US Patent 11878834 Elastomeric container with integrated leak resistant seal and pressure shield

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.
