The present disclosure relates to the field of bulk dispensing bins, particularly those for use by consumers at point-of-sale installations. More specifically, the present disclosure relates to features to limit direct contact between a user and the dispenser.
Bulk dispensers, and more particularly gravity-feed bulk dispensers are known and used in commercial settings for self-service portioning of bulk materials, for example foods. Traditionally, gravity feed bins for dispensing bulk materials 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) or food (e.g. nuts, cereals, grains, pastas, coffee (beans or ground), dried soup mix, candies, spices). Generally, the bins include an enclosure having an inlet at an upper end through which the enclosure is filled, an outlet at a lower end for dispense of the material, and a flow control device located between the upper and lower openings for controlling an amount of materials being dispensed. In operation, as the material is being dispensed gravity pulls the remaining material in the enclosure towards the lower end to replace dispensed material. These types of bins generally include a downwardly curving inner wall that forms a chute to channel the dispensed materials in a receptacle adjacent the outlet.
Examples of known gravity feed bins are found in U.S. Pat. No. 4,903,866 entitled, “Gravity Dispensing Bin System”; U.S. Pat. No. 5,437,393, entitled, “Apparatus for Delivering Bulk Foods”; U.S. Pat. No. 6,182,864 entitled, “Bulk Food Dispensing Apparatus”; U.S. Pat. No. 6,241,123 entitled, “Bulk Food Dispensing Apparatus”; U.S. Pat. No. 10,450,152 entitled, “Expandable Gravity-Feed Bin”; and US Pat. App. Pub. No. 2019/0092617 entitled, “Expandable Gravity-Feed Bin.” Each of these are incorporated by reference in their entireties.
In an example of a gravity-feed dispenser for storage and dispensing of bulk material, the gravity-feed dispenser includes a compartment configured to receive and store bulk material. A spout is connected at one end to the compartment and open at a dispensing end. A gate separates the compartment from the spout. The gate is operable to open and close to selectively permit bulk material to pass from the compartment into the spout. An actuator is movable relative to the spout and mechanically connected to the gate such that movement of the actuator operates the gate to reversibly open and close. Movement of the actuator concurrently reversibly positions the actuator to a dispensing position below the dispensing end of the spout, wherein dispensed bulk material passes through the actuator.
In further examples of the gravity-feed dispenser, the actuator includes a spout. The actuator is pivotably connected to the spout of the dispenser and wherein in the dispensing position, the spout of the actuator is positioned below the spout of the dispenser. A pivot housing is releasably secured about the spout of the dispenser. The actuator is pivotably secured to the pivot housing. At least one handle arm is mechanically connected to the gate. The at least one handle arm and the gate rotate about a same axis with respect to the compartment to open and close the gate. A linkage is pivotably connected between the at least one handle arm and the actuator. The at least one handle arm is a pair of handle arms with a first end of the linkage pivotably secured between the pair of handle arms, and wherein the actuator comprises a pair of lever projections that extend from the actuator, a second end of the linkage pivotably secured between the pair of lever projections. A force applied to the actuator rotates the actuator relative to the spout of the dispenser and the force is transferred to the gate through the linkage and the pair of handle arms to open the gate. The linkage includes identifying information regarding the contents of the dispenser.
In additional examples of the gravity-feed dispenser, a spout extension may extend away from the spout of the actuator. A bowl adapter can be secured about the spout of the actuator. The bowl adapter may define an aperture configured to receive the spout of the actuator. The bowl adapter includes a sidewall configured to engage an interior surface of a bowl. The spout of the actuator may further include a lip configured to abut a surface of the bowl adapter. The bowl adapter and the spout of the actuator further include engagement features configured to retain the bowl adapter in engagement with the spout of the actuator. A bowl adapter may be secured the actuator. The bowl adapter may be configured for engagement with a bowl.
An example of an actuator assembly for a gravity-feed dispenser includes a pivot housing configured for attachment about a spout of the gravity-feed dispenser. An actuator is pivotably attached to the pivot housing at a pivot point. The actuator includes a pair of lever arms extending away from the pivot point. A pair of handle arms are configured for rotatable connection to the gravity-feed dispenser. A linkage is pivotably connected at a first end to the pair of handle arms and pivotably connected at a second end to the pair of lever arms. The linkage is configured to movably connect the actuator with the pair of handle arms.
In examples of the actuator assembly, the actuator further includes a tubular spout extending away from the pivot housing. The actuator assembly may further include a bowl adapter configured to move with the actuator assembly and to receive an indirect force applied thereto through a bowl placed in engagement with the bowl adapter. The actuation assembly may further include a gate engaged with the pair of handle arms and configured to rotate with the handle arms. The linkage may further be configured to extend through the interior of the spout of the dispenser.
An example of a method of retrofitting a gravity feed dispenser that includes a handle, a gate, a compartment, and a spout to include an actuation assembly includes removing the handle from the gravity feed dispenser and removing the handle from mechanical connection to the gate. The pair of handle arms are secured through holes in the dispenser through which the handle was mechanically connected to the gate. The pair of handle arms are mechanically connected to the gate. The actuator is pivotably secured to the spout of the gravity feed dispenser. The linkage is pivotably connected between the pair of handle arms and the lever arms of the actuator.
In an example of the method, the pivot housing is secured about the spout of the gravity feed dispenser. The actuator is pivotably secured to the pivot housing.
A customer initiates the flow of the bulk product by actuating handle 34 in the direction of arrow 40. The customer holds a receptacle (not shown) below an outlet 42. The customer holds the handle 34 with one hand while holding the receptacle with the other. Actuation of the handle 34 opens a door (not depicted) internal to the bulk dispenser 10 connecting the first cavity 20 to the third cavity 22. Under the force of gravity, material flows from the first cavity 20, through the third cavity 22, out the outlet 42 and into the receptacle, in that order. After dispensing a desired amount of material into a receptacle, the customer releases handle 34 and biasing devices (not depicted) interact with the front piece 18 and the door to return the handle 34 back to the first position in which the rotating door separates the first cavity 20 from the third cavity 21, i.e. the normally closed position of the handle and door. As previously indicated, other examples of gravity feed bins are known and incorporated by reference in their entireties.
Consumers may use disposable, single-use receptacles (e.g. cups or bags) or may use reusable storage containers to collect the product dispensed from the dispenser. Some consumers and retailers find preference for this type of product sale as it generally requires less packaging and therefore less consumer waste. Further, due to supply chain efficiencies, the products can be sold at a more economical price than compared to pre-packaged portions. Lastly, some consumers may prefer the interactivity of the dispense of products from a bulk resource and the control over the volume of product acquired.
However, consumers and retailers have increased concerns regarding the potential for disease transmission by successive operations of these communally available dispensers. The interactivity of the operation of common bulk dispensers has consumers repeatedly placing their hands on the handles of the dispensers. This could potentially transfer microbes, viruses, and/or other disease vectors from one customer to a subsequent customer using that dispenser. Such transfer could occur across several customers across a series of transactions with the same dispenser. One way to limit this transfer potential is with protocols for cleaning, sanitation, and/or disinfection, which require schedules, supplies, and additional worker actions.
The dispenser 100 exemplarily includes similar first cavity 20, second cavity 21, and third cavity 22 as described above. Such first cavity 20, second cavity 21, and third cavity 22 may be similarly defined by side walls 14, 16, front wall 18, and a lid 12 as described above as well. While it is recognized that these features may remain the same between the dispensers of
The dispenser actuator assembly 110 includes a spout actuator 112 which rotates relative to a pivot housing 114. The pivot housing 114 is secured about a spout 124 of the dispenser 100. The spout actuator 112 exemplarily includes a tubular spout 132 and may optionally include a spout extension 116 that extends from the tubular spout 132 and faces the user. The spout extension 116 can help to direct the dispensed bulk product into the receptacle during dispense. The spout actuator 112 is connected to a pair of handle arms 118 by a linkage 120. The handle arms 118 are rotationally connected to the front wall 18 of the dispenser 100. As exemplarily depicted in
The spout actuator 112 is pivotably secured to the pivot housing 114 at a pivot point 134. The pivot point may be defined by the interaction of an axle projection 136 from an exterior of the pivot housing 114 with an axle aperture 138 of the spout actuator 112. It will be recognized that other pivot connections between the spout actuator 112 and the pivot housing 114 may be made within the scope of the present disclosure.

With the receptacle thus positioned relative to the spout actuator 112, the user placed a force upon the spout actuator 112 through the receptacle in the direction of arrow 164. This force rotates the spout actuator 112 about the pivot point 134 in the direction of arrow 164. This applied force is transferred through the connection of the lever arms 146 to the linkage 120 as described above, moving the linkage 120 in the direction of arrow 166. The movement of the linkage 120 in the direction of arrow 166 transfers the applied force to the handle arms 118, causing the handle arms 118 to rotate relative to the front side 18 about the projection 154 in the direction of arrow 168. Because of the engagement between the handle arms 118 and the gate 122 by way of the resilient snaps 156, the gate 122 rotates in the direction of arrow 168 along with the handle arms 118. This moves the door 162 of the gate 122 away from the compartment 20 opening the compartment 20 to the compartment 22 so that the bulk product from the compartment 20 can move by way of gravity along the path of arrow 170 out of the opening 130 into the receptacle.
Thus by way of the mechanical connections just described, the force on the spout actuator 112 indirectly applied by the user through the receptacle simultaneously moves the components of the spout actuator 112, linkage 120, handle arms 118, and gate 122 from the closed positions depicted in
It will be recognized that the example just described is but one example and that other variations will be recognized based upon the disclosure provided herein. In some examples, the spout actuator 112 may rotate through 45 degrees, while in other examples it may be less than 45 degrees, exemplarily 25 degrees or 35 degrees, while in further examples, the spout actuator 112 rotates greater than 45 degrees, exemplarily 60 degrees. The spout actuator 112 may exemplarily end with the tubular body 132 in a vertical orientation relative to the spout 124, while in other examples, the spout actuator 112 may remain at an angle relative to the spout 124 when positioned in the open or dispensing configuration.
The extension portion 176 further includes projections 186 that extend laterally away from the extension portion 176 at locations below the pivot connections 147 between the actuator 112 and the linkage 120. The projections 186 are configured to engage the lever arms 146 of the actuator 112 to help to define the closed or resting position of the actuator assembly 110.
In operation, a user positions a bowl 174 through the opening in the bowl adapter (between the arms 178 and the bowl tray 180 and places a downward force on the bowl 174. This force is transferred to the bowl tray 180 and the linkage 120, pulling the linkage 120 down and the gate (122
The bowl adapter 188 includes a lip 196 and an exterior side wall 198. The lip 196 and the sidewall 198 are exemplarily circumferential and define respective outer extents of the bowl adapter 188. As shown in
The bowl adapters 188 may be integrally formed with the spout actuators 112 or may be separate pieces as shown in
The bowl adapter 172 includes arms 178 which connect to the linkage 120 and to the lever arms 146. Apertures 206, 208 are exemplarily formed as keyway apertures and are configured to receive projection 200 from the lever arm 146 and projection 202 from the linkage 120, respectively. The projections 200, 202 exemplarily include flanged tops and a portion of the apertures 206, 208 are enlarged to receive the respective flanged tops, while the projections 200, 202 may mechanically come to rest within a narrower portion of the apertures 206, 208, to secure the bowl adapter 172 to the linkage 120. The projection 200 of the lever arm 146 in combination with the projection 145 of the lever arm defines a common connection axis of respective points of the linkage 120, lever arm 146, and the arm 178. In an example, because the bowl adapter 172 is connected to the linkage 120 at four points (e.g. the opposite side of the actuator assembly 110 than pictured in
The bowl adapter 172 includes a bowl tray 180 which includes a lip 182 and sides and a bottom that define a depression 184. The depression 184 and the lip 182 are configured to engage the bottom, sides, and lip of a corresponding bowl (not depicted) to receive the bulk product. The bowl tray 180 is configured to engage approximately half of the bowl, or for example, is semi-circular in shape. A semi-circular or approximately semi-circular shape of the bowl tray 180 provides an opening between the sides of the bowl tray 180 dimensioned to receive the diameter of the bowl and is configured for engagement with approximately half of the bowl.
The arms 178 extends rearward from the linkage and laterally exterior of the spout 124. As described above, the arms 178 are also positioned laterally exterior of the pivot housing 114 and the lever arms 146. That is, the lever arms 146 move in a plane between the spout 124 and the arms 178. The arms 178 further connect to a dispensing shield 210. The dispensing shield 210 extends downward from the arms 178 and connects the arms 178 to the bowl tray 180, and specifically to the lip 182 of the bowl tray 180. The dispensing shield 210 is exemplarily partially frustoconical in shape, flaring radially outward such that a radius of the shield 210 is smaller at an edge 212 than at a base 214 where the dispensing shield 210 connects to the exterior of the lip 182.
In operation, the user positions a bowl within the bowl tray 180 and places a downward force on the bowl. This downward force is transferred through the bowl adapter 172 and the linkage 120 to the handle arms 118 to open the gate to dispense the bulk product. The lever arms 146 rotate with the linkage 120 and the bowl adapter 172 to define the position of the bowl adapter 172 relative to the spout 124 of the dispenser. In the dispensing position, the bowl tray 180 is located below the spout 124. In the dispensing position, the edge 212 of the shield 210 is positioned proximate to the opening 42 of the spout 124, and the shield 210 helps to direct dispensed bulk product from the spout 124 into the bowl in the bowl tray 180.
In
In examples as provided herein, the dispenser actuator assembly 110 is exemplarily provided as a retrofittable component package suitable for modification of existing gravity feed bulk dispensers 10 as are currently available, for example as described above with respect to
In another example, the linkage operatively between the gate and the spout actuator may be routed internally to the spout. In such an example, the linage may comprise two linage bars that are each secured to an internally routed gate axle from which arms extend. The spout actuator may be pivotably secured to the spout or the pivot housing with locking axles that extend through the spout actuator and through the spout interior of the spout. The locking axles may connect to linkage actuator arms. The linkage bars extend between the arms of the gate axle and the linkage actuator arms. The linkage bars transfer movement of the spout actuator to the gate to open and close the gate.
In still further examples, a handle may be actuated by the receptacle placed in contact with the handle, the handle actuated by rotation or translation to open the gate inside the dispenser, dispensing the product into the receptacle. An example of such handle may include a funnel. The receptacle (e.g. a single-use bag or a reusable jar) is placed about the funnel, and the user transfers force through the receptacle to the funnel and the rest of the handle. This rotates the handle, which opens the gate on the inside of the dispenser while rotating the funnel into position below the spout so that the receptacle receives the dispensed product. It has been discovered that a challenge is presented to achieve alignment of the funnel with the spout in coincidence with the gate opening. In still other examples, other arrangements of mechanical connection between the door and the handle may be used. In one example, the handle may rotate about a separate pivot point secured to the spout and apart from the pivot point of the gate. Gearing between the handle and the gate may reduce an angle through which the handle must rotate, and keep the handle and funnel in alignment with the spout. In another example, the handle and funnel may remain in alignment with the spout, but the handle moves vertically to actuate the gate.
In a still further example, the handle is integrated with the spout. The handle rotates the entire spout to actuate the gate. This example, along with others in this disclosure can be reversed in actuation, for example, may be configured to actuate on either a push or a pull rotation. In an example, a consumer rotates the spout towards themselves, to a point at which the angle of the spout matches the angle of the bin chute, this directs the product past the gate and through the spout into the receptacle.
