DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to FIG. 1, FIG. 2 and FIG. 3, FIG. 3 shows a side elevational 
view of the invention of a cocktail container 10 comprising a receptacle 
12 supported by a tall support base 14. FIG. 2 is a side elevational view 
of the tall support base 16. FIG. 1 shows a side elevational view of the 
receptacle 12 which includes double-flared or teardrop shaped side walls 
20, 22 which converge downward from an open end 18 to a lower end 24 and 
terminates in a downwardly projection dual stage tapered plug 26. Such a 
double-flared or teardrop shaped receptacle 12 is often referred to as a 
"Margarita glass" even though it may not be made of glass and also 
referred to as "Margarita Stemware". The container 10 is used for other 
types of drinks such as "island" drinks and other similar cocktails or 
"frozen" drinks and further may be used for serving appetizers such as 
shrimp cocktails and desserts. 
Referring now to FIG. 1, FIG. 2, and FIG. 4, the upper stage 25 and lower 
stage 27 of plug 26 are each slightly tapered and the upper stage 25 is 
approximately 3/8 inch long and the lower stage 27 is approximately 1/4 
inch long although other lengths are equally feasible. The tapering of 
upper stage 25 facilitates a tight fit when the plug 26 is inserted into 
the open end of socket 30 of base 14 and base 16 and the tapering of the 
lower stage 27 facilitates a secure fit when the receptacles 12 are nested 
or stacked for packaging and shipping as shown in FIG. 6. 
Referring again to FIG. 1, the top of the upper flared portion formed by 
side wall 20 of receptacle 12 comprises the open end 18. The transition 
point 28 or top of the lower flared portion formed by sidewall 22, which 
resembles a truncated ellipse, is approximately one-half of the diameter 
of the open end 18, although other various diameters for the open end 18 
and the transition point 28 are equally feasible. The preferred embodiment 
of the invention is fabricated from inexpensive material such as 
polystyrene plastic which provides thin but sturdy walls 20, 22. The upper 
peripheral edge 17 of the cocktail container 10 is provided with an 
overhang or outwardly projecting, continuous lip or bend 19. 
Referring again to FIG. 2, an embodiment of a tall support base 14 is 
shown. The upper end 30 of the base 14 is open and functions as a socket 
for receiving the dual stage tapered plug 26 of the receptacle 12. The 
neck 31 of the base 14 is slightly narrower than the remainder of the stem 
15 which tapers outward moving downward to a lower end 32 which flares out 
to provide a stable base. The lower end 32 is open and dimensioned to 
provide a stable cocktail container 10. The diameter of the lower end 32 
is approximately midway between the diameter of the open end 18 of the 
receptacle 12 and the diameter of the transition point 28 at the top of 
the lower flared portion formed by sidewall 22. The lower end 32 of the 
base 14 is provided with a downwardly turned peripheral edge or skirt 34. 
The base is fabricated from plastic like the receptacle 12. 
Referring to FIG. 3, the side view of the cocktail container 10 is shown 
with the receptacle 12 of FIG. 1 supported on the base 14 of FIG. 2. The 
receptacle 12 of FIG. 1 may also be supported on a short stem support base 
16 as shown in FIG. 4. The tapered upper stage 25 of the plug 26 provides 
a tight connection for stability between the receptacle 12 and the base 
14. The lower stage 27 does not contact the side of the base 14. The 
primary function of the lower stage 27 is to enable safe nesting of a 
plurality of the receptacles 12 for efficient packaging and nonbreakage 
during shipping as shown in FIG. 6. 
Referring now to FIG. 4 and FIG. 5, FIG. 4 shows a side elevational view of 
an embodiment of the short support base 16. The stem 15 is reduced to be 
approximately two inches shorter than the stem of the base 14 shown in 
FIG. 2. In all other respects both bases 14, 16 are the similar. 
Referring now to FIG. 5, three tall support bases 14a, 14b, 14c are shown 
nested one on top of the other, each having an upper end 30a, 30b and 30c 
respectively. Four vertical stops 36 are positioned every 90 degrees 
around the inside wall of each tall base 14a, 14b, 14c approximately 0.5 
inches below the upper end 30a of the base 14a. The stops 36 limit the 
distance that base 14a can be inserted in another base 14b and so on. By 
maintaining a distance between the bases 14a, 14b and 14c in such a 
nesting configuration, any damage to said bases as a result of packaging 
and shipping is essentially eliminated. 
Referring now to FIG. 6, the nesting of several receptacles 12a, 12b, 12c 
is shown. The lower stage 27b of receptacle 12b is inserted into the upper 
stage 25a of a plug 26a of receptacle 12a and causes the receptacle 12b to 
be centrally positioned whereby the sides 22 and 23 of receptacles 12a and 
12b do not touch each other. Likewise, the lower stage 27c of receptacle 
12c is inserted into the upper stage 25b of receptacle 12b. A continuous 
plurality of receptacles may continue to be nested, limited only by the 
size of a packaging container. Hence, upper stage 25c may receive a lower 
stage of another receptacle. Having the lower stages 27a, 27b, 27c etc. on 
each receptacle is a significant advantage in order to prevent damage to 
the receptacles, especially during shipping or transporting of packaged 
receptacles. 
This invention has been disclosed in terms of certain embodiments. It will 
be apparent that many modifications can be made to the disclosed apparatus 
without departing from the invention. For example, the sizes of the 
receptacles 12 and the height of the support bases 14, 16 may vary. It may 
also be apparent that the subject container may have other applications 
besides serving drinks such as serving ice cream or serving shrimp by 
placing shrimp cocktail sauce in the bottom section of the receptacle and 
hanging shrimp around the peripheral top edge of the container. Therefore, 
it is the intent of the appended claims to cover all such variations, 
modifications and uses as come within the true spirit and scope of this 
invention.
