<p>A food container, of the type having a quantity of food vacuum-packed within a body of the container (1) with a closure (5) affixed on an open end of the body of the container, is provided with a low cost improvement for facilitating removal of the closure from the body of the container (1) in the form of a vent opening (12) extending through a wall (5a) of the closure overlying the open end of the container and a flexible film strip (14), a portion (14b) of which is sealed to the wall (5a) around an area overlying the vent opening (12). A portion (14b) of the film strip (14) which overlies the vent opening (12) is designed to be released from the 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 (14). Furthermore, after releasing the vacuum in the container, the film strip is able to be re-adhered over the vent opening. Additionally, the vent opening (12) and the film strip (14) are located within a locally recessed portion (16) of closure wall (5a) so as to prevent inadvertent dislodging of the film strip (14) or damage to it.</p> |
