Abstract: A liquid storage tank and a method of fabricating and testing the liquid storage tank. The tank is collapsible for ease of transportation when not holding a liquid and includes a base portion and a top portion. The base portion has a bottom wall and a frusto-conical sidewall that is sealed to the bottom wall. The top portion is sealed to the sidewall, and has a flexible opening. The opening is linear in the preferred embodiment and is openable to draw liquid from the tank and closable to prevent contaminants from entering the tank. The bottom wall is substantially circular and the top portion includes two substantially semi-circular sections joined and overlapped along the straight edges to form an overlapped region. The sidewall includes generally triangular shaped sections, and the sections are joined to one another with seams that extend in a slightly helical fashion about the tank. The opening includes a slit in the overlapped region and two L-shaped members. Each L member has a horizontal leg and a vertical leg. The vertical legs are adjacent one another with the slit located therebetween. The horizontal legs are attached to the top portion. The vertical legs have sealed extended ends and include a releasable closing mechanism for opening and closing the opening. The liquid storage tank may be inverted through the opening for ease in cleaning the tank, and the tank may be placed on an incline of up to at least ten degrees with the tank being filled to capacity and wherein no liquid will spill from the opening. A method of pressure testing the tank is provided.

Abstract translation: 液体储罐和液体储罐的制造和测试方法。 当不保持液体并且包括基部和顶部时，罐可折叠以便于运输。 基部具有底壁和与底壁密封的截头圆锥形侧壁。 顶部密封到侧壁，并且具有柔性开口。 该开口在优选实施例中是线性的，并且可打开以从罐中抽出液体并且可关闭以防止污染物进入罐。 底壁基本上是圆形的，并且顶部部分包括两个基本上半圆形的部分，其沿着直边缘连接和重叠以形成重叠区域。 侧壁包括大致三角形的部分，并且部分彼此连接，接缝以围绕罐的稍微螺旋的方式延伸。 开口包括重叠区域中的狭缝和两个L形构件。 每个L会员都有一个水平的腿和一个垂直的腿。 垂直腿彼此相邻，狭缝位于它们之间。 水平腿连接到顶部。 垂直腿具有密封的延伸端，并且包括用于打开和关闭开口的可释放的关闭机构。 液体储存罐可以通过开口倒置以便于清洁罐，并且罐可以被放置在高达至少十度的倾斜处，罐被填充到容器中，并且其中没有液体将从开口溢出。 提供了对罐进行压力测试的方法。
