HEY MATE HERE IS YOUR ANSWER:
ICE IS KEPT IN A DOUBLE WALLED OR DOUBLED PROTECTED CONTAINER SO THAT THE AIR OUTSIDE WILL NOT BE ABLE TO CHANGE THE TEMPERATURE INSIDE THE CONTAINER AND MELT ICE . THIS TYPE OF ARRANGEMENT ALSO HELPS IN KEEPING AWAY THE IMPURITIES OF DUST PARTICLES

This is a question on heat transfer.
The double wall has a vacuum in between them.
A vacuum contains no air.
The vacuum prevents heat gain by convection.
This in turn ensures that the ice does not melt.
The ice also does not gain heat through conduction.
Therefore The double wall prevents heat gain by conduction and convection.
