Description
Technical field
This utility model relates to a kind of sanitary towel, relate in particular to a kind of menses that can make and ooze down fast, and effectively prevent side leakage, the speed that leaks the back oozes leakproof sanitary towel.
Background technology
The sanitary towel of various sizes and shape is widely used in by the women and absorbs menstruation and other kenosis.Along with development of times, people, use the basic demand comfortable, that absorbability is good except requiring sanitary towel to satisfy also in continuous variation the use idea of sanitary towel, and are also more and more higher to the requirement of the leakproof of sanitary towel, permeability.But leak anti-side leakage, back is the difficult problem that sanitary napkin manufacture manufacturer needs to be resolved hurrily always.The main cause that side leakage, back leakage appear in sanitary towel has: one, when blood volume is big, skew has appearred because of the problem of sanitary towel's absorbent properties or when using sanitary towel, make absorber not have alignment liquid to discharge the position, thereby cause menses to fail in effective time, all to be absorbed, thereby residual menses or other liquid laterally or vertically flow on towel body surface, cause side leakage, back to leak; Two, after menses or other liquid are absorbed fully, in absorber, still be in liquid condition, because the variation of human body attitude, especially human body be in seat, during the posture that crouches, compressing because of the human body body weight, make to absorb that intravital menses or other liquid are squeezed and laterally, vertically flow, ooze out and form side leakage, back leakage from the joint of absorber and towel body end envelope.
As everyone knows, become known technology by top layer, the fluid-tight bottom of porous and the sanitary towel that wick constituted that is clipped between two-layer, in order to improve the moisture pick-up properties of sanitary towel, prevent that sanitary towel from producing menses because of hygroscopic capacity is not enough and leaking outside, most sanitary towels have added hydroscopic high-molecular resin again in wick.This macromolecular material all is that the wick shaping stage in the sanitary napkin manufacture flow process divides at random in the shaping hub and is sprinkling upon in the wick, and its distributed areas drawn game in the wick partly amount of spreading is irregular.Macromolecular material is when having improved sanitary towel's hygroscopic capacity, its disorder distribution has brought many hidden danger for the normal use of sanitary towel: the macromolecular material on close permeable top layer is after imbibition, will certainly influence the following of follow-up menses and ooze, thereby cause menses to produce leakage in towel body surface horizontal mobility; The fiber of formation wick is different in size because of its fiber, orientation is mixed and disorderly, therefore menses flowing in wick originally is irregular, high molecular branch spreads the uneven lack of uniformity that menses absorb in the wick that then can strengthen, and causes the wick regional area because of the saturated seepage that occurs that absorbs water.
In existing technology, provide the solution of multiple anti-side leakage for this reason.The sanitary napkin that China utility model patent ZL99118836 announces in inside, sanitary towel top layer, is installed with the elastomeric element of elongation state towards the longitudinal direction extension, and the surface element of sanitary napkin is swelled upward.And, by the surface layer extruding inwardly of surface layer and inner core is formed along the groove of longitudinal direction extension, thereby prevent the side leakage of menses in the both sides of sanitary napkin.Above-mentioned known sanitary towel, though the flexible surface element of sanitary towel that makes by sanitary towel's top layer inner elastomeric parts swells upward, thereby make that sanitary towel and user contact skin are tight, but this elastomeric element also makes and has produced separated space between the surface layer of sanitary towel and the wick simultaneously, thereby reduced menses and oozed the effect that is absorbed by inner core from the top layer fast down, in addition because this elastomeric element is the material of hygroscopicity difference makes, it is installed in sanitary towel's top layer inner face, will certainly hinder the following of menses and ooze.
Sanitary towel as the patent No. 96120164.9 is announced by extending the inner indent with high and low compacting ditch of compacting in the wick both sides by its length direction, suppresses horizontal diffusion of menses and leakage.Because constituting the entity of above-mentioned indent is the plasticity liquid sucting fiber, when when blood volume is big, menses also can expand towards the indent athwartship plane by capillarity simultaneously and ooze not only along the diffusion of indent length direction, thereby cause the horizontal side leakage of menses.
Also has a kind of sanltary towel that prevents side leakage, be to have increased one deck U type leakproof PE film in liquid-tight outer inboard, though this U type leakproof PE film has solved menses be absorbed after, be subjected to human body body weight extruding back again and the horizontal leakage problem that produces, fail to prevent to leak thereafter problem.Because described U type leakproof PE film is to close shape with three side sealing absorber is wrapped up, therefore be unfavorable for the volatilization (especially in the winter time) of menses steam in the absorber simultaneously, can bring moist uncomfortable sensation to user.
The sanitary towel that the patent No. 00215435.8 is announced, by be shaped in sanitary towel's surface pressure horizontal stroke (indulging) to U or the recessed road of V-type prevent lateral leakage of menstrual blood; By being set, a protuberance and a human body anal cleft tight connecting that is formed by ellipsoid of elasticity prevent that menses from falling to leak at towel body afterbody simultaneously.But there is following defective in this sanitary towel:
1. suppress edge, recessed road along this sanitary towel's lateral surfaces and overlap with towel body two outer ledges,, flow into menses in this recessed road and in a single day can not infiltrate fully will continue in the towel body and produce side leakage to towel body two side flow along recessed road when when blood volume is big.2. because the entity in the above-mentioned recessed road of formation is the plasticity liquid sucting fiber, when when blood volume is big, menses expand towards the indent athwartship plane by capillarity simultaneously and ooze not only along the diffusion of indent length direction, thereby cause the horizontal side leakage of menses.3. this sanitary towel prevents that by a protuberance and a human body anal cleft tight connecting that is formed by ellipsoid of elasticity menses from falling to leak, this patent is not described the ellipsoid of elasticity material of described formation protuberance, as this ellipsoid is that non-absorbent material constitutes, then this sanitary towel prevents to leak behind the menses by the compactness that described protuberance and human body anal cleft are fitted, it has higher requirement to the position that sanitary towel fits on underwear, in case sanitary towel and human body relative position change, will cause this protuberance and anal cleft place generation gap and leakage occur down; Constitute if this ellipsoid is a hygroscopic materials, when when blood volume is big, close in case this ridge moisture absorption is full, menses still can expand seepage flow from the ridge edge and go out and produce down leakage.4. when human body is in seat, during the posture that crouches, because of the compressing of human body body weight, can make that still absorbing intravital menses is squeezed and produces horizontal stroke (indulge) to flowing, and oozes out and form side (back) leakage from the joint that absorber and towel body end seal.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of can make that menses ooze down fast, isostatic thin stream, lock is inhaled fully, and prevents that effectively the speed that leak side leakage, back from oozing leakproof sanitary towel.
In order to solve the problems of the technologies described above, this utility model is by the following technical solutions: this utility model speed is oozed leakproof sanitary towel and is longitudinal, comprise: but the top layer of a transflective liquid, an impenetrable liquid but can gas-pervious bottom, a absorbent article core between described top layer and described bottom; Also be included between described top layer and the absorbent article core water conservancy diversion layer of forming by hydrophobic material that extends towards longitudinal direction with elongation state and the lock pool in described absorbent article core.
Preferably, described absorbent article core comprises inside and outside two moisture absorption layers, and outer moisture absorption layer wraps up the inner moisture absorbing layer sealing along main longitudinal centre line.
Preferably, described lock pool is concentrated by lock water macromolecular material and is distributed in the bottom of inner moisture absorbing layer and forms, and the ratio range of the thickness in this lock pool and interior absorbent article core thickness is 0.3～1.
Preferably, also be included in described absorbent article core both sides and respectively prolong the U type first that the coated a slice of main longitudinal axis centrage symmetry is made up of the permeable watertight material and refuse water cloth, and this first is refused water cloth and grow with absorbent article core is same.
Preferably, also be included in described being coated in the zone of refusing to overlap with outer rim around the described water conservancy diversion layer between the water cloth in first of absorbent article core both sides, be suppressed with the extruding groove that extends along the extruding groove and the transverse direction of sanitary towel's longitudinal direction extension.
Preferably, also be included in towel and hold described top layer upper surface to stick one deck after one's death second to refuse water cloth by what the permeable watertight material was formed, this second refuse water cloth stiff end and sanitary towel towel at one's side edge overlap, and its along towel body direction length between 35～50mm.
Preferably, also be included in towel and hold a vertical central uplift after one's death towards top layer.
