BACKGROUND OF THE INVENTION
1. The Field of the Invention
The present invention relates to a device for storing and applying lids to cups. More specifically, the present invention is directed to a device for storing and applying lids to beverage containers or cups.
2. Background Art
Restaurants, especially those catering to fast food and drinks have traditionally been focusing on improving packaging of food items and drinks so that the purchased food and drinks may be enjoyed at the restaurant and also taken out to be enjoyed elsewhere. A food and drink item meant to be a “take-out” item must be properly packaged and contained properly. Efforts in reducing costs for providing these convenience items have resulted in food and drink packaging that will only survive a short duration upon the commencement of their use. Traditionally, either a disposable plastic or paper cup is provided to receive beverages of a consumer's choice before the cup is sealed with a lid. Stacks of lids are typically provided at a self-serve restaurant so that patrons can access them and pick out appropriately-sized lids for their cups. In doing so, a messy, unsanitary and wasteful condition can be created. First, lids of various sizes may be provided for cups of different sizes. When presented with lids for various sized cups, a patron tends to simply pick up a lid before determining whether the lid that has been picked up is meant for the cup in hand. If the lid is unsuitable, then the patron may proceed to return the wrong lid to the same stack after exposing the lid to the patron's hand, soiled cup or other countertop surfaces. The next patron may find the wrong lid soiled and proceed to discard it. Further, the use of an incorrectly-sized lid may cause spills as the patron may try to fit the lid over a cup that is either too big or too small. Further, a patron may apply excessive force in an attempt to ensure that a lid has been properly applied, causing the cup to collapse and spilling the contents of the cup. Inefficiencies caused in a drink serving area can leave an unsanitary condition and an unwelcoming scene in addition to lost profits due to wastes and the need to clean up the area. Yet further, in food service areas, e.g., service stations and small cafes, management of peripheral items, e.g., lids cannot be attended to at regular intervals due to staffing availability. Yet further, a patron may try to fit a correctly size lid but may not achieve a uniform seal on the cup lid when applied manually leading to a lid to cup bond that may leak on the patron. These environments must rely on a device to manage lid stock and lid application in order to maintain sanitary conditions. Other users that may face challenges seating lids and can benefit from a device that aid in seating lids include beverage servers. e.g., coffee baristas and servers of drive-through food services, etc.
There arises a need for a drink establishment that is hygienic where the beverage cups may be sealed using a sanitary and reliable method without requiring a tremendous capital investment. Disclosed herein is a container lid application device configured to solve the problems disclosed elsewhere herein.

PARTICULAR ADVANTAGES OF THE INVENTION
Advantages of the present invention include, but are not limited to, eliminating the need for human contact with beverage lids during selection from lid storage and application to the container, complete engagement of the beverage lid with the beverage container, and the device is powered entirely by physical user input. The magazine of lids is enclosed within a shield of the device, which prevents human contact with unused lids. Each lid is transferred from a dispense assembly to a press assembly without human contact with unused lids. Each lid is directly applied to a beverage container by the press assembly, which prevents human contact with the lid during application.
In one embodiment, the press assembly applies uniform force around the periphery of a lid such that it can be applied to the mouth of a cup, ensuring that lid engages the entire perimeter of the cup opening, preventing lid failure as well as beverage leakage or spillage. In each pressing action, the press assembly of the present device enables a consistent pressing force to be applied to the lid in order to seat the lid to close the mouth of a cup, allowing a proper closure without undue force that can crush the cup. Excessive downward force applied to a cup is deflected by a mechanism that allows the handle used for moving the press assembly to the cup to bend, thereby diminishing the user's capability in further applying downward force to the press assembly which can crush the cup.
A user of a present device is not concerned with the steps required to seat a lid atop a cup. A self-explanatory linear action is all that is required to dispense a lid from a magazine of lids, bring the lid to a cup and to seat the lid so as to close the mouth of a cup. The present device can consistently dispense a lid from a magazine of lids and seat the lid all in a single slide action.
In one embodiment, the present device is powered by a human force without input from electric, pneumatic, hydraulic, or other power sources, allowing placement of the device to be independent of new or existing power sources and therefore can be set up on any surfaces accessible and convenient to users.
The present device is configured to receive a magazine of lids and dispenses one lid at a time for each linear slide action, making the action to seat a lid to close the mouth of a beverage container or cup uncomplicated. Further, upon seating a lid, no effort is required of the part of a user to return to the device to a position such that the next lid seating action can be carried out again as the press assembly of the device is automatically returned to be replenished with the next lid once the press assembly has been released by a user.
The present device is capable of achieving a lid application cycle time that is less than hand application cycle time with complete sealing of the mouth of a cup.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
The term “about” is used herein to mean approximately, roughly, around, or in the region of. When the term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth. In general, the term “about” is used herein to modify a numerical value above and below the stated value by a variance of 20 percent up or down (higher or lower).
FIG. 1 is a conventional setting of a beverage fulfilment center at a self-serve restaurant, depicting a condition where beverages may be spilled and beverage containers or lids are strewn about and wasted. A typical workflow at such a center involves a user choosing a cup 20 of a particular size. Then the user chooses a beverage and places the cup at a station to receive the beverage. The user then locates a spot in front of a tray where an assortment of condiments are disposed in order to regroup. Magazines 24 of lids are exposed, leaving them at the mercy of dust, germs, and other people's hands. Further, the countertop space can be limited. An uncluttered countertop is essential for the final preparation of beverage. Often times, patrons pick up more lids 22 than required, creating wastes and clutter. If a lid 22 is not properly made around the lid of the cup, it can lead to spills, stains and burns.
FIG. 2 is a present setting of a beverage fulfilment center at a self-serve restaurant, depicting the use of two disposable beverage lid storage and application devices at a self-serve restaurant. Magazines 24 of lids are kept safe and clean within the housing of the present device. A lid application device is provided to create a nearly perfect seal around the mouth of a cup, preventing spills and speeding up the process of seating a lid on a cup. A designated station as one shown herein improves an establishment's image and cuts down on clutter. Lids are applied one at a time to ensure that waste is kept to a minimum. The ensuing figures disclose a disposable beverage lid storage and application device capable of aiding a user in consistently seating a lid on a cup. The user first fills a cup with a beverage, e.g., soda, water, hot water mixed with hot cocoa or coffee products, hot cocoa, coffee, solid food products, etc., prior to arriving at the device. Alternatively, the cup may be filled with a content while being seated at the device, e.g., by pouring the content directly into the cup while it is seated in the present device. FIGS. 3-7 depict the outer appearance of the present device and its various components at a superficial level. FIGS. 8-30 delves into the details of the various components of the device.
FIG. 3 is a top front perspective view of a disposable beverage lid storage and application device in its at-rest condition. The device is generally a housing 62 or structure to which a number of assemblies are attached. A magazine of lids is fed within a magazine shield 60 before arriving at dispense assembly 4 which receives the magazine of lids and dispenses it to the press assembly 6 which can be moved along guide 28 before a lid received in the press assembly can be seated over the mouth of a cup disposed within a cup holder 14 at a first position at the bottom of the device. The magazine shield 60 prevents an unauthorized person to tamper with the lids disposed therein. A plurality of retainer springs 16 are disposed about the cup holder 14 for snugly receiving a cup and centering the cup while it is seated in the holder 14 in anticipation of the application of a lid atop the cup. FIG. 4 is a top front perspective view of a disposable beverage lid storage and application device, depicting a press assembly 6 of the device being coupled to a dispense assembly 4 of the device in preparation for receiving a lid, transporting the lid and pressing it onto a beverage cup 20. Here, a cup 20 is shown seated in the cup holder 14, ready to receive a lid that will be loaded in the press assembly 6 once the press assembly 6 starts being pulled down at the handle 18 onto the cup 20.
FIG. 5 is a top front perspective view of a disposable beverage lid storage and application device, depicting a press assembly having grasped a dispensed lid 22, starts to be transported downwardly while the lid 22 is being rotated in preparation for being pressed or seated onto a beverage cup 20. Rotation of the dispensed lid 22 is necessary as the magazine is loaded with the lids disposed in an upside down fashion.
FIG. 6 is a top front perspective view of a disposable beverage lid storage and application device, depicting a dispensed lid 22, having been transported to the cup 20 from the dispense assembly 4 by a transport assembly 8 and is being pressed onto a cup 20. Note that only one bushing 26 is visible in FIG. 5. Although two guide-bushing pairs are used, a single guide-bushing pair may be sufficient as long as the act of seating a lid on a cup involves only grasping a handle and pulling it downwardly in a linear fashion and that the one pair is sufficiently stiff to enable smooth operation of the device 2. FIG. 7 is a top front perspective view of a disposable beverage lid storage and application device, depicting a lid having been pressed onto a beverage cup and a force limiter, i.e., a resilient member 54, having been activated to avoid excessive force getting applied to the cup 20.
In summary, the present device includes a dispense assembly, a transport assembly, a rotator assembly, a press assembly that is connected to the rotator assembly and a force limiter assembly. In use, as the handle 18 is pulled away from its at-rest position towards a cup to be capped with a force, e.g., applied by hand or manually, a released bottommost lid of the magazine of lids, is received in the press assembly. The present device is configured for a magazine of lids that are loaded upside-down. The released bottommost lid is rotated by the rotator assembly while being transported by the transport assembly before arriving at the first position such that the released bottommost lid is securable to the beverage container by the press assembly. FIG. 5 depicts a device with a rotator assembly where the lid 22 is rotated to its eventual orientation of right side up as the handle 18 continues to be moved downwardly.
FIG. 8 is a top front partial perspective sectional view of the dispense assembly and press assembly of a disposable beverage lid storage and application device. A magazine 24 of lids is shown loaded in the dispense assembly 4 and supported essentially by the press assembly as the magazine support segments 32 are disposed in their retracted position. FIG. 9 is a top front partial perspective sectional view of the dispense assembly and press assembly of a disposable beverage lid storage and application device, depicting the press assembly 6 being lowered to separate the bottommost lid 22 from the rest of the lids of the magazine 24. FIG. 10 is a transparent view of the dispense assembly of a disposable beverage lid storage and application device. FIGS. 11-18 is a series of figures used for describing the manner in which the dispense assembly functions for a dispense assembly configured to accept a magazine of upside down or inverted lids. FIGS. 11-14 depict a series of actions that occur when the press assembly is returned to be coupled with the dispense assembly by the transport assembly. FIGS. 15-18 depict a series of actions that occur when the press assembly is being decoupled from the dispense assembly, e.g., when a lid seating is desired. The dispense assembly 4 is configured for indexing the bottommost lid from a magazine 24 of lids 22 in a first orientation, e.g., upside down. Referring to FIGS. 11-18, the dispense assembly 4 includes at least two magazine support segments 32 biased toward one another forming an opening 50, each of the at least two magazine support segments 32 is coupled to a plunger 36 at a top end of the plunger 36 such that when the plungers 36 are urged upwardly, the opening 50 is widened to release the bottommost lid 22 of the magazine 24 of lids before the opening 50 contracts to support the other lids of the magazine 24 of lids. FIG. 11 is a front partial sectional view of the dispense assembly showing a retained magazine 24 of beverage cup lids and a press assembly being returned, by a return spring (see part 66 of FIGS. 26-29) to be coupled to the dispense assembly to begin a lid seating sequence. It shall be noted that a ring member 42 of the press assembly is approaching a lower portion of the dispense assembly 4. Four sets of plunger (36)-magazine support segment (32) combination are radially disposed about an opening formed of the magazine support segments 32, although two opposingly disposed sets will suffice. Each plunger 36 is confined within an elongated cavity having a width and configured to be slideable vertically within the cavity. When inserted in a slot 34 of a magazine support segment 32, the position of each plunger 36 within the cavity dictates the size of the opening 50 formed of the magazine support segments 32 as a cutout 38 along the length of the plunger 36 enables a lateral shift in the magazine support segment 32. The plunger 36 has a width that is just under the width of the cavity allowing it to slide well within the cavity and a cutout 38. If a cylindrically-shaped cutout plunger 36 is used, the cutout 38 can be formed by routing out a portion of the plunger 36 while axially rotating the plunger 36. The plunger 36 can also be from of a rod of another cross-sectional shape as long as the cutout conforms to a particular profile. It shall be noted that the cutout 38 on the side of the opening is unnecessary although manufacturing techniques used in forming a cylindrically-shaped plunger 36 necessarily creates a cutout on the side of the opening. The cutout on the far side of the opening is required. A cutout that functions well is one which allows the plunger 36 to only have a limited range of movement and one which causes the plunger 36 to be retained within the cavity. A cutout that functions well has a surface that is roughly perpendicular to the direction of movement of the plunger 36 at its upper portion or a surface which limits the protrusion of the plunger 36 from the cavity and a surface that gradually approaches the width of the plunger 36 at its lower portion, causing an upward movement of the plunger 36 that drives an enlargement of the opening 50 of the segments 32 and a downward movement of the plunger 36 that drives a decrease in the opening 50 of the segments 32. When the press assembly is absent, spring 40 urges plunger 36 to protrude from the lower portion of the dispense assembly 4. Each segment 32 is normally urged towards the center of the opening by a spring 10.
FIG. 12 depicts the press assembly moving up and coming in contact with the plunger 36 of the dispense assembly, pushing the lid magazine support segments 32 outwardly to commence release of the bottommost beverage cup lid from the magazine 24. FIG. 13 depicts the press assembly continuing to move up and further elevating the plungers 36 of the dispense assembly, continuing to push the lid magazine support segments 32 outwardly. FIG. 14 depicts the release of the magazine 24 of lids as the press assembly has now fully depressed the plungers 36. FIG. 15 depicts the result of moving the press assembly away from the dispense assembly after they have been previously coupled. FIG. 16 depicts the press assembly continues to be moved down and further allowing the plungers 36 of the dispense assembly to drop, continuing to allow the lid magazine support segments to be biased inwardly to secure the magazine of lids with the exception of the bottommost lid. FIG. 17 depicts the press assembly continues to be moved down and clears the plungers 36 of the dispense assembly and the bottommost lid 22 is now separated from the magazine 24 of lids. FIG. 18 depicts a retained magazine 24 of beverage cup lids and the press assembly being returned to be coupled to the dispense assembly to be ready for the next lid seating sequence. Note that there are now three lids in the magazine 24, i.e., one fewer than the magazine 24 shown in FIG. 16.
FIG. 19 is a partial front perspective sectional view of a press assembly, depicting the manner in which a dispensed lid is being righted by a rotator assembly 64. FIG. 20 is a partial front perspective sectional view of a press assembly, depicting the manner in which a dispensed lid is being righted with some transport components removed. FIG. 21 is a partial front perspective sectional view of a press assembly, depicting a dispensed lid that has been righted. Upon leaving the dispense assembly, the transport assembly guides the press assembly to the cup onto which the lid 22 secured in the press assembly will be seated. The press assembly 6 is attached to a pair of bushings 26 disposed about the press assembly 6, each configured to slide along a guide 28. The guide 28 aids in guiding the lid grasping ring 30 to the cup or container at a first position in a first direction and guiding the return of the lid grasping ring 30 to the dispense assembly once seating of the lid secured by the ring 30 has been completed. A return spring (see FIG. 26) attached to the bushing 26, returns the press assembly to a second position in a second direction opposite to the first direction. A magazine 24 of lids is loaded with the lids upside down. As such, upon loading onto the press assembly, the bottommost lid must be righted before being seated to a cup. In this embodiment, the device further includes a rotator assembly. The rotator assembly includes a pair of pins 44 mounted about the press assembly in order to rotate the grasping ring 30, a rack 48 and a pinion 46 connected to a pin 44 on one end. The pinion 46 is configured to be rotatable about the central axis of the pin and a rack rotatably coupled with the rack 48. The rack 48 is part of a bar connecting the dispense assembly and a base. The rotator assembly is configured for rotating the lid grasping ring 30 to a second orientation that is disposed at about 180 degrees with respect to the first orientation. Further disclosed is a mechanism for stabilizing the lid grasping ring 30 upon rotation. A first pair of magnets 52, each magnet disposed in one edge of the lid grasping ring 30 in a plane in which the lid grasping ring 30 is disposed. A second pair of magnets 52 is disposed in the support ring 68, each magnet is disposed in a manner to match a magnet of the first pair of magnets 52 disposed in the lid grasping ring 30. Each magnet of the first pair of magnets is configured to be attracted to a magnet of the second pair of magnets, thereby aligning said first plane with a cup to ease seating of the lid onto the cup.
FIG. 22 is a partial side sectional view of a righted lid that is ready to be seated onto a cup. As the lid 22 continues to be lowered, the sealing rim 56 of the lid 22 eventually comes in contact with the cup lip 58. FIG. 23 is a partial side sectional view of a righted lid that has been seated onto a cup. The handle 18 is pivotably attached to the support ring 68. A force limiter 54 assembly is configured for bridging the handle 18 and the support ring 68. The force limiter includes a resilient member having two ends, a first end of the resilient member is attached to the handle 18 and a second end of the resilient member is attached to the support ring 68. As the lid 22 continues to be lowered further and when the applied downward force exceeds a pre-determined threshold, the handle 18 starts to get rotated, indicating that the lid 22 is now fully seated. As the handle 18 continues to rotate about the force limiter 54, the full extent of the downwardly applied force is avoided at the cup 20, thereby preventing the cup 20 from getting damaged. In one embodiment, the resilient member is a torsion spring. Alternatively, a flexible rod or a coil spring arranged coaxially with the handle may be used in place of the torsion spring.
FIG. 24 is a partial side sectional view of one embodiment of a press assembly. FIG. 25 is a partial side sectional view of another embodiment of a press assembly. Note the two different types of lids that can be used with the present device. In FIG. 24, the lid shown is a lid with its center extending above the sealing rim 56. The ring member 42 comes in contact with a portion of the center of the lid 22. In FIG. 25, the lid shown does not have a center which extends above the sealing rim 56. The ring member 42 comes in contact with a portion of the sealing rim 56 itself. A ring member 42 is preferably a resilient material, e.g., rubber and configured to be replaceable due to wear from repeated engagements and disengagements of lids. In one embodiment, the ring member 42 is a continuous structure. In another embodiment, the ring member 42 is a segmented structure. It shall be noted that the press assembly of shown in FIG. 25 further includes a protruding ring 12 disposed in a plane. The protruding ring 12 has an opening of a diameter that is smaller than the diameter of the opening of the ring member 42. The protruding ring 12 is disposed in a plane that is parallel to and at an offset to a plane of the lid grasping ring 30, where the protruding ring 12 comes in contact with a portion of the lid 22 such that the force can be uniformly applied on the lid 22 to secure the lid 22 to the lip 58 of the beverage container 20.
FIG. 26 is a partial side view of one embodiment of a lid application device, depicting a return spring 66 connected to a press assembly that is ready to return the press assembly to be coupled with a dispense assembly once the handle 18 is released.
