A portion of the film strip which overlies the vent opening is designed to be released from closure wall for equalizing the pressure within the container with that external thereto by pulling up on an unsecured end portion of the film strip. Furthermore, after releasing of the vacuum in the container, the film strip is able to be re-adhered over the vent opening. Additionally, the vent opening and the film strip are located within a locally recessed portion of closure wall so as to prevent inadvertent dislodging of the film strip or damage to it. |
