具体实施方式
虽然本发明以优选实施例作说明和描述，但是袋式容器可以许多不同的构型、尺寸、和材料来制造。
以下将参考附图，描述本发明的具有开口封闭件的袋式容器的示例性实施例。应当理解，在附图中各个部分的尺寸不按比例描绘，仅作示意说明，不代 表本发明产品的真实尺寸。
参看图1至图6，图中示出了根据本发明的第一优选实施例构造的袋式容器1。如图1A和图1B所示，袋式容器1包括容器本体10，该容器本体10具有带有开口的敞开顶部11并且具有尺寸设置成容纳一定体积的内容物的内部隔室。本实施例的容器本体10是一体化成型制造的，具有大致矩形的外部形状。在本实施例中，敞开顶部11被设计成稍微向内倾斜，以有助于组装时敞开顶部11的压紧装配。沿敞开顶部11的内表面的周向突出形成彼此平行的下部环状突起12和上部环状突起13。
袋式容器1还包括开口封闭件20和密封装置30。所述开口封闭件20与所述容器本体10的敞开顶部11连接，用于闭合所述敞开顶部11的开口。密封装置30被构造成安置在所述开口封闭件20内部并与所述敞开顶部11耦合。
图3和图4清楚地示出了开口封闭件20和密封装置30。如图所示，开口封闭件20大致上是一个具有敞开底部的盖体，包括盖板21和从盖板21向下延伸的侧壁22，所述侧壁22围绕限定接纳室23。侧壁22可包括从其底部边缘向内突出的加强肋(未示出)，所述加强肋在侧壁22的整个周长延伸，以抵接容器本体10的敞开顶部11。盖板21的中心设有通孔24。在开口封闭件20的侧壁22和敞开顶部11可以设置可联锁的紧固元件，以使二者更好地紧固锁合。例如，在开口封闭件20的侧壁22的内表面设置一或多个凹座(未示出)，在敞开顶部11的外表面上对应于所述凹座的位置设置一或多个突柱(未示出)，对应的所述凹座与所述突柱啮合。
如图2B和图5所示，整个密封装置30基本上可拆卸地容纳在开口封闭件20的接纳室23内。密封装置30包括顶壁31以及从所述顶壁31的下表面向下并稍微向外延伸的侧壁32，所述侧壁32围绕并限定一个自顶壁31向下稍微向外扩展的中空腔体33。稍微向外延伸的侧壁32与稍微向内倾斜的敞开顶部11的形状和尺寸相匹配，实现压紧装配。这种倾斜配置的好处是，敞开顶部11抵接密封装置30时可以进一步挤压密封装置30，从而加强二者之间啮合的紧密性。在密封装置30完全容纳在开口封闭件20的接纳室23后，开口封闭件20的侧壁22与密封装置30的侧壁32之间界定一空间(见图2B)，在装配时敞开顶部11被夹持在所述空间内，下文将作详细描述。
密封装置30还包括从所述顶壁31向上延伸的出口管34，所述出口管34 与所述容器本体的内部隔室保持连通。出口管34的尺寸做成刚好穿过开口封闭件20的通孔24并突出超过所述开口封闭件20。这样，密封装置30以出口管34为中心同轴可拆卸地配置在一起。沿侧壁32的外表面的周向突出形成彼此平行的下部环状凹槽35和上部环状凹槽36，所述下部环状凹槽35和上部环状凹槽36的定位、尺寸和形状被配置成分别与容器本体10的敞开顶部11的下部环状突起12和上部环状突起13相匹配，以实现彼此可紧密啮合。密封装置30的顶壁31设有凸缘37。
图6示出袋式容器1的立体分解图，如图所示，袋式容器1还包括封盖40，所述封盖40可拆卸地固定到突出超过开口封闭件20的出口管34。封盖40可卡接在出口管34上，或者通过螺纹与出口管34连接。在封盖40与出口管34之间可以设置密封圈41，以加强二者的密封连接。
使用时，把容器本体10的敞开顶部11套接在密封装置30的侧壁32上，其中敞开顶部11的下部环状突起12和上部环状突起13分别与密封装置30的侧壁32的下部环状凹槽35和上部环状凹槽36啮合，敞开顶部11的顶边缘靠接在密封装置30的凸缘37的下表面。然后，把套接在一起的容器本体10和密封装置30安置于开口封闭件20的接纳室23内，其中出口管34穿过开口封闭件20的通孔24并突出超过所述开口封闭件20，并且容器本体10的敞开顶部11被夹持在开口封闭件20的侧壁22与密封装置30的侧壁32之间所界定的空间内。具体地，在开口封闭件20的侧壁22的底部边缘上设置的加强肋向内压靠并抵接容器本体10的敞开顶部11，从而使敞开顶部11的下部环状突起12受压与密封装置30的下部环状凹槽35形成匹配的压紧啮合密封。替换地，敞开顶部11的下部中与开口封闭件20接触的那一部分的外径被设计成稍微大于相应的开口封闭件20的侧壁22的内径，以致于当二者耦合时所述敞开顶部11被开口封闭件20向内压靠并抵接密封装置30的侧壁32，从而使敞开顶部11的下部环状突起12受压与密封装置30的下部环状凹槽35形成匹配的压紧啮合密封。如图5所示，容器本体10的敞开顶部11沿整个周长都被密封装置30完全覆盖，所述容器本体10中的内容物不会漏出到容器外部，而容器外部的空气也不容易渗透进入容器内部，实现了优异的密封效果。
此外，密封装置30的凸缘37也向下压靠敞开顶部11的顶边缘，使得敞开顶部11的上部环状突起13与密封装置30的上部环状凹槽36也形成压紧密封。 在密封装置30与敞开顶部11的上部提供这样的压紧密封，不仅能进一步加强袋式容器1的密封效果，而且能使开口封闭件20、容器本体10和密封装置30之间的连接更牢固。
图7至10C所示为本发明第二实施例的袋式容器100。本实施例与第一实施例的结构基本相同，包括容器本体110、开口封闭件120、密封装置130和封盖140。
本实施例与上面描述的第一实施例主要的不同之处在于采用不同形式的密封机构。如图所示，容器本体110具有带有开口的敞开顶部111，所述敞开顶部111具有相对于所述袋式容器的纵轴线X向内水平延伸的上边缘112。在所述上边缘112的内端下表面设有向下延伸的环形齿113。所述敞开顶部111还包括在其下部内表面周向突出形成的支承部114、以及定位在上边缘112和支承部114之间的侧向环形齿115，所述支承部114、所述侧向环形齿115与所述上边缘112彼此平行。由敞开顶部111的侧壁内表面、上边缘112的下表面和侧向环形齿115界定凹口116。
本实施例中的密封装置130同样地被构造成安置在所述开口封闭件120内部并与所述敞开顶部111耦合。开口封闭件120大致上是一个具有敞开底部的呈倒T形盖体，包括盖板121和从盖板121向下延伸的侧壁122，所述侧壁122围绕限定接纳室123。侧壁122可包括从其底面向下突出的环形加强件125，当开口封闭件120被压向敞开顶部111时，所述环形加强件会发生弹性变形压合在敞开顶部111的上边缘112上。盖板121的中心设有通孔124。
密封装置130包括顶壁131、侧壁132以及将所述顶壁131与所述侧壁132连接的肩部137，其中所述侧壁132围绕并限定中空腔体133，所述肩部137包含面向上的环形槽135。在所述密封装置130的侧壁132上进一步设置面向外的侧向环形槽136。所述面向上的环形槽135和侧向环形槽136的定位、尺寸和形状被配置成分别与敞开顶部111的向下延伸的环形齿113和侧向环形齿115相匹配，以实现彼此可紧密啮合。密封装置130被构造成刚好卡接在敞开顶部111的支承部114与所述上边缘112之间。
如图9所示，密封装置130的顶部基本上可拆卸地容纳在开口封闭件120的接纳室123内，而侧壁132及其所限定的中空腔体133露出开口封闭件120的接纳室123之外。密封装置130还包括从所述顶壁131向上延伸的出口管134， 所述出口管134与所述容器本体的内部隔室保持连通。出口管134的尺寸做成刚好穿过开口封闭件120的通孔124并突出超过所述开口封闭件120。这样，密封装置130以出口管134为中心同轴可拆卸地配置在一起。密封装置30在其肩部137与侧壁132之间设有凸缘138。
封盖140可拆卸地固定到突出超过开口封闭件120的出口管134，包括上盖部141、套环142和手柄143。上盖部141的内部设有环形接纳部144，出口管134的上部管壁接合在所述环形接纳部144内。手柄143连接于上盖部141，方便使用者携带。套环142与上盖部141是分开的两个部件，套环142的内部设有内螺纹，与出口管134螺接，再将上盖部141卡接在出口管134上位于套环142之上的位置。套环142螺接到出口管134后，将向开口封闭件120施加向下的压力，使开口封闭件120压向敞开顶部111。设置在开口封闭件120的底面的环形加强件125因此受压发生弹性变形，压靠于所述敞开顶部111，以便在二者之间形成紧密密封。
使用时，把容器本体110的敞开顶部111套接在密封装置130的侧壁132上，其中敞开顶部111的向下延伸的环形齿113和侧向环形齿115分别定位在密封装置130的面向上的环形槽135和侧向环形槽136内并彼此啮合，密封装置130的凸缘138容纳在敞开顶部111的凹口116内。然后，把套接在一起的容器本体110和密封装置130安置于开口封闭件120的接纳室123内，其中出口管134穿过开口封闭件120的通孔124并突出超过所述开口封闭件120，并且容器本体10的敞开顶部111的上边缘112被水平地夹持在开口封闭件120的底面与密封装置130的肩部137之间。具体地，在开口封闭件120的底面上设置的环形加强件125在套环142与出口管134螺接后，受到向下的压力压靠并抵接敞开顶部111的上边缘112，从而使敞开顶部111的向下延伸的环形齿113受压与密封装置130的面向上的环形槽135形成匹配的压紧啮合密封。如图9所示，容器本体110的敞开顶部111沿整个周长都被密封装置130完全覆盖，所述容器本体110中的内容物不会漏出到容器外部，而容器外部的空气也不容易渗透进入容器内部，实现了优异的密封效果。
此外，敞开顶部111的侧向环形齿115也与密封装置130的侧向环形槽136形成啮合密封，这样不仅能进一步加强袋式容器100的密封效果，而且能使开口封闭件120、容器本体110和密封装置130之间的连接更牢固。
如上所述，本发明的要点之一在于，将袋式容器的三个组成部分：开口封闭件20，120、容器本体10，110和密封装置30，130设计成可彼此分离。通过提供互相匹配的可联锁紧固的元件，允许所述三个组成部分方便且简单地组装在一起，所提供的可联锁紧固的元件确保组装而成的容器保持密封闭合。
本发明的容器本体优选地是由柔性材料制成的柔性容器。柔性材料可以是包含硅胶或橡胶的材料，硅胶或橡胶是一种无毒性、耐高温、低温并且易于模制加工的聚合物材料。使用硅胶或橡胶制成的袋式柔性容器适合于食品的储存。特别优选地，实施例的容器本体由硅胶或橡胶模制而成。
本发明的开口封闭件和密封装置优选地由硬质塑胶材料制成。硬质塑胶材料可以是包含聚丙烯(PP，Polypropylene)的材料制成。聚丙烯是一种半结晶的热塑性塑胶，具备有耐酸碱、耐化学物质、耐碰撞及耐高温(-20℃～130℃)等优点。因其安全稳定的化学特性，聚丙烯不仅可以用来制作食品级容器，也可以放进微波炉中进行加热。进一步地，选用硬质塑胶材料有利于对容器本体的敞开顶部的夹固作用，保证了容器的密封效用。
此外，容器本体的高度和容积可以根据不同需求而改变，容器本体的壁厚可以取决于容器的容积而恰当地选择。当容积较大时，可以使容器壁具有较大的厚度，使得容器不会由于内容物的重量过大而破裂。
以上通过描述示例性实施例，详细说明了本发明的具有可拆卸的开口封闭件的袋式容器。应当理解，本发明的范围不限于上述实施例，而是由随附的权利要求所限定。在不背离本发明的目标和精神的情况下，能够对实施例进行各种修改，但是其仍然属于本发明的范围之内。
