Description

Disposable absorption article

Technical Field

The utility model relates to a disposable hygienic product technical field especially relates to a disposable absorption articles for use.

Background

With the progress of science and technology, the performance of disposable sanitary products is more and more concerned by people, which is mainly reflected in dryness, comfort and no side leakage. At present, the side leakage condition easily appears in disposable absorption articles, especially when a large amount of liquid gets into the absorption articles simultaneously, the absorption core needs certain space and time to absorb liquid, and when partly liquid got into the absorption core upper surface and absorbs, another part liquid was piled up and is spread in upper direction both sides, leaks from the side easily. Patent application No.: 201721925556.7, discloses a disposable absorbent article, which is easy to diffuse liquid to both sides and to cause side leakage when a large amount of liquid flows in.

SUMMERY OF THE UTILITY MODEL

Therefore, in order to solve the above problems, the present invention provides a disposable absorbent article. Which solves the technical problem that the disposable absorption article is easy to have side leakage.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a disposable absorption article comprises a liquid permeable top layer, an absorption core layer and a leakage-proof bottom layer which are sequentially overlapped from top to bottom, wherein the absorption core layer comprises a first absorption core, a plurality of hydrophilic fiber nets which are horizontally distributed, and a plurality of second absorption cores which are arranged on the hydrophilic fiber nets, the second absorption cores are in a strip shape and are arranged at two sides of the absorption core layer along the length direction, the plurality of second absorption cores are gradually arranged in the absorption core layer in a stepped manner from the outer side to the middle part in a reducing manner at intervals, the top surface of each second absorption core is provided with an arc surface, the arc surface is inclined downwards from the outer side to the inner side, and the first absorption core is arranged below the plurality of second absorption cores; the liquid permeable top layer is provided with bulges along both sides of the length direction.

Further:

the third absorption core is arranged in the bulge, the upper surface of the first absorption core is provided with a groove corresponding to the third absorption core, the third absorption core is arranged above the groove, the height of the bottom surface of the third absorption core is lower than that of the bottom surfaces of the plurality of second absorption cores, and the third absorption core can be inserted into the groove when being pressed down and moved.

The third absorbent core is secured to the liquid-permeable top sheet by stitching.

The hydrophilic fiber net is fixed on the leakage-proof bottom layer through sewing, and the plurality of second absorption cores are fixed on the hydrophilic fiber net through sewing.

By adopting the technical scheme, the beneficial effects of the utility model are that:

(1) the first absorption core and the second absorption core of the utility model can respectively absorb liquid, thereby reducing the volume of the first absorption core; when a large amount of liquid enters the absorbing article at the same time, the plurality of second absorbing cores distributed at intervals in a ladder shape increase the area for absorbing the liquid, so that the liquid has a large amount of space for absorbing and guiding, and the liquid is not easy to diffuse to two sides;

(2) the third absorption core can be inserted into the groove of the first absorption core due to pressure, liquid can be well prevented from flowing out from two sides, the height of the bottom surface of the third absorption core is lower than that of the bottom surfaces of the plurality of second absorption cores, the stepped structure of the plurality of second absorption cores can be well maintained, and the stepped structure of the second absorption cores is prevented from being damaged by extrusion.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 and fig. 2, the present embodiment provides a disposable absorbent article, which includes a liquid permeable top layer 1, an absorbent core layer 2, and a leakproof bottom layer 3, which are sequentially stacked up and down, the absorbent core layer 2 includes a first absorbent core 21, a plurality of hydrophilic fiber nets 24 distributed horizontally, and a plurality of second absorbent cores 22 disposed on the hydrophilic fiber nets 24, the second absorbent cores 22 are in a strip shape and are arranged at two sides of the absorbent core layer 2 along the length direction, the plurality of second absorbent cores 22 are arranged in the absorbent core layer 2 in a step-like manner with gradually decreasing intervals from the outer side to the middle part, the top surface of the second absorbent core 22 is provided with an arc surface 221, the arc surface 221 inclines downwards from the outer side to the inner side, and the first absorbent core 21 is disposed below the plurality of second absorbent cores; the two sides of the liquid permeable top layer 1 along the length direction are respectively provided with a bulge 11, and a third absorption core 23 is arranged in the bulge 11; the upper surface of the first absorption core 21 is provided with a groove 211 corresponding to the third absorption core 23, the third absorption core 23 is arranged above the groove 211, the height of the bottom surface of the third absorption core 23 is lower than that of the plurality of second absorption cores 22, and the third absorption core 23 can be inserted into the groove 211 when being pressed downwards and moved; the hydrophilic fiber net 24 is fixed on the leakproof bottom layer 3 by sewing, and the plurality of second absorption cores 22 are fixed on the hydrophilic fiber net 24 by sewing; the third absorbent core 23 is secured to the liquid-permeable topsheet 1 by sewing
