用于广口的塑料吹塑容器的多功能底部
技术领域
本发明涉及用于广口的吹塑塑料容器的一底部，更具体地说，本发明涉及使容器能用在热灌装以及加热杀菌/蒸馏处理中的多功能底部。
背景技术
已经在热灌装应用中采用了塑料吹塑制成的容器、尤其是那些用PET吹塑成的容器，在热灌装中，容器被灌装加热到超过180°F(82℃)的温度的液体产品，并在灌装后立即封盖，并使其冷却到室温。在加热杀菌/蒸馏处理中也采用了塑料吹塑容器，在加热杀菌/蒸馏处理中，灌装和密封好的容器经受加热处理，然后冷却到室温。在这两种情况下，容器通常设有真空吸收板，以在密封容器的内容物加热和/或在密封容器内的内容物冷却时适应容器中的容积的变化。

同样转让给Graham Packaging Company，LP.的待审批国际申请第PCT/US00/31834号揭示了一种具有一新型底部的可进行加热杀菌的广口容器。

尽管上述的容器和底部结构对于它们的设计目的可以令人满意地工作，但是人们需要一种广口的塑料吹塑容器，它尤为适合于包装各种各样的粘稠液体和其它食品，并且具有一能使容器可用于热灌装和加热杀菌处理的新型的底部结构。底部结构应能适应在加热杀菌的过程中所经受的增加的内部压力，能适应在冷却过程中在密封容器中所形成的真空，能防止不希望的倒置或类似的变形，并能与类似的容器有效地叠置。
发明内容
针对前面的叙述，本发明的一个主要目的是提供一种商业上令人满意的广口吹塑容器，它能被应用于包装流质、粘稠的及固体食品的热灌装以及加热杀菌或蒸馏中。
本发明的另一个目的是提供一种底部结构，它能在密封容器承受热处理时适应容器内部压力的上升，并能在冷却的过程中适应真空。
本发明的另一个目的是提供一种可热灌装和可加热杀菌的容器，它具有可适应内部压力和容积变化并防止不希望的倒置和其它变形的底部。
本发明还有一个目的是提供一种用于广口塑料容器的结构，这种容器可以一个在另一个顶部上地与类似的容器有效地叠置，并且可以借助于高速制造设备以保证质量和性能恒定的、经济的方式制造。
更具体地说，本发明提供一种用于吹塑塑料容器的多功能底部。该底部有不连续地凹入的外环形壁，所述外环形壁带有在其间形成一站立环的一外壁部和一内壁部。该底部还有一内环形壁，它从外环形壁的内壁部向内向上延伸，并具有一内周缘和一外周缘。内环形壁的外周缘有在站立环上方的一高度处向外延伸的多个径向辐部，并且内环形壁的内周缘连接至一防倒置的、向上凸出的拱顶。功能上，内环形壁能响应在灌装和密封好的容器中压力的变化而向上和向下弯曲，且不会发生不想要的永久变形。此外，较佳地是，一肩部在外环形壁的内壁部上且在站立环的一水平面的上方径向向内延伸，以方便具有类似底部的容器的竖向叠置。
附图说明
当结合附图阅读了下面的描述之后，本发明的前述和其它的目的、特征以及优点应该会变得清楚。
图1是具有一实施本发明的底部的一容器的立体图；
图2是图1中所示容器的正视图；
图3是图1所示底部的一仰视平面图；
图4是沿着图3中的线4-4截取的底部的剖视图；
图5是沿着图2的线5-5截取的底部的剖视图，并示出了呈叠置的一对容器。
具体实施方式
本发明提供一种尤为适合于用作一包装食品的广口瓶的容器10。例如，容器10可以用来包装诸如苹果酱、空心粉的调味汁、开胃的调味品、泡菜、婴幼儿食品以及类似的流质或半流质食品。它也可以用来包装悬浮在盐水中的诸如腌制品之类的固体食品。因此，容器10可以用来包装各种食品，并且可以经受各种灌装和处理操作，如下文所述。
如图1所示，在本发明的一个较佳实施例中，一容器10设置成具有一底部12、一大致呈圆筒形的侧壁14以及一广口带螺纹的结束部分16，该结束部分经由一肩部18从侧壁14的上端凸伸出。较佳地，如图所示，上和下标签挡部20和22定位成分别与肩部18和底部12邻接，并在侧壁14上大致围成一圆筒形的标签区域24。这样，一标签(未示出)可以附着在侧壁14上并完整地延伸一圈。此外，较佳地是，侧壁14具有一系列的周向凹槽26，这些凹槽26对侧壁14的圆筒形形状进行加强，并防止侧壁14发生嵌入、下凹和其它所不希望发生的变形。
因为容器10既可以在热灌装中使用，又可以在加热杀菌/蒸馏处理中使用，所以它是多功能的。为了实现这个目的，底部12具有这样一种结构，它能适应在加热杀菌/蒸馏处理的过程中所经受的上升的容器内部压力，也能适应在热灌装或加热杀菌/蒸馏处理之后一灌装好的密封容器冷却后所经受的容器容积减小。为了这个目的，当灌装和密封好的容器内压力上升时，底部12以受控的方式向下弯曲并到达一想要的程度，并且当灌装和密封好的容器内形成真空时，底部12以受控的方式向上弯曲并达到一想要的程度。
结构上，底部12包括一不连续地凹入的外环形壁28，该环形壁28包括多个与底部12的外周缘32相邻的、间隔开的弧形支承部30。如图所示，在该较佳的实施例中采用了四个支承部30；但也可以采用三个、五个或更多个支承部30。每一支承部30有朝下标签挡部22向上延伸的一外壁部34和向上向内延伸入其余的底部结构的一内壁部36，如下文将述。在外和内壁部34和36接合处形成一站立面38，借此来形成容器10的一不连续的支承环。
一内环形壁40在不连续地凹入外环形壁28内延伸，并较佳地是相对水平面稍稍倾斜。较佳地，倾斜的内环形壁40在从其外周缘42向其内周缘44延伸时相对水平面向上和向内倾斜一角度“A”。例如，内环形壁40可以相对延伸穿过站立面38的一水平面“P”倾斜一在约5°至约6°的范围内的角度“A”。或者，内环形壁40可以大致形成为是平面的，并平行于一延伸穿过站立面38的水平面“P”。
内环形壁的40的外周缘42与各支承部30的内壁部分36结合，并与位于与底部12的外周缘32相邻处的多个间隔开的、水平设置的径向辐部46结合。每一辐部46在诸支承部30之间延伸，并且在延伸穿过站立面38的水平面“P”上方的一高度处连接至容器侧壁14。内环形壁40的内周缘44结合进入一向上凸伸入容器10内的防倒置拱顶47。较佳地，内环形壁40和防倒置拱顶48经由一环形铰接部50结合。如图4所示，防倒置拱顶48具有一邻接铰接部50的一圆锥形下部52和一凸起的上部54部分。
内环形壁40用作一弯曲板。为了这个目的，当灌装和密封好的容器内的内部压力增加时，内环形壁40向下弯曲，如图4中的虚线“B”所示，以适应增加的压力，并防止容器10的侧壁14承受所不想要的永久变形。此外，当热灌装和封盖好的容器或者灌装、封盖并接着进行加热杀菌的容器的内容物冷却到室温时，内环形壁40向上弯曲以减小真空度。这示于图4中的虚线“C”。这样，当密封的容器和内容物冷却至室温时，侧壁14大致呈圆筒形且与其形成时的形状没有变化，并且侧壁14能整齐地支承一包绕的标签，而不会带有在标签下的不需要的空隙或类似的部分。此外，侧壁14能抵抗成为椭圆的，并且底部12提供一水平的、不会发生摇摆或其它类似问题的安置表面。
防倒置的拱顶48、诸支承部30以及诸径向辐部46支承内环形壁40，并使其能仅在一想要的运动范围内弯曲，如虚线“B”和“C”所示。例如，内环形壁40由于容器内压力的增加而向下弯曲，但通过防倒置的拱顶48来防止其完全地倒置和失效，该防倒置的拱顶48随着内环形壁40一起运动，但不管容器内所经受的内部压力如何，它都大致保持一不变的形状。
本发明的底部12的另一特征是，各弧形支承部30的内壁部36有形成于其中的一弧形肩部或支承肩部56，所述弧形肩部或支承肩部在高度上与支承表面38和内环形壁40都间隔开，以便于类似的容器10竖向地叠置。例如，如图5所示，一上容器10a叠置在在一下容器10b上。上容器10a的底部12中的支承肩部56安置在下容器10b的盖子62的上表面60的外边缘58上，以使延伸穿过上容器10a的站立面38的水平面“Pa”在下容器10b的盖子62顶表面60下方一间隔开的距离处延伸。
以举例的方式，而非以限制的方式，根据本发明的容器10较佳地具有一约5.8英寸的高度“H”、一约4.2英寸的容器外径“D”，并具有约32液量盎司的容积。由站立面38所形成的不连续的站立环的直径约为3.6英寸，并且底部12的内环形壁40具有一直径约1.6英寸的内周缘44和一直径约2.2英寸的外周缘42。诸径向辐部46均匀地间隔开，并分隔各个支承部30，以使每个支承部30至少为约0.8弧度。此外，每一支承部30的弧形延伸程度比各径向辐部46的弧形稍大。
较佳地，容器10是用PET、PEN或其混合物制成的注模预制件吹塑成的，或者是用PP制成的吹塑挤出件。此外，容器10可以是包括一层隔气材料或一层碎屑材料的多层结构。较佳地，容器的结束部分16是带有螺纹的、吹塑制成的，并且对上述形成的适应特征是密封的。
上述容器10能使用在灌装温度高至205°F的热灌装操作中。它也可以用在加热杀菌的处理中，其中，在容器10内诸如腌制品之类的一冷的固体食品与120至140°F的中度加热的盐水结合。在容器10封盖之后，可以穿过一加热杀菌槽来对灌装好的容器进行处理，在该槽中温度接近约212°F，以使在密封容器中的固体产品加热到大致175°F并持续15分钟，然后灌装和密封好的容器冷却到室温。
尽管已经详细地描述了一较佳的容器和底部结构，但是不超出所附权利要求书中所定义的本发明原理和保护范围，还可以作出各种修改、替代和改变。
