Abstract
A container having a surface including at least one high friction surface region having a coefficient of friction of between about 0.63 and about 2. Optionally, the at least one high friction surface region includes a coating layer, which may include fibers. The surface of the container may further include at least one low friction surface region having a coefficient of friction of less than 0.5, or preferably less than 0.3.
Claims7
A container comprising:
- a rectangular body having an outer surface;
- and
- a hinged lid having an inner surface, the hinged lid being attached to the rectangular body so as to be movable between opened and closed positions;
- wherein the rectangular body and the hinged lid are formed of a sheet material and wherein the outer surface of the rectangular body and/or the inner surface of the hinged lid comprise at least one high friction surface region having a coefficient of friction of between about 0.63 and about 2 such that the at least one high friction surface region increases friction between the rectangular body and the hinged lid so as to substantially prevent inadvertent opening of the container,
- wherein the at least one high friction surface region comprises a coating and the coating comprises fibers accounting for about 10 percent to about 30 percent of the total weight of the sheet material in the high friction surface region.
