Technical Field

[0001] The present invention relates to the field of absorbent articles, and particularly to a three-dimensional anti-leakage breast pad. Background Art

[0002] A breast pad is a mother and baby product that prevents the milk of lactating women from overflowing. With the continuous improvement of people's living standards, it has received increasing attention.

[0003] Generally, the breast pad is attached to the breast. Due to the limitation of the absorption rate, when there is an excessive amount of milk overflow, the milk may flow out along the joint surface between the breast pad and the breast, contaminating the user's clothes or causing inconvenience in use. In view of this situation, breast pads with three-dimensional gaskets have been designed, such as the forms shown in documents CN208710268U, CN115944461A, etc. In these existing designs, elastic rubber bands are usually required to be provided on the three-dimensional gasket to achieve the standing effect. However, in these solutions, on the one hand, due to the tightening effect of the elastic rubber band, it usually causes discomfort in use. On the other hand, the use of elastic rubber bands also increases the cost and reduces the production speed. Summary of the Invention

The pair of notch parts are symmetrically arranged along the second center line. At the same time, the concave inner edge includes a point with the maximum distance from the first center line. The point on the concave inner edge with the maximum distance from the first center line is defined as the concave point. A virtual straight line passes through the concave points on a pair of concave inner edges. This virtual straight line divides the folding part into a main barrier area and a skin-friendly area.

[0010] Among them, the main groove section and the side groove section are connected at the concave inner edge.

[0011] Among them, the pressing groove divides the body into an upper area and a lower area. The lower area presents a crescent shape.

[0012] Among them, the body includes an outer edge line, and the side groove section extends to the outer edge line.

Detailed implementation manners

[0017] Please refer to Figures 1 - 4 , an embodiment of the present invention provides a three-dimensional anti-leakage breast pad, so as to enable the anti-leakage partition edge or guardrail of the anti-leakage breast pad to have a stable erected effect without setting elastic rubber bands. At the same time, the three-dimensional anti-leakage breast pad can have higher comfort.

[0018] The three-dimensional anti-leakage breast pad includes a body 10, and the body 10 includes a surface layer 11, an absorbent layer 12 and a bottom layer 13 which are stacked.

[0019] The surface layer 11 is arranged on the side close to the user's skin. Generally, the surface layer 11 is liquid-permeable, so that the milk can be absorbed by the absorbent layer 12 after passing through the surface layer 11. Since the surface layer 11 is in contact with the skin, it is preferably selected to be low-irritant and soft. For example, the unit area weight is 10-60 g / m 2Sheet materials such as gauze, cotton cloth, spunlace non-woven fabric, and hot air non-woven fabric. More preferably, it is a hot air non-woven fabric composed of thermoplastic synthetic fibers. As the synthetic fibers constituting the above-mentioned hot air non-woven fabric, polyolefin fibers such as polyethylene (PE) fibers and polypropylene (PP) fibers, polyester fibers, polyamide fibers such as nylon, etc. can be used. In some alternative embodiments, natural fibers or viscose fibers can also be added simultaneously to further reduce the irritation to the skin. These natural fibers can include wood fibers, cotton fibers, etc.

[0020] The absorption layer 12 is used to absorb the lotion and is stacked below the surface layer 11. More specifically, the absorption layer 12 is disposed between the surface layer 11 and the bottom layer 13. The absorption layer 12 is formed by tangling a number of fibers and is appropriately connected to form a three-dimensional network structure. There are a number of pores distributed among the three-dimensional network structure, and the lotion diffuses and is accommodated through these pores. More specifically, the fibers can be plant fibers or synthetic fibers, and the plant fibers can be fluff pulp fibers, etc.

[0021] The bottom layer 13 is used to prevent liquid penetration and is configured on the side away from the user's skin. The bottom layer 13 is usually a water-repellent material. Specifically, it can be a PE film, SMS non-woven fabric, etc. Preferably, the bottom layer 13 can allow gases, such as water vapor, to pass through while liquids cannot pass through, so that it will not be stuffy during use.

[0022] The body 10 includes a length direction and a width direction. The body 10 includes a main absorption area 101 and side areas 102 located on both sides of the main absorption area 101. In this embodiment, the side areas 102 are arranged along the width direction of the body 10. The main absorption area 101 includes a central absorption area 1010, and the central absorption area 1010 is configured to correspond to the body fluid leakage area. Specifically in this embodiment, the central absorption area 1010 corresponds to the nipple. At the same time, the body 10 also includes an outer peripheral edge portion 1012. The surface layer 11 and the bottom layer 13 are joined along the outer peripheral edge portion 1012, and through the joining at the outer peripheral edge portion 1012, a closed space is formed between the surface layer 11 and the bottom layer 13, and the absorption layer 12 is accommodated in this closed space.

[0023] The joining means that the joined surface layer 11 and bottom layer 13 are connected to form an integral body. Generally, it can be formed by hot melting or bonding. Among them, hot melting can be achieved by heating the material itself to reach the melting point temperature, then locally melting and solidifying to form a connection, or by applying external energy such as ultrasonic waves to the material to cause local high-temperature melting and solidifying to form a connection. The bonding can be achieved by setting an adhesive between the surface layer 11 and the bottom layer 13, and the surface layer 11 and the bottom layer 13 are fixedly connected through the adhesive.

[0024] A guardrail 20 is provided in each side area 102, and the guardrail 20 includes an opening end 201 and a connecting end 202. The guardrail 20 is separated from the surface layer 11 at the opening end 201 so that the guardrail 20 can form a standing effect along the opening end 201. The connecting end 202 is configured to be connected to the surface layer 11, and the connecting end 202 is in a shape protruding outward, and the outward refers to the direction away from the central absorption area 1010. In this embodiment, the connecting end 202 is in an arc shape, and makes the guardrail 20 in a pocket shape.

[0025] It can be understood that the guardrail 20 can be made of water-repellent material, such as water-repellent non-woven fabric, PE, or SMS non-woven fabric.

[0026] The main body 10 also includes a groove 111 protruding toward the outside of the main body 10, the groove 111 includes a main groove section 1111 located at the surface layer 11 and a side groove section 1112 located at the enclosure 20, the opening end 201 includes an opening edge line 2010, the main groove section 1111 and the side groove section 1112 both extend to the opening edge line 2010 and connect at the opening edge line 2010. Through the above arrangement, it can be seen that the groove 111 The main body 10 is divided into an upper area and a lower area 1011, and the groove 111 is recessed from the surface layer 11 to the absorbent layer 12, so that the lower area 1011 will bend or bend upward along the groove 111, and at the same time, a triangular area 2227 is formed with the opening edge line 2010 at the lower side of the side groove section 1112. When the lower area 1011 is bent or bent upward, the opening edge line 2010 is squeezed toward the middle by force, so that the pocket-shaped guard 20 is formed into a standing state. On the second hand, the triangular area 2227 is kept in a state of being attached to the surface layer 11 or bent toward the surface layer 11, and the triangular area 2227 and the guardrail 20 connected to the triangular area 2227 form a supporting effect, so that the upright guardrail 20 is maintained in a three-dimensional shape. On the third hand, the guardrail 20 forms an upright shape on both sides. At the same time, the lower area 1011 is bent upward so that the entire three-dimensional breast pad forms a hemispherical three-dimensional shape, which can better adapt to and cover the breast. On the fourth hand, the pressing groove 111 is arranged horizontally as a whole and is located on the lower side of the main body 10. When lotion overflows during use, the pressing groove 111 can diffuse and block the lotion in the horizontal direction, further reducing the risk of lotion overflow or contamination of clothes. In practice, in a comparative test with the structure shown in CN208710268U, the discomfort (squeezing, squeezing) of use is reduced by an average of 75%, and compared with conventional round sheet breast pads, the lotion leakage is reduced by an average of 60%.

[0027] Further, the guard 20 is connected to the surface layer 11 in a folded form. Specifically, the guard 20 includes a connecting portion 21 and a folding portion 22. Among them, the connecting portion 21 forms the connecting end 202, and the folding portion 22 is used to form the erected guard 20 to block body fluids. The connecting portion 21 includes a first surface 211 and is connected to the surface layer 11 in a form that combines through the first surface 211. The folding portion 22 is folded from the connecting portion 21 toward the surface layer 11 along a fold line, and one end thereof facing the central absorption area 1010 is separated from the surface layer 11 to form an open end 201.

[0028] Further, the connecting portion 21 and the folding portion 22 are integrally formed. After folding, the first surface 211 is located on the side of the folding portion 22 away from the surface layer 11.

[0029] Further, the folding portion 22 further includes an indentation line 223. The indentation line 223 divides the folding portion 22 into an attached area 221 and an upright area 222. When the erected guard is formed, the upright area 222 stands up, and the attached area 221 remains attached to the surface layer 11. It can be understood that the indentation line 223 is an indentation recessed from the first surface 211 toward the surface layer 11. In this case, when the indentation line 223 is provided, the upright area 222 is easily bent and erected along the indentation line 223 under its own stress.

[0030] Further, the folding portion 22 further includes a pair of notch portions 2223. The notch portions 2223 include concave inner edges 2224 recessed toward the connecting portion 21. Define a first center line parallel to the length direction of the body 10 and a second center line parallel to the width direction of the body 10. The pair of notch portions 2223 are symmetrically arranged along the second center line. At the same time, the concave inner edge 2224 includes a point with the maximum distance from the first center line. The point on the concave inner edge 2224 with the maximum distance from the first center line is the concave point 2225. A virtual straight line 2226 passes through the concave points 2225 on the pair of concave inner edges 2224. The virtual straight line 2226 divides the folding portion 22 into a main blocking area 2221 and a skin-attaching area 2222. The opening edge line 2010 of the skin-attaching area 2222 is a wavy line. It can be understood that after standing up, the area of the skin-attaching area 2222 forms a fit with the skin. Setting the opening edge line 2010 of the skin-attaching area 2222 as a wavy line makes the edge of the skin-attaching area in a wrinkled shape, thus forming a better touch.

[0031] Further, the opening edge line 2010 of the skin-attaching area 2222 is in a form protruding toward the central absorption area 1010.

[0032] Further, the distance between a pair of concave points 2225 is 60%-80% of the width of the open end 201, so that the skin-contact area 2222 has sufficient width to form a better touch feeling.

[0033] In addition, the pressing groove 111 is a pressing groove 111 protruding in the outer direction, so that the pressing groove 111 presents a tongue-shaped form extending downward.

[0034] Further, the lower area 1011 located below the pressing groove 111 presents a crescent shape.

[0035] Further, the main groove section 1111 and the side groove section 1112 are integrally formed.

[0036] Further, the main groove section 1111 and the side groove section 1112 are connected at the concave inner edge line 2224.

[0037] Further, the body 10 includes an outer edge line 1013, and the side groove section 1112 extends to the outer edge line 1013.

[0038] Further, the surface layer 11 includes a lower groove section corresponding to the side groove section 1112.

[0039] Please refer to Figures 4 - 12 , in Figures 4 - 12 shows the process of preparing the three-dimensional anti-spill breast pad. Specifically, the process includes: S10: Provide a surrounding sheet 200 and form a surrounding 20 with an opening edge line 2010.

[0040] Specifically, the surrounding 20 can be formed by laying the surrounding sheet 200 and cutting off the surplus material of the surrounding sheet 200 through a surrounding 20 cutter. In a specific embodiment, the surrounding 20 cutter can be an S cutter. The single surrounding sheet 200 is cut by the S cutter to form complementary S-shaped opening edge lines 2010, and the complementary surrounding 20 with S-shaped edge lines is separated after the S-shaped opening edge lines 2010 are formed.

[0041] It can be understood that a pair of surrounding 20 cutters can also be set to cut the corresponding surrounding sheets 200 respectively to form opening edge lines 2010 corresponding to the shape of the surrounding 20 cutter.

[0042] S20: Provide the surface layer 11 and combine the surrounding 20 with the surface layer 11.

[0043] Please refer to Figure 5 and Figure 6 , in Figure 6 shows the cross-sectional view taken along line B-B in Figure 5 The combination of the surrounding 20 and the surface layer 11 can be carried out in the following manner: S21: After laying the surface layer 11; S22: Stack the enclosure 20 formed by S10 on the upper side of the surface layer 11. It can be understood that the opening side line 2010 is located on the outer side, and the outer side refers to the side away from the surface layer 11.

[0044] S23: Combine the enclosure 20 with the surface layer 11. It can be understood that the enclosure 20 and the surface layer 11 can be combined by adhesion or heat melting, and the area combined with the surface layer 11 forms a connection part 21.

[0045] S30: Fold the enclosure 20 to form a combined body.

[0046] By folding the enclosure 20, a folding part 22 is formed, and after folding, an opening end 201 facing the central absorption area 1010 is formed.

[0047] S40: Provide the bottom layer 13 and the absorption layer 12, and stack the combined body, the absorption layer 12 and the bottom layer 13 to form the main body.

[0048] It can be understood that the bottom layer 13, the absorption layer 12 and the combined body can be laid in sequence, and an adhesive is also provided on the bottom layer 13 and / or the surface layer 11, so that the surface layer 11 and the bottom layer 13 are combined to form a peripheral edge part 1012.

[0049] It can be understood that pressure can be applied at the position corresponding to the peripheral edge part 1012 by a peripheral sealing roller. While performing peripheral sealing by the peripheral sealing roller, an indentation line 223 is formed on the upper side of the folding part 22, so as to form an attachment area 221 and an upright area 222. At the same time, through the pressure applied by the peripheral sealing roller, when the enclosure 20 stands up, it maintains an attached state, so that the upright area 222 can stand up easily.
