The present invention relates to product displays and dispensers and, more particularly, to gravity feed displays for bottles of liquid, such as beverages.
Liquids, particularly beverages, are frequently sold in bottles of a plastic material or glass material. Where plastic material is used, commonly the bottle has a body configured to accommodate as much liquid as possible, and a neck extending upwardly therefrom that is sealed with a bottle cap. In plastic bottles particularly, the bottle neck is frequently provided with a flange that extends radially outward from the cylindrical bottle neck a short distance, and is located just below the lower end of the bottle cap when screwed on top of the bottle.
Numerous display racks exist for supporting bottles of this type for retail display. Use of shelves is undesirable, because the bottles are pushed to the back easily, and have to be brought forward manually for consumers to access them.
To overcome this, displays, such as the system shown in U.S. Pat. No. 5,586,665, support bottles suspended on racks that are tilted so that the bottles slide toward the front of the display. These systems, however, usually involve a complex structure to prevent the bottles sliding forward altogether off the front end of the rack that makes loading of the bottles difficult or increases the cost of the display unnecessarily.
It is also a drawback that most bottle display racks are accessed by customers by removing therefrom the most recently loaded bottle. As a result, some older product may remain at the rear of the rack for a fairly long time, with the newer bottles being loaded and removed in front of it. This results in retention of the older bottles in the rack longer than is desirable.
It is accordingly an object of the invention to provide a display apparatus that overcomes some or all of the deficiencies of the prior art.
A product display apparatus according to an aspect of the invention, displays a plurality of bottles each having a respective neck with a first width at a first height of the bottle and a wider portion thereabove. The apparatus comprises a sliding bottle support structure including left and right slide structures spaced laterally so as to define a slot of substantially uniform width over at least a lengthwise portion of the slide structures. The uniform width is such that the necks of the bottles extend upwardly through the slot and the widened portion rests slidingly on both the slide structures for forward and rearward sliding movement thereon. The left and right slide structures in the lengthwise portion are inclined forwardly and downwardly at a downward angle relative to level that is in a range of 3 to 7 degrees. The angle and the materials of the slide structures are such that friction between the bottles and the slide structures is low enough that the bottles by virtue of weight thereof slide forwardly on the slide structures.
According to another aspect of the invention, a display apparatus comprises a pair of vertical pillars each supporting a respective upper and lower frame structures. Each frame structure includes a pair of laterally spaced side arms each supported on a respective one of the pillars at a height selected from a plurality of vertical positions so that the upper frame is above the lower frame. Each frame farther comprises first and second cross members supported on and extending laterally between the side arms. A first inclined sliding support member is supported on the cross members and includes a pair of laterally-spaced upwardly-disposed inclined sliding tracks of high-impact polystyrene having about 10% silicone therein supported on the cross members and extending slopingly forward and downward at an incline angle of approximately 5 degrees and defining a slot therebetween. A plurality of bottles is supported on the sliding tracks, the bottles each having a neck portion extending through the slot and a neck flange wider than the slot resting slidingly on the tracks with friction between the flange and the sliding tracks being low enough that the weight of each of the bottles causes the bottle to move slidingly forward along the sliding tracks toward a forward terminal end thereof. The lower frame is at a height such that the first cross member thereof engages a lower portion of a forwardmost one of the bottles on the upper frame and prevents forward movement of the bottle to the forward terminal end of the sliding tracks thereof.
According to another aspect of the invention, a product display apparatus for displaying a plurality of bottles each having a respective neck with a first width at a first height of the bottle and a wider portion thereabove comprises a sliding bottle support structure including left and right slide structures spaced from each other so as to define a slot therebetween of substantially uniform width over a sliding bottle travel path of the bottle support structure formed by the slide structures. The uniform width is such that the bottles are slidingly supported with the necks of the bottles extending upwardly through the slot and the widened portion thereof resting slidingly on the slide structures. The bottle travel path includes a first substantially straight inclined portion wherein the slide structures extend linearly and slopingly rearwardly and upwardly at a first angle, a second substantially straight inclined portion wherein the slide structures extend linearly and slopingly rearwardly and upwardly at a second angle that is less steep than the first angle, and an intermediate curved portion connecting a rearward end of the first substantially straight portion and a rearward end of the second substantially straight portion such that the bottles may move slidingly on the slide structures rearward so as to travel through the first substantially straight portion, through the intermediate curved portion, and through the second substantially straight portion so as to be removed from a front end of the second substantially straight portion. The slide structures in the intermediate curved portion slope downwardly from the rearward end of the first substantially straight portion to the rearward end of the second substantially straight portion at a third angle. The first, second and third angles, and a level of friction between the bottles and the slide structures is such that bottles may be pushed slidingly rearward up the first substantially straight portion to an apex in the bottle travel path at a beginning of the intermediate curved portion, and, when pushed beyond said apex, said bottles slide by force of gravity through the intermediate curved portion and through the second substantially straight portion to the front end of the second substantially straight portion.
Other objects and advantages of the invention will become apparent from the specification herein.

The bottles 3 are supported on a plurality of vertically-spaced frame structures 5 that are releasably secured at pre-selected heights by connection to side pillars 7 of the display rack, which are in turn rigidly connected to a base 9 that supports the display. Alternatively, the pillars 7 may be fixedly secured to a wall behind the display 1.

As best seen in
The angle of the sliding support structures 19, and the structure and materials thereof are such that the bottles 3 supported by their necks, by virtue solely of the weight of the bottles, which overcomes the amount of friction involved, slide on the structure 19 forwardly toward its front terminal end, so that the bottles are biased by gravitational force to move toward the front of the display stand.
The bottles are prevented from sliding completely off the front ends of the support structures 19 by the fact that before the neck of the forwardmost bottle reaches the end of the support member 19, the lower end portion of the forwardmost bottle 3 on each support structure 19 encounters the front rail 17 of the frame 5 below the frame that supports the bottle 3. The lowermost rack 5 has no rack below it and is therefore provided with a front rail armature 21 that extends downwardly therefrom and across the display device 1 at a height such that it also engages the lower end of the forwardmost of the bottles 3 supported by that rack 5 so that it stops moving forward.
The forward terminal end of the support members 19 extends at a length beyond the stopping point at which the neck stops when the bottom of the bottle abuts the front rail 17. To remove the forwardmost bottle from the rack, a person tilts the bottle forward until the widened flange of the bottle neck reaches the terminal end 20 of the support member 19 and passes out of it. At the same time, the bottom of the bottle clears the top of the associated front rail 17, and the bottle is removed easily from the rack. The terminal end 20 extends forward of that point by a distance such that the bottle must be tilted forward to about 30 degrees from vertical before the neck leaves the member 19 and the bottom clears the front rail 17. Geometrically, it is best if the bottle clears the rail 17 before its neck ceases to be supported in the channel member 19, i.e., the terminal end 20 of the member 19 extends further forward than the location thereon supporting the bottle neck when the bottle bottom is high enough to pass over the rail 17.

The interlocking structure includes a series of hooks 24 of a standard configuration for insertion into a vertical slot row as in the standard pillar 7, which are all well known in the art. The top mounting hook 22 is configured with an upward protrusion that requires the side arm 11 to be tilted with its front end upwardly for insertion or removal of the arm 24 to or from the pillar.
Insertion of the arm 11 into the slots of pillar 7 is accomplished by tilting the front end upward, inserting the top protrusion of top hook 22 into the topmost slot to be connected, and then lowering the arm 11 to near level position in which all protrusions 22 and 24 can be and are inserted into the slots in pillar 7. The arm 11 is then pressed downward and the protrusions 22 and 24 all have downward disposed recesses that catch on the slots and hold the arm 11, and the attached frame 5, out in a cantilever fashion.
Tubular front rail 17 extends horizontally between the forward end terminal portions 25 of side arms 11, to which it is welded at both ends. Center cross arm 15 is attached fixedly to a connection structure generally indicated at 27 which secures the cross member 15 against upward and downward movement. The rear cross member 13 receives a connection structure as will be described herein and is fixedly secured by a pressure fit to extend perpendicularly between the rearward end portions 23 of the arms 11.
The front rail stop structure 21 for the lowermost frame 5 is shown in greater detail in

The beam 19 is straight over its entire length and supported so that it extends forwardly and downwardly at an angle relative to the horizontal upper portion 37 of the side arm 11. The beam 19 is also secured by a screw or other fixed attachment mechanism to cross arm 15, which is a tubular beam, and also to the underside of cross member 17, which is also a tubular member. These beams 13, 15 and 17 are positioned to maintain the angle of the downward slope of the sliding support structure 19.
Referring to
The material that the structure 19 is made of is high impact polystyrene. This high impact polystyrene (HIPS) is a material that includes from 5 to 11% silicone, and in the particularly preferred embodiment 10% silicone. Substantially greater than 11% silicone in the HIPS material results in a softer polystyrene beam that might have difficulty supporting the weight of a very large number of bottles suspended therefrom. On the other hand, reducing the amount of silicone substantially below 5% or even 7% silicone increases the friction on the surface of the polystyrene and may prevent the bottles from sliding forward.
Referring to
As discussed previously, to prevent the bottles from sliding of the tracks 49 and out of the sliding support structure 19 altogether through the open front end of the beam 19, the lower portion 55 of the bottle encounters a rear portion of the front cross bar 17 of the lower frame 5 just below the frame from which the bottle 53 depends. This contact point is preferably close to the bottom so that it is relatively easy to withdraw the bottle from that position even for a person that is well below the level of the racks 5.
The front end 57 of the sliding support structures 19 extends substantially beyond the point at which the neck portion 59 of the forwardmost bottle 53 is in contact with the channel 19. The forward end 57 extends substantially beyond this point, and with all the angles requires that a person removing the bottle 53 from the rack 1 is required to tilt the neck 59 forward by about thirty degrees so that it can pass out of the space inside the channel 19 and passes over the stop structure 17. This dimensioning allows for a fairly short person to access a fairly high shelf or rack of bottles.
This interaction between the bottles of a first frame 5 and the cross beam 17 of the frame 5 just below it is not possible with the lowermost shelf 5. For the bottles in the lowermost shelf, the cross beam structure 21 is provided, which similarly abuts the lower ends 55 of the bottles or the forward most bottle in a way that allows for withdrawal of the bottle by tilting it forward at about thirty degrees so that the neck and the widened portion thereof can pass out through the open front end of extrusion beam 19. The positioning of the front beam 21 is such that the angle is the same for this frame 5 as well.
All of the bottles in the rack are removed by customers in this way. Similarly, the bottles are each loaded by tilting them forward about 30 degrees, passing the bottom of the bottle over the front beam 17, and then inserting the neck of the bottle into the beam 19.

The terminal end 20 is spaced from the stopping point A by a distance x that is such that the bottle 101 clears the end when tilted forward with its centerline CL at an angle β of about 30 degrees from the vertical, shown as line V. At this angle β, the center of gravity CG of bottle 101 is above the cross beam 17, which results in weight of the bottle 101 resting on the beam 17. The customer or user then withdraws the bottle 101 forward, and it is lifted over or slides over the cross beam 17.
Placement of bottles into the rack is similar but in reverse. When a bottle is to be loaded in the rack, the bottle is tilted and inserted in the rack above the cross beam 17. The lower portion of the bottle 101 is pushed against the bottle 111 behind it, pushing bottle 111 upward along the sliding track 49 against the biasing of its weight to slide forward. When the neck 105 reaches the end 20 of the support member 19, the neck 105 is fit into the channel 19 so that the flange of the neck rests on and is slid backward until it reaches the stopping point A, to the positions shown in
Referring to
The arrangement of the rack can be compressed somewhat vertically by eliminating the cross beam 15 on the lower racks. That is possible if the loads created by the bottles on the rack can be supported by the member 19 supported only by front rail 17 and rear rail 13. In that case, there is additional clearance of the bottles of the higher rack above the sliding member 19 of the rack below, allowing the side arms 11 to be vertically closer together.
The laterally inward edges of the upper surfaces of lips 129 are each provided with a respective linearly straight track of material 131 fused, glued, or fixedly secured by some other method, thereto. The support member 121 is supported as in the previous embodiment by structure that holds it cantilevered out at a downwardly and outwardly inclining angle. The neck flanges of the bottles rest on the tracks 131 and slide downwardly on the tracks 131 by gravity until the forwardmost bottle engages the front rail as described above.
These tracks 131 are of a material having a lower coefficient of friction than the material of which the rest of the support member 121 is composed. The tracks 131 of the support member 121 are of HIPS containing from 2% to 10% silicone, and most preferably 4% to 6% silicone, or about 5% silicone. The remainder of the support member 121 is of HIPS containing little or no silicone, which renders the material stronger. The slipperiness of the track material allows a relatively mild incline while the bottles will still slide down the support member on the tracks 131 to the front of the display, The slope of the incline may be less than 8 degrees, and is preferably from 5 to 6.5 degrees.
The strength of the channel member is enhanced by the walls 123 and 125 being of HIPS containing no silicone or very little silicone. The bending over its length when loaded with bottles is therefore reduced. Also, the channel is strengthened against the possibility of the bottles being somehow twisted so as to pry apart the lower lips 129 and tracks 131 by the use of the stronger HIPS material, and also by a rounding of the corners 133 between the top wall 123 and the side walls 125. The rounded corners have an inside radius of curvature of greater than 0.15, and preferably between 0.2 and 0.35 inches, and most preferably about 0.25 inches. This curvature strengthens the side walls 125 support against the spreading apart of the lips 129.

Channel members or first and second sliding support structures 161 and 163 are configured similarly to the channel members of any of the previous embodiments. Each pair of channel members 161 and 163, together with the attached bridge unit 151 form a bottle travel path from a left hand-loading front portion 167 of member 161 through which bottles may be loaded and pushed rearward by a user so that they proceed to the bridging support structure 151, through which they proceed by sliding by force of gravity to the rear of the next adjacent channel member 163 to the right, and then slide forwardly down the right hand channel member 163 to a forward end 169 thereof for display and removal from the apparatus by customers. The point of connection between the sliding support structures 161 and the bridging support structures 151 defines an apex in the bottle travel path. The bottle travel path is straight to this apex, which allows bottles to be pushed rearward to that point. The bottles are pushed past the apex into the bridging support structure 151, where the sliding support structures start to curve to the right and also to slopingly descend, so that the bottles proceed beyond this apex point and through the second sliding support structure 163 solely under the force of gravity, i.e. without receiving any push by a user. First sliding support structures 161 have an incline angle upward and rearward that is greater than the downward incline angle of the second support structures 163. Bottles that do not reach the apex of the bottle travel path therefore slide forward and downward toward the front ends 167 of the first channel members 161. Bottles in the display therefore all move to the forward ends of channel members 161 and 163, as has been described in previous embodiments.
The bottles at the front ends 167 and 169 engage the front cross member 157 of the frame below it, as discussed above. The lowermost frame has an armature 171 that supports a lower cross beam 173 that abuts the lower ends of the forwardmost bottles in the lowest frame of sliding support structures 161 and 163. The operation of the display id essentially the same as in the previous embodiments. The main differences are the bridging units 151 at the rear, and the provision that loading of the display is preferably at the odd-numbered channel members 161, which rotates older stock to be pushed over the apex to return via channel member 163. The arrangement means that the incline angle of slope of channel members 161 is steeper, e.g., 5 to 7 degrees, most preferably about 7 degrees, as compared to the incline angle of the channel members 163, which is approximately 3 to 5 degrees, and most preferably about 5 degrees. The incline of the curved sliding tracks in the bridging structure 151, which will be described in eater detail below, is about 3 degrees, meaning that the rear end of the left channel member 161 is slightly higher than the rear end of the right channel member 163.
A generally arcuate housing 181 connects between the sleeve structures 165. The housing 181 includes an upper wall 183 with apertures 185 and 187 therein through which screws 158 extend to secure the bridging structure 151 to the underside of cross member 159. On aperture 185 is basically flush to the upper surface of the housing 181, while the other aperture 187 extends through a spacer structure 189 that ensures an angled slope of the housing and the sliding tracks therein. Gusset 184 reinforces the curved structure.
The internal structure of the bridging unit 151 is best seen in
The connection of the bridging support structure 151 to the two sliding support structures 161 and 163, and the resulting bottle travel path created by this combination of components is best seen in
Channel members 161 and 163 have a cross section as seen in
Channel member 161 extends straight rearward at an upward first angle of about 5 to 7 degrees, preferably 7 degrees. Bottles slide on sliding tracks 49 on lower flanges 47 of side walls 43 of the channel 161. At the rear end 201 of channel 161, sliding tracks 49 meets with the front portions 203 of sliding tracks 199 of the bridge unit 151. This meeting point is indicated at line Z in
Up to this location or apex Z, the channel 161 and its sliding tracks extend slopingly upward and rearward at a constant angle of approximately 7 degrees. The front portions 203 are also straight as they meet the end portions 201 of the channel 161 tracks. However, the end portion tracks 199 immediately extend downwardly after the apex Z. The angulated difference between the upward slope of channel support 161 and the downward progression of the tracks 191 in the bridge structure thereafter result in the point indicated at Z being the highest point or apex of the bottle travel path.
At Z, the tracks 199 and 49 meet at the same height, although the difference in the angles of the sliding tracks 49 and 199 creates a slight bump or corner or angled ridge between the tracks 49 of channel 161, proceeding upward and rearward at an angle of about degrees, and the tracks 199 of bridge unit 151, proceeding downward and rearward at an angle of about 3 degrees. Bottles are pushed rearwardly to this apex Z and over the ridge as a corner. After passing the apex Z, the bottle immediately slides by gravity down the sliding tracks 199, which extend slopingly downwardly from Z onward at the downward angle of approximately 3 degrees. The tracks 199 also start to curve at this point. The tracks 199 are at the same height taken at points of a radius through the centerpoint of the arcuate path of the bridging structure unit 151, or expressed another way, the tracks 199 descend in parallel spirals, so that the bottles hang vertically as they slide along the tracks 199.
The friction and angles of the bridging structure are such that bottles passing the apex Z slide downward purely by force of gravity around the arcuate portion 181 to the lower ends 205 of the curved tracks 199, which meet up with the rear ends 207 of the sliding tracks 49 on the flanges 47 on the side walls 43 of channel 163. At the point of meeting Y, the tracks 199 and the tracks 49 of channel support member 163 are at the same height to allow sliding movement of bottles between them, but there is a slight difference in angles, in that the tracks 199 descend at approximately 3 degrees coming to point Y, and the tracks 49 of member 163 extend slopingly forward and downward away from the meeting point Y at approximately 5 degrees. The result is a second slight downwardly angulated ridge of the 2 degrees steeper change in slope at Y. The ridge however is not an obstruction to the sliding travel of the bottles, and bottles slide over and past this second ridge easily by force of gravity, and also without human involvement, from the bridging structure 151 into the channel 163.
Channel 163 extends straight linearly downward and forward from the bridging unit and sleeve 165 at a constant sloping angle of about 5 degrees, and the bottles slide down the tracks 49 to the forward end of the channel 163 to abut the lower cross member and await removal by a customer, as can be seen in
Bottles are preferably loaded into the left hand channel members 161, and pushed rearward to fill the channel member 161, after which the rearmost of the bottles passes the apex Z and then slides around and down to the front end of channel member 163. The result is a tendency to push older bottles at the rear of the rack to slide around and be offered to consumers art the front of the second channel member 163, so that bottles are less likely to be kept at the rear of the rack for long periods of time.
The example of
It will be understood that the sliding tracks 49 and 199 that slidingly support the bottle necks may be formed of material that is especially low in friction, e.g., HIPS with silicone levels of above 10%, with the material be applied as material different from the remaining structure of the channels 161 and 163 and the bridging structure 151. For example, the sliding structures may take the form of the linear bead of material 131 of
