DETAILED DESCRIPTION

The present invention is directed to a stackable container system.

FIG. 1 illustrates various views of an exemplary container 101, while FIG. 2 illustrates various views of exemplary container 101 with a lid 104 that can be used in the stackable container system of the present invention. As shown, container 101 includes threads 102 around the opening for screwing on a lid 104. Other means for attaching a lid 104 to a container 101 could equally be used as is known in the art.

In some embodiments of the invention, to interconnect containers, a container is attached to the lid of another container using a bayonet mount. For example, as shown in FIG. 1, the bottom of container 101 is configured with a male portion 103a of a bayonet mount that connects with a female portion 103b of the bayonet mount that is formed on the top of lid 104. Using the bayonet mount, a container 101 can be interconnected with a lid 104 thereby allowing multiple containers to be interconnected in a stack. Specifically, male portion 103a is twisted into female portion 103b where it is held in place within a pocket formed in female portion 103b.

As shown in FIG. 3, the stackable container system of the present invention includes a plurality of containers 101 and a plurality of lids 104 that are each configured similarly to allow any of the containers 101 to be mounted to any of the lids 104 using the bayonet mount. As shown, each container 101 has been sealed by threading on a lid 104. Further, the top container 101 has been mounted to the lid 104 of the second container 101 by connecting male portion 103a of the top container 101 with female portion 103b of the lid 104 of the second container 101. The middle container 101 is mounted to the lid 104 of the bottom container 101 in the same manner.

As shown in FIG. 4, in some embodiments, the stackable container system can include a handle 105. The bottom of handle 105 (not shown) is also configured with a male portion 103a of a bayonet mount to enable handle 105 to be mounted to any of the lids. FIGS. 5 and 6 illustrate the stackable container system of FIG. 3 with the addition of handle 105. As can be seen, by mounting handle 105 to the stack of containers 101, the portability of the stack is increased. Further, because handle 105 can be mounted to any of the lids 104, the order in which the containers 101 are stacked is not important. Although a stack of three containers 101 is shown in FIG. 5, handle 105 can be attached to a stack of one or more containers 101 as desired. Also, as shown in FIG. 6, the stackable container system of the present invention can be of various sizes, and can be comprised of various numbers of containers 101 and lids 104.

In some embodiments, a stackable container system can include a storage container for storing a stack of interlocked containers. FIG. 7, for example, illustrates an exemplary stackable container system where a beverage bottle 106 is used as the storage container. As shown, the containers 101 and lids 104 of the stackable container system are sized so that when interlocked, the stack fits within beverage bottle 106.

The stackable container system of the present invention provides various advantages. For example, a user can use the stackable container system to separately store, in containers 101, multiple ingredients that are to be later mixed together within beverage bottle 106 (e.g. with water or another liquid).

Alternatively, containers 101 can be used to separately store various ingredients for a meal (e.g. lettuce, croutons, and dressing for a salad) that can later be mixed (e.g. in one of containers 101).

In some cases, it may be desirable to keep certain contents of containers 101 cool or warm. To facilitate cooling or warming such contents, in some embodiments, lids 104 can be configured with a component that may be heated or cooled. In some embodiments, the component can be removable from the lid 104. In other embodiments, the entire lid 104 can be heated and cooled.

Lids 104 can also be configured with an insulated layer along the top of the lid that will minimize the amount of heat or cold that escapes upwardly into another container. In other words, lids 104 can be configured to retain as much heat or cold from the lid (or component of the lid) within the container to maximize the heating or cooling to the contents of the container. In such embodiments where lids 104 include an insulated layer, a lid 104 of one container 101 could be heated while a lid 104 of another container 101 could be cooled depending on the desired effect on the contents of the respective containers in a stack.

In some embodiments, as shown in FIG. 8, the stackable container system of the present invention can include a mixing whisk 107. Mixing whisk 107 can be compressible to allow it to be compressed and stored within any of containers 101.

Mixing whisk 107 can be used to facilitate the mixing of ingredients within a storage container such as beverage bottle 106. For example, mixing whisk 107 can be compressed and stored within one of containers 101 with the contents of the container. The containers 101 of the system can then be interlocked in a stack and stored within beverage bottle 106. At a later time, the containers 101 can be removed from beverage bottle 106, and their contents, including mixing whisk 107, can be added to beverage bottle 106. Water or another liquid can be added to beverage bottle 106 if necessary. Finally, beverage bottle 106 can be shaken to mix the contents. The presence of mixing whisk 107 in beverage bottle 106 facilitates the mixing of the contents within beverage bottle 106.

FIG. 9 illustrates another embodiment of a stackable container system in which at least one of the lids 104 includes an opening 150. Opening 150 can be generally circular as shown, or can be of other shapes and/or sizes. Opening 150 can facilitate the pouring of contents (e.g. powder contents such as baby formula, granular contents such as cereals, liquid contents such as salad dressing, etc.) from a container 101 without removing lid 104. In a particular embodiment, opening 150 can be sized to fit within an opening of a baby bottle to facilitate the pouring of baby formula from a container 101 into a baby bottle.

In such embodiments, handle 105 can be configured with a sealing portion 151 to secure opening 150 when the handle is attached to the lid 104. In some embodiments, a separate lid (rather than or in addition to a handle 105) can be included to secure opening 150. For example, a lid that is configured similar to handle 105, but without the handle portion, can be attached to lid 104. In some embodiments, the bottom of at least one of the containers 101 can also be configured to secure opening 150 when the container is attached to the top of the lid 104 having the opening 150.

For example, as shown in FIG. 10, a lid 104 having an opening 150 can be used on a container 101 in a stack. In some embodiments, where only the handle (or other lid or closure configured to be attached to lid 104) is configured with sealing portion 151, the lid 104 having the opening 150 can be used as the topmost container in the stack. However, in embodiments where at least one of the containers 101 is configured on the bottom with a sealing portion 151 (not shown), the lid 104 having the opening 150 can be used on a container 101 in a layer other than the topmost layer of the stack by securing the opening 150 by attaching a container 101 having a sealing portion 151 to the top of the lid 104. In this manner, more than one lid 104 having an opening 150 can be used within a single stack of containers.

In conclusion, embodiments of the present invention comprise a stackable container system in which multiple containers can be interlocked using lids. This interlocking can be achieved using a bayonet mount formed on the top of each lid and the bottom of each container to allow any lid to be used on any container. A handle may also be configured with a bayonet mount for connecting the handle to any of the lids.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
