具体实施方式
以下描述用于揭露本发明以使本领域技术人员能够实现本发明。以下描述中的优选实施例只作为举例,本领域技术人员可以想到其他显而易见的变型。在以下描述中界定的本发明的基本原理可以应用于其他实施方案、变形方案、改进方案、等同方案以及没有背离本发明的精神和范围的其他技术方案。
如图1至图5所示是根据本发明的优选实施例的具有空气缓冲性能的包装盒的示意图,其可以用于储存电子产品、食品、医药产品、化工原料、生物材料、 塑料陶瓷、快速消费品等各种待包装物品。因为所述包装盒具有空气缓冲性能,从而其适合用于为所述待包装物品提供空气缓冲的效果。
具体地,所述包装盒包括至少一可充气主体10,所述可充气主体10设置有至少一充气阀20,和一盒体30。所述可充气主体10安装于所述盒体30的内表面,以形成一体结构。所述充气阀20用于向所述可充气主体10内充气。所述可充气主体10用于给所述待包装物品提供空气缓冲作用。
也就是说,所述可充气主体10形成所述包装盒的内部结构,而所述盒体30形成所述包装盒的外部结构。在所述可充气主体10充气后,所述盒体30围绕于所述可充气主体10的外侧,从而容纳所述可充气主体10。
因此,所述包装盒可以使所述可充气主体10和所述盒体30一起运输到包装地,以用于对所述待包装物品的包装。所述可充气主体10在运输和储存过程中可以不充气,从而可以呈比如压缩的扁平形状,从而节省运输和储存所占用的空间。而在使用时,只需要将所述可充气主体10通过所述充气阀20充气并达到预定气压,所述可充气主体10的膨胀会自动带动所述盒体30成型,这样相对于传统包装技术,不需要再将充气垫塞入包装纸盒或包装纸箱中的步骤,大大节省了包装时间。
值得一提的是,在包装时,也可以将所述待包装物品放在所述包装盒中,然后向所述可充气主体10充气,这时所述可充气主体10膨胀并且围绕在所述待包装物品的周围,并且在膨胀过程中,可以自动调整位置,以使所述可充气主体10紧密围绕在所述待包装物品的周围,从而在充气完成后,所述待包装物品能够稳固地由所述可充气主体10将其保持在所述盒体30中。另外,在所述可充气主体10充气膨胀时,所述盒体30也同时对所述可充气主体10施加压力,从而所述压力能使所述可充气主体10更紧密地容纳在所述可充气主体10中,以形成紧凑结构。
所述可充气主体10可以通过各种安装方式安装在所述盒体30的内表面。例如通过胶水或其他粘接剂粘接在所述盒体的内表面,所述可充气主体10和所述盒体30之间的胶水可以沿着粘接线粘接,或者是一些局部位点的粘接,或者是 整块区域的粘接。本领域技术人员应当可以想到的是,其他安装方式也可以达到这样的效果,例如所述可充气主体10和所述盒体30的内表面分别设置有互相匹配的搭扣元件如维可牢(velcro)粘扣等。
优选地,在本发明的这个优选实施例中,所述可充气主体10和所述盒体30之间的通过胶水粘接在一起。并且所述可充气主体10和所述盒体30之间的粘力足够强,以在所述可充气主体10充气时,使所述可充气主体10不致于从所述盒体30上剥落下来。也就是说,所述可充气主体10和所述盒体30之间的粘力大于所述可充气主体10在充气时产生的所述可充气主体10和所述盒体30之间的拉扯力。
所述盒体30可以是通过各种传统材料制成,例如皮革材料,布质材料,纸质材料等。例如在本发明的这个优选实施例中,所述盒体30可以是纸盒(纸箱),其形状可以是长方形、正方形、多边型、异型纸盒、圆筒形等,其可以是单层结构,也可以是两层、三层、四层、五层或更多层的复合结构。例如所述盒体30可以包括内侧的里纸,中间的芯纸和外侧的面纸。所述里纸和面纸可以是茶板纸,牛皮纸等。所述芯纸可以是瓦楞纸等。其中所述瓦楞纸可以设置多层,从而能抵受搬运过程中的碰撞和摔跌。所述盒体30的纸质材料可以是硬性纸质材料制成,也可以是软性纸质材料制成,本发明的这方面也不受限制。
如图2和5中所示,根据本发明的这个优选实施例的具体例子,所述盒体30可以是三层结构,其包括作为里纸和面纸的两层牛皮纸301和中间的加强筋夹层302。牛皮纸301的材料比较轻并且软,中间的加强筋夹层302可以保持在所述两层牛皮纸301之间,以防止所述盒体30损坏。优选地,所述加强筋夹层32可以包括互相垂直地延伸的多条加强筋,例如包括多条横向加强筋3021和多条纵向加强筋3022。多条所述横向加强筋3021可以组成多组横向加强筋组,相邻的所述横向加强筋组之间可以具有预定距离,并且多组横向加强筋组可以附着在所述两层牛皮层301中的外层牛皮纸301上。类似地,多条所述纵向加强筋3022可以组成多组纵向加强筋组,相邻的所述纵向加强筋组之间可以具有预定距离,并且多组纵向加强筋组可以附着在所述两层牛皮层301中的内层牛皮纸301上。在这个实施例,所述加强筋夹层302可以是纱网结构,其可以包括互相垂直地延 伸的多条纱线。
所述盒体30可以是六面长方形结构,其具有一主体31,所述主体具有四个侧面,其可以通过设置在一个侧面的粘贴边311粘合在另一侧面内表面来形成中空结构。所述盒体30还包括两个端部32和33,如顶端部32和底端部33,这样所述盒体30在包装所述待包装物品时在其内部形成大致长方形的容纳空间34。两个所述端部32和33可以分别包括四个底封,其两两相对,用于卡合在一起。在这个优选实施例中,所述底端部33包括四个底封331,其两两相对,并且延伸于所述主体31,以用于互相叠合或卡合在一起,从而在所述盒体30用于包装所述待包装物品时,其底部开口是可以密封的,值得一提的是,在这个优选实施例中,四个底封331可以通过粘接剂粘合在一起。所述顶端部32形成顶端开口34,可以用于取放所述待包装物品,当然所述待包装物品也可以从其底部开口放入或取出。所述顶端部32包括两个可折叠部321,其可以沿着中间的折叠线322折叠,并且所述两个可折叠部321设置在相反的两侧,如左右两侧。所述顶端部32还包括两个封合部323,其设置在所述盒体30的另外相反两侧,如前后两侧。所述两个封合部323在按压时,互相靠近,并且可以通过粘接剂,粘合在一起,同时所述两个可折叠部321各自对折起来,这样所述两个封合部323和所述两个可折叠部321可以封合所述顶端开口34。值得一提的是,所述两个封合部323和所述两个可折叠部321可以一体地延伸于所述主体31。
在未使用时,所述可充气主体10未充气,所述盒体30的所述主体31可以处于压合状态,如其前后侧面可以互相靠近地贴合在一起,这样整个所述包装盒的体积非常小,呈压缩扁平形状,适合存储和运输。在对所述可充气主体10充气时,所述可充气主体10的膨胀使所述盒体30也自动成型。然后,再将所述待包装物品放入所述包装盒30中,或者也可以在未充气前,就将所述待包装物品放在所述包装盒中。然后,根据需要,将所述盒体30的两端的开口封合起来,这样整个包装过程完成。值得一提的是,所述盒体30也可以自封底结构,即充气后,其顶端部和底端部中至少有一端部可以自动封合其开口。另外,根据一些场合的需要,所述盒体30的底端部33可能在未充气前就预先封合起来,也就是说,所述盒体30可以没有底端开口,而只有所述顶端开口34。
值得一提的是,所述盒体30一般是规则的几何形状,其设置在所述可充气主体10周围后,多个所述包装盒在运输和储存过程中可以整齐地排放。也就是说,如果只使用所述可充气主体10来对所述待包装物品来进行包装,所述可充气主体10在充气后,并不一定形成规则的形状,所以在运输时不便于整齐地排列和放置。另外,所述盒体30不仅起到保护所述可充气主体10不受到坚硬物品的碰撞而导致损坏的作用,而且所述盒体30可以使包装更美观。所述盒体30外表面也可以设置有公司logo、艺术图案、文字广告等。
也就是说,本发明的所述包装盒,其所述可充气主体10与所述盒体30组合在一起,其结构上使得包装过程更省时方便,在所述可充气主体10充气时自动成型;所述可充气主体10与所述盒体30作为一个整体进行运输和存储,从而成本低廉;而且所述可充气主体10提供空气缓冲效果;所述盒体30起到保护所述可充气主体10并且向所述可充气主体10施加压力以稳固地维持所述可充气主体10于所述待包装物品上,并且所述盒体30起到增强所述包装盒的美观效果。这是单独的使用所述可充气主体10和所述盒体30用来包装都不能达到的效果。
所述可充气主体10可以附着在所述盒体30的内表面的局部位置,如某些侧面的内表面上,也可以是环绕地附着在所述盒体30的内表面,从而在充气后,所述可充气主体10在其中间形成容纳空间,以用于容纳所述待包装物品。
具体地,如图2至图4,以及图7至图11B所示,所述可充气主体10包括至少一充气单元11,其中所述充气单元11包括一第一气室层101和一第二气室层102,其相互重叠以形成一充气腔12并形成有至少一充气口13,所述充气口13与所述充气腔12相连通以用于向所述充气腔12充气。如图中所示,两个或多个充气单元11并排排列以形成所述可充气主体10,其中所述充气阀20设置于每个所述充气单元11。换句话说,各个所述充气单元11可以独立地充气,在相邻两所述充气单元11之间形成一延长的连接缝103,从而藉由这些连接缝103可以将所述充气腔12分成多个单独的充气腔12,这些连接缝103可以由热封工艺形成。这样在一个所述充气单元11被损坏而漏气时,其他的所述充气单元11可以不受影响。当然,值得一提的是,所述充气单元11也可以互相连通,这样只需要一个充气阀20,就可以对所有所述充气单元11充气。也就是说,本发明的 所述具有空气缓冲性能的包装盒可以通过所述第一气室层101和所述第二气室层102的热封形成多个所述充气单元11。
另外,因为每所述充气单元11的形状在充气后可以变化,从而所述可充气主体10可以制成各种形状和尺寸。所述充气单元11可以是条状(如横向条状和/或纵向条状等),块状等,其形状不受限制,在这个优选实施例中,所述充气单元11可以形成条状。在本优选实施例中,所述可充气主体10还可以形成一充气通路14,所述充气通路14与所述充气口13相连通,并且通过一个或多个所述充气阀20与每个充气单元11相连通,这样当从所述充气口13充气时,空气会进入所述充气通路14,然后所述充气通路14将空气导引进入对应的各个所述充气阀20,从而空气再进入到各个所述充气单元11中。也就是说,所述充气通路14是一空气分配通路,其将从充气口13中充入的空气分配到各个所述充气单元11。充气口13处可以设置有充气嘴,以连接到一充气设备如充气泵,从而为所述具有空气缓冲性能的包装盒填充空气。
所述可充气主体10的每个所述充气单元11分别具有多个分隔缝104,这样使每个所述充气单元11进一步形成多个对应的子充气单元111。值得一提的是,这些所述充气单元11的所述分隔缝104的位置对应,也就是说,所述可充气主体10具有多列互相间隔地设置的分隔缝104,设置在多个所述充气单元11的所述分隔缝104沿着直线排列,但是并不是连续的,从而相邻两列所述分隔缝104之间形成一个侧壁,从而使所述具有空气缓冲性能的包装盒形成了多个侧壁,这些侧壁包围出一容纳腔100,以用于容纳所述待包装物品。
各个所述充气单元11的所述分隔缝104的数量可以根据需要设置,也就是说,所述可充气主体10的多列所述分隔缝104的列数可以变化,从而对应的所述可充气主体10可以具有3、4或多个侧壁。如图2和图3所示,所述具有空气缓冲性能的包装盒可以形成有底壁,四周的周壁,以及顶壁。值得一提的是,这些分隔缝104可以由热封工艺形成。根据形成的侧壁的数目情况,其可以使所述容纳腔形成各种各样的容纳空间。
另外,这些分隔缝104没有将相邻的所述子充气单元111隔开,也就是说, 相邻的所述子充气单元111之间形成有至少一连通通道112,从而在充气时,空气通过这些连通通道112进入每个所述子充气单元111。在图中所示的实例中,相邻的所述子充气单元111之间的中心部位设置有热封形成的所述分隔缝104,所述分隔缝104的两侧形成有所述连通通道112。
在本发明的这个优选实施例中,所述具有空气缓冲性能的包装盒可以包括一个所述可充气主体10,其经过一系列热封工艺形成具有所述容纳腔的一个空气包装装置。在其他的实施例中,所述具有空气缓冲性能的包装盒可以由两个所述可充气主体10,三个所述可充气主体10或更多个所述可充气主体10构成,其首尾两端互相缝合在一起,从而形成具有所述容纳腔的包装装置,本发明在这方面不受限制。
在本发明的这个优选实施例中,所述可充气主体10形成一端封闭,另一端具有开口的空气包装袋。也就是说,其可以具有由所述充气单元11形成的四个周壁和一个底壁。在所述可充气主体10的顶部开口处,两相反侧如左右侧壁的多个所述子充气单元111可以分别设置有一个或多个密封缝105,多个密封缝105可以互相间隔地排列。所述密封缝105可以与对应的所述分隔缝104沿着互相平行地方向排列。各个所述密封缝105的尺寸可以小于对应的所述充气单元11的尺寸,从而对应的所述子充气单元111局部形成充气道114可充入气体,从而在其左右侧具有可折叠单元15。值得一提的是,本发明中定义的所述连接缝103,所述分隔缝104,所述密封缝105或其他热封缝的作用是将两层或多层薄膜通过热封工艺热封连接。
也就是说,因为靠近所述空气包装袋的所述顶部开口的位置的左侧和右侧的所述充气单元11中相对于前后侧,其只有局部充气,从而可以折叠起来,用于在包装完成后,前后侧面的所述充气单元11可以互相靠近,这样所述可充气主体10形成的所述空气包装袋的所述顶部开口可以封合起来。
所述充气单元11形成的各个所述子充气单元111可以沿着横向方向地排列在所述盒体30中,也可以沿着纵向的方向排列在所述盒体30中。一个或多个所述子充气单元111的外壁通过所述粘接剂40粘接在所述盒体30的内表面。例如, 所述可充气主体10形成的所述空气包装袋的前后侧或至少其中一侧的多个所述子充气单元111粘接在所述盒体30的内表面。或者,所述左右侧的多个所述子充气单元111粘接在所述盒体30的内表面。或者所述可充气主体10其首尾两端缝合线处,通过所述粘接剂40粘接在所述盒体30的内表面。
对于所述盒体30,当所述盒体30是大致长方形的结构时,其可以通过至少四个周壁之一的内表面与所述可充气主体10的外表面的某些部件粘接。例如,两者之间可以是点粘接,线粘接,或面粘接。也可以通过所述可充气主体10的某些未充气外边与所述盒体30的内表面粘接。也就是说,粘接的位置不受限制,所述盒体30和所述可充气主体10可以通过各种可以想到的方式粘接在一起。
如图6A和图6B所示是根据本发明的上述优选实施例的变形实施方式的包装盒,类似地,所述包装盒包括至少一可充气主体10a,和一盒体30a。所述可充气主体10a安装于所述盒体30a的内表面,以形成一体结构,所述可充气主体10a用于给所述待包装物品提供空气缓冲作用。
在本发明这个优选实施例中,所述盒体30a包括主体31a,其具有四个侧面,并且分成两组,两两相对。所述盒体30a具有顶部开口34a和底部开口35a。所述盒体30a在其两端分别具有封合结构36a,以用于分别封合所述顶部开口34a和所述底部开口35a。其中所述封合结构36a包括可枢转地延伸于所述主体31a的一侧如后侧的可折叠片361a和延伸于(如垂直地可枢转地延伸于)所述可折叠片361a的定位片362a,其中在封合开口时,所述定位片362a适合于叠合在所述主体31a的另一侧如前侧的内表面,从而所述可折叠片361a用于封合对应的开口。所述可折叠片361a和所述定位片362a连接处的中心位置可以形成有定位槽363a,所述主体31a的另一侧如前侧还一体地延伸有定位舌364a,所述定位舌364a适合于插入所述定位槽363a中,从而起到卡合定位的作用。
另外,所述封合结构36a也可以还包括分别延伸于所述可折叠片361a的侧翼365a,如图6A中所示,可以在封合时,贴在所述主体31a的左右两侧的内表面。
如图6B所示,所述可充气主体10a可以具有通过分割充气单元11a得到的 子充气单元111a而形成的四个周壁1001a和延伸于这四个周壁之间底壁1002a,以及一个可活动顶壁1003a。所述可活动顶壁1003a用于封合所述可充气主体10a的开口,所述开口用于取放待包装物品。
如图7至图10所示是根据本发明的第二个优选实施例的包装盒,其包括至少一可充气主体10和盒体40。所述可充气主体10安装于所述盒体40的内表面,以形成一体结构。充气阀20用于向所述可充气主体10内充气。所述可充气主体10用于给所述待包装物品提供空气缓冲作用.
所述盒体40可以是各种包装箱,如方形的纸质包装箱体,其包括至少一侧壳壁41。所述可充气主体10被安装于所述侧壳壁41内侧。如图9所示,值得一提的是所述侧壳壁41可折叠,从而使得所述盒体40可折叠。当所述可充气主体10充气时,空气从所述充气口13进入所述充气通道14。然后所述充气通道14将空气导引进入对应各个所述充气阀20,从而空气再进入到各个所述充气单元11中。也就是说,通过所述充气口13进入所述充气通道14的空气,被所述充气通道14分配到各个所述充气单元11。在空气进入各个所述充气单元11后,各个所述充气单元11开始展开。更具体地,所述充气单元11的所述子充气单元111首先展开。当所有子充气单元111完成展开后,整个所述充气单元11完成展开。当所有所述充气单元11完成展开后,所述可充气主体10的这些所述充气单元11包围出一容纳腔,以用于容纳所述待包装物品。在所述可充气主体充气的过程中,所述第一气室层101与所述第二气室层102之间的距离逐渐增加。同时,所述第一气室层101与所述102所受到的压力也逐渐增加。所述充气主体的所述充气单元11逐渐展开,从而所述可充气主体10也逐渐展开。当所述可充气主体10被充气展开所产生的压力大于所述盒体40的所述侧壳壁41维持其折叠状态所受到的力时,所述侧壳壁41开始展开。当所述可充气主体10完成展开时,所述侧壳壁41也完成展开,且所述侧壳壁41包围出一容纳空间,以供容纳所述可充气主体10。同时所述可充气主体10的所述可充气主体10展开后对所述盒体30的所述侧壳壁41施加的压力大于所述侧壳壁41维持其折叠状态的力,以维持所述侧壳壁41处于展开状态。值得一提的是,所述盒体40处于折叠状态时,所述可充气主体10也处于折叠状态,从而使得本发明具有空气缓冲装置的包装 盒在未使用之前的体积减少,以利于存储和运输,从而降低存储和运输成本。
值得一提的是,所述侧壳壁41进一步包括一组子侧壳壁411,各子侧壳壁411分别对应所述充气单元11的所述子充气单元111,从而根据所述充气单元11所形成的子充气单元111的数目情况,其可以使所述容纳腔形成各种各样的容纳空间,也可以使所述侧壳壁41通过所述子侧壳壁411的不同位置形成不同的形状。也就是说,所述可可充气主体10具有的侧壁分别与所述子侧壳壁411对应,根据可可充气主体10具有的侧壁数目,其可以使所述侧壳壁41通过所述子侧壳壁411形成不同的形状。
所述盒体40进一步包括一底壳壁42,所述底壳壁42的边缘与所述侧壳壁41连接,以供在所述侧壳壁41展开时形成所述容纳空间的一限位端,从而限定所述可充气主体10的位置。所述底壳壁42也提供支撑所述可充气主体10。在本优选实施例中,所述底壳壁42进一步包括一凸壳壁421和一凹壳壁422,所述凸壳壁421和所述凹壳壁422分别与面对面的两子侧壳壁411连接,并且可相对转动。所述凸壳壁421进一步包括一凸部4211和一连接部4212,所述连接部4212分别与所述子侧壳壁411和所述凸部4211连接。所述一凹壳壁422具有一缺口4221和两卡位部4222,所述卡位部4222分别位于所述缺口4221两侧。所述缺口4221对应所述凸部4211,以供凸部4211嵌入所述缺口4221,从而使得所述卡位部4222卡扣所述连接部4212。以这样一方式形成一卡扣结构,以限位及支撑所述可充气主体10。优选地,所述缺口4211的底部与所述凸部4211的底部结合于相邻接的子侧壳壁411的中轴线处,以增强限位和支撑效果。所述底壳壁42进一步包括一两翼壳壁423,两所述翼壳壁423分别设于与所述凸部4211相邻接的面对面的两子侧壳壁411。所述翼壳壁423进一步包括一限位部3241,以供限定所述凸壳壁4211的位置,以增加所形成卡扣结构的稳定性。形成所述卡扣结构时,首先转动所述凹壳壁422至与所述侧壳壁的底边缘平行的位置,然后分别转动两所述翼壳壁423,以使两所述翼壳壁423接触所述凹壳壁422。接着所述凹壳壁422的方向转动所述凸壳壁421,直至所述凸壳壁421的所述凸部4211嵌入所述凹壳壁422的所述缺口4221,以使所述凸壳壁421被限位,从而形成所述底壳壁42供限位及支撑所述可充气主体10。
所述盒体40进一步包括一顶壳壁43,所述顶壳壁43被设于所述侧壳壁41的顶部边缘,以供覆盖所述侧壳壁所包围形成的所述容纳空间。所述顶壳壁43可向所述底壳壁42方向转动。所述顶壳壁43进一步包括一顶部341,所述顶部可转动,以供当所顶壳壁覆盖所述容纳空间时,嵌入所述容纳空间,且与所述侧壳壁41接触以产生一压力阻止所述顶壳壁向上转动。所述盒体40进一步包括两限位壳壁44,分别设置所述顶壳壁43相邻的两侧,分别与相对应的两子侧壳壁411连接。两所述限位壳壁44可向所述容纳空间转动。当所述顶壳壁43覆盖所述容纳空间时,首先向所述容纳空间转动两所述限位壳壁44至与所述侧壳壁41顶部边缘平行的位置,然后向所述容纳空间转动所述顶壳壁43,并且使所述顶部341嵌入所述容纳空间与所述侧壳壁41接触。两所述限位壳壁44限制所述顶壳壁向所述容纳空间继续转动,从而保护所述可充气主体10。
值得一提的是,所述底壳壁42也可采用可折叠的自封底结构。采用自封底结构的底壳壁,在所述侧壳壁41展开时,随着所述侧壳壁展开时而展开。当所述侧壳壁41完成展开时,所述自封底结构的所述底壳壁也完成展开,可供限位所述可充气主体10以及支撑所述可充气主体10。如图11A和11B所示,例如其底部是可折叠的自封底结构。
在本发明一优选实施例中,未被充气的所述可充气主体10被固定于所述侧壳壁41的其中一子侧壳壁411。具体地说,未被充气的所述可充气主体10的所述可可充气主体10所具有的其中一侧壁被固定于所述侧壳壁41的其中一子侧壳壁411。也就是说,并列的充气单元11的其中一并列的子充气单元111被固定于所述侧壳壁41的至少一子侧壳壁411。优选地,所述子侧壳壁的宽度与所述子充气单元的宽度一致。所述固定所述可充气主体10的所述子侧壳壁411优选为与所述顶壳壁43连接的所述子侧壳壁411。可将与所述子侧壳壁411接触的一列并列的所述子充气单元111的其中一个子充气单元111的外表面固定于所述子侧壳壁411。也可以将该并列的所述子充气单元111的其中几个子充气单元111固定于所述子侧壳壁411。也可以将整列子充气单元111固定于所述子侧壳壁111。优选地为,将所述子充气单元111粘接至所述子侧壳壁411。
当所述可充气主体10进行充气时,若只有一列子充气单元111与所述子侧 壳壁411连接,则以与所述子充气单元111连接的所述子侧壳壁411为中心进行展开。当所述可充气主体10充气时,空气从所述充气口13进入所述充气通道14。然后所述充气通道14将空气导引进入对应各个所述充气阀20,从而空气再进入到各个所述充气单元11中。也就是说,通过所述充气口13进入所述充气通道14的空气,被所述充气通道14分配到各个所述充气单元11。在空气进入各个所述充气单元11后,各个所述充气单元11开始展开。更具体地,所述充气单元11的所述子充气单元111首先展开。值得注意的是,展开时以与所述子侧壳壁411连接的所述子充气单元111为中心进行展开。所述可充气主体10在展开的过程中,向所述分别向子侧壳壁411施加压力,以推动所述子侧壳壁411展开,从而使得所述侧壳壁41向外展开,以形成所述容纳空间供容纳所述可充气主体10。在所述侧壳壁41向外展开时,也带动具有自封底结构的所述底壳壁42进行展开。当所述侧壳壁41展开完毕时,所述底壳壁42也展开完毕,以供限位和支撑所述可充气主体10。当所有子充气单元111完成展开后,整个所述充气单元11完成展开。当所有所述充气单元11完成展开后,所述可充气主体10的这些所述充气单元11包围出一容纳腔,以用于容纳所述待包装物品。在所述空气缓冲装置充气的过程中,所述第一气室层101与所述第二气室层102之间的距离逐渐增加。同时,所述第一气室层101与所述102所受到的压力也逐渐增加。所述充气主体的所述充气单元11逐渐展开,从而带动所述可充气主体10也逐渐展开。当所述可充气主体10展开所产生的压力大所述盒体40的所述侧壳壁41维持其折叠状态所受到的力时,所述充气主体推动所述侧壳壁41开始展开,且支撑所述侧壳壁41。当所述可充气主体10完成展开时,所述侧壳壁41也完成展开。
在本发明一优选实施例中,所述侧壳壁41被推动时,所述侧壳壁41的所述子侧壳壁411相邻的两子侧壳壁411向同一方向转动,以撑开所述侧壳壁41,从而使得所述侧壳壁41围绕形成所述容纳腔。
值得一提的是,所述可充气主体10的各侧壁可被固定在相应的所述侧壳壁41的所述子侧壳壁411。所述盒体40内可供设置一个或多个可充气主体10。
值得一提的是,可将多个所述可充气主体10可分别设置在所述盒体40的所述侧壁41内侧,所述带有自封底结构的所述底壁42和所述顶壁43,以供在所 述盒体40被撑开后,由多个所述可充气主体10形成所述容纳腔。
如图11C至图11G所示,根据另外的一种变形实施方式,所述包装盒包括至少一可充气主体10以及一盒体50。所述盒体50可以实施为纸箱,其包括相连接的多个侧壁51,顶壳壁52和底壳壁53,其在撑开时形成大致方形的容纳空间。在这个实施例中,所述盒体50两端都可以封合起来。并且在这个实施例中,另提供了一种底部自封部结构。
如图中所示,所述底壳壁53包括适合于扣合的两个扣合壁531,其分别具有缺口533,和两相对的封合壁532,在叠合时,通过所述缺口533,使两个所述扣合壁531互相扣合,并且两个所述封合壁532与对应的两个所述扣合壁531至少部分地叠合,从而封合所述盒体的底部。
如图11H至图11I所示,根据另外的变形实施方式,上述可充气主体10形成的包装袋,其角落形成的折叠部15适合于通过端缝106与所述包装袋的侧壁封合在一起,所述端封缝106可以实施为连续或断续的热封线。设置所述折叠部15的方式可以使所述包装袋形成大致方形的用于容纳包装物品的容纳腔。
如图12A至图12C所示,根据本发明的另外的变形实施方式,所述包装盒包括至少一可充气主体10以及一盒体60。在这个变形实施例中,所述盒体60可以是软质牛皮纸袋,其包括互相叠合的两个侧壳壁61和分别连接于两个所述侧壳壁61的叠合壁63。所述叠合壁63提供折叠线631,从而在所述可充气主体10未充气时,可以沿着所述折叠线631将所述盒体60折叠。
另外,两个所述侧壳壁611的底端部611可以通过类似粘接剂的方式粘接在在一起,而不像上面实施例中通过几个底壳壁来扣合或叠合。另外,所述盒体60也可以进一步地包括封合端部62,其适合于套置在所述盒体60的所述侧壳壁611的底端部611,并且可以采用类似粘接的方式与所述底端部611相粘接,从而保证所述盒体60底部的封合状态。
如图12D至图12F所示,根据本发明的另外的变形实施方式,所述包装盒包括至少一可充气主体10和一盒体70。所述盒体70可以是一个标准纸箱,其顶 部和底部都可以采用四个顶或底壳壁71进行叠合来封合其顶端和底端。在这个实施例中,所述可充气主体10形成充气袋,并且进一步地具有顶侧充气壁10t,在充气后,所述顶侧充气壁10t适合于叠合于包装物品上,并且进一步地被所述盒体70的顶壳壁71压合,从而给包装物品提供多侧面的缓冲效果。
如图13和图14所示,是另外一种可充气主体10b,其也可以附着本发明的所述包装盒的盒体30的内部。所述可充气主体10b在两外侧的多个所述充气单元11b分别形成有未充气部分,从而在所述具有空气缓冲性能的包装盒充气后,可以在其角落处形成未充气翼15b。所述未充气翼15b可以塞入所述具有空气缓冲性能的包装盒的所述容纳腔中。所述未充气翼15b也形成有容纳空间,其可以用来容纳并连接于所述盒体30b的底角。另外,所述可充气主体10b的顶侧,如图6D所示,具有四个侧面,其具有面对面设置的充气单元11b以及面对面设置的未充气部16b。因为设置有所述未充气部16b,所以设置有所述充气单元11b的另外两侧面可以向下折叠,从而封合所述具有空气缓冲性能的包装盒的开口。值得一提的是,可以意识到的是,本发明的对应所述未充气翼15b和所述未充气部16b也可以替换成由具有多个小直径气室的小气室部组成,这样也使所述具有空气缓冲性能的包装盒的局部具有一定的可折叠性。
也就是说,如果所述未充气翼15b和所述未充气部16b的各个所述子充气单元111b两侧的所述分隔缝104b的尺寸够大,能够完全密封对应的所述子充气单元111b,而成为一个未充气单元。值得一提的是,这样在包装完成后,所述未充气部16b形成的未充气单元向内折叠,前后侧壁互相靠近,就可以封合所述可充气主体10b形成的所述空气包装袋的顶部开口。
如图15和图16所示是另外的可充气主体10c和10d的实施方式,其也可以安装在本发明的所述包装盒的所述盒体10的内部,其包括四个周壁和底壁,图15中可充气主体10c具有用于封合开口的可活动顶壁,而图16中可以不设置所述用于封合开口的可活动顶壁。
如图17所示是另外的可充气主体10e的实施方式,其也可以安装在本发明的所述包装盒的所述盒体30的内部。在这个变形实施方式中,所述可充气主体 10e的首尾两端封合在一起,从而适合于环绕在所述待包装物品的周围,从而所述可充气主体10e可以形成一个物品周缘包装装置。
也就是说,这个变形实施方式中所述可充气主体10e可以没有顶壁和底壁,而只是包围所述待包装物品的周边。所述可充气主体10e的充气单元11e可以具有大直径气室和小直径气室,其中大小直径气室可以交替排列。例如在本变形实施方式中,小直径气室设置在中间,大直径气室设置在两侧,从而所述待包装物品适合于卡合在所述可充气主体10e的接近中间的位置,而大直径气室起到收紧两边的开口的作用,以防止所述待包装物品滑出。
另外,值得一提的是,大小直径气室可以通过如下方法得到,即其中大直径气室可以设置有两个或多个充气阀20e,小直径气室可以只设置有一个充气阀20e。当然大小直径气室也可以只设置一个充气阀20e,但其宽度和尺寸有区别。
如图18至图20所示是另外的可充气主体10f的实施方式,其中当分隔所述充气单元11f而得到子充气单元111f时,在邻近所述可充气主体10f的开口处的相邻两个子充气单元111f其中之一设置有多个互相间隔的分隔缝104f,这样在充气后,相邻所述子充气单元111f形成一个所述子充气单元的一端部压合在另一个所述子充气单元的一端部,如图20所示,从而起到收紧开口的作用。
值得一提的是,当所述可充气主体10f安装在所述包装盒的所述盒体30内时并且充气时,所述盒体30向邻近所述可充气主体10f的开口处的这些子充气单元111f施加压力,从而更容易使相邻所述子充气单元111f中一个所述子充气单元的一端部压合在另一个所述子充气单元的一端部,以收紧开口从而防止所述待包装物品滑出所述包装盒。
如图21所示是另外的可充气主体10g的实施方式,所述可充气主体10g在热封时,在两端可以将多个气室111g形成侧压气室。并且外侧气室可以设置热封106g,从而两侧气室不充气,从而所述可充气主体10g可以容纳不同规则的所述待包装物品。
如图22和图23所示,所述包装盒可以包括两个所述可充气主体10h,其互 相粘合在一起,在这个实施例中,一个所述可充气主体10h的充气单元11h正好面对着另一个所述可充气主体10h的连接缝103h的位置。也就是说,两个所述可充气主体10h的充气单元11h可以错开地布置,这样缓冲作用得到加强。也就是说,内层的所述可充气主体10h因为所述连接缝103h而形成内凹结构时,通过外层的另外一个所述可充气主体10h的充气单元11h的补强作用,从而加强了空气缓冲效果。
值得一提的是,这种结构也可以提供保温效果,即两层的结构,通过错开的空气柱,使得外界不容易通过连接缝103h处进行热传导,从而有效地防止所述可充气主体10h内外的热量交换。
如图24至图26所示,所述包装盒也可以适合于包装延长形物品如红酒或灯具等。相应地,所述可充气主体10i设置在盒体30内,并且被充气后形成延长形容纳腔100i,从而延长形物品适合于存储在所述容纳腔100i内。
如图27所示,所述可充气主体10j在充气后也可以形成多个容纳腔100j,从而适合于容纳多个待包装物品。如图28所示,所述可充气主体10k可以是多层气室结构,例如可以由内层充气主体和外层充气主体形成双层充气叠合结构。在图29所示的例子,所述可充气主体10l内层充气主体和外层充气主体的气室11l之间也可以形成错位叠层结构,从而减小厚度又增强空气缓冲性能。
值得一提的是图1至图29列举了各种所述可充气主体10的变形实施方式,在实际应用中,还可能有其他的变形结构,其只要能在所述包装盒内部起到提供空气缓冲作用即可。
另外,所述充气阀20可以是由两层或多层薄膜形成,也可以是其他结构的充气阀,如机械阀,其可以设置于所述可充气主体10,也可能进一步地固定于所述盒体30。
如图30所示,所述充气阀20是单向阀,其包括两密封膜21和22,其互相重叠的固定在所述两气室层101和102之间,从而形成四层结构,所述两密封膜21和22之间形成一个充气通道24。相应地,当所述可充气主体10充气后,所 述两密封膜21,22粘合在一起以将所述气袋所述充气通道密封,从而将空气密封于所述气袋10的所述充气腔12内,在所述可充气主体10包括多个充气单元11时,多个充气阀20对应地设置在各个所述充气单元11中以分别将空气密封在各个充气单元11内。特别地,所述第一密封膜21重叠地粘合于所述第一气室层101,所述第二密封膜22重叠地粘合于所述第二气室层102。在向所述可充气主体10充气时,空气被导引进入所述第一密封膜21和所述第二密封膜22之间形成的所述充气通道24。当所述可充气主体充满气后,所述第一密封膜21和所述第二密封膜22互相粘合从而密封所述可充气主体的所述充气通道24。另外,所述可充气主体内的气压作用于所述两密封膜21和22,从而保证所述两密封膜21和22紧密粘合在一起,以防止空气从所述气阀20泄露出去。也就是说,所述气阀为一单向阀,其只允许气体进入所述可充气主体10而防止气体反渗出去。
所述充气阀20的所述充气通道24的形成可以在所述两密封膜21和22之间设置阻隔装置来实现,当将所述两密封膜21和22与所述两气室层101和102热封时,因为所述阻隔装置的设置,所述两密封膜21和22不会完全热封在一起,从而形成所述充气通道24。在一个具体的例子中,所述阻隔装置可以是耐高温的油墨。
如图31至图33B所示,是根据本发明的另外一种实施方式的空气包装置,其主要示意了另外一种充气阀20A的结构,所述充气阀20A为双止回阀,以给所述可充气主体提供双重密封效果。其中所述充气阀20A包括一第一密封膜21A,一第二密封膜22A和一止回密封膜23A。
所述第一密封膜21A和所述第二密封膜22A重叠在所述充气单元11A的所述第一气室层101A和所述第二气室层102A之间。所述第一密封膜21A和所述第二密封膜22A为相互重叠的由塑料制成的两薄层柔性膜。优选地,所述第一密封膜21A和所述第二密封膜22A为相同的两层膜。
每所述第一密封膜21A和所述第二密封膜22A具有一近边缘,其延伸于所述充气单元11A的所述充气阀20A的入口,和一远边缘,其延伸至所述充气单元内部。优选地,所述第一密封膜21A和所述第二密封膜22A的近边缘和远边 缘的边界各自毗连。
在本实施例中,所述第一密封膜21A的近边缘与所述第一气室层101A相粘合。所述第二密封膜22A的近边缘与所述第二气室层102A相粘合。
所述止回密封膜23A重叠于所述第一密封膜21A和所述第二密封膜22A的近端,以在所述第一密封膜21A和所述止回密封膜23A之间形成一充气通道24A,并在所述止回密封膜23A和所述第二密封膜22A之间形成一止回通道25A。
所述充气通道24A被排列成用于向所述充气腔12A充入空气以填充所述充气单元11A,直至通过所述充气腔12A内的气压,使所述第一密封膜21A和所述第二密封膜22A的远端重叠并密封以关闭所述充气通道24A。根据本优选实施例,当有气体从所述第一密封膜21A和所述第二密封膜22A的远端之间有空气泄露时,如图33A和33B所示,所述充气腔内12的空气被导引进入所述止回通道25A,以产生补充气压,从而进一步密封所述充气通道24A,以补偿所述第一密封膜21A和所述第二密封膜22A的密封效果的不足。
所述充气通道24A具有两开放端,其中之一近开放端形成于所述第一密封膜21A和所述止回密封膜23A的近边缘。另外之一远开放端延伸至所述第一密封膜21A和所述第二密封膜22A的远边缘,以与所述充气腔12A相连通。压缩空气可以通过所述充气通道24A导引进入所述充气腔12A。
值得一提的是,当所述充气单元11A充满空气后,所述充气腔12A内的气压向所述第一密封膜21A和所述第二密封膜22A施加压力,从而密封所述第一密封膜21A和所述第二密封膜22A远边缘,并且密封所述充气通道24A的远开放端。另外,所述第一密封膜21A和所述第二密封膜22A的远端因为表面张力而密封在一起。
所述止回密封膜23A为由塑料制成的薄层柔性膜。优选地,所述止回密封膜23A,所述第一密封膜21A和所述第二密封膜22A为聚乙烯(PE)膜。另外,每所述第一气室层101A和所述第二气室层102A的厚度大于每所述第一密封膜21A,所述第二密封膜22A和所述止回密封膜23A的厚度。
根据本发明的优选实施例,所述止回密封膜23A的长度小于每所述第一密封膜21A和所述第二密封膜22A的长度,从而当所述止回密封膜23A重叠于所述第一密封膜21A和所述第二密封膜22A的近端时,所述第一密封膜21A和所述第二密封膜22A的远端重叠在一起。值得一提的是,所述止回密封膜23A的长度定义为所述止回密封膜23A的近边缘和远边缘之间的距离。每所述第一密封膜21A和所述第二密封膜22A的长度定义为所述第一密封膜21A和所述第二密封膜22A的近边缘与远边缘之间的距离。
相应地,所述第一密封膜21A和所述第二密封膜22A的近边缘和所述止回密封膜23A的近边缘处毗连。另外,所述止回密封膜23A的近边缘与所述第二密封膜22A的近边缘相粘合。
所述止回通道25A形成于所述止回密封膜23A与所述第二密封膜22A之间,其中所述止回通道25A具有一开放端面向所述充气腔12A和一封闭端面向气阀开口。换句话说,所述止回通道25A的近端为所述封闭端而所述止回通道25A的远端为所述开放端。
相应地,当空气在所述开放端充入所述止回通道25A时,所述止回通道25A充入空气以产生补充气压,从而进一步密封所述第一密封膜21A和所述第二密封膜22A之间的所述充气通道24A。
值得一提的是,当通过所述充气通道24A向所述充气腔12A充气时,所述充气通道24A内的空气流向与所述止回通道25A的空气流向相反。因此,空气不会充入所述止回通道25A。当空气从所述充气腔12A泄露回所述止回通道25A时,空气进入所述止回通道25A以产生补充气压进一步密封所述充气通道24A,从而防止漏气。值得一提的是,泄露的空气在从所述充气通道24A的近开放端泄露前,会从所述充气通道24A的远开放端流向所述止回通道25A的远开放端,从而避免空气泄露。另外,所述止回密封膜23A与所述第一密封膜21A由于表面张力密封在一起以密封所述充气通道24A。
为了在所述充气单元11A形成所述充气阀20A,所述充气阀20A还包括一第一密封接合处201以在所述充气单元11A的气阀开口处将所述第一气室层101A 与所述第一密封膜21A粘合在一起,和一第二密封接合处202以在所述充气单元11A的气阀开口处将所述第二气室层102A,所述止回密封膜23A和所述第二密封膜22A粘合在一起。
相应地,所述第一密封膜21A的近边缘通过所述第一密封接合处201与所述第一气室层101A粘合。所述第二气室层102A与所述第二密封膜22A的近边缘,所述止回密封膜23A的近边缘通过所述第二密封接合处202A粘合在一起。优选地,两互相间隔的密封接合处201A用来将所述第一气室层101A和所述第一密封膜21A粘合,两互相间隔的第二密封接合处202A用来将所述第二气室层102A,所述止回密封膜23A和所述第二密封膜22A。值得一提的是,所述第一密封接合处201A和所述第二密封接合处202A可以为热封线,也可以是其他形状如月牙形状的热封。换句话说,所述第一密封膜21A的近边缘与所述第一气室层101A通过所述密封接合处201A热封在一起。所述第二气室层102A与所述第二密封膜22A的近边缘,和所述止回密封膜22的近边缘通过所述第二密封接合处202A热封在一起。
为了保持在所述热封过程后,所述第一密封膜21A和所述止回密封膜23A之间存有空间,所述充气阀20A还包括一第一耐热物26A,其形成于所述第一密封膜21A和所述止回密封膜23A之间以保证所述充气通道24A的形成。所述第一耐热物26A用于防止所述第一密封膜21A和所述止回密封膜23A在所述热封过程后完全粘贴在一起。
具体地,所述第一耐热物26A设置在所述第一密封膜21A和所述止回密封膜23A的近边缘部并位于所述充气单元11A的气阀开口处,从而保证所述充气通道24A的所述近端处于打开状态。
同样的,为了保持在所述热封过程后,所述第二密封膜22A和所述止回密封膜23A之间存有空间,所述充气阀20A还包括一第二耐热物27A,其形成于所述第二密封膜22A和所述止回密封膜23A之间以保证所述止回通道25A的形成。
具体地,所述第二耐热物27A设置在所述第二密封膜22A和所述止回密封膜23A的远边缘部,从而保证所述止回通道25A的所述远端处于打开状态。值 得一提的是,所述止回通道25A的近端被所述第二密封接合处202封闭。
根据本优选实施例,所述第一耐热物26A和所述第二耐热物27A为两耐热层,其涂覆在各自对应的膜上的预定位置,以防止在所述垫封过程中膜粘贴在一起。所述第一耐热物26A延伸于所述止回密封膜23A近端一侧,并朝向所述第一密封膜21A。所述第二耐热物27A延伸于所述止回密封膜23A的远端位于相反一侧,并朝向所述第二密封膜22A,其中所述第二耐热物27A没有设置在所述止回密封膜23A的近端的相反一侧,这样所述止回通道25A的所述近端可以被所述第二密封接合处202A封闭。值得一提的是,所述第二耐热物27A不仅避免所述止回密封膜23A与所述第二密封膜22A粘合在一起,以保证所述止回通道25A的所述远端处于打开状态,而且加强所述止回密封膜23A与所述第一密封膜21A之间的作用,从而由于表面张力以封闭所述充气通道24A。
所述充气阀20A还包括两侧向密封接合处203A,其为两第三密封接合处以将粘合所述第一密封膜21A和所述止回密封膜23A,从而形成所述充气通道24A的侧壁。所述充气通道24A的宽度由所述两侧向密封接合处203A界定。具体地,所述两侧向密封接合处203A为两倾斜热封线,从而所述充气通道24A的宽度从所述气阀开口各所述充气腔递减。换句话说,所述充气通道24A的近开放端为一较大的开放端其与所述气阀开口相连通,而所述充气通道24A的远开放端为一锥形开放端并与所述充气腔12A连通。所述锥形的充气通道24A进一步避免空气从所述充气腔12A泄露到所述气阀开口。
优选地,所述侧向密封接合处203A从所述第一密封膜21A和所述第二密封膜22A的近边缘延伸至其远边缘。因此,所述侧向密封接合处203A位于所述第一密封膜21A和所述第二密封膜22A近端部分与所述止回密封膜23A粘合在一起。所述侧向密封接合处203A位于所述第一密封膜21A和所述第二密封膜22A远端部分与所述第一密封膜21A和所述第二密封膜22A粘合在一起。
相应地,为了向所述充气单元11A充气,泵的插脚插入到所述充气口13A以将压缩空气充入所述充气通道24A,其中空气的充气方向为从所述充气通道24A的近开放端到达远开放端。这样所述充气单元11A开始充气。所述充气腔 12A的气压增大从而撑开所述第一气室层101A和所述第二气室层102A。同时,气压作用于所述第一密封膜21A和所述第二密封膜22A,特别是作用于所述第一密封膜21A和所述第二密封膜22A的远端。当所述充气单元11A完全填充空气后,即到达最大填充量后,所述充气腔12A内的气压达到足够以密封所述第一密封膜21A和所述第二密封膜22A的远端,以自动密封所述充气通道24A的所述远开放端。这时泵的插脚抽离所述充气口13A。
当所述第一密封膜21A和所述第二密封膜22A的远端没有完全封合在一起时,所述充气腔12A的空气可能会泄露到所述充气通道24A。为了避免空气泄露到所述充气通道24A,所述止回密封膜23A与所述第一密封膜21A封合以将所述充气通道24A的远开放端密封。具体地,所述止回通道25A的进气方向与所述充气通道24A的充气方向相反。另外,当所述止回通道25A的所述开放端打开时,所述充气通道24A的所述远开放端关闭。因此,空气从所述止回通道25A的所述开放端进入并保留在所述止回通道25A内。
所述止回通道25A由空气填充,这样所述止回通道25A内产生补充气压以进一步密封所述充气通道24A。特别地,所述第一密封膜21A和所述止回密封膜23A之间的所述充气通道24A的所述远开放端被密封。更具体地,所述止回通道25A内的补充气压越高,所述止回密封膜23A的密封效果越好。换句话说,当空气从所述充气腔12A泄露以降低所述充气腔12A的气压时,空气进入所述止回通道25A以提高所述止回通道25A的气压。因此,所述充气压的总气压,即所述充气腔12A和所述止回通道25A的气压之和保持不变。这样,从所述充气腔12A进入所述止回通道25A的空气会进入加强所述充气通道24A的密封效果。
本领域的技术人员应理解,上述描述及附图中所示的本发明的实施例只作为举例而并不限制本发明。本发明的目的已经完整并有效地实现。本发明的功能及结构原理已在实施例中展示和说明,在没有背离所述原理下,本发明的实施方式可以有任何变形或修改。
