[0002]

2. Description of the Related Art Conventionally, as a disposable diaper, for example, in a side flap of a flat type diaper as disclosed in Japanese Patent Application Laid-Open No. 57-77304, a portion corresponding to the left and right abdominal parts when worn is previously determined. A so-called pants-type diaper has been proposed in which an opening around the waist and an opening around the leg are provided while being joined and fixed. Further, in such a pants-type disposable diaper, stretch elasticity is imparted to the opening around both legs, the opening around the waist, and the both sides around the waist in order to enhance the followability and fit of the diaper to the wearer. Japanese Unexamined Patent Publication Nos. Hei 3-16920, Hei 4-28363, Hei 4-1661
No. 50 and JP-A-4-289201. Such a pants-type disposable diaper can be detached by a wearer, and its demand is increasing even when the diaper is separated from an infant or for adults such as incontinent persons.

[0003]

SUMMARY OF THE INVENTION
In a pants-type disposable diaper as described in JP-A-20 and JP-A-4-28363, a stretchable elastic member is provided at the opening around the waist and the opening around both legs. These elastic members provide the diaper with a function of narrowing the opening, fitting the absorber to the wearer, and preventing leakage from the opening.

As described above, as a method of arranging and fixing the elastic member along the opening in an extended state, as described in each of the above publications, a hot sheet is provided on at least one of the opposing surfaces of two sheets. A method of applying a melt adhesive and sandwiching a stretchable elastic member between two sheets is generally widely used.

In this method, in order to arrange and expand and fix the elastic member along the leg opening, it is necessary to provide a hot melt adhesive at least in a region of a predetermined width along the leg opening. It is required that the adhesive be fixed so that it does not peel off due to the contraction force of the elastic member in the stretched state. Increasing the amount of adhesive not only impairs the texture of the bonded sheets, but also allows the product to be used Undesirably leads to an increase in the manufacturing cost.

When the hot melt adhesive is applied by a contact type coater and solid-coated, the texture of the sheet is impaired, and when a gas-permeable material is used for the sheet, it is difficult to form a sheet. It is not preferable because it impairs air permeability.

[0007] In addition, as a coating shape of the hot melt adhesive, there is also known a method of applying using a non-contact type spiral spray coater or a curtain spray coater. Is adhered to the sheet in the form of a fine mesh or mist accompanying the heated air, and does not hinder the air permeability of the sheet unlike solid coating because there are fine gaps between the adhesives. However, in order to adhere and fix it so that it does not come off due to the contraction force of the stretchable elastic member in the stretched state, it is necessary to apply an appropriate amount of hot melt adhesive, and in this case, the adhesion of the sheet is different from solid coating. There was a problem that the texture was not good.

[0008] When a contact type coater is used, it is possible to apply a predetermined width to the vicinity of the position where the elastic members are arranged, but it is possible to bond the sheet between the parts where the elastic members are not arranged. Must be equipped with a further coater so as not to impair the texture.

An object of the present invention is to provide a pants-type disposable diaper formed of an absorbent body and an exterior member, forming the exterior member from a nonwoven laminate, and tightening an opening around a leg between the laminated nonwoven fabrics. The present invention is to provide a pants-type disposable diaper having a good texture and extremely excellent breathability by fixing the diaper with a hot melt adhesive.

[0010]

According to the present invention, there is provided an absorbent body having a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorber disposed between the two sheets.
At the time of wearing, surrounding the waist circumference and the leg circumference from the wearer's belly and joining the exterior member holding the absorbent body against the wearer and joining the opposite side edges of the front body and the rear body of the exterior member. A pants-type disposable diaper joined to form a waist opening and a pair of leg openings, wherein the exterior member laminates an inner layer and an outer layer made of a nonwoven sheet, and the leg between the two layers A stretchable elastic member is arranged in a stretched state in a region where a surrounding opening is formed, and at least including a region where the stretchable elastic member is arranged, is applied to one of the inner and outer layer sheets in a horizontal stripe shape. The present invention relates to a pants-type disposable diaper characterized in that the inner and outer layer sheets are bonded and fixed by an adhesive.

Further, the present invention provides that the horizontal stripe-shaped (stripe-shaped) adhesive layer is disposed in a continuous parallel line-shaped or band-shaped layer over both side edges of the exterior member over the entire area in the longitudinal direction. The present invention relates to the above-mentioned pants-type disposable diaper. The present invention also provides the pants-type disposable diaper, wherein the horizontal stripe-shaped adhesive layer is disposed in a longitudinal direction of both side edges excluding a central portion along a longitudinal direction of the exterior member. About.

The present invention is characterized in that the horizontal stripe-shaped adhesive layer is formed as a continuous parallel linear or band-shaped layer extending over both side edges of the exterior member, and has a constant width from both ends in the longitudinal direction of the exterior member to the center. Characterized in that the pants-type disposable diaper is disposed over the entire region in the longitudinal direction except for the band-shaped region. Further, in the present invention, the horizontal stripe-shaped adhesive layer is disposed at a portion having a constant width from both ends in the longitudinal direction of the exterior member to the center and a portion having a constant width from both sides to the center, The present invention relates to the pants-type disposable diaper, wherein the pants-type disposable diaper is not arranged in a central region of the exterior member.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The pants-type disposable diaper according to the present invention provides the absorbent body with a function of retaining the excrement required for the disposable diaper inside and outside the absorber, and the exterior member includes the absorbent body. The body has a function of keeping the absorbent body in close contact with the body of the wearer, and also has the function of suppressing the displacement of the absorbent body with respect to the movement of the wearer. Stretch, elasticity is given to the opening around the waist, and the side around the waist, giving a good feeling of wearing. Further, the outer layer sheet and the inner layer sheet forming the exterior member are made of a nonwoven fabric sheet. Has excellent breathability,
Without sweat staying inside the diaper while wearing it,
An extremely good wearing feeling similar to the feeling of wearing underwear is obtained.

In the pants-type disposable diaper according to the present invention, as means for imparting elasticity to the opening around the leg,
The stretchable elastic member is disposed in an extended state between the outer layer sheet and the inner layer sheet of the exterior member, and in order to integrate them, one of the facing surfaces of the outer layer sheet or the inner layer sheet is coated with an adhesive. Is adopted. At that time, the outer layer sheet and the inner layer sheet, and the stretchable elastic member sandwiched therebetween are integrated in an extended state, and in order to prevent the elastic member from peeling off from the outer layer sheet or the inner layer sheet, the elastic sheet and the stretchable elastic member must be combined. It is preferable to select a hot melt adhesive having a high adhesive strength. For the above purpose, it is also an effective means to increase the amount of the adhesive used to some extent, but in this case, the wearing feeling close to the underwear by using a nonwoven sheet up to the inner layer sheet in addition to the outer layer sheet and a good feeling are obtained. It is necessary to use the exterior member within a range that does not impair the characteristics of the exterior member whose air permeability is to be ensured.

In the case of the pants-type disposable diaper of the present invention,
In order to obtain a good wearing feeling, it is effective to arrange the elastic elastic member in a curved manner between the outer sheet and the inner sheet along the opening around the leg. In order not to impair the feel of the whole exterior member when the elastic member is bent and bonded and fixed, horizontal stripes are formed in a region of a predetermined width along an opening around the leg between the outer layer sheet and the inner layer sheet ( It is necessary to sufficiently coat the hot melt adhesive in the form of parallel stripes) to integrate the outer layer sheet, the inner layer sheet, and the elastic member. However, for a portion where it is not necessary to fix the stretchable elastic member in the stretched state simply by bonding the outer layer sheet and the inner layer sheet, increasing the amount of the adhesive not only impairs the texture of the bonded sheets, However, this is not preferable because it leads to an increase in the manufacturing cost of the product.

The coating shape of the hot melt adhesive is as follows.
When coating with a contact type coater, do not apply solid coating,
It is necessary to provide a coating area having alternately linear or band-shaped coating portions and non-coating portions by coating in a horizontal stripe shape, and to hold the stretchable elastic member in an extended state as the entire coating region. If the amount of adhesive per unit area is applied, it is possible to obtain the same holding force of the elastic elastic member as when the same amount of adhesive per unit area is solid applied. Thus, it is possible to obtain an exterior member which maintains a good texture and has an excellent wearing feeling without impairing the air permeability of the nonwoven fabric sheet.

In the case of the pants-type disposable diaper of the present invention,
It suffices to apply a hot melt adhesive to either the outer layer sheet or the inner layer sheet made of the nonwoven sheet forming the exterior member. The hot melt adhesive is applied in the form of horizontal stripes (parallel stripes), and in the region where the elastic member exists, the outer layer sheet, the elastic member, and the inner layer sheet are integrated with the elastic member therebetween, and the elastic member is In the non-existing region, the outer layer sheet and the inner layer sheet are integrated, and in any region, the outer layer sheet and the inner layer sheet are integrated with an adhesive non-existing portion, thereby providing an exterior member in which air permeability is ensured. .

In the case of the armor member used for the pants-type disposable diaper according to the present invention, the elastic members around the legs are usually arranged in a curved shape. Since each of the linear or band-shaped adhesive portions intersects at a certain angle with the elastic members around the legs, the elastic members around the legs are arranged on the non-coated portion of the adhesive. Is small and can be securely bonded and fixed.

The elastic member around the leg is disposed along the opening around the leg, and has a function of fixing the diaper to the wearer by tightening the opening. There are various possible arrangement methods and shapes of the members in the vicinity of the opening around the leg, and depending on the arrangement shape of the elastic members, the adhesive coated portion (line) and the elastic members may be formed in a very small portion. It is also conceivable that a part of the elastic member that is parallel and has a portion that is not fixed to the inner and outer layer sheets over a relatively long part. However, such a state does not occur at least at a portion along the opening around the leg, and thus does not cause a serious problem. If necessary, solid coating or coating with a non-contact type coater can be separately performed only on the part where both become parallel, but it is possible from the viewpoint of maintaining the texture and air permeability of the exterior member It is preferable to respond only by performing stripe-shaped coating as much as possible.

In the case of the pants-type disposable diaper of the present invention,
A hot-melt adhesive is applied in a horizontal stripe shape to one of the outer layer sheet and the inner layer sheet forming the exterior member, thereby forming a coated portion and an uncoated portion of the adhesive. Even if the stretchable elastic member around the leg is stretched and fixed to the inner and outer layer sheets by the coated portion, the outer layer sheet and the inner layer sheet are not bonded and fixed in the non-coated portion. When shrinks, the outer layer sheet and the inner layer sheet portion which are not fixed to each other shrink while maintaining the original softness and air permeability of the nonwoven fabric, so that the feel and air permeability are maintained.

Depending on the method of forming the exterior member and the arrangement and shape of the elastic members around the legs, the linear or band-shaped adhesive layer arranged in a horizontal stripe is not a continuous layer but a discontinuous linear layer or band. It can also be formed as a layer. In particular, the non-contact type coater is used to coat the hot melt adhesive in the center region of the armoring member, which is located away from the region where the elastic elastic member is located at the opening around the leg in the armoring member. Can be applied to a minimum amount necessary for bonding the outer layer sheet and the inner layer sheet.

In the case of a pants-type disposable diaper, it is necessary to dispose an elastic member at the opening around the waist, but it is effective to arrange the elastic member around the waist in a straight line. Therefore, with respect to the fixing of the elastic member with the hot melt adhesive, here, the coated portion and the non-coated portion are alternately arranged in a stripe shape perpendicular to the elastic member along the direction of the arrangement of the elastic member. The stretchable elastic member can be sandwiched and fixed between the outer layer sheet and the inner layer sheet by using a coating method provided on the outer layer sheet and a coating method using a non-contact type spiral spray coater or curtain spray coater.

The absorbent main body of the pants-type disposable diaper according to the present invention comprises a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber. As the liquid-permeable top sheet, a liquid-permeable nonwoven fabric made of synthetic fibers made of polyethylene, polypropylene, polyester, or other thermoplastic resin is preferably used.

The absorbent can be used as long as it is generally used for absorbent articles such as diapers for babies and incontinent persons. However, cotton-like pulp and a super absorbent polymer which is a super absorbent material are used. It is preferable that they are mixed and further wrapped by a hydrophilic sheet. Further, a cotton-like pulp may be mixed with a heat-fusible substance in an amount of 3 to 60% by weight and thermocompression-bonded. The structure of the absorber is not particularly limited. For example, a single layer mainly composed of cotton-like pulp may be used, or a highly absorbent polymer (SA) may be added to cotton-like pulp.
It may be a layered material containing a highly absorbent material such as P). Further, a structure in which a uniform layer made of a highly water-absorbing material is sandwiched between two single layers mainly composed of cotton-like pulp may be used.

The amount of the SAP is 10 to 500%, preferably 15 to 300% of the total weight of the floc pulp in a dry state.
An absorbent is preferred in which such an amount of SAP is substantially uniformly distributed in the fluffy pulp. In such an absorber, when the SAP absorbs and swells, the particles have minimal interference with each other, are less likely to form a permeation barrier by continuous contact, and transport urine and body fluid in a three-dimensional direction. Transmit and absorb. A hydrophilic sheet disposed above, below, or entirely over the absorber can be used. The hydrophilic sheet is
Any sheet that is hydrophilic may be used, for example, tissue,
Absorbent paper, hydrophilic non-woven fabric and the like can be mentioned.

Examples of the liquid-impermeable back sheet include a liquid-impermeable polyethylene sheet, preferably a polyethylene sheet having micropores, and a moisture-permeable liquid-impermeable sheet obtained by adding a filler to a thermoplastic resin and stretching. Alternatively, a liquid-impermeable sheet and a nonwoven fabric may be attached to each other, and a material provided with moisture permeability in this way is more comfortable without humidification.

The shape of the absorbent main body may be an hourglass type, a rectangular type, a T-shaped type, etc., but is not particularly limited, and may be any suitable shape that is neither too wide nor too narrow in the crotch region.

The outer member of the pants-type disposable diaper of the present invention is formed by laminating and bonding an outer layer sheet made of nonwoven fabric and an inner layer sheet made of nonwoven fabric with a stretchable elastic member interposed therebetween. As the outer layer sheet and the inner layer sheet, a non-woven fabric made of synthetic fibers made of polyethylene, polypropylene, polyester, or other thermoplastic resin can be used.

The leg-opening elastic member and the waist-opening elastic member sandwiched between the outer layer sheet and the inner layer sheet are made of elastic material such as urethane thread, thread rubber, etc., which is used for ordinary diapers. The elastic body can be used as it is, and these elastic members are adhered and fixed to predetermined regions by a horizontal stripe-shaped (stripe-shaped) adhesive at the leg opening and the waist opening in the extended state, respectively.

As the adhesive, a hot melt adhesive is advantageously used. In addition, a water-soluble glue such as starch or CMC (carboxymethylcellulose) or an adhesive having a high fluidity can also be used. . As the hot melt adhesive, a styrene-butadiene-styrene copolymer or a styrene-isoprene-styrene copolymer, which is a synthetic rubber-based hot melt adhesive, can be used.

The width of the coated portion of the adhesive layer in the form of a horizontal stripe is 1 to 3
mm, and the width of the non-coated portion between the coated portions is preferably about 1 to 2 mm. It is not preferable to make the width of the coated portion smaller than 1 mm because stable coating becomes difficult, and conversely, to make the width larger than 3 mm is similar to a solid coating, so that the texture of the exterior member is reduced. Connection is not good. In addition, the width of the uncoated part is 1
It is not preferable that the width is smaller than 2 mm because it is substantially the same as that of the solid coating. On the contrary, it is not preferable that the width is larger than 2 mm because it becomes difficult to hold the stretchable elastic member in the stretched state.
