Abstract
Description
Technical Field
[0001] The utility model relates to the field of diapers, in particular to a leak-proof structure for the edge of a diaper. Background Art
[0002] Diapers are commonly used daily necessities for babies. A good-quality diaper can keep a baby sleeping soundly throughout the night. When a baby urinates or defecates, the diaper absorbs urine or feces. Currently, although diapers can absorb a baby's urine, most of them have the problem of side leakage at the edges. If there is a large amount of liquid in a short period of time, the liquid flows to both sides, easily causing liquid to leak out. The leaked liquid flows onto the baby's clothes and the bed, increasing the trouble of cleaning. Therefore, there is an urgent need to develop a leak-proof structure for the edge of a diaper that can multi-block urine, prevent urine from leaking from the side edges of the diaper, and improve the leak-proof seal of the diaper. Summary of the Utility Model
[0003] In order to overcome the problem that most existing diapers have side leakage at the edges, and if there is a large amount of liquid in a short period of time, the liquid flows to both sides, easily causing liquid to leak out, the technical problem to be solved by the utility model is to provide a leak-proof structure for the edge of a diaper that can multi-block urine, prevent urine from leaking from the side edges of the diaper, and improve the leak-proof seal of the diaper.
[0004] The utility model is achieved by the following specific technical means:
[0005] A leak-proof structure for the edge of a diaper includes a diaper main body; a front waist circumference is fixedly arranged on the front side of the diaper main body, and a front waist sticker is fixedly arranged on the outer side of the front waist circumference; an elastic rear waist circumference is fixedly arranged on the rear side of the diaper main body, and first magic tapes are respectively fixedly arranged on the left and right sides of the elastic rear waist circumference; an absorbent core body is fixedly arranged in the middle of the inner surface of the diaper main body; three-dimensional leak-proof partition edges are respectively fixedly arranged on both sides of the absorbent core body arranged in the middle of the inner surface of the diaper main body; curling edges are respectively fixedly arranged on the left and right sides of the diaper main body.
[0006] A leak-proof strip for preventing urine leakage is also fixedly arranged on the inner surface of the curling edges arranged on the left and right sides of the diaper main body; the leak-proof strip includes a blocking strip, the blocking strip is a rectangular sheet structure, and the side close to the three-dimensional leak-proof partition edge is fixedly bonded to the inner surface of the curling edge arranged on the diaper main body; one end of the blocking strip close to the curling edge arranged on the diaper main body is also provided with an adhesive part fixedly connected to the blocking strip; a second magic tape for bonding with the adhesive part is also fixedly arranged at one end of the blocking strip away from the pasting part; a convex strip is also fixedly arranged on the side of the blocking strip away from the curling edge arranged on the diaper main body.
[0007] Furthermore, the blocking strip is made of hydrophobic non-woven fabric; it has a good waterproof effect and prevents urine from penetrating the blocking strip and leaking outwards.
[0008] Furthermore, an elastic band is provided inside the barrier strip; after wearing, the barrier strip can closely fit the skin of the wearer to form a seal, ensuring the leakage prevention effect.
[0009] Furthermore, the convex strip is made of silicone material; it has good elasticity and waterproofness, closely fits the skin of the wearer to achieve a seal and leakage prevention effect, and at the same time has a soft touch to ensure the wearing comfort of the diaper.
[0010] Furthermore, the convex strip is a circular arc-shaped protrusion; it increases the tightness and comfort of fitting with the skin of the wearer.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The utility model achieves multiple blockages of urine, prevents urine from leaking from the side edges of the diaper, and increases the leakage prevention and sealing performance of the diaper.
[0013] Through the set three-dimensional leakage prevention side edge and leakage prevention strip, multiple blockages are carried out on urine to prevent urine from leaking from the side edges of the diaper, and the leakage prevention and sealing performance of the diaper is increased. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following further describes the utility model with reference to the drawings: Embodiment
[0018] A diaper edge leakage prevention structure, as Figure 1-2 shown, includes a diaper main body 1; a front waist circumference 2 is fixedly arranged on the front side of the diaper main body 1, and a front waist sticker 4 is fixedly arranged on the outer side of the front waist circumference 2; an elastic rear waist circumference 3 is fixedly arranged on the rear side of the diaper main body 1, and first magic tapes 5 are respectively fixedly arranged on the left and right sides of the elastic rear waist circumference 3; an absorbent core 6 is fixedly arranged at the middle of the inner surface of the diaper main body 1; three-dimensional leakage prevention side edges 7 are respectively fixedly arranged on both sides of the absorbent core 6 arranged at the middle of the inner surface of the diaper main body 1; rolled edges 8 are also respectively fixedly arranged on the left and right sides of the diaper main body 1;
[0019] On the inner surface of the curled edges 8 provided on both left and right sides of the diaper main body 1, a leak-proof strip 9 for preventing urine leakage is fixedly provided; the leak-proof strip 9 includes a retaining strip 91, the retaining strip 91 is a rectangular sheet-like structure, and is fixedly bonded to the inner surface of the curled edge 8 provided on the diaper main body close to the three-dimensional leak-proof border 7; one end of the retaining strip 91 close to the curled edge 8 of the diaper main body 1 is also provided with an adhesive part fixedly connected to the retaining strip 91; at the end of the retaining strip 91 far from the adhesive part 92, a second magic tape 93 for bonding with the adhesive part is fixedly provided; on the side of the retaining strip 91 far from the curled edge 8 of the diaper main body 1, a convex strip 94 is fixedly provided.
[0020] Working principle:
[0021] When using the diaper of the present utility model, it is worn by pasting the first magic tape 5 on the elastic rear waistband 3 with the front waist patch 4 on the front waistband 2; subsequently, the second magic tape 93 on the leak-proof strip 9 at the curled edge 8 of the diaper main body 1 is bonded to the adhesive part on the leak-proof strip 9, and at the same time, the tightness is adjusted so that the leak-proof strip 9 forms a sealed leg guard around the thigh root.
[0022] During use, most of the excreted urine will be directly absorbed by the absorbent core 6 of the diaper main body 1, and some of the liquid will flow to the side. Three-dimensional leak-proof borders 7 are provided on both sides of the absorbent core 6, which can continue to block the urine and prevent the urine from flowing outwards, so that the liquid is directly absorbed by the absorbent core 6 of the diaper; when a large amount of liquid surges in at the same time, causing some urine to flow outwards through the three-dimensional leak-proof border 7, a leak-proof strip 9 is provided on the curled edge 8 of the diaper main body 1. The leak-proof strip 9 can form a sealed leg guard around the thigh root, closely fitting with the skin of the wearer, and can continue to block the urine to prevent the urine from flowing outwards continuously; by providing the three-dimensional leak-proof border 7 and the leak-proof strip 9 to block the urine multiple times, it is possible to prevent the urine from leaking from the side edge of the diaper, increasing the leak-proof seal of the diaper.
[0023] Although the present disclosure has been described in detail with reference to exemplary embodiments, the present disclosure is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes can be made without departing from the scope of the present disclosure.
