AI Technical Summary
In use, existing absorbent products are prone to move downward due to loose underwear or movement, and are more likely to move downward due to gravity, resulting in poor contact with the skin and unable to maintain a good fit.
A fully suspended two-piece absorbent article is designed, and its body includes a layered surface layer, an absorbent layer, an inner bottom layer and an outer bottom layer. The inner bottom layer is an elastic film that can stretch in the length direction. The surface layer has a fold that can extend in the length direction. A separation zone is provided between the inner bottom layer and the outer bottom layer, allowing the inner bottom layer and the surface layer to expand in the length direction.
Through this design, the absorbent article can maintain a fit with the skin during exercise, avoiding excessive separation or side leakage. At the same time, the wrinkled structure of the surface layer improves the touch, and the separation zone is the extension space of the elastic membrane to avoid affecting the absorbent layer.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of absorbent articles, in particular to a suspended and fitted absorbent article. Background Art
[0002] Absorbent products such as sanitary napkins, panty liners, and diapers are widely used in people's daily lives. In order to prevent leakage of body fluids, absorbent products are usually provided with a component called a three-dimensional guard. The three-dimensional guard is formed by the contraction of the elastic material, so that the partition material constituting the three-dimensional guard stands up, thereby forming a vertical barrier on both sides.
[0003] However, it is found during use that absorbent articles such as sanitary napkins are usually adhered to underwear by adhesive backing, so that the side of the absorbent article facing the skin cannot maintain good contact with the skin, especially when the underwear is loose or during exercise, the absorbent article is positioned lower and is more likely to move or shift downward under the action of gravity, making it more difficult for the absorbent article to maintain contact or fit with the skin. The solutions currently proposed by people, such as the patent document with document number CN101090691A and name of sanitary napkin, propose to set a raised portion on the side of the main body close to the skin, and the raised portion corresponds to the crotch portion. However, this method makes the raised portion always "sandwiched" in the crotch portion, but some people feel very uncomfortable in actual use.
[0004] Therefore, it is necessary to provide a new solution to solve the above problems. Utility Model Content
[0005] Therefore, the utility model provides a fully suspended two-piece absorbent article to solve the above technical problems.
[0006] A suspended fit absorbent product comprises a body having a length direction and a width direction, wherein the body comprises a surface layer, an absorbent layer, and an inner bottom layer which are stacked, and the body further comprises an outer bottom layer which is arranged at the lower side of the inner bottom layer, wherein the inner bottom layer is an elastic film which can be stretched at least along the length direction, the body comprises a main absorbent area, the surface layer comprises a folded portion which can be stretched along the length direction, and at least one separation area is included between the inner bottom layer and the outer bottom layer.
[0007] Wherein, the main body comprises a main absorption zone, and the folded portion is arranged in the main absorption zone.
[0008] There is only one separation zone, and the separation zone is arranged corresponding to the main absorption zone.
[0009] Wherein, the separation zone runs through the width direction of the body.
[0010] Wherein, wings are arranged on both sides of the main absorption area, the surface layer and the inner bottom layer do not extend to the wings, and the separation area corresponds to the position of the wings.
[0011] Wherein, the elongation at break of the inner bottom layer along the length direction is 110% to 200%.
[0012] Wherein, the ratio of the length of the pleated portion after stretching to the length before stretching is 2:1 to 1.2:1.
[0013] Wherein, three-dimensional guards are also arranged on both sides of the main absorption area, and the three-dimensional guards include a guard part and elastic rubber bands arranged at the ends of the guard part, and the elastic force of the elastic rubber bands is greater than the elastic force of the inner bottom layer along the length direction.
[0014] Wherein, the elastic rubber band includes two ends and a breakpoint connection point between the two ends, and the two ends are arranged outside the separation area.
[0015] Wherein, the elastic film is a TPU elastic film.
[0016] Beneficial effect: The embodiment of the utility model provides a suspended fitting absorbent product, including a body with a length direction and a width direction, the body including a stacked surface layer, an absorbent layer, and an inner bottom layer, the body also including an outer bottom layer arranged on the lower side of the inner bottom layer, wherein the inner bottom layer is an elastic film that can be stretched at least along the length direction, the body includes a main absorption area, the surface layer includes a plurality of folds that can be stretched along the length direction, and the inner bottom layer and the outer bottom layer include at least one separation area. Through the above-mentioned arrangement, the inner bottom layer and the surface layer can both be stretched in the length direction, so that on the one hand, during exercise, for example, the absorbent product can maintain contact with the skin without excessive separation, side leakage, etc. On the other hand, since the surface layer is configured to have folds that can be stretched along the length direction, the surface layer has a better touch.

DETAILED DESCRIPTION
[0021] The embodiment of the utility model provides a fully suspended two-piece absorbent product, and the application will be further described below with reference to the accompanying drawings.
[0022] At the same time, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0023] Please refer to the attached Figures 1 to 3 The absorbent article provided in the embodiment of the present application includes a main body 10, wherein the main body 10 includes a surface layer 11, an absorbent layer 12, an inner bottom layer 13 and an outer bottom layer 14.
[0024] The main body 10 is generally in the shape of a strip, including a length direction and a width direction. Figure 1 Its length direction is the up-down direction, and its width direction is the left-right direction. The main body 10 includes a main absorption area 101, which is an area corresponding to the body fluid discharge area. The absorbent article also includes wings 102, which are usually located on the left and right sides of the main absorption area 101. Usually, the wings 102 protrude from the main body 10 and can be folded back and attached to the underwear.
[0025] The surface layer 11 is arranged on the side close to the user's skin, and the surface layer 11 should be at least partially liquid-permeable. The liquid-permeable means that body fluids can pass through the surface layer 11 and enter the structural layer below the surface layer 11, such as the absorption layer 12. Usually, the body fluids can also diffuse along the surface layer 11 to further improve the absorption efficiency of the absorbent to the body fluids.
[0026] The at least partially liquid-permeable means that at least the area of the surface layer 11 corresponding to the body fluid discharge area is liquid-permeable, and the body fluid discharge area may be a vaginal opening, a urethral opening, or the like.
[0027] Since the surface layer 11 is in contact with the skin, it is preferred to select low-irritation and soft materials, such as gauze, cotton, spunlace non-woven fabrics, hot air non-woven fabrics and other sheet materials with a unit area weight of 10 to 60 g / m2. More preferably, hot air non-woven fabrics composed of thermoplastic synthetic fibers can be used. As the synthetic fibers constituting the above-mentioned hot air non-woven fabrics, polyolefin fibers such as polyethylene (PE) fibers and polypropylene (PP) fibers, polyester fibers, polyamide fibers such as nylon, etc. can be used. In some optional embodiments, natural fibers or viscose fibers can also be added at the same time to further reduce irritation to the skin. These natural fibers can include wood fibers, cotton fibers, etc.
[0028] The absorption layer 12 is stacked under the surface layer 11. Specifically, the absorption layer 12 is a three-dimensional network structure formed by entanglement of a number of fibers that are appropriately connected. A number of pores are distributed between the three-dimensional network structure, and body fluids can be absorbed and diffused through these pores. In a preferred embodiment, a polymer absorbent material (SAP) is included between the three-dimensional network structure to further absorb and retain body fluids through the polymer absorbent material. It can be understood that the fibers can be fluff pulp.
[0029] Furthermore, the absorption layer 12 may also include a covering layer, which covers or wraps the three-dimensional network structure. At the same time, the covering layer is a liquid-permeable material. In some specific embodiments, the covering layer may be a non-woven fabric or toilet paper. At the same time, the covering layer is also preferably made of soft sheet materials such as gauze, cotton, spunlace non-woven fabric, hot air non-woven fabric, toilet paper, etc. with a unit area weight of 10 to 60 g / m2. More preferably, the covering layer has a lower basis weight relative to the surface layer 11.
[0030] The inner bottom layer 13 is stacked under the absorbent layer 12. In order to prevent body fluids from passing through the surface layer 11 and contaminating the user's clothes, the inner bottom layer 13 is a water-repellent material. The surface layer 11 and the inner bottom layer 13 are combined along the edge of the inner bottom layer 13, so that the surface layer 11 and the inner bottom layer 13 are combined into an outer peripheral edge portion, and the surface layer 11 and the inner bottom layer 13 are surrounded along their edges to form a accommodating space, and the absorbent layer 12 is accommodated in the accommodating space. The combination refers to the connection of the combined materials to form a whole, which can usually be formed by hot melting or bonding. The hot melting can be achieved by heating the material itself to a melting point temperature, locally melting it, and forming a connection after solidification, or by external energy such as ultrasound acting on the material to cause the material to locally melt at high temperature, and forming a connection after solidification. The bonding can be achieved by using an adhesive to connect adjacent materials under the action of the adhesive.
[0031] The outer bottom layer 14 is arranged on the lower side of the inner bottom layer 13, and the lower side refers to the side where the outer bottom layer 14 is arranged opposite to the surface layer 11. At the same time, the outer bottom layer 14 is also made of water-repellent material, specifically, it can be PE film, SMS non-woven fabric, non-woven fabric with water-repellent surface treatment, etc.
[0032] The outer bottom layer 14 and the inner bottom layer 13 include a plurality of joints 131 for joining the outer bottom layer 14 and the inner bottom layer 13, and at least one separation area 132 located between adjacent joints 131. The separation area 132 runs through the width direction of the main body 10. The running through the width direction of the main body 10 means that in the separation area 132 along the width direction of the main body 10, the outer bottom layer 14 and the inner bottom layer 13 are completely separated, while in the area corresponding to the joint 131, the outer bottom layer 14 and the inner bottom layer 13 are combined. Preferably, the joint 131 extends to the edge of the inner bottom layer 13 in the width direction and to the upper and lower edges of the surface layer 11 in the length direction. In this case, the outer bottom layer 14 and the inner bottom layer 13 are combined into a whole.
[0033] It can be understood that a connecting component, such as adhesive, for fixing the body 10 to the underwear is provided on the side facing away from the outer bottom layer 14 and the inner bottom layer 13, and a protective component, such as release paper, for preventing the connecting device from being used unexpectedly may also be provided.
[0034] At the same time, the inner bottom layer 13 is an elastic film that can be stretched at least in the length direction, and the surface layer 11 includes a pleated portion 111 that can be stretched at least in the length direction. Please refer to Figure 2 When worn, the outer bottom layer 14 is fixed to the underwear through the connecting parts, that is, the outer bottom layer 14 will be limited in position and limited by the shape of the clothing itself, while the inner bottom layer 13 and the pleated portion 111 can be stretched in the length direction, so that on the one hand, during exercise, the absorbent product can maintain contact with the skin without excessive separation, side leakage, etc. On the other hand, since the surface layer 11 is configured to have the pleated portion 111 that can be stretched in the length direction, the surface layer 11 has a better touch. On the third hand, since the separation area 132 is provided as the stretching space of the elastic membrane and the loose structure of the absorbent layer 12, the absorbent layer 12 will not be affected during the stretching or deformation of the inner bottom layer 13 and the surface layer 11.
[0035] Furthermore, there is only one separation zone 132 , and the separation zone 132 corresponds to the main absorption zone 101 .
[0036] Furthermore, the pleated portion 111 is disposed in the main absorption region 101 .
[0037] It can be understood that the elastic film can be a TPU elastic film, and the elongation at break of the elastic film is greater than or equal to 75%. More preferably, the elongation at break of the inner bottom layer 13 along the length direction is 110% to 200%.
[0038] The folded portion 111 includes a plurality of folded bodies, which are alternately arranged at the protruding portion and the recessed portion, and the cross section of the folded body is S-shaped, so that the folded portion 111 can be stretched along the length direction.
[0039] It can be understood that the ratio of the length of the pleated portion 111 after stretching to the length before stretching is 2:1 to 1.2:1, so that when the inner bottom layer 13 and the pleated portion 111 are stretched at the same time, the absorbent layer 12 will not be overstretched to cause the absorbent layer 12 to break. More preferably, the ratio of the length of the pleated portion 111 after unfolding to the length before unfolding is 1.8:1 to 1.3:1.
[0040] Furthermore, three-dimensional guards 15 are provided on both sides of the main absorption area 101. The three-dimensional guards 15 include a guard portion 151 and an elastic rubber band 152 provided at the end of the guard portion 151. It can be understood that the elastic rubber band 152 is preset with an elastic force that contracts toward the main absorption area 101. In further research, it was found that when the three-dimensional guard 15 is provided, the elastic force of the elastic rubber band 152 can cooperate with the elastic membrane, so that the area corresponding to the separation area 132 can more easily form a bulge toward the skin.
[0041] Furthermore, the elastic force of the elastic rubber band 152 is greater than the elastic force of the inner bottom layer 13 along the length direction. Furthermore, the ratio of the elastic force of the elastic rubber band 152 to the elastic force of the inner bottom layer 13 along the length direction is 1.1 to 1.5. When the elastic force of the elastic rubber band 152 is too large, the elastic rubber band 152 may cause greater friction on the skin and cause discomfort. If the elastic force of the elastic rubber band 152 is too small, it may not be able to form a good bulge or may form a reverse bulge.
[0042] Furthermore, the elastic rubber band 152 includes two ends and a breakpoint connection point between the two ends, and the two ends are arranged on the outside of the separation area 132. The outside means that the projections of the two ends of the elastic rubber band 152 on the plane where the separation area 132 is located are located outside the separation area 132, so that the projection of the elastic rubber band 152 on the plane where the separation area 132 is located is a straight line passing through the separation area 132.
[0043] Furthermore, the main absorption area 101 includes a central raised area, and the central raised area is formed by a guide groove arranged around it. Specifically, the guide groove is waist-shaped, including a first linear indentation and a second linear indentation located on the left and right sides, and the first linear indentation and the second linear indentation respectively include an inner concave portion and an outer convex portion, and a bulge toward the middle is formed by the inner concave portion.
[0044] Furthermore, the surface layer 11 also includes an upper end portion, and a first upper connecting portion 131 is included between the upper end portion and the outer bottom layer 14. The surface layer 11 and the outer bottom layer 14 are connected to form a receiving space through the first upper connecting portion 131, and the inner bottom layer 13 is enclosed in the receiving space.
[0045] Furthermore, a second upper joint portion 131 is included between the upper end portion and the inner bottom layer 13 , and the surface layer 11 , the inner bottom layer 13 , and the outer bottom layer 14 are combined into a whole through the second upper joint portion 131 .
[0046] The above structure makes the absorbent article more stable on the one hand, and on the other hand, the outer bottom layer 14 protects the inner bottom layer 13 and prevents shrinkage in other areas outside the separation zone 132, thereby avoiding wrinkles in other areas.
[0047] Furthermore, the surface layer 11 and the inner bottom layer 13 do not extend to the wing 102, that is, the wing 102 is only composed of the outer bottom layer 14. In this case, when the wing 102 is turned outward and adhered and fixed to the underwear, the wing 102 will not form a pulling effect on the surface layer 11 and the inner bottom layer 13, so that the separation area 132 can easily play an elastic and stretchable role. The position of the separation area 132 corresponds to the position of the wing 102, so as to further prevent the wing 102 from pulling on the inner bottom layer 13 when the wing 102 is turned outward.
[0048] The above description is only an implementation method of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present utility model.
