Abstract

ABSTRACT OF THE DISCLOSURE
A serving plate set having two similar receptacles which in one form is separated by a sealing member that segregates the receptacle contents, such member also being of a plate-like configuration and which in another form employs the two receptacles to create a closured container.

Description

1~)840(}7 ~P- 8219 -M26 SERVING PLA_E SET OR THE LIKE

This invention relates to a serving pl~te set, the eLements of which are adspted for intereng~gement so that in st least two assembled forms it also functions as a cLosured contsiner, one of which further provides for sepArate compartmental food s~orage section~.
More psrticul~rly, therefore, the serving plate set functions in a dual capacity whereby the food contained therein c~n be sppropriately consumed from the contsiner elements themselves. The plate set construction further contempl~tes the use of two ~imiLarly shsped ~nd sized receptacles, each separately sealable by a sealing member posltioned between them so that the contents of e~ch receptscle is segreg~ted from the other. The concept al90 incorporAtes a8 a feature thereof the ~ppropriate ~hsping of the center w~ll area of the sealing member such that it csn sl~o be used as ~ plate should it be so deslred to do 90.
Prior art contsiner~ hsve, of course, incorporeted receptacle *nd closure elements that are constructed in f~shion to permit their us~ge a8 pl~te members. However, such designs and constructions have not contemplated the employment of ~ common seal which could be used to simultsneously be u~ed between to sesl separate receptsbles, Accordingly, such do not provide suitable mesns for the storage of different consum~bles in the sesl and the receptflcle elements.
The in~tant construction, therefore, sffords the user a device which is multif~cted in nature and thus will minimize his need for 8 w riety of different ~erving ~nd storage dishes, container~ and plates. Similsrly, either 1~)84007 of the receptacle members may be used alone with the sealing ' member until additional storage capacity is required. This single receptacle usage, of course, minimizes the space requirements used in such food storage. Likewise, the receptacles of the set may be employed without the common seal to produce a container of increased capacity.
Thus, in accordance with the present teaching, a plate set is provided which comprises a first plate having a bottom wall and upstanding peripheral walls ter-minating at an upper edge, a seal plate having a top walland integral downwardly extending peripheral walls ter-minating at a lower edge, a flange integral with and ex-tending outwardly from the lower edge, a first rim wall integral with and extending downwardly from the flange, and a second rim wall integral with and extending upwardly from the flange. The upper edge of the first plate . i8 engaged in a liquid tight seal against the inner face of the first rim wall with the first plate and seal being separable from each other and a second plate having a bottom wall and upstanding peripheral walls terminating at a second upper edge which edge fits snugly against the inner face of the second rim wall.
These and other objects and advantages of the invention will become more apparent from the following detailed description of a preferred form of the invention when taken in conjunction with the drawings wherein:
Fig. 1 is an exploded perspective view of one form of the serving plate set of the present invention;
Fig. 2 is a top perspective view of the invention of Fig. 1 shown in assembled form;

,...
- ~ - 2 -Fig. 3 is a top plan view thereof;
Fig. 4 is a side elevational view of the assembled serving plate set with a partial cross-sectional showing taken along line 4-4 of Fig. 3;
Fig. 5 is an enlarged cross-sectional view taken of the circled segment 5 of Fig. 4; and Fig. 6 is an enlarged cross-sectional area similar to the circled segment 5 of Fig. 4 except that the common seal therebetween has been removed.
The serving plate set of this invention generally indicated in Fig. 1 by reference number 10 includes a first receptacle or plate 12, a second receptacle or plate 14, and a common seal member 16 which in assembled form (Fig~ 2) produce a segmented container having two separate and distinct storage compartment sections.

- 2a -1'~840t)7 While each of these elements 12, 14 and 16 are illustrated as being semi-ovate in shape, it should be understood that nuch may take any other suitable shape depending upon the contemplated end usage of the device.
Each of the basic plates or receptacles 12 and 14 are of a similar structural arrangement and respectively incorporate bottom walls 18 and 20, and upstanding peri-pheral sidewalls 22 and 24, which terminate in first and second upper edges 26 and 28.
Sealing number 16 is formed by a dish shaped central wall, _,32 and incorporates a peripherally extending flange 38 which is integral therewith and from which de-pend a downwardly extending rim 34 and an upstanding peripheral rim 36. As is apparant in Figs. 4 and 5, the subject rims 34,36 are slightly offset with respect to one another, and such relationship produces very desirable re~ults which are more fully discussed herein-after. Likewise, note that rims 34,36 incorporate inside faces 40, 42 which sre slightly slanted and are adapted to firmly engage against the exterior surfaces of upper edges 26 and 28 in a liquid seaLing fsshion.
The respective~ serving plates 12 and 14 also vary slightly in their respective depths and the upper edge 28 of plate 14 is positioned and flared outwardly such that the teLminus of its outermost extent is of a greater peripheral extent than that of the serving plate 12.
This produces several desirable effects, especially in the sealing of each of the respective receptacles by sealing member 16. Note in particular (Fig. 5) that each of the serving plates are sealed along the outer surfaces of their upper edges 26 and 28. Accordingly, 400~

because the peripheral extents of these upper edges are of a different magnitude, the mentioned upper edges 26 snd 28 are slightly offset. Accordingly, when sealing member 16 is in its assembled position, the sealing pressure applied by each of these respective edges 26, 28 is translated through that sealing member in bending moment fashion to produce an even better sealing effect on each of the respective outer surfaces.
Such bending moment forces are, of course, im-proved because of the extent of the lever arm provided within flange 38. Accordingly, the pressure applied between edge 26 and rim 34 tends to produce an upward movement of flange 38 ~n a pivotal fashion around point A. This, in turn, tends to move the rim 36 inwardly and into a better msting engagement with the outer surface of upper edge 28. Likewise, the sealing pressure developed between upper edge 28 and rim 36 tends to produce a similar action which deflects the rim 34 into even better sealing engagement with upper edge 26 of the serving plate 12.
Preferably, the plates or receptacles 12, 14 are formed from rigid plastic materials such as hi~h den8ity polyethylene or polypropelene, while the separating seal member 16 is preferably formed of low density poly-ethylene materials. These particular ma~erial combinations, as will be appreciated, improve the sealing effect obtained between the respective members and further assures that a liquid tight seal is maintained therebetween.
Furthermore, it should be appreciated that the design and construction of the instant serving plste set (Fig.6) enables the user to selectively employ only the plates 12 and 14 in the storage of foodstuffg. This is accomplished ~ 40()7 again by employing the difference in peripheral extents of upper edges 26 and 28. Accordingly, the upper edge 28 canbe slipped over the upper edge 26 in a fashion such that the two serving plates will be s~curely engaged one with respect to the other in a closuring fashion.
Thus, should it be desired not to use the sealing member 16, these two plates alone can be employed to effectively containerize appropriate foodstuff products. Likewi~e note that depending upon the quantity of consumables to be stored, either of the plates 12, 14 may be employed as the principal receptacle in this interrelated relationship.
While the preferred form of the invention has been described and disclosed above, it is to be understood that such changes and alterations as would occur to those skilled in the art are to be considered within the purview of this invention and to fall within the scope of the appended claims.
