Absorber 4 is by top flat 2 and egative film 3 clampings and fixing.The extended waist 5 of direction forwards, backwards at the edge, front and back end of absorber 4,5 and be respectively arranged with to the extended shank 6,6 of transverse direction from the left and right sides edge and be used to make the each several part of diaper to paste suitable waist elastic members 51 and leg elastic members 61 mutually with the wearer.In addition, be formed with three-dimensional guard shield 11 respectively in vertical left and right sides of the top flat side of diaper 1.Free end at three-dimensional guard shield 11 disposes three-dimensional guard shield elastomeric element 111, forms fold.
There is no particular restriction as above each parts that constitute diaper 1, can use in this technical field at present known those.For example, as top flat 2, can use hydrophilic non-woven fabrics or perforated film etc.As egative film 3, can use the thin film of liquid impermeability etc.As absorbability core 41, can use particle long-pending slim of fluff pulp and high water absorbency polymer.As elastic telescopic parts 61,71, can use various elastomeric materials.
As depicted in figs. 1 and 2, the disposable diaper 1 of the present embodiment contains between egative film 3 and the 2nd mount paper 42b and contacts the hydrophilizing agent (hereinafter referred to as changing agent) 10 that then visually changes with moisture.In the present embodiment, variation agent 10 is set its surface with the 2nd mount paper 42b that is disposed at egative film 3 sides is contacted, this variation agent 10 is on the verge of egative film 3.More particularly, to mix the variation agent 10 that hot-melt adhesive composition that pH indicator (for example bromophenol blue) wait constitutes in the component in adhesion with method described later and be applied on the face relative of egative film 3, the absorber 4 that is formed by mount paper 42a, 42b coating absorbability core 41 be set on this absorber opposite face with absorber.In this utility model, so-called " visually changing " is the notion that comprises following situation: the situation of the front and back change color that contact with moisture, contact the situation of color disappearance with moisture and contact the situation that color manifests with moisture.The situation of change color adapted before and after the variation agent 10 of the present embodiment contacted with moisture.
In the present embodiment, change the middle body of agent 10 at the diaper width, run through posterior components A, gang lower part B of diaper and veutro portion C and be set to linearity.More particularly, on the width of diaper, be set to 3 elongated lines arranged side by side.Because this structure compares by posterior components A or veutro portion C with the living visual variation of difficult labour, can distinguish the visual variation in the variation agent 10 of thigh lower part B clearly.And, make variation agent 10 be thin width belt shape, on the width of diaper many (being 3 in the present embodiment) arranged side by side, therefore visual variation is easier distinguishes.
In disposable diaper of the present utility model, has obvious characteristics in the following areas: even (i) on egative film 3, impose to contact and also do not produce the pattern 12 that visually changes with moisture, (ii) diaper 1 the thigh lower part B, egative film 3 is at the thickness direction of diaper 1, only have pattern 12 with the position non-overlapping portions that contains the agent 10 that changes, (iii) changing the color of agent 10 generation visible change front and back and the color of pattern 12 is Adjacent color.In the disposable diaper 1 of the present embodiment, the pattern row of 2 row along the pattern 12 of the rabbit of diaper longitudinal extension are arranged 3 diaper width arranged outside that change the line of agent 10.Pattern 12 is arranged on egative film 3 China and foreign countries and adorns on the opposite face of screening glass 7.In each pattern row, the rabbit of aeruginous pattern and pinkish rabbit are disposed alternately.On the other hand, each line that changes agent 10 is yellow before variation, becomes aeruginous after variation.Specifically, use contains the variation agent of bromophenol blue as changing agent 10.
Diaper 1 with the present embodiment is an example, and the mechanism of the property the distinguished raising that visually changes is described.Before urinating, pattern 12 is an aeruginous, and the line that changes agent 10 is yellow.Therefore, both can observed person's (when diaper wearer is the baby, being mother etc.) be distinguished as different colors.But, if arriving, the back urine of urinating changes agent 10, then change agent 10 and become aeruginous.Therefore, owing to being similar in color of pattern 12 and the line that changes agent 10, so the observer has at first felt inharmonious.Subsequently, it is identical to impel the color of noticing the color of finding pattern 12 and the line that changes agent 10 to become further, has then known the replacing period of diaper 1.This moment, importantly in the B of thigh lower part, the line and the pattern 12 that change agent 10 were separated by a distance at the diaper width.That is, in the thigh lower part B of diaper 1, egative film 3 only has pattern 12 with the position non-overlapping portions that contains the agent 10 that changes at the thickness direction of diaper 1.Both are overlapping if change the line of agent 10 and pattern 12, then can not find to change the change color of the line of agent 10, and the observer does not recognize that the probability in replacing period of diaper 1 increases.
Change the line and the spacing distance of pattern 12 of agent 10, can't find, if cross far away then be difficult for feeling inharmonious sense with respect to the change color of variation agent 10 if cross change color near then that change agent 10.Be familiar with from these, both spacing distances are 5～30mm, preferred especially 7～25mm.
In the diaper 1 of the present embodiment, in the vertical whole zone of diaper 1, the line and the pattern 12 that change agent 10 are separated by a distance at the width of diaper, even but the part beyond the B of thigh lower part both overlapping also it doesn't matter.Its reason is: have the urinate part of probability of maximum acceptance and be a gang lower part B, if it is separated by a distance therefore only to change the line and the pattern 12 of agent 10 in the B of thigh lower part, just the variation that the observer can distinguish between colors fully.Though say so, because the wearer waiting in bed, urine flows out from unexpected direction sometimes, even therefore on posterior components A and veutro portion C, also the line of advantageous variant agent 10 and pattern 12 are separated by a distance at the width of diaper.
For the similarity of the color of the design and color 12 of the line that changes agent 10, be that the observer with common attention observes, think that can distinguish into similar degree gets final product.In order to improve the property distinguished, preferably in according to the colorimetric scale of 24 colors of Ostwald (Ostwald) hue circle classification for identical form and aspect (the Japanese original text is the color ticket) or in the form and aspect sequence number only differs 1 scope.
Below, employed variation agent 10 in this utility model is described.Change agent and be the hydrophilic compositions that contains the material that contacts with moisture and visually change (below, be called electrochromic substance).As electrochromic substance, can enumerate pH indicator etc.For example, can use known printing ink or indicator.As the pH indicator, when absorbent commodity is disposable diaper as the present embodiment, the preferred use in the pH indicator that contacts the front and back change color with urine.PH such as for example preferred bromophenol blue, methyl orange, alizarin S, bromocresol green, C.I. 13020., bromocresol purple, "diazoresorcinol" are the pH indicator of variable color in 3～7 o'clock.
Change agent 10 with before moisture contacts, must stably be fixed on the surface of egative film 3 and/or the 2nd mount paper 42b.As this fixed method of realization, easy and feasible method is that variation agent 10 is become electrochromic substance and the blended hydrophilic compositions of adhesive, is applied to the surface of egative film 3 or the 2nd mount paper 42b.As adhesive, from the compatibility aspect of electrochromic substance, the adhesive of preferred possess hydrophilic property.As such material, for example can enumerate and the hydrophilic polymers that plays the bonding agent effect of the 2nd mount paper 42b and egative film 3 before moisture contacts.As hydrophilic polymer, preferably use any among Polyethylene Glycol (PEG), polypropylene glycol (PPG), polyvinyl alcohol (PVA), polyamide, the vinyl pyrrolidone homopolymer etc.From giving certain fixedly aspect, the number-average molecular weight of these hydrophilic polymeies is preferably 1000～50000, is preferably 2000～20000 especially.
Even contacting also with moisture, pattern 12 visually do not change.Specifically, do not change even contact color, or color does not disappear yet with moisture yet.Such pattern is preferably implemented with water-insoluble printing ink.As such printing ink, can enumerate for example cellulose nitrate prime system printing ink, polyamide-based printing ink, acrylic acid series printing ink, dye type printing ink etc.
As the present embodiment, when the visual variation that changes agent 10 is because variable color when producing, lightness (or being called brightness) L* that measures from the diaper exterior side of egative film 3 before variation agent 10 visually changes is preferably 15～80, be preferably 20～70 especially, lightness L* after visually changing is preferably 20～80, is preferably 30～80 especially.In addition, from see through egative film 3 or outside adorn screening glass 7 and can distinct see pattern 12 (clear), the lightness L* of the pattern of measuring from the diaper exterior side of egative film 3 12 is preferably 30～90, is preferably 35～90 especially, most preferably is 40～90.
When the color before variation agent 10 visually changes and the color of pattern 12 were Adjacent color, the lightness L* that changes before agent 10 visually changes was preferably little by 1～15 than the lightness L* of pattern 12.On the contrary, when the color after variation agent 10 visually changes and the color of pattern 12 were not Adjacent color, the lightness L* that changes after agent 10 visually changes was preferably little by 1～15 than the lightness L* of pattern 12.Therefore, under any circumstance, the lightness L* that changes after agent 10 visually changes is preferably about-10～5 with the difference that changes preceding lightness L*.Like this, distinguished by the observer though before urinating, change the line of agent 10, unshowy comparatively speaking when with respect to pattern 12, so be favourable for the raising of the design of diaper 1.On the other hand, the line that changes agent 10 when the back of urinating is for the similar color of pattern 12 time, owing at first sight making the observer feel the enlarged areas of pattern 12, produced inharmonious sense, on the contrary, when being the color different, make the observer produce the impression that line emersion seemingly comes with pattern 12.Therefore, can learn aspect diaper change period it is favourable really the observer.
