Container and seal assembly

A container assembly comprising:

• a container and a seal ring configured to attach to the container in an attached configuration, wherein:
• the container comprises:
• a u-shaped crevice that is (i) internally located within the container, (ii) upwardly open toward a top opening of the container, and (iii) configured to engage with at least a portion of a lower seal structure of the seal ring;
• and0
• a crevice arm positioned radially inward from the u-shaped crevice, the crevice arm projecting from a sidewall of the container;
• the seal ring comprises:
• an outer sidewall comprising:
• an arcuate portion for interfacing with a corresponding semi-circular bead of a sidewall of a container in the attached configuration;
• an outer lip defining an annular channel having an upper closed end and a lower open end, the upper closed end being closer to the top of the container than the lower open end when the seal ring is in the attached configuration;
• and
• a seal ring protrusion for engaging with the semi-circular bead in the attached configuration, the seal ring protrusion opposite an undercut surface of the annular channel;
• an inner sidewall comprising a ring bead for engaging with a corresponding component on a container lid;
• a floor extending from a first intersection between the floor and the inner sidewall to a second intersection between the floor and the outer sidewall;
• the lower seal structure, wherein the lower seal structure is configured to engage with the corresponding u-shaped crevice on the container and comprises:
• a lower portion of the outer sidewall;
• a cavity defined by a bottom structure of the lower portion of the outer sidewall, wherein the cavity comprises:
• a first surface interfacing with a surface of the lower portion of the outer sidewall;
• a second surface forming a rounded transition to an underside of the bottom structure;
• and
• an upper interior surface extending between the first surface and the second surface,
• wherein the cavity has a radially innermost edge that is bounded by a bottom surface that extends along at least a portion of the floor;
• and
• a latch portion defined by the lower portion of the outer sidewall and the cavity;
• and
• when the seal ring is in the attached configuration:
• the cavity of the seal ring at least partially receives the crevice arm of the container and the u-shaped crevice of the container at least partially receives the latch portion of the seal ring to thereby form an interlocking seal between the container and the lower seal structure of the seal ring;
• and
• a radial axis parallel to a bottom of the container simultaneously intersects the cavity of the seal ring, the crevice arm of the container, the u-shaped crevice of the container, the latch portion of the seal ring, and the bottom surface of the seal ring.

A container comprising:

• a container body comprising a bottom, an uppermost end opposite the bottom and having a top opening, and an external wall extending from the bottom to the uppermost end and defining an interior cavity, the external wall comprising:
• an exterior wall surface;
• a container rim area proximate the uppermost end and comprising:
• a latch surface extending outwardly from the exterior wall surface;
• and
• a semi-circular bead formed by an interior wall surface;
• and
• a ledge area below the container rim area, the ledge area integrally formed with the external wall and defining a u-shaped crevice that is open in a generally upward direction toward the uppermost end of the container body and a container body arm for engaging with a corresponding lower seal structure of a seal ring, the container body arm extending at least partially in the generally upward direction toward the uppermost end of the container body;
• and
• the seal ring comprising:
• an outer sidewall comprising:
• an arcuate portion for interfacing with the semi-circular bead of the interior wall surface of the container body when the seal ring is in an attached configuration with respect to the container body;
• and
• a seal ring protrusion for engaging with the semi-circular bead in the attached configuration;
• an inner sidewall forming a seal structure for sealing the interior cavity of the container with a lid;
• and
• the lower seal structure for engaging with the u-shaped crevice on the container body and comprising:
• a cavity having a radially innermost edge that is bounded by a bottom surface extending from the radially innermost edge to the inner sidewall;
• and
• a latch portion defined by the outer sidewall and the cavity,
• wherein when the seal ring and the container body are in the attached configuration:
• the u-shaped crevice, the container body arm, the cavity, and the latch portion combine to form an interlocking seal between the container body and the lower seal structure of the seal ring;
• and
• each of (i) at least a portion of a radially outward wall surface of the u-shaped crevice, (ii) at least a portion of a radially inward wall surface of the u-shaped crevice, (iii) at least a portion of the container body arm, (iv) at least a portion of a radially outward wall surface of the cavity, (v) at least a portion of a radially inward wall surface of the cavity, (vi) at least a portion of the latch portion, and (viii) the bottom surface of the seal ring is intersected by a common radial axis that is perpendicular to a central vertical axis that passes through a center of the bottom of the container body, a center of the uppermost end of the container body, and a center of the seal ring.
