Abstract

Abstract A latch for a reclosable carton construction and blank therefor wherein means are provided to engage a reclosable tab on a male locking member so as to resist its natural tendency to spring back when it is in its locked position. In the preferred form of the invention, the female locking member as well as the means to prevent spring back of the male locking member are each formed in a conventional glue line panel. The male and female locking members are so positioned and arranged in an overlapping relationship that the male locking member snaps into its locked position. A novel pushbutton-type unlatching member is provided integral with a male locking member to reopen the closed carton.
