Abstract

The utility model provides a breathable diaper. The breathable 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, wherein the periphery of liquid-permeable surface layer and the periphery of the liquid-impermeable bottom layer are integrally connected. Leakage-proof strips extending in the length direction of the absorber are arranged on the two sides in the transverse direction of the upper surface of an absorption core respectively, all the leakage-proof strips and the absorption core are formed integrally, and the cross section of each leakage-proof strip is of an isosceles trapezoid structure in shape. The absorber is composed of an upper elastic sheet and the lower absorption core coated with hydrophilic non-woven fabric. The upper side faces of all the leakage-proof strips are fixedly connected with the upper elastic sheet. The liquid-impermeable bottom layer is a teflon film layer which is permeable to air but impermeable to liquid, air-permeable micropores are evenly distributed in the teflon film layer, water vapor in an unimolecular state can permeate through the micropores smoothly, but liquid cannot permeate through the micropores.

Description

The gas-permeable paper urine pants

Technical field

This utility model relates to the making of hygienic article, is specifically related to a kind of gas-permeable paper urine pants.

Background technology

Disposable adsorption object has been known as baby paper diaper, it comprises liquid permeability surface layer, absorber and the opaque liquid bottom set gradually from top to bottom, described diaper have along the waistline direction, extend laterally and by front waist region, to the back waist region direction, extended vertically, the front waist region of described diaper is positioned at the opaque liquid bottom outside and is provided with frontal waist plaster, the both lateral sides that is positioned at back waist region is pasted along being provided with the left and right waist, when waist subsides in left and right are fixedly arranged on respectively the frontal waist plaster both lateral sides, can are fixed on diaper on wearer's waist and prevent from coming off.

As Fig. 1, known anti-side leakage absorbent commodity, comprise the liquid permeability surface layer 1 ' set gradually from top to bottom, absorber and opaque liquid bottom 3 ', described absorber is comprised of upper strata non-woven fabrics 21 ' and the absorbent cores 23 ' of lower floor's non-woven fabrics 22 ' parcel, the both lateral sides of the upper surface of described absorbent cores 23 ' is respectively equipped with along the Leakproof strip 24 ' of absorbent cores 23 ' longitudinal extension, the upper side of described each Leakproof strip 24 ' is fixedly connected with described upper strata non-woven fabrics 21 ', described Leakproof strip 24 ' is reeled and is formed by the water wetted material layer, be distributed with water-absorbing resins on the water wetted material layer, the length of described Leakproof strip 24 ' is 50～90% of absorber length, be highly 3～10mm, width is 5～10mm, the upper side of Leakproof strip is fixedly connected with part transverse width with the upper strata non-woven fabrics is 3～10mm.Above-mentioned these gas-permeable paper urine pants are provided with Leakproof strip in the both lateral sides of absorbent cores, Leakproof strip can effectively absorb the liquid to side leakage, thereby effectively stop liquid toward the both sides diffusion, stop the phenomenon of side leakage to occur, but, the inventor finds above-mentioned anti-side leakage absorbent commodity in use, after Leakproof strip has absorbed liquid, its upper surface non-woven fabrics is easy to separate because of the expansion of Leakproof strip with the affixed face of absorbent cores, in wearer's bipod motor process, the absorbent cores conglomeration very easily appears, the unfavorable situations such as fracture, and its Leakproof strip and absorbent cores split arrange, need first to make two Leakproof strips in production process, and then be compound to absorbent cores upper surface both sides, complex manufacturing, cost is high, separately, known anti-side leakage absorbing articles, because the opaque liquid bottom is wanted waterproof and mostly adopted gas impermeable material, the dampness of perspiration and urine, steam can't be discharged fast, thereby baby's hip are easy to produce eczema.

The utility model content

Therefore, for the problems referred to above, this utility model provides that a kind of anti-side leakage is effective, production cost is low, the gas-permeable paper urine pants of gas-permeable, liquid-impermeable.

For achieving the above object, this utility model is achieved through the following technical solutions: the gas-permeable paper urine pants, comprise the liquid permeability surface layer that week is connected along one, opaque liquid bottom and be located at absorber between the two, the upper surface both lateral sides of described absorbent cores is respectively equipped with the Leakproof strip extended along the absorber length direction, described each Leakproof strip and absorbent cores are one-body molded, described Leakproof strip cross section be shaped as isosceles trapezoidal structure, described absorber is comprised of the absorbent cores of upper strata elastic sheet material and lower floor's hydrophilic nonwoven fabrics parcel, the upper side of each described Leakproof strip is fixedly connected with described upper strata elastic sheet material, described opaque liquid bottom is for breathing freely but liquid-tight polytetrafluoroethylene film layer, the water vapour that is evenly equipped with the unimolecule state on described polytetrafluoroethylene film layer can see through smoothly, the ventilative micropore that liquid can't see through.

Further improved: the both sides that are positioned at each Leakproof strip on described absorbent cores are interval with the groove that connects its upper and lower surface along the Leakproof strip length direction, be positioned at each groove place of absorbent cores, upper strata elastic sheet material and lower floor's hydrophilic nonwoven fabrics of described absorber are mutually affixed.

Further improved: as between described liquid permeability surface layer and absorber, to be provided with guide layer.

Further improved: the spacing of two described Leakproof strips is more than or equal to the width of described guide layer.

Further improved: the length of described Leakproof strip is 80% of absorber length, is highly 6mm, and width is 8mm.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this utility model gas-permeable paper urine pants are utilized the elastic stretching performance of upper strata elastic sheet material, after the volume expansion of Leakproof strip absorption liquid, not there will be upper strata elastic sheet material and absorbent cores affixed phenomenon of separating because of the expansion of Leakproof strip, absorbent cores and Leakproof strip are one-body molded, and production cost is low, and Leakproof strip can not produce displacement after imbibition, thereby can spread toward both sides by more effective prevention liquid, stop the phenomenon of side leakage to occur.Described opaque liquid bottom is for breathing freely but fluid-tight polytetrafluoroethylene film layer, be evenly equipped with the ventilative micropore that water vapour can see through smoothly, liquid can't see through of unimolecule state on described polytetrafluoroethylene film layer, make this new disposable absorbing articles guarantee that liquid does not also have good breathability when the opaque liquid bottom appears, dampness, the steam of perspiration and urine can be discharged from the opaque liquid bottom fast, avoid because poisture-penetrability is bad, the phenomenon of the long eczema of hip.
