Abstract: A multipurpose bag is formed of two plastic foil layers joined together to define a top, a bottom, and opposing sides. Peripheral joints between the layers extend along the bottom and the sides to define an inner chamber, the joint along one of the sides being divided by an unjoined area into top and bottom parts. A separation joint extends from the top part of the divided side peripheral joint toward the bottom peripheral joint, dividing the chamber into top and bottom chambers. The top defines a top opening communicating with the top chamber, and the unjoined area defines a side opening communicating with the bottom chamber. The separation joint restricts communication between the top and bottom chambers for preventing a solid product in the top chamber from passing into the bottom chamber, while allowing liquid to pass from the top chamber to the bottom chamber. Liquid may then be expelled from the bottom chamber through the side opening.

Abstract: A freezing mould bag for ices is formed from two plastic foils, and has a segmented inlet channel, two closure valve flaps extending within the interior of the bag, and a constriction which provides a venturi effect closing the bag at the constriction.
