Abstract
Abstract Improvements are provided in this invention relating to a slush cone assembly. The improvements are principally related to an insulating jacket for the slush cone and means for interlocking the jacket with the slush cone. The particular interlocking means take the form of molded plastic members along the outside of the walls of the slush cone and the inside walls of the jacket together with a flexible fingers for positively biasing the plastic members of the cone against the plastic members of the jacket.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
In a container for cooling a beverage having an inner cone for receiving the beverage, said cone having walls defining a cavity adapted to retain a refrigerant gel therebetween, the improvement comprising, in combination: an insulating thermoplastic jacket having a base and an upright wall connected to the base, said jacket adapted to receive said cone therein, and means for positively interlocking said cone with said jacket, wherein said positive interlocking means comprise a plurality of projections integral with the cone defined on the outer portion thereof and means for receiving said plurality of projections defined on the inner surface of said jacket and adapted to fit over and abut said projections when said cone is inserted and twisted in said jacket, and upwardly extending flexible fingers integral with the interior of the base of said jacket for contacting and upwardly biasing said cone when said cone is inserted in said jacket such that said cone may be positively secured in said jacket with said projections snugly biased against said projection receiving means.
Claim 2
Dependent Claim
173 words
In a container for cooling a beverage having an inner cone for receiving the beverage, said cone having walls defining a cavity adapted to retain a refrigerant gel therebetween, the improvement comprising, in combination: an insulating thermoplastic jacket having a base and an upright wall connected to the base, said jacket adapted to receive said cone therein, and means for positively interlocking said cone with said jacket, wherein said positive interlocking means comprise a plurality of projections integral with the cone defined on the outer portion thereof and means for receiving said plurality of projections defined on the inner surface of said jacket and adapted to fit over and abut said projections when said cone is inserted and twisted in said jacket, and upwardly extending flexible fingers integral with the interior of the base of said jacket for contacting and upwardly biasing said cone when said cone is inserted in said jacket such that said cone may be positively secured in said jacket with said projections snugly biased against said projection receiving means.
Claim 3
Dependent Claim
20 words
The improvement as set forth in claim 1 wherein said projections comprise rigid horizontal members molded integral with said cone.
Claim 4
Dependent Claim
37 words
The improvement as set forth in claim 1 wherein said projection receiving means comprise a plurality of horizontal members molded integral with the interior of said jacket at a predetermined distance from the base of said jacket.
Claim 5
Dependent Claim
39 words
The improvement as set forth in claim 1 including stop means for preventing movement of said cone in relation to said jacket beyond a predetermined point when said projections are positively biased below and against said projection receiving means.
Claim 6
Dependent Claim
29 words
The combination as set forth in claim 4 wherein said stop means comprise a plurality of rigid vertical members molded on the interior of and integral with said jacket.
Claim 7
Dependent Claim
43 words
The improvement as set forth in claim 1 wherein said flexible fingers comprise four flexible molded thermoplastic fingers integral with and extending upwardly from the base of said jacket, and fingers displaced symmetrically about the center of said base and tapering outwardly therefrom.
Claim 8
Dependent Claim
50 words
The combination as set forth in claim 6 including a knob member connected to and integral with the exterior of the base of said cone at the center thereof and adapted to cooperate with said fingers to compress said fingers further outwardly when said cone is urged into said jacket.
Claim 9
Dependent Claim
59 words
The combination as set forth in claim 7 including a second knob member connected to and integral with the interior of the base of said jacket at the center thereof and adapted to cooperate with and abut said first knob on said cone to prevent said fingers from being unduly compressed when said cone is urged into said jacket.
