惟,熱可塑性樹脂薄片之中,例如有如聚乙烯醇系樹 脂薄片之融點與分解點非常的接近之薄片。此種薄片時如 果沒有精密的控制加熱溫度就會使該薄片分解之虞。所以 採用一般之熱密封法夾熔著薄片與薄片係非常困難。 又做爲可能精密的控制密封狀態之熔著方法而有脈衝 密封法,惟此種脈衝密封法乃因爲,將加熱體壓接於被密 封部,使被密封部熔融之後,待到被密封部之某一種程度 的冷却之後,從被密封部離開加熱體的實施熔著,因此熔 著所需之時間顯著的拉長,生產性低,同時會薄片發生熱 收縮,有損美觀之問題。因而做爲聚乙烯醇系樹脂薄片也 可以熔著之熔著手段,正在硏究開發,一種對於薄片也不 會有多餘之熱量之作用,使用融點與分解點非常接近之薄 片下,仍然能夠安定的且高速的實施熔著,顯著的可以提 高生產性之超音波密封之手段。 在此首先簡單的說明超音波密封。此種藉由超音波密 封之薄片與薄片之熔著係,利用超音波,引起局部的振盪 而令被著體發生摩擦發熱以資熔融接著者。 例如第1 3圖所示,超音波熔接機51係具備有:發生 超音波之超音波振盪子5 4、及出射由此超音波振盪子所 發生之超音波之喇叭5 2 ( horn )、及面向該喇叭所配置 之喇叭支架53,以及對於被熔著體壓接該出射超音波之 喇叭5 2之前端之接觸端部5 2 a用之壓力氣缸5 5。並且雖 不圖示,在於上述超音波熔接機5 1之喇叭5 2與喇叭支架 (3) 200400876 5 3之間,疊合仲置做爲被熔著體之層疊物品之二枚 ,藉由壓接喇叭先端之接觸端部5 2a,由而隨應於該 強度,由而藉來自超音波振盪子54之超音波而使被 體予以熔著或熔斷也。 當利用上述超音波密封之熔接機能,而從該較大 疊物品主體而有效率地細分(小分)一括地製出目的 小•形狀之複數之層疊物時,雖然藉熔著機能可以在 之任意處所之薄片與薄片之密封,惟不能做分斷,所 於薄片與薄片並列地空出間隔之二處所而予以密封( ),以切來切斷該二處所之封止部間由而施予分割。 惟使用此熔著手段時,如第1 4 ( A)圖及第14 ( 圖所示,由沿著層疊物品主體60之被熔著之密封部 65間,以虛線所示之切斷預定線60a而藉切刀61等 斷機實施切斷,所以在密封作業時封閉於密封部65 間之高滲透壓物質等之內容物64乃自切斷處所而漏 外方,由而污染附近、或降低作業效率,或浪費材料 且薄片62、63之切斷面66' 67都是維持被切斷時之 ,所以留存了由切斷所致銳利狀態之硬生生之情形。 必要的突出之端部係成爲被分離爲二片之不雅觀之形 於是由於利用超音波之熔斷機能時,可以做到一齊做 片與薄片之密封(封止)及切斷。由而可以考慮從較 薄片所成之層疊物品主體而有效率的一括製出被細分 分)爲目的之大小及形狀之層疊物品之手段。詳述之 此熔斷手段時,即如第1 5 ( A )圖及第1 5 ( B )圖所 薄片 壓接 熔著 之層 之大 面上 以將 封止 B ) 65 ' 之切 、6 5 出於 ,並 形態 而不 態。 到薄 大之 (小 ,在 示, (4) (4)200400876 在於層疊物品主體70中’藉由沿著圖中虛線所示之熔斷 預定線7 6 a而壓接超音波熔接機5 1之喇叭5 2之前端之接 觸端部5 2 a,由而以一次(同時)實施封止(密封)及熔 斷,所以不會有高滲透壓物質等之內容物74之在於熔斷 作業中從切斷處所而漏出於外部之情形’並且熔斷面76 係被施予一體化處理,成爲非常平滑、外觀良好之製品。 惟只用熔斷時,由於薄片7 2與薄片7 3之接合,密封很難 做到均等,所以在層疊物品之使用中有密封部發生破損之 虞。 【發明內容】 (發明之揭示) 本發明乃鑑於上述之情形所開發,其目的係提供一種 ,從較大之薄片所成之層疊物品中,有效率的一括地獲得 複數之被細分爲目的之大小及形狀之層疊物品時,可以確 實的接合密封薄片與薄片。又不會漏失內容物地可以分割 ,又該被分割之端面之被漂亮的一體化處理之被超音波密 封之層疊物品與其製造方法,及使用於它之超音波熔接機 〇 又,本發明之其他目的係提供一種,不會將內容物漏 洩於外部,確實的可以達成密封之層疊物品。 爲了達成上述目的,本發明乃著眼於超音波密封之熔 著及熔斷之二個機能,採至今未能達成之後述之構成來利 用而將該機能來達到,消失了在於二枚之薄片之間配存有 -9- (5) (5)200400876 滲透壓物質等之內容物之層疊物品主體之分割時之內容物 之漏失,同時解消了被分割後之各個之層疊物品之端部之 不雅觀之情形,更加上提高了各個之層疊物品之端部之封 止(密封)之確實性者。 詳述之,本發明之被超音波密封(封止)之層疊物品 乃,在於互相可能熔著之熱可塑性樹脂薄片之間’配存了 流動性物質之層疊物品中。該周圍邊緣部之至少一部係藉 由超音波熔著所致之接合部及形成於該外側之超音波熔斷 所致之接合部而多重地被密封地構成者’由而從雙重地予 以密封之周圍邊緣部係不會有亂洩漏於外部之情形,得將 此內容物確實地封閉於二枚之熱可塑性樹脂薄片之間’而 可以提高封閉(密封)之確實性。又,由於此多重之密封 而萬一由形成於內側之超音波熔著之密封部之一部份破損 時仍然得由形成於外側之藉由超音波熔斷所構成之密封部 而不致於將內容物漏洩於外側,可以達成確實地封入於內 部之情形。 同時萬一由形成於外側之藉由超音波熔斷所致之密封 部之一部份破損之情形時,仍然由形成於內側之超音波熔 著所致之密封部而可以將內容物之漏出抑制於最小限度也 。並且藉由超音波熔斷之密封部之端部係被形成爲漂亮平 滑地被施予一體化處理之情形’在於處理操作中沒有傷及 其他物品之虞同時可以提高層疊物品之端緣部之外觀也。 本發明之層疊物品乃’可適用於各種之內容物。特別 是保有了水等之流動性物質之袋之外’特別是做爲流動性 -10- (6) (6)200400876 物質而適用了高滲透壓物質、水溶性糊料、高分子吸收劑 、親水性醇、濕潤劑等等之脫水片等時很合宜。 本案中,所謂高滲透壓物質係,可舉例具有從欲脫水 之食品中吸收水份之滲透壓之物質而言。例如單糖類、二 糖類、多糖類、多價醇、低分子量有機羧酸、低分子量氨 基酸等等之含水物等等。特別是,麥芽糖、蔗糖、異性化 糖、葡萄糖、果糖、甘露糖醇、梨糖醇、麥芽糖醇、支鏈 澱粉等之食用糖類之含水物、或甘露聚糖、藻酸鈉、鹿角 菜膠、阿拉伯橡膠等之天然水溶性高分子、纖維素甲醚、 羧基纖維素甲醚鈉等之改質纖維素類。甘油、丙二醇等之 多價醇之含水物爲合宜。 又做爲水溶性糊料而指以分子量爲數千乃至數百萬程 度之具有長之鍊狀之分子構造之高分子化合物,且溶解於 水時呈顯增粘效果者而言。例如可以舉出:藻酸鈉、藻酸 丙二醇酯、甘露聚糖、澱粉、澱粉乙醇酸鈉、澱粉磷酸鹽 画旨鈉、鹿角菜膠、古柯膠、阿拉伯橡膠、亞黃著膠、刺槐 豆膠 '纖維素乙二酸鈉、甲基纖維素、羧基甲基纖維鈉等 之天然多糖類及其衍生體、谷膠、酪素、明膠等之蛋白質 。聚丙烯酸鈉、聚乙烯醇、聚乙烯基氧化物等之高分子化 合物。 做爲濕潤劑可以單獨或混合地使用,例如乙二醇、聚 乙二醇、丙二醇、聚丙二醇、二乙烯二醇單乙醚、1,3 -丁二醇、甘油、聚甘油等之多價醇、纖維素甲醚、羧基纖 維素甲醚鈉、木糖醇、山梨糖醇、多糖醇等等之吸濕性高 (7) (7)200400876 分子物質之水溶液等等。 又高分子吸收劑係含水後形成凝膠之物質,可以採用 施用於生理物品、紙尿布、土壤改良劑等等。例如,澱粉 、纖維素等之多糖類中添加,由水溶性或加水分解而可以 成爲水溶性之丙烯酸或其鹽,間丙烯酸或其鹽、丙烯酸酯 、間丙烯酸酯、丙烯酸醯胺、間丙烯酸醯胺、丙烯腈、間 丙烯腈、馬來酸、磺化苯乙烯、聚乙烯吡啶等等或這些之 齊聚物或共低聚合物之接枝聚合所得之由架橋劑而使親水 聚合體三次元地聚合者,或聚氧撑乙烯、聚氧撑丁烯、聚 乙烯吡、磺化苯乙烯、聚乙烯吡啶、聚丙烯酸鹽、丙烯酸 醯胺、聚間丙烯酸鹽、聚間丙烯酸醯胺等等之親水性聚合 物之藉架橋劑而聚合爲三次元者等等。 親水性醇乃指,在於常溫下液體,而具有與水之相溶 性之一價、二價或三價之醇而言。乙醇、丙二醇、甘油等 之食品之添加用之醇類最合宜。 又在於本發明中,熱可塑性樹脂薄片之至少其中之一 份(例如一面)係採用透水性薄片者爲合宜。由於使用了 透水性薄片而可以從透水性薄片側而對於層疊之薄片之間 通過水份。所以在於層疊物品之內部(二枚之薄片間)配 存了任意之流動性物質及水溶性糊料,而將其周圍邊緣部 予以密封做成薄片狀之層疊物品,由而可以做爲用於食肉 、鮮魚等之生鮮食品之接觸脫水之脫水薄片也。或在於層 疊物品之內部將高滲透壓物質及高分子吸收劑,以及親水 性醇一齊配存,將同樣可做爲用於食肉或鮮魚等之生鮮食 -12- (8) (8)200400876 品之接觸脫水之脫水薄片。再者,如果在於層疊物品之內 部再配存做爲濕潤劑之高滲透壓物質之一之親水性醇及高 分子吸收劑,即可以成爲兼倂兩者之性質之脫水及保水用 薄片也。 本例中之透水性薄片乃只要具備有,令水透過,且視 其必要塡充或挾持水之不會透過(漏出)高滲透壓物質等 之物質之性質即可以。可以例示由,聚乙烯醇、玻璃紙、 乙烯-乙酸乙烯共聚合體、皂化物、膠棉、聚醯胺等之半 透膜等等任一種薄片均可使用。惟考慮藉超音波熔接機所 實施之熔著或熔斷作業時,即採用聚乙烯醇系樹脂薄片爲 合宜。 本發明之被超音波密封(封止)之層疊物品之製造方 法乃,首先在於互相可以熔著之熱可塑性樹脂薄片之間配 存流動性物質。接著藉超音波來熔接該周圍邊緣部,同時 將該外側予以熔斷而予以密封(封止)者。如上所述地實 施熔著及熔斷,由而不致於洩漏配存於薄片間之流動性物 質等之內容物於外部也,有效率的連續製造出周圍邊緣部 之至少一處所地予以多重密封之各個之層疊物者。又,依 此超音波熔接機實施熔斷時,不致於將封閉於由二台超音 波熔接機之熔著所形成之二個密封部間之內容物洩漏於外 部地實施分割。 並且,熔斷之端部係成爲被施予漂亮平滑之一體化處 理之狀態,所以可以完全消除在於製程之處理中傷及其他 物品之虞,同時所分割出之各個層疊物品之端部之外觀係 (9) (9)200400876 呈顯雅觀之狀態也。 本發明之超音波熔接機乃,具備有··發生超音波之超 音波振盪子’及出射由此超音波振盪子所發生之超音波之 喇叭(喇叭),及面向於該喇叭地配置之喇叭支架,以及 對於喇叭及喇叭支架之其中之一或雙方,推壓於另一方之 推壓手段,而熔著用接觸端部及熔斷用接觸端部係形成於 上述喇叭及/或喇叭支架爲其特徵者。 本例中,可以分別備有形成了熔著用接觸端子之熔著 用喇叭,及形成有熔斷用接觸端部之熔斷用喇叭。 或具備:熔著用接觸端部與熔斷用接觸端部之形成於 一起之喇叭或喇叭支架也可以。 特別是分別具備有,面向於一個喇叭地予以配置之, 形成有熔著用接觸端部之複數之喇叭支架,及形成有熔斷 用接觸端部之喇叭支架就很合宜。 不管任一者,在於二個熔著用接觸端部之間,配置了 熔斷用接觸端部地構成者爲合宜。採此構成之結果,得以 配置於兩側之二個熔著用接觸端部實施熔著,同時以據於 其中間位置之熔斷用接觸端部而可以熔斷其中間,構成爲 能有效率的同時實施熔著作業及熔斷作業之機器也。 再者,將熔者用接觸端部配置於較熔斷用接觸端部之 前方爲合宜。 所謂「前方」係先壓接於層疊物品之意思’以製造生 產線之流線來說,據於上游之位置而言,同樣“後方”係指 同製造生產線之流線之據於下游之位置。採用此種構成之 -14 - (10) (10)200400876 結果,成爲熔著後才熔斷該鄰接之部份,更能防止配存於 二枚薄片之間之高滲透壓物質等之內容物之漏出於外部。 【實施方式】 (實施發明之最佳形態) 下面依附圖分別說明本發明之實施形態。 (層疊物品) 第1圖表示本發明之周圍邊緣部之被超音波密封之層 疊物品,第1(A)圖係表示其平面圖,及第1(B)圖係 縱斷面圖。 如第1圖所示,本實施形態之層疊物品1係,在於互 相可能熔著之二枚之熱可塑性樹脂薄片2、3之間,配存 由高滲透壓物質等所成之流動性物質4 ’而將該周圍邊緣 部由形成於內側之藉超音波熔著之接合部5以及由形成於 外側之藉超音波熔斷之接合部6來雙重地予以密封而成者 〇 再者,關於層疊物品之周圍邊緣部之雙重之密封(封 止)係第1圖所示之本實施形態之層疊物品係例示實施於 全周圍。惟本發明亦包括至少周圍邊緣部之一部份係雙重 地予以密封之層疊物品。 做爲可能熔著(熔融粘著)之二枚之熱可塑性樹脂薄 片2、3,即雖然由該目的之層疊物品之種類而不同,惟 如層疊物品係使用於食肉或鮮魚等之生鮮食品之接觸脫水 -15- (11) (11)200400876 之用之脫水片時,應使用可以使水透過,惟幾乎不透過實 施脫水作用之內容物之上述例示之透水性薄片群中所選用 者’例如考慮此後之周圍邊緣部之熔著等問題,而使用聚 乙烯醇系樹脂薄片即很合宜。又透水性薄片不必要使用表 背兩面同樣者,又也不必要兩面均使用透水性薄片。所以 至少一方係透水性薄片就可以。因此隨應於所欲之層疊物 而決定使用之透水性薄片爲一面或兩面,或適宜的設計採 用薄片之種類就可以。 再者,關於配存於上述薄片間之物質4也是隨應於目 的之層疊物品之種類而選擇使用。例如層疊物品係做爲脫 水片時,即由可以從欲脫水之食品等吸收水份之具有滲透 壓之由上述例示之高滲透壓物質群中所選用者。例如考慮 了操作性及容易獲得之問題,成本面來判斷,即使用蔗糖 就可以。 又做爲脫水片之物質並不侷限於上述,例如將由例示 之高滲透壓物質群之中所選擇者及由上述例示之水溶性糊 料群中所選擇者一齊配存,或由上述例示之高滲透壓物質 群之中所選擇者,及由上述例示之高分子吸收劑群中所選 擇者,以及由上述例示之親水性醇群中所選擇者配存在一 起亦可。 (超音波熔接機) 關於周圍邊緣部之密封,例如可以使用第2圖乃至第 4圖所示之超音波熔接機來實施。 -16- (12) (12)200400876 第2圖表示本發明之超音波熔接機之一例之槪略正面 圖。 第3圖係其槪略側面圖,第4圖表示其喇叭(超音波 喇叭)之槪略底面圖。 本超音波熔接機11係,具備有:發生超音波之超音 波振盪子1 4、及出射由此超音波振盪子1 4所發生之超音 波之喇叭1 2 (超音波喇叭)、及面向於此喇叭1 2地配置 之喇叭支架1 3。又此超音波振盪子1 4係亦備有,將出射 超音波之喇叭推壓於喇叭支架1 3,而將該前端壓接於被 熔接體之推壓手段之壓力氣缸1 5。 此超音波熔接機1 1係具備有,該前端形成有被尖銳 化之熔著用接觸端部1 2 a之二個熔著用喇叭1 2、1 2,以 及形成有由前端而尖銳化之熔斷用接觸端部12b之一個熔 斷用喇叭1 2。而形成了該熔著用接觸端部〗2a之二個熔 著用喇叭1 2、1 2係空著間隔地並列的予以設置,而形成 了熔斷用接觸端子1 2b之熔斷用喇叭1 2係據於該並列地 設置之二個之熔著用喇叭1 2之中間之位置地予以設置。 所以藉由隔著間隔並列地設置之二個之熔著用接觸端部 1 2a而並列地實施熔著,而以剩下之中間之熔斷用接觸端 部1 2b來熔斷該並列地熔著之處所之間。 又三個之喇叭1 2乃,將二個之熔著用喇叭1 2並列於 前方地予以設置,而剩下之熔斷用喇叭1 2係設置於二個 之熔著用喇叭1 2 ' 1 2之後方中間位置,由而以二個熔著 用喇叭1 2、1 2來實施熔著作業之後,藉熔斷用喇叭i 2來 (13) (13)200400876 溶斷該藉熔著用喇叭所熔著之其間,由而避免在於熔著作 業之θα被實施熔斷作業,防止配存於二枚之薄片間之高滲 透壓物質等之內容物之漏洩於內容物之外部。 在於超音波熔接中,能成爲熔著或熔斷乃由,對於被 熔接體之壓接力或接觸端部之形狀等所決定,通常熔斷用 接觸端部係較熔著用接觸端部更呈顯尖銳之形狀。 再者,做爲喇叭支架乃,只要接受來自喇叭之推壓力 而適當地將壓接力施加於被熔接體就可以,惟由於超音波 熔接機與被熔接體乃實施相對運動者,所以如第9圖乃至 第1 2圖所示之被軸支而旋轉自如之圓盤狀之喇叭支架1 9 (22、23、26、27)係更能順暢地實施熔著及熔斷所以很 合宜。 再者,第2圖乃至第4圖所示之超音波熔接機係具備 有二個熔著專用之喇叭及一個熔斷專用之喇叭者,惟並不 侷限於此構成,例如第9圖所示,於一個喇叭16之前端 形成二個熔接用接觸端部1 6a及一個熔斷用接觸端部1 6b 亦可以。再者也可以組合如第1 〇 ( A )圖所示之在前端形 成有二個熔著用接觸端部1 7a ' 1 7a之熔著用喇叭1 7,及 如第1 〇 ( B )圖所示之在於前端部形成熔斷用接觸端部 1 8a之熔斷用喇叭1 8也可以。又第9圖所示之例子係對 於形成於喇叭1 6之三個接觸端部1 6a、1 6b而以一個喇叭 支架19來對處者。 又,第1 〇圖所示之例子係,對於各接觸端部1 7a、 17a、18a而以複數之喇叭支架22、22、22來分別對處。 -18- (14) (14)200400876 再者,形成尖銳之形狀之接觸端部係不侷限於喇叭。 例如第1 1圖所示地,在於喇叭支架23上形成尖銳之形狀 之熔著用接觸端部24及熔斷用接觸端部25亦可以。此時 之喇叭2 8之前端形狀就可以採用平坦之形狀。 又第1 1圖所示之例子係在於一個喇叭支架23上,形 成有熔著用接觸端部24及熔斷用接觸端部25。惟不侷限 於此例’例如第1 2圖所示,分別以別體地形成該被形成 之熔著用接觸端部24之熔著用喇叭支架26,成有熔斷用 接觸端部25之熔斷用支架27,然後予以組裝也可以。此 時’亦可以如第1 1圖所示地,具備,對應於熔著用喇叭 支架2 6、2 6之一個喇叭2 8,及對應於熔斷用喇叭支架2 7 之喇叭29。 如上所述,雖然熔著或熔斷用之接觸端部係形成於喇 叭或喇叭支架之其中之任一方,惟形成於喇叭支架比較合 宜。按接觸端部係由於摩耗而長期間之使用後需要更換。 而喇叭支架係與喇叭比較而可以使用低廉之材料,所以可 以削減更換之費用。 再者,如壓力氣缸1 5等之推壓手段係將喇叭朝向錐 壓支架推壓或將喇叭支架朝向喇叭推壓,或互相推壓而對 於被熔接體有適當之壓力之施加就可以。所以如第2圖、 第3圖所示,設置於喇叭側,或如第9圖〜第12圖所示 ,設置於喇叭支架側,或設置於雙方也可以。 但是,推壓手段係設置於下方爲宜,如設於上方時, 即隨應於設於上方之物品(例如喇叭)之自壓而會發生壓 -19- (15) (15)200400876 力之影響。換言之,將推壓手段設置於下方時,更可以做 到適當,精確之推壓力之微調整。因而在於例如第9圖乃 至第1 2圖所示之例子中,由於喇叭支架係配置於下方, 所以推壓手段係設置於喇叭支架上變爲比較合宜。 又減少喇叭或喇叭支架之個數而可以企圖裝置整體之 小型化或降低成本。惟令設置推壓手段之喇叭或喇叭支架 之個別化,由而可以分別獨立地控制推壓力,成爲可能實 施微調整,可以實施適宜之熔著或熔斷也。 (層疊物品之製造方法) 第5圖表示,藉由如上構成之超音波熔接機11,而 從使用較大之薄片所製造之層疊物品主體中,獲得分割成 爲所欲之大小及形狀之被細分(小分)之層疊物品之情形 〇 第5 ( A )圖係說明使用較大之薄片所製造之層疊物 品主體之被細分之分割處所之平面圖,第5 ( B )圖係表 示其細分分割狀態之一部份放大之槪略斷面圖。再者在於 下述之說明中,圖中之符號係使用與前述之符號相同之符 號,而省略必要以外之說明。 如第5圖所示,使用較大的薄片所製造之層疊物品主 體10之周圍邊緣部乃預先藉由任意之手段而被密封(封 止)。該密封部7係只要使二個薄片互相接合就可以,所 以使用任何手段所形成者均可以。所以使用通常之超音波 熔著所形成者,或以熱密封來形成者等等如果能夠確實的 -20- (16) (16)200400876 將周圍邊緣部密封者時就可以。 於是層疊物品1 0之細分分割係,在於該面上隔著設 定爲獲得所欲之大小及形狀之間隔地二條並列地予以設置 之半格子狀之二重虛線之各熔著預定線5 a,及沿著此二 條之熔著預定線5 a、5 a間以虛線所示之熔斷預定線6 a地 ,一面將超音波熔接機1 1之各喇叭之前端之接觸端部 12a、12a、12b壓接於層疊物品主體1〇地移動來實施者 。換言之,沿著二條之熔著預定線5 a、5 a地一面壓接超 音波熔接機1 1之各熔著用喇叭之接觸端部1 2 a ' 1 2 a地予 以移動,同時沿著於此二條之熔著預定線5 a、5 a間以虛 線所示之熔斷預定線6a而一面壓接超音波熔接機1 1之熔 斷用喇叭之接觸端部12b予以移動,由而實施熔著及熔斷 也。 由而可以複數地形成,該由周圍邊緣部之二處之,由 形成於內側之由超音波熔著之接合部5,及形成於外側之 由超音波熔斷之接合部6而雙重地被密封之I型式之層疊 物品。以及周圍邊緣部之三處所之同樣地被雙重密封之II 型式之層疊物品也。又,此時,該由二條之熔著預定線 5a、5a之被熔著,由而被封閉在該間之高滲透壓物質4a 乃繼續地被封閉於雙重地被密封之由熔著之接合部5與由 熔斷之接合部6之間而在被分割時沒有漏出於外部之情形 ,並且該被分割之斷面也帶圓弧狀地平滑地施予一體化處 理,所以該端部之外觀上漂亮雅觀,在處理中也不會有傷 及其他物品之虞。 -21 - (17) (17)200400876 接著說明,連續獲得至少周圍邊緣部之一部份之被雙 重密封之層疊物品時之第1實施形態。 第6 ( A )圖係說明使連續之規定寬度之薄片製造時 之第1形態之槪略平面圖。第6 ( B )圖係表示被細分( 小分)分割之層疊物品之層疊物品之放大圖。如第6圖所 示,具有規定寬度之可能互相熔著之二枚之熱可塑性樹脂 薄片之間,配存高滲透壓物質等之物質,且具有預先其兩 側緣係由任意之手段所接合之密封部7之連續層疊物品 20,連續地推送於流線(生產線)。接著在層疊物品20 之被移送到可以做成規定之大小之處所,使具有二個熔著 用接觸端部12a、12a及具有一個熔斷用接觸端部12b之 超音波熔接機1 1,朝向連續層疊物品20之面上之與兩側 邊緣部密封部交叉之方向地將各喇叭之接觸端面一面壓接 於連續層疊物品20,一面予以移動。 於是周圍邊緣部之二處所,換言之,該與兩側緣部密 封部交叉之方向之面向之周圍邊緣部乃,由形成於內側之 超音波熔著所致之接合部5,及形成於外側之由超音波熔 斷所致之接合部6而被雙重地被密封(封止)。效率良好 地連續的可以製造出被分割爲所欲之規定大小之層疊物品 。此時,當然被封閉於二條之熔著接合部5、5間之高滲 透壓物質不會漏出於外部,且可以分割成爲任意之大小及 形狀。並且分割之斷面也被去角(圓弧狀),且平順地施 予一體化處理,其端部係外觀雅觀,處理作業中也不會傷 及其他物品。 -22- (18) (18)200400876 接著說明,連續製造至少周圍邊緣部之一部份之被雙 重密封之層疊物品時之第二光實施形態。 第7(A)圖係說明製造連續之大寬度之薄片來製造 之狀態之槪略平面圖,第7 ( B )圖係表示被細分(小分 )分割之層疊物品之放大圖。如第7圖所示,在於較規定 者之寬度很寬之互相可能熔著之二枚之熱可塑性樹脂薄片 之間配存高滲透壓物質等之物質且預先以任意之手段密封 了其兩側緣部狀之連續層疊物品3 0連續的流送於超音波 熔接機上。(生產線上)。 接著,藉熔著用超音波熔接機21、21而一面密封其 兩側緣部,一面以能成爲所欲之寬度地對於連續層疊物品 3 0之面上之中間部,將具有二個熔著用接觸端部1 2a、 1 2a及—個熔斷用接觸端部丨2b之超音波熔接機n,以各 喇卩八之接觸端部壓接於連續層疊物品3 〇上,一面移動於 與兩側緣部之密封部之同一方向,由而在於側緣部之其中 t 一方向地形成,由形成於內側之超音波熔著之接合部5 ’及由形成於外側之由超音波熔斷所成之接合部6而雙重 密封(封止)之側緣部,於是可以高效率地連續製造被分 割爲規定之(所欲之)寬度之連續層疊物品3 0a。 並且,將該被分割爲規定之寬度之連續層疊物品30a 之被推進了可成爲所欲之大小之處所之時點,而令具有二 個溶著用接觸端部12a、12a及具有一個熔斷用接觸端部 1 2b之超音波熔接機1 1,以各喇叭之接觸端部朝向與被分 割爲規定之寬度之連續層疊物品3 0a之面上之兩側緣密封 -23- (19) (19)200400876 部成交叉之方向一面壓接於連續層疊物品3 0 a,一面予以 移動。由而周圍邊緣部之三處所’即與兩側緣密封部成交 叉之方向之二個周圍邊緣部’及與兩側緣部密封部同一方 向之周緣部乃,由形成於內側之藉超音波熔著之接合部5 及由形成於外側之藉超音波熔斷之接合部6而雙重地被密 封,於是高效率地以每次二列地連續製造被分割爲所欲之 大小之層疊物品。當然,此時也不會將封閉於二條之熔著 接合部5、5間之高滲透壓物質等洩漏於外部地可以分割 成任意之大小形狀。並且被分割之斷面也被施予圓滑之一 體化處理,該端部係外觀雅觀,在處理作業中也不致意傷 及其他物品之虞。 下面接著說明連續地製造至少周圍邊緣部之一部份之 被雙重密封(封止)之層疊物品之第三實施形態。 第8A圖係說明,使用連續之三倍寬度之薄片所製造 之狀態之槪略平面圖。第8B圖係表示被細分(小分)之 層疊物品之放大圖。 如第8A、8B圖所示在於具有規定寬度之三倍寬之互 相可以熔著之二枚之熱可塑性樹脂薄片之間,配存高滲透 壓物質等之物質’而預先以任意之手段來密封其兩側緣部 狀態之連續層疊物品40,連續地流送(推進)於超音波 熔接機所構成之生產線。接著,藉熔著用超音波熔接機 2 1、2 1 —面密封其兩側緣部,在將成爲所欲之寬度地三 等分連續層疊物40之該面上之二處所上,將有二個熔著 用接觸端部12a、12a及具有一個熔斷用接觸端部12b之 -24 - (20) (20)200400876 超音波熔接機1 1之各喇叭之接觸端部,以與兩側緣密封 部之相同方向地一面壓接於連續層疊物品3 0上一面予以 移動,由而在於側緣部之任何一方或兩方地形成:由形成 於內側之藉超音波熔著之接合部5,及形成外側之藉超音 波熔斷之接合部6而雙重地密封之側緣部,於是可以高效 率地連續地形成被分割爲規定(所欲)之寬度之二種連續 層疊物品40a及40b也。 並且該被分割成爲規定之寬度之二種之連續層疊物品 40a及40b之被推進至可成爲規定(所欲)之大小之處所 時點,令具有二個熔著用接觸端部12a、12a及具有一個 熔斷用接觸端部1 2b之超音波熔接機1 1,以與被分割成 所欲之寬度之二種之連續層疊物品40a及40b之面上之兩 側緣密封部交叉之方向地,將各喇叭之接觸端部一面壓接 於二種之連續層叠物品40a及40b,一面予以移動,於是 周圍邊緣部之三處所,即與兩側緣部密封部成交叉之方向 之二個周圍邊緣部成交叉方向之面向之二個周圍邊緣部, 以及與兩側緣部密封部相同之一個周圍邊緣部以及周圍邊 緣部之四處所,換言之,所有之周圍邊緣部乃由,形成內 側之藉超音波熔著之接合部5,及形成於外側之藉超音波 熔斷之接合部6而雙重地被密封(封止)。由而高效率地 可以連續製造被分割爲所欲之大小之層疊物品,當然此時 亦是不會將被封閉於二條熔著接合部5、5間之高滲透壓 物質等漏洩於外部地可以分割成爲任意之大小及形狀。並 且被分割之斷面亦被施予圓滑之一體化處理,因此該端部 -25- (21) (21)200400876 係外觀雅觀,且在處理作業中也沒有傷及其他物品之虞。 再者,本發明乃不侷限於依附圖所說明之上述實施形 態’在不逸脫本發明之要旨之範圍當然仍然可以做任意之 設計變更等等。例如,採用使超音波熔接機在於層疊物品 主體之面上,可以自由移動由而實施熔著及熔斷之構成。 由而可以減少超音波熔接機之台數也。 (產業上之利用可能性) 如上所述,依本發明時,可以從較大之薄片所成之層 疊物主體而,不會使內容物漏出於外部也,有效率地複數 一括地製造出被細分(小分)爲目的之大小及形狀之層疊 物品。 又被分割之端面係被施予圓滑一體化處理,所以其端 面之外觀雅觀,又可以消除在於處理作業中傷及其他物品 之虞。 又萬一由於薄片之周圍邊緣部之由熔著或熔斷之密封 不完全之情形下’由於周圍邊緣部係經過再熔著或熔斷而 被多重地密封,因此不致於將內容物漏出於外部地確實的 予以封閉於其內部也。 【圖式簡單說明】
