Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
223 words
A container adapted to hold a soft-frozen extrudable comestible having a moisture content in excess of 30% by weight, said container being collapsible under hand pressure thereby forcing extrudable material contained therein through an orifice, said container being comprised of: (a) a collapsible, cone-shaped body portion having an open top and a circular top edge, said body portion comprised of an external cone-shaped paper jacket and an internal, heat-sealable, cone-shaped liner, said liner being bonded to said external jacket over less than 20% of the surface area of the liner such that an insulating layer of air is present between the liner and jacket in the unbonded areas, (b) a circular fitment sized to be received by and at least partially recessed within the body portion of said container, said fitment having a central aperture which functions as an extruder orifice and an upstanding rim around its periphery, (c) an engagement between said upstanding rim and said body portion, which secures the fitment in place such that it is not dislodged during an extrusion process, said engagement being affected by folding the top edge of the body portion over the upstanding rim of the fitment, and heat sealing the said body portion to said cone-shaped liner of said rim, and (d) a removable closure which extends across the aperture located in the fitment.
Claim 2
Dependent Claim
