A retortable package comprising
- a container including a receptacle formed to include a product-storage region and a brim coupled to the receptacle and formed to include a brim aperture opening into the product-storage region formed in the receptacle and
- a lid including a brim seal, a sheet-support ring adhered to the brim seal and coupled to the brim to position a ring aperture formed in the sheet-support ring to open into the product-storage region and to trap the brim seal between the brim and the sheet-support ring to establish an endless sealed connection between the brim of the receptacle and the sheet-support ring of the lid, and a removable closure including a peelable membrane sheet coupled temporarily to a topside portion of the sheet-support ring to close the ring aperture and cooperate with the sheet-support ring and the brim seal to provide means for retaining product stored in the product-storage region in a sealed chamber during exposure of the container and lid to high package-sterilization and cooking temperatures until the peelable membrane sheet is separated from the topside portion of the sheet-support ring to open the ring aperture so that product can be discharged from the product-storage region in sequence through the brim aperture and the ring aperture.
A retortable package comprising
- a container and
- a lid mounted on the container to close a brim aperture opening into an interior region of the container, wherein the lid includes a removable closure including a membrane sheet and a pull tab coupled to the membrane sheet, a sheet-support ring configured to mount permanently on a brim of the container when the lid is mounted on the container, and a brim seal coupled to an underside of the sheet-support ring to move therewith and trapped between the sheet-support ring and the brim when the lid is mounted on the container, and wherein the membrane sheet is coupled temporarily to a topside portion of the sheet-support ring for removal therefrom to expose a ring aperture formed in the sheet-support ring and aligned with the brim aperture to open into the interior region of the container.
