The present invention relates to a multi-tier flowable food fountain and methods, and is more particularly concerned with a sanitary chocolate fountain comprising a vertical sleeve with shoulders to support the tiers.
It is well known in the art to have various types of fountains accommodating fluids. More specifically, fountains for eatable viscous fluids such as chocolate have been commercialized since approximately 1995. A typical chocolate fountain where the melted chocolate goes up from a heated bowl via a hidden conveyor screw to then fall in a cascade, curtain-like or waterfall manner back into the heated bowl offers innovative, ornamental and functional characteristics for banquets and the like. For example, a user can after putting a fruit on a fork, bring the fork under the cascading fluid chocolate falling in-between the stages of the fountain for chocolate enrobing before consumption. The former fountains on the market presented tiered-trays, platforms, stages, skirts, landings or brims maintained in place by nuts and bolts or other method using conventional attachment means.
Other apparatuses found in the art include U.S. Pat. No. 3,451,622 issued to Forney on Jun. 24, 1969 uses two tubes of different diameters. U.S. Pat. No. 3,691,787 issued to Kaufmann on Sep. 19, 1972 presents a beverage fountain where the intermediate receptacle is supported on a shoulder at the upper end of the sleeve, whilst the intermediate receptacle supports the upper receptacle. Similarly, U.S. Pat. No. 3,713,583 issued to Gruber on Jan. 30, 1973 has a second beverage bowl mounted directly on the cover post. U.S. Pat. No. 3,722,816 issued to Stewart et al. on Mar. 27, 1973 discloses a retractable fountain assembly using telescoping conduit sections. U.S. Pat. No. 4,026,417 issued on May 31, 1977 to Streim et al. discloses a display stand where each combination of platform and sleeve rests on a guard plate. U.S. Pat. No. 4,099,627 issued to Strada on Jul. 11, 1978 presents a arrangement for displaying articles where the plurality of elements are stackable one onto another, i.e. where the abutment shoulder is part of the element itself. In another aspect of the invention, a plate is fixed on the shaft by a cotter pin. U.S. Pat. No. 4,678,089 issued to Lang on Jul. 7, 1987 presents a display stand where the goods carriers are held in place using a wedge engagement sleeve. Successive sections of the carrier column are further fitted together telescopically. U.S. Pat. No. 4,847,461 issued to Gilmore on Jul. 11, 1989 shows a stackable plate arrangement for microwave dishes where a plurality of support units is used. Similarly, a plurality of support posts are used in U.S. Pat. No. 4,964,520 issued to Kilmartin, III on Oct. 23, 1990. U.S. Pat. No. 6,123,206 issued to Zaremba on Sep. 26, 2000 presents a removable display attachment with wedgelike retainers for vertical rigid cylindrical supports. O-rings and other types of wedge retainers are shown. U.S. Pat. No. 6,681,684 issued to Chen on Jan. 27, 2004 provides for tapered sections interengaging each other.
Accordingly, there is a need for an improved multistage or multi-tier flowable food fountain.
It is therefore a general object of the present invention to provide an improved multi-tier flowable food fountain apparatus.
An advantage of the present invention is that the multi-tier fountain apparatus provides for an enjoyable and self-operating way of entertaining guests.

As shown in
The upper section 60 includes a elongated post 62 which defines opposed first and second longitudinal ends 64 and 66 respectively and a passageway 68 extending longitudinally there between. The first longitudinal or lower end 64 defines an inside diameter 70, preferably continuous within the post 62, and a first outside diameter 72. The lower end 64 is mounted onto the recipient 24 via a generally circular and hollow post mounting base 74 secured onto the interior cavity 28 of the recipient 24 adjacent the apex region 29. As shown with more details in

A conveyor mechanism 130 shown on
As shown on
A post extension 170 is provided to vertically elevate the display of the fountain apparatus 10. The post extension 170 axially extends from the lower end 64 of the post 62 and is connectable to the post mounting base 74 of the recipient 24 in the same manner the lower end 64 may engage the same post mounting base 74 and as earlier described. The post extension 170 has an extension passageway 172 extending longitudinally there through. As one skilled in the art will understand, the extension passageway 172 is substantially an extension of the passageway 68 of the post 62 for a connection during operation with the conveyor mechanism 130. The post extension 170 preferably has the same inside diameter 70 as the post 62 and the same first outer diameter 72 as the lower end 64 of the post 62. An upper portion (not shown) of the post extension 170 is preferably similar to the top section 78 of the post mounting base 74 to ensure appropriate engagement with the lower end 64 of the post 62.
As shown in
The material used to manufacture most parts of the apparatus 10 shall comply with the Food and Drug Administration Regulations. Accordingly, the recipient 24, the post 62, the tiers 110, conveyor mechanism 130, the recipient guard 150, the post extension 170 and most other parts are preferably manufactured using standard stainless steel.
Mounting the apparatus 10 should be done with relative ease for someone skilled in the art. The stand 22 and recipient 24 are usually provided already assembled. The conveyor mechanism 130 is engaged next onto the driving shaft 54 as per the dotted lines of
Operation
Once the apparatus 10 is assembled, the user (not shown) connects the electrical cord 44, turns on the switch 46 to activate the heating element 34. The thermostat can be used to ensure the desired heat is transmitted from the heating element 34 to the heating chamber 36 onto the inner surface 28 of the recipient 24. A desired flowable food media FM such as melted chocolate or the like is poured into the cavity 28 of the recipient 24. When required, the heating element 34 typically heats up the recipient 24 within a predetermined temperature range for maintaining the flowable food media FM within the predetermined temperature range. Then, by switching on the apparatus 10, the user also activated the motor 56 and thereby the driving shaft 54 and the worm screw 132 of the conveying mechanism 130.

It should be understood that the chocolate slightly loses a bit of calorific value while going up the extension passageway 172 and coming down the tiers 110, but gains it back in the heated recipient 24 before starting a new cycle. Furthermore, chunks of chocolate could easily be added in the melted chocolate FM for example. The chunks might not go through the inlet openings 82, but continuous suction towards the passageway 68 or extension passageway 172 combined with the warmth of the food media FM in the recipient 24 will slowly melt those chunks down. The smaller chunks can easily follow the same cycle as presented before, provided the openings 184 are large enough, and offer further amusing entertaining to the guests of the user. Pieces of fruits such as blueberries or the like can be thrown into the recipient 24 or into the passageway from the upper end 66 for various entertaining reasons, although it should be understood that fruits will not melt down.
