Description

Low reverse osmosis sanitary towel

Technical Field

The utility model relates to a disposable hygienic product field especially relates to a low anti-sanitary towel that oozes.

Background

Sanitary towel is a material that possesses the absorptive capacity, and main material is cotton, non-woven fabrics, the macromolecular polymer and the macromolecular polymer composite paper that paper pulp or above material complex formed, and the design of side mainly is used for preventing the edge leakage, because can present certain angle with the sanitary towel body during the use, more easily with the part of the groin come into touch the friction, consequently the sanitary towel of the side of using soft material is more favored by women.

The sanitary towel is divided into three layers, namely a surface layer, an absorption core and a bottom layer. The back adhesive of the sanitary napkin is a waterproof material, and can retain menstrual blood in the sanitary napkin to absorb the menstrual blood flowing out from the vagina when women have menstrual flow. The female has poor resistance in menstrual period, and various maladies of the body can be caused by careless adjustment.

The most attention of the existing sanitary towel products is the absorbability, so the absorbability is the main innovation point in the aspects of development and publicity. However, the problem of reverse osmosis occurs after the absorbent core absorbs a certain amount of menstrual blood, so that the surface of the sanitary napkin is always kept wet during use, which leads to the defect that bacteria are easy to grow and diseases are caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a sanitary towel with low reverse osmosis, which overcomes the defect that the sanitary towel product in the prior art does not have reverse osmosis prevention effect and leads to the easy breeding of bacteria on the surface of the sanitary towel.

In order to realize the purpose of the utility model, the utility model discloses a following technical scheme realizes:

the utility model provides a low anti-sanitary towel that oozes, it includes the sanitary towel main part, the sanitary towel main part is from last to including compound surface course, absorption core and compound basement membrane down in proper order, compound surface course is from last to including the surface course non-woven fabrics, water-stop film and the dustless paper that bond in proper order down, be provided with the opening on the compound surface course, the opening is the toper, and its aperture that is located surface course non-woven fabrics department is greater than the aperture that is located water-stop film and dustless paper department in proper order.

The utility model provides a low anti-sanitary towel that oozes is provided with the opening at compound surface course, and it can effectively circulate the menses, and the opening is the toper simultaneously, can accelerate the velocity that the menses flows under to from last. And simultaneously, the utility model discloses still be provided with the conical runner hole of one deck water barrier film cooperation at composite surface layer middle part, it can enough make the menstrual blood circulation of top to the absorption core in, can effectively completely cut off again and reverse the menstrual blood that oozes to the surface from the absorption core, consequently can effectively keep composite surface layer's drying to reduce bacterial growing rate, effectively guaranteed that the women private is healthy.

Preferably, the surface of the water-resisting membrane is coated with a super-hydrophilic coating in a grid shape, so that the flow holes are connected in series with each other.

The setting is latticed super hydrophilic coating can carry out the water conservancy diversion to the menses for the menses can circulate to the opening along latticed super hydrophilic coating in, has accelerated the flow and the absorption rate of menses above the water-stop film.

Preferably, the middle part of the composite surface layer is provided with an invagination area, and the horizontal height of the bottom of the invagination area is lower than that of the composite surface layer.

The setting invagination area can carry out certain spacing to the menstrual blood that flows out, prevents the risk of side leakage, has also reduced the area with skin contact simultaneously to stifled hotness has been reduced greatly.

Preferably, the composite surface layer and the absorption core are fixedly bonded through a plurality of adhesive tapes, and a diversion trench is formed between the adjacent adhesive tapes.

Set up the guiding gutter and can make the menses can the fast dispersion when flowing to absorbing the core surface to promote absorption rate, can also evenly absorb the menses on whole absorbing the core in addition, prevent to absorb partly because of the phenomenon that the play of too much absorption menses and lead to sticks together in the core.

Preferably, the side edges of the sanitary napkin main body are also provided with protective wings.

Preferably, the flap back surface is provided with a first adhesive portion.

Preferably, the back surface of the sanitary napkin main body is provided with a plurality of second bonding parts arranged along the length direction of the sanitary napkin main body.

Therefore, the utility model discloses following beneficial effect has:

(1) the utility model can effectively prevent the reverse osmosis of menstrual blood, thereby ensuring that the surface of the sanitary towel keeps dry and comfortable;

(2) the breeding rate of bacteria is reduced, and the health of the female private parts is effectively ensured;

(3) the area of contact with the skin is reduced, thereby greatly reducing the stuffy feeling.
