Una bolsa para cubos de hielo comprende dos láminas en forma de hoja(12, 14; 12, 14) que definen una periferia externa. Una union periférica (20, 21,21a, 21b) está dispuesta a lo largo de la mayor parte de la periferia externa de las láminas, conla excepcion de un área periférica que constituye unaabertura de entrada de dicha bolsa (10). Esta union periférica une las láminas entre sí definiendo una cámara interna que está dividida en varioscompartimientos para cubos de hielo definidos poruni ones separadas (22,23, 24, 25, 29) de las láminas. Un canal de entrada está dispuesto desde la aberturade entrada a la cámara interna de la bolsa para de este modo permitir la admision del entorno a la cámara interna de la bolsa a través delcanal d e entrada.Cada una de dichas uniones separadas (22, 23, 24, 25, 29) está constituida por una cantidad de uniones individuales (22, 23, 24, 25, 29), estableciendo cadauna de dichas uniones individuales (22, 23, 24, 25, 29) una conexion entrelas dos l áminas de forma en hoja con tal resistencia de union y con tal limitadaárea de extension que la union individual no es rota cuando las láminas (12, 14; 12, 14) son sometidas a una fuerza de separacion, pero proporciona rasgado yseparaciono perforaci on (44) en una de las láminas (12, 14; 12, 14) a lo largo de la periferia de dihas uniones individuales. De este modo se obtiene unabolsa para cubos de hielo que es muy fácil de abrir rasgando y separando.An ice cube bag comprises two sheet-shaped sheets (12, 14; 12, 14) that define an outer periphery. A peripheral joint (20, 21,21a, 21b) is disposed along most of the outer periphery of the sheets, with the exception of a peripheral area that constitutes an inlet opening of said bag (10). This peripheral joint joins the sheets together defining an internal chamber that is divided into several compartments for ice cubes defined by separate ones (22,23, 24, 25, 29) of the sheets. An input channel is arranged from the entrance opening to the internal chamber of the bag to thereby allow the environment to be admitted to the internal chamber of the bag through the input channel. Each of these separate joints (22, 23, 24, 25, 29) is constituted by a number of individual unions (22, 23, 24, 25, 29), each of said individual unions (22, 23, 24, 25, 29) establishing a connection between the two sheets of sheet form with such joint strength and with such limited area of extension that the individual joint is not broken when the sheets (12, 14; 12, 14) are subjected to a separation force, but provides tearing and separating drilling (44) in one of the sheets (12, 14; 12, 14) along the periphery of said individual junctions. In this way an ice cube bag is obtained that is very easy to open by tearing and separating.
