292998 經濟部中央橾準局貝工消费合作社印製 A7 B7五、發明説明(1 ) 本發明係關於容器之端壁,特別是關於容器本體之端 壁及一藉由雙重密封來固定端壁於容器本體之方法。 美國專利案號4093102URASKA)描述容器端部包含有 一環狀蓋狀勾體,一夾壁形成於蓋狀勾體内部,一向外內 凹之環狀強化塊由該夾壁徑向地向内延伸,及一央嵌板藉 由環狀向外凸塊連接該強化塊之内壁。該容器端部能容纳 90 psi之内壓力,其藉由夾壁、凸塊外壁及内壁所形成之 斜度垂直於中央嵌板。該夾壁斜度D°是介於14°至16°間、 外壁斜度EVj、於4·、內壁斜度C°是介於1(Γ至16°間而逋至 該向外凸塊。我們發現藉由增加夾壁之斜度和限制抗凸起 凸塊之寬度可以達成金颶使用之改良。 我們歐洲專利案號0153115中描述一値製造容器端部 之方法,該容器端部是用來關閉一容器本饈,其用來容納 飲料,如啤酒等。該容器端部包含一環狀凸緣或蓋狀勾體 ;一夾壁形成於蓋狀勾體內部;一向外内凹之強化塊由夾 壁徑向地向内延伸且該強化塊從該夾壁增厚之接合處開始 延伸;一中央嵌板,其是由強化塊之内部所支撐。此棰容 器端部通常是由預先塗漆之鋁合金,如鋁鎂锰合金,如合 金 5182。 我們國際專利申請號W0 93/17864中描述一用來装載 飲料罐之容器端部,其由鋁鎂合金叠片所裂成並塗覆一層 半透明之熱塑性聚酯,此棰聚酯及鋁合金β片可使容盏端 部製成一狹窄且高強化之凸塊即可使用較便宜之鋁鎂合金 本紙張尺度適用中國國家標準(CNS ) Α4規格(210X297公釐〉 4 Α7 Β7 經濟部中央橾準局員工消费合作社印裝 五、發明説明(2 ) i 上述之容器端部是藉由夾頭之瓌狀凸緣所做之雯重密 封來固定,該凸緣之宽及离被插入抗凸起凸塊中,若狹窄 之環狀凸緣滑動,則會有磨損之危險,如此該琢狀凸緣很 容易損壊。 一容器端部的繼繙發展在於使用較少金屬,但仍可使 填充滿之容器堆積在另一容器端部上。本發明提供一容器 端部,其包含有一延國周環繞之蓋勾、一夾壁形成於蓋勾 內部、一向外内凹之環狀強化凸塊從該夾壁徑向向内延伸 、及一中央嵌板固設在該強化凸起的内部。其特微在於, 該夾壁和一垂直於中央嵌板外部之軸形成一傾斜角,其角 度在20°到60°間,且内凹凸起I±1.5iib(0.060”)窄些;更 佳的是,該夾壁之傾斜角在40°到45°間。 在容器端部之一較佳實施例中,該強化凸起之外壁和 一垂直於中央嵌板的線形成一角度,為_15>到+15"間,該 外壁高度爲2.5ma。 在一實施例中,該強化凸起有一内部和一外部,它們 互相平行,且藉由内凹半徑互相接合。 中央嵌板之直徑和環狀捲起之直徑之比例M 80¾或較 少為較隹。 此容器端部是由熱塑性聚合膜及鋁合金片所形成之叠 片所製成,如鋁锰合金Η或鐵金鼷上塗覆聚乙烯對笨二甲 酸酯薄祺所形成之叠片,若用在飲料包裝上其厚度是小於 0.010(0.25ηη)。一環狀蓋勾内放入一液墊合成物。 本發明之第二方面在提供一方法來形成一雙重密封於 Iί:——ΓI-^-裝------訂------^ (請先閱讀背面之注意事項再填寫本頁) 本紙張尺度適用中國國家標準(CNS ) Α4規格(210X297公釐) 5 經濟部中央樣準局貝工消費合作社印製 A7 B7 五、發明説明(3 ) 容器本賭和容器端部間,其方法包含下列步驟: 将容器端部之捲邊放在由底板所承接之容器本體的凸 緣上;將一夾頭放入容器端部之夾壁中Μ便使容器端部對 準容器本體之凸緣;該夾頭有一錐體狀之啟動面,其傾斜 度大致和容器端部之夾壁相等;一呈圖柱狀之外壁部份, 由啟動面向外延伸;容器端部及容器本體之組合和一第一 可蓮轉之密封滾輪間之相對轉動會形成第一個因運轉而成 之密封,且該第一運轉而成之密封和一第二可蓮轉之密封 滾輪間之相對轉動即可完成一雙重密封。在密封蓮作期間 ,該夾壁會被彎曲而和夾頭之圖柱狀外壁部份接觴。 其它不同資施例將被描述藉由例子及參考下列之圖示 其中: 第1圖係習知用來形成雙重密封裝置之簡解圖; 第2圖係容器端部及習知夾頭在密封前之放大侧剖示 画; 第3圖係習知雙重密封之局部剖示圖; 第4圏係本發明容器端部在端部捲曲前剖面側示圖; 第5圖係第四圖之容器端部在容器本體上未形成雙重 密封前之剖面钿示圖; 第6圖係容器端部及容器本體在第一次浬轉密封期間 之類似圖; 第7圖係容器端部及容器本餹在第二次蓮鹎密封而形 成雙重密封期間的類似圖; 第8圖係夾頭細部之部份剖示圖;

之夾頭5。在頂板之支撐臂7上有一第一可轉動密封滾輪 6,其可轉動向或遠離該夾頭;在頂板之一另一支撐鹫9 上有一第二可轉動密封滾輪8,其可移動向或遠離該夾頭 *在第一可轉動滾輪和夾頭上之容器端部間做相對動作後 ,第一個轉動而形成的密封就完成了。 如第1圖所示,該夾頭5夾持一棰固地放在容器本體 12之凸緣11上的容器端部10,該容器本體12是由升降板4 所支撐。在一雙重密封(如第3圖所示)形成前,該夾頭 之第一及第二轉動滾輪6、7被淸楚地顯示出來,該雙重 密封之形成是由每一滾輪所形成之密封變成容器端部及容 器本體凸緣之捲邊。 第2圖顯示放大之夾頭5及容器端部10,該容器端部 包含有環狀捲邊13, 一夾壁14形成於捲邊之內侧,一向外 延伸且内凹之抗凸起凸塊15,其由夾壁向内延伸且支撐一 中央嵌板16,該夾壁向外張開一角度C,大概12^到15·。 夾頭5包含有一本體17,其藉由環孔18固定於裝置之 其它部位(圖未示),一環狀凸塊19,由夾頭之本體17向 外凸出,使該本體17之端面形成一凹處以容纳容器端部之 中央嵌板16,該中央嵌板16可能並未很緊密地放入該環狀 凸塊19内。 本紙張尺度適用中國國家標準(CNS ) A4规格(210X297公釐) 7 ---^------^ -裝------訂------^.vi

凸起19也必須較窄,因此易破裂。而且該容器端部之部位 D很容易遭受磨損,而會在使用巴斯德式殺_法後,留下 令人難Μ接受之醮陋黑點。 第3圖顯示一典型之雙重密封之部分剖示圖,其顙示 容器端部10之勾體20和容器本體12之勾體21所形成之銜接 〇 第4圖顯示本發明之容器端部,其包含一沿圖周瓖繞 之蓋狀勾體23、一夾壁24由該蓋狀勾體23之内部軸向向内

) A7 B7 經濟部中央橾準局貝工消费合作社印裝 第4圖所示之容器端部22上的一沿圓周環境之凸緣23是放 在容器本體12之凸緣11上。 在第5圖中,一改良之夾頭30包含有一夾頭本膿31, 其有一錐體狀(frustoconical)之啟動面32和容器端部22 之夾壁24相喫合。 該錐體狀之啟動面32M軸向向外傾斜一角度,大概和 傾斜角Ce相等,在20°到6(Γ間,而M43°角為較佳。啟動 面32比夾壁24略短些。一大體上呈圖柱狀之外壁部分33, 由該啟動面32往上延伸,且傾斜一角度,大概在+4"和-4° 之間,若以夾頭之縱軸為參考點。類似第2圖所示,此改 良夾頭30亦有一螺孔Μ連接此形成雙重密封之裝置的其它 部位。 在比較第2_之夾頭,此改良夾頭30是設計來先驅動 相對較大之夾壁24,而沒有嵌入抗凸起之凸塊25中;笛夾 壁24之形狀被改變,如第6及7圖所示之第一、第二之密 封過程,夾壁24和國柱狀之外壁33會在相喫合Μ進一步驅 動。如第5圖所示,該夾頭30有一瓌狀凸塊、呈弧形剖面 ,但該凸塊並非設計來嵌入夾壁内,因此不會磨掉或磨損 在容器端部之塗覆層;就是說不會如第2圖所示,在內凹 之凸塊的表面上驅動。 由此可了解,第一悃蓮轉而形成之密封可藉由第1圖 所示之装置來完成。 第6圖顯示第一個密封過程中之改良夾頭及容器端部

夾頭30和滾輪34間,以使容器端部之夾壁變形(如圖所示 )° 在完成第一値密封過程後,第一可運轉滾輪被摒動離 開第一形成密封,然後第二可蓮轉滾輪38被搌動向内推靠 由夾頭30所支撐之第一形成密封。第二可蓮轉滾輪38和 第一形成密封間之相對轉動會完成一雙重密封,如第7圖 所示,而藉由第二可蓮轉滾輪38和夾頭30間之夾持壓力Μ 緊迫此雙重密封,此時夾壁24之上半部是以大體上直立之 狀態固定在容器本體之上緣部位。 本發明之容器端部是由鋁合金5182和鋁合金3004/聚 合物之叠片所形成,其由CarnaudMetalboxM商棟ALULITE 所販賣。每一容器端部是藉由雙重密封固定在DWI (drawn and wal 1 i roned)之容器本體;如.表1所示,使用不同夾 頭角度及夾頭外壁角度,然後記錄容器端部所能承受容器 内部壓力之程度: -----^-----^ I
