1277582 % 、 (1) 九、發明說明 【發明所屬之技術領域】 本發明係關於容器,特別是關於供熱飮料或類似物用 的絕緣谷器、一種製造該等容器的方法、和種用於製造該 等谷ϊ&的設備、。 【先前技術】 ® 在習知技藝中,有許多具有絕緣特性供使用於例如咖 啡 '茶、湯或類似物之熱液體容器的例子。在美國1;8-八-2,266,828、US-A-4,007,670、US-A-5,145,107、US-A-5,460,323、US-A-5,524,817、US-A-5,685,480、和118-八-6,663,926專利案中可找到例子。這些容器中的每一個包 括由一空氣間隙分開的一內杯體和一外殼體。在此類型的 現代容器中,該杯體是由內側塗覆有聚乙烯樹脂或類似物 的薄紙板製成。藉由在頂部和底部的策略性位置膠黏、或 • 者在一些最近的例子中藉由熱密封,而將杯體和殼體固定 在一起。藉由各種構造的間隔件,可維持杯體壁和殼體之 間的空氣間隙。 【發明內容】 本潑明的目的再於提供一種改良的絕緣容器、製造該 容器的方法、和供製造的一種設備,使得藉由簡單方式的 改良結合(黏合)方法,能改善杯體和殼體間的結合(黏 合)。 -4- 1277582 、 (2) 藉由具有第1請求項之特徵絕緣容器、具有第1〇言靑 求項之特徵的製造該容器的方法、或具有第15請求I胃之^ 特徵的結合(黏合)設備,來實現前述和其他目的。 可熱密封的塑膠塗層設在該殻的內側或該杯體的#彻j 兩者其中至少之一,且在加熱塗層並將杯設於殻內之後, 藉由塑膠塗層用以將殻結合於杯的結合點和/或結合區_ 中至少之一,只局部地形成在對應的接觸路徑上。此“胃 • 觸路徑”通常是實質上的接觸路徑,當杯設在殻內時,杯 體的外表面和殼的內表面可在該路徑形成接觸。但是並γ 需要在殼和杯體的對應壁沿著全部周圍有實際的接觸,胃 觸路徑可只沿著部分周圍延伸,其中對應的結合點和/ ^ 結合區位於該路徑內。藉由對應的方法,那些結合點和/ 或結合區只局部形成。至少在位於該接觸路徑內的該等,結 合點其中之一和/或該等結合區其中至少之一,將殼和杆: 壁壓在一起。 ® 在將杯插入殼內之前,對應的熱可密封塑膠塗層先溶 化,然後藉由該塗層硬化後,將兩者在對應的結合點和/ 或結合區相結合。 當然接觸路徑也可能是環狀路徑,該路徑也可完全圍 繞杯體和殼,也可在直立方向有某些延伸。該直立方向意 指垂直於對應的圓周方向。 當只用於在組合、包裝、定位(nesting )或類似地處 理容器期間防止內杯掉失時,只使用一個結合點或結合區 是足夠的。在對應的熱飲料或類似物充滿容器內之後,主 -5- 1277582 ‘ (3) 要藉由對應飲料的重量將內杯保留在殼內,所以對應結合 點或結合區只需提供很少的結合力。 然而也可能藉由例如提供沿著接觸路徑而形成的多個 結合點和/或結合區,且藉由接觸路徑的無結合區而使全 部的結合點和/或結合區彼此分離,以更穩固地將杯體和 殼彼此固定。再者,結合點和/或結合區可並列地配置, 且在接觸路徑內的水平和/或直立方向彼此分離。此意味 • 者單一的結合點或結合區配置在水平或直立方向,或意味 者該等結合點或結合區例如配置在直立方向而形成一群, 且該等群然後在水平方向或圓周方向並列配置。 也可能提供對應的結合點和/或結合區在圓周方向均 勻配置。爲了改善容器的組合和對應的製造方法,如果對 應的點或區域均勻地配置是有優點的。 對應的絕緣容器具有位於容器下段之杯壁和殼壁之間 的間隙,且通常空氣間隙應維持在無熱傳連接。結果,在 • 杯體的環狀上壁段和該殼的實質上圓筒段之間,形成對應 接觸路徑是有利的。在容器的此部分中,不需對應間隙, 因爲接觸路徑配置在比塡注入容器內的飲料位準更高。 也可能將該等結合點和/或結合區配置在立即鄰接於 該杯體之環狀上壁段的下邊緣,該處形成有上肩部。間隙 從該上肩部的下方開始。 不同的材料可供殼或杯之用,該等材料其中至少之一 可由對應的塑膠材料製成。爲了回收的理由,杯和/或殻 也可能由紙板製成。爲了獲得至少杯的足夠流體密度,用 -6 - 1277582 . (4) 以形成杯的對應紙板塗覆有上述聚乙烯樹脂或類似物。當 然,也可以熱可密封塑膠塗層來塗覆紙板’其中該塗層可 塗覆在杯壁的外側、殼壁的內側、或也可配置在那兩種壁 上。 對應的結合點或結合區可具有不同的形狀,例如結合 點可爲圓形、矩形、或其他截面。對應的結合區可具有短 帶的形狀,其中該帶可水平地配置,或也可相對於圓周方 癱 向呈傾斜。 爲了溶化對應的塑膠塗層,只局部加熱就夠了,但是 也可能完全加熱例如呈環形帶塑膠塗層。 爲了獲得足夠的力量以將杯壁和殼壁壓在一起直到熱 可密封塑膠塗層再度硬化,具有至少一徑向可位移或突出 的按壓構件之環形第一構件,能被設在杯體的內側,該按 壓構件壓抵一外部第二構件,以藉由該兩構件將杯體壁和 殼壓在一起,以形成一個以上的結合點和/或結合區。當 # 然也可能對應的複數按壓構件爲外部第二構件的一部分, 或者那些按壓構件設在該兩構件上。 也可能該等按壓構件不直接接觸容器的複數壁其中之 一,而是按壓構件將例如圓形且可撓曲的環從環的內側變 形,且在外側具有變形部的該環和其他構件合作,將杯體 壁和殼壓在一起。 用以將一外殻和內杯結合以形成一絕緣容器的設備, 該絕緣容器供熱液體或類似物之用,該設備包含:該第一 構件,配置在該內杯之內;該第二構件,和該第一構件同 1277582 、 (5) 心且配置在該外殼的外側;和至少一徑向突出或可運動的 按壓構件,以將相對的殻和杯壁壓在一起,以沿著殼和杯 的周圍形成一個以上的結合點和/或結合區。 第一構件可爲插入杯體內的一圓環或一盤,該圓環或 盤可支撐對應的按壓構件或複數按壓構件,使他們在徑向 可運動。 該可運動的按壓構件的一簡單實施例是一柱塞,其被 φ 該第一和/或第二構件運動地支撐。 爲了獲得均勻分部的結合點或結合區,對應數目的徑 向可運動的按壓構件,也沿著該第一或第二構件的周圍均 勻地配置。 爲了在將杯體插入之前先配置殼,該設備包含一接收 構件,該接收構件具有用以固持該殼的至少一裙部和一上 凸緣是有優點的。 爲了使用對應的接收構件也做爲第二或外部構件,一 # 反壓延伸部可能從接收構件的上凸緣在實質直立方向延伸 。然後,對應的可運動按壓構件可爲第一或環形構件的一 部分,且不需第二或分離構件。 也可能使用供將杯體固持在預定位置的接收構件,其 中此可瞭解爲反壓延伸部的上端用做供杯體之外捲邊用的 支座。 本發明包括容器的結構、製造容器的方法、和用以製 造的對應設備,多多少少例示於圖中。 -8- 1277582 • (6) 【實施方式】 現在參考圖示’特別是圖1-3,本發明第一型式的具 體化特徵構造熱飲料容器通常例視爲〗〇,本發明的容器包 括肷在一起且彼此點結合(黏合)的一內杯1 2和一外殼 14 〇 依據圖3 ’內杯〗2包括分別由紙板以習知方式形成的 一杯體22和一杯底24。在製造之前,以例如聚乙烯或類 • 似物的熱可密封塑膠材料塗覆在紙板上,然後已組合的杯 12在其內表面的全部或一部分,具有聚乙烯的內塗層15 〇 杯體22的截頭圓錐狀壁29在杯底24附近向內形成 一環狀肩部3 1,該肩部3〗做爲疊積杯子時供疊在上面之 另一子的阻擋之用。 杯底24以如圖所例示的方式設在杯體22。杯壁29下 緣的一段26向內且向上摺疊,以形成杯底24之環狀且向 # 下延伸的裙部2 8。 杯體22亦具有由其截頭圓錐狀側壁29向外形成5毫 米距離的環狀上肩部32,或由形成在杯體上緣之外捲邊 34更向下。在肩部32和捲邊34之間,具有環狀外表面 38的上壁段37(亦參見圖5),在肩部邊緣41設有表面 的下部3 9,其做爲結合(黏合)點1或結合(黏合)區2 。殻14之環狀內表面以下文所述的方式,結合(黏合) 於該結合點1或結合區2。 像杯壁29 —樣,外殼14呈截頭圓錐狀。外殼14是 -9 - 1277582 , (7) 由具有熱可密封塑膠材料內塗層42的紙板所形成。內塗 層可在全部或只在沿著外殻1 4之對應接觸路徑3 (亦參見 圖7 )的結合區或結合點。外殼1 4具有形成於其下緣的內 捲邊44(見圖3),且此內捲邊在杯12之下端上方大約 對應杯底2 4的高度處,卡合杯體壁2 9的外表面。 參見圖5,外殼14的環狀上邊緣9或51直接鄰接著 杯體22的捲邊34,且可大約在捲邊34的下方。外殼14 • 從那裡向下延伸至窄的環狀表面,該表面至少局部卡合上 壁段37和環狀外表面38,且在肩部32之下邊緣32的略 上方。 在杯1 2和殼14組合之前,在外殻14內側的熱可密 封塑膠塗層42局部地溶化。在殼14組合體於一以上結合 點或結合區1、2 (如圖6所例示的點熔接5 3 )進行熱結 合之後,殼體14在該點熔接53處結合於杯體肩部32或 結合於鄰接肩部下邊緣4 1的環狀外表面3 8,亦即距離捲 • 邊3 4約5毫米處。雖然此處描述爲以規律間隔沿著環使 用三個點熔接5 3,但是可少至一個或比三個還多的點熔接 53,且如果使用一個以上的點熔接53,則其間隔距離可不 相同。 也可能配置多個此種結合點或結合區在直立方向7的 彼此上方(參見圖3),或在水平方向6或圓周方向(參 見圖2 )並排。 現在參考圖4至圖8,容器10是依據下列步驟來製造 -10- 1277582 、 (8) *藉由環繞一截頭圓錐心軸,由紙板製成殼1 4,其係 選擇性地在內部塗覆例如聚乙烯熱可密封材料; *然後從心軸移除該殻,並將該殼安置在對應形狀的 接收器或接收構件20 (參見圖4 )內側。此接收構 件20包含一截頭圓錐裙部21(參見圖4),其緊 抵著殼壁1 6的外表面。在裙部2 1的上端,接收構 件20具有徑向向外延伸的上凸緣23。 • 在下一步驟中,環狀加熱元件抵在殻14的內側,且 聚乙烯塗層帶被加熱至其熔點(參見圖6)。 然後,藉由抽吸將先前組合好的杯1 2抽入殻內,直 到上肩部32的環狀周圍位抵在殼,且沿著對應接觸路徑3 的熔融帶(參見圖7)。 然後,環狀盤17做爲用於製造對應容器10之對應設 備1 1的第一構件,其被設在杯體22的內側,並緊貼地卡 合在杯體之上肩部32上方的內表面(參見例如圖6至8) •。 圓環1 8做爲對應設備1 1的第二構件,其具有三個可 徑向伸展的柱塞做爲按壓構件1 9。將該圓環1 8環繞殻1 4 且置於熔融帶的高度,並伸展該等柱塞以將殼和杯壁壓在 一起(參見例如圖6 ),直到他們分別在(例如)三個點 熔接53或結合點1或結合區2結合(黏合)在一起。此 種點熔接(s ρ 〇 t w e 1 d )在此稱爲點狀熔接(d 01 w e 1 d )( 參見圖7和8)。 然後移除盤和環,且已組合的容器被從接收構件20 -11 - (9) 1277582 排出。 依據圖6,上壁段37不需被殻壁16的上段段全部 觸’且該兩者在外捲邊34的下方可能存在一小間隙。 有沿著接觸路徑3 (參見圖7 ),藉由將第一構件1 7和 二構件18壓在一起(參見圖7)才可產生接觸。該接觸 徑3例如配置在鄰接對應於結合點或結合區的上環狀肩 32。 # 在圖8和圖7中,例示了具有柱塞19的環狀第二 件1 8,其配置在接收構件20之上凸緣23的上表面和外 邊的下端之間(參見圖6)。 在圖7中,也例示了做爲按壓構件1 9的對應柱塞 其沿著容器1 〇的圓周方向8平均地分布,且形成三個 合點或結合區。對應按壓構件在位移方向45可移動。 現在參考圖10至12,可看到例示本發明第二實施 特徵的容器1 〇在各種組合階段。除了一個特徵之外, • 器1 0的構造和先前所述的容器相同。容器的杯1 2和先 所述的杯相同,但是殼1 4具有形成在上端之較短圓筒 5 〇,該殼1 4的圓筒段5 0位抵上壁段3 7的外表面3 8且 者相平齊(也請參考先前的圖)。杯12和殼14在做爲 合點1或結合區2的一個以上的點5 3被點結合在一起 該點5 3對應於杯1 0中之結合點或結合區,亦即環繞著 即鄰接於其下邊緣41的肩部32。雖然圓筒段50在肩 3 2上方位抵杯1 2且齊平,但應瞭解圓筒段5 0並沒有結 於點結合5 3環上方的杯體’且藉由對應接觸路徑3的 接 只 第 路 部 構 捲 結 例 容 一、 刖 段 兩 結 立 部 合 無 -12- 1277582 , do) 結合部分’使對應的點結合或點熔接5 3彼此分離。 此外,第二實施例的接收構件2〇和第一實施例者不 同’因爲其具有一體成型第二構件18,該第二構件18形 成有反壓延伸部25 ’其從接收構件2〇的上凸緣23的上表 面直立地延伸。延伸部2 5的上端2 7從下面緊抵著捲邊3 4 〇 本發明的杯1 〇以下列步驟製造: Φ *藉由環繞具有上圓筒段的一截頭圓錐心軸,由紙板 製成殼,其係選擇性地在內部塗覆例如聚乙烯熱可 密封材料; *然後從心軸移除該殻1 4,並將該殼安置在對應形狀 的接收構件2 0 (參見圖1 〇 )內側; *在下一步驟中,環狀加熱元件抵在殼1 4的內側, 且聚乙烯塗層帶被加熱至其熔點溫度。 *然後,藉由抽吸將先前組合好的杯22抽入殼1 4內 • ,直到杯體之肩部3 1的環狀周圍位抵在殻的熔融 帶(參見圖11)。 *做爲第一構件17的圓環(參見圖12),其具有例 如三個可徑向伸展的柱塞做爲按壓構件1 9。將該圓 環1 8設在杯體22的內側位於熔融帶的高度,並伸 展該等柱塞以將殻和杯壁壓在一起,並抵住外部接 收構件20,特別是抵住對應的反壓延伸部25,直 到他們在例如三個點或點熔接53結合(黏合)在 一起(參見圖12)。 -13- 1277582 , (11) *然後移除環1 7,且容器1 0被從接收構件20排出。 前述的每一容器實施例,其特徵在於其殻1 4內側具 有熱可密封塑膠凸層,藉由在複數點熔接53 (其可爲結合 點1或結合區2)的熱或壓力,將該殼14結合於杯1 2的 外表面。對應的點熔接沿著這些組件之間延伸。這些點熔 接位於環狀路徑(見接觸路徑3 ),該環狀路徑鄰接於杯 體之上壁段37的下邊緣、或鄰接於殻14的上圓筒段50。 Φ 每一容器實施例也可藉由將熱可密封塑膠結合材料塗覆於 杯體外部的上壁段3 7而製成,此仍未脫離本發明。在此 一例子中,當然在將杯體插入殼內之前,就要從杯體外側 加熱結合材料。 【圖式簡單說明】 圖1是絕緣容器的側視圖,包含一內杯、一外殼、和 本發明第一型式的實施例; # 圖2是圖1之容器的下視圖; 圖3是圖1之谷益的側視圖’具有容器直立剖面的元 件; 圖4是經過圖1之容器的殻的頂部之放大直立剖面視 圖,顯示第一容器組合步驟; 圖5爲類似於圖4的視圖’顯示杯插入殼內; 圖6爲類似於圖4的視圖,顯示在進一步的容器組合 步驟中,殼和杯的點熔接; 圖7爲容器和用於點熔接的對應工具或設備的上視圖 -14 - (12) 1277582 圖8爲本發明容器組合圖7 以點熔接的工具之透視 圖; 圖9爲具體化本發明第一型式之絕緣容器類似於圖3 的視圖; 圖1 〇爲第二容器實施例類似於圖4的視圖,顯示第 一組合步驟; # 圖1 1類似於圖5的視圖,爲第二容器實施例在進一 步的組合步驟中;和 圖1 2類似於圖6的視圖,爲第二容器實施例在進一 步的組合步驟中。 【主要元件符號說明】 1 :結合點 2 :結合區 ® 3 :對應接觸路徑 4 :外表面 6 :水平方向 7 :直立方向 8 :圓周方向 10 :容器 11 :對應設備 1 2 :內杯 1 4 :外殻 -15- 1277582 、 (13) 1 5 :內塗層 1 6 :殼壁 1 7 ··第一構件(盤) 1 8 :第二構件(圓環) 1 9 :按壓構件 20 :接收器(接收構件) 21 :裙部 φ 22 :杯體 23 :上凸緣 24 :杯底 25 :反壓延伸部 26 :段 2 7 :上端 2 8 :裙部 2 9 :杯壁 # 3 1 :肩部 32 :(上)肩部 3 4 :外捲邊 3 7 :上壁段 3 8 :外表面 3 9 :下部 41:肩部邊緣(下邊緣) 42 :內塗層 44 :內捲邊 -16 (14) (14)1277582
