Abstract
The present disclosure relates generally to containers and container lids. In at least one embodiment, the disclosed containers and container lids include an improved seal structure that forms a liquid-tight seal. For example, in certain embodiments, the improved seal structure is included on a built-in ring around the rim of the container. In some embodiments, the improved seal structure is included on a separate container ring for attaching to a container. In these embodiments, the contents of the container may be poured out of the container such that virtually no excess content is trapped in-between seams.
Claims19
A container comprising:
- a seal structure configured to attach to a container body, the seal structure comprising:
- an inner sidewall comprising:
- a first seal surface having a vertical portion that extends in a direction substantially parallel to a central axis of the seal structure, the first seal surface being on a radially outward side of the inner sidewall;
- a second seal surface that is substantially flat and is on a radially inward side of the inner sidewall;
- and
- a ring bead integrally formed with the first seal surface at an intermediate position along the vertical portion of the first seal surface such that (i) a first vertical section of the first seal surface extends between the ring bead and a terminal end of the first seal surface and (ii) a second vertical section of the first seal surface extends between the ring bead and a floor of the seal structure, the ring bead extending radially outward from the first seal surface for engaging with a corresponding structure on a container lid;
- and
- an outer sidewall positioned radially outward from the inner sidewall, the outer sidewall comprising:
- an outer sidewall interior surface on a radially inward side of the outer sidewall;
- an outer sidewall exterior surface on a radially outward side of the outer sidewall, the outer sidewall exterior surface being substantially parallel to the first seal surface and terminating at a container bead;
- and
- a top surface of the container bead substantially perpendicular to the outer sidewall exterior surface;
- and
- the floor extending between the inner sidewall and the outer sidewall, whereby a channel structure is defined at least in part by the first seal surface of the inner sidewall, the outer sidewall interior surface of the outer sidewall, and the floor,
- wherein:
- the seal structure is configured to form a first seal with a container body and a second seal with the container lid when the container lid is in an attached configuration;
- the floor has an upper floor surface located within the channel structure and a lower floor surface opposite the upper floor surface;
- a first end of the lower floor surface transitions to a lower portion of the outer sidewall exterior surface via a first transition corner;
- a second end of the lower floor surface transitions to a lower portion of the second seal surface of the inner sidewall via a second transition corner;
- and
- wherein the lower floor surface is a continuous linear surface from the first transition corner to the second transition corner, wherein the first transition corner is configured to abut an inner surface of the container, and wherein the second transition corner defines an opening of the container.
