(57) A thermoplastic coated square or rectangular container suitable for being filled with a juice concentrate which is frozen after filling, and having a top closure arrangement adapted to being readily fully opened to permit the frozen juice to be discharged through the top opening thereof. The top closure arrangement includes narrow edge panels on three sides thereof, with panel segments connected to each by weakened or perforated lines. The segment connected to the front edge panel is folded back onto itself around the weakened or perforated line and includes a lift tab extending therefrom. A cover panel is secured to the two side edge panels and the three panel segments such that the cover panel is peeled away from the three edge panels by manually lifting the lift tab and breaking the three weakened lines, to cause the three panel segments to be lifted with the cover panel. Hence, there is provided a substantially completely open top for discharging the frozen juice concentrate therethrough.
