1. A process for coupling a lid to a brim of a container to close an opening into an interior product-storage region formed in the container, the process comprising the steps of providing a lid having an elastic top wall made of an elastic material and a container having an annular brim arranged to surround an opening into an interior product-storage region formed in the container, wherein the annular brim includes an inner peripheral surface bounding the opening, an outer peripheral surface surrounding the inner peripheral surface, and an upwardly facing surface lying between and interconnecting the inner and outer peripheral surfaces,moving the elastic top wall of the lid downwardly toward the annular brim of the container to cause a radially inner portion of the lid to contact the inner peripheral surface of the annular brim and to locate any spilled product extant on the upwardly facing surface of the annular brim under a downwardly facing surface of the elastic top wall of the lid,stretching the elastic top wall of the lid in radially outward directions relative to the radially inner portion of the lid during further downward movement of the lid relative to the brim of the container to move substantially all of the spilled product extant on the upwardly facing surface of the annular brim in a radially outward direction away from the interior product-storage region and into a radially outer space provided between the lid and the outer peripheral surface of the annular brim to cause substantially all of the upwardly facing surface of the annular brim to be free of spilled product and to mate with a confronting companion surface of the downwardly facing surface of the elastic top wall of the lid therebetween so that substantially all of the spilled product formerly extant on the upwardly facing surface of the annular brim is wiped away, andheating the elastic top wall of the lid to establish a chemical-bond sealing connection between the elastic top wall of the lid and the upwardly facing surface of the annular brim of the container, wherein heat in excess of a selected temperature is applied to the elastic top wall of the lid during the heating step to cause any residual spilled product located on the upwardly annular brim in a space provided between the elastic top wall of the lid and the annular brim of the container after the stretching step to be gasified and pass as a gas from the space through the elastic top wall of the lid into the surroundings so that no spilled product remains on the annular brim of the container. 2. A process for coupling a lid to a brim of a container to close an opening into an interior product-storage region formed in the container, the process comprising the steps of providing a lid having an elastic top wall made of an elastic material and a container having an annular brim arranged to surround an opening into an interior product-storage region formed in the container, wherein the annular brim includes an inner peripheral surface bounding the opening, an outer peripheral surface surrounding the inner peripheral surface, and an upwardly facing surface lying between and interconnecting the inner and outer peripheral surfaces,moving the elastic top wall of the lid downwardly toward the annular brim of the container to cause a radially inner portion of the lid to contact the inner peripheral surface of the annular brim and to locate any spilled product extant on the upwardly facing surface of the annular brim under a downwardly facing surface of the elastic top wall of the lid, andstretching the elastic top wall of the lid in radially outward directions relative to the radially inner portion of the lid during further downward movement of the lid relative to the brim of the container to move substantially all of the spilled product extant on the upwardly facing surface of the annular brim in a radially outward direction away from the interior product-storage region and into a radially outer space provided between the lid and the outer peripheral surface of the annular brim to cause substantially all of the upwardly facing surface of the annular brim to be free of spilled product and to mate with a confronting companion surface of the downwardly facing surface of the elastic top wall of the lid therebetween so that substantially all of the spilled product formerly extant on the upwardly facing surface of the annular brim is wiped away, wherein the lid includes an inner rim providing the radially inner portion and outer rim arranged to surround the inner rim, the elastic top wall is arranged to interconnect the inner and outer rims of the lid the outer rim of the lid is arranged to surround the outer peripheral surface of the brim, and the inner rim is arranged to mate with the inner peripheral surface of the annular brim to locate a central plate included in the lid and coupled to the inner rim in the interior product-storage region formed in the container to close the opening into the interior product-storage region and limit movement of the inner rim of the lid relative to the annular brim during the stretching step. 3. The process of claim 2, wherein the inner peripheral surface of the annular brim has an annular convex rounded shape and the lid is deformed during the stretching step to mate with and move on the inner peripheral surface of the annular brim without piercing the lid as the lid continues to move downwardly relative to the container. 4. The process of claim 3, wherein the inner peripheral surface of the annular brim includes a lower segment coupled to a side wall of the container and an upper segment arranged to interconnect the upwardly facing surface and the lower segment, the upper segment has an annular convex rounded shape, and the lower segment has an annular shape. 5. The process of claim 2, further comprising the step of heating the elastic top wall of the lid after the stretching step and wherein the inner surface of the elastic top wall of the lid is configured to provide means for chemically bonding with the upwardly facing surface of the annular brim during the heating step, separating from the upwardly facing surface of the annular brim in response to application of an external peeling force to the membrane sheet to disengage the lid from the annular brim of the container, and mating with the upwardly facing surface of the annular brim of the container to close the opening into the interior product-storage region formed in the container when the lid is coupled to the container by a consumer so that any product stored in the interior product-storage region is retained in a sealed chamber defined by the container and the lid. 6. The process of claim 2, wherein the lid includes a brim-mount frame coupled to the annular brim and formed to include the elastic top wall, the brim-mount frame is also formed to include an inner rim coupled to an inner edge of the elastic top wall and configured to provide the radially inner portion and arranged to engage the inner peripheral surface of the annular brim and extend downwardly into the interior product-storage region formed in the container, and the brim-mount frame also includes an outer rim coupled to an outer edge of the elastic top wall and arranged to surround the inner rim to engage the outer peripheral surface of the annular brim. 7. The process of claim 6, wherein the lid further includes a cover foundation coupled to the inner rim of the frame and arranged to overlie the interior product-storage region of the container and a cover coupled to the cover foundation to close the opening into the interior product-storage region. 8. The process of claim 7, wherein the cover is coupled permanently to the cover foundation. 9. The process of claim 7, wherein frame, cover foundation, and cover cooperate to form a monolithic component. 10. The process of claim 2, wherein the lid further includes an outer rim surrounding the annular brim and an inner rim surrounded by the outer rim and arranged to lie in spaced apart relation to the outer rim, the inner rim is formed to include the radially inner portion, and the elastic top wall of the lid is arranged to interconnect the outer and inner rims. 11. The process of claim 10, wherein the lid further includes an annular lid-retention lip coupled to the outer rim and arranged to extend radially inwardly under the annular brim to anchor the frame mechanically to the annular brim of the container. 12. The process of claim 1, wherein the inner peripheral surface of the annular brim has an annular convex rounded shape and the lid is deformed during the stretching step to mate with and move on the inner peripheral surface of the annular brim without piercing the lid as the lid continues to move downwardly relative to the container. 13.
