Reverse-osmosis-preventing paper diaper

Technical Field

The utility model relates to the field of sanitary articles, concretely relates to prevent paper diaper that oozes conversely.

Background

Diapers are disposable products. Is made of materials such as non-woven fabrics, toilet paper, fluff pulp, high polymer water-absorbing resin, PE films, rubber bands and the like. Because the traditional diaper is frequently changed, the cleaning amount is large, the skin of a baby is not noticed slightly, the baby is easy to soak in urine stains and feces stains, the cleaning and airing conditions are not good, and bacteria are easy to breed. The disposable diaper is convenient to carry, does not need to be cleaned, and is convenient to replace, but the existing diaper often has the problem of urine reverse osmosis due to the defects of structural design, and if the replacement is not timely, the skin of a baby is easily stimulated, and the phenomenon of 'red buttocks' is easily caused.

Chinese patent No. 201620853318.9 discloses an anti-reverse osmosis panty-shape diapers, include from last to down adhesive surface course, water conservancy diversion layer, core, waterproof layer and bottom in proper order, wherein the surface course be hydrophilic SSS non-woven fabrics, the water conservancy diversion layer is made by hydrophilic spunbonded nonwoven, the core includes to make the utricule and hug closely the hot-blast cloth of this utricule internal surface upside and the pearl that absorbs water of filling in the utricule by hydrophilic SMS non-woven fabrics, the waterproof layer is the polyethylene ventilated membrane, the bottom is hydrophilic SSS non-woven fabrics, and the panty-shape diapers of this structure mainly play through the heat-seal cloth of surface course and prevent reverse osmosis effect, and the effect of preventing reverse osmosis is comparatively limited.

SUMMERY OF THE UTILITY MODEL

Therefore, to the above problem, the utility model provides a prevent paper diaper that oozes, solve prior art's paper diaper and take place to ooze easily and make baby's skin receive amazing problem.

In order to achieve the purpose, the utility model is realized by the following technical proposal: an anti-reverse-osmosis paper diaper comprises a liquid-permeable surface layer, a liquid-impermeable bottom layer and an absorber arranged between the liquid-permeable surface layer and the liquid-impermeable bottom layer which are integrally connected along the periphery, wherein the paper diaper is defined to have a longitudinal direction along the length direction and a transverse direction along the width direction, the absorber is provided with more than two grooves extending along the longitudinal direction, the absorber is provided with a wood pulp layer, the thickness of the wood pulp layer is 1/5-1/3 of the thickness of the absorber, a flow guide layer is arranged between the wood pulp layer and the liquid-permeable surface layer, a high molecular water-absorbing resin layer is arranged below the absorber, the thickness of the high molecular water-absorbing resin layer is 2 times of that of the wood pulp layer, the macromolecule water-absorbing resin layer is provided with a second groove from the bottom to the top, the opening width of the second groove is smaller than the width of the bottom of the groove, the thickness of the second groove is 1/3-1/2 of the thickness of the high polymer water-absorbent resin layer.

The further improvement is that: the liquid-permeable surface layer is divided into an upper area, a middle area and a lower area which are sequentially connected along the longitudinal direction, and the middle area is uniformly provided with embossing grooves.

The further improvement is that: the two grooves on the absorber are symmetrically distributed along the longitudinal direction.

The further improvement is that: the grooves are V-shaped grooves, and the depth of the grooves is 1/2-2/3 of the thickness of the absorber.

By adopting the technical scheme, the beneficial effects of the utility model are that: the utility model discloses an anti-reverse osmosis panty-shape diapers, its absorber is provided with more than two grooves extending along the longitudinal direction, the arrangement of the groove can accelerate the liquid to seep downwards, and further, the groove is V-shaped, which can make the liquid reverse osmosis amount small, a wood pulp layer is arranged on the absorber, the wood pulp layer expands after absorbing the liquid, when the liquid absorption amount is increased, the volume is enlarged after expanding, the liquid can be further prevented from upwards reverse osmosis; set up the polymer absorbent resin layer below the absorber, the polymer absorbent resin layer has high water absorption lock water ability, and upwards offers the second recess in the bottom of polymer absorbent resin layer, second recess opening width is less than the width of tank bottom, can further prevent that liquid from upwards reverse osmosis.

Detailed Description

The following detailed description will be given with reference to specific embodiments, so as to solve the technical problems by applying technical means, and to fully understand and implement the technical effects of the present invention.

The embodiment of the utility model is that:

referring to fig. 1 to 3, an anti-reverse osmosis paper diaper comprises a liquid-permeable surface layer 1, a liquid-impermeable bottom layer 3 and an absorber 2 arranged between the two, wherein the liquid-permeable surface layer 1 is divided into an upper region 11, a middle region 12 and a lower region 13 which are connected in sequence along the longitudinal direction, the middle region 12 is uniformly provided with a circular embossing groove 14, the liquid-impermeable bottom layer is composed of a PE film 31 and a non-woven fabric 32 arranged at the bottom of the PE film 31, the liquid-impermeable bottom layer is defined to have a longitudinal direction along the length direction and a transverse direction along the width direction, the absorber 2 is provided with two grooves 21 which are symmetrically distributed along the longitudinal direction, the grooves 21 are V-shaped grooves, the depth of the grooves 21 is 1/2 of the thickness of the absorber 2, the absorber 2 is provided with a wood pulp layer 4, and the thickness of the wood pulp layer 4 is 1/3 of the thickness of the absorber 2, a flow guide layer 5 is arranged between the wood pulp layer 4 and the liquid permeable surface layer 2, a high polymer water-absorbent resin layer 6 is arranged below the absorber 2, the thickness of the high polymer water-absorbent resin layer 6 is 2 times of that of the wood pulp layer 4, a groove 7 is upwards formed in the high polymer water-absorbent resin layer 6 from the bottom, the opening width of the groove 7 is smaller than that of the bottom of the groove, and the thickness of the groove 7 is 1/2 of the thickness of the high polymer water-absorbent resin layer 6.
