When we open cartons,we are used to using tools, such asscissors, knives, etc., when there is no such tools, demolition becomes difficult. Therefore, in order to be more convenientand and more rapid to open cartons, I found this design.it is a hole open on the side of cartons,we just need to push it in ,and then,the tap will be easy to remove.
