DETAILED DESCRIPTION

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same elements of the drawings are denoted by the same reference symbols whenever possible. Further, the detailed description of publicly-known function and configuration that may make the gist of the present invention unnecessarily ambiguous will be omitted.

[0022] FIGS. 1 to 3 are diagrams illustrating a disposable diaper according to an embodiment of the present invention. As illustrated in FIG. 1, when the disposable diaper 100 is divided by body parts, the disposable diaper 100 may be divided into a front surface part A touching an abdomen of a wearer 1, a rear surface part B touching a back of the wearer 1, and a gap part C in which the front surface part A and the rear surface part B extend in the lengthwise direction so as to pass through a space between legs of the wearer 1 and in the present invention, in order to specifically describe a feature, the disposal diaper 100 is divided into layers.

[0023] The disposable diaper 100 according to the embodiment of the present invention includes a base layer 110, a cover layer 120, and a skin contact layer 130 as illustrated in FIG. 2 and the base layer 110, the cover layer 120, and the skin contact layer 130 are integrally formed as illustrated in FIG. 3.

[0024] An external surface of the base layer 110 is made of a waterproof material so that the base layer 110 prevents urine and feces 10 generated by the wearer 1 from flowing out to the outside. An elastic part 114 is formed in the rear surface part B so as to flexibly surround the waist of the wearer 1 and bonding parts 113 attached to the surface of the waterproof material of the front surface part A are formed on both left and right ends of the rear surface part B.

[0025] This is a method that generally wears the disposable diaper 100 and a detailed description thereof will be omitted and in addition to this method, the front surface part A and the rear surface part B are extended and coupled so as to surround the waist of the wearer 1 to be formed in a panty shape.

[0026] This is also a method that generally forms the disposal diaper and the detailed description thereof will be omitted.

[0027] Further, in the base layer 110, an absorber 111 is provided on an inner surface in the lengthwise direction based on the center of the gap part C and first elastic members 112 are stretchably provided at both sides of the lengthwise direction so as to surround the legs of the wearer 1. In this case, it is preferable that a plurality of first elastic members 112 may be provided according to a degree of elasticity.

[0028] Herein, in the description of the base layer 110, the inner surface or the upper end refers to the inside which is the skin side when worn by the wearer 1, and the outer surface or the lower end refers to the outside which does not contact the skin of the wearer 1.

[0029] Herein, the absorber 111 is seated and fixed on the inner surface of the base layer 110 and the absorber 111 extends in either direction of the front surface part A or the rear surface part B or in both directions to increase absorption force of the urine.

[0030] The cover layer 120 is located on the upper end of the absorber 111 and covers the absorber 111 to prevent the absorber 111 from being released to the outside and the urine of the wearer 1 is easily absorbed in the absorber and the cover layer 120 is preferably made of a material that prevents the absorber 111 from being released to the outside.

[0031] The skin contact layer 130 is located on the upper end of the base layer 110 where the cover layer 120 is located and the inlet cutting part 131 which is cut with a predetermined length is formed so that the urine and feces 10 may easily reach the cover layer 120 or the absorber 111, and second elastic members 132 which come in close contact with a lower skin of the buttocks of the wearer 1 is formed in the lengthwise direction of both sides of the inlet cutting part 131.

[0032] In this case, the second elastic member 132 is formed on the skin contact layer 130 in the lengthwise direction and preferably formed in parallel to the skin contact layer 130.

[0033] Further, the inlet cutting part 131 may be separated into a urine inlet cutting part 131a in which the urine is absorbed and a feces inlet cutting part 131b in which the feces 10 is received. A shape of the urine inlet cutting part 131a may be diversified as described in the embodiment illustrated in FIGS. 4(a) to 4(d), but the feces inlet cutting part 131b is preferably formed in a wearing lengthwise direction. As the feces inlet cutting part 131b is formed in the wearing lengthwise direction, the feces is received through the feces inlet cutting part 131b, but when the feces inlet cutting part 131b is circular, the wearer 1 needs to wear the disposal diaper by matching the anus with the circular feces inlet cutting part 131b, and as a result, to match the anus and the feces inlet cutting part 131b, this may be difficult.

[0034] Even if the feces inlet cutting part 131b is not formed in an artificially opened form by the formed second elastic member 132, as the second elastic member 132 comes in close contact with the buttocks of the wearer 1, the feces inlet cutting part 131b is opened to both sides of the anus.

[0035] The feces inlet cutting part 131b may have all shapes in which the feces inlet cutting part 131b may be elongated in the lengthwise direction of the skin contact layer and may be, for example, linear, rectangular, and elliptical.

[0036] This is intended to be worn and maintained in alignment with an exact position of the user's anus and is not limited to one shape.

[0037] In addition, even if the urinary tract of the wearer 1 is positioned above the skin contact layer 130, the urine may be easily transferred to the absorber 111 through the urine inlet cutting part 131a.

[0038] When the urine inlet cutting part 131a is significantly opened and the urineary track portion of the wearer 1 and the cover layer 120 come into contact with each other, the wearer may feel discomfort due to the absorbed urine, and as a result, it is preferable that the buttocks and the urinary tract portions of the wearer and the cover layer 120 are not in contact with each other.

[0039] At least one urine inlet cutting part 131a may be formed and may be formed so that the urine may flow in the lengthwise direction of the skin contact layer 130 or in any direction.

[0040] Since the urine inlet cutting part 131a is formed as in the present invention, a speed at which the urine is transferred to the absorber 111 through the urine inlet cutting part 131a is faster than a speed at which the urine passes through a nonwoven fabric and is transferred to the absorber 111 in the related art, and as a result, the skin contact layer 130 may be maintained in a dried state.

[0041] In Further, in order to maintain the dried state, it is preferable to use a hydrophobic material rather than a hydrophilic material.

[0042] When the hydrophobic material is used, the urine flows over the hydrophobic material to be absorbed by the absorber 111 through the urine inlet cutting part 131a, and the backflow of the urine to the skin contact layer 130 may be reduced.

[0043] As another material of the skin contact layer 130, it is preferable to use a skin contact layer 130 made of a natural material made of cotton for a user of which skin is sensitive to synthetic fibers and if necessary, powder for reducing moisture or a material to which a skin moisturizing agent, and a skin care material such as oil or aloe are added may be selectively used.

[0044] In order to make the skin contact layer 130 more closely contact with the skin, if the diaper is formed in a state in which an elastic film or the nonwoven fabric which are laminated with the filament and are slightly pulled, the skin contact layer 130 may be brought into closer contact with the skin of the buttocks by elasticity of the material to shrink.

[0045] Herein, the portion of the skin contact layer 130 where the urine inlet cutting part 131a is formed may be formed in close contact with the cover layer 120.

[0046] Further, a wing layer (not illustrated) having a leakage preventing function may be further formed in the lengthwise of the periphery of the upper end of the skin contact layer 130 so as to prevent the urine and the feces 10 from leaking to a thigh.

[0047] As illustrated in FIG. 5, when the base layer 110 and the skin contact layer 130 are coupled to each other, a portion located outside the second elastic member 132, that is, an end 133 located at the edge of the skin contact layer 130 and an inner end 115 of the base layer 110 located inside the first elastic member 112 are bonded to couple the base layer 110 and the skin contact layer 130 to each other and while the base layer 110 and the skin contact layer 130 are coupled to each other, the first elastic member 112 of the base layer 110 is preferably located outside the second elastic member 132 of the skin contact layer 130.

[0048] Further, the second elastic member 132 is brought into close contact with the buttocks of the wearer 1 and the first elastic member 112 is brought into close contact with the thigh region of the wearer 1 so that a receiving space 140 is formed in the space between the buttocks of the wearer 1 and the thigh, that is, between the upper end of the base layer 110 provided with the first elastic member 112 and the lower end of the skin contact layer 130 provided with the second elastic member 132.

[0049] In this case, it is preferable that a plurality of second elastic members 132 may be provided according to the degree of elasticity of the second elastic member 132.

[0050] Further, the feces 10 which is introduced through the inlet cutting part 131 may be received by the receiving space 140.

[0051] Herein, the receiving space 140 may further include a separation membrane (not illustrated) so that the feces 10 drawn through the feces inlet cutting part 131b is separated without being moved in a direction in which the urine inlet cutting part 131a is formed.

[0052] Thus, the present invention has the effect of preventing a feces 10 from touching the vagina and the urinary tract of the female by preventing the feces 10 from moving toward the lower end in which the urine inlet cutting part 131a is formed.

[0053] The present invention has the effect of maintaining the inner surface of the diaper, which is in contact with the skin of the wearer, in a clean and dry state and preventing the skin of the buttocks of the wearer from being contaminated or damaged.

[0054] The disposable diaper as described above is not limited to the configurations and the operation methods of the embodiments described above. The above embodiments may be configured so that all or some of the embodiments may be selectively combined to make various modifications.
