Container with nestable structure
The present disclosure relates generally to containers. In at least one embodiment, the disclosed containers include a nestable structure that can facilitate stacking while limiting reliance on satellite rings. For example, in certain embodiments, a container includes a nestable corner structure with a series of nestable portions. Thus, in these embodiments, more containers can be stacked together in a smaller space, such that shipping and manufacturing processes are more efficient and less costly than with traditional containers.
1. A container comprising:
a top comprising a top perimeter;
a bottom comprising a bottom surface and a bottom perimeter, the bottom perimeter;
a sidewall surface extending upwardly from the bottom perimeter to the top perimeter, the sidewall surface being located on an exterior of the container and being substantially smooth; and
a strengthening structure extending from the bottom perimeter to an upper portion of the container and comprising:
a first side edge along a first side of the strengthening structure, the first side edge being substantially parallel to the sidewall surface;
a second side edge along a second side of the strengthening structure, the second side edge being substantially parallel to the sidewall surface;
a first step surface extending from the sidewall surface inwardly to a first strengthening structure surface, the first step surface being substantially parallel to the bottom surface;
a second step surface extending from the first strengthening structure surface inwardly to a second strengthening structure surface, the second step surface being substantially parallel to the bottom surface; and
one or more ribs extending along an external surface of the strengthening structure, wherein one of the one or more ribs (i) extends vertically between the first step surface and the second step surface and (ii) comprises a rib overhang that extends to a lowermost height that is less than a height of the first step surface and a height of the second step surface, wherein all heights are determined relative to the bottom surface of the bottom of the container.
2. The container of claim 1 further comprising one or more interior ribs located on an interior surface of the strengthening structure and within an interior of the container.
3. The container of claim 1 , wherein the strengthening structure further comprises one or more additional strengthening structure surfaces along the first side edge and the second side edge.
4. The container of claim 3 , wherein a distance between the first side edge and second side edge is constant along the strengthening structure.
5. The container of claim 3 , wherein a distance between the first side edge and second side edge varies along the strengthening structure.
6. The container of claim 1 , wherein the bottom perimeter has a shape comprising four sides, each of the four sides being substantially straight.
7. The container of claim 1 , wherein the bottom perimeter has a substantially circular shape.
8. The container of claim 1 , wherein:
the upper portion of the container comprises at least two satellite rings located along an exterior perimeter of the upper portion, and
the one of the one or more ribs extends vertically between the at least two satellite rings.
9. The container of claim 8 , wherein the one of the one or more ribs extends vertically between an uppermost satellite ring of the at least two satellite rings and a rim structure located along the top perimeter.
10. The container of claim 1 , wherein:
the strengthening structure is a first strengthening structure,
the container further comprises a second strengthening structure, and
the sidewall surface extends from an edge of the first strengthening structure to an edge of the second strengthening structure.
11. The container of claim 10 , wherein the sidewall surface is substantially flat.
12. The container of claim 10 , wherein the sidewall surface is substantially convex.
13. A container comprising:
an interior bottom perimeter;
a top container edge;
a first sidewall section extending from the interior bottom perimeter to the top container edge, the first sidewall section having an exterior surface that is substantially smooth;
a second sidewall section extending from the interior bottom perimeter to the top container edge; and
a sidewall structure comprising two or more steps, the sidewall structure being disposed between the first sidewall section and the second sidewall section, each of the two or more steps comprising:
a first step surface extending from a first internal edge to a first external edge, the first step surface having a first uppermost height and a first lowermost height; and
a second step surface extending from a second internal edge to second external edge, the second step surface having a second uppermost height and a second lowermost height that are less than the first uppermost height and the first lowermost height, wherein all heights are determined relative to the interior bottom perimeter; and
one or more ribs extending vertically along an external surface of the sidewall structure, wherein one of the one or more ribs extends vertically from a location above one of the first or second step surfaces to a lowermost rib height that is less than the first lowermost height or the second lowermost height such that the one of the one or more ribs comprises a rib overhang across the first external edge or the second external edge.
14. The container of claim 13 , wherein:
the first step surface extends a first distance from the first sidewall section to the second sidewall section; and
the second step surface extends a second distance from the first sidewall section to the second sidewall section, the second distance being different from the first distance.
15. The container of claim 13 , wherein the first external edge of the first step surface comprises a first radius and the second external edge of the second step surface comprises a second radius that is equal to the first radius.
16. The container of claim 13 , wherein the interior bottom perimeter is substantially rectangular.
17. The container of claim 13 , wherein the interior bottom perimeter is substantially circular.
18. The container of claim 13 , wherein each of the two or more steps is recessed inward toward an interior of the container, relative to the first sidewall section and the second sidewall section.
19. The container of claim 18 , wherein:
the sidewall structure further comprises:
a first riser portion extending upwardly from the first external edge; and
a second riser portion extending upwardly from the second external edge, and the first riser portion and the second riser portion are both substantially concave.
