Abstract
Abstract A multi-product dispenser package having two or more compartments separated by a partition or diaphragm wall, each compartment containing a different material or product and having means which when actuated will break, rupture or puncture the separating wall to permit the materials or products to comingle so that the comingled material or product may be dispensed from said container.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
331 words
A dispensing unit for dispensing non-pressurized materials comprising a container having an upper container with a body formed of a substantially rigid material with an opening in the bottom thereof and a separate lower container extending directly below the upper container, said lower container having a body formed of a substantially rigid material and having a top opening substantially that of the circumference of the lower container, a puncturable partitIon extending completely across the top opening of the lower container, said partition being planar and extending parallel with the bottom of the lower container and separating said upper and lower containers without reducing the volumetric capacity of each container so that each container separately contains a separate non-pressurized material, means for coupling said upper and lower containers adjacent the bottom of the upper container and the top of the lower container so that when coupled the bottom of the upper container is immediately adjacent the top of the lower container and they form an integral unit in which the circumference of the upper and lower containers are substantially the same circumference, an axially depressible member positioned within said upper container and manually depressible to engage and puncture the partition to permit the material within each container to be mixed while said separate containers are connected as a unit, said axially depressible member comprising a hollow tubular plunger having a discharge spout at the outer end in axial alinement with said tubular plunger and puncturing means at the opposite end for puncturing the partition, said tubular plunger having an opening at said opposite end adjacent said puncturing means so that when said tubular member is depressed the material in said lower container will pass into said plunger by gravity flow when the unit is inverted, said plunger having an opening communicating with the upper container through which the material passes and mixes with the material from the lower container before it is discharged by gravity flow through said axially alined discharge spout.

Dependent Claim

Claim 3
Dependent Claim
20 words
A structure as set forth in claim 1 in which the plunger has a cutting edge at the bottom thereof.
Claim 4
Dependent Claim
32 words
A structure as set forth in claim 1 in which the cutting edge is of an annular shape and has a bottom cutting edge which slopes downwardly to provide an inclined edge.
Claim 5
Dependent Claim
26 words
A structure as set forth in claim 1 in which means are provided for preventing movement of said plunger relative to said container during shipment thereof.
Claim 6
Dependent Claim
26 words
A structure as set forth in claim 1 in which the upper container has bellows which when compressed will actuate the plunger to rupture the partition.
Claim 7
Dependent Claim
30 words
A structure as set forth in claim 1 in which the upper container has bellows which when compressed will cause said movable member to move inwardly and puncture the partition.
Claim 8
Dependent Claim
24 words
A structure as set forth in claim 6 in which means are provided around said bellows to prevent collapsing of said bellows during shipment.
