6 Claims. r 34-88) This invention relates to improvements in display and vending cases for retail trade and more particularly concerns such a case having a novel hopper construction for the sale of goods in bulk, as for example toasted nuts.

One object oi the invention is to provide a new and improved case of this character in which an enclosing casinghas confined therein a unitary hopper structurer including one or more hopper bins to which access may readily be had through the top of the casing for the purpose of lling the same and through the back of the casing for yending purposes.

Another object is to provide a display case comprising an external casing structure and a hopper unit therein which is readily separable from the casing so that all parts may be easily cleaned.

Another object is to provide such a case in which the enclosure has a display window in the `front Wallthereof and the hopper structure has means coacting with the window to produce one or more pockets for receiving a portion of the bulk goods to form a constant display separated from the Variable contents in the hopper.

Another object is to provide a new hopper type display case including a casing having a large window opening closed by a suitable window pane held in vposition by the hopper unit within the case.

Another object resides Vin the provision of an improved case for vending bulk goods such as nuts from a `hopper and which includesheat radiating means for warming the nuts in the hopper and especially those that are next to be withdrawn from the case.

A further object is to provide a novel case of this character having a front wall including a large transparent window divided by the hopper structure into two parts, one for displaying the goods for sale and the other for advertising display. Y

Still another object resides in the provision of a hopper case of `this character having a novel top closure construction.

An additional object is to provide a novel display and vending case in which the front Wall is of a novel, rearwardly slanting construction and the top closure includes novel means for illuminating the front of said wall and the merchandise behind the window thereof.

Other objects and advantages will become apparent in the following description and irom the accompanying drawings in which:

While the invention is susceptible of various modications and alternative constructions, I have shown in the drawings and will herein describe in detail, the preferred embodiments, but it is to be understood that I do not thereby intend to limit the invention to the specific forms disclosed, but intend to cover all modifications and alternative constructions falling within the spirit and scope of the invention as expressed in the appended claims.

In`a preferred form of the invention, a small number of units are constructed to be quickly and easily tted together in a minimum of assembly operations to produce a compact sanitary and eilicient` display and vendinghopper. Accordingly, a casing shell -unit is provided which is open at the top and back and which has a iront wall consisting largely of a window. Withinthe shell is mounted a hopper unit having a plurality of hopper` bins, and the top and back of the shell are enclosed by removable top and back units provided with doors through which access is given to the hopper bins for, respectively, nlling and vending purposes. An attractive constant display of the goods on sale is maintained within display pocketsback of the front wall window independently of the variable bulk of the goods in the hopper bins. In the wndowbelow the pockets may be an illuminated advertisement. Although the case is adapted for various kinds of bulk goods it is eminently suitable for retail sale of nut meats which may be kept in a fresh and appetizing condition by heating the same thoroughly within the case before sale.

Referring more particularly to the drawings, the display and vending case includes generally (Fig. 2) a shell I0 having the top and back thereof open and forming the body unit of the casing for enclosing the case. Within this body shell is mounted an upright hopper unit I I; and the back and top of the shell are enclosed by a back unit I2 and a top unit I3, respectively. All of the several unitsI may be separately fabricated from suitable sheet metal parts which are bent to shape and welded or otherwise secured in the necessary relationships.

The body shell IIJ in the present instance serves as the principal supporting means of the case and is provided with a generally rectangular; inverted pan-shaped base I4 from which rise a fiat front wall I5 and spaced parallel side walls Il. Preferably the front-and side walls are formed of a single U-shaped sheet of metal and an inturned retrovert flange I8 reinforces the top edges thereof. As shown, `the side walls I may be formed narrower at the top and wider at the bottom, with the upper edge of the wider portion extending forwardly at a slant to meet the rear edge of the narrow portion.

Framed by the front wall is a large window opening I9 which is closed by a window pane 20 lying flush with the inner face of the wall below the reinforcing flange I8 and resting at its lower edge upon the adjoining portion of the base I4.

The hopper unit I I is dimensioned to fit snugly within the casing shell IU and includes a plurality of individual compartments or hopper bins in which several varieties of nuts may be stored. In constructing the hopper unit a `plurality of similarly dimensioned side wall panels 2I and dividers or partition panels 22 are mounted vertically in equally spaced parallel relation upon a bottom wall 23 to form separated bin spaces. Herein a pair of side walls and a pair of partitions combine to form three equally dimensioned bin spaces, but the number and dimensions of the bin spaces may, of course, be varied to suit requirements.

Throughout its major area, the bottom wall 23 is horizontally arranged to rest upon the base I4 and may be secured thereto by bolts 23a; but a substantial forward portion 24 of the bottom wall is inclined upwardlyand forwardly at approximately forty-five degrees to meet the forward edges of the side wall panels 2I and the partition panels 22 in a horizontal plane substantially spaced from the top edges of the panels.

Slanting upwardly and rearwardly in each lbin space, substantially perpendicularly from an intermediate point ofthe inclined bottom portion 24, is a hopper plate 25. Herein this plate has its lower edge in predetermined edgewise spaced relation to the inclined bottom portion and its top edge near the top rear corners of the vertical bin panels between which it is secured.

upwardly past the overhanging reinforcing flange I8.

The horizontal forward edge of the inclined bottom portion 24 meets the window pane 20 along a line substantially below the top of the pane and preferably slightly below the horizontal center thereof. Through this arrangement the window pane 20 coacts with the bottom portion 24 to form the front walls of hopper bins 26, the hopper plates 25 forming the rear walls thereof. Bulk nuts are placed into the hopper bins 26 at the top and feed in controlled flow Ydownwardly and rearwardly through the limited space between the edges of the respective hopper plates 25 and the inclined bottom portion 24 in a relatively thin layer onto the horizontal rear portion of bottom wall 23 in the substantial spaces below the hopper plates. The rear portion of the bottom Wall 23 forms a tray from which the nuts may be easily scooped up for sale and has a retaining flange or curb 2l along the rear edge thereof.

The nuts stored in each of the hopper bins 26 may be viewed through the window 2U. However, as sales are made the quantity of nuts will vary, and the invention therefore contemplates the provision of flat vertical bulkheads such as glass plates 28 mounted in limited rearwardly spaced parallel relation to the window 2U to provide pockets 2Q for receiving constant displays of nuts separated from the bulk in the several hopper bins 25. Herein the bulkhead plates 28 are slidably received within opposed vertical channel guides 3B mounted upon the inner faces of the end walls 2i and partition panels 22 of the hopper bins 26 and rest at their lower edges upon the inclined bottom wall portion 24. The display thus provided will be unaffected by Variation in the bulk of the nuts behind the bulkheads. When it is desired to remove the bulkhead plates 28 as for removing the nuts in the pockets 29 the plates may easily be slid up in their guides 38, the nuts dropping back into the hopper bins.

A further advantage of the bulkheads 28 is that should the window 28 be accidentally broken or require replacement, the principal bulk of nuts in the hopper bins will not be contaminated or spilled, the only possible loss being of the small quantities of nuts in the display pockets 29. Moreover, the hopper unit II may be shifted out of the casing shell Ii) and replaced without disturbing the nuts in the hopper bins.

A window space below the meeting edge of the inclined bottom portion 24 may be utilized for display advertising purposes and if desired an electric light 3l may be suitably mounted in the triangular compartment below the inclined portion. Preferably the socket for the light is carried by the inclined bottom portion 24.

Nut meats to be most palatable should be freshly toasted and most kinds of nuts are possessed of the best flavor when warm. Accordingly, a radiant electric heater 32 is mounted below each hopper plate v25 and in such a position that the heat radiating therefrom will be directed in part toward the nuts in the lower portion of the associated hopper plate but primarily downwardly upon the nuts within the tray therebelow, thus assuring that the nuts which are next to `be sold will be thoroughly warmed. Because the layer of nuts fed to the bottom tray 23 is fairly thin warming thereof is facilitated. To facilitate .passage of heat 'toward the nuts in the lower portions of the hopper bins l26, the hopper plates 25 may tbe perforated las shown at 33.

Narrow horizontal shelves 34 mounted below the topA edges of the hopper plates 25 support the heaters 32 therebelow. These shelves 34 may have polished under surfaces opposing the heaters 32 for reflecting downwardly upon the nuts in the tray therebelow radiant heat which is directed upwardly from -the heaters. The several reil-ector shelves 34 are alined to provide a partitioned duct thereabove for receiving the necessary electric wires and the like for the heaters.

Following placement oi' the unit II 4in the assembly, the rear closure unit I2 is secured in position. vThis closure unit includes an upper section 35 arranged to be mounted iixedly and a hingedly connected lower or door section 31. The upper section has end flanges 38 which embrace and are secured to the vertical rear margins of the side walls I1 by means of screws 39. rIj'he door section 31 loosely engages the slanting `rear edges of the side walls I1 and has a flange 40 along its lower edgewhich in closed position overlaps the curb 21. A handle 4I permits the door section 31 to be opened easily to give access to the delivery end of the hoppers, and a detent 42 and a spring clip 43 form a friction catch by which the door section 31 may be held open againstthe fixed section 35.

1 The top closure unit I3 completes the assembly and in the present instance comprises connected `front and rear portions 44 and 45, respectively,

the unit being removably mounted in closing relation to the hopper unit II. As shown the front portion 44 is dimensioned to provide a tray of substantial depth adapted for receiving packaged merchandise for display. The tray has open retrovert flanges 41 along the front and sides thereof for engaging the upper margins of the front wall I and the side walls I1 of the body shell I 0, such walls extending suiiiciently above the top of the hopper unit II for this purpose. If desired, the side walls I1 may be provided With shelf angles 48 which overlie the hopper side wall panels 2| and upon which the bottom of the tray 44 may rest. At the rear, the tray 44 may have an upstanding back plate 49 carrying a price card holding strip 50 on its front face.

When it is desired to gain access to the display pockets '29 which open upwardly below the tray 44 the latter may easily be lifted away.

Hinges 5I connect the door portion 45 substantially in the plane of the bottoni of the tray 44 so that the door portion may be swung upwardly to give access to the tops of the hopper bins 26 for'fllling the same.

Along its rear edge, the door portion 45 has a substantially right-angle flange 52 adapted in the fully closed position of the door portion to frictionally overlap the top margin of the fixed back section 35. A series of spaced openings 53 in the flange 52 will be closed in the overlapped position of the flange, but when the rear edge of the door portion is raised will permit ventilation through the openings from the interior of the hopper. As a result of the frictional engagement between the flange 52 and the top margin of the section 35,'the flange will be held in Ventilating position as indicated in broken outline in Fig. 4, when the door 45 is rst dropped toward closed position and until the flange is forced into the overlapping position thereof by pressing down upon the door.`

Cleaning of the interior of the case `is made easy by removing the top closure unit I3 and by opening the rear door 31,-or by removing the hopperv unit4 I froml the casing. Furthermore,

the interior surfaces which may require cleanw ing are. generally plane areas which are preferably of smooth nish whereby to facilitate the maintenance of an unsoiled and sanitary condition,

Where the exterior surfaces of the case are not formed of a material such as stainless steel which will keep anatural finish, they may be pleasingly finished by painting, enameling, or the like, or they may be suitably plated as with chromium and polished. In finishing by plating or vspray painting, the present construction is particularly advantageous and time saving because the body shell I0 and the back and top sections I2 and I3 maybe treated withoutmasking or other protective measures, for the only surfaces which it may not be desired to treat are contained in the hopper unit Il with which the other units are assembled after'treatment.

Having reference now to the modied form of the invention shown in Figs. 6 to 10, inclusive, it will be seen that the construction is fundamentally the same as just described. Therefore, in describing this modified form, the similarly constructed, generic elements of structure will, when necessary, be referred to only incidentally by the preceding numerals of reference. Notably, however, the modified ease has a rearwardly inclined front wall and a hooded top closure structure which embody novel features and will require a detailed description. As shown in Figs. 6, "I, and 10, the slanting front wall is formed in part by narrow right angular flanges 55 extending inwardly from the forward edges of the side walls I1 of the outer casing Vand lying in a common rearwardly inclinedplane. To complete the front wall, there is Secured `between the lower portions of the anges 55 and attached along its lower margins to the base I4, a horizontally elongated plate 51 which is of a width to extend in concealing relation above the front edge of the upwardly inclined portion 24 of the hopper bottom. The upper edge of the plate 51 and the inner edges of the flanges 55 define the outline of the window opening which is closed by the window pane 20 through which the interior of the case may be viewed by prospective purchasers.

Means may be provided on the front wall plate 51 for receiving and displaying price cards or the like. To this end the plate is provided with a horizontal series of apertures 58, one aperture for each hopper bin 26. Through these apertures may be viewed appropriate cards 59 supported by suitable flexible holders 60 which are secured to the inner wall of the plate 51. The necessary spacing between the plate 51 and the window pane 20 to accommodate the card holders 6D is effected by suitable inturned flanges 6I which are formed on the window framing edges of the front wall anges 55 and the plate 51 and bear inwardly against the outer face of the window pane. In addition to their function as spacers, the flanges 6I serve to provide a fairly snug joint between the window pane 20 and the front wall frame and to conceal the raw edgesof such frame. i

In order to illuminate the merchandise such as buttered, toasted nut meats behind the window pane 20, one or more electric lamps 62 may be mounted above and forwardly of the slanting front wall of the case so that the light rays from the lamp will pass downwardly and through the window. As shown in Fig. 1, the lamp 62 is carried in a socket 63 which is suitably mounted within and upon one wall of a forwardly projecting, downwardly opening hood 64. Herein this hood forms the front portion of the upper closure I3gt and extends across substantially the entire front of the case in such `a manner that the lamp 62 is concealed from direct view of a person standing in front of the display, but the full effect of the light and heat from the lamp are directed downwardly to illuminate and warm the nuts Within the case. As a result, the `heat will soften or liquefy the fat on the nut meats stored in the display pockets 29 and the light will cause the same to glisten attractively.

As illustrated (Figs. 6 and 7), the hood 64 has vertical side walls 65, a vertical front wall 61 disposed substantially` in a plane with the forward edge of the base I4, a narrow top wall 68 merging on a radius with the front wall 61, and a back wall 69 which slants angularly rearwardly and downwardly from the top wall 68 into overlying relation to substantial front portions of the hopper bins 26 which open up thereunder. The front, top and back walls of the hood may be formed of a single sheet of metal and secured to inturned connecting flanges 10 formed on the edges ofthe side walls 65. To support the hood, channel-shaped hanger bars 1I are secured to the side walls 65 and extend rearwardly therefrom to engage the top edges of the side wall I1 on the outer casing.

A translucent glass plate or other suitable sign 12 may be mounted within an opening 13 in the front wall 61 of the hood. The sign plate is supported by a lower inturned flange 14 upon the wall 61 and is held in place by suitable means such as bolted hanger brackets 15 (Fig. 9). Upon the back wall 68 of the hood is mounted an electric inlet socket 16 which is suitably connected with the lamp socket 63 by means of electric leads 11. The socket 16 is adapted to receive a detachable electric plug 18 carried by an electric current supply cable 19.

Hingedly connected tothe lower edge of the back wall 69 of the hood is the rear door portion 45 which forms a supplementary part of the main top closure and which may be opened as shown in broken outline to iill the hopper bins 26. When closed, the door 45 rests upon inturned flanges 80 form-ed upon the lower edges of the hanger bars 1I. This door serves'together with the back wall 69 to deect the heated air which rises to .the top of the case out through the open front portions of the hopper bins 26 which open into the Ihood 64, the path of the air being indicated in Fig. 7. Thus, the heated air will pass out from under the hood in front of the case, and the delectable aroma of the toasted nuts will pervade the surrounding atmosphere in a manner to serve as an additional inducement to prospective purchasers.

Preferably the top closure I3 of the modied form of `construction is mounted to be either entirely removed as a unit or to be opened for access to the front interior of the case by swinging the hood 64 upwardly as shown in broken outline in Fig. '1. For this purpose, the rear ends of the hanger bars 1IV are pivotally connected as by means of screw bolts 8l to the top `rear corners of the side Walls I1 in the outer cas-ing (Fig. 8).

To avoid the necessity of removing the bolts -8| when .it is desired to put the top kclosure I3EL imposition upon the case, or to remove the same .entirely away from the zcase, slots 82 are formed in the wall I1 to receive the Shanks of the bolts Y8| when the closure `is shifted with a sliding motion in a rear to front direction. Thus, in assembling the top closure I3a the hanger bars `1I arefirst fitted upon the runway provided by the top edges of the side wall I1, the rear ends vof the hanger overhang rearwardly as indicated in broken outline in Fig. 8. Thereupon, by sliding .the top closure forwardly the shanks of the `bolts BI will enter the slots 82, coming to a stop by rabutment with the walls defining the inner ends of the slots. By tightening the bolts 8I accidental dislodgment of the top closure may be substantially avoided, but the hood 64 may nevertheless be swung upwardly when it becomes necessary to gain temporary access to the front portions of the hopper bins 26 or change the lamp 62, or the like. In thus raising the hood, the door 45 will, of course, be tipped back with the closure unit, but will remain in its closing position to be raised independently to open position.

From the foregoing it will be apparent that the present invention provides a Case of unusually neat, eilicient and sturdy construction which is formed of intertting parts that are simple-to produce and which may be easily and quickly assembled or taken apart. Substantial quantities of several varieties of bulk goods may be attractively and appealingly displayed and eifectively conditioned for sale.
