A hollow container having an open top is provided with a cap releasably secured thereto. The cap, in turn, includes an open top having an inwardly and downwardly extending lip surrounding the opening. A lid is positioned in the opening and includes a peripheral lip that extends upwardly and outwardly to engage the lip of the cap to form a liquid seal therebetween. A spring member is seated within an annular groove within the cap and contacts the lid to urge the lid upwardly toward the cap. A slight air gap is maintained between the lips; the force of liquid in the container pushing against the lid when the container is tilted causes the lips to engage and maintain a liquid seal therebetween.
