ABSTRACT:
An easy-open container includes a membrane forming the top edge of the container and hermetically sealing the contents thereof. Elements for opening the container are disposed on the membrane, and includes a first bead of thermoplastic material and a first perforated line for tearing across the membrane. In one embodiment the membrane is disposed inward from the mouth of the bag, leaving portions of the bag walls extending upward beyond the container top edge to form guide rails which facilitate opening of the container. One guide rail is removed as the bag is opened and remaining portions of the bag walls are offset to enhance access to the bag contents. A membrane for sealing the mouth opening of a bag-like structure is also provided, as are methods for making an easy-open container and for making a membrane having the strcutures aforesaid.
