Abstract

A single-serve, sanitary, gravity-feed cutlery dispensing system without moving parts that holds 4-to-5 times the cutlery in prior art dispensers. Its base unit holds multiple refillable dispensing modules each having a valley at the bottom of a vertically-extending storage channel with a length dimension shorter than the cutlery housed therein, thus stored utensils have angled stacking while moving downwardly toward the valley. When one end of the bottommost utensil engages the valley, it becomes locked into a horizontally-extending dispensing position with opposing end user accessible. The utensil in the dispensing position blocks removal of stacked utensils remaining in the channel. Only withdrawal of the bottommost utensil causes a next utensil to drop down into the locked dispensing position. This arrangement also prevents reinsertion of dispensed utensils. Cutlery of any design is usable with the dispensing system, and dispensing occurs equally well with the handle or opposite end engaging the valley.

Claims

1. A cutlery dispensing system without moving mechanical parts for single-serve and sanitary dispensing of cutlery units each having a first end and an opposed second end, said system comprising:

at least one module having a vertically-extending channel formed therein generally in a shape of the cutlery units to be dispensed therefrom, said channel slightly wider than the cutlery units intended for dispensing, said channel also having a back channel portion holding the first ends of the cutlery units that remain out-of-view and in a sanitary condition until dispensed and a front channel portion holding the second ends of the cutlery units that eventually become exposed for dispensing, said channel also having a shorter length dimension than that of the cutlery units to be dispensed, the cutlery units positioned within said channel in an inclined non-horizontally extending orientation allowing the first ends of stacked cutlery units in said channel to be located at a lower elevation than the second ends thereof that eventually become exposed for dispensing, said at least one module further having a locking valley positioned below said back channel portion, a dispensing opening positioned below said front channel portion, and a void relief area communicating with said dispensing opening and said front channel portion, wherein a positioning event occurs for a bottommost cutlery unit in said channel via gravity alone and without assistance of any moving mechanical parts as a result of a user withdrawing the exposed second end of a cutlery unit extending through said dispensing opening in a dispensing event, and as dispensing of the cutlery unit with its exposed second end extending through said dispensing opening occurs said void relief area allows the bottommost cutlery unit still in said channel to drop in a downwardly direction until its first end leaves said back channel portion and engages said locking valley while said first end concurrently remains in contact with a new cutlery unit now having bottommost positioning in said channel, which then directly causes the opposing second end of a downwardly-dropped cutlery unit to rotate downwardly via gravity into a substantially horizontally-extending and exposed dispensing position for a next dispensing event.

2. The system of claim 1 further comprising a housing configured for supporting said at least one module, said housing and said at least one module each having anchoring features with a configuration complementary to one another that securely maintains said at least one module within said housing during cutlery dispensing.

3. The system of claim 2 wherein said anchoring features comprise at least one hook and at least one hook rail.

4. The system of claim 2 wherein said housing further comprises a lid movable between an opening position permitting removal of said at least one module and a closed position that prevents removal of said at least one module.

5. The system of claim 1 wherein said at least one module has a two-part construction.

6. The system of claim 5 wherein said at least one module further comprises at least one alignment post and at least one complementary alignment socket.

7. The system of claim 1 wherein said at least one module further comprises strength-enhancing external ribbing.

8. The system of claim 1 wherein said at least one module further comprises at least one utensil indicator.

9. The system of claim 1 wherein said channel is replaced by friction-reducing guides alternating with relief areas together formed generally into the shape of the cutlery units to be dispensed therefrom.

15. A method for one-at-a-time dispensing cutlery units, said method comprising the steps of:

providing at least one of said modules in claim 1, a plurality of cutlery units intended for dispensing via said at least one module, each said cutlery unit having opposing ends, and a housing configured for supporting said at least one module with said housing and said at least one module each having anchoring features with a configuration complementary to one another that securely maintains said at least one module in a fixed position within said housing during dispensing of said cutlery units;

creating upright positioning for said vertically-extending channel of said at least one module sufficient to cause one of said ends of the bottommost one of said cutlery units later inserted into said vertically-extending channel to rotate downwardly into a horizontally-extending and exposed dispensing position for a next dispensing event;

loading at least two of said cutlery units into said vertically-extending channel of said at least one module allowing the bottommost one of said cutlery units in said channel to drop in a downwardly direction until the one of its opposing ends formerly in said back channel portion of said at least one module engages said locking valley, which then allows the other one of said opposing ends of said bottommost cutlery unit that was formerly in said front channel portion of said at least one module to rotate downwardly via gravity into a horizontally-extending and exposed dispensing position for a next dispensing event;

anchoring and maintaining said at least one module within said housing immobile during dispensing of said cutlery; and

a user withdrawing said exposed end of a cutlery unit extending through said dispensing opening which automatically without any additional action by the user allows the bottommost cutlery unit still in said channel to drop in a downwardly direction until the one of its ends formerly in said back channel portion engages said locking valley, which then allows the opposing one of ends said bottommost cutlery unit that was formerly in said front channel portion to rotate downwardly into a horizontally-extending and exposed dispensing position for a next dispensing event.

16. The method of claim 15 wherein said channel has a top cutlery-loading opening and a side with a vertically-extending slot communicating with said top opening, and further comprising the steps of providing said cutlery units in stacked array and bound with wrapping tape with adjacent ones of said cutlery units having like orientation, inserting said cutlery units in said stacked array and bound by said wrapping tape together through said top opening and into said channel, and withdrawing said wrapping tape from said channel through said vertically-extending slot.

17. The method of claim 15 wherein said at least one module has a two-part construction with separable parts, wherein said steps of creating and loading are reversed, and further comprising a step of separating said parts of said at least one module that occurs before said step of loading, and a step of joining said parts of said at least one module that occurs before said step of creating.

18. The method of claim 15 wherein said channel is replaced by friction-reducing guides alternating with relief areas together formed generally into the shape of the cutlery units to be dispensed therefrom.

19. A base unit usable as a part of the system in claim 1, wherein said base unit comprises a configuration for supporting said at least one module, said housing and said at least one module each having anchoring features with a configuration complementary to one another that securely maintains said at least one module in a fixed position within said housing during cutlery dispensing.

20. The base unit of claim 19 further comprising a protective lid over said vertically-extending channel of said at least one module, said lid movable between an opening position permitting removal of said at least one module and a closed position preventing removal of said at least one module.

10. A cutlery dispensing system without moving mechanical parts for single-serve and sanitary dispensing of cutlery units each having a first end and an opposed second end, said system comprising:

at least one module having at least a two-part construction, a narrow width dimension, at least one alignment post and an alignment socket complementary thereto, and strength-enhancing external ribbing, said module also having a vertically-extending channel formed therein generally in a shape of the cutlery units to be dispensed therefrom, said channel slightly wider than the cutlery units intended for dispensing, said channel also having a back channel portion holding the first ends of the cutlery units that remain out-of-view and in a sanitary condition until dispensed and a front channel portion holding the second ends of cutlery units that eventually become exposed for dispensing, said channel also having a shorter length dimension than that of the cutlery units to be dispensed, the cutlery units positioned within said channel in an inclined non-horizontally extending orientation allowing the first ends of stacked cutlery units in said channel to be located at a lower elevation than the second ends thereof that eventually become exposed for dispensing,

said at least one module further having a locking valley positioned below said back channel portion, a dispensing opening positioned below said front channel portion, and a void relief area communicating with said dispensing opening and said front channel portion, wherein a positioning event occurs for a bottommost cutlery unit in said channel via gravity alone and without assistance of any moving mechanical parts as a result of a user withdrawing a exposed second end of a cutlery unit extending through said dispensing opening in a dispensing event, and as dispensing of the cutlery unit with its exposed second end extending through said dispensing opening occurs said void relief area allows the bottommost cutlery unit still in said channel to drop in a downwardly direction until its first end leaves said back channel portion and engages said locking valley while said first end concurrently remains in contact with a new cutlery unit now having bottommost positioning in said channel, which then directly causes the opposing second end of a downwardly-dropped cutlery unit to rotate downwardly via gravity into a substantially horizontally-extending and exposed dispensing position for a next dispensing event.

11. The system of claim 10 wherein said channel is replaced by friction-reducing guides alternating with relief areas together formed generally into the shape of the cutlery units to be dispensed therefrom.

12. The system of claim 10 further comprising a housing configured for supporting said at least one module, said outer housing and said at least one module each having anchoring features with a configuration complementary to one another that securely maintains said at least one module within said housing during cutlery dispensing.
