Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, specifically to a leak-proof component with good uprightness, a light incontinence napkin, and a sanitary napkin. Background Technology

[0002] Disposable absorbent items such as sanitary napkins and incontinence pads consist of a liquid-permeable upper layer, a liquid-impermeable lower layer, and an absorbent layer between the upper and lower layers that absorbs and retains liquid. Furthermore, to ensure leak-proof properties on both longitudinal sides, disposable absorbent items have raised leak-proof components (also known as three-dimensional guards) on both sides.

[0003] Currently, most leak-proof components in absorbent items on the market use spunbond nonwoven fabric or hot-air nonwoven fabric directly wrapped around elastic bands. When worn, this design allows the elastic band to come into close contact with the skin through the nonwoven fabric, and when stretched, it forms a serrated shape, causing friction against sensitive skin areas such as the legs during activity, leading to discomfort or even chafing. Furthermore, this sheet-like leak-proof component, relying on the elasticity of the elastic band for support, has poor stability under lateral forces and is prone to deformation, posing a risk of side leakage. Utility Model Content

[0004] This invention provides a leak-proof component with good uprightness, a light incontinence napkin, and a sanitary napkin to solve the technical problems of leak-proof components being prone to tipping over and deformation in the prior art.

[0005] To solve the above problems, the leak-proof component with good uprightness provided by this utility model adopts the following technical solution: it includes an outer covering layer, which is arranged in a closed ring on the left and right sides of the upper surface of the absorbent article;

[0006] An elastic member is disposed within an outer covering layer. The elastic member includes a buffer layer and an elastic element wrapped within the buffer layer. At least three elastic elements are provided, with at least two elastic elements provided on the side of the outer covering layer closest to the inside of the absorbent material, and at least one elastic element provided on the side of the outer covering layer closest to the outside of the absorbent material.

[0007] As a further improvement, the outer covering layer has three elastic members on the side near the inside of the absorbent material, and the outer covering layer has one elastic member on the side near the outside of the absorbent material.

[0008] As a further improvement, the outer covering layer is made of non-woven fabric or cotton fabric.

[0009] As a further improvement, the buffer layer is made of non-woven fabric or cotton fabric.

[0010] As a further improvement, the elastic element is a rubber band or an elastic fiber strip.

[0011] This utility model also provides a light incontinence towel, which has the above-mentioned leak-proof component with good uprightness.

[0012] This utility model also provides a sanitary napkin, which has the above-mentioned leak-proof component with good stand-up properties.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] 1. The leak-proof component of this utility model adopts a hollow tunnel structure design, which makes the contact surface between the skin and the outer covering layer on the arc surface, reducing friction and thus improving the comfort of wearing; in addition, this structure can avoid the appearance of jagged edges, reducing the risk of skin abrasions caused by friction.

[0015] 2. The elastic elements in this invention employ a distributed design, improving both comfort and leak prevention in the three-dimensional protective barrier. Three elastic elements are located on one side of the outer covering layer closest to the inside of the absorbent material, while one elastic element is located on the other side of the outer covering layer. This reduces the possibility of excessive localized tension in the three-dimensional protective barrier. During wear, because the separately located elastic element is relatively far from the groin, and the absorbent material tends to bend downwards or upwards on both sides, the separately located elastic element is stretched relatively longer. This ensures that the tension generated by this independent elastic element is not excessive, while still allowing the outer covering layer to better conform to the skin, thereby improving comfort while reducing the risk of leaks.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] In existing technologies, leak-proof components of absorbent items often use spunbond nonwoven fabric or hot-air nonwoven fabric to directly wrap elastic bands. When worn, this design allows the elastic band to come into close contact with the skin through the nonwoven fabric, and when stretched, it forms a serrated shape, causing friction against sensitive skin areas such as the legs during activity, leading to discomfort or even chafing. Furthermore, this sheet-like leak-proof component, relying on the elasticity of the elastic band for support, has poor stability under lateral forces and is prone to deformation, posing a risk of side leakage.

[0024] To address the aforementioned issues, the elastic elements of this invention employ a distributed design. This distributed design does not mean the elastic elements are evenly distributed within the outer covering layer; rather, based on the stress distribution, the elastic elements are distributed on both the left and right sides of the outer covering layer. Taking four elastic elements as an example (keeping the total number of elastic elements constant), three are positioned on the skin-closed side of the outer covering layer (i.e., the inner side close to the absorbent material), and the remaining elastic element is positioned on the other side of the three-dimensional protective barrier. This arrangement reduces the tension on the skin-closed side of the leak-proof component during use. Furthermore, by reducing the number of elastic elements from four to three, the spacing between the three elements is relatively greater, avoiding excessive stress concentration and improving wearing comfort. The independently positioned elastic element on the other side can stretch the outer covering layer outwards during use, improving the fit between the outer covering layer and the skin, reducing the gap between them, and thus improving side leakage. Because the independently positioned elastic element is closer to the outer side of the absorbent material, its stretching deformation during wear is relatively greater. Therefore, generally only one independently positioned elastic element is used within the outer covering layer to avoid excessive tension affecting comfort.

[0025] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0026] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0027] Example 1 of the leak-proof component with good uprightness provided by this utility model:

[0028] like Figure 1 As shown, the leak-proof component includes an outer covering layer 1 and an elastic member disposed within the outer covering layer 1.

[0029] The outer covering layer 1 is arranged in a closed ring on the left and right sides of the upper surface of the absorbent item. The absorbent item includes, but is not limited to, sanitary napkins, incontinence pads, and sanitary underwear. In this embodiment, the outer covering layer 1 is made of cotton fabric.

[0030] An elastic component is disposed within the outer covering layer 1. The elastic component includes a buffer layer 2 and an elastic element 3 wrapped within the buffer layer 2. The buffer layer 2 is made of non-woven fabric, and the elastic element 3 is made of rubber. At least three elastic elements 3 are provided. Three elastic elements 3 are provided on the side of the outer covering layer 1 closest to the inside of the absorbent material, and one elastic element 3 is provided on the side of the outer covering layer 1 closest to the outside of the absorbent material.

[0031] In this embodiment, the left and right sides of the elastic member are glued to the bottom of the outer covering layer 1, and the elastic member forms an arched structure.

[0032] This embodiment also provides a light incontinence towel, which has the aforementioned leak-proof component with good uprightness.

[0033] This embodiment also provides a sanitary napkin having the aforementioned leak-proof component with good stand-up properties.

[0034] During use, the three elastic elements 3 closest to the inner side of the absorbent material, being near the groin, have relatively smaller deformation, preventing excessive tension. Furthermore, the larger spacing between the three elastic elements 3 avoids concentrated tension, improving comfort. The other elastic element 3, being further away from the groin, has a larger deformation, allowing even a single elastic element 3 to generate sufficient tension, increasing the contact area between the outer covering layer 1 and the skin 4, ensuring a better fit and reducing side leakage. Simultaneously, this independently designed elastic element 3 can stretch the absorbent material outwards, reducing wrinkles. Wrinkles reduce the absorbent area, hindering the rapid absorption of urine or menstrual blood.

[0035] Embodiment 2 of the leak-proof component with good uprightness provided by this utility model:

[0036] Its main difference from Example 1 is:

[0037] In Example 1, the elastic member is glued to the bottom of the outer covering layer on both sides, and the elastic member forms an arched structure.

[0038] In this embodiment, the upper surface of the elastic member is bonded to the upper part of the inner surface of the outer covering layer by adhesive. This reduces the number of processing steps, as only adhesive needs to be applied to the upper surface of the elastic member or the upper part of the inner surface of the outer covering layer, thus reducing the processing difficulty.

[0039] Embodiment 3 of the leak-proof component with good uprightness provided by this utility model:

[0040] The main difference between it and Example 2 is that:

[0041] In this embodiment, the buffer layer is a sheet-like structure that wraps around the elastic element end to end, with the interface left on one side, forming a single-sided open structure, which further reduces the processing difficulty of the elastic element.

[0042] While this specification has shown and described various embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and essence of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
