    • A bag suitably for mixing has a compartment, a pocket in the bag having a mouth opening so that either it can be filled with liquid to a predetermined volume or it can receive a dispensing member. The pocket is easily ruptured when the mouth is closed and, when mixing, a volume of liquid may be discharged into the compartment for mixing with a material in the compartment. During mixing the walls of the pocket abut to serve as a non-return valve in the bag.Apparatus for making the bags includes web bonding means, feeding means to feed film of waterproof thermoplastics material from rolls to the bonding means, and interrupting means to form the mouth in the pocket.The apparatus may form bags with open bottoms for insertion of the material for mixing and subsequent closure or sealed, filled bags.
    • 适于混合的袋子具有隔间,袋中的口袋具有开口,使得其可以用液体填充到预定体积,或者可以接收分配构件。 当口关闭时,口袋容易破裂,并且当混合时,一定体积的液体可以排出到隔室中以与隔室中的材料混合。 在混合期间,袋的壁邻接以用作袋中的止回阀。 用于制造袋的装置包括纸幅粘合装置,用于将防水热塑性材料的薄膜从辊供给到粘合装置的进料装置,以及在袋中形成口的中断装置。 该装置可以形成具有开口底部的袋,用于插入用于混合的材料以及随后的封闭或密封的填充袋。
