Detailed Description

The leakage-proof adult diaper of the present invention will be clearly and completely explained with reference to the accompanying drawings.

In the description of the present invention, it is to be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the scope of the invention.

As shown in fig. 1 to 3, the utility model provides a leakproof adult diaper, which comprises a surface layer 1, an absorption core layer 2 and a leakproof bottom layer 3 which are sequentially bonded from top to bottom; the surface layer 1, the absorption core layer 2 and the leakage-proof bottom layer 3 are sequentially bonded by a hot melt adhesive bonding process to form an integral structure, which is the prior art and is not described herein again.

Wherein, surface course 1 adopts hydrophilic non-woven fabrics to make, and it has good ventilative and water permeability, can permeate urine to absorption sandwich layer 2 fast, can not absorbed by itself moreover, and then makes surface course 1 can remain dry throughout, avoids the skin of user's private department to be in the moist environment for a long time and causes the eczema. In addition, an oval depression 11 is pressed out from the middle part of the surface layer 1 by a mechanical indentation technology, and drainage holes 12 are uniformly distributed at the bottom of the oval depression 11. In the using process, the oval groove faces the private part of a user, so that urine can quickly permeate into the absorption core layer 2 through the drainage hole 12 in the middle of the oval groove, and the urine is prevented from diffusing to two sides or the rear end of the diaper to cause side leakage or rear leakage.

Urine is absorbed the locking by absorption sandwich layer 2 after surface course 1 permeates absorption sandwich layer 2, and is specific, absorption sandwich layer 2 adopts polymer water-absorbing resin to make, and it has superstrong water absorption and water-locking ability, can avoid the urine to take place to return and ooze. In addition, the surface of the absorption core layer 2 is provided with annular corrugated bulges 21, the annular corrugated bulges 21 are diffused from the center of the absorption core layer 2 to the two ends of the absorption core layer, the annular corrugated bulges 21 are bulges pressed out from the bottom of the absorption core layer 2 upwards through a mechanical indentation technology, high-molecular water-absorbent resin is filled in the bulges, and finally the bulges are fixed on the surface of the absorption core layer 2 through a sewing technology. By arranging the annular corrugated bulges 21 on the surface of the absorption core layer 2, on one hand, a certain gap is formed between the surface layer 1 and the absorption core layer 2, so that the air circulation can be accelerated, and the private part can be kept dry; on the other hand, the annular corrugated bulges 21 can slow down the flow speed of urine to the rear end and the two sides of the diaper, so that the urine can be fully absorbed by the absorption core layer 2, and the occurrence of back leakage or side leakage is avoided.

In addition, a layer of wood-color bamboo pulp paper 4 is clamped between the absorption core layer 2 and the surface layer 1, so that urine permeation can be accelerated, peculiar smell at private parts can be removed, and the paper is not bleached and is safer to use.

The leak-proof bottom layer 3 is used for preventing urine from permeating into the bedding, is made of water-repellent non-woven fabric, and has good air permeability and waterproof permeability, so that the whole air permeability of the diaper can be improved while the urine is prevented from permeating. The back of the leakproof bottom layer 3 is bonded with a back adhesive, so that the diaper can be bonded on underwear to avoid sliding in the using process.

In addition, two elastic connecting belts 5 which are parallel to each other are bonded in the middle of one side of the leakage-proof bottom layer 3, a magnet piece 6 is bonded at one end of the back surface of each elastic connecting belt 5, which is far away from the leakage-proof bottom layer 3, and the magnet piece 6 is bonded at the back surface of the other side of the leakage-proof bottom layer 3. When in use, the diaper is adhered to underwear, and the magnet piece 6 on the elastic connecting belt 5 and the magnet piece 6 on the back of the leakage-proof bottom layer 3 are mutually adsorbed, thereby further preventing the diaper from sliding in the use process. Through setting up elastic connection band 5 and magnet piece 6 to can further improve the fixity of diaper, prevent that it from taking place to slide in the use, reduce the chance that takes place the side leakage or leak after, and then reach the leak protection purpose.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
