Abstract: A container is made of an elastomer such as silicone with a leak resistant seal and pressure shield. The seal includes the elastomer and is configured to open and close the elastomeric container. The seal includes bottom and top press-fit elements, a bottom pressure shield is disposed between the bottom press-fit element and an inner volume of the container, and a top pressure shield is disposed between the top press-fit element and the inner volume. Top and bottom enclosures of the container define a center horizontal plane where the top and bottom enclosures meet. In cross section, a thickness of the top pressure shield continuously increases along an entire top pressure shield inner surface, and, in cross section, a thickness of the bottom pressure shield continuously decreases along an entire bottom pressure shield inner surface beneath the center horizontal plane.

Abstract: A container made of an elastomer such as silicone with a leak resistant seal and pressure shield. The seal incorporates press-fit elements sufficient to provide a strong seal that resists leakage of liquids from inside the container. The pressure shield increases leak resistance, is formed by material disposed on an inside of the container, and works by deflecting pressure away from the two leak resistant seal portions. The pressure shield includes a bottom pressure shield having an average thickness of at least 0.15 cm, and a top pressure shield having an average thickness of at least 0.15 cm.

Abstract: A container made of an elastomer such as silicone with an integrated leak resistant seal and pressure shield. 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. The pressure shield increases leak resistance by at least 300% and is formed by adding material to the inside of the container and not to the engaging portions of the seal and works by deflecting pressure away from the two leak resistant seal portions. 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.
