A portable mat which keeps itself clean teaches a combination of nine upper surface panels of hard rubber, EPDM, hard neoprene, a very durable bottom surface/substrate holding the mat panels, which may be the neoprene in unitary body embodiments or a separate material in other embodiments, a formula for placement of the panels upon the substrate, a specific folding sequence, and a tenth mud-flap outside of the regular 3×3 pattern of the other nine panels which completes the folding sequence with every bottom surface covered by another bottom surface and no top panel in contact with any bottom surface. A handhold at one corner and indicia on the top surface assist the user in properly folding, as do the formulaic gaps which allow tight proper folding and prevent improper folding.

An apparatus may include a first layer that includes a plurality of inlets and a surface feature; a second layer, where the surface feature opposes the second layer; an outlet, and a pattern defined on at least one of the first layer and the second layer, where the pattern defines a suction path from each inlet of the plurality of inlets to the outlet.

Reversible floor mats having two layers bonded together at an undulating surface are described. Each layer has a generally non-constant across over its width and length. The combined thickness of the two layers is generally constant over its width and length. The layers have different colors and/or different surface textures to provide different working surfaces.

A system and method of training or modifying the behavior of pets and, in particular, dogs is disclosed and may include using scratch-resistant protector having adhesive and/or additive to protect the integrity of a door or other object. The adhesive may generally provide a securing or coupling relationship between an object and protector. The additive may provide a material that canines find unpleasant to smell, taste, touch, and/or scratch. In some implementations, the additive may be reapplied (e.g., if it wears off and/or otherwise diminishes in strength, quantity, quality, and/or overall effectiveness).

An apparatus may include a first layer that includes a plurality of inlets and a surface feature; a second layer, where the surface feature opposes the second layer; an outlet, and a pattern defined on at least one of the first layer and the second layer, where the pattern defines a suction path from each inlet of the plurality of inlets to the outlet.

A protective film includes a base layer and a wear layer, the wear layer comprising a UV cured hardcoat resin, and the UV cured hardcoat resin comprising surface modified silica nanoparticles. The protective film may comprise a pressure sensitive adhesive for adhesion to a floor. The protective film may be used, for example, as a protective floor finish.

A container skate of synthetic material facilitates movement of a container. A sliding body has two inclined ends facilitating sliding of the body in opposite directions with a container thereon without further damage to the container or support surface over which it is moved. The body has an upstanding plug extendable into a container corner fitting so pulling of the container draws the body with it, sliding over a surface while bearing container weight. The body further includes a stop member extending therefrom and spaced from said plug.

A drop cloth retention system includes a drop cloth that may be positioned on a support surface. Thus, the support surface is protected from being contaminated. A clamping unit is provided and the clamping unit may be positioned on the support surface. The clamping engages the drop cloth such that the drop cloth is inhibited from moving on the support surface.

A multi-component floor mat has a base or frame layer, intended to be positioned on the floor, that is dimensioned to accommodate a flexible textile mat or rug top layer portion that is releasably held in place on or in the base or frame layer by an attachment coupling feature associated with one or both portions, thereby allowing for the easy removal or replacement of the textile top layer of the mat and its economical laundering.

A chair mat including a body having a perimeter. The perimeter is defined by a rear linear portion disposed opposite an arcuate lip portion, left and right rear arcuate portions separated by the rear linear portion, a left front arcuate portion separated from the left rear arcuate portion by a left linear portion, a right front arcuate portion separated from the right rear arcuate portion by a right linear portion, a left arcuate inwardly projecting portion separating the left front arcuate portion and the arcuate lip portion, and a right arcuate inwardly projecting portion separating the right front arcuate portion and the arcuate lip portion.
