opening side of the bag body 10 but IOa thoroughly as possible air between the article and the exhaust-side IOb discharge clean air to obtain an exhaust gas substantially drain the bag .  而在现有技术中，通常是在物品通过一个开口放入排气袋产品中后，再通过该开口或设置在该开口附近的排气阀用排气泵将排气袋产品中的空气抽干净，这时因为放入的物品与开口之间的气压突然减少，导致物品会靠近所述开口，所述袋体10的内表面会与所述物品相接触，并且排气袋产品远离开口的那一侧的空气还没未完全排出，便因为物品本身的阻挡而没有充分排尽，从而产生了很多滞留有空气的角落。  In the prior art, usually after the article is placed in the exhaust gas through an opening in the bag, and then through the opening or openings provided in the vicinity of the exhaust valve with an exhaust pump in the exhaust gas bag drawing air cleaner, because the air pressure between the time an article is placed with the opening suddenly decreased, resulting article will close the opening, the inner surface of the bag body 10 will be in contact with the article, and the exhaust away from the bag that the air side of the opening is not yet completely discharged, because they block the article itself is not sufficiently drained, resulting in a lot of corners with air retention. 而在本实施例，通过开口侧IOa放入物品，另外的一个排气侧IOb排气，所述容纳空气101内靠近所述排气侧IOb远离所述开口侧IOa的空气，同时也是所述容纳空气101内主要的空气部分得以迅速排出，从而最大程度地减少了残留在所述袋体10内的空气，减少了所述物品与所述袋体10内表面之间形成的还滞留有空气的角落。 In the present embodiment, through the open side into the article IOa, IOb another one exhaust side exhaust, the air contained within the air 101 near the exhaust side IOb IOa away from the opening side, but also the receiving rapidly discharge the air within the main air section 101, so as to minimize the residual air within the bag 10, but also reduces the retention of air is formed between the article and the inner surface of the bag body 10 corner of.  如图2和图3所示，具体地，每个所述单向止回阀20可以包括两阀膜21和22，并且设置在所述袋体10的内部，以在两阀膜21和22之间形成一个排气通道23。  As shown in FIG. 2 and FIG. 3, in particular, each of the two-way check valve 20 may include a membrane 21 and a valve 22, and is disposed inside the bag body 10, two valves in the film an exhaust passage 23 is formed between 21 and 22. 所述两个阀膜21和22各自具有贴合在所述袋体10的两个相对的内表面上一个内侧端211和221，以及自由的外侧端212和222。 The two valves 21 and 22 each have a film bonded to the bag body on two opposing inner surfaces 10 of the outer 211 and 221, and the free end 212 and an inboard end 222. 在本优选实施例中，所述两个阀膜21和22各自的内侧端211

另外，在所述袋体10邻近所述单向止回阀20那一侧还可以沿一个端热封处1400热封，所述端热封处1400与所述两个侧向热封处1100和1200之间留有空隙，以形成了所述排气口103。 Further, the bag body 10 adjacent to the one-way valve 20 may also be in a side end of the 1400 heat-sealing heat-sealing, heat sealing at the end of 1400 and 1100 at the two lateral heat-sealing leaving a gap between the 1200 and to the exhaust port 103 is formed. 形成的排气袋上在没有热封线的那一侧形成了开口102，沿着所述开口102在所述袋体10上设置所述开合机构，以密封或打口所述开口102，这样整个排气袋就制成了。 Pockets formed in the exhaust side of the heat seal line is formed without opening 102, the opening 102 along the bag body 10 is provided on the closure means, to seal the opening 102 or play port, Thus the entire exhaust bags produced.  值得一提的，本发明的排气袋可以用广泛用于体积较大，重量较轻的产品的包装运输，例如羽绒服，棉被等，其可以大在的节约运输体积与成本。  It is worth mentioning, the exhaust gas pouch of the present invention can be widely used in a larger volume, lighter weight packaging and transportation of products, such as jackets, blankets and the like, which can save the cost of shipping a large volume in the.  如图6所示是根据本发明的上述优选实施例的另外一种变形实施方式，与上述实施例一样，所述排气袋包括袋体IOA和至少一单向止回阀20A。 The embodiment is another modified embodiment of the above-described preferred embodiment of the present invention, the above embodiment  As shown in FIG 6, the exhaust gas bag comprises a bag body IOA and at least one-way check valve 20A. 所述袋体IOA包括两个袋体层IIA和12A以形成容纳空间101A，开口102A，排气口103A。 IOA said bag body comprises two layers IIA and bag 12A to form an accommodation space 101A, the opening 102A, the exhaust port 103A. 所述单向止回阀20A包括两阀膜21A和22A以形成排气通道23A并且在排气后形成的止回通道24A。 20A comprises a two way check valve 21A and check valve membrane to form channels 22A and 23A formed in the exhaust passage of the exhaust gas after-24A.  在本实施例中，所述袋体IOA在邻近所述两阀膜21A和22A的所述外侧端212A和222A处还设置有多个阻隔封合处16A，相邻的两个所述阻隔封合处16A形成曲折的缓冲空间17A，这样在空气从所述容纳空间IOlA中排出时，空气到达所述缓冲空间17A中进入到所述止回空间24A，从而使所述止回空间24A中存在一定的空气压力以作用在所述单向止回阀20A的所述外侧端部以密封所述单向止回阀20A的排气通道23A，并且所述排气袋外部的空气也不容易通过曲折的缓冲空间17A进入到所述排气通道23A，从而进一步起到密封的作用。  In the present embodiment, the bag body adjacent to the IOA film 21A and the two valves 212A and 222A at the outer end 22A is further provided with a plurality of barrier at the seal. 16A, the two adjacent述阻隔封合处16A形成曲折的缓冲空间17A，这样在空气从所述容纳空间IOlA中排出时，空气到达所述缓冲空间17A中进入到所述止回空间24A，从而使所述止回空间24A中存在一定的空气压力以作用在所述单向止回阀20A的所述外侧端部以密封所述单向止回阀20A的排气通道23A，并且所述排气袋外部的空气也不容易通过曲折的缓冲空间17A进入到所述排气通道23A，从而进一步起到密封的作用。  更具体地，所述阻隔封合处16A可以是各种形状，如Y形，H形，T形，等等，作为一个举例，在本实施例中，所述阻隔封合处16A包括一条主封合线161A，和分别从所述主封合线161A延伸出来的第一侧封合线162A和第二封合线163A,相邻两个所述阻隔封合处16A 的所述第一第侧封合线162A没有重合在一起，而是形成有间隔164A，从而使得空气可以从这些间隔164A达到所述排气口103A，然后进一步排出。这样所述袋体IOA外的空气不容易从这些阻隔封合处16A形成的缓冲空间17A到达所述单向止回阀20A处，进一步防止了空气反渗的可能。并且，因为有这些阻隔封合处16A的阻隔作用，当所述容纳空间IOlA的气体从所述单向止回阀20A的排气通道23A排出时，能够形成具有一定气压的所述止回空间24A,以用于在排气完成时密封所述排气通道24A。  如图7和图8所示是根据本发明另外一个实施例的单向止回阀20B的结构示意图，与上述实施例一样，所述排气袋包括袋体IOB和至少一单向止回阀20B。所述袋体IOB 包括两个袋体层IlB和12B以形成容纳空间101B，开口102B，排气口103B。  每个所述单向止回阀20B包括位于外侧的第一阀膜21B和第二阀膜22B以及位于内侧的一个止回阀膜25B，所述止回密封膜25B重叠于所述第一阀膜21B和所述第二阀膜22B的内侧端，以在所述第一阀膜21B和所述止回阀膜25B之间形成一个排气通道23B，并在所述止回阀膜25B和所述第二阀膜22B之间形成一止回通道26B。  如图8所示，当所述容纳空间IOlB受挤压以向外排出空气时，所述排气通道22B 用于向外排气以形成填充有气体的止回空间24B，直至气压使所述第一阀膜21B和所述第二阀膜22B的外侧端重叠并密封以关闭所述排气通道23B。根据本优选实施例，当有气体从所述第一阀膜21B和所述第二阀膜22B的外侧端之间想要进入所述容纳空间IOlB时，空气被导引进入所述止回通道26B，以产生补充气压，从而进一步密封所述排气通道23B，以补偿所述第一阀膜21B和所述第二阀膜22B的密封效果的不足。  所述止回阀膜25B也是薄层柔性膜。优选地，所述止回阀膜25B，所述第一阀膜21B 和所述第二阀膜22B为聚乙烯（PE)膜。另外，每个所述袋体层IlB和12B的厚度大于每个所述第一阀膜21B，所述第二阀膜22B和所述止回阀膜25B的厚度。  根据本发明的优选实施例，所述止回阀膜25B的长度小于每个所述第一阀膜21B 和所述第二阀膜22B的长度，从而当所述止回阀膜25B重叠于所述第一阀膜21B和所述第二阀膜22B的内侧端时，所述第一阀膜21B和所述第二阀膜22B的外侧端重叠在一起。  值得一提的是，当通过所述排气通道23B向外排气时，所述排气通道23B内的空气流向与所述止回通道26B的空气流向相反，因此，空气不会进入所述止回通道26B。当空气想要返回所述排气通道23B时，空气进入所述止回通道26B以产生补充气压进一步密封所述充气通道23B。  相应地，在制作过程中，所述第一阀膜21B和所述第二阀膜22B之间放置有所述止回阀膜25B，并且所述第二阀膜22B和所述止回阀膜25B的内侧端与所述袋体层22热封在一起，所述第一阀膜21B的内侧端与所述袋体层21热封在一起，并且所述第一阀膜21B与所述止回阀膜25B之间有耐热物，从而在热封过程中没有热封在一起而形成所述排气通道23B，所述第二阀膜22B与所述止回阀膜25B之间也设置有耐热物，从而在热封过程中没有热封在一起而形成所述止回通道23B。
