Description

經濟部中央標準局員工消費合作社印製 S08540 A7 B7 五、發明説明(1 ) <產業上之利用領域> 本發明乃與生理用衛生棉相關,進而詳言之,乃有關 於吸收保持經血之生理用衛生棉或墊。 <習知技術> 曰本專利實公平5 _ 3 9 6 9 1號公報中揭露了有在 衛生棉上面之兩側沿其長方向延伸之同時,在其約中央部 間隔狹窄之一對壓條溝之生理用衛生棉。依相關條溝,可 提高衛生棉對女性局部之適合密著性。又,著用衛生棉之 中央部產生扭曲時,可藉此條溝阻止此扭曲延伸至衛生棉 側緣爲止。藉此,經血沿扭曲添至側緣爲止,便可避免側 漏之問題產生。 <發明所欲解決之課題> 前記習知之衛生棉之吸液性芯材之壓條溝之密度比芯 材中央部之密度高極多,流入條溝之經血有向長方向過快 擴散之虞。條溝乃形成於衛生棉之吸液性芯材之側緣附近 之故。因此擴散使衛生棉比沒有條溝之情況更促使側緣部 弄髒,與此側緣部相接之內褲弄髒之頻率便變高。 本發明便以維持形成有條溝之情況之效果,抑制該條 溝中之經血之擴散爲主要課題。 <解決課題之手段> 爲解決前記課題,本發明中以由透液性表面薄片,不 本紙張尺度適用中國國家標準(CNS ) Λ4現格(210X 297公釐) (請先閱讀背面之注意事項再填寫本頁) 訂 經濟部中央樣準局員工消费合作社印製 A7 B7 五、發明説明(2 ) 透液性裏面薄片及介於此兩薄片間之吸液性芯材所成,於 該芯材所在位e之區域上面兩側上有向其長方向延伸之同 時,其中央部中有問隔狹窄之一對壓條溝之生理用衛生棉 爲前提。 相關前提中,前記條溝具有於其底面之長方向交互並 列之高壓擠部及低壓擠部者爲本發明之特徵。 <實施例> 參照附圖對本發明詳明如下: 圖1中部分剖開立體圖所示之生理用衛生棉1乃由透 液性表面薄片2 ,不透液性裏面薄片3及吸液性芯材所構 成,表裏面薄片2 ,3 ,在芯材4四周延伸部分重合,內 面彼此水密地相接合。衛生棉1之上面兩側部上形成向長 方向延伸之一對壓條溝5 ,此條溝5之中央部間隔最窄, 其向長方向兩端間隔漸漸變寬。藉條溝5 ,衛生棉1可大 大地改善其對女性局部之適合密著性。 圖2 ,3爲圖1之部分放大平面圖及圖1之III — m線 斷面圖。於這些圖中,條溝5之底面5A上有厚度(高度 )B之低壓擠部8及厚度C之高壓擠部9 ,兩部8 , 9向 條溝5之長方向交互並列。條溝5之上面開口 5 B之寬度 比其底面5 A之寬度大,且開口上緣部5 C形成爲圓弧。 低壓擠部8及高壓擠部9乃將底面5 A向寬度方向橫切。 更具體言之,位於衛生棉1之對縱軸X歪斜之位置之同時 (參照圖1 , 2),比底面5A之寬度更窄地向其寬度方 本紙張又度適用中國國家標隼(CNS ) Λ4規格(210X 297公聲) (請先閱讀背面之注意事項再填寫本頁) 、-° S08540 A7 B7 五、發明説明(3 ) 向延伸。條溝5爲,相對於其附近之厚度A,B二0. 7 〜0· 2XA,C=0. 5〜0· 05XA,B>C所成 ,而理想爲高壓擠部9之密度0. lg/cm3以上,而 低壓擠部8之密度比高壓擠部9之密度低地壓擠成。條溝 5則以芯材4之全長之1/2〜4/5之長度,及1〜 5 mm之宽度爲理想。低壓擠部8及高壓擠部9爲於條溝 5之長方向上有〇· 8〜4mm爲理想。 沿條溝5之內外側壁5D1 ,5D2附近之芯材4部 分亦因有條溝5被壓擠形成之故,即使不做成前記壓擠部 8 ,9般,亦比在壓擠時未受到壓擠作用之其他面域之密 度高一節應能理解。圖3中,內側壁5D 1之開口上緣 5 C比外側壁5 D 2之開口上綠5 C圓弧之長度尺寸較大 ,因此,位於者之芯材4部分比位於後者之芯材4部分被 以更廣範圍且更高密度地壓擠。故,流入條溝5之經血被 內側壁5 D 1側在條溝內吸收擴散,而自外側壁5 D 2向 衛生棉之外側緣擴散側漏則很少發生。理解上節,則內側 壁5 D 1側之芯材4部分做成比外側壁5 D 2側之芯材部 分高度度地壓擠形成條溝5乃爲理想。 相關條溝5之形狀可將衛生棉1以成型模高壓壓擠而 得,在壓擠部位上,如使其含微量之水或在表面薄片2及 芯材4之間介有熱熔型接著劑而在加熱下壓擠可使此壓擠 形狀安定。 如此構成之衛生棉1 ,如圖1之箭號P,Q所示,經 向被排泄流入條溝5後,低壓擠部8之經血向密度高之高 本紙張尺度適用中國國家標準(CNS ) A4規格(2IOX 297公麾) (請先閲讀背面之注意事項再填寫本頁) 訂 經濟部中央棣準局員工消費合作社印製 經濟部中央標隼局貝工消f合作社印製 A7 _____B7 五、發明説明(4) 壓擠部9快速擴散。一方面,因該部9之周圍爲相對之低 密度之故,該部9之經血不會輕易地擴散至這樣之周園。 故,此衛生棉1爲經血在條溝5中時,阻止其向長方向迅 速擴散,可抑制經血自條溝5至衛生棉1之側緣向外部蔓 延0 於本發明中,芯材4可爲於粉碎之紙漿中混合高吸水 性聚合物粉末或熱可塑性合成纖維。將條溝5在加熱下壓 擠形成之情況中,相關之纖維乃因此加熱而被塑型,對防 止壓擠形狀之崩潰能發揮作用。又,纖維若爲疏水性者, 則於由粉碎之紙漿所成之芯材4,能對經血賦予擴散性。 表面薄片2乃使用不織布或開孔之塑膠膜,裹面薄片3則 以使用塑膠膜爲理想。衛生棉1之各構件之接合可使用熱 熔型接著劑等之接著劑之外,亦可利用對熱熔融性素材之 熔著技術。附圖中省略這些接合手段之圖示。 <發明之效果> 於本發明相關之生理用衛生棉中,其上面兩側上形成 有條溝,可藉而提高對女性局部之密著性,又,衛生棉中 央部所產生之扭曲難以向周緣部延伸。相關條溝則因向其 底面之長方向,相對之高密度之壓擠部與低密度之壓擠部 交互並列之故,抑制流入條溝之經血向其長方向過度地擴 散,藉此,與衛生棉側緣部或底部相接之內褲亦不會弄髒 。(請求項1 ,4 ) 即使條溝係由壓擠而形成,因其開口上緣乃爲園弧, 本紙張尺度適用中國國家標準(CNS ) A4况格(210X 297公釐)~~7~ m 1^1^1 Mu n^l· enn —B^i— f 1 才 .νβ (請先閲讀背面之注意事項再填寫本頁) 經濟部中央標準局員工消費合作杜印裝 ^08540 a? B7 五、發明説明(5 ) 不會對女性局部造成刺激,經血乃園滑地流入條溝中。( 請求項1 ,2〉 此種衛生棉,一般乃係對其長方向直角地彎折重曼單 片包裝之故,同直角方向上許多細小橫向皺摺會在折叠處 產生。此橫向鮍摺雖亦爲經血側漏之成因,且亦與表面薄 片之材質有關,但本發明因.條溝及其底面之高低壓擠部, 比起沒有這些設計之情況,可降低前記橫向小皴摺之產生 。(請求項1 ,2 ) 形成條溝之內外側壁中,沿該內側壁之芯材部分比沿 該外側壁之芯材部分密度高之故,前者之芯材部分比後者 之芯材部分更能吸收擴散經血,而能有效地防止經血側漏 (請求項5 ) <圖面之簡單說明> 圖1:生理用衛生棉之部分剖開立體圖。 圖2 :生理用衛生棉之部分放大平面圖。 圖3 :圖1之ΠΙ — III線斷面圖。 <符號之說明> 1.生理用衛生棉 2.表面薄片 3.裹面薄片 4.芯材 5.條溝 8.低壓擠部 9 .高壓擠部 本紙張尺度通用中國國家標隼(CNS ) Λ4規格(210X297公t ) (請先閱讀背面之注意事項再填寫本頁) 訂
