BACKGROUND OF THE INVENTION
Field of the Invention
The invention relates to a serving dish for small children featuring exchangeable pictures, which comprises an upper dish with a transparent window and a lower dish and an exchangeable picture carrier situated in between.
Pictures or motifs on food bowls are a known feature intended to stimulate a child's appetite and motivation to eat. In many of these dishes the picture on the surface of the bowl will soon wear off or be destroyed by the child's manipulations or cutlery.
U.S. Pat. No. 2,861,367 to Chanslor describes a serving dish for children which is configured as a plastic bowl with a window in the bottom area. Its outer periphery is provided with three supporting legs, each exhibiting a slot on the inner face at half height. In the slots of the three legs a circular picture carrier or disk is guided, which is supported on a central pin on the underside of the bottom of the plastic bowl. The picture disk contains a series of pictures which can be viewed through the transparent window in the plastic bowl.
U.S. Pat. No. 2,514,094 to Rubin discloses a child's serving dish where a bowl to be filled with water is provided as a lower part, which by means of lateral recesses on its inner rim can be firmly connected with an upper part exhibiting corresponding projections on its outer rim. The upper part has a central opening via which the lower part may be filled with water to keep the meals warm. A tubular rotary element penetrates through the central opening of the upper part, with a picture carrier fastened to its bottom end. The top end of the tubular rotary element is plugged with a stopper, which is provided with a turning knob projecting above the surface of the dish. By means of this turning knob the picture carrier can be moved and the individual pictures will appear in the windows on the bottom of the upper part.
The food bowls for children described above have a relatively complicated design and cannot easily be taken apart for cleaning purposes or for exchanging the picture carrier.
BRIEF SUMMARY OF THE INVENTION
It is accordingly an object of the invention to provide a child's serving dish, which overcomes the above-mentioned disadvantages of the heretofore-known devices and methods of this general type and which is a simplified version thereof, and where the dish is easy to clean and the picture carrier is easy to replace.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the figures of the drawing in detail and first, particularly, to FIGS. 1 to 3 and 8 thereof, there is shown a first embodiment of a serving dish according to the invention. An upper dish 1 is attached to a lower dish 3 by way of a central fastening element. Here, the fastening element is an axle pin 7. Beneath the upper dish 1 there is an exchangeable picture carrier 4 held by the axle pin 7. The terms “picture carrier” and “pictures” should be understood in their broadest sense, as including any suitable optical and visual stimulus. As such, various pictures, comics, lines of text, or stories may be printed on the picture carrier 4. A recess 8 or indentation on the periphery of the upper dish 1 permits the turning of the picture carrier 4. The pictures 5 may be viewed through a transparent window 2 in the upper dish 1. In its main intent, the pictures or other content on the picture carrier 4 thus viewed will stimulate the child to eat. It is also possible to provide two independently turnable picture carriers whose pictures 5 complement each other in the transparent window 2.
It is furthermore possible to attach parts of the pictures firmly to the underside of the transparent window 2, which will be complemented by other parts of pictures on the movable picture carrier 4 to form a complete picture 5. The pictures could for instance by resolved into pixels with part of the pixels on the transparent window and the other part on the movable picture carrier 4, such that the whole picture will only be recognized when the parts overlap.
FIG. 2 shows the child's serving dish according to the invention in a section along line II-II of FIG. 1. The upper dish 1 is held in the lower dish by means of the axle pin 7. The picture carrier 4 is situated between the dishes. FIG. 3 shows the exchangeable picture carrier 4 with pictures 5 and an axle opening 6 through which the pin 7 penetrates.
FIG. 4 to 7 present the second embodiment of the serving dish according to the invention, with FIG. 4 showing the transparent window 10 through which the picture carrier 12 with its various pictures 13 can be seen. FIG. 5 shows the serving dish in a section along line V-V. The upper dish 9 has at least one transparent window 10 and locks into a groove 16 of the lower dish 11 by means of a rim 15 on its bottom. The lower dish 11 is provided with a recess 14 (FIG. 7) which guides the picture carrier 12 configured as a strip. The child may draw the picture carrier through the recess 14 whereby various motifs, comics or stories are presented in the transparent window—as in the first embodiment of the invention. FIG. 6 shows the picture carrier 12 with different pictures 13.
In the second embodiment the pictures may also be resolved into pixels, with part of the pixels attached to the transparent window 10 and the other part to the movable picture carrier 12, such that a readable text or a recognizable motif will only appear when the two parts overlap.
FIG. 8 illustrates a variation of the embodiment of the serving dish illustrated in FIG. 2. The central fastening element 7 is configured as a tubular axle pin that is held within a central opening formed in the lower dish 3. The central fastening element 7 is an integral part of the upper dish 1. Further, the upper dish 1 and the lower dish 3 are provided with mutually adjacent second fastening elements 17, e.g., engaged interlocking means, disposed concentrically to the central fastening element 7, to establish a torque proof connection between the upper dish 1 and the lower dish 3.
In both embodiments the lower dish 3 may be configured so as to be non-slipping or the bottom may be provided with a fastening means such as a suction cup.
