Abstract
Abstract A multi-compartment package for the packaging of food products takes the form of a generally flat rectangular pouch-like package which is permanently closed at the side edges, has a temporary seal at the top edge and a bottom closure. A further temporary seal extends between the top and bottom of the package separating the interior of the package into two separate compartments. The package is opened by separation along the temporary seals to result in a one compartment package open at the top. The invention has particular applicability to the packaging of the components of an ice-cream sandwich.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
A generally planar pouch-like package formed of overlying layers of heat-sealable flexible substantially air- and moisture-impervious material and having a generally rectangular shape with side edges and top and bottom edges, said package comprising permanent heat seals at each side edge thereof along which said overlying layers are not separable, a first temporary, separable heat seal closing the top edge of the package, a heat seal closing the bottom edge of the package, and at least one additional temporary, separable heat seal extending continuously from said top edge to said bottom edge intermediate said side walls and separating the interior of the package into separate compartments containing packaged items, said temporary, separable seals being so constructed that separation of the overlying layers may be effected therealong without otherwise damaging the integrity of the remainder of the package and the layers to permit opening of the package at said top edge to gain simultaneous access to the items packaged in said separate compartments and to permit formation of a single interior compartment by separation of the overlying layers along said at least one additional temporary, separable seal.
Claim 2
Dependent Claim
186 words
A generally planar pouch-like package formed of overlying layers of heat-sealable flexible substantially air- and moisture-impervious material and having a generally rectangular shape with side edges and top and bottom edges, said package comprising permanent heat seals at each side edge thereof along which said overlying layers are not separable, a first temporary, separable heat seal closing the top edge of the package, a heat seal closing the bottom edge of the package, and at least one additional temporary, separable heat seal extending continuously from said top edge to said bottom edge intermediate said side walls and separating the interior of the package into separate compartments containing packaged items, said temporary, separable seals being so constructed that separation of the overlying layers may be effected therealong without otherwise damaging the integrity of the remainder of the package and the layers to permit opening of the package at said top edge to gain simultaneous access to the items packaged in said separate compartments and to permit formation of a single interior compartment by separation of the overlying layers along said at least one additional temporary, separable seal.
Claim 3
Dependent Claim
56 words
The package of claim 1 wherein each of said compartments contains the components of a food product and at least one of said components is adversely affected by at least one other component upon long storage, whereby location of said components in separate compartments of the package hermetically sealed from one another inhibits said adverse affect.
Claim 4
Dependent Claim
20 words
The package of claim 1 wherein said overlying layers are directly joined in separable manner in each said temporary seal.
Claim 5
Dependent Claim
31 words
The package of claim 1 wherein one additional temporary, separable heat seal only is provided and extends between the top and bottom edge heat seals parallel to said side edge seals.
Claim 6
Dependent Claim
90 words
The package of claim 4 wherein one compartment contains a rectangular block of ice-cream and the other compartment contains two frangible edible wafers in face abutting relation, said compartments being dimensioned to minimize the air space in each compartment and to position the ice-cream block and wafers with their longitudinal axes substantially parallel to said side edges, whereby, upon opening of the package by separation of the layers along said temporary, separable seals, a single compartment open-topped package results from which said ice-cream block and wafers may be readily removed.
Claim 7
Dependent Claim
14 words
The package of claim 5 wherein said bottom edge has a permanent heat seal.
Claim 8
Dependent Claim
24 words
The package of claim 5 wherein said bottom edge has a temporary, separable heat seal, whereby said package may be opened at either end.
