In addition, the moisture absorbed by the diaper according to the present invention includes not only urine excreted in the body but also moisture contained in the excreted feces in the body. Hereinafter, the term 'urine' refers to the amount of water contained in the urine and feces excreted in the body It is a concept to include.

That is, the diaper according to the present invention has a structure in which the outer layer 10, the absorbent layer 20, the backflow preventing layer 30 and the inner layer 40 are stacked from the bottom to the top, The backflow preventing layer 30 may be formed on the backside of the honeycomb structure.

Specifically, the outer layer 10 has a structure having a waterproof material and is formed outside the diaper.

At this time, the outer layer 10 may have various types of images formed on its surface, and the outer layer 10 may be formed in a straight shape so as to be worn around a part of the body corresponding to the buttocks, crotch, Or a panty-type, and a plurality of portions may be subjected to the banding treatment so that the urine discharged by the wearer does not flow out to the outside of the diaper.

The outer layer 10 is composed of an inner outer layer 10 made of a waterproof material and an outer outer layer 10 made of natural fiber (or synthetic fiber) so as to secure a better feel for the wearer. And the following absorbent layer 20 may be formed on the inner outer layer 10.

In addition, the absorbent layer 20 is formed on the outer layer 10 to absorb the urine discharged from the diaper, and is composed of an absorbent material, an absorbent fiber, or an absorbent surface.

At this time, the absorbent material or the absorbent fiber that can constitute the absorbent layer 20 may include a water absorbent composition having an ability to absorb moisture, or may be a granular or fiber-like structure made of an absorbent composition, &Lt; / RTI >

The backflow preventing layer 30 is formed on the upper portion of the absorbent layer 20 and has a plurality of downward protruding portions 31 formed with recesses 32 that are narrowed from the upper portion to the lower portion. The inner layer 40 is formed on the backflow preventing layer 30.

That is, the inner layer 40 may be formed of a synthetic resin material of a natural material or a kind of less harmful to the human body in order to minimize the skin troubles of the wearer, which is formed on the top of the diaper.

The backflow preventive layer 30 is provided between the absorbent layer 20 and the inner layer 40 as a main point of the present invention so that the urine discharged by the wearer passes through the inner layer 40, And is prevented from flowing back toward the inner layer 40 after being absorbed.

At this time, the backflow preventive layer 30 is configured such that the urine can flow quickly from the inner layer 40 to the absorbent layer 20, while the urine flowing into the absorbent layer 20 does not flow back to the inner layer 40 However, it is preferable that a plurality of downward protrusions 31 are formed as shown in FIGS. 2A and 2B in which grooves 32 are formed so as to be narrowed from the top to the bottom.

That is, the downward protruding portion 31 protrudes to the lower portion of the backflow preventing layer 30 when viewed from a vertical sectional state of the backflow preventing layer 30, and the downward protruding portion 31 is formed such that the downward protruding portion 31 has, The urine flowed to the upper portion of the backflow preventing layer 30 in the inner layer 40 flows into the upper portion of the groove 32 having the larger inner diameter and the lower portion of the narrowed inner groove 32 So that it can flow into the absorbent layer (20).

At this time, the urine flowing into the absorbent layer 20 from the lower portion of the groove 32 is absorbed by the absorbent layer 20 and even if the urine absorbed in the diarrhea absorbent layer 20 is discharged from the absorbent layer 20, 32 so that the backflow of urine from the absorbent layer 20 to the inner layer 40 is blocked.

The backflow preventing layer 30 may be formed in various shapes as long as the plurality of downward protruding portions 31 are formed to have a predetermined area in the overall area of the backflow preventing layer 30, And a waterproof material film formed thereon.

The backflow preventing layer 30 is configured to have an area covering the upper portion of the absorbent layer 20 so as to block the entire urine that can flow back from the absorbent layer 20 to the inner layer 40 .

In addition, the plurality of downward protrusions 31 flow from the absorbent layer 20 through the lower part of the groove 32 of the narrow inner diameter to the inside of the absorbent layer 20 through the upper part of the groove 32 of the wide inner diameter, The lower downward protrusion 31 may be formed in various shapes as long as it can block the urine backflow into the layer 40. More preferably, And the upper portion of the groove 32 of the other downward projection 31 may be directly connected.

That is, the downwardly projecting portion 31 of the above-described structure is formed so that the upper portion of the groove 32 formed in any one downwardly projecting portion 31 and the upper portion of the groove 32 formed in another downwardly projecting portion 31 adjacent thereto are maximally adjacent So that the horizontal area formed by the upper portion of the groove 32 of the downward protrusions 31 is widened so that the urine flowing from the inner layer 40 to the backflow prevention layer 30 flows into the recess 32 To the absorbent layer 20 through the openings (not shown).

In addition, a plurality of radial protruding jaws 33 may be formed on the lower surface of the downward protruding portion 31, with the lower portion of the groove 32 as a center and a height downward.

3A and 3B, since the radial protruding protuberance 33 is formed downward at a predetermined height from the lower portion of the downward protruding portion 31, A part of the urine absorbed on the lower surface of the protruding portion 31 is separated from the absorbent layer 20 by its own weight or external pressure and then the lower protruding portion 31 is moved downward along the lower surface of the downward protruding portion 31 to the lower portion of the groove 32 And prevents some of the flowing down urine from flowing backward through the groove (32) formed in the lower portion of the downward projecting portion (31).

At this time, since the radial protrusion 33 forms a certain height downward from the lower surface of the downward protrusion 31, the urine which flows down along the lower surface of the downward protrusion 31, So that the absorbing layer 20 can be absorbed again before being introduced.

Since the radial protruding protuberance 33 having the above-described configuration is annular around the lower portion of the groove 32 and forms a plurality of radial layers on the lower surface of the downward protruding portion 31, any one of the radial protruding protuberances 33 The urine which is not blocked by the downward flow can be prevented again by the other radial protruding jaws 33 adjacent to the lower portion of the groove 32. [

In addition, the downward protrusion 31 is formed to have a straight flow pipe 34 formed with a flow path, and the straight flow pipe 34 can be inserted into the absorption layer 20.

4A and 4B, the linear flow pipe 34 has a structure in which urine absorbed in the absorbent layer 20 is prevented from flowing back through the lower portion of the groove 32, And the lower end is extended from the upper end to the lower end by a predetermined length to be inserted into the absorbent layer 20.

At this time, the urine flowing into the groove 32 in the inner layer 40 flows into the hollow of the straight flow tube 34 through the lower portion of the groove 32 and then flows out to the lower end of the straight flow tube 34, 20, and the urine absorbed in the absorbent layer 20 can flow back into the groove 32 through the hollow of the straight flow tube 34, thereby reducing the possibility of backflow of the urine.

In addition, the length of the straight flow tube 34 having the above-described configuration can be appropriately adjusted according to the judgment of a person skilled in the art, and more preferably, the lower end of the straight flow tube 34 is located in the middle or more of the thickness of the absorbent layer 20 It is desirable to have a length that can be as large as possible.

That is, when the lower end of the straight flow pipe 34 is positioned at a lower part than the middle of the thickness of the absorbent layer 20, the length of the straight flow pipe 34 is long, The flow rate of the urine flowing from the groove 32 to the absorbent layer 20 is somewhat lowered and the flow rate of the urine from the inner layer 40 to the groove 32 is lowered. The urine flow rate may be lowered.

Also, the lower end of the straight flow pipe 34 may be provided with a funnel 35 in the form of a reverse phase for preventing diffusion and backflow that becomes wider from the upper part to the lower part.

5a and 5b, the upper portion connected to the lower end of the straight flow pipe 34 has a hollow inner diameter and the lower portion has a hollow having a larger inner diameter, The urine flowing in the lower portion of the flow tube 34 spreads in the cavity of the reverse phase funnel 35 and flows into the absorbent layer 20 to be more easily absorbed into the absorbent layer 20 and absorbed into the absorbent layer 20 (Particularly urine absorbed in the absorbent layer 20 at the upper side of the outer side of the funnel 35 of the reversed phase) flows into the liquid flow pipe 34 due to the inclination of the upper portion of the outer side of the funnel 35 in the reverse phase. The effect of preventing the backflow to the hollow easily.

At this time, the degree of spreading by the inclination of the upper and lower portions of the funnel 35 may be configured to have various inclination angles depending on the use and the wearer of the diaper.

The curved flow pipe 36 may be inserted into the absorbent layer 20. The curved flow pipe 36 may be formed with a curved flow pipe 36 having a flow path formed under the downward protruding portion 31. [

That is, the curved flowtube is configured to prevent the urine absorbed in the absorbent layer 20 from flowing back through the lower portion of the groove 32, similar to the straight flow tube 34, as shown in FIGS. 6A and 6B An upper end is connected to a lower portion of the groove 32 and a lower end is formed to extend from the upper end to the lower end to form a predetermined length and to be inserted into the absorbent layer 20. [

At this time, the urine flowing into the groove 32 in the inner layer 40 flows into the hollow of the curved flow tube through the lower portion of the groove 32 and then flows out to the lower end of the curved flow tube to be absorbed by the absorbing layer 20, Since the urine absorbed in the absorbent layer 20 can flow back into the groove 32 through the hollow of the curved flowtube, the possibility of backflow of the urine is reduced.

In addition, since the curved flowtube is extended from the upper part to the lower part connected to the lower part of the groove 32 and a certain part of the middle part or lower part is bent in the horizontal direction, The backflow of the urine can be blocked in the curved portion of the curved flow tube even if the urine flows back to the hollow end formed at the lower end.

In addition, the length of the curved flow tube of the above-described configuration can be appropriately adjusted according to the judgment of a person skilled in the art, and more preferably, the length of the curved flow tube is such that the lower end thereof can be located at a middle portion of the thickness of the absorbent layer 20 .

That is, when the lower end of the curved flow pipe is positioned at a lower part than the middle of the thickness of the absorbent layer 20, the length of the curved flow pipe is long. Therefore, the urine can flow back to the recess 32 in the absorbent layer 20 The flow rate of the urine flowing from the groove 32 to the absorbent layer 20 is somewhat lowered and the urine flow rate from the inner layer 40 to the groove 32 may be lowered It is because.

The backflow prevention type diaper according to the present invention as described above has the backflow preventing layer 30 formed on the upper part of the absorbent layer 20 which is a portion between the wearer's skin and the absorbent layer 20, It is possible to obtain an effect of preventing the backward flow of urine to the wearer.
