Description

具有波浪形凹槽的热填充容器
技术领域
本申请和所产生的专利总体上涉及饮料容器，并且更具体地涉及具有凹槽和面板结构的轻质饮料瓶，所述结构以高度美学的设计提供用于适应典型与热填充过程有关的力的增加的刚度。
背景技术
例如运动饮料、果汁、茶、水等的饮料通常通过热填充过程进行装瓶，以防止微生物生长。热填充过程通常涉及将饮料在大约95摄氏度巴氏灭菌大约20秒、将饮料冷却至大约85摄氏度、以及随后将饮料注入瓶体中。85度的温度通常足以将瓶体灭菌。然后向瓶体施加封盖以产生密封的容器。在填充和封盖后，瓶体然后可以经过有待经由喷水或其他方法冷却的冷却通道。饮料在冷却过程之后的最后温度通常可以低于大约40摄氏度。其他类型的使用不同时间、温度、以及设备的热填充过程可以是已知的。不同类型的饮料也可能需要不同类型的装瓶技术。
在冷却过程期间，饮料可能收缩，使得在封闭的容器内形成真空。为了帮助抵消这种真空的影响，在热填充过程中使用的瓶体通常其中形成有特殊的真空板。这些真空板和其间的区域总体上有助于受控的变形或偏转，以便适应由真空产生的力，同时保持瓶体的整体完整性。与冷填充瓶体等相比，这些热填充瓶体通常需要相对复杂的形状并且可能使用明显更多的热塑性塑料材料。结果，热填充瓶体可能就加工工具和材料二者而言生产更昂贵，并且还可能提供较少的设计自由度。
因此期望改进的热填充容器以及填充这些容器的方法。这种改进的容器可以适应其中的饮料的收缩，同时保持容器的整体完整性，而不具有典型与热填充容器等有关的复杂性、重量、以及成本。
发明内容
本申请和所产生的专利因此提供了一种用于在热填充过程中填充的饮料的容器。所述容器可以包括上部区段和下部区段。所述下部区段可以包括限定多个舌形面板的波浪形凹槽，并且其中，所述波浪形凹槽可以包含大体上Z状的形状。
本申请和所产生的专利进一步提供了一种瓶装热液体的方法。所述方法可以包括以下步骤：沿所述容器的区段定位波浪形凹槽和多个舌形面板；以热液体填充所述容器；冷却所述容器；在所述容器内形成真空；以及使所述容器围绕所述波浪形凹槽和所述舌形面板挠曲。
本申请和所产生的专利进一步提供一种250毫升的容器。所述容器可以包括上部区段和下部区段。所述下部区段可以包括平分第一舌形面板和第二舌形面板的连续的波浪形凹槽，并且其中，所述波浪形凹槽可以包含大体上Z状的形状。
当结合若干附图和所附权利要求时，本申请和所产生的专利的这些和其他特征以及改进对本领域普通技术人员而言在审视以下详细说明时将变得清楚。

具体实施方式
现在参照附图，在这几个图中类似的数字指代类似的元件，图1至图7示出了如本文中可以描述的一种容器100。容器100可以呈瓶体110等的形状。瓶体110可以具有任何合适的尺寸、形状、或者构型。瓶体110可以由注射模制的预成型件制成。预成型件可以由多种类型的聚合物树脂制成。这些聚合物树脂可以包括聚酯、聚烯烃、聚丙烯、聚碳酸酯、硝化物和其共聚物。通常可以使用双轴取向的聚对苯二甲酸乙二酯(“PET”)。本文中还可以使用比如聚乳酸(“PLA”)等的其他材料。聚合物可以是透明或不透明的。本文中可以使用其他类型的材料。
总体来说，瓶体110可以包括开放口部120、瓶口130、肩部140、上部区段150、下部区段160、以及呈任何期望的尺寸、形状、或构型的基部170。开放口部120和瓶口130可以很大程度上是常规设计的。瓶口130可以具有在其上的一个或多个螺纹180。瓶口130和螺纹180可以被确定尺寸为在其上容纳封盖(未示出)。封盖可以很大程度上是常规设计的。肩部140可以很大程度是圆顶状形状、并且在直径上从瓶口130向下向该上部区段150扩大。肩部140的尺寸、形状、以及构型可以变化。
上部区段150可以从肩部140延伸至下部区段160。上部区段150可以通过上部圆周凹槽190与肩部140分隔开。上部区段150可以通过中部圆周凹槽200与下部区段160分隔开。凹槽190、200可以呈瓶体110的侧壁220中的凹痕210的形状。凹槽190、200和凹痕210的尺寸、形状、以及构型可以变化。上部区段150可以具有形成于其中的一个或多个上部区段圆周凹槽230。虽然只示出了一个上部区段圆周凹槽225，然而本文中可以使用呈任意合适的尺寸、形状、或构型的任意数量的圆周凹槽。上部区段150可以具有从上部圆周凹槽190到中部圆周凹槽200稍微减小的直径。本文中可以使用其他部件和其他构型。
下部区段160可以从上部区段150延伸至基部170。下部区段160可以通过中部圆周凹槽200与上部区段150分隔开。下部区段160可以通过下部圆周凹槽230与基部170分隔开。下部圆周凹槽230的尺寸、形状、以及构型可以变化。下部区段160可以具有稍微“沙漏”状构型240，所述构型具有上部直径减小区域250和下部直径增大区域260。沙漏状构型240的本质可以变化。
下部区段160中可以具有在其中的一个或多个波浪形凹槽270。波浪形凹槽270可以以成角度的构型从下部圆周凹槽230以重复形式205延伸至中部圆周凹槽200。虽然示出三个(3)重复部205，但本文中可以使用任何数目。在本示例中，示出了呈围绕整个下部区段160的连续环280一个波浪形凹槽270。本文中可以使用连续形式或不连续形式的任何数目的波浪形凹槽270。波浪形凹槽270还可以是瓶体110的侧壁220内的凹痕210。波浪形凹槽270的凹痕210的深度和宽度可以变化。
波浪形凹槽270的每个重复部205可以以大体上“Z状”形状280跨下部区段160延伸。通过术语“Z状”形状280，我们指代沿下部区段160的长度(即在瓶体110的纵向轴线方向上)的竖直线截断波浪形凹槽270一次、两次、或三次。波浪形凹槽270和大体上“Z状”形状280可以在其间限定瓶体110的侧壁220中的多个舌形面板290。具体地，波浪形凹槽270的“Z状”形状280在其间形成舌形形状的的面板290。在使用单个连续波浪形凹槽270的情况下，波浪形凹槽270可以平分第一连续舌形面板300和第二连续舌形面板310。此外，舌形面板290可以具有变化的波状外形形状320，所述变化的波状外形可以沿其长度变化。波浪形凹槽270和舌形面板290的尺寸、形状、以及构型可以变化。本文中可以使用其他部件和其他构型。
基部170可以从下部区段160延伸。基部170可以通过下部圆周凹槽230与下部区段160分隔开。基部170可以是常规设计的并且可以具有任何合适的尺寸、形状、或构型。基部170可以与通常在冷填充过程中使用的基部的设计相似。
本文中，瓶体110可以用于旨在用于具有标准的28毫米的瓶口130和标准的基部170的大约250毫升的饮料尺寸。瓶体110可以具有大约167毫米左右的整体高度。然而，瓶体110及其特征可以根据期望放大或缩小尺寸。在250毫升的尺寸中，瓶体110可以使用大约15克或更少PET材料或其他类型的热塑性塑料。波浪形凹槽270的凹痕210可以在瓶体110的侧壁220内延伸大约3.3毫米到大约3.7毫米左右。在当前示例中可以是大约3.5毫米。凹痕210的深度可以变化。
在使用中，瓶体110可以以传统的热填充过程填充并且在传统的加盖工位中加以封盖。随着瓶体110中的饮料冷却，饮料将会收缩并且开始在其中抽真空。与可以设计为通过关于基部变形来适应真空的传统热填充容器相比，本文中的瓶体110由于使用了下部区段160中波浪形凹槽270和舌形面板290而具有改善的刚度。波浪形凹槽270和舌形面板290允许有限的弯折和挠曲来吸收真空，同时保持瓶体110的完整性和形状。Z状的形状280的使用也可以允许受控量的扭曲来适应其中进一步的真空。如果在颈圈下的整个表面面积大约为26,426平方毫米，并且下部区段160的表面面积为大约11,461平方毫米，则挠曲的下部区段160与瓶体110的整体的整体比例可以是大约百分之43.3。下部区段160的直径减小可以小于大约1.5％左右。此外，上部区段150提供具有改进的环向强度和改进的顶部加载的舒适的抓握。标签或其他类型的包装物可以以传统的方式整体或部分地贴到瓶体110上。
明显地，波浪形凹槽270，Z状的形状280和舌形面板290的使用以减少的材料量提供了这种刚度。即使在250毫升的尺寸的情况下，传统的热填充瓶体可能需要附加的材料，尤其是在瓶体通过基部适应真空的情况下更是如此。因此，减少量的材料明显节省了热填充瓶体的成本。本文中，瓶体110可以是超轻的但是具有改善的刚度。在使用用于250毫升的瓶体的少于大约15克的材料的情况下，材料与尺寸的比例因此可以是大约一(1)比十七(17)或更小。
应当清楚的是，前文仅涉及本申请和所产生的专利的某些实施例。本文中，本领域普通技术人员可以在不背离所附权利要求及其等效物所限定的本发明的总体精神和范围的情况下进行许多改变和更改。
