阅读说明：本技术 密封袋及其使用方法 (Hermetic bag and its application method ) 是由 王永铭 王崇贤 于 2017-05-31 设计创作，主要内容包括：一种密封袋,包括袋体(11)以及设置在袋体(11)上的第一夹链(12)、第二夹链(13)与泄气装置(14),其中袋体(11)具有容置空间(111)和连通该容置空间(111)与外界的开口(11a),第一夹链(12)用以封闭该开口(11a),第二夹链(13)用以将容置空间(111)分隔为第一次空间(111a)与第二次空间(111b),且第一次空间(111a)位于第一夹链(12)与第二夹链(13)之间,泄气装置(14)设置于第一夹链(12)与第二夹链(13)之间用以将该第一次空间(111a)中的气体导引至外界,泄气装置(14)使该第一次空间(111a)趋近于真空,使大气施加于袋体(11)的外力大于第二次空间(111b)中因为气体膨胀而施于袋体(11)向外撑开的力,第二夹链(13)始终维持关闭状态。(A kind of hermetic bag, including bag body (11) and the first clip chain (12) being arranged on bag body (11), second clip chain (13) and air releasing device (14), wherein bag body (11) has accommodating space (111) and is connected to the accommodating space (111) and extraneous opening (11a), first clip chain (12) is to close the opening (11a), second clip chain (13) is to be divided into first time space (111a) and second of space (111b) for accommodating space (111), and first time space (111a) between the first clip chain (12) and the second clip chain (13), air releasing device (14) is set between the first clip chain (12) and the second clip chain (13) the gas in the first time space (111a) is directed to the external world, it lets out Device of air (14) makes the first time space (111a) level off to vacuum, it is applied to atmosphere in greater than second space (111b) of external force of bag body (11) and imposes on the outside distracted power of bag body (11) because of gas expansion, the second clip chain (13) remains off state always.)
