201125789 六、發明說明： 【發明所屬之技術領域】 本發明係有關在設有喷出口之喷霧罐内裝填有液化氣及保 液用吸收體之喷霧罐製品，尤指一種適用於罐中充填有除塵闬噴 霧劑之塵埃吹喷器，及裝填有可燃氣體之火焰喷燈用氣罐等之喷 霧罐製品，以及其製造方法。 【先前技掏·】 使用喷霧罐之製品，例如’塵埃吹噴器（除塵吹散器），係在 具有喷射按鈕或扳機之金屬製喷霧罐内封填有壓縮氣體或液化 氣等之喷霧劑之罐體’而藉由按下噴射按鈕或扣下扳機喷出氣 體，以吹除附著於各種機器類上之塵埃。包含此種塵埃吹喷器之 喷霧罐製品之喷霧劑，以往多採用I利昂氣體(Freon gas)，因其 係臭氧層破壞物質，近來其使用規定極為嚴格。為此，業者多轉 求臭氧層破壞係數更低之喷霧劑進行開發，現在已有所謂之替代 氟利昂’如：HFC134a(CH2F-CF3)、HFC152a(CH3-CHF2)等被普 遍使用。 然而’ HFC134a因係不燃性氣體而具有無燃燒起火之危險 之優點，但其地球暖化係數高達1300。至於HFC152a(CH3-CHF2) 之地球暖化係數只有140，但為可燃性氣體，在使用上須特別謹 慎》又，此等替代氣利昂價格高昂，且為氟化物，具有如接觸到 火便會產生劇毒之氟酸之性質，因此，在使用上之安全性有相當 大之問題存在。 一方面，近年來，對地球環境保護之關心高漲，不僅僅是對 臭氧層之破壞，就是氣縣分排放大氡所造成之環境污染，特別 201125789 二’對1球暖化之影響不容忽視。綠色採購法由政府等促進採購 衣境物之法律）中將隨著使用排出之溫室效果氣體等對周遭 裒境之負之物品定為「環境物品」，而吹塵器（塵埃吹喷器） 亦順應此潮流，其「判斷基準」自平成20年（西元2_年Μ月 1日起修改為「不使用破壞臭氧層之物f及氫氟破化合物（即所 謂替代氟利昂）」。 由於此修法，使用替代氟利昂之製品已不再被列為可標示綠 色採構法董子象物品之「環境物品」，另外作為能滿足修正後之「判 斷基準」之喷霧劑，無臭氧層破壞之問題且地球暖化係數極小之 -曱醚(DME)最受注目。但二甲喊為可燃性氣體，使用時或保管 時在安全性上有問題。 又，利用火焰（火炬）之各種作業所使用之喷火燈用之氣罐， 通常，係於具有噴出部之喷霧罐狀之金屬製耐壓容器，裝設内部 充填有可燃氣或液化燃料氣等燃料之卡式氣體罐所構成，而將燃 料引入安裝在喷出部之噴火頭燃燒喷火者。噴火燈用之燃料大都 使用上述二甲醚或具咼熱量而燃燒排氣中含有之二氧化碳(c〇2) 量比石油或煤炭少之無臭氧層破瓌之問題之液化石油氡⑺。 喷火燈用之氣罐，亦具有與塵埃吹喷器同樣之構成，因使用 可燃性氣體，而對安全上之要求與考量尤為重要。特別是，使用 液化氣體之喷霧罐製品，通常，在喷霧罐内裝填用古廢紙等粉碎 之纖維做為吸收體，但是，如果以顛倒狀態或傾斜狀態使用時， 液化氣如以液態原狀自喷出口漏出時，有引火之虞。、 針對此問題，本發明人等曾在專利文獻丨中，提案使用二甲 醚配合碳酸氣做為其他配合成分，以賦與塵埃吹喷器中之喷霧劑 201125789 以難燃性。二曱醚雖為可燃性，但其臭氧層破壞係數及地球暖化 係數皆極小，而與碳酸氣混合後可提高安全性。（專利文獻1 : 特開2005-206723號公報） 又，本發明人等在專利文獻2中，提案喷霧罐用之吸收體係 以將木材紙漿粉碎所得之纖維素纖維集料構成，此吸收體含有纖 維長0.35mm以下之微細纖維素纖維在所定量以上。由於此種吸 收體含有將纖維素纖維以機械或化學手段粉碎之微小纖維，具有 優異之吸收性能及保液性。（專利文獻2 :特開2008-180377號公 報） 其他種吸收體有如專利文獻3〜專利文獻5所記載之多孔性 發泡合成樹脂，為眾所知，例如，專利文獻3、4中係使用聚烏 拉坦樹脂（聚胺基曱酸酯樹脂）泡沫體，其形成係將原料樹脂注入 罐内使之發泡而成，省免了裝填工程。又，專利文獻5係使用酚 樹脂之發泡體，而將酚樹脂發泡體依罐體形狀成型之後，壓入罐 内。（專利文獻3 :特許第2824242號公報，專利文獻4 :特開平 10-89598號公報，專利文獻5 :特開平9-4797號公報） 【發明内容】 按專利文獻1之方法，無法適用於火焰喷燈（喷火燈）用之氣 罐，而即使應用於塵埃吹噴器之喷霧劑時，欲僅僅添加碳酸氣以 賦與難燃性，必須提高碳酸氣之重量比，則喷霧罐所要求之耐壓 強度需要提高，喷霧罐之製造成本因此隨之增加。塵埃吹喷器常 以傾斜狀態或顛倒狀態使用，而為有效吹走塵埃、粉塵等更常有 連續吹喷之傾向。因此，如使用之碳酸氣之重量比率小時，欲保 持完全氣化之狀態來達成連續喷射即變成相當困難。又，若將碳 201125789 酸氣對二甲醚以高重量比率混合，則欲於喷霧罐内保持均勻之混 合狀態，並非容易，使用時，碳酸氣反而會先逃逸而難保製品之 品質安定，有減損使用感之虞。 專利文獻2之吸收體，因含有大量微粉狀之細微纖維素纖 維，於原料紙漿之解纖、粉碎之過程中容易含入空氣，處理上不 容易。因此，依習知之方法，欲將必要重量之吸收體裝填於喷霧 罐内頗困難，實際上，大多採用濕式法將微細化之纖維堆置於板 片上後，依罐體形狀捲起成一捲裝填於罐内；或將微細化之纖維 添加以黏合劑使纖維與纖維間結合為一體之後，予以成型之方 法，製造工程則變得相當複雜。又，添加黏合劑，成本即增高， 同時，黏合劑如成膜狀覆於纖維表面時，吸收性能便降低，以上 均為其缺點。也有將使用集塵器捕集到之徼細纖維予以堆積後裝 入不織布等製成之袋中之方法，唯裝袋及封口作業費時，作業性 及生產性難說良好。 由專利文獻3〜5之多孔性發泡合成樹脂所形成之吸收體， 不僅在發泡成型時需等時間，而且原料樹脂亦昂貴，成品偏高。 又，多孔性發泡合成樹脂雖具優良之保液性能，但殘留氣體容易 滯留於喷霧罐内，很難全部用完到最後，亦為其問題。 有鑑於上述諸問題，本發明之目的在提供一種喷霧罐製品， 在製品呈傾斜狀態或顛倒狀態使用或保管時，能防止漏液發生， 且即使使用可燃性液化氣，亦能確保其安全性及保液性，同時， 不必使用昂貴之原料或複雜之製造工程，因而能減低成本，並能 提高良好之作業性、生產性及經濟性；本發明之目的亦提供製造 該喷霧罐製品之方法。 201125789 為解決前述課題，本發明所提供之解決方案具有下列構成。 即： 本申請案之請求項1之發明，係一種於具備喷出口之喷霧罐 内裝填有液化氣及保液用吸收體之喷霧罐製品； 其特徵在於：上述吸收體係由含有纖維長1.5mm以下之纖 維素纖維90質量％以上之纖維素纖維集料所構成，而上述噴霧 罐内部位於上述喷出口側留有一空間部，其下方則收容有經壓縮 成形為與噴霧罐胴體部對應形狀之塊狀之上述吸收體，且於上述 空間部與上述吸收體之間設置有具通氣性可保護上述吸收體表 面之蓋狀構件。 依本發明，壓縮成型為塊狀吸收體及其上面之蓋狀構件能防 止喷霧罐在傾斜狀態或顛倒狀態使用或保管時發生漏液。此時， 直接裝填於喷霧罐内之吸收體之上面因由蓋狀構件密封，故在裝 填液化氣或喷霧使用時，微粉狀之微細纖維素纖維不會飛散，即 使使用可燃性之液化氣亦可確保安全性及保液性。又，因無需使 用價格昂貴之原料或造成製造工程複雜化，而可減低成本，同時 能提供作業性、生產性、經濟性皆優之喷霧罐製品。 依請求項2之發明，上述蓋狀構件係經壓入上述喷霧罐内而 密接上述吸收體之表面之圓盤狀多孔質體。 上述蓋狀構件因在喷霧罐内密接定位於吸收體上面，以使吸 收體與上面空間部隔離密封，並制止吸收體之位移而確保該空間 部之同時，也能有效防止微細纖維素纖維飛散。 依請求項3之發明，上述蓋狀構件係一體形成於上述吸收體 之表面之多孔質保護層。 201125789 由於將上述蓋狀構件與吸收體一體形成，因此可保持吸收體 之形狀確實達成密封，而確保喷霧罐内之空間，並可有效防止微 細纖維素纖維飛散。 依請求項4之發明，上述蓋狀構件之上述圓盤狀多孔體或上 述多孔質保護層係由不織布或發泡性樹脂所構成。 上述蓋狀構件由於使用多孔質具有通氣性之材料之發泡性 樹脂或不織布構成，選用材料較自由。 依請求項5之發明，上述吸收體係預先將上述纖維素纖維集 料壓縮成型為對應於喷霧罐形狀之圓柱形塊狀成型體之後，直接 裝填於上述喷霧罐内者。 由於可將纖維素纖維集料事先加工成為罐形壓縮成型體，因 此容易接裝填於罐内，而使製造工程簡化。 依請求項6之發明，上述液化氣係可燃性液化氣。 本發明使用於内部裝填可燃性氣體之喷霧罐製品特別有 效，不僅可防止漏液，而且大幅提高安全性。 依請求項7之發明，上述液化氣係臭氧層破壞係數為零，且 不含氫氟碳化物之氣體所構成。 由於液化氣係使用格外不破壞臭氧層且不含氫氟碳化物之 氣體，因此對環境之影響可減至最小。 依請求項8之發明，上述吸收體係由含有纖維長0.35mm以 下之微細纖維素纖維45質量％以上之纖維素纖維集料所構成。 構成吸收體之纖維素纖維集料，如含有纖維長更短之纖維素 纖維在所定量以上時，其保液性更佳。 依請求項9之發明，係一種製造具有喷出口且内部裝填有液 201125789 化氣及保液用吸收體之喷霧罐製品之方法，包括下列各工程： 將原料纖維藉機械粉碎使成為含有纖維長l.5mm以下之纖 維素纖維9 0質量％以上之纖維素纖維集料之工程； 將該纖維素纖維集料按所定量計量之後，向喷霧罐之徑向予 以壓縮，使大致形成與喷霧罐形狀相當之形狀，而成為做為吸收 體之塊狀壓縮成型體之工程；及 將該吸收體自噴霧罐之上部開口壓入罐内之後，將圓盤狀多 孔質體壓入上述喷霧罐内部使之緊密疊置於上述吸收體之上 .面，或者在上述吸收體之上面將多孔質保護層一體形成以做為蓋 狀構件’並於此蓋狀構件之上部形成一空間部之工程。 根據上述製造方法，即使吸收體含有大量之微粉狀微細纖維 素纖維之情形時，因預先將吸收體徑向壓縮成為與罐體同形狀之 塊狀壓縮體之後裝填於罐内，其次配置蓋狀構件即可，因此，可 以簡易之製造工程有效率的製造喷霧罐内已直接裝填有吸收體 之製品。此時，吸收體因經事先向喷霧罐之徑向壓縮之故，直接 裝填之吸收體在喷霧罐内保持密度均勻，而可提高保液性能，且 在吸收體上再用蓋狀構件密封，更可防止吸收體之細微纖維飛 散’於是可製得高品質之喷霧罐製品。 依請求項10之發明，係一種製造具有喷出口且内部裝填有 液化氣及保液用吸收體之喷霧罐製品之方法，包括下列各工程： 將原料纖維藉機械粉碎使成為含有纖維長1.5πΗη以下之纖維素 纖維90質量％以上之纖維素纖維集料之工程；將該纖維素纖維 集料按所定量計量之後，向喷霧罐之徑向予以壓縮，使大致形成 與喷霧罐形狀相當之形狀，而成為做為吸收體之塊狀壓縮成型體 201125789 之工程；及將圓盤狀多孔質體所形成之蓋狀構件 喷霧罐之底部開口壓入罐内之後，再將上述吸收體壓入上述 底部開口内’使之緊密接著於上述蓋狀構件，並於此蓋狀構件之 上部形成一空間部之工程。 根據上述方法’同樣是預先將吸收體徑向壓縮成形為與罐體 同形狀之塊狀壓縮體之後，再裝填於罐内已先配置好蓋狀構件之 罐内’因此’可以簡易之製造工程有效率的製造喷霧罐内已直接 裝填有吸收體之製品。又，吸收體因經事先向喷霧罐之徑向壓縮 之故’裝入後吸收體在噴霧罐内保持密度均勻’而可提高保液性 月b ’且在吸收體上再用蓋狀構件密封，遂可防止吸收體之細微纖 維飛散，於是可製得高品質之喷霧罐製品。 【實施方式】 以下’將本發明之喷霧罐製品及其製造方法基於具體實施形 態詳細說明。 本發明之喷霧罐製品，只要是具有喷出口之喷霧罐中裝填有 液化氣及保液用吸收體之喷霧罐製品均可適用。具體例為，如除 塵用之吹喷器（塵埃吹噴器）或火焰噴燈（喷火燈）用氣罐等均是。 做為一典型之代表例，在此就使用於除塵用吹喷器之情形參 閱附圖具體說明之。第1圖（a)表示塵埃吹喷器之整體構成之概 略圖，顯示喷霧罐1之頭部固定有具備一喷射扳機比之喷射部 la之構造。第1圖（b)、（c)顯示喷霧罐1之内部收容有吸收體2， 液化氣之喷霧劑3藉吸收體2吸收保存者。金屬製喷霧罐丨具有 疋直徑之胴體部及向下擴徑之錐台狀頭部，而在頭部頂面中央 设有喷出口 11。此喷出口 u係構成可藉扣壓喷射扳機lb而啟 10 201125789 開閥以噴出氣體之構造。 吸收體2係經壓縮成型為大略與喷霧罐丨之内徑同徑之圓柱 塊狀體，向度比喷霧罐1之等徑胴體部略矮，而以上方之頭部側 留有空間部12之狀態收容於喷霧罐丨内。做為喷霧劑之液化氣 3係以由構成吸收體2之經粉碎之纖維素纖維與纖維間之間隙吸 收保持之狀態收容於噴霧罐1内，當扣喷射扳機比使噴出口 U 開放時，喷霧氣即可由喷嘴lc喷出而將塵埃吹走除去。喷霧罐 1之胴體部近上端處，設有蓋狀構件4以將空間部12與吸收體2 隔開。吸收體2並未由任何做為表皮之膜片或袋子等包覆，直接 充填於喷霧罐1内，蓋狀構件4係密貼於壓縮成型之吸收體2 之上表面，而將此表面覆蓋著。如此之構成，蓋狀構件4乃可保 。蒦吸收體2之表面並使其能通氣，同時，制止吸收體2移位而防 止其表面之微細纖維素纖維飛散。 - 本發明中，吸收體2係由含有纖維長1.5mm以下之纖維素 纖維90質量％以上之纖維素纖維集料構成。纖維素纖維之纖維 長定為1.5mm以下，並將其加壓壓縮成為纖維集料裝填於喷霧 罐1内予以封閉，而變成可吸收儲存所要量之液化氣，且可提高 保液力及改善安全性。較佳者，纖維素纖維集料以含有纖維長 1.0mm以下之纖維素纖維80質量％以上者更具效果。尤其是， 含有纖维素0.35mm以下之微細纖維素纖維45質量％以上時，貝ij 更可提高液化氣之吸收性能及保持力，而對於噴霧罐1傾斜或顛 倒狀態使用時或保管時’能十分有效的防止漏液發生，故更佳。 在此’本發明中所謂之「纖維長」係指用纖維長測定機 FS-200(卡亞尼公司製造）測定之平均纖維長。 11 201125789 吸收體2係將含有纖維素纖維之原料解纖、粉碎、微細化所 得纖維長〇.35mm以下之微細纖維素纖維為主體之吸收體。纖維 素纖維之粉碎可利用機械式或化學式手段（裝置）、或此兩者之手 段實施。較適合之手段為採用機械手段予以粉碎、分級之方法， 藉此便可以簡單之工程獲得含有所要之纖維長之微細纖維素纖 維在所定含量之細纖維素纖維集料。 可做為吸收體2之原料之纖維素纖維，有諸如：針業樹、闊 葉樹之經漂白或未經漂白之化學紙漿、溶解紙漿、廢紙紙漿、甚 至棉花等任意之纖維素纖維。將上述各種纖維素纖維原料選用幾 種適當混合來使用，當然亦可行。將這些原料加以粉碎處理成為 所需纖維長，即可適用於本發明之吸收體。針業樹漂白牛皮紙漿 (NBKP)、闊葉樹漂白牛皮紙漿（LBKP)因具有良好吸收性、保液 性及不會引起液化氣著色之特點優異，而非常適用。 廢紙紙漿具有成本低及對環境之負担小之利點。廢紙紙漿本 來具有纖維之保液性稍差，且纖維附著有印刷油墨等問題存在， 然而，只要如本發明，大量使用經粉碎成纖維長1.5mm以下， 較佳為1.0mm下之纖維素纖維為主體，特別是使用纖維長 0.35mm以下之微細纖維素纖維，並加以壓縮成型後直接裝填於 喷霧罐1内所構成之吸收體2時，便可達到十分良好之保液性之 效果，已獲得證實。經推測分析，蓋因將吸收體2直接裝入喷霧 罐1後，微細纖維素纖維在喷霧罐1内向四周均勻擴開，而能將 液化氣均勻保存於吸收體2整體内部，遂可提高保液性能之故。 廢紙紙漿如過於損傷、老舊，可藉增加纖維長0.35mm以下之微 細纖維素纖維之含有量或裝填量，抑或不單獨使用而與他種原料 12 201125789 紙漿混合使用，以調製成可得所期之保液性為宜。 做為原料之纖維素纖維之機械粉碎方法，主要是使用旋轉型 磨碎機或喷磨機等高速衝擊粉碎法、軋碎機粉碎法等。在前段工 程亦可先用撕散機等之剪斷破碎法加以粗粉碎。又，製造其他纖 維製品時所得之纖維副產物（下腳）同樣可使用。例如，在製造紙 漿吹喷積層不織布時，自袋濾器中回收之纖維素纖維含有大量微 細纖維素纖維，因此，可將此直接做為原料或與其他纖維素纖維 混合做為所要之纖維素纖維集料來使用。如此，可簡化製造工程 而頗方便。 所使用之粉碎機之處理條件，可視所要求之微細纖維素纖維 之物理性質而適當選擇；又，其處理方法，可採批次式或連續式 之任何一方式進行；若將數台裝置串連成一列，在第一階先進行 粗處理，而在最後階段方進行微細處理亦可行。 又，將預先使用機械式裝置粉碎之纖維素纖維加以選別分 級，使之含有纖維長1.5mm以下之纖維素纖維90質量％以上， 或較佳為纖維長1.0mm以下之纖維素纖維80質量％以上，更佳 為纖維長〇.35mm以下之微細纖維素纖維45質量％以上，亦屬可 行。或者，分級後再與其他任意之纖維素纖維混合，將具有纖維 長為1.5mm以下，較佳者為纖維長1.0mm以下之纖維素纖維調 整，或者將具有纖維長為〇.35mm以下之微細纖維素纖維調整， 使其含量達到所希望之量者也合用。 又，纖維長因係有機物質而具柔軟性，僅依賴機械式粉碎處 理如難獲得微小之纖維素粒子之狀況時，為了獲得微細纖維素纖 維，也可採用化學處理與機械處理組合之方法來處理。通常，纖 13 201125789 維素係由結晶領域與非結晶領域所構成，非結 反應，因此，採用化學處理，例如與礦酸反應以溶解出非=領 域二而獲得結晶部主體之纖維素纖維之方法，已為眾所周知曰，曰將 所侍之結晶部主體之纖維素纖維進一步用機械再 微細之纖維素粒子。 文·1件 再者’利时㈣拌式之濕式料機進行粉碎處理亦可行。 介質搜拌式之濕式粉碎裝置係插裝於固定式粉碎容器之搜掉機 南速旋轉’以將裝人粉碎容器内之介質與纖維素纖維麟以產生 f斷應力，而予以粉碎之裝置，有塔式、槽式、流通管式、曼祕 拉式等’但是’只要是介質㈣方式，無論採用何種裝置均^。 其中以使用砂磨機、超黏磨機、紙聚精磨機、金剛石精磨機甚佳。 將紙衆❹上述粉碎裝置等來處理，很容易得_維長極短 之纖維素纖維’特別是含大量纖維長G 35mm以下之微細纖維素 纖維之粉碎纖維素。所得之粉碎纖維素，將其控制在例如，纖維 寬為0.15/zm以下，視平均纖維長為〇25mm以下之極微細之程 度亦可能。本發明之吸收體2係將原料之纖維素纖維利用上述方 法予以粉碎並調整為具有纖維長〇 35mm以下之微細纖維素纖維 含量在45質量％以上之纖維集料收容於喷霧罐丨内所形成，隨 後，在吸收體2之上面配置蓋狀構件4之後，灌入喷霧劑3之液 化氣於罐體内而製成噴霧罐製品。 蓋狀構件4係由直徑形成較喷霧罐丨之内徑大之具一定厚度 之圓盤狀多孔質體所構成，圓盤狀多孔質體係壓入喷霧罐丨内固 定而密接於吸收體2之上面以保護其表面平滑。如此，於充填喷 霧劑3時或喷霧使用中時，能保持吸收體2之形狀、定位，而防 14 201125789 纖維素纖維自吸收體2表面處剝落或飛散。圓盤狀多孔質 料了If能將吸收體2側與空間部12側保持可通氣的區隔之材 与可適用。 舉例言，蓋狀構件4之材料可使用具通氣性之纖維集料之不 質不織布可適當選擇其纖維之材質或纖維長而成形具有較硬 m度之形狀’而將此裁斷為所定厚度及所定直徑之圓盤狀以 籍思文盤狀多孔㈣。或者，亦可使㈣所定直徑之不織布布片 j層至所定厚度者。構成不織布之纖維無論是，合成纖維、 '纖、’隹、無機質纖維或再生纖維等任一種均可適用良好。蓋狀 構件4之直徑略大於噴霧罐丨之胴體部之内徑，厚度為，例如可 在5mm〜2〇mm程度之範圍内適當選擇使用。 又，蓋狀構件4之材料，亦可使用例如，將具有多數連續通 孔之發泡烏拉坦樹脂或發泡酚樹脂等之發泡性樹脂發泡成型為 所望厚度及餘之大小形狀，或者，將發域型體麟成為所要 形狀而得之蓋狀構件4。 蓋狀構件4亦可為在吸收體2之表面形成一體之多孔質保護 層。例如，將吸收層2收容於噴霧罐丨内之後，自將安裝噴出口 11之上部開口注入發泡性樹脂，使之發泡而形成密貼於吸收體2 之上面之多孔質保護層。在此情形下，發泡性樹脂層只要構成能 將吸收體2之上面覆蓋之外，也能密接喷霧罐丨内壁，而將吸收 體2穩定保持定位者即可，此時，不必要將其形成一定之厚度。 因此，使用於形成多孔質保護層之發泡性樹脂量不必多，等待發 泡成型之時間亦可縮短。 構成如上之吸收體2及盘狀構件4因不必使用表面膜片咬袋 15 201125789 子包覆’且發泡性樹脂之使用量亦少，因此可廢低 如在壓縮成型之吸收體2表面積層不織布之右;•斗成本又 體2—體之多孔質保護層亦可行。 '、收 本發明如應用於塵埃吹喷器時1霧劑3以使用含有可 液化氣之二甲趟為主成分之液化氣體非常適合。做為喷霧劑成八 之二甲喊係以化學# CH3〇CH3表示之最簡單之醚，為彿： -25.1°C之無色氣體，因化學性安定’在贼時之飽和蒸氣壓為 0.41MPa，35t時之飽和蒸氣壓為〇,688 MPa，略加壓力、即容易 液化，故喷霧罐1不必使用如耐高壓強度之氣罐容器，可充^於 耐壓強度較低之金屬製喷霧罐内使用。 、 上述二曱社臭氧層具有破壞係數為Q，地球暖化係數為i 以下之極小值，即使喷於大氣中’在大氣中之分解時間約數十小 時程度’無慮產生溫室效果或臭氧層破壞，故做為比以往使用之 敗利昂氣體或HFC134a或HFC152a等環境負担小之喷霧劑3來 使用，非常合適。 又’嗔_ 3並不限於H只要對臭氧層破壞或地球暖 化之影響小之可用氣體’無洽疋可燃性氣體、難燃性氣體均能適 用。尤其是，臭氧層係數為〇，且不含氣氟碳化合物之氣體，即 能滿足綠色購人法之「判斷基準」而非常適宜。這種氣體並無破 壞臭氧層之虞，且對環境之負担比習用之代替氟利昂小。二甲醚 等之氣體，無論是單獨使用，或併用或做為含有他種氣體成 混合氣來使用均可行。 二甲醚因係可燃性’如使用於習用構造之喷霧罐製品之噴霧 劑時，有漏液致發生火災之危險，唯利用本發明之吸收體2吸收 16 201125789 保持，並於其表面配置蓋狀構件4而能大幅提高保液性能，因 此，只有經由通氣性之蓋狀構件4進入上方空間部12之氣化氣 體從喷出口 11噴射而出，無液狀之喷霧劑漏出之情形，故殆無 引火之虞。又，因吸收體2穩定的被保持定位於喷 霧罐1内，使用角度不受限制，於是能以傾斜狀態或倒立狀 態使用，且因抑止使用時或保管時之漏液效果高，安全性高。 本發明之喷霧罐製品如應用於火焰喷燈（喷火燈）用氣罐

下，裝填於喷霧罐1内之本發明之吸收體2及蓋狀構件4亦如前 述同樣可吸收保持液化氣而防止漏液發生，因此具有可大幅提高 傾斜狀態或顛倒狀態使用時或保管時之安全性之效果。 其次，參照第2、3圖就上述構成之喷霧罐製品之製造方法 之一較佳實例說明如下： 第2圖表示將廢紙解纖製成吸收體2之情形為例之製造流程 之示意圖。首先，在（1)、（2)之粉碎工程中，將廢紙微粉碎成為

Description of the Invention: [Technical Field] The present invention relates to a spray can product in which a liquefied gas and a liquid-retaining absorbent body are filled in a spray can provided with a discharge port, and particularly to a can. A spray can product filled with a dust blower sprayer and a gas canister for a flame blower filled with a combustible gas, and a method of manufacturing the same. [Previous Technology] A product using a spray can, such as a dust blower (dust remover), is filled with a compressed gas or a liquefied gas in a metal spray can having a spray button or a trigger. The canister of the spray is sprayed with gas by pressing the spray button or by pulling the trigger to blow off the dust attached to various machine types. In the past, sprays containing spray cans of such dust blowers have been frequently treated with Freon gas, which is an extremely strict use of ozone depleting substances. For this reason, the industry has turned to the development of spray agents with a lower ozone layer destruction coefficient. Now, there are so-called alternative Freon's such as HFC134a (CH2F-CF3) and HFC152a (CH3-CHF2). However, HFC134a has the advantage of no burning fire due to its incombustible gas, but its global warming coefficient is as high as 1300. As for the HFC152a (CH3-CHF2), the global warming coefficient is only 140, but it is a flammable gas, and it must be used with caution. In addition, these alternative gases are expensive and are fluorides, such as exposure to fire. It will produce highly toxic hydrofluoric acid, so there is a considerable problem with the safety of use. On the one hand, in recent years, the concern for the global environmental protection is soaring, not only the destruction of the ozone layer, but also the environmental pollution caused by the discharge of gas in the county. In particular, the impact of the two-ball warming cannot be ignored. In the law of the Green Procurement Law, which promotes the purchase of clothing materials by the government, etc., the items that are negative for the surrounding environment, such as the greenhouse effect gas, which is discharged, are designated as "environmental articles", and the dust blower (dust blower) In response to this trend, its "judgment criteria" has been revised from "the second year of the second year of the second year of the second year of the second year of the year to "the use of the ozone-depleting substance f and the hydrofluoride-breaking compound (the so-called replacement of freon)". The use of alternative Freon products is no longer listed as an "environmental item" that can be used to mark the green production method of Dongzixiang, and as a spray that satisfies the revised "judgment criteria", there is no ozone layer damage and global warming. DME, which has a very small coefficient, is the most attractive. However, dimethyl is called a flammable gas, and there is a problem in safety when it is used or stored. Also, a flame lamp used in various operations using a flame (torch) The gas tank used is usually a metal pressure vessel having a spray can shape having a discharge portion, and is provided with a gas tank filled with a fuel such as a combustible gas or a liquefied fuel gas, and The fuel injected into the spouting part is introduced into the fire-breathing head. The fuel for the burner is mostly made of the above-mentioned dimethyl ether or heat, and the amount of carbon dioxide (c〇2) contained in the combustion exhaust gas is less than that of petroleum or coal. Liquefied petroleum enthalpy without ozone layer breakage (7). Gas cylinders for fire-fighting lamps also have the same composition as dust blowers, and the use of flammable gases is particularly important for safety requirements and considerations. a spray can product using a liquefied gas. Usually, a pulverized fiber such as ancient waste paper is used as an absorbent body in a spray can, but if it is used in an inverted state or in an inclined state, the liquefied gas is self-contained in a liquid state. When the discharge port leaks out, there is a possibility of igniting. In order to solve this problem, the present inventors have proposed in the patent document that dimethyl ether and carbonic acid gas are used as other components to impart a spray in the dust blower. Opacity 201125789 is flame retardant. Although dioxane is flammable, its ozone layer destruction coefficient and global warming coefficient are extremely small, and it can improve safety after mixing with carbonic acid gas (Patent Document 1: Open Patent Publication No. 2005-206723) Also, in the present invention, like Patent Document 2, a spray can absorb the proposed system to the obtained pulverized cellulose wood pulp fibers constituting the aggregate, the absorbent body contains long fiber 0. The fine cellulose fibers of 35 mm or less are more than or equal to the above. Since such an absorbent body contains minute fibers which are pulverized mechanically or chemically by the cellulose fibers, it has excellent absorption properties and liquid retention properties. (Patent Document 2: JP-A-2008-180377) The porous absorbent synthetic resin described in Patent Document 3 to Patent Document 5 is known, and is used, for example, in Patent Documents 3 and 4. Poly urethane resin (polyamine phthalate resin) foam, which is formed by injecting a raw material resin into a can to foam it, thereby eliminating the filling process. Further, in Patent Document 5, a foam of a phenol resin is used, and the phenol resin foam is molded in a can shape, and then pressed into a can. (Patent Document 3: Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. a gas tank for a blowtorch (spray lamp), and even if it is applied to a spray of a dust blower, if only carbonic acid gas is added to impart flame retardancy, the weight ratio of the carbonic acid gas must be increased, then the spray can The required compressive strength needs to be increased, and the manufacturing cost of the spray can is accordingly increased. Dust blowers are often used in an inclined state or in an inverted state, and there is a tendency for continuous blowing of dust, dust, and the like to effectively blow away dust. Therefore, if the weight ratio of the carbonic acid gas used is small, it is quite difficult to achieve continuous injection in order to maintain the state of complete gasification. Moreover, if the carbon 201125789 acid gas is mixed with dimethyl ether at a high weight ratio, it is not easy to maintain a uniform mixing state in the spray can. When used, the carbonic acid gas will first escape and the quality of the product will be difficult to maintain. There is a sense of derogation and use. The absorbent body of Patent Document 2 contains a large amount of fine powdery fine cellulose fibers, and it is easy to contain air during the defibration and pulverization of the raw material pulp, which is not easy to handle. Therefore, according to the conventional method, it is difficult to load the absorber of the necessary weight into the spray can. In fact, most of the microfibers are stacked on the sheet by the wet method, and then rolled up into a shape according to the shape of the can. After the roll is filled in the can; or the micronized fiber is added with a binder to bond the fiber and the fiber, the molding process is complicated. Further, when the binder is added, the cost is increased, and at the same time, when the binder is applied to the surface of the fiber in a film form, the absorption performance is lowered, and all of the above are disadvantages. There is also a method in which fine fibers collected by a dust collector are stacked and then placed in a bag made of a non-woven fabric or the like, and it is difficult to say that the bagging and sealing operations are time-consuming, and workability and productivity are not good. The absorbent body formed of the porous foamed synthetic resin of Patent Documents 3 to 5 requires not only time for foam molding but also expensive raw material resin and high finished product. Further, although the porous foamed synthetic resin has excellent liquid retention properties, the residual gas tends to stay in the spray can, and it is difficult to use it all at the end, which is also a problem. In view of the above problems, an object of the present invention is to provide a spray can product which can prevent liquid leakage when the product is used or stored in an inclined state or in an inverted state, and can ensure safety even when flammable liquefied gas is used. And the liquid retention property, at the same time, it is not necessary to use expensive raw materials or complicated manufacturing engineering, thereby reducing the cost and improving the workability, productivity and economy; and the object of the present invention is also to manufacture the spray can product. The method. 201125789 In order to solve the aforementioned problems, the solution provided by the present invention has the following constitution. That is, the invention of claim 1 of the present application is a spray can product in which a spray tank having a discharge port is filled with a liquefied gas and an absorbent body for liquid retention; characterized in that the absorption system is composed of a fiber length 1. a cellulose fiber aggregate having a cellulose fiber of 5 mm or less and 90% by mass or more, wherein the spray can has a space portion on the discharge port side and a compression molding shape corresponding to the spray can body portion. In the block-shaped absorbent body, a lid member having a gas permeable property to protect the surface of the absorber is provided between the space portion and the absorber. According to the present invention, the compression molding into the block-shaped absorbent body and the lid member thereon can prevent the spray can from leaking when used or stored in an inclined state or in an inverted state. At this time, the upper surface of the absorber directly filled in the spray can is sealed by the lid member, so that when the liquefied gas or the spray is used, the fine powdery fine cellulose fibers do not scatter, even if liquefied liquefaction is used. Gas also ensures safety and liquid retention. Further, since it is possible to reduce the cost by using expensive raw materials or complicating the manufacturing process, it is possible to provide spray can products which are excellent in workability, productivity, and economy. According to the invention of claim 2, the lid member is press-fitted into the spray can to adhere to the disk-shaped porous body on the surface of the absorber. The cap-shaped member is closely attached to the upper surface of the absorber in the spray can, so that the absorber is sealed from the upper space portion, and the displacement of the absorber is stopped to ensure the space portion, and the fine cellulose fiber can be effectively prevented. Flying. According to the invention of claim 3, the lid member is integrally formed on the surface of the absorbent body as a porous protective layer. 201125789 Since the lid member is integrally formed with the absorbent body, the shape of the absorbent body can be surely sealed, and the space inside the spray can is ensured, and the fine cellulose fibers can be effectively prevented from scattering. According to the invention of claim 4, the disk-shaped porous body or the porous protective layer of the lid member is made of a nonwoven fabric or a foamable resin. The cap member is made of a foamable resin or a non-woven fabric using a porous air permeable material, and the material is relatively free. According to the invention of claim 5, the absorbent system is previously formed by compression molding the cellulose fiber aggregate into a cylindrical block-shaped molded body corresponding to the shape of the spray can, and directly loading the spray can. Since the cellulose fiber aggregate can be previously processed into a can-shaped compression-molded body, it is easy to assemble and fill in the can, and the manufacturing process is simplified. According to the invention of claim 6, the liquefied gas is a combustible liquefied gas. The spray can product for internally charging a combustible gas is particularly effective in the present invention, which not only prevents liquid leakage but also greatly improves safety. According to the invention of claim 7, the liquefied gas ozone layer has a zero coefficient of destruction and is composed of a gas containing no hydrofluorocarbon. Since the liquefied gas system uses a gas that does not particularly destroy the ozone layer and contains no hydrofluorocarbons, the environmental impact can be minimized. According to the invention of claim 8, the absorption system is composed of a fiber length of 0. A cellulose fiber aggregate of 45 mass% or more of fine cellulose fibers of 35 mm or less is used. The cellulose fiber aggregate constituting the absorbent body, if the cellulose fiber having a shorter fiber length is more than a predetermined amount, is more liquid-repellent. According to the invention of claim 9, there is provided a method for producing a spray can product having a discharge port and internally filled with a liquid 201125789 gas and an absorbent body for liquid retention, comprising the following items: mechanically pulverizing the raw material fiber into a fiber-containing material Long l. Engineering of cellulose fiber aggregates of more than 90% by mass of cellulose fibers of 5 mm or less; after the cellulose fiber aggregates are quantitatively measured, they are compressed in the radial direction of the spray can to form a spray can a shape having a shape corresponding to a block-shaped compression molded body as an absorbent body; and pressing the absorbent body into the can from the upper opening of the spray can, pressing the disk-shaped porous body into the spray can The inside is placed close to the above absorber. The surface, or the porous protective layer is integrally formed on the upper surface of the above-mentioned absorbent body as a cover member, and a space portion is formed on the upper portion of the cover member. According to the above production method, even when the absorbent body contains a large amount of fine powdery fine cellulose fibers, the absorbent body is radially compressed into a bulk compression body having the same shape as the can body, and then placed in the can, and the second cover is placed. The member can be used as a member, and therefore, it is possible to efficiently manufacture a product in which the absorber is directly filled in the spray can. At this time, the absorber is directly compressed in the radial direction of the spray can, and the directly loaded absorbent body maintains a uniform density in the spray can, thereby improving the liquid retention performance, and the cover member is reused on the absorbent body. Sealing, it can prevent the fine fibers of the absorber from scattering, so that high-quality spray can products can be produced. According to the invention of claim 10, there is provided a method for producing a spray can product having a discharge port and internally filled with a liquefied gas and a liquid retaining absorbent body, comprising the following items: mechanically pulverizing the raw material fiber to have a fiber length of 1 . The engineering of the cellulose fiber aggregate of 90% by mass or more of the cellulose fiber of 5πΗη or less; after the cellulose fiber aggregate is quantitatively measured, it is compressed in the radial direction of the spray can to substantially form the shape of the spray can. a shape that is equivalent to the block compression molded body 201125789 as an absorbent body; and the above-mentioned absorption after pressing the bottom opening of the lid member spray can formed by the disk-shaped porous body into the can The body is pressed into the bottom opening to make it closely follow the lid member, and a space portion is formed on the upper portion of the lid member. According to the above method, the absorber is radially compressed and formed into a block-shaped compressed body having the same shape as the can body, and then loaded into a can in which the cap member is first disposed in the can. Therefore, the manufacturing process can be simplified. Efficient manufacturing of spray cans that have been directly filled with absorbent articles. Moreover, since the absorber is compressed in the radial direction of the spray can beforehand, the absorbent body can maintain a uniform density in the spray can after the loading, and the liquid retaining property b' can be improved and the cover member can be reused on the absorbent body. Sealing and rubbing prevent the fine fibers of the absorbent body from scattering, so that high-quality spray can products can be produced. [Embodiment] Hereinafter, the spray can product of the present invention and a method for producing the same will be described in detail based on specific embodiments. The spray can product of the present invention can be applied as long as it is a spray can product in which a spray can having a discharge port is filled with a liquefied gas and a liquid retaining absorbent. Specific examples are, for example, a blower for dust removal (dust blower) or a gas torch for flame blower (spray lamp). As a typical representative example, the use of the dust blower here is described in detail with reference to the accompanying drawings. Fig. 1(a) is a schematic view showing the overall configuration of the dust blower, and shows a structure in which the head portion of the spray can 1 is fixed to have an ejection portion la having a jet trigger ratio. Figs. 1(b) and 1(c) show that the inside of the spray can 1 contains the absorber 2, and the spray 3 of the liquefied gas is absorbed by the absorber 2. The metal spray can has a crucible body having a diameter of 疋 and a frustum-shaped head having a downwardly expanding diameter, and a discharge port 11 is provided at the center of the top surface of the head. The discharge port u constitutes a structure that can be depressurized by the injection trigger lb 10 201125789 to open the valve to eject the gas. The absorber 2 is compression-molded into a cylindrical block having a diameter which is substantially the same as the inner diameter of the spray can, and the orientation is slightly shorter than the equal diameter body of the spray can 1, and the space is left on the head side. The state of the portion 12 is housed in a spray can. The liquefied gas 3 as a spray is contained in the spray can 1 in a state in which it is absorbed and held by the gap between the pulverized cellulose fibers constituting the absorbent body 2 and the fibers, and when the discharge trigger is opened, the discharge port U is opened. The spray gas can be ejected from the nozzle lc to remove the dust. At the near upper end of the body portion of the spray can 1, a cover member 4 is provided to separate the space portion 12 from the absorber 2. The absorbent body 2 is not coated with any film or bag as a skin, and is directly filled in the spray can 1, and the cover member 4 is adhered to the upper surface of the compression-molded absorbent body 2, and this surface is attached. Covered. With such a configuration, the lid member 4 is insurable. The surface of the absorbent body 2 is made to be ventilated, and at the same time, the displacement of the absorbent body 2 is prevented to prevent the fine cellulose fibers on the surface from scattering. - In the present invention, the absorbent body 2 is composed of a fiber length of 1. A cellulose fiber aggregate having a cellulose fiber of 5 mm or less and 90% by mass or more. The fiber of cellulose fiber is fixed at 1. It is 5 mm or less, and is compressed and compressed into a fiber aggregate to be filled in the spray can 1 to be closed, and becomes a liquefied gas which can absorb and store a desired amount, and can improve liquid retention and improve safety. Preferably, the cellulose fiber aggregate contains a fiber length. 80% or more of the cellulose fibers of 0 mm or less are more effective. In particular, it contains cellulose. When the fine cellulose fibers having a diameter of 35 mm or less are 45 mass% or more, the ij ij can further improve the absorption performance and the holding power of the liquefied gas, and the spray can 1 can be prevented from leaking when used in an inclined or inverted state or during storage. Therefore, it is better. In the present invention, the term "fiber length" means the average fiber length measured by a fiber length measuring machine FS-200 (manufactured by Kayani Co., Ltd.). 11 201125789 Absorber 2 is a fiber which is obtained by defibrating, pulverizing and miniaturizing the raw material containing cellulose fibers. The fine cellulose fiber of 35 mm or less is an absorber of the main body. The pulverization of the cellulose fibers can be carried out by means of mechanical or chemical means (devices) or both. A more suitable means is a method of pulverizing and classifying by mechanical means, whereby a fine cellulose fiber aggregate containing a desired fiber length of fine cellulose fibers at a predetermined content can be obtained simply. Cellulose fibers which can be used as raw materials for the absorbent body 2, such as cellulose fibers such as needle tree, bleached or unbleached chemical pulp of broadleaf trees, dissolving pulp, waste paper pulp, and even cotton. It is also possible to use a plurality of kinds of the above-mentioned cellulose fiber raw materials in a suitable mixture. These raw materials are pulverized to have a desired fiber length, and are suitable for use in the absorbent body of the present invention. Needle tree bleached kraft pulp (NBKP) and broadleaf bleached kraft pulp (LBKP) are very suitable because of their excellent absorption, liquid retention and excellent liquefied gas coloration. Waste paper pulp has a low cost and a small burden on the environment. The waste paper pulp originally has problems in that the liquid retention property of the fiber is slightly inferior, and the fiber adheres to the printing ink. However, as long as the present invention, a large amount of the pulverized fiber length is used. 5mm or less, preferably 1. The cellulose fiber under 0mm is the main body, especially the fiber length is 0. It has been confirmed that the fine cellulose fibers of 35 mm or less are compressed and molded and directly loaded into the absorbent body 2 composed of the spray can 1 to achieve a very good liquid retention property. It is presumed that after the cover body 2 is directly loaded into the spray can 1 , the fine cellulose fibers are uniformly spread around the spray can 1 , and the liquefied gas can be uniformly stored in the entire interior of the absorbent body 2 . Improve the liquid retention performance. If the waste paper pulp is too damaged or old, it can be increased by the length of the fiber. The content or the amount of the fine cellulose fibers of 35 mm or less or the amount of the cellulose fibers to be used alone or in combination with the other raw material 12 201125789 pulp is preferably adjusted to obtain the liquid retention property of the desired period. The mechanical pulverization method of the cellulose fiber as a raw material is mainly a high-speed impact pulverization method such as a rotary mill or a jet mill, and a crusher pulverization method. In the preceding stage, it can also be coarsely pulverized by the shearing and breaking method such as a tearing machine. Further, the fiber by-product (lower leg) obtained when producing other fiber products can be used in the same manner. For example, when manufacturing a pulp blown laminate non-woven fabric, the cellulose fiber recovered from the bag filter contains a large amount of fine cellulose fibers, and therefore, this can be directly used as a raw material or mixed with other cellulose fibers to obtain a desired cellulose fiber. Aggregate to use. This makes it easy to simplify the manufacturing process. The processing conditions of the pulverizer used may be appropriately selected depending on the physical properties of the required fine cellulose fibers; and the treatment method may be carried out in any of batch or continuous manner; In a series, the rough processing is performed first in the first stage, and the fine processing is performed in the final stage. Further, the cellulose fibers pulverized in advance using a mechanical device are sorted to have a fiber length of 1. The cellulose fiber of 5 mm or less is 90% by mass or more, or preferably the fiber length is 1. The cellulose fiber of 0 mm or less is 80% by mass or more, and more preferably the fiber is long. It is also possible to use 45 mass% or more of fine cellulose fibers of 35 mm or less. Alternatively, after classification, it can be mixed with any other cellulose fiber to have a fiber length of 1. Below 5mm, preferably the fiber length is 1. The cellulose fiber below 0mm is adjusted, or it will have a fiber length of 〇. The fine cellulose fibers of 35 mm or less are adjusted to have a desired amount, and are also used in combination. Further, when the fiber length is soft due to the organic substance, and only depends on the mechanical pulverization treatment, if it is difficult to obtain the fine cellulose particles, in order to obtain the fine cellulose fibers, a combination of chemical treatment and mechanical treatment may be employed. deal with. In general, the fiber 13 201125789 is composed of a crystalline field and a non-crystalline field, and is not a knot reaction. Therefore, a chemical treatment such as a reaction with a mineral acid to dissolve a non-domain 2 to obtain a cellulose fiber of a crystal body is obtained. As a method, it has been known that the cellulose fibers of the main body of the crystallized portion are further mechanically finely divided into cellulose particles. Text · 1 piece In addition, the Lee (four) mixing type wet material machine can be pulverized. The medium-mixing-type wet pulverizing device is a device that is inserted into a fixed pulverizing container and is smashed in a south-speed rotation of the smashing container to crush the medium and the cellulose fiber lining to generate a breaking stress. There are tower type, trough type, flow tube type, Manzo pull type, etc. 'But' as long as it is the medium (four) method, no matter which device is used. Among them, the use of a sand mill, an ultra-adhesive mill, a paper refiner, and a diamond refiner are very good. When the paper is processed by the above-mentioned pulverizing apparatus or the like, it is easy to obtain a cellulose fiber having a very short length, particularly a pulverized cellulose containing a large amount of fine cellulose fibers having a fiber length of 35 mm or less. The resulting pulverized cellulose is controlled, for example, to have a fiber width of 0. Below 15/zm, depending on the average fiber length, the degree of fineness of 〇25mm or less is also possible. In the absorbent body 2 of the present invention, the cellulose fibers of the raw material are pulverized by the above-described method, and the fiber aggregate having a fiber length of 35 mm or less and a fine cellulose fiber content of 45% by mass or more is contained in a spray can. After forming the lid member 4 on the upper surface of the absorbent body 2, the liquefied gas of the spray 3 is poured into the can body to form a spray can product. The lid member 4 is composed of a disc-shaped porous body having a diameter larger than the inner diameter of the spray can, and the disc-shaped porous system is press-fitted into the spray can and fixed to the absorber. 2 above to protect its surface smooth. Thus, the shape and positioning of the absorbent body 2 can be maintained when the spray agent 3 is filled or during use, and the cellulose fibers are peeled off or scattered from the surface of the absorbent body 2 in 2011. The disc-shaped porous material is applicable to a material capable of keeping the absorber 2 side and the space portion 12 side ventilable. For example, the material of the cap member 4 can make the non-woven fabric of the aerated fiber aggregate suitable for the fiber material or the fiber length to form a shape having a harder m degree, and cut the thickness into a predetermined thickness and The disk shape of the predetermined diameter is porous (4). Alternatively, it is also possible to make (4) a non-woven fabric sheet of a predetermined diameter to a predetermined thickness. Any of the fibers constituting the nonwoven fabric may be suitably used in any of synthetic fibers, 'fibers', 隹, inorganic fibers or recycled fibers. The diameter of the lid member 4 is slightly larger than the inner diameter of the body portion of the spray can, and the thickness is, for example, suitably selected within the range of 5 mm to 2 mm. Further, as the material of the lid member 4, for example, a foaming resin such as a foamed urethane resin or a foamed phenol resin having a plurality of continuous through holes may be foam molded into a desired thickness and a size of the remaining shape, or The cap-shaped member 4 is obtained by forming the hair-type body lining into a desired shape. The lid member 4 may also be an integral porous protective layer formed on the surface of the absorbent body 2. For example, after the absorbent layer 2 is housed in the spray can, the foamed resin is injected from the upper opening of the attachment discharge port 11 and foamed to form a porous protective layer adhered to the upper surface of the absorbent body 2. In this case, the foamable resin layer may be configured to cover the inner surface of the spray can 2 in addition to the upper surface of the absorbent body 2, and the absorbent body 2 may be stably held and positioned. It forms a certain thickness. Therefore, the amount of the foamable resin used for forming the porous protective layer does not have to be large, and the time for waiting for foam formation can be shortened. The absorbent body 2 and the disk-shaped member 4 which are configured as described above are not required to be coated with the surface film biting bag 15 201125789, and the amount of the foaming resin is also small, so that the surface area of the absorbent body 2 which is compression-molded can be reduced. The right side of the non-woven fabric; • The cost of the body and the porous protective layer of the body 2 can also be used. In the present invention, when applied to a dust blower, the aerosol 3 is suitably used as a liquefied gas containing dimethyl hydrazine containing a liquefiable gas as a main component. As a spray, it is the simplest ether represented by Chemistry #CH3〇CH3. It is a Buddha: -25. A colorless gas at 1 °C, due to chemical stability, the saturated vapor pressure at the time of the thief is 0. 41MPa, the saturated vapor pressure at 35t is 〇, 688 MPa, a little pressure, that is, easy to liquefy, so spray tank 1 does not have to use a gas tank container such as high pressure strength, can be filled with metal with low compressive strength Use in spray cans. The above-mentioned Ershisha ozone layer has a coefficient of destruction of Q, and the global warming coefficient is a minimum value of i or less. Even if it is sprayed into the atmosphere, the decomposition time in the atmosphere is about several tens of hours, and there is no greenhouse effect or ozone layer destruction. It is very suitable as a spray 3 which is less environmentally burdened than a conventionally used gas or a HFC134a or HFC152a. Further, '嗔_3 is not limited to H. The gas that can be used as long as it has little effect on the destruction of the ozone layer or the global warming. ‘No flammable gas or flame retardant gas can be used. In particular, a gas having an ozone layer coefficient of 〇 and containing no gas fluorocarbons is very suitable for satisfying the "judgment criteria" of the green purchase method. This gas does not damage the ozone layer, and the burden on the environment is smaller than the conventional replacement of Freon. A gas such as dimethyl ether may be used alone or in combination or as a mixture of other gases. Dimethyl ether is flammable. For example, when it is used as a spray for spray can products of conventional construction, there is a risk of fire due to leakage. Only the absorbent body 2 of the present invention absorbs 16 201125789 and is disposed on the surface. Since the lid member 4 can greatly improve the liquid retention performance, only the vaporized gas that has entered the upper space portion 12 via the permeable cover member 4 is ejected from the discharge port 11 and the liquid-free spray leaks. Therefore, there is no fire. Further, since the absorbent body 2 is stably positioned and positioned in the spray can 1, the use angle is not limited, so that it can be used in an inclined state or an inverted state, and the liquid leakage effect at the time of use or storage is suppressed, and safety is ensured. high. When the spray can product of the present invention is applied to a gas canister for a flame torch (spray lamp), the basic constitution is still the same as described above, and only the absorber 2 in the spray can 1 absorbs and maintains flammability liquefaction as a fuel. The gas is different from the spray 3 of the aforementioned dust blower. This fuel is supplied to a flame burner having an ignition portion connected to the head of the spray can 1, and can be used for various operations using a torch or a flame. The fuel for the burner lamp is preferably a high-calorie liquefied petroleum gas (LPG) which has a lower CO 2 content than the petroleum or coal-burning exhaust gas and has no ozone layer destruction problem. Mixtures using dimethyl ether alone or in combination with other combustible liquefied gases may also be used. In this case, the absorbent body 2 and the lid member 4 of the present invention which are filled in the spray can 1 can also absorb and hold the liquefied gas as described above to prevent the occurrence of liquid leakage, and therefore can be used in a state in which the inclined state or the inverted state can be greatly improved. The effect of safety at the time of storage or storage. Next, a preferred example of the method for producing the spray can product of the above configuration will be described below with reference to Figs. 2 and 3: Fig. 2 is a view showing a manufacturing process in which the waste paper is defibrated into the absorbent body 2 as an example. . First, in the pulverizing works of (1) and (2), the waste paper is finely pulverized into, for example, a fiber length of 0. Fine cellulose fibers of 35 mm or less. In the work of (1), a coarse pulverizer is used to pulverize, for example, waste paper into a coarse angle of 20 to 30 mm, and in (2), a fine pulverizer is used for further fine pulverization. 17 201125789 When the scrap is passed through the micro-pulverizer, the fiber length changes according to the size of the outlet screen... Here, for example, the export screen with the mesh size of 0 3 〇~0 , is used, and the desired mesh can be obtained. Crushed fiber of fine cellulose fibers. The dust collection process 'collects and accumulates fine cellulose fibers. The dust collector of the figure has a rotating wing at the bottom, and only the upper part is provided. The fine cellulose fiber of 35_ or less is passed through the screen, and the compressed air is introduced into the mist, so that the fine cellulose fibers thus collected are dropped, and the shutters are provided on the bottom portion (partially not shown). Take out the discharge opening. In the project of (4), the discharged fine cellulose fibers are transported to the next project by means of four reduction conveyors (not only one representative on the drawing) which are respectively connected to the discharge ports of the above four shutters. The volume reduction conveyor has a wide width at the end of the take-up port and gradually narrows toward the front. The powder containing fine cellulose fibers can be slightly compressed and reduced in volume while being conveyed. The volume reduction conveyors are respectively connected to the engineering weight measuring machine of (5), and the powder portion after the volume reduction is transported thereto. The weighing machine is equipped with a measuring device (weighing device), and when the weight of the fine cellulose fiber powder reaches the necessary amount of the spray can product, the valve is automatically opened and the powder is supplied to the appropriate amount. A project. Then, in the project of (6), the scaled powder is reduced in volume and compressed into a fiber aggregate, which is loaded into the spray can in the project. The works of (6) and (7) are shown and described in more detail in Figure 3. As shown in Figure 3(a), the quantitative powder that has been completed in (4) and measured by the weighing instrument (5) is sent to the plastics in the volume reduction compression molding project (6). The inside of the compression container 5 in the form of a cubic container is compressed and compressed there. As shown in the figure, the compression container 5 is formed such that the wall surface can be moved horizontally and parallelly, firstly moved in the direction shown in the figure to apply a compression, and then moved in the direction of the crucible to apply secondary compression while the 18 201125789 body is rushed. The two corners of the cube are concentrated to form a substantially cylindrical shape ==. Then, the bottom of one corner of the compression vessel 5 is, for example, set to borrow =: ’ ‘ and the spray can 1 is placed under the discharge opening, the fiber aggregate, . After the pre-compression, the discharge port is opened and pushed out from its aggregate. From the top, the piston push rod 6 is used to push the fiber into the spray tank 1 below the two-axis cylindrical absorber 2 as shown in the figure. At this time, the push rod 6 is used. To push the absorbent body 2 into the spray can 1 ' Therefore, it should be noted that the compression of the push direction is not excessive. Thus, as shown in Fig. 3(b), the absorbent body 2 formed of a substantially cylindrical bulk compression molded body which is subjected to an average compression compression in χ and γ (4) can be obtained. The absorbent body is formed as a pre-compressed molded body which is press-compressed in the direction of x and Y#i in the radial direction of the spray can, and can be directly filled in the state of the spray can. Good shape retention and improved liquid retention. When the absorbent body 2 is directly loaded into the spray _ i, the absorbent body 2 does not have to be uniformly compressed (triaxial compression) in all directions, but instead, the pushing direction of the push rod 6 is applied (ie, the spray can 1 is applied). When the axial direction is compressed, it is not suitable because the liquefied gas is injected to cause cracks between the fibers and cause longitudinal cracking. Here, the absorber 2 is exemplified by a block-shaped compression molded body which is biaxially compressed in the X and γ-axis directions, and is only required to be uniformly compressed in the radial direction, that is, "T", for example, The absorber 2 composed of a cylindrical block-shaped compression molded body in which the entire circumference of the radial direction is compressed toward the center (inner side) of the hollow direction is also possible. The spray can product of the present invention can be obtained by further arranging the cover member 4 on the upper surface of the absorbent body 2. Fig. 4 (a) to (c) show the types of spray cans, and Fig. 4 (a) shows the body portion 13 and the bottom portion 14. The head portions 15 are individually formed, and are respectively joined by the curling edge 19 201125789. a two-piece spray can; FIG. 4(b) is a two-piece spray can in which the body portion 13 and the head j $ are integrally formed, and the bottom portion I4 of the individual is joined to the lower portion of the body portion 13 by the crimping edge; Fig. 4(c) shows a one-piece spray can in which the body portion 13 and the bottom portion 14 and the head portion 15 are integrally formed. In the spray can of the three-piece spray can of Fig. 4(a), after the bottom 14 is crimped, the upper end opening of the body 13 is aligned before the head 15 is crimped. The bottom of the compression container 5 in which the absorbent body 2 is housed is opened, and is placed in close contact with each other on the coaxial core line. Then, the absorbent body 2 is pushed out and loaded into the spray can 1. Then, the lid member 4 formed of a disk-shaped porous body made of a non-woven fabric or a foamable resin is press-fitted, and the surface of the absorber 2 is adhered to the surface of the absorber 2, and then the head portion 15 is crimped and joined. As shown in Fig. 4(d), the cover member 4 and the spray can product of the absorbent body 2 are sequentially placed in the trunk portion 13 from the side of the head portion 15 toward the bottom portion 14. In the spray can of the two-piece spray can of the fourth figure (b), the order of the above is reversed, that is, the cover member 4 is pressed into the head 15 side from the bottom 14 side, and then The lower end opening of the hole portion 15 is aligned with the bottom opening ' of the compression container 5 accommodating the absorbent body 2, and is disposed in close contact with each other on the concentric line. Then, the absorbent body 2 is pushed out and loaded into the spray can 1. Subsequently, the bottom portion 14 is crimped to obtain a spray can from the head portion 15 side to the bottom portion 14 side as shown in Fig. 4(d), and the lid member 13 and the absorbent body 2 are sequentially mounted in the body portion 13. product. Further, in the configuration of the spray can shown in Figs. 4(a) and 4(b), a porous protective laminate layer formed of a nonwoven fabric or a foamable resin may be formed before the absorber 2 is pushed out. The surface of the head, then 'fill this absorbent body together with the porous protective layer in the spray can. 0 20 201125789 As for the single-piece spray can of Figure 4 (c), it will be in the above (6) In the volume reduction compression molding process, the two-axis compression absorber 2 is intended to be applied to the compression container 5, and the outer twisting energy and the inner diameter of the opening of the head portion 15 are formed, and the cylindrical block formed by compression compression is compressed. The molded body is filled in the can from the opening of the neck portion 15 to obtain the absorbent body 2 having a predetermined weight. Then, as shown in Fig. 5 (4) and (b), after the surface of the absorbent body 2 is flattened into a substantially planar shape, the foaming resin material constituting the lid member 4 is injected to expose the surface of the absorbent body 2. After evenly covering, it is foamed. Thus, as shown in Fig. 5(e), the lid member 4 for protecting the surface of the absorbent body 2 is formed on the upper surface of the absorbent body 2, and is spaced apart from the space portion 12 formed above. In the configuration of the spray can shown in Figs. 4(a) and 4(b), the lid member 4 can also be formed by this method, and it goes without saying. As shown in the above, according to the method of the present invention, since the combination of the dry pulverization method and the compression compression molding method is adopted, the absorbent body 2 which has been formed of the fine cellulose fibers can be easily and easily filled into the spray. A spray can product having a structure in which the lid member 4 is adhered to the inside of the can body 2 and on the absorbent body 2. According to this method, the workability is good, which is suitable for mass production, and at the same time, it is excellent in economy and productivity. [Example 1] In order to confirm the effects of the present invention, an absorbent body was produced in accordance with the manufacturing operations shown in Figs. 2 and 3 to form a spray can product. In the pulverization process of (1) and (2), the raw materials of the absorbent body are coarsely pulverized and finely pulverized into finely pulverized fibers, and sent to the dust collection project of (3) for classification and recovery. And the resulting content contains 〇. The micro-powdered cellulose fibers of the fine cellulose fibers of 35 mm or less are piled up to a predetermined amount; then, in the works of (4) and (5), the micro-powdered cellulose fibers taken out from the dust collector are used for volume reduction conveyors. After the volume is reduced, it is transferred to the measuring and cutting machine to be re-cut to obtain a fine powdery cellulose fiber aggregate of 85 grams by weight; then, the obtained micro-powdered cellulose fiber aggregate is collected in (6) In the engineering, the cylindrical bulk compression molded body is obtained by reducing volume compression molding. The cylindrical block-shaped compression molded body thus obtained was pushed into the spray can shown in Fig. 4 (a) as an absorbent body in the process of (7). The spray can has an outer diameter of 66 mm and a height of 20 cm. The outer bottom of the can is wound into the lower end of the body to be closed and fixed, and the absorbent body is filled into the can from the upper end opening of the crotch portion, and then the spray can is formed in advance. The disc-shaped lid member having a slightly larger inner diameter of the body is pressed into the can until it contacts the upper surface of the absorber. The lid member is formed by laminating a non-woven fabric of a predetermined diameter, and has a diameter of 60 mm and a thickness of 10 mm. Thereafter, the top (head) of the can is wound around the upper end opening of the body portion. Further, in the case of the fiber length distribution of the cellulose fiber aggregate as the absorbent body, the fiber length and the shape measuring device side amount analysis result were used to obtain a fiber length of 1. The cellulose fiber content of 5 mm or less is 90% by mass or more, and the fiber length is 1. The cellulose fiber content of 0 mm or less is 80% by mass or more, and the fiber length is 0. The cellulose fiber content of 35 mm or less is 45% by mass or more. 350 ml (ml) of a flammable liquefied gas of dioxyl ether was charged as a spray in a spray can to prepare a dust blower of the spray can product of the present invention, followed by a liquid leakage evaluation test. The test method and test results are as follows: [Leakage evaluation test] The dust blower is placed after the spray is filled in the spray can for a sufficient period of time, the container is inverted and jetted, and the measurement starts from the spray section. The time when liquid leakage occurred. As a result, it was measured that the ink leakage prevention was maintained for more than 30 seconds in the inverted state. When the cover is used in a dust blower, the flammable gas used as a dust blower will ignite, which is considered to be caused by the fact that the liquefied gas is not completely vaporized during the injection of 22 201125789; There is almost no use in the case where the dusting time is more than 20 seconds, especially in the case of continuous spraying for more than 30 seconds, the temperature drop due to the heat of vaporization makes it difficult for the operator to bear the light to hold the can. For the sake of the present invention, when the present invention is applied to a dust blower, it has been confirmed that it can be used as a safe and effective effect as long as it is used in accordance with general dust removal purposes. [Example 2] Next, in the same manner as in Example 1, an absorbent body was prepared using a commercially available LBKP as a raw material, and a spray can product was prepared. At this time, the lid member was formed by laminating a disk-shaped nonwoven fabric used in Example 1, and the thickness thereof was 8 mm, 10 mm, and 15 mm, respectively (both diameters were 60 mm). Further, in the case of the fiber length distribution of the cellulose fiber aggregate as the absorbent body, the fiber length and the shape measuring device side amount were used to analyze the result. The cellulose fiber content of 5 mm or less is 95% by mass or more, and the fiber length is 1. The cellulose fiber content of 0 mm or less is 90% by mass or more, and the fiber length is 0. The content of the fine cellulose fibers of 35 mm or less is 60% by mass or more. After the absorbent body 75g and the lid member were loaded into the spray can as in the first embodiment, 350 ml (ml) of flammable liquefied gas of dimethyl ether was sprayed into the spray can as a spray to prepare the spray of the present invention. Dust blower for can products. After a plurality of test samples were prepared using spray can products of three different thickness cap members, a liquid leakage evaluation test (number of samples N = 5) was performed. As a result, in the case of a thickness of 8 mm and 10 mm, four of the five samples were able to be continuously sprayed without leaking for more than 30 seconds. In the case of a thickness of 15 mm, all of the five samples can be continuously sprayed without leaking for more than 30 seconds. It can be seen from the above that according to the present invention, it is possible to provide a dust sprayer or a flame blower which is free from the use of a flammable gas, and is safe to use because of the leakage of the 201123789 liquid. It is excellent in sex and use, and it can manufacture spray can products at low cost.
