Abstract
The invention utilizes an absorbent non-woven fabric impregnated on one side with vinyl backing for protecting furniture, floor surfaces, and decks from moisture, grease, or other matter emanating from a potted plant or other item situated upon the invention. The non-woven fabric absorbs and holds the moisture, grease, or other matter in place and promotes evaporation while the vinyl backing provides a non-skid surface and minimizes scratching, staining and damage to the surface underneath the invention.
Description




BACKGROUND OF THE INVENTION




The present invention relates to a new and improved protective mat for insertion between stationary placed items such as potted house plants, potted deck plants, barbeque grills and other items from which water, or other fluids and debris can be spilled, onto floors, table tops, decks and patios.




Mats for potted plants are typically made of non-absorbent materials such as plastic, glass, rubber, cork, etc. In addition, common objects such as plates or trays are used. Such devices and materials have significant shortcomings and disadvantages. The two major disadvantages being that some of these types can scratch or mar the table or floor surface it is placed on and secondly that they are of non-absorbent materials. Consequently, spilled or leaking muddy water can overflow and leak onto the table or floor and damage the surface. In the outdoor setting, such as for decks and patios, often nothing is used in between potted plants or barbeque grills and the deck or patio surface. This can cause damage to the deck or patio surface or create slippery and hazardous conditions.




SUMMARY OF THE INVENTION




This invention was created to solve the two most important shortcomings of mats that may be placed under potted plants or other stationary things that spill or generate moisture or grease or debris on decks, patios, table tops, and floors. One being absorbency, the other being protection of surfaces from scratching, or damage from water, grease or other spilled debris.




The invention utilizes an absorbent non-woven fabric impregnated on one side with waterproof vinyl backing for protecting furniture, floor surfaces, deck surfaces from moisture, grease, or other debris emanating from a potted plant situated upon the invention. The non-woven fabric absorbs and holds the moisture in place and promotes evaporation while the vinyl backing provides a protective non-skid surface and prevents soak through which minimizes staining and damage to the surface underneath the invention.




An advantage and feature of the invention is that the plant coasters may be cleaned in a washing machine and also dried in a clothes dryer.




A further advantage and feature of the invention is that moisture from the potted plant may be absorbed and hidden in the fiber mesh.

DETAILED SPECIFICATION




Referring to

FIGS. 1 and 2

, the invention is shown and is generally designated with the numeral


20


. The invention principally comprises a non-woven fabric


21


impregnated on a first side and a vinyl backing material


22


bonded to a second side.




The non-woven fabric is suitably formed in a conventional garnet machine that provides a uniform layer of randomly meshed acrylic fibers. The layer is then put into a needle loam which mechanically interlocks the randomly meshed fibers by needle punching the fiber into a stabilizing non-woven fabric sheet material that is readily flexible.




While in sheet form, non-woven fabric material


21


is coated with vinyl, to yield the vinyl backing material


22


on the second side. The vinyl backing material


22


is cured before further processing. In one embodiment, the vinyl backing material


22


is cured by heat from a gas-fired oven.




The fabric sheet is then cut to the finished size and shape which is circular in the preferred embodiment. Edge stitching


23


provides reinforcement and protection to the finished edge.




The vinyl backing material


22


is waterproof, functions as a moisture barrier for protection of the surface


25


underneath the invention and operates as a non-skid surface. The non-woven fabric


21


is absorbent and is capable of moisture dispersion and accelerating evaporation. Moreover, the fabric absorbs grease, moisture, and food without becoming slippery.




When used as a plant coaster


20


, the invention is cut to a circular shape that generally conforms to the shape of the planter pot and is diametrically larger. The larger diameter of the plant coaster


20


in relation to the plant pot provides sufficient surface area for the absorption, evaporation and dispersion of any accumulated moisture emanating from the plant. When used as a grill mat, the mat is rectangular and may have rounded corners.




Referring to

FIGS. 3 and 4

, in use, the plant coaster


20


is positioned underneath, and generally concentric with, the item such as the potted plant


24


, or the gas grill


36


. The generally rectangular mat


38


under the gas grill protects the decking


40


. The invention is placed such that a significant portion of the non-woven fabric


21


is exposed to the atmosphere and the vinyl backing material


22


is in contact with the surface


25


to be protected.




Moisture, grease, food, or other matter from the item situated on the mat that ordinarily would stain and damage the surface


25


underneath the item, is suspended in the fibers of the non-woven fabric


21


. Normal evaporation will cause said fabric to dry. Vinyl backing material


22


protects the underlying surface


25


from moisture damage.




The fiber material provides an excellent cushioning effect to prevent damage to the surface upon which it is placed as well as providing a moisture absorption capability. The thickness of the coaster in a preferred embodiment is 0.110 to 0.125 inches thick including the vinyl backing. The layer of cured vinyl backing is suitably 0.005 to 0.010 inches thick. The thickness of both the fabric material and vinyl can, of course, be varied.




In one preferred embodiment, the fibers are 100% acrylic. Alternatively, polyester or natural fibers may also be utilized in certain fabric mixes.




The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.



Claims
  • 1. A method of manufacturing an absorbent impervious mat for protection of surfaces, the method comprising the steps of:a) combining a plurality of fibers in a layer; b) needle punching said layer to intertwine said fibers into a non-woven mesh; c) applying a flexible impervious to moisture layer of material to one side of the layer of fiber and leaving the other side with the fibers exposed; d) cutting the layer to a desired shape with a periphery; and e) applying stitching around the circular periphery of the layer of fiber.
