In one illustrative embodiment, the container is shaped as a bottle, having a body and neck, with a first aperture at the top of the neck. A flat bottom or base opposite the neck features at least one aperture, such as a traditional soda can opening with a scored section and a tab. In some embodiments, the bottom includes multiple apertures of different sizes, allowing for the selection of an aperture of desired size for a particular application. In some embodiments, the entire bottom may function as a removable lid.
