Description

Sanitary product with three-dimensional protective enclosure Technical Field

[0001] The present invention relates to the field of disposable sanitary products, in particular to a sanitary product with a three-dimensional protective enclosure. Background Art

[0002] Side leakage is a common problem in sanitary absorbent products used for urinary incontinence or menstrual use. A surge of discharged bodily fluids can temporarily flood the surface of the absorbent product, causing it to leak over the sides. To address this issue, absorbent products employ various methods of providing three-dimensional guards along the lateral edges of the absorbent product to prevent side leakage. However, existing products are ineffective in preventing side leakage during use. Furthermore, the elastic materials, such as the elastic bands, used in the edges of existing three-dimensional guards are relatively rough, rubbing against the wearer's skin and resulting in poor comfort.

[0003] For example, patent application CN201180031683.1 discloses an absorbent article with improved leg cuffs. The absorbent article comprises a topsheet, a backsheet joined to the topsheet, and an absorbent core positioned between the topsheet and the backsheet. The absorbent core may have longitudinal edges and end edges, and the absorbent article may include leg cuffs extending along each longitudinal edge of the absorbent core. The leg cuffs may have a raised position and a flat position, with the cross-sectional area of ​​the leg cuff in the raised position being roughly quadrilateral. Its cross-sectional area is defined by an upper surface, an inner barrier, an outer barrier, and a lower surface. However, this quadrilateral leg cuff design is very wasteful of material. The width of the fabric on both sides is 30% larger than that of conventional three-dimensional cuffs. Furthermore, the quadrilaterals are easily compressed together during use, failing to provide a leak-proof barrier. Furthermore, because the elastic components are located on the upper surface of the leg cuffs, they come into direct contact with the wearer's body, which can still cause discomfort.

[0004] Furthermore, the prior art patent application CN201921488398.2 discloses a nursing pad with a three-dimensional protective structure. The nursing pad includes a nursing pad body and a three-dimensional protective structure. The three-dimensional protective structure includes a non-woven fabric upper layer, a non-woven fabric lower layer, a non-woven fabric left layer, and a non-woven fabric right layer. The non-woven fabric lower layer is parallel to the nursing pad body and is connected to the nursing pad body at the bottom. An elastic layer is provided below the non-woven fabric upper layer, so that the non-woven fabric upper layer, the non-woven fabric lower layer, the non-woven fabric left layer, and the non-woven fabric right layer form a cylindrical shape parallel to the nursing pad body. However, the elastic layer described in the utility model is a stretch fabric with longitudinal elasticity, which is difficult to purchase and has a high degree of technical difficulty. In addition, the three-dimensional protective structure is prone to collapse and has a poor side leakage prevention effect.

[0005] Therefore, the existing anti-side leakage sanitary products mentioned above still have obvious inconveniences and defects in their structure and actual production, and are in urgent need of further improvement. How to create a new sanitary product with a three-dimensional guard, which can form a cylindrical three-dimensional guard by combining elastic bands with water-repellent hot air non-woven fabric and lining cloth, not only improves the wearer's comfort, but also truly prevents side leakage, and is easy to implement and low-cost, has become a goal that the current industry urgently needs to improve.

[0009] As a further improvement, the lining cloth is made of SMS non-woven fabric with a basis weight of 25-40gsm.

[0010] As a further improvement, the length of the lining cloth is equal to the length of the water-repellent hot air non-woven fabric.

[0025] 1 to 4 , the sanitary product with three-dimensional guards in this embodiment includes a long strip-shaped absorbent body 1 , with three-dimensional guards 2 provided on both sides of the absorbent body 1 in the longitudinal direction.

[0026] The absorbent body 1 in this embodiment comprises, from top to bottom, a surface layer 11, a guide layer 12, toilet paper 13, an absorbent layer 14, toilet paper 15, a base film 16, and a release paper 17. The layers are bonded together by adhesive 18 to form an absorbent body with excellent absorption properties. Of course, the absorbent body 1 may also employ other existing structures.

[0027] The three-dimensional guardrail 2 in this embodiment is composed of a water-repellent hot air non-woven fabric 21, an elastic band 22 and a lining cloth 23. The water-repellent hot air non-woven fabric 21 is in the shape of an elongated strip, and the inner side edge of the water-repellent hot air non-woven fabric 21 is bent downward and outward and then pasted on the lower surface of the water-repellent hot air non-woven fabric 21, forming a bending portion with an internal space 24, and the outer bottom surface of the bending portion is pasted to the surface of the absorbent body 1. The outer side edge of the water-repellent hot air non-woven fabric 21 is bonded to the outer edge of the absorbent body 1. The lining cloth 23 is horizontally arranged in the internal space 24 of the bending portion, and the elastic band 22 is pasted between the upper surface of the lining cloth 23 and the corresponding top surface of the internal space 24 of the bending portion by the elastic band glue 25. The lower surface of the lining cloth 23 is separated from the bottom surface of the internal space 24 of the bending portion, and the lining cloth 23 is supported in the internal space 24 of the bending portion by the elastic force of the elastic band 22, forming a cylindrical three-dimensional guardrail, as shown in FIG4. The elastic band 22 is stretched during processing and shrinks naturally, forming a cylindrical support for the bent portion in conjunction with the lining cloth. The cylindrical three-dimensional guard 2 has an arc-shaped outer side and does not have edges that rub against the body, greatly improving comfort.

[0028] In this embodiment, the lining cloth 23 is made of SMS non-woven fabric with a basis weight of 25-40 gsm. The SMS non-woven fabric has a certain degree of stiffness, which can better ensure that the bending portion forms a cylindrical three-dimensional guardrail 2.

[0029] Specifically, the length of the lining fabric 23 is equal to the length of the water-repellent hot air non-woven fabric 21. The length of the elastic band 22 is less than that of the water-repellent hot air non-woven fabric 21, and the elastic band 22 is located in the middle of the water-repellent hot air non-woven fabric 21. That is, the cylindrical three-dimensional guard is high in the middle of the absorbent body 1 and gradually lowers at the two ends of the absorbent body 1, forming a flush bond with the two ends of the absorbent body 1. This conforms to the characteristic of the product being low in the middle and high at the two ends when used by the human body, and has a good side leakage prevention effect.

[0030] In a preferred embodiment, two parallel elastic bands 22 are provided in each of the bent portions. In the adhesive region between the outer bottom surface of the bent portion and the surface of the absorbent body 1, the inner edges of the adhesive regions at the ends of the absorbent body 1 are closer to the center of the absorbent body 1 than the edges of the adhesive regions in the middle of the absorbent body 1. This forms a three-dimensional guardrail 2 that gradually adheres to the absorbent body 1 at the ends, but gradually increases its support in the middle of the absorbent body 1, forming a guardrail structure that meets the requirements of preventing side leakage, is not easy to collapse, and has a good support effect.

[0031] Specifically, the outer bottom surface of the bent portion is adhered to the two end surfaces of the absorbent body 1 by two adhesive strips 3, and the outer bottom surface of the bent portion is adhered to the middle surface of the absorbent body 1 by one adhesive strip 4. Of course, the adhesive strips provided at the two end portions of the bent portion may be widened, while the adhesive strip provided at the middle portion of the bent portion may be narrowed.

[0032] Furthermore, in this embodiment of the sanitary product with three-dimensional guards, an annular groove 5 is formed on the absorbent body 1 between the two three-dimensional guards 2. The annular groove 5 is configured as an asymmetrical structure with a wide front end and a narrow rear end, which better conforms to the human body's physiological structure and facilitates the precise and targeted absorption of body fluids.

[0033] In this embodiment, an elliptical concave channel 6 is pressed into the front end of the annular concave channel 5, and the guide layer 12 is arranged inside the elliptical concave channel 6. The guide layer 12 is a blue core guide layer to improve the guide effect.

[0034] The absorbent body 1 can be a product with wings or without wings, depending on actual needs.

[0035] The sanitary product with three-dimensional guardrails in this embodiment has a novel structural design and is made of readily available materials. It can be processed online on a production line, avoiding the use of elastic fabrics that are difficult to purchase and use. The process is simple and the cost is low.

[0036] The present invention is a sanitary product with a comfortable and elastic three-dimensional guardrail. Since the non-woven fabrics on the inner and outer sides of the three-dimensional guardrail are made of water-repellent hot-air non-woven fabrics, it not only has a water-repellent function, but also is soft and comfortable, and is relatively comfortable when in contact with the human body; the water-repellent hot-air non-woven fabric is bent, and lining cloth and elastic bands are arranged in the bent part, so that the top of the three-dimensional guardrail can be well supported, thereby playing an effective role in leak prevention; and the cylindrical three-dimensional guardrail can effectively relieve skin friction due to the curved outer periphery, making it more comfortable for the wearer to use.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art can make some simple modifications, equivalent changes or modifications based on the technical content disclosed above, which all fall within the scope of protection of the present invention.
