A container made of an elastomer such as silicone with an integrated leak resistant seal. The seal incorporates press-fit elements with sizes and shapes sufficient to provide a strong seal that resists leakage of liquids from inside the container. The seal is integrated into the container and requires no external clips or clasps. Additional features are provided to facilitate opening such as extended flaps for pulling the sides open, and asymmetric cavities for press-fit elements to reduce the initial opening force. The container itself may be of asymmetrical shape, such as trapezoidal, to provide a wide opening along with a strong seal.
