  • Patent number: 4042143
    Abstract: A double seal container for perishable foods and the like, comprising a base having upstanding side walls attached thereto and forming a receptacle with a wide mouth opening. The side walls include a seat portion disposed adjacent to an upper free edge thereof and having a smooth, frusto-pyrmidal surface adapted for forming a tapered seal. A removable snap-fitting lid closes the receptacle opening and forms a first airtight seal for the container. A seal plug having a smooth frusto-pyrmidal surface is pressed wedgingly into the seat portion and the cooperating frusto-pyrmidal surfaces of the seat portion and seal plug engage each other thereby forming a second container seal therebetween. The lid detachably retains the seal plug and the receptacle in a sealed position and the seal plug is provided with a recessed inner body portion whereby the seal plug when separated from the remainder of the container forms a bowl particularly adapted for serving therein the container's contents.
