Description
該弁体は仕切板で内部空間を弁室及び充填室に仕切る。該仕切板上には一個以上の通孔を穿設し、該弁室と該充填室の間を該通孔を経て連通させる。該弁片は該弁室内に組立設置し、且つ該弁室の開口端外周縁は、径方向外向きに貼合わせフレームを有し、該貼合わせフレームの表面には封止フィルムを設置し、該弁片を該弁室内で制限する。該鮮度保持剤は、該充填室内に装填し、該充填室の入口端には通気フィルムを設置し、該鮮度保持剤を該充填室内に設置してもよく、且つ該通気フィルムの外表面端には密封フィルムを設置する。
包装袋の鮮度保持排気弁構造は、図1、2、3に示すとおり排気弁10であり、弁体20、弁片30及び鮮度保持剤40を含む。該弁体20は仕切板21で内部空間を弁室22及び充填室23に仕切る。該仕切板21上には一個以上の通孔24を穿設し、該弁室22と該充填室23の間を該通孔24を経て連通させる。該弁片30は該弁室22内に組立設置し、且つ該弁室22の開口端外周縁は、径方向外向きに貼合わせフレーム25を有し、該貼合わせフレーム25の表面には封止フィルム26を設置し、該弁片30を該弁室22内で制限する。
乾燥食品(図未提示)を該排気弁10を備えた包装袋で包装したい時、該包装袋の過程において、図4、5に示すとおり、該密封フィルム28(例として孔を開けて充填室23を開く)を剥がすだけでよく、更に該封止フィルム26の表面を該包装袋50内部の紙面に貼り合わせ、該紙面上で該弁室22に対応して孔を開け、該封止フィルム26の貫通した排気孔51を形成し、該弁室22は該排気孔51を経て外界と相通じる。

- 排気弁であり、弁体、弁片及び鮮度保持剤を含み、
該弁体は仕切板で内部空間を弁室及び充填室に仕切り、該仕切板上には一個以上の通孔を穿設し、該弁室と該充填室の間は該通孔を経て連通させ、
該弁片は該弁室内に組立設置し、且つ該弁室の開口端外周縁は、径方向外向きに貼合わせフレームを有し、該貼合わせフレームの表面には封止フィルムを設置し、該弁片を該弁室内で制限し、
該鮮度保持剤は、該充填室内に装填し、該充填室の入口端には通気フィルムを設置し、該鮮度保持剤を該充填室内に設置し、且つ該通気フィルムの外表面端には密封フィルムを設置する包装袋の鮮度保持排気弁構造において、そのうち、
通常、該排気弁の充填室内に装填した該鮮度保持剤は、該封止フィルム及び該密封フィルムの密封によって、外界空気もしくは湿気が充填室に進入するのを止め、該鮮度保持剤の有効成分を長時間保ち、乾燥食品は該排気弁を備えた包装袋で包装する時、該包装袋の包装過程において、該密封フィルムを剥がし、更に該封止フィルムの表面を該包装袋内部の紙面に貼り合わせ、該紙面上で該弁室に対応して孔を開け、該封止フィルムに貫通させた排気孔を形成し、該弁室には該排気孔を経て外界と相通じることを特徴とする包装袋の鮮度保持排気弁構造。 - 前記弁体内の仕切板一端表面には濾過フィルムを貼着し、且つ該濾過フィルムは該通孔の一端孔口位置に被覆し、該濾過フィルムが該充填室内の鮮度保持剤によって外漏れを止めることを特徴とする請求項1記載の包装袋の鮮度保持排気弁構造。
- 前記弁体の充填室入口端には階段口部を成形し、該階段口部は内から外向きに該通気フィルム及び該密封フィルムを順に貼着し、該通気フィルムと該密封フィルム間に隙間を形成し、刺針が該密封フィルムに刺した時、針頭が該隙間に入るだけで傷つけず、通気フィルムを破損させないことを特徴とする請求項1記載の包装袋の鮮度保持排気弁構造。
- 前記充填室の入口端は該通気フィルムの外表面端に剥離可能型の該密封フィルムを粘着し、該密封フィルムを通気フィルムの外表面端から単独で剥がして取り除くことができることを特徴とする請求項1記載の包装袋の鮮度保持排気弁構造。
