3 Claims. 1

"The invention relates to dishes or food receptacles more particularly designed for use in the serving of young children, and fit is the object of the invention to obtain a construction of dish which when placed upon a table or other support will be retained "thereto against displacement by the child.

To this end the invention consists in the construction as hereinafter set forth.

In the drawings:

Fig. 1 is a plan view of the dish;

Fig.2 is aside elevation thereof;

Fig. 3 is a vertical cross section on line 13-3, Fig. l partly in elevation;

Fig. 4 is an elevation of the vacuum cup detached from the plate;

Fig. 5 is a cross section on line 5--5, Fig. 4; and

Fig. 6 is a view similar to Fig. :3 showing the unsupported dish and vacuum cup.

For .the serving of food to young children, it is desirable to hold the dish from displacement by the child. At the same time it is advantageous to have a construction which can be placed in any desired position on a table or other support to be temporarily retained in such position but capable of being easily removed when necessary.

My invention accomplishes such purpose by an adherent dish of the following construction. A is the dish or food receptacle which may be formed with either a single or a plurality of compartments. At the periphery of this dish and preferably integral therewith is a flange B shown as of return bend cross section and which extends downward below the bottom C of the dish. Beneath the bottom 0 and enclosed within the flange B is a suction cup D formed of resilient material such as rubber. This cup is centrally apertured to receive a lug E depending from the bottom of the dish to hold the cup concentric therewith. In normal position the height of the cup is greater than the vertical dimension between the bottom C and the plane of the lower end of the flange B. Thus when the dish is placed on a table or other supporting plane and is pressed downward to contact the flange B with said plane, the suction cup will be evacuated and, therefore, when released will adhere to said supporting plane. To hold the dish to the suction cup, the latter is preferably duplex having in addition to the downturned cup portion D an upturned cup portion D These may be either separate from each other or preferably as shown have their chambers connected by the channel D and to the supporting plane.

the dish will only increase the force of adhesion so that :it will be adifiicult or impossible for the which forms the socket for receiving the lug E. This lug, as shown, has grooves E in its periphery to maintain constant air connection between the two cups.

With the construction thus far described the vacuum cup D will be frictionally held on the lug E and thereby retained "by the dish. After the food is placed in the dish the latter may be carried to the :table. or to the tray of a high chair. and by then pressing downward both cup portions will be vertically collapsed until the flange B rests upon the supporting plane. Upon release of the downward pressure the resiliency of the walls of the cups will elongate "the same vertically to cause adhesion both to the bottom of the dish Any effort to lift child to remove the plate from the position in which it is placed.

' .In order that the plate may be easiiy removed when it is desired to do so, I preferably provide the lower cup portion D with a radial extension D :constituting a handle. This when lifted will raise the portion of the cup D immediately adjacent thereto, which will break the seal permitting air to fill the chambers of both cups and thus opposite side from the child to be out of his sight and thus prevent tampering with the handle. It ;is therefore apparent that while the dish will be 'non-displaceable by the child it can be easily removed by the attendant. Also the cup D may be easily removed from the lug E when the r dish is to be washed, the grooves E assisting in breaking the vacuum.

To insure that the handle D of the cup is always placed opposite the opening B in the flange A, the lug E is preferably of a cross section which can be placed in only one position within the central recess of the cup as, for instance, indicated in dotted lines in Fig. 1 of the drawing. Thus there is one portion E which projects slightly beyond the periphery of other portions to engage a corresponding channel in the recess and to hold the cup against rotation with the handle D opposite the opening B.

The dish A is preferably formed with tapering having an opening in one side thereof, and a suction cup having upwardly and downwardly facing cup portions and a central recess, said cup being beneath said bottom portion and biased to extend below said peripheral flange with said lug frictionally engaging said recess and being adapted when placed on a supporting surface to evacuate both cup portions by a downward pressure on said dish to contact said peripheral flange with said surface and to thereafter adhere both to said bottom and said surface, said cup being concealed by said flange and having a vacuum breaking handle projecting from one of the cup portions thereof accessible through the opening in said flange.

2. A dish having a bottom portion With a centrally depending lug, and a peripheral flange extending below the lower surface of said bottom portion upon opposite sides thereof, said flange having an opening in one side thereof, and a suction cup having upwardly and downwardly facing cup portions and a central recess, said cup being beneath said bottom portion and biased to extend below said peripheral flange with said lug frictionally engaging said recess and nonrotatively positioned therein, said cup being adapted when placed on a supporting surface to evacuate both cup portions by a downward pressure on said dish to contact said peripheral flange with said surface and to thereafter adhere both to said bottom and to said surface, said cup having a vacuum breaking handle projecting from one of the cup portions thereof which is held in registration with the opening in said flange by the non-rotative engagement of said lug with said central recess.

3. A dish having a bottom portion with a centrally depending lug, and a peripheral portion extending below the lower surface of said bottom portion upon opposite sides thereof, and a suction cup having upwardly and downwardly facing cup portions and a central recess, said cup being beneath said bottom portion and biased to extend below said peripheral portion with said lug frictionally engaging said recess and non rotatively positioned therein and being adapted when placed on a supporting surface to evacuate both cup portions by a downward pressure on said dish to contact the peripheral portion with said surface and to thereafter adhere both to said bottom and to said supporting surface, said lug and central recess being relatively fashioned to form when engaged an unobstructed channel therebetween for the free passage of air between said cup portions.
