A non-skid surface for containers having a generally planar base layer with an upper surface, a lower surface, and a surface area. A plurality of bumps are disposed spaced apart over and projecting upward relative to the upper surface over a substantial portion of the surface area of the base layer. The bumps are shaped and arranged to accept a container placed on the non-skid surface such that a support rim of a bottom of the container registers between bumps and rests solely on the upper surface of the base layer. The bumps are shaped and arranged to accept a container in this manner in a plurality of positions over the surface area. A method of forming the non-skid surface can include selecting at least a size and a shape of a first container bottom rim. A plurality of first container rim locations are plotted in a first repeating location pattern of a desired spacing. Each of the plurality of first container rim locations corresponds to the first container bottom rim size and shape. A plurality of protrusions are provided on a surface and are positioned and arranged spaced apart over and projecting upward from the surface over a substantial portion of the surface area. The plurality of protrusions are arranged in a repeating bump pattern that corresponds to the first repeating location pattern so as not to overlie the plurality of first container rim locations. |
