Preferably, height D of tray rim 114 is sufficient to prevent either or both multiple beverage containers 101 and multiple food containers 102 from falling off serving tray 100, as either or both multiple beverage containers 101 and multiple food containers 102 are carried from areas of their preparation to patrons in a beverage and food service venue. Preferably, tray rim 114 is sufficiently flared outwardly at the top of tray rim 114, as shown, so that when either or both multiple beverage containers 101 and multiple food containers 102 are dropped near outer edge 128 of serving tray 100, dropped beverage containers 101 and multiple food containers 102 tend to be collected onto serving tray 100.
Tray thickness G of tray platform 104 preferably does not exceed a thickness that creates an excessive total weight of serving tray 100, as shown, but preferably provides the desired non-skid, structural, sound absorbing, and thermal insulating characteristics. Preferably, when coupled with the intrinsic structural, intrinsic sound absorbing properties, and intrinsic thermal insulting properties of materials of tray platform 104, resulting tray thickness G is no greater than about ¼ inch or no less than about ⅛ inch. More preferably, tray thickness G is about 3/16-inch thick, as shown.
Preferably, anti-skid material 115 has anti-skid surface 112 and constitutes a minor contribution to total tray thickness G, as shown (see FIG. 4). More preferably, anti-skid material 115 is a patterned film, having a high friction coefficient, hydrophobic and scuff-resistant surface properties, which can be laminated to, and which exhibits a high degree of adherence to, other materials that make up tray platform 104, as shown. Preferably, anti-skid material 115 is a high friction coefficient, hydrophobic, scuff-resistant polymer film, more preferably Shore A durometer range 35-85, neoprene rubber polymer film. Alternately preferably, non-skid material 115 is a high friction coefficient, hydrophobic, scuff-resistance polymer silicone or fluorocarbon film. Upon reading this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as friction coefficient, hydrophobic properties, scuff-resistance, film lamination, etc., other materials, such as acrylics, Nitrile®, ethylene propylene rubber, thermalplastic elastomers, etc. may suffice.
Preferably, structural material 123, sound absorbing material 116, and thermal insulating material 118 together provide desired characteristics of tray system 100 and comprise a composite of two or more materials 127, as shown. Preferably, anti-skid material 115 and such composite of two or more materials 127 are laminated into a single structure that constitutes tray platform 104 with tray rim 114, as shown.
Preferably, structural material 123 is formable, bondable, light weight, and stiff. Preferably, structural material 123 comprises aluminum, preferably the 6000 series of heat-treatable aluminum alloys. Upon reading this specification, those skilled in the art will now appreciate that, under appropriate circumstance, considering such issues as formability, bondability, lightness of weight, stiffness, structural strength, etc., mild steel, 5000 series of aluminum alloys, fiberglass mash, carbon whisker mash, etc. may suffice.
Preferably, sound-absorbing material 116 is a low-density polymer. More preferably, sound absorbing material 116 is bondable to structural material 123, bondable to anti-skid material 115, and a low-density acoustic foam polymer, preferably low density phenolic, melanine, or formaldehyde resin based acoustic foam polymer. Upon reading this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as sound absorbing characteristics, bonding strength to structural materials and to anti-skid materials, etc., other porous structures such as foams, honeycomb, etc., may suffice.
Preferably, thermal insulating material 118 is a low-density polymer. More preferably, thermal insulating material 118 is bondable to structural material 123, bondable to non-skid material 115, and low density thermal insulating foam polymer, preferably low-density phenolic, melanine, or formaldehyde resin-based thermal insulating foam polymer. Upon reading this specification, those skilled in the art will now appreciate that, under appropriate circumstances, considering such issues as thermal insulating characteristics, bonding strength to structural materials and to non-skid materials, etc., other porous structures, such as corrugations, honeycomb, etc., and other materials, such as ethylene copolymer, expanded polyethylene, polycarbonate, polyester, polyether, polyetherimide, polyimide, polyolefin, polypropylene, polyurea, and vinyl, etc., may suffice.
FIG. 9 shows a bottom view of a serving tray, according to another preferred embodiment of the present invention. As shown in this alternate preferred embodiment, grippers 190 are preferably angled at an about forty-five degree angle relative to the orientation of cradle 124, as shown. Providing the two grippers in such an orientation allows both right-handed and left-handed servers to ergonomically utilize serving tray 100.
Although applicant has described applicant's preferred embodiments of this invention, it will be understood that the broadest scope of this invention includes modifications such as diverse shapes, sizes, and materials. Such scope is limited only by the below claims as read in connection with the above specification. Further, many other advantages of applicant's invention will be apparent to those skilled in the art from the above descriptions and the below claims.
