Detailed Description

The following describes the embodiments of the present utility model further with reference to the drawings. The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, the technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

Definition of the definition

The front part refers to the part of the anti-leakage bottom layer of the trousers body part, which is attached to the front surface of the baby body, relative to the body of the baby when standing; the urine point is the part of the pants body part of the diaper attached to the genital organs of babies, and is generally the middle part of the pants body part; the "rear" refers to the portion of the panty body where the leak-proof bottom layer is attached to the back of the baby, i.e., near the buttocks.

With respect to a diaper that is opened and laid on a horizontal plane and has a length and a width, "longitudinal" refers to a direction parallel to the length of the diaper and parallel to the horizontal plane, "transverse" refers to a direction parallel to the width of the diaper and parallel to the horizontal plane, "longitudinal length" refers to a dimension measured in the longitudinal direction, and "transverse length" refers to a dimension measured in the transverse direction.

As shown in figure 1, the breathable paper diaper provided by the utility model comprises a waistline part 1 and a pants body part 2, wherein rubber strings are arranged in the waistline part 1, so that the waistline part 1 is tightly attached to the waist of a baby, and the baby is not easy to loose when wearing the paper diaper. Likewise, the edge of the trouser body part 2 is also internally provided with rubber bands, so that the edge of the trouser body part 2 is clung to the periphery of the thighs of the baby.

As shown in fig. 1-7, the trousers body part 2 comprises a surface layer 21, an absorption core layer 22 and a leakage-proof bottom layer 23 from top to bottom, wherein the surface layer 21 is made of cotton and is directly contacted with the skin of a baby, so that urine can be promoted to quickly permeate; the absorbent core layer 22 is mainly a layered structure composed of a cotton core and superabsorbent resin particles SAP, and is capable of capturing and rapidly absorbing and dispersing urine, and finally absorbing and storing urine. In general, it is known that urine is only stored in the position of the panty portion 2 at the urine point in combination with the body structure of the baby, and the front and rear portions of the panty portion 2 are in a relatively dry state. The absorbent core layer 22 having a layered structure composed of a cotton core and superabsorbent resin particles SAP is relatively breathable in the absence of urine.

Of course, in some embodiments, a diversion layer is further disposed between the top layer 21 and the absorbent core 22, and the diversion layer is made of a nonwoven fabric, and is used to transfer urine received by the top layer 21 to the absorbent core 22, and is a bridge for transferring the top layer 21 and the absorbent core 22.

As shown in FIG. 3, the anti-leakage bottom layer 23 has the functions of anti-leakage and main body supporting, and a plurality of tangential holes 311 are cut out by a cutter at the front part of the anti-leakage bottom layer 23 and/or the rear part of the anti-leakage bottom layer 23, wherein the length of each tangential hole 311 is 3-15 mm, preferably 10mm. When a baby wears the diaper, the body part 2 is slightly deformed, so that the plurality of tangential holes 311 are pulled, the tangential holes 311 are slightly opened, and air can penetrate through the absorbent core layer 22 from the tangential holes 311 and circulate in the diaper, thereby making the baby feel comfortable. When the baby wears the diaper, a gap exists between the diaper and the baby's body, so that air passing through the absorbent core 22 from the tangential holes 311 can circulate in the diaper.

According to the above, urine is only stored in the position of the panty portion 2 at the urine point, and the front and rear portions of the panty portion 2 are in a relatively dry state, so that urine does not leak from the tangential holes 311 at the front and rear portions of the leakage preventing layer 23, and the circulation of air at the tangential holes 311 is not affected.

As shown in fig. 6 to 7, the leakproof bottom layer 23 is formed by laminating and combining a waterproof film 231 and a bottom film 232, the waterproof film 231 is located between the absorbent core layer 22 and the bottom film 232, and a plurality of tangential holes 311 are formed in the waterproof film 231. The waterproof film 231 is made of PE, and has good waterproof performance but poor air permeability; the bottom film 232 is made of non-woven fabric, and has good air permeability but poor water resistance. The leak protection bottom 23 adopts waterproof membrane 231 and backing film 232 to fold the system and combines to form, compares singly to adopt waterproof membrane 231, and on the one hand is more pleasing to the eye, and on the other hand, owing to waterproof membrane 231 (PE material) deformation volume is big, and the deformation volume of backing film 232 (non-woven fabrics material) is little, and through waterproof membrane 231 and backing film 232 fold the system and combine to form, can avoid because of a plurality of tangent lines hole 311 on the waterproof membrane 231 are pulled excessively, lead to tangent line hole 311 to open the scale too big, and the problem that the super absorbent resin granule SAP of existence is unaesthetic, weeping and falling out absorption sandwich layer 22.

As a preferred embodiment thereof, as shown in fig. 3, a plurality of tangential holes 311 are respectively distributed in the longitudinal direction and the transverse direction, and a ventilation area 3 is formed between the longitudinal tangential holes 311 and the transverse tangential holes 311, and the ventilation area of the ventilation area 3 is relatively large. The longitudinal length of the ventilation zone 3 is 30-110 mm, preferably 80mm; the transverse length of the ventilation zone 3 is 30-110 mm, preferably 80mm, so that the ventilation zone can ensure sufficient ventilation and meanwhile the possibility of liquid leakage caused by overlarge area is avoided.

As a preferred embodiment thereof, as shown in fig. 4, a plurality of tangential holes 311 are arranged in a lateral direction at intervals to form a row of tangential hole groups 31, and the plurality of tangential hole groups 31 constitute the ventilation zone 3 described above. The distance between the adjacent tangential holes 311 of the tangential hole group 31 is 3-15 mm, preferably 10mm, and the tangential holes 311 of the tangential hole group 31 of the adjacent rows are arranged in a staggered manner, so that the overall structural strength and the aesthetic degree of the ventilation area 3 are ensured, and meanwhile, the ventilation area 3 can achieve a relatively good ventilation effect.

As some examples, as shown in fig. 5, a plurality of tangential holes 311 are spaced apart in the longitudinal direction to form a row of tangential hole groups 31, and the plurality of rows of tangential hole groups 31 constitute the ventilation area 3. The distance between the adjacent tangential holes 311 of the tangential hole group 31 is 3-15 mm, preferably 10mm, and the tangential holes 311 of the tangential hole group 31 of the adjacent row are arranged in a staggered manner, so that the overall structural strength and the aesthetic degree of the ventilation area 3 are ensured, and meanwhile, the ventilation area 3 can achieve a relatively good ventilation effect.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
