## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to container storage systems and, more specifically, to a space saving container storage system wherein a plurality of containers having similar shapes but different sizes may fit one inside the other. Each container includes a lid which is releasably securable to both an open end of the container and a base of the container. Each lid has a unique color which corresponds to the color of the outer edge of the base of its matching container for easy storage thereof.
2. Description of the Prior Art
Storage containers, such as those manufactured by Tupperware®, frequently come in an assortment of shapes and sizes. However, the method of storing these containers is spatially inefficient and requires nesting containers one in side the other while separating each container from its corresponding lid. This separation of corresponding parts causes difficulty upon later user thereof.
Numerous other stackable containers exist in the prior art. Typical of these is U.S. Pat. No. 1,778,175 issued to E. E. Thune on Oct. 14, 1930.

Extending around the perimeter of the open end of the container 12 on a side of the wall opposite the pool is the open end lip 20. The open end lip 20 protrudes outwardly from the walls 16 and extends around the perimeter of the walls 16. The base lip 22 also protrudes outwardly from and extends about a perimeter of the wall adjacent to the base 18. The lid 14 may be releasably secured to at least one of the open end lip 20 and the base lip 22. The lid 14 preferably snaps onto the lip 20, 22 of the container 12. FIG. 9 shows the lid 33 releasably connected to the open end lip 20 of the container 12. Upon releasably securing the lid 33 to the base lip 22, the second container 32 is able to receive smaller containers within the pool thereof, as well as being positioned within the pool of a larger container thereof.
FIG. 10 is an enlarged perspective view of the third container 34 of the container storage system 10 of the present invention having a colored third lid 35 having a color different from the color of any other container of the set and corresponds with the color of the lip 22 extending around the base 18 thereof. As shown in FIGS. 1-5, each container includes the base 18 and the walls 16 which extend from and perpendicular to the base 18. The walls 16 and base 18 form the pool for receiving items to be stored in the container 12. Extending around the perimeter of the open end of the container 12 on a side of the wall opposite the pool is the open end lip 20. The open end lip 20 protrudes outwardly from the walls 16 and extends around the perimeter of the walls 16. The base lip 22 also protrudes outwardly from and extends about a perimeter of the wall adjacent to the base 18. The lid 14 may be releasably secured to at least one of the open end lip 20 and the base lip 22. The lid 14 preferably snaps onto the lip 20, 22 of the container 12. FIG. 10 shows the third lid 35 releasably connected to the open end lip 20 of the container 12. Upon releasably securing the lid 35 to the base lip 22, the third container 34 is able to receive smaller containers within the pool thereof, as well as being positioned within the pool of a larger container thereof.
FIG. 11 is an enlarged perspective view of the fourth container 36 of the container storage system 10 of the present invention having a colored fourth lid 37 having a color different form the color of any other container of the set and corresponds with the color of the lip 22 extending around the base 18 thereof. As shown in FIGS. 1-5, each container includes the base 18 and the walls 16 which extend from and perpendicular to the base 18. The walls 16 and base 18 form the pool for receiving items to be stored in the container 12. Extending around the perimeter of the open end of the container 12 on a side of the wall opposite the pool is the open end lip 20. The open end lip 20 protrudes outwardly from the walls 16 and extends around the perimeter of the walls 16. The base lip 22 also protrudes outwardly from and extends about a perimeter of the wall adjacent to the base 18. The lid 14 may be releasably secured to at least one of the open end lip 20 and the base lip 22. The lid 14 preferably snaps onto the lip 20, 22 of the container 12. FIG. 11 shows the fourth lid 37 releasably connected to the open end lip 20 of the container 12. Upon releasably securing the lid 37 to the base lip 22, the fourth container 36 is able to receive smaller containers within the pool thereof, as well as being positioned within the pool of a larger container thereof.
FIG. 12 is a cross-sectional view of the container storage system of the present invention taken along line 12-12 in FIG. 7. Shown herein is the first container 30 having the first lid releasably secured to the base of the first container 30. Positioned within the pool of the first container 30 is the second container 32 having the second lid 33 releasably secured to the base of the second container 32. Positioned within the pool of the second container 32 is the third container 34 having the third lid releasably secured to the base of the third container 34. The fourth container 36 having the fourth lid 37 releasably secured to the base of the fourth container 36 is positioned within the pool of the third container 34. By positioning the smaller container within the pool of the larger container, valuable storage space is saved. Additionally, the container storage system 10 of the present invention ensures that the lids which are specifically fit for their specific container will be stored in close proximity of the container thereby reducing the possibility of the lid being lost or misplaced.
As described with specific reference to FIGS. 6-12, each lid 31, 33, 35, 37 is color coated to match the base lip of the respective containers 12. The colors associated with both the lids and base lips of the containers can be any known color that would ensure that a user knows that the lid corresponds to a specific container. Preferably, the colors of each lid and base lip combination with in a set are different so a not to cause confusion as to which lid belongs with which container. Additionally, the container storage system of the present invention can include any number of containers each having similar shapes so that the containers may fit within a pool of a larger container thereby maintaining spatial efficiency while preventing the lids for each of the respective containers from being lost.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claims, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
