Description

A kind of air permeable sanitary towel

Technical field

The utility model relates to hygiene article sectors, more specifically, it relates to a kind of air permeable sanitary towel.

Background technique

Sanitary napkin is the required product in women physiological period, and in reality, female friend is often in physiology phase Inside for various reasons menses are leaked, causes clothing or sheet, coverlet contaminated, it is difficult to wash away.

Traditional sanitary napkin includes sanitary napkin ontology and flap, and sanitary napkin ontology includes waterproof layer, water absorption layer, surface layer, is inhaled Water layer is evenly distributed in the surface layer of sanitary napkin ontology between waterproof layer and surface layer and prevents bleeding back hole, and the anti-hole that bleeds back is back taper Shape hole.

But for above-mentioned traditional sanitary napkin, since waterproof layer and water absorption layer directly pass through hot melt fitting and surface layer It is bonded between water absorption layer also by hot melt, so as to cause the poor air permeability of the sanitary napkin, is easy to influence usage comfort.

Utility model content

In view of the deficienciess of the prior art, being improved whole the purpose of this utility model is to provide a kind of air permeable sanitary towel The gas permeability and usage comfort of body.

To achieve the above object, the utility model provides following technical solution:

A kind of air permeable sanitary towel, including ontology and flap, ontology from bottom to top include waterproof layer, water absorption layer and face Layer, water absorption layer offer hollow gas-permeable channels, and gas-permeable channels and water absorption layer are horizontally disposed, and the inner wall of gas-permeable channels is provided with First breathable waterproof membrane, surface layer offer the first air hole, and the first air hole passes through water absorption layer and communicates with gas-permeable channels, first Air permeable waterproof block is filled in air hole.

By adopting the above technical scheme, by setting gas-permeable channels, the first breathable waterproof membrane is set in gas-permeable channels, thus Convenient between gas-permeable channels and water absorption layer air circulation with exchange, to improve the gas permeability of water absorption layer；It is ventilative by being arranged Water-proof block not only reduces menses and enters the general of gas-permeable channels to pass air through air permeable waterproof block and enter in gas-permeable channels Rate, and convenient for gas-permeable channels and extraneous air exchange, to improve whole gas permeability, and then improve usage comfort.

Further, air permeable waterproof block extends the first air hole far from one end of gas-permeable channels.

By adopting the above technical scheme, when using the sanitary napkin, one end for extending the first air hole of air permeable waterproof block It is abutted with skin, i.e., there are gaps between the top surface and skin of sanitary napkin, consequently facilitating health is through the sky between surface and skin Air-flow is logical, improves air permeability effect.

Further, the hemispherical setting in the one end of air permeable waterproof block far from gas-permeable channels.

By adopting the above technical scheme, air permeable waterproof block extends the hemispherical setting in one end of the first air hole, to subtract The contact area of few air permeable waterproof block and skin.

Further, the bottom of air permeable waterproof block is fixed with elastomer block, and elastomer block is set in gas-permeable channels.

By adopting the above technical scheme, by the way that elastomer block is arranged, when sanitary napkin and skin relatively move, extruded elastomeric layer, Relatively move air permeable waterproof block with air hole, to accelerate the flowing velocity of air in gas-permeable channels；And in elastic layer Deformation process in, so that the abutment of air permeable waterproof block and skin is changed, to reduce viscous on the skin general of sanitary napkin Rate improves the salubrious degree of skin.

Further, elastomer block is offered along perforative first impenetrating mouth of saturating first air hole depth direction, and elastomer block is also It offers along perforative second impenetrating mouth of gas-permeable channels extending direction.

By adopting the above technical scheme, by the way that the first impenetrating mouth is arranged, convenient for sanitary napkin outside air and ventilative duct in Air exchange；By the way that the second impenetrating mouth is arranged, consequently facilitating the air circulation in gas-permeable channels, improves whole gas permeability.

Further, surface layer top surface is provided with bulge loop, and bulge loop is arranged in a ring and surrounds gas-permeable channels.

By adopting the above technical scheme, by the way that bulge loop is arranged, so that the effect of blocking is played to the diffusion of menses, to rise The effect of leakproof is arrived.

Further, surface layer top surface offers several drainage troughs along the setting of surface layer length direction, the setting of the first air hole On the outside of drainage trough.

By adopting the above technical scheme, it by the way that drainage trough is arranged, is flowed into drainage trough in surface layer convenient for menses, and to health The both ends of towel are spread, and convenient for seeping under menses, and then improve the effect of leakproof, while air moves in drainage trough, are improved ventilative Effect.

Further, several antibacterial particles are provided in gas-permeable channels.

By adopting the above technical scheme, by the way that antibacterial particle is arranged, to play sterilization, antibacterial to the bacterium in hollow cavity Effect.

Compared with prior art, the utility model has the advantages that:

(1) by setting air permeable waterproof block and gas-permeable channels, consequently facilitating the air between gas-permeable channels and water absorption layer It circulates and exchanges, gas-permeable channels and extraneous air exchange to improve whole gas permeability, and then improve usage comfort；

(2) one end for extending the first air hole of air permeable waterproof block is abutted with skin, i.e. the top surface of sanitary napkin and skin Between there are gap, convenient for health through the air circulation between surface and skin, improve air permeability effect；

(3) in the deformation process of elastic layer, the abutment of air permeable waterproof block and skin is made to change, is defended to reduce The raw viscous probability on the skin of towel, improves the salubrious degree of skin.
