    • The flexible storage bag includes overlaying first and second sidewalls defining an internal volume that can be accessed form an open top edge. To evacuate air from the internal volume after the open top edge has been closed, the bag includes a one-way valve element attached to the first sidewall and communicating with the internal volume. To prevent the one-way valve element from becoming clogged by the opposing second sidewall, the bag also includes a clearance member that maintains at least a partial clearance between the first and second sidewalls proximate the valve element. The clearance member can take many forms such as a textured portion on the second sidewall that includes evacuation passages which provide air in the internal volume access to the valve element, a permeable element covering the valve element, and a rigid or compressible structure that spaces the second sidewall from the valve element.
    • 柔性储存袋包括覆盖第一和第二侧壁,第一和第二侧壁限定能够从敞开的顶部边缘进入的内部容积。 在打开的顶部边缘已经关闭之后,从内部空间排出空气,袋子包括连接到第一侧壁并与内部容积连通的单向阀元件。 为了防止单向阀元件被相对的第二侧壁堵塞,袋还包括间隙部件,其在靠近阀元件的第一和第二侧壁之间保持至少部分间隙。 间隙构件可以采取许多形式,例如第二侧壁上的纹理部分,其包括抽空通道,其提供内部容积进入阀元件的空气,覆盖阀元件的可渗透元件,以及刚性或可压缩结构, 第二侧壁。
