## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to U.S. Provisional Patent Application No. 62/062,667, filed Oct. 10, 2014, which is incorporated herein by reference in its entirety.


BACKGROUND
Preventing cross-contamination of food surfaces (such as utensils) and microbial growth on poorly cleaned or soiled surfaces is important to ensure the safety of the public. Cross-contamination can occur not just when a utensil comes into contact with multiple food sources, but can also occur when the utensil touches a common allergen, such as nuts. Additionally, microorganism growth can occur when utensils are improperly cleaned, or are not cleaned in a timely manner which may cause adverse effects to the public.
It is known that microorganisms may grow on food that is left out at room temperature for more than four hours, and in particular, prime microorganisms growth occurs between 40° F. and 140° F. Food surfaces coming into contact with food that has not been prepared or refrigerated properly can cause contamination, causing harmful effects if ingested. Maintaining clean and sanitized surfaces that come into contact with food, such as knives and other utensils, is thus an integral part of the food service industry.

WRITTEN DESCRIPTION
All states have food services codes and regulations that prescribe acceptable methods and times for cleaning utensils such as kitchenware (e.g., knives, spoons, etc.), equipment, tools, etc. However, maintaining this appropriate level of cleanliness also relies on the common sense of those persons responsible for ensuring that the codes and regulations are being complied with. For example, it is well known that debris that has not been removed from a soiled utensil may prevent proper sanitation of the utensil. Thus, it is imperative that the debris be removed prior to the sanitation process. Additionally, depending on the foodstuffs that the utensil is used with, the utensil may need to be cleansed very frequently. Thus, sanitation processes can often be laborious and time intensive, which is especially inconvenient during high service periods, such as lunch and dinner. Occasionally, and often in an effort to provide fast and reliable service for the customer, steps for cleaning utensils are forgotten about or skipped. Accordingly, it would be desirable to have a simplified system that may be used to better ensure proper cleaning and sanitization of utensils.
Systems and methods for providing sanitized utensils are provided herein. Referring to FIG. 1, in one embodiment, a system 10 generally includes a shelf (generally, 100), a container 150 for holding a cleaning solution, and a removable insert 200.
The shelf 100 may take various embodiments, and FIGS. 1, 2, and 5-7 illustrate various exemplary embodiments of shelves 100. As shown in FIG. 1, the shelf 100a may have horizontal and vertical supporting walls 110 and may include an attachment 120 which may be removably secured to the shelf 100a via a mechanical fastener such as a bolt and wing nut construction 121, as shown in FIGS. 1 and 2, inserted through attachment points 123 and 125 located on the attachment 120 and shelf 100a, respectively. The mechanical fastener 121 may allow the attachment 120 to rotate between a closed position and an open position (see FIG. 2). The attachment 120 may have a void 122 for receiving the container 150 (and thus the removable insert 200 as described herein). Optionally, the attachment 120 may additionally have a void 124 for receiving, for example, a drying basket 250. Other voids may also be provided.
Alternately, as shown in FIGS. 5-7, the shelf 100b, 100c, 100d may include a receiving rack 105 which may have a void 122 for receiving the container 150 and optionally additional voids, such as void 124 for receiving the drying basket. Still additional voids 126 may also be provided to hold various other structures (e.g., as shown in FIG. 6). Walls 110 may provide support for the receiving rack 105.
The shelf 100 may be configured to attach to, or otherwise interact with, an existing countertop. Accordingly, the shelf 100 may have various brackets and/or supports for securing the shelf 100 to the counter. In FIGS. 1, 5, and 6, the shelf 100 may attach to the counter via mounting brackets 112 and/or clips 114. The brackets 112 and/or clips 114 may be secured to the counter with mechanical fasteners (e.g., screw, nail, rivet, nut and bolt, etc.) to maintain the shelf 100 in position at the counter. FIG. 7 illustrates an example of a shelf 100 that is designed to sit atop the counter. Base portions 116 engage with the top of the counter, and mechanical fasteners may be inserted through apertures 118 formed therein to secure the shelf 100 to the counter.
In some embodiments, the shelf 100 may be positioned where users of the system 10 may accidentally come into contact with edges of the shelf 100. Accordingly, the edges of the shelf 100 may be covered with, for example, a rubber or plastic bumper to minimize possible injuries as a result of coming into contact with the shelf.
The container 150 has a containment area 152 extending downwardly from an upper periphery 154. The perimeter of the upper periphery 154 may be slightly larger than the perimeter of the containment area 152 to form an edge 153. A lip 156 may be provided around the edge of the upper periphery 154 of the containment area 152. The perimeter of the lip 156 may be slightly larger than the perimeter of the void 122 in the attachment 120 such that the container 150 is maintained in the void 122. In embodiments, the container 150 may be, for example, a 1⁄6 size, 6′′ deep food pan (e.g., Cambro® pan). It shall be noted that other sized (and shaped) pans may additionally, or alternately, be used.
The container 150 is configured to hold an antimicrobial agent. There are many antimicrobial agents which may be acceptable with the system 10, including but not limited to oxidizing agents, phenolics, thymol-based disinfectants, alcohols, et cetera. Due to the potentially corrosive nature of particular antimicrobial agents that may be used, it may be preferable for the container 150 to be constructed of a material that is resistant to such corrosion. Exemplary materials include but are not limited to aluminum, stainless steel, ceramic, et cetera.
Referring now to FIGS. 3 and 4, the insert 200 may have sidewalls 202a, 202b, 202c, and 202d which are substantially vertical to allow the insert 200 to fit inside the upper periphery 154 of the container 150, for example, resting atop the edge 153. Accordingly, the perimeter of the insert 200 may generally correspond to the perimeter of the upper periphery 154. The insert 200 may be constructed of molded plastic, for example.
One or more receptacles 207a, 207b, 207c (generally, 207) may be formed along a top rim 204 of the insert 200 and configured to retain a respective scraping member 212a, 212b, 212c (generally, 212). The scraping members 212 may be additionally secured in the respective receptacles 207 via an adhesive, although it may be understood that the scraping member 212 may need to be removed and replaced occasionally. Accordingly, temporary attachment of the scraping member 212 may be preferable.
The scraping member 212 may be any device capable of removing debris and/or liquid from a utensil. For example, acceptable scraping members include squeegees, sponges, scouring pads, brushes, or similar instruments. One of ordinary skill in the art may also recognize that it may be beneficial to incorporate a variety of scraping members, such as a squeegee and a sponge. In one embodiment, the insert 200 has at least two squeegees 212, one for removing debris and a second to exsiccate liquid after the utensil is removed from the sanitizing solution. In another embodiment, illustrated in FIG. 4, a plurality of rubber membranes or squeegees 212d may extend outwardly from supports 214. As is described in greater detail below, the rubber membranes 212d may dry off utensils as they are removed from the sanitizer solution.
As mentioned above, it is imperative that contaminated utensils do not come into contact with food for human consumption. Accordingly, it is important that utensils that have been sanitized are not again accidentally contaminated. Accordingly, the squeegees 212 (or other scraping member) may be distinguished from each other by different colors or sizes, for example. Hence, the person cleaning the utensil can easily recognize a squeegee that is for debris removal versus a squeegee that is meant to remove excess sanitizer solution, thus avoiding accidental contamination of the utensil which would require a second (or more) immersion into the sanitizer solution.
A partition 208 may extend between two opposing side walls (e.g., 202b and 202d) to form a debris channel 209. As described in greater detail below, the channel 209 may catch debris from utensils to prevent the container 150 from becoming congested with unwanted debris. Accordingly, a floor may be provided under the channel 209.
Opposing ends of at least one cleaning rod 210 may be mounted along opposing inside faces (e.g., 206b and 206d) of the insert sidewalls 202b and 202d for cleaning utensils such that the rod 210 is parallel with the partition 208. Alternately, the rod 210 may extend from an inside face 206a of the partition 208 to an inside face of the opposing side wall 206c. Apertures in the opposing inside faces 206b and 206d may receive respective ends of the cleaning rod 210 to hold the rod 210 in place. The cleaning rod 210 may be removable from the inside faces 206b and 206d such that the rod 210 may be exchanged as needed. Alternately, respective ends of the rod 210 may be adhered inside the apertures in the opposing side faces 206b and 206d. 
It may be recognized that multiple cleaning rods 210 may preferably be incorporated into the insert 200 to more effectively clean utensils. Moreover, it shall be recognized that the cleaning rods 210 may be provided in other alternative configurations. For example, the rods 210 may be provided around the perimeter of the insert 200, rather than extending between opposing side walls 202b and 202d or 202a and 202c. 
In a preferable embodiment, the cleaning rods 210 may be, for example, twisted-wire brushes having bristles made of a polymer (such as nylon) or other appropriate material. Other types of cleaning tools may additionally, or alternately, be incorporated into the insert 200. For example, in some embodiments, the cleaning rods 210 may be equipped with sponges, scouring pads, et cetera.
The diameter of the bristles on each of the brushes 210 may be the same (e.g., 3/16′′) or varied (e.g., 3/16′′, 5⁄8′′, and 13⁄8′′, et cetera) based on the needs of the particular application. For instance, brushes with smaller bristle diameters may be better equipped to remove debris that is caked on a utensil, while brushes with larger bristle diameters may be useful for cleaning less-soiled utensils. Regardless of the size of the bristles, it may be beneficial for the bristles of the brushes 210 to overlap such that more than one side of a utensil may be cleaned at a time.
As noted above, the drying basket 250 may be configured to fit into the corresponding aperture 124 in the attachment 120. The basket 250 may be further configured such that cleaned and sanitized utensils can be safely stored therein. For example, it will be understood by those of skill in the art that the basket 250 is sufficiently designed such that the length can adequately hold sharp utensils (e.g., knives) of all sizes without a risk of the utensils prematurely falling out of the basket. The drying basket 250 may have a plurality of apertures 252 formed therein so as to allow air to pass through the basket 250 and dry the stored utensils stored therein.
It may be preferable for the basket 250 to be formed from a material that is resistant to sharp edges (such as those from a knife) and water damage, such as aluminum or stainless steel. It may additionally be desirable for the basket 250 to be formed of a material that may help prevent the utensils from slipping in the basket 250, such as rubber. Alternately, the basket 250 may be formed from a material such as stainless steel or aluminum and coated with rubber or similar material.
In use, a user of the system may take a soiled utensil and rub the utensil along one of the scraping members 212, such as scraping member 212a shown in FIG. 3. The debris from the utensil may fall into the debris basket 209. The user may then insert the utensil through the top of the insert 200 such that the utensil comes into contact with at least one of the cleaning rods 210 and into the container 150 which holds a cleaning solution. As the utensil is inserted further into the container 150, the utensil comes into contact with the cleaning solution. The user may then remove the utensil from the container 150 and the insert 200. This process may be completed until the utensil is cleaned and sanitized.
Once the utensil is cleaned and sanitized, excess liquid may be removed from the utensil by scraping the utensil against another squeegee 212, such as 212b or 212c. The excess liquid may run back into the container 150. The utensil may then be placed in the drying basket 250 to complete the drying process. Alternately, the utensil may immediately be used.
Many different arrangements of the various components depicted, as well as components not shown, are possible without departing from the spirit and scope of the present invention. Embodiments of the present invention have been described with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the aforementioned improvements without departing from the scope of the present invention. Further, it will be understood that certain features and subcombinations are of utility and may be employed within the scope of the disclosure. Further various steps set forth herein may be carried out in orders that differ from those set forth herein without departing from the scope of the present methods. This description shall not be restricted to the above embodiments.
