    • A collapsible container (2, 3) is provided with a one-way valve (1). The valve comprises a cupola shaped slitted membrane forming a closure head (8) to allow dispensing a liquid contained in the container by opening the membrane under liquid pressure. When pressure is reduced the membrane will close and prevent the entrance of air into the container. To avoid a deformation of the membrane in counter dispensing direction a supporting column (20) is arranged within the valve ending in a distance from the lower side of the membrane. This column will prevent an opening of the membrane closure head towards the container storage room when air pressure in direction into the container is too high to be borne by the membrane closure head alone.
    • 一种可折叠容器设有一个单向阀。 所述阀包括圆顶形开缝膜形成封头,以允许通过液体压力下打开的膜分配容纳在容器中的液体。 当压力降低,膜将关闭,防止空气进入到容器中。 为了避免在计数器分配方向上的膜的变形的支撑柱在从膜的下侧的距离终了的阀内布置。 该列将在朝向容器的储藏室的膜封头的开口防止当方向进入容器的空气压力过高要由膜封头独自承担。
