Abstract

The utility model relates to a disposable moisture absorption article, in particular to a back-leak proof sanitary napkin. The sanitary napkin comprises a surface layer, a bottom film and an absorption core body located between the surface layer and the bottom film, wherein the surface layer, the bottom film and the absorption core body are pressed into a whole body, and a strip groove is arranged on the rear portion of the absorption core body. The strip groove is arranged on the rear portion of the absorption core body, so that the liquid absorption capacity and downward infiltration rate are increased, the back leakage is reduced as much as possible, simultaneously, the deformation folds of the sanitary napkin due to activity of the user are reduced, furthermore, the friction of the deformation-generated folds on the using part of the skin is reduced, and the comfort of the user is improved.

Description

The sanitary towel that leak a kind of anti-back

Technical field

This utility model relates to a kind of disposable absorbent article, is specifically related to a kind of sanitary towel.

Background technology

Sanitary towel can be divided into front portion, pars intermedia and rear portion, and anterior positive towards human body, the rear portion is towards the human body back side, and the middle part is between front and rear.Existing sanitary towel generally comprises surface layer, counterdie, the absorptive core between surface layer and counterdie and is fixedly arranged on the flap of the sanitary towel absorptive core left and right sides respectively.This sanitary towel is fixed on the underwear through the adhesion agent on counterdie and the flap, and this adhesion agent generally is sprayed on the vertical mid portion of sanitary towel, and its adhesive is generally not strong, and is therefore just very limited to the location of sanitary towel.When user is movable, sanitary towel's distortion that is distorted easily, the fold that distortion the forms use position that can rub lets user not feel well; Because sanitary towel's distortion can not absorb liquid effectively, prevents liquid infiltration, causes trouble and embarrassment to user.

Summary of the invention

To the problems referred to above that prior art exists, the technical problem that this utility model solves is: when increasing the absorbtivity of sanitary towel, when user is movable, reduce sanitary towel's torsional deformation as much as possible, reduce the back simultaneously and leak; For solving this technical problem this utility model a kind of good absorbing effect is provided, reduces the back leakage, and sanitary towel not yielding, distortion.

This utility model is achieved in that the sanitary towel that leak a kind of anti-back, comprises surface layer, counterdie and the absorptive core between surface layer and counterdie, and said surface layer, counterdie and absorptive core are pressed into one, and said absorptive core rear portion is provided with strip groove.

Further, said absorptive core is made up of dustless ply of paper and absorbent paper layer, between this dustless ply of paper and absorbent paper layer, is provided with to be positioned at sanitary towel's pars intermedia center convex body, and absorbent paper layer is between dustless ply of paper and counterdie; Absorptive core be width from the front portion to the rear portion, broaden gradually trapezoidal.

Further, said absorptive core is provided with ventilative through hole.

Advantage with respect to prior art: be provided with strip groove at the absorptive core rear portion; Liquid Absorption amount and following infiltration rate degree have been increased; And reduced back leakage as much as possible, simultaneously, reduced because of the user activity causes sanitary towel and be out of shape fold; And then the fold that has reduced the distortion generation has improved the comfort level of user to using the friction of position skin.

Description of drawings

Fig. 1-this utility model structural representation.

Among the figure, 1-absorptive core, 2-both wings, 3-through hole, 4-center convex body, 5-strip groove.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is done further explain.

Referring to Fig. 1, the sanitary towel that leak a kind of anti-back of this utility model comprises surface layer, counterdie and the absorptive core between surface layer and counterdie 1, and said surface layer, counterdie and absorptive core 1 are pressed into one, and said absorptive core 1 rear portion is provided with strip groove 5.This strip groove 5 has increased Liquid Absorption amount and following infiltration rate degree; And reduced back leakage as much as possible, simultaneously, reduced because of the user activity causes sanitary towel and be out of shape fold; And then the fold that has reduced the distortion generation has improved the comfort level of user to using the friction of position skin.

Further, said strip groove 5 has certain radian, the human buttock's that fits more camber line.

Said absorptive core 1 is made up of dustless ply of paper and absorbent paper layer, between this dustless ply of paper and absorbent paper layer, is provided with to be positioned at sanitary towel's pars intermedia center convex body 4, and absorbent paper layer is between dustless ply of paper and counterdie.Absorptive core 1 be designed to two-layer with have only one deck to compare to have increased absorbtivity, absorbent paper layer makes the liquid of absorption be difficult for bleeding back between dustless ply of paper and counterdie.The center convex body 4 women's perineum part of just in time fitting, when user was movable, center convex body 4 combined to locate sanitary towel better with adhesion agent on counterdie and the both wings, and then minimizing sanitary towel is out of shape, and had also increased absorbtivity simultaneously, had prevented that liquid from spilling.

What further, absorptive core 1 broadened from the front portion to the rear portion for width gradually is trapezoidal.This shape is used the shape at position more near human body, ergonomic has reduced the anterior friction with the inboard skin of thigh root of sanitary towel when user is movable, has improved the comfort level of user.

On absorptive core 1, be provided with ventilative through hole 3, not only increased the following infiltration rate degree and the absorbtivity of liquid, and strengthened breathability, reduce allow liquids.This lets user use that position and subenvironment of surface layer formation keep dry, salubrious state, has improved the comfort level of user, has lowered the probability of breed bacteria.

The surface layer of sanitary towel contacts with human body, counterdie and underwear adhesion, surface layer and counterdie broaden gradually from the front portion to the rear portion for width trapezoidal, both wings 2 are one with said surface layer and counterdie, and are formed at sanitary towel's pars intermedia.Preferably, both wings 2 are formed at the forward position of sanitary towel's pars intermedia, make the sanitary towel's long part of a part part that is positioned at both wings 2 both sides short.

Spary has binding agent on counterdie and the both wings 2, the release paper that adhesion one deck tears easily on the binding agent, and during use, user tears release paper, is bonded on the underwear sanitary towel fixing.In this application, binding agent is a PUR.

Said non-wiping sanitary towel length is 240mm ~ 280mm, and the absorptive core 1 width width at narrow place is 55mm ~ 65mm, and width the widest part width is 85mm ~ 95mm, and two sides of absorptive core 1 are 4 ° ~ 5 ° with the vertical angle of vertical line.

Sanitary towel's core body 1 shape that leak said anti-back both had been applicable to daily-use sanitary towel, also was applicable to overnight hygienic band.

Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation this utility model; Although with reference to preferred embodiment this utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of this utility model; And not breaking away from the aim and the scope of this utility model technical scheme, it all should be encompassed in the middle of the claim scope of this utility model.
