Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 136 words
A double compartmented combined popping and shipping package for popcorn comprising a supporting base including a first semi-rigid compartment having side and bottom walls and a second flexible compartment communicating therewith and having first and second parallel sheets of flexible material defining the upper and lower surfaces thereof, said first and second sheets being connected together at their edges and expansion pleats in the sheets to allow expansion of the second compartment, said second compartment being located outside the walls of the first compartment and being supported at the upper end of the first compartment to define the top of the package and being of sufficient size after popping to hold all of said popcorn after it has popped except that which remains in the first compartment, said second compartment being larger than the first compartment.
Claim 2
Dependent Claim 136 words
A double compartmented combined popping and shipping package for popcorn comprising a supporting base including a first semi-rigid compartment having side and bottom walls and a second flexible compartment communicating therewith and having first and second parallel sheets of flexible material defining the upper and lower surfaces thereof, said first and second sheets being connected together at their edges and expansion pleats in the sheets to allow expansion of the second compartment, said second compartment being located outside the walls of the first compartment and being supported at the upper end of the first compartment to define the top of the package and being of sufficient size after popping to hold all of said popcorn after it has popped except that which remains in the first compartment, said second compartment being larger than the first compartment.
Claim 3
Dependent Claim 16 words
The package of claim 1 wherein both of the compartments are formed from cellulosic sheet material.
Claim 4
Dependent Claim 38 words
The package of claim 1 wherein at least a portion of the large compartment is formed from a material that is not transparent to microwave energy to thereby at least partially shield the corn after it is popped.
Claim 5
Dependent Claim 114 words
A combined popping and shipping package for popcorn comprising a charge of unpopped corn, a relatively small compartment having side and bottom walls holding the unpopped corn and being on the order of the same size as the charge and a larger compartment separate and distinct from the small compartment having a pair of opposed connected walls and said larger compartment being connected to the small compartment on opposite sides of an opening and communicating therewith through said opening, whereby the large compartment receives the corn as it pops, the large compartment is a collapsed paper bag sealed at its ends and having longitudinally extending gussets to facilitate expansion thereof to accomodate popped kernels.
Claim 6
Dependent Claim 114 words
A combined popping and shipping package for popcorn comprising a charge of unpopped corn, a relatively small compartment having side and bottom walls holding the unpopped corn and being on the order of the same size as the charge and a larger compartment separate and distinct from the small compartment having a pair of opposed connected walls and said larger compartment being connected to the small compartment on opposite sides of an opening and communicating therewith through said opening, whereby the large compartment receives the corn as it pops, the large compartment is a collapsed paper bag sealed at its ends and having longitudinally extending gussets to facilitate expansion thereof to accomodate popped kernels.
Claim 7
Dependent Claim 16 words
The package of claim 4 wherein the small compartment is formed from semi-rigid flexible sheet material.
Claim 8
Dependent Claim 12 words
The package of claim 5 wherein the semi-rigid sheet material is paperboard.
Claim 9
Dependent Claim 44 words
The package of claim 4 wherein one side of the bag has a hole therein smaller in size than the distance between said ends of the bag and the edges of the hole are connected to the small compartment to define the communication therebetween.
Claim 10
Dependent Claim 150 words
A combined popping and shipping package for popcorn comprising a two compartmented container defined by a first relatively small compartment of a substantially fixed volume containing unpopped corn and a second relatively large compartment separate and distinct from the first compartment and communicating with the small compartment through an opening, the compartments being connected together adjacent to and on opposite sides of said opening whereby the corn when it pops is propelled by the force of the popping explosions from the small compartment to the large compartment, the small compartment is formed from semi-rigid cellulosic sheet material and is funnel shaped, the end most remote from the large compartment is formed to act as a supporting base and the large compartment comprises upper and lower rectangular sheets connected together at their edges and pleats are provided in the large compartment to permit expansion of the upper and lower rectangular sheets.
