A pre-filled ice cube bag containing freezable material comprises two sheet- shaped foil layers having substantially identical geometrical configurations and defining an outer periphery. The two sheet-shaped foil layers each defines a surface area of a minimum of 75cm2. In the bag, a peripheral joint extends along the outer periphery of the foil layers, which peripheral joint joins the foil layers together and defining a sealed inner chamber in the interior of the bag. The inner chamber defines a given inner volume when the two sheet- shaped foil layers are inflated to a maximum at a given maximum pressure of not less than 0.5 m water column pressure and is divided into two or more ice cube. The freezable material constitutes a filling of no less than 80% of the inner volume in a non-frozen condition, but less than 91%.

L'invention concerne un sac à glaçons prérempli qui contient une matière congelable, à deux couches de matériau feuille de configuration géométrique sensiblement identique, définissant une périphérie externe. Les deux couches définissent chacune une surface d'au minimum 75cm?2¿. Dans ce sac, un joint longitudinal s'étend le long de la périphérie externe des deux couches, réunissant les deux couches et définissant une chambre interne hermétique à l'intérieur du sac. Ladite chambre interne définit un volume interne donné, lorsque les deux couches sont gonflées au maximum à une pression maximum donnée non inférieure à 0,5 m (pression de la colonne d'eau), et elle est divisée en deux ou plus de deux compartiments à glaçons. La matière congelable remplit au moins 80 % du volume interne à l'état non congelé, mais moins de 91 % de ce volume.
