发明名称 Double sealed pizza package
摘要 A hermetic package for a food product having a first wall, a second wall and a receiving cavity. The first wall defines a first portion of the receiving cavity and a first flange surrounding the first portion of the receiving cavity. The second wall defines a second portion of the receiving cavity and a second flange surrounding the second portion of the receiving cavity. The second flange is preferably configured so that it is generally consistent with the configuration of the first flange. The first portion of the receiving cavity and the second portion of the receiving cavity are combined to form the receiving cavity by joining the first flange of the first wall to the second flange of the second wall to form an inner seal that is disposed outside of and surrounds the receiving cavity. The first flange of the first wall and the second flange of the second wall are further joined to one another to form an outer seal that is disposed outside of and at least partially surrounds the inner seal and the receiving cavity. The inner seal and the outer seal are configured so that they are substantially separated from one another by one or more gaps where the first flange is not joined to the second flange.
