US Patent 11950679 Coupling seal of a container

A coupling seal of a container is provided. The coupling seal of a container includes a container with an interior reservoir. The interior reservoir is accessible via a rim about an aperture. The rim includes a number of protrusions. The protrusions are placed about the circumference of the rim so that a containment apparatus can mate with the rim. The containment apparatus includes a surface with a peripheral flange protruding therefrom. A number of arises are provided on the peripheral flange and are designed to mate with the protrusions of the rim. Rotation of the containment apparatus upon the rim causes the arises of the containment apparatus to mate with the protrusions of the rim, causing the container to seal.
