The present invention relates generally to a bulk inventory dispensing apparatus and, more particularly, to a gravity-fed dispensing apparatus with a locking dispensing actuator. The apparatus allows bulk inventory stored in a dispensing bin to flow under the force of gravity upon release of a dispensing actuator locking portion of the bin thereby enabling rotation of the dispensing actuator. Once released, the dispensing actuator can then be articulated to permit stored inventory to be dispensed through an outlet portion of the bin into a staged receptacle.
Gravity fed bins for dispensing bulk inventory are used to dispense a wide variety of materials having a range of sizes and aggregate make-ups as diverse as hardware components, e.g., nuts and bolts, to retail grocery food, e.g., pastas, cereals, nuts, coffee (either beans or ground), dried soup mixes, candies, spices, and the like. Generally, such a bin is comprised of a hopper-type enclosure having an inlet at an upper end utilized to fill the enclosure with bulk inventory, an outlet or chute at its lower end utilized to dispense the material, and a flow control device located intermediate the upper and lower openings and controlled by a manually-actuated gate mechanism. This arrangement, in turn, permits manipulation of the amount of inventory being dispensed during the interval the handle or other control device is actuated. In operation, as the inventory is being dispensed, the force of gravity causes the portion stored above in the cavity to progressively migrate towards the lower end to replace the void left as portions of the inventory are dispensed. These types of bins generally include a downwardly angled or curving inner floor surface wall within the cavity that forms a slide to channel the stored inventory into a receptacle adjacent the outlet gate. Examples of prior art gravity fed bins can be found in the above-mentioned U.S. patents to Elmore, U.S. Pat. No. 4,903,866 to Loew, NewLeaf Designs' Vita-Bin® gravity bin product, and BestBins Corporation's gravity bins product.
Heretofore, the one means for dispensing such stored bulk inventory was to employ a bulk food dispenser generally known as a “scoop bin.” As the name suggests, a scoop bin typically comprises a plastic bin, often having a hinged lid that is lifted to provide the consumer access to the stored contents. A hand scoop is then employed to gather the bulk product for placement into a container. While scoop bins are effective for dispensing a wider variety of product than a gravity type dispenser, they suffer from several major disadvantages, particularly in the area of hygiene, because of the contamination that can take place in these types of dispensers. Sources of contamination include germs that may be attached to the scoop or scoop handle being transferred to the stored product during dispensing or from external debris falling into the bin cavity when the bin's lid is lifted. Lastly, since the nature of scoop bins requires their openings to be located closer to the floor for access reasons, they are generally within the reach of children and others who are not hesitant to reach into the unsecured bins with potentially unclean hands in order to extract a sample, or even play with the bin contents. In addition, scoop bins also suffer from inventory shrinkage, due to pilferage and accidental spillage.
Gravity-fed bins offer a multitude of advantages compared to other dispensing means, such as scoop bins, including convenience, ease of use and hygiene. However, the ease in which inventory can be dispensed from gravity-fed dispensers sometimes works against itself in that the release mechanism may be easily actuated and thus dispense inventory through the outlet regardless of whether there is a receptacle in place to catch it. This type of dispensing may be accidental, such as a child in a grocery cart tugging on a bin handle, or less so in the case of pilferage or pranks emanating from a portion of grocery clientele and is often referred to as “shrink” or “shrinkage.” In addition to accidental shrink, once a customer dispenses the bulk inventory into a container, all or some part of the dispensed inventory may be consumed by the customer prior to checking out. If consumed prior to being weighed by the retailer for payment, the amount eaten by the consumer amounts to shrink.
Bulk inventory shrinkage adversely affects a grocery retailer in a number of ways. First there is the cost of replacing the lost inventory that has left the gravity-fed bin without payment. Second, shrinkage stemming from accidental spills can make a mess that must be quickly cleaned up. Thus, there remains a need for a reliable, clean and easy to operate bulk inventory dispenser that prevents the dispenser from operating accidentally and once dispensed the inventory is stored in a manner to discourage a customer from eating it prior to check out, thus reducing shrinkage.
The invention disclosed herein addresses and overcomes the shortcomings inherent in providing the consuming public access to self-serve, gravity-fed bulk inventory bins. The present invention provides a means for locking a dispensing actuator until a user of the bin properly slides a receiving receptacle into a receiver located beneath the outlet. Once the receptacle is properly staged the dispensing actuator is unlocked, allowing stored inventory to be dispensed into the receptacle. Once the desired amount of inventory is placed into the receptacle the user releases the dispensing actuator, removes the receptacle from the receiver and places a lid onto the receptacle. Once it is placed in a sealed container dispensed inventory has a much better chance of being be taken to the checkout and paid for without undue shrink.
The bulk product dispenser with receptacle activated dispensing actuator release according to the present invention is preferably constructed of molded plastic, such as polycarbonate, but other moldable or machinable materials and color configurations are anticipated. For food related dispensers, it is also preferable to utilize materials that have been approved by the U.S. Food and Drug Administration and constructed in accordance with food service specifications issued by NSF Int'l of Ann Arbor, Mich.
One aspect of the present disclosure is a locking means for a dispenser of stored bulk inventory. The dispenser comprises a housing, a lower outlet in the housing, a dispensing actuator pivotally connected to the housing, a gate connected to the dispensing actuator and adapted to pivot between a closed position and an open position between a storage cavity and a dispensing cavity within the dispenser, a locking mechanism in communication with the dispensing actuator to prevent its unintentional actuation, an actuator arm proximate the outlet and coupled to the locking mechanism, a receiving container for securing the dispensed inventory for purchase. When a consumer properly places a receptacle into a predetermined position relative to the outlet, the receptacle triggers a releasing actuator, thereby releasing the locking mechanism and allowing the bulk inventory to flow from the dispenser through an opening in the housing and ultimately into the receiving container.
Another aspect of the disclosure is a tamper resistant, locking lid for a bulk inventory receiver for securing dispensed inventory in a receptacle and thus preventing shrinkage.
Further features of the inventive embodiments will become apparent to those skilled in the art to which the embodiments relate from reading the specification and claims with reference to the accompanying drawings, in which:
In the discussion that follows, like reference numeral are used to refer to like elements in the various figures.
A gravity-fed, bulk inventory dispenser 10 as available in the art from Trade Fixtures, LLC of Little Rock, Ark. is shown in
A lid 12 fits atop housing 18 to provide selectable access to the interior of the housing for refilling depleted bulk inventory. Lid 12 may be removable or hinged to housing 18, and may be held in place in any conventional manner, such as a press-fit using mating projections on the lid and/or the housing.
A dispensing actuator 34 is pivotally attached to housing 18. Although dispensing actuator 34 is shown in the form of a handle, additional actuator devices are anticipated which may be manually actuated to articulate a gate that holds back the stored bulk materials. Such additional actuators include, without limitation, an actuator combined with an output portal of the gravity-fed bin. An internal gate (not shown) is arranged to selectively block and unblock an opening (not shown, but internal to the housing proximate dispensing arm 21) between the cavity 16 of housing 18 and output portal 42. The gate is mechanically coupled to dispensing actuator 34 such that the gate, if unimpeded, raises when the dispensing actuator is pivoted downwardly. Under this condition, bulk inventory stored within the cavity 16 of bulk inventory dispenser 10 is permitted to flow from within the cavity, through output portal 42 and, preferably, into a consumer guided receptacle (not shown). For so long as the opening is blocked by the gate, bulk inventory stored in bulk inventory dispenser 10 is prevented from being discharged from the outlet.

In addition to using an actuator arm 112 cooperatively with a receiver 110 and their respective interference with aspects of dispensing actuator 34 in order to prevent its rotation, other dispensing actuator locking arrangements are anticipated by the inventors within the scope of the invention. As a non-limiting example, an actuator may be located on a portion of the dispensing actuator 34 itself and provide interference with the rotation of the dispensing actuator until actuated. Likewise, an actuable safety could be employed at a position on the body of the dispensing bin. Only by moving or holding the safety into an unlocked condition could dispensing actuator 34 be rotated and bulk inventory dispensed.
While this invention has been shown and described with respect to a detailed embodiment thereof, it will be understood by those skilled in the art that changes in form and detail thereof may be made without departing from the scope of the claims of the invention.
