Abstract: Embodiments include a method of manufacturing a container with a leak resistant seal. The method includes forming an elastomer or a plastic or any combination thereof into a container inside out by forming an outside portion of the container on an internal surface of the container before inverting the container and forming an inside portion of the container on an external surface of the container before inverting the container. In embodiments, the method includes forming or coupling a leak resistant seal on the external surface of the container before inverting the container. The leak resistant seal provides access to the inside portion of the container when the leak resistant seal is open after inverting the container and holds at least liquid internal to the container when applying an external force to the container without use of an external structure to keep the leak resistant seal closed after inverting the container.

Abstract: A container made of an elastomer such as silicone with an integrated leak resistant seal and pressure shield. Seal incorporates press-fit elements with sizes and shapes sufficient to provide a strong seal that resists leakage of liquids from inside the container, 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 may include a hole and be of asymmetrical shape, such as trapezoidal, to provide a wide opening along with a strong seal.
