The present invention relates to a blocking cuff of a disposable diaper to prevent body excretion leaking into the crotch portion of the disposable diaper, the curved cuff is excreted along the crotch portion of the diaper so as to maintain a close contact around the thigh of the wearer A disposable diaper having a curved cutoff cuff characterized in that it has a cutoff cuff.

Full closeness used in the present invention refers to a state in which a cutoff cuff is wrapped in a circle without an open portion around the thigh of the wearer when the diaper is worn, and a curved shape is not disposed in a straight line like a known cutoff cuff. It refers to a state in which both ends of the blocking cuff are bent along the crotch portion of.

Known disposable cuffs are formed on both sides of the absorbent layer centerline and inside the elastic leg opening to form pockets or areas for receiving body excretion, overlapping fluid permeable or fluid impermeable skin, or breathable or waterproof materials. A separate cuff may be formed using a separate member, and the formed cuff may be formed by attaching a bridge having a fluid permeable inner shell and a fluid permeable outer shell onto the wrap.

The components of the known blocking cuff are fixed to each end of the blocking cuff on the absorbent body at the waist of the diaper in front of and behind the diaper to form the excretion receiving area, and the blocking cuff composed of separate members is adhered between both sides of the absorbent layer centerline and the inside of the elastic leg opening. It consists of an adhesive part, a blocking part that receives body excretion and leakage from the adhesive part, and a wrinkle part that overlaps the tip of the blocking part inward and forms an elastic band to excrete the elastic band. It is in close contact with the thigh of the wearer while preventing leakage into the opening.

For example, such a known diaper, in Korean Patent Application No. 87-3737, extends out of the absorber to form a gasketting leg cuff between the fluid permeable and fluid impermeable sheaths constituting the leg flap. An elastic member is disposed between the flap inner skin and the outer shell, and a separate member different from the inner skin and the outer shell is attached between the inner elastic band of the leg flap and the absorbent body to form a blocking cuff. In addition, in Korean Patent Application No. 88-4762, the separate cuff flap of a separate member forms a fluid impermeable outer shell and a gasketing leg cuff, and the fluid permeable endothelial extends out of the absorbent body, but the inner elasticity of the gasketing leg cuff. It shows the state terminated at the point where it is attached to the outer surface of the blocking cuff to start the blocking cuff inside the band.

Due to the difficulty and complexity of the known cutoff cuff, the cutoff cuff does not form a curved cutoff along the leg opening, and is formed in a straight shape in which both ends of the cutoff cuff are bonded to both waist absorbers over the entire length of the diaper. ought. The straight blocking cuff does not form a complete seal on the thigh of the wearer's leg when the wearer wears a diaper. That is, the upper part of the thigh is open while the wearer's thigh is not completely wrapped. Therefore, if the wearer's movement is unusually active, or the amount of excreta is too large, or the disposable diaper is used several times, the capacity of the excreta is reduced, or the wearing state is poor, and fluid body fluids that cannot be absorbed by the absorber may leak. There are often cases.

Accordingly, an object of the present invention is to compensate for these disadvantages to form a blocking cuff in a curved shape along the leg openings of the disposable diaper, thereby keeping the contact of the wearer's leg thighs completely to block leakage.

The means for achieving the object of the present invention comprises a curved blocking cuff made of a separate non-woven fabric on the bonding layer of the inner and outer shells extending out of the absorbent layer to form a leg flap, the curved blocking cuff is a separate member absorbent layer Preferably a 3-6 cm high barrier and a distal end of the barrier, which are erected from the curved bond and the bond, which are adhered along the curved leg opening from the outside onto the laminate layer from the inside, to block leakage of body excrement. It can be formed by the pleats forming the wrinkles or by forming a fold of both blocking portions of the blocking cuff to the quarter point from both ends to form a fold that serves to block the excretion leaking from the upper part of the wearer's thigh. have.

In the present invention, the liquid permeable endothelial is of a known material used in ordinary disposable absorbent products, and the most commonly used liquid permeable endothelial is nonwoven. Cellulose Fluff fiber layer used as an absorbent layer is made of Fluff by processing wood pulp, which is a hydrophilic absorbent material that absorbs secretions, and is a known material used in ordinary disposable absorbent products. In addition, the fluid impermeable outer sheath is a well-known material used in a general disposable absorbent product, and a common use is a non-breathable waterproof film, a breathable waterproof film, and a biodegradable waterproof film. Laminate can also be used.

Hereinafter, described in detail based on the accompanying drawings shown as an embodiment as follows.

The absorbent layer (3) is inserted between the fluid permeable endothelial (2) and the fluid impermeable outer shell (1), and has a fastening means (5) and a waist band (6) made of a magic tape or the like. In the known disposable diaper D having a waist 12, the curved blocking cuff E is placed on the laminated leg flap 13 of the inner skin 2 and the outer skin 1 extending from the absorbent layer 3. A separate nonwoven fabric is used to form an adhesive portion 7 which is curved along the crotch portion 11 on both sides of the diaper, and the adhesive portion 7 has one end portion of the width of the blocking cuff E and a laminate layer leg flap ( 13) is bonded with a margin to overlap with, and the junction portion 7 is composed of a straight portion 14 and a curved portion 15 or the entire curved portion 15, and by the adhesive components such as hot melt adhesive, glue The adhesive part 17 is formed. On the other side of the blocking cuff (E), the elastic chamber 16 is disposed, and the blocking cuff (E) stands up from the bonding portion 7 by the elastic force, and a breathable waterproof film, a decomposable waterproof film, or a nonwoven fabric can be used. Wrinkles are formed by the blocking portion 8 and the elastic chamber 16 to block leakage from the crotch portion 11, and consists of a pleated portion 9 which is in close contact with the wearer's thigh. When the height of the blocking cuff (E) is from 3 to 6cm or more from the adhesive portion 7 to the pleated portion (9), the height of the blocking cuff (E) is short and long, so that folding occurs, thus preventing air permeability and effectively blocking the excretion. More preferably, the height of the blocking cuff E is 4 to 5 cm. The elastic yarn forming the wrinkles 9 may be used as Lycra XA, natural rubber, latex, or the like, and an elastic yarn 16 having an appropriate elastic force is selected and used according to the wearer's body. In general, the elastic modulus of the elastic chamber 16 has 250 to 300%. One or more elastic chambers 16 may be used in the pleats 9 to form elastic wrinkles suitable for the body contact surface. Body contact surface of the wrinkles (9) can be maintained in close contact around the thigh of the wearer in a variety of shapes, such as T-shaped, |
