Abstract
Abstract The present invention relates to a system for coupling cylindrical sections to form an assembly of thermal or similar containers, where coupling to form the assembly is effected by an internally threaded connecting ring, normally carried at the base of an upper section, to the exteriorly threaded upper circumference of a lower section. The sections may be separated from one another internally to define chambers of discrete volume by screwing an exteriorly threaded section-separating into the upper and/or lower end of each cylindrical section.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
180 words
A system for coupling two cylindrical sections of a container, one above the other, comprising: first cylindrical means having external threads, second cylindrical means having internal threads and including a holding ring fixed within said second cylindrical means against rotation relative thereto; said one section having a lower end including circumferentially disposed internal threads and a circumferentially extending external groove; said other section having an upper end including internal and external circumferentially extending threads, said first cylindrical means engaging at least the internal threads of said one section lower end, said second cylindrical means being rotatably mountable on the lower end of said one section via engagement of said holding ring in said groove, said internal threads of said second cylindrical means being engageable with the external threads of said other section upper end, whereby upon rotation of said second cylindrical means relative to said one section, said second cylindrical means internal threads cooperate with said external threads of said other section upper end to secure the latter in firm proximal contact with the lower end of said one section.
Claim 2
Independent Claim
180 words
A system for coupling two cylindrical sections of a container, one above the other, comprising: first cylindrical means having external threads, second cylindrical means having internal threads and including a holding ring fixed within said second cylindrical means against rotation relative thereto; said one section having a lower end including circumferentially disposed internal threads and a circumferentially extending external groove; said other section having an upper end including internal and external circumferentially extending threads, said first cylindrical means engaging at least the internal threads of said one section lower end, said second cylindrical means being rotatably mountable on the lower end of said one section via engagement of said holding ring in said groove, said internal threads of said second cylindrical means being engageable with the external threads of said other section upper end, whereby upon rotation of said second cylindrical means relative to said one section, said second cylindrical means internal threads cooperate with said external threads of said other section upper end to secure the latter in firm proximal contact with the lower end of said one section.
Claim 3
Dependent Claim
24 words
The system of claim 1 wherein said first cylindrical means defines means for separating the volumes encompassed by said one and said other sections.
Claim 4
Dependent Claim
50 words
The system of claim 2, and further comprising packing means for engagement between the upper region of said one section internal threads and the uppermost edge of said first cylindrical means, said packing means defining means for preventing liquid contents in said one section from leaking into said other section.
Claim 5
Dependent Claim
26 words
The system of claim 1 wherein said first cylindrical means comprises an annular sleeve and also engages said internal threads of said other section upper end.
Claim 6
Dependent Claim
17 words
The system of claim 1 wherein both said one section and said other section are identically configured.
Claim 7
Dependent Claim
135 words
The system of claim 1 wherein said second cylindrical means comprises a sleeve and the internal threads of said second cylindrical means extend circumferentially about the inner surface thereof, said inner surface further including a plurality of spaced, radially outwardly directed grooves, each extending longitudinally of said sleeve and normal to said threads, and said holding ring comprises a plurality of spaced, radially outwardly directed projections for cooperative co-action with the grooves of said sleeve inner surface, said co-action of said projections within said grooves securing said holding ring against rotation relative to said sleeve while simultaneously permitting movement of said holding ring longitudinally relative to said sleeve, and thus permitting removal of said holding ring from the interior of said sleeve in order to effect disassembly of said coupling figure from said container section.
Claim 8
Independent Claim
183 words
A system for coupling cylindrical sections of containers, comprising: a plurality of cylindrical means having external threads and internal threads, and a holding ring fixed within the cylindrical means against rotation relative thereto; each cylindrical means having a lower end including circumferentially disposed internal threads and a circumferentially extending external groove; each cylindrical means having an upper end including internal and external circumferentially extending threads; each first cylindrical means engaging at least the internal threads of a lower cylindrical means located under the first cylindrical means; the lower cylindrical means being rotatably mountable on the lower end of the lower end of the first cylindrical means via engagement of the holding ring in the groove, the internal threads of the lower cylindrical means being engageable with the external threads of the upper end of the first cylindrical means, whereby, during rotation of the lower cylindrical means relative to the first cylindrical means, the internal threads of the lower cylindrical means cooperate with the external threads of the first cylindrical means to secure the latter in firm proximal contact with the first cylindrical means.
Claim 9
Independent Claim
183 words
A system for coupling cylindrical sections of containers, comprising: a plurality of cylindrical means having external threads and internal threads, and a holding ring fixed within the cylindrical means against rotation relative thereto; each cylindrical means having a lower end including circumferentially disposed internal threads and a circumferentially extending external groove; each cylindrical means having an upper end including internal and external circumferentially extending threads; each first cylindrical means engaging at least the internal threads of a lower cylindrical means located under the first cylindrical means; the lower cylindrical means being rotatably mountable on the lower end of the lower end of the first cylindrical means via engagement of the holding ring in the groove, the internal threads of the lower cylindrical means being engageable with the external threads of the upper end of the first cylindrical means, whereby, during rotation of the lower cylindrical means relative to the first cylindrical means, the internal threads of the lower cylindrical means cooperate with the external threads of the first cylindrical means to secure the latter in firm proximal contact with the first cylindrical means.
Claim 10
Dependent Claim
58 words
The system of claim 7 including an external ring perimetrically threaded on the inner surface thereof, which external ring is screwed to the external threaded surface of the upper area of each cylindrical means by freely rotating the ring with respect to the cylindrical means by means of a holding ring around the perimeter of the external ring.
Claim 11
Dependent Claim
39 words
The coupling system of claim 7, including separating internal caps with threaded external surfaces, wherein each cap screws into the upper or lower area of its respective cylindrical means, whereby the volumetric capacities of each cylindrical means are separated.
Claim 12
Dependent Claim
35 words
A coupling system according to claim 9, including a rubber packing ring located between the end and the lower edges of the internal connecting ring and the lower cylindrical means, preventing leakage between cylindrical means.
