Description

Technical Field

[0001] The present invention relates to the field of absorbent articles, and particularly to an adaptive direct - sticking breast pad. Background Art

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

[0003] For convenient use, an adhesive for fixing the breast pad to the inner garment is usually provided on the side of the breast pad facing the inner garment. At the same time, in order to adapt to the shape of the breast, such as a spherical or arched shape, these adhesives can only be set in a relatively small area. However, with this fixing form, it is often difficult to form a relatively stable fixation and difficult to maintain the fit with the breast. Especially at night or when exercising, it is easy for the breast pad to separate from the breast, resulting in the milk not being absorbed by the breast pad and causing discomfort in use.

[0004] There is literature, such as CN209332487U, which proposes to set strip - shaped hydrogels on the surface layer to achieve better attachment and leakage prevention. That is, this product form is a direct - sticking form. However, in practice, it is found that on the one hand, it is difficult to stably maintain the attachment to the breast, and on the other hand, it is difficult to adapt to breasts of different sizes, with poor adaptability. Therefore, a new technical solution is needed to solve the above technical problems. Summary of the Invention

Specific implementation manners

[0019] Please refer to Figures 1 - 4 The breast pad provided by the first embodiment of the present application includes a body 10, the body 10 includes a main body part 11, and the main body part 11 includes a surface layer 111, an absorbent layer 112, and a bottom layer 113 which are stacked.

[0020] The surface layer 111 is arranged on the side close to the user's skin. Generally, the surface layer 111 is liquid-permeable so that the lotion can be absorbed by the absorbent layer 112 after passing through the surface layer 111. Since the surface layer 111 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.

[0021] The absorption layer 112 is used to absorb the lotion and is stacked below the surface layer 111. More specifically, the absorption layer 112 is disposed between the surface layer 111 and the bottom layer 113. The absorption layer 112 is formed by proper connection of several fibers entangled to form a three-dimensional network structure. There are several pores distributed among the three-dimensional network structures, through which the lotion diffuses and is accommodated. More specifically, the fibers can be plant fibers or synthetic fibers, and the plant fibers can be fluff pulp fibers, etc.

[0022] The bottom layer 113 is used to prevent liquid penetration and is disposed on the side away from the user's skin. The bottom layer 113 is usually a water-repellent material. Specifically, it can be a PE film, SMS non-woven fabric, etc. Preferably, the bottom layer 113 can allow gases, such as water vapor, to pass through while liquids cannot pass through, so that it will not be stuffy during use.

[0023] The main body 11 includes an absorption area for absorbing the lotion. It can be understood that the absorption area is correspondingly arranged with the absorption layer 112. At the same time, the main body 11 also includes an outer peripheral edge portion 116 surrounding the periphery of the absorption area. The surface layer 111 and the bottom layer 113 are joined along the outer peripheral edge portion 116, and through the joining at the outer peripheral edge portion 116, a closed space is formed between the surface layer 111 and the bottom layer 113, and the absorption layer 112 is accommodated in this closed space. It can be understood that the surface layer 111 and the bottom layer 113 can also be joined along the outer peripheral edge portion 116 into other shapes, such as rectangles, rounded rectangles, ellipses, etc., which will not be elaborated here.

[0024] The joining means that the joined surface layer 111 and bottom layer 113 are connected to form a whole. Generally, it can be formed by hot melting or bonding. Among them, hot melting can be achieved by heating the material itself to reach its 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 make the material locally generate high temperature melting and solidifying to form a connection. The bonding can be achieved by setting an adhesive between the surface layer 111 and the bottom layer 113, and making the surface layer 111 and the bottom layer 113 form a fixed connection through the adhesive.

[0025] The described body 10 further includes wing portions 12 extending outward from the body portion 11. The wing portions 12 include an adjustment area 121 and an attachment area 122 located outside the adjustment area 121. The outside here refers to the side away from the body portion 11. At the same time, a direct attachment adhesive layer 13 is provided on the attachment area 122. The direct attachment adhesive layer 13 includes an adhesive, and the adhesive can be a natural or synthetic adhesive material. Specifically, it can include adhesives such as starch, polyurethane, nitrocellulose, polyvinyl acetate, etc.; water-soluble adhesives such as ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, etc.; emulsion adhesives such as vinyl acetate resin, acrylic resin, etc.; hot-melt adhesives composed of thermoplastic resins such as polystyrene, polyurethane, polyacrylate, etc. Further, it can be hot-melt glue, gel-type adhesive, etc. Of course, it is not limited to hot-melt glue or gel-type adhesive.

[0026] Further, the adhesive used as the direct attachment adhesive layer 13 can be a pressure-sensitive adhesive or a hydrogel. Typical pressure-sensitive adhesives such as DRUO-TAK 8F171C, HL2816, MH205, HL1439, etc. can be used as the adhesive of the direct attachment adhesive layer 13.

[0027] It can be understood that the direct attachment adhesive layer 13 is provided on the surface of the attachment area 122 facing the user's skin side, so that the direct attachment adhesive layer 13 can be directly attached to the user's skin.

[0028] In this embodiment, there are a pair of wing portions 12, which are respectively arranged on the left and right sides of the body portion 11, and the body portion 11 is fixed on the user's breast through the pair of wing portions 12.

[0029] The adjustment area 121 is configured as a telescopic structure so that the position of the attachment area 122 is adjustable to adapt to breast shapes of different sizes. In this embodiment, the adjustment area 121 includes a number of grooves 1211. At the same time, the width direction of the grooves 1211 is parallel to the telescopic direction of the adjustment area 121. Specifically, in this embodiment, the width direction of the grooves 1211 is the left-right direction, and at the same time, the telescopic direction of the adjustment area 121 is also the left-right direction, so that the position of the attachment area 122 is adjustable in the left-right direction.

[0030] It can be understood that by setting the grooves 1211, on the one hand, the adjustment area has the ability to expand and contract in the left-right direction, and on the other hand, the formation of the grooves 1211 gives the adjustment area 121 an elastic force. When the grooves 1211 are further formed by hot pressing, the grooves 1211 have the ability to maintain a fixed shape, so that the adjustment area 121 can expand and contract.

[0031] In a specific embodiment, the grooves 1211 have a width of 1-3 mm and a depth of 1-3 mm.

[0032] In addition, in the present embodiment, the bottom layer 113 is PE, and an outer layer 114 is arranged outside the bottom layer 113. The wing 12 is an outward extension of the bottom layer 113, that is, in the present embodiment, the wing 12 and the bottom layer 113 are an integral structure. At the same time, it can be understood that the direct adhesive layer 13 is arranged on the surface of the bottom layer 113 facing the skin. In this form, on the one hand, the direct adhesive layer 13 will not penetrate to the back side of the bottom layer 113. On the other hand, due to the formation of the groove 1211 on the bottom layer 113, this part of the area has higher softness and elasticity, so as to have a better use experience. At the same time, an outer layer 114 is arranged outside the bottom layer 113, and a better touch is formed by the outer layer 114.

[0033] It can be understood that the outer layer 114 can be a non-woven fabric.

[0034] Furthermore, the wing portion 12 can be folded to the side facing the bottom layer 113 , and a release layer 14 is provided on the direct-attach adhesive layer 13 to protect the direct-attach adhesive layer 13 .

[0035] Furthermore, the main body 11 also includes elastic rubber bands 115 arranged on both sides of the main body 11, and the extension direction of the elastic rubber bands 115 is perpendicular to the expansion and contraction direction of the adjustment area 121. In this case, the adaptive straight-fitting breast pad can be formed into a hemispherical shape to adapt to the shape of the breast.

[0036] Furthermore, an outer layer 15 is provided on the outside of the surface layer 11, and the outer layer 15 is combined with the surface layer 11 along the periphery to form a pocket shape. On the one hand, the connection on both sides of the outer layer makes it easier for the main body 11 to form a hemispherical shape. On the other hand, the pocket setting can accommodate overflowing milk to prevent the milk from contaminating clothes.

[0037] Please refer to Figure 5 In the second embodiment of the present application, the wing portion further includes a wing layer 220, and the wing layer 220 further includes a connection area 223 connected to the main body 11, and the connection area 223 is located between the outer layer 214 and the bottom layer 213, that is, the connection area 223 is sandwiched by the outer layer 214 and the bottom layer 213. In this case, the wing layer 220 can be made of a softer material. In a specific embodiment, the wing layer 220 can be made of a low-irritation, soft material, such as a weight per unit area of ​​10 to 60 g / m 2 Gauze, cotton cloth, spunlace non-woven fabric, hot air non-woven fabric and other sheet materials.

[0038] Please refer to Figure 11, meanwhile, there are also several micro - wrinkles 2210 in the groove 2211. The micro - wrinkles 2210 can be in the form of protrusions and depressions. By arranging the micro - wrinkles 2210 in the groove 2211, on the one hand, the telescopic adjustment range can be further increased, and on the other hand, the adjustment area 221 can have a better touch feeling, that is, when the adjustment area 221 contacts the skin, it has a better touch feeling.

[0039] Furthermore, the protrusion height of the micro - wrinkles 2210 can be 0.1 - 0.3 mm.

[0040] Furthermore, the extending direction of the micro - wrinkles 2210 is different from that of the groove 2211, and the extending direction of the micro - wrinkles 2210 intersects with that of the groove 2211 to form a better touch feeling.

[0041] Please refer to Figure 6 , in the third embodiment of the present application, the adjustment area 421 includes a first wrinkled part 4211 and a second wrinkled part 4141. Among them, the first wrinkled part 4211 is formed by the wing layer 420, and the second wrinkled part 4141 is formed by the outer attached layer 414. Meanwhile, a local area of the first wrinkled part 4211 abuts against the second wrinkled part 4141 and several cavities 4210 are formed in the adjustment area 421. With this structural form, on the one hand, the adjustment area 421 has a better touch feeling on both the side facing the skin and the side facing away from the skin, and it will not produce a clamping effect on the skin after the length of the adjustment area 421 changes. On the other hand, this way can maintain the shape after the length changes, more specifically, reduce the resilience effect of the adjustment area 421, and further improve the use comfort.

[0042] Furthermore, the outer attached layer 414 also includes an outer bonding area 4142 located outside the second wrinkled part 4141 and an inner bonding area 4143 located inside the second wrinkled part 4141. The outer bonding area 4142 is combined with the attachment area, and at the same time, the inner bonding area 4143 is combined with the connection area 423. Through this form, the risk of the adhesive overflowing in the direct - attachment adhesive layer is further reduced and the stability of the wing connection is maintained.

[0043] Please refer to Figure 7 , in the fourth embodiment of the present application, the wing layer is a part of the surface layer 511 extending outward, that is, the wing layer and the surface layer 511 are of an integral structure, and the first wrinkled part is formed by a part of the surface layer 511. In this form, the bottom layer 513 is clamped by the surface layer 511 and the outer attached layer 514. In this way, the first wrinkled part of the wing layer can be directly formed by using the softer surface layer 511.

[0044] Please refer to Figure 8, in the fifth embodiment of the present application, in this embodiment, the attachment area is also set to be adjustable. The attachment area includes a connecting portion, a folding portion 6222 and an end portion 6221 that are folded from the connecting portion towards the surface layer direction. Among them, the end portion 6221 is connected to the adjustment area 621, and there is a separation cavity 6220 between the folding portion 6222 and the connecting portion. The direct attachment adhesive layer 63 is provided on the folding portion 6222. When it is necessary to adjust the position of the direct attachment adhesive layer 63, a part of the direct attachment adhesive layer 63 can be adhered to the adjustment area 621 along the end portion 6221, so that the position of the direct attachment adhesive layer 63 moves towards the main body portion. And when the direct attachment adhesive layer 63 adhered to the adjustment area 621 is released, the position of the folding portion 6222 moves outward. In this way, the position of the direct attachment adhesive layer 63 can be finely adjusted. Combining with the adjustment of the adjustment area 621, the use experience is better.

[0045] Please refer to Figures 9 - 10 , in the seventh embodiment of the present application, in this embodiment, the bottom layer 713 includes a first outer edge portion 7131, and the outer attachment layer 714 further includes a second outer edge portion 7141. There is an accommodation cavity 720 between the first outer edge portion 7131 and the second outer edge portion 7141. The adjustment area 721 is located in the accommodation cavity 720. In this case, the change of the adjustment area 721 will not cause friction to the skin, further improving the comfort.

[0046] Furthermore, the outer attachment layer 714 and the bottom layer 713 on the upper and lower sides of the accommodation cavity 720 are combined, so that the accommodation cavity 720 forms a cavity with only one end open, and the wing portion extends from this opening.

[0047] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
