Pad holder of the present invention presents retractility at least on the width (with the vertical orthogonal direction of pad holder, along trunk direction on every side) of pad holder.On vertical (from the direction of waist peristome) of pad holder, do not need to have retractility, as long as it is just passable to present extensibility towards lower crotch.But, by having retractility (particularly buttocks～dorsal part waist) longitudinally, keeper is followed near the buttocks skin easily because of walking or the stretching, extension that action causes such as sit down of standing, and suppresses the generation of landing easily, so preferably also have retractility in the vertical.In addition, along the irregular complicated shape of abdominal part (particularly advanced age person multilamellar abdomen) or buttocks etc., also be preferred easily from the good this point of fit.
Preferably front portion Lower Half and back portion Lower Half have retractility to pad holder of the present invention at least.Particularly, preferably, the front portion Lower Half of pad holder and back portion Lower Half comprise the retractility parts and constitute to have retractility on the whole.In addition, preferably, pad holder be included in pad holder vertically on have extensibility or retractility, have the Stretchable sheet of retractility in the horizontal and constitute.
The pad holder 1 of the 1st embodiment covers wearer's anterior superior iliac spine 8,8 by front portion 2 as shown in Figure 2 when wearing.In addition, anterior superior iliac spine is the anatomy term, is the projection (part of representing with label 8 among Fig. 5) of the blunt circle that exists at the front end of crista iliaca.Anterior superior iliac spine 8 be present in body surface near, about the wearer, exist a pair of.In Fig. 2, the position of umbilicus is represented with label 10.
On the front portion 2 of pad holder 1, as shown in Figure 1, sidepiece from the width center side of front portion Lower Half 2D to front portion first half 2U is formed with the pair of right and left elongation suppressing portion (the 1st elongation suppressing portion of front portion) 21,22 of the extensibility longitudinally that can suppress pad holder 1 respectively with band shape.The 1st elongation suppressing portion of front portion be formed on the front portion of pad holder, suppress the pad holder part of extensibility longitudinally.As shown in Figure 1, front portion Lower Half 2D is meant the part that is positioned at than the binary straight line L21 of the long L2 of upright crotch of front portion 2 being leaned on the below, and front portion first half 2U is meant and is positioned at the part by the top than this straight line L21.The sidepiece of front portion first half 2U be positioned at front portion first half 2U and when pad holder 1 is worn, be positioned at pair of right and left anterior superior iliac spine 8,8 separately the position or than it by the part outside the width.
The width center side of front portion Lower Half 2D is to be positioned at front portion Lower Half 2D and to be positioned at the part of leaning on width center side (the vertical CL of Central Line side of pad holder) than pair of right and left anterior superior iliac spine 8,8 position separately when pad holder 1 is worn.
The width of the 1st elongation suppressing portion 21,22 of front portion is not particularly limited, and for example the width of the structure of illustrative example is about 0.5～5cm.
About pad holder 1 of the present invention vertically, in the front portion, the part that approaches the waist peristome most (being the part that has arrived folding line 1a, 1a in the present embodiment) of the 1st elongation suppressing portion 21,22 of front portion sets with waist opening elastic 51 devices spaced apart.In other words, in the front portion, vertical at pad holder, between the 1st elongation suppressing portion 21,22 of waist opening elastic 51 and front portion, on the part suitable, there is the high zone of the 1st elongation suppressing portion 21,22 extensibilities than the front portion with wearer's abdominal part.By this structure, pad holder follows especially when posture change skin flexible of (anteflexion, stand sit down etc.), can suppress the landing of pad holder in wearing, even thereby and can guarantee also when motion or under the expansible significantly situation of abdominal part in when deep breathing etc. that the degree of freedom of abdominal part keeps comfort level.In addition, the landing of being undertaken by the 1st elongation suppressing portion 21,22 of front portion suppresses, even weaken tying tight of waist that waist opening elastic 51 brings, also can suppress the landing of pad holder, so can when preventing the crispaturaing of waist peristome peripheral part, alleviate the sense of discomfort in the dress and the vestige of tying tight.
Preferably, the 1st elongation suppressing portion 21,22 of front portion as shown in Figure 1, when the skin opposed faces that makes front portion 2 and back portion 3 each other face contact and when making pad holder 1 become plane naturalness, end 21a, the 22a of front portion first half 2U side reaches folding line 1a, the 1a that the sidepiece at keeper produces.Above-mentioned end 21a, 22a can not reach folding line 1a, 1a respectively yet, but in the case, to the distance of folding line 1a, 1a preferably below the 30mm, particularly preferably be below the 10mm.In addition, the 1st elongation suppressing portion 21,22 of front portion preferably, as shown in Figure 1, end 21b, the 22b of front portion Lower Half 2D side enters into the zone 41 of 6,6 of pair of leg peristomes, more preferably, reach when the skin opposed faces that makes front portion 2 and back portion 3 each other face contact and the folding line 1b that produces at lower crotch 4 when becoming plane naturalness.
From improving pad holder 1 and absorbent pad 7 viewpoint to the connecting airtight property of wearer's crotch part, the distance L 4 (with reference to Fig. 1) that pair of leg peristome on the width of pad holder is 6,6 is 3～15cm, more preferably 6～12cm preferably.In addition, the 1st of the front portion the elongation suppressing portion 21,22 is not preferably intersected mutually at front portion Lower Half 2D.The lower end of front portion Lower Half 2D and back portion Lower Half 3D be positioned at when the skin opposed faces that makes front portion 2 and back portion 3 each other face contact and the position of the folding line 1b that produces at lower crotch 4 when making pad holder 1 become plane naturalness.
The elongation suppressing portion of the 1st elongation suppressing portion and back portion described later of front portion be pad holder vertically on maximum percentage elongation than the little part of the part except the elongation suppressing portion of front portion or back portion of trunk peripheral part of front portion or back portion (particularly being positioned at the part of at least one side of the both sides of the elongation suppressing portion that clips front portion or back portion), or on pad holder vertical applied specific load the time percentage elongation than the little part of other parts of trunk peripheral part of front portion or back portion (particularly being positioned at the part of at least one side of the both sides of the elongation suppressing portion that clips front portion or back portion). From the viewpoint of wearing off property and wearing feeling, preferably the former.The maximum elongation rate is meant the percentage elongation when being elongated to the length (length before the material damage) that can not continue to extend, and the maximum elongation rate is obtained with following formula (1).
Maximum elongation rate (%)={ length before (length before the length-elongation after the elongation)/elongation } * 100% ... (1)
The maximum elongation rate of the 1st elongation suppressing portion 21 (22) of front portion is preferably less than 180%, and more preferably 20～150%, more preferably 40～120%.
On the other hand, the 1st elongation suppressing portion 21 (22) the high extensibility in addition of front portion partly is the part that extensibility is relatively higher than the 1st elongation suppressing portion of front portion, for example be arranged in the high extensibility part of at least one side that the 1st elongation suppressing portion 21 (22) that clips the front portion is positioned at the part of its both sides, the maximum elongation rate is seen preferably more than 120% from this point that wears off easiness and wearing feeling of pad holder, particularly preferably be more than 125%, more preferably more than 150%, more preferably more than 180%, and, particularly preferably be 50～150% with the difference of the maximum elongation rate of the 1st elongation suppressing portion 21 (22) of front portion preferably more than 30%.In the present embodiment, preferably, high extensibility part 2a, 2b (2a, 2c) maximum elongation rate separately are above-mentioned scope.
In addition, more than 35% of the gross area of the pad holder 1 under the naturalness of pad holder 1 (gross area of outer surface or inner surface), more preferably more than 50%, more preferably more than 65% for the part higher than the 1st elongation suppressing portion 21 (22) extensibilities of front portion, be the bigger part of maximum elongation rate, this from pad holder wear off easiness and the wearing feeling this point is preferred.The total area of the 1st elongation suppressing portion 21,22 of front portion be the pad holder 1 under the naturalness the gross area more than 5% less than 30%, particularly preferably be more than 3% less than 20%, more preferably more than 5% less than 15%, it is preferred that this viewpoint from the stable retentivity of absorbent pad waits.In addition, the 1st elongation suppressing portion 31,32 about back portion described later also is same.
The maximum elongation rate of the 1st elongation suppressing portion 21 (22) of front portion is measured along vertical (Y direction) elongation of pad holder with sample by the measurement that makes the 1st elongation suppressing portion 21 (22) that comprises the front portion.
On the other hand, the maximum elongation rate of the 1st of the front portion the elongation suppressing portion 21 (22) high extensibility part is in addition measured along vertical (Y direction) elongation of pad holder with sample by the measurement that makes the 1st elongation suppressing portion 21 (22) that comprises this extensibility part and do not comprise the front portion.
Particularly, pad holder from measuring object, according to size under naturalness is that direction longitudinally (Y direction) along pad holder is for 100mm, be the rectangular shape of 50mm along the direction (directions X) of width, and to spread all at least that the scope of 60mm includes the mode that suppressing portion 21 (22) is extended in the 1st of front portion measuring length direction central authorities with sample, downcut, with the part of the rectangular shape of this cutting-out as the measurement sample.In addition, in the making of said sample, the scope total length that spreads all over 60mm with the 1st elongation suppressing portion 21 (22) of front portion is configured to prerequisite continuously, and the situation that high extensibility partly is included in the part but the 1st elongation suppressing portion 21 (22) of front portion is disconnected on a part is also contained in this category.
Sample will be measured so that its length direction (Y direction) becomes the mode of draw direction is installed on the chuck of cupping machine.At this moment, the situation that all clips the 1st elongation suppressing portion 21 (22) of front portion on which of up and down chuck is confirmed.If distance is 50mm (clamping part is for measuring the part with the front and back 25mm of sample) between chuck.To measure sample and stretch, measure distance between the chuck when measuring at least a portion generating material destruction of using sample with 300mm/min.
But, do not have under the situation of material damage distance between the chuck when measuring 100N load with sample in measurement after the 100N load yet.
Can not extract as described above under the situation of sample from the pad holder of measuring object, suitably change distance, clamping width between specimen length, specimen width, chuck, the elongation suppressing portion is clipped in two chucks.
The measuring method of the maximum elongation rate of the 1st elongation suppressing portion 21 (22) the high extensibility part in addition of front portion is according to the above.But, when sample is used in the cutting-out measurement, make that not including the 1st of front portion in measuring with sample extends suppressing portion 21 (22).In having to measuring, comprise under the situation of the 1st elongation suppressing portion 21 (22) of front portion, do not regulate so that in which of upper and lower scroll chuck, all be clamped to the 1st of front portion and extend suppressing portion 21 (22) with sample.
In addition, the elongation suppressing portion of front portion or back portion " pad holder vertically on applied specific load the time percentage elongation littler than other parts of trunk peripheral part of front portion or back portion " be meant, suppose that under the common state of wearing Excreta is maintained at state on the liner, percentage elongation was less when the percentage elongation during with 3N load compared.Measure with preparation method and measuring method measuring method according to above-mentioned maximum elongation rate except load value of sample and carry out.
The pad holder 1 of present embodiment is because the 1st elongation suppressing portion 21 of front portion, 22 with above-mentioned form formation, even so because of the power that pad holder 1 is left behind being arranged downwards based on effect when the wearing of pad holder 1 such as the weight increase of the absorbent pad 7 of imbibition, also because the 1st elongation suppressing portion 21 of front portion, 22 are stuck in anterior superior iliac spine 8, on 8, and the 1st elongation suppressing portion 21 of front portion, the elongation of the high extensibility part that 22 opposings are made of Stretchable sheet and suppress lower crotch 4 moving downwards is so can prevent the landing downwards of absorbent pad 7 and pad holder 1 effectively.Under the bigger situation of the absorptive capacity of absorbent pad 7, for example absorptive capacity (measuring with normal saline) are situation more than the 250mL or more than the 300mL, it is big that the power of leaving behind that absorbent pad 7 is brought becomes, even but under these circumstances, the effect of the 1st elongation suppressing portion 21,22 by the front portion also can keep (hold) hip crotch the wearer with fit state with absorbent pad 7.In the mode that does not have such elongation suppressing portion, generally need realize that landing prevent by the waist elastomeric element, need work hard improving on its power of tying tight etc., but relaxed, eliminated the undesirable condition that is accompanied by this mode in the present invention effectively.
In addition, extend to the sidepiece of the front portion first half from the width central part side of front portion Lower Half by the 1st elongation suppressing portion of front portion always, the 1st elongation suppressing portion of front portion presents the effect of slinging, the undesirable condition that can not be lifted fully just need not be readjusted and can easily product integral body be lifted the appropriate location although can prevent to be stuck near the product crotch portion when having used flexible material but lifting for whole on the huckle.When leaving behind, the 1st elongation suppressing portion that will be positioned at the front portion on the anterior superior iliac spine by wearer or care-giver unloads from anterior superior iliac spine, and the landing of the 1st of front portion being extended suppressing portion suppresses the effect releasing, can easily leave behind.
In order to prevent that effectively absorbent pad 7 or pad holder 1 landing and pad holder 1 downwards from tackling neatly because of breathe waiting abdominal circumference that causes to change, preferably the 1st of the front portion the extends suppressing portion 21,22 and does not intersect mutually on the first half 2U of front portion at least.
Particularly, the pad holder 1 of present embodiment as shown in Figure 2, the part of the covering anterior superior iliac spine 8,8 of front portion 2 is to extend part 2b, the 2c of the high extensibility of suppressing portion 21,22 extensibilities than the 1st of front portion, is stuck in easily on the anterior superior iliac spine 8,8 near the 1st elongation suppressing portion 21,22 of front portion and the part 2b of high extensibility, the boundary portion between the 2c.Therefore, can more effectively prevent absorbent pad 7 or pad holder 1 landing downwards.Particularly, are retractilities if cover the part of anterior superior iliac spine 8,8, then in wearing, follow wearer's motion easily, and when the 1st elongation suppressing portion 21,22 of front portion is blocked, contact the soft-touch on anterior superior iliac spine, so be preferred.
