Description

BACKGROUND OF THE INVENTION

Field of the Invention

One or more embodiments of the present invention relate to a takeout food container and more particularly, to a portable, disposable (one-time use) takeout food container that also functions as a table-tray.

Description of Related Art

Conventional food delivery and takeout containers are well known and have been in use for a number of years. Regrettably, most are only containers, requiring consumers to place the container on a table prior to consumption of food. Others are extremely complex to manufacture, and require too many pieces to assemble. Still others require additional containers to be used with the food delivery and takeout container. Yet others require too many cumbersome steps to operate by a consumer.

Accordingly, in light of the current state of the art and the drawbacks to current food delivery and takeout containers mentioned above, a need exists for a takeout food container that would be portable, disposable, and have a compact, small form factor for storage prior to its use.

Further, a need exists for a takeout food container that would be simple to manufacture, would not require too many pieces for assembly, would be easy to assemble, and easy to operate by a consumer.

Still further, a need exists for a takeout food container that would not require additionally (auxiliary containers) to deliver food within and for proper use (for example, to prevent leakage of food material).

Additionally, a need exists for a takeout food container that may be used as a table-tray for consumption of food or, alternatively, used as an elevated table-tray for a more convenient consumption of food.

FIGS. 1A to 1R are non-limiting, exemplary illustrations of a takeout food container, progressively illustrating non-limiting, exemplary methods of opening and closing the takeout container in accordance with one or more embodiments of the present invention. As illustrated, the fully assembled takeout food container 100 may be stacked on top of one another for storage or transport, and distributed one by one.

Takeout food container 100 is comprised of a tray 102, and a first sleeve cover 104 and a second sleeve cover 106 that when in closed position, cover tray 102 as shown in FIGS. 1A to 1R. First sleeve cover 104 and second sleeve cover 106 are identical.

When first sleeve cover 104 and second sleeve cover 106 are fully extended (pulled) to an open position and oriented perpendicular to a longitudinal axis 108 (FIG. 1P) of tray 102, first sleeve cover 104 and second sleeve cover 106 engage tray 102 to support tray 102 at an elevated position, functioning as serving tray legs to form a stable table-tray (FIGS. 1P and 1Q).

Referring to FIGS. 1D and IE, to open takeout food container 100, utensils 110 such as a pair of chopsticks may be pulled out of a set of utensil holders 112 of takeout food container 100. Thereafter, users may simply pull or slide out one of the sleeve covers 104 or 106 (e.g., first sleeve cover 104) laterally in the direction shown by arrow 114 in FIG. 1F to halfway open container and partially access content of tray 102.

Users may continue to slide out first sleeve cover 104 to open position while tilting it (as shown by arrow 116 in FIG. 1G-1) so that sleeve cover 104 or 106 is oriented perpendicular a longitudinal axis of tray 102 as sleeve cover 104 or 106 is eventually moved to a fully open position (FIGS. 1G-2 to 1L).

As first sleeve cover 104 is moved to open position and tilted, interior facing side 118 of top side 120 of sleeve cover continues to remain engaged (touches) top edge 122 of first transvers side 144 of tray 102.

As detailed, top edge 122 of first transverse side 144 of tray 102 is caught by an interlock mechanism (e.g., flap) 126 (detailed below) of first sleeve cover 114 as it is tilted and hence, tray 102 interlocks with first sleeve cover 114.

Additional movement of sleeve covers 104 and 106 is prevented due to bottom side 128 (FIG. 1L) of tray 102 resting on supporting edges 130 of sleeve covers 104 and 106. The same operations may be performed for second sleeve cover 106 as it is identical to first sleeve cover 104. In other words, an exterior bottom side 128 of tray 102 rests on supporting edge 130 of first and second sleeve covers 104 and 106 when tray 102 is interlocked with interlock mechanism 126 of first and the second sleeve covers 104 and 106.

As another alternative method shown in FIGS. 1M to 1R, both first and second sleeve covers 104 and 106 may be moved and tilted concurrently as shown, until both top edges 122 of transverse sides 144 and 146 of tray 102 are caught by respective interlock mechanisms 126 of first and the second sleeve covers 104 and 106. As yet another alternative option, first and the second sleeve covers 104 and 106 may simply be moved to an open position and set aside as shown in FIG. 1R.

FIGS. 2A to 2K are non-limiting, exemplary illustrations of the various views of the components that constitute a takeout food container as exemplarily shown in FIGS. 1A to 1R in accordance with one or more embodiments of the present invention. The takeout food container shown in FIGS. 2A to 2K is similar to the takeout food container shown in FIGS. 1A to 1R but it includes additional optional features that are further described in detail below.

As illustrated in FIGS. 2A and 2B, takeout food container 100 may comprise of a tray 102 in a form of a rectangular open top box that includes a base 134 having an interior (or top) side 136 (FIG. 2A), an exterior (bottom) side 128 (FIG. 2B).

Tray 102 further includes a first longitudinal side 140, a second longitudinal side 142 identical to first longitudinal side 140, a first transverse side 144, and a second transvers side 146 identical to first transverse side 144. Tray 102 further includes edge slits that function as interlocking recessed slots 148 (optionally, one or more per side) for receiving interlocking projections 204 of one or more compartmentalizing pieces 202. Tray 102 in FIG. 2A is shown with compartmentalizing pieces removed for clarity.

As further illustrated, tray 102 may optionally include an optional first elongated opening 150 near first transverse side 144 and an optional second elongated opening 152 near second transvers side 146.

Optional first and second elongated openings 150 and 152 are identical, and are oriented longitudinally (along their longitudinal axis 154) parallel first and second transverse sides 144 and 146 of tray 102. As detailed below, first and second elongated openings 152 and 154 function as interlocking recesses to interlock with optional first and second interlocking projections 168 and 170 of first and second sleeve covers 104 and 106.

As illustrated in FIGS. 2C to 2I, takeout food container 100 may comprise of sleeve covers 104 and 106. First sleeve cover 104 is identical to second sleeve cover 106, forming a first support and a second support that enable leveled elevation of tray 102 to form a stable table-tray.

First and second sleeve covers 104 and 106 include an interior cavity 156 defined by a top side 120, a bottom side 158, sleeve base 160, sleeve base support 380, and first and second identical lateral sides 162 and 164.

Top side 120 of first and the second sleeve covers 104 and 106 has sufficient expanse to cover half an area of tray 102. Lateral sides 162 and164 of sleeve covers 104 and 106 partially overlap a longitudinal (or length) sides 140 and 142 of tray 102, with lateral sides 162 and 164 having extending lateral portions 172 (further detailed below).

Bottom side 158 of sleeves covers 104 and 106 cover over exterior bottom side 128 of tray 128, with an open side that defines cavity 156 that receives tray 102. Bottom side 158 includes an exterior bottom side portion 384 and an interior facing bottom side portion 386.

Closed sides (i.e., sleeve base support) 380 of sleeve covers 104 and 106 engages transverse (or width) sides 144 and 146 of tray 102.

As further detailed below, exterior facing side 166 of top side 120 of first and second sleeve covers 104 and 106 includes utensil holders 112 for keeping utensils 110, with utensils 110 functioning as a handle for takeout food container 100 when maintained by utensil holder 112.

As best shown in FIGS. 1K, 2C, 2D, 2J, and 2K, utensil holder 112 is comprised of an exterior cutout 174 from an exterior facing side 166 of first and the second sleeve covers 104, 106, forming an external flap 176. External flap 176 itself may include a cutout 178, forming an opening 180. Optionally, as best shown in FIG. 1K, cutout 178 may be a partial cutout where it may retain an internal flap 182 associated with opening 180. As illustrated, flap 176 is bent outward at its cantilever edge 192 from exterior facing side 166 of top side 120

Utensil 110 is inserted through opening 180, and the optional internal flap 182 associated with opening 180 may be used to further frictionally secure utensil 110 inserted within opening 180, preventing utensil 110 from sliding out of opening 180.

First and the second sleeve covers 104 and 106 include an interlock mechanism 126 that interlocks with an interlocking edge of first and the second sleeve covers 104 and 106 for assembly of first and the second sleeve covers 104 and 106 (further detailed below). Interlock mechanism 126 further interlocks with lateral sides 144 and 146 of the tray 102 for interlocking first and the second sleeve covers 104 and 106 with tray 102.

As best illustrated in FIGS. 2J and 2K, interlock mechanism 126 is comprised of a cutout 186 from top side 120 of first and the second sleeve covers 104 and 106, forming a semi-circular flap 188. Flap 188 is bent inwardly at its cantilever edge 190 from exterior facing side 166 of top side 120 to interior facing side 118 of top side 120.

Flap 188 overlaps an interlocking edge 184 of secondary interior facing top side support 400 first and the second sleeve covers 104 and 106 (when assembled) and overlaps lateral side 144 and 146 of tray 102 for table-tray position.

As shown in FIGS. 1P, 1Q, and 2G, interlock mechanism 126 is located at a distance 194 below a top free edge 196 of first and second sleeve covers 104 and 106 at a distance equal to or greater than a height 198 of a side of tray 102, thus lowering an overall center of gravity of the table-tray when tray 102 is interlocked with first and second sleeve covers 104 and 106. This arrangement provides stability and also, the extended height 194 above interlock mechanism 126 of sleeves 104 and 106 function as shield to prevent food from splashing out laterally.

Extended lateral portions 172 of lateral sides 162 and 164 of first and second sleeve covers 104 and 106 engage longitudinal sides 140 and 142 of tray 102 to thereby prevent tray from in-plane motion or lateral twisting when in tray-table position. As best shown in FIG. 2F, the extended lateral portions 172 have free edge.358 that are sloped and taper from supporting edge 130 towards top free edge 196, ending below top free edge 196 at a distance 200, which may optionally equal to ¼ the distance from interlocking edge 184 to top free edge 196.

Top edge 130 of bottom side 158 may optionally include an extended flange 168/170 that form optional first and second interlocking projections 168 and 170 of respective first and second sleeve covers 104 and 106, which may interlock with optional first and second elongated openings 150 and 152.

FIG. 3 is a non-limiting, exemplary illustration of the various pieces that may be used to assemble takeout food containers shown in FIGS. 1A to 2K in accordance with one or more embodiments of the present invention. Any additional optional features in takeout food container shown in FIGS. 2A to 2K are further detailed in relation to FIGS. 7A to 7D-4.

As illustrated, takeout food container 100 is comprised of a tray piece 206, sleeve cover pieces 208 and 210 (that are identical), and optional divider pieces (compartmentation pieces or inserts) 212, and two identical divider pieces 288.

More specifically, takeout food container 100 includes tray piece 206, which is comprised of a first flat, single piece, cut-out material (well known food grade or food safe cardboard paper) that is folded about one or more fold lines to form tray 102 of takeout food container 100. It should be noted that the fold lines may be scored lines, perforated lines, or simply indicated by markings.

Further, takeout food container 100 includes two sleeve cover pieces 208 and 210, which are comprise of a second flat, single piece, cut-out material (food grade or food safe cardboard paper) that are folded about one or more fold-lines to form sleeve covers 104 and 106 of takeout food container 100.

Optional dividers 212/288 are also comprised of flat, single piece, cut-out material (food grade or food safe cardboard paper) that are folded about one or more fold-lines to form the dividers 202, which may then be inserted in tray 102 to compartmentalize tray 102.

It should be noted that no adhesives or other additional coupling mechanisms is needed or required in the entire assembly of takeout food container 100. This makes takeout food container 100 food-safe and easy to store, ship, and assemble. As importantly, flat cardboard pieces make it easy to ship a large number of trays, sleeves, and divider pieces in a very small form factor.

It should further be noted that since both first and second sleeve cover pieces are identical, only a single manufactured cut-out (for example, press cut) is required. This means one cut-out configured may be used for both the first and the second cover pieces. Accordingly, only two press cuts may be needed to press-cut the tray piece and sleeve cover pieces.

As indicated above, the divider pieces (compartmentation pieces or inserts) 212 and 288 are optional that when used, would divide or compartmentalize interior space of tray 102.

All divider pieces 212 and 288 are formed from a flat, single piece, cut-out material that are folded about fold lines. Additionally, all divider pieces 212 and 288 also include interlocking protruded (projecting) tabs 204 that when inserted into corresponding slots 148 of tray 102 (or other divider slots 290), allow the dividers 212 and 288 to interlock and remain in place. Further, larger dividers 212 may optionally include slits in a form of slots 290 for insertion of interlocking protruded tab 204 of smaller or other dividers 288 (FIGS. 5A-9, 5A-10., 5B-6, and 5B-7).

There are a large number of ways of dividing or compartmentalizing tray 102. In fact, numerous combinations and permutations of different number, size, and shape of divider pieces may be used to generate a large number of different size tray compartments, with only a non-limiting, non-exhaustive examples shown for discussion purposes. For example, only a single larger divider piece may be used or, alternatively, only a single smaller piece may be used, and so on.

The compartments may optionally hold other well-known containers for example. Alternatively, individual compartments may directly hold different foods (such as cooked rice, fish, etc.).

The method of assembly of the divider pieces large or small is similar. For larger dividers 212 shown in FIGS. 5A-1 to 5A-10:

Lay large divider 212 flat and fold section 292 also labeled as A outward on linear fold line 306;

Fold section 294 also labeled as B inward on linear fold line 308;

Fold section 296 also labeled as C outward on linear fold line 310;

Fold section 298 also labeled as D outward on linear fold line 312;

Fold section 300 also labeled as E inward on linear fold line 314;

Fold section 302 also labeled as G outward on linear fold line 316;

As best shown in FIG. 5A-8, large divider 212 is now completed, which now may be inserted in tray 102 (FIG. 5A-9), with interlocking protruding tabs 204 of larger divider 212 inserted into slots 148 of tray 102 (FIG. 5A-10).
