The cap includes a plurality of protrusions pointed toward the bowl which guide the second food product component for uniform dispersion.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention pertains to the packaging of food products, and more particularly to food product packaging which aids in dispersing, on demand, a solid food component, such as a cheese sauce, onto a second food component such as vegetable chips, crisps, or the like.




2. Description of the Related Art




A wide variety of dips and sauces has been provided to complement food products such as tortilla chips, potato chips and crisps, for example. The complementary sauces and dips may be served at a variety of temperatures ranging from refrigerated temperatures to much hotter, elevated temperatures. Typically, when served at elevated temperatures, the sauce or dip is removed from a container and placed in a cooking vessel or dish for heating. Advances in packaging and serving are continually being sought.




A problem associated with multi-component food products of the type described above, in addition to the extra steps and use of dishes associated with separate heating, is the uneven dispersion of one food component over the other. For example, while a cheese sauce may be served in a cup, for use as a dip, it is becoming increasingly popular to pour a melted cheese sauce over a pile of food chips. Care must be taken to drizzle or otherwise pour the cheese sauce evenly across the mound of chips. Too often cheese sauce is concentrated in a localized position of the mounded pile of food chips. Improvements in dispersion and a reduction in the amount of attention paid to dispersion techniques is being sought.




SUMMARY OF THE INVENTION




It is an object of the invention to provide a multi-component food product in which a first solid food component is converted into liquid form for use with a second food component such as food chips or the like.




Another object of the present invention is to provide a packaging for food products of the above type which are suitable for use in microwave ovens.




Yet another object of the present invention is to provide automatic or unattended even dispersion of the liquified food product onto a second food component.




A further object of the present invention is to provide packaging of the type described above suitable for use in mass production assembly operations.




Yet another object of the present invention is to provide food packaging of the above-described type which is suitable for use with high volume gas flushing operations carried out immediately prior to sealing of the package, so as to preserve the freshness of the food components.




These and other objects of the present invention are provided in a combination of a food product and package, assembled for transport to a remote location, which comprises a bowl that has a side wall and a bottom wall which cooperate to define an interior cavity, and an upper end. A cap or lid dimensioned to close the upper end of the bowl has a central cup-like depression that receives the second food component in a solid cake form. The central portion of the lid includes a plurality of protrusions which extend into the second food product component. The cap includes a pair of diametrically opposed fluted portions disposed on either side of the central portion. The bowl defines a pair of diametrically opposed fluted portions complementarity shaped with the fluted portions of the cap so that the cap and bowl nest interfitting with the cap in both shipping and heating inverted positions. The cap in the heating position presents protrusions downwardly which extend toward the bowl interior with the outer surfaces of the protrusions guiding the second food product component for uniform distribution about the interior of the bowl.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Turning now to the drawings, a package for a food product is generally indicated at


10


. Package


10


includes a cap


12


and a cup or bowl


14


. Cap


12


is moveable between a storage position illustrated in

FIG. 1 and a

cooking or heating position illustrated in FIG.


2


. Cap


12


and bowl


14


are preferably made of plastic materials suitable for heating in a microwave oven and, like bowl


14


, cap


12


is preferably made of a single integral molded construction.




Referring to

FIG. 4

, bowl


14


includes a side wall


16


and a bottom wall


18


having a central raised portion


20


forming an outer annular recessed portion


22


.

FIG. 4

shows bowl


14


filled with a first food product component


24


in the form of a relatively rigid tortilla chips


24


. The food product component


24


could also comprise any of a number of farinaceous foods which include, for example, grain and cereal products, such as soft and hard breads and crackers as well as vegetable products such as vegetable chips, including chips made of potato or corn.




Food product component


24


preferably has a thin, rigid or semi-rigid form, but may also be soft and pliable. The outer annular recess


22


provides a convenient collection point for a second food product component


28


carried in cap


12


in the manner shown in FIG.


4


. As will be explained herein, cap


12


is inverted by a consumer to the position shown in FIGS.


2


and


6


-


8


and subjected to elevated temperatures which cause the second food product component


28


to disperse onto the first food product component


24


. Any excess second food product component


28


not retained by the first product


24


is collected in the portions of the outer annular recesses


22


to allow a consumer to scrape second food product component from the bottom of bowl


14


.




Turning now to

FIGS. 4 and 5

, bowl


14


includes a recessed rim


32


having an outwardly extending flange


34


with an upper surface


36


(see

FIG. 1

) for conveniently receiving a sealing film


38


made for example of plastic or aluminum foil. Sealing film


38


cooperates with bowl


14


to completely enclose food products


24


,


28


as well as the entire portion of cap


12


and the interior of bowl


14


. If desired, sealing film


38


could be replaced with other packaging components known in the art to cooperate with bowl


14


to seal the contents thereof.




As shown in FIGS.


1


and


3


-


5


, package


10


is configured for shipment, whereas FIGS.


2


and


6


-


8


show package


10


configured for heating which releases the second food component


28


for contact with the first food component


24


, as illustrated in

FIGS. 7 and 8

. Cap


12


has a first side illustrated in

FIG. 1

with a central recess portion


40


. A plurality of separate spaced apart protrusions


42


extend above an end wall


44


as can be seen for example in FIG.


4


. End wall


44


is joined to a frustoconical side wall


46


so as to receive support from a truncated circular outer wall portion


48


.




The truncations in wall portion


48


form segment shaped openings


49


(see FIGS.


1


and


2


). In this manner, cost effective conventional mass production gas-flushing techniques can be applied to package


10


immediately prior to the application of sealing film


38


. The gas-flushing may be employed, for example, to preserve the freshness, crispness, flavor and other desirable perishable qualities of the food components


24


.




In the storage position illustrated in

FIG. 4

, the outer wall portion is nested within recess


32


and is generally coextensive with the outer marginal portion


34


of bowl


14


. The nested arrangement provides a stable well-sealed arrangement for the readily application of sealing film


38


. The application of sealing film


38


, as with the filling of food product components


24


,


28


and the assembly of cap and bowl portions, is well suited for high speed mass production techniques.




Referring to

FIGS. 1 and 2

, cap


12


includes a pair of diametrically opposed fluted portions


52


having first narrower parts


52




a


and second, wider parts


52




b


. Bowl


14


has diametrically opposed fluted portions


56


generally coextensive with the fluted portions


52


of cap


12


. The fluted portions


56


of bowl


14


include first narrower parts


56




a


and second wider parts


56




b


. As shown in

FIG. 3

fluted portions


52


,


56


of cap


12


and bowl


14


nest within one another with the narrow parts


52




a


,


56




a


adjacent one another and the wider parts


52




b


,


56




b


adjacent one another.




Referring to

FIG. 2

, with cap


12


in the inverted, heating position, the openings


49


and the cooperating fluted portions of cap


12


and bowl


14


provide passageways for the escape of steam through exit openings


62


. As can be seen in

FIG. 2

, end wall


44


and trapezoidal side wall


46


form a cup portion which, when inverted in the manner shown in

FIG. 4

, for example, can conveniently receive a liquified second food component


28


. Preferably, the second food component


28


is allowed to harden to form a cake contained within end wall


44


and side wall


46


, being interrupted by protrusions


42


. Preferably, as indicated in

FIG. 4

, second food component


28


is filled slightly above the free ends of projections


42


.




In the preferred embodiment shown in

FIGS. 1 and 2

, for example, projections


42


include a central protrusion


42


surrounded by a plurality of equally spaced protrusions arranged in a circular pattern. Other arrangements of protrusions, and arrangements including differing number of protrusions are also contemplated by the present invention. As illustrated in the enlarged cross-sectional view of

FIG. 9

, projections


42


are preferably continuously rounded and include a rounded free end. In a preferred embodiment, the rounded free end of projection


42


is generally hemispherical in shape, although other shapes could be employed, as well.




In use, a consumer removes the film seal


38


or other conventional seal for bowl


14


, exposing the cake of second food component


28


. If desired, the cake of second food product component


28


could be separately sealed with a peel seal of appropriate material such as plastic film or aluminum foil and an outer flat band


64


(see

FIGS. 1 and 2

) is made available for this purpose. As will be appreciated by those skilled in the art, the application of seal


38


to the upper end of package


10


, in the manner indicated can be readily accomplished using conventional equipment and mass production assembly techniques.




Upon removing the seal


38


, the user accesses cap


12


, inverting the cap to the position indicated in FIGS.


2


and


6


-


8


with the cake of second food product


28


facing in a downward direction, into the interior of bowl


14


. The cake is then subjected to conditions which cause the second food product to take on a liquified form. Preferably, the cake


28


is heated, causing it's outer surface to become liquified and drip onto the first food product component


24


in the manner indicated in

FIGS. 7 and 8

. The protrusions


42


guide the liquified second food product component in a desired dispersion pattern, insuring a uniform coating of the first food product component


24


about the second food product component


28


.




The protrusions


42


, in cooperation with other features of the illustrated embodiment, have been found to satisfactorily distribute the second food product component in a uniform manner across the interior of bowl


14


, and have further been found to release the substantial entirety of the second food product component in the desired manner. As an important feature, a single release of the entire second food product component into the interior of bowl


14


is prevented.




It is believed that retention of the cake of the second food product component during heating is facilitated by surface tension of the product with the protrusions formed by the hollow interior of protrusions


42


, visible for example in FIG.


2


. It is generally preferred, for this reason, and for reasons of economical plastic molding that the protrusions


42


be made hollow in the manner illustrated. Referring to

FIG. 9

, for example, the hollow cavities


70


of protrusions


42


could be conveniently filled with a cooling medium such as ice water or could be made solid, to provide a thermal heat sink mass, although such has been found to be unnecessary. In addition to the thermal functioning of cap


12


during heating, the number and relatively close spacing of protrusions


42


, as well as their relative proportions shown for example in

FIG. 9

are believed to contribute to the controlled release of second food product


28


.




In the preferred embodiment, as mentioned, first food product component


24


comprises vegetable chips, and most preferably tortilla chips. Also, in the preferred embodiment second food product component


28


comprises a cheese sauce having the following characteristic properties.




It is generally preferred that the second food product component be semi-viscous during manufacturing so as to be compatible with mass production filling and assembling techniques. As mentioned, it is generally preferred that the package configuration shown in

FIG. 1

be assembled in high speed production environment, allowing assembly and filling of both food product components immediately prior to application of sealing film


38


. Alternatively, further advantages of the present invention can be realized with the separate assembly of cap


12


and second food product component


28


. For example, the second food product component can be filled in a liquified or semi-viscous state caused for example by heating the second food product component. Caps can be filled in a high speed production environment and introduced into a refrigerated or cooling environment to promote rapid solidification of the second food product component, rendering the assembly less sensitive to non-refrigerated mass production assembly techniques employed to produce package


10


.




In the preferred embodiment, the second food product component


28


forms a cake approximately 3″ in diameter and approximately 0.6″ in height. The protrusions


42


have a maximum diameter of approximately 0.44″ and a height or axial length slightly less than the 0.6″ thickness of cake


28


. The opposed fluted portions of cap


12


each have a width of approximately 2.5″, with band


64


having a diameter of approximately 3.25″ and frustoconical wall


46


having a maximum diameter of approximately 2.9″.




As mentioned, aspects of the preferred embodiment provides packaging for the combination of a cheese sauce and a tortilla chip component, although other combinations of secondary and primary food components can receive the benefits of food package


10


and the assembly and filling techniques employed therewith. For purposes of suggestion, but not limitation, the secondary/primary food component compositions can comprise: cheese sauce over nacho chips, cheese sauce over pretzels, chocolate sauce over one or more brownie cookies, cinnamon frosting over one or more rolls or other bread products, salsa sauce over nacho chips and cheese sauce over popcorn.




Turning now to

FIGS. 10 and 11

, an alternative embodiment of a food package is indicated at


100


.

FIG. 10

shows food package


100


being readied for shipment to a consumer. A plastic overwrap


102


is applied to the upper end of the food package and is sealed to the flange


104


of cup or bowl


106


. The cap


110


of food package


100


has a generally continuous circular outer periphery and covers substantially the entire circular opening defined by flange


104


. Food package


100


is substantially identical to the food package


10


, described above, except that cap


110


provides a continuous cover for the upper end for bowl


106


.
