A container securing device includes a housing portion, with a cylindrical shape, the top of which is open, and which is intended to house a beverage container. A flap is positioned within a hole that is formed within a surrounding wall of the housing portion, and is installed so as to be capable of moving either out of the housing portion, or into the housing portion, in response to the container being inserted into, or extracted from, the housing portion. An impelling (biasing) component forces the flap toward the interior direction of the housing unit. The flap is capable of moving to a location that secures the container when the container is fully housed within the housing portion.
