具有可移动压力面板的压力增强塑料容器及其处理方法
Pressure reinforced plastic container having a moveable pressure panel and related method of processing a plastic container
US-8381940-B2一种通过内部压力增强瓶壁强度的塑料容器。
专利摘要
一种塑料容器包括上部，其包括适于接收封闭件的瓶口；下部，其包括底座；以及在上部和下部之间延伸的侧壁。上部、下部和侧壁限定用于存储液体内容物的内部容积。塑料容器还包括位于容器上的压力面板，该压力面板可在初始位置和激活位置之间移动。压力面板在填充容器之前位于初始位置，并在填充和密封容器之后移动到激活位置。将压力面板从初始位置移动到激活位置减小了容器的内部容积并在容器内部产生正压力。正压力增强了侧壁。还公开了一种处理容器的方法。
Original abstractA plastic container comprises an upper portion including a finish adapted to receive a closure, a lower portion including a base, and a sidewall extending between the upper portion and the lower portion. The upper portion, the lower portion, and the sidewall define an interior volume for storing liquid contents. The plastic container further comprises a pressure panel located on the container and moveable between an initial position and an activated position. The pressure panel is located in the initial position prior to filling the container, and is moved to the activated position after filling and sealing the container. Moving the pressure panel from the initial position to the activated position reduces the internal volume of the container and creates a positive pressure inside the container. The positive pressure reinforces the sidewall. A method of processing a container is also disclosed.
