Abstract
An attachment for a flexible package is disclosed to enable the user to fasten a re-closable package. A bifurcated adhesive member is secured to the body portion of the package at a distance from the opening thereof. The member has a jaw-like construction with hingeline about which one of the jaws may pivot. When the jaws are opened by the user, the re-closed, folded end of the package may be inserted therebetween, and the jaws subsequently closed to retain the package in re-closed condition. It is particularly useful for flexible packages of corn flakes, potato chips, cheese, etc., where portions of the contents are removed over a period of time, gradually decreasing the volume of the contents and forming a sequentially smaller package which should be re-sealed to preserve the freshness of the contents.
