The inventions relate to an apparatus for delivering a hidden gift to a recipient inside a cake or other food item.
Marking a special occasion, such as a birthday, wedding or holiday, with food and gift giving are age old traditions. In some cultures, special occasion foods and gifts have been enhanced by hiding small trinkets, candies, or more unique gift items inside a prepared food, such as cake, prior to serving so that the gift is a surprise to the recipient. One prior method has been to mix gift items into cake batter prior to baking, but the gift is then exposed to high heat and moisture during baking. Thus, another method is to remove the cake from its pan after baking, and then turn the cake upside down to manually insert the gift item into the cake from the bottom. However, the cake is at risk of being damaged, so that the cake has a less appealing appearance when displayed for the special occasion. Another disadvantage of both of the aforementioned methods is that the gift could be damaged by a knife or other like instrument when cutting or serving portions of the food.
One example of such a special occasion food item is the King Cake, which is popular in New Orleans, France, Belgium and other parts of the world between January 6th (Twelfth Night or the Epiphany) and Mardi Gras, the last day before Lent. A King Cake is a baked confection or pastry having a trinket baked inside of it, and the finder of the trinket is anointed “king” for the forthcoming year. Historically, trinkets have routinely been non-food items such as a plastic or ceramic or porcelain trinkets, sometimes in the shape of a doll. But the difficulty with hiding an inedible surprise into a cake is that the finder could choke on the item, or could damage a tooth. So to avoid that danger, bakeries in the United States have been selling King Cakes without any trinkets, or by providing the trinket separately, outside and alongside of the cake.
In the United States, the Federal Food, Drug, and Cosmetics Act prohibits the manufacture or introduction or delivery into interstate commerce of an adulterated food. 21 U.S.C. § 331. A food is deemed to be adulterated if it is a confectionery and has partially or completely imbedded within it a non-nutritive object, unless the US Food and Drug Administration (FDA) has issued a regulation recognizing that the non-nutritive object is of practical functional value to the confectionery product and would not render the product injurious or hazardous to health. 21 U.S.C. § 342(d)(1). Import Alert 34-02 was issued by the FDA when it became “aware of a product called “Kinder Surprise Eggs”, and similar articles containing imbedded, non-nutritive objects, being offered for sale in the United States. The imbedded non-nutritive objects in these confectionary products were considered to pose a public health risk as the consumer may unknowingly choke on the object.” Import Alert 34-02. Based on the Import Alert, FDA field personnel are instructed to detain import of any such adulterated foods without physical examination. Id.
Accordingly, the inventions feature a method and apparatuses for hiding a surprise non-edible gift item in a cake or other confectionery, so that the gift will be a surprise to the recipient, while at the same time making it impossible for anyone to choke, bite down on, or otherwise ingest the gift. The food item can be sold to consumers as a non-adulterated food, in compliance with the food safety regulations of the U.S. Food and Drug Administration.

The above summary was intended to summarize certain embodiments of the present disclosure. Embodiments will be set forth in more detail in the figures and description of embodiments below. It will be apparent, however, that the description of embodiments is not intended to limit the present inventions, the scope of which should be properly determined by the appended claims.
Embodiments of the disclosure will be better understood by a reading of the Description of Embodiments along with a review of the drawings, in which:
In the following description, like reference characters designate like or corresponding parts throughout the several views. Also in the following description, it is to be understood that such terms as “forward,” “rearward,” “left,” “right,” “upwardly,” “downwardly,” and the like are words of convenience and are not to be construed as limiting terms. The present disclosure features a method of hiding a surprise item in a cake or other confectionery, so that the gift will be a surprise to the recipient, while at the same time making it impossible for one to choke, bite down on, or otherwise ingest the gift unawares. This is achieved by enclosing the surprise item within a container, a.k.a. gift pod, which is inserted into the center of the food, and concealed by a cover or decorations or both until such time as the recipient, server, eater, or other user, reveals the presence of the pod by releasing the pod at least partially, or even completely, from the food item. The gift pod container can have opaque walls to further conceal the identity of the item inside. Alternatively, one or more, or all, of the outer surfaces of the gift pod container are translucent or transparent. The gift pod can have its own bottom wall so as to be enclosed on the bottom of the container, or can be assembled while packaging the item into the gift pod container. The apparatuses and mechanisms herein apply to containers formed either prior to or during assembly of the gift pod container in the device.
The food item can be sold to consumers as a non-adulterated food, in compliance with food safety regulations of the U.S. Food and Drug Administration. The invention also features an apparatus which includes a plate for mounting the food item and having an interior hole extending there through, a hollow tube extending upwardly from the interior hole, the tube defining an opening through the food item and having a first open end at the interior hole and a second open end upward from the plate; a container for holding a concealed item and sized to fit within the tube; a base for holding the plate; and a release mechanism for raising the container through the second open end of the tube, the release mechanism extending from the base to the container through the first open end.
Reference will now be made in detail to the present exemplary embodiments, examples of which are illustrated in the accompanying drawings. Wherever possible, the same or similar reference numbers will be used throughout the drawings to refer to the same or like parts.
The assembly may have a container 130 for holding a concealed item and sized to fit within the tube 714, a base 740, and a release mechanism 910 for raising the container 130 up and out of the food item as shown and described in any of the examples and embodiments herein. The base 740 may be cylindrical as shown in
The plate foundation 700 may be supported by base 740, including any of the base elements, securement features, and examples shown and described herein. The base 740 generally supports an elongated central tube 714 extending from the base 740. A repositionable platform 710 is semi-affixed to the central tube 714 at any height to correspond with any dimensions, including but not limited to height, of the items shown and described herein. As illustrated in
As shown in
a introduce one embodiment of a spring release mechanism 910 to deliver any container as shown and described herein. As illustrated, the release mechanism 910 may be a music box design style mechanism for releasing the container. Applicant has unexpectantly discovered traditional spring pressure from a music box mechanism exerts damaging, excessive force, causing unreliable releasing and/or injury to internal elements and/or frame support 124. Therefore, Applicant has introduced a release mechanism assembly that includes a retractable spring plunger 121 secured about the rotating shaft box mechanism 122 to withstand said pressures and challenges. The retractable spring plunger 121 nose may have a chamfered edge, so that when the container 130 is retracted the platform will retract the nose of the retractable spring plunger 121 after contact with the chamfered edge. Additionally, a linkage may connect the retractable spring plunger 121 about the rotating shaft box mechanism 122, for instance a split key ring 123 shown in
A further embodiment includes any of the plate foundation 700 elements herein in combination with a board member that supports a plurality, including two or more, food items. For instance, the board member may include a securement fastener to fasten at least one food item to provide any of the delivery and presentation operations shown and described herein. The securement fastener may include an adhesive, a hook, a J-hook, a magnet, a linkage, combination thereof, and the like. Those skilled in the art having the benefit of this disclosure will recognize additional securement fastener examples and arrangements.
Generally, the side walls of the gift pod container 130 are derived form a tube shape and the bottom of the container is formed from the upper surface of supper spring seat 152. The top of the gift pod may be derived from cover 120. In operation, a user may place the gift into the container, and push the container 130 into the assembly.
In certain embodiments, the container 130 may have an inner compartment for holding the concealed item. For instance, the concealed item may rest on the top surface of the upper spring seat, which has a ridge around its outer perimeter to receive the walls of the container 130. In certain other embodiments, the compartment may have a floor on which the concealed item rests. Further, an actuator may have elements for holding a spring in its compressed state and for releasing the spring and thereby releasing the container 130 from the tube. The actuator may have an outer element extending through a surface of the base to receive operative actions by a user. Actuator may also have a securing element that is extendable into and across the upper spring seat, for instance through a first hole, which is disposed in the wall of the bottom spring seat, and a second hole, which is disposed in the wall of the upper spring seat. In certain examples, the holes form a passageway across the upper spring seat to hold the spring in a compressed state. Also, the wall of the bottom spring seat may have an internal ridge around its inner perimeter to receive the walls of the upper spring seat.
As shown in
In certain embodiments, the upper spring seat has a third hole and the bottom spring seat has a fourth hole, both of which match up with holes to further define a passageway across the upper spring seat. These elements may be pivotally attached to either end of a connector, which itself is pivotally attached to base through connector pin. In certain embodiments, the outer element is a rod extending through a base hole in the surface of the base to receive hold and release operative actions by a user. The securing element may also be a rod that is extendable into and across the passageway. In operation of these alternative embodiments, a user may push the container/upper spring seat assembly into the internal ridge to house the spring in bottom spring seat. While applying downward pressure on the container/upper spring seat assembly (so as to avoid spring decompression), the user may align the holes to form the passageway, and then pull the actuator outer element through actuator hole a selected distance from the base. In addition, certain embodiments may provide hole alignment guides on the seats to facilitate alignment. A pulling action on the actuator outer element may cause the connector to pivotally push the actuator securing element through the holes, thus holding the container/upper spring seat assembly securely into the base and holding the spring compressed in the bottom spring seat.
In certain embodiments, the food item may be prepared on the base in which the container/upper spring seat assembly is secured. In other embodiments, the food item may be prepared separately and mounted on, or even secured to, the base. Further, the food item optionally includes multiple layers of food item, e.g., of a tiered cake, each such layer having a central food interior hole to, when aligned, accommodate the tube when assembled onto the plate. The tube cover may be applied over the tube to releasably cover the second open end of the tube and to hide the concealed item, and to support any icing or decorative ornament used to decorate food item. In certain embodiments, the tube cover may still be visible after the cake is iced and decorated. In other embodiments, the tube cover may be iced and decorated to cover the tube cover so that the existence of the concealed item remains a surprise.
In certain embodiments, the food item/plate assembly may be temporarily secured to the container/base assembly using any suitable conventional means to prevent accidental slippage. In other embodiments, the food item/plate assembly simply rests on the container/base assembly. In alternative embodiments, the bottom of gift pod container is an integral molded part of the container, or can be pre-attached prior to assembly into the apparatus. A cover of gift pod container may be alternatively placed into position on top of gift pod container prior to assembly of apparatus, or can be placed on top of food item/stand assembly in the same manner by which a cover is applied as shown and described herein.
Other embodiments include various release mechanisms, actuators, and the like for delivering the concealed item inside a cake or other food item.
Particular examples of the release mechanism include a vertical member 930 and a perpendicular horizontal member 932 removably caught against the assembly as illustrated in
The food item/stand assembly may be employed in a method for delivering an article to a recipient inside a food item. The method has a staging process, for instance when the article is concealed in a tube inside a food item on a stand. Next, the article is releasably held within the tube; and in an operation stage, a force is applied to the stand to simultaneously release the hold on the article and move the article through the tube to an upper surface of the food item. Depending on the characteristics of the release mechanism/process, including any of the release mechanism examples and embodiments herein, the force may be sufficient to eject the article from the food item.
The food item/stand assembly may also be employed in a method for gifting. The method may employ the stages of the various methods, namely concealing the gift in a tube inside a food item on a stand; releasably holding the gift within the tube; and applying a force to the stand to simultaneously release the hold on the gift and move the gift through the tube to an upper surface of the food item. In a stage, the food item on its stand may be presented to a gift recipient.
The food item/stand assembly may also be employed in a method for preparing a food item. The method may employ the stages of the method, namely concealing an article in a tube inside the food item on a stand; and releasably holding the article within the tube. In a stage, preparation(s) (such as decorating, organizing, or assembling) may be conducted on the food item on its stand. A further stage may be employed to apply a force, for example through a compressed spring, to the stand to release and move the gift through the tube to an upper surface of the food item.
One skilled in the art will appreciate that, although the embodiments disclosed herein are described in the context of a food serving system, the food item may be prepared on the serving system. For example, a cake being served on the plate of the serving system may also be decorated thereon. In addition, although the embodiments disclosed herein are described in the context of a system for serving food, the system may be used presenting other non-food-items. For example, the pate of the system may also be used to present small gift items or the like.
