Container and Seal Assembly
The present disclosure relates generally to container systems comprising a container, a container ring, and a container lid. In one or more embodiments, the disclosed container systems use novel designs to provide a liquid-tight seal without the use of gaskets or adhesives. For example, in several embodiments, the container attaches to the container ring, and the container ring attaches to the container lid via a snap-fit assembly to facilitate reduced seams and increased sealing capability without the use of adhesives or additional sealing materials or components.
1 . A container assembly, comprising:
a container comprising:
a bottom surface; and
at least one sidewall circumscribing the bottom surface, wherein the at least one sidewall extends in a vertical direction from the bottom surface to an upper end thereby forming a cavity, the upper end comprising an attachment portion and a latch tab extending from the attachment portion in a radial direction;
a ring comprising:
a container latch channel for at least partially receiving the attachment portion of the container, wherein the container latch channel comprises an outer container latch channel (CLC) side, an inner CLC side, and a top CLC side;
a lid latch for engaging a lid, the lid latch comprising an inner lid latch side, a distal lid latch edge, and an outer lid latch side; and
a bottom wall extending between the inner CLC side and the outer lid latch side, wherein at least the inner CLC side, the bottom wall, and the outer lid latch side form a lid latch channel; and
the lid comprising:
a ring latch channel for at least partially receiving the lid latch of the ring,
wherein the latch tab is configured to fold downwardly when the container latch channel at least partially receives the sidewall.
2 . The container assembly of claim 1 , wherein the container latch channel comprises a CLC protrusion extending from the top CLC side into the container latch channel, the CLC protrusion for engaging the upper end of the container.
3 . The container assembly of claim 2 , wherein the CLC protrusion is substantially rectangular in shape.
4 . The container assembly of claim 1 , wherein the outer CLC side comprises one or more latch surfaces comprising:
a sloped surface extending in a sloped direction into the container latch channel.
5 . The container assembly of claim 4 , wherein the sloped surface forms at least part of a latch protrusion for engaging latch tab.
6 . The container assembly of claim 5 , wherein the latch protrusion has a substantially trapezoidal cross-sectional shape.
7 . The container assembly of claim 1 , wherein the ring further comprises an underside surface, wherein an edge between the inner CLC side and the underside surface is rounded or chamfered.
8 . The container assembly of claim 1 , wherein the bottom surface is substantially round.
9 . The container assembly of claim 1 , wherein a thickness of the at least one sidewall of the container is less than a width of the container latch channel.
10 . The container assembly of claim 1 , wherein the container is a first single component, the ring is a second single component, and the lid is a third single component.
11 . The container assembly of claim 1 , wherein attachment of the ring to the container forms a liquid-tight seal between the ring and the container.
12 . The container assembly of claim 1 , wherein attachment of the lid to the ring forms a liquid-tight seal between the lid and the ring.
13 . A system for sealing a container, comprising:
a ring for engaging the container, the ring comprising:
a container latch channel for accepting a portion of the container;
a lid latch for engaging with a lid, the lid latch comprising an inner lid latch side and an outer lid latch side, wherein at least a portion of the lid latch extends in a radial direction; and
a bottom wall extending between an inner wall of the container latch channel and the lid latch, wherein at least the inner wall of the container latch channel, the bottom wall, and the lid latch form a lid latch channel; and
the lid comprising:
a ring latch channel for at least partially receiving the lid latch of the ring, wherein the ring latch channel comprises an inner ring latch sidewall, an outer ring latch sidewall, and a top ring latch surface, wherein a width of the inner ring latch sidewall increases from a first diameter at a bottom of the inner ring latch sidewall to second diameter at a latch notch and decreases from the second diameter to a third diameter proximate the top ring latch surface.
14 . The system of claim 13 , wherein an upper portion of the outer lid latch side is substantially convex.
15 . The system of claim 13 , wherein the top ring latch surface is substantially rounded.
16 . The system of claim 15 , wherein the radial direction is radially outward.
17 . The system of claim 13 , wherein the inner ring latch sidewall comprises a ridged surface.
18 . The system of claim 13 , wherein the ring further comprises:
a ring bead protrusion on the outer lid latch side, wherein the ring bead protrusion extends into the lid latch channel.
19 . The system of claim 18 , wherein the ring bead protrusion has a substantially trapezoidal cross-sectional shape.
20 . The system of claim 19 , wherein the inner ring latch sidewall comprises a recess for engaging the ring bead protrusion.
21 . The system of claim 13 , wherein the outer ring latch sidewall comprises a latch protrusion for engaging the ring latch channel.
