    摘要： A flexible pouch includes a flexible compartment with a bottom. A rim is formed around the bottom of the compartment and is spaced from and extends outwardly from this compartment bottom. At least three coplanar feet are provided on the rim for stabilizing the pouch when the pouch is resting on the rim. These coplanar feet can be generally flush with the rim when the pouch is in a flat, empty position. However, when the compartment of the pouch is filled, the coplanar feet will be formed as the lowermost portions of the rim. The pouch will rest on these coplanar feet when on a support to be stably held in position. This pouch design will avoid wobbling or tipping over of the pouch and therefore minimize or eliminate product spillage. Also, a method for making this pouch includes the steps of forming the pouch with the compartment, providing a rim around the bottom of the compartment, and spacing the rim from the bottom of the compartment. A portion of this rim is then removed at the outer edge to form the plurality of coplanar feet.

    摘要： A flexible pouch includes a flexible compartment with a bottom. A rim is formed around the bottom of the compartment and is spaced from and extends outwardly from this compartment bottom. At least three coplanar feet are provided on the rim for stabilizing the pouch when the pouch is resting on the rim. These coplanar feet can be generally flush with the rim when the pouch is in a flat, empty position. However, when the compartment of the pouch is filled, the coplanar feet will be formed as the lowermost portions of the rim. The pouch will rest on these coplanar feet when on a support to be stably held in position. This pouch design will avoid wobbling or tipping over of the pouch and therefore minimize or eliminate product spillage. Also, a method for making this pouch includes the steps of forming the pouch with the compartment, providing a rim around the bottom of the compartment, and spacing the rim from the bottom of the compartment. A portion of this rim is then removed at the outer edge to form the plurality of coplanar feet. A relatively wide-mouth opening is also provided on the pouch to enable easy insertion of a straw while minimizing or eliminating product spillage. This opening is formed from a frangible element or membrane. Also, the pouch provides for avoiding pressurization of the compartment during opening and provides a way for readily identifying the location of the opening to the pouch.

    摘要翻译： 柔性袋包括具有底部的柔性隔室。 围绕隔室的底部形成边缘并与该隔室底部间隔开并向外延伸。 在边缘上设置至少三个共面的脚，用于当袋子搁置在边缘上时稳定袋子。 当袋子处于平坦的空的位置时，这些共面脚可以与边缘大致齐平。 然而，当袋子的隔间被填充时，共面的脚将形成为边缘的最下部分。 当支撑件处于稳定的位置时，该袋将搁置在这些共面脚上。 这种袋设计将避免摆放或倾倒袋子，从而尽可能减少或消除产品溢出。 此外，制造该袋的方法包括以下步骤：用隔间形成袋，提供围绕隔室底部的边缘，并且将边缘与隔室的底部隔开。 然后在外边缘移除该边缘的一部分以形成多个共面的脚。 在袋子上还设有相对较宽的开口，以便在最小化或消除产品溢出的同时轻松插入吸管。 该开口由易碎元件或膜形成。 而且，该袋提供了在打开期间避免隔室的加压，并且提供了一种用于容易地识别开口到袋的位置的方式。
