Claim:
Sealed container filled with water for making ice, of the type comprising a tray having a peripheral wall closed on one side by a base and defining on the other side an opening for extracting the ice, the container comprising an inner seal for sealing the sealed tray above the opening, wherein the base has a deformation protruding inside the tray that defines externally a transverse groove extending from one side of the base to the other and opening at each of its extremities on the peripheral wall of the tray, this base having two ridges extending on both sides of the groove, and wherein, the base having a substantially rectangular outline, the groove extends in the median part of the base substantially over a third of the width of said base and has externally a concave base having a substantially curved transverse section whose concavity reverts itself in a median part of a flange that is connected tangentially to the top of the ridges, the depth of the groove and thus the height of the ridges being substantially the same as the width of said groove, and the concave base of the groove having a bottom in a straight line from one of its extremities to the other.
