[ 0020 ] fig1 is plan representation of a tray 10 constructed in accordance with the principles of the invention . as shown , tray 10 has a bottom portion 12 surrounded by a peripheral sloping wall 13 . extending outward from the upper portion of peripheral sloping wall 13 is a flange 15 . the dimensions of bottom portion 12 , peripheral sloping wall 13 , and flange 15 are such as to conform to corresponding dimensions of preexisting trays ( not shown ), whereby tray 10 is nestable with , and therefore , stackable upon , the prior trays . in this manner , therefore , restaurants that purchase tray 10 are not required to dispose of their existing inventory of trays entirely , as a gradual phase - out is enabled . bottom portion 12 is provided with a molded - in pattern , which may be in the form of lines 20 , cross - hatching 21 , roughened surface 22 , or any other surface finish that would enhance frictional communication between the food - carrying containers ( not shown ) and beverages ( not shown ) thereon . of course , such a surface finish is itself optional in the practice of the invention , and any other information may be printed on bottom portion 12 of the tray , such as advertising material or an identifying trademark used by the particular restaurant , as is customary in fast food establishments . at the ends of tray 10 flange 15 is shown to extend further outward to form handle regions 25 and 26 . each of handle regions 25 and 26 has an upper surface on which molded - in information 27 and 28 is presented . the placement of molded - in information on the upper surfaces of handle regions 25 and 26 avoids the problem in the art of providing information on peripheral sloping wall 13 , which required the wall to be enlarged whereby the tray is made non - standard , thereby causing disruptions in the service and operation of the restaurant . molded - in information 27 and 28 need not be identical on both handle regions , as shown in fig1 . instead , each of the handle regions can be provided with different information . moreover , such information need not be molded - in , but may be molded to raised or negative relief on the handle regions . it is an advantage of the present invention that placement of the molded - in information on the upper surfaces of handle regions 25 and 26 produces a multi - sensory presentation of the information in that such information is not only visible , but palpable as the tray is carried by the customer . thus , the customer &# 39 ; s attention is drawn to the information which is immediately felt by the customer . thus , such information may contain material presented in braille for assisting visually challenged customers . [ 0024 ] fig2 is an isometric representation of an insert 40 which is one of a pair of such inserts that would be installed in a mold ( not shown ) during injection molding of tray 10 . as shown in this figure , mold insert 40 is provided with a pair of mounting apertures 42 that facilitate the installation of the mold insert to the mold with the use of fasteners ( not shown ). in this specific illustrative embodiment of the invention , mold insert 10 has a sealing edge 44 that has a curvature that corresponds to the outer contour of handle regions 25 and 26 . mold insert 40 has a mold surface 45 into which is made an engravement 47 in the mirror image form of the variable information that would be presented on handle regions 25 and 26 , such as molded - in information 27 or 28 . of course , the molded - in information need not be in the form of an engravement , but may , as stated hereinabove with respect to other embodiments of the invention , be in the form of a raised relief information , whereby a desired form of relief is made in the handle regions . persons of skill in the art would be able to configure the molded - in information to achieve a presentation on the handle regions of the tray of images , logos , trademarks , foreign language characters , raised braille characters , and the like . in the practice of the invention , the molded - in information has a height characteristic that has been determined empirically to provide excellent ergonomic feel while maintaining a high degree of cleanliness . that is , food particles and other substances , such as grease , must not accumulate on or around the molded - in information . additionally , the determined height characteristic must retain its advantageous tactile response and visibility characteristics after repeated usage and washing . in a practicable embodiment , the height ( or depth ) characteristic of the molded - in information is approximately between 0 . 003 ″ and 0 . 008 ″, and preferably between 0 . 005 ″ to 0 . 007 ″. these height / depth dimensions provide good feel , while the tray material stays clean and the information molded thereon remains visible during extended periods of restaurant service . in addition , it is desirable that the molded - in information have an edge contour that serves to preclude accumulation therealong of food particles , greases , and hand oils . thus , the contour , which ultimately depends on the letters and / or logo that form the molded - in information , should not have a deep ridge or corner . in some embodiments of the invention , the molded - in information is textured , while maintaining the height / depth thereof within the advantageous range set forth above . although the invention has been described in terms of specific embodiments and applications , persons skilled in the art can , in light of this teaching , generate additional embodiments without exceeding the scope or departing from the spirit of the disclosed invention . accordingly , it is to be understood that the drawing and description in this disclosure are proffered to facilitate comprehension of the invention , and should not be construed to limit the scope thereof .
a tray for carrying food and beverage in a restaurant has a substantially planar tray bottom portion , and an upwardly extending peripheral sloping wall .
