摘要： A plurality of collapsible bags are integrally formed in a tubular blank of a flexible material with a perforated portion disposed between adjacent bags to facilitate separating them. When formed, adjacent bags are connected in end-to-end relationship and lie generally flat such that the elongate blank may be wrapped around itself forming a roll of the bags or the bags may be pleated or accordion folded flat within a container whereby they may be individually removed from the container for use. Handles are preferably integrally formed with each bag extending from adjacent the top wall of the bag. A spout is preferably also integrally formed with the bag to facilitate filling and emptying of the bag. The bags are particularly suited to contain liquids or frozen liquids and are preferably made of a food-grade plastic film material suitable to contain various foods or beverage products. The bags may each be received in a separate container to support a filled bag. To facilitate emptying a bag received in a container, the container may be received on a base tray having an inclined surface to tilt the container so that the contents of the bag collect at a lowest portion of the bag. A spout support may be provided to hold the spout open and to prevent the bag from collapsing around the spout during filling or emptying of the bag. To facilitate lifting, hanging or moving a bag, a bag carrier may be provided having a U-shaped channel constructed to receive a rod over which the handles of the bag are received.
摘要翻译：多个可折叠袋整体地形成在柔性材料的管状坯料中，其中穿孔部分设置在相邻的袋之间，以便于分离它们。当形成时，相邻的袋子以端对端的关系连接并且大致平坦地延伸，使得细长的坯件可以围绕其自身缠绕形成一卷袋子，或者袋子可以在容器内折叠或折叠成平坦的折叠，单独从容器中取出使用。手柄优选地与从袋的顶壁相邻延伸的每个袋整体形成。喷嘴优选地也与袋一体地形成，以便于袋的填充和排空。这些袋子特别适于容纳液体或冷冻液体，并且优选由适于容纳各种食品或饮料产品的食品级塑料薄膜材料制成。袋子可以分别容纳在单独的容器中以支撑一个充满的袋子。为了便于将容纳在容器中的袋子排空，容器可以容纳在具有倾斜表面的底盘上，以使容器倾斜，使得袋的内容物收集在袋的最低部分。可以提供喷口支撑件以将喷口保持打开，并且防止袋子在填充或排空袋子期间在喷嘴周围塌陷。为了便于提起，悬挂或移动袋子，可以提供具有U形通道的行李架，该U形通道被构造成容纳接收袋的手柄的杆。
