Abstract: A closure for closing plastic bags or the like consists of two clamping legs connected together via a joint and a lock for holding the clamping legs in mutual engagement, the one clamping leg being provided with a recess extending along the axis of the clamping leg and the other clamping leg being provided with a rib which extends along its axis and which is adapted to be moved into the recess by movement of the two clamping legs towards each other, a member of the lock being formed on one clamping leg and the other member on the other clamping leg.

Abstract: A closure (10) for a bag (not shown), such as a plastic bag for freezing shaped lumps of ice for cooling drinks, consists of a channel member (14) adapted to receive an insertion member (16). Before the insertion member (16) is pressed into the channel member (14), the end of the bag (not shown) is inserted between the two, being closed in a fluid-tight manner when the two members, in the example shown interconnected by a hinge (27), are pressed together.The closure makes it possible to close bags for freezing ice lumps in a fluid-tight manner, allowing the bags to lie down in a deep-freeze cabinet without leaking and also making it easier to open the bags than when these are closed by means of knots of the like.

Abstract: In a disposable bag (10) for freezing ice lumps (15), the bonding areas (17) dividing the bag into compartments (16) are relatively weak, at least at temperatures below freezing point. With this arrangement, the ice lumps (15) can be freed by stretching and/or "massaging" the bag (10), so that the dividing bonding areas (17) are disrupted and the bag changed into one without compartments. The ice lumps (15) may then be removed singly or en masse from the bag (10).
