The present disclosure relates, in general, to a method of fabrication coffee pods from a device to be located at a point of sale location. The device is capable of the individualized, personalized packaging of generally elutable or dissolvable materials such as coffee, tea, herbs, organics and the like. This disclosure incorporates by reference the entire disclosure of U.S. Utility patent application Ser. No. 15/005,528, filed Jan. 25, 2016.
The American populace loves their coffee. Most people begin their day with a cup of their favorite blend while others continue to partake throughout the day, commonly obtaining it from a their favorite “mom and pop” coffee roaster or a commercial vendor such as Starbucks®. However, of lately, many brew their own coffee using an individual brewing device such as a Keurig® brand coffee brewer. These allow for individual sized brewings using what have been come to be known as “k cups” or “coffee pods”.
Along with a populace that loves their coffee, come a segment of coffee aficionados. This breed of coffee drinker seeks specific coffee beans or coffee bean blends. The commercial coffee vendor market has rallied to meet this segment's demand, with most stores offering a plethora of coffee beans, however the selection of available coffee pods lags far behind. This is understandable, as to stock numerous blends of quantity boxed coffee pods takes up valuable store space. Thus, the coffee aficionado that relies on their individual brewing device has a rather limited selection.
This situation worsens when the coffee aficionado is at a location away from his individual brewing device or only has bulk brewing capabilities. Such an example would be rough woods camping. With the cost of these specialty beans as high as they are, no one wants to waste good coffee on the unappreciative or those with an undiscerning palate.
Another problem lies not with the coffee aficionado but rather with the small “mom and pop” coffee roasters. These entrepreneurs generally lack the equipment to pre package their coffees into pod format for their clients, and as such, loose this share of the market.
To date the commercially available coffee pods are made at a location remote from their point of sales and as such reflect a time lag between grinding and use. Further, these pods are prepared in common varieties by the larger coffee roasters. Often an aficionado of coffee has developed a taste for some of the more rare beans or even for a specific blend of beans. Neither of these are available in pod form. Complicating the issue, to make the pods affordable (since the price of commercially preparing these dramatically rises the cost of the coffee) they are packaged in large boxes, often in the 90 pod range. This, for many, takes months to go through and freshness becomes a taste issue.
Henceforth, a method of preparing small quantities of coffee pods that are blended to the consumer's taste from the bean or beans of their own selection, directly at the store or coffee roasters, would fulfill a long felt need in the coffee industry. This new method utilizes new technologies with newly developed devices in a unique and novel configuration.
In accordance with various embodiments, a method for fabricating small batches of personally selected or personally blended, freshly ground coffee in coffee pod format provided.
In one aspect, a method is provided that allows a consumer to fabricate small batches of coffee pods with their own elutable or dissolvable materials such as coffee, tea, herbs, organics, and flavorings (e.g. vanilla bean) and the like.
In yet another aspect, a method that allows the for the fabrication of coffee pods from a high speed, high volume, point of sale mechanized coffee pod distributing device that is capable of grinding, filing, sealing and packaging elutable or dissolvable materials is provided.
Various modifications and additions can be made to the steps of the method discussed without departing from the scope of the invention. For example, while the steps of the methods described above refer to a specific order, the scope of this method also includes different combinations of sequences of steps that fabricate the same coffee pod.
A further understanding of the nature and advantages of particular methodology embodiments may be realized by reference to the remaining portions of the specification and the drawings, in which like reference numerals are used to refer to similar components. In some instances, a sub-label is associated with a reference numeral to denote one of multiple similar components.

The operation and steps in the method of producing coffee pods from the coffee pod point of sale fabrication device 2 (
The coffee pod fabrication device 2 utilizes empty coffee pods from a linked, continuous-feed capable ribbon format 6 (
In the preferred embodiment of
It is to be noted that the upper lid 12 has an orifice 28 therein to accommodate both the means for pod expanding (air inflater) 52 and the means for coffee filling 80 so as to allow the expansion of the well 10 of the pod 4 and the insertion of ground coffee beans. The upper lid 12 will generally be made of a natural paper or cellulose fiber. The upper lid 12 will act as a stiffener and be of thick enough material and will have enough material existing about its planar surface to ensure that the coffee pod 4 does not collapse when it cap 22 is being pierced by a single serving coffee brewing machine.
The second embodiment coffee pod of
Looking at
It is to be noted that similar to the ribbon format, in the tape format each compressed pod is separably connected to its three or four adjacent compressed pods (the one in front, the one behind, and the one on the left or right side, or the two on both the left and right sides) by a connection tab 18 with a means for separation 20 disposed thereon. Alternate embodiments of the means for separation, as discussed above, may be utilized and more than one embodiment of means for separation may be used on the conjoined pods in a tape format.
There is a plethora of other embodiments which the means for separation 20 could take. It could be a line of flexible mastic joining two short tabs that abut each other, it could be a releasable, flexible, adhesive strip spanning and affixed to two short tabs extending from each coffee pod top, it could be a frangible strip residing between two short tabs extending from the coffee pod top, or the like. In an other embodiment of the means to separate, the filter media used to form the fillable well could be made from a roll of filter media extended beyond the well to conjoin adjacent coffee pods 4, possibly forming the wells on adjacent coffee pods. The coffee pods would then lack a tab but rather, would be conjoined in a linear fashion by the length of filter media that formed all of the wells. There could be notches or perforation lines on any of the aforementioned means to allow separation in the way described that occurs at the curved end of the linear conveyor belt 50. The primary criteria for selection would be the resilience to minor twisting or expansive forces below a critical level without allowing the release of adjacent pods. These forces and the angles at which they are applied to the pods will differ depending on which embodiment of the coffee pod point of sale fabrication device the linear array of pods is being used with.
In a further alternate embodiment of coffee pod design, the coffee pods may not be attached to adjacent pods but rather fabricated as individual pods. This format of presentation works best with the second alternate embodiment fabrication device using the rotary platter pod advancing means (
In the way of a general overview, (
The mechanization of the features presented by the pod advancing means 50, means for pod expanding 52, coffee filling means, sealing means 66 and ejection station 68 (and optionally the cleaning means 64 and bagging station 76) are well known by one skilled in the art and involve rotary and or linear motors, compressors, and position and level sensors. They will not be described in detail herein. Their integrated operation is sequentially controlled by the operational system 72 which is in operative communication with these devices as is well known in the art.
This device 2 allows a user to fill a series of coffee pods 4 with their choice of a particular ground coffee bean or a blend thereof. These pods will be operationally compatible with most of the popular, commercially available, individual cup coffee brewing machines.
Looking at the broad conceptual drawing of
The expansion of the compressed coffee pod 4 into the expanded coffee pod is accomplished by an air expander that provides a burst of air past the upper lid orifice 28 and into the well 10 to inflateably expand the well into its concave configuration. In an alternate embodiment, a linear actuator connected to a mechanical rod may extend beyond the lid orifice 28 to contact the well 10 to mechanically urge or expand the well 10 to its full extent, or a vacuum may be applied to the underside of the compressed pod as shown in
Looking at the manner of separation of the expanded, filled sealed coffee pods in the preferred embodiment, it can be seen that as the pods 4 reach the curved end of the track 82 the leading pod in the conjoined linear array drops from the planar path it traversed to be expanded, filled and sealed, and follows the oval path of the track 82. In doing so, two effects are put into motion. First, the tab 18 hinges about its approximate midpoint which is where the means for separation 20 resides. Second, the distance between the lids of the adjacent filled coffee pods increases. Each of these effects put stress on the means for separation 20 causing the perforations to tear and the adjacent pods to separate. With the belt inverting, the pods are ejected from the belt orifices 86 so that they may fall by gravity into a chute directed towards the portal or first to the optional bagging station 76.
Although the device 2 is described herein with the separation of the individual pods 4 from the ribbon array occurring at the ejection station 58 it is known that in other embodiments this separation could occur at the front end of the pod advancing means with the pods continuing along, their wells in the belt orifice 86 as they proceed through the expansion, filling, sealing and ejection.
The preferred embodiment of the pod advancing means utilizes a conveyor belt that moves the array of pods along a linear path within the device 2. As can be seen in
As can be seen the preferred embodiments of
With respect to some of the finer details of operation, in one embodiment the means for coffee filling 80 comprises a coffee bean hopper 54, a grinder 56, a doser 58 and a fill nozzle 60. (
The feeding of adhesive seal 22 is driven by motors. Since the number of revolutions of the advancing spool 99 changes with the diameter of the seal roll 100 a magnetic pickup 102 and sensor arrangement, as is well known in the art, is keyed to the spool. This provides electronic feedback to the processor that algorithmically drives the spool so that the seals always matingly conform to properly seal the coffee pod upper lid 12.
The operational system 72 generates the specific operational signals based on user defined instructions and consumer input into the tactile input module 71. It is composed of a tactile input module 71, a billing module 73, a collection module 75 and an operational module 77. Generally, the device employs a processor or any device or combination of devices, that can operate to execute instructions to perform functions as described herein. Merely by way of example, and without limitation, any microprocessor can be used as a processor, including without limitation one or more complex instruction set computing (CISC) microprocessors, such as the single core and multicore processors available from Intel Corporation™ and others, such as Intel's X86 platform, including, e.g., the Pentium™, Core™ and Xeon™ lines of processors. Additionally and/or alternatively, reduced instruction set computing (RISC) microprocessors, such as the IBM Power™ line of processors, processors employing chip designs by ARM Holdings™ and others can be used in many embodiments. In further embodiments, a processor might be a microcontroller, embedded processor, embedded system, system on a chip (SoC) or the like.
There are two embodiments of the method of manufacturing coffee pods. The first is by an attendant and the second is by the consumer.
The first, preferred embodiment of the method of fabrication coffee pods is performed by an attendant at a distributor of coffee beans. The attendant would oversee the fabrication stream (all the steps listed), controlling both the quantity of the pods produced and the blend of coffee beans used as well as replenish the inventory of consumables used by the device (such as the pods, labels, coffee, bags etc.) and remove the accumulated trash (such as paper carrier for seals, coffee grinds etc.). The method would be performed on a coffee pod fabricating device (the device) with a single coffee filling means. It has the following steps:
Determining of the desired coffee beans (blended or otherwise) and the number of coffee pods desired to be fabricated;
Filling the hopper of the coffee filling means of the device with the desired coffee beans;
Driving the pods advancing means so as to draw the compressed coffee pod linear array from the pod feed station into their operational location on the pod advancing means belt (situating the top flange of the coffee pod to the location stops such that the filter well resides over the orifice in the belt);
Advancing the pod linear array to the pod well expansion means;
Expanding the filter well of the first pod in the linear array (until it extends below the orifice in the belt where the pod was indexed, to receive a volume of ground coffee);
Advancing the expanded pod until it resides operationally adjacent the coffee filling means;
Grinding the coffee beans in the hopper;
Delivering a quantity of ground coffee beans into the pod well;
Advancing the filled coffee pod through a cleaning station removing any debris from the top planar face of the pod (preparing it for sealing)
Advancing the filled pod to a sealing station;
Adhesively a seal onto the top planar face of the pod's lid, covering the filled well;
Advancing the sealed coffee to an ejection station;
Detaching the sealed pod from its adjacent pods;
Ejecting the sealed pod from the pod advancing means.
With the ribbon or tape style of conjoined pods, the trailing adjacent pods would also follow this same process so as to constitute a continual disbursement of pods. The selected number of pods will fall into a chute for disbursement to the consumer. A counting station monitors the number of pods generated and stops the device when the appropriate number is reached. The belt of the pod advancing means would continue advancing, empty, until it reached the pod feed station and another compressed coffee pod was seated into its indexed position.
There are additional steps to be performed prior to the fabrication of coffee pods by the device. These steps are:
Installing an adequate supply of coffee pods and seals in the device; and
Correctly locating the linear array of coffee pods onto the pod advancing means. (It is to be noted that correctly locating the linear array of coffee pods onto the conveyor belt using the preferred embodiment of the device is accomplished by alignment of the coffee pod's top flange periphery against the locating stop. This locates the filter wells of the pod directly atop the belt orifices in one of the panels and allows the pod array to be fed/dragged forward with the belt by the locating stop.)
The second, (alternate) embodiment of the method of manufacturing coffee pods is performed by the consumer using the device installed at a local store. The consumer would merely select both the quantity of the pods produced and the blend of coffee beans used. The method may be performed on a coffee pod fabricating device (the device) with a single coffee filling means however it is likely that the consumer operated version of the device would incorporate multiple coffee filling means. It has the following steps:
Determining the desired coffee beans (blended or otherwise) and the number of coffee pods desired to be fabricated and inputting this number into the tactile control panel;
Paying the cost presented in the video display interface of the tactile control panel;
Filling the hopper of the coffee filling means of the device with the desired coffee beans or optionally selecting the beans provided in the multiple hoppers of the coffee filling means;
Driving the pods advancing means so as to draw the compressed coffee pod linear array from the pod feed station into their operational location on the pod advancing means belt (situating the top flange of the coffee pod to the location stops such that the filter well resides over the orifice in the belt);
Advancing the pod linear array to the pod well expansion means;
Expanding the filter well of the first pod in the linear array (until it extends below the orifice in the belt where the pod was indexed, to receive a volume of ground coffee);
Advancing the expanded pod until it resides operationally adjacent the coffee filling means;
Grinding the coffee beans in the hopper;
Delivering a quantity of ground coffee beans into the pod well;
Advancing the filled coffee pod through a cleaning station removing any debris from the top planar face of the pod (preparing it for sealing)
Advancing the filled pod to a sealing station;
Adhesively placing a seal onto the top planar face of the pod's lid, covering the filled well;
Advancing the sealed coffee to an ejection station;
Detaching the sealed pod from its adjacent pods;
Ejecting the sealed pod from the pod advancing means.
Operationally, the consumer would initiate the operation of the fabrication stream by engaging the device's computerized control panel and using a tactile input module to select the quantity of pods, (by number of pods of weight/volume of coffee beans to be dispensed) the hopper or hoppers to be used for filling the pods. Some hoppers are filled with different selections of coffee beans and optionally, some hoppers may be vacant. If the consumer wants pods filled with their own coffee bean, and there is such an optional empty hopper, they would add their bean to the empty hopper. The billing module would calculate the cost and indicate this to the consumer on a video display interface. The consumer would pay the indicated cost electronically or with physical money to the appropriate collection module on the control panel, which upon verification of receipt of the full cost billed, would initiate the operational module to begin the pod filling process. This follows the same operational procedure as outlined above with the exception of the selective operation of one of the multiple coffee filling means. Optionally, there may be a delivery station used to collect all the filled, sealed pods in that consumer's order into one sealable container prior to delivery to the consumer. This may be done either automated or manually. The belt would continue advancing, empty, until it reached the pod feed station and another compressed coffee pod was seated into its indexed position.
As can be seen from the above disclosure, a linear series of successively linked compressible, shell less coffee pods having a means for separating coffee pods located on its hingeable connection tabs, allows for a method of rapid commercial filling of individual coffee pods. In its simplest methodology the coffee pod filling device would fill compressible coffee pods with the following steps:
A method of fabricating coffee pods from a coffee pod fabricating device comprising the following steps:
Optionally there would be a step removing any debris from the top planar face of the lid of the pod prior to sealing the filter well.
The steps described according to a particular methodology may be organized in alternative orders. Hence, while various embodiments are described with—or without—certain steps for ease of description and to illustrate exemplary aspects of those methods, the various steps described herein with respect to a particular method can be substituted, added, and/or subtracted from among other described steps unless the context dictates otherwise.
Consequently, although several exemplary method embodiments are described above, it will be appreciated that the methodology is intended to cover all modifications and equivalents within the scope of the following claims.
The following application is a continuation in part of U.S. patent application Ser. No. 15/005,528 entitled “Coffee Pod for Point of Sale Device” filed Jan. 25, 2016, and incorporates by reference all the material therein.
