The present invention relates to a disposable diaper which provides convenience to the baby's activity by providing elastic means to the absorbent body of the diaper to impart the elasticity of the disposable diaper.

Korean Patent Publication No. KP 91-5218 (91.04.01) discloses a patent for forming two or more elastic means in an absorbent article, but does not specifically mention the elastic modulus of the elastic means. Although it is difficult to form wrinkles in the absorber, and when too much elasticity is formed in the absorber too much wrinkles, it has a considerable difficulty in maintaining the shape of the absorbent product. Therefore, the present invention improves the problems of the prior patents to provide a product that is more comfortable to wear.

The liquid permeable top sheet used in the disposable diaper in the present invention is a known one used in a disposable diaper, and a commonly used top sheet is a nonwoven fabric.

The absorbent material consists of a combination of tissue, a cellulose fluff fiber layer, a nonwoven fabric, and a super absorbent polymer. The superabsorbent polymer absorbs and stores body fluids, secretions and excreta. Silver wood is processed into fluff.

The liquid-impermeable backsheet is a well-known polyethylene film commonly used for disposable disposable diapers and is generally used for breathability and non-breathability, and a laminate of a nonwoven fabric is also used.

The main component of the present invention is used as a liquid permeable top sheet, absorbent and liquid impermeable back sheet used in a conventional disposable diaper, and other auxiliary components are known as the following (1) tissue (2) thigh, Elastic body for waist and leg (3) Coagulation band (4) Superabsorbent material (5) Hotmelt (6) In disposable diapers using fastening means, etc., the absorber is made thinner to reduce the volume of the diaper, and the elastic means It is an object of the present invention to provide a disposable diaper that fits well to the baby's body and thus does not inconvenience when active.

Therefore, in order to achieve the object of the present invention, the absorbent body of the diaper is made of a non-woven fabric and a superabsorbent polymer or tissue, if necessary, a thin absorbent sheet, and the elastic body is disposed so as to have an elastic modulus of 100-350% on both sides of the absorbent body.

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

1 shows a plan view of the present invention.

The liquid permeable top sheet 1 typically uses a nonwoven fabric, and may also be used by bonding a bulky nonwoven fabric to improve the feel. The side nonwoven fabric 2 is hydrophobic as a material for forming the solidified band 6, and a spunbonded nonwoven fabric is mainly used.

The liquid impervious back sheet 3 is mainly made of a polyethylene film, or a material in which a polyethylene film and a nonwoven fabric are laminated.

The absorbent body 4 mainly consists of a combination of cellulose fluffy fiber layer, tissue, nonwoven fabric, adhesive, and super absorbent polymer, and increases the amount of super absorbent polymer according to the required amount of absorbent urine. When wearing the diaper (D) to form an elastic body in the absorber so as to fit the baby body, which is called the absorber elastic body 19 is formed in part or the entirety in the longitudinal direction of the diaper, the elastic modulus of the absorber elastic body 19 is the absorber (4) The adjustment is preferred within the range of 120 to 330%, preferably 150-300%, and more preferably 200-250%, depending on the thickness and the strength. It is preferable that the absorber elastic body 19 can be disposed in the absorber 4 and above and below, and disposed in the left and right symmetry within 3 cm of both ends of the width of the absorber 4. As the absorbent elastomer 19, elastic yarn and natural rubber of a polymer polymer are mainly used. The shape of the absorber 4 is mainly a straight line.

Leg and waist elastic body 15 is mainly used as a means to form elasticity to prevent leakage and improve the fit, Lycra, natural rubber, and the molding method of leg and waist elastic body (5, 15) is divided into straight and curved, An elastic body also uses one or more strands, and the elastic body is fixed between the liquid-impermeable back sheet 3 and the nonwoven fabric by a hot melt adhesive.

The waist elastic body 15 maintains an elastic modulus of 100-250% of the diaper width or part of one or more elastic bodies to form elasticity at the ear portions of the waist portions 16 and 17 of the front and rear surfaces of the diaper D. (D) a liquid-impermeable back sheet (3), a liquid-permeable top sheet (1), and an absorber (1) containing 0.5 to 5.0 cm in the longitudinal direction on both sides of the front and rear absorbers (4). 4) is bonded between.

The coagulation band 6 is mainly formed by the side nonwoven fabric 2, and the liquid permeable upper sheet 1 may be formed by overlapping or separate materials. In order to form the coagulation band 6, the coagulation band fixing part 10 and the coagulation band end adhesive part 11 should be provided with a coagulation band elastic body 12. The fixing means for fixing the high-temperature melt adhesive and heat adhesion Method or ultrasonic bonding method.

The coagulation band 6 forms a pocket and serves to receive the excrement, thereby preventing leakage.

In order to effectively achieve this function, the material of the curd band 6 may be overlapped in two layers as a hydrophobic nonwoven fabric, or a film laminated nonwoven fabric may be used.

The fastening means protects the fastening force of the fastener and the fastening part 7 including the handpiece 14 to the fastening part 7 and the fastening part 8 and the fastening part 7 to enable refastening. It includes a fastening receiving portion (9) for receiving and fastening the diaper to the baby. The fastening portion 7 may be adhered to the outer surface of the liquid impermeable back sheet 3 in the back waist portion of the diaper or between the side nonwoven fabric 2 and the back sheet 3 before the diaper.

The fastening part guard 8 is attached to the outer surface of the side nonwoven fabric 2, and forms a Y-coupling 13 with the fastening part guard 8 to impart resistance when pulling the fastening part 7. The fastening portion 7 may consist of adhesive coated tape, hooks or buttoned tape fasteners each, or a combination of these fasteners may be used.

The fastening part accommodating part 9 is a part for accommodating the fasteners mentioned above to wear a disposable diaper on a baby's body, and is applied in different forms depending on the fastener type, and typically, an adhesive tape and a polyethylene film for fasteners are glossy or matte. Recently, the loop type fastening part accommodating part 9 is used as the hook type fastening part 7. The fastening part guard 8 may not be used depending on the shape of the fastening part 7.

2 is a partial cross-sectional view taken along the line A-A from the crotch portion 18 in FIG.

Hereinafter, the superiority of the present invention will be described with reference to Examples and Comparative Examples.
