Description

Disposable absorbent article with a comfortable leak-proof barrier

Technical field:

The utility model relates to the technical field of daily necessities, in particular to disposable absorbent articles such as diapers, sanitary napkins and incontinence pads.

Background technique:

Infants and other incontinent persons are often required to wear absorbent articles such as diapers and the like in order to receive and contain urine and other body exudates. The function of the absorbent article is to receive and contain the excrement, isolate the excrement from the wearer's body and isolate the excrement from the wearer's pants or bed sheets.

The traditional disposable absorbent articles commonly used, such as sanitary napkins, are generally flat with wings, which are more suitable for use when the normal flow rate is normal, but when the flow rate is large in a short time, the absorption of the towel body often occurs not in time. At this time, the liquid will quickly spread from the middle absorption area to both sides. Although there are wings, it cannot prevent the liquid from leaking to both sides. Especially when the flaps are folded and attached to the bottom of the underpants during use, the liquid is more likely to leak from the connecting portion of the flaps and the surface layer facing the liquid discharge site to dirty the underpants. At the same time, when the wings are folded and attached to the bottom of the underwear, an angle will be formed. The surface layer at this angle directly contacts the human skin, and the human body will feel uncomfortable when using it. Skin-to-skin contact is more frictional and more likely to cause discomfort. In addition, when the human body is in a sleeping state, it can only keep lying on its back to avoid side leakage, but people who are accustomed to lying on their sides cannot keep lying on their backs all night, and they cannot avoid this phenomenon by turning over unconsciously when they are asleep.

In order to avoid the occurrence of the above situation as much as possible, sanitary napkins with protective edges on both longitudinal sides also appear on the market at present, but the existing protective edges are all directly erected from the wings and folded into the absorption area of the towel body Yes, so in normal use, the protective edge does not stand on the sensitive part as expected to act as a barrier, but instead presses the absorbent area of the sanitary napkin, causing liquid to leak to both sides of the napkin body. Moreover, the current protective edge is set wider, so that it will not only be pressed to the absorption area during use, but also cause discomfort due to the large area in contact with the human body, especially in the season of wearing thin clothing. Sanitary napkins not only make people feel stuffy, but are also very easy to reveal, so that they cannot wear clothes that fit and show their figure during the wearing time; Sexual absorbent articles also have similar defects.

In view of the lack and inconvenience of the above-mentioned conventional disposable absorbent articles, the applicant has developed a disposable absorbent with a comfortable leak-proof partition by adhering to the spirit of research, innovation and excellence, and using his professional vision and expertise. thing.

The utility model relates to a disposable absorbent article with a comfortable leak-proof partition, which includes a liquid-permeable surface layer 1 , a liquid-impermeable bottom layer 4 and an absorbent core 2 that can absorb and hold liquid between the surface layer 1 and the bottom layer 4; wherein, at least the left and right side edges of the absorbent core 2 are formed with The leak-proof partition 6 of the absorption area A, the leak-proof partition 6 is formed by the upward protrusion of the absorbent core 2 and the corresponding parts of the surface layer 1, and contacts the human skin with the raised top surface of the surface layer 1.

When in use, the top surface of the leak-proof partition 6 (that is, the raised top surface of the surface layer 1) contacts the skin of the human body, making it comfortable to wear. When there is a short-term large flow, the liquid will quickly spread from the central absorption area A to the left and right sides, or even the front and rear sides; when the liquid flows to the two sides, it can be blocked by the leak-proof partition to prevent the back seepage from penetrating into the absorbent core 2. It is then absorbed by the absorbent core 2, so it can more effectively prevent side leakage and side seepage.
