The example embodiments in general are directed to a cutlery dispensing system for dispensing cutlery and 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.
Disposable cutlery or utensils such as plastic or bio-degradable 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. The disposable cutlery may represent a less expensive alternative to reusable cutlery, for example, at eating facilities or social gatherings where it is undesirable or cost prohibitive to clean the cutlery for reuse. However, providing disposable cutlery may present a number of potential drawbacks related to the manner in which the cutlery is provided.
Certain eating facilities may provide disposable cutlery in loose form within open-air bins or similar containers in which all patrons place their hands to grasp and retrieve a fork, spoon, knife, or spork. Open-air bins are relatively unhygienic, however, and may facilitate transmission of bacteria and the like from one patron to the cutlery and ultimately to another patron.
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.
Accordingly, in addition to the issues noted above, other 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 provide an inventory control means in that it allots only one utensil per actuation.
A conventional sanitary cutlery dispenser is disclosed in U.S. Pat. No. 8,272,533, currently assigned to Waddington N. America of Massachusetts. The '533 patent describes an apparatus and a method of dispensing.
The escapement leaf spring 30 is mounted to an escapement spring axle 32 to allow the movement of escapement leaf spring 30 during the movement of the escapement actuator finger 26 from a rest position 25 (
Thus, the escapement mechanism 15 has two pivot points. The first pivot point is connected to the housing front wall and escapement mechanism 15. This is shown by the escapement spring axle 32 being connected to the escapement leaf spring 30, permitting the leaf spring 30 to move (together with an actuator 38 to expand spring tines 16, 34) based on pivoting movement of the leaf escapement finger 26). There is a second pivot point (at axle 36) that allows pivoting motion of finger 26 once a utensil 10 that is being removed contacts the finger 26.
Accordingly, removal of a utensil 10 from escapement mechanism 15 in the '533 patent causes contact with a bottom end of the finger 26, deflecting its bottom end laterally outward, forcing it to pivot inward via axle 36 (at its top) and also to cause movement of the leaf spring 30 and actuator 38 via its pivot axle 32. The actuator 38 then spreads the spring tines 16, 34 (expands), to permit a utensil 10 to drop and a next to last utensil 10′ and its stack to be held by the protrusion on spring tine 34 (upper tine).
Therefore, in the '533 patent there is a key functional requirement that the escapement actuator finger 26 undergoes multiple pivot rotations against spring pressure to cause a utensil 10 to drop. There is a need for a better solution to sanitary cutlery dispensing that what is shown and described in the '533 patent and elsewhere in the prior art. Namely, there is an industry need for an improved cutlery dispenser system that conforms to the highest standards of hygienic practices, while providing a secure dispensing system with an improved process of dispensing cutlery and utensils in a controlled fashion.
An example embodiment of the present invention is directed to a dispensing system for utensils and cutlery. The system includes a housing having a cutlery distribution area with at least one opening therein for exposing a handle end of a presenting utensil for removal by a user. The system additionally includes a stack assembly having at least one stack chamber configured to hold a vertical stack of utensils and aligned with the at least one opening. The system further includes a trigger assembly actuated by the user removing a single presenting utensil out of the at least one opening to release a single lowest utensil from the vertical stack, for presentation of its handle end extending out of the at least one opening at the cutlery presentation area for removal by a next user. A chute delivers each released single lowest utensil of the vertical stack to its at least one opening for removal by the next user.
Another example embodiment is directed to a utensil dispensing system. The system includes a housing, a lower part of which includes a plurality of spaced adjacent openings therein, each opening exposing a handle end of a presenting utensil for removal by a user. The system additionally includes a plurality of stack chambers in adjacent relation to one another, each configured to hold a vertical stack of utensils and aligned with a corresponding opening, and a trigger assembly actuated by the user removing a single presenting utensil out of one of the openings by its handle end to release a single lowest utensil from the vertical stack within the stack chamber associated with that opening, as a next presenting utensil for removal by a next user of the system. The system further includes a chute for delivering each released single lowest utensil to its corresponding opening for removal by the next user, the released single lowest utensil subject to rotation as it is released into the chute.
Another example embodiment is directed to a utensil dispensing system. The system includes a housing, a lower part of which includes a plurality of spaced adjacent openings therein, each opening exposing a handle end of a presenting utensil for removal by a user. The system additionally includes a plurality of stack chambers in adjacent relation to one another, each configured to hold a vertical stack of utensils and aligned with a corresponding opening, the top of each stack chamber and an interior passage extending downward within each chamber having a unique shape that respectively mimics the profile of one or more of a fork, spoon, spork, and knife. The system further includes a trigger assembly actuated by the user removing a single presenting utensil out of one of the openings by its handle end to release a single lowest utensil from the vertical stack within the stack chamber associated with that opening, as a next presenting utensil for removal by a next user of the system.
Example embodiments will become more fully understood from the detailed description given herein below and the accompanying drawings, wherein like elements are represented by like reference numerals, which are given by way of illustration only and thus are not limitative of the example embodiments herein.
In the following description, certain specific details are set forth in order to provide a thorough understanding of various example embodiments of the disclosure. However, one skilled in the art will understand that the disclosure may be practiced without these specific details. In other instances, well-known structures associated with manufacturing techniques have not been described in detail to avoid unnecessarily obscuring the descriptions of the example embodiments of the present disclosure.
Unless the context requires otherwise, throughout the specification and claims that follow, the word “comprise” and variations thereof, such as “comprises” and “comprising,” are to be construed in an open, inclusive sense, that is, as “including, but not limited to.”
Reference throughout this specification to “one example embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one example embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Further, the particular features, structures or characteristics may be combined in any suitable manner in one or more example embodiments.
As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. The term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise.
As used in the specification and appended claims, the terms “correspond,” “corresponds,” and “corresponding” are intended to describe a ratio of or a similarity between referenced objects. The use of “correspond” or one of its forms should not be construed to mean the exact shape or size. In the drawings, identical reference numbers identify similar elements or acts. The size and relative positions of elements in the drawings are not necessarily drawn to scale.
The example embodiments hereafter describe a dispensing system for dispensing cutlery and 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. As will be shown in more detail below, in the system a utensil handle is presented at a cutlery distribution area outside the housing for access by a user when the user approaches the system. Multiple stacks of utensils are provided in adjacent relation within designated stack chambers arranged inside a housing of the system.
The example system offers a much more sanitary dispensing process that does not require the user to touch a button or anything else to release the utensil. As a user pulls a handle and hence utensil out from the cutlery distribution area, that action triggers the next utensil directly above it to drop from the designated stack chamber and present in a similar way for the next user. Accordingly, the example system can generally be loaded with multiple stacks of utensils, and during loading, the operator does can load the utensil stacks without having to physically touch any utensil, maintaining the sanitary integrity of the cutlery in place. If the system becomes jammed, however, it may become necessary to touch one or more utensils or pieces, but these can be removed from the system by taking out one at a time in the ordinary fashion.
Particularly, the example system offers presentation of an end of a utensil, wherein the system employs two counter-sliding blades which allow a single utensil to drop, while constraining the utensil stack within a given stack chamber. Accordingly, the dispenser system requires no touch to distribute a new utensil except by pulling the previous utensil out of the housing by its handle. One benefit is improved sanitary conditions to prevent the spread of germs. The example system also provides significant customer convenience and promotes refilling of designated cutlery and utensil product designed for use in the system.
Referring now to
The stack assembly 110 includes outer side metal sheets 114, a front lower plate 115, and a rear metal plate 117 with support brace 118 that bound the stack chambers 111A-C. Plates 114, 115 and 117 are secured to inner surfaces of the various access panels 102, 104 via suitable fasteners, which in one example may include wood screws with lock washers 116A, as well as sheet metal screws 116B. The outer side metal sheets 114 could also be included into the structure of the stack assembly 110 inside of attached thereto.
The internal components within the housing 101 of system may be understood as comprising three primary part groups or assemblies: (a) the stack assembly 110, which includes one or more of the aforementioned chambers 111A-C, each of which may be configured to hold a given number of utensils 160 or pieces of cutlery, one example being a vertical stack of 50 in each chamber 111A-C for a total of 150 pieces; (b) a trigger assembly that is actuated by the user removing a single presenting utensil 160 from one or more openings 107 in the cutlery presentation area 105 to release a single utensil 160 piece at a time per opening 107, resetting the previously-removed utensil 160 with another lowest sitting utensil 160 of the vertical stack of utensils in a given chamber 111A-C in a ready position; and (c) a chute 140 for delivering each lowest sitting ready utensil 160 or piece of cutlery to the opening 107 for removal by a next user. In an example detailed further below, the chute 140 by its construction causes a dropping utensil to rotate 90 degrees from the position in which it was released from its lowest location in the vertical stack in the stack chamber, to where its handle exits opening 107 for presentation to the user.
In a loading operation, a person removes the front access panel 104 and then flips up the top access panel 103 (top access panel 103 is hinged at back to provide access from above). This gives access for the user to take a packaged load of 50 vertically-stacked utensils 160 (“refill cartridge 150”) and to feed it into its respective stack chamber 111A-C of the stack assembly 110 from the top. Referring to
For a reload operation, the user grasps wrapper 152 and lowers the refill cartridge 150 as far down into a chamber 111A-C as possible and then removes the binding wrapper 152 which holds the utensils 160 together in the refill cartridge 150. In general, the binding wrapper may include a pull tab or perforations along the wrapper 152 and/or flanges 154 that facilitate removal. Additionally, a front scooped-out portion or channel 112 is provided down the length of each stack chamber 111A-C. This provides hand access of an operator's hands for more easily clearing jams in the vertical columns of utensils 160.
The top of each stack chamber 111A-C and the interior down within each chamber 111A-C has a unique shape (see openings 113A-113C) that mimic the profile of any of a fork, spoon, spork, and/or knife, as best seen in
With reference now to
With continued reference to
Once the upper chisel 122 is in place to act as a shelf for the on-deck utensil 162, the lower chisel 123 retracts laterally away from the handle end to allow the ready utensil 161 to drop into the chute 140 (also there is an additional ledge (not shown) within chute 140 that acts as a trigger for rotating the ready utensil 161 (as it is released from its vertical stack of utensils) by 90 degrees as it travels through the chute 140), so as to become the next presenting utensil 160 with its handle end exposed through opening 107 for removal by a next user, with the on-deck utensil 162 now becoming the ready utensil 161, etc. The handle end of the ready utensil 161 drops first, because of the fixed shelf 121 supporting the other end (eating end) of the ready utensil 161.
Referring to
A proximal end of the actuator arm 130 nearest the rear metal plate 117 includes a lever brace 131 for support and is connected between an interior separator plate 119 (which separates stack chamber 111A from 111B and stack chamber 111B from 111C) and the outer side metal sheet 114 via an axel rod 133 which extends through all central openings of fixed axle bushings 134, pairs of each bounding the actuator arm 130 proximal end there between, each axle bushing 134 securable in one of sheets 114 and 119. A junction where each edge of the proximal end of actuator arm 130 meets a portion of axle rod 133 and meets an axle bushing 134 forms a pivot moment 132. The actuator arm 130 is able to pivot at pivot moment 132 about the axle rod 133 as the axles 138 shift in the defined areas 139 formed in the cam body 125, which occurs upon a user actuating force imparted by the user pulling a presenting utensil 160 out of opening 107 in the facing plate 106 at the cutlery presentation area 105.
Upon release, spring force from spring 137 causes the elements of the trigger assembly to return to the starting position, while reloading a new handle end of a presenting utensil 160 in each opening 107 via chute 140. The spring 137 is connected between a given stack chamber 111A-C and a surface of the actuator arm 130. The upper end of the spring 137 pushes along the bottom surface of the stack chamber 111A. In particular, and as best shown in
Because the trigger assembly is spring loaded, the two chisels 122, 123 return to the starting point once the actuating force from a user pulling out a utensil 160 is released. This has the effect of moving the lower chisel 123 out toward the handle end of a utensil 160 into the shelf position, and returning the upper chisel 122 back to its original (or retracted state) position. When this happens, the handle end of the on-deck utensil 162 drops onto the lower chisel 123 (see
When a utensil 160/161/162 . . . 16N (represented hereafter for simplicity as simply “utensil 160”) drops into the chute 140, it slides down a diagonal slide (see
The functional eating end of the utensil 160 is retained within housing 101 by a movable barrier element 136. Referring now to
The barrier element 136 moving upwards is the activation mechanism by which the trigger assembly operates as previously described. Namely, a button 135 is connected to (or integral with) the bottom of the barrier element 136. When a load of utensils 160 is initially placed into a given stack chamber 111A-C of the stack assembly 110, the operator needs to push the barrier element 136 upward in order to drop the first lowest seated utensil 160 at the bottom of the refill cartridge 150 into the chute 140.
Referring now to
The top access panel 103 is hinged such that it can remain open in any position. When it is in the down position, closed, it holds the top edge of the front access panel 104 in place. The top edge of the front access panel 104 may be held in place by another mechanism as well, such as a magnet or latch. The bottom edge of the front access panel 104 is keyed into a trough or slot (not shown) such that it will not come forward when placed in the slot that is located between the front lower plate 115 and the facing panel 106. The bottom of the front access panel 104 is notched to fit into this slot. So, to reinstall the front access panel 104 (such as after a loading operation), an operator places the bottom edge into this slot, pivots the panel 104 rearward to a vertical position, then secures its top edge by bringing down top access panel 103 to the closed position which holds the top of the front access panel 104 in place.
