Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, specifically to a leak-proof structure and hygiene products. Background Technology

[0002] Disposable diapers and pull-up pants are common hygiene products, mainly used by infants and women. These products have an absorbent core in the crotch area to absorb urine or menstrual blood.

[0003] Currently, when diapers and pull-ups are worn, the area around the spine (tailbone) and the back of the sanitary product do not fit tightly. There is a gap between the area around the tailbone and the sanitary product. When the body is lying down and urinating, the liquid can easily leak from the gap between the tailbone and the sanitary product, resulting in back leakage. This greatly affects the user experience of the sanitary product. Utility Model Content

[0004] The present invention aims to provide a structure and sanitary products that prevent back leakage, so as to solve the problem of back leakage in sanitary products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a back leakage prevention structure, including a crotch area, wherein a lifting part is fixedly provided on the inner rear side of the crotch area.

[0006] To achieve the above objectives, the present invention also adopts the following technical solution: a sanitary product, including a trouser body, wherein the trouser body is provided with a back leakage prevention structure as described in this application.

[0007] The principle and advantages of the above-mentioned solution in this application are as follows: The inventor of this application designed an anti-leakage structure and applied it to sanitary products. When the sanitary product is worn, by pulling the lifting part upward, the lifting part causes the inner side of the back of the sanitary product's crotch (the back of the crotch refers to the part of the sanitary product close to the buttocks, and the inner side refers to the side that is in contact with the skin) to fit tightly against the buttocks or the area around the tailbone. This reduces the gap between the buttocks (or the area around the tailbone) and the back of the sanitary product's crotch, which helps to reduce the occurrence of back leakage and greatly improves the comfort of using the sanitary product.

[0008] Preferably, as an improvement, the inner rear side of the crotch is provided with a close-fitting part, one end of which is fixedly connected to the inner rear side of the crotch, and the other end of which is fixedly connected to the lifting part.

[0009] Therefore, the inventors specifically designed a close-fitting section on the inner side of the back of the crotch area. This close-fitting section is designed to adhere to the buttocks and the area around the coccyx. When the sanitary product is worn, pulling the lifting section upwards moves the close-fitting section upwards, ensuring a tight fit between the close-fitting section and the buttocks (or the area around the coccyx) and the back of the crotch area of ​​the sanitary product. This reduces the gap between the buttocks (or the area around the coccyx) and the back of the crotch area of ​​the sanitary product, thus reducing leakage. Compared to having the entire back of the crotch area of ​​the sanitary product directly adhere to the buttocks (or the area around the coccyx of an infant), this specially designed close-fitting section is smaller, easier to operate, and offers better fit and leakage prevention.

[0010] Preferably, as an improvement, the adhesive part is positioned at the rear of the crotch area. Thus, by pulling the lifting part upwards, the lifting part causes the adhesive part to swing at the rear of the crotch area of ​​the sanitary product, thereby making the adhesive part fit against the buttocks (or around the tailbone area).

[0011] Preferably, as an improvement, the side of the lifting part is provided with an adhesive layer for adhering the lifting part to the skin.

[0012] Therefore, an adhesive layer is provided on the lifting part, which adheres the lifting part to the body, thereby keeping the lifting part in an upward lifting state and ensuring the anti-leakage effect of the sanitary product.

[0013] Preferably, as an improvement, the lifting part includes a vertical lifting part and a horizontal lifting part, which are arranged crosswise, and the horizontal lifting part is fixed to the end of the vertical lifting part.

[0014] Therefore, the lifting section adheres to the body, and the horizontal lifting section adheres horizontally to the body. By designing the horizontal lifting section, the adhesion area between the lifting section and the body is increased, making the lifting section more stable and less likely to loosen or fall off, thus ensuring the upward lifting effect. At the same time, the horizontal lifting section's horizontal placement also pulls the vertical lifting section upward, further enhancing the upward lifting effect of the vertical lifting section and improving the anti-leakage effect.

[0015] Preferably, as an improvement, an absorbent layer is fixedly provided on the side wall of the close-fitting part facing the rear of the crotch.

[0016] Therefore, by incorporating an absorbent layer, if a large amount of liquid flows to the contact area, the absorbent layer absorbs the liquid, thereby reducing backflow. Simultaneously, the timely absorption of liquid by the absorbent layer keeps the contact area dry.

[0017] Preferably, as an improvement, a support portion is fixedly provided between the close-fitting portion and the inner side of the rear portion of the crotch.

[0018] Therefore, the support part can raise the close-fitting part, so that the close-fitting part fits tightly against the buttocks (or the area around the tailbone), which helps to reduce the gap between the back of the sanitary product and the buttocks (or the area around the tailbone) and improve the back leakage prevention effect.

[0019] Preferably, as an improvement, one side of the support portion is attached to the inner side of the rear of the crotch, and the other side of the support portion is attached to the close-fitting portion, with the side of the support portion attached to the close-fitting portion being inclined. Thus, the more the support portion is located away from the connection between the close-fitting portion and the rear of the crotch, the greater its thickness, resulting in more effective support for the close-fitting portion and better adhesion between the close-fitting portion and the skin.

[0020] Preferably, as an improvement, the pull-up part extends outside the waistband of the pants. Thus, with the pull-up part located on the outside of the waistband, operations such as pulling up or fastening the pull-up part can be performed from outside the pants without reaching inside, facilitating control of the pull-up part.

[0021] Preferably, as an improvement, the outer surface of the contact portion is provided with a protrusion. Attached Figure Description

[0027] Figure 6 This is a cross-sectional view of the anti-leakage structure in Example 3. Detailed Implementation

[0028] The following detailed description illustrates the specific implementation method:

[0029] The reference numerals in the accompanying drawings include: front waistband 1, back waistband 2, close-fitting part 3, vertical lifting part 4, adhesive layer 5, crotch part 6, horizontal lifting part 7, support part 8, absorbent layer 9, side part 10, and protrusion 11.

[0030] Example 1

[0031] The basics are as follows: Figures 1-3 As shown: This embodiment discloses a sanitary product, which is a diaper or pull-up diaper, suitable for infants or women. Since infants produce more urine than women menstrual blood, existing sanitary products have a higher probability of back leakage when used on infants. Therefore, this embodiment uses an infant as an example for explanation. The sanitary product includes a pant body with a front waistband 1, a back waistband 2, and a back leakage prevention structure. The front waistband 1 is for contact with the abdomen, and the back waistband 2 is for contact with the back of the waist.

[0032] One embodiment of the anti-leakage structure includes a crotch 6. A lifting part is fixed (e.g., integrally molded, adhesively bonded, or sewn) on the inner side of the rear part (the part opposite to the buttocks) of the crotch 6. In this embodiment, the lifting part is specifically a vertical lifting part 4, which is made of non-woven fabric.

[0033] Therefore, when the sanitary product is worn, by pulling up the vertical lifting part 4, the vertical lifting part 4 pulls the back part of the crotch 6, making the back part of the crotch 6 fit tightly against the buttocks (or the area around the tailbone), thereby reducing the gap between the back part of the crotch 6 and the buttocks (or the area around the tailbone). Liquid is less likely to leak from the back part of the crotch 6 and the buttocks (or the area around the tailbone), thus preventing liquid leakage and greatly improving the comfort of using the sanitary product.

[0034] In this embodiment, to further improve the anti-leakage effect, a tight-fitting part 3 is provided on the inner rear side of the crotch 6. In this embodiment, the tight-fitting part 3 is made of non-woven fabric, consistent with the surface material of the sanitary product. The tight-fitting part 3 is sheet-shaped, and its width (in the width direction of the crotch) is 5-10 cm. One end of the tight-fitting part 3 is fixedly connected to the inner rear side of the crotch 6 (e.g., bonded, integrally set, or sewn; in this embodiment, integral setting is preferred). The other end of the tight-fitting part 3 is fixedly connected to the vertical lifting part 4 (e.g., bonded, integrally set, or sewn; in this embodiment, integral setting is preferred). Since only one end of the tight-fitting part 3 is fixed to the surface of the crotch 6, the tight-fitting part 3 can be swung around the rear of the crotch 6, meaning the gap between the tight-fitting part 3 and the inner rear side of the crotch 6 can be changed. Figure 3 As shown, in order to improve the connection stability between the close-fitting part 3 and the rear part of the crotch part 6, and to prevent the close-fitting part 3 from tilting during the lifting process of the vertical lifting part 4, in this embodiment, the left and right sides of the close-fitting part 3 are fixedly connected to the surface layer of the rear part of the crotch part 6 with side parts 10 (e.g., integrally molded, bonded, or sewn; in this embodiment, integral molding is preferred). The side parts 10 are made of non-woven fabric and can shrink. Under the pulling of the vertical lifting part 4, the close-fitting part 3 drives the side parts 10 to stretch flat. Figure 3The middle side portion 10 is in an extended flat state. In this embodiment, the side of the vertical lifting portion 4 is fixedly provided with an adhesive layer 5 for adhering the vertical lifting portion 4 to the skin. The adhesive layer 5 is adhesive, and in order to protect the adhesive layer 5, release paper (not shown in the figure) is attached to the surface of the adhesive layer 5.

[0035] Combination Figure 2 As shown, in this embodiment, the vertical lifting part 4 extends to the outside of the waistband of the pants.

[0036] The specific implementation process is as follows: Wear the sanitary product, peel off the release paper on the adhesive layer 5 of the vertical lifting part 4 to expose the adhesive layer 5, and then pull the vertical lifting part 4 upwards. The vertical lifting part 4 pulls the close-fitting part 3 upwards, moving the close-fitting part 3 away from the inner side of the rear of the crotch 6. The close-fitting part 3 is in close contact with the baby's buttocks, and then the lifting part is attached to the baby's skin. In this embodiment, the close-fitting part 3 is in close contact with the baby's buttocks (or around the baby's tailbone area), thereby reducing the gap between the baby's buttocks (or around the baby's tailbone area) and the rear of the crotch 6 of the sanitary product, reducing the leakage of liquid.

[0037] Example 2

[0038] Combination Figures 4-5 As shown, this embodiment is a further improvement on embodiment 1. In this embodiment, the lifting part includes not only the vertical lifting part 4 but also the horizontal lifting part 7. The horizontal lifting part 7 is located at the end of the vertical lifting part 4, and the horizontal lifting part 7 and the vertical lifting part 4 are arranged intersectingly. The horizontal lifting part 7 is fixed (e.g., integrally molded, glued, or sewn; in this embodiment, integral molding is preferred) to the end of the vertical lifting part 4. In this embodiment, an adhesive layer 5 is also provided on the side of the horizontal lifting part 7, and release paper is adhered to the adhesive layer 5.

[0039] Combination Figure 5 As shown, the lifting part is attached to the body. The horizontal lifting part 7 is horizontally attached to the body, and the vertical lifting part 4 is vertically attached to the body. Compared with Example 1, this embodiment increases the bonding area between the lifting part and the body, making the lifting part more stable and less prone to falling off, thus ensuring the anti-leakage effect of the sanitary product. At the same time, the horizontal lifting part 7 has an upward lifting effect on the vertical lifting part 4, giving the vertical lifting part 4 an upward pulling force, ensuring that the inner side of the rear of the crotch 6 (or the close-fitting part 3) fits tightly to the back of the buttocks (or around the coccyx) and is not prone to loosening.

[0040] Example 3

[0041] Combination Figure 6As shown, this embodiment further defines the features based on embodiments 1-2. In this embodiment, an absorbent layer 9 is fixed (e.g., glued or sewn) to the side wall of the close-fitting part 3 facing the rear of the crotch part 6. The absorbent layer 9 is made of cotton or the material of the existing absorbent core in the crotch part 6 (but thinner than the absorbent core in the crotch part 6), and the thickness of the absorbent layer 9 is 1-2 mm. Therefore, when the close-fitting part 3 is in close contact with the buttocks (or around the tailbone), if there is a large amount of liquid flowing towards the close-fitting part 3, the absorbent layer 9 can fully absorb the liquid, thereby reducing back leakage. After the liquid is absorbed by the absorbent layer 9, there is less liquid remaining on the close-fitting part 3, and at the same time, it can ensure that the close-fitting part 3 is dry when in contact with the skin.

[0042] In other embodiments, to further improve the fit between the close-fitting part 3 and the buttocks (or around the coccyx) and reduce gaps, a support part 8 is fixed (e.g., glued or sewn) between the close-fitting part 3 and the inner rear side of the crotch part 6. In this embodiment, the support part 8 is a block-shaped structure made of sponge, rubber, or cotton. One side of the support part 8 is attached to the inner rear side of the crotch part 6, and the other side of the support part 8 is attached to the close-fitting part 3. The side of the support part 8 attached to the close-fitting part 3 is inclined, and the side profile of the support part 8 in this embodiment is triangular.

[0043] Therefore, when this sanitary product is worn, the support part 8 fills the gap between the close-fitting part 3 and the inner side of the back of the crotch part 6. Under the expansion and support of the support part 8, the close-fitting part 3 fits the skin better and will not leak.

[0044] Example 4

[0045] This embodiment is a further optimization based on embodiments 1-3, combined with... Figure 3 As shown, in this embodiment, a protrusion 11 is provided on the surface of the close-fitting part 3. When the sanitary product is worn, by lifting the close-fitting part 3, the close-fitting part 3 fits against the back of the buttocks. Since the protrusion 11 protrudes from the surface of the close-fitting part 3, the protrusion 11 can further fill the gap between the close-fitting part 3 and the buttocks (or around the coccyx), thereby greatly reducing the gap between the sanitary product and the buttocks (or around the coccyx). This avoids the skin depth in the middle part of the buttocks (or around the coccyx) being too large, which would prevent the close-fitting part 3 from fitting tightly against the skin in the middle part of the buttocks (or around the coccyx), thus greatly preventing the occurrence of back leakage.

[0046] The protrusion 11 can be in the shape of a strip or a block, and it can be regular or irregular. It can fill the gap between the skin of the close-fitting part 3 and the skin of the buttock (or around the coccyx) with a large degree of depression.

[0047] For the protrusion 11, its surface layer can be integrally formed with the close-fitting part 3. The surface layer of the protrusion 11 is made of non-woven fabric, and the interior of the protrusion 11 can be filled with wood pulp fiber, cotton, cloth or other fluffy materials.
