ABSTRACT:
This disclosure relates to a pull tab for removing a removable panel portion of an easy opening container and thereafter effecting the folding up of the removed removable panel portion in an out-of-the-way position with respect to a resultant dispensing opening and with the removable panel portion being encased within the folded up tab. The tab is formed of plastics material which is so molded, preferably by an injection molding process, so as to have a memory in the form of a plurality of transversely extending memory fold lines. The memory fold lines are operable progressively to fold or roll up the tab in pup tent style to assume a triangular cross section. The removable panel portion is provided with transverse fold lines in alignment with the memory fold lines so as to be folded up together with and within the tab. The tab is permanently secured to the container panel.
