Description

1222856 A7 B7 五、發明説明（1 ) 技術範圍 一種用於以吹塑製成之具有蓋的雙重壁容器。 發明背景 以吹塑製成之雙重壁樹脂本體及蓋在填充一絕緣材料時 可作爲絕緣容器。位於該本體與蓋之間的一鉸鏈允許該蓋 旋轉打開以接近該容器内部，且至少一部份該鉸鏈係較佳 地在生成該本體及該蓋之該吹塑製程中形成。 當一以吹塑製成之雙重壁本體及蓋填充絕緣材料之後， 該蓋將變得更重，這使得該鉸鏈支持該蓋相對該本體作旋 轉運動者需強健且耐久，以致於在產品使用壽命期間不致 失去作用。對於這種以吹塑製成之鉸鏈而言，絕緣容器亦 必須滿足許多其他需求，包括低製造成本、組立容易、動 作可靠、及防止消費者誤用。 鉸鏈已藉由在該本體或蓋中鑽出凹孔，使得嚙合該等孔 洞之凸起件可押扣入位置中而得形成於以吹塑製成之雙重 壁容器中。基於眾多原因，這對於將填充一防火絕緣材料 之一容器而言係無法接受的。這種絕緣較佳地係可傾注入 該容器與蓋之中間壁空間中且於稍後凝固成一固態。由於 鉸鏈凸起件無法在一絕緣材料變爲固態時旋轉，因此無法 僅延伸通過凹部孔而進入一雙重壁容器之中間壁空間内。 必須將嵌入物配置於該等鑽孔中以接收該等凸起件且自與 該絕緣材料之任何連結處分離該等凸起件，但這需要額外 部件且必須定位該等部件來完成鉸鏈組立。 另一嚴重問題在於，鑽入中間壁空間内以收容鉸鏈凸起 -4- 本紙張尺度適用中國國家標準(CNS) A4規格（210 X 297公釐） 1222856
件37及38内側，台面區41及42最好具有自正圓柱形偏離 之一略微錐形。一極小角度之一錐形推拔足以達成此且輔 助確保不致因陷於凸起件3 7及3 8内之中間壁空間内的空氣 而在該絕緣材料中產生空隙。較佳地係將使用之任何錐形 推拔平均地施加至凹部2 7及2 8，使得可沿台面區4 1及4 2 整個軸向長度產生介於該兩者間的嚙合。 凸起件及凹部3 7及3 8亦較佳地具有嚙合相對應半球形凹 邵區域44之略微圓形或半球形末端區域43。這些有助於凸 起件3 7及3 8押扣入凹部27及28而與其達成組立關係。圓 形或半球形外型亦在該蓋相對於該本體之鉸鏈旋轉期間， 輔助保持該等凸起件與該等凹部的軸向對正。 調整鉸鏈凸起件37與38以及凹部27與28之大小尺寸成爲 較佳者’則可把在蓋3 0及本體2 0 %充絕緣材料之前將凸起 件37及38押扣入凹部27及28中。押扣結合該等鉸鏈部件 包括以相對鉸鏈軸45夾一角度地放置其中一凸起件37或38 至鳴合其中一凹部27或28 ’且接著再操縱蓋3〇及本體2〇 而以對正鉸鏈軸45地押扣另一凸起件進入另一凹部中。 該鉸鏈之押扣組立較佳地係當凹部2 7及2 8仍保持吹塑之 溫熱時完成。以吹塑製成之部件通常係在自一模具脱出後 而冷卻時收縮。最好在形成凹部27及28之容器部件已冷卻 且完成收縮之前即將蓋30及本體20押扣結合。儘管仍保持 來自一模具之溫熱，但本體20將使其凹部27及28稍微更加 分離’且該等者較該邵件已冷卻至室溫後之凹部稍微更具 撓性。 -9- 本紙張尺度適用中國國家標準(CNS) A4規格（21〇x 297公f) 1222856 A7 Γ--~____ Β7 五、發明^? 5" ~~~ 藉由使具有凸起件37及38之蓋30自該模製程序冷卻至較 蓋30所組立之本體2()更爲冷卻，將有助於押扣結合該鉸鏈 。一冷卻之蓋3 〇將自其離開該模具時之尺寸收縮一些，使 其可更輕易、損害風險較低地將冷卻之凸起件3 7及3 8押扣 入溫熱之凹部27及28中。 亦可能在蓋30及本體20兩者皆爲剛才由一模具取出且皆 保持該模製程序之溫熱時，將凸起件3 7及38押扣入凹部27 及2 8中。儘管當完成這種押扣組立時，並無任何部件已大 幅收縮’但該兩部件在溫熱時皆較稍後已冷卻者更具撓性。 當蓋30押扣組立至本體2〇之後，該蓋及該本體將繼續冷 卻及收縮’直到其到達室溫爲止。該等者之較佳結構係允 許其一同收縮，使得互相連接之大小尺寸保持互相相對地 穩足。換言之，即使蓋3 〇及本體2 〇可在組立後收縮，但其 仍保持鉸鏈式連接。 當本體20及蓋30已如圖6中所示者模製且押扣結合之後 ’將亦如同圖6中所示者填充經由填充開口 25、26、35及 3 6傾注入之一絕緣材料。該絕緣材料係流入且填充本體2〇 及蓋3 0兩者之中間壁空間且於稍後凝固而形成一固態材料 5〇 ’如圖5所示。除了通常填充本體2〇及蓋3 〇之所有中間 壁之間以外’固態材料50亦填充包括凸起件37及38後方之 空間及環繞凹部27及28之空間等鉸鏈區域24及34。如此 可堅硬化且使該本體及該蓋之壁21、22、31及32、以及 凸起件3 7及3 8與嚙合凹部2 7及2 8之間的鉸鏈連接強硬， 如圖5中之最清楚顯示。 -10- 本紙張尺度適用中國國家標準(CNS) Α4規格(210 X 297公釐）
