• an issue with the cups 351 is that during the act of stacking one cup inside the other, an air flow is created that causes some of the powdered ingredients within the lower cup to get dislodged and trapped between the side walls of the adjacent cups.

Specifically, when some of the powder ingredient 361b is located in the space 370 between the first and second ones of the cups 351a, 351b, that powder ingredient 361b causes friction that increases the force required to split the cups.
• the powder ingredient may remain located on the exterior surface of nested cups (in this case, the first one of the cups 351a), which is undesirable because then the powder ingredient 361 becomes attached to a user’s hand when he/she grips the cup to consume the beverage.

• One of the benefits of including the plurality of apertures 445 (which could be a single aperture instead of a plurality of apertures in some embodiments) is that it provides a path for air to flow through as one cup is being inserted into the cavity of another cup during stacking of the cups to form the stack 470.

• the first and second portions 630, 640 of the sidewall are non-coplanar such that they intersect at an oblique angle.
• the first portion 630 of the sidewall 620 is oriented so as to diverge from axis D-D with increasing distance from the floor 610 towards the second end 602 of the cup 600.
• the second portion 640 of the sidewall 620 is either: (1) parallel to the longitudinal axis D-D; or (2) diverges from the longitudinal axis D-D with increasing distance from the floor 610 towards the bottom end 601 of the cup 600.
• the second portion 640 of the sidewall 620 of one cup 600 will wipe against the inner surface of the first portion 630 of the sidewall 620 of another cup 600 as the one cup 600 is being inserted into the cavity of the another cup 600.
• the first portion 630 of the sidewall 620 may have a first draft angle and the second portion 640 of the sidewall 620 may have a second draft angle, the first draft angle being greater than the second draft angle.
• the draft angle is the angle formed between the sidewall 620 and the longitudinal axis of the cup 600.
• the first and second portions 630, 640 of the sidewall 620 may intersect at an angle of between 160° and 179° in some embodiments, and more specifically between 170° and 178°.
• the second portion 640 of the sidewall 620 comprises a plurality of apertures 645 therein.
• the aperture 645 are slits notches, or cut-outs formed into the second portion 540 of the sidewall 620 and arranged in a circumferentially spaced apart manner.
• the apertures 645 extend from the bottom end 601 of the cup 600 towards the floor 610, thereby forming openings in the bottom end 601 of the cup 600..
• the apertures 645 may serve another function in this embodiment.
• each cup 600 being inserted into another cup 600 will have the second portion 640 of its sidewall 620 contact the sidewall 620 of the cup that it is being inserted into, there may be a desire for the second portion 640 of the sidewall 620 to have some flexibility.
• orienting the second portion 540 of the sidewall 520 as described may increase the separation force required to individually separate the cups during a dispensing operation the second portion 640 of the sidewall 620 may become deformed when being seated into the cup in which it is positioned.
• the second portion 640 of the sidewall 620 can flex inwardly during separation to assist with the separation process.
• FIG. 18 illustrates a cup 700 that includes features from the cup 400 of FIG. 11, the cup 400c of FIG. 14, and the cup 500 of FIG. 15. That is, the cup 700 includes a plurality of apertures 745 that includes notches 745a as described herein above with reference to the cups 400, 400a, 400b and through-holes 745b as described herein above with reference to the cups 400c. Furthermore, in this embodiment the cup 700 extends from a bottom end 701 to a top end 702.
• the cup 700 includes a floor 710 and a sidewall 720, the sidewall 720 comprising a first portion 730 that extends from the floor 710 to the top end 702 and a second portion 740 that extends from the floor 710 to the bottom end 701.
• the first and second portions 730, 740 of the sidewall are non-coplanar. That is, the first portion 730 of the sidewall 720 diverges with distance from the floor 710 towards the top end 702 and the second portion 740 of the sidewall 720 is either parallel to the axis of the cup 700 or diverges with increasing distance from the floor 710 towards the bottom end 701 of the cup 700.
• This combines all of the benefits of all of the variations of the cups described herein. Some of the benefits of the different embodiments described herein include having more reliable vending of cups and less powder or powder ingredient debris on the outside of the cups once vended.
• FIG. 19 illustrates a representation of a cup 800 in which the features described herein may be incorporated.

• the second portion 822 of the sidewall 820 is bent into a U shape, and the annular flange portion 812 of the floor 810 is positioned within the interior of the U shape formed by the sidewall 820.
• the exterior annular portion 823 of the second portion 822 of the sidewall 820 covers an outer surface of the annular flange portion 812 of the floor 810 and the interior annular portion 824 of the second portion 822 of the sidewall 820 covers an inner surface of the annular flange portion 812 of the floor 810
• any apertures, holes, or cutouts formed into the sidewall 820 as described above would extend through both legs of the U of the sidewall and through the annular flange portion 812 of the floor 810.
• the apertures, holes, cutouts, or notches extend through the exterior annular portion 823 of the second portion 822 of the sidewall 820, the annular flange portion 812 of the floor 810, and the inner annular portion 824 of the second portion 822 of the sidewall 820.

It should be readily appreciated by those skilled in the art how the concepts described above may be incorporated into the cup 800 shown in FIG. 19.
• the vending cups described herein may be formed from a paper- based material. Such vending cups may be made out of paper and then lined or coated with plastic or wax to prevent liquid from leaking out or soaking through the paper. Alternatively, the paper cups may be lined with a water-based dispersion barrier that is either free of plastic or includes such a small percentage of plastic that the paper cup is still able to be recycled in the standard paper waste stream.
• the invention is not limited to the cups being formed from paper in all embodiments and they could be formed from plastic, polystyrene, polypropylene, polyethylene, polylactic acid, metal, or the like in other embodiments.
