Abstract
Abstract A product to be dispensed is packaged in an axially collapsible product bag in distinct transversely extending axial layers. When the product is dispensed, it enters into a discharge nozzle generally from the center of the bag with the result that there is an almost immediate combining of the product layers to be simultaneously dispensed in a striped stream.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
120 words
An apparatus for dispensing a striped product, said apparatus comprising a rigid container, a collapsible bag mounted within said rigid container, a dispensing valve carried by said rigid container in communication with the interior of said collapsible bag for dispensing the contents thereof, a product in said collapsible bag, and a gas in said rigid container around said collapsible bag for exerting a collapsing pressure on said collapsible bag to force said product towards said dispensing valve; the improvement residing in said product being arranged in said collapsible bag in distinct transversely extending axial layers, there being a single outlet passage between said collapsible bag and said dispensing valve and said collapsible bag being collapsible primarily in an axial direction.
Claim 2
Independent Claim
120 words
An apparatus for dispensing a striped product, said apparatus comprising a rigid container, a collapsible bag mounted within said rigid container, a dispensing valve carried by said rigid container in communication with the interior of said collapsible bag for dispensing the contents thereof, a product in said collapsible bag, and a gas in said rigid container around said collapsible bag for exerting a collapsing pressure on said collapsible bag to force said product towards said dispensing valve; the improvement residing in said product being arranged in said collapsible bag in distinct transversely extending axial layers, there being a single outlet passage between said collapsible bag and said dispensing valve and said collapsible bag being collapsible primarily in an axial direction.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1 wherein said product layers are composed of products selectively different in at least color, taste, texture and composition.
Claim 4
Dependent Claim
33 words
The apparatus of claim 2 wherein that one of said product layers disposed immediately adjacent said dispensing valve is thinner in height than at least the next adjacent one of said product layers.
Claim 5
Dependent Claim
33 words
The apparatus of claim 1 wherein that one of said product layers disposed immediately adjacent said dispensing valve is thinner in height than at least the next adjacent one of said product layers.
Claim 6
Dependent Claim
18 words
The apparatus of claim 1 wherein said collapsible bag has a pleated body for effecting said endwise collapse.
Claim 7
Independent Claim
90 words
A method of dispensing a striped product, said method comprising the steps of providing an axially collapsible bag having at one end thereof a centrally located dispensing valve, filling the bag with a flowable product arranged in the bag in distinct transversely extending axial layers, and applying a collapsing force to the bag while actuating the dispensing valve to effect discharge of the product from a radially central part only of the bag through a single dispensing opening with product portions of adjacent ones of the layers being simultaneously dispensed.
Claim 8
Independent Claim
90 words
A method of dispensing a striped product, said method comprising the steps of providing an axially collapsible bag having at one end thereof a centrally located dispensing valve, filling the bag with a flowable product arranged in the bag in distinct transversely extending axial layers, and applying a collapsing force to the bag while actuating the dispensing valve to effect discharge of the product from a radially central part only of the bag through a single dispensing opening with product portions of adjacent ones of the layers being simultaneously dispensed.
Claim 9
Dependent Claim
23 words
The method of claim 6 wherein said product layers are composed of products selectively different in at least color, taste, texture and composition.
Claim 10
Dependent Claim
16 words
The method of claim 6 wherein said collapsing force is applied by a surrounding gaseous pressure.
