The invention pertains to a system and method of dispensing recyclable cutlery utensils and, more particularly, to a system and method that dispenses these utensils hygienically without users having to physically touch any part of a dispenser, other than the specific utensil they wish to dispense for their use.
A convergence of factors, such as reduced antibiotic effectiveness coupled with an increasingly fast food directed environment, have combined to create a need for a new cutlery dispenser. The dispenser should have both the ability to dispense cutlery in a hygienic manner and also provides an inventory control means in that it allots only one utensil per actuation.
Disposable cutlery such plastic spoons, forks, knives, and Sporks® are normally used in casual restaurant settings and are provided by the eating establishment for use in the restaurant and with take-out food. To ensure that this cutlery is provided in a hygienic form, a purveyor often purchases bulk quantities of individual portions of cutlery each pre-sealed in a small bag. The bag may also contain a napkin, dry condiments, and a hand sanitizer wipe. Such bags are generally more expensive than the sum of individual utensils due to the processing and materials necessary to form the bags. Also, these bags may provide more items than the user requires, which is uneconomical.
An option to such prepackaged bags is the presentation of cutlery in a tray or cup positioned near the point of sale. This approach allows the customer to select only the utensils desired. However, this form of supply can be unsanitary and unhygienic if a customer does not take a utensil that is purposely touched or inadvertently brushed against while rummaging through the proffered selection to find the perfect spoon for soup, for example. Airborne pathogens may settle on exposed surfaces of the remaining cutlery. The unregulated dispensing of the cutlery also permits the customer to take more utensils than needed, thus resulting in a lower profit margin for the establishment.
It is an object of the present invention to provide a reliable, efficient system for fulfilling recyclable cutlery needs.
It is a further object of the present invention to provide a non-electric automatic cutlery fulfillment system that requires no power budget overhead and requires little involvement or oversight by the eating establishment.
It is another object of the present invention to broaden the scope of hygienic practices and ultimately provide a secure cutlery dispensing fulfillment system.
It is still another object of the present invention to provide a time limited inventory containment process to minimize undo cutlery dispensing for personal gain.
It is a further object of the invention to provide an improved method for dispensing cutlery in a controlled fashion.
It is further still another object of the present invention to provide stackable magazine sections to enlarge the capacity of the dispenser.

Referring now to
The following is the sequence for dispensing a no touch spoon or fork utensil. The top 20 hinges open for filling the dispenser 100 with utensils 10. An operator loads the utensil bulk refill pack 200 while wearing rubber gloves, which is a normal item in the food industry. The utensils 10 are aligned by guides 12 along the Y-axis and the utensil container box 72 on the ends in the X-axis. The stack 76 of utensils 10 rests on two stops 14 and 16. Distal stop 14 is a ledge that is part of the back wall of dispenser 100 and the complementary side is the escapement release protrusion 16. Tab 74 of bulk refill pack 200 is pulled upwards on the utensil bulk refill pack 200. A pressure sensitive adhesive (PSA) tape 73 is peeled back on one side of the cardboard magazine container 72. After the tape 73 is peeled across the bottom of stack 76, the whole utensil stack 76 is released and the entire cardboard utensil container box 72 and tape 73 is removed vertically. A single utensil 10 is manually loaded into the exit area rest position 19. At this point, the dispenser 100 is ready for use.
The consumer then pulls on handle 11 of the utensil 10 in the exit area rest position 19. The escapement finger 26 rotates 25, 25′ about a pivot pin 36. Two escapement finger corners 40, 42 push against the escapement leaf spring 30. The escapement spring hold protrusion 34 engages the bottom handle surface of the next to last utensil 10′ to hold all but the last utensil in place. As the escapement finger corners 40, 42 continue to rotate, the escapement release protrusion 16 moves and releases only the bottom utensil handle 10″. The bottom utensil handle 10″ falls. The captured distal end 14 rotates, then releases 17 from the ledge 14. The handle 10″ of the falling bottom utensil drops into a groove 27 in the bottom slide guide 29 and slides downward until the spoon or fork underside stops on escapement finger 26. Two flexible wires 24 act as guides for the handle if the consumer pulls the exiting utensil 10″ too slowly.
