Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Provisional Application No. 61/585,404, filed Jan. 11, 2012.

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to an apparatus for use in a refrigerator to protect the surfaces of the refrigerator from stains resulting from leakage and condensation. One embodiment of the invention comprises a refrigerator liner that is perforated along such that the size of the coaster can be easily adjusted to conform to varying sizes of refrigerator shelves and/or compartments.

Containers holding food and beverages stored in a refrigerator often leak or spill causing stains on the surfaces of the refrigerator that can be difficult to clean. In addition, food items, such as fruits, vegetables and meats, are often stored in refrigerator compartments and forgotten by the owner for long periods of time. The resulting spoilage of the long forgotten food typically results in the production of malodorous liquid leaking and staining the refrigerator surface. Condensation forming on food and beverage containers can also produce unwanted liquid on the refrigerator surfaces.

Accordingly, there is a need for an apparatus to protect the surfaces of a refrigerator from such spills and leaks to minimize the work necessary to keep the refrigerator clean.

SUMMARY OF THE INVENTION

Therefore, one object of the present invention is to provide an apparatus that acts as protective barrier between food and beverage items and the surface of the refrigerator on which the items are placed. Another object of the invention is to provide a refrigerator liner, in which the user can easily adjust the size and shape to conform to varying sizes of refrigerator shelves and compartments. These and other objects of the invention can be obtained in the preferred embodiments of the invention described below.

One embodiment of the invention comprises a coaster apparatus for positioning on a surface of a refrigerator and providing a moisture barrier thereon. The coaster comprises a first substantially straight side edge, a second substantially straight side edge extending substantially parallel to the first straight side edge having a length shorter than the first side edge, and first and second opposed contoured side edges connecting the first and second straight side edges.

According to another embodiment of the invention, the coaster is comprised of a liquid absorbent material.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION AND BEST MODE

A refrigerator coaster according to a preferred embodiment of the invention is illustrated in FIG. 1, and shown generally at reference numeral 10. As used throughout this application, “refrigerator” refers generally to any cooling apparatus that can include refrigeration and/or freezer sections. As such, the coaster 10 can be used in both refrigeration and freezer sections of a conventional refrigerator.

As shown in FIG. 1, the coaster 10 comprises an elongate panel having a first straight side edge 12, a relatively shorter straight side edge 14, and two contoured side edges 16, 18 joining the two straight side edges 12, 14. Preferably, the contoured side edges 12, 14 have a convex curvature, as shown in FIGS. 1 and 2. The coaster 10 can be made of a cellulose/starch paper board, or other suitable material. The coaster 10 has a top surface shown in FIGS. 1 and 3, and a bottom surface shown in FIG. 5. The top surface of the coaster 10 can have a decorative design, such as the pattern of dots shown in FIG. 1.

As shown in FIGS. 1 and 2, the coaster 10 can be perforated along lines 20, 22 and 24. As such, the size of the coaster 10 can be easily reduced to fit into a smaller desired area by tearing at one or more of the perforated lines 20, 22, 24 and removing portions of the coaster. Preferably, the coaster 10 also includes score lines 32, 34, beginning at opposite ends of the first straight side 12, approximately one-half inch inward from the perforated lines 22, 24, respectively, and extending for approximately three inches until they terminate at the perforated lines, 22, 24, respectively, as shown in FIG. 2.

Preferably, the first straight side 12 has a length of approximately 13⅝ inches, and the second straight side 14 has a length of about 7½ inches. Preferably, the distance from the first straight side 12 to the shorter straight side 14 is about 6 5/16 inches. Additional preferred dimensions of the coaster 10 are shown in FIG. 2. These preferred dimensions make the coaster particularly suitable for positioning in the interior door shelves of most conventional refrigerators.

The coaster 10 is preferably made using a laser cutting technique, which minimizes cracking along the outer edges 12, 14, 16, 18 and perforation lines 20, 22, 24. Laser cutting allows for manufacturing the coaster 10 in up to two thousand different sizes, thereby eliminating the need to create a die, such as is used in steel rule die manufacturing processes, for each different size. Laser cutting also allows for customized sizing to particular refrigerator models. For example, potential customers can go to an Internet website and select a particular coaster sized to fit their particular refrigerator model by entering the make and model of their refrigerator on the website. This information can then be entered into a computer database having linked to the laser cutter, which contains the specifications corresponding to the selected model enabling the laser cutter to cut the correct size and shape.

A method of using the coaster 10 according to a preferred embodiment of the invention is illustrated in FIGS. 3 and 4. The coaster 10 can be positioned on the bottom of a refrigerator shelf 50, as shown in FIG. 3. As shown in FIG. 4, various food and beverage containers 60 can be positioned on the coaster 10. As such, any leakage and/or spillage from the food containers 60 is received on the coaster 10, and does not directly contact the refrigerator shelf 50.

Another method of using the coaster 10 according to a preferred embodiment of the invention is illustrated in FIG. 5. The coaster 10 can be part of a promotional piece 70 that comes with a new refrigerator. The promotional piece 70 can be positioned within the refrigerator's water/ice dispenser section 80, as shown in FIG. 5. The coaster 10 can be attached to the promotional piece 70 along a perforated line, and the user can remove the coaster 10 by tearing along the perforated line.

Another preferred embodiment of the invention is illustrated in FIG. 6, and shown generally at reference numeral 100. A sheet 100 contains a plurality of refrigerator coasters 110. Preferably, the sheet 100 has a length of 44¾ inches and a width of 30¼ inches. The sheet 100 contains ten substantially rectangular coasters 110. Preferably, each coaster 110 has a length of about 14 inches and a width of about 8½ inches. The coasters 110 are attached to the sheet 100 along perforated lines 120, and each coaster 110 has three substantially parallel perforated lines 122, 124, 126 extending across the width of the coaster 110. Additional preferred dimensions of the sheet 100, including positioning of the perforated lines 122, 124, 126 within each coaster 110, are provided in FIG. 6.

Each coaster 110 can be removed from the sheet 100 by tearing along the coaster's respective perforated line 120. The size of each coaster 110 can be adjusted by tearing along perforated lines 122, 124, 126 as desired to conform to the size of various surface areas within a refrigerator.

Another preferred embodiment of the invention is illustrated in FIG. 7, and shown generally at reference numeral 200. A sheet 200 contains a plurality of refrigerator coasters 210. Preferably, the sheet 200 has a length of 44¾ inches and a width of 30¼ inches. The sheet 200 contains six substantially rectangular coasters 210. Preferably, each coaster 210 has a length of about 14 inches and a width of about 13 inches. The coasters 110 are attached to the sheet 100 along perforated lines 220, and each coaster 210 has a first perforated line 222 extending lengthwise on the coaster 210, and a second perforated line 224 extending across the width of the coaster 210, in substantially perpendicular orientation to the first perforated line 222. Additional preferred dimensions of the sheet 100, including positioning of the perforated lines 222, 224 on each coaster 210, are provided in FIG. 7.
