Container and seal assembly

A container comprising:

• a body including an external wall, the body terminating at an open end including an integral ring having a seal structure around a circumference of the open end of the body, the seal structure including:
• an inner sidewall having a triangular peak, an inner seal surface, an outer seal surface, a seal ring notch disposed on the outer seal surface, and a ring bead protrusion on the inner seal surface,
• a floor connecting the inner sidewall and an outer sidewall, the floor sloping downward from the inner sidewall to the outer sidewall,
• a first u-shaped channel formed by the inner sidewall, the outer sidewall, and the floor, and
• a container bead disposed around the circumference of the container proximate the u-shaped channel, the container bead is a protrusion that extends outwardly from the outer sidewall and includes a top surface and a bottom surface that are parallel to a bottom surface of the body;
• and
• a container lid configured to be selectively coupled to the integral ring of the body, the container lid including
• a second u-shaped channel configured to receive the inner sidewall via a first lead-in feature and a second lead-in feature,
• a seal ring that engages the seal ring notch of the outer seal surface when the container lid is coupled to the body, and
• an indentation that forms an undercut and engages the ring bead protrusion to form a liquid-tight seal.
