Breast pads and how to use them

Abstract

The present invention provides a breast pad, comprising a main body formed by stacking a surface layer, an absorbent layer, and a bottom layer, wherein a secondary surface layer is detachably provided on the surface layer, the main body comprising a central region and a peripheral region surrounding the central region, the peripheral region comprising a lower region and an upper region, and microcapsules are provided in the secondary surface layer of the upper region or between the secondary surface layer and the surface layer. On the one hand, before or after use of the breast pad, the predetermined area can be cleaned by peeling off the secondary surface layer, thereby eliminating the embarrassment caused by the lack of cleaning materials. On the other hand, the upper region of the main body does not contact the lotion, that is, the upper region can still be utilized, thereby reducing waste. At the same time, if no high-molecular water-absorbing material is provided in the upper region, the use of high-molecular water-absorbing material can be further reduced. In addition, the microcapsules provided in the upper region further improve the utilization rate of the upper region and enhance the cleaning effect.

Technical Field

[0001] The present application relates to a breast pad and a method for using the breast pad. Background Art

[0002] Breast pads are a type of maternal and infant product that prevents milk from leaking out during lactation. As people's living standards continue to improve, they are becoming more and more common.

[0003] In practice, it is found that consumers have the following two problems when using breast pads:

[0004] First, after using breast pads, consumers want to locally clean the nipples or breasts to facilitate breastfeeding, but there are situations where cleaning materials are not provided.

[0005] Secondly, in the process of using existing breast pads, usually only a small area is used. Specifically, the area around the nipple and the area under the breast pad are used to absorb milk. After only a small area is used, it is discarded, which actually causes waste. Summary of the Invention

[0006] To this end, the present invention provides a breast pad to solve the above technical problems.

[0007] A breast pad comprises a main body formed by stacking a surface layer, an absorbent layer and a bottom layer, a secondary surface layer being detachably arranged on the surface layer, the main body comprising a central region and a peripheral region surrounding the central region, the peripheral region comprising a lower region and an upper region, and microcapsules being arranged in the secondary surface layer of the upper region or between the secondary surface layer and the surface layer.

[0032] Main body 10; middle area 101; lower area 102; upper area 103; peripheral area 104; surface layer 11; absorption layer 12; bottom layer 13; subsurface layer 14; polymer water-absorbing material 15; microcapsules 16; first connecting portion 17; second connecting portion 18. DETAILED DESCRIPTION

[0033] Please refer to Figure 1-Figure 4 , an embodiment of the present invention provides a breast pad, and the present application will be further described below with reference to these drawings.

[0034] The breast pad includes a body 10 , and the body 10 includes a surface layer 11 , an absorption layer 12 and a bottom layer 13 which are stacked.

[0035] The surface layer 11 is arranged on the side close to the user's skin. Since it contacts the skin, it is preferably selected to be low-irritation and soft, such as a weight per unit area of 10 to 60 g / m 2 The sheet material can be gauze, cotton, spunlace nonwoven fabric, air-through nonwoven fabric or the like, more preferably, air-through nonwoven fabric composed of thermoplastic synthetic fibers.

[0036] The bottom layer 13 is arranged on the side away from the user's skin. In order to prevent liquid from penetrating the bottom layer 13 and contaminating the user's clothes, the bottom layer 13 is usually made of a water-repellent material, specifically, a PE film, SMS non-woven fabric, etc.

[0037] The absorbent core is disposed between the surface layer 11 and the bottom layer 13. Specifically, the absorbent core is a three-dimensional network structure formed by entanglement of a plurality of fibers that are properly connected, and a plurality of pores are distributed between the three-dimensional network structure.

[0038] A secondary surface layer 14 is also provided on the surface layer 11, and the secondary surface layer 14 is separable from the surface layer 11. The separable setting means that the secondary surface layer 14 can be peeled off from the surface layer 11 under a relatively small external force, but when there is no external force, the secondary surface layer 14 is connected to the surface layer 11. Preferably, this relatively small external force is less than or equal to 3N and greater than or equal to 0.08N, so that on the one hand the secondary surface layer 14 can be stably connected to the surface layer 11, and at the same time, when the secondary surface layer 14 is peeled off from the surface layer 11, it will not cause damage to the secondary surface layer 14 and the surface layer 11. More preferably, the relatively small external force is 0.1-0.5N.

[0039] Please refer to Figure 4 The main body 10 includes an outer peripheral area 104, which refers to an annular area adjacent to the outer edge line of the main body 10. In the outer peripheral area 104, the surface layer 11 and the bottom layer 13 are combined into a whole through the first bonding portion 17. It can be understood that the surface layer 11 and the bottom layer 13 form a hollow accommodating space after being combined in the outer peripheral area 104. The absorbent layer 12 is accommodated in the accommodating space. At the same time, the sub-surface layer 14 is combined with the surface layer 11 and the bottom layer 13 in the outer edge area through the second bonding portion 18. On layer 11, the bonding force of the second bonding part 18 is smaller than the bonding force of the first bonding part 17. The bonding force refers to the force required to separate the materials on both sides of the first bonding part 17 or the second bonding part 18. When the first bonding part 17 is formed by an adhesive, the bonding force of the first bonding part 17 is an adhesive force. When the first bonding part 17 is bonded by mechanical action, the bonding force of the first bonding part 17 is a mechanical force. Similarly, the bonding force of the second bonding part 18 can be an adhesive force or a mechanical force, etc.

[0040] Furthermore, the binding force of the second binding portion 18 is less than 1 / 2 of the binding force of the first binding portion 17 .

[0041] Furthermore, the width of the first combining portion 17 is greater than the width of the second combining portion 18 .

[0042] It can be understood that the sub-surface layer 14 can be peeled off from the surface layer 11 before or after using the breast pad, and the sub-surface layer 14 can be used to wipe the user's predetermined position. At the same time, when the sub-surface layer 14 is peeled off from the surface layer 11 before using the breast pad, it will not affect the use of the main body 10, that is, the main body 10 can still be used normally.

[0043] Specifically, the sub-surface layer 14 may be a non-woven fabric. Preferably, the sub-surface layer 14 is a seaweed non-woven fabric. The seaweed non-woven fabric refers to a non-woven fabric made of seaweed fiber or at least includes seaweed fiber.

[0044] The main body 10 includes a central area 101 and a peripheral area surrounding the central area 101, and the peripheral area includes a lower area 102 and an upper area 103. The central area 101 refers to the area corresponding to the nipple, and the peripheral area refers to the area surrounding the outside of the central area 101. The lower area 102 refers to the area below the central area 101 when the breast pad is attached to the breast. The upper area 103 is the area above the central area 101 when the breast pad is attached to the breast. It can be understood that when lotion overflows from the nipple, under the action of gravity, the lotion will flow to the lower area 102 and be absorbed by the main body 10 of the lower area 102. More specifically, the lotion seeps through the surface layer 11 and is absorbed by the absorption layer 12.

[0045] Furthermore, a polymer water-absorbing material 15 is provided in the absorption layer 12 corresponding to the lower side area 102. More specifically, these polymer water-absorbing materials 15 are accommodated in the pores of the three-dimensional network structure of the absorption layer 12, and the emulsion is accommodated and diffused through the pores of the absorption layer 12, while the emulsion is absorbed and retained by the polymer water-absorbing materials 15.

[0046] Preferably, the polymer water-absorbing material 15 is disposed only in the absorbent layer 12 corresponding to the lower region 102, while not in the upper region 103. Furthermore, preferably, the area of the lower region 102 is smaller than that of the upper region 103. The reason for not disposing the polymer water-absorbing material 15 in the upper region 103 is that, on the one hand, disposing the polymer water-absorbing material 15 only in the lower region 102 can reduce the amount of water-absorbing material used, and, on the other hand, not disposing the polymer water-absorbing material 15 in the upper region 103 can prevent the formation of bulges or protrusions in this region after absorbing lotion, which would prevent this region from being used for wiping the intended area. This will be further explained in the following description in conjunction with the use of the breast pad.

[0047] Furthermore, the polymer water-absorbing material 15 has a particle size of 50 μm to 900 μm. At the same time, the polymer water-absorbing material 15 is evenly distributed in the absorption layer 12 of the lower area 102 .

[0048] Microcapsules 16 are arranged in the sub-surface layer 14 described in the upper side area 103 or between the sub-surface layer 14 and the surface layer 11. The core material of the microcapsule 16 includes a detergent, so that when the predetermined area is cleaned, the microcapsule 16 is squeezed to release the detergent, thereby facilitating cleaning. Specifically, the microcapsule 16 also includes a wall material, and the wall material can be gum arabic, gelatin and sodium alginate, etc. The detergent can be selected from alkyl aromatic sulfonates, secondary alkyl fatty hydrocarbon sulfonates, alkyl sulfates, sodium lauryl polyoxyethylene ether sulfate, sodium lauryl sulfate, aminopropionates, iminopropionates, polyoxyethylene ether, alkyl glycosides and their derivatives, fatty alcohol polyoxyethylene ethers, alcohol amides, etc. It can be understood that the microcapsule 16 can encapsulate the core material in the wall material by coagulation, complex coagulation, freeze drying, spray drying, etc. to form a microcapsule 16 structure.

[0049] Furthermore, microcapsules 16 are only provided in the sub-surface layer 14 corresponding to the upper side area 103 or between the sub-surface layer 14 and the surface layer 11, and no microcapsules 16 are provided in other areas. This arrangement is to avoid the unexpected release of microcapsules 16, which may contaminate other areas and cause a decrease in absorption performance.

[0050] It can be understood that when the microcapsules 16 are provided on the sub-surface layer 14, the microcapsules 16 are provided inside the sub-surface layer 14. More specifically, when the sub-surface layer 14 is made of seaweed non-woven fabric, the microcapsules 16 are fixed on the fibers forming the seaweed non-woven fabric. In a specific embodiment, the microcapsules 16 can be added to the mixed fibers containing seaweed fibers. The microcapsules 16 are fixed on the fibers during the carding process. After drying, the microcapsules 16 are formed inside the seaweed non-woven fabric.

[0051] Furthermore, the microcapsules 16 have a particle size of 1-20 μm. When the particle size is too large, they are easily broken during the process of forming the seaweed non-woven fabric. When the particle size is too small, it is difficult to break them during use to release the core material.

[0052] In addition, the core material may further include a moisturizer or an antibacterial agent. The moisturizer may mainly include polyols such as glycerol, diglycerin, polyethylene glycol, propylene glycol, hexylene glycol, and polypropylene glycol; sugars such as sorbitol, glucose, xylitol, maltitol, and mannitol; the antibacterial agent is preferably a natural antibacterial agent, specifically seaweed extract, aloe extract, amino acid, sodium lactate, urea, hyaluronic acid, sodium pyrrolidonecarboxylate, ceramide, collagen, chitin derivatives, mucopolysaccharides, chondroitin sulfate, lactic acid and its salts (such as sodium lactate), corn steep liquor, urea, triglycerides, palmitic acid, myristic acid, stearic acid, silicone, sodium pyrrolidonecarboxylate, etc.

[0053] In order to facilitate the user to distinguish between the lower side area 102 and the upper side area 103, so that the user can easily set the upper side area 103 upward and the lower side area 102 downward, a marker is provided on the upper side area 103 or the lower side area 102. Preferably, in one embodiment, a guide groove is provided in the lower side area 102, and a guide groove is not provided in the upper side area 103. In this case, the guide groove provided in the lower side area 102 can facilitate the diffusion of the emulsion. At the same time, since the guide groove is only provided in the lower side area 102 to form a separation from the upper side area 103, in another embodiment, the microcapsule 16 also includes a pigment or pigment to form color in the upper side area 103, similarly, the upper side area 103 is separated from the lower side area 102.

[0054] The following is further explained in conjunction with the method of use of this breast pad.

[0055] S1: providing the aforementioned breast pad, squeezing the microcapsules 16 in the upper region 103, and releasing the core material of the microcapsules 16;

[0056] It can be understood that when the microcapsules 16 are squeezed, the core materials of the microcapsules 16 are released and then absorbed by the sub-surface layer 14 .

[0057] S2: peeling off the sub-surface layer 14 and wiping the predetermined area with the sub-surface layer 14;

[0058] It can be understood that the predetermined area refers to the location that the user needs to wipe, such as the nipple area;

[0059] S3: Fix the main body 10 to the underwear, with the upper side area 103 facing upward and the lower side area 102 facing downward.

[0060] It is understandable that, usually, a fixing device, such as an adhesive layer, can be provided on the bottom layer 13 to adhere or fix the main body 10 to the underwear. Of course, devices such as hidden buttons, laces, and inserts can also be provided to fix the main body 10 to the underwear.

[0061] S4: Wear your bra and make sure the breast pads are attached to your breasts.

[0062] It can be understood that in this usage mode, the sub-surface layer 14 is peeled off before use to wipe the predetermined area, thereby facilitating the use without wiping material.

[0063] In another usage mode, it can be used as follows.

[0064] S11: Provide the above-mentioned breast pad and fix the main body 10 to the underwear, with the upper side area 103 facing upward and the lower side area 102 facing downward.

[0065] S12: Wear bra and make sure the breast pads are attached to your breasts and use breast pads.

[0066] S13: peeling the body 10 from the underwear;

[0067] S14: squeezing the microcapsules 16 in the upper area 103 to release the core material of the microcapsules 16;

[0068] S15: Peel off the sub-surface layer 14 and use the sub-surface layer 14 to wipe the predetermined area.

[0069] It can be understood that in this usage scenario, the predetermined position or area needs to be wiped after use. In this wiping, the upper area 103 of the sub-surface layer 14 is used. The sub-surface layer 14 of the upper area 103 is located above the nipple so that it will not come into contact with the lotion, so that this area can be directly used to wipe the predetermined area. In addition, the microcapsules 16 release detergents, moisturizers or bactericides to enhance the wiping effect.

[0070] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
