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.

Abstract: Embodiments include a container with a leak resistant seal. The leak resistant seal provides access to the inside of the container when the leak resistant seal is open. The leak resistant seal includes first and second seal portions that are configured to be coupled together to close the container. A gap is arranged between ends of the first seal portion and the second seal portion, which provides an abutment that each of the ends of the first and second seal portions contact when the first seal portion is coupled to the second seal portion.

Abstract: A container includes an outside portion forming an external surface of the container, an inside portion forming an internal surface of the container, and a container seal arranged on the internal surface and configured to open and close the container for providing access to the inside portion. The container seal includes a male seal portion arranged on the internal surface of a first side of the container, a female seal portion arranged on the internal surface of a second side of the container, a gap between a first end of the male seal portion on the first side of the container and a second end of the female seal portion on the second side of the container, and at least one gap seal that is disposed within the gap, between the male seal portion and the female seal portion.
