Abstract

A combination and structure of serving tray and dishes wherein between the base areas of the dishes and the upper surface area of the tray are interposed permanent magnet elements secured to one of said surfaces, and thin sheets of magnetic metal secured to the other of said surfaces. In both instances (securing of the magnetic elements and securing of the metal elements respectively) the elements are preferably coated and covered and sealed to the said surfaces by thin coatings or laminations of plastic material.

Claims

1. In combination with a serving tray having at least a substantial supporting area constructed of a magnetic metal and two types of dishes to be supported thereon, conventionally having in use concentrically stacked relation when served, such as cups and saucers, cooperating magnetic dish-retaining means comprising, for each saucer-type dish, an annular upwardly extending recess formed in its base, and a dual-functioNing, permanent annular magnet element embedded in the said annular recess in he base of the saucer-type dish and being substantially concentric with the configuration thereof, and having a diameter somewhat less than the diameter of the base of said saucer-type dish, and comprising for each of said cup-type dish a similar annular recess in the base portion thereof and a magnetic metal annular element embedded in the annular recess in the base portion of the cup-type dish and of substantially similar diameter to said permanent magnet element and disposed concentrically above said permanent magnet element when said saucer-type and cup-type dishes are conventionally stacked and supported upon said tray, the coercive force of said permanent magnet element being adequate to retain said saucer-type dish upon said metallic area of said tray and being also adequate to retain said cuplike dish against slippage or displacement upon said saucerlike dish when stacked as set forth.
