用于液体的柔性容器及其制造方法
摘要：
一种用于液体的柔性容器，它包括：两个柔性材料的壁(15，16)，所述壁的重叠的自由边缘通过周缘焊缝(2)连接，以便限定所述容器的密封内腔；自密封的倾倒喷嘴(3)，该喷嘴位于所述容器的拐角处，并且包括朝向所述容器的外部设置的喷口(4)、和用于将喷口连接到所述容器的内腔的出口通道(5)；以及自封闭阀门，该阀门包括一个或多个由两个壁的焊接形成的障碍物焊缝(6)，所述障碍物焊缝设置在所述内腔内，基本上与通向喷口的通道相对并邻近该通道，以限制内腔与出口通道之间的液体的流动通路的截面，从而留出至少一个狭窄通道；其中，出口通道通过在由周缘焊缝限定的内腔内的通道的每侧上的焊缝形成，该周缘焊缝是具有小于80°锐角的平行四边形形状，倾倒喷嘴位于所述容器的具有锐角的拐角中。
摘要（英）：

A flexible receptacle for liquid, comprising two walls of a flexible material, the superimposed free borders of the said walls being joined by a peripheral weld seam in order to define a sealed internal volume of the said receptacle, a self-sealing pouring nozzle in a corner of said receptacle comprising a spout located towards the outside of the said receptacle, an outlet channel connecting the spout to the internal volume of the said receptacle, a self-closing valve comprising one or more obstacles formed by welding of the two walls and arranged in the said internal volume essentially opposite and close to the channel leading to the spout so as to limit the cross-section of the flow-passage of the liquid between the internal volume and the outlet channel, leaving free at least one narrow channel,; wherein the outlet channel is formed by a weld either side of the channel within the volume defined by the peripheral seam, said peripheral seam has a parallelogram shape having an acute angle of less than 80 DEG , and the pouring nozzle is positioned in a corner of the said receptacle with an acute angle.
