Abstract
Abstract A two compartment package is described which consists of an outer spirally wound fiber can containing a dough product in one compartment thereof that is separated from a second compartment by a metal separator plate positioned transversely and engaging the inside wall of the container. On the other side of the separator plate is an icing cup which frictionally engages the walls of the container at its open end which faces the separator plate. The package is prepared by partially inserting the icing cup, closed end down, into the top of the can tube. The cup is then forced to the bottom and an end is then applied to the bottom of the can tube. The icing cup is filled. The separator plate and dough are then inserted and the can is sealed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
221 words
A multi-compartment dough container comprising a fiber can body of cylindrical configuration, end walls sealed to each end of the fiber container to close the ends thereof, a separator plate positioned in the cylindrical fiber container in a plane extending normal to the axis thereof and having a first interference fit therewithin, a cup between the separator plate and one end of the fiber container, the closed end of the cup facing the adjacent end of the container, the cup being formed from a thermoplastic resinous material, the lower edge of the periphery of the separator plate being in continuous contact with the upper edge of the cup and a second interference fit between the cup and the inner wall of the fiber container at a location adjacent to the said separator plate to thereby define a triple seal comprising a first seal between the separator plate and the adjacent circular section of the inner wall of the fiber container, a second seal between the separator plate and the cup and a third seal between the portion of the cup adjacent the separator plate and the inner wall of the fiber container, said triple seal being effective to reduce the extrusion of dough from the dough compartment above the separator plate into the space between the cup and the fiber contaIner.
Claim 2
Dependent Claim
221 words
A multi-compartment dough container comprising a fiber can body of cylindrical configuration, end walls sealed to each end of the fiber container to close the ends thereof, a separator plate positioned in the cylindrical fiber container in a plane extending normal to the axis thereof and having a first interference fit therewithin, a cup between the separator plate and one end of the fiber container, the closed end of the cup facing the adjacent end of the container, the cup being formed from a thermoplastic resinous material, the lower edge of the periphery of the separator plate being in continuous contact with the upper edge of the cup and a second interference fit between the cup and the inner wall of the fiber container at a location adjacent to the said separator plate to thereby define a triple seal comprising a first seal between the separator plate and the adjacent circular section of the inner wall of the fiber container, a second seal between the separator plate and the cup and a third seal between the portion of the cup adjacent the separator plate and the inner wall of the fiber container, said triple seal being effective to reduce the extrusion of dough from the dough compartment above the separator plate into the space between the cup and the fiber contaIner.
Claim 3
Dependent Claim
37 words
The container according to claim 1 wherein the separator plate comprises a metal disk having a downwardly turned peripheral edge to maintain the extreme peripheral edge of the disk out of contact with the inner can wall.
Claim 4
Dependent Claim
28 words
The container of claim 1 wherein the open end of said cut facing upwardly in the direction of the separator plate is sealed solely by the separator plate.
Claim 5
Dependent Claim
42 words
The container of claim 1 wherein the fiber container comprises a multiple wall fiber can including a central relatively thick layer of fiberous body stock and a liner composed of a laminate resistant to the flow of the moisture, vapor and oil.
Claim 6
Dependent Claim
38 words
The container of claim 1 wherein the cup has an open end thereof facing upwardly in the direction of the separator plate and the other end thereof is closed and said cup is formed from polymerized styrene resin.
Claim 7
Dependent Claim
73 words
The container of claim 1 wherein the cup has an open end thereof facing upwardly in the direction of the separator plate and the other end thereof is closed, said cup is formed from a polypropylene resin and the interference fit between the separator plate and the fiber container and between the cup and the fiber container are both between about 0.2 and 0.55 percent of the inside diameter of the fiber container.
