Description

BACKGROUND

Field of the Disclosed Subject Matter

The present disclosed subject matter relates to a food container for packaging and serving of food items, such as chicken nuggets, french fries, and other bite-size foods. The present disclosed subject matter includes a container for holding food items that can be configured to securely fit into a standard car cup holder.

Description of Related Art

A variety of food items, such as french fries, onion rings, chicken nuggets, popcorn shrimp, and other bite-size foods, are often served from small paperboard containers. These food containers can be pouch-shaped, such as commonly used for french fries, or can be box-shaped and have a lid to contain the food item, such as deli items or the like.

Containers of this type can be formed of foldable paperboard, and can be a single-use product used in large quantities. As such, it can be desirable to reduce or minimize the costs associated with materials, manufacturing, storage, shipping, manner of use, and the like, of such containers.

It can also be desirable to provide a food container with a divider therein to separate the interior of the container into more than one portion or compartment. In this manner, each portion or compartment can contain a serving of a different product, with the different products separated by the divider.

A number of food products are often dipped into sauces or condiments, such as ketchup, mustard, or mayonnaise, before consumption. Many food service establishments provide bulk containers of these condiments and small paper or plastic cups into which the condiment can be dispensed. Alternatively, the condiments may come prepackaged in a sealed container.

If the food product is consumed by a person while seated at a table, the condiment containers can be placed on the table. However, if a person wishes to walk with the container or to eat the food product while driving a vehicle, the use of a condiment becomes more difficult. Both the condiment cup and food container must be held in one hand while the other hand grasps an item of food and dips it in the condiment.

It is also known that certain food items, such as fried chicken, emit moisture or water vapor along with latent heat stored in the food due to cooking and heating. Some of this latent heat and moisture can condense on and be reabsorbed by the food item itself, making the food item soggy, less crispy, and tough to eat. Also, the water vapor can condense on the interior surfaces of the container and drip down towards the bottom of the container for the bottom pieces of the food item to absorb. If air circulation adjacent to and around the food item is poor, the water reabsorption by the food item increases since the latent heat and the resultant water vapor is further prevented from circulating away from the food item. Further, if air from inside the container not allowed to be exchanged with the air from outside the container, condensation of the water vapor on the inside of the container is more likely. Even if a small amount of water vapor escapes from the food item and condenses, or is prevented from circulating away from the food item, this amount can be enough to make the food item undesirable.

It therefore can be desirable to provide a food container with a condiment holder that is integrally formed with a food container and capable of securely retaining a condiment receptacle even when the food container is carried or jarred, along with a secure lid to contain the food item and keep the food item warm yet allow sufficient venting to prevent the food item from becoming soggy or otherwise undesirable. It also can be desirable to provide a food container configured to securely fit into a standard car cup holder.

As embodied herein and shown in FIGS. 14-26, the fourth flap 20 can have a foldable support formed therein. The foldable support can be joined to the fourth flap by a foldable support flap fold line. Additionally, the foldable support can be joined to the first body portion by a foldable support body fold line.

Exemplary embodiments of the disclosed subject matter can include a container or a blank for forming a container having a divider to divide the containers into one or more compartments (for purpose of illustration and not limitation, see containers and corresponding blanks 101-113). Exemplary containers having dividers can also be found in U.S. Provisional Patent Application No. 62/000,704, filed May 20, 2014, which is incorporated by reference herein in its entirety. For purpose of illustration and not limitation, containers 101-113 can be sized to fit into a standard car cup holder. As embodied herein, the containers can include divided, open top, scoop designs (for example and as embodied herein with a flap 30 disposed to form an integral sliding divider).

For purpose of illustration and not limitation, the body portions of the container (e.g. body portions 11, 12, 13, and 14) can have a tapered sidewall, which can increase product holding capacity. For purpose of illustration and not limitation, as embodied herein, the sidewalls can taper at an angle of 12 degrees. However, any suitable degree of taper can be used depending on the desired application, capacity and/or base profile. Additionally, the blanks 101-113 can be adapted to form folding carton containers 101-113, which can include an auto-bottom style glued base 50 (see e.g., FIGS. 7-26) or a double center locking bottom tuck arrangement (see e.g., FIG. 3, see also FIGS. 1-2, 4-6) that can secure the bottom panels (51, 52, 53, 54) together and can provide mounting portions (e.g. when tabs 55 are inserted into perforation 56 proximate to perforations 57 and 58) which can secure the compartment divider panel (e.g. center portion 32 of flap 30) in a desired position. The latter configuration, for example, can be formed without adhering the divider panel (e.g. flap 30) to the carton front body panel (e.g. body portion 13) by means of a glued flap (e.g. engagement portion 33).

For example and not limitation, the tuck flap base closure arrangement can provide improved product compartmental division. As embodied herein, the divider panel (e.g. central portion 32 of flap 30) and the double bottom tuck mounting portions can prevent or inhibit food from travelling from one compartment side to the other. Alternatively, for example and not limitation, the auto-bottom flap base closure arrangement can include inner carton clearance for the initially inwardly-folded auto-bottom flaps. As such, the product divider panel can, for example, be configured to not extend down into the base 50 of the container. For example and not limitation, the divider panel can remain raised by approximately 1 and ⅛ inches, which can allow some smaller products to migrate from one side of the divided carton to the opposite side.

For purpose of illustration and not limitation, the tapered container can include inwardly folding panels 41, 42, 43, 44, embodied herein proximate the corners of the body 10 of the container proximate to the base 50, to allow the container to securely fit into a standard car cup holder. For example and not limitation, as embodied herein, each inwardly folding panel (e.g. inwardly folding panel 41) can be triangular, and can have a first side (e.g. 41a) and a second side (e.g. 41b) separated by a fold line. For purpose of illustration and not limitation, the fold line of each inwardly folding panel 41, 42, 43, 44 can be substantially parallel to and/or coincident with the fold lines between the respective body panels 11, 12, 13, 14 and flap 30. The inwardly folding panels 41, 42, 43, 44 can be activated by seating the container on top of a cavity (for example and without limitation, a standard cup holder cavity in a car) and urging the container downward into the cavity. The inwardly folding panels 41, 42, 43, 44 can fold or deflect inwardly. For purpose of illustration and not limitation, as embodied herein, each panel portion (e.g. 41a, 41b) can taper from the carton base 50 corners outwardly ⅜ inches to a height of 1 and ½ inches with a 3/16 inches release cut on the carton fold score located at the top of each inwardly folding panel (e.g. 41). When folded or urged inwardly; the inwardly folding panels 41, 42, 43, 44 can also provide venting of air and moisture from the interior of the carton.

Any suitable combination of height, top tuck (e.g. lid or flap 20) shape, and optional condiment sauce holder (e.g. foldable supports) can be employed. Alternatives of the tapered container having a divider, a lid, two foldable supports, and four inwardly folding panels are described herein with reference to FIGS. 1-6. For example and not limitation, curved score top sides (which can provide additional carton height) can be combined with curved tapered top tuck flap (e.g. flap 20). Additionally, perforated tear down sides with additional side score can provide integrated (e.g. board usage) foldable supports in flaps 60 and 80, which can be used for example to hold an additional container, such as a sauce cup. Each container and corresponding blank 101-104 can have dual locking bottom tuck flaps to secure inner divider panel into a desired position, as described above.

The container and corresponding blank 105 can have the similar features as described above referring to 101-104, and can include an auto-bottom flap configuration, as described herein. The container and blank 106 can have the similar features as 105, and can include planar score side panels and a straight, downwardly tapering top tuck flap 20. The container and blank 107 can include an auto-bottom design with a uniform width bottom and straight across top tuck flap 20 having two foldable supports die cuts incorporated into extended flaps 60 and 80. A lid (e.g. main portion 21 of flap 20) can be contoured to hold the rims of an additional container, such as a sauce cup, when the cups are disposed therein and the container is in a closed position. Furthermore, the contour of the lid (e.g. main portion 21) can allow for venting through apertures of activated or unactivated die cut foldable supports.

Container and blank 108 can include an auto-bottom design single foldable support positioned in rear of top tuck flap (e.g. flap 20), and can have a straight downward tapering top tuck flap 20. Container and blank 109 can include similar features as 108, and can include curved score sides and curved downward tapering top tuck flap. Container and blank 110 can include similar features as 109, but without the foldable support in the flap 20. Container and blank 111 can include similar features as 109, but with two foldable supports formed in the rear of top straight tuck (e.g. flap 20) and additional score added at back edge of the foldable supports to allow flap 20 to be folded rearward to reduce the space needed, for example in a car cup holder, to hold the container. Container and blank 112 can have a similar curved score side panel/curved top tuck design to 105, and can include two foldable supports formed in the rear of top tuck flap 20. Container and blank 113 can have a similar straight downward tapered tuck design to 106, and can include two foldable supports formed in the rear of top tuck flap 20.

The disclosed subject matter includes divided containers sized to fit into a standard car cup holder and hold different products, including a “protein and starch” meal of portable “finger foods,” such as fries/potato wedges and chicken nuggets, onion rings and “sliders”, fish bites and chips, or the like.

It is to be recognized that the dimensions and relative proportions of the containers and corresponding blanks 101-113 will vary according to the application, desired capacity, and intended use of the food container or blank. While a food container formed by blanks 101-113 having a taper angle of 12 degrees is illustrated in FIGS. 1-26, one of ordinary skill will recognize that any suitable shape and depth of food container and corresponding blanks 101-113 can be employed and the disclosed subject matter is not so limited. Suitable shapes of containers include rectangles, triangles, cylinders, ovals, various polygons, etc., having any suitable dimensions.
