The present invention relates to a diaper, and more particularly, to a diaper having the harmlessness of a cotton fabric diaper and the convenience of a disposable diaper.

In general, diapers are used to collect feces in patients with impaired behavior or in infants who do not have feces. In general, diapers have been emphasized on absorbency, and the improvement in absorbency has been largely achieved by disposable diapers.

This disposable diaper contributes greatly to the urination of the urine of an adult patient, and is also widely used for infants due to its convenience. However, disposable diapers are exposed to chemical treatments several times in the manufacturing process.

Thus, disposable diapers themselves contain large amounts of harmful components. This harmful component is harmful to both adult patients and infants, but it is even more lethal for infants who have not yet adapted to the outside environment.

Thus, although disposable diapers are used for adult patients, more and more people use cotton fabric diapers which are harmless to infants while taking some inconvenience.

However, it is true that cotton fabric diapers are less convenient than disposable disposable diapers and have less absorbent performance. That is, cotton fabric diapers are used to fold thin cotton fabrics several times to form an absorbent layer and to fill the diapers with infants using rubber bands.

This cotton diaper spends a lot of time in the process of folding the diaper after washing as described above, and is also filled by using a separate rubber band, causing a lot of inconvenience even in the process of filling the diaper.

The present invention has been made to solve the problems described above, and an object thereof is to provide a diaper which improves convenience while using cotton fabric which is harmless to the human body.

1 is a perspective view of a diaper according to a first embodiment of the present invention, Figure 2 is a cross-sectional view taken along the line II-II of FIG.

Referring to these figures, the diaper 100 is formed including an endothelial 10, an outer shell 20, absorbent bands 30, and a tarp 40.

The inner shell 10 and the outer shell 20 substantially determine the shape of the diaper 100, are formed to be substantially the same size with respect to the plane direction (in the unfolded state on the floor) and are arranged to face each other, It is formed in an integral structure by the sewing material 11 along its outer circumference.

The endothelial 10 and the outer shell 20 may be directly finished by sewing the nested end, but the outer periphery is connected to the sewing material 11 through the finishing material 12. Therefore, the phenomenon that the endothelial 10 and the outer shell 20 are loosened at the end of the diaper 100 during use and washing can be prevented.

The inner skin 10 and the outer skin 20 superposed on each other are formed in a rectangular shape, for example, and are used in a state of being folded many times. The inner shell 10 and the outer shell 20 are formed in a size that can be folded and used a plurality of times, this embodiment illustrates a diaper 100 is used to fold twice (once folded shape: see Figure 3, twice Folded shape: see FIG. 4).

In addition, the inner shell 10 and the outer shell 20 may be formed in a rectangular shape, but this embodiment illustrates that formed in a square shape. When the diaper 100 formed of the square inner shell 10 and the outer shell 20 is folded twice, the diaper 100 has a rectangular shape suitable for use by filling the infant.

The inner shell 10 forms an inner surface of one side of the inner and outer surfaces of the diaper 100, and the outer shell 20 forms the other surface of the diaper 100, that is, the outer surface.

The inner shell 10 and the outer shell 20 may be formed of the same material and the same thickness. In this case, the diaper 100 can be used on both sides without distinguishing the inner surface and the outer surface, and maintains a high wearing feeling in any case.

The endothelial 10 is a portion directly contacting the skin of the infant, and may be formed of cotton or circular knitted fabric, or may be formed by raising the surface of the cotton or circular knitted fabric (see FIG. 18).

The cotton or circular knitted fabric and the endothelial 10 and the outer shell 20 brushed on these surfaces are thus highly breathable and provide a good fit to the infant.

The absorbing bands 30 are formed in multiple layers to form a layer with the endothelium 10 and the envelope 20 (see FIG. 2).

The absorption bands 30 may have different absorption effects depending on which layer is formed in the relationship with the endothelium 10 and the outer shell 20 as a portion that determines the absorption performance.

When the absorbent bands 30 are interposed between the endothelium 10 and the outer shell 20 as in the first embodiment, the endothelium 10 acts as an absorption start portion in the diaper 100 to influence absorption start performance. The absorption bands 30 serve as a portion absorbing and absorbing and storing through the endothelium 10 to influence the absorption and storage performance.

The absorbing bands 30 are formed in multiple layers between the endothelium 10 and the outer shell 20. For example, the first absorbing band 31, the second absorbing band 32, and the third absorbing band 33 may be formed. It is formed to include.

For this absorption and storage performance, the first absorption zone 31 is disposed at the endothelial 10 side, the third absorption zone 33 is disposed at the outer shell 20 side, and the second absorption zone 32 is the first absorption zone 32. It is arranged between 31 and the second absorption zone 32. Accordingly, urine absorbed through the endothelium 10 is stored while being sequentially absorbed into the first absorption band 31, the second absorption band 32, and the third absorption band 33.

At this time, the first absorption zone 31 has a larger absorption force than the second absorption zone 32, and the second absorption zone 32 has a larger absorption force than the third absorption zone 33. Accordingly, the urine absorbed through the endothelium 10 is absorbed and stored in the first absorbent band 31 and gradually absorbed and stored in the first absorbent band 31 and the third absorbent band 33. Therefore, urine or the like becomes difficult to bleed out of the diaper 100.

These absorbing bands 30 may be formed of cotton or circular knitted fabric paper, or may be formed by raising the surface of the cotton or circular knitted fabric paper (see FIG. 18).

The cotton or circular knit fabric and the absorbent bands 30 brushed on these surfaces have high air permeability, such as the endothelium 10 and the shell 20, and provide higher absorption performance.

On the other hand, the waterproof bag 40 is such that the urine absorbed as described above does not flow out or bleed out through the outer shell 20, it is contained in the endothelial 10 and the absorption band 30, to the cotton fabric and knitted fabric The endothelial 10 and the absorption zone 30 configured can be effectively used as the diaper 100.

The tarpaulin 40 is interposed between the absorption bands 30 and one of the inner skin 10 and the outer skin 20, for example, to be formed of a thermoplastic polyurethane (TPU: Temperature polyurethane) excellent in waterproof performance Can be.

For example, the waterproofing band 40 and the absorbing bands 30 are formed by a third area of an area of the inner shell 10 and the outer shell 20 having a rectangular shape, and thus the inner shell 10 and the outer shell 20. ) Is disposed in the third zone (15) of the first, second, and third zones (13, 14, 15) divided into three.

At this time, the waterproof belt 40 is used to the minimum to enable the waterproof operation of the diaper 100 while reducing the cost. In addition, the absorption bands 30 prevent the diaper 100 from being thickened unnecessarily when the inner skin 10 and the outer skin 20 are folded.

That is, the absorption bands 30 and the waterproofing band 40 are formed in a rectangular shape in which the inner shell 10 and the outer shell 20 are divided into three and are superimposed on each other. The three sides of the absorbent bands 30 and the tarpaulin 40 are sewn 11 and fixed together with the endothelium 10 and the sheath 20 via the finish 12. And the other side of the absorption bands 30 and the waterproofing band 40 is sewn in a zigzag stitch line (16) is fixed to the endothelium 10 and the outer shell (20).
