Abstract

The utility model provides an improved absorbing article comprising a permeable surface layer and an impermeable bottom layer which are connected into a whole by the periphery and absorbers arranged between the permeable surface layer and the impermeable bottom layer. The absorbers comprise absorbing cores enwrapped in non-woven fabrics and provided with a plurality of through holes penetrating though the upper surfaces and the lower surfaces of the absorbing cores; the absorbers are positioned in the through holes of the absorbing cores; and the non-woven fabrics on the upper surfaces of the absorbing cores are fixedly connected with the non-woven fabrics on the lower surfaces of the absorbing cores. The improved absorbing article is provided with thin or ultrathin absorbers which are free from agglomeration, rupture and other bad situations after absorbing liquid.

Description

A kind of modified form absorbing articles

Technical field

This utility model relates to a kind of modified form absorbing articles, belongs to hygiene article sector.

Background technology

Disposable adsorption object such as baby paper diaper have been known, it comprises liquid permeability surface layer, absorber and the opaque liquid bottom that from top to bottom sets gradually, described diaper have along the waistline direction extend laterally and by front waist region to the back waist region direction extend 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 left and right sides waist, prevents to come off when left and right sides waist pastes on the waist that can be fixed on diaper the wearer when being fixedly arranged on the frontal waist plaster both lateral sides respectively.The inventor investigates discovery, and known various absorbing articles have towards more and more thinner direction direction and develop, and the thickness of absorbing articles depends primarily on the thickness of absorber.In known absorbing articles, the research staff of this area once repaid the adding proportion of trying to increase super water-absorbing resins, reduce the consumption of paper oar fiber, though thin type that makes thus or ultra-thin absorber liquid absorption do not descend, but absorber globality after imbibition is poor, in wearer's bipod motor process, unfavorable situations such as absorber conglomeration, fracture often appear.

The utility model content

The purpose of this utility model provides a kind of modified form absorbing articles, and described absorbing articles has thin type or ultrafine absorber, unfavorable situations such as conglomeration, fracture can not take place after this absorber imbibition.

The technical scheme that this utility model adopted is such: a kind of modified form absorbing articles, comprise liquid permeability surface layer, the opaque liquid bottom that week links to each other along one and be located between the two absorber, described absorber is made up of the absorbent cores of non-woven fabrics parcel, described absorbent cores is provided with the through hole of a plurality of its upper and lower surfaces of perforation, be positioned at each through hole of absorbent cores, the non-woven fabrics of described absorbent cores upper surface and the non-woven fabrics of lower surface are affixed mutually.

Above-mentioned modified form absorbing articles, described each through hole is the matrix arrangement along the surface of absorbent cores.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: since the levels non-woven fabrics to be positioned at each absorbent cores through hole affixed mutually, thereby absorber globality after imbibition is improved, absorbent cores unfavorable situations such as fracture, conglomeration can not occur, can increase the adding proportion of super water-absorbing resins in the absorbent cores like this, thereby produce thinner absorbent cores.

The specific embodiment

With reference to figure 1, Fig. 2 and Fig. 3, embodiment one discloses a kind of ultra-thin diaper, and it from top to bottom comprises successively: liquid permeability surface layer, absorber and opaque liquid bottom, wherein:

Described liquid permeability surface layer is made up of hydrophilic nonwoven fabrics 1 and the hydrophobic nonwoven 2 that is fixedly arranged on hydrophilic nonwoven fabrics 1 both lateral sides edge respectively, the inboard of described two hydrophobic nonwoven 2 extends to form free margins along the mid portion to hydrophilic nonwoven fabrics 1, described free margins is provided with the elastic 3 of anti-side leakage, described absorber is made up of the absorbent cores 43 of upper strata non-woven fabrics 41 and lower floor's non-woven fabrics 42 parcels, be distributed with six through holes 431 on the described absorbent cores 43, described six through holes 431 rectangular array in absorbent cores 43, at these six through hole 431 places, described upper strata non-woven fabrics 41 is bonding mutually with lower floor's non-woven fabrics 42, for this reason, the adding proportion of described super water-absorbing resins in whole absorbent cores 43 can reach 40% even more, this kind absorbent cores is unlikely to take place conglomeration or fracture because the levels non-woven fabrics of each through hole is mutual affixed after having absorbed urine, thereby under the prerequisite that guarantees identical liquid absorption, it is minimum that thickness reduces to.Described opaque liquid bottom is made up of ventilative but fluid-tight mylar 5 and the hydrophobic nonwoven 6 of being located at mylar 5 outsides, the both lateral sides of described hydrophobic nonwoven 6 and two hydrophobic nonwoven 2 outsides are along affixed respectively, vertical both sides of described liquid permeability surface layer are along affixed with mylar 5 respectively, and between the described hydrophilic nonwoven fabrics 1 at the vertical two ends of diaper and mylar 5, be respectively equipped with waistline tightness band 7, between the described hydrophobic nonwoven 2 of diaper both lateral sides and mylar 5, be respectively equipped with the lower limb that extends along the longitudinal direction and enclose elastic 8, the front waist region of described diaper is positioned at hydrophobic nonwoven 6 outsides and is provided with frontal waist plaster 9 in addition, the both lateral sides that the back waist region of described diaper is positioned at hydrophobic nonwoven 6 is provided with left and right sides waist and pastes 10 and be used for respectively can discharging affixedly with frontal waist plaster 9, increases the diffusion velocity of urines in diaper so be provided with water conservancy diversion layer 11 between described in addition hydrophilic nonwoven fabrics 1 and the absorber.

With reference to figure 4, embodiment two has done partial improvement to absorber on the basis of embodiment one, be that the arrangement mode that absorbent cores 43 ' goes up each through hole 431 ' changes, when non-woven fabrics wrap up this absorbent cores 43 ' and each through hole 431 ' locate mutually affixed after, each through hole 431 ' of described absorbent cores 43 ' can prevent that absorbent cores from producing conglomeration, fracture after absorb body fluids on the one hand, can in the imbibition process, play guide functions on the other hand, thereby the diaper that comprises this kind absorber have better absorption and diffusion effect.

Claims

1, a kind of modified form absorbing articles, comprise liquid permeability surface layer, the opaque liquid bottom that week links to each other along one and be located between the two absorber, it is characterized in that: described absorber is made up of the absorbent cores of non-woven fabrics parcel, described absorbent cores is provided with the through hole of a plurality of its upper and lower surfaces of perforation, be positioned at each through hole of absorbent cores, the non-woven fabrics of described absorbent cores upper surface and the non-woven fabrics of lower surface are affixed mutually.
