Description

Technical Field

[0001] This utility model relates to the field of children's diaper technology, specifically a children's diaper that prevents navel friction. Background Technology

[0002] Disposable baby diapers are disposable hygiene products designed for infants and young children. They are mainly used to absorb and retain the baby's urine, keeping the baby dry and comfortable. Their main components include super absorbent resin and fluff pulp, which can absorb and lock in a large amount of urine, keeping the baby's skin dry.

[0003] For example, the authorization announcement number "CN212326743U" describes a type of children's diaper. When a person breathes, the elastic components deform, and the state of the pleated support changes, thus altering the size of the cavity and causing airflow within it. However, current children's diapers are folded into small paper packets before use, requiring adults to manually connect the ends and then put them on the child's crotch. Since diapers are generally made of lightweight, highly absorbent cotton, and to maintain elasticity, there are pleats at the edges due to elastic contraction, it's crucial to consider the delicate skin of newborns, especially since the navel is close to internal organs and intestines. The pleats at the edges of the diaper can cause abrasion to the skin around the navel, and existing children's diapers offer relatively poor protection against this abrasion. Utility Model Content

[0004] This invention addresses the problem of poor navel abrasion prevention in existing children's diapers by proposing a children's diaper designed to prevent navel friction.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Preferably, the navel anti-friction structure includes connecting straps and soft strips. The two connecting straps are fixedly connected to both ends of the outer wall of the elastic component. The outer sides of the two connecting straps are fixedly installed with raised fabric. The side walls of the two raised fabrics are fixedly connected with an adhesive layer. The top outer wall of the elastic component is fixedly connected with a buffer layer. The two soft strips are fixedly installed on both sides of the outer wall of the diaper body.

[0008] Preferably, the two ends of the two elastic components are arranged opposite each other, and the two ends of the two flexible strips are fixedly connected to the lower ends of the elastic components.

[0009] Preferably, the anti-leakage absorption structure includes an absorbent layer and anti-leakage strips. The absorbent layer is fixedly installed inside the diaper body, and a skin-friendly layer is fixedly connected to the outer wall surface of the absorbent layer.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figure 1-6 In this embodiment, a baby diaper designed to prevent navel friction includes a diaper body 1, elastic components 2, and ventilation holes 3. Two elastic components 2 are fixedly connected to both ends of the diaper body 1. The two elastic components 2 are elastic waistbands made of polyurethane foam, which mainly serve to make the diaper fit well and improve the leak-proof ability of the waist. When the two elastic components 2 are connected end to end, they can form a waistband that surrounds the child's waist. The outer side of the two elastic components 2 is provided with a navel anti-friction structure 4, and the inside of the diaper body 1 is provided with a side leakage absorption structure 5.

[0023] The navel anti-friction structure 4 includes a connecting strap 41 and a soft strip 45. The two connecting straps 41 are fixedly connected to both ends of the outer wall of the elastic component 2. The connecting straps 41 are made of soft and hygienic pure cotton fabric. Two raised fabrics 42 are sewn out from the outside of the connecting straps 41. The raised fabrics 42 are fixedly installed on the outside of the two connecting straps 41. The raised fabrics 42 are made of a light and soft modal fabric that is skin-friendly and can ensure that they absorb sweat and are not sticky. The side walls of the two raised fabrics 42 are fixedly connected to an adhesive layer 43.

[0024] The adhesive layer 43 is a circular piece of pure cotton fabric sewn onto the inner side of the raised fabric 42. After the diaper body 1 is worn, the adhesive layer 43 will move inward to cover the baby's navel, protecting the delicate and soft navel skin from friction damage. The top outer wall of the elastic component 2 is fixedly connected to the buffer layer 44, which is made of multiple raised soft cotton trims. In this way, the top of the outer wall of the elastic component 2 protrudes from the buffer layer 44. After the child wears the diaper body 1, the buffer layer 44 can surround the top of the elastic component 2 to reduce the discomfort of tightness.

[0025] Two soft strips 45 are fixedly installed on both sides of the outer wall of the diaper body 1. The soft strips 45 are made of abrasion-resistant and smooth fiber material, so that the baby's legs can come into contact with the soft strips 45 after the diaper is worn, and the abrasion of the thigh skin during movement and crawling can be reduced.

[0026] The two ends of the two elastic components 2 are arranged opposite each other, and the two ends of the two flexible strips 45 are fixedly connected to the lower ends of the elastic components 2.

[0027] The connecting strap 41 is made of soft and hygienic pure cotton fabric. Two raised fabrics 42 are sewn out from the outside of the connecting strap 41. The raised fabrics 42 are made of a soft and skin-friendly modal fabric to ensure that they are absorbent and non-sticky. The adhesive layer 43 is a circular pure cotton piece sewn onto the inner side of the raised fabrics 42. After the diaper body 1 is worn, the adhesive layer 43 will move inward to cover the baby's navel, protecting the delicate and soft navel skin from friction damage. In this way, the two extra raised fabrics are used to protect the safety and comfort of the navel area, improving the anti-navel abrasion effect of the children's diaper.

[0028] The anti-leakage absorption structure 5 includes an absorbent layer 51 and anti-leakage strips 52. The absorbent layer 51 is fixedly installed inside the diaper body 1. The absorbent layer 51 is made of a core composed of dust-free paper, non-woven fabric and absorbent resin, which can prevent clumping and make it thinner. A skin-friendly layer 53 is fixedly connected to the outer wall surface of the absorbent layer 51. The skin-friendly layer 53 is made of pure cotton non-woven fabric that fits the delicate skin of children. Two anti-leakage strips 52 are fixedly installed on both sides of the outer wall of the diaper body 1. The anti-leakage strips 52 are cotton strips that protrude from the inner thigh and can prevent urine from leaking and improve the absorbency of the diaper.

[0029] Working principle:

[0030] The baby diaper designed to prevent navel irritation can be stored in a small package when in use. When needed, the package can be opened and the diaper can be taken out. After being opened and folded by an adult or parent, the elastic parts at both ends of the diaper are connected together, forming a pant-like structure with openings on both sides at the bottom for the legs to be put on, and the crotch area in the middle tucking upwards. This makes it easy for the child to wear the diaper to handle urine and keep the lower body dry and comfortable.

[0031] Anti-navel friction protection structure in baby diapers:

[0032] The connecting strap 41 is made of soft and hygienic pure cotton fabric. Two raised fabrics 42 are sewn out from the outside of the connecting strap 41. The raised fabrics 42 are made of a soft and skin-friendly modal fabric to ensure that they absorb sweat and are not sticky. The adhesive layer 43 is a circular pure cotton piece sewn on the inner side of the raised fabrics 42. After the diaper body 1 is worn, the adhesive layer 43 will move inward to cover the baby's navel, protecting the delicate and soft navel skin from friction and damage.

[0033] Anti-abrasion design at the waist and legs of baby diapers to prevent navel chafing:

[0034] The buffer layer 44 is made of multiple raised soft cotton trims. When the child wears the main body 1 of the diaper, the top of the outer wall of the elastic component 2 of the buffer layer 44 can surround the top of the elastic component 2 to reduce the discomfort of tightness. The soft strip 45 is made of abrasion-resistant and smooth fiber material. When the diaper is worn, the infant's legs can come into contact with the soft strip 45, which can reduce the abrasion of the thigh skin during movement and crawling.

[0035] Leak-proof design of baby diapers to prevent navel chafing:

[0036] The absorbent layer 51 is made of a core composed of dust-free paper, non-woven fabric and absorbent resin, which can prevent clumping and make it thinner. The skin-friendly layer 53 is made of pure cotton non-woven fabric that fits the delicate skin of children. Two anti-leakage strips 52 are fixedly installed on both sides of the outer wall of the diaper body 1. The anti-leakage strips 52 are cotton strips that protrude from the inner side of the thighs and can prevent urine from leaking and improve the absorbency of the diaper.

[0037] Example 2:

[0038] Please see Figure 1-6 In this embodiment, a child diaper designed to prevent navel friction includes a top part 2 with two connecting pieces 61 fixedly connected to both sides. The connecting pieces 61 are made of cotton fabric sewn on both sides. The inner wall of the connecting pieces 61 is covered with a liquid adhesive tape with strong adhesive properties. The side walls of the two connecting pieces 61 are fixedly provided with adhesive 62. The adhesive 62 can adhere to the outer wall of the elastic part 2 at the other end to form the basic shape of the diaper. Multiple ventilation holes 3 are fixedly opened inside the elastic part 2. The ventilation holes 3 are small and numerous through holes, which can ensure that the wearing position is breathable and less prone to acne when fitting around the child's waist.

[0039] Working principle:

[0040] The connector 61 is made of cotton fabric sewn on both sides. The inner wall of the connector 61 has a liquid adhesive tape with strong adhesive properties. The adhesive 62 can be attached to the outer wall of the elastic part 2 at the other end to form the basic shape of the diaper. The ventilation holes 3 are small and numerous through holes, which can ensure that the wearing position is breathable and less prone to acne when attached to the waist of the child.
