Benefits of technology

[0006] In view of the foregoing, the present invention provides containers whose covers can be stacked together in different ways. First, the covers can be stacked into an “aligned” stack. The aligned stack provides enough structural rigidity for bulk handling during manufacturing. Second, the covers can be stacked into a “locked” stack. The locked stack provides even more structural rigidity than does the aligned stack and is useful when storing unused covers. Another embodi

Embodiment Construction

[0039] Turning to the drawings, wherein like reference numerals refer to like elements, a first embodiment of the present invention is illustrated in FIGS. 1 through 5. A container 100 includes a flexible cover 102 sealingly engaged to a base 104. In the example of FIGS. 1 through 5, the container 100 is depicted as substantially square with rounded corners. In other embodiments of the present invention, the container 100 has other shapes such as rectangular, circular, or elliptical.

[0040] The container cover 102 can include at least one gripping tab 106 to facilitate removal of the cover 102 from the container base 104. In some embodiments, the gripping tab 106 includes one or more cross-ribs or a textured surface to improve a user's grip on the tab 106.

[0041] The container cover 102 illustrated in FIGS. 2 and 3 includes an engagement portion 200 that allows the cover 102 to engage with the engagement portion 200 of a second cover 102 to form a locked stack of covers 102. This lo...

Abstract

Containers having a cover and a base provide covers that may be locked together. In addition the container covers may be locked to a sidewall of the container base. The container cover includes a first closure portion and a cover engagement portion. The base includes a second closure portion and a base engagement portion. The first closure portion of the cover is sealingly engageable with the second closure portion of the base to define a sealed storage area. The cover engagement portion of a cover is releaseably lockable with the cover engagement portion of a second cover to form a locked cover stack. The cover engagement portion of the cover is also releaseably lockable with the base engagement portion of the base.

Description

[0001] This application is a continuation in part of International Application No, PCT / US 06 / 06263, filed Feb. 22, 2006, which claims benefit of U.S. Provisional Application No. 60 / 655,830, filed Feb. 23, 2005.FIELD OF THE INVENTION [0002] The present invention relates generally to containers, and, more particularly, to containers whose covers may be locked together and further whose covers may be locked to the bases of the containers. BACKGROUND OF THE INVENTION [0003] Rigid, thermoplastic food containers are generally known. Users often accumulate a large number of these containers in different sizes and shapes. When not in use, the containers are often stored haphazardly into drawers. In this case, the unused containers take up a great deal of room, and finding a matching base and cover in a disarranged drawer may be difficult. To avoid this, some users stack the containers in cabinets. While the bases of the containers usually nest and therefore take up less room than in a disor...
