Abstract
A flip-top carton, which is especially suited for use with ice cream, has a locking reclosure feature, and may be tamperproof. The location of its locking elements facilitates opening, and its design enables the minimization of plies at stress points, so as to avoid cracking of the paperboard from which it is made.
