Description

包裝袋保鮮排氣閥結構
本發明係有關一種乾燥食品在包裝袋中包裝，能增延保存期限的包裝袋保鮮排氣閥結構。
按，人們對物品的保鮮要求越來越高，一般除以冷凍、冷藏方式抑制細菌滋長外，若可將空氣、濕氣隔離，亦是避免食物受潮變質的方式之一；然傳統的包裝袋用於乾燥食品包裝，包裝袋一開封便無任何可再封合之構造，至多係在於袋口設有夾鏈，供暫時封閉袋口，避免食品落出或可防止蟑螂或其他蟲類進入袋內污染食物，但由於袋中仍存有大量的空氣，因此袋中的食品(如咖啡、茶葉等)仍容易受潮變質；習用如中華民國公告第M564875號「包裝袋之阻氣閥」新型專利案，是在包裝袋上設若干出氣孔，將一阻氣閥貼合固設在包裝袋內側的出氣孔對應處；透過阻氣閥的容室內容置一被若干擋塊擋止限位的膜片對容室底面的若干氣孔貼附(阻氣)，俾包裝袋受擠壓，空氣由氣孔上推膜片，再經出氣孔的排氣，藉袋內外形成壓力差，使膜片吸附貼蓋在氣孔來防止外界空氣及濕氣進入包裝袋；雖然上述習知阻氣閥，能以包裝袋擠壓方式將袋內空氣排出外界，同時可以阻止外界空氣進入袋內，減少空氣或濕氣對食品造成氧化變質影響，唯，單靠包裝袋的袋體擠壓方式，僅能將袋內包裝空隙處的大部份空氣排出外界，袋內或多或少必定會殘留下少許空氣，這些少許空 氣，仍然對食品的變質或新鮮度造成影響，甚至難以掌握或預期食品的安全保存期限。
本發明之主要目的係在提供一種包裝袋保鮮排氣閥結構，係一排氣閥，包括有一閥體，一閥片及一份保鮮劑；該閥體，係以一隔板將內部空間間隔形成一閥室及一填充室；該隔板上設有一個以上通孔，使該閥室與該填充室之間經由該通孔相通；該閥片，係組裝在該閥室內，且該閥室的開口端外周緣，徑向外凸有一貼合邊框，該貼合邊框的表面上，並設有一封口薄膜，將該閥片限制在該閥室內；該份保鮮劑，係裝填在該填充室內，該填充室的入口端，設有一透氣薄膜，且該透氣薄膜的外表面端，並設有一密封薄膜；平時，該排氣閥的填充室內所裝填的該份保鮮劑，是由該封口薄膜及該密封薄膜的密封，阻止外界空氣或濕氣進入填充室，令該份保鮮劑的有效成份得以長時保存；當乾燥食品欲採用具有該排氣閥的包裝袋進行包裝時，該包裝袋製作過程，僅須打開該密封薄膜，並將該封口薄膜的表面貼合在該包裝袋內部的紙面上，通過該紙面上對應該閥室進行打孔，形成貫穿該封口薄膜出氣孔，造成該閥室可經由該出氣孔與外界相通；如此，該包裝袋封口完成乾燥食品的包裝時，該包裝袋內部對乾燥食品包裝所存在的空隙，透過該包裝袋外部的擠壓，除能利用該閥體的閥室內閥片在該通孔位置作外移離開與回位關閉動作，單向造成空隙中空氣，穿過保鮮劑及通孔，從包裝袋的出氣孔擠壓排出外界外，包裝袋中未被擠壓排出所殘留下來的空氣，藉由填充室內保鮮劑可通過透氣薄膜往包裝袋的袋體內部，對包裝袋中殘留的空氣產生除濕或脫氧作用，能夠減少 或避免殘留空氣對乾燥食品造成變質影響，有效增延乾燥食品在包裝袋中包裝的保存期限。
本發明之次一目的係在提供一種包裝袋保鮮排氣閥結構，其中，該閥體內之隔板一端表面上，係貼設有一過濾薄膜，且該過濾薄膜並覆蓋在該通孔的一端孔口位置上，藉由該過濾薄膜對該填充室內的保鮮劑形成外漏擋止，俾使閥室內避免有保鮮劑粉粒進入，確保閥片單向關閉通孔的動作正常，長時發揮良好排氣逆止效果。
本發明之再一目的係在提供一種包裝袋保鮮排氣閥結構，其中，該閥體的填充室入口端，係設一階級口部，該階級口部上，由內而外，依序貼設該透氣薄膜及該密封薄膜，使該透氣薄膜與該密封薄膜之間形成有一空隙；藉由穿針在該密封薄膜上穿刺時，針頭僅會進入該空隙而不會傷及透氣薄膜造成破損，俾使填充室內保鮮劑，能由密封薄膜上刺孔形成通氣孔，簡易完成與包裝袋內部互通的打開動作。
本發明之另一目的係在提供一種包裝袋保鮮排氣閥結構，其中，該填充室的入口端，係在該透氣薄膜的外表面端上黏貼可離型的該密封薄膜，藉由該密封薄膜可從透氣薄膜的外表面端上單獨撕起拆除，俾使填充室內保鮮劑，僅須由入口端上撕開去除密封薄膜，即可簡單完成與包裝袋內部互通的打開動作。

本發明為達上述目的，特舉較佳實施例，並配合所附圖式，作詳細說明如下：一種包裝袋保鮮排氣閥結構，如圖1、2、3，係一排氣閥10，包括有一閥體20，一閥片30及一份保鮮劑40；該閥體20，係以一隔板21將內部空間間隔形成一閥室22及一填充室23；該隔板21上設有一個以上通孔24，使該閥室22與該填充室23之間經由該通孔24相通；該閥片30，係組裝在該閥室22內，且該閥室22的開口端外周緣，徑向外凸有一貼合邊框25，該貼合邊框25的表面上，並設有一封口薄膜26，將該閥片30限制在該閥室22內；該份保鮮劑40(可以是乾燥劑或脫氧劑)，係裝填在該填充室23內，該填充室23的入口端，設有一透氣薄膜27，將該份保鮮劑40包裝在該填充室23內，且該透氣薄膜27的外表面端，並設有一密封薄膜28；如圖3，平時(用於保鮮袋前)，該排氣閥10的閥體20填充室23內所裝填的該份保鮮劑40，是由該封口薄膜26及該密封薄膜28的閥體20內部密封，阻止外界空氣或濕氣進入填充室23，令該份保鮮劑40的有效成份得以長時保存備用；當乾燥食品(圖未示)欲採用具有該排氣閥10的包裝袋進行 包裝時，該包裝袋製作過程，如圖4、5，僅須打開該密封薄膜28(例如打孔打開填充室23)，並將該封口薄膜26的表面貼合在該包裝袋50內部的紙面上，通過該紙面上對應該閥室22進行打孔，形成貫穿該封口薄膜26出氣孔51，造成該閥室22可經由該出氣孔51與外界相通；如此，該包裝袋50封口(袋口封閉)完成乾燥食品的包裝時，該包裝袋50內部對乾燥食品包裝所存在的空隙，透過該包裝袋50外部的擠壓，除能利用該閥體20的閥室22內閥片30在該通孔24位置作外移離開與回位關閉動作，單向造成(包裝)空隙中空氣，穿過保鮮劑40(註：保鮮劑40一般是以粉粒樣態呈現，因此，允許空氣通過)及通孔24，從包裝袋50的出氣孔51擠壓排出外界外，包裝袋50中未被擠壓排出(外界)所殘留下來的空氣，在閥片30關閉通孔24的狀態下，如圖6，藉由填充室23內保鮮劑40可通過透氣薄膜27往包裝袋50的袋體內部，對包裝袋50中殘留的空氣產生除濕或脫氧作用，能夠減少或避免殘留空氣對乾燥食品造成變質影響，有效增延乾燥食品在包裝袋50中包裝的保存期限。
根據上述實施例，其中，如圖1、3，該閥體20內之隔板21一端表面上，係貼設有一過濾薄膜29，且該過濾薄膜29並覆蓋在該通孔24的一端孔口位置上，藉由該過濾薄膜29對該填充室23內的保鮮劑40形成外漏擋止，如圖5，俾使閥室22內避免排氣過程中，有保鮮劑40粉粒(劑)外漏進入，如圖6，確保非排氣狀態時閥片30單向關閉通孔24的動作正常(不受阻擾)，長時發揮良好排氣逆止效果。
根據上述實施例，其中，如圖1、2、3，該閥體20的填 充室23入口端，係設一階級口部230，該階級口部230上，由內而外，依序貼設該透氣薄膜27及該密封薄膜28，使該透氣薄膜27與該密封薄膜28之間形成有一空隙231；藉由穿針(圖未示)在該密封薄膜28上穿刺時，針頭僅會進入該空隙231而不會傷及透氣薄膜27造成破損，如圖4、5，俾使填充室23內保鮮劑40，能由密封薄膜28上刺孔形成通氣孔280，簡易完成保鮮劑40與包裝袋50內部(乾燥食品)互通的填充室23打開動作。
根據上述實施例，其中，如圖1、2、3，該填充室23的入口端，係在該透氣薄膜27的外表面端上黏貼可撕開離型的該密封薄膜28，藉由該密封薄膜28可從透氣薄膜27的外表面端上單獨撕起拆除，如圖3、7，俾使填充室23內保鮮劑40，僅須由入口端上撕開去除密封薄膜28，即可簡單完成保鮮劑40與包裝袋50內部(乾燥食品)互通的填充室23打開動作。
以上說明，對本發明而言只是說明性的，而非限制性的，本領域普通技術人員理解，在不脫離所附說明書所限定的精神和範圍的情况下，可做出許多修改、變化或等效，但都將落入本發明的保護範圍內。
