US 20070278122 A1
Abstract
Two food elements are supplied in a container assembly which may be placed on a horizontal support surface or supported in an automobile cup holder. A smaller secondary cup is received within a secondary cup cavity cantilevered to one side of a thermoformed thermoplastic primary container which has exterior dimensions suited to a cup holder. The primary container has a main compartment which receives another food element. The base of the primary container is inclined from the rim of the primary container, such that the center of gravity of the primary container with secondary cup and edible material overlies the primary container bottom wall when the bottom wall is supported on a horizontal surface. A column in the primary container side wall extends from a protruding toe portion of the bottom wall to engage and support the secondary cup cavity.

STATEMENT AS TO RIGHTS TO INVENTIONS MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

Not applicable.

BACKGROUND OF THE INVENTION

The present invention relates to portable containers in general, and to containers for multiple food elements in particular.

Drivers of automobiles at times find it convenient to consume food or beverage while operating a vehicle. Time pressures, length of commute, remoteness of location, or other factors make it desirable to take refreshment in the automobile while driving. Nevertheless, the demands of attentive driving call for the vehicle operator to keep at least one hand on the steering wheel, and to be ready to bring both hands to bear on short notice. Modem automobiles cater to this need by providing convenient receptacles for standard sized beverage containers. These cup holders are positioned within arm's length of the driver, and will readily accept beverage cans, drink bottles, and cups. Cup holders are available in a variety of configurations and styles, including ones that collapse within a dashboard, such as those shown in U.S. Pat. No. 6,866,318, the disclosure of which is incorporated by reference herein.

In recent times packaged food manufacturers have expanded offerings of non-liquid food products to drivers by providing these products in containers conveniently sized for a vehicle cup-holder, and having a dispensing mechanism suited to being operated with a single hand. Snack chips and similar products, for example, have been packed in stiff bottles with a wide mouth.

Some food products, however, are comprised of multiple components which are best combined immediately before consumption, i.e. components of different temperature, or crisp components and liquid sauces or condiments. Although concentric containers have been developed for such purposes as keeping milk and cereal separate until introduced into the consumer's mouth, there remains a need for a package adapted to the on-the-go consumption of food products with multiple components which need to be kept side-by-side until the time of eating. Moreover, such a container should be amenable to both use on a table-like surface and for support within a vehicle cupholder.

SUMMARY OF THE INVENTION

A container assembly of this invention presents two food elements in an arrangement which may be placed on a horizontal support surface or supported in an automobile cup holder. A smaller secondary cup, filled for example with a condiment, is received within a secondary cup cavity formed in a thermoformed thermoplastic primary container which has exterior dimensions suited to a cup holder. The primary container has a bottom wall with an upwardly extending side wall which defines a main compartment which receives another food element, for example bread sticks. The side wall extends upwardly from the bottom wall and is terminated at an upper rim which to extends in a first plane. The secondary cup cavity is molded into the primary container side wall so as to project sidewardly from the main compartment in a cantilevered fashion. The secondary cup cavity has a lower wall which extends outwardly from the primary container side wall, and a side wall which extends upwardly from the secondary cup cavity lower wall, and which adjoins the primary container side wall. The secondary cup is positioned within the secondary cup cavity and supported on the secondary cup cavity lower wall within the secondary cup cavity side wall. The primary container bottom wall has portions which extend in a second plane which is below the first plane and is tilted from the first plane such that the center of gravity of the primary container with secondary cup and edible material overlies the primary container bottom wall when the bottom wall is supported on a horizontal surface. Portions of the main compartment side wall define a column which extends upwardly from a protruding bottom wall toe to the secondary cup cavity lower wall. The column is inclined with respect to the bottom wall away from a plane which is perpendicular to the bottom wall.

It is an object of the present invention to provide a container for two consumable elements which keeps the elements separate until time of consumption.

It is another object of the present invention to provide a container for two edible components which can be supported in an automotive cup holder.

It is an additional object of the present invention to provide a container which supports one food element in a main compartment, and another in a cantilevered position, yet which remains stable when supported on a horizontal surface.

Further objects, features and advantages of the invention will be apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring more particularly to FIGS. 1-6, wherein like numbers refer to similar parts, a container assembly 20 is shown in FIG. 1. The container assembly 20 is suited to the packaging for sale of two component foods comprised of a first food element 22, for example baked bread sticks, and a second food element 24, for example a liquid condiment or dip, as shown in FIG. 4. The container assembly 20 is comprised of a primary container 26 which receives a smaller secondary cup 28, and may be covered by a lid 30.

Both the primary container 26 and the lid 30 may be formed of plastic in a conventional molding process, for example from sheet material in a conventional thermoforming process, for example, from polypropylene, or alternatively by injection molding. As best shown in FIG. 4, the primary container 26 has a bottom wall 32 with portions extending in a first plane which corresponds to a horizontal supporting surface 34, such as a table or counter. As shown in FIG. 3, the bottom wall 32 is generally circular with a protruding toe 36 which underlies a secondary cup cavity 38. The primary container 26 has a side wall 40 which extends upwardly from the bottom wall 32 and which terminates at a rolled rim 42. The rim 42 extends in a plane which is tilted from the plane of the bottom wall 32, as best shown in FIG. 4. The tilt may be about 8 degrees, but may be as much as 15 degrees, depending upon the particular desired configuration of the primary container.

The bottom wall 32 and the side wall 40 define a main compartment 44, generally frustoconical in shape, which is adapted to contain the first food element 22. The side wall 40 is dimensioned to be received in a conventional automobile cup holder. The side wall 40 extends downwardly from the rim 42 about an axis of revolution which is perpendicular to the plane of the rim 42. In other words, the side wall has a constant draft with respect to the plane of the rim, for example about 5 degrees. As a result, the container assembly 20 may be received within the cup holder so the rim will remain generally parallel to the cup holder. Although cup holders have been designed to hold a variety of sizes of container, they are generally shaped to adequately hold a conventional 12 oz. aluminum beverage can which typically has a diameter of about 2 11/16 inches.

As shown in FIGS. 2 and 3, portions of the primary container side wall 40 protrude outwardly towards the secondary cup cavity 38 to define a column 46 which extends between the bottom wall toe 36 and the lower wall 48 of the secondary cup cavity. The column 46 is defined by two radiused transition walls 50 on either side of a front wall portion 51. The column 46 is inclined with respect to the bottom wall 32 towards the center of the main compartment, or, put another way, the column is inclined away from a plane which is perpendicular to the bottom wall. The primary container side wall 40 defines a substantially frustoconical surface having a center axis. When the bottom wall 32 is supported on a horizontal surface, portions of the bottom wall toe 36 extend away from the center axis to underlie the secondary cup cavity lower wall 48.

The secondary cup cavity 38 is configured to receive the secondary cup 28, which may be a conventionally sized dip or condiment container. Generally the secondary cup 28 will be an axisymmetric generally frustoconical plastic molding with a side wall 52 which extends upwardly from a bottom wall 53 and terminates in an upper rim 54. As shown in FIG. 3, the lower wall 48 of the secondary cup cavity 38 is generally circular, but has a three-sided relief 56 where it joins the column 46. The secondary cup 28 and its contents are supported on the lower wall 48. The lower wall 48 of the secondary cup cavity 38 is preferably formed parallel to the rim 42 of the primary container 26. It will thus be inclined with respect to the bottom wall 32 of the primary container 26.

The secondary cup cavity 38 has a side wall 58 which extends from the primary container side wall 40 and which extends upwardly from the secondary cup cavity lower wall 48. The secondary cup cavity side wall 58 is generally frustoconical and of a similar diameter to the side wall 52 of the secondary cup 28, such that the secondary cup is received securely within the secondary cup cavity. To prevent the escape of the secondary cup 28 from the secondary cup cavity into the adjoining main compartment 44 with which it communicates, the secondary cup cavity side wall 58 wraps more than 180 degrees around the secondary cup, preferably at least 210 degrees, and in the illustrated example, about 240 degrees. The secondary cup 28 is thus restricted from entering the main compartment 44 by two projecting corners 60 where the primary container 26 side wall 40 adjoins the secondary cup cavity 38 side wall 52 above the secondary cup cavity lower wall 48.

As the secondary cup cavity 38 is cantilevered off to one side of the primary container 26, the main compartment 44 is unobstructed, and offers ample capacity for receiving the first food element 22. Moreover, because the secondary cup cavity 38 only extends sidewardly from the primary container 26 at an upper region of the container, adjacent the rim 42, it does not unduly extend the effective diameter of that portion of the container (that is the lower portion), which is received within the cup holder. For example, about the lower two inches of the primary container may be received within the cup holder. However, it will be readily observed that this unsymmetric cantilevered secondary cup cavity, when loaded with the secondary cup and its contents, will tend to cause the center of gravity of the entire assembly to move away from the vertical axis of the primary container.

As shown in FIG. 5, in broken line outline 62, if the bottom wall of the primary container were formed in a plane which was parallel to the rim, so that the axis of the primary container extended simply vertically, the center of gravity 64 of the primary container and the loaded secondary cup would be outside the bottom wall of the primary container. The weight of the first food element loaded in the primary container main compartment may be adequate to counterbalance the off-center secondary cup, but when some or all of the first food clement is removed, the primary container and secondary cup may no longer be supported on the bottom wall, and the cup would tip over. However, because the bottom wall of the primary container is tilted with respect to the axis of the primary container, the toe of the bottom wall extends beneath the center of gravity of the loaded secondary cup and the primary container, giving the entire assembly 20 a desirable stability when supported on a horizontal support surface.

The lid 30 has two levels to accommodate tall product within the main compartment, while restricting the vertical escape of the secondary cup from the secondary cup cavity. The lid 30 has a dome 66 with a top wall, and a downwardly extending side wall 67. A lower level wall 68 extends outwardly from the lid dome side wall 67 to encircle the dome as a narrow flange and to overlie the secondary cup cavity. A skirt 70 extends downwardly from the lower level wall 68, and a lower flange 72 extends outwardly from the skirt 70. A plurality of detents 74, shown in FIG. 1, extend inwardly from the lid skirt 70, and engage beneath the primary container rim 42 to removably secure the lid to the primary container.

To aid in ejecting the primary container from its thermoforming mold, the primary container 26 is preferably formed with an ejection platform 76 which is parallel to the plane of the primary container nm.

As shown in FIG. 6, the primary container 26 may be film sealed for preserving the freshness of the contents, for providing tamper evidence, or for use without a lid. The film seal 78 is applied in a conventional fashion to a flat region 80 which extends in a plane at the top of the primary container. The secondary cup 28 with its contents 24 may also be sealed with a film 92. The primary container 26 is shown supported in an automobile cup holder 86 in FIG. 6. Although the domed lid shown in FIG. 4 allows the primary container to hold a food element which is taller than the side wall, when used with food elements 122 which do not protrude above the level of the rim, a simple flat lid 84 may be employed.

For most food elements 22, 24, it is desirable to allow the potential customer to see within the container assembly 20 before purchase. Therefore the primary container and lid are preferably formed from transparent plastic. However, when a warm moist food element, such as a warmed bakery product is placed within the container, there is a possibility for vapor condensation on the primary container or lid. This fogging can obstruct the potential customer's view of the container assembly's contents. One way to avoid fogging is to enclose the food element in a cellophane bag which retains any vapor. Another approach is to form a rib along the lid which allows a free exchange of the container's interior air with the outside environment. Such a rib may be formed, for example, in the lower level wall 68 of the lid, the rib extending from the skirt 70 across the lower level wall 68. Alternatively, the lid 30 may be formed so as not to form a tight seal with the primary container 26, such as by making the perimeters of the primary container rim 42 and the lid skirt 70 different, thereby allowing ventilation of the main compartment 44 between the lid and the primary container. In another alternative approach, conventional antifog additives or coatings may be used with the lid and primary container.

In addition to being used with bread sticks and dip, as illustrated, the container assembly may be used with a wide variety of food elements, for example with vegetables or fruit and a dip; ice cream and a topping; etc. Thus it will be seen that the products to be contained are varied, and, based on product need, the material from which the primary container is formed could be adjusted to be suitable for temperatures ranging from freezer applications to oven temperatures, from direct fill to retail display with a limited shelf life. Besides polypropylene, then, the primary container and lid may be formed of polyethylene terephthalate (PET); high-heat styrenic copolymers such as Nova Chemicals DYLARKŪ resins; Styrene Maleic Anhydride (SMA) resin, or other appropriate moldable plastic materials.

It is understood that the invention is not limited to the particular construction and arrangement of parts herein illustrated and described, but embraces all such modified forms thereof as come within the scope of the following claims.
