The invention relates to a package for containing a dry food product, such as instant coffee, powdered cocoa, dehydrated soup, etc., wherein the package includes a cup in which the food product is served after mixing the food product with water.
BACKGROUND OF THE INVENTIONSome convenience food products and hot beverages, such as coffee, hot cocoa, or soup, are often prepared from dry starting ingredients by adding hot water. For instance, one existing commercial product comprises dry soup mix contained in an expanded polystyrene (EPS) cup and sealed closed by a membrane. To prepare and serve the soup, the membrane is removed and hot water is added to the cup. The soup can be eaten out of the EPS cup. Expanded polystyrene offers the advantage of being a good thermal insulator, so that the cup can be held comfortably in the hand as the soup is consumed.
Instant coffee and hot cocoa also are often prepared and served in expanded polystyrene cups, although typically the dry instant coffee or powdered cocoa mix are not packaged in the cup, but rather are packaged separately in jars or single-serving packets.
While EPS is a good thermal insulator, it has other drawbacks. For instance, EPS by itself is a relatively poor oxygen and water vapor barrier. Thus, for packaging food products that must be protected from oxygen and/or water vapor infiltration, it is generally necessary to use barrier EPS, which comprises a layer of EPS laminated to a barrier film. Widespread recycling of consumer food packages made of barrier EPS has not yet taken hold, which means such packages wind up in landfills.
SUMMARY OF THE INVENTIONThe present invention addresses the above needs and achieves other advantages, by providing a package for a food product such as instant coffee, powdered cocoa, dry soup mix, or the like, that is prepared and served in the package, wherein the package can be formed of materials that are widely recycled. In preferred embodiments the package can be thermoformed from polypropylene or the like.
In one embodiment of the invention, the package comprises a primary container formed as a tapered plastic cup, and a cup holder also formed as a tapered plastic cup. The cup holder nests inside the primary container when the food product is initially placed in the package and the package is sealed. The food product can be contained in the bottom of the primary container, or alternatively in the bottom of the cup holder. A membrane is sealed across the top of the cup holder when it contains the food product. A shrink film can envelope an upper portion, or all, of the package to hold the primary container and cup holder together and also prevent infiltration of debris, water vapor, and gases. The package is convertible into a serving configuration by removing the shrink film and removing the cup holder from the primary container. If the food product is contained in the cup holder, the membrane is peeled off and the food product is poured from the cup holder into the primary container. Then the primary container is nested inside the cup holder, and hot or cold water is added and mixed with the food product. The cup holder provides thermal insulation so as to protect the consumer's hand from directly contacting the primary container when the package is held in the hand. Thus, hot beverages or food can be consumed from the package while the package is held comfortably in the hand.
The primary container includes a radially outwardly projecting rim at the top. The cup holder has a radially outwardly projecting flange at its top end, and a skirt depends from the flange to form an annular channel between the skirt and the side wall of the cup holder. In the packaged configuration of the package, when the cup holder is nested into the primary container, the rim of the primary container is received up into the channel of the cup holder. A snap fit between the cup holder and primary container can be provided, if desired. The skirt preferably is flared outwardly toward its lower end, and includes an outwardly projecting flange at its lower end, to form a relatively wide structure that is easily gripped. The skirt and flange also help provide stability to the package when inserted into an automobile cup holder.
The shrink film that is wrapped about the package in the packaged configuration can provide tamper evidence. In one embodiment, the film extends at least part of the way down the primary container and includes a line of weakness (perforations or the like) permitting an upper part of the film to be detached from a lower part so that the upper part can be removed to convert the package into the serving configuration. The lower part of the film remains on the primary container. The film can be printed with visual elements such as indicia or graphics.
In a preferred embodiment of the invention, the cup holder and primary container have cooperating locking features that engage each other when the package is in the serving configuration to lock the primary container into the cup holder. The locking features can comprise one or more projections and recesses. For example, in a preferred embodiment the inner surface of the cup holder defines a circumferential groove and the outer surface of the primary container defines a circumferential ridge or raised region that engages the groove of the cup holder. There can be more than one groove and ridge axially spaced apart. The groove(s) and/or ridge(s) can extend completely or partially about the circumference.
