具拉伸,且進而該預成形體相對模具的内表面被吹塑成所 需形狀。 在一些情況中,希望使一蓋元件附接至此種吹塑容器。 在WO 2008083782中,一容器被揭示成具有一閥組合 件,藉由使用一熔接方法,諸如超音波熔接或雷射熔接被 提供在一頬部。此閥組合件在吹塑該容器之後被熔接至該 頸區。 在WO 2008098937中,一容器被揭示成具有一閥組合 件,藉由使用一炼接方法被提供在一頸部。此閥組合件在 π人塑谷器之後,藉由將一雷射束經由頸部之一壁導向該閥 組合件的一環狀部份上而被炼接至該頸部區域。 【發明内容3 希望提供一替代方法及預成形體,用於製造具有一附 接之蓋元件的吹塑容器。 3 201103719 本說明的一第一層面是關於一種用於吹塑一容器的預 成形體,其中一蓋元件在一容器由該預成形體吹塑之前被 附接於該預成形體。 本說明的另一層面針對一種用於由一預成形體吹塑一 容器的方法。該方法可包含首先將一蓋元件附接於預成形 體且進而由預成形體吹塑該容器的步驟。 本說明的又一層面針對一種容器,由本說明的一預成 形體或使用依據本說明的方法步驟被吹塑。 預成开> 體及方法的其他層面被進一步揭露於依附請求 項中。爲了進一步闡明此揭露之標的,一預成形體、方法 及容器的實施例在下文中參照僅為示意圖的諸圖式被揭 露。在此等圖式中: 第1圖示意繪示一預成形體的一第一實施例; 第2圖以截面圖及部份底視圖示意繪示一蓋元件; 第3圖示意繪示具有一蓋元件附接在頸部的第丨圖預成 形體; 第4圖示意繪示一預成形體的一第二實施例; 第5圖示意繪示一預成形體的一第三實施例; 第6圖示意繪示一預成形體組合件; 第7圖示意繪示另一預成形體組合件; 第8圖示意繪示依據本說明製造的一容器;及 第9圖示意繪示依據本說明製造之具有連接裝置的一 容器的一供選擇實施例。 【實施方式3 4 201103719 在此說明中,實施例是描述有關由一預成形體吹塑, 諸如拉伸吹塑的塑膠容器,其中一預成形體可例如藉由射 出成形或擠壓被製作。此等容器可被用於例如但不限制於 儲存飲料,諸如但不限制於碳酸飲料。顯然該等容器可由 其他材料製成,諸如塑膠摻合物,塑膠與金屬,諸如金屬 箔、脫氧劑等等的組合物。該等實施例僅作為示範性實施 例被揭露,且並不視為以任何方式限制本揭露。 在此揭露中,吹塑必須被理解成至少包含但不限制於 拉伸吹塑,其中一預成形體被加熱,縱長拉伸,且被吹塑 成一所需形狀。在縱長拉伸期間,該預成形體可能已經被 在吹塑至某一程度。 在此說明中,一預成形體,也可以是一型坯必須被理 解成至少包括但不限制於一由塑膠射出成形的元件,將被 吹成一吹塑容器。在此說明中,預成形體應被描述用於吹 塑基本上具有一瓶狀,包括一頸部、主體部及一底部的容 器,但對任一該技藝中具有通常知識者而言,很明顯,不 同形狀容器可使用在本發明概念内的不同形狀的預成形體 製成。一預成形體可以是單層或多層的。一多層預成形體 可使用習知技術被製成,諸如但不限制於共射出成型、共 擠壓或重疊模製。一多層預成形體可具有一剝離層或多剝 離層。 在此說明中,類似大約及實質上等用語應被理解成意 指提及之一給定值的變化在給定界限内是允許的,變化可 以是給定值的至少5%,較佳地至少10%,且更佳地至少 15%。 15%。201103719 在此說明中,預成形體及容器將被討論由PET或PET摻 合物製成。然而,依據本揭露之預成形體及容器也可由不 同材料,材料之摻合物或組合物製成,諸如但不限制於聚 丙烯或聚苯乙烯、PEN、聚乙烯、聚碳酸酯、PBT,上述之 摻合物或其之組合物。在PET或PET摻合物的情況中,標準 PET必須在此層面上被理解成至少包括未加入添加劑的 PET,用於防止PET在形成諸如一預成形體的射出成形期間 結晶。 在此說明中,應參考用於容納及施給飲料,尤其是碳 酸飲料諸如啤酒及清涼飲料的容器。然而,其他容納物可 使用一依據此說明的容器被儲存及施給。 在本揭露中,預成形體可與一可被拉伸吹塑成一容器 的塑膠材料形成,該容器具有一相對上的薄壁或組合壁, 其中該預成形體實質上是非晶態的,而瓶子至少部份結 晶。較佳地,該預成形體由實質上無防結晶添加劑,諸如 乙二醇的一材料形成。已認識到此等添加劑在射出成形一 實質上非晶態的預成形體中可能是有利的,但是此等添加 劑仍留在該吹製容器中,這對容器的強度及/或剛性是不利 的。諸預成形體較佳地被射出成形具有一實質上小到足以 防止塑膠材料結晶的壁厚。 對於由一預成形體拉伸吹塑,具有一内部體積,特別 是一大於3公升體積的容器,一預成形體之開口應相對較 大,例如2公分或更大。提供一具有一較小開口覆蓋元件; 201103719 能使一具有較小尺寸的閥或閥組合件易於配置。例如,當 標準喷霧類型閥、噴霧罐型閥等等被使用,例如被夾固時, 這是有利的。 在第1圖中,一預成形體1被繪示成以一通常習知的方 法被射出成形。第1圖之左側以截面’右側以側視圖繪示預 成形體1。預成形體1可具有一實質上圓柱狀壁2,其具有一 封閉第一端3及一在相對第二端5上之頸部4。一内部體積6 從一頸部開口 7延伸至一内部空間8。内部空間8主要由一内 表面9界定。圍繞内部空間8的壁2可具有一厚度1^,其可例 如等於或大於頸部4的厚度Tn。在頸部4的一外側10可提供 抓握元件11,例如一或二凸緣12 ’及/或螺紋13。該一或每
