Serving tray

A serving tray for carrying a plurality of drinks, comprising a top side, a bottom side, and a periphery,

• wherein the top and bottom sides are generally parallel to each other, the top side being planar so as to support the plurality of drinks on the tray and the bottom side being arranged to carry the tray by hand,
• wherein the tray has a center of gravity and an axis extending through the center of gravity substantially perpendicular to the top and bottom sides,
• wherein the bottom side has a relief comprising first and second gripping structures each generally surrounding the axis, the first gripping structure being recessed and providing a first radially inner gripping surface, and the second gripping structure being recessed and providing a second radially inner gripping surface,
• wherein the first and second gripping structures are configured as concentric rings such that sections of the first and second inner gripping surfaces are located diametrically opposite each other at first and second radial distances with respect to the axis, respectively,
• and such that in plural azimuthal positions around the axis, the ratios of the first and second radial distances of the respective opposite sections are equal;
• and
• wherein at least one of the first and second gripping structures is asymmetric in radial cross section, having first and/or second inner gripping surfaces with a radially inner slope that is relatively steep and extends in a slope from the bottom side away from the axis, and a gripping structure top surface, further from the axis than the inner gripping surface, having a radially outer outward slope that is relatively small and extends away from the inner gripping surface in a slope toward the bottom side.

• wherein the top and bottom sides are generally parallel to each other, the top side being planar and arranged for supporting one or more drinks on the tray and the bottom side being arranged to carry the tray by hand,
• wherein the tray has a center of gravity and an axis extending through the center of gravity substantially perpendicular to the top and bottom sides,
• wherein the bottom side has a relief comprising first and second gripping structures formed as recesses in the bottom side, each generally surrounding the axis, the first gripping structure being recessed and providing a first radially inner gripping surface, and the second gripping structure being recessed and providing a second radially inner gripping surface,
• wherein the first and second gripping structures are configured as concentric rings such that sections of the first and second inner gripping surfaces are located diametrically opposite each other at first and second radial distances with respect to the axis, respectively,
• and such that in plural azimuthal positions around the axis, the ratios of the first and second radial distances of the respective opposite sections are equal;
• and
• wherein the first and second gripping structures each are asymmetric in radial cross section, having first and, respectively, second inner gripping surfaces with a radially inner slope that is relatively steep and extends in a slope from the bottom side away from the axis, and a gripping structure top surface further from the axis than the inner gripping surface and having a radially outer outward slope that is relatively small but distinct from being parallel to the bottom side, and extends away from the inner gripping surface in a slope toward the bottom side.
