1247715 A7 B7 五、發明説明(1 ) 【技術領域】 (讀先閲讀背面之注意事項再填寫本頁} 本發明係關於,具有以2軸延伸吹製成形而形成的容 器本體之合成樹脂製容器本體,以及將被2軸延伸吹製成 形之預型加以成形爲該容器本體之模具裝置。 【背景技術】 爲了防止寶特瓶等飮料用容器在店面被不當地開啓, 通常,會在瓶蓋的邊緣下端透過可斷裂之斷裂部,一體地 設置不當開啓防止環。 此輪在內周圍面具有突片,若將蓋子往開栓方向轉動 ,使其對容器本體而上昇,則輪的突片會卡止於突設在容 器本體瓶口部外周面之突條,阻止輪的上昇,但是,因爲 蓋子繼續上昇,故位於與蓋子之間的斷裂部會斷裂,蓋子 及輪分離,因此可依發判別此分離而確認容器是否已經被 開啓。 經濟部智慧財產局員工消費合作社印製 另外,爲了防止飲料用容器在開栓狀態時內容物外漏 及外氣流入,故在瓶蓋內面安裝襯墊以提高氣密性,但是 ,此襯墊係由具有適度彈性的材料所製成,藉由瓶蓋與容 器本體瓶口部之間鞏固的螺合,其被壓至瓶口部上端面, 並由於與該瓶口部上端面密接,而密封瓶口部的開瓶口部 〇 然而,在附有不當開啓防止環的瓶蓋中,自螺合限, 至輪的突片卡止於容器本體瓶口部的突條而開始斷裂部的 斷裂之間,隨著面對容器本體瓶口部之蓋子的上昇變位, 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) -5- 1247715 A7 B7 五、發明説明(2 ) (請先閲讀背面之注意事項再填寫本頁) 壓附襯墊至瓶口部上端面的力量減弱,故若在店面於斷裂 部未斷裂的範圍內轉動蓋子,則雖然以肉眼觀之是沒有異 常’但實際上已變成襯墊的密封機能降低之狀態,這樣的 狀態下’容易產生內容物變質,亦將帶給消費者莫大地不 安。 作爲改善此不良情況的手段之一,係思考著將容器本 體瓶□部的外周面製成密封面,但是此瓶口部外周面,在 丰皮2軸延伸吹製成形之預型的射出成形爲容器本體時,在 環繞此預型外周面的全高範圍且被形成之分模線上,係形 成突出高度低的縱突條狀毛邊73 (以下,參照第8圖) ’因此,即使欲使襯墊74密接於瓶口部外周面,由於在 彈接至該毛邊73的部分形成間隙75,所以結果造成蓋子 的開栓(漏出)角度變小而產生無法充分地發揮密封機能 之可能性。 經濟部智慧財產局員工消費合作社印製 作爲另一個手段,於日本特開平11 一 1 80458號揭示 著將容器本體瓶口部的內周面製成密封面之構想,但是此 以往技術係記載著附有不當開啓防止環的蓋子(參照第7 圖),其中:在襯墊53的下面將與容器本體5 1的瓶口部 內周面緊密且深入嵌合之圓筒狀的嵌套54加以垂下,並 將此嵌套54與瓶口部內周面之間的可密接之距離增長, 藉由此,在斷.裂部55不斷裂的範圍內,即使轉動蓋子52 亦可維持氣密性。 然而,在上述之以往技術中,襯墊53的嵌套54,係 以緊密嵌入容器本體51的瓶口部般地,將其外徑製成比 本紙張尺度適用中國國家標準(CNS ) A4規格(2】0 X 297公釐) 1247715 _ B7___ 五、發明説明(3 ) (請先閱讀背面之注意事項再填寫本頁) 瓶口部的口徑更大,且更高尺寸地被成形,故在蓋子52 螺合時,在襯墊5 3與容器本體5 1的瓶口部之間相互位置 有些許位移的情形下,嵌套54會碰撞到瓶口部上端面, 而會產生以嵌套54被彎曲之狀態安裝之虞,而在這樣的 安裝狀態下將會有容器無法具備密封性的問題。 因此,本發明係鑑於上述問題所製造之物,以讓容器 本體瓶口部的外周面上端部與襯墊的密接狀態達到環繞全 周面之情況作爲技術課題,且即使轉動蓋子,在一定角度 範圍內亦可充分地確保其氣密性,提供使蓋子的開栓角度 安定化之合成樹脂製容器本體,及可簡單且廉價地取得被 2軸延伸吹製成形爲該容器本體之預型爲目的。 【發明的開示】 在解決上述課題之本發明中,申請專利範圍第1項所 記載的發明手段爲,在瓶口部的外周面處形成有將陽螺紋 開設成瓶狀,將瓶口部的外周面上端部形成爲,環繞全周 無形成分模線且無凹凸之光滑的密封面。 經濟部智慧財產局員工消費合作社印製 在此申請專利範圍第1項所記載的發明中,容器本體 ,由於係將瓶口部的外周面上端部形成爲環繞全周無形成 分模線且無凹凸之光滑密封面,故密封面與襯墊的圓筒部 係以環繞全周.面且無間隙之狀態加以密接,使藉由蓋子密 閉的容器本體安定而達到堅固。 申請專利範圍第2項所記載的發明,係爲在申請專利 範圍第1項所記載的發明構成中增加:在容器本體的瓶口 ^尺度適用中國國家標準(CNS ) A4規格(210X297公釐]~~ 1247715 A7 B7 五、發明説明(4 ) (請先閲讀背面之注意事項再填寫本頁) 部之外周面上端部,突設有比產生於分模線上之毛邊更高 的突出高度且突出於外方之周條突部,將該周條突部的外 周面做爲密封面。 在此申請專利範圍第2項所記載的發明中(以下,參 照第6 ( i )圖),在自容器本體瓶口部4的外周面形成 突出至外部之毛邊20時,藉由此影響,密封面8的下端 部無法與襯墊丨6的圓筒部1 8密接,此情形將使密封機能 降低,但是因爲突設具有較毛邊20更高的突出高度之周 條突部19,並將其外周面做爲密封面8,如第6 ( ii )圖 所示,可以使密封面8的全區域與襯墊1 6的圓筒部1 8密 接,而充分發揮密封機能。 申請專利範圍第3項所記載的發明,係在申請專利範 圍第1項或第2項記載的發明之構成中增加:將密封面的 軸方向長度設定爲,比具有陰螺紋且被螺合至容器本體瓶 口部之有頂圓筒狀蓋子內面襯墊的軸方向可密封長度更長 〇 經濟部智慧財產局員工消費合作社印製 在申請專利範圍第3項所記載的發明中,即使在店面 蓋子被不當轉動,因爲將密封面的軸方向長度設定爲:比 具有陰螺紋且被螺合至容器本體瓶口部之有頂圓筒狀蓋子 內面襯墊的軸方向可密封長度更長,故在一定角度範圍內 仍可確實地維.持容器本體的密封,且維持蓋子的開栓角度 於既定的狀態。 申請專利範圍第4項記載的發明,係在申請專利範圍 第3項所記載的發明構成中增加:將密封面的軸方向長度 本紙張尺度適用中國國家標準(CNS ) A4規格(210X 297公釐) -8- 1247715 A7 B7 五、發明説明(5 ) ^定爲’比在透過斷裂部被一體設置於蓋子之不當開啓防 止環的斷裂開始前,之蓋子的上昇距離更長。 在此申請專利範圍第4項所記載的發明中,即使在店 ®蓋子被不當轉動於斷裂部未斷裂的範圍內,因爲密封面 白勺軸方向長度被設定爲:比不當開啓防止環斷裂部的斷裂 開始前之蓋子的上昇距離更長,故對於蓋子在一定的上昇 距離內’容器本體的密封可確實地被維持,且可維持蓋子 的開栓角度於既定之狀態。 本發明中,申請專利範圍第5項記載的發明之手段, 係針對, 將形成瓶狀容器本體之第一次成形品的預型內側面之 圓柱狀模具面的前端部製成半球面狀的芯型,以及由連接 於該芯型基端之平板狀芯板所形成之芯模,與形成預型外 側面的模具面之一對對合模所構成之凹模,所構成之模具 裝置,其特徵爲: 前述芯板,係在芯型的周圍以平斷面凹設圓環狀的溝 狀凹部。 在此申請專利範圍第5項所記載的發明中,係爲,無 使用新的模具構件,而將溝狀凹部加工形成於既有的芯板 中,之簡單的結構,在被2軸延伸吹製成形爲容器本體時 ,可以直接將.成爲密封面的部分,簡單、正確且安定地形 成爲預型。 申請專利範圍第6項所記載的發明,係在申請專利範 圍5所記載的發明構成中增加:將溝狀凹部的開口端外徑 本紙張又度適用中國國家標準(CNS ) A4規格(210X297公釐) (請先閱讀背面之注意事項再填寫本頁) 裝· 訂 經濟部智慧財產局員工消費合作社印製 -9- 1247715 A7 _____ B7 五、發明説明(6 ) 製成,比在凹模的開口邊緣之口徑再加上分模線上的毛邊 之突出高度的二倍數値還要大的外徑。 (讀先閲讀背面之注意事項再填寫本頁) 在此申請專利範圍第6項所記載的發明中,係爲,將 加工成形爲芯板之溝狀凹部的開口端的外徑製成,比在凹 模的開口邊緣之口徑再加上發生於分模線上毛邊之突出高 度的二倍數値還要大的外徑,的簡單結構,故在被2軸延 伸吹製成形爲容器本體時,可以直接將成爲周條突部的部 分,簡單、正確且安定地形成爲預型。 【發明之最佳實施形態】 以下,根據第1圖至第6圖說明本發明之實施型態。 經濟部智慧財產局員工消費合作社印製 第1圖係顯示本發明之第一實施型態,爲顯示將依據 本發明製成之容器本體2及蓋子3加以組合之合成樹脂製 容器1的瓶口部之縱剖面圖,此合成樹脂製容器1係由: 以聚對苯二甲酸乙二醇脂製的2軸延伸吹製成形品作爲容 納飲料之主要瓶狀之容器本體2,及以聚乙稀、聚丙稀等 烯烴類樹脂製射出成形品作爲被嵌狀地螺合安裝至此容器 本體2之蓋子3,所構成。 在容器本體2的瓶口部4之外周面處,由上開始依序 設置:環繞全周無形成分模線且無凹凸之光滑密封面8、 陽螺紋5、中止輪6及頸輪7。 蓋子3自圓盤狀的頂盤9之邊緣處始,將圓筒狀的裙 帶1 0垂下,此邊裙帶1 0將內周面上端部分朝向內側,形 成爲厚實的襯墊裝著筒部1 5,在做爲此襯墊裝著筒部1 5 本纸張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) -10- 1247715 A7 B7 五、發明説明(7 ) (請先閲讀背面之注意事項再填寫本頁) 的下位之內周面部分螺設與陽螺紋5螺合之陰螺紋11’ 透過可斷裂的斷裂部13 —體設置不當開啓防止環12於下 端。 此不當開啓防止環12,在其內周面處,以將蓋子3 打栓安裝於容器本體2的瓶口部4的狀態,將前端朝斜上 方延伸,複數個的突設自下方卡止於中止輪6之係止片 14 ° 被黏著於蓋子3之軟質彈性材質的襯墊1 6,係爲由 :覆蓋蓋子3的頂板9下面全體之圓盤狀的水平部17 ; 以及自此水平部1 7的邊緣沿著襯墊裝著筒部1 5的內周面 垂下,並以蓋子3被螺合安裝於瓶口部4的狀態,利用襯 墊裝著筒部1 5自外側支撐,形成由被押住密接於瓶口部 4的密封面8之圓筒部1 8,所構成之有頂圓筒狀。 經濟部智慧財產局員工消費合作社印製 在合成樹脂容器1的閉蓋狀態中,由於是在以襯墊裝 著筒部1 5支撐其外周面的狀態,押壓密接襯墊1 6的圓筒 部1 8於可能被形成於分模線上之毛邊20等的無凹凸且光 滑的密封面8,故容器本體2的密封被確實地維持,蓋子 的開栓角度亦被維持於既定的狀態。 在合成樹脂製容器1在最初開放時,由於一旦將蓋子 3往螺脫方向轉動,則蓋子3上昇,不當開啓防止環12 的卡止片14前端將卡止至中止輪6的下端處,故雖然不 當開啓防止環1 2被阻止上昇,但是因爲蓋子3持續上升 ,故斷裂部1 3仍被扯掉般地斷裂,自蓋子3分離。 消費者藉由確認不當開啓防止環1 2是否自蓋子3分 本紙張尺度適用中國國家標準(CNS ) A4規格(210X297公釐) -11 - 1247715 A7 B7 五、發明説明(8 ) 離,可在購買前判斷合成樹脂製容器丨商品是否在店面被 不當地開啓了。 且’如第2圖所示,將蓋子3朝螺脫方向轉動,即使 在店面於斷裂部 13不斷裂的範圍內不當地轉動蓋子3, 因密封面8上無毛邊20等的凹凸,故可防止襯墊1 6的損 傷,維持合成樹脂製容器1的氣密性。 其次,於以上的實施型態中所述,依據第3圖,將2 軸延伸吹製成形之預型的成形模具裝置之一例,說明於將 無分模線的密封面8形成於瓶口部4外周面上端部之容器 本體2 ’但是,第3圖係顯示將容器本體2的第一次成形 品之預型加以成形之模具裝置31的重要部位,此模具裝 置31係由芯模32及凹模33所構成的。 芯模32,係由:將形成預型的內側面型面之圓柱狀 ’的前端部製成半球面狀之芯型34,及連接至該芯型34 的基端之平板狀的芯板35,所構成;芯板35在芯型34 的周圍以平斷面凹設圓環狀的溝狀凹部36。 凹模33,係由,形成預型的外側面型面之一對對合 模,所構成;於前端側設有注入口 37。 在預型射出成形時,將芯模3 2及凹模3 3定型,形成 成爲預型形狀之凹部3 8後,自注入口 37射出溶融合成樹 脂材料而成形預型。 成爲容器本體2的瓶口部之預型的瓶口部’由於是以 圓環狀的溝狀凹部3 6成形含有其外周面之開口端部’故 在其外周面上端部不會形成分模線,因此完全沒有會在外 本紙張尺度適用中國國家標準(CNS ) A4規格(210 X 297公釐) — (请先閲讀會面之注意事項再填寫本頁) •訂 經濟部智慧財產局員工消費合作社印製 1247715 A7 B7 五、發明説明(g ) 周面上端部形成毛邊20之虞。 射出成型後,預型自模具裝置3 1離型,以2軸延伸 吹製成形而成形爲容器本體2,但此時,因爲預型的瓶口 部不會變形,而直接變成容器本體2的瓶口部4,故無分 模線的開口端部之外周面上端部,就直接變成密封面8。 其次,根據第4圖說明本發明之第二實施型態。 在第二實施型態中,於容器本體2的瓶口部4之外周 面上端部,突設突出於外部之周條突部19,此周條突部 1 9的外周面內,將上端部製成朝下擴徑之傾斜面,並將 剩下的部分製成密封面8。 在第一實施型態中之密封面8下端部附近與襯墊1 6 的圓筒部8之接觸狀態,係如第6 ( i )圖所示,在形成 毛邊時,押入已突出之毛邊20,圓筒部18的一部份將自 密封面8的下端部表面浮上而產生空隙21,因此,密封 面8的下端部無法發揮密封機能,有無法使密封面8全區 域有效地產生密封機能的可能性。 另一方面,將除去突周設於瓶口部4外周面上端部之 周條突部1 9的上端部之外周面作爲密封面8的第二實施 型態中,如第6 ( ii )圖所示,因密封面8全區域比毛邊 20位於更外方,故密封面8不會被毛邊20影響其全區域 ,使其因襯墊.1 6的圓筒部1 8而變得更有力地密接,藉由 此,使密封面8全體變的有效地產生密封作用。 又,周條突部1 9的外周面上端部,由於成爲朝下擴 徑之圓錐狀的傾斜面,故在蓋子3安裝時,圓筒部1 8的 本紙張尺度適用中.國國家標準(CNS ) A4規格(210X297公釐) I---------I (請先閲讀背面之注意事項再填寫本頁) 訂 經濟部智慧財產局員工消費合作社印製 -13- 1247715 A 7 __B7 五、發明説明(10 ) 下端不會掛上並捲入周條突部1 9,可以安全地進行面對 瓶口部4之蓋子3的安裝處理。另,周狀突部19的外周 面上端部形狀,雖然是以如圖示之向下擴徑的圓錐狀爲適 合,但不限於此,如:對上端面將側壁製成垂直面之形狀 等亦可採納。甚至,也可採用:取代突出於外方的周狀突 部1 9,將容器本體2瓶口部4的外周面上端部製成向內 突出之段部之形狀。 其次,,依據第5圖,將被2軸延伸吹製成形之預型 的成型模具裝置的一例,說明於第二實施型態的容器本體 2處,但第5圖係顯示,成形容器本體2第一次成形品的 預型之模具裝置3 1的重要部位,此模具裝置3 1係由芯模 32及凹模33所構成,芯模32係將溝狀凹部36的開口端 外徑製成比凹模3 3的開口邊緣3 9 口徑更大徑,‘且,將溝 狀凹部36外側溝面的溝底側端部朝開口端擴徑。 由於芯模32的溝狀凹部36,構成預型的瓶口部開口 端部之成形型面,故在包含瓶口部外周面上端部之預型的 瓶口部開口端部的表面處,不會形成分模線。 再者,僅將溝狀凹部3 6的開口端外徑製成比凹模3 3 的開口邊緣3 9 口徑還要大外徑,則無須使用專用的模具 構件,即簡單地構成,將以外周面製成密封面8之周條突 部1 9加以成形之型部分。 【發明之效果】 本發明係爲上述之構成,茲述其效果如下。 氏張尺度適用中國國家標準(CNS ) A4規格(21〇 Χ;297公釐) ' " (請先閲讀背面之注意事項再填寫本頁) 装·
