Detailed Description

The sanitary pad of the present invention will be described in detail 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 and 2, the utility model provides a sanitary pad, it includes from last to lower adhesive surface course 1 in proper order, polymer absorption sandwich layer 2 and prevention of seepage ventilative bottom layer 3, surface course 1, polymer absorption sandwich layer 2 and the adherend of prevention of seepage ventilative bottom layer 3 adopts to refuse water non-woven fabrics 4 to carry out the banding, refuse water non-woven fabrics 4 and form a loop type barricade, because it has the performance that prevents the liquid seepage, therefore can prevent that menstrual blood from taking place the edge leakage or the edge leakage. The left side and the right side of the bottom of the water-repellent non-woven fabric 4 are both bonded with the protective wings 5, the lower surfaces of the protective wings 5 are bonded with the gum 6, and the gum 6 is bonded on underpants when the sanitary napkin is used, so that the sanitary napkin can be fixed. It should be noted that, the above-mentioned bonding and edge sealing both adopt a hot melt adhesive bonding process, which is the prior art and therefore is not described herein in detail.

In this embodiment, in order to improve the air permeability of the sanitary pad, the surface layer 1 is configured to have an i-shaped structure composed of a top hydrophilic nonwoven fabric 11, a bottom hydrophilic nonwoven fabric 12, and an elastic support 13 sandwiched between the top hydrophilic nonwoven fabric 11 and the bottom hydrophilic nonwoven fabric 12; the elastic support body 13 is also fixed between the top hydrophilic non-woven fabric 11 and the bottom hydrophilic non-woven fabric 12 through a hot melt adhesive bonding process, and the elastic support body 13 is uniformly distributed along the length direction of the top hydrophilic non-woven fabric 11 and the bottom hydrophilic non-woven fabric 12.

Wherein both ends tip of the hydrophilic non-woven fabrics 11 of top layer all is equipped with the bleeder vent 111 that supplies the air to pass, just the hydrophilic non-woven fabrics 11 of top layer with the top medial surface bonding of water non-woven fabrics 4 refuses, the hydrophilic non-woven fabrics 12 of bottom layer with the bonding of polymer absorption sandwich layer 2, set up into an air channel 9 that supplies circulation of air between hydrophilic non-woven fabrics 11 of top layer and the hydrophilic non-woven fabrics 12 of bottom layer and the water non-woven fabrics 4 refuses, elastic support body 13 plays the supporting role to air channel 9.

Because the water repellent non-woven fabrics 4 all have good air permeability, in the use, the bleeder vent 111 on the hydrophilic non-woven fabrics 11 of air accessible top layer gets into in the air channel 9, then discharges to the outside air through water repellent non-woven fabrics 4 to accomplish the gas exchange of private department, take away heat and the peculiar smell in the air channel 9 simultaneously, and then improved the holistic gas permeability of panty liner and use comfort. In addition, by using the elastic support body 13 as the support body of the air channel 9, no matter the user stands or sits down, a certain space is provided between the top hydrophilic non-woven fabric 11 and the bottom hydrophilic non-woven fabric 12 for air circulation, so that the sanitary pad has good ventilation effect, and can be used in non-menstrual period.

In particular, in this embodiment, the elastic support body 13 is preferably a cylindrical elastic block, and is made of polyurethane material, so that it has good bending resistance, and has better flexibility and elasticity than other elastic materials, and is easier to bond, thereby improving the use comfort of the user, and is easier to process and produce.

In addition, the hydrophilic non-woven fabrics that adopts in this embodiment is difficult for keeping liquid for the menstrual blood can get into macromolecule absorption sandwich layer 2 through hydrophilic non-woven fabrics fast, and can not absorbed by hydrophilic non-woven fabrics, thereby makes surface course 1 can remain dry and comfortable all the time, thereby can further improve user's use comfort.

Specifically, in this embodiment, a layer of wood-color bamboo pulp paper 7 is bonded between the polymer absorption core layer 2 and the bottom hydrophilic nonwoven fabric 12, which can accelerate the absorption of menstrual blood by permeation, and can effectively remove the odor at the private part, and meanwhile, since the wood-color bamboo pulp paper is not bleached, the use is safer.

Specifically, in this embodiment, the polymeric absorbent core layer 2 is made of a polymeric absorbent resin, which has good water absorption performance, and can condense absorbed menstrual blood to prevent the absorbed menstrual blood from occurring rewet. In addition, as shown in fig. 3, the upper surface of the polymer absorption core layer 2 is provided with a diversion trench 21, the diversion trench 21 is wave-shaped, menstrual blood can flow and diffuse along the diversion trench 21 after flowing to the polymer absorption core layer 2, and meanwhile, the flow speed of the menstrual blood can be slowed down in the flowing process, so that the menstrual blood can be fully absorbed and condensed, and further, the leakage after occurrence is prevented.

Specifically, in this embodiment, the air permeation preventing bottom layer 3 is made of a PE film material, as shown in fig. 4, an anti-slip adhesive tape 8 is adhered to the lower surface thereof, the anti-slip adhesive tape 8 is arranged along the length direction of the air permeation preventing bottom layer 3 in a staggered manner, the anti-slip adhesive tape 8 is made of silica gel, the width of the anti-slip adhesive tape is 1mm, the thickness of the anti-slip adhesive tape is 0.2mm, and the anti-slip adhesive tape is fixed to the lower surface of the air permeation preventing bottom layer 3 by using a hot pressing process, wherein the hot pressing process is the prior art. The anti-slip rubber strip 8 can increase the friction force between the anti-permeation air bottom layer 3 and underwear, so that the sanitary pad can be prevented from moving in the using process, and the side leakage chance is reduced.

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.
