Description

Technical Field

[0001] The present disclosure relates to the technical field of sanitary products, and in particular to an absorbent product that prevents side leakage. Background Art

[0002] Sanitary napkins are absorbent products used to absorb menstrual blood during a woman's menstrual cycle. Currently, sanitary napkins on the market primarily consist of a top layer, a core layer, and a backing film. Some also include a pair of wings located on either side of the core layer. When worn, sanitary napkins are prone to deformation and displacement due to the lack of support provided by the material, resulting in side leakage.

[0003] For sanitary napkins with wings, the wings need to be attached to the underside of underwear during use, which causes downward force on the sanitary napkin, resulting in a poor fit. This poor fit also leads to poor leakage prevention, making menstrual blood more likely to leak out the sides.

[0004] To address this issue, some existing sanitary napkins incorporate protective structures on both sides of the core layer. These structures can be flexible and conform to the body. However, these protective structures are typically made of a single layer of material, which can easily become distorted and wrinkled under the pressure of the user, leaving room for improvement in leak-proofing. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present disclosure provides an absorbent product that prevents side leakage.

[0006] According to a first aspect of the present disclosure, there is provided an absorbent article for preventing side leakage, comprising:

[0035] The present disclosure provides an absorbent product that prevents side leakage, which can be baby diapers, baby diapers, baby pull-up pants, adult diapers, adult care products, sanitary napkins, sanitary pads or menstrual pants, etc. In the embodiments of the present application, the absorbent product that prevents side leakage is a sanitary napkin as an example for specific description.

[0036] The side leakage prevention absorbent product provided by the present disclosure includes: a main body and a side guard. Among them, the main body includes a surface layer, a core layer, and a bottom film layer from top to bottom. The surface layer is a material that is directly close to the human body and is usually made of a soft, skin-friendly, and liquid-conducting material. The core layer has a certain thickness and can absorb and store a certain amount of liquid. When the core layer absorbs to a saturated state, the liquid in the core layer is prone to leakage under the action of squeezing. The bottom film layer arranged below the core layer is made of a water-repellent material. The liquid in the core layer will be blocked when it flows downward to the bottom film layer, thereby preventing the liquid from leaking from under the core layer.

[0037] Liquid in the core layer can seep back into the surface layer. Furthermore, unabsorbed liquid may remain on the surface layer. Liquid on the surface layer can easily leak out from the sides under the pressure of the human body, contaminating the user's clothing, inner thighs, bed sheets, and other items. To address these issues, the present invention provides side guards to prevent side leakage.

[0038] Specifically, the edge guard is provided on the main body and includes a barrier portion disposed above the surface layer, the barrier portion being configured to protrude from the upper surface of the surface layer. Two sets of barrier portions are provided, each configured to extend along the length of the core layer and to be located adjacent to the edges of the long sides of the core layer. The two sets of barrier portions can be arranged parallel to each other and spaced apart on the left and right sides of the surface layer. The two sets of barrier portions can form a dam of a certain height on the main body of the absorbent article to prevent side leakage. Liquid on the surface layer is intercepted by the barrier portions during flow, thereby preventing liquid from leaking from the sides.

[0039] Furthermore, a cavity extending along the length direction of the core layer is provided in the barrier portion, and the barrier portion is configured to deform under the action of an external force, and is configured to rebound after the external force is removed. At least part of the cross section of the barrier portion can be constructed into a ring shape, thereby providing a cavity inside the barrier portion. The cavity helps to improve the support and elasticity of the barrier portion. When subjected to an external force, the barrier portion can be deformed according to the direction and magnitude of the external force. The barrier portion can bear force 360° and has a good anti-deformation effect. When the user wears the absorbent product provided by the present invention, the barrier portion can adjust its shape according to the user's posture changes, so that it can always keep in contact with the human body and prevent side leakage. In addition, the barrier portion with a cavity has at least a double layer of material. Compared with the traditional single-layer protective structure, the present application effectively improves the leakage prevention performance.

[0040] The specific embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0041] refer to Figure 1 and Figure 4 The present disclosure provides an absorbent product for preventing side leakage, comprising: a main body and a side guard. Figure 1 As shown, the main body includes, from top to bottom, a surface layer 1, a core layer 2, and a bottom film layer 3. The surface layer 1, the core layer 2, and the bottom film layer 3 can be combined together by gluing, ultrasonic bonding, heat sealing, etc. to form the main body.

[0042] The surface layer 1 is the material that is in direct contact with the human body, and is usually made of soft, skin-friendly, and fluid-conducting materials, such as cotton materials, hot air non-woven materials, spunlace non-woven materials, 3D non-woven materials, or other materials composited from the above materials.

[0043] The core layer 2 has a certain thickness and can absorb and store a certain amount of liquid. The core layer 2 can adopt a fluff pulp structure or a composite core. Embossing can be provided on the core layer 2 to enhance the absorption effect of the core layer 2. When the core layer 2 absorbs to a saturated state, the liquid in the core layer 2 is prone to leakage under the action of squeezing. The bottom film layer 3 arranged below the core layer 2 is made of a water-repellent material. Specifically, the bottom film layer 3 can be made of a PE film material. The liquid in the core layer 2 will be blocked when it flows downward to the bottom film layer 3, thereby preventing the liquid from leaking from under the core layer 2.

[0044] In one embodiment of the present disclosure, Figure 1 As shown, a back release liner 9 is positioned in the center below the base film layer 3. The back of the base film layer 3 is a smooth, adhesive-coated surface. The back release liner 9 can be attached to the back of the base film layer 3, making it easier to clean and store the sanitary napkin. During use, the user simply removes the back release liner 9 and places the back of the base film layer 3 against the inside of their underwear. This secures the sanitary napkin and prevents it from moving during use.

[0045] The liquid in the core layer 2 may seep back to the surface layer 1. In addition, there will be liquid that has not been absorbed on the surface layer 1. In order to prevent the liquid on the surface layer 1 from leaking sideways, the present invention provides a protective edge on the main body. Figure 1 、 Figure 2 and Figure 4 The edge guard includes a barrier portion 4 provided above the surface layer, and the barrier portion 4 is configured to protrude from the upper surface of the surface layer 1. There are two groups of barrier portions 4, which are configured to extend along the length direction of the core layer 2 and are configured to be located at the edge positions of the long sides of the two sides of the core layer 2. Figure 4 In the viewing direction, the two groups of blocking portions 4 can be parallel to each other and spaced apart on the left and right sides of the surface layer 1 .

[0046] In a specific embodiment of the present disclosure, the barrier portion 4 is configured to protrude 2-10 mm from the upper surface of the top layer 1. The barrier portion 4 can form a 2-10 mm high dam to prevent side leakage on the main body of the absorbent article. Liquid on the top layer 1 will be intercepted by the barrier portion 4 during its flow, thereby preventing the liquid from leaking from the sides.

[0047] refer to Figure 1 and Figure 2 , a cavity 40 extending along the length direction of the core layer 2 is provided in the barrier portion 4, and the barrier portion 4 is configured to deform under the action of an external force, and is configured to rebound after the external force is removed. At least part of the cross section of the barrier portion 4 can be constructed into a ring shape, thereby providing a cavity 40 inside the barrier portion 4. The cavity 40 helps to improve the support and elasticity of the barrier portion 4. When subjected to an external force, the barrier portion 4 can be deformed according to the direction and magnitude of the external force. The barrier portion 4 can bear force 360° and has a good anti-deformation effect. When the user wears the absorbent product provided by the present invention, the barrier portion 4 can adjust its shape according to the user's posture changes, so that it can always keep in contact with the human body and prevent side leakage. In addition, the barrier portion 4 with the cavity 40 has at least a double layer of material. Compared with the traditional single-layer protective structure, the present application effectively improves the leakage prevention performance.

[0048] In one embodiment of the present disclosure, reference Figure 1The blocking part 4 is a hose 42, and a cavity 40 is provided in the hose 42. Specifically, the hose 42 is made of any one of plastic, rubber or silicone. The hose 42 has good water repellency, and its diameter is constructed to be at least greater than 2 mm. When the liquid flows to the edge of the surface layer 1, it can be blocked by the hose 42 protruding from the upper surface of the surface layer 1. In addition, the material of the hose 42 is soft and has a certain elasticity. The hose 42 can be deformed under the action of external force and rebound after the external force is removed. The hose 42 can naturally deform according to the user's posture changes and always keep in touch with the human body, thereby preventing side leakage.

[0049] The edge guard also includes a first fabric layer 41, part of which is configured to wrap the outer wall of the hose 42 and is configured to be bonded to the top of the surface layer 1. The first fabric layer 41 can be made of a water-repellent, skin-friendly non-woven material. Figure 1 As shown, the inner side of the first fabric layer 41 can be adhered to the upper edge of the surface layer 1 via the first adhesive layer 51 and wrapped around the hose 42, thereby fixing the hose 42 at the edge of the long sides of the core layer 2. Since the material of the hose 42 is less skin-friendly, wrapping the hose 42 with the more skin-friendly first fabric layer 41 can improve the comfort of the user wearing the sanitary napkin.

[0050] In one embodiment of the present disclosure, reference Figure 1 and Figure 4 The side of the first fabric layer 41 away from the core layer 2 is constructed to be composited on the bottom film layer 3 to form a wing composite layer, and the middle part of the wing composite layer extends outward to form a wing 7. Figure 1 As shown, the inner side of the first fabric layer 41 is bonded to the surface layer 1, and the outer side thereof extends outward to a position beyond the surface layer 1 and the core layer 2, thereby being directly composited to the bottom film layer 3 to form a wing composite layer.

[0051] like Figure 4 As shown, the sanitary napkin provided in this embodiment is provided with wings 7 on both sides. The upper surface of the wings 7 is the first fabric layer 41, and the lower surface is the base film layer 3. As mentioned above, the back of the base film layer 3 is a smooth surface with adhesive, so the back of the wings 7 is also a smooth surface with adhesive. When in use, the user can fold the wings 7 downward so that the wings 7 wrap around the crotch of the underwear from both sides and adhere to the lower surface of the underwear, thereby further improving the fixation effect of the sanitary napkin.

[0052] In one embodiment of the present disclosure, Figure 1 As shown, wing release paper 8 is provided on both sides of the bottom film layer 3. The wing release paper 8 can be attached to the back of the bottom film layer 3, specifically, on both sides of the corresponding wings 7, so as to facilitate the cleaning and storage of the sanitary napkin.

[0053] The above describes the embodiment in which the barrier portion 4 is a hose 42. The present disclosure also provides an embodiment in which the barrier portion 4 is formed by enclosing a material. Figures 2 to 4 Provide a detailed introduction to this plan.

[0054] In one embodiment of the present disclosure, Figure 2 As shown, the edge guard includes a second fabric layer 43, the inner side of the second fabric layer 43 is configured to be bonded to the upper side of the surface layer 1, and is configured to be bent outward and bonded to the upper side of the second fabric layer 43 to form a blocking portion 4 protruding from the surface layer 1; the second fabric layer 43 is configured to enclose and form a cavity 40. The second fabric layer 43 can be a non-woven fabric material, such as Figure 3 As shown, the inner side of the second fabric layer 43 can be bonded to the upper edge of the surface layer 1 via the first adhesive layer 51, and then bent outward and bonded to the upper side of the second fabric layer 43 via the second adhesive layer 52. The second fabric layer 43 can be bent to enclose and form a cavity 40, thereby supporting the second fabric layer 43 above the surface layer 1, forming a barrier 4 protruding from the surface layer 1.

[0055] When liquid flows to the edge of the surface layer 1, it is blocked by the second fabric layer 43 protruding from the upper surface of the surface layer 1. In addition, because the second fabric layer 43 encloses the cavity 40, the second fabric layer 43 has a certain amount of deformation space. The second fabric layer 43 will deform under the action of external force and rebound after the external force is removed, thereby ensuring that it always fits the human body and prevents side leakage.

[0056] In one embodiment of the present disclosure, Figure 3 As shown, the second fabric layer 43 is at least partially constructed as a double-layer material, with a water-repellent layer 44 disposed between the two layers of second fabric layers 43. The inner portion of the second fabric layer 43 near the core layer 2 can be folded to form a double-layer material, and a water-repellent layer 44, such as a spunbond water-repellent non-woven fabric, can be disposed between the two layers of second fabric layers 43. The water-repellent layer 44 can make the annular area enclosed by the second fabric layer 43 more three-dimensional and more supportive. In addition, the water-repellent layer 44 can prevent liquid from seeping out of the second fabric layer 43, thereby enhancing the effect of preventing side leakage.

[0057] Further, such as Figure 3As shown, at least one elastic band 45 is wrapped between the two second fabric layers 43. The elastic band 45 is configured to extend along the length of the core layer 2. In this embodiment, three elastic bands 45 are wrapped between the two second fabric layers 43, thereby imparting elasticity to the annular area formed by the second fabric layers 43. After the second fabric layers 43 are deformed by an external force, the elastic bands 45 impart a tendency for the second fabric layers 43 to recover their shape, allowing them to rebound after the external force is removed. This ensures that the barrier 4 formed by the second fabric layers 43 maintains constant contact with the human body, preventing side leakage.

[0058] In one embodiment of the present disclosure, reference Figure 2 and Figure 4 The side of the second fabric layer 43 away from the core layer 2 is constructed to be composited on the bottom film layer 3 to form a wing composite layer, and the middle part of the wing composite layer extends outward to form a wing 7. Figure 1 As shown, the inner side of the second fabric layer 43 is bonded to the surface layer 1, and the outer side thereof extends outward to a position beyond the surface layer 1 and the core layer 2, thereby being directly composited to the bottom film layer 3 to form a wing composite layer.

[0059] like Figure 4 As shown, the sanitary napkin provided in this embodiment is provided with wings 7 on both sides. The upper surface of the wings 7 is the second fabric layer 43, and the lower surface is the base film layer 3. As mentioned above, the back of the base film layer 3 is a smooth surface with adhesive, so the back of the wings 7 is also a smooth surface with adhesive. When in use, the user can fold the wings 7 downward so that the wings 7 wrap around the crotch of the underwear from both sides and stick to the lower surface of the underwear, thereby further improving the fixation effect of the sanitary napkin.

[0060] In one embodiment of the present disclosure, reference Figure 1 and Figure 2 The main body also includes a guide layer 6, which is disposed between the surface layer 1 and the core layer 2. The guide layer 6 is configured to guide liquid from one side of the surface layer 1 to the other side of the core layer 2. The guide layer 6 can be made of materials such as hot air non-woven fabric, dust-free paper, spunlace non-woven fabric, spunbond non-woven fabric, etc., thereby facilitating the rapid guidance of liquid from the surface layer 1 to the core layer 2. In addition, the provision of the guide layer 6 helps to ensure unidirectional flow of liquid, preventing liquid in the core layer 2 from back into the surface layer 1, thereby improving the absorption effect.

[0061] In one embodiment of the present disclosure, the surface layer 1 and / or the guide layer 6 contain at least one of tea polyphenols, tea tree essential oil, bamboo charcoal fiber, plant tannins, grapefruit extract, apigenin, aloe vera, chitosan, chamomile, quaternary ammonium salts, graphene, activated carbon, probiotics, Cnidium monnieri, Portulaca oleracea, Prinus utilis, Sophora flavescens, dipotassium glycyrrhizate, Centella asiatica, Gentiana scabra, Artemisia argyi, sodium hyaluronate, ceramide, and Scutellaria baicalensis. It is understood that menstrual blood contains nutrients such as protein, amino acids, and abundant enzymes and antibodies, which are very prone to bacterial growth. If the user changes the sanitary napkin at a long interval, the menstrual blood accumulated on the sanitary napkin is likely to produce an odor. In addition, if the sanitary napkin is worn for a long time, users with sensitive skin are prone to mild allergic reactions. Therefore, antibacterial, deodorizing, and anti-allergic ingredients can be added to either the surface layer 1 or the guide layer 6, or antibacterial, deodorizing, and anti-allergic ingredients can be added to both the surface layer 1 and the guide layer 6. For example, deodorizing ingredients (such as tea polyphenols, tea tree essential oil, bamboo charcoal fiber, plant tannins, grapefruit extract, activated carbon, etc.) can be added to either the surface layer 1 or the guide layer 6. Antibacterial ingredients (such as apigenin, aloe vera, chitosan, chamomile, quaternary ammonium salts, graphene, tea polyphenols, probiotics, etc.) can be added to either the surface layer 1 or the guide layer 6. Anti-allergic ingredients such as Cnidium monnieri, Portulaca oleracea, Prinus utilis, Sophora flavescens, chamomile, dipotassium glycyrrhizate, Centella asiatica, Gentiana scabra, Artemisia argyi, sodium hyaluronate, ceramide, and Scutellaria baicalensis can also be added to either the surface layer 1 or the guide layer 6. It should be noted that the deodorizing, antibacterial, and anti-allergic ingredients are not limited to the above ingredients. These ingredients can slow the growth of bacteria, remove odors, prevent user allergies, and enhance the user experience.

[0062] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
