According to an exemplary embodiment, a multi-functional cover is used with a dispensing machine (e.g., a frozen yogurt dispensing machine, etc.) to assist, sort, track, and/or organize the disassembly, cleaning, and assembly of the dispensing machine. The cover is configured to extend across (e.g., fit over, cover, etc.) a hopper opening or cavity that provides access to the interior of a hopper for the dispensing machine. When placed in position over the hopper opening, the cover has an interior side (e.g., a side facing the inside of the dispensing machine, etc.) and an exterior side (e.g., a side facing the outside of the machine, the exterior environment, etc.). In one embodiment, the exterior side of the cover defines recesses that provide a handle or grip for lifting and handling the cover. In some embodiments, the exterior side of the cover includes legs extending therefrom such that the cover may stand on the legs when the exterior side is oriented downwards (e.g., the exterior side faces a surface such as a table or counter, etc.). According to an exemplary embodiment, the interior side of the cover defines various recesses shaped to receive various removable parts of the dispensing machine and/or tools used with the dispensing machine. Thus, when the cover is removed from the hopper opening and oriented with the interior side up, an individual part or tool may be removed from the dispensing machine and placed in the corresponding recess of the cover. The recesses may help to secure the parts in the cover. The recesses may also serve as a guide or indicator of which parts need to be removed and/or replaced and whether the disassembly or re-assembly is complete (e.g., provide an indication of which parts remain in the dispensing machine to be removed, to be reinstalled, etc.). After the dispensing machine is disassembled, the cover and parts may be taken to a cleaning area for cleaning. The cover thereby provides an organizational tool for use when cleaning, maintaining, and/or repairing the dispensing machine.

In other embodiments, at least one of the front rim portion 142, the rear rim portion 144, the left rim portion 146, and the right rim portion 148 have a different height (e.g., defining a notched shape in the rim 140, etc.) and/or a non-flat edge (e.g., wavy, dome-shaped, etc.). In alternative embodiments, at least one of the front rim portion 142, the rear rim portion 144, the left rim portion 146, and the right rim portion 148 are omitted.
As shown in FIGS. 4A-4D, the exterior surface 110 includes a first surface, shown as front surface 112, a second surface, shown as rear surface 114, a third surface, shown as left surface 116, and a fourth surface, shown as right surface 118. According to the exemplary embodiment shown in FIGS. 4A-4D, the front surface 112, the rear surface 114, the left surface 116, and the right surface 118 extend linearly at angle from the handle portion 120 to the front edge 132, the rear edge 134, the left edge 136, and the right edge 138 of the peripheral edge 130, respectively (e.g., the handle portion 120 is offset relative to the peripheral edge 130, etc.). The angled configuration of the front surface 112, the rear surface 114, the left surface 116, and/or the right surface 118 provides a run-off capability of the hopper cover 100 (e.g., for condensation, spilt mixture, etc.). In other embodiments, at least one of the front surface 112, the rear surface 114, the left surface 116, and the right surface 118 are flat (e.g., the handle portion 120 is coplanar or aligned with the peripheral edge 130, etc.). In still other embodiments, at least one of the front surface 112, the rear surface 114, the left surface 116, and the right surface 118 extend non-linearly (e.g., curved, dome-shaped, etc.) from the handle portion 120 to the front edge 132, the rear edge 134, the left edge 136, and the right edge 138 of the peripheral edge 130, respectively.
As shown in FIGS. 4A-4D, the feet 150 extend from the exterior surface 110. According to the exemplary embodiment shown in FIGS. 4A-4D, the feet 150 are positioned at each corner of the exterior side 106 of the hopper cover 100. In other embodiments, the feet 150 form a single, continuous base or foot that extends around the peripheral edge 130.

In an alternative embodiment, the feet 150 are omitted.
As shown in FIGS. 4A-4D, the feet 150 include a first face, shown as bottom surface 152, a second face, shown as first interaction surface 154, a third face, shown as second interaction surface 156, and a fourth face, shown as rear surface 158. According to an exemplary embodiment, the bottom surface 152 of the feet 150 is flat and configured to rest upon a surface such as a counter, table, or the like. As shown in FIGS. 4A and 4C-4D, first interaction surface 154 and the rear surface 158 offset the bottom surface 152 from the exterior surface 110 and the second interaction surface 156. According to an exemplary embodiment, the hopper cover 100 may stand on the feet 150 when the exterior side 106 is oriented downwards (e.g., the exterior side 106 faces a surface such as a table or counter, the hopper cover 100 is in oriented in the disassembly orientation 104, etc.). The feet 150 may thereby elevate the exterior surface 110 of the hopper cover 100 above a surface when the bottom surfaces 152 of the feet 150 are resting upon the surface.
As shown in FIG. 3, the feet 150 are positioned about the exterior surface 110 of the hopper cover 100 to fit within the hopper cavity 16 when the hopper cover 100 is oriented in the disassembly orientation 104. According to an exemplary embodiment, the first interaction surfaces 154 of the feet 150 are shaped to correspond with the shape of the hopper wall 19. The first interaction surfaces 154 of the feet 150 may thereby be configured to abut the hopper wall 19 of the hopper cavity 16 when the feet 150 are disposed within the hopper cavity 16. According to an exemplary embodiment, the second interaction surfaces 156 of the feet 150 are configured to rest on the lip 18 of the hopper cavity 16 when the feet 150 are disposed within the hopper cavity 16. In some embodiments, at least one of the first interaction surface 154 and the second interaction surface 156 of the feet 150 are shaped to correspond with the lip 18 and/or the hopper wall 19 of the hopper cavity 16 of the dispensing machine 10.
As shown in FIGS. 4E-4G, the interior side 108 of the hopper cover 100 has a surface, shown as interior surface 160. As shown in FIGS. 4E and 4G, the rim 140 extends past the interior surface 160 of the interior side 108 such that the interior surface 160 is recessed relative to an edge (e.g., the outermost portion, etc.) of the rim 140. According to an exemplary embodiment, the rim 140 forms a wall extending around the periphery of the interior surface 160, defining a cavity therebetween, shown as recess 162. In some embodiments, the interior face of the wall of the rim 140 extends at an angle from the interior surface 160 (e.g., linearly, etc.). In some embodiments, the interior face of the wall of the rim 140 extends normal (i.e., perpendicular) to the interior surface 160. In some embodiments, the interior face of the wall of the rim 140 is curved or otherwise shaped (e.g., non-linear, etc.).
As shown in FIGS. 4E-4G, the interior surface 160 defines a plurality of recesses, shown as depressions 164-186. According to an exemplary embodiment, the depressions 164-186 are configured to receive a plurality of components of the dispensing machine 10. Each of the depressions 164-186 may corresponds with a specific component of the plurality of components of the dispensing machine 10. As shown in FIGS. 3 and 4G, the depressions 164-186 are shaped to receive a plurality of components of the dispensing system 30 and/or the auger assembly 40 of the dispensing machine 10 such that the plurality of components are disposed within the recess 162. More specifically, as shown in FIGS. 4E-4G, the depressions 164 are shaped to receive the flights 44; the depression 166 are shaped to receive the springs 46; the depression 168 is shaped to receive the front support 48; the depression 170 is shaped to receive the front bushing 50; the depression 172 is shaped to receive the auger O-ring 52; the depression 174 is shaped to receive the rear seal 54; the depressions 176 and the depressions 178 are shaped to receive one of the valves 56 and the corresponding valve O-rings 58, respectively; the depressions 180, the depression 182, and the depressions 184 are shaped to receive the center valve 60 and the corresponding valve O-ring 62 and valve O-rings 64, respectively; and the depression 186 is shaped to receive an O-ring, shown as front door seal 66. In some embodiments, the interior surface 160 defines more or fewer recesses or depressions to receive more components (e.g., the auger shaft 42, the front door 32, etc.) or fewer components of the dispensing machine 10. In an alternative embodiment, the interior surface 160 is flat (e.g., does not define the depressions 164-186, etc.).
According to an exemplary embodiment, recessing interior surface 160 prevents the mixture (e.g., frozen yogurt mixture on the removed components, etc.) that may drip from the components of the dispensing machine 10 from sliding off of the interior surface 160 during transport and/or cleaning. According to an exemplary embodiment, the interior surface 160 having individual depressions for each respective component provides a securing feature. For example, the depressions 164-186 may help to secure the components of the dispensing machine 10 within the recess 162 of the hopper cover 100 (e.g., prevent the components from sliding around, etc.). In another example, the depressions 164-186 may help evenly distribute the weight of the components across the hopper cover 100 such that the hopper cover 100 is easier to carry and handle while the components of the dispensing machine 10 are disposed within the depressions 164-186.
As shown in FIGS. 4E-4F, the interior surface 160 defines a plurality of indicia, shown as indicia 190, positioned near and/or within each of the depressions 164-186. According to an exemplary embodiment, the indicia 190 include an identification number (e.g., part number, serial number, etc.) to identify the component that is received within the respective depression. Each of the indicia 190 may correspond with a specific component of the plurality of components of the dispensing machine 10. According to an exemplary embodiment, the interior surface 160 having individual depressions and/or indicia for each respective component provides a poka-yoke feature. For example, each of the depressions 164-186 structured to receive a specific component of the dispensing machine 10 and/or the indicia 190 may provide an indication of which components are currently removed and/or installed within the dispensing machine 10. This may help an operator both in assembly and disassembly of the dispensing machine 10. The hopper cover 100 may thereby provide an organizational tool for use when cleaning, maintaining, and/or repairing the dispensing machine 10. In another example, the indicia 190 may aid an operator in ordering damaged and/or worn components (e.g., aids in identifying the part number of the component for ordering purposes, etc.). In some embodiments, the hopper cover 100 may be provided with respective components of the dispensing machine 10 as a maintenance kit. For example, the maintenance kit may include the hopper cover 100 and various wear components (e.g., the front bushing 50, the O-rings 52, 58, 62, 64, and/or 66, etc.) to be used in periodic maintenance of the dispensing machine 10 (e.g., every six months, etc.).
According to the exemplary embodiment shown in FIGS. 5A-5B, a multi-functional cover, shown as hopper cover 200, is configured to be used with a dispensing machine (e.g., the dispensing machine 10, etc.) to assist, sort, track, and/or organize the disassembly, cleaning, and assembly of the dispensing machine. The structure and function of the hopper cover 200 may be similar to that of the hopper cover 100 described above in regards to FIGS. 1-4G. As shown in FIGS. 5A-5B, the hopper cover 200 includes a first side, shown as exterior side 206; an opposing second side, shown as interior side 208; and a plurality of legs, shown as feet 250. According to the exemplary embodiment, the hopper cover 200 is substantially rectangular in shape. In other embodiments, the hopper cover 200 is otherwise shaped (e.g., circular, oval, square, etc.). According to an exemplary embodiment, the hopper cover 200 is shaped to correspond with the shape of the hopper cavity 16, the hopper wall 19, and/or the lip 18 of the dispensing machine 10.
As shown in FIG. 5A, the exterior side 206 of the hopper cover 200 has a surface, shown as exterior surface 210. The exterior surface 210 defines a centrally located handle portion, shown as handle portion 220. In other embodiments, the handle portion 220 is otherwise positioned about the exterior surface 210 (e.g., along each lateral edge, along each longitudinal edge, etc.). As shown in FIG. 5A, the handle portion 220 includes a pair of recesses, shown as handle recesses 222, and a grip, shown as handle grip 224. According to an exemplary embodiment, the handle recesses 222 and the handle grip 224 cooperatively facilitate lifting and handling the hopper cover 200 from the exterior side 206.
As shown in FIG. 5A, the exterior side 206 of the hopper cover 200 includes an edge, shown as peripheral wall 230, that extends around the periphery of the hopper cover 200.
