DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
[0044] The following detailed description and disclosure illustrates by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the disclosed systems and methods, and describes several embodiments, adaptations, variations, alternatives and uses of the disclosed systems and methods. As various changes could be made in the above constructions without departing from the scope of the disclosures, it is intended that all matter contained in the description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
[0045] This disclosure is provided in the context of a fully automated, self-serve blender such as those described in U.S. patent application Ser. No. 17/195,080 and U.S. Pat. No. 10,245,571 and Ser. No. 11,207,646. The entire disclosure of all the above documents is herein incorporated by reference. This disclosure will, therefore, make reference to machine elements of a machine such as those contemplated in the above referenced documents. However, it would be recognized by one of ordinary skill in the art that the cup lid and cup contemplated herein may be used in any context where a lid which can be penetrated by a larger object than would fit through a traditional straw hole without damage is desired.
[0046] Self-service machines that utilize a blend-in-cup process so the drink is made within a (generally disposable) cup that is taken by the consumer after the blending process is complete eliminates the need to transfer the beverage to a cup after blending. Further, this type of arrangement also allows the raw material to be blended (for example frozen fruit) to be provided in an unblended but prepackaged and pre-partitioned state. With regards to the use of fruit in smoothies, this can result in a higher quality smoothie without causing a break-down of nutrients due to oxidation which typically happens in a standard blender.
[0047] Specifically, keeping the fruit in a sealed container until immediately prior to blending allows environmental control. Not mixing air in smoothies during the blend sequence and through oscillating blender blades at a low RPM also allows for improved quality to be maintained. Furthermore, by using an individual serving cup where the contents, once filled, are handled only by the end user, and with minimal food contact from the machine, the machine is able to minimize the amount of material wasted in each blending cycle, reduce cleaning requirements, and provide a safer food handling experience.
[0048] While this disclosure will utilize terms such as “above”, “below”, “forward”, “back”, “left” or “right” these terms are used as a matter of convenience to describe the typical arrangement of a device when interacted with by a human user and are not intended to imply an absolute direction relative to the Earth or other body. For example, while a first object which is “below” a second object will typically be closer to the earth than the second object in routine operation, this is not intended to be required as the devices herein could be oriented in any direction relative to the Earth or relative to any gravitational field (or without one, such as in deep space). Instead, these terms are used to show relative positioning of objects to each other. Thus if a third object was “above” the second object in the prior example, the three objects would typically be arranged generally linearly from the first object, to the second object, to the third object regardless of the various objects' positions in space. Similarly, an object on the right would be on a generally opposing side to an object on the left and movement forward would be in the generally opposing direction to movement backward.
[0049]
[0050] In the depicted embodiment, the lid (100) is in the form of a typical disposable cup lid having a generally circular cross section (corresponding to the top of the cup (200)) whose outer ring is designed to “snap” onto the upper rim of the cup (200). This is by the cup (200) including a raised lip extending outward from the rim to interact with the lid (100). The lid (100) typically attached by having an outer circumferential ring (101) including a detent (102) which extends inward toward the center of the lid (100) generally all the way around the circumference.
[0051] The detent (102) is displaced by the lip at the upper rim of the cup (200), typically by the detent (102) simply having a slightly deformable structure, and the detent (102) will return to position after it has cleared the lip. The lid (100) will, thus, be attached to the cup (200) by the resistance between the detent (102) and the lower portion of the lip. This is typically not a sufficient force to keep the two from separating at all, but will typically keep the lid (100) in place unless force is applied to deform the lip and/or detent (102).
[0052] In the depicted embodiment of
[0053] In the depicted embodiment, the upper base is in the form of a thin ring (106) as opposed to a flat solid surface, and includes within it a recessed disk (107). The disk (107), as can be best seen in
[0054] The center disk (107) also is typically not a flat solid surface, but includes a slightly raised rim (117) surrounding an orifice (301). The orifice (301) is partially closed by a plurality of flexible petals (303) which extend from the rim (117) toward the center of the disk (107) but leave open a central, generally circular, hole (305). The hole (305) is typically sized and shaped to have a suitable straw (315) placed therein as illustrated in
[0055] One of the purposes of the embodiment of lid (100) is that the structure of the lid (100) allows for keeping the lid (100) in place on the cup (200) during blending. Specifically, the petals (303) are designed to allow processing equipment, and particularly the blade assembly (501) to penetrate it and travel through as it slowly opens. This also allows the blade assembly (501) to retract smoothly after the processing. Blending in a cup (200) with a lid (100) in place where both are intended to be taken by the user as part of intended consumption, can significantly reduce the amount of service area of the machine in food contact. This can reduce the amount of the machine to be cleaned between blending operations, can minimize food waste, and can improve general user experience. The lid (100) also is sized and shaped and includes a variety of specific hills and valleys which interact with a counterpart component on the blending equipment. This allows for moving components on the blending equipment to be automatically centered on the cup (200), the cup (200) to be held in place and avoiding any spillage, and inhibit cup (200) movement during blending of material within the cup (200).
[0056]
[0057] During or after the descent of the blending bell (403), safety shields and other related systems (not shown) may be actuated to inhibit access to the cup (200) or lid (100) during blending. Once the blending bell (403) has descended and contacted the lid (100) the lid (100) and cup (200) combination is effectively pinched between the inner walls of the basin (401) from below and the blending bell (403) from above and the system is as shown in
[0058] In the position of
[0059] In another variation, the system can use a combination of the self-centering of the lid (100) design to push the cup (200) and lid (100) assembly in place via the blender bell (403) to ensure it is in the correct position and accommodate for any user error. A nozzle (not shown) in the blender bell (403) can be positioned precisely via a computer/sensor system to inject water through the lid while allowing air to escape to ensure no spilling and a precise of liquid is added to the cup (200) to ensure the correct quantity of water/liquid ratio.
[0060] Once the water is added to the material (551) in the cup (200), the blade assembly (501) will travel further down into the cup (200). Specifically, the blade assembly (501) will descend into and through the orifice (301). As shown in
[0061] In
[0062] Regardless of the number of petals (303) contacted, the petals (303) contacted by the blades (505) and/or assembly (501) will bend downward. They will also typically separate from each other increasing the gaps (333) between them. The blades (503) will typically slide along the petals' (303) upper surface as the assembly (501) descends. In
[0063] Once the blades (505) pass over the ends (313) of the petals (303) the petals (303) will return to their original unbent position. This is shown in
[0064] Regardless of the specifics of the size of the hole (305), it is generally preferred that the shaft (503) and hole (305) have similar diameter so as to produce a fairly close connection between the two. By having the inner edges (313) close to or in contact with the shaft (503), when the blades (505) are rotated, matter (551) inside the cup (200) which may be projected upward will typically hit the petals (303) or other part of the lid (100) and cannot easily escape the cup (200). This provides for less waste and also helps keep the cup (200), lid (100), and machine (and particularly the cavity (407) of the blending bell (403)) cleaner.
[0065] After the position of
[0066] In an embodiment, sensors and associated software or other control may be used to recognize the lid (100) and avoid any stalling of the blades (505) or blade assembly (501) when it is lowered into the cup through the lid (100). This can help improve reliability and durability of the entire system, ensure a consistent, premium user experience, and avoid any health and safety concerns should the lid (100) be deformed or incorrectly positioned in such a way that the blade cuts the petals (303) during the various movements.
[0067] In an embodiment, as the blades (505) present a large generally flat surface when descending, they may be expected to compress some material (551) under them as the blade assembly (501) descends. This will often increase as the blade assembly (501) gets lower in the cup as more material (551) is trapped and compressed. This increase in resistance can be used as a method to determine when the blade assembly (501) has descended the correct distance based on the composition of the material (551) in the cup (200).
[0068] Alternatively, the head (501) can descend essentially all the way into the cup (200) with the resistance of the cup (200) bottom being detected as different from the material (551) in the cup (200). The shaft may then be moved to position the blade assembly (501) at a specific distance from the bottom. This latter arrangement will typically be preferred as it allows the blades (505) to rotate at or near the bottom of the cup (200) which will typically produce a more uniform product as gravity and vortex action will help act to feed material into the blades (505). In yet another alternative embodiment, the distance of blade (505) descent may simply be controlled by an absolute or relative movement distance from the known starting position based on the type of cup (200) present or by any other means or method known to one of ordinary skill in the art.
[0069] With the blade assembly (501) properly positioned at the desired blending position, the blending takes place. In the blending position the petals (303) of the lid (100) are back in their generally horizontal position as contemplated above in
[0070] Once the blending operation is finished, the blade assembly (501) will retract vertically back to its original position with the blade assembly (501) in the cavity (407) of the blender bell (403). This requires the blade assembly (501) to again pass through the lid (100), but in the opposite direction. As the petals (303) have generally returned to their unbent position in
[0071] As can be seen in
[0072] To avoid any spillage beyond the food contact zone inside the cavity (407) of the blender bell (403) the blender bell (403) is generally pushed down by a spring or similar item onto the lid (100) while the blades (505) pass through the petals (303) as in
[0073] Once the blade assembly (501) has returned to the cavity (407) as in
[0074] In addition to providing for blender penetration through the orifice (305) as discussed above, the lid (100) can also serve to align the blade assembly (501) and shaft (503) in the center of the cup (200). This can be very helpful to inhibit the blades (505) from being able to potentially contact the side of the cup (200) as well as to best position the shaft (503) in the hole (305) to inhibit splashing of material from the cup (500) into the cavity (407) of the blending bell (403) during blending. As the cup (200) is also placed by a user and may include variations due to, for example, manufacturing tolerances, the cup (200) also may not be entirely straight in the basin (401) when the blending bell (403) descends.
[0075]
[0076] In the embodiment of
[0077] As can be seen in
[0078] Typically, the various engagements between the base (601) and the lid (100) shown in
[0079] This force and resultant friction will typically be sufficient to inhibit the lid (100) from rotating or otherwise moving during blending. Further, the cup (200) will typically be pushed into the basin (401) (and also tilted to be upright and solidly against the base (601)) by the action of the blending bell (403) pushing downward on the lid (100). Engagement of the cup (200) with the basin (401) will also typically be a frictional engagement so as to not damage the cup (200) or impair its appearance when it is removed. The frictional engagement between cup (200) and basin (401), along with the frictional engagement of the lid (100) to the cup (200) and the lid (100) to the blending bell (403) will inhibit both the cup (200) and lid (100) from rotating during blending and from moving relative to each other. In an embodiment as depicted in
[0080] In the event that the drink is particularly viscus, or where the above frictional connections are otherwise insufficient to inhibit rotation, an alternative embodiment of the lid (100) as shown in
[0081] Once the cup (200) is removed, the system may be cleaned. During cleaning, the blender mechanism will begin in its ready position as shown in
[0082] Depending on the embodiment, the blades (505) may be positioned within the cavity (407) or may be moved into cavity (421) for rinsing, cleaning, or sanitization. The latter lower position may be preferred to allow more of the shaft (403) to be within the joint cavity. Cleaning the shaft (503), however, will typically not be required as gasket (457) may be used to “wipe” the shaft (503) due to the presence of a high friction connection as the shaft (503) was retracted during
[0083] During cleaning, water (which may be from the same source as is used to supply water to the cup (200), or a different source) may first be used to rinse the inside cavity (407) of the blender bell (403), the cavity (421), the blade assembly (501), the blades (505), and/or the shaft (503). This rinsing may be followed by an automated cleaning cycle and, when required, a sanitization cycle. After a drying period (if required) for all cleaned and/or sanitized food contact areas, the blade assembly (501) will typically return to its position inside the blender bell (403) and the blending mechanism will return to the position of
[0084] In order to supply improved sanitation and safety and inhibit tampering with the material in the cup (100) prior to blending taking place, a removable seal (901) may be used to seal the orifice (301) in an embodiment. An embodiment of such a seal (901) is provided in
[0085] In an embodiment that includes a removable seal (901), such as that of
[0086] In a still further embodiment, a seal may be used which does not cover the petals (303) but acts to replace them. Specifically, the orifice (301) may be covered by a seal such as, but not limited to, a foil seal that the blade assembly (501) can ready pierce and push out of the way as it descends. Similarly, the grooves (317) may not be fully cut, but may comprise points of weakness where the petals (303) are designed to separate as the blade assembly (501) pushes on them. The hole (305) may similarly comprise a segment or segments which are designed to remain attached to a petal, but pend out of the way of the hole (305) in a temporary or even permanent fashion.
[0087] The hole (305) will preferably be covered or filled after the blending process to avoid spillage if consumers take the drink on-the-go. As contemplated previously in conjunction with
[0088] While the invention has been disclosed in conjunction with a description of certain embodiments, the detailed description is intended to be illustrative and should not be understood to limit the scope of the present disclosure. As would be understood by one of ordinary skill in the art, embodiments other than those described in detail herein are encompassed by the disclosed invention. Modifications and variations of the described embodiments may be made without departing from the spirit and scope of the invention.
[0089] It will further be understood that any of the ranges, values, properties, or characteristics given for any single component of the present disclosure can be used interchangeably with any ranges, values, properties, or characteristics given for any of the other components of the disclosure, where compatible, to form an embodiment having defined values for each of the components, as given herein throughout. Further, ranges provided for a genus or a category can also be applied to species within the genus or members of the category unless otherwise noted.
[0090] Finally, the qualifier “generally,” and similar qualifiers as used in the present case, would be understood by one of ordinary skill in the art to accommodate recognizable attempts to conform a device to the qualified term, which may nevertheless fall short of doing so. This is because terms such as “circular” are purely geometric constructs and no real-world component is truly “circular” in the geometric sense. Variations from geometric and mathematical descriptions are unavoidable due to, among other things, manufacturing tolerances resulting in shape variations, defects and imperfections, non-uniform thermal expansion, and natural wear. Moreover, there exists for every object a level of magnification at which geometric and mathematical descriptors fail due to the nature of matter. One of ordinary skill would thus understand the term “generally” and relationships contemplated herein regardless of the inclusion of such qualifiers to include a range of variations from the literal geometric meaning of the term in view of these and other considerations.
