DETAILED DESCRIPTION

[0035] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0036] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connected" and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0037] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature.

[0038] Disposable nursing pads are mainly used to prevent milk leakage, thus keeping the skin around the breasts clean and hygienic. Disposable nursing pads bring convenience to both working mothers and mothers who take care of their babies at home.

[0039] In some cases, users may still experience dampness and stuffiness when using nursing pads in the related art. For example, if a user squeezes the nursing pad during use, the liquid absorbed by the absorbent material may seep out from the bottom layer of the nursing pad and soak clothing. The clothing, soaked with breast milk, not only causes embarrassment and inconvenience, but also causes dampness and stuffiness.

[0040] In order to solve the problem of the discomfort of feeling damp when using a nursing pad in the related art, the present application provides a nursing pad with a bottom layer having good liquid-isolating properties. The liquid in the absorption layer is not easy to seep out from the bottom layer, which is conducive to keeping dryness. In addition, the nursing pad has good air permeability, which is conducive to avoiding or reducing the feeling of stuffiness.

[0041] Disposable nursing pads are mainly used to prevent milk leakage, thus keeping the skin around the breasts clean and hygienic. Disposable nursing pads bring convenience to both working mothers and mothers who take care of their babies at home.

[0042] In some cases, users may still experience dampness and stuffiness when using nursing pads in the related art. For example, if a user squeezes the nursing pad during use, the liquid absorbed by the absorbent material may easily seep out of the bottom layer 30 of the nursing pad and soak the clothing. The clothing, soaked with breast milk, not only causes embarrassment and inconvenience, but also causes dampness and stuffiness.

[0043] In order to solve the problem of the discomfort of feeling damp when using a nursing pad in the related art, the present application provides a nursing pad with a bottom layer having good liquid-isolating properties. The liquid absorbed in the absorption layer is not easy to seep out from the bottom layer, which is conducive to keeping dryness. In addition, the nursing pad has good air permeability, which is conducive to avoiding or reducing the feeling of stuffiness.

[0044] Please refer to Figures 1 to 9 , the following is an explanation of nursing pads.

[0045] Reference Figure 1 、 Figure 2 、 Figure 4 The breast pad includes a surface layer 10, an absorption layer 20 and a bottom layer 30. The absorption layer 20 is sandwiched between the surface layer 10 and the bottom layer 30, and the absorption layer 20 is fixed between the surface layer 10 and the bottom layer 30.

[0046] When using the nursing pad, the nursing pad is placed between the breast and clothing, for example, between the breast and underwear (bra), or the user can directly attach the nursing pad between the bra and home clothes without wearing underwear. When using the nursing pad, the surface layer 10 is located on the side of the absorbent layer 20 close to the breast, and the bottom layer 30 is located on the side of the absorbent layer 20 away from the breast.

[0047] The surface layer 10 is a hydrophilic layer, and the material of the surface layer 10 can be, but is not limited to, one or more of hot air non-woven fabrics and cotton fibers. For example, the surface layer 10 is a hot air non-woven fabric layer. When the surface layer 10 includes fibers (such as cotton fibers), the fibers in the surface layer 10 have a fineness of 0.6D-12D; the hydrophilic fibers are composed of fine denier fibers and or non-fine denier fibers, the fine denier fibers are fibers with a fineness of 0.3D-1.8D, and the non-fine denier fibers are fibers with a fineness of 2.0D-12.0D. The fine denier fibers and non-fine denier fibers in the hydrophilic fibers are composed of a single component or multiple components; the single component is a single-component hydrophilic fiber composed of fine denier fibers or non-fine denier fibers, and the multi-component is a multi-component hydrophilic fiber composed of fine denier fibers and non-fine denier fibers by mixing, multi-layer combing, etc.

[0048] The absorbent layer 20 is used to absorb and lock in liquid. The absorbent layer 20 may include, but is not limited to, a polymer absorbent resin. When an infant sucks on the mother's nipple, breast milk is stimulated to flow out. However, milk may also flow out of the nipple even when the infant or the breast pump is not sucking on the mother's nipple. The use of a breast pad with a breast shield can utilize the absorbent layer 20 to absorb and lock in the milk, preventing it from leaking out and soaking clothing. This also helps maintain the comfort and hygiene of the mother's breast skin.

[0049] The bottom layer 30 is located on the side of the absorbent layer 20 away from the breast, and the bottom layer 30 can be separated between the breast and the clothing. The bottom layer 30 includes at least two liquid-blocking layers. Figure 2 、 Figure 3 、 Figure 6 As shown, the bottom layer 30 includes a first liquid-blocking layer 31 and a second liquid-blocking layer 32. The first liquid-blocking layer 31 is positioned between the absorbent layer 20 and the second liquid-blocking layer 32. Both the first liquid-blocking layer 31 and the second liquid-blocking layer 32 are made of a highly breathable material and serve to prevent liquid from flowing from the absorbent layer 20 away from the surface layer 10. The first liquid-blocking layer 31 is a preliminary barrier layer, providing a preliminary barrier to liquid and preventing it from flowing toward the outer surface of the bottom layer 30. The second liquid-blocking layer 32 is a liquid-blocking layer of the bottom layer 30, preventing liquid from seeping out of the bottom layer 30.

[0050] Optionally, between two adjacent liquid-blocking layers in the bottom layer 30 , the liquid-blocking layer on the side facing away from the absorbent layer 20 has a liquid-blocking capability equal to or stronger than that of the liquid-blocking layer on the side close to the absorbent layer 20 .

[0051] It is understandable that in other embodiments, the number of liquid-blocking layers in the bottom layer 30 may also be three, four, or the like.

[0052] The nursing pad of the present application meets the requirements of breathability while preventing or reducing breast milk from leaking out of the bottom layer 30. This reduces the risk of liquid seeping out of the bottom layer 30 and soaking clothing, keeping clothing dry. It is understood that because the bottom layer 30 comprises at least two liquid-blocking layers, even if the nursing pad is squeezed during use, breast milk trapped in the absorbent layer 20 is unlikely to completely penetrate the bottom layer 30. During use, the nursing pad's breathability and the bottom layer's impermeability address the issues of airtightness and dampness during wear, reducing discomfort and avoiding dampness and stuffiness.

[0053] In one embodiment, the first liquid-blocking layer 31 is a non-woven fabric including a meltblown layer, and the second liquid-blocking layer 32 is a non-woven fabric including a meltblown layer. The meltblown layer refers to a meltblown layer. The fibers in the meltblown layer are relatively fine, and the specific surface area of ​​these fibers is much larger than that of ordinary fibers, thus effectively blocking liquid penetration. Both the first liquid-blocking layer 31 and the second liquid-blocking layer 32 in the bottom layer 30 include at least a meltblown layer. The meltblown layer has excellent air permeability and liquid barrier properties, which can prevent both stuffiness and dampness. Compared to breast pads with a PE breathable film or other structures as the bottom layer 30, the breast pad of this embodiment has two layers of meltblown non-woven fabric in the bottom layer 30, balancing air permeability and preventing liquid from seeping out of the bottom layer 30. Even in hot summer days or when wearing too many clothes, the breast pad of this embodiment can provide a dry and comfortable breast experience.

[0054] Optionally, the first liquid-blocking layer 31 is a composite high-barrier nonwoven fabric comprising a spunbond nonwoven fabric and a meltblown nonwoven fabric, and the second liquid-blocking layer 32 is a composite high-barrier nonwoven fabric comprising a spunbond nonwoven fabric and a meltblown nonwoven fabric. The first liquid-blocking layer 31 and / or the second liquid-blocking layer 32 are configured to include at least one layer of spunbond nonwoven fabric and at least one layer of meltblown nonwoven fabric, the two layers of nonwoven fabric being bonded together.

[0055] Illustratively, the first liquid-resistant layer 31 is a multi-layered first composite non-woven fabric, and a spunbond layer is provided on both the side of the meltblown layer of the first liquid-resistant layer 31 close to the absorbent layer 20 and the side away from the absorbent layer 20. The second liquid-resistant layer 32 is a multi-layered second composite non-woven fabric, and a spunbond layer is provided on both the side of the meltblown layer of the second liquid layer close to the absorbent layer 20 and the side away from the absorbent layer 20.

[0056] Among them, the spunbond layer refers to the Spunbond Layer. The spunbond layer has excellent physical properties, such as high strength and stability. It can provide structural support for the first composite non-woven fabric and the second composite non-woven fabric to prevent them from deformation or damage during use. The spunbond layer can protect the meltblown layer of the inner layer. Although the meltblown layer has good liquid barrier properties, its strength is relatively low and it is easily mechanically damaged. The presence of the spunbond layer can effectively prevent the meltblown layer from being worn or damaged during use. The combination of the spunbond layer and the meltblown layer allows the first liquid barrier layer and the second liquid barrier layer to have good air permeability, liquid barrier and anti-seepage properties, and stability, so that during the wearing and use of the anti-breast leakage pad, even if the bottom layer 30 produces friction with the surrounding area, it can still maintain stable performance.

[0057] Optionally, the liquid-resistant performance of the second liquid-resistant layer 32 is stronger than that of the first liquid-resistant layer 31. For example, the number of melt-blown layers in the second liquid-resistant layer 32 is greater than the number of melt-blown layers in the first liquid-resistant layer 31, or the thickness of the melt-blown layer in the second liquid-resistant layer 32 is greater than the thickness of the melt-blown layer in the first liquid-resistant layer 31, and so on.

[0058] Optionally, the grammage per unit area of ​​the second liquid-resistant layer 32 is greater than the grammage per unit area of ​​the first liquid-resistant layer 31 .

[0059] In one embodiment, the first liquid-blocking layer 31 has a grammage per unit area of ​​8g-15g, and is used to initially prevent liquid penetration; the second liquid-blocking layer 32 has a grammage per unit area of ​​15g-100g, and is used to prevent liquid from penetrating the bottom layer 30, thereby preventing the liquid from overflowing the bottom layer 30.

[0060] In one embodiment, the first liquid-blocking layer 31 is an SMS non-woven fabric, and the second liquid-blocking layer 32 is one of an SMMS non-woven fabric, an SMMMS non-woven fabric, an SMMMMS non-woven fabric, and an SSMMMS non-woven fabric. In other embodiments, the first liquid-blocking layer 31 is an SMMS non-woven fabric, and the second liquid-blocking layer 32 is one of an SMMMS non-woven fabric, an SMMMMS non-woven fabric, and an SSMMMS non-woven fabric.

[0061] By providing two or more meltblown layers in the second liquid-blocking layer 32, liquid can be effectively prevented from penetrating and seeping out of the bottom layer 30 to soak the clothes, ensuring dryness. The first liquid-blocking layer 31 has fewer meltblown layers than the second liquid-blocking layer 32, thus providing a preliminary barrier effect.

[0062] SMS nonwoven fabric, short for Spunbond-Meltblown-Spunbond, is a composite of three layers: spunbond (S), meltblown (M), and spunbond (S). The spunbond layer provides strength and stability, while the meltblown layer, with its fine fiber structure, offers high barrier properties. SMS nonwoven fabric is breathable, soft, and has excellent barrier properties.

[0063] SMMS nonwoven fabric adds a meltblown layer to SMS, creating a four-layer structure: spunbond-meltblown-meltblown-spunbond. This structure further enhances the barrier properties and functionality of the nonwoven. In addition to the advantages of SMS, it also offers higher barrier efficiency, stronger resistance to liquid penetration, and improved comfort.

[0064] SMMMS non-woven fabric adds two meltblown layers on the basis of SMS, forming a five-layer composite structure, namely spunbond-meltblown-meltblown-meltblown-spunbond, which has better barrier properties.

[0065] SMMMMS non-woven fabric adds three meltblown layers on the basis of SMS, forming a six-layer composite structure, namely spunbond-meltblown-meltblown-meltblown-meltblown-spunbond, which has extremely high barrier efficiency, super strong resistance to liquid penetration, good breathability and comfort.

[0066] SSMMMS non-woven fabric represents a six-layer composite non-woven fabric structure of spunbond-spunbond-meltblown-meltblown-meltblown-spunbond, which has higher barrier efficiency and strength.

[0067] For example, the bottom layer 30 is composed of a first liquid-blocking layer 31 and a second liquid-blocking layer 32. The first liquid-blocking layer 31 primarily provides a preliminary barrier to liquids and can be made of a high-barrier composite nonwoven fabric, such as SMS or SMMS, with a unit weight of 8g-15g. The second liquid-blocking layer 32 primarily prevents liquids from escaping the bottom layer 30, and therefore is made of a high-barrier composite nonwoven fabric, such as SMMMMS or SSMMMS, with a unit weight of 15g-100g. This structural design of the bottom layer 30 improves the pad's impermeability and maximizes its breathability.

[0068] In one embodiment, to improve breathability and impermeability, the bottom layer 30 further includes a mesh layer (not shown). The mesh layer is fixed to the side of the second liquid-blocking layer 32 facing away from the first liquid-blocking layer 31 and has a plurality of breathable holes. When the breast pad is in use, the mesh layer is separated between the second liquid-blocking layer 32 and the clothing. This creates a certain gap between the second liquid-blocking layer 32 and the clothing, which helps to improve breathability. In other embodiments, the mesh layer may not be provided in the bottom layer 30.

[0069] In addition to the structural design of the bottom layer 30 of the breast pad in any of the aforementioned embodiments, in some embodiments of the present application, the anti-leakage performance of the breast pad is enhanced by the design of a hydrophobic layer. A first hydrophobic layer is disposed between the bottom layer 30 and the absorbent layer 20, and / or a second hydrophobic layer is disposed between adjacent liquid-blocking layers within the bottom layer 30.

[0070] Optionally, the bottom layer 30 includes at least a first liquid-blocking layer 31 and a second liquid-blocking layer 32, wherein the first liquid-blocking layer 31 is located between the absorbent layer 20 and the second liquid-blocking layer 32. In this case, a first hydrophobic layer 41 is disposed between the absorbent layer 20 and the first liquid-blocking layer 31, and / or a second hydrophobic layer 42 is disposed between the first liquid-blocking layer 31 and the second liquid-blocking layer 32. Figure 3 It is shown that the first hydrophobic layer 41 is provided only between the absorption layer 20 and the first liquid-blocking layer 31 . Figure 7 It is shown that a first hydrophobic layer 41 is provided between the absorption layer 20 and the first liquid-blocking layer 31 , and a second hydrophobic layer 42 is provided between the first liquid-blocking layer 31 and the second liquid-blocking layer 32 .

[0071] The first hydrophobic layer 41 is used to prevent liquid from penetrating from the absorbent layer 20 into the first liquid-blocking layer 31. The second hydrophobic layer 42 is used to prevent liquid from penetrating from the first liquid-blocking layer 31 into the second liquid-blocking layer 32. Both the first hydrophobic layer 41 and the second hydrophobic layer 42 prevent liquid from penetrating from the absorbent layer 20 into the base layer 30, thereby reducing the risk of liquid penetrating from the back of the nursing pad and overflowing from the base layer 30, helping to keep the wearer's chest dry and locking liquid in the absorbent layer 20.

[0072] When the first hydrophobic layer 41 is disposed between the absorbent layer 20 and the first liquid-blocking layer 31, the first hydrophobic layer 41 can be provided in any of the following ways: the first hydrophobic layer 41 is a hydrophobic oil agent coated on the side of the absorbent layer 20 proximate to the first liquid-blocking layer 31; and / or the first hydrophobic layer 41 is a hydrophobic oil agent coated on the side of the first liquid-blocking layer 31 proximate to the absorbent layer 20. In other words, the surface of the absorbent layer 20 proximate to the first liquid-blocking layer 31 is covered with the first hydrophobic layer 41, and / or the surface of the first liquid-blocking layer 31 proximate to the absorbent layer 20 is covered with the first hydrophobic layer 41.

[0073] When the second hydrophobic layer 42 is disposed between the first liquid-blocking layer 31 and the second liquid-blocking layer 32, the first hydrophobic layer 41 can be provided in any of the following ways: the second hydrophobic layer 42 is a hydrophobic oil agent coated on the side of the first liquid-blocking layer 31 closest to the second liquid-blocking layer 32; and / or the second hydrophobic layer 42 is a hydrophobic oil agent coated on the side of the second liquid-blocking layer 32 closest to the first liquid-blocking layer 31. In other words, the surface of the first liquid-blocking layer 31 closest to the second liquid-blocking layer 32 is covered with the second hydrophobic layer 42, and / or the surface of the second liquid-blocking layer 32 closest to the first liquid-blocking layer 31 is covered with the second hydrophobic layer 42.

[0074] The provision of the first hydrophobic layer 41 adds a barrier to prevent liquid from penetrating into the first liquid-blocking layer 31 .

[0075] The provision of the second hydrophobic layer 42 adds a barrier to prevent liquid from penetrating into the second liquid-resistant layer 32 .

[0076] It is understood that the two liquid-blocking layers have a certain degree of water-blocking performance, but in certain circumstances (such as due to wear, aging, etc.), the liquid-blocking performance of the first liquid-blocking layer 31 may be reduced. The first hydrophobic layer 41 and / or the second hydrophobic layer 42 can provide additional water-blocking protection, greatly reducing the risk of liquid penetrating the exterior of the product. In this way, when a mother wears a nursing pad between her breasts and clothing and presses on the nursing pad (such as when holding a baby, squeezing the nursing pad, or when the baby's hands touch and press the nursing pad during movement), the nursing pad can also effectively lock in liquid, preventing liquid from being squeezed out of the absorbent layer 20 and seeping out of the bottom layer 30, keeping the mother dry.

[0077] It can be understood that when the second hydrophobic layer 42 is included, the first liquid-blocking layer 31 and the second liquid-blocking layer 32 provided in the bottom layer 30 of the anti-breast leakage pad can not only play the role of preliminary blocking liquid seepage and strengthening the role of blocking liquid seepage through the two liquid-blocking layers, but also provide a surface between the two liquid-blocking layers to facilitate the coating of the hydrophobic oil agent to form the second hydrophobic layer 42.

[0078] Of course, in other embodiments, the first hydrophobic layer 41 and the second hydrophobic layer 42 may not be provided.

[0079] In one embodiment, referring to Figure 7 A first hydrophobic layer 41 is disposed between the absorbent layer 20 and the first liquid-blocking layer 31, and a second hydrophobic layer 42 is disposed between the first liquid-blocking layer 31 and the second liquid-blocking layer 32. The surface layer 10, absorbent layer 20, and base layer 30 are stacked along the z-direction, with the z-projected area of ​​the first bundle of first hydrophobic layer 41 and the z-projected area of ​​the second hydrophobic layer 42 at least partially offset. This arrangement not only enhances the water-blocking properties of the hydrophobic layer, effectively preventing liquid from penetrating the second liquid-blocking layer 32, but also maintains air permeability from the absorbent layer 20 to the outer surface of the base layer 30.

[0080] For example, referring to Figure 7 The surface of the absorbent layer 20 facing away from the top layer 10 is a first surface. A portion of the first surface is a first clean area, and a portion of the first area is covered with the first hydrophobic layer 41. The surface of the first liquid-blocking layer 31 facing away from the absorbent layer 20 is a second surface. A portion of the second surface is a second clean area, and a portion of the second clean area is not covered with the second hydrophobic layer 42. The first clean area and the second clean area are not coated with a hydrophobic oil. In the stacking direction of the top layer 10, the absorbent layer 20, and the bottom layer 30, the first hydrophobic layer 41 is aligned with the second clean area, and the first clean area is aligned with the second hydrophobic layer 42.

[0081] In the space between the absorption layer 20 and the second liquid-blocking layer 32 , a first hydrophobic layer 41 is arranged in part of the area, and a second hydrophobic layer 42 is arranged in part of the area. Liquid in the absorption layer 20 that flows toward the second liquid-blocking layer 32 will be blocked by the first hydrophobic layer 41 or the second hydrophobic layer 42 .

The absorbent core 22 is secured between the first covering layer 21 and the first liquid-blocking layer 31. The edges of the first covering layer 21 are secured to the edges of the first liquid-blocking layer 31 to secure the absorbent core 22 within.

[0091] Optionally, the surface layer 10, the absorption layer 20 and the bottom layer 30 are bonded and fixed by heat pressing or ultrasound.

[0092] Optionally, the first liquid-resistant layer 31 and the second protective layer in the adsorption layer are combined and fixed by heat pressing or ultrasonic waves.

[0093] Optionally, the first liquid-resistant layer 31 and the second liquid-resistant layer 32 are bonded and fixed by heat pressing or ultrasonic waves.

[0094] In one embodiment, the breast pad has multiple heat embossing patterns, where the surface layer 10, the absorbent layer 20, and the bottom layer 30 are combined and fixed.
