    • A removable internal support for a flexible bag made of flexible material with material memory so that the removable internal support for a flexible bag will attempt to return to a flat configuration when rolled up: Locking apertures constrain the removable internal support for a flexible bag in a rolled-up configuration for insertion into a flexible bag. Rounded corners defined by the intersection of a bottom edge and a top edge with vertical edges, and rounded intersection corners at the intersections of the locking apertures with the vertical edges, prevent the removable internal support for a flexible bag from snagging a flexible bag in which it is installed. The locking apertures are quickly and easily released once the removable internal support for a flexible bag is in position in the flexible bag. After being unlocked from its rolled-up configuration, the material memory inherent in the removable internal support for a flexible bag attempts to return the removable internal support for a flexible bag toward a flat configuration, but is constrained in an approximately cylindrical shape by the flexible bag in which it is installed. The flexible bag may then be filled, and the removable internal support for a flexible bag subsequently removed by simply pulling it out of the bag. The flexible bag may then be tied shut and disposed of in the conventional fashions, and the removable internal support for a flexible bag is ready for re-use.
    • 用于由柔性材料制成的柔性袋的可拆卸内部支撑件,具有材料存储器,使得用于柔性袋的可拆卸内部支撑件将在卷起时尝试返回到平坦构造:锁定孔限制可拆卸的内部支撑件,用于柔性袋 卷起构型用于插入柔性袋中。 由底部边缘和顶部边缘与垂直边缘的交点限定的圆角,以及锁定孔口与垂直边缘的交叉点处的圆形交叉点,防止可拆卸的内部支撑件用于柔性袋,以阻止柔性袋,其中 它已安装。 一旦柔性袋的可拆卸的内部支撑件在柔性袋中就位时,锁定孔就能快速且容易地被释放。 在从卷起构型解锁之后,用于柔性袋的可拆卸的内部支撑件固有的材料存储器试图使柔性袋的可拆卸内部支撑件朝向平坦构造返回,但是通过柔性袋 它的安装包。 然后可以填充柔性袋,并且通过简单地将其从袋中拉出来,可移除的用于柔性袋的可拆卸内部支撑件随后被移除。 然后可以将柔性袋绑扎并以常规方式处理,并且用于柔性袋的可拆卸的内部支撑件准备好重新使用。
