PAP-ER DISH AND BAiSE THEREFOR Herman Carew, Easton, Pa., assignor to Dixie Vortex Company, Chicago, Ill'., a corporation of Delaware Application August 26, 1940, Serial No. 354,290

3 Claims.

My invention relates to new and useful improvements in paper dish and base or support therefor and has for its principal object the formation of the paper dish in such a manner that it will cover the upper surface of the base or support and enclose the edge of the base or support thereby providing a sanitary unit of simple and inexpensive construction.

Another object of the invention resides in the formation of the paper dish in such a manner that a plurality of dishes may be arranged in stacked formation and in which the terminal dish may be removed from the stack by engagement of the base or support therewith, the base or support being provided with fingerengaging openings whereby it may be manipulated for engagement with the paper dish.-

Another object of the invention resides in the formation of the paper dish and base or support in such a manner that the paper dish may be readily held with respect to the base or support to provide a sanitary unit or structure and in which the paper dish, on removal from the base or support, will be so deformed or mutilated that it cannot be used a second time.

With the above and other objects in view, which will appear as the description proceeds. my invention consists inthe novel details of construction, and arrangement of parts, described in the following specification and illustrated in the accompanying drawings, and while I have illustrated and described the preferred embodiments of the invention, as they now appear to me, it will be understood that such changes may be made as will fall within the scope of the appended claims.

In the drawings:

Fig. l is a top plan of thepaper, dish.

Fig. 2 is a side elevation of the paper dish.

Fig. 3 is a transverse section on the line 3-3 of Fig. 1. i

Fig. 4 is a transverse section through the base or support for the paper dish.

Fig. 5 is a side elevation showing a stack of paper dishes. certain of the dishes being shown in cross section, and the position of the base or support, relative to the stack of paper dishes, for removal of the terminal dish, the base or support being shown in transverse section.

Fig. 6 is an enlarged fragmental transverse section showing the manner in which the paper dish is connected to the base or support.

Fig. '7 is a side elevation showing the application of the principles of my invention to a paper cup and cover therefor; and

Fig. 8 isa iragmental transverse section through a paper cup and cover involvin the principles of my invention disclosed in Figs. 1 to 6 inclusive.

In the drawings a denotes generally the paper dish and b the base or support therefor, the base or support being preferably formed of relatively-light metal although it will be appreciated that if desired it might be formed of other suitable relatively rigid material. The paper dish includes the flat bottom I and upwardly inclined flange 2, formed around its peripheral edge with a depending flange 3 having the upwardly and inwardly directed flexible lip portion 4 terminating below the under surface of the inclined flange 2. The juncture of the depending flange 3, with the inclined flange 2, forms a seat 5 for a purpose which will be later described and it will be noted, by reference more particularly to Figs. 2, 3 and 6 of the drawings. that the depending flange 3 is of such a height that it terminates above the plane of the flat bottom I.

The base or support 27, as previously stated, is preferably formed of metal or other relativelv rigid material and includes the flat bottom 6 and upwardly inclined flange portion I terminating in the rounded bead 8 around its edge. Openings 9 are formed in the fiat bottom 6 and the fingers of the user may be engaged therein for manipulating the base or support relative to a stack of the paper dishes.

In Fig. 5 of the drawings I have shown a stack of paper dishes, the dishes being inverted from their normal use position and the base or support is shown above the stack, in inverted position and adapted to be moved into engagement with the terminal paper dish. "The fingers of the user will be placed in the openings 9, of the base or support, and when the base or support is lowered relative to the stack its beaded edge will engage the lip 4 of the terminal paper dish and on further pressure will snap under the edge of the lip and contact the seat 5, as shown quite clearly in Fig. 6 of the drawings, it being understood that the rounded bead 8, formed around the edge of the flange l of the base or support, forms contact with the seat and in,turn will be engaged by the edge of the upwardly and inwardly directed lip I. When the bead 8 is in contact with the seat 5 there is in reality a three-point contact for there is a point of contact with the upwardly directed flange 2, a. point of contact with the depending flange 3, and a point of contact with the edge of the lip 4. By the construction described the p per dish will be held on the base or support against movement relative thereto and after use when the paper dish is removed from the base or support the lip 4 will be so dei'ormed or mutilated that the p p r dish cannot be used a second time. It will, of course, be understood that after the base or support is manipulated to remove the terminal paper dish from the stack that it will be inverted for use. The bottom I of the paper dish will be supported on the bottom Ii of the base or support, and the flange 2 of the paper dish will be supported by the flange I of the base or support. The depending flange 3 and lip l of the paper dish will enclose the beaded edge of the base or support. With this construction the paper dish forms not only a cover for the upper surface of the base or support, but also for the beaded edge thereof and this will prevent the contact of any food with the base or support thereby aiding to maintain the same in a sanitary condition.

With the construction of the paper dish described it will be seen that :the dish is relatively shallow as is also the base or support therefor.

In Figs. 7 and 8 of the drawings I have shown the principles of my invention in connection witha paper cup and cover therefor. The side wall of the paper cup is shown at l and has the beaded edge II. The cover includes the flat top portion I2, depending flange I3 and upwardly and inwardly directed flexible lip I4. In use the cover willbe forced downwardly over the beaded edge of the cup and the lip I4 will be flexed suiflciently to allow the bead to snap past and be received against the seat I5, formed at the juncture of the top I2 and flange I3 interiorly of the cover. It will be noted that the beaded edge I I has what might be termed a three-point contact with the cover, a portion of the bead engaging the under surface of the top I2, a portion of the inner face of the depending flange I3 and the edge of the lip I4, The beaded edge It being snapped to position beyond the edge ofthe lip l4 forms a tight engagement with the cover and the cover is held in its tight closing position, against the beaded edge II, by the engagement of the under side ofthe bead by the lip I as is quite clearly illustrated in Fig. 8 of the drawings. Having fully described my invention what I claim as new and desire to secure by Letters Patent is:

1. In combination with a paper dish including a flat bottom portion having an upwardly inclined flange formed around its peripheral edge with a substantially vertical depending flange having an upwardly and inwardly directed lip at its lower edge presenting a free upper edge portion, a curved seat being formed at the juncture of the upwardly inclined flange and the depending flange, a relatively rigid base or support therefor, said base or support having a beaded edge adapted to contact against the seat formed in the dish and held thereagainst by engagement of the free upper edge portion of the lip under the beaded edge.

2. Incombination with a paper dish including a flat bottom portion having an upwardly inclined flangeformed around its peripheral edge with a substantially vertical depending flange having an upwardly and inwardly directed readily flexible lip at its lower edge presenting a free upper edge portion terminating short of the surface of the inclined flange, a curved seat being formed at the juncture of the upwardly inclined flange and the depending flange, a relatively rigid base or support therefor, said base or support having a beaded edge adapted to contact against the seat formed in the dish and held thereagainst by engagement of the free edge portion of the readily flexible lip against the under surface of the beaded edge.

3. The combination with a, paper dish including, a flat bottom portion having an upwardly inclined flange formed around its peripheral edge with a substantially vertical depending flange having an upwardly and inwardly directed readily flexible lip at its lower edge presenting a free upper edge portion terminating short of the under surface of the inclined flange, a curved seat being formed at the juncture of the upwardly inclined flange and the depending flange, of a relatively rigid base or support adapted to be engaged with the dish by a facewise movement relative thereto, the base or support having a'beaded edge adapted to flex the lip of the dish flange during said facewise movement and to snap to position with the free upper edge portion of the lip engaging the under surface of the bead of the base or support and holding the head in contact with the seat formed in the dish.
