Reusable food transportation device

Abstract

The reusable food transportation device, or food transportation system, includes a single hub that connects to a collection of containers. The hub is circular and the food containers are angular wedges projecting horizontally outward from the hub. Each food container includes a vessel and a lid. During transportation the hub, formed from an upper section and a lower section, compresses each lid against its respective vessel to prevent spillage of the food contained within. When the device arrives at its destination the upper section and the lower section of the hub are separated from each other. This removes the compressive force holding the lid and the vessel in place. The user may then remove the containers as they see fit.

DETAILED DESCRIPTION

[0039] Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.

[0040] Referring to FIG. 1, a first isometric view of the food transportation system is shown.

[0041] The food transportation system 100 is shown formed from a hub no and multiple containers 180.

[0042] Referring to FIGS. 2 and 3, first and second isometric views of the hub of the food transportation system are shown.

[0043] The hub 110 is shown formed from hub upper section 112 with upper plate 114, upper cylinder 116, and upper rib 118.

[0044] Also shown is hub lower section 122 including lower plate 124.

[0045] To align the food containers 180 (see FIG. 1), also shown is lower rib 128.

[0046] The hub lower section 122 includes an upwardly projecting lower cylinder 126.

[0047] The hub 110 optionally includes a handle 150. An optional alignment opening 152 is an entrance to a hole that passes completely through the hub 110. This allows multiple hubs to be stacked, using a central rod to maintain alignment.

[0048] A central knob 154 with thumb depressions 156 helps the user to rotate the hub upper section 112 with respect to the hub lower section 122, allowing the user to engage and disengage the two sections from each other.

[0049] Referring to FIG. 4, a side and partially exploded view of the hub of the food transportation system is shown.

[0050] In this embodiment, the hub upper section 112 and hub lower section 122 engage and disengage with each other using a twist lock mechanism, or releasable locking mechanism 130.

[0051] The releasable locking mechanism 130 is formed from the upper cylinder 116 and lower cylinder 126, which slide together. A slot 132 guides and locks a pin 134, with final rotation causing locking of the pin 134 within the slot 132.

[0052] The releasable locking mechanism 130 has a locked position and an unlocked position.

[0053] In the locked position, the hub upper section 112 and hub lower section 122 are held together, compressing a food container 180 (see FIG. 5).

[0054] In the unlocked position, the hub upper section 112 and hub lower section 122 are disengaged from each other, allowing the user to remove the hub upper section 112, and correspondingly remove the food container 180 (see FIG. 5).

[0055] Referring to FIGS. 5 and 6, partially exploded side and isometric views of the hub and a single container of the food transportation system are shown.

[0056] To align the food containers 180 with the hub 110, the upper rib 118 and lower rib 128 interface with the lid groove 204 and vessel groove 206, respectively.

[0057] The combination of the upper rib 118 in lid groove 204, and/or the combination of the lower rib 128 and vessel groove 206, are referred to as an alignment rings. The alignment ring is considered the confluence of grooves and ribs, with a circular shape that aligns the hub 110 with the one or more food containers 180.

[0058] When the hub 110 is compressed against a food container 180, the food container 180 cannot move outward with respect to the hub 110. This prevents the food containers from disengaging from the hub 110. The vertical compression holds the food containers 180 closed and prevents rotation and dislodgement of the food container 180 with respect to the hub 110.

[0059] Each container 180 is formed from a lid 182 and vessel 184 that meet at a junction 186. The lid 182 and vessel 184 optionally include a hinge 188 that allows the user to rotate the lid 182 up and away from the vessel 184.

[0060] Referring to FIG. 7, an isometric view of the containers of the food transportation system is shown.

[0061] Each container 180 is divided into a main section 192 and a mating section 194.

[0062] Main section 192 is where the bulk of the food is held. Mating section 194 is the part interfaced with by the hub 110 (see FIG. 1).

[0063] The hub 110 passes through central hole 198, the space left in the center between any mounted containers 180.

[0064] Each container 180 occupies a container angle 190. Shown are a 60-degree container 220, a 120-degree container 224, and a 180-degree container 226.

[0065] The alignment ring, shown here as lid groove 204, is created by the combination of multiple containers 180 placed such that they form a complete circle.

[0066] Referring to FIGS. 8 and 9, second and third isometric views of the food transportation system are shown.

[0067] The food transportation system 100 is shown with fewer containers than maximum capacity. The compression of the hub 110 against the containers 180 holds the containers 180 in place, even with a section of the hub 110 left empty.

[0068] Referring to FIG. 10, a cross-section of the food transportation system is shown.

[0069] The hub 110 is shown holding food containers 180. The upper rib 118 interfaces with the lid groove 204. The lower rib 128 interfaces with the vessel groove 206.

[0070] The spring 135 is visible nested within the upper cylinder 116 and lower cylinder 126. The spring is compressed as the hub upper section 112 is pushed toward the hub lower section 122. When the release of a locking mechanism 130 (see FIG. 4), the spring 135 creates a popping action, pushing hub upper section 112 away from hub lower section 122.

[0071] In this cross-sectional view, it is apparent that the bottom of the food containers 180 shares the same plane as the bottom of the hub 110.

[0072] The result is that the food transportation system is stable and sturdy because the weight of the entire device is supported across the bottom of both the food containers and the hub.

[0073] The stacking groove 208 and stacking rib 209 interact with additional food transportation systems 100 placed above, or below, each other. The result of the interaction between the stacking grooves 208 and stacking ribs 209 is to align multiple food transportation systems 100, creating a common central axis.

[0074] By allowing the stacking groups 208 and stacking ribs 209 to interact with each other, the multiple systems 100 are aligned.

[0075] Referring to FIG. 11, an isometric view of a 90-degree container of the food transportation system is shown.

[0076] Container 180 is shown as a 90-degree container 222.

[0077] Referring to FIGS. 12 and 13, isometric views of the first and second embodiments of the containers of the food transportation system are shown.

[0078] Each container 180 includes a lid 182 and vessel 184 that meet at a junction 186. The main sections 192 are substantially identical across the first and second embodiments.

[0079] The difference between the two embodiments can be seen by comparing the mating sections 194.

[0080] The first embodiment, shown in FIG. 12, can store food in the mating section 194. In contrast, the second embodiment, shown in FIG. 13, does not store food within the mating section 194. Instead, the mating section 194 of the vessel 184 is moved upward. An optional retaining tab 196 is created to allow the user to grip the container 180 for efficient dispensing.

[0081] Referring to FIG. 14, a first isometric view of a second embodiment of the hub of the food transportation system is shown.

[0082] The hub 110 again includes a hub upper section 112, upper plate 114, hub lower section 122, upper groove 119, and lower groove 129. In the second embodiment of the hub, the hub upper and lower sections contain grooves as opposed to ribs.

[0083] Regarding the use of grooves or ribs, the hub and food container can each be formed with either grooves or ribs, so long as the opposing surface uses the opposite. For example, the food container can include upward-facing ribs and downward-facing grooves with the mating hub services having the opposite. Alternative arrangements that mix-and-match grooves and ribs are anticipated. The goal is alignment by mating a groove and a rib, without requiring the hub or the food container to have grooves or ribs specifically.

[0084] In this second embodiment, the hub upper section 112 attaches to the hub lower section 122 via a male-threaded protrusion 136 and a female-threaded recess 138.

[0085] The releasable locking mechanism 130 of the second embodiment is the combination of a male-threaded protrusion 136 and a female-threaded recess 138.

[0086] Referring to FIG. 15, a cross-section of the second embodiment hub and container of the food transportation system is shown.

[0087] The hub 110 is shown holding food container 180. The upper groove 119 interfaces with the lid rib 205. The lower groove 129 interfaces with the vessel rib 207.

[0088] The retaining tab 196 sits within the tab gap 140.

[0089] The releasable locking mechanism 130 of the second embodiment is the combination of a male-threaded protrusion 136 and a female-threaded recess 138.

[0090] In this cross-sectional view, it is apparent that the bottom of the food containers 180 shares the same plane as the bottom of the hub 110.

[0091] Again shown is hinge 188.

[0092] Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.

[0093] It is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction, and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely an exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
