Description

Disposable diaper comprising enforced back waistband panel with reinforced back waistband

The present invention is a high-absorption of the elastic panel consisting of a backsheet non-woven fabric and elastic yarn-spandex or natural rubber-spandex to the first waist region in order to improve the adhesion and fit of the waist after the wearer in the disposable absorbent product A disposable absorbent product having a function. More specifically, the present invention is to place the elastic panel located from the first waist region to the back waist portion of the disposable absorbent product to increase the adhesion of the back waist band portion when worn to reduce the fit and sagging of the absorbent product. In addition, the present invention relates to a disposable absorbent product having improved parallelism with the fastening system to further improve the fit.

Generally, disposable absorbent products are products that absorb body fluids excreted by physiological actions, that is, products that absorb urine and feces. More specifically, diapers used by infants, diapers used by incontinence ( adult diaper and sanitary napkin.

Common disposable absorbent products are products that absorb body fluids excreted by various physiological actions, that is, products that absorb urine, feces, menstrual discharge and vaginal discharge. More specifically, disposable diapers used by infants or incontinence (disposable diaper), sanitary napkins, panty liners, and the like.

The present invention is particularly preferably applied to disposable diapers in disposable absorbent articles.

Disposable diapers consist of a liquid-permeable top sheet that is in direct contact with the wearer's skin when worn, a liquid-impermeable back sheet that forms an outer surface when worn, a liquid-permeable top sheet, and Absorbent core located between the liquid-impermeable back sheet, and a coagulation band formed around the absorbent to improve the fit of the wearer's thigh, to prevent the excretion from leaking out, and to improve the appearance image. barrier cuff) and fastening means. In addition, if necessary, a leg elastic body (leg elastic) to prevent side leakage and a waist band (waist band) for improving the wearing feeling of the waist may be included.

Among the components of these disposable diapers, a liquid permeable top sheet is a synthetic backsheet nonwoven fabric or a film having a hole formed therein so that body fluid can quickly pass through the absorbent body. Synthetic backsheet nonwoven fabrics are usually used by hydrophilic treatment of hydrophobic fibers in order to quickly transfer the body fluid to the absorbent body.

The liquid impervious back sheet prevents body fluids absorbed by disposable diapers from leaking under the absorbent to contaminate the wearer's clothing or the surrounding environment.It is made of a waterproof film and a back sheet nonwoven fabric. The film mainly uses a polyethylene film, and the back sheet nonwoven fabric is attached to the polyethylene film to further improve the soft touch in the feel of the material. In addition, the liquid-impermeable back sheet may be applied only to a portion to which the absorbent of the disposable absorbent product is applied without attaching the waterproof film to the entire back sheet to impart breathability. Therefore, the entire backsheet including the portion without the absorber may be bonded to the backsheet nonwoven fabric so that only the backsheet nonwoven fabric exists on the edge portion of the non-waterproof film so that the ventilation is good.

In addition, the absorber is typically made of fluff pulp, super absorbent polymer (tissue) and the tissue (tissue) for packaging it, and absorbs the body fluid passing through the liquid permeable top sheet at high speed, Once absorbed, the body fluid absorbs and retains the body fluid to prevent contact with the skin again.

In addition, the fastening means consisting of a fastening means and a frontal fastening means (frontal tape, landing member) is further included so as to maintain the disposable diaper configured as described above on the body.

These materials are bonded and fixed by hot melt adhesive bonding, heat fusion or other commercially available bonding methods.

The technique of the disposable absorbent product as described above can be adjusted so that there is no inconvenience for the wearer in terms of the basic performance in terms of the speed and absorption power to absorb the body fluid discharged by the physiological action.

The development of disposable absorbent products is progressing in the direction of improving the fit to meet basic performance, and as one method for this, an ultra-thin disposable absorbent product has been developed that makes the absorber thinner. One simple method for producing the ultra-thin disposable absorbent product is to reduce the amount of cotton pulp that takes up a lot of volume, and to manufacture the absorbent using a large amount of super absorbent polymer (SAP).

If the ratio of the mixed content of the down pulp and superabsorbent resin in the ultra-thin disposable absorbent product as described above is not appropriate, wear the absorbent product for a long time, or if the wearer's activity or movement is severe, the initial wearing state The lower the sag, the absorber is reduced in width, the absorbent is deformed to cause a phenomenon of clustering or splitting. Therefore, the absorber thus deformed has a poor absorption function, which lowers usability and increases the possibility of leakage.

In addition, the absorbent deformed during use decreases the absorbed area, especially when the wearer's movement is severe and the absorbent product is not in close contact with the wearer's body. The permeable topsheet is hydrophilic, but the hydrophilic surface becomes hydrophobic due to repeated urination and the like and delays delivery to the absorber during urination, thereby increasing the likelihood of leakage in the deformed absorber. In other words, depending on the wearer's movement and position, the droppings are often leaked out of the absorbent product before they are absorbed. This is a problem that occurs when the absorbent product is not fastened to the wearer's body, or when the absorbency of the absorbent product is insufficient due to poor wearability during use. This wearability problem occurs especially when the waist is not in close contact with the wearer's body. The elasticity of the waist is the most important point because the wearer, especially the baby's body, is not fastened with the absorbent product initially worn.

In order to reinforce the elasticity of the waist portion, a material having excellent elasticity, that is, polyurethane (polyurethane), polyethylene (polyethylene), etc. are mainly used, and the form varies from film to foam.

However, in the case of a conventional absorbent product, its function is not sufficient enough to cause sagging when the disposable absorbent product is worn for a long time, and is not in a state of satisfactory in leakage prevention effect.

SUMMARY OF THE INVENTION An object of the present invention is to provide a disposable absorbent article having excellent fit and leakage preventing effect by including a reinforced back waistband in a disposable absorbent article.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, the disposable absorbent article comprising the reinforced back waistband according to the present invention is a liquid permeable top sheet 7, a liquid impermeable back sheet, the top sheet ( 7) and the body portion including the absorbent body (1) positioned between the back sheet and the thigh portion of the wearer to improve the fit, and includes a clogging band (4) to prevent leakage of excretion, the body portion of the first waist area The first fixing member 13 is divided into a second waist region 20 and a leg band 17 in the longitudinal direction of the body portion, and is worn on the first waist region 21. And a second fixing member (15) coupled to the first fixing member (13) in the second waist region (20), and a panel elastic body as a waist band in the first waist region (21). 10) in the direction parallel to the terminal edge 19 along the terminal edge 19 of the absorbent article. It characterized by after a yirueojim to form the elastic waistband panel 16.

Referring to the top view of Figure 1 as follows.

Disposable absorbent product according to the present invention is an hourglass divided into a second waist region 20 having the second fixing member 15 and a first waist region 21 having the crotch portion and the first fixing member 13 installed therein. It has a form of appearance. The appearance of the disposable absorbent article does not necessarily have to be symmetrical structure in front and rear and right and left, but preferably has a left and right symmetrical structure. In particular, FIG. 1 shows a state in which the back waistband elastic panel 16 made of the panel elastic body 10 is formed in the first waist region 21.

FIG. 2 is a cross-sectional view taken along the line II ′ of the crotch portion of FIG. 1.

As specifically shown in Figure 2, the absorbent body (1) has a structure in which the tissue (9) is wrapped around the down pulp (5) and superabsorbent polymer (6), the absorber (1) is the top sheet (7) And the back sheet nonwoven fabric 2 constituting the back sheet. In addition, the solidification band 4 is elastic by the solidification band elastic body (8).

Figure 3 is a perspective view from the rear of the state before the wearer wearing a disposable absorbent product according to the present invention, in particular, the back waistband elastic panel 16 is composed of a panel elastic body 10 in the rear waist Indicates.

FIG. 4 is a cross-sectional view taken along the line II-II 'of FIG. 1, and particularly shows a position at which the back waistband elastic panel 16, which is composed of the panel elastic body 10, is mounted on the back waist portion.

FIG. 5 is a view illustrating the rear waistband elastic panel 16 separately.

In the back waistband elastic panel 16 of FIG. 5, the panel elastic body 10 and the elastic body fixing member 11 are integrally coupled to each other, and the panel elastic body 10 is fixed in the elastic body fixing member 11 in a state where the panel elastic body 10 is sufficiently stretched. In such a way, the entire elastic fixing member 11 may be stretched further by external force. This will allow the back waist band elastic panel 16 to be sufficiently stretched to have elastic force and to be worn closely on the wearer's body in the future use of the product.

7 is a plan view schematically showing another specific embodiment of the disposable absorbent article including the reinforced back waistband, and FIG. 8 schematically shows the manufacturing process of the back waistband in the disposable absorbent article of FIG. It is a process chart.

In the present invention, a hot-melt adhesive is generally used by inserting the absorbent member 1 between the liquid impermeable back sheet composed of the back sheet nonwoven fabric 2 and the waterproof film 3 and the liquid permeable upper sheet 7. And a solidification band 4 is formed on the left and right sides outside the absorber 1 as leakage preventing means to form a pocket that primarily confines the body fluid which is separated from the absorber 1.

In addition, it is configured to enable the formation of a secondary pocket by the leg band 17 in addition to the solidification band (4).

The fastening means in the disposable absorbent article according to the present invention forms a second fixing member 15 (also referred to as a 'landing member') in the front portion of the absorbent article, that is, the second waist region 20, and also the first waist region. The first fixing member 13 is formed at 21 so that the absorbent article is firmly fixed at the side of the wearer's body. The first fixing member 13 may have a structure that is supported by itself, and generally may have a structure that is supported by the tape tab 12.

The material used for the tape tab 12 must have a holding force of the tape tab 12 itself over a predetermined value, and a back sheet nonwoven fabric composed of a polymer film or a polymer fiber. A material laminated with polypropylene or polyethylene on the surface of the material is used. When the tape tab 12 is made of a polymer resin film only, the flexibility (softness) is reduced in use, but it simplifies the manufacturing process of the disposable absorbent product including the tape tab 12 and reduces the material cost. You can expect.

The first fixing member 13 may be largely bonded in two forms. The first adhesion method is an adhesive coating method. The pressure-sensitive adhesive method by the pressure-sensitive adhesive coating may be coated with a hot melt type pressure-sensitive adhesive on the polymer film or a pressure-sensitive adhesive in the form of a solvent. The second method of bonding may consist of a mechanical closure system, ie a hook or the like. Therefore, when the first fixing member 13 is configured in the form of a polymer film made of an adhesive coating, the second fixing member 15 should be in the form of a vinyl film made of a polymer film such as polypropylene. In addition, when the first fixing member 13 is a hook type fixing member 22, the second fixing member 15 should be a loop fixing member 23 woven or molded from polymer fibers. 1 shows that a fastening system made of an adhesive method is applied, and FIG. 7 shows that a fastening system made of a mechanical fastening system such as a hook type fastening member 22 and a loop type fastening member 23 is applied. A finger tab 14 may be further attached to the first fixing member 13 to facilitate gripping of the first fixing member 13.

Thus, the disposable absorbent article comprising the reinforced back waistband according to the present invention is fixed to the panel elastic body 10 on the fixing member of the first waist region 21 of the absorbent article, and then absorbed during the manufacturing process of the disposable absorbent article. It is applied near the terminal edge 19 of the product so that the back waistband elastic panel 16 is more elastic. In general, the panel elastic body 10 constituting the waistband is mainly composed of a polyurethane foam, a polyurethane film, a polyethylene film, and the like. Preferably, in the present invention, a polyurethane elastomer or an elastic yarn is used, and the elastic yarn is polyurethane. Spandex or natural rubber is used. The elastic yarn is bonded to the elastic fixing member 11 made of a back sheet nonwoven fabric of a certain basis weight or more by a high temperature melt adhesive or the like, and is formed on the panel elastic body 10 while having an elastic modulus of 130 to 250% while bonding to provide excellent elasticity. Panel elastic body 10 is to be made. That is, while the panel elastic body 10 is stretched in the range of 130 to 250%, the panel elastic body 11 is bonded to the elastic body fixing member 11, and the elastic body fixing member 11 is applied to the panel elastic body 11 between the elastic body fixing members 11. 10) is fixed in a tensioned state to have elasticity, which is schematically illustrated in FIG. 5.

The length of the back waistband elastic panel 16 composed of the panel elastic body 10 may be applied in the range of 10 to 100mm. When the length of the back waistband elastic panel 16 is formed to be less than 10 mm, there may be a problem that the function as a waist band is not performed, on the contrary, when the length of the absorbent body 1 exceeds 100 mm, The direction length becomes so short that there may be a problem with the absorbency, the most basic performance of a disposable absorbent product. The back waistband elastic panel 16 may have a width of 150 to 270 mm, and if the width is too narrow, the role of the waist band may be insufficient.

The back waistband elastic panel 16 can be directly applied in a disposable absorbent product production line, and is manufactured separately to increase process stability before attaching the liquid permeable top sheet 7 during the absorbent product manufacturing process. Can be. A method of directly applying in the manufacturing process of the absorbent article is schematically illustrated in FIG. 8, which shows one specific example of manufacturing the disposable absorbent article according to the present invention, and the present invention is not limited thereto.

8 shows the panel elastic body 10 fixed to a sub-porous fabric, which is an elastic body fixing member 11, in a step before attaching the back waistband elastic panel 16 to a disposable absorbent article, and then folding ( The method of folding is shown. In this case, in addition to the folding method, the method of adhering the elastic body fixing member 11 on and under the panel elastic body 10 may be applied. In this way, after the back waistband elastic panel 16 is manufactured, it is attached to the waistband position of the first waist region 21 before the liquid permeable top sheet 7 is attached. This waistband region is the upper portion (normally, the terminal edge 19 of the first waist region 21) just above the absorbent body 1, and the direction of the panel elastic body 10 is generally perpendicular to the longitudinal centerline of the absorbent article. To be arranged. The panel elastic body 10 is formed so that the elastic chamber is arranged in about 3 to 15 lines in order to give elastic force to the back waistband elastic panel 16. 8 illustrates a panel elastic body 10 in a state in which four rows of elastic yarns are applied.

Conventional waistbands are formed in which the waist elastic body is formed over the entire product width in the transverse direction between the longitudinal end end of the disposable absorbent article and the outside of the absorbent article 1, or partially short. And attached in the transverse direction (perpendicular to the longitudinal centerline) such that its end does not reach towards the longitudinal edge of the absorbent article at the central portion of the disposable absorbent article.

The back waistband elastic panel 16 is preferably attached such that the absorber 1 is positioned within 3 to 30 mm from below, for example, to prevent leakage and to wear.

In addition, in the disposable absorbent product according to the present invention, the waterproof film 3 and the back sheet nonwoven fabric are adhered to the liquid impervious back sheet as a whole so that the back waistband elastic panel 16 is disposed between the back sheet and the top sheet 7. It can be made to be located in. In this case, since the waterproof sheet 3 and the back sheet nonwoven fabric are completely covered on the back sheet, it is possible to completely block the generation of leakage through the back sheet. In addition, the waterproof film 3 of the liquid-impermeable back sheet is coated only on the absorbent body 1 portion, and the entire area except the absorbent body portion 1 may be made of only the back sheet nonwoven fabric, whereby the back sheet nonwoven fabric is composed of only the back sheet nonwoven fabric. The ventilation can be well ventilated to prevent moisture from getting on the wearing area.
