The present development is directed toward the art of dispensers for cups and other cup-shaped articles (e.g., french fry containers, soufflé cups, ice-cream cones, etc.) and, more particularly, to a new and unobvious cup dispenser assembly. The term “cup” as used herein is intended to encompass cups and any other cup-shaped article suitable for being dispensed one-at-a-time from an interfitted or nested stack. Dispensers of the type under consideration herein are commonly employed in restaurants and convenience stores to maintain a supply of paper, plastic, foam, and/or other disposable cups and/or cup-shaped articles near beverage or soft-serve frozen food dispensing equipment for use as required, and cups are dispensed one at a time from the dispenser with the closed ends of the cups in the nested stack of cups oriented outwardly toward the user.
In accordance with the present development, a cup dispenser comprises a body defining a storage region adapted for receiving for an associated stack of cup-shaped articles. The body includes an open end that provides access to the storage region. A plurality of fingers are connected to the body for restricting the open end of the body. An adjustment ring is connected to the body and is movable relative to the body. Movement of the adjustment ring relative to the body alters a position of each of the fingers relative to the body.
An adjustable cup dispenser A constructed in accordance with the present invention is adapted for dispensing cups and other cup-shaped articles. As used herein, the term “cup dispenser” is intended to mean a dispenser for cups or other cup-shaped articles. In use, the cup dispenser A is mounted in a cabinet or other mounting structure B (
The dispenser A comprises an elongated cup storage tube or body 10 including an inner surface 12 that defines a hollow cup storage space/region 14 adapted to receive a telescopically interfitted or nested stack of cups to be dispensed one-at-a-time. The body 10 is illustrated in the preferred, substantially cylindrical and/or polygonal cross-section conformation, but those of ordinary skill in the art will recognize that the body 10 can be defined in any of a wide variety of other configurations so that it defines an elongated hollow cup storage region 14 adapted to receive and confine a nested stack of cups.
The body 10 and cup storage region 14 are defined about a central longitudinal axis L, and the body comprises an open first end 20 that opens into the cup storage region 14 and a closed or restricted or partially closed second end 22. The second end 22 is typically closed or at least restricted by an integral transverse end wall 24. The body 10 can be defined from metal or plastic or any other suitable material as desired.
In the illustrated embodiment, the body 10 includes a plurality of lugs or bosses 40 (
The cup dispenser assembly A further comprises an annular mounting collar 50 defined by a cylindrical portion 52 and a transverse flange 54 that projects radially outward from the cylindrical portion 52. The cylindrical portion 52 includes or defines a plurality of apertures or other recesses 56 (
The cup dispenser assembly A preferably comprises a spring or other means for biasing the stack of cups contained in the storage region 14 of the body 10 toward the open end 20 of the body 10 for being dispensed. In the illustrated embodiment, a coil spring 60 (
The cup dispenser A includes a plurality of fingers F connected to the body 10 and located adjacent the open first end 20 of the body to retain cups in the cup storage region 14 and control the dispensing of the cups one at a time. As shown herein, the fingers F also capture the pusher 62 in the cup storage space 14. A portion of each finger F extends inward from the body inner surface 12 toward the center of the cup storage region 14 so that the fingers restrict the open end 20 of the body 10. Each finger F includes a first or inner end F1 that is fixedly secured or connected to the body 10 at a location spaced from the open first end 20, a second or outer end F2 that is movably engaged with the flange 54 of the mounting collar 50 or that is otherwise movably located adjacent the open end 20 of the body 10, and a central ramped portion F3 located between the first and second ends F1,F2. The ramped portion F3 comprises a first ramp surface F3a that converges toward the center of the cup storage region 14 as it extends away from the open end 20 of the body 10 toward the opposite end 22 of the body, and includes a second ramp surface F3b, located between the first ramp surface and the inner end F1, that diverges away from the center of the cup storage region 14 as it extends away from the open end 20 of the body 10 toward the opposite end 22 of the body. The first and second ramp surfaces F3a,F3b intersect to define and are connected by a tip F3c of the ramped portion F3. The tip F3c is the most prominent portion of each finger F, in terms of the distance that the finger F projects into the cup storage space 14 from the inner wall surface 12 of the body 10. It is preferred that each finger F be defined as a one-piece construction from a polymeric resin such that the finger is resiliently flexible and the ramp portion F3 is resiliently movable toward and away from the inner surface 12 of the body when the first and second opposite ends F1,F2 of the finger are restrained against any movement relative to the body 10. The fingers F are circumferentially spaced-apart around the longitudinal axis L, preferably in a symmetrical arrangement as shown such that they provide a uniform and symmetrical gripping force on the cups or other cup-like articles being retained in the cup dispenser A.
As shown herein, the first end F1 of each finger F is connected to the body 10 by engagement of the first end F1 through a mating slot 70 defined in the body 10. The first end F1 of each finger includes a first or inner or mounting tab F1t that lies adjacent an outer surface of the body 10, and the first tab F1t prevents escape of the finger first end F1 from the slot 70 unless the finger is moved to a position where the first tab F1t is aligned with the slot 70, which cannot occur during normal use of the dispenser A.
Referring particularly now to
The adjustment ring 80 is defined from polymeric resin or metal and generally corresponds in size and shape to the flange 54 and is located adjacent an upper face of the flange 54 so as to overlie the flange 54. The flange 54 comprises at least two and preferably at least three mounting studs 55 that project outwardly therefrom, and the adjustment ring 80 comprises at least a corresponding number of elongated circumferentially extending mounting recesses or mounting slots 85 through which the mounting studs 55 respectively extend when the adjustment ring is positioned to lie adjacent the upper surface of the flange 54. The receipt of the mounting studs 55 through the mounting slots 85 serves to locate the adjustment ring 80 on the flange 54 and enables reciprocal circumferential movement of the adjustment ring 80 in a plane that lies parallel to the plane in which the mounting flange 54 lies. The extent of the elongated mounting slots 85 defines the limits of circumferential movement of the adjustment ring 80 relative to the flange 54 and mounting studs 55. After the adjustment ring is installed adjacent the flange 54, it is captured to the flange 54 so that it cannot move axially away from the flange. As shown herein, a keeper such as an enlarged head 86 is connected to each stud 55 by a screw or other fastener 57 engaged with the stud 55, and the adjustment ring 80 is axially captured between the enlarged head 86 and the flange 54, but with the adjustment ring still movable circumferentially relative to the flange 54. The enlarged head 86 can be provided as part of the fastener 57 or separate as shown.
The second tab F2t of each finger F or other part of the second end F2 of each finger F includes an adjustment stud FS that projects outwardly therefrom in direction extending transversely away from the collar flange 54, e.g., normal to the flange 54 as shown herein. The adjustment ring 80 includes at least a corresponding number of adjustment slots AS that respectively receive the finger adjustment studs FS and through which the finger adjustment studs FS extend. The adjustment slots are elongated and include a first or outer end AS1 located a first distance from the center of the cup storage space 14 (i.e., from the central longitudinal axis L) and include a second or inner end AS2 located a second distance from the center of the cup storage space 14 that is less than the first distance. As shown herein, the adjustment slots AS are identical to each other and each is arcuate or otherwise curved between the first and second ends AS1,AS2. The adjustment slots AS could be partly or completely linear between their first and second ends AS1,AS2. It is preferred that the adjustment slots AS be identical to each other to ensure that the fingers F will always be symmetrically located relative to the central axis L.
Referring to
Each adjustment slot AS thus defines a cam and each finger adjustment stud FS located therein defines a follower. Accordingly, the adjustment ring 80 comprises a plurality of adjustment cams AS and each of said fingers F comprises a follower portion FS engaged with one of said adjustment cams AS such that movement of said adjustment ring 80 relative to the 10 body induces inward or outward radial movement of the fingers F relative to the body 10, depending upon the direction in which the adjustment ring 80 is rotated relative to the body. Upon rotation of the adjustment ring 80, the fingers F move simultaneously and uniformly, which eliminates the need for a user to adjust and gauge the radial position of each finger independently.
The adjustment ring 80 rotates about the central longitudinal axis L and can be restrained in its desired angular position by any suitable means such as frictional interference with the flange 54 or parts thereof. As shown in
As noted above, the adjustment ring 80 includes access openings 88 that can be selectively registered with the mounting apertures 58 of the flange 54 to allow installation of the fasteners required to secure the flange 54 to an associated cabinet or other mounting structure B.
The dispenser A further comprises a decorative clamp ring or cover ring 90 that is selectively secured in covering relation over the adjustment ring 80 to conceal and protect same and to discourage tampering with same. Typically the cover ring 90 is defined from a polymeric resin material, but it could be metal. The cover ring 90 includes internal notches or undercuts 92 dimensioned and positioned to engage the respective enlarged heads 86 with a snap-fit or friction-fit when the clamp-ring 90 is operatively connected to the mounting collar 50 as shown in the enlarged “Detail 3A” portion of
The dispenser assembly A operates as will be understood by those of ordinary skill in the art. A telescopically interfitted or nested stack of cups is inserted into the cup storage space 14 via body open end 20 with resulting resilient deflection of the fingers F (optionally the adjustment ring 80 can be positioned to spread the fingers F to facilitate insertion of the stack of cups). The cup stack is pushed into the cup storage space 14 with sufficient force to overcome the biasing force of the spring 60 so that the cup pushing member 62 moves inwardly toward the closed second end 22 of the body 10. If required, before or after insertion of the cup stack, the cover ring 90 is removed and the position of the adjustment ring 80 is rotatably adjusted to set the desired position of the fingers F based upon the size and/or type of cups to be dispensed, and the cover ring 90 is then replaced. After the cup stack is loaded into the cup receiving region 14, the cup pushing member 62, in response to the biasing force of the spring 60, urges the cup stack outwardly toward the open first end 20 of the body 10 so that the closed end or bottom of the outermost cup in the stack projects out through the open first end 20 between the fingers F. To dispense a single cup, a user manually pulls the outermost exposed cup so that the fingers deflect resiliently outward sufficiently to allow only the outermost cup to be released. The finger tips F3c engage the next outermost cup in the stack and prevents it from exiting the cup storage space 14.
The development has been described with reference to preferred embodiments. It is not intended that the scope of the claims be limited to the preferred embodiments. Instead, it is intended that the claims be construed literally and/or according to the doctrine of equivalents as broadly as legally possible.
