1232096 (1) 玖、發明說明 【發明所屬之技術領域】 本發明’係關於很適合作爲用後即棄型紙尿褲或訓練 尿褲、失禁者用尿褲等之使用之用後即棄式短褲型穿用物 品0 【先前技術】 於用後即棄型紙尿褲等之用後即棄型穿用物品,習知 有使用矩形之體液吸收性積層片,於該積層片之臀下域兩 側部分別形成有朝向積層片內側折入之折入部者。 例如,日本實開昭4 7 — 3 6 7 3 4號公報(日本專利文獻 1 )所記載之紙尿褲,呈矩形之片狀之紙尿褲本體片,於 臀下域具備有折入部,該折入部對於將本體片之長度方向 二等分之中心線,是以成爲對稱之方式形成,換言之,以 在紙尿褲之前後方向成爲對稱之方式而形成。 於日本特開昭50 - 33〇44號公報(日本專利文獻2) 所記載之紙尿褲也具備有折入部,該折入部是藉由將呈矩 形之體液吸收性之片狀材料,沿著中央橫斷線以及從中央 橫斷線之中點呈放射狀延伸之線,予以折彎而形成,於折 入部,相互對向之紙尿褲之內面彼此間爲部分被固定。該 紙尿褲之折入部,也對稱於中央橫斷線,亦即在紙尿褲之 前後方向以成爲對稱之方式而形成。 曰本特開2003 - 1 0244號公報(日本專利文獻3 )所 記載之短褲型之穿用物品,是被作爲用後即棄式短褲型紙 -5- (2) 1232096 尿褲等而使用者,呈矩形之體液吸收性積層片被折彎成U 字狀,並以臀下域爲中心延伸至前後腰圍域。該積層片於 臀下域具備有折入部,該折入部,於短褲型之穿用物品之 最下端部之積層片橫斷線,以及從該橫斷線之中點延伸至 積層片之兩側緣部之放射狀線之處,藉由將積層片折彎而 形成。該穿用物品之折入部也對稱於上述橫斷線,亦即以 在穿用物品之前後方向成爲對稱之方式而形成。 於曰本專利文獻1、2、3之任一穿用物品,其形成於 積層片臀下域之折入部都有使積層片之寬幅部分變窄之作 用,同時發揮作爲保持排泄物之口袋之功能。 [曰本專利文獻1 ]日本實開昭4 7 — 3 6 7 3 4號公報 [曰本專利文獻2]日本特開昭5 0 — 3 3 044號公報 [日本專利文獻3]日本特開2003 - 10244號公報 【發明內容】 [發明所欲解決之技術問題] 於日本專利文獻1、2、3,其形成於體液吸收性積層 片之折入部全都在紙尿褲之前後方向形成對稱,形成有該 折入部後之體液吸收性積層片,實質上也於前後方向形成 對稱。此等積層片,爲在比折入部後方之部分處,覆蓋紙 尿褲穿著者之背側,在比折入部前方之部分處,覆蓋穿著 者之腹側者,不過若於背側以可較寬廣覆蓋臀部之方式將 積層片之寬度製作得較寬的話,則於腹側會因該寬幅寬廣 之積層片而妨礙穿著者之腳之自由動作。另一方面,若以 -6 - (3) 1232096 不妨礙腳之動作之方式將積層片之寬度製作得較窄的話, 則臀部附近之積層片之體液吸收能力不足,會有產生體液 易於漏出之情形。 本發明’其課題爲以其體液吸收部在臀下域具備有折 入部之用後即棄式短褲型穿用物品作爲對象,以不會妨礙 該物品穿著者之腳之動作,而且不會產生體液漏出之方 式,改良上述折入部。 [解決問題之技術手段] 爲了解決上述課題,本發明之對象爲,以下之用後即 棄式短褲型穿用物品。亦即,具備有前腰圍域及後腰圍域 以及臀下域,而於上述臀下域形成有朝向上述前後腰圍域 方向縱長延伸之體液吸收部,上述體液吸收部具備有朝向 上述前後腰圍域方向大致平行延伸之兩側緣部,其位於上 述前腰圍域及後腰圍域之部分之內面彼此間爲相互對向, 以大致呈U字狀之方式朝向縱長延伸之方向折彎,·上述臀 下域之上述體液吸收部,具備有從延伸於上述臀下域之寬 幅方向之橫斷線之中點以及位於從上述中點朝向兩側等距 之處之上述橫斷線上之二點之任一點,對上述橫斷線形成 夾角α ,並分別朝向靠近上述前腰圍域之上述體液吸收部 之上述兩側緣部延伸之一對第1折曲線,以及對上述橫斷 線形成夾角Θ並分別朝向靠近上述後腰圍域之上述體液吸 收部之上述兩側緣部延伸之一對第2折曲線;於上述臀下 域之上述體液吸收部,其位於各上述兩側緣部之上述第1 (4) 1232096 折曲線與上述第2折曲線間之部位,又具備有以朝向上述 體液吸收部內側之方式被折彎形成之折入部、及一對位於 比上述第1折曲線更靠近上述前腰圍域之第1非折入部, 以及一對位於比上述第2折曲線更靠近上述後腰圍域之第 2非折入部之用後即棄式短褲型穿用物品。 於有關此短褲型穿用物品,本發明之特徵,爲上述體 液吸收部之上述第1非折入部之擴開之程度形成得較小, 上述第2非折入部之擴開之程度形成得較大。 於本發明,具有如以下般之實施形態。 (1 )上述橫斷線位於上述穿用物品之上下方向之上 述臀下域之最下端部,上述夾角α比上述夾角々大。 (2 )上述橫斷線從上述穿用物品之上下方向之上述 臀下域之最下端部朝向靠近上述前腰圍域處偏倚,上述夾 角α爲與上述夾角点相等或比上述夾角卢大。 (3)上述夾角α在35〜60度之範圍內,上述夾角点 在10〜30度之範圍內。 (4 )上述橫斷線從上述臀下域之最下端部朝向靠近 上述前腰圍域處偏倚1 0〜5 0 m m。 【實施方式】 作爲有關本發明之用後即棄式短褲型穿用物品,以短 褲型紙尿褲爲例,並參照附圖詳細說明本發明如下。 第1、2、3圖,爲用後即棄式短褲型紙尿褲1之立體 圖' 及將第1圖之紙尿褲部分剖開顯示之剖視圖,以及顯 -8- (5) 1232096 不第1圖之111 一 ΠI線斷面之圖。π I — 111線斷面,爲將 第1圖之紙尿褲1二分爲前腰圍域6及後腰圍域7之面, 於該面會顯露紙尿褲1之最下端部5 1之內部構造。紙尿 褲1,爲具備有相互垂直相交之高度方向與寬幅方向,以 及前後方向者,高度方向爲第1圖之上下方向,前後方向 爲第1圖之以箭頭P、Q顯示之方向,寬幅方向爲第1圖 之沿著III 一 III線之方向,亦即爲第3圖之左右方向。有 關此紙尿褲1,爲由呈短褲型之覆蓋部2,以及用以吸收 保持體液之體液吸收部3所構成。覆蓋部2,具備有與紙 尿褲穿著者之肌膚相互對向之內面2a,以及與著衣相互 對向之外面2b,由覆蓋該穿著者之前後腰圍部與腿根部 之前腰圍域6及後腰圍域7以及臀下域8所構成。前後腰 圍域6、7,在紙尿褲1之兩側部以合掌狀相互重疊,並 朝向上下方向在斷續排列之部位4處相互接合,藉由此等 兩域6、7區劃成腰圍開口 9,藉由此等兩域6、7及臀下 域8區劃成一對腿圍開口 1 1。於各腰圍開口 9及腿圍開 口 1 1之緣部’設置有於拉長狀態下之複數條彈性構件 1 2、1 3。體液吸收部3,位於覆蓋部2之內面2 a之側, 內面彼此對向,以大致呈U字狀之方式,以臀下域8爲中 心朝向前腰圍域6及後腰圍域7縱長延伸。吸收部3,又 於紙尿褲1之最下端部5 1之附近具備有折入部5 0,於該 折入部50,朝向將紙尿褲1之寬度二等分並朝高度方向 延伸之縱中心線A -

C2間之部分3d,以可寬廣包覆紙 尿褲穿著者臀部之方式,將夾角^ ,作得較小而將虛線丁 -14 - (11) 1232096 與虛線T間之夾角ό作得較大,較佳爲將夾角6作在1 2 ο 〜1 6 0度之範圍內。如此,於紙尿褲1,即使吸收部3爲 如第4圖所示被作成矩形,以臀下域8爲中心朝向前後腰 圍域6、7縱長延伸者,於腹側不會有妨礙穿著者之腳之 動作之情形,於背側可防止體液從臀部附近漏出。 根據第2、3圖可明顯得知,於紙尿褲1之吸收部 3,在折入部5 0之內側形成有內側口袋3 Oa,於覆蓋部2 之側緣部分8 a與吸收部3之間形成有外側口袋3 Ob。 將本發明之紙尿褲1穿著於乳幼兒身上時,在母親將 手伸入於腰圍開口 9之緣部內側,將該開口 9大大撐開 時,要使乳幼兒之腳穿過腿圍開口 1 1。於該紙尿褲1,將 開口 9如此撐開之紙尿褲1之變形,不會影響遠離開口 9 之臀下域8之與覆蓋部2爲不同個體之吸收部3,而且即 使撐開腿圍開口 1 1而動到臀下域8之側緣部分8a,由於 吸收部3之側緣部分2 6沒有接合於側緣部分8 a,故吸收 部3幾乎不會移動。因此,吸收部3之折入部5 0,其形 狀不會變形。吸收部3,亦可把沿著含於其中之芯材2 1 之虛線S、T、U之部位,以吸水性材料塡滿’將該材料 藉由壓花加工用輥筒等予以局部加壓或是加熱加壓’將該 等部位作成剛性比其周邊域高’且並行於該等之部位而折 彎。又,吸收部3,亦可將沿著虛線U之部位塡滿吸收性 材料,另一方面,於沿著虛線S、T之部位形成除了吸收 性材料外之凹溝2 0 s,2 01,其後形成折入部5 0 °吸收部 3,以把其綾線較尖之折曲線沿著虛線s、τ而形成者爲理 -15- (12) 1232096 想,不過沿著虛線U之折曲線,其稜線未必爲尖銳。 第6圖’爲與顯示本發明之實施形態之一例之第4圖 相同之圖。於該紙尿褲丨,以比在第4圖將紙尿褲1之長 度二等分之橫斷線B -

D及虛線T之夾角 相同,或是作得比夾角点^大。即使夾角α與夾角冷! 相同,但因吸收部3在比將紙尿褲1前後二等分之橫斷線 Β - Β更前方處寬度變窄’故較不會妨礙紙尿褲穿著者之 腳朝向前方之動作。因此’可將夾角^作成與夾角々相 等,作成1 0〜3 0度。不過,於該實施形態,也是以使夾 角7較小之方式將夾角α作成35〜60度’另一方面以使 夾角(5較大之方式將夾角々作成10〜30度時’紙尿褲1 妨礙腳之動作之情形會變得更少。於該紙尿褲1 ’在吸收 部3之臀下域部分’位於前方之非折入部分之中之線C1 一 C ]與一對虛線s間之部分3 c之擴張也變得較小’位於 ‘16- (13) 1232096 後方之非折入部分之中之線C 2 — C 2與一對虛線 分3 d之擴張也變得較大。 第7圖,爲與顯示本發明之實施形態之另一 圖相同之圖。於該紙尿褲1之吸收部3,分別從 斷線B — B之中點Μ朝向左右方向等距之橫斷線 之二點G、Η,虛線S、Τ、U及凹溝20s、20t、 側緣部分26延伸。吸收部3,於凹溝20s、20t 第4圖之紙尿褲1同樣被折彎形成折彎部5 0。 收部3,在橫斷線B — B上之點G與點Η間之部 爲腹側吸收域3 a與背側吸收域3 b之交界線。部 形成有效之折入部5 0之方式,對應紙尿褲1之 成0 m m以上之適當之長度。於部分L之長度爲 時,二點G、Η會與中點Μ —致,成爲第4圖 1 ° 本發明,除了例示於第1〜7圖之紙尿褲1 將覆蓋部2之臀下域8之寬度作成與顯示於第4 之吸收部3之寬度相同,或是作成比吸收部3之 而予以實施。此時之吸收部3,可將芯材2 1之夕ί 不透液性薄片覆蓋,將該不透液性薄片接合於覆 於該接合,將吸收部3接合於覆蓋部2之前腰圍 腰圍域7,可不接合於臀下域8。於如此接合 1,可將覆蓋部2用切除臀下域8僅具備有前腰丨 後腰圍域7者代替。以紙尿褲1爲例已作說明之 可作爲訓練尿褲、失禁患者用尿褲、生理用尿褲 Τ間之部 •例之第4 位於從橫 丨Β -
