Abstract

A container system includes first and second containers. Each of the containers includes a bottom wall and a plurality of sidewalls extending from the bottom wall. The sidewalls each include a first portion, a second portion, a lug between the first and second portions, with the lug extending substantially perpendicular relative to surfaces of the first and second portions. The sidewalls also each include a sealing rim including a surface that extends substantially perpendicular relative to a surface of the second portion. The second container is nestable in the first container with portions of the lugs of the second container resting on the surfaces of the sealing rims of the first container.

Claims

1. A container system comprising:

(A) a first container including;

(a) a bottom wall; and

(b) a plurality of sidewalls extending from the bottom wall, each of the sidewalls including (i) a first portion, (ii) a second portion, (iii) a lug between the first and second portions, with the lug extending substantially perpendicular relative to surfaces of the first and second portions, and (iv) a sealing rim including a surface that extends substantially perpendicular relative to a surface of the second portion; and

(B) a second container including;

(a) a bottom wall; and

(b) a plurality of sidewalls extending from the bottom wall, each of the sidewalls including (i) a first portion, (ii) a second portion, (iii) a lug between the first and second portions, with the lug extending substantially perpendicular relative to a surface of the first and second portions, and (iv) a rim including a surface that extends substantially perpendicular relative to a surface of the second portion,

wherein the second container is nestable in the first container with portions of the lugs of the second container resting on the surfaces of the sealing rims of the first container, and

wherein the sidewalls of the second container are spaced from the sidewalls of the first container when the second container is nested in the first container.

2. A container system according to claim 1, wherein the surfaces of the sealing rims of the first container that extend substantially perpendicular to the second portions are first surfaces, and the sealing rims of the first container further comprise second surfaces between the second portions and the first surfaces, with the second surfaces extending at an angle relative to the first surfaces and the second portions.

3. A container system according to claim 1, wherein the first portions of the sidewalls of the first container are angled relative to the second portions of the sidewalls of the first container.

4. A container system according to claim 1, wherein the first portions of the first container are angled relative to a line extending perpendicular to the bottom wall.

5. A container system according to claim 4, wherein the angle is about 3°

to about 8°

.

6. A container system according to claim 5, wherein the angle is about 4°

to about 5°

.

7. A container system according to claim 1, wherein the second portions of the sidewalls of the first container include two portions that are offset from each other.

8. A container system according to claim 1, further comprising:

(C) a third container including;

(a) a bottom wall; and

(b) a plurality of sidewalls extending from the bottom wall, each of the sidewalls including (i) a first portion, (ii) a second portion, (iii) a lug between the first and second portions, with the lug extending substantially perpendicular relative to surfaces of the first and second portions, and (iv) a rim including a surface that extends substantially perpendicular relative to a surface of the second portion,

wherein the third container is nestable in the second container with portions of the lugs of the third container resting on the surfaces of the sealing rims of the second container.

9. A container comprising:

(a) a bottom wall; and

(b) a plurality of sidewalls extending from the bottom wall, each of the sidewalls including (i) a first portion, (ii) a second portion, (iii) a lug between the first and second portions, with the lug extending substantially perpendicular relative to adjacent surfaces of the first and second portions, and (iv) a sealing rim including a surface that extends substantially perpendicular relative to the second portion, wherein the sidewalls are connected at corners of the container, and wherein a distance that the lugs extend from the adjacent surfaces of the first and second portions in regions of the corners of the container is greater than a distance that the lugs extend from the adjacent surfaces of the first and second portions in other regions of the container.

10. A container according to claim 9, wherein the shape of the container is selected from the group consisting of square and rectangular.

11. A container system comprising:

(A) a first container including;

(a) a bottom wall; and

(b) a sidewall extending from the bottom wall, the sidewall including (i) a first portion, (ii) a second portion, (iii) a lug between the first and second portions, with the lug extending substantially perpendicular relative to surfaces of the first and second portions, and (iv) a sealing rim including a surface that extends substantially perpendicular relative to a surface of the second portion; and

(B) a second container including;

(a) a bottom wall; and

(b) a sidewall extending from the bottom wall, the sidewall including (i) a first portion, (ii) a second portion, (iii) a lug between the first and second portions, with the lug extending substantially perpendicular relative to surfaces of the first and second portions, and (iv) a rim including a surface that extends substantially perpendicular relative to a surface of the second portion,

wherein the second container is nestable in the first container with a portion of the lug of the second container resting on the surface of the rim of the first container, and

wherein the sidewall of the second container is spaced from the sidewall of the first container when the second container is nested in the first container.

12. A container system according to claim 11, wherein the first and second containers have a shape selected from the group consisting of a round shape, a rectangular shape, and a square shape.

13. A container system according to claim 11, wherein the surface of the sealing rim of the first container that extends substantially perpendicular to the second portion is a first surface, and the sealing rim of the first container further comprises a second surface between the second portion and the first surface, with the second surface extending at an angle relative to the first surface and the second portion.

14. A container system according to claim 11, wherein the first portion of the first container is angled relative to a line extending perpendicular to the bottom wall.

15. A container system according to claim 14, wherein the angle is about 3°

to about 8°

.

16. A container system according to claim 15, wherein the angle is about 4°

to about 5°
