Abstract
A place mat, coaster or the like possessing exceptional anti-skid characteristics comprises a planar base member, such as paper or plastic sheet, provided on the top and bottom surfaces thereof with a plurality of arrayed, discrete, spaced-apart projections of a high friction material. Such place mats, coasters and the like are produced by imprinting the aforementioned high friction material in the desired pattern or array on the top and bottom surfaces of the base member.
Claims2
An article useful as a place mat, coaster or the like comprising:
- a flat or planar sheet of paper;
- a plurality of discrete, spaced first projections extending from the top surface of said paper, said first projections consisting essentially of foamed thermoplastic polymeric material providing a high coefficient of friction;
- a plurality of discrete, spaced second projections extending from the bottom surface of said sheet of paper, said second projections consisting essentially of foamed thermoplastic polymeric material providing a high coefficient of friction;
- said first and second projections being substantially integral with said top and bottom surfaces, respectively, of said sheet of paper and being arranged and aligned as illustrated in FIGS. 2 and 3, respectively, of the drawings.
