Be described in detail below with reference to first embodiment of accompanying drawing absorbent commodity according to the present invention.
The specific embodiment
Fig. 1 is the plane graph as the sanitary towel of first embodiment of the present invention's absorbent commodity; Fig. 2 is the plane graph of major part of the sanitary towel of Fig. 1; And Fig. 3 is the sectional view along the I-I line of Fig. 2
As shown in Figure 1, comprise the non-skin contact surface of the skin contact surface P of liquid permeability, non-liquid permeability according to the absorbent commodity (sanitary towel) 10 of this embodiment and be arranged on skin contact surface P and non-skin contact surface between absorber A.This absorbent commodity 10 is substantially shaped as the configuration of straight strip.
More specifically, skin contact surface P is formed by liquid permeability top layer material 12, and non-skin contact surface is formed by non-liquid permeability backsheet.Top layer material 12 and backsheet are along bonding together at relative place, end limit on the longitudinal direction of sanitary towel 10.
The relative left side of top layer material 12 and backsheet and right edge part broad ways stretch out, and form flap 14,14 thus.Binding agent is coated on the surface of backsheet of flap 14,14, forms standing part 14a, 14a thus.Standing part 14a, 14a protect with (not shown) such as strippable paper, peelable films respectively.
Said structure is identical with conventional absorbent commodity.Binding agent for the material that forms top layer material 12 and backsheet, formation standing part 14a, 14a can use any known respective material, and without any restriction.
As shown in Figure 1, absorbent commodity 10 comprise a pair of before groove 15 behind 16,16 and one of the grooves, groove 16,16 longitudinal directions along sanitary towel 10 are formed on the skin contact surface P of the part 10a (being designated hereinafter simply as " contact portion 10a ") that contacts the discharge portion branch before described, the body fluid of described contact discharge section contact wearer when dressing is discharged the position, and described back groove 15 is formed on when dressing after the contact wearer on the skin contact surface P among the rear portion 10b of side along the width of sanitary towel 10.Distance between the rear end of the decline 15a of back groove 15 and absorber A is 10-50mm, a pair of before the distance W of groove 16,16 between the inside part on the width of sanitary towel 10 1Than the distance W of back groove 15 between the part of the outermost on the width of sanitary towel 10 2Short.
Distance L is necessary for 10-50mm, is preferably 10-30mm.If distance L is shorter than 10mm, the absorbable body fluid volume in groove rear side place will become too small, and the anxiety that can not be absorbed body A absorption and leakage from absorbent commodity 1 from back groove 15 body fluid moving to backflow and that leak is probably arranged.On the contrary, if distance L surpasses 50mm, the tension that becomes of the distance between back groove 15 and drain position probably has too much body fluid and flows among the groove 15 of back, and consequently body fluid flows through the back groove and at an easy rate to backflow.
More specifically, in sanitary towel 10 according to the present embodiment, back groove 15 comprises rear portion 15b and a counter-lateral quadrents 15c, 15c, described rear portion 15b forms bow shape in the rear end of the width upper edge of sanitary towel 10 absorber A, and described sidepiece 15c, 15c are extended forward by rear portion 15b straight line along vertical side edge of sanitary towel 10.
Back groove 15 and preceding groove 16 are preferably 1-10mm, more preferably 3-8mm on depth D.If the depth D of back groove 15 and preceding groove 16 is lower than 1mm, then be difficult to reach the effect of blocking mobile from the teeth outwards body fluid.On the contrary, if depth D surpasses 10mm, will bring the sensation that has some setbacks to wearer.
Be formed with the thickness T of partly locating of back groove 15 in sanitary towel 10 1With the thickness T of partly locating that does not form groove 2Ratio T 1/ T 2Be preferably 0.05-0.7, more preferably 0.1-0.5.
If T 1/ T 2Ratio be lower than 0.05, be T then having preferred thickness 2(the thickness T of sanitary towel 10 2Be preferably 1.5-15mm, more preferably 2-10mm) sanitary towel 10 on formed back groove 15 and preceding groove at 16,16 o'clock by compacting, back groove 15 and preceding groove 16,16 are just too stiff, reduced sometimes paste appropriate.On the contrary, if T 1/ T 2Ratio be higher than 0.7, the mobile effect of fully blocking the body fluid in absorber then is difficult to reach.
The preferred structure of groove below will be described.
Shown in Fig. 2 and 3, back groove 15 forms by groove processing, wherein, a plurality of along the predetermined discontinuous formation of configuration by the recessed rhombus minor groove 15d of skin contact surface P side, and also the zone between two contiguous minor groove 15d, the 15d also is recessed into by skin contact surface P.Like this, back groove 15 has the two rank degree of depth, promptly dark recessed minor groove part and the more shallow zone between two minor grooves.Because recessed below skin contact surface P continuously with the regional such two kinds of degree of depth between minor groove 15d and two adjacent minor groove 15d, the 15d, back groove 15 can have depth D, and keeps the high resiliency of trench portions simultaneously, so helps pasting suitable property.The area of minor groove 15d is preferably 1-100mm 2If this area is less than 1mm 2, the effect of blocking body fluid is just insufficient.On the contrary, if the area of each minor groove 15d greater than 100mm 2, then be difficult to the elasticity that reaches favourable.The spacing of minor groove 15d is preferably 0.5-5mm.If spacing less than 0.5mm, then is difficult to obtain favourable elasticity and contacts with the good of skin.On the contrary, if spacing greater than 5mm, then forms the non-re-entrant zone between two contiguous minor groove 15d, 15d, consequently reduced leakageresistance.
In the groove processing of discontinuous formation minor groove 15d, from the angle of the comfort of the performance of blocking body fluid and wearing, the thickness T of the location of sanitary towel 10 between two contiguous minor groove 15d 3Thickness T with the location that does not form groove 2Ratio T 3/ T 2Be preferably 0.2-0.8, more preferably 0.3-0.6.
From the angle of the comfort of the performance of blocking body fluid and wearing, sanitary towel 10 is in the thickness T of the location that does not form minor groove 15d 1And the thickness T of the location between two contiguous minor groove 15d, the 15d 3Ratio T 1/ T 3Be preferably 0.1-0.8, more preferably 0.3-0.7.
In groove processing method, on the thickness direction of sanitary towel, push the sanitary towel that also hot pressing does not have groove with dandy roll with rhombus embossing spill and predetermined temperature by the skin contact surface side.
Groove 16,16 inwardly forms the arc of convex from the relatively vertically side edge of sanitary towel 10 before a pair of, and in plane graph, they are horizontal symmetry mutually.Pro-groove 16,16 is along the distance W between the inside part on the width of sanitary towel 10 1Be 20-50mm.Distance W 1Than back groove 15 along the distance W between the outermost on the width of sanitary towel 10 part 2Short.
This is to preceding groove the 16, the 16th, forms by the groove processing identical with back groove 15.
Before groove 16,16 link to each other with the front end of two lateral section 15c, 15c of back groove 15 respectively.Consequently, preceding groove 16,16 and back groove 15 are made the as a whole single successive groove that forms.
Before be formed with among the preferred depth D, sanitary towel of groove 16,16 before groove 16,16 like this thickness at part place and the thickness that does not have the groove office preferred than, preferred groove processing method all with after groove 15 identical.
Absorber A can constitute with paper pulp, paper, non-woven fabrics and the super-absorbent polymer of the absorber that is commonly used to form absorbent commodity.From forming and keep the angle of back groove 15 and preceding groove 16,16 more reliably, the preferred material that comprises thermoplastic fibre that uses.
Preferably, thermoplastic fibre is interconnective in absorbent sheet 3, this is the shape that can keep absorbent sheet 13 because of thermoplastic fibre when absorb body fluids, sanitary towel's 10 preferred forms in use can be maintained, and absorbent sheet 13 can be returned to original state after removing pressure, thereby keep sanitary towel, and do not produce distortion with stable manner.
Thermoplastic fibre is had no particular limits, as long as fiber is together adhered to one another when heating.Particularly, preferably use polyethylene fibre, polypropylene fibre, polyester fiber, polyethylene/polyester conjugate fiber, polypropylene/polyester conjugate fiber etc. as thermoplastic fibre.Equally also preferably use vinal etc. at the fiber that is dissolved in hot water and can is easy to bond together when dry.
Can only form absorbent sheet 13 by thermoplastic fibre, also available heat Plasitc fibers and hydrophilic fibre such as fluffed pulp and man-made cellulose fibers, and form with the mixture of known super-absorbent polymer.When using mixture, the combined amount of thermoplastic fibre is preferably the 1-30% of the weight of whole absorbent sheet 13.
When dressing and use, the same according to the sanitary towel 10 of the present embodiment with the sanitary towel of routine, contact portion 10a is placed on zone (in the lower limb fork) between two lower limbs.
