Description

流体包装袋及其应用 技术领域
本发明涉及一包装袋,尤其涉及一流体包装袋,其中该流体包装的壁上设置有至少一透气孔,以使被包装的产品与外界环境进行气体交换。
背景技术
现今科技日新月异、交通四通八达,各种电子产品、陶瓷塑料产品、化学医药产品、食品等不断的被制造、生产或种植并且被消费者购买,而从生产至到达消费者的手中的运输和储存过程中,常常难免有损伤,因此,对于这些产品或物品的保护或者包装是一个重要的议题。
现今大部分包装方案常采用一般气体缓冲垫进行物品的保护或者包装,或者通过若干个气室壁围绕成一个可以容纳待包装物品的容纳腔,各气室壁可以包含一个或多个气室用以缓冲,当所述待包装物品放置在所述容纳腔中时,所述气体包装袋的所述气室能够从不同方向给待包装物品提供气体缓冲作用,以防止所述待包装物品在受到撞击或跌落等过程中遭到损坏。
现有的这种包装袋,一般会形成一个容纳腔。为方便放置和运输,多数商品被设置为规则的形状。相应地,该容纳腔的形状多与常见的板状、柱状、长方体状包装物品的形状相适应。然而,自然界有许多东西生来便具有其独特的形状,其中保存和运输过程中需要以其特有的形状存在并需要受到保护,例如葡萄。一串葡萄的形状是不规则的,将一串葡萄防止于一具有长方体状容纳腔的包装箱时,通常需要在其周围垫一些能够提供缓冲作用的纸张等缓冲材料,以防止其在包装箱内晃动并遭受损坏。多串葡萄被排列于同一包装箱时,其也容易因相互碰撞而遭受损坏。因此,葡萄,作为一种容易损坏的商品,其包装和运输着实令人苦恼。水果的损坏不仅仅使果农长久的心血付诸东流,造成浪费,而且其损坏产生的汁液容易对周边的物品和环境造成污染。
另外,随着运输水平的提高,全国各地的生鲜产品如水果和蔬菜都能够从产地运往全国各地的营销地,以满足消费者的需求。尤其是随着现代物流业的飞速发展,使消费者能够在网上下单购买生鲜产品如水果和蔬菜。而这些生鲜产品如水果和蔬菜从产地运往需求地或者消费者手中的过程中,必不可少的环节就是产品的储存和运输。但是,在这两个环节中,由于生鲜产品如水果和蔬菜的搬运和运输过程中的颠簸,往往会导致生鲜产品如水果和蔬菜之间的相互碰撞和摩擦, 这就不可避免的会导致生鲜产品如水果和蔬菜的损坏。而且损坏的生鲜产品如水果和蔬菜容易遭受微生物的侵蚀,从而导致生鲜产品如水果和蔬菜的腐烂,而且,腐烂的生鲜产品如水果和蔬菜往往会引起其周围的生鲜产品如水果和蔬菜的腐烂,这就会给生鲜产品如水果和蔬菜的所有者带来很大的损失。目前,大部分包装方案常采用若干个气室壁围绕成一个可以容纳待包装生鲜产品如水果和蔬菜的容纳腔,然后将待包装生鲜产品如水果和蔬菜置于该容纳腔内,以为包装在该容纳腔内的生鲜产品如水果和蔬菜从不同方向提供气体缓冲作用,以防止该生鲜产品如水果和蔬菜在受到碰撞或者摩擦时遭到损坏。但是,如果该包装袋用来包装生鲜产品如水果和蔬菜的话,置于该容纳腔内的生鲜产品如水果和蔬菜无法与空气接触,就会进行无氧呼吸,从而会导致生鲜产品如水果和蔬菜的腐烂。
此外,为了保持生鲜产品如水果和蔬菜的新鲜,往往给运输过程中或者存储中的生鲜产品如水果和蔬菜提供冷藏条件,以在一定程度上降低生鲜产品如水果和蔬菜的呼吸作用,从而保持生鲜产品如水果和蔬菜的新鲜。但是,冷链运输或者冷藏无疑会增加生鲜产品如水果和蔬菜的运输和存储成本,而且,如果冷藏后的生鲜产品如水果和蔬菜脱离冷藏条件而与外界环境接触,就会在生鲜产品如水果和蔬菜的表面凝结水滴,就会容易使生鲜产品如水果和蔬菜腐烂。此外,对于消费者直接在网上下单购买的生鲜产品如水果和蔬菜来讲,冷链运输更是难上加难。所以为生鲜产品如水果和蔬菜提供一种经济成本较低的能够使生鲜产品如水果和蔬菜脱冷运输和储存的包装产品是亟待解决的问题。
发明内容
本发明的一个目的在于提供一种流体包装袋,其对包装物品的侧边能够提供加强缓冲效果,从而增强该包装袋整体的安全性,进而对包装物品提供更好的保护。
本发明的另一目的在于提供一种流体包装袋,其中所述流体包装袋能够使包装的生鲜产品如蔬菜、水果和花卉等进行适度的有氧呼吸,从而抑制生鲜产品如蔬菜、水果和花卉的无氧呼吸,从而防止生鲜产品的腐烂,以延长包装产品的保鲜期。
本发明的另一目的在于提供一种流体包装袋,其中所述流体包装袋能够在脱离冷藏条件的情况下运输和储藏该生鲜产品,并且保持其新鲜。
本发明的另一目的在于提供一种流体包装袋,其中被包装的生鲜产品能够被该流体包装袋紧紧包裹起来,从而防止被包装的生鲜产品之间相互碰撞或者摩擦产生损伤。
本发明的另一目的在于提供一种流体包装袋,其中该流体包装袋能够为被包装的产品提供缓冲作用,从而防止该被包装的产品由于跌落或者碰撞而产生损伤。
为了实现上述至少一个目的,本发明提供了一流体包装袋,包括由至少两层流体储存膜形成的至少一流体缓冲体,其中该流体缓冲体包括可储存流体的至少一流体储存单元,其中该流体缓冲体经弯折和塑封形成具有一开口的一容纳腔,以用于容纳至少一包装物品。优选地,该流体包装袋具有至少一连通所述容纳腔和外部环境的透气孔,以供一包装物品尤其生鲜产品的呼吸。另外,该流体缓冲体侧边通过一系列压合缝防止被包装物品接触该流体缓冲体的侧边缘,从而提供加强的侧边缓冲效果。

可以理解的是,术语“一”应理解为“至少一”或“一个或多个”,即在一个实施例中,一个元件的数量可以为一个,而在另外的实施例中,该元件的数量可以为多个,术语“一”不能理解为对数量的限制。
如图1至图43所示是根据本发明的流体包装袋,其具有可填充流体的结构,以在填充流体后可以为各种包装物品如电子产品、食品、医药产品、化工原料、生物材料、塑料陶瓷、快速消费品、照明灯具等提供缓冲效果,而且在未使用时, 可以不填充流体而方便存储和运输,在使用时再现场填充流体,从而使用非常方便。
如图1至图11是根据本发明的第一个优选实施例的一流体包装袋。在本发明的这个优选实施例中,该流体包装袋可以实施为空气缓冲材料,即充入的流体可以是气体,如以空气为例。当然本领域技术人员可以理解的是,在应用中根据需要也可能是其他气体。根据该第一个优选实施例,其在填充流体后可以形成一立体包装袋,从而为一包装物品提供空气缓冲效果。可以理解的是,该流体也可以是液体,如保温液体,从而能够使该流体包装袋具有保温效果。也就是说当该流体包装袋未被使用时,可以不填充流体,从而方便存储和运输;当该流体包装袋使用时,该流体包装袋可以填充流体从而形成一空间结构体,以为各种包装物品如蔬菜和水果等提供缓冲效果。
在本发明的这个优选实施例中,该流体包装袋可以填充气体缓冲材料,如空气缓冲材料,当然本领域技术人员可以理解的是,在应用中根据需要也可能是其他气体。根据该第一个优选实施例,该流体包装袋在填充气体缓冲材料后,可以形成一具有一空间构型的立体包装袋,从而为包装在其中的产品提供气体缓冲效果。可以理解的是,该流体缓冲材料也可以是液体,如保温液体,从而为包装在其中的产品提供一保温效果;该流体缓冲材料也可以是低温液体,从而为被包装在其中的产品提供一低温环境。
值得一提的是,该流体包装袋适于包装各类产品,如电子产品,陶瓷产品,玻璃产品、生鲜蔬果等。在发明的这个优选实施例中,以包装生鲜蔬果如葡萄为例,但是其不构成对该流体包装袋的限制。
根据该第一个优选实施例,该流体包装袋包括至少一流体缓冲体10,即由一个该流体缓冲体10形成一个立体包装袋或多个该流体缓冲体10经塑封连接如粘接或热封形成该立体包装袋。在本发明的图1至图5所示的示例中,其由一个该流体缓冲体10形成。更具体地,参照图1,该流体缓冲体10包括至少两层流体储存膜11和12经一系列平面塑封缝30和立体塑封缝40形成包括一个或多个相连接的流体储存单元13的该立体包装袋,各个该流体储存单元13内形成一个可储存流体的流体储存室14。
本领域技术人员可以理解的是,该平面塑封缝30用于将多层薄膜经塑封形成如图1所示的一个平面缓冲材料,该立体塑封缝40用于将上述平面缓冲材料进一步塑封而使该流体包装袋形成具有空间立体构型并且能够容纳该包装物品的该立体包装装袋,如图3中所示。该平面塑封缝30和该立体塑封缝40可以通过粘接或热封连接的方式将多层薄膜连接在一起,优选地,在这个实施例中,该平面塑封缝30和该立体塑封缝40可以都实施为由热封工艺形成。
根据该第一个优选实施例,该流体缓冲体10进一步地包括至少一流体填充阀20,其可以有合适的阀体形成,如单向机械阀等。参照图8至图11,在这个 实施例中,其是至少两层阀膜21和22形成的该流体填充阀20,该流体填充阀20的该阀膜21和22与该流体储存膜11和12互相叠合地设置,并且在该阀膜21和22之间形成用于向该流体储存室14填充流体的流体填充通道23。可以理解的是,该阀膜21和22的长度短于该流体储存膜11和12。当通过该流体填充通道23向该流体储存室14中填充流体并且该流体储存室14中的压力达到预定要求时,该流体储存室14中的流体压力作用在该阀膜21和22上,以使该阀膜21和22贴合于其中一层该流体储存膜,从而封闭该流体填充通道23,以使该流体填充阀20起到单向阀的作用。
更具体地,如图8中所示,该流体填充阀20包括相对于两层该流体储存膜11和12较短的阀膜21和22,其分别与该流体储存膜11和12相叠合以用于形成向各个该流体储存单元13的该流体储存室14填充流体的流体填充通道23。如图9所示,该流体填充阀20进一步地可以包括增加一层阀膜25,其位于两层该阀膜21和22之间,以用于增强密封性能。如图10所示,该流体填充阀20可以进一步地包括一层补强膜26,其位于一层该流体储存膜12和该阀膜22之间,即位于两层该阀膜21和22的外侧,从而起到防止该阀膜22和该流体储存膜12的相连接处被撕裂,以起到加强其稳固连接的作用。如图11所示,该主通道单元15也可以由该阀膜21和22的外延伸段形成,而其内延伸段与该流体储存膜11和12形成该流体填充通道23。可以理解的是,上述流体填充阀20的具体结构只作为举例而并不限制本发明。
值得一提的是,该流体缓冲体10的该流体储存膜11和12以及该流体填充阀20的该阀膜21和22分别可以由各种合适的薄膜材料制成,如聚乙烯薄膜、聚丙烯薄膜、聚氯乙烯薄膜、聚酯薄膜、聚苯乙烯薄膜或复合薄膜等,本发明在这方面也并不受到限制,只要是合适的柔性薄膜即可。值得一提的是,为了增加单向密封效果,该流体填充阀20的该阀膜21和22也可以是由上述薄膜经添加化学成分而改性得到的自粘性薄膜。
值得一提的是,该流体包装袋可以具有多个该流体填充阀20,如图1至图5所示,也可以仅具有一个流体填充阀20如图6至图7所示,本发明对此不作任何限制。
该流体缓冲体10进一步地包括一主通道单元15,其连接于各个该流体储存单元13,优选地,其一体地延伸于各个该流体储存单元13。更具体地,根据该第一个优选实施例,该主通道单元15与该流体储存单元13的延伸方向相垂直。例如,在这个实施例中,各个该流体储存单元13沿着纵向方向延伸,该主通道单元15沿着横向方向延伸。该主通道单元15形成一主通道151,并且该主通道151具有一填充流体口152,当该填充流体口152的位置设置有填充流体嘴并且执行填充流体操作时,流体从该填充流体口152沿着横向方向进入该主通道151,并且再沿着纵向方向进入该流体储存单元13,并且当该流体储存室14中达到预 定流体压力后,该流体填充阀20的该阀膜21和22贴合于其中一层流体储存膜11或12,从而实现自封闭,以防止充入的流体再反渗进入该主通道151。
可以理解的是,该主通道单元15可以由两层该流体储存膜11和12形成,如图8中所示;也可以由两层该阀膜21和22形成,如图11中所示,或者由其中一层该流体储存膜11或12和其中一层该阀膜21或22形成。
如图1中所示,该平面塑封缝30进一步地包括分别位于该流体缓冲体10的顶侧和底侧的连续密封的一边封缝32和顶侧邻近该边封缝32的一连续密封的主通道密封缝33,其中顶侧的该边封缝32和该主通道密封缝33之间形成该主通道151。可以理解的是,该边封缝32通过塑封工艺如粘接或热封形成并且封合连接两层该流体储存膜11和12。该主通道密封缝33通过塑封工艺如粘接或热封形成并且将两层该流体储存膜11和12和两层该阀膜21和22分别连接在一起,例如通过一次热封工艺而形成的上下两侧的该主通道密封缝33分别将该流体储存膜11和该阀膜21热封连接,以及将该流体储存膜12和该阀膜22热封连接,如图8中所示,并且在除了对应该流体通道23的其他位置将该阀膜21和22也一并热封连接。
如图1中所示,该平面塑封缝30包括一系列导引缝34,其中一个流体填充阀20对应设置两列互相间隔的导引缝34,其由热封连接该阀膜21和22形成,从而在两列该导引缝34之间形成该流体填充通道23。
参照图5,该阀膜21和22进一步地通过多个连接缝35热封连接至该流体储存膜11,这样在该流体储存室14中达到预定的压力时,压力作用于该阀膜21和22,并且因为该连接缝35的设置而同时被压向该流体储存膜11并最终贴合于该流体储存膜11,从而关闭该流体填充通道23。即该连接缝35热封连接两层该阀膜21和22以及一层该流体储存膜11。另外,如图1中所示,各个该连接缝35的形状的设计使得其还进一步地起到防止流体回流的作用,也就是说,当该流体储存室14中的流体想要回流时,会被该连接缝35所阻挡而不能轻易地反渗进入该主通道151。
值得一提的是,根据本发明的该优选实施例的该导引缝34也被将该阀膜连接至该流体储存膜11,以与该连接缝35协同作用,使该流体储存室14中达到预定的压力时,压力作用于该阀膜21和22,以使该阀膜21和22被压向并贴合于该流体储存膜11。
另外,在热封形成这些平面塑封缝30时,该流体填充阀20的该阀膜21和22的该流体填充通道23可以通过设置耐热阻隔装置而形成,在热封工艺之后,再取出该耐热阻隔装置。根据该第一个优选实施例,该流体填充阀20的该阀膜21和22之间设置有一耐热层24,如图8和图11中所示,例如可以是耐热油墨,其贴附于其中一层该阀膜21或22的内表面,这样,在热封形成该主通道密封缝33时,在对应该耐热层24的位置,两层该阀膜21和22不会热封连接,从而该 流体填充通道23得以能够与该主通道151相连通,而不会因热封而将其进入口关闭。
根据该第一个优选实施例,该主通道151由两层该流体储存膜11和12形成,该耐热层24和该阀膜21和22各自有延伸段进入该主通道151,该平面塑封缝30还包括对应于该耐热层24的延伸段的位置的一列互相间隔的沿横向方向排列的接合缝36,因为该耐热层24的设置,该接合缝36将两层该流体储存膜11和12和两层该阀膜21和22分别连接在一起,而两层该阀膜21和22没有热封连接,该接合缝36的设置使得该流体缓冲体10在填充流体时,流体进入该主通道151后,相邻的该阀膜21和22与对应连接的该流体储存膜11和12能够一起膨胀而打开对应的该流体填充通道23。
如图1至图5所示是根据本发明的一个优选实施例的流体包装袋,图1所示是其平面展开示意图,并且该流体缓冲体10在示意的这个实施例中包括一个该流体储存单元13,并且沿纵向方向排列。该主通道单元15沿横向方向排列并与该流体储存单元13一体成形。如图中所示,该流体储存单元13可以被提供由该流体填充阀20形成的多个该流体填充通道23,从而增强流体填充速度和效率。
如图1中所示的沿纵向延伸的该流体储存单元13适合于被对折,从而得到如图6中所示的子流体储存单元131互相叠合的结构,从而该流体缓冲体10形成前侧壁10a和后侧壁10b,然后通过左右两侧的该立体塑封缝40将该流体缓冲体10的左右两侧的前侧壁10a和后侧壁10b的边缘部分相连接,从而在该流体缓冲体10填充流体后,该流体缓冲体10形成具有开口110的容纳腔100,其中包装物品适合于通过该开口110放入该容纳腔100并储存在该容纳腔100中。
可以理解的是,在这个实施例中,该流体缓冲体10被设置有两列该立体塑封缝40,其可以是连续的塑封也可以是断续的塑封。其可以通过一次塑封形成,也可以通过二次塑封形成。本发明在这方面不做限制。
更具体地,该立体塑封缝40包括两条侧封缝41,其分别在该流体包装袋的两端封合连接该前侧壁10a和该后侧壁10b,从而使该流体包装袋形成具有袋状结构。根据本发明的该第一个优选实施例,该侧封缝41为连续的热封缝,从而防止被填充与该流体包装袋的流体溢出。值得一提的是,该侧封缝41可以通过一次热封形成,也可以通过二次热封形成。本发明在这方面不做限制。
如图1所示,该立体塑封缝40进一步包括一系列压合缝42,其塑封连接该流体储存膜11和12以及该阀膜21和22,从而起到压合该流体储存膜11和12以及该阀膜21和22的作用,从而其所在位置便不会被填充流体而膨胀并且其周围部分的膨胀程度相对减弱。
根据本发明的该第一个优选实施例,该压合缝42的形状为长条形,并呈直线排列,从而将该流体储存单元13间隔为不同的子流体储存单元131。多条压合缝42被间隔设置,从而形成一系列连通通道133。被填充于该流体包装袋的 流体能够通过该连通通道流动,进而在其两侧的子流体储存单元131之间进行交换。
具体地,该前侧壁10a包括一前主侧壁101a、一前左侧壁102a、一前右侧壁103a和一前底侧壁104a。该前主侧壁101a与该前左侧壁102a一体连接。该前主侧壁101a与该前左侧壁102a之间设置有一列该压合缝42。该前主侧壁101a与该前右侧壁103a一体连接。该前主侧壁101a与该前右侧壁103a之间设置有另一列该压合缝42。该前主侧壁101a与该前底侧壁104a一体连接。该前主侧壁101a与该前底侧壁104a之间设置有另一列该压合缝42。
该后侧壁10b包括一后主侧壁101b、一后左侧壁102b、一后右侧壁103b和一后底侧壁104b。该后主侧壁101b与该后左侧壁102b一体连接。该后主侧壁101b与该后左侧壁102b之间设置有一列该压合缝42。该后主侧壁101b与该后右侧壁103b一体连接。该后主侧壁101b与该后右侧壁103b之间设置有另一列该压合缝42。该后主侧壁101b与该后底侧壁104b一体连接。该后主侧壁101b与该后底侧壁104b之间设置有另一列该压合缝42。
更具体地,该压合缝42包括一列第一压合缝421、一列第二压合缝422和一列第三压合缝423,其分别被设置于该流体包装袋的左侧、右侧和底侧并分别呈直线排列。
该第一压合缝421、该第二压合缝422和该第三压合缝423分别在左侧、右侧和底侧连接该前主侧壁101a与该后主侧壁101b,以形成具有该容纳腔100的一包装主体101。
此外,该第一压合缝421还热封连接该前左侧壁102a与该后左侧壁102b,从而形成一左缓冲体102。该第二压合缝421还热封连接该前右侧壁103a与该后右侧壁103b,从而形成一右缓冲体103。该第三压合缝421还热封连接该前底侧壁104a与该后底侧壁104b,从而形成一底缓冲体104。该左缓冲体102、该右缓冲体103和该底缓冲体104分别在该包装主体101的左侧、右侧和底侧提供缓冲保护,以增强该流体包装袋的安全性。
值得一提的是,由于该压合缝42被间隔设置,形成该包装主体101的子流体储存单元131与形成该左缓冲体102的子流体储存单元131之间相互连通。被储存于该包装主体101的流体与储存于该左缓冲体102的流体能够通过该连通通道133进行交换。
同样地,形成该包装主体101的子流体储存单元131与形成该右缓冲体103的子流体储存单元131之间相互连通。被储存于该包装主体101的流体与储存于该右缓冲体103的流体能够通过该连通通道133进行交换。形成该包装主体101的子流体储存单元131与形成该底缓冲体104的子流体储存单元131之间相互连通。被储存于该包装主体101的流体与储存于该底缓冲体104的流体能够通过该连通通道133进行交换。
因此,当该包装主体101受到外界压迫时,被储存于其子流体储存单元131的流体能够通过该连通通道133进而该左缓冲体102、该右缓冲体103及该底缓冲体104的子流体储存单元131,从而分散其所受到的压迫,以增强其抗压性,进而增强其安全性。
同样地,当该左缓冲体102、该右缓冲体103或者该底缓冲体104受到外界压迫时,被储存于其子流体储存单元131的流体能够通过该连通通道133进入该包装主体101的子流体储存单元131,从而分散其所受到的压迫,以增强其抗压性,进而增强其安全性。
总之,该压合缝42的设置有利于增强该流体包装袋的安全性。
值得一提的是,上述压合缝42的设置方式、设置位置和设置数量、设置形状都仅仅是对本发明的示例而非限制。根据本发明的其它实施例,上述压合缝42也可以设置为其它的形状、位置和数量。只要能够达到本发明的发明目的,本发明在这方面不做限制。
可以理解的是,在包装时,该流体包装袋的该流体缓冲体10还没有填充流体,将该包装物品从该开口110放入该容纳腔100中。然后,将执行流体填充操作,这时流体进入该流体储存室14,从而该流体储存单元13被填充有流体,从而向内凸出并按压作用于该包装物品的外表面,以形成与该包装物品的形状相适应的凹凸形状。也就是说,该流体包装袋被填充流体后的形状能够匹配被预先设置于该容纳腔100内的包装物品的形状,从而能够被用于包装不同形状的包装物品,并且能够被用于包装不规则形状的物品。
说明书附图之图12至图17阐释了根据本发明的第二个优选实施例的流体包装袋。该流体包装袋包括一流体缓冲体10A和一系列设置于该流体缓冲体10A的流体填充阀20。该流体缓冲体10A包括两层流体储存膜11和12经由一系列平面塑封缝30A和一系列立体塑封缝40A塑封形成的一流体储存单元13A。该流体储存单元13A具有一流体储存室14。
该平面塑封缝30A包括两条边封缝32A、一主通道密封缝33A、一系列导引缝34、一系列连接缝35和一系列接合缝36。该立体塑封缝40A包括两条侧封缝41A和一系列压合缝42A。
该流体缓冲体10A包括一前侧壁10a’和一后侧壁10b’。该侧封缝41A于该流体缓冲体10A的两侧热封该前侧壁10a’和该后侧壁10b’,从而形成具有一开口110A的一容纳腔100A。
与上述第一个优选实施例不同的是,根据本发明的该第一个优选实施例的该压合缝42A的形状为环状,其被设置于该侧封缝41A的附近,以减少其所处位置及其周边的膨胀。根据本发明的该第二个优选实施例,该压合缝42A的数量为六,其分别被设置于该流体包装袋的四个角落处和两侧的中部。这些部位为包装和运输过程中容易受到挤压和膨胀的部位。该压合缝42A的设置使这些部位 的膨胀程度降低,从而其受到外界压迫而遭受破坏的风险降低。
更具体地,该流体包装袋的周边,即其左侧、右侧和底侧是流体填充量相对较少,缓冲保护强度较弱的区域。该压合缝42A的设置使包装物品不会被贴合左右两侧的侧封缝41A以及其底部包装,从而远离缓冲薄弱区。相反地,该流体包装袋的周边受到外界压迫时,周边的流体向中间流动,从而其抗压性得以增强。同样地,该流体包装袋的中间区域受到压迫时,中间的流体也会向周边流动,从而该流体包装袋中部的抗压性也得以增强。也就是说,该压合缝42A的设置使该流体包装袋周边形成了缓存区,从而增加了该流体包装袋的安全性。
值得一提的是,上述压合缝42A的设置方式、数量、位置、形状都仅仅是对本发明的示例而非限制。
如图12至图15所示,该平面塑封缝30A进一步包括至少一定位缝38A。该定位缝38A被设置于该流体缓冲体10A。根据本发明的该第二个优选实施例,该定位缝38A的数量为二并且在该流体缓冲体10A被对折而形成该前侧壁10a’和该后侧壁10b’时,该两个定位缝38A的位置相对应。也就是说,该平面塑封缝30包括塑封连接该前侧壁10a’的一个该定位缝38A,以及塑封连接该后侧壁10b’的一个该定位缝38A,并且两者形成在该流体包装袋的前后侧,并且位置互相对应。值得一提的是,该定位缝38A上述的数量和设置位置仅仅是对本发明的示例而非限制。根据本发明的其它实施例,该定位缝38A也可以是其它的数量和设置位置。其数量和设置位置可以根据包装物品的形状进行设置。
根据本发明的该第二个优选实施例,该定位缝38A位于该流体储存单元13A的中部位置。可以理解的是,该定位缝38A塑封连接至少两层该流体储存膜11和12,从而使得对应该定位缝38A的部分不能填充流体,而其周围的部分可以填充流体,以用于对包装物品起到缓冲作用。
本领域技术人员可以理解的是,该定位缝38A在这个实施例中实施为平面塑封缝,即在未进行立体塑封时即形成该定位缝38A。而在另外的变形中,该定位缝38A也可以在立体塑封步骤中进行,也就是说将该流体缓冲体10A对折以形成该前侧壁10a’和该后侧壁10b’,然后通过塑封机形成该立体塑封缝40和该定位缝38A,在形成该定位缝38A的过程中,如在热封工艺中,该容纳腔100A中设置有耐热阻隔装置,从而避免内侧的流体储存膜,如流体储存膜12,在对折后其内表面被该定位缝38A热封连接,即该定位缝38A只热封连接两层该流体储存膜,而不将四层膜热封连接成一体,从而保证连续贯通地形成该容纳腔100A。或者该内侧的流体储存膜内表面贴附于类似该耐热层24的耐热物,从而防止其内表面热封连接在一起。
该流体缓冲体10A被填充流体并形成该流体包装袋时,该定位缝38A的设置使该前侧壁10a’和该后侧壁10b’分别向内和分别向外形成凹凸结构。该前侧壁10a’和该后侧壁10b’的向内凹的倾向有利将包装物品保持于两个定位缝 38A之间,从而使该包装物品能够被更为牢固地包装,进而受到更好的保护。
在本发明的这个优选实施例中,各个该定位缝38A是塑封块,并呈圆形,本领域技术人员可以理解的是,该定位缝38A也可以是三角形,或者是其他形状如四边形、五边形、六边形等多边形,本发明在这方面并不受到限制。可以理解的是,因为该定位缝38A的设置,该流体缓冲体10A在填充流体并形成的该流体包装袋时,在内表面和外表面都形成凹凸结构,内表面形成的凹凸结构能够有效地对该包装物品起到固定作用而防止其遭受碰撞。该流体包装袋在其相反的前后侧壁10a’和10b’的外表面形成凹凸结构,这样,当多个该流体包装袋在一起堆放时,一个该流体包装袋的该流体缓冲体10A的内凹结构可以对应另一个该流体包装袋的该流体缓冲体10A的外凸结构,从而有效地节省空间,方便存放。
可以理解的是,在包装时,该流体包装袋的该流体缓冲体10A还没有填充流体,将该包装物品从该开口110A放入该容纳腔100A中。然后,将执行流体填充操作,这时流体进入该流体储存室14,从而该流体储存单元13A被填充有流体,从而向内凸出并按压作用于该包装物品的外表面,以形成与该包装物品的形状相适应的凹凸形状。也就是说,该流体包装袋被填充流体后的形状能够匹配被预先设置于该容纳腔100A内的包装物品的形状,从而能够被用于包装不同形状的包装物品,并且能够被用于包装不规则形状的物品。
根据该第二个优选实施例,本发明的该流体包装袋用于包装水果,例如可以是葡萄、苹果、梨、菠萝、桃、西瓜、橙子、桔子、李子、椰子、柚子、石榴、火龙果、芒果等等。可以理解的是,实施为水果的该包装物品只作为举例,而并不限制本发明。本发明的该流体包装袋还可以应用于包装其他食品如鸡蛋、鸭蛋、鹅蛋、咸蛋、皮蛋等蛋类食品,或者其他电子产品、灯具、陶瓷制品等等。
如图10和图11所示,该平面塑封缝30A进一步包括一系列塑形缝39A。该塑形缝39A被设置于该流体包装袋的底部,从而在该流体包装袋的底部连接两层流体储存膜11和12,从而防止该流体储存膜11和12中处于内侧的一层过度向内收缩,从而有利于保持该流体包装袋的整体造型。此外,该塑形缝39A的设置使该流体包装袋的底部更为平整,其更加适合站立,例如站立于一包装箱内。
根据本实用新型的该第二个优选实施例,该塑形缝39A为成对设置的月牙状。本领域技术人员能够理解的是,该塑形缝39A的上述形状仅仅是对本实用新型的示例而非限制。根据本实用新型的其它实施例,该塑形缝39A也可以是其它的形状,例如圆形、方形等。只要能够达到本实用新型的目的,本实用新型在这方面不做限制。
如图18-33所示为本发明的第二个优选实施例的变形实施例。该流体包装袋进一步具有至少一透气孔200B和至少一相对应的孔封缝201B,其中该透气孔200B把该容纳腔100A与该流体包装袋所处的外部环境连通起来,以使包装在 该容纳腔100A内的包装物能够通过该透气孔200B与外部环境相接触,以进行适度的呼吸活动。也就是说,当该流体包装袋用于包装生鲜产品如蔬菜和水果,环境的空气能够通过该透气孔200B提供给该生鲜产品如水果和蔬菜,使其能够进行适度的有氧呼吸,以防止其进行无氧呼吸而导致该蔬菜或者水果的腐烂,从而延长该生鲜产品如水果或者蔬菜的保鲜时间。值得一提的是,该孔封缝201B对应地设置于靠近该透气孔200B的边缘的部位,其将图中示意的两层流体储存膜塑封连接。在本发明的这个优选实施例中,该流体包装袋具有两个透气孔200B,其中该两个透气孔200B分别对称地设置于该流体包装袋的该前主侧壁101a和该后主侧壁101b上。具体地,该两个透气孔200B分别设置于该两个孔封缝201B的内部。本领域的技术人员可以理解的是,本发明的这个优选实施例的该透气孔200B和该孔封缝201B设置的位置仅作为举例,该透气孔200B和该孔封缝201B还可以实施为设置于该前主侧壁101a和该后主侧壁101b的其他合适位置,本发明在这个方面不作任何限制。孔封缝201可以用来在该流体缓冲体10C填充流体时,使其内部方便形成用来容纳生鲜产品的所述容纳腔101C,而其开口102C处可能因为所述流体包装袋的所述流体储存单元13A膨胀而封闭所述开口102C,但所述容纳腔101C可以通过所述透气孔200B与外部环境相连通,从而防止生鲜产品的无氧呼吸。
本领域的技术人员可以理解的是,该透气孔200B可以分别设置于该流体包装袋的该前主侧壁101a和该后主侧壁101b上,也可以设置于该流体包装袋的该前主侧壁101a上或者该后主侧壁101b上。也就是说,该透气孔200B可以分别设置于该流体包装袋的两侧,也可以只设置于该流体包装袋的一侧,本发明对此不作任何限制。
此外,在本发明的这个优选实施例中,该透气孔200B实施为圆形的形状。本领域的技术人员可以理解的是,该透气孔200B可以实施为其他任何的形状比如长方形,三角形,十字形等,也可以根据需要实施为不同的大小,本发明在这两个方面不做任何限制。
本领域的技术人员可以理解的是,该透气孔200B可以对称地设置于该前主侧壁101a和后主侧壁101b时。
值得一提的是,该流体包装袋还可以具有4个透气孔200B,如图22至图25所示;6个透气孔200B,如图26至图27所示;8个透气孔200B,如图28至31所示;以及21个透气孔200B,如图32至33所示,本发明对此不做任何限制。该透气孔200B根据需要可以实施为不同的形状、大小、数量以及排列方式,本发明在这几个方面均不作任何限制。
如图34-图37所示为本发明的流体包装袋的第三个优选实施例,其中该流体包装袋包括至少一流体缓冲体10C,即由一个该流体缓冲体10C形成一个立体包装袋或多个该流体缓冲体10C经塑封连接如粘接或热封形成该立体包装袋。在 本发明的图34至图37所示的示例中,其由一个该流体缓冲体10C形成。更具体地,参照图34和图35,该流体缓冲体10C包括至少两层流体储存膜11和12经一系列平面塑封缝30C和立体塑封缝40C形成包括一个或多个相连接的流体储存单元13C的该立体包装袋,各个该流体储存单元13C内形成一个可储存流体的流体储存室14C。
本领域技术人员可以理解的是,该平面塑封缝30C用于将多层薄膜经塑封形成如图34所示的一个平面缓冲材料,该立体塑封缝40C用于将上述平面缓冲材料进一步塑封而使该流体包装袋形成具有空间立体构型并且能够容纳该包装物品的该立体包装装置,如图29中所示。该平面塑封缝30C和该立体塑封缝40C可以通过粘接或热封连接的方式将多层薄膜连接在一起,优选地,在这个实施例中,该平面塑封缝30C和该立体塑封缝40C可以都实施为由热封工艺形成。
如图34中所示,该平面塑封缝30C进一步包括至少一分隔缝31C,在本发明的这个优选实施例中,该分隔缝31C实施为两列,分别设置在该流体缓冲提10C的两侧以成为该流体缓冲体10C的侧边界缝。也就是说,该分隔缝31C把该流体储存膜11和该流体储存膜12连接并封合在一起。该流体储存单元13C可以是各种形状,如条形,圆形,多边形或其他不规则形状等,本方明在这方面并不受到限制。在图34至图37所示的例子中,该流体包装袋包括一个该流体储存单元13,并且两侧的分隔缝31C形成侧边界缝,在两列该分隔缝31C之间形成该流体储存室14C。
如图34中所示,该平面塑封缝30C进一步地包括分别位于该流体缓冲体10C的顶侧和底侧的连续密封的一边封缝32C和顶侧邻近该边封缝32C的一连续密封的主通道密封缝33C,其中顶侧的该边封缝32C和该主通道密封缝33C之间形成该主通道151C。
可以理解的是,该边封缝32C通过塑封工艺如粘接或热封形成并且封合连接两层该流体储存膜11和12。该主通道密封缝33C通过塑封工艺如粘接或热封形成并且将两层该流体储存膜11和12和两层该阀膜21C和22C分别连接在一起。例如,通过一次热封工艺而形成的上下两侧的该主通道密封缝33C分别将该流体储存膜11和该阀膜21热封连接,以及将该流体储存膜12和该阀膜22热封连接,并且在除了对应该流体通道23C的其他位置将该阀膜21和22也一并热封连接。
如图34所示,该流体缓冲体10C包括一个该流体储存单元13C,并且沿纵向方向排列。该主通道单元15C沿横向方向排列并与该流体储存单元13C一体成形。值得一提的是,该流体包装袋可以具有一个或者多个该流体填充阀20C,在本发明的这个优选实施例中,该流体包装袋具有多个该流体填充阀20C,以形成多个流体填充通道,从而提高流体填充的速度和效率。在本发明的另一个实施例中,该流体包装袋还可以具有一个流体填充阀20C,本发明在这个方面不做任 何限制。
值得一提的是,当该流体包装袋实施为具有一个流体填充阀20C时,该流体可以依次通过该主通道151C和该流体填充阀20C进入该流体储存室14C中。在本发明的另一个实施例中,该流体包装袋可以实施为不具有该主通道151C,其中该流体缓冲材料直接通过该流体填充阀20C进入该流体储存室14C中。
如图34中所示的沿纵向延伸的该流体储存单元13C适合于被对折,从而得到如图35中所示的该储存单元13C的两个对折部相互相叠合的结构,从而该流体缓冲体10C形成前侧壁10a和后侧壁10b,然后通过左右两侧的该立体塑封缝40C将该流体缓冲体10C的左右两侧的前侧壁10a和后侧壁10b的边缘部分相连接,从而在该流体缓冲体10C填充流体后,该流体缓冲体10C形成具有开口102C的容纳腔101C,其中包装物品适合于通过该开口102C放入该容纳腔101C并储存在该容纳腔101C中。
在这个实施例中,该流体缓冲体10C被设置有两列该立体塑封缝40C,其中该立体塑封缝40C为连续的塑封,也就是说,该立体塑封缝40C将该前侧壁10a和该后侧壁10b的两侧密闭封合起来,如图34和图35所示。该立体塑封缝40C也可以是断续的塑封,也就是说该立体塑封缝40间断地连接该前侧壁10a和该后侧壁10b。
值得一提的是,当该立体塑封缝40C可以是额外独立的塑封缝,也可以是与该流体缓冲体10C左右两侧的分隔缝31C通过相同的热封工艺同时形成,或者可以说在平面塑封步骤中并没有形成该分隔缝31C,而在立体塑封步骤中形成该立体塑封缝40C,此时该立体塑封缝40C是连续的塑封,以实现该流体储存室的密封。
如图34至图37所示,该流体缓冲体10C还被设置有互相间隔地布置的多组孔封缝201C,并且在该流体缓冲体10C被对折而形成该前后侧壁10a和10b时,每组孔封缝201C的各个孔封缝201C位置相对应。也就是说,每组孔封缝201C包括塑封连接该前侧壁10a的该流体存储膜11和12的至少一个该孔封缝201C,以及塑封连接该后侧壁10b的该流体存储膜11和12的至少一个该孔封缝201C,并且两者形成在该流体包装袋的前后侧,并且位置互相对应。
如图34至图37中所示,在这个示例中,沿着纵向方向,该流体缓冲体10C设置有10个该孔封缝201C,其中,该孔封缝201C塑封连接该流体缓冲体10C的该流体储存膜11和12。在该流体缓冲体10C经立体塑封后,该流体缓冲体10C的前后两侧分别有5个该孔封缝201C,从而形成5组相对应的该孔封缝201C,使该流体缓冲体10C形成的该流体包装袋前后侧大致呈对称的结构。当该流体包装袋填充该流体缓冲材料时,这种对称设置的孔封缝201C能够把被包装物如苹果夹持在该对应的两个孔封缝201C之间,从而进一步防止该包装物在容纳腔101C内的移动,起到预定的定位作用。
在图34至图36的示例中,各个该孔封缝201C位于该流体储存单元13C的中部位置,各个该孔封缝201C的两侧分别形成有连通通路133C,相邻的两个该孔封缝201C之间形成流体缓冲段134C。也就是说,该孔封缝201C的形状和位置不影响该流体缓冲体10C形成整体相连通的该流体储存单元13C。也就是说,当该流体包装袋被填充流体缓冲材料时,该流体缓冲材料能够通过该联通通路133C充分填充该流体缓冲体10C,从而对被包装物品起到较为充分缓冲作用。
在本发明的这个优选实施例中,该孔封缝201C被实施为圆环的结构,即经过粘接或者热封方式形成环形密封缝,其中,该环形的孔封缝201C的内部无法填充该流体缓冲材料。值得一提的是,当该流体缓冲体10C填充该流体缓冲材料时,由于该环形孔封缝201C的四周的联通通路对应的该流体缓冲体10C部分由于被该流体缓冲材料填充而膨胀,从而把该包装物如苹果等支撑和分隔于各组孔封缝201C之间的空间内,从而进一步防止被包装物在该容纳腔101C内部的移动。
本领域技术人员可以理解的是,该孔封缝201C在这个实施例中实施为平面塑封缝,即在未进行立体塑封时即形成该孔封缝201C。而在另外的变形中,该孔封缝201C也可以在立体塑封步骤中进行,也就是说将该流体缓冲体10C对折以形成该前后侧壁10a和10b,然后通过塑封机形成该立体塑封缝40C和该孔封缝201C,在形成该孔封缝201C的过程中,如在热封工艺中,该容纳腔101C中设置有耐热阻隔装置,从而避免内侧的流体储存膜,如流体储存膜12C,在对折后其内表面被该孔封缝201C热封连接,即该孔封缝201C只热封连接该流体缓冲体10C的一侧的该两层该流体储存膜11和12,而不将四层膜热封连接成一体,从而保证连续贯通地形成该容纳腔101C。或者该内侧的流体储存膜11/12内表面贴附于类似该耐热层24C的耐热物,从而防止其内表面热封连接在一起。
在本发明的这个优选实施例中,各个该孔封缝201C是塑封块,并呈圆形,本领域技术人员可以理解的是,该孔封缝201C也可以是三角形,或者是其他形状如四边形、五边形、六边形等多边形,本发明在这方面并不受到限制。
如图35所示,该流体缓冲体10C经对折,该流体储存膜11C位于外侧,该流体储存膜12位于内侧以形成该容纳腔101C。更进一步地,如图37所示,当该流体缓冲体10C填充流体缓冲材料后,每组该孔封缝201C之间的位置附近形成一分装室1011C,而该流体缓冲段134C之间的位置附近形成一间隔空间1012C,即该容纳腔101C由该分装室1011C和该间隔空间1012C交替形成。当多个包装物品放入该容纳腔101C中并在该流体缓冲体10C内填充该流体缓冲材料时,该流体储存膜12C的内表面互相邻近并贴附于该包装物品,从而将该包装物品稳固地限位于该分装室中1011C。而因为该流体缓冲段134C内填充有流体,从而在其膨胀部分之间形成该间隔空间1012C,这样因为该膨胀的流体缓冲段134C的阻隔作用,一个该分装室1011C内的该包装物品将不容易越过该间隔 空间1012C而到达另一个该分装室1011C而造成对另一个该分装室1011C内的另一个包装物品的碰撞,从而得以防止多个该包装物品在该容纳腔101C中互相碰撞而造成损坏。可以理解的是该间隔空间1012C的宽度D小于该包装物品的厚度W,从而防止该包装物越过该间隔空间1012C而与相邻的该包装物发生碰撞,而导致包装物的损伤。
可以理解的是,相邻两组该定位缝38的部位大致与该包装物品的尺寸匹配,并且相邻两组该孔封缝201C之间的距离略大于该包装物品的尺寸,该流体包装袋底侧的该孔封缝201C和底侧的对折线之间的距离大致小于该包装物品的尺寸,从而在对应该孔封缝201C的位置附近形成该分装室1011C。在包装时,该流体包装袋的该流体缓冲体10C还没有填充流体,将多个该包装物品从该开口102C放入该容纳腔101C中后,对该流体包装袋填充该流体缓冲材料,这时该流体缓冲材料进入该流体储存室14C,从而使各个该流体缓冲段134C被填充该流体缓冲材料而膨胀凸出,以按压作用于各个对应的该包装物品的外表面,从而形成该间隔空间1012C使相邻的两个该包装物品相间隔。
如图34所示,该流体包装袋进一步具有至少一透气孔200C,其中该透气孔200C把该容纳腔100C与该流体包装袋所处的外部环境连通起来,以使包装在该容纳腔100C内的包装物能够通过该透气孔200C与外部环境相接触。也就是说,当该流体包装袋用于包装生鲜产品如蔬菜和水果时,外部环境中的空气能够通过该透气孔200C提供给该生鲜产品如水果和蔬菜,使其能够进行适度的有氧呼吸,以防止其进行无氧呼吸而导致该蔬菜或者水果的腐烂,从而延长该生鲜产品如水果或者蔬菜的保鲜时间。此外,由于该流体包装袋能够有效保鲜该生鲜产品,因此,生鲜产品在运输或者储藏时无需冷藏保鲜,因此大大节约了生鲜产品的运输和储存成本。
具体地,该透气孔200C设置于该流体缓冲体10上,以穿透该流体缓冲体10的该流体存储膜11和12,从而把该容纳腔100C与该外部环境连通起来。进一步地,其中该孔封缝201C设置于该透气孔200C的边缘部位,即该孔封缝201C内部形成该透气孔200C。值得一提的是,在本发明的这个优选实施例中,该流体包装袋具有十个透气孔200C,其中该十个透气孔200C分别对称地设置于该流体包装袋的该前主侧壁101a和该后主侧壁101b上。本领域的技术人员可以理解的是,本发明的这个优选实施例的该透气孔200C和该孔封缝201C设置的位置仅作为举例,该透气孔200C和该孔封缝201C还可以实施为设置于该前主侧壁101a和该后主侧壁101b的其他位置,本发明在这个方面不作任何限制。
本领域的技术人员可以理解的是,该透气孔200C可以分别设置于该流体包装袋的该前主侧壁101a和该后主侧壁101b上,也可以设置于该流体包装袋的该前主侧壁101a上或者该后主侧壁101b上。也就是说,该透气孔200C可以分别设置于该流体包装袋的两侧,也可以只设置于该流体包装袋的一侧,本发明对此 不作任何限制。
此外,在本发明的这个优选实施例中,该透气孔200C实施为圆形的形状。本领域的技术人员可以理解的是,该透气孔200C可以实施为其他任何的形状比如长方形,三角形,十字形等,也可以根据需要实施为不同的大小,本发明在这两个方面不做任何限制。

值得一提的是,根据需要,该流体包装袋还可以具有4个透气孔200C,6个透气孔200C,8个透气孔200C等,本发明对此不做任何限制,其中该透气孔200C对称地设置于该流体缓冲体10C的对应的两侧。值得一提的是,该透气孔200C根据需要可以实施为不同的形状、大小、数量以及排列方式,本发明在这几个方面均不作任何限制。

该流体包装袋进一步具有至少一透气孔200D,其中该透气孔200D把该容纳腔100D与该流体包装袋所处的外部环境连通起来,以使包装在该容纳100D内的包装物能够通过该透气孔200D与外部环境相接触。也就是说,当该流体包装袋用于包装生鲜产品如蔬菜和水果时,外部环境中的空气能够通过该透气孔200D提供给该生鲜产品如水果和蔬菜,使其能够进行适度的有氧呼吸,以防止其进行无氧呼吸而导致该蔬菜或者水果的腐烂,从而延长该生鲜产品如水果或者蔬菜的保鲜时间。此外,由于该流体包装袋能够有效保鲜该生鲜产品,因此,生鲜产品在运输或者储藏时无需冷藏保鲜,因此大大节约了生鲜产品的运输和储存成本。
具体地,该透气孔200C设置于该流体缓冲体10D上,以穿透该流体缓冲体10D的该流体存储膜11和12,从而把该容纳腔100D与该外部环境连通起来。进一步地,该流体包装袋进一步包括至少一孔封缝201D,该透气孔200D位于该孔封缝201D内。
