This invention relates to an endwall for a container having a panel portion surrounded by a substantially vertical wall portion which terminates into a narrow rim. The rim is connected to a sidewall of the container. The wall portion extends outward from the container and is adapted to be reformed inwardly into the container in a controlled manner by an external mechanism to reduce the volume thereof after the container has been filled and sealed. The invention also relates to a method of packaging a product in a container having a body opened at one end and closed at an opposite end by an endwall as described above. The method includes the steps of filling the container with a product and sealing the open end, thermally treating the filled and sealed container, and reforming the endwall inwardly into the container. The sequence of steps can be rearranged.

A method of packaging a product in a container having a sidewall open at one end and closed at an opposite end by a thin metal endwall, said endwall having a central panel portion surrounded by a substantially vertical wall portion projecting from said panel portion toward the inside of the container, said wall portion connected at its inner end to a relatively narrow rim radially outwardly surrounding said wall portion, with said rim connected to said sidewall, said method comprising the steps of: (a) filling said container with a product and sealing the open end thereof; and (b) reforming said endwall to move said central panel portion inwardly into said container in a controller manner to reduce the internal volume of said container by rolling at least one end of said substantially vertical wall portion to reduce the height of the wall portion.
