Indian Tonic Water tins failing

Schweppes Indian Tonic Water tins burst for no reason even when stored in a cool dark room. The new tins are much thinner than the old ones and from a case of 24 we end up being able to use only half or less as all the others spoil, leak or burst for no reason. They are perhaps saving on packaging but will lose in the long run as the failure rate of the packaging means one ends up paying double for the product.
