diaper can be discarded without being soiled.

As described above, the disposable diaper according to the present embodiment uses the inner surface sheet 9, which is an essential material of the diaper, to form the storage bag portion 40 that is opened on the outer surface of the diaper. Significantly cheaper than type post-treatment tape. Therefore, according to the present embodiment, material costs can be remarkably reduced as compared with the case where a conventional post-processing tape is provided, and requirements for environmental protection can be satisfied. Further, in this example, the storage bag portion 40 covers the waist elastic member 8 and the lower waist elastic member 7 of the back body B, so that the appearance is clear.

Although the storage bag section 40 of this embodiment is provided on the back body B, the inner surface sheet 9 of the front body F is folded outward beyond the waist opening WO of the outer sheet 5 so that the outer surface of the front body F can be folded. At the front and rear bodies F and B. When provided on the front and rear bodies F and B, there is an advantage that the user does not need to worry about the direction of winding up when disposing. In addition, the storage bag section 40 of this example is connected to the outer sheet 5.
When the bag is adhered to the main body so that it can be separated (the meaning of this term will be described later), the bag does not flicker and has a clean appearance.

<Second Embodiment> In a second embodiment, as shown in FIGS. 8 and 9, a portion of the inner surface sheet 9 corresponding to the lower waist portion U of the folded portion 41 extends along the circumferential direction. Reference numeral 47 denotes a mode in which a large number are provided at appropriate intervals.
In order to provide the folded portion elastic member 47, the folded portion 41 has a double structure with the back sheet 43 as shown in the figure, and the elastic member 47 can be arranged between them.

Since the folded back elastic member 47 has the function of enhancing the fit of the lower waist U when the diaper is worn, similarly to the above-described lower waist elastic member 7, the above-described lower waist elastic member 7 is omitted. You can also. Further, as shown in FIG. 10, since the storage bag portion 40 is contracted by the folded portion elastic member 47, there is also an advantage that the winding portion pushed into the bag portion 40 at the time of disposal is more reliably held.

The folded portion elastic member 47 may be provided on the entire width direction as shown in the figure, or may be provided only on the center portion in the width direction or only on both side portions excluding the center portion in the width direction.

<Third Embodiment> In a third embodiment, as shown in FIGS. 11 and 12, the outer sheet 5 forming the outer surface of the diaper is folded back at the waist opening WO to the inner surface of the diaper. The present invention relates to a pants-type diaper including a leak guard sheet 50 in which a base end portion 51 is fixed to an inner surface of the diaper and a distal portion is a free portion 52. Note that the leak guard sheet 50 in the illustrated example is used.
Is provided only on the back side, that is, only on the inner surface of the back body B, but in the present invention, a similar guard sheet may be provided instead or together with the inner surface of the front body F.

Now, the leak guard sheet 50 of the present embodiment is
The rear body side portion of the outer sheet 5 is folded back over the waist opening WO of the inner sheet 1 toward the inner side of the diaper, and a base end portion 51 of the folded portion 50 up to the upper end position of the absorbent element AB is inside the diaper. The front surface, in this case, is fixed to the liquid-permeable top sheet 1, and a portion on the distal end side thereof is formed as an unfixed free portion 52.

In this embodiment, the existing leak guard sheet 5
0 is used to form a storage bag portion inside the diaper. Therefore, in the present invention, the base end portion 51 of the leak guard sheet 50 is fixed to the inner surface of the diaper so as to be separable. Here, the term "separable" in the present invention means that the fixing means is originally simply overlapped, and is weakly fixed or fixed in a scattered manner. It is intended to include both states in which the sheet can be easily peeled off and separated from the sheet on the inner surface of the diaper.

Preferably, the length 50L of the folded portion 50 including both the fixed base end portion 51 and the free portion 52 in the vertical direction of the diaper is 60 mm or more, and both side portions thereof are fixed to the inner surface of the diaper. Free part 52 of 50
Has a vertical length of 10 mm or more. In particular, when the both side portions of the leak guard sheet 50 are heat-sealed at the joint portion 30 at both side edges of the front body F and the back body B, it is preferable that the two sides be simultaneously heat-sealed together.

At the time of disposal of the diaper, as shown in FIG. 13, both joints 30 on both sides of the diaper are cut off, and both sides of the front body F are folded inward as shown in FIG. 14, and this is folded as shown in FIG. Then, wind up toward the waist opening WO side of the back body B. On the other hand, before or after, the free portion 52 of the leak guard sheet 50 is pinched and the base end portion 51 is peeled off leaving both side portions to form the storage bag portion 55, and FIG.
As shown in (2), by pushing up the winding portion RL into the bag portion 55, the waste can be wrapped and held in a rolled state. Thereby, the diaper can be discarded without being stained. In particular, by setting the length of the folded portion 50 in the vertical direction of the diaper to be 60 mm or more, the length of the storage bag portion 55 in the vertical direction can be formed to be 60 mm or more, and a sufficient size for housing the roll-up portion RL can be secured. By setting the length of the free portion to 10 mm or more, it is easy to pinch when peeling, and a sufficient leak guard effect can be exhibited.

Such a leak guard sheet 50 is conventionally provided as a waist circumference leak-proof sheet on the inner surface of the diaper. The present invention is an improved one which is also used as a disposal means. Therefore, since a separate member for disposal such as a post-treatment tape is not required, material costs can be remarkably reduced, and requirements for environmental protection can be satisfied.

<Fourth Embodiment> In a fourth embodiment, as shown in FIG. 17, both sides of the rear part of the diaper are tightened around the waist according to the present invention. The dual-purpose tape fasteners 60 are provided respectively.

The tape fastener 60 according to the present invention
As shown in FIG. 18, the distal end portion has an engaging member 61 capable of engaging with the nonwoven fabric forming the outer sheet, and the proximal end portion 6 has
3 is fixed to the side portion, and at least a portion 62 between the distal end portion and the proximal end portion has elasticity. Specifically, an engaging member 61 (eg, a hook member having a large number of mushroom-shaped hooks) is fixed to the back surface (diaper side surface) of the distal end portion of a base tape 62 made of an elastic elastic material such as natural rubber or synthetic rubber. At the same time, the rear surface of the base end (diaper side surface) can be fixed to the outer surface of the diaper with the adhesive 63.

The tape fastener 60 in this embodiment
As shown in FIG. 19, the diaper is provided for the purpose of preventing the diaper from slipping and falling due to the weight of the diaper and the deformation of the absorber during mounting.
By stretching 0 and bringing it into engagement with the front body F side beyond both side edges 30, the degree of tightening in the diaper waist direction can be adjusted.
Further, since the tape fastener 60 expands and contracts as described above, there is also an advantage that the tightening in the waist direction does not work in a fixed manner, and the tape fastener 60 can be surely fitted according to the movement of the wearer.

When the diaper is discarded, as shown in FIG. 20, the crotch portion L is rolled up to the front body F side, and as shown in FIG.
The diaper can be held in a rolled-up state by extending the joints 60 beyond the joints 30 on both sides and joining and fixing the diapers to the outer surface of the rolled-up portion RL, and the diaper can be discarded without being soiled.

Also in this embodiment, the tape fastener 6
Since 0 is also used as a tape fastener for adjusting the tightening around the waist, material costs can be significantly reduced as compared with a case where tapes of both functions are separately provided.

<Fifth Embodiment> In a fifth embodiment, as shown in FIG. 22, the post-processing tape 70 conventionally provided on the outer surface of the diaper waist region is replaced with the diaper waist region which dares to touch the skin. The point is provided at the place provided on the inner surface of.

More specifically, as shown in FIG. 23, the base end of the post-treatment tape 70 is fixed to the inner surface of the diaper, in this case, the edge of the waist opening WO in the liquid-permeable top sheet 1 by an adhesive 73. , The tip side is the waist opening WO
It is preferable to adopt a two-fold structure that is folded back downward and is peelably adhered to a release tape 74 provided on the inner surface of the diaper. In this case, a locking portion 71 made of an engaging member such as an adhesive layer or a hook portion is provided on a surface of the folded portion facing the inner surface of the diaper.

The post-treatment tape 70 is folded back inside the diaper at the waist opening WO as shown in the figure, and is held in a state before use in a state where the whole is hidden below the waist opening edge inside the diaper. Is preferred. Thereby, the post-processing tape 7 can be used while the diaper is being worn.
0 is not noticeable, and the post-processing tape 7
There is an advantage that the possibility that 0 is extracted is small.

Further, as shown in FIG.
Is preferably attached along a longitudinal centerline passing through the center of the diaper in the width direction. By providing the post-processing tape at least at such a position, the diaper can be fastened in a well-balanced manner when the diaper is rolled and fastened.

Further, since the post-treatment tape 70 of this embodiment is in direct contact with the skin, it is preferable that at least the surface portion in contact with the skin, specifically, the entire tape base 72 be formed of a soft and breathable nonwoven fabric. . Further, when a peeling tape or a knob 75 that is not locked to the inner surface of the diaper is formed at the end of the folded portion, the peeling becomes easy and the post-processing tape 70 becomes easy to use.

When the diaper is discarded, as shown in FIG. 24, the body without the post-processing tape 70, that is, in this example, the front body F is moved from the crotch L to the waist opening WO.
After being wound up to the side, as shown in FIG. 25, the tape 70 with the folded portion peeled off from the inner surface of the diaper is stretched beyond the waist opening WO of the front body F, and is locked on the outer surface of the wound up portion, whereby the diaper is wound. It can be fixed in a rolled state, and the diaper can be discarded without becoming dirty.

As shown in FIG. 26 (A), if the post-processing tape 80 is provided on the outer surface of the diaper, for example, on the outer surface of the back body B, it is wound up by the thickness of the front and rear bodies F and B at the time of disposal. Since the tape is brought to the outer surface, the radius of curvature increases, and the tape length also increases. In particular, in this type of pants-type diaper, the part where the tape is turned usually shrinks due to the elastic member at the waist, etc.
It has a large effect on tape length. This is the conventional type. However, when the post-processing tape 70 is provided on the inner surface of the diaper as in the present embodiment, as shown in FIG. 26 (B), it is only necessary to pass the post-processing tape 70 outside one body F at the time of disposal. With a smaller radius of curvature, it can be brought to the fastening portion on the outer surface of the hoisting section by a shorter path. Therefore, the post-processing tape 70 can be shorter than in the conventional example, and the material cost can be reduced.
Moreover, in the case of this embodiment, the waist opening can be sufficiently closed.

Although not shown, it is preferable to attach the post-processing tape to both the inner surface of the front body and the inner surface of the back body, since it is not necessary to worry about the winding direction at the time of disposal.

[0070]

As described above, according to the present invention, it is possible to reliably perform the post-processing, and it is possible to reduce the cost.
