This invention relates generally to storage containers and, more particularly, to a food storage container that is reusable and may be disassembled for washing and storage. The food storage container is ideal for carry-out pizza or storing pizza after removal from a traditional cardboard pizza box.
When dining out at a pizza restaurant or picking up pizza by carry-out, slices of pizza are typically brought home in a square or rectangular cardboard box. Recurring problems with this procedure include determining how to store the leftover pizza slices in the refrigerator and how to overcome grease soaking through the pizza box. Continued use of the pizza box, such as when storing pizza slices for several days, only exacerbates the problems described above.
Consumers may choose to utilize one or more plastic containers with sealable lids to store pizza slices in a refrigerator. Although assumably effective for their intended purposes, traditional plastic food storage containers introduce additional problems, such as not being configured to hold multiple slices or even an entire pizza, causing the buildup of significant condensation due to a lack of venting, and large containers not being easy to load in a dishwasher or to store in a cabinet.
Therefore, it would be desirable to have a reusable food pizza box specifically configured to store leftover or carry-out pizza. Further, it would be desirable to have a reusable food pizza box that provides ventilation to the contents while not allowing grease or moisture to leak from the container. In addition, it would be desirable to have a reusable food pizza box that may be quickly and easily assembled for use and disassembled for storage or cleaning.
A reusable food storage container according to a preferred embodiment of the present invention includes bottom and top members, each having first and second portions. Each bottom member first portion includes a bottom wall with opposed side walls and an end wall extending between the side walls and extending upwardly from the bottom wall. Each bottom member portion defines an open end opposite its respective outside end wall and an open top. The bottom member portions are selectively coupled together using a tab and channel structure. The top member portions each include a top wall having opposed end walls with an outer side wall connecting the end walls and extending downwardly from the top wall. Each top member portion defines an open interior side opposite its respective outside side wall and an open bottom. The top member portions are selectively connected using tab and channel structures. The top portion includes a circumference slightly larger than that of the bottom portion, enabling a nesting attachment.
The bottom walls of the bottom portions include an interior edge having a lip and groove structure, respectively, so as to form a moisture barrier when the bottom portions are selectively coupled together. In addition, the top member portions include at least one locking tab extending from an interior surface of the top wall that is displaced slightly from a respective top member portion end wall so as to form a slot configured to receive a portion of a respective bottom member end wall in a friction fit engagement. Accordingly, all portions are selectively and securely coupled together while still being easily disassembled for storage or cleaning.
Therefore, a general object of this invention is to provide a reusable food storage container that may be assembled and disassembled for storage and cleaning.
Another object of this invention is to provide a reusable food storage container, as aforesaid, that gently locks together multiple container portions for stability and strength.
Still another object of this invention is to provide a reusable food storage container, as aforesaid, in which the multiple container portions may be disassembled with mild pulling force.
Yet another object of this invention is to provide a reusable food storage container, as aforesaid, that is vented to diminish condensation buildup and that is sealed to eliminate leakage.

The first portion 62 includes a top wall 68, the first portion end walls 64 and side wall 66 extending downwardly from a peripheral edge thereof. The top wall 68 includes a generally planar configuration and an interior edge 69 opposite the outer side wall 66. Accordingly, the top member first portion 62 defines an open bottom and defines an open interior side at the interior edge 69 opposite the first portion outer side wall 66.
Similarly, the top member second portion 80 may include opposed end walls 84 and an outer side wall 86 extending between the opposed end walls 84. The second portion 80 includes a top wall 88, the second portion end walls 84 and side wall 86 extending downwardly from a peripheral edge thereof. The top wall 88 includes an interior edge 89 opposite the outer side wall 86. Accordingly, the top member second portion 80 defines an open bottom and defines an open interior side at the interior edge opposite the second portion outer side wall 86. The top member first portion end walls 64 are selectively and releasably coupled to corresponding top member second portion end walls 84 as will be described in more detail later. The top member second portion outer side wall 86 may also include a cutout or recess 90 to receive a user's finger and aid in separating the top and bottom members.
The top member 60 with the top member first portion 62 coupled to the top member second portion 80 includes a circumference, defined by the end walls and side wall of the top member first portion and the top member second portion, slightly larger than a circumference, defined by the end walls and side wall of the bottom member first portion and the bottom member second portion, when the bottom member first portion 22 is coupled to the bottom member second portion 40. Accordingly, the bottom member 20 may be nested in the top member 60 (
Each of the side walls 24 of the bottom member first portion 22 defines a channel 32 having an open end 34 in communication with and adjacent the open interior end. In other words each first portion channel open end 34 is in communication with the area outside the respective first portion side wall 24. The first portion channel 32 also includes a closed end 36 inside a respective first portion side wall 24.
Each of the side walls 44 of the bottom member second portion 40 includes a tab 54 having an elongate configuration connected to a free edge thereof and that extends away from the free edge (

More particularly, the top member first portion 62 may include a vent 70a. Alternatively, or in addition, the top member second portion 80 may include another vent 70b. A vent (not shown) may also be situated on one or more side or end walls. It is understood that the vent(s) may include a plurality of perforations although one or more slits or louvers may also be suitable.
In addition, the top member second portion 80 may include a tab 94 extending downwardly from the second portion top wall 88 (
The strength and stability of the present invention is increased by the configuration and orientation of the top member portions relative to the bottom member portions. Specifically, the tab/channel structures of the bottom member portions are perpendicular to the tab/channel structures of the top member portions as clearly shown in
In use, the bottom member first 22 and second 40 portions may be coupled together by aligning and inserting respective tabs 54 into respective channels 32. The lip/groove structures described above may provide a friction fit or even a gentle snap fit arrangement at the fully engaged configuration. Similarly, the top member first 62 and second 80 portions may be fitted together. Food items such as pizza may be situated on the bottom walls of the bottom member and the top member 60 positioned atop the bottom member 20 in a nested relationship. The vent(s) 79a, 79b described above allows the food to “breathe” and inhibits the buildup of excessive condensation inside the food storage container 10. When the food has been removed or consumed, the food storage container 10 may be disassembled for cleaning and storage. Specifically, the top member 60 may be removed and the first 62 and second 80 portions gently pulled apart. Likewise, the first 22 and second 40 portions of the bottom member 20 may be gently pulled apart. The individual portions may then be placed into a dishwasher or sink for cleaning and then conveniently stored in a kitchen cabinet until needed again. It is understood that each of the portions described herein are preferably constructed of a dishwasher suitable plastic material.
