Technical Field

[0001] The invention relates to the field of sanitary products, in particular to a baby diaper. Background Art

[0002] At present, the structure of baby diapers on the market mainly includes an outer cover, an absorbent body, a leak-proof barrier wall, elastic leg bands and a rear connecting waistband. The outer cover includes a non-permeable outer layer and a permeable inner layer. The absorbent body is located between the non-permeable outer layer and the permeable inner layer and is fixed along the edge of the absorbent body by glue. The leak-proof barrier wall, elastic leg bands and the rear connecting waistband are all fixed to the outer cover by glue. The rear connecting waistband is provided with a magic buckle. When in use, the rear connecting waistband is closed to enclose the diaper and put it on the body. After the absorbent core absorbs too much urine, it will drive the trousers to fall down, thereby forming a gap, which often leads to urine leakage. The existing diapers form a closed space after being worn on the baby, and the internal ventilation is often poor, which can easily cause diaper rash in babies.

[0003] Therefore, it is necessary to improve the baby diapers in the prior art to solve the above problems. Summary of the invention

[0004] The present invention overcomes the deficiencies of the prior art and provides a baby diaper.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a baby diaper, comprising: a body; the body is divided into a front waist area, a trouser body and a back waist area connected together, characterized in that:

[0006] The front waist region comprises: front waist patches arranged on both sides of the front waist region, and a compression umbilical cover arranged in the middle of the front waist region;

[0007] The rear waist region comprises: magic buckles arranged on both sides of the rear waist region, and an elastic waistline arranged on one side of the magic buckles;

[0008] The trouser body comprises: a highly absorbent resin layer arranged inside the trouser body, a salt-sensitive hydrogel arranged on one side of the highly absorbent resin layer, and a plurality of gas storage layers arranged on one side of the salt-sensitive hydrogel; the outer side of the gas storage layer is wrapped with a rubber wrapping layer, a capillary is arranged on the outer side of the gas storage layer, the capillary connects the gas storage layer and the outside, a plurality of the gas storage layers are connected with each other through a connecting pipe, an air outlet pipe is arranged on one side of the gas storage layer, and the air outlet pipe passes through to the front of the front waist area and the front of the back waist area.

[0009] In a preferred embodiment of the present invention, the front waist patch is adhered in cooperation with the magic buckle, the material of the front waist patch is a hydrophilic non-woven fabric, and the material of the magic buckle is polyester fiber and polyamide fiber.

[0010] In a preferred embodiment of the present invention, the gas storage layer is made of TPU plastic, and the rubber wrapping layer stretches the gas storage layer into a hollow elliptical shape when no external force is applied.

[0011] In a preferred embodiment of the present invention, a plurality of the gas storage layers are arranged in an array inside the trouser body.

[0012] In a preferred embodiment of the present invention, a plurality of water absorption holes are provided on the front side of the trouser body, the front side of the trouser body is made of a hydrophilic non-woven fabric, and the back side of the trouser body is made of a PP or PE material.

[0013] In a preferred embodiment of the present invention, the compression umbilical cover is made of multi-layer hydrophilic non-woven fabric.

[0014] In a preferred embodiment of the present invention, three-dimensional guards are provided on both sides of the trouser body, and the three-dimensional guards are made of PP or PE material.

[0015] The present invention provides a method for using a baby diaper, which is characterized by comprising the following steps:

[0016] When urine enters the inside of the pants at a certain point on the front side, it is absorbed and expanded by the super absorbent resin layer. The salt-sensitive hydrogel here will swell when it encounters the salt in the urine. The super absorbent resin layer will fit the baby when it is squeezed toward the front side of the pants, and the air storage layer at the corresponding part will be compressed when it is squeezed toward the back side of the pants, and the air in the air storage layer will be discharged through the air outlet pipe.

[0017] After the urine is absorbed by the super absorbent resin layer, it will gradually diffuse to the super absorbent resin layers in other parts, thereby causing the salt-sensitive hydrogels in other parts to swell. Gradually squeezing toward the front of the pants will fit the baby, and squeezing toward the back of the pants will gradually compress different air storage layers, thereby allowing the air storage layers to continuously exhaust gas.

[0018] In a preferred embodiment of the present invention, when the baby's gravity presses the air storage layer downward, the air storage layer will be compressed under the action of external force and exhaust will be discharged through the exhaust pipe. When the baby's gravity is transferred, the rubber wrapping layer will drive the air storage layer to return to its original state. While returning to its original state, the capillary will introduce air into the air storage layer from the outside.

[0019] In a preferred embodiment of the present invention, before the umbilicus of a newborn baby is completely healed, the compressed umbilical cover can be stretched outward to maintain a certain space with the umbilicus to form an umbilical protection space.

[0020] The present invention solves the defects existing in the background technology and has the following beneficial effects:

[0021] (1) The present invention provides a baby diaper, wherein a super absorbent resin layer, a salt-sensitive hydrogel and an air storage layer are sequentially arranged inside the trouser body. When urine enters the inside at a certain position on the front side of the trouser body, it is absorbed and expanded by the super absorbent resin layer. The salt-sensitive hydrogel here will swell after encountering the salt in the urine. The super absorbent resin layer will be squeezed toward the front side of the trouser body to fit the baby, preventing the super absorbent resin layer from absorbing urine and causing the trouser body to fall down, thereby forming gaps and causing urine to leak sideways. The squeezing toward the back side of the trouser body will compress the air storage layer at the corresponding position, thereby discharging the air in the air storage layer through the air outlet pipe, thereby achieving ventilation.

[0022] (2) In the present invention, a super absorbent resin layer, a salt-sensitive hydrogel and an air storage layer are sequentially arranged inside the trouser body. When urine is absorbed by the super absorbent resin layer, the urine will gradually diffuse to the super absorbent resin layers in other parts, thereby causing the salt-sensitive hydrogels in other parts to swell and gradually squeeze toward the front of the trouser body to fit the baby. Squeezing toward the back of the trouser body will gradually compress different air storage layers, thereby causing the air storage layers to continuously exhaust gas, thereby greatly improving the air permeability inside the diaper.

[0023] (3) In the present invention, a rubber wrapping layer is provided on the outside of the air storage layer. When the rubber wrapping layer is not subjected to external force, the air storage layer will be stretched into a hollow elliptical shape. When the weight of the baby presses the air storage layer downward, the air storage layer will be compressed under the action of the external force to exhaust air through the exhaust pipe. When the weight of the baby is transferred, the rubber wrapping layer will drive the air storage layer to return to its original state. While returning to its original state, the capillary will introduce air from the outside into the air storage layer, so that the air can continue to be stored for the next exhaust.

[0024] (4) The present invention compresses and sets a compression umbilical cord cover in the middle of the front waist area. Before the umbilical cord of the newborn is completely healed, the compression umbilical cord cover can be stretched outward to maintain a certain space with the umbilical cord, forming an umbilical cord protection space, which is easy to ventilate and avoids redness, bleeding or infection caused by direct friction between the front waist area of ​​the diaper and the baby's umbilical cord.

In the description of the invention, unless otherwise specified, "multiple" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0035] like Figure 1 As shown, a baby diaper comprises: a main body; the main body is divided into a front waist area, a trouser body 3 and a back waist area which are connected together.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, the front waist region includes: front waist tapes 1 arranged on both sides of the front waist region, and a compression umbilical cover 101 arranged in the middle of the front waist region.

[0037] The back waist area includes: magic buckles 2 arranged on both sides of the back waist area, and an elastic waist circumference 201 arranged on one side of the magic buckle 2. The elastic waist circumference 201 is made of two layers of non-woven fabric composite spandex yarn, and the two layers are glued together and have a certain elastic range, so that the wearer can fit well and improve the waist leakage prevention ability.

[0038] The trouser body 3 includes: a highly absorbent resin layer 301 arranged inside the trouser body 3, a salt-sensitive hydrogel 4 arranged on one side of the highly absorbent resin layer 301, and a plurality of gas storage layers 5 arranged on one side of the salt-sensitive hydrogel 4; the outer side of the gas storage layer 5 is wrapped with a rubber wrapping layer 501, and a capillary 502 is arranged on the outer side of the gas storage layer 5, the capillary 502 connects the gas storage layer 5 with the outside, and the plurality of gas storage layers 5 are interconnected through a connecting tube 503, and an air outlet pipe 504 is arranged on one side of the gas storage layer 5, and the air outlet pipe 504 penetrates to the front of the front waist region and the back waist region. Under the action of salt, the expansion ratio and water absorption of the salt-sensitive hydrogel 4 will undergo a sudden change.

[0039] The front waist tape 1 is adhered with the magic buckle 2, the material of the front waist tape 1 is hydrophilic non-woven fabric, and the material of the magic buckle 2 is polyester fiber and polyamide fiber. When wearing the diaper, by adhering the magic buckle 2 to the front waist tape 1, the front and back waists form a closed system, which is firmly adhered and can be used repeatedly.

[0040] The material of the gas storage layer 5 is TPU plastic. The rubber wrapping layer 501 stretches the gas storage layer 5 into a hollow ellipse when no external force is applied. Rubber is a type of linear flexible high molecular polymer that can produce a large deformation under the action of external force and can quickly return to its original shape after the external force is removed.

[0041] A plurality of air storage layers 5 are arranged in an array inside the trouser body 3 .

[0042] A plurality of water absorption holes are provided on the front side of the trouser body 3 . The front side of the trouser body 3 is made of a hydrophilic non-woven fabric, and the back side of the trouser body 3 is made of a PP or PE material.

[0043] The compression umbilical cover 101 is made of a multi-layer hydrophilic non-woven fabric, which is compressed and arranged in the middle of the front waist area and can be stretched and bulged outward to form a umbilical protection space.

[0044] Three-dimensional guards 311 are arranged on both sides of the trouser body 3. The three-dimensional guards 311 are made of PP or PE material. When the baby wears the diaper, the three-dimensional guards 311 fit against the baby's thigh roots to prevent urine from penetrating.

[0045] The present invention provides a method for using a baby diaper, which is characterized by comprising the following steps:

[0046] When urine enters the trouser body 3 at a certain point on the front side, it is absorbed and expanded by the super absorbent resin layer 301. The salt-sensitive hydrogel 4 here will swell after encountering the salt in the urine. The super absorbent resin layer 301 will be pressed toward the front side of the trouser body 3 to fit the baby, preventing the super absorbent resin layer 301 from driving the trouser body 3 to fall down after absorbing urine, thereby forming a gap and causing urine to leak sideways. The air storage layer 5 at the corresponding position will be compressed toward the back side of the trouser body 3, and the air in the air storage layer 5 will be discharged through the air outlet pipe 504, thereby achieving ventilation.

[0047] After the urine is absorbed by the super absorbent resin layer 301, the urine will gradually diffuse to the super absorbent resin layer 301 in other parts, thereby causing the salt-sensitive hydrogel 4 in other parts to swell, and gradually squeezed toward the front side of the trouser body 3 to fit the baby, and squeezed toward the back side of the trouser body 3 to gradually compress different air storage layers 5, so that the air storage layers 5 continue to exhaust gas.

[0048] When the baby's gravity presses the air storage layer 5 downward, the air storage layer 5 will be compressed under the action of external force and exhausted through the exhaust pipe 504. When the baby's gravity is transferred, the rubber wrapping layer 501 will drive the air storage layer 5 to return to its original state. While returning to its original state, the capillary 502 will introduce air into the air storage layer 5 from the outside.

[0049] When the newborn's umbilicus has not completely healed, the compression umbilical cover 101 can be stretched outward to maintain a certain space with the umbilicus to form an umbilical protection space for ventilation and to avoid redness, bleeding or infection caused by direct friction between the front waist area of ​​the diaper and the baby's umbilicus.

[0050] When the present invention is used, the magic buckle 2 is adhered to the front waist patch 1 to form a closed system at the front and back waists, thereby completing the wearing process. Before the umbilicus of the newborn is completely healed, the compression umbilical cover 101 can be stretched outward and expanded to maintain a certain space with the umbilicus to facilitate ventilation and avoid redness, bleeding or infection caused by direct friction between the front waist area of ​​the diaper and the baby's umbilicus. When the baby's gravity presses the air storage layer 5 downward, the air storage layer 5 will be compressed under the action of external force to exhaust air through the exhaust pipe 504, so that the inside of the trouser body 3 remains ventilated. When the baby's gravity is transferred, the rubber wrapping layer 501 will drive the air storage layer 5 to return to its original state. While returning to its original state, the capillary 502 will introduce air into the air storage layer 5 from the outside. When urine enters the inside at a certain point on the front of the trouser body 3, it will enter through the highly absorbent resin layer 301. The salt-sensitive hydrogel 4 will swell when encountering the salt in the urine, and the super absorbent resin layer 301 will fit the baby when squeezed toward the front of the trouser body 3 to prevent the super absorbent resin layer 301 from driving the trouser body 3 to fall after absorbing urine, thereby forming a gap and causing urine to leak sideways. The air storage layer 5 at the corresponding position will be compressed when squeezed toward the back of the trouser body 3, and the air in the air storage layer 5 will be discharged through the air outlet pipe 504, thereby achieving breathability. After the urine is absorbed by the super absorbent resin layer 301, the urine will gradually diffuse to the super absorbent resin layer 301 at other positions, thereby causing the salt-sensitive hydrogel 4 at other positions to swell, and gradually squeezed toward the front of the trouser body 3 to fit the baby, and squeezed toward the back of the trouser body 3 to gradually compress different air storage layers 5, thereby allowing the air storage layer 5 to continuously exhaust air.

[0051] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
