  • Publication number: 20200055642
    Abstract: A tamper-evident container includes a base and a lid with a closure portion includes a lip flange and a base flange. When the lid is secured to and closed over the base, the lid flange and the base flange rest adjacent to one another. The base flange includes perforations running along the length of the closure portion to divide the base flange into an outer region and an inner region. The lid flange is secured to the outer region of the base flange. When the lid is separated from the base, the lid flange tears away the outer region of the base flange with the assistance of the perforations on the base flange. When the lid is fully separated from the base, the lid flange carries the outer region of the base to avoid a separate member that needs to be thrown away.
