Description

Technical Field

[0001] This utility model relates to the field of diaper technology, specifically to a comfortable and breathable diaper. Background Technology

[0002] Disposable diapers are an indispensable product in childcare. They absorb urine through their absorbent core, greatly reducing the burden of childcare. Diapers are typically thick and cover a large area of ​​the baby's crotch. After urination, the inside of the diaper becomes hot and humid. Because babies' skin is delicate and sensitive, this can easily lead to diaper rash. Therefore, breathability is a key factor for consumers. Good breathability significantly improves comfort, enhances sleep quality, and allows babies more freedom of movement.

[0003] Chinese Patent Publication No. CN213666187U discloses a diaper that is dry and leak-proof, comprising a surface layer. The surface layer includes a hydrophobic layer that contacts the skin and a hydrophilic layer for absorbing water and leak-proof material. The hydrophobic layer is composed of hydrophobic fibers, and the hydrophilic layer is composed of hydrophilic fibers. The hydrophobic layer is disposed within the surface area of ​​the hydrophilic layer, with two sides flush with the two side edges of the hydrophilic layer, and the other two sides having a gap of 1-3 mm between them and the other two side edges of the hydrophilic layer. A guide portion is provided on the side of the hydrophobic layer away from the hydrophilic layer to guide the water and leak-proof material. The liquid on the layer is guided to the gap; the diaper disclosed in this patent has a two-layer structure on the surface. Through the structural design of the hydrophilic layer and the hydrophobic layer, it can keep the area where the diaper contacts the skin dry. However, during use, when the baby's urine is absorbed by the diaper, the space between the diaper and the baby's crotch will be relatively damp. In addition, when the baby urinates, some urine will come into contact with the skin, causing the skin to be in a damp state. If the skin is in this state for a long time, symptoms such as diaper rash may occur. Therefore, there is still room for improvement in this diaper. Utility Model Content

Detailed Implementation

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0023] like Figure 1-6As shown, a comfortable and breathable diaper includes an absorbent area 1, a front waistband 2, and a back waistband 3. The absorbent area 1 is located between the front waistband 2 and the back waistband 3 and is fixedly connected to each other. The absorbent area 1 is composed of a surface non-woven fabric 11, an absorbent core 12, and a leak-proof bottom film 13 in sequence along the thickness direction. Several horizontally extending waistband elastics are provided in the front waistband 2 and the back waistband 3. The absorbent area 1 is recessed inward on both sides to form leg openings 4. The absorbent core 12 is provided with leak-proof partitions 5 near the edges of the leg openings 4 on both sides. The two ends of the leak-proof partitions 5 are fixedly connected to the front waistband 2 and the back waistband 3.

[0024] The leak-proof partition 5 includes the following structure: an adjacent inner partition fabric 51 and an outer partition fabric 52. The surface of the inner partition fabric 51 is covered with a waterproof layer 53. The outer partition fabric 52 is located on the side close to the leg circumference 4 and has several partition ventilation holes 54 through its surface. A partition elastic band 55 extending longitudinally is provided between the inner partition fabric 51 and the outer partition fabric 52. The partition elastic band 55 has a tension elastic band 56 whose end is fixedly connected to the absorbent core 12.

[0025] This invention uses a front waistband 2 and a back waistband 3 to fix the diaper to the waist of the user. The non-woven fabric 11 and the leak-proof bottom film 13 extend outwards at both ends in the longitudinal direction to form the front waistband 2 and the back waistband 3. The non-woven fabric 11 and the leak-proof bottom film 13 together wrap the elastic waistband. The front waistband 2 has front fasteners 21 at both ends in the lateral direction, and the back waistband 3 has rear fasteners 31 at both ends in the lateral direction that match the front fasteners 21. The front fasteners 21 and the rear fasteners 31 preferably use matching Velcro to fasten the front fasteners 21 and the rear fasteners 31. After the fasteners 31 are glued together, the front waistband 2 and the back waistband 3 form an elastic waistband that is connected end to end. The elastic waistband wraps around the waist of the human body through the internal waistband elastic, preventing the diaper from falling off. Furthermore, the front fasteners 21 and the back fasteners 31 use Velcro, which makes it easier to adjust the circumference of the elastic waistband, thereby adjusting the tightness of the elastic waistband and preventing the elastic waistband from constricting the human body too much. After the diaper is fixed by the elastic waistband, the absorbent area 1 wraps around the crotch of the human body, and the absorbent core 12 inside the absorbent area 1 absorbs the excreted urine.

[0026] In the absorption area 1 of this invention, the surface nonwoven fabric 11 is in direct contact with the human body. It is preferably made of comfortable spunlace nonwoven fabric, hot-air nonwoven fabric, etc. The surface nonwoven fabric 11 can be perforated by mechanical punching to form several liquid-permeable pores on the surface, which improves the efficiency of urine permeation to the absorbent core 12. The surface nonwoven fabric 11 can also be hot-pressed to form several longitudinally extending diffusion grooves on the surface, which promotes the longitudinal diffusion of urine. The absorbent core 12 adopts a common structure of nonwoven fabric wrapping the internal water-absorbing resin and fluff pulp. The high water absorption performance of the water-absorbing resin and fluff pulp absorbs and locks in the urine. The leak-proof bottom film 13 is preferably a waterproof and breathable polyethylene film. During the molding process of the waterproof and breathable polyethylene film, several breathable but waterproof micropores are formed. These micropores can discharge some of the moisture inside the diaper and improve the breathability inside the diaper. They also prevent urine from penetrating to the surface of the diaper and causing urine to stain the bed and other places.

[0027] The leg circumference 4 on both sides of the absorbent area 1 is used to wrap around the upper thigh. Two leak-proof partitions 5 are located at the upper thigh on both sides. The leak-proof partitions 5 are wrapped with the partition elastic 55 by the inner partition fabric 51 and the outer partition fabric 52. The partition elastic 55 makes the leak-proof partitions 5 and the leg circumference 4 fit tightly against the upper thigh. The two ends of the partition elastic 55 are stretched by the front waistband 2 and the back waistband 3, so that the leak-proof partitions 5 stand up above the surface non-woven fabric 11, thus forming a barrier on both sides of the absorbent core 12. The inner partition fabric 5 1. The outer side panel 52 is preferably made of waterproof non-woven fabric. The inner side panel 51 covers the side of the waterproof layer 53 near the center of the surface layer and is formed by coating the surface of the inner side panel 51 with waterproof coating. When the user urinates too much and the absorbent core 12 cannot absorb all the urine in a short time, some urine will flow laterally along the surface of the non-woven fabric 11 until it comes into contact with the leak-proof side panel 5. The waterproof layer 53 prevents urine from penetrating the leak-proof side panel 5 and prevents urine from continuing to flow laterally and causing side leakage, so that the diaper has a side leakage prevention effect.

[0028] In addition, the space between the non-woven fabric 11 of the diaper and the human body is isolated from the outside air by the leak-proof partition 5. Several ventilation holes 54 on the surface of the partition non-woven fabric can serve as a structure to connect the space with the outside air, improve the breathability of the diaper, and facilitate the expulsion of moisture in the space, keeping the human skin surface dry and improving the comfort during the use of the diaper.

[0029] With the above structure, it should be further explained that the elastic band 55 is located at the top of the leak-proof partition 5, and the end of the tension elastic band 56 away from the absorbent core 12 is fixedly connected to the elastic band 55. The tension elastic band 56 and the partition ventilation holes 54 are staggered. The tension elastic band 56 can form several folds on the surface of the inner partition fabric 51 and the outer partition fabric 52 through elastic contraction. These folds will compress the pore size of the partition ventilation holes 54 on the surface of the outer partition fabric 52, but the outer partition fabric 52 can maintain a certain degree of air permeability. When the absorbent core 12 absorbs urine, its weight will increase, and the paper... The absorbent area 1 of the diaper needs to withstand greater gravity and will sag to a certain extent. The sag of the absorbent core 12 will exert a downward pulling force on the elastic band 56, causing the elastic band 56 to stretch and lengthen. This will keep the leak-proof side panel 5 in a stretched state, reduce the pleat density on the surface of the outer side panel 52 and enlarge the pore size of the side panel ventilation holes 54, thereby improving the breathability of the outer side panel 52. Moisture generated by urine will penetrate the inner side panel 51 and be discharged to the outside through the side panel ventilation holes 54, preventing moisture from remaining inside the diaper and causing symptoms such as diaper rash, thus improving comfort.

[0030] Furthermore, the waist elastic band, side elastic band 55, and stretch elastic band 56 of this utility model are preferably made of fine denier spandex yarn. Fine denier spandex yarn has good softness, which can prevent the waist and leg areas of the diaper from constricting the body, thereby improving the comfort of the diaper.

[0031] like Figure 3 , 4 As shown, in one of the preferred embodiments of this utility model, a plurality of guide wires 57 are provided between the inner partition fabric 51 and the outer partition fabric 52. The guide wires 57 are preferably hollow fibers with good liquid properties. The hollow fibers can generate capillary effect through the internal capillaries to promote the flow of liquid along their extension direction. The extension direction of the guide wires 57 is the same as the extension direction of the stretching elastic band 56. When there is too much urine flowing laterally on the surface of the nonwoven fabric 11, a small amount of urine may penetrate the inner partition fabric 51 and seep into the space between the inner partition fabric 51 and the outer partition fabric 52. This urine will come into contact with the guide wires 57. The guide wires 57 can promote the flow of urine toward the absorbent core 12 and be absorbed, thereby improving the side leakage prevention effect of the leak-proof partition 5.

[0032] like Figure 1 As shown, in one of the preferred embodiments of this utility model, the front waistband 2 and the back waistband 3 are both perforated with a number of waistband ventilation holes 6. The waistband ventilation holes 6 are arranged alternately with the waistband elastic. Since the front waistband 2 and the back waistband 3 are both close to the waist of the human body, the waist area of ​​the human body is prone to sweating. If the sweat stays in the waist area for a long time, it can easily lead to symptoms such as eczema on the waist skin. By setting the waistband ventilation holes 6, the front waistband 2 and the back waistband 3 can improve the air circulation between the waist area and the outside and expel moisture, keeping the waist area of ​​the human body dry and further improving the breathability of the diaper.

[0033] like Figure 3 , 5 As shown in Figure 6, in one of the preferred embodiments of this utility model, the absorbent core 12 is composed of a flow guiding layer 121, a first diffusion layer 122, an absorber 123, and a second diffusion layer 124 in sequence along the thickness direction. The flow guiding layer 121 is preferably spunbond nonwoven fabric. The flow guiding layer 121 promotes the rapid penetration of liquid in the surface nonwoven fabric 11 into the interior of the absorbent core 12. The first flow guiding layer 121 and the second flow guiding layer 121 are preferably meltblown nonwoven fabric. The meltblown nonwoven fabric is composed of fine fibers, which can promote the large-scale diffusion of liquid in the horizontal direction. The diffused liquid can be uniformly absorbed by the absorber 123 over a larger area, improving the absorption efficiency of the liquid. The absorber 123 is composed of a certain proportion of water-absorbing resin and fluff pulp. Through the good water absorption of these two materials, the liquid is absorbed into the interior and locked to prevent liquid backflow.

[0034] In summary, the absorbent core 12 of this invention has leak-proof side panels 5 on both sides to prevent side leakage. The non-woven fabric 51 of the side panels 5 has several side ventilation holes 54. The side ventilation holes 54 improve the air circulation between the diaper crotch and the outside, keeping the skin surface dry. When the diaper absorbs urine, the absorbent core 12 will drop and the elastic band 56 will be stretched, increasing the pore size of the side ventilation holes 54 and improving the breathability of the diaper. The side ventilation holes 54 can more efficiently expel the moisture generated by urine, thus keeping the fabric in the diaper crotch dry. The diaper of this invention has good breathability and comfort.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
