Description

Technical Field

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

[0002] Chinese Patent Publication No. CN221490434U discloses a leak-proof diaper, comprising a waterproof bottom film, a first absorbent core, strip-shaped pleats, a second absorbent core, a water-soluble film, and a third absorbent core. The first absorbent core and the strip-shaped pleats are both disposed on the waterproof bottom film. The second absorbent core is disposed on the strip-shaped pleats. The water-soluble film covers the openings of the strip-shaped pleats. A space for urine flow is formed between the second absorbent core and the water-soluble film. The third absorbent core is disposed on the left and right sides of the waterproof bottom film. The surface of the third absorbent core is wrapped with a waterproof film, and the third absorbent core is connected to the second absorbent core. The diaper is provided with the first absorbent core, the second absorbent core, and the third absorbent core.

[0003] This invention improves the absorbency of diapers by using a first absorbent core, a second absorbent core, and a third absorbent core to prevent leakage. When the diaper is used at night, the urine will be directed to the back area of ​​the diaper first. When the volume is large, the urine cannot be completely absorbed when it flows to the back waistband, and will flow out of the diaper from the back waistband, causing leakage, or spreading to the back waistband and wetting the bedding. Utility Model Content

[0004] Therefore, in order to address the above problems, this utility model provides a leak-proof diaper, which solves the problem that urine leaks out at the back waist or wets the bedding due to design defects in existing diapers.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A leak-proof diaper includes a diaper body with a front waist area corresponding to the front of the waist, a back waist area corresponding to the back of the waist, and a connecting area connecting the front waist area and the back waist area. The back waist area has an elastic back waistband with several elastic strips inside. A leak-proof waist patch is located on the side of the elastic back waistband closest to the skin. The leak-proof waist patch has an overlapping area that overlaps with the elastic back waistband and extends towards the connecting area. Leak-proof bands are located on both sides of the connecting area, with both ends of each leak-proof band extending towards the front waist area and the back waist area. The ends of the leak-proof bands are located below the leak-proof waist patch.

[0007] Furthermore, each of the leak-proof strips includes at least one leak-proof sheet and one leak-proof elastic strip, with the leak-proof elastic strip disposed on the inner side of each leak-proof sheet.

[0008] Furthermore, each of the leak-proof strips includes a leak-proof sheet, and the inner side of each leak-proof sheet is folded inward to wrap around each of the leak-proof elastic strips.

[0009] Furthermore, the overlapping area is provided with several embossed patterns.

[0010] Furthermore, each of the embossed patterns consists of spaced-apart dots.

[0011] Furthermore, the overlapping area extends 1-3 cm towards the connecting area.

[0012] Furthermore, at least one notch is provided on the front waist area, and the notch is located on the side of the front waist area away from the connecting area.

[0013] Furthermore, a notch is provided on the front waist area, and the notch is centrally located.

[0014] Furthermore, the length of the leak-proof waist patch is 220-300mm, and the width of the leak-proof waist patch is 40-60mm.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention combines an elastic back waistband with a leak-proof waist patch in the lower back area. When lying flat at night, the urine output is high. Because the part of the leak-proof waist patch extending into the connecting area is not combined with the back waistband, the urine directed to the lower back area is blocked between the leak-proof waist patch and the connecting area. In addition, under the elastic contraction of the elastic back waistband, the part of the leak-proof waist patch extending into the connecting area will form a wavy edge, which increases the amount of urine that the leak-proof waist patch can block.

[0028] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] Example

[0030] like Figures 1 to 3 As shown, a leak-proof diaper includes a diaper body 1. The diaper body 1 has a front waist area 2 corresponding to the front of the human waist, a back waist area 3 corresponding to the back of the human waist, and a connecting area 4 connecting the front waist area 2 and the back waist area 3. The back waist area 3 has an elastic back waistband 5, and the elastic back waistband 5 has a plurality of elastic back waist strips 51. The side of the elastic back waistband 5 closest to the human skin has a leak-proof waist patch 6, and the leak-proof waist patch 6 has an overlapping area 61. The overlapping area 61 and the elastic back waist patch 61 are connected to the elastic back waistband 3. The waist belt 5 overlaps, and the overlapping area 61 extends towards the connecting area 4 by 3cm. The connecting area 4 has leak-proof strips 7 on both sides, and the two ends of each leak-proof strip 7 extend towards the front waist area 2 and the back waist area 3. The end of the leak-proof strip 7 is located below the leak-proof waist patch 6. The leak-proof waist patch is 250mm long and 50mm wide. Specifically, the end of the leak-proof strip 7 is located below the elastic back waist belt 5.

[0031] Under the elastic contraction of the elastic back waistband 5, the portion of the leak-proof waist patch 6 extending towards the connecting area 4 will form a wavy edge, increasing the amount of urine that the leak-proof waist patch 6 can block. Furthermore, since the end of the leak-proof band 7 is located below the leak-proof waist patch 6, after wearing, the extended area of ​​the leak-proof waist patch 6 will be lifted up by the leak-proof band 7. Since the extended area of ​​the leak-proof waist patch 6 is not in the back waist area 3, it will not be squeezed and will not adhere to the connecting area 4, thus blocking the urine directed to the back waist area 3 between the leak-proof waist patch 6 and the connecting area 4.

[0032] Each of the leak-proof strips 7 includes at least one leak-proof sheet 71 and one leak-proof elastic strip 72, with each leak-proof elastic strip 72 disposed inside the leak-proof sheet 71; in this embodiment, each of the leak-proof strips 7 includes one leak-proof sheet 71, with the inner side of each leak-proof sheet 71 folded inward to wrap around each leak-proof elastic strip 72, wherein the leak-proof elastic strip 72 is disposed in the connecting area 4.

[0033] Both the elastic strip 51 and the leak-proof elastic strip 72 are made of elastic bands, which can be purchased on the market and will not be described in detail here.

[0034] The overlapping area 61 is provided with a plurality of embossed patterns 62. In this embodiment, the embossed patterns 62 are two lines, the embossed patterns 62 are straight lines, and the embossed patterns 62 are composed of a plurality of spaced dot-like discontinuities. The embossed patterns 62 can fix the leak-proof waist patch 6 to the elastic back waistband 5, reduce the use of spray adhesive, and ensure the breathability of the back waist area 3. In other preferred embodiments, the embossed patterns can also be wavy.

[0035] At least one notch 21 is provided on the front waist area 2. The notch 21 is located on the side of the front waist area 2 away from the connecting area 4. At least one notch 21 is centrally located. The notch 21 can reduce the feeling of constriction on the waist and improve comfort.

[0036] In this embodiment, a notch 21 is provided on the front waist area 2. The notch 21 is centrally located to avoid scratching the navel. In other preferred embodiments, three notches 21 are provided on the front waist area 2.

[0037] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
